It is installed separately and is movable.

Each of these handle plates 45a to 45h is individually provided with fish-like protrusions 46 for locking knitting needles, as shown in FIGS. 6 and 9, at a pitch of every eighth knitting needle 3. In this example, as particularly shown in FIGS. 10 to 12, the handle plate 45a has fishing protrusions 46 corresponding to the knitting needles 3 of the 10-point flea on the left side. The gold plate-like protrusion 46 corresponding to the knitting needle 3 on the left side 9 is attached to the handle plate 45.
The handle plate 45c is held by b, and as it slides to the right in the following order:
, 45d, 45e...45h, 45a, 45b
By repeating the arrangement order held by . Also, each handle plate 45a~h'
The fishing protrusion 4 is formed by the action of the spring 47 hooked on the left end of each
6 is held in an inactive position where it is arranged between the knitting needle 3 adjacent to the left without corresponding to the lower part of the knitting needle 3, but is pushed downward by movement to the right against the action of the spring 47. It can assume a working position in which the lowered knitting needles 3 can be locked.

In FIGS. 3, 5, and 6, 48 is a group of electromagnets that are Ryuichi machine conversion members, and is a one-needle electromagnet SLO~9, A~F (expressed in hexadecimal) that corresponds to twice the length of the handle plate 45. ing)
The bridge plate 50 is arranged directly above each electromagnet SL, and each front end of the bridge plate 50 is attached so as to be movable up and down with the rear end as a fulcrum. A moving force is given in the direction in which it is attracted to.

Reference numeral 51 denotes a U-shaped village arranged in a row so as to correspond to the one-needle electromagnet SL and the shaking plate 50, each of which has a rear leg 51a.
are threaded through the support frame 52 so that they can move up and down, and each of the rear legs 51a is supported by the ratchet so that the front legs 51b can swing in a horizontal plane, and the lift that always springs up on the lower surface of each of the rear legs 51a Due to the action of the biasing spring 53, the upper end of the rear chest 51a is attached to the lower surface of the front end of the shank plate 60.

54 is a cam ring arranged above the front leg of the U-shaped village 51;
It is connected to the pulley 22 via a bevel gear mechanism 55 so that one rotation of the pulley 22 makes three rotations, in other words, one rotation is made when the carriage moves 16 times of the knitting needles 3.

The cam mechanism 54 includes 16 lateral operating cams ACO to F as shown in FIGS. The length of each horizontal cam top surface is determined to be an angular range corresponding to approximately 4 pitches of the knitting needle, and the cam ring 54 is formed in a spiral shape as a whole so as to go around the cam ring 54. Arranged. Further, on the circumferential surface of the cam mechanism 54, one pair of push-down cams BCO to F are formed in a pair-wise relationship with each ratchet-actuating cam AC, and each having a phase shift of 180 degrees with respect to the same cam AC. , the shape of the cam surface bulging on each outer circumferential surface is as shown in FIGS. 5 and 6.
It gradually swells from the vicinity of both side hem edges of the corresponding mechanical action cam AC, and is defined to have a top surface over an angular range corresponding to approximately two pitches of the knitting needles. For convenience, in FIGS. 10 to 12, in order to clearly indicate the phase of the lateral actuation cam AC and the push-down cam BC, the cam surfaces are shown as being oriented in the same direction. Each press cam B of cam theory 54
C is brought into contact with the upper end of the front leg 51b of the corresponding U-shaped punch 51, and is lowered by the action of its cam surface against the elasticity of the upward biasing spring 53, and at its top surface position as shown in FIG. It is pushed down to a position below the solid line, that is, to a position where the upper end of the rear leg 51a is slightly away from the lower surface of the front end of the rocking plate 50.

For example, if the electromagnet SL is disconnected,
As the cam mechanism 54 continues to rotate, the upward biasing spring 53
In order for the elasticity of to overcome the elasticity of the tension coil spring 49,
The front end of the vibration plate 50 is floated along with the U-shaped village 51 returning along the circumferential surface of the cam BC toward the upper position shown by the chain line in FIG. At this time, the front leg 51b of the U-shaped village 51 enters the locus of motion of the lateral action cam AC, and as the cam wheel 54 continues to rotate, the front leg 51b of the U-shaped village 51 is acted upon by the lateral cam surface of the cam AC, causing the rear leg 51a to move. The front leg 51b swings as a shaft. However, if the electromagnet SL is energized,
In order to effectively hold the oscillating plate 50 in the position shown by the solid line in FIG. 5 by the electromagnetic force, the U-shaped village 51, which receives the elastic force of the upward biasing spring 53, cannot return upward and remains in the lowered position. will be put on hold. Therefore, even as the cam wheel 54 continues to rotate, the front leg 51b of the U-shaped village 51 remains below the locus of movement of the lateral actuating cam AC and remains unaffected by the cam AC. In Figures 5 and 6, 56
is a movable rod that is supported through the support frame 52 so that the intermediate portion thereof corresponds to the front leg 51b of each U-shaped village 51 and serves as a swinging fulcrum;
The handle plate 45 is configured such that the swinging motion of the front leg 51b is transmitted to a predetermined part of the handle plate 45, and the plate 45 is moved from the needle selection non-active position to the active position against the elasticity of the spring 47. It is inserted into the working hole 57 of and is operatively connected. moving rod 5
Since the number 6 is an integral multiple of 8, which is the number of handle plates 45, and is determined to be 16, the number of movable rods 56 connected to each handle plate 45 is 2, and the total number of movable rods 56 is 2. every 7th piece from
They are connected to the handle plate 45 in the order in which they are arranged. As shown in FIG. 6, the moving rod 5 is inserted into the handle plate 45 outside the specified position.
The front end of the plate 45 is inserted into a laterally elongated play hole 58 of the same plate 45, so that it is not operationally involved. In this example, the handle plate 45a has two movable rods 5 corresponding to the electromagnets SL0 and SL8.
6 are operatively connected, and the handle plate 45b has electromagnets SL1,
There are two moving rods 56 corresponding to 9, one corresponding to SL2 and A on the handle plate 45c, and one corresponding to SL3 on the handle plate 45d.
,SLB corresponds to SL4,C on the handle plate 45e.
The one corresponding to SL5,D is on the handle plate 45f, the one corresponding to SL6,E is on the handle plate 45g,
The handle plates 45M corresponding to SL7 and SL7F are operatively connected to each other. In FIGS. 3 and 6, when the belt 24 moves integrally with the carriage 13 or 20 connected thereto, for example, to the right, the cam wheel 54 similarly rotates via the pulley 22 rotating in the direction of arrow E in FIG. Since it rotates in the direction of arrow E, each mechanical cam AC sequentially acts on the one on the right side of the U-shaped village 51 relative to the one on the left side of the corresponding U-shaped village 51. In relation to the carriage movement of the main purpose, the action spreads to the neighboring objects one by one. Also, if the carriage moves to the left, the effects will spread from the right side to the left side. Therefore, in response to the vertical displacement of the U-shaped village 51, which is sequentially selected to be assisted or not assisted by the lateral action cam AC, the movable rod 56 is controlled to energize and de-energize the corresponding electromagnet SL. The needle selection control operation of leaving the handle plate 45 in the needle selection inactive position or moving it to the action position through the
It circulates in the same direction and at the same speed as the carriage movement. Furthermore, as clearly shown in FIG.
In relation to this, a handle plate 45 has a brocade-shaped protrusion 46 that can lock the butt 4 of the knitting needle 3 when it is pressed down.
is moved to the working position by receiving the action of the lateral action cam AC via the moving rod 56, locks the reduction knitting needle 3 to the fish-like protrusion 46, and moves the temporary low butt needle to the cam AC. The relationship is such that it is held only while being acted upon and released when it passes over the separation cam 19. Therefore, in order to accurately produce these timings, the carriages 13 and 20 are configured so that they can interlock only when the connecting pins 28 and 28a are locked in the connecting hole 27 of the belt 24, and In either case, the required timing is ensured. However, since the arrangement pitch of the connecting holes 27 is set to 8 pitches (36 pitches),
For example, even if the handle plate 45a moves to the weight needle action position when the green needle 3 corresponding to the copper-like protrusion 46 of the handle plate 45a is pressed down by the lowering cams 18, 18a of the carriage, the same plate It is not specified whether 45a is moved by the competitive action cams AC0 or 8; in other words, it is moved by either the lateral action cams AC0 or 8 depending on which of the connecting holes 27 the pin is seated in. determined, 18
A phase shift of 0 degrees will occur.

Therefore, when both the carriage and the belt are newly connected, the output signal of the phase element 32 is effectively utilized. In other words, in this example, as shown in FIG. 9, the knitting needles 3 are
At the point in time when the knitting needles 3 are approximately 11 pitches in advance, the handle plate 45 necessary for needle selection of each rope needle 3 is determined in advance, energization is started to the required electromagnet SL, and the knitting needle 3 is 5
It is determined that the energization of the electromagnet SL is terminated when the pitch has elapsed, and in particular, when the U-shaped village 51 is on the front side of the top surface of the push-down cam BC and is gradually being lowered. This is a setting to start energizing the electromagnet SL, but regarding the new connection between the carriage and the belt, etc., 180
It is determined which of the two push-down cams BC whose phases are shifted by degrees is at a rotational position suitable for starting energization, and the corresponding electromagnet SL also starts energizing.

In FIGS. 1, 5, and 13, 59 is a pattern card as a recording medium, for example, it is made of a material such as a translucent plastic sheet such as polyester that makes transparent writing possible and forms a paper surface. Become.

The card 59 is provided with feed holes 60 on both sides, and a large number of rectangular pixel areas 61 are formed in multiple stages by vertical and horizontal square lines 61a and 61b in the middle part, and in this example, one horizontal stage is 60 Consisting of 150 rows of pixel areas 61,
In order to clearly indicate each pixel area number when the leftmost pixel area 61 is set as ``1'' and sequentially taught to the right side, ``6 to ``12'', ``18''...``60'' as shown in the figure is used. In addition, in order to clearly indicate the number of stages when the bottom row is "1" and the number of rows is taught upwards, rows such as "5", "10", etc. as shown in the figure are displayed. It is noted. In addition, the card 59 has an instruction field 62 with a width of one square, which is formed by shifting the bottom row upward from the area 61 by an IZ square on the left side of the field where the pixel area 61 is formed. The bottom row corresponding to the pixel area 61 of the row is “1”.
” to indicate the number of steps when taught upwards, “5”, “
10"... is added, and furthermore, on the right side of the column of the pixel area 61, a small width thread is formed by shifting the bottom row upward by 13 squares from the column. There is an exchange column 65, and a row instruction 66 of "5↓"10"... that indicates the number of rows when counting upwards with the lowest row corresponding to the pixel area 61 of the "14" row as "1" is added. There is.

In the pixel area 61 column of the card 59, a knitting pattern 64 can be freely drawn by filling in the pixel area 61 selected according to the desired knitting pattern with black ink or the like having a lower light reflectance than the surface of the card 59. Alternatively, the recording type may be applied in advance. One pixel area 6
The size of 1 corresponds to the size of knitting stitches most often used in practical knitting techniques, and in this example, the stitch gauge of 40 stitches and 60 rows is 10.4c, which satisfies 10.8 skin. ,
A substantially actual-sized knitting pattern 64 is recorded by setting the pitch of the vertical square lines 61a to 2.6 ribs and the pitch of the horizontal square lines 61b to the 1.8 side. The small width thread exchange field 65 can be used, for example, on the left side of the needle bed 2 to replace the KHC-80 model "color changer for hand knitting machines (palier)" or the KRC-80 model "color changer for rubber knitting machines" currently on the market. By attaching it to the end, it is used to freely select four knitting yarns of different colors to knit colorful knitting works. Corresponding to the knitting yarn numbers ``1↓``2'', ``3to ``4'' added to the section, the squares of the knitting yarn to be selectively used at that time are filled in black.

It consists of a 4-phase stepping motor with 8 pulse motors and 2-2 phase excitation, and in this example, the step angle is 15 degrees.
) When moving one step forward or returning one step in the opposite direction, there is always a continuous rotational movement of 4 step angles (6
0 degrees), and is configured to perform one step of return. Specifically, after the rotation amount of 60 degrees, which is the rotational movement of 4 step angles, is decelerated to -5 times through the gear reduction mechanism 79, It is determined that the feed shaft 70 is rotated 1/30 times to advance or return the card 59 in stages corresponding to one stage of the card 59. In FIGS. 14 and 17, the manual feed dial 77 is connected to the gear 8 that meshes with the intermediate gear 74.
1, and is normally formed integrally with the gear 81. The snap ring 83 has elasticity in the axial direction. 83a, and the feed shaft 70 is manually rotated via a kind of friction clutch mechanism.
When the power is energized at 801 and the holding force at each step position is applied, a sliding rotation occurs in the manual feed dial 77, invalidating the manual rotation operation of the feed shaft 70.

When the pulse motor 80 is not energized, the holding force at each step position is weak, so the manual feed dial 77 and the flange portion 82 are kept in a compressed state, and the feed shaft 70 can be freely rotated by operating the dial 77. can be done. Moreover, since the gear ratios of the gears 81, 74, and 78 are such that one rotation of the dial 77 causes the feed shaft 70 to rotate by half, it is possible to easily obtain a minute amount of rotation with a light operating force. . Flange portion 82 and manual feed dial 77
When the required frictional force cannot be easily obtained due to the elasticity of the spring-like overwound piece 83a in the compressing state, that is, when sufficient transmission force for manual rotation of the feed shaft 70 cannot be obtained, The required transmission force can be easily obtained by forming appropriate uneven portions, for example, a plurality of chevron-shaped engaging portions on the pressure-contacting portions and engaging the respective valley portions.

3a, and at the stop position where the base 88 is in contact with the compression spring 91 at the left end, the high reflection coating further to the left of the light-transmitting window 73a facing the leftmost "1" pixel area 61. The first reading standby state corresponding to
It is determined that the vehicle is in a second reading waiting state corresponding to the high reflection coating further to the right of the light-transmitting window 73a facing the light-transmitting window 73a, and always performs one-way travel, either forward or backward. In FIGS. 1 and 5, the case cover 75 is provided with a protruding portion 104 with a card for inserting the card 59 into the reading mechanism 681, and is exposed to the outside through the card insertion hole 104a. , from the row position of the lowest pixel area 61 that can be observed from the front by the operator (indicated by arrow K in FIGS. 5 and 18), to the position that can be read and scanned by the sensor 92 (indicated by arrow J in ) to the pixel area 6
For example, the pixel area 6 of "2" stage corresponds to 1 of 1.
When the column 1 corresponds to the reading position J, the pixel area 61 of the "14" stage and the column of the instruction column 62 of "2" correspond to the observation position K.
In addition, a column of thread exchange column 65 of "1" exists in the same layer K.

Therefore, the sensor 92 selects the corresponding reading stage of the card 59 from the stage indication 63 corresponding to the observation position K.
For example, in the card set state where the set line 67 of the card 59 is aligned with the upper edge of the card insertion hole 104a, the card 59 can be moved 16 steps in the direction of the arrow G. Accordingly, the row of pixel regions 61 in the "1" stage can be made to correspond to the reading position J. In Figures 1 and 19,
Reference numeral 105 is a key SW operating mechanism disposed on the rear left side of the machine frame 1, which changes the knitting pattern 64 recorded on the card 59, which is a recording medium, to create a striped pattern. Various keys and switches (indicated by SW) are implemented as representative needle selection mode setting means for setting whether to implement the needle selection mode.

First, let us summarize the characteristics of the setting mode of the needle selection mode setting means in this example. First, the card 59
From among the knitting patterns 64 recorded in the knitting pattern 64, a pattern in an arbitrarily selected range in the course direction or the well direction is effectively used to continuously realize knitting patterns in units corresponding to the pattern width on the knitted fabric. Furthermore, the knitting needles 3 can be selected by arbitrarily specifying the reference position where the knitting pattern is to be realized.

As a second feature, in order to realize the knitting pattern in the range arbitrarily selected on the card 59 at the desired position on the green area, the needle selection range and reference position in which the knitting needles 3 should be selected on the needle bed 2 can be freely determined. can be specified.

Moreover, as a third feature, the knitting pattern recorded on the card 59 can be changed in various ways, such as reversing the left and right direction of the pattern, reversing the black and white of the pattern to perform the opposite direction, or changing the pattern. By freely specifying doubling in the horizontal direction, many knitting patterns can be created extremely easily. The fourth feature is that the knitting pattern can be changed in various ways in the row direction of the knitting, for example, the pattern can be doubled in the vertical direction, or the pattern can be repeated vertically without changing its vertical direction. You can freely specify that the pattern should be oriented vertically, or alternately change the top and bottom directions of the pattern vertically.
You can easily create more varied knitting patterns.

In addition, as a fifth feature, the range of knitting patterns that can be arbitrarily selected on the card 59 is set to "Moyo A" and "Moyo B."
The knitting needles 3 can be sorted according to the mist needle range and reference position, which can be specified separately for each pattern in the selected range, and can be specified independently from each other for each pattern in each selected range.

Furthermore, as a sixth feature, a so-called call-answer type data input format is adopted in order to specify each of the above ranges and reference positions, and by operating the calendar number key in response to each call display, each Data can be entered freely. Moreover,
The seventh feature is that the contents of each range and reference position specified at any given time can be freely recalled and confirmed, and can also be partially corrected. In addition, this example can be used to freely knit various types of knitting, such as double knit striped and sease knitting, using the already well-known so-called "color changer for rubber knitting machines", and furthermore, it is possible to handle knitting failures.

The operating circuits of each part that form digital electrical signals suitable for consolidating into a microcomputer are shown in Figures 21 to 34.
The diagram will be explained.

In FIGS. 21a and 21b, 124 is the VIDEO element 33
The positive terminal (5V) of the DC power supply is connected to each terminal of "15V" in the figure (the same applies hereinafter), and the light emitting diodes 33a and 33c are connected to the current limiting resistors 125 and 12, respectively.
6, and the phototransistor 3
Load resistors 127 and 128 are connected to the emitters of phototransistors 3b and 3d, and the emitter output signal of one of the phototransistors 33b is waveform-shaped via a Schmitt circuit 129 and then output as an output signal of "VIDEOI". , the emitter output signal of the other phototransistor 33d is output via the Schmitt circuit 130 as a digital electric signal of "VIDEO2".

FIG. 22b shows output waveforms at various parts of the operating circuit 124. For example, when each phototransistor 33b, d and the protrusion 31 of the sign disk 29 face each other as shown in FIG. 22a, In the figure b, each output signal on the chain line M is obtained, and when the disk 29 rotates in the direction of arrow FWD (rightward), an output signal that shifts to the right side in the figure is obtained.

As is clear from FIGS. 23 to 26, when the carriage runs to the right, the "VIDEOI" signal is changed to "VI
The phase will be delayed from the “DEO2” signal, and when the carriage moves to the left, “VIDEOI” will also be delayed from the “VID
The phase is advanced from that of ``EO2''. Moreover, “VIDE
"OI" falls from "H" to "L", or "L"
The cycle of rising from "H" to "H" is related to the timing of the movement of the carriage, and is related to the pitch of the green needle 3, so that one pulse is output for each green needle 3. In particular, in this example, the right The point at which the "VIDEOI" signal rises from "L" to "H" when the carriage is running coincides with the point at which it falls from "H" to "L" when the carriage is running to the left, and each time point is on the carriage center line. This also coincides with the point in time when C or D corresponds to the approximate center position between the green needles 3.
In FIG. 28, 131 indicates left and right reference elements 38, 40.
is an operating circuit (carriage detection circuit), and each element 38,
After the output signals of 40 are inverted and amplified by respective obeamps 132 and 133, two comparators 134 and 135 are applied.
, 136, 137.

Output signals of the left and right reference elements 38, 40 (Obeamp 13
The negative input terminal voltage of 2,133 (on the contrary, the positive input terminal voltage changes) is based on the NS polarity when the magnet 42 of the K carriage 13 approaches, as shown in FIG. Therefore, the "carriage detection signal" of high level VH is output from the obeamps 132 and 133, and the magnet 4 of the L carriage 20
4 is close to each other, the output voltage becomes Vh higher than the normal output voltage based on the SN polarity, and therefore the obeamp 132,
133, a lower level "carriage detection signal" is output. The comparators 134 and 136 are the obeamp 132,
It is used to determine the KL carriage IJ based on the "carriage detection signal" from 133, operates with reference voltage V2 as the level boundary, and inverters 138 and 139 in the subsequent stage
The comparators 135 and 137 similarly operate with the reference voltage VI as a level boundary, thereby outputting the L carriage signal LPI of "H".

The OR circuit 140 connected to the inverter 138 and the comparator 135 outputs an "H""leftreference" signal when either of them is input, regardless of the distinction between the K carriage signal KPI and the L carriage signal LPI. , Also, the OR circuit 141 connected to the inverter 39 and the comparator 137 similarly receives the K carriage signal KPI or the L carry signal IJ.
The OR circuit 142 connected to the comparators 135 and 137 outputs a "right reference" signal of "H" when the digital signal LPI is input. Even when the river is close, a "KL determination" signal of "H" is output when the L carriage signal LPI is input.

30a and 30b show the output waveforms of each part of the operating circuit 131 with specific correspondence between the magnets 42, 44 and the reference elements 38, 40, etc. A reference signal of "H" is output at an interval corresponding to the pitch, and when the carriage is running to the right at approximately the halfway point, "VIDEOI" rises from "L" to "H".
When driving to the left, the positional relationship similarly falls from "H" to "L", and the effective interrupt operation at each point in time (details will be described later) is specified as "left reference" or "right reference" control. There is.

After the output signal is waveform-shaped by the Schmitt circuit 146, it is output as a "phase" signal.

FIG. 32 shows the output waveform of the operating circuit 143, and each time the element 32 corresponds to the three upright walls of the sign disk 29, the "phase" is The signal is output as an "L" electrical signal corresponding to the digital code word "0", and in the portion where the upright wall 30 is not present, it is also output as an "H" electrical signal corresponding to the digital code word "1". Ru. By the way, in the interlocking relationship between the code disk 29 and the cam mechanism 54 using the belt 24 as a driving source, when the phase element 32 corresponds to the middle of the three upright walls 30 of the code disk 29, the cam wheel 54 Lateral action cam AC9,
ACA is operating the U-shaped punch 51 and the upright wall 30
When corresponding to the middle of the part without
, AC2 are assembled so that the U-shaped village 51 is in operation.

Therefore, for example, when the magnet body 42 of the K carriage connected to the belt 24 approaches either of the reference elements 38, 40, the phase element 32 is moved counterclockwise from the middle of the three upright walls 30 on the sign disk 29. The position corresponds to a position offset by two pitches of the striped needles 3 in all directions, or a position offset by two pitches of the knitting needles 3 in the counterclockwise direction from the middle of the part where there is no standing wall 30, and When the lateral operating cams AC7 and AC8 of the cam wheel 54 are operating the U-shaped punch 51'
Well, the element 32 corresponds to the upright wall 30', and the horizontal operation cam AC
When the F, ACO is operating the U-shape 51, the element 32 corresponds to the portion where the upright wall 30 is not present.

Furthermore, when the magnet body 44 of the L carriage connected to the belt 24 approaches either of the reference elements 38, 40, the phase element 32 moves the knitting needle clockwise from the middle of the three upright walls 30 on the code disk 29. 3, the position shifted by 2 pitches,
Alternatively, it corresponds to a position shifted clockwise by two pitches of the knitting needles 3 from the middle of the part without the upright wall 30, and moreover, the lateral actuating cams ACB, A of the cam wheels 54
When the CC is operating the U-shaped punch 51, the element 32
corresponds to the standing wall 30, and the competitive forces AC3 and AC4 are U
When the letter-shaped punch 51 is in operation, the element 32 is connected to the upright wall 3.
It corresponds to the part without 0.

As described above, regardless of whether the K carriage or the L carriage is used, the "phase" signal outputted when approaching either of the reference elements 38, 40 is "0" or "0".
1'', the rotational position of the cam wheel 54 can be detected, and the connection relationship between the carriage and the belt 24 can be known.

In FIG. 33, 157 is the operating circuit of the sensor 92;
The light emitting diode 94 is driven with direct current through a current limiting resistor 158, and a load resistor 159 is connected to the emitter of a phototransistor 97, so that the transistor 97 receives light from an obeamp 156 that constitutes a forward-rotating amplifier circuit at the subsequent stage. An analog electrical signal of ``rH'' is output as a ``sensor output'' depending on the amount of light, and specifically, as shown in Fig. 34a,
When the sensor 92 corresponds to the highly reflective coating of the guide plate 73, as shown in FIG. When scanning a pixel area 61 on which no pattern is drawn, the light reflected from the card surface or transmitted through the power cord is reflected again from the front surface of the guide plywood 72, and the level is slightly lowered to a medium level. When it becomes VM and scans the pixel area 61 where the pattern 64 is drawn, the level further decreases to the low level VL.

Comparator 16 is used to separate and form a data pulse from the "sensor output" signal, and when there is a "sensor output" at a level lower than the reference voltage VI as the level boundary, the data pulse becomes "H". DPI is output, and further passed through an inverter 161 to output an "L" data pulse DP2.

The comparator 162 is used to separate and form the read clock pulse from the "sensor output" signal, and operates with the reference voltage V2 as a level boundary, as shown in FIGS. 34a and 34b. "L" corresponding to the film
Thus, a digital electric signal that becomes "H" is output as a "CLOCK" signal corresponding to each transparent window 73a. OR circuits 164 and 165 with inverting input terminals are connected so that they constitute a latch circuit, and one OR circuit 1
It enters a set state using the data pulse DP2 inputted to 64 as a trigger, and outputs an "H" set output signal from its output terminal as a "card data" signal.

In addition, the other OR circuit 165 includes a Q output terminal of a monostable circuit 166 that outputs an "L" constant width reset pulse RP using the fall of the signal obtained by inverting the "CLOCK" signal by the inverter 163 as a trigger. As a result, each time the "CLOCK" signal rises, that is, each time the sensor 92 enters each transparent window 73a of the guide plate 73, the "CARD DATA" signal is cleared to "L". The input of the next data pulse DP2 is specifically anticipated.

At the same time, a clock pulse (2) with a period of 2 seconds is applied, and a RESET reset signal is commonly input to each RESET terminal from the power-on reset circuit 168 shown in FIG. I'm trying to get started. The IR rule terminal of SPUI has

The decode output terminal of [5} is set to "L" output. The second decoder DE2, which inputs only the output signal of the boat P3 after being inverted by the inverter 173, is also composed of an 8CD-TO-DECIMAL decoder, and is ramped according to the boat output data "A' to "D". It operates to selectively light up LIO to L13, and specifically, the lamp LI

By selectively setting them to "H" output,
The lamp driving transistors 174 and 1 are connected to each other so as to light up the LR lamp L17 or the error lamp L14.
75 and is preliminarily connected to the internal PLA including the output port 04.

. The programmed output port 05 (06 and 07 are not used) triggers the monostable circuit 176 connected to it at the falling edge of the "L" set output, and turns on the transistor 177 to generate a built-in oscillator. electronic buzzer B
Make S sound like 9 islands for a certain period of time. The boats P0 and PI of the parallel output boat P of the SPU2 are used to control the stage feeding of the card 59, and are connected to the drive circuit 1781 of the pulse motor 80 via the two AND circuits 154 and 155 shown in FIG. When this connection is made and the set signals of "rH" and "L" shown in FIG. The required excitation windings MDI to MD4 of the pulse motor 80 are energized through the pulse motor 80.

The other input terminal of the two AND circuits 1 64 and 155 is given the RESET signal output from the power-on reset circuit 168 of FIG. motor 80
In addition, as SPU2 starts control operation by releasing the reset signal, each boat P0, PI
The pulse motor 80 can be controlled by passing the set output signal as it is.

The parallel output boats 00 to 03 of the SPU 2 are programmed by the PLA in the same way as the output boats 04 to 07, and among these, the boats 00 to 02 are connected to the DC motor drive circuit 185 shown in FIG. For example, when the boat 00 outputs "rH", the transistors 86 to 188 for forward rotation are turned on, driving the DC motor 86 in forward rotation, causing the sensor 92 to travel forward in the right direction, and ending the forward travel. When the boat 00 remains at "H" and the boat 02 is outputted at "H", both the forward and reverse holding transistors 89 and 190 are turned on, reducing the current flowing to the DC motor 86. That is, the base 88 is held in the second reading waiting position where the right side compression spring 90 hits the holding current state in which the normal rotation force is weakened.

In addition, when the boat 01 is set to the "H" output, the reversing transistors 191 to 193 are turned on, and the DC motor 8 is turned on.
6 is reversely driven, the sensor 92 is caused to travel backwards to the left, and at the end of the backward travel, the boat 01 is set to "H".
When the boat 02 continues to output "H", both forward and reverse holding transistors 189 and 190 are turned on, reducing the current flowing to the DC motor 86, that is, weakening its reversing force. As the holding current state, the base 88
is held in the first waiting position where the left compression spring 91 is applied.

On the other hand, the output latch ports RO to RII of the SPUI and the parallel output boat P are used to control the power on/off of the electric converter village 48 consisting of the 16 electromagnetic ZSLO to SLF, and the boats RO to RII are , each port number and S

Boats 00 to 02 of the parallel output boats 00 to 03, which are programmed in advance by the internal PLA, including the output boat 03, are used in the display drive circuit 197 to dynamically drive the segment elements SEO to SE2. By setting boat 00 to "H" output, SEO lights up, by setting boat 01 to "H" output, SEI lights up, and by setting boat 02 to "H" output, SE2 lights up. I have to. A RESET signal is applied to the inhibit terminal BI of the decoder DE3 from the power-on reset circuit 168 shown in FIG. 36, and segment data output immediately after power-on is temporarily inhibited to prevent flickering display of the segment elements SEO to SE2. .

In addition, the SPU 2 scans various keys and switches SW, controls the drive of the pulse motor 80 and DC motor 86, performs card handling control, and also controls the transfer of detection data to the MPU. I will do it, but
Data representing each control start command is provided by the MPU at the required time. That is, all electrical control parts of the system are controlled by the MPU, and SPU1 and SPU2 assist in various specific control operations such as key SW scanning and card feeding. A bus line for data transfer is secured between them.

In FIG. 41a, 205 is an additional circuit for ensuring data retention when the power of the external RAM is turned on and off.
As shown in FIG. 41b, the voltage supplied to E2 is made to rise slower than the DC power supply voltage of the "15V" line when the power is turned on, and to fall earlier when the power is turned off.

Further, 206 is a so-called battery check comparator for the dry battery 202, and its negative input terminal is connected to the dry battery 202.
By operating with the minimum output voltage required to protect the external RAM, or a slightly higher voltage Vs in consideration of safety, as the reference voltage (12.5 V in this example). , in a normal state higher than the reference voltage Vs, it is "L" as a battery OK check signal.
An electrical signal of "H" is supplied to the serial input terminal SI of the SPUI in FIG. 35, and if not, an "H" electrical signal is supplied as a battery error. In the address structure of the external RAM shown in FIG. 42, details of the contents of each flag allocated as the system flag memory are as follows.
This is the same as the contents of the flag register of the MPU shown in Fig. 45, and the contents of a part of the flag register (Y addresses 0 to 3) are stored mainly for the purpose of protecting the flag contents when the power is turned off. , will be effectively used when the power is turned on next time. The address portions indicated by "■~m'" in the outer section are used as step memos for storing the input data that has been calculated in response to the lighting display of the lamps L2 to L13, respectively. For example, the layer number data corresponding to the lamp L2 is stored in the address part of "Onnadai stage {2}", and the calendar number data also corresponding to the lamp L3 is stored in the "final stage {3}".
``A'7'', which requires left and right data in addition to the calendar date and night.
”, etc., each word is (A4-7

, "■, [1■]" are always stored with data that does not distinguish between left and right, that is, data of "0". Further, in the address portion of "DN REG" for the number of stages (middle stage), the number of stages of the pixel area 61 that the sensor 92 corresponds to on the card 59 or the number of stages of "0" as card set data is stored. External R shown in Figure 42
In the address structure of AM, each address part of "right right" and "right left" is assigned as a card data memo which is the first storage device, and for example, the "right right" which is the first storage unit.
The digital electrical signal obtained when the sensor 92 scans forward toward the right, specifically, the "card signal" output from its operating circuit 157 (FIG. 33) is stored in the memory.
The "data" signals are stored in output order starting from bit address "0" up to bit address "59", and the "card data" signals are stored in the second storage section "right left" memory in order from bit address "59". Bit address “0”
When the sensor 92 scans backward to the left, the resulting "card data" signal is In the "correct right" memory, the "card data" signal is stored in order from bit address "59" to bit address "0" in order of output, and in the "correct left" memory, the "card data" signal is stored in order from bit address "0" to bit address "0". 59'' are stored in output order.

These first and second memory sections, ``correct right'' and ``correct left'' memories, correspond to the pixel area 61 on the card 59 that is scanned by the forward or backward movement of the sensor. , each bit corresponds to one pixel area 61, and is always set to "1" regardless of the direction in which the sensor 92 travels.

The signal based on the pixel area 61 of "2" is stored in the bit address "0" of the "right right" memory and the bit address "59" of the "right left" memory, and the signal based on the pixel area 61 of "2" is stored in the bit address "1" of the "right right" memory. , bit address "58" of "positive left" memory
The signal based on the pixel area 61 of "60" is stored at the bit address "59" of the "right right" memory and the bit address "0" of the "right left" memory. ” will be stored.

That is, the "right right" memory contains the pixel area 6 on the card 59.
1, the data is stored in the same order of bit arrangement, and in the "right left" memory, it is stored in the order of bit arrangement reversed left and right. Details of this bit address are partially illustrated in FIG. In the external RAM shown in FIG. 42, the address portions indicated by "data set memo" and "data change memo" each have an address of at least 200 bits for each knitting needle 3 on the needle bed 2.
The second word corresponding to the knitting needle 3 is assigned as a digital device, and each bit content corresponds to the knitting needle 3 in a one-to-one relationship. The electric signal is stored, and the bit address corresponding to the leftmost striped needle on the needle bed 2, that is, the knitting needle No. 100 on the left, is set to "202", and the bit address corresponding to the knitting needle on the right side of the knitting needle "Left 9" is set to "202".
The bit addresses corresponding to the knitting needles of "Boss flea" are taught in order such as "201", so that the bit address corresponding to all the needles of "Right 10 flea" can be specified as "399".

FIG. 42 partially illustrates the bit address structure of "200 to 399" in these "data set memo" and "data change memo". Data memory RAM (hereinafter referred to as internal RAM) configured inside the MPU
M) has the address structure shown in FIG. 43, and the details of the contents of each flag assigned as a system flag register (flag register) are as shown in FIG. 45, and the working register The contents of each register assigned as are shown in FIG.

In the internal RAM of the M circle U shown in Fig. 43, the "Nd" register for counting the SL number, in particular, counts with the IS Hayabusa number of "0 to F" corresponding to the number of the electromagnet SL of the above-mentioned 1 needle. ``C REG'' for carriage counting is a soft counter that represents the carriage position on the needle bed 2 and specifies the bit address of the ``data check memo'' in the external RAM. It is a soft counter that performs a counting operation of at least "200 to 399", and in practical terms counts beyond this range. "KO, KI" also for ADDR count
, "KO, KI" register is a soft counter that performs a counting operation of "0 to 59" so as to specify a bit address common to "correct right ↓" correct left, which is the first storage device, and also for transfer. ``D・REG'' D2 to D river, number of layers Stores the number of layers data to be displayed, etc., and is effectively used especially when data is transferred from the MPU to the SPUI. On the other hand, the internal RAM of the SPUI has the address structure shown in FIG. 48, and the details of each flag assigned as the system flag register and working register and the contents of the register are as shown in FIG. In particular, the transfer registers ■, ■, ■ store the layer number data transferred from the MPU, and "D・REG" D2 to DO also store the data obtained by adding so-called zero erasure processing to the contents of each register. It is effectively used for subsequent display control.

In addition, the "2 (N)" register is a soft shift register for counting the SL number, and the "3 (N)" register is an electromagnetic shift register.
This is a soft shift register for L ON/OFF data. The internal RAM of SPU2 has the address structure shown in FIG.
As shown in the figure.

Now, the specific control operations of the MPU and SPUs 1 and 2 consisting of the above-mentioned configurations can be understood from the flow diagrams shown in FIGS. 57 to 93, and the details will be explained below.
The explanation will be made with reference to the address configuration diagrams shown in FIGS. 42 to 49.

First, the control operation of the SPUI will be explained as shown in FIGS. 57 and 60 to 63.

- To explain according to the diagram, in the main flow of Fig. 60, the SPUI starts control operation starting from "0" of the program counter by power-on reset, and first clears the system and clears all OL boats 00 to 03. By outputting "L", the segment display on the calendar number display section 111 remains extinguished, and "0" is output to the P boat to set PO to P3 to "L", and the boat R
O to RII are set to "L" output, and all electromagnets SLO to SLF are placed in a power-off state. Next, the SPUI takes in the battery check signal applied to the serial input terminal SI as 4-bit data in synchronization with the internal clock signal, and if at least one of the bits is set to 1, “8” is displayed on the counterfeit number display section 111 every second.
88" blinks to indicate a battery error. Specifically, "8" for OH boats 04 to 07.
Boats 02, 01, 0 with numerical data output
0 is set to "H" sequentially every 200 French seconds, and the data of "888" is displayed in segments on the calendar number display section 1 1 1.The lighting operation is based on a dynamic drive method, and the boat 02
.about.00 are all set to "L" output and the light-off operation is repeated alternately at predetermined time intervals. That is, when control of the system is started by turning on the power switch 123, etc., the output voltage of the dry battery 202 is checked every time the power is turned on, and if it is determined that it is inappropriate for protecting the memory of the external RAM. , "888" is displayed blinking on the calendar number display section 111 to notify the operator. In this battery error state, the SPUI does not shift to the normal control flow, and the M-circle U does not operate normally. If SPUI determines that there is no battery error, it writes "0" as "standby mode" in the mode setting register, and then stores initial data "1" in the transfer number TR register. ,■Ask about the contents of the cash register.

If ■register is ``1'', the mode is ``front mode'', but since ``0'' has been written previously, the mode is ``standby mode'', and a timing check operation is performed. That is, the SPUI has a relationship in which the data that is the basis of control is transferred from the MPU. Specifically, when the MPU transfers data according to the timing flow shown in FIG.
Number of layer data of "A" representing "K carriage without needle selection", data of "B" representing "K carriage with needle selection",
Similarly, "C" for "L carriage without needle selection", "D" for "L carriage with needle selection", and several layers of "0" to "9" and "F" representing each digit content of "display data" By setting the data in ports R12 to R15 in advance and then outputting "L" from port 05, the SPUI
3 is checked to determine whether this is an "L" signal transfer command. Then, the SPUI repeats the operation of constantly checking the boat R13 in the "Samurai period mode" and waiting for data transfer from MenU, and if the boat R1
3 is an "L" input, the data transferred through the boats KO to K3 is immediately stored in the cash register (2), and the boat R14 is outputted as "L" to notify M-en U of the completion of the transfer.

When the MPU confirms the completion of this transfer on boat R9 and outputs data "F" to boats R12 to R15, returns boat 05 to "H" again.
After returning the value to "H", various control operations based on the transferred data are immediately executed according to the main flow shown in FIG. For example, when the transferred data is "A" to "D", the transferred data is stored in the register, and then the MP
The data transferred from U is specifically entered into the same timing check operation as described above, and the "electromagnet SL number" data transferred following the "needle selection presence/absence" data is transferred, and this is ■Store in the cash register.

■Based on the cash register contents, if this is "A" or "C" representing "no needle selection", the electromagnet SL is turned ON,
The contents of each address in the shift register 3 (N) register for OFF data and the shift register 2 (N) register for the number of the electromagnetic right SL are shifted to the right by words, and specifically, the contents of Y address E are shifted to the Y address. Japan, transfer the contents of Y address D to E in the same order, transfer the contents of Y address 0 to Y address -, and then 3 (N)
Y address of cash register Kawako, electromagnet SL as "no needle selection"
In addition to storing "1" data for turning on electricity (ON), 2 (N) Y address 01 of the cash register also stores the number data of the electromagnet SL, which is the customer inside the cash register, and ■ the register contents are "B". ” or “D”, the same 3 (N) register and 2 (
N) After shifting the contents of each address of the register to the right, enter "0" data in the Y address (0) of the 3rd (N) register to turn off the electromagnet SL as "needle selection failure". 2 (N) Register Y address (
0): ■ Store the S-receipt number data of the cashier's customer. The SPUI then follows the flow in Figure 60, in this example:
As the K and L carriages 13 and 20 travel, the needle data of the knitting needles 3 corresponding to the center lines C and D are sequentially read out, regardless of the direction of travel, and as shown in FIG. Since the setting is such that the electromagnet SL is quickly de-energized in advance by 11 pitches of the bridge needle 3 from the needle selection point F, the K carriage 13 travels an additional 13 pitches of the knitting needle 3 from the time the needle selection data is read. At that point, the electromagnet SL is energized or de-energized based on the argument data, and the L carriage 20 operates so that the electromagnet SL is energized or de-energized when the carriage has further traveled one pitch of the knitting needles 3.

In other words, the SPUI is in a relationship where the data of "needle selection or not" is transferred from the MPU in an orderly manner in relation to the movement of the entire needle 3 of the carriage one pitch at a time. If it is "K carriage" data of "B",
2 (N) Select the output boat corresponding to the SL number of the internal customer at Y address D of the cash register from RO to RI1, PO to P3, and select ON, OF, which is the internal customer of Y address D of the state cash register.
Based on the F data, if it is “1”, the corresponding boat is “
If it is set to "H" to energize the electromagnet SL, and if it is "0", it is set to "L" to de-energize the electromagnet SL.

In addition, ■ "L carriage" where the contents of the register are "C" or "D"
If it is data, select the boat corresponding to the contents of Y address 1 of 2 (N) register in the same way, and output “H” and “L” based on the contents of Y address 1 of 3 (N) register. When performing a set, if the data transferred from the MPU is one of "0" to "9" or "F", the SPUI determines this as calendar number (display) data, Total 3
In order to transfer digit data, the first transfer date is set.■
After transferring the contents of the register to ◎ register, perform the same timing operation as above again, transfer the second transfer data from MPU to ■ register, transfer the contents to ■ register, and then repeat the same timing operation again. ■ Store the third transfer data from MmU in the register by timing operation.

After this, the SPUI will change the data as shown in Figure 62.
Moving on to the flow, a so-called zero erasure process is added to the three-digit contents of the ◎, ■, ■ register, and specifically, "0" data that does not need to be displayed is determined from each three-digit data. "F
” and convert it to “D・REG” with other data as is.
” to D2-DO. For example, if the contents of ■, ■, ■ are "000", convert them to "FFO", and convert them to "010".
”, convert it to “FIO”, and then convert it to “1”.
00", etc., it is transferred to "D.REG" as is. According to the flowchart in Figure 62, when the data of "FFF" is transferred, the SPUI changes the register contents to "0" and enters the "standby mode", but when other calendar number data is transferred, , ② Set the contents of the register to ``1'' to enter the ``display mode'', and display the contents of ``D.REG'' in segments on the calendar number display section 111 according to the ``display'' flow shown in FIG.

Specifically, first store "4" in the register for specifying the display digit, and then store "4" in the register to specify the address "D2".
Boat OH (04 to 07) on the condition that the contents of "D2" set and called based on "n" are not "F"
Immediately after, ◎ ``4'', which is the customer at the cash register, is output to Boat O.
Set to L (00-03) and by pre-programmed PLA, i.e. "4" → boat 02 = day, "2"
→Boat 01=Day, “1”→Boat 00=Day, “0”→
According to the PLA configuration without boat OL of daily output, drive the segment element SE2 of the upper digit, and select "D2".
Lights up to display the contents. Then, after the lighting display of the same element SE2 continues for about 200 French seconds, it disappears, and then ``2'' is stored in the register, and ``Dn'' is set so that ``DI'' is specified as an address. Then, the content of "01", which was called again in the same manner as described above, is displayed on the segment element SEI for about 200 French seconds.

Next, ■ store "1" in the register, set "Dn" so that "DO" is addressed, and then write the contents of "DO" called in the same manner as above to the segment element SE.
O! This will light up and display. If called “D2” ~ “
If the content of “DO” is “F”, the corresponding segment element SE is not driven, and for example, “D・REG
” is “FFO”, “0” is displayed only in SEO, and nothing is displayed in SE2 and SEI due to so-called zero erasure. In FIG. 61, SPU
During the control operation of the "display" as described above, I performs a timing operation to check whether the boat R13 is "L". After setting, set the built-in timer in the SPUI to 200 French seconds and start it, then check whether boat R13 is "L", and when the timer measures 200 French seconds, the timer is over (end).
The operation of checking whether the flag is set is repeated.

If the timer over flag is set first while the boat R13 remains at "H" without data transfer from the MPU, the control operation of the "display" described above is continued as is, and the contents of "D REG" are is continuously displayed on the almanac display unit 111, and while in the "display mode", the above-mentioned "display" control operation is repeated to display three-digit segments using a dynamic drive system. However, S.P.
If the boat R13 inputs the "L" signal indicating data transfer, the UI stops the "display" operation described above, immediately receives the transferred data from the MPU according to the timing flow shown in FIG. If the data is "present or absent", the control operation is executed based on this and the "display" operation is repeated again. However, for example, when new "calendar number (display) data" is transferred, the same procedure as above is performed. After performing the "data change" operation, the newly transferred data is displayed by lighting on the calendar number display section 111 in place of the segment contents that have been displayed up to that point. However, if "FFF" data is transferred as new "number data", follow the flow in Figure 62 to rewrite the register to "0" and change from "display mode" to "standby mode". , repeats only the timing operation of checking whether the boat R13 is "L", and continues to specifically wait for data transfer from the M-circle U. That is, when the number data of "FFF" is transferred from the MPU, the SPUI transfers the transferred data "FFF".
” is stored in the “D.REG” and the “display” operation is performed, since nothing is displayed on the calendar number display section 111, unnecessary control operations are omitted and the system enters the “standby mode”. , only perform timing check operations.

After that, if data valid as a calendar number display is transferred, it immediately goes into "display mode" and displays the same lighting display as above based on the transferred data, and also checks the timing from time to time. It also specifies data transfer from the MPU. In addition, "
"Calendar number (display) data" is stored in "D" in its internal RAM.
・The contents of each digit of "REG" are transferred from the upper digit D2 to DO in order, and SP
It matches the digit order of "D REG" for display on the UI.
The SPUI, which executes each of the above controls according to the main flow in FIG. When the flow is lowered, the CPU immediately exits from the main flow shown in FIG. 60, executes interrupt control according to the flow shown in FIG. 63, and then returns to the main flow. In the flow shown in Fig. 63, the SPUI saves Acc, Immediately returns to the main flow after register recovery as invalid, but for example, if the "V E02" signal is "H", boat R1
After setting port 03 to "L", port 03 is set to "H" to give an external interrupt command to the MPU. Then, after some time has passed until MenU confirms this, boat 0
3. Return R15 to their original values, recover the register, and return to the main flow. MPU shown in FIGS. 23 to 26,
As is clear from the timing of the external interrupt of the SPUI, the point in time when the SPUI gives the external interrupt to the MPU is when the carriages 13 and 20 are traveling to the left and the carriage center line C , D correspond to the central position between the striped needles 3, and a valid external interrupt command is given to the MPU from the SPUI each time.

That is, in this example, the needle pulse output related to the rope needle pitch of the carriage is executed by program control of the processor in place of a carriage position detection circuit consisting of a hardware logic circuit. will be explained according to the flow diagrams in FIGS. 58, 59, and 64 to 82. First, in FIG. 64,
SPU2 starts control from the program counter's "0" as the starting point by power-on reset, and first outputs "0" data to the parallel output P boat to set boats PO to P3 to "L".
” output, the pulse motor 80 can be stabilized in the initial stopped excitation state, and the error lamps L14 and LR
While keeping the lamp L17 off, the OL boat 0
Once all of 1 to 03 are output as “L”, the DC motor 86
In addition, necessary system flags and registers in the internal RAM are set to an initial reset state.

For example, store "0" in the ■register that represents the key step order described later, or store "Z REG" for calendar number data.
(Z2 to ZO) are cleared to "000", etc., and then "B" is stored in the key input permission flag ① register. As shown in the cash register details in Figure 47, the ■ cash register is
Depending on the content of each bit with a weight of 1↓“2”, “4↓8”, the ■0 bit with a weight of “1” will be changed from “0” to “
9" corresponds to the numeric key 1101, and the bit 1 with a weight of "2" corresponds to the step key 113, which also has a weight of "2".
■2 bit with a weight of 4 is the left and right key 114, 11
5, bit 3 with a weight of "8" is a step back key 116 represented by a function key, and a start key 1
17 and reshaping key 181, flag contents are stored in such a manner that when each bit is "1", key input is permitted, and when each bit is "0", key input is prohibited.
Then, the SPU 2 asks the mirror on which each of the above keys is operated for the contents of the key input permission flag (register), and if the key input is permitted, the key operation at that time is validated and control is performed based on this; (2) The correction key 112 always responds as a valid key operation regardless of the contents of the cash register. Therefore, at the initial stage of the power-on reset, the data "B" stored in the cash register is
key is disabled, and the other keys are enabled. In addition, since the SPU2 has a configuration in which each output port is automatically set to "H" by a power-on reset like the above-mentioned SPUI and MPU, there is no need to set the port 05 by a program command, and the electronic buzzer does not operate. It enters a waiting state.

Thereafter, the SPU 2 reversely rotates the DC motor 86 by setting the boat 01 to an "L" output, and moves the sensor 92 to the left position where it is waiting for a discussion. Even if there is, the boat returns to zero after the time required to return to the left position (200 seconds) has elapsed.
1 remains as an "H" output, and further sets the boat 02 to an "H" output in a reverse hold state.

That is, when the power is turned on, the sensor 92 always stops at the left reading special position in preparation for the subsequent discussion run. Next, SPU2 outputs "H" from boat R7 (already at "H" when the power is turned on), and the MPU can freely use that boat signal to indicate that SPU2 is in the "N○・BUSY" data transfer state. Once you are able to check it, ask about the contents of the NA cash register.

If the content of NA register is "1", error lamp L
14 is displayed blinking, but since "0" is initially stored as a system clear when the power is turned on, it becomes a "standby mode" and a timing check operation is performed. That is, the SPU 2 is in a relationship where start commands for various controls are transferred from the MPU as numerical data representing each. Specifically, when the MPU transfers data to the SPU 2 according to the timing flow shown in FIG. Data “1” represents “Card Send/Return”, data “2” represents “Card Negotiation”, data “3” represents “Key SW Scan”, and data “3” represents “Power-on Transfer”. After setting the data "6" in boats R12 to R15 in advance,
By setting the output to “L”, the SPU2 outputs the boat R.
8 is checked to determine whether this is an "L" signal transfer command. Then, the SPU2 repeats the operation of constantly checking the boat R8 in the "standby mode" and waiting for data transfer from the MPU.
If input is "L", the data transferred via boats R12 to R15 is immediately stored in the cash register, and boat 04 is input as "L".
'' output indicates the completion of the transfer.

When M-en U confirms the completion of this transfer with boat RIO and outputs data of "F" to boats R12 to R15, returns boat 03 to "H" again, SPU2
After returning to "H", the boat R7 is immediately set to "L" output of "BUSY" according to the main flow shown in FIG. 64, and control operation based on the transfer data is started. In other words, when the contents of the register (transfer data) is "6", this is used as a control start command for "power-on transfer", and then the data is transferred from the MPU according to the timing flow shown in FIG. 58, which is similar to the above. The data to be stored is transferred to the internal RA of SPU2.
Store it in the required register of M. That is, in this example, SP
U2 is in charge of the actual feed control operation of the power card 59, for example, depending on various needle selection modes, whether or not to execute the feed operation of the card 59 as the carriage reverses its travel; The SPU itself determines which direction to send the M
The PU is configured to give the SPU 2 a "carriage reversal signal" which is a command to start sending back the force card, and when reading the card 59, the sensor 92 outputs a "card data" signal of "oF"1". SPU2 judges whether the relationship between
However, since the SPU2 itself cannot protect the memory of these basic data (when the power is turned off), these basic data cannot be sent to the MP.
The MPU then stores it in the outboard AM. Therefore, when the power is turned on, the MPU always transfers basic data to the SPU 2, and subsequent control operations are performed based on the transferred data. In such "power vertical transfer", the data sent from the MmU includes the "DN/REG" for the number of external RAM stages (middle stage), the memory contents of the "first stage {2'" and "last stage '3}". First, the flag contents are the card feed direction, KRC, FWD, vertical multiplication, and PN, and the SPU2 stores these transfer data in the internal RAM as "number of stages/REG (DN)" and "day/REG" for the first stage. , "0 REG" for the final stage, ■ register for card feed direction flag, KF register for KRC flag, FF register for FWD flag, TF register for vertical information flag, P for PN flag
Store in F register.

After completing the "power-on transfer", the SPU2 outputs the "H" signal of "N○・BUSY" to the boat R7 again, then moves to the check operation of the boat R8, and waits for the next data transfer from the MPU. do. Further, when the SPU 2 receives data "2" from the MPU, it operates as a control start command for "card discussion" and performs control according to the "power-card discussion" flow shown in FIG.

That is, the SPU 2 first stores "0" in the card data transfer count register (2), sets a built-in timer to 200 seconds and starts it, and then asks for the contents of the (2) register for sensor movement direction. If the contents of the ■ register are "1" for backward movement (left), the boat 01 is outputted to "H" and the sensor 92 is moved backward, but for example, when the system clock IJ is turned on as when the power is turned on, If the initial "O" reset is stored as the A, the boat 00 is set to "H" output, the sensor 92 is moved to the right, and the "CLOCK" signal which is the input signal of the port RII is checked. .

As is clear from FIG. 34a, for example, immediately after the sensor 92 starts moving forward from the left reading position to the right, "1" corresponding to the "1" pixel area 61 on the card 59 is displayed. "C" of "L" until it reaches the left end of the number transparent window 73a.
LOCK” signal is output, SPU2
It is repeatedly checked whether the "CLOCK" signal is "H" until the number 2 reaches the transparent window 73a numbered "1".

In addition, when the sensor 92 starts to move back to the left from the right handgun position, the sensor 92 will continue to move until it reaches the right end of the transparent window 73a numbered "60" corresponding to the pixel area 61 numbered "60". Since the “L” “CLOCK” signal is output, SPU2
Repeat "C" until you reach the transparent window 73a numbered "0".
LOCK” signal is “H”. And S
At the same time, PU2 continues to check whether the timer over (end) flag is set, and if the "CLOCK" signal is "
If 200 seconds are counted and the timer over flag is set before the change to "H", the sesosa 92 has some kind of failure and has not started running, or the card 59 is not working properly. (Guide plywood 7)
2 is also formed with a reflective surface similar to the highly reflective coating of the guide plate 73, so the "CLOCK" signal is "L".
Immediately increment the ◎ register and transfer M Maruyama and "0" data. That is, S
In accordance with the timing flow shown in FIG. 59, PU2 stores in advance "1", which is being transferred, in the transfer flag ■ register, and then outputs the transfer data from the register to boats R12 to R15.
Port 04 is set to "L" output to notify the MPU of data transfer.

Then, the MPU responds to this, ends the data transfer, and outputs "L" from port 03, which causes the SPU to
2 confirms the data transfer, sets the register to "0" indicating no transfer, outputs data "F" to boats R12 to R15, and returns boat 04 to "H". In response to this, SPU2 confirms that MenU returns boat 03 to rH, and then SPU2 increments the ◎ register again and transfers the "0" data to MmU, repeating this process for a total of 15 times. Perform data transfer. As a result, even in the event of an argument error where the sensor 92 is out of order or the card 59 is not set, the "0" signal is substituted for the "card data" signal.
The data is transferred by M yen U'. According to the flowchart in FIG. 68, when there is no discussion error and the SPU2 detects an "H""CLOCK" signal before the timer measures 200 seconds, it then resets the serial empty flag. After that, turn on the serial input external clock, set the timer to 24 seconds, and start the timer.

Then, "
Repeating the operation of checking the empty flag that is set when four "L""CLOCK" signals are given and the operation of checking whether the timer over flag is set, and if the empty flag is set first,
At that time, the 4-bit "card data" signal stored in the serial buffer is input as is, based on the contents of the PF register for the PN flag, if it is a positive "0". Transfer the "card data" signal to the MPU, and if it is a negative (reverse) "1", reverse the contents of "1" and "0" in the serial buffer that stores the "card data" signal. For example, if the bit content is "0010", change it to data "1101" and transfer it to M yen U, and
After incrementing the contents of the register, set the timer to 2 again.
4 Set it on sand and repeat the same action. That is, a 60-bit "card data" signal corresponding to the 6-needle pixel area 61 is obtained by one scan of the forward or backward movement of the sensor 92, and this is treated as data of 4 bits each. Transfer to MPU in order. ``If the SPU2 stops due to some kind of failure while the sensor 92 is running, a timer flag of 24 seconds is set before the empty flag is set, so that the subsequent MP
The data transferred to U is represented by "0", so that a total of 15 data transfers are performed. The SPU 2, which operates according to the flowchart in FIG. After the elapsed time, the boat 00 remains at the "H" output, and the boat 02 is further set at the "H" output and held, but for example, if the sensor 92 moves back,
■Change the contents of the register to "0" for forward movement, and after 60 seconds have passed, leave boat 01 at "H" output, then set boat 02 to "H" output and hold it, and finally To,
At that time, the "card data" signal was transferred as is to the MP river during the card picking operation, or "0", "
1" is reversed, forward and reverse soldering is performed, and the contents of the PF register are transferred to M-en U in order to notify whether the data has been transferred, and the "card transaction" control is completed.

Then, SPU2 again sets boat R7 to “N○・BUSY”.
'', then enters the check operation of boat R8 and specifically waits for the next data transfer from the MPU. 6th
According to the main flow in Figure 4, SPU2 receives “
1" is transferred, this is used as a control start command for "card sending back" which is a carriage reversal signal, and control is performed according to the "card sending back" flow shown in FIG. 65.

That is, if the switch SW6 is initially set to the position without double rotation (KRC) and the switch SW7 is set to the position without vertical double, judging from the contents of the SW register, the SPU2 sets the pulse motor feed speed. CF for
After storing "9" in the register, next "day RE" for the first stage.
On the condition that the contents of "G" and the final stage "0・REG" are different, check whether the contents of "DN・REG" and "日・REG" are the same, and on the condition that they are, the card For feed direction flag ■ Store the normal feed data of “0” in the register and press “
After incrementing the contents of “DN・REG” and adding 1, the process moves to the “DN・Flag transfer” subroutine shown in FIG. 66, and the contents of “DN・REG” and
The contents of each flag in the F register are also transferred to the MPU. Then,
In order to perform one stage feeding operation of the card 59, the process moves to the "card feeding" subroutine shown in FIG.
Perform control at 80 pm. According to the flow in Figure 76, SP
U2 first sets the boat PO to "H", starts driving the pulse motor 80, resets the timer over flag, and then sends the data of "9", which is the passenger of CF, to TL and TH of the timer counter. Set (10 seconds when CF=9) and start the timer. That is, in the step control of the pulse motor 80, the SPU 2 uses a built-in timer to feed each step of the pulse motor 80 by changing the magnetic excitation pulse at 10 msec intervals, and moreover, the SPU 2 controls the pulse motor 80 by four steps for each -stage of the card 59. Specifically, after changing the "H" and "L" outputs of the required boats P0 and PI, the timer is set to 10 seconds and started. , and then starts checking the timer over flag. And SP
In U2, when the timer clocks 10 seconds and the timer over flag is set, then outputs the boat PI to "H", sets the timer to 10 seconds again, starts the timer, and clocks 10 seconds again. After the over flag is set, the boat PO is returned to the "L" output, the timer is set to 10 seconds, and then started, and after another 10 seconds, the boat PI is also set to the "L" output. Return, part 1
After 0w seconds, the process returns to the flow shown in FIG. 65. In Figure 40a,
Port P performed by the above “card feed” control
0, PI and each inversion signal output change pulse motor 80
Based on the force-feeding mechanism of the pulse motor 80, the card 59 moves one step in the direction of arrow G in FIG. will be advanced one step at a time.

After completing the "Card feeding" control according to the flowchart shown in FIG. 76, the SPU 2 then moves to the "PN set" subroutine shown in FIG.
The contents of the PF register, which is the basis of whether to leave the "card data" signal as it is, or reverse the "0" and "1", solder it forward and reverse, and then transfer it. Determine.

That is, according to the flowchart in FIG. 67, if the switch SW6 is not double soldering, it is simply related to the switch SW8, and if it is set to (KHC), a negative ( Otherwise, a positive (positive) “0” is stored to complete the PN set. After that, SPU2 again changed the boat R7 to “N○・BU”.
SY" is set to the "H" output, a check operation is performed on the boat R8, and the next data transfer from the MPU is awaited. Also, according to the flow in FIG. 65, the SPU2
If the contents of "G" and the contents of "日・REG" for the female stage are not equal, then check whether the contents of "DN・REG" and "0・REG" for the final stage are equal, and if they are not, If there is a forward feed "0" in the register, the same operation as above is performed, such as incrementing "DN・REG" and adding 1, but if there is a reverse feed "1" in the register, "DN・REG" is REG”
After decrementing and subtracting 1, "DN
- The process moves to the ``Flag Transfer'' subroutine, and after its execution, the process moves to the ``Card Return'' subroutine shown in FIG. That is, the SPU2 sets the boat PI to "H" for each low sand by using the built-in timer according to the flow in FIG.
The output, boat PO is set to "H" output, boat PI is set to "L" output, and boat PO is set to "L" output to form the excitation pulse change of the pulse motor 80 shown in FIG. 40b, thereby -step When 40 seconds have elapsed for a total of 4 steps, where 10 seconds have elapsed, the card 59 is moved back by one step in the direction opposite to the direction of arrow G in FIG.
Move to "PN set" in the figure. Also, Fig. 65 Flow
Accordingly, SPU2 selects “DN・REG” and “0” for the final stage.
・If the contents of "REG" are equal, then switch SW4
If they are set vertically, the contents of the register will be changed to "1" for reverse feed, and then the operation will move on to decrement "DN・REG". However, if switch SW4
If it is set repeatedly, the first stage ``Day・RE'' is set.
The contents of "G" are stored in "DN・REG", and the contents of "
After performing DN/flag transfer, transfer 0/RE for the final stage.
Calculate the difference in the number of steps between "G" and "日・REG" for the first step,
That is, the number of stages required to return the card 59 from the final stage to the female stage is determined and stored in "T.REG". And S.P.U.
2, in order to execute the T-stage return, move to the "T-stage card feed back" subroutine shown in Fig. 78, and in particular, by utilizing the ◎, ■, and ■ registers, the pulse motor is activated at the beginning of the return. Set "9" in the CF register for speed setting, and press 1
The excitation pulse is changed every 0 seconds, and the -step is 1.
One stage of card feeding back is executed after a total of 4 steps of 40 msec, which is 0 machine seconds, but the number of consecutive card feeding back steps is '
According to the contents of "T.REG", as shown in Fig. 95, the contents of the CF register are added sequentially to accelerate the excitation change of the pulse motor, and at the end of the return, the feed speed is the same as the beginning. In this way, the card 59 is sent forward or quickly returned to the table at once, and the electronic buzzer is made to chime during the sending back. Further, according to the flow shown in FIG. 65, the SPU2 is configured such that, for example, the switch SW6 is set to no double input (KRC), and the switch SW6 is set to no double input (KRC).
If W7 is set to vertical multiplication, at the beginning of the game, as the first vertical multiplication, check the TF register that stores "0" without card feeding, and if it is "1" with card feeding. For example, change this to "0", which means no feeding, and then execute the same feeding control operation as described above to send the card 59 back.If it is "0", which means no feeding, change it to "1", which means feeding.
Instead, only ``DN/flag transfer'' and ``PN set'' are performed, and card 59 is not sent back. That is,
Even if a "card sending back" start command, which is a carriage reversal signal, is given from the MPU, sending back the card 59 is stopped once every two times, and intermittent feeding for vertical doubling is executed. Also, according to the flow in Figure 65, SPU2
If the switch SW6 is set to double input (KRC), ask the contents of the FF register for the FWD flag, and if it is "0" with feed, set it to "1" with feed. ”, and furthermore, if the content of the KF register for the KRC flag is “1”, it is concremented to “0”, and if it is “0”, it is concatenated to “1”, and then the same feed control operation as above is executed to control the force. The code 59 is sent back, but if it is "1" indicating no sending, it is changed to "0" indicating sending, and only "DN/flag transfer" and "PN set" are performed.

In the "PN set" flow in FIG. 67, in the case of double input, the contents of the KF and FF registers are effectively used, and the contents of the PF register are also determined in relation to the set contents of switch SW8. Ru. Sometimes, in the flowchart of FIG. 65, the contents of "DN REG" match the number of stages of the pixel area 61 on the card 59 that the sensor 92 corresponds to at that time, and The start command is the relationship that is transferred when the carriage reverses its direction of travel.

Therefore, for example, as shown in FIG. 52, switch SW4 is set to "REPEAT",
65, the SPU 2 operates according to the flow shown in FIG.
The card 59 is advanced so that the number of pixel area stages on the top 9 is changed to "1" stage, "2" stage, "3" stage, etc. according to the number of traveling and reversing times of the carriage. ” row, move card 59 back in one step and play “1” again.
It is controlled so that it becomes a stage, then "2" stage, then "3" stage, and so on. However, if it is set to "vertical facing", the "1" stage, "2" stage, and "3" stage are set in the same way as above.
After progressing through the steps, the next step after the "30" step is card 59.
Move back one step to make it "29" step, then "28"
The control advances through stages, "27" stages, etc., returns to "1" stage again, and then repeats "2" stages, then "3" stages. Further, when the switch SW6 is set to "double folding", each of the above-mentioned stages changes by one stage each time the carriage reverses its travel twice, and in relation to each travel of the carriage, For example, "3" stage, "3" stage, "4" stage,
There are "4" stages, and as a result, each row of pixel areas 61 is scanned twice by the sensor 92.

The SPU 2, which performs control according to the flow shown in FIG.
By storing "0" in the register, "P" in FIG.
When forming a double amikomi according to the "N set" flow, a negative (reverse) "1" is placed in the PN register for the first time in relation to the "card sending back" start command from the MPU. is set, and the second time it becomes positive “0”
is set, the third time is "0", the fourth time is "1", the fifth time is "1", the sixth time is "0", the seventh time is "0", the eighth time is "1", and so on. Reverse ↓ “Correct”, “Correct”, “
It is regularly repeated in a reverse cycle.

Moreover, according to the flowchart in FIG. 65, the card 59 is sent one step at a time with two start commands from the MPU, so the signals on the same step on the card 59 are "correct" and "correct" respectively.
It is read twice: "Reverse". As a result, the card 59 for normal pattern knitting can be used for double knitting as shown in FIG. 94, so that the necessary needle selection operation can be carried out appropriately. At this time, if the vertical multiplication switch SW7 is set to vertical multiplication (furthermore, the feeding operation of the card 59 becomes intermittent, vertical multiplication can be performed freely even with double threading, and forward/reverse soldering is possible). However, if switch SW8 is set to forward/reverse soldering, the PN register is set in the opposite manner to the above,
First, it is ``normal'', then ``reverse'', then ``reverse'', ``normal'', ``normal'', ``reverse'', and it is possible to perform forward and reverse soldering even if there is a double thread. In addition, in the main flow shown in FIG. 64, when data "3" is transferred from the MPU, the SPU 2 uses this as a control start command for "key SW scan" and performs the "key SW scan" shown in FIGS. 69 to 72. perform an action.

That is, first, the process moves to the flow shown in FIG. 69, and the contents of the contacts of the various switches SW are checked, and the ON/OFF data is stored in the SW register of 3 words and 12 bits in total. In particular, when the contact contents of the pattern selection switches SW1 and SW5 are changed, "1" is stored in bit address 8 of the SW register to indicate that a change has been made, and the contact contents of the double layer switch SWO are also changed. Similarly, bit address 9
``1'' is stored in ``1'' indicating that switching has occurred, and the SW scan data, which is the contents of the SW register, is also transferred to M-yen U. That is,
Regarding the timing operation in FIG.
The scan data is transferred to the MPU, and then the switching position of the pattern selection switch 5 is checked from the contents of the SW register.

Then, SPU2 is "1 too" and ■ the contents of the register are any of "9" to "0", and "all too" and ■ the contents of the register are "6". ~ If it is one of "D", the step order is incompatible with the switching positions of the pattern selection switches SW1 and SW5, and in order to return to the step state of "0", please change the step order "0" to the cash register. Stored and used for flag with or without calendar number ◎ “0” with no number of layers
", then store "B" in the cash register, and store "Z・RE".
Clear "G" to "000".

Next, the SPU 2 checks whether a key is being operated according to the key scan flow shown in FIG.
9" number keys 110 at the same time and check whether all of the keys are OFF. If so, that is, if there is no key operation, then the boat R is turned on.
4 and set R3 to "L" output. And "3",
Scan the numeric key 110 for "8" and the correction key 112 at the same time, and if they are all OFF, then set the boat R2 to the "L" output, and press the numeric keys 1 to 10 for "2" and "7" and the step key. 113 and step return key 116 are scanned at the same time, and if they are all OFF, the "L" output of the boat RI will cause the "1" and "6" number keys 11 to be scanned.
0, the right key 115, and the reshaping key 18 at the same time, and if they are all OFF, the "L" output of the boat RO will cause the number keys 110 and left key 1 of "0" and "5" to be scanned.
14 and the start key 117 at the same time. If this is also all OFF, SPU2 will assume that no key was operated during the key scan at that time and
Store the FJ data in the ◎ cash register, transfer the M circle U' data using the same timing operation as above, and then transfer the 64th data again.
Return to the diagram flow and set boat R7 to “N01BUSY”.
After that, the same check operation for boat R8 as described above is repeated. SPU2 to M during key scan
The data to be transferred can be transferred using the numeric keys “0” to “9”.
Corresponding to "0" to "9", the step key is "A", the start key is "B", the correction key is "C", the left key and step return key are common "D", the right key and reshape key. The key is a common "E", and when there is no key, it is represented by "F". When the SPU 2 detects that at least one key key is not OFF in the above key scan, that is, when a key operation is detected, the SPU 2 selects the "L" set number of one of the boats RO to R4, which is the scan port number at that time. For example, when a key operation input is confirmed during scanning when boat R2 is outputted as "L", data of "2" is stored in the register.

Next, it is checked which key was operated, and if it is a key connected to boats K0, K1, and K2, the flow moves to the respective key control flow, but for example, if it is a key connected to boats KO and KI, If it is not a single key operation, such as when two keys are operated at the same time, transmit "F" data without a key to the MP river, and then check whether the key is turned OFF. Specifically, boat RO~R
5 are all set to "L" output, all key scans are performed at the same time, and it is checked whether the key contact contents inputted through the boats KO to K3 are all OFF, and this is checked repeatedly until this is satisfied. That is, when the SPU 2 confirms the key operation by key scanning, it executes the necessary control based on this, and then checks to see if the key has been turned off, and only when this is satisfied, returns to the flow in FIG. 64. By shifting to the operation of checking the boat R8 again, the key operation when two or more keys are operated at the same time is invalidated, or the same scan operation is performed twice or more by mistake due to the continuous operation of one key. I try not to repeat it.

In the “key scan” flow shown in FIG. 69,
Based on the above key scanning operation, when one of the numeric keys 110 from "0" to "4" is operated, the SPU 2 first asks for the contents of the bit 0 of the cash register and confirms that input of the numeric key 110 is permitted. If this is satisfied, it is asked whether the data of the most significant digit Z2 of "Z・REG" is "0".

In other words, check whether three-digit calendar number data has already been entered in "Z REG", and if it has not been entered yet, next Check whether the content of "Z・REG" is "000",
If not, or even if it is "000", after confirming that the new key input data is not "0", enter "Z.
Shift the contents of ``REG'' one digit at a time toward the upper digits, and write new key input data for the lowest digit Z 川こ■ register customer. Then, ■ store a flag indicating that there is a calendar number in the cash register, ■ store a "0" flag indicating that there is no outside display, and add the input permission state of the step key 113 to the contents of the cash register, and then By temporarily outputting "L", the monostable circuit 176 and the transistor 17
Function 7 makes the electronic buzzer BS ring out.
Thereafter, the SPU 2 transfers the key input data from the cash register to the MP river, and then inquires whether the key has been turned off and repeats the same control as described above.

SPU2 changes from “0” to “4” according to the flow shown in FIG.
When confirming the operation of number key 110, number key 11
The input of 0 is not allowed, and the input of “Z・REG
” is full of calendar number data for all three digits, or only in a state other than step “0”, “Z・REG” is “

If it is the numeric key 110, the key operation is regarded as invalid, the "F" data without a key is transferred to the MPU', and the key OFF command is started. In the state of step "0", in this example, when the number of unraveled rows of the knitted fabric for reshaping is counted, there is a possibility that "0" will be counted as the number of unraveled rows. If you have messed up the needle pattern and want to recreate the selected needle pattern, the calendar number data is

That is, in this example, when the carriage stops moving during knitting, it is preferable to remove the carriage before removing it, or at least remove the carriage and move it to the well-known auxiliary rails attached to the left and right ends of the needle bed or the same end. Later, left and right standards 38 again
, 40, the reshaping key 118 is always operated, and this allows the operator to make the system remember to remove the carriage. Then, start the game key 1.
17 will be temporarily disabled. In addition, SPU2 has a "0" in the NA register that indicates no carriage removal, and ◎ If there is a "0" in the register without a calendar number, this will prevent it from being pressed twice.
Check the contents of the cash register, and if there is a ``1'' indicating that it has already been operated, it will not respond to the operation of the start key 117, the electronic buzzer will not be emitted, and the keyless data will be sent to the MPU. Transfer "F". However, if there is "0" in the cash register indicating no operation, immediately execute the feed start control operation according to the flow shown in Fig. 71, and first store "0" data for normal feed in the register for the card feed direction flag. For female stage
At the same time, write the contents of ``日・REG'' to ``Number of steps REG (DN),'' and add ``1
The number of card feeding stages of the "T stage" calculated by adding "5" is stored in "T REG", and the process moves to the "T stage card feeding back" subroutine shown in Fig. 78 to feed the card of the "T stage". Execute. That is, when the start key 117 is operated, the card 59 always moves the set line 67 to the insertion section 14.
For example, in order to make the column of pixel area 61 of the "1" stage correspond to the reading position J (FIGS. 5 and 18), 16 stages are required. Since it is necessary to feed a card of It matches the reading position J corresponding to the sensor 92. Then,
After feeding the T-stage card, the SPU2 stores "1" indicating that there is an operation in the register, prepares to prevent the above-mentioned feed start control from being repeated more than once by mistake, and sends the FF register for the FWD flag and the KRC. Store the initial "1", "0", and "0" data in the flag KF register and vertical double flag TF register, respectively, and set the electronic buzzer BS to 8 islands.
``B'' data representing the starting key is transferred.

In addition, in response to the operation of the start key 117, the SPU 2 first performs the "Z check" of the "DN/Z check" subroutine shown in FIG. Shifting to the flow, and especially utilizing the calculation "L・REG", the inner customer layer number data of "Z・REG" is changed to the contents of "rH・REO" for the first stage and "0・REG" for the last stage. Check if the number is between them, and if it is an unsatisfactory calendar number error, store ``0'' in the cash register, turn on the error lamp L14, and turn on the electronic buzzer for 1 second. "F" data without the Men U' key is transferred, but if there is no calendar number error, then SPU2
asks for the contents of "Number of layers REG (DN)", and if there is data of "0" for card removal, it is obtained by adding "15" to the contents of "Z・REG" which is the number of layers data. "T
Perform force-do feed of "Dan" and store the contents of "Z・REG" in "Number of steps REG (DN)". After that, perform the initial setting of the flag similar to the above without calendar number, and

After storing the electronic buzzer and letting the Q Island sound, the MPU
Transfer "B" to.

Further, if the content of "number of rows REG (DN)" is other than "0" and the card has not been removed, that is, if the number of rows of the pixel area 61 of the reading position J corresponding to the sensor 92 is stored, then The content of “Z・REG” is “Number of stages REG (D
For example, if the content of "Z・REG" is larger than "Number of stages REG", the T stage that is the difference between them is sent back. Execute the card feed, and when vice versa, execute the card return of the T stage of the difference between them, and press "Z・REG"
In addition to storing the contents in the "stage number REG (DN)", the initial setting of each flag for the same aircraft is performed. As described above, the SPU 2 can: ■ When the register contents are step "0" and the start key 117 is operated effectively without a calendar number, the column of the first pixel area 61 matches the reading position J. If the card 59 is advanced in one step as shown in FIG.
The operation of the start key 117 is enabled to execute the start control by advancing or reversing the step, and only when the number of calendars has been exceeded.

Also, Fig. 71F.

Accordingly, the SPU 2 will: ■ When confirming that the step return key 1 to 16 is a valid operation based on the contents of the register, only when the NA register has "0" indicating that the carriage has not been removed, for example, ◎
There is "0" with no number of layers at the cash register, and "Number of layers REG (DN)"
” When there is no “0” to remove the card, store “0” in the “■” register to enable the starting key again, and
"T" calculated by adding "15" to the contents of "G(DN)"
Write the number of card return stages in "T REG" and use the "T stage card return" subroutine in Figure 78.
After returning the "T stage" card and making the electronic buzzer BS emit an E sound, "D" data representing the stage return key is transferred to the MPU. That is, when the step return key 116 is operated without the number of layers, the set line 67 of the card 59 is returned at once to a position that matches the upper green of the insertion section 140, contrary to the position at the beginning of the stack. This is a so-called set state where the card is removed. In addition, in response to the operation of the step return key 116, the SPU 2 responds to the following: ◎If there is a "1" with a calendar number in the cash register, first check the calendar number data of the customer in "Z REG", If the pupil number data is "000", perform the same 1-second electronic buzzer operation as described above, turn on the error lamp L14, etc., and send "F" data without a key to the MPU. For example, if the calendar number data is other than "000", then check the same "9XX" as above, and then remove the card by "0" from the contents of "Ran number RE○(DN)". If there is, add “Z・REG” to the contents.
15" is added and the card of the "T stage" calculated is returned, and if it is other than "0" and no card is removed, "Z
・Make the force match the number of stages that is the difference between “REG” and “Number REG”.
For example, if "Z・REG" is
If the number of stages is greater than "REG", the card is returned to the different "T" stage, and if the reverse is the case, the same card is fed to the "T" stage, and after each return, the card is returned to "Z REG".
Clear "G" to "000" and ◎ "0" with no number on the cash register.
'', and after making the electronic buzzer sound, the MPU
The "D" data representing the step return key 116 is transferred to.

That is, in response to the operation of the step return key 116, the SPU 2 functions as a key to return the card 59 to the card removed state if there is no layer number. When operated, this effectively functions as a key operation for aligning rows.

In particular, when aligning rows, the operator should use the sensor 9 at that time.
2 is a setting to calculate the number of rows of the pixel area 61 that corresponds to the reading position J (which can be grasped from the row instruction 63 corresponding to the observation position K), and the SPU 2 stores it in the "row number REG (DN)". The difference in the number of stages is corrected, and if necessary, the card 59 is sent back to ensure that the next control operation is accurate. With this, if you shift the card 59 at the wrong time, you can always throw the card 59,
Disturbances in control can be prevented. Figure 71 Flow 'Accordingly, the SPU 2 is operated by the ■Revisit key 118 from the contents of the cash register.
If it is confirmed that the operation is valid, first perform “D” in Figure 75.

That is, according to the main flow in FIG. 64, while in the "carriage removal" mode, the SPU 2 goes to the "error lamp blinking" flow in FIG. 81 only when the timer over flag is set approximately every 15 seconds. As a result, the error lamp L14 flashes at a one-second period as shown in FIG. 96. Also, according to the flowchart in Fig. 71, SPU2 has "1" with pupil number in the register,
If the reshaping key 118 is confirmed to be a valid operation, first store "0" indicating that the carriage has not been removed in the NA register after "9XX check" similar to the above, and then "Error" shown in Fig. 80. Shift to the “stop lamp blinking” flow.

When the left and right keys 114 and 115 are operated as in C and "D", the LR lamp L17 is turned on again to enable key-in again and to reset the calendar number.

In response to the operation of the step key 113, the SPU 2, which proceeds with the control according to the scan flows shown in FIGS. 69 to 72, responds to the operation of the step key 113, especially when the cash register shows "11" with the number of layers or "0" without the number of layers. However, ■ If there is a "1" displayed on the cash register, it will move to the step state in which the cash register is incremented and 1 is added. Change it to

is not functioning effectively. Also, regarding the left and right keys 114 and 115, the contents of the register are "6↓"7
”, “8”, “B”, “C”, and “D”, and ◎It functions effectively only when “0” with no number of layers is stored in the cash register, and the step return key 116 , starting key 11
7 and the reshaping key 118 are designed to function effectively only when the register contents are ``0''. The SPU 2, which carries out each of the above-mentioned controls according to the flowcharts of FIGS. 64 to 81, immediately controls the main Exiting from the flow, interrupt control is executed according to the flow in FIG. 82, and while the MPU is making port 04 an "L" output, the ports R12 to R15 forming the data bus line are being made "F" data output, and the MP
The bus line is opened so that U can use it freely, thereby making it possible to transfer data from the MPU to the SPUI even during data transfer from the SPU 2 to the MPU. Then, in SPU2, MPU sets boat 04 to "H".
When the data is returned to output, if there is a "1" in the register indicating that the data has been transferred, that is, if the data is being transferred according to the timing operation shown in FIG. Output to R15 and return to the main flow after register recovery. Next, the control operation of the MPU will be explained according to the flowcharts shown in FIGS. 83 to 93. First, in FIG. At the beginning, the boats 00 and 01 are set to "L" output, the left indicator lamp L15 and the right indicator lamp L16 remain off, and the required system flags are entered in the "flag register" of the internal RAM. Things (Y address 4-7)
is the initial "0" reset content, and furthermore, the step memo of the outer ship AM is "Onnadai stage (2) ↓ "Final stage {3''', "Mosho A ■", "Mosho A {5}" , ``Moto left B■↓``Moto right B■
” Data “0” is written in the address portion for distinguishing left and right of the memo (addresses from AO to 7→D).

Next, the MPU reads the contents of the "flag memo" in the external RAM and transfers them to the address part (Y address 0 to 3) of the "flag register" in the internal RAM, and then writes "6" to the SPU2.
” data and performs a “power-on transfer”, and saves the memory contents of the stage number (middle stage) “DN/REG”, “Onnadai stage ■” and “last stage '3}” in the external RAM. As a result, the flag contents of a part of the "flag register" in the internal RAM, such as card feeding direction, KRC, FWD, vertical multiplication, and PN, are transferred to the SPU 2 according to the timing operation shown in FIG.

After that, the MPU stores the step status STEP・N
The initial data “0” is stored in the O cash register (hereinafter referred to as the SN cash register).
”, outputs “0” data that matches the contents of the SN register to the parallel output port P, and lights up the OK lamp LO by the action of the decoder circuit 172.
Store "1" in the power-on flag, set it to the external interrupt enabled state, and when an "L" interrupt command is input to the IR number terminal, immediately shift to the flowchart in Figure 91 to control the interrupt. to a state where it can be executed. Furthermore, when the power is turned on,
The configuration is such that the OK lamp LO is always lit, and since the hatch 120 is made of a transparent or semi-transparent material, even if the hatch 120 is closed, the lighting of the OK lamp LO can be confirmed from the outside. It can also be used as a so-called power pilot lamp. The MPU, which has completed the power-on control as described above, transfers data "3" to the SPU2 to execute the "key SW scan" operation according to the flowchart in FIG.
The operation of receiving "SW data" and "key-in data" transferred from PU2 and executing various key scan controls in response to the transferred data, and the contents of "flag register" in internal RAM (Y address 0 to 3) of the external RAM.
The operation of writing to "flag memo", as well as starting the thread, reshaping, data change (DC), forced read (CR),
The operation of checking whether the content of each flag of the data set (DS) is "1" is repeatedly performed as the main routine.

In particular, before the SPU2 executes the key scan operation, the SPU2 inputs the signal applied to the serial input terminal SI in synchronization with the internal clock.
"N○・BU" that can accept data transfer from
Check whether it is in the "SY" state or not, and if it is "BUSY", check the C, CR, and DS flags above, move the contents of the "Flag Register" to the "Flag Memo", Furthermore, only the operation of checking whether SPU2 is "BUSY" is repeated. First, the details of the key scan control will be explained according to the flowcharts in FIGS. 84 to 88. The MPU stores the "SW data" transferred from the SPU2 in the SW register of the internal RAM, and also stores the "key scan data" in the key register. and execute various key scan controls based on each data.

For example, Fig. 84F. According to 1, when "F" data without a key is transferred from SPU 2, it is checked from the contents of the SW register whether pattern selection switches SW1 and SW 5 are all set to the same position. When it is set to , the key scan control shown in FIG. 84 is immediately terminated. However, when it is set to 1, then it is checked whether the step status of the SN register is greater than "8", and if not, the key scan control is terminated. If so, assuming that 1 is also an incompatible step content, change the contents of the SN register to "
0” step and OK lamp L that matches the contents.
O is lit, the calendar number flag is reset to "0" with no calendar number, the display flag is reset to "0" with no display, and "Misaki FF" data is set in "D・REG" (D3 to DO). is stored, and the contents of "D'REG" (D2 to DO) are transferred to the SPUI according to the timing operation shown in FIG. ), the left and right display lamps L15 and L16 that match the contents of D3 are checked for lighting, and specifically, if the left data is "1" in D3, the boat 00 is outputted as "H" and the left Turn on the display lamp L15, and if D3 has the right data "2", output 01 to "H", light the right display lamp L16, and set D3 to "0".
If there is data, leave both boats 00 and 01 with "L" output and both lamps L15 and L16 off.
End key scan control. Also, Fig. 84F.

According to 1, if all modes are selected without a key, it is determined from the contents of bit "8" of the SW register whether the switch has been changed to all modes in the key scan at that time, and whether there is a change. If there is "1" in the SN register and the step content of the SN register is greater than "5", it is assumed that the step status is completely unsuitable, so set the calculation flag to "1" with calculation in advance. , executes the return operation to the "0" step state similar to the case of 1 above, and then shifts to the calculation flow for the reference position of all models based on the "1" content of the calculation flag. That is, in this example,
If all the notes are selected, the data corresponding to each memo of "first stage", "last stage", "model left A", and "model right A" will be input even if the operator does not specifically specify it. By doing this, the reference position and needle selection are adjusted so that the center of the information effective width (pattern width) of pattern A coincides with the center of the needle bed, and a repeated knitting pattern is realized over all the needles on the needle bed. The MPU automatically calculates the range and writes it in the "Key A", "Select Left A", and "Key Right A" notes. According to the calculation flow in Figure 84,
The MPU first resets the calculation flag to "0", then calls the contents of each memo of "Makusa A [4'↓"MoR A {5}]" and writes "E'・REG" and "D'・REG” and
The pattern width W data obtained by adding 1 to the difference between them, for example, if there is a horizontal double, write it as it is in the "base A (6}" memo as the reference position of the left W number, and also without the horizontal double). If so, the x data obtained by dividing the pattern width W data into two equal parts (W/2=x) cannot be divided into two equal parts (W/2=x...1)
Then, write the smaller x date in the "base A (6)" memo as the reference position for left x number.

That is, as illustrated in FIG. 97, if "Momo A" with a width that cannot be divided into two equal parts is selected, the setting is such that the center reference is always the number 1 knitting needle on the right side, and the number 55 knitting needle is always the center reference. As shown in the figure, even if there is a double needle, the reference position is determined so that the center of the double double "A" matches the center of the needle bed. After that, the MPU writes the data of the left 10 knitting needles in the memo to "selection left A {7}" so that all 200 knitting needles 3 on the needle bed can be selected as the needle selection range of all the needles, and After writing the data of the right 10th crab in the "Selection A ■" memo, return the step content of the SN register to "0", and
The contents of "T.REG" are restored to "0.REG" and the key scan control at that time is ended. Also, according to the flowchart in FIG. 84, all MPUs are newly switched, and the step contents of the SN register are "1" to "
5", the scan control is immediately terminated, but if the step content is "0", the pupil number data that is the content of "〇・REG" is saved to "T・REG". After that, the flow shifts to the same reference position calculation flow as described above.

Furthermore, when all is selected according to the flowchart in Figure 84, the MPU reads the bit "
8" has a "0" without pattern selection switching, and the bit "
If there is a "1" in "9" indicating that the chocolate double switch SWO is switched, that is, when the switch is newly changed to double chocolate,
In the same manner as when all options are newly selected, the operation moves to checking the step contents of the SN register. Furthermore, according to the flowchart in FIG. 84, when all modes are selected, the MPU sets this to "1" at power-on based on the contents of the power-on flag, even if there is no switch to double double mode. If there is, the process shifts to the same reference position calculation flow as described above, thereby ensuring that all reference position calculations are executed the first time the power is turned on. According to the flowchart in FIG.
The PU first executes various control operations based on the key-in data, and then shifts to the flow shown in FIG. 84.

For example, if the key data of "0" to "9" corresponding to the number keys 110 of "0" to "9" is transferred, first ask the number of tatami flags according to the flow shown in Figure 86. , If there is "0" without a calendar number, replace it with "1" with a calendar number, clear "〇・REG" to "000", and then set the key index number "0" to "9" at that time. ”, write “a” in the 1st digit DOI, “〇・RE
The content of "G" is set as "0board", this is transferred to the SPUI, and "a" is displayed in segments on the calendar number display section 111 under the display control of the SPUI. Then the 8th
Moving to point 1 in the flowchart of FIG. 4, the key scan control is completed by performing the same operation based on the contents of the SW register as described above. However, if the calendar number flag is "1" with a calendar number, it is assumed that the eyebrow number data is already stored in "〇・REG", and by shifting this up, the contents of DI are transferred to D2, and the content of DO is After moving the contents to DI, write the key data at that time to D Kawako, and then write "〇・REG"
” is transferred to the SPUI and displayed on the calendar number display section 111. Also, when keyin data "A" is transferred according to the flow in Figure 85, the MPU uses this as a representative step key and moves to the flow in Figure 86, and sets "0" to the calendar number flag and display flag. ” and
Moreover, if the SN register has step content "0" or "1", the SN register is incremented and 1 is added to set the step state to "1" or "2", and the subsequent contents of the SN register are Matching lamp LI or L2
' is displayed and the scan control at that time is ended.

However, if both the number and display are blank and the step content of the SN register is one of "2" to "D", the step content is treated as it is without incrementing the content of the SN register. , change the display flag to "1" with display, and change the contents of the step memo that matches the contents of the SN register, for example, if the step content is "2", change the contents of the "Onnadaidan ■" memo, and if it is "5", change the contents of the memo "Mosho B {5}"
Recall the contents of the memo, write it in "D・REO", transfer the contents of D2 to DO, which is "〇・REG", to the SPUI and display it on the calendar number display section 111, and check the contents of D3. , if it is "1", the left display lamp L15 is set to "2".
”, the right display lamp L16 is turned on and the scan control at that time is ended. Also, according to the flowchart in Fig. 86, when the MPU has a ``1'' in the numeric flag, the contents of the SN register are ``2↓``4↓``6↓``7'', ``9'',
When it is either "B" or "C", "D.R.
At the same time as transferring the contents of "EG" to "E・REG",
Also write in the step memo that matches the contents of the cash register, for example, if the step content is ``2'', write ``4'' in the ``start stage '2}'' memo.
”, then write it in the memo “Bokuza A'4}”. However, S
If the content of the N register is "3", "5", or "A", the inner customer "E'・REG" of the step memo before that step and its "〇・REG" ”, and if “〇・REG” is larger, leave it as is, but if it is 4・lower, write the contents of “D′・REG” in the step memo before the -step, and set “8・REG”.・REG
” in the step memo that matches the step at that time. For example, when the step content of the SN register is "3", before writing the calendar number data that is the content of "D'REG" at that time to the "final stage system" memo, the writing data is Check if it is larger than the contents of the memo '2', and if it is not, correct it by assuming that the first and last stages were keyed in in the opposite order, and press '〇・REG'.
Write the contents of ``Shidan {2}'' memo, and write the contents of the previous ``Onnadaidan ■
” Write the contents of “E′・REG” that match the contents of the memo to “last stage {3′”.

Similarly, when the step content is "5",
[5}" and "Mosho A'4'" memo, and make corrections if necessary. In step content "A", target "Shinyu B Kyou" and "Mosho B side" memo. Make corrections if necessary. Also, if the content of the SN register is either "8" or "D", "E・REG" which is the customer in the step memo before that step and "D・REG" at that time.
By comparing the contents of , and especially referring to the left and right data of E3 and D3, if "D REG" is the needle number data located on the right side on the needle bed, it will be left unchanged.
If the needle number data is located on the left side, “D・RE”
Write the contents of ``G'' in the step memo before the step, and ``
Write the contents of "E・REG" in the step memo corresponding to the step at that time. For example, when the step content of the SN register is "8", before writing the left/right distinction of "D REG" and the calendar number data in the "Selection A {8}" memo, Check whether the written data is a needle number located on the right side of the needle bed from the contents of the "Selection Left A [7}" memo, and if not, reverse the order at the left and right ends of the needle selection range. Correct it as if it was keyed in,
Write the contents of "D・REG" in the "Selection Left A's" memo, and write the "Z・REG" that matches the contents of the previous "Selection Left A'7}" memo.
” in “Selection A■”. Similarly, when the step content is "D", "Mitsubishi right B■" and "left selection B'
C}' corrections are made if necessary for the memo. Next, the MPU moves to ■6 locations according to the flowchart in Figure 86, so that all information is displayed and the contents of the SN register are "
5", move to point 2 of the flow in Figure 84, set the calculation flag to "1", and then perform the same return operation to the "0" step state as above. For example, if one of the left and right lamps L15 and L16 is on, it is turned off and the display on the calendar number display section 111 is also made to disappear, and then the process proceeds to the same reference position calculation flow as described above. .

Also, if 1 is also the same and the SN register contents are "8", or 2 is also the same and the SN register contents are "D".
”, move to point 3 in the flowchart in Figure 84, perform the same return operation to the “0” step state as above, and adjust the scan control at that time without particularly calculating the reference position. end. However, if you move to point 6 in the flowchart in Figure 86 and do not need to return to the "0" step, you can move to the next step state by incrementing the contents of the SN register and adding 1. Step lamp L that matches the contents of the SN register after addition.
lights up, sets the calendar number and display flag to "0", and stores "OFF" in "D REG".
Transfer the “FFF” data of 〇・REG” to SPUI,
Erase the display of calendar number display 11 1, and turn on the left and right lamps L1.
If either 5 or 16 is lit, turn it off,
The scan control at that time ends. Further, according to the flowchart of FIG. 86, if the display flag is "1" without a calendar number, that is, if the contents of the step memo have already been called and displayed on the calendar number display section 111, ■ After performing the same control as with the calendar number up to 6 locations,
Next, if it is unnecessary to return to the "0" step state, the content of the SN register is incremented and added by 1 to the step state without specifically erasing the display on the calendar number display section 111, and the result after the addition is At the same time as lighting up the step lamp L that matches the content, call up the content of the step memo that also matches the step content of the SN register, and select "D.

left and right lamps L15 that have been transferred to and responded to the contents of D3.
, 16 are turned on as necessary.

As a result, the content of the new step memo is called up instead of displaying the previous step memo, and the calendar number display section 1
11, and the scanning operation at that time is completed. In addition, when key-in data "B" is transferred from SPU2 according to the flow in Figure 85, M-en U assumes that this represents the starting key and moves to the flow in Figure 87, and if there is no calendar number flag. If it is "1", set the stock start flag to "1" and prepare to execute the required stock start control according to the main flow of Fig. 83, and reset the P check flag to "0". Set the data change pause flag (DHP flag) to "1" with pause, and then proceed to ■1 in the flowchart in Figure 84.
By moving to the location, a scanning operation similar to the above is performed. However, if there is a numeric value, in addition to the above operation, the calendar number and display flag are set to "0" (without), and "
Store “Misaki FF” in “D・REG” and “〇・REG”
Transfer the content "FFF" to the SPUI, erase the display on the calendar number display section 111, and turn on the left and right lamps L1 if necessary.
After turning off the lights at 5 and 16, the process moves to point 1 in the flowchart of FIG. 84. In addition, the MPU also uses “C”, which represents the correction key.
” data is transferred, follow the flowchart in Figure 87. If there is a calendar number, reset the calendar number and display flag to “0” (without it), and set “D・REG” to “0”.

FF" to the SPUI, the display on the calendar number display section 111 disappears, and if necessary, after turning off the left and right lamps L15 and 16, the process moves to point 1 in the flowchart of FIG. 84.

However, if there is no calendar number, the carriage removal flag (2
The same control as with the above-mentioned calendar number is performed by adding an operation of resetting the bit (consisting of bits) to "00" without deletion. Also, according to the flowchart in FIG. 85, if the key-in data "D" is transferred from the SPU2, the MPU
If the step status is not "0" from the contents of the register, assume that this represents the left key, and follow the flow in Figure 87.
First, store “Value FF” in “D・REG”, then D
Write "1" as the left data in D3, transfer "FFF" as the internal customer of "〇・REG" to SPUI, erase the display on the calendar number display section 111, and based on the content "1" of D3 to turn on the left indicator lamp L15, and then
Move to point ■1 in the flowchart in Figure 4. However, when the contents of the SN register are step status "0" and "D" is data representing the step return key, if there is a calendar number, the calendar number and display flag are changed to "without". 0", stores "price FF" in "D・REO", transfers "FFF" which is the internal customer of "D'・REG" to SPUI, and displays the calendar number display part 111. After turning off the left and right lamps L15 and L16 if necessary, the process moves to point 1 in the flowchart of FIG. 84. If there is no layer number, it is assumed that the card 59 is in a card removed state with the set line aligned with the upper green edge of the insertion section 140, and the external RAM is
After setting "DN/REG" to "000", the process immediately moves to point 1 of the flow in FIG. 84. In addition, when the key-in data "E" is transferred from the SPU 2 according to the flowchart shown in FIG. 85, the MPU assumes that this represents the right key if the step state is not "0" from the contents of the SN register, and selects the key-in data "E" as shown in FIG. Follow the flow and start with “D・RE”
After storing "Misaki FF" in "G", write "2" which is the right data in D3, and "FFF" which is the content of "〇・REG".
is transferred to the SPUI, the display on the numeral display section 111 disappears, and the right display lamp L16 is turned on based on the content of D3 "2", and then
Move to location.

However, if the content of the SN register is step status "0", and "E" is data representing the reset key, and if there is no calendar number, the initial data with removal in the carriage removal flag "11" is written as "11", and then the process moves to point 1 in the flowchart shown in FIG. 84. If there is a calendar number, move to the flow in Figure 88 to execute rework control, and then move to point 1 in the flow in Figure 84 or point 8 in the flow in Figure 87. , the details of which will be described later. By the way, the images shown in FIGS. 83 to 87.

The scanning operation that the MPU executes according to the above-mentioned SP
To explain the key input control in which the UI and SPU2 move sideways with reference to FIG. 19, first, the power switch 123 is turned on.
As this occurs, the OK lamp LO lights up, but nothing is displayed on the calendar number display section 111. In this "0" step state, the input data that is input as a calendar number using the numerical key 110' and displayed as a calendar number on the calendar number display section 111 in response to the input data is a start stage other than the first stage at the beginning of a row, rework data, or a stage. Effectively used as alignment data, the subsequent stitch start key 117, stitch correction key 118, step return key 1
In response to the 16 operations, various control operations are executed based on the respective keys. Calendar number display section 111 with "0" step
In the state where the calendar number data is displayed including "0", there is no change in the display even if the step key 113 is operated, and the Yoshiko buzzer Shigeru does not turn on Hibiki Marushima. It is determined that there is. In this state, step key 1
13, all you have to do is operate the correction key 112, and as a result the number display disappears and the number of layers is changed to "
0" step state. In the "0" step state with no calendar number, for example, if the card 59 is set so that the set line 67 matches the upper green of the insertion section 140 and the play start key 117 is operated, the "start stage (2 }”
Pixel area 6 on the card selected based on the content of the memo
The above-mentioned feed start control is executed such that the card 59 is fed in stages so that the first row (first stage) matches the reading position J of the sensor 92.

Also, in the "0" step state without calendar number, step return key 1
16 is operated, the setting line 67 of the card 59 is returned to the initial setting position corresponding to the upper edge of the insertion portion 140, contrary to the play start key, and so-called card removal is executed. In the "01 step state with the number of layers, if the start key 117 is operated after the card is set,
At that time, the row of pixel areas 61 of the row corresponding to the date displayed on the calendar number display section 111 corresponds to the take-off position J, and the starting control such as the step feeding of the card 59 is performed. executed.

Similarly, in the "0" step state with the calendar number, for example, if the step return key 116 is operated after the number of steps in the pixel area 61 corresponding to the reading position J is operated at that time, "
DN・REG” (same as the contents of “Number of layers REG (DN)” of SPU2), if the layer number data is different, “DN・REG”
The card 59 is sent back and row alignment control is executed so that the row of pixel areas 61 of the row that matches the contents corresponds to the reading position J. In addition, in the "0" step state without a calendar number, for example, when the carriage stops moving during knitting and is removed, if the reshaping key 118 is operated, the eff lamp L14 will blink, and in this state with the carriage removed, the number Only the key 110 and the correction key 112 are valid, and the other keys are invalid.

In the "0" step state with no calendar number, press the start key 117
, the step return key 116, and the reshape key 118 are operated more than once, they function effectively only the first time, and have no effect after the second time. Each time the key functions, an electronic buzzer sounds to let you know whether the key has functioned effectively or not. In addition, when the step key 113 is operated in the "0" step state with no calendar number, "1"
'' The step state is entered, the lamp LI lights up to indicate the selection timing of the pattern selection switches SW1 and SW5, and only the step key 113 and correction key 112 are enabled.

Next, when the step key 113 is operated, the "2" step state with no number is entered, the lamp L2 lights up, and the "2" step state is entered.
The data input corresponding to the first stage of "Momo A" is called.

Therefore, when desired starting stage data is input using the numeric keys 110, the input data is sequentially shifted up with each key operation and displayed on the numeral display section 111, and a "2" step state with calendar number is entered. . The left and right keys 114 and 115 have no function. If you make a mistake in operating the numeric key 110, the display on the calendar number display section 111 disappears by operating the correction key 112, and the display enters a "2" step state without a calendar number.
Step return key 1 from "1" to "D" step status
16. The start key 117 and the reset key 118 are disabled, and even if these keys are operated, they do not function at all. In the "2" step state without calendar number, press step key 11
When step 3 is operated, the contents of the step memo "first step ■" in the external RAM are called up and displayed on the calendar number display section 111 in the step state, and the step state becomes "2" with display. In this step state with the display, if you want to change the start stage data, you can input the desired data using the numeric keys 110, and at the same time the call display data disappears and the calendar number input data is transferred to the calendar number display section 110. will be displayed, and will be in a "2" step state with a calendar number. When the step key 113 is operated in the "2" step state with the number of layers, the number of layers display section 111 at that time
The data displayed in is written to the corresponding step memo "Start stage '2}" and the lamp L is

Also, in the "2" step state with the display, step key 1
13 is operated, the data currently displayed on the number display section 111 is rewritten to the corresponding step memo "Start stage ■" memo, and the lamp L3 is turned on.
lights up and the contents of the "start leg" memo are called up and displayed on the layer number display section 111, and the step enters the "3" step state with display. In the step state "3", when the step key 113 is operated after the layer number data is input using the numeric keys 110 by the same operation as above, the input data is changed to "
``First step glue'' is written in the memo, then the lamp L4 lights up, the display on the calendar number display section 111 disappears, and ``4'' without a calendar number is written.
It becomes a step state.

In response to this, when the numeric key 110 is operated and the step key 113 is also operated, the input data is written to the "Mosa A'4)" memo, the lamp L5 is lit, and the calendar The display on the number display section 111 disappears, and “No layer number” is displayed.

10 and step key 113 are operated, the input data is written in the "Model A {5}" memo. In the operation of the step key 113 at this time, the step state changes depending on which position the pattern selection switches SW1 and SW5 are set. Since it is the last input of the calendar number that should be counted as "zen moyo",
To notify this, the OK lamp LO lights up, and furthermore, the display on the calendar number display section I11 disappears, and the display with no calendar number is "0".
” Return to step state. At this time, step return key 11 is pressed again.
6, the thread start key 117, and the thread rework key 118 become effective. If the error lamp L14 lights up when the step key 113 is operated and the electronic buzzer emits a beeping sound, the calendar number data displayed on the layer number display section 111 at that time is determined to be excessive, and when the error lamp L14 lights up, the correction key 112
only is enabled, other keys do not function at all.

Therefore, the correction key 112 has no choice but to be operated, and in response, the numeric keys 110 and step keys 113 are enabled, and the display on the calendar number display section 111 disappears, returning to the step state without calendar numbers. , it is possible to input new calendar number data. In addition, when the lamp L5 is lit and the input data is displayed on the calendar number display section 111 in the step state of "5" with the number of layers, the pattern selection switch S
W1 and 5 are set to "1 too", and
When the step key 113 is operated, the lamp L6 lights up, furthermore the lamp Lh7 lights up, and the left/right key 114 is turned on.
, 115 is called, the display on the calendar number display section 111 disappears, and the state becomes "6" step state without a calendar number.

At this time, since the input data corresponding to the lamp L6 includes left and right data, the numeric keys 110 are temporarily disabled. Therefore, when either the left or right key 114 or 115 is first operated based on the data to be newly inputted, that is, the pattern reference position data, for example, if the left key 114 is operated, the left lamp L15 lights up. When it lights up and the right key 115 is operated, the right lamp L1
6 is lit. At this time, since the numeric key 110 must be operated next, the step key 113 and the left and right keys 114 and 115 are temporarily disabled. Therefore, the next desired needle number data is displayed on the numeric key 11.
When 0 is input and the step key 113 is operated after that, the new left/right discrimination data and needle number data are
"Group A (6}" is written in the memo, and the lamp L7 lights up in the same way as above, and the step state becomes "7".If you make a mistake in operating the left and right keys 114, 115, or if the needle number data If you make a mistake in the evening, press correction key 112.
With this operation, the left and right keys 114 and 115 become valid again, so you can freely start over. Lamp L7 lights up and “
In the step state of "7" where the data to be input into the "Selection Left A {7}" memo is called, press either the left or right keys 114, 115 or the numeric key 110 based on the data of the desired needle selection range. is operated and then the step key 113 is operated, the pupil number display section 11 at that time
The data (needle number) displayed in 1 and the left/right discrimination data by lamp lighting are written in the "Select left A'7}" memo, then lamp L8 lights up, and then lamp L17 lights up. The state becomes "8" step state.

Thereafter, in the same manner as above, when the step key 113 is operated after inputting the required data based on the call display in which the lamp L8 lights up, memory writing and OK are executed in response.
The lamp LO lights up, returns to the "0" step state, and "
The end of the data input to be counterfeited is announced as "1 too".

Further, when the lamp L8 is lit and the step key 113 is operated with a calendar number for memory writing,
If it is set to "2 too", then "
In order to input the data for "Momo B", the lamp L9 lights up, and it is announced that the data is to be input to the "Mosho B {9}" memo.
Therefore, after the same operation as described above is repeated and the required data is input, it is finally determined based on the call display that the lamp L13 lights up that the number of pupils is for writing into the memory and that the step key 113 is operated. , respond to this and OK
The lamp LO lights up, returns to the "0" step state, and "
The end of the data input to be counted is announced as ``2 more''. In each step state, the corresponding lamps L2 to L13 are lit, and there is no display in the layer number display section 111, and the left and right lamps L15 and 16 are off. If the step key 113 is operated while the step key 113 remains in the step state without the number of layers without any calendar number operation, the step state remains as it is, the content of the step memo that matches this is called up, and the layer number display section 111 is displayed, and if necessary, the left and right lamps L1
5, L16 lights up and enters the step state with display.

If the step key 113 is further operated while the display is still displayed, the step immediately advances to the next step state, and the contents of the step memo are called up and displayed in the same manner. Therefore,
By continuously operating the step key 113 with the display displayed, you can select "Onnadaidan (2)" which is the inner guest of each step memo.
- You can call up the required memo data of "Selection B (D)" and check it at any time. Moreover, if you want to change some data during the call display, enter new data in the step state of the required data display, and operate the step key 113 with the calendar number. It is also possible to make changes to the data. Sometimes, in each of the above step states, it is free to switch the pattern selection switches SW1 and SW5 while inputting new layer number data or while the data is being called and displayed. If the step state becomes unnecessary, the step state is immediately returned to "0" and the end of data input is announced.

Also, "Onnadai Dan" and "Doudan", "Mosa" and "Bokuu", "
The data entry order corresponding to ``Selection Left'' and ``Selection Right'' can be started from any point within those sets, and is automatically checked within the system and corrected if necessary to ensure accurate data is recorded in each step memo. written to. By the way, when the MPU operates according to the external interrupt flow shown in FIG. 91, when the carriage passes near the center of the needle bed, it changes the content of the center flag to "1" after passing the center, and then When the carriage reverses its running direction, and the content of the center flag is "1", the content of the center flag is "0" before passing.
'' and set the DC flag to ``1'' indicating that there is a data change, and the carriage further advances the counter-travel to find the first digit among the 200 knitting needles corresponding to ``200'' to ``399.'' When the knitting needle of "0" or "5" is passed for the first time, the CR flag is set to "1" indicating that the force reading has been performed.

Therefore, the MPU returns to the main flow in FIG.
For example, when the carriage is reversed, the contents of the DC flag are inquired, and if it is ``1'' indicating that there is a data change, the ``data change'' control is immediately executed. That is, the 200-bit contents of the "data set memo" in the external RAM are transferred to the "data change memo" as is, with each bit address matching, and for example, the contents of bit address "200" of the "data set memo" are transferred to the "data change memo". Memo”
The data is transferred to the bit address "200", and the same bit address is "201".
” to “201”, “202” to “202”, and so on, and finally transfer the contents of bit address “399” of “Data Set Memo” to bit address “399” of “Data Change Memo”. ”. Next, after changing the DC flag to "0" indicating no data change, "1" data is transferred to SPU2 to execute "card sending back" control, and based on this, SUP
The cash register and flag data transferred from 2 are stored in the card feed direction, KRC, FWD, and vertically multiplied flags of the "flag register," including "DN/REG" for the number of stages. Further, when the CR flag is inquired according to the flowchart of FIG. 83 of the MP mountain, if it is "1" indicating that there is a forced read, the "forced read" control is immediately executed.

In other words, at the beginning of the power-on reset, the sensor goes to the right.
Based on the sensor movement direction flag where " is stored, for example, if it has a "0" going to the right, the "right right" memory of the card data memo, which is the first memory diamond, is addressed. ■Write "C" to the register, and if it is a leftward "1", the "positive left" memory is also addressed. ■The register writes "E", and then writes "2" to SPU2. Transfer the data and execute the "read card" operation, and send the "card data" signal of 4 bits each word transferred from the SPU2 to the "correct right" according to the "card reading" flow shown in Figure 89. , write to each bit address of the "positive left" memory in the required order. According to the flowchart in FIG. 89, for example, when the sensor 92 moves forward in the right direction, the pixel areas 61 from "1" to "4" By transferring the 4-bit "card data" signal corresponding to the 4-bit "card data" signal, the "card data" signal corresponding to the pixel area 61 of the bit address "0" to "1" of the "right right" memory which has been addressed in advance is transferred. and also write the bit address “1”.
”, the signal of the pixel area “2” is set to the bit address “2”.
The signal of the pixel region "3" is written to the bit address "3", and the signal of the pixel region "4" is written to the bit address "3".

Next, ■ specify pixel area 61 of "1" at bit address "59" of the "positive left" memory by changing the address by combining the second bit of the register (bit with a weight of 2).
Write the "card data" signal corresponding to , and also write the signal of pixel area "2" to bit address "58", the signal of pixel region "3" to bit address "57", and write the signal of pixel region "3" to bit address "56". The signal for the pixel area "4" is written into the memory, and then the "right and left" memory is addressed again, and the next data transfer from the SPU 2 is awaited. Then, when the "card data" signal corresponding to the pixel area 61 "5" to "8" is transferred, the bit addresses "4" to "7" of the "right right" memory are transferred in the same way as above.
”, write the signals of pixel areas “5” to “8” in order, and write the bit addresses “55” to “8” of the “positive left” memory in order.
Write the signals of the pixel areas "5" to "8" in order in "52", and in the same way, every time the "card data" signal is transferred from SUP2, the "right right" memory and the "right left" memory are written.
Write to the required bit address of the memory, and finally write the "card data" corresponding to the pixel area 61 of the "right right" memory bit address "59" and the "right left" memory bit address "0" and "60". ” signal is written, the sensor movement direction flag is concatenated, and if it is “1”, it is changed to “0”, and if it is “0”, it is changed to “1”, and the sensor movement direction flag is changed to “1” when reading the next power code. Memorize the direction of movement. Also, the 8th
According to the flowchart in FIG. 9, for example, when the sensor 92 moves backward to the left, it first corresponds to the pixel areas 61 from "60" to "57" from the SUP 2 based on the reading scan of the pixel area 61 in one row horizontally. By transferring the 4-bit "card data" signal, the "card data" signal corresponding to the pixel area 61 of "60" is transferred to the bit address "0" of the "right left" memory which has been addressed in advance. Write the signal of pixel area "59" to bit address "1", the signal of pixel region "58" to bit address "2", and the signal of pixel region "57" to bit address "3". Write.

Next, specify pixel area 6 of "60" at bit address "59" of the "right right" memory by changing the address by combining the second bit of the register (the bit with a weight of 2).
Write the "card data" signal corresponding to 1, and also write the signal of the pixel area "59" to bit address "58", the signal of the pixel region "58" to bit address "57", and write the signal of the pixel region "58" to bit address "56". The signal of the pixel area "57" is written in the "57" pixel area, and then the "right and left" memory is addressed again, and then the next data transfer from SUP2 is awaited. Then, the pixel area 61 of “56” to “53”
Once the "card data" signal corresponding to is transferred, bit address "4" of the "right left" memory is transferred in the same way as above.
” to “7” in order, and write the signals of the pixel areas “56” to “53” in order, and also write the signals of the pixels “56” to “53” to bit addresses “55” to “52” of the “right right” memory. Write the area signals in order, and in the same way, every time the ``card data'' signal is transferred from SUP2, the ``correct left''
Write to the required bit addresses of the memory and the "right right" memory, and finally write "1" to the pixel area 61 at the bit address "0" of the "right right" memory and the bit address "59" of the "left" memory. At the stage when the corresponding "card data" signal is written, the sensor movement direction flag is concatenated, and if it is "1", it is changed to "0", and if it is "0", it is changed to "1", and the next card is written. The direction of sensor movement during argumentation is memorized. The MPU, which writes the "card data" signal to the "correct right ↓ correct left" memory of the card data memo according to the flow shown in FIG. Corresponding to the horizontal rows of the pixel area 61, the "regular right" memory is stored regularly in the same bit arrangement order, and the "regular left" memory is stored in the reversed bit arrangement order left and right.

After this, the data transferred from SUP2 according to the flowchart shown in FIG. 83, that is, the "card data" signal is positive (
PN data to identify whether it was sent as is (positive) or reversed to negative (reverse).
Store it in the PN flag of the "flag register" and use it in the subsequent "data set" flow, and reset the CR flag to "0" indicating no card discussion.
Next, set the DS flag to ``1'' indicating that there is a data set, transfer the contents of the ``flag register'' to the ``flag memo'' again, and then write the ``data set'' on the condition that the step status, which is the contents of the SN register, is not ``0''. Execute control. That is,
In accordance with the "data set" flow shown in FIG. 90, the MPU first sets the 2 flag to "0", which is 1, and sets the "right right" and "right" of the card data memo, which is the first storage device.
To specify the address of the "correct left" memory ■ Store the "C" data specifying the "correct right" memory in the register, then press PN
Based on the contents of the flag, if there is a positive "0", all bit addresses of the "data set memo" are cleared to "0" without needle selection, and a negative "0" is cleared across all bit addresses of the "data set memo". 1
”, set “1” across all bit addresses of the “data set memo” to indicate needle selection.

Then, based on the switching positions of the pattern selection switches SW1 and SW5 determined from the contents of the SW register, if, for example, all moyo or 1 moyo is selected, "model left A {4}
” Recall the content “d” of the memo, convert it into data “d-1” corresponding to the bit addresses of the “correct right” and “correct left” memories, and then write it to the “model left” register in the internal RAM, and do the same. Write the data obtained by converting in the same way from the contents of the memo ``Makuyu A [5]'' into the ``Mou right'' register, and furthermore,
Recall the contents of the memo, and if this is the data of "left a", change it to the data "300-a", and then change it to "right C".
When the data is "No.", change it to the data "2980C", convert the data corresponding to the bit address of "Data Set Memo", write it to the "Basic" register, and write it to the "Basic" register. Recall the memo contents of (7-) and ``Selection A ■'' and write them in the ``Selection Left'' and ``Kin Right'' registers after making the same conversion corrections as above. Next, ``Moleft'' and ``Moright The effective width (pattern width) of the knitting pattern selected as Moyo A is determined from the contents of each register of "Moyo W".
'' is stored in the ``T.REO'' which is the cash register, and the ``reference position'' is checked based on the pattern width of the customer.

That is, as shown in FIG. 98, if the reference position data of the customer in the "Basic" register is equal to the contents of the "Select Left" register, it is left as is; however, for example, if it is larger than the "Select Left" register, By matching this with the pitch of the pattern width and sequentially subtracting the contents of the "base" register, the reference position on the left that matches or is closest to the contents of the "selected left" register is found. If it is smaller than the contents of the "left" register, the contents of the "base" register are sequentially added according to the pitch of the pattern width, and the left reference position that matches or is closest to the "selection left" register is determined. seek. Then, if the horizontal double switch SWO is set to horizontal double from the contents of the SW register, the reference position is corrected to match the pitch twice the pattern width. After that, according to the flowchart in Figure 90, ask for the content of the flag 2, and if it is 1 or all, it is still set to "0", so from the contents of the SW register, select left and right, and Check the switching position of switch SW3. , Well, ■ By combrimenting the second bit of the register and changing it from "C" to "E", the "correct left" memory is addressed, and the "right" register is addressed. Content Te” to “59-
Calculate the data of ``59-h'' from the contents ``h'' of the ``Mozusa'' cash register, and put the ``59-e'' data into the ``Bakuza'' cash register. Write the data to the "More Right" register, and write the bit address number of the "More Left" memory specified by both registers to the above "More Left A'4}", "
Correctly correspond to the information effective width data of the customer in each memo of ``Moto A {5}''.

Next, in accordance with the flowchart in Figure 90, the MPU resets the base flag, which was also used during the previous standard correction, to "0", and then, for example, changes the contents of the "model left" register to "model count".
Assuming that you have written the data of "pattern width - 1" to the "model set count" register, write this to the contents of the "selection left" register starting from the standard position of the customer in the "base" register. Calculate the final value by adding 1 to the contents of the "mock count" and "mock set count" for each bit address until the matching position, and use the result as "
Set the base flag to ``0'', ``1'', and ``set count'' for each bit address, assuming the same as above, if it is double the value. 0
”, “1”, etc., and for each “1”, the “mock count” and “double set count” are added by 1, the final value is determined by calculation, and based on the result. Yo-flag and "mock count", "mock set count"
Set it on the cash register.

Next, the contents of the ``Hōgisa'' cash register are ``data counted''.
After writing the difference between the "Right" and "Left" registers into the "Data Set Count" register, for example, P
If the N flag is "0", the bit address is either "correct right" or "correct left" memory specified by the register at that time, and is specified by the "simulation count" register. "0 ↓ "1" content is called, and only when the bit content is "1", "1" is written to the bit address of the "Data set memo" specified in the "Data count" register.
”.

If the PN flag is "1", then either the "correct right" or "correct left" memory specified by the register at that time, and the bit specified by the "simulation count" register. Recalls the "0" and "1" contents of the address, and only when the bit contents are "0", writes "0" to the bit address of the "data set memo" specified in the "data count" register. . Then, after decrementing the contents of the "T data set count" register and subtracting 1, the borrow (B
"Data count" on the condition that there is no ORROW)
Add 1 to the contents of the cash register, and if there is no chocolate multiplication, decrement the "mock set count" register and subtract 1, and if there is no borrow, add 1 to the contents of the "mock count" register.
After the addition, return to the above-mentioned final bit write flow and repeat the same operation. If, "Mock Set Count"
If there is a boro in the register's 1 subtraction, reset the data of "pattern width - 1" to the "model set count" register, and reset the contents of the "model left" register to the "baku count" register, and then , the same bit write operation as above is repeated, but if there is a boro after subtracting 1 from the "data set count" register, the write operation to the bit address that matches the contents of the "select" register is completed. Assuming that, the "data set" control in the flowchart of FIG. 90 is completed, and then the DS flag is reset to "0" indicating no data set.

At this time, if there is a double value in the above memory bit write operation, make effective use of the base flag and add 1 to the contents of the "data count" register, and then write the base value. By asking for the contents of the flag, you can confirm that this is '
If it is “0”, it is rewritten to “1” and the flow immediately returns to the above memory bit write flow, but if it is “1”, it is rewritten to “1”.
0", the process moves to the flow of subtracting 1 from the "model set count" cash register.

Therefore, "correct right", "
If the bit address contents of the required memory are
It will now be written to two consecutive bit addresses of the "Data Count Memo" specified in the "Data Count" register. When the content is "1", correspondingly it is written to bit addresses "300" and "301" of "data set memo", respectively. Also, according to the flowchart in FIG. 90, if the pattern selection switches SW1 and SW5 are set to 2 according to the contents of the SW register, M-yen U sets the 2-like flag to "1" in advance.
”, and then first write the bits of “Momo B”.
”, “Select left B {○”, “Mo right B■”, “Mo left B (9}”)
Recall each content of the memo and write the data obtained by the same conversion correction as above in the "Basic", "Select Right ↓ Hishizu", "Shinyu", "Mozu" registers, and then proceed to the standard correction flow. and repeats the same control as above.

In particular, in the bit write operation of "Momo B",
The MPU is soldered on the left and right side, and the switch SW is used to check the operation of the left and right solders.
This is done based on the switching position of 2. Then, according to the flowchart in FIG. 90, the MPU that has finished the bit write operation for "MomoB" changes it to "0" based on the content "1" of the 2Moro flag stored earlier. , "Basic A ■", so as to perform the bit write operation of "Momo A",
“Sen-Right A ■)”, “Sen-Right A (7) ↓ “MoR A (5}”),
Recall the contents of the "Mozuo A'4'" memo and input the data obtained by the same conversion correction as above to the "Ki", "Sen'ri", "Sen's A'Mo'u", and "Bakuza" registers. Write.

Then, the same control as above is repeated to complete the "data set" control. According to the "data set" flow in FIG. 90, based on the ON/OFF contents of various switches SW2 and SW3, which is one of the needle selection mode setting means,
Select the required one of the first storage device "right right" and "right left" memories, and change the bit contents of "0" and "1" based on the switching of switches SW1, SW5, SW6, and SW8. The specified bit address (“
The operation of writing to the data change memory (which also corresponds to the same bit address) can be easily understood from the embodiment diagrams of knitting patterns illustrated in FIGS. 53 to 55.

In particular, in the flowchart in Fig. 90, by effectively utilizing the ``correct right ↓ ``correct left'' memory and specifying the address data outside of the address data of the customer inside the cash register, the required needle selection mode can be set according to the corresponding bit. Select the memory of the arrangement order, and furthermore, turn on and off the switch SWO, which is one of the needle selection mode setting means.
Based on the F contents, the same bit contents “0” and “11” are assigned to every two consecutive bit addresses of “Data Set Memo”.
By writing , the mode with double chocolate can be processed very easily. Therefore, after the control of the flow shown in FIG. Needle selection data necessary for realizing the knitting pattern set by the needle selection mode setting means is stored in each bit address part of the "data set memo" that corresponds to the knitting needles in a one-to-one relationship. The data for ``knitting needles selected at position B in Figure 3'' is set to bit content ``1,'' and the data for ``no needle selection (
The data of "knitting needles selected at position A in FIG. 3)" is stored as bit content "0". According to the main flow in FIG. 83, after finishing the "data set" control, the MPU asks SPU2 again whether it is "BUSY" on the condition that the start and rework flags are "0". If not, repeat the same "key scan" control and flag check as described above,
During this operation, if an external interrupt command of "L" is applied to the IRQ terminal, for example, the flow immediately shifts to the interrupt flow shown in FIG. 91, and returns to the original flow after the required interrupt control is completed.

That is, when an external interrupt command of "L" is given to the IRQ terminal of the MPU, when the "VIDEOI" signal rises from "L" to "H" and when the SPUI
In particular, an interrupt command from SPUI is output when carriages 13 and 2 are output as described above.
0 is running to the left, and the carriage center lines C and D correspond to the center position between the knitting needles 3.

Therefore, the MPU that performs external interrupt control according to the flowchart in FIG. 91 first checks the input of boat R8 after saving the registers such as Acc, X, Y, etc., and if the interrupt is from the SPUI, This is treated as a valid interrupt and the required interrupt control is executed, but if it is determined that the interrupt is not from the SPUI, then the "VID" given to the boat RII is
Check the ``EO2'' signal, and if it is ``L'', the interrupt command at that time is invalidated, and immediately return to the main flow after register recovery, and only if it is ``H'', the current interrupt instruction is The interrupt command is made valid and the required control operation is executed.

As is clear from the timing relationships shown in FIGS. 23 to 26, this rule applies when the carriages 13 and 20 are traveling to the right, and the carriage center lines C and D are aligned with each knitting needle. This is the point corresponding to the center position between 3 and
SP when carriages 13 and 20 are running to the left.
This also corresponds to the position where an interrupt command is given from the UI.
If the MPU determines that the interrupt control is valid when the carriage is traveling in the right direction according to the flowchart in Figure 91, it first asks whether the "left reference" signal is "H", and if it is If so, perform left reference count correction.

That is, while either the KL or the carriage is traveling from the left end of the needle bed to the right, the magnets 42 and 44 mounted on the carriage are
Based on the valid external interrupt when the left reference element 40' is close to the left reference element 40' (see FIG. 30b), the MPU stores "200" in "C REG" for carriage count, and
Check the "KL half-separate" signal at that time, and if it is "L", write "0" representing the K carriage to the KL flag, and then check the "phase" signal and if "L=0". If there is S
Write "0" in the "Nd" register for L number counting, and if "H=1", write "8" in the "Nd" register.
However, if the "KL discrimination" signal is "H", "1" representing L carriage is written to the KL flag, and if the "phase" signal is "0", "8" is written, and if it is "1", "1" is written to the KL flag. "0"
is written in the "Nd" register. As understood from FIG. 11, the magnet body 42 of the K carriage 13 or the L carriage 2
When the magnet 44 of No. 0 approaches the left reference element 401, the bit address number corresponding to the knitting needle from which the energization/disconnection control data of the electromagnet SL is to be read while satisfying the timing shown in FIG. 9 is "200". In addition, there is an electromagnet SLB corresponding to the cam theory position suitable for the start of energization in the state where the belt and K carriage are connected when the "phase" signal of "1" is output, and the "phase" signal of "0" is also output. When the "phase" signal is output, there is a haze magnet SL3.

In addition, in the connected state of the belt and L carriage when the "phase" signal of "1" is output, there is an electromagnet SLF corresponding to the cam theory position suitable for the start of energization, and also "0".
When the "phase" signal of is output, there is an electromagnet SL7. Therefore, by executing the count correction based on the left reference as described above, it is possible to secure the subsequent folding needle timing. If the MPU determines that the interrupt control is from the SPUI when the carriage is traveling to the left according to the flowchart in Figure 91, it first asks whether the "right reference" signal is "H" and then When it is likely that the
Follow the "LCH" flow, check the "KL determination" signal, and select "
If it is "H", "1" representing L carriage is written into the KL flag, and if "L", "0" representing K carriage is written in the KL flag, and then the right reference count correction is performed.

That is, when one of the KL carriages is being fed leftward from the right end of the needle bed and the magnets 42 and 44 mounted on the carriage approach the right reference element 38 (see FIG. 30a), an effective external interrupt occurs. Based on the ``MPU'' for carriage counting,
At the same time, store "399" in "C・REG", ask the "phase" signal at that time, and if "L=0", write "F" in "Nd" register for SL number count, and also write "H".
= 1”, write “7” in the “Nd” register. 10th
As can be understood from the figure, the magnet body 4 of the K carriage 13
2, or when the magnet body 44 of the L carriage 20 is close to the right reference element 38, the bit address number corresponding to the knitting needle from which the energization/disconnection control data of the electromagnet SL is read while satisfying the timing shown in FIG. is "399", and in the connected state of the belt and K carriage when the "phase" signal of "1" is output, there is an electromagnet SL4 corresponding to the cam theory position suitable for the start of energization. , when the “phase” signal of “0” is output, the electromagnet SLC
There is.

In addition, there is an electromagnet SL8 corresponding to the cam position suitable for starting energization in the state where the belt and the L-carrier are connected when the "phase" signal of "1" is output.
When the “phase” signal of “0” is output, the electromagnet SLO
There is. Therefore, by executing the count correction of the right reference as described above, subsequent needle selection timing can be secured. Also, according to the flowchart in FIG. 91, when the carriage starts traveling from the end of the needle bed, the MPU
If any of the "right reference" signals is "H", the F sign flag for carriage direction (hereinafter referred to as F flag)
If the carriage is traveling to the right, "1" is stored, and if the carriage is traveling to the left, "0" is stored, and these are used to detect reversal of carriage travel thereafter.

MP that executes valid interrupt operation according to the flowchart in FIG. 91
Based on the fact that the "left reference" and "right reference" signals are normally "1", if U is a valid interrupt when the carriage travels in the right direction, add 11 to the contents of "C REG". Then, the contents of the "Nd" register are also incremented by 1.

Then, except for the case where the data of "〇・REG" was transferred to SPUI immediately before the external interrupt, that is, the 57th
Unless the transfer SI flag, which indicates whether or not data is being transferred from the MPU to the SPUI, is "1" indicating that data is being transferred according to the timing operation in the figure, the boat 0
4 is set to "L" output, an external interrupt command is given to SPU2, and after the data bus lines of boats R12 to R15 are released, the first Recall the bit address contents of "Data Change Memo" which is the memory bag calendar of "C.
The bit address “220” that matches the content “220” of “REG”
Recall the contents of ``0 to 1'' of ``200''. When the bit content is "0", if the KL flag is "0", "A" data representing "K carriage needle selection not" is sent, and if the KL flag is "1", "A" data is sent. The "C" data representing "L carriage without needle selection" is transferred to the SPUI, and then the energization/disconnection is controlled based on the needle selection data that is the content of the "Nd" register after the above addition and is transferred at the same time. Transfer the number data "x" of the electromagnet SL to the SPUI.
If the retrieved bit content is "1" and the KL flag is "0", the "B" data representing "K carriage needle selection" is sent, and if the KL flag is "1" For example, "D" data representing "L carriage with needle selection" is
PUI and then the contents of the "Nd" register. In addition, if the external interrupt is from the SPUI when the carriage moves to the left, the MPU subtracts 1 from the contents of the "C REG" and "Nd" registers, and based on the contents after the subtraction, Calling from the "data change memo" similar to the above and transferring to SPUI are performed. Furthermore, “Nd
” The addition and subtraction of the cash register is expressed in 16 ships. For example, when adding “1” from “F”, it becomes “0”, and “1” from “ro”.
” When subtracted, it becomes “F”. After the fog needle data transfer to the SPUI is completed, the data to be transferred is transferred to the boat R12 again only if it is determined from the contents of the transfer S2 flag that the data is being transferred to the SPU2 immediately before the interrupt. ~ R15 is output, and the interrupt of SPU2 is normally canceled, so the register is recovered and the interrupt control in the flowchart of FIG. 91 is completed.

As understood from FIGS. 10 to 12, the 200 knitting needles 3 on the needle bed correspond to the bit addresses "200" to "399" of the "data change memo" in a one-to-one relationship, and , each bit address part of them is set to “0”.
”, “1” needle data are stored.

Therefore, after first performing the count correction on the left or right basis, the carriage center lines C and D arrive at the center position between each knitting needle 3 in relation to the movement of the carriage for the knitting needle pitches. Effective interrupt control is executed by an interrupt command etc. from the SPUI at each time, so based on this, the MPU establishes the required relationships as shown in FIGS. 10 to 12 according to the flow in FIG. 91. Then, from time to time, the needle selection data corresponding to the carriage center position is called up, the electromagnet SL is selected, etc. The knitting needle selection timing is secured and knitting needle selection control is performed in a certain order. In some cases, the MPU adds 1 to or subtracts 11 from the contents of "C.REG" according to the flowchart in FIG. 91, and then adds "CPCH" in FIG.
According to the flow, only if the content is "300", the data change pause flag (
DHP flag) is reset to ``0'' so that subsequent ``data change'' control can be performed without any trouble, and ``1'' is stored in the center flag for carriage center passage, indicating that the carriage has passed the center. Used for reversing carriage travel.

That is, when the carriage reverses its running direction, for example, from left to right or from right to left according to the flowchart in FIG. The MPU that performs control is “C・REG”
After adding and subtracting the contents of the "Nd" register by 11, first set the M sign flag (M flag) to "1" since the F flag has the opposite content to the carriage direction at that time.
Set it to .

As a result, even if the carriage reverses its travel, the flag setting and reversal correction described below are not performed immediately, and it is possible to avoid, for example, the case where the carriage continues traveling without turning around again and reversing. Only when the carriage has progressed further in reversal travel by one knitting needle, is the carriage reversal determined to be normal. Therefore, with the M flag set to "1", the MmU that performs the next valid interrupt control writes the contents of "0" and "1" that correspond to the direction in which the carriage is running and reversed to the F flag. Then, by executing carriage reversal control, the M flag is first reset to "0" to prepare for the next travel reversal, and the center flag is checked, and if it is "1" after passing through the center, , return it to "0" before passing, set the DC flag to "1" with data change, and set the P check flag (P flag) to 1”.

Further, the KL flag is checked, and only when it is "1" of the L carriage, the contents of the "Nd" register are rewritten to SL number data obtained by adding 8. In this example, KL carriages 13, 20
Regardless of whether the carriage is used or whether it is traveling left or right, the center line C of each carriage
, D is called out from the "data change memo", and the corresponding "S" number data of the "Nd" register is transferred to the SPUI.

Then, the SPUI stores each of these data in the 2(N) and 3(N) registers, which are software shift registers, and sends them to the MPU.
Each time the needle selection data is transferred sequentially based on the effective interrupt operation, in the case of K carriage, the K After the carriage has traveled for 13 knitting needles 3, the corresponding electromagnet SL is controlled to be energized and de-energized,
In addition, in the case of L carriage, each needle selection data is
After the L carriage has traveled the distance of one knitting needle 3 from the time it is called from the "data change memo", the corresponding electromagnet SL is controlled to be quickly de-energized. Therefore, there is no need to specially correct the contents of "C REG" when the carriage is reversed, and in the case of the K carriage, as is clear from Figures 10 to 12, the left and right needle selection points F Since the interval is a knitting needle pitch that is an integral multiple (3 times) of the number of electromagnets SL, there is no need to correct the contents of the "Nd" register, and only in the case of L carriage, the needle pitch at the left and right needle selection point F. Since the spacing is 1.5 times the number of electromagnets SL,
By inversion correction that adds 8 to the contents of the "Nd" register, the 9th
The timing shown in the figure can be secured.

According to the flowchart in Fig. 91, when the MPU sets the DO flag to "1" indicating that there is a data change when the carriage is reversed, the main flow shown in Fig. 83 returns after executing the effective interrupt control at that time. When proceeding with control,
Based on the aDC flag mentioned above, "data change" control is performed, and the SPU 2 is further caused to perform "card sending back" control. However, by checking the center flag and if it is "0" before passing through the center, by leaving the DC flag as "0", based on the carriage reversal at that time,
"Data change" and "card send back" controls are not executed. That is, the above-mentioned controls are executed only on the basis of carriage reversal after the carriage passes near the center of the needle bed and, more specifically, after the content of "C.REG" becomes "300". Also, according to the flowchart in FIG. 91, the MPU
When the P flag is set to "1" when the J-gear is reversed,
When performing subsequent effective interrupt control, the above-mentioned "C.R.
After adding or subtracting 1 to ``EG'' and ``Nd'' registers, ``C・RE''
Check the CO content, especially the first digit of "G", and confirm that this is "
When the value is either ``5'' or ``0'', the CR flag is set to ``1'' indicating that the card is taken, and the P flag is reset to ``0''.

Therefore, after executing the external interrupt control at that time, the MPU returns to the main flow in FIG. 83 and proceeds with the control.
Based on the R flag, "load read" control is executed, and "data set" control is also executed. That is, after the card 59 is sent back based on the reversal of carriage travel, the "forced read" control is not always performed immediately, and if the CR flag is set to "1". It is carried out only in Even if the “left reference” signal is “H”, the MPU that operates according to the flow in FIG.
If the carriage is moving to the left, the count correction for the left reference is not performed, and the "right reference" signal is
Even if the condition is "H", if the carriage is traveling to the right, the right reference count correction is not performed. That is,
When the carriage moves from the inner side of the needle bed toward the outer end, do not perform reference correction and use the normal "C.
By executing the 1 addition/subtraction operations of "REG" and "Nd" registers, needle selection timing is ensured over all the knitting needles on the needle bed. By the way, the M-circle U that operates according to the flow shown in FIG. , magnet body 42
, 44 is in the vicinity of the reference element 38, 44, the contents of the F flag are rewritten so that the carriage reversal correction is not performed again immediately after the carriage is reversed. At the same time, the content of the center flag is inquired, and the same processing as that for setting and correcting the carriage reversal flag is executed.

The timing of these reference corrections and carriage reversals can also be understood from FIGS. 23 to 26. By the way, when knitting a well-known lace rope using the L carriage 20, the L carriage 20 is placed on the auxiliary rail attached to the left end of the needle bed 2, as illustrated in FIG.
Place the K carriage 13 with a flat knitting cam arrangement on the auxiliary rail attached to the right end of the needle bed 2, and also place the L carriage 2
With the connecting pin 28a of the K carriage 13 set in a position where it can be connected to the belt 24, and the connecting pin 28 of the K carriage 13 set in a position where it cannot be connected (the magnet body 42 is also retracted in conjunction), both carriages are moved. By running the knitting needles alternately, in particular, each time the K carriage 13 performs two-step back-and-forth flat knitting, the selection cam mechanism 16a of the L carriage 20 selects the knitting needles 3 and transfers the stitches. Proceed.

At this time, as the magnet 44 mounted on the L carriage 20' approaches the reference element, "1" representing the L carriage is written in the KL flag, and various controls are performed based on the contents of the flag. , L carriage 20 also ensures needle selection timing, etc., which eliminates the need to provide a special KL changeover switch or the like and manually change it. According to the main flow in Figure 83, the MPU
is based on "key scan" control, and the starting flag is "
When set to 1, "Card reading", "Data set", "Data change", "Card send back"
, "Force read", and "Data set" in this order. By this, for example, "1" of card 59
When starting to organize the row of pixel areas 61 in the "" row as a female stage, the signal of the pixel area of the "1" row, which is the first row, is taken, and the "correct right" and "correct right" rows of the card data memo are taken. Based on the contents of the memory, various switches are selected as the needle selection mode setting means, and furthermore, the 200 bits of the "data set memo" are selected according to the key input data that is part of the step memo. The needle data is set, and the needle selection data in the "data set memo" after being set is transferred to the "data change memo" as is. Next, the card 59 is immediately advanced, the signal of the pixel area of the "2" stage is read, and the "Correct Right" and "Correct Left" memo are written, and then the "Data Set Memo" is written in the same manner as above. Needle selection data is set. Therefore, for example, when starting knitting with the K carriage at either the right end or the left end of the needle bed, the first carriage travels immediately
It is possible to create a needle selection pattern based on the card signal of the ``stage'' and select the striped needles 3 to the positions A and B in FIG. 3.

Moreover, when the carriage runs for the first time, the DHP flag is set to "1" in advance at the beginning of the train, so the DC flag is set to "1" with data change.
”, and when passing through the center, the DHP flag is reset to “0” and the center flag is set to “1”.
”, subsequent carriage reversal is enabled. Then, when the required striped thread is set on the thread of the K carriage and the carriage is reversed again, the content of the "data set memo" corresponding to the card signal of the "2" stage is changed to the "data change memo" based on the reversal. In other words, a needle selection pattern is created in response to the card signal of the "2" stage, and the card 59 is advanced to the stage "3".
” stage is read, passes through the “correct right” and “correct left” memories, and then is set in the “data set memo”. Now, with reference to the flowcharts of FIGS. 83, 88, and 91, the rework control of the MPU will be explained. In this example, during knitting, for example, the butt of the rope needle 3 collides with the cam, the rope yarn becomes entangled, and the carriage stops moving, or knitting fails, etc. If it is necessary to untie the thread, press the numeric key 110 to indicate the number of rows that the vertical fabric has been unraveled in K-carriage-only knitting, or the number of times the carriage must travel until it returns to the untied row in sea-seam knitting that also uses L-carriage. This configuration allows for easy resetting by operating the resetting key 118 after calculating the calendar number with . In particular, when the carriage has stopped moving and must be removed from the needle bed, it is preferable to remove the carriage before the carriage is removed, or at the latest before the removed carriage is re-entered from either the left or right end of the needle bed and connected to the belt. To,
In detail, before passing the standard, the setting is to operate the rework key 118 without the number of layers, which causes the error lamp L14 to blink, and in that state, the number of stages is set in the same manner as above, and the rework is performed. The key 118 is operated. Therefore, the MPU that performs the reshaping control according to the flow in FIG. If the number of layers is “0” even though there is “1” to In order to display the number error, transfer the "return number" of "0" steps, and since it would be bad if the carriage removal flag remains as it is removed, change it back to "00" without removing it. flag(
(consisting of 2 bits) is reset to "00", and the rework control at that time is ended.

However, if the KL flag has "0" representing the K carriage, the number of unraveling steps will be "0" and the green area will not be unraveled, but the pattern of the needle selection will be disturbed and the same step will be repeated again. Since there is a case where it is desired to perform needle selection, this is used as valid calendar number data to execute the reshaping control. According to the flowchart in FIG. 88, the MPU executes card feeding back at the current carriage reversal position based on the contents of the center flag at that time, especially when the content of the carriage removal flag is "00" indicating no removal. It is determined whether the carriage is stored or not, and it is determined whether or not to add one stage necessary to return the card 59. Also, if the carriage is removed, the F flag at that time is determined. Considering whether the carriage was removed while traveling in the left or right direction, from the contents of the pupil number data "〇・REG", it is immediately selected during the first carriage run in the initial stage of rework. It is determined whether the needle can be executed or whether it should be passed without one step of needle selection.

For example, in K-carriage knitting, if the yarn end after unraveling the knitted fabric is on the opposite side of the carriage position, needle selection may be performed immediately on the first carriage run; If there is a carriage on the other side, it is necessary to first pass the carriage through to the opposite side and then perform needle selection by reversing the movement.

In addition, in knitting the sheath stitch, by matching the needle selection data for stitch transfer determined on the card 59, for example, while the needle selection data at the initial stage of re-stitching is for rightward transfer,
If the L carriage is in the right position, needle selection can be performed during the first carriage run, but if it is in the left position, it is necessary to select the needle by passing to the right and then turning around and running to the left. be. According to the flowchart in FIG. 88, the MPU selects the card 59 that needs to be revised from time to time based on the contents of the pupil number data "〇・REG" and also from the contents of each flag.
In particular, in the case of the K carriage, compared to the L carriage, the total number of unraveling steps is less than the number of times the carriage travels by one step of needle selection, so add this. The “number of return steps” determined by correction etc. is “〇・R”
EG" and transfers it to the SPU 2, thereby causing the card 59 to be sent back by an amount matching the "number of return stages."

Then, the data transferred from SPU2 is written to "DN REG", and the card feeding direction is
The KRC, FWD, and vertically multiplied flag contents are stored in the "flag register", and then all bit address contents of the "data change memo" are cleared to "0". According to the flowchart in FIG. 88, when determining whether or not to perform needle selection in the initial carriage running direction at the initial stage of reshaping as described above, if the carriage is removed, the MPU selects either the right or left direction. If it is unclear whether the carriage will enter from
Due to the lack of data on which to base the above judgment, M.
For the time being, we proceed with provisional indexing control assuming that the carriage is approaching from the left.

However, when reshaping when the carriage is not removed, and even when it is removed, if the carriage has already passed the reference by entering and being connected to the belt, the above indexing control can be continued as is. If there is a needle selection during the first carriage run in the initial stage of reshaping, the DH flag is set to "1" indicating a data change, and if it is straight through, it is set to "0" indicating no data change, and then the DHP flag is set to "0" indicating no data change. Set the flag to "1" with pause,
Set the reshaping flag to "1", which means yes, then reset the carriage removal flag to "00", which means no removal.
The reshaping control in the flow of FIG. 88 is completed, and the process moves to 8 points in the flow of FIG. 87. According to the interrupt control flow shown in FIG.
'', if it is assumed from the contents of the outsign flag (consisting of 2 bits) that the reshaping control shown in FIG. 88 has not been executed yet, then as the basic data for the subsequent reshaping control, When it is "right reference", "01" means that the carriage entered from the right, and "01" is "left reference".
1 means that the carriage entered from the left.
0" in the carriage removal flag.

Therefore, after that, the MP that performs the reshaping control shown in FIG.
Based on the contents of the carriage removal flag "01" and "10", U assumes that the carriage has already entered and proceeds with the above indexing control. Also, according to the flowchart in Fig. 88, if the removed carriage has not yet entered, specifically, has not passed the reference, the MPU performs indexing assuming that the above-mentioned carriage enters from the left. By proceeding with the control, if it is determined that the first carriage run in the initial stage of reshaping is a straight passage without needle selection, the outsign flag will be set to "
10" with needle selection, set it to "11", write "0" with no data change in the DC flag, and write the DHP flag with "1" with pause.
'', the reshaping flag is set to "1", and the reshaping control in the flow of FIG. 88 is completed. 8th
According to the main flow in Figure 3, based on the above-mentioned reshaping control, if the reshaping flag is set to "1", after the "key scan" control ends at that time, the MPU performs the "
After that, the DC flag is checked, and if it is "oi" with no data change, it moves to the normal routine, but if it is "oi" with data change, 1”, then “Data change ↓ “Send back card”, “Read power card”
and “dataset” control.

Therefore, if needle selection is not performed during the first carriage run in the initial stage of reshaping, the content of all bit address parts of the "data change memo" remains as "01 data" without a clear needle. Along with this, the knitting needles 3 act on the sorting cam mechanisms 16 and 16a, but they are all aligned and guided to the A position (Figs. 3 and 4). Since the needle selection data based on the first card signal after resetting is stored in each bit address of "Memo," the needle selection pattern for the green needle 3 is immediately created as the carriage moves. During the first carriage run in the early stage of these reworks, the DHP flag is set to "1" with a pause in advance, so the DC flag can be immediately set to "1" with a data change. DHP after passing through the center
By resetting the flag to "0", subsequent carriage reversal is enabled. If the MPU proceeds with provisional indexing control and performs rework according to the flowchart in Fig. 88, with the carriage removed, the MPU performs "power read" and "data read" according to the main flow in Fig. 83. After executing the "set" control, corrections are made when either the left or right reference is passed as the carriage advances.

That is, according to the external interrupt flow shown in FIG. 91, the "left reference"
In addition, when correcting the "right reference", if a temporary index is made from the contents of the outsign flag, it is determined whether the temporary index was appropriate based on the contents of the flag, and the If it is correct that no needle selection was determined in the last carriage run in the initial stage of correction, leave the contents of the DII flag as is, and if the correction should be made to indicate needle selection, change the contents of the DC flag to ``with data change''. 1", and reset the outsign flag and carriage removal flag to "00", respectively. Therefore, the MPU is
After finishing the interrupt control at that time, when returning to the main flow shown in Fig. 83 and proceeding with the control, if the DC flag is "1", the "card discussion" for the previous rework is performed. , Following the "data set" control, further executes the "data change""card send back", "forced read" and "data set" controls, and in particular, "data change"
Only the control is completed in a very short time with enough time to select the knitting needles that the carriage first acts on. Furthermore, M
According to the main flow in Figure 83, the PU checks the contents of the SN register before performing the "data set" control, and if it is in the step state of "0" with the OK lamp lit, it immediately starts the "data set". Control is started, but at other times, that is, when key input data such as "Onnadai Dan" is in progress, or when a step memo is being called and displayed, the state returns to the "10" step state. With special emphasis on ensuring orderly control of "data sets".

In this example, the mode of needle selection control performed by the cooperation of the MPU and SPUs 1 and 2 can also be understood from the block diagram in FIG. , the relationship of signal exchange such as step memo etc. is clearly indicated.

Next, to explain how to use this example, first open the hatch 120 and press the step key 113 to turn on the lamp LI.
Set the pattern selection switches SW1 and SW5 with the button lit.

For example, if you want to create a striped pattern that repeats continuously over the entire course direction of the knitted rope by using the knitting pattern 64 arbitrarily selected on the card 69 that is the recording medium,
If you want to create a knitting pattern only on the desired part of the striped fabric by using knitting pattern 64 selected as "Moyo A", set it to "1 Moyo". , Also, on the same card 59, "Moyo A" and "Moyo B"
” If you want to embody a green pattern in a desired part of the knitted fabric by using two knitting patterns 64 selected separately, select “
2. Set it to "Moyo". Next, press the pattern selection switch S
Depending on the set position of W1 and W1, the data input points necessary for realizing the respective knitting patterns are sequentially called by lighting the lamps L2 to L13 each time the step key 113 is operated. Regarding each part of
Key in the desired data.

For example, in the case of "1 moyo", as illustrated in FIG.
It is included in pixel area No. 25.

Using the knitting pattern 64 of "Moyo A" effectively, set the pattern reference position corresponding to the pixel area numbered "1" on the needle bed 2 with the right knitting needle 3, and move from the left 5 provisional flea to the right. #50 striped needle 3
If you want to realize the knitting pattern over a period of time, respond to the lighting of lamp L2, turn on the calendar number “1”, and turn on lamp L3 to turn on “3”.
0" as the number of layers, lamp L4 as the number of layers, "1" as the number of layers, lamp L
Press 5 to read ``25'' and press right key 1 at lamp L6.
After operating 15, set the pupil to "1" and press left key 1 at lamp L7.
After operating the right key 115, the layer number is set to "50", and after the right key 115 is operated, the number of layers is set to "50" at the lamp L8. Then, when the OK lamp LO lights up, it is announced that the data input has been completed, so the key IN operation is stopped. If, ``
If all is OK, the OK lamp LO lights up immediately after the lamp L5, and data input ends. Also, “2
“Moyo”.

For example, as illustrated in FIG.
9, ranging from the 1st to the 30th step, "1" to "2"
Using the knitting pattern 64 of "Moyo A" included in the pixel area numbered "5" and the knitting pattern 64 of "Moyo B" included in the pixel regions numbered "26" to "50", the needle bed is 2, set the reference position of "Momo A" corresponding to the pixel area numbered "1" as knitting needle 3 on the right number 1, and move from knitting needle 5 on the left to honey striped needle 3 on the right 5. At the same time as embodying the striped pattern, "26
The reference position of "Momo B" corresponding to the pixel area numbered is
If you decide on the number 7 on the right and want to embody the knitting pattern from number 51 on the right to 3 spaces of striped needles of 10 bokashi, respond to the lighting of lamps L2 to L8 in the same way as in the case of "1 too" above. Then, in response to the lighting of lamp L9, "26" is counted as a calendar number, "50" is numbered as a layer number with lamp LIO, and "right 76" lamp is turned on with lamp LII. It is sufficient to key in the data of "Right 51" at L12 and "Right 100" at Lamp L13. However, in each of the above cases, the data that is activated by key N when lamp L6 is lit is "
Instead of “Right 1”, “Left 50”, Left “25”, Right “26”
You may also key in any of the lamps LII.
The data to be keyed in when the key is turned on may be "right 51" instead of "right 76", and the same knitting pattern is realized as a result. As can be understood from FIG. 54, the information effective width of the knitting pattern to be effectively used on the card 59 can be freely selected according to the worker's preference.
In particular, you are free to specify "Momo A" and "Moyo B" in completely separate ranges, or you may specify them in overlapping ranges, or even in completely the same range. You are also free to specify.

Moreover, the knitting patterns corresponding to "Moyo A" and "Moyo B" are set at mutually independent pattern reference positions in different needle selection ranges on the needle bed 2, as shown in FIG. 53, for example. It is also possible to embody the knitting pattern 64 on the card 59 in various ways. This allows you to create a variety of knitting patterns. Next, when the key IN data operation as described above is completed, the knitting pattern 64 of "Moyo A" and "Moyo B" selected on the card 59 is set to the switches SW3 and SW2.
Based on this, operate the required switches depending on whether you want to embody the knitting pattern as it is or change the left and right direction, and also set other switches SW0 and SW4.
, 7, and 8 can also be switched as desired.

And especially rubber knitting machines and changers (for KRC)
When knitting the well-known double knit stitch using KH, operate double knitting switch SW6 and
For the color scheme version using Chesojia for C, solder in forward and reverse directions and operate the switch SW8, but be careful not to operate the horizontal double switch SWO when using the series version, for example. As understood from FIG. 51, the knitting pattern 64 can be varied in various ways by operating various switches, and a wide variety of knitting patterns can be realized without creating a large number of cards 59. After operating the key SW operating mechanism 105, which is the needle selection mode setting means, inputting the data necessary to realize the desired knitting pattern and determining the needle selection mode as described above, the OK lamp is displayed. L.O.
is lit, insert the card 59, which is the required recording material, into the reading mechanism 68, and turn off the power switch 123 for the time being.
Set it to FF and operate the manual feed dial 77 to bring the set line 67 on the card 59 to the card setting position that matches the upper green edge of the insertion section 140, then turn the power switch 123 ○N again, and then turn the Operate the start key 117.

After that, if you want to start knitting two-color simultaneous knitting, for example, move the K carriage 13 from one end of the needle bed 2.
At least in the early stages of organization, the magnet body 4 mounted on the carriage
2 starts running further from the outer end than the position near the reference elements 38, 40, and runs to the other end.

At this time, the bit address contents of the "data change memo" based on the column signal of the first stage (starting stage) pixel area 61 are as follows.
The striped needles 3 of the K carriage 13 are called out sequentially every time the striped needles 3 travel one pitch, and after the K carriage 13 travels, each striped needle 3 is called as a so-called backward needle selection type. It is extracted in two positions, front and back. Therefore, in this example, before starting the pattern knitting of the desired pattern, K
After the carriage 13 has traveled once, knitting of the first stage can be started, and after the first stage needle selection pattern has been created, the K carriage 13 is finally set to the desired pattern cam arrangement and, for example, the second stage is knitted. For color-simultaneous bridging stripes, set the desired knitting yarn and start knitting.

After that, all you have to do is run the K carriage 13, and depending on the direction and right direction, controls such as card reading and card feeding are automatically performed to knit the fabric with the desired knitting pattern. can be organized very easily. In particular, the electronic buzzer beeps continuously and the card 59
When the continuous return control is notified, the carriage movement is stopped until the notification ends and then resumed, so that no disturbance of the knitting pattern occurs. By the way, if a procedure manual 300 as shown in FIG. 99 is prepared in the striping machine having the above-mentioned configuration, it is especially convenient for beginners in knitting.

That is, when knitting a desired knitted work, anyone can obtain the necessary data in advance according to each item of the procedure manual 300, write it in the memo column and entry column, and then start operating the knitting machine. It is easy to knit. For example, in the procedure manual 30 Kawako, it is specified that the gauge should be obtained by performing a trial knitting in advance, so the length value per 6 subtractions determined from well-known trial knitting or from experience etc. is entered in the step gauge memo field. 301, and also write the length value per 40th stitch in the eye gauge memo field 302, and write the scale position of the striped self-celebration dial when performing the trial green in the dial memo field 303, and then Enter the number of the stitch length (scale) used for the stripe width indicating device (knit leader) selected from the length value in the scale memo field 304.
Then, find the knitting width of the desired knitting work, such as the body, and enter the needle numbers of the left and right end needles of the knitting needles necessary to knit this in the memo columns 305 and 306. after that,
Create a pattern that you would like to embody in your knitting work, or select one from ready-made pattern cards, prepare a pattern card depicting the desired knitting pattern, and if all patterns are the same or one pattern is the same, Enter the female stage data for Momo A in the entry field 307, the final stage data in the entry field 308, the left data in the entry field 309, the right data in the entry field 3101, and 2 as well. In addition to Momo A, Momo B
Enter the model left data in the entry field 311, enter the model right data in the entry field 312, and then fill in each entry field 309, 31.
Enter in the respective entry columns 313 and 314 the number of the possible width determined from the numerical values 0, 311, and 312. Next, if you wish to knit 1 or 2 patterns, except for all patterns, write the reference position data of pattern A in the entry field 315, and enter the left end data and right end data of the needle selection range. are written in the entry fields 316 and 317, and when the number is 2, the reference position data of the row B and the left end and right end data of the needle selection range are also written in the entry fields 318 to 320. At this time, the key needle range can be determined easily and without error by referring to the numerical values entered in advance in the memo fields 305 and 306.
By also referring to the value of the width of the needle entered in 4, each data of the needle selection range can be obtained very easily. Therefore, after writing the required information in each memo field and entry field, use the same operating procedure as above to input the data prompted by the call display on the step lamp L to the written value in each entry field. If you follow the instructions and enter the required data in an orderly manner, you will be able to input the necessary data and start organizing immediately, compared to when there is no procedure manual. In this example, a first storage device (card) stores digital electrical signals obtained by extracting knitting pattern information recorded on a required recording medium (card) as bit contents corresponding to each layer of the recording medium. Separately from the data memo ``correct right'' and ``correct left'' memories, there are also ``data change memo'' and ``data set memo'' which are second storage devices for bit contents corresponding to each rope needle on the needle bed. According to the needle selection mode setting means for setting what kind of knitting pattern is to be realized on the green area by variously changing the knitting pattern recorded on the recording medium, the changes set in advance by the mode setting means are As embodied, the contents of the first storage device are proposed and stored in the "data set memo" of the second storage device, and then written from the "data set memo" in connection with the carriage reversal. It is characterized by outputting the memory contents to the knitting needles corresponding to each bit of the transferred "data change memo" and selecting green needles based on the contents. "Set" control can be executed with ease, and the readout control operation of stored digital electric signals from "Data Change Memo" related to carriage travel can be extremely simple, for example, by changing the settings of the needle selection mode setting means. It is an extremely simple control that simply displays the contents of each bit of the "data change memo", which is a second storage device, in sequence for each corresponding striped needle in a one-to-one relationship, without any relationship. The processing speed can be sufficiently shortened, and even high-speed carriage travel is satisfied. In this example, especially the sensor 9 shown in FIGS. 15 and 16
2 is a structure in which adhesive is poured in to fix the light emitting diode 94 and the phototransistor 97 in the respective mounting holes 95 and 98 to prevent them from escaping, but as an alternative method, for example, FIG. As shown in FIG. 101 as another embodiment, protrusions 92c are provided in the vicinity of the green sides of each of the mounting holes 95 and 98 of the case body 92a, and this is heated and pressurized with an appropriate tool. It may be configured to be pushed into each of the attachment holes 95, 98 and prevented from coming off.

This method can also be applied to other devices such as the photointerchanger element 32.
, 33, and the assembly is simple and reliable. In addition, in this example, SP
“T-stage feed back” performed by U2 according to the flow in Figure 73
Control is not limited to this, for example, the 102nd
The process may be executed according to the "T-stage sending back" flow shown in the figure as another embodiment.

That is, according to the flowchart in FIG. 102, based on the content of "T REG" which is the number of T-stage send-back stages, only the first - stage send-back is performed by 1 of the excitation pulse changes shown in FIGS. 40 a and b. Step timer XI is set to 10 seconds (CF register←9
> and set the 2 to 4 step timers X2 to X4 to 5.
By setting the skin second (CF register ← C), one step of return is performed after a total of 25 m seconds have elapsed, and then all 5 m
Each step is sent back after a total of 20 seconds have elapsed from the second timer set, and only the last step is sent back by setting all the timers x1 to x4 of each step to 10 m seconds.
During the T stage's return, the electronic buzzer BS makes a beeping sound. Then, when the number of stages for transporting back passengers in "T・REG" is "1", each step is set for 10 seconds and a total of 40 m seconds elapses, and one stage of transporting back is executed, and "2" When performing steps, perform the first step with a set of 10 seconds for 1 step and 5 seconds for steps 2 to 4, then perform a -step return with a set of 10 seconds for the next step, and perform "2". Finish sending back the stage. When the number of T-stages for sending back is small, the sending-back operation ends when the electronic buzzer BS just clicks q. Next, the features of this example and modifications are summarized as follows. 1. While programming the pattern on the card, the loom is placed in a set position so that the knitting pattern on the card can be seen, but before starting knitting the pattern, the sensor detects the starting row of the desired pattern knitted from the card. It is necessary to send it to the position where it is read (Kentori position J).

Therefore, an operation button (starting key 117), a card feeding device, and a control circuit thereof are provided to automatically feed the card from the setting position to the reading position. 2 When performing a pattern program on a rope machine, when setting the pattern selection on the pattern card, set the starting position (first row) and ending position (last row) in the row direction, and the starting position (left side) and end of the pattern width. When setting the position, or the left end position (select left) and right end position (select right) of the needle selection range, the setting step is entered incorrectly, i.e., the end is entered before the beginning, or the right end A control circuit is provided that automatically corrects the input by swapping the beginning and end, and also swapping the right and left ends, when it is input so that it is to the left of the left end.

3. On the knitting machine, when you try to start knitting by pressing the stitch start key 117 after setting the pupil number for a row different from the starting position (first row) of the pattern, the calendar number data is set to the starting position (first row) of the pattern.
A control circuit and a notification device are installed to check whether the stage is located between the final position (female stage) and the end position (final stage), and to notify the operator if it is outside the range. .

4. When programming a pattern on a knitting machine, the operator does not have to specify the pattern reference position and needle selection range.
A control circuit is provided to automatically calculate the value using a predetermined calculation method and write it in the step memo.

5 In the case of re-stitching on the knitting machine, it is necessary to return the card, so for example, in the case of pattern knitting, the number of rows of the unraveled fabric, in the case of sheath knitting, from the current row to the row to be returned. Calculate the number of travels of the L carriage,
A button (Aminai Sen-118) as a means for automatically returning the card, a card return device, and its control circuit were provided.

6 When re-stitching a knitting machine, the relationship between the yarn end and the carriage is determined from the relationship between the carriage running direction immediately before re-stitching or the position of the carriage and the number of unraveled rows, etc., and the yarn is adjusted for backward needle selection. When the thread end and the carriage are on the same side, the thread thread is passed through without needle selection or knitting during the first run, and only the needle selection is performed on the way back.After that, normal needle-by-needle knitting operation is performed, and the thread end and carriage are When the needle is on the opposite side, a control circuit is provided so that only needle selection is performed during the first run, and normal operation resumes after the yarn end and carriage are aligned.

In the case of forward needle selection, it is the opposite of backward needle selection in this example, and if the thread end and carriage match, normal operation will begin from the first time, and if they do not match, needle selection knitting will not be performed. All you have to do is lay it out so that it passes through.

7 In the striping machine, when the card signal is read and the read data is changed in various ways according to instructions from the pattern change instruction means (switch SW), etc., and knitting needles are selected as mist needle data, one knitting stage is terminated by the carriage reversal signal. If data for the next formation row is then calculated and output, it is conceivable that the data for the next formation stage may not be in time when a complicated pattern change instruction is issued.

For this purpose, a data buffer for needle selection (data set memo) was provided, and a control circuit was provided to calculate and set needle selection data for the next knitting stage during knitting of the previous stage. 8 In this example, the power switch 123 is connected to the manual feed dial 77.
If the card 59 is in the vicinity of the card 59 and the card 59 is fed by hand, the card 59 can be freely fed by hand immediately after being turned off, and then the system can be immediately turned on and the operation of the system can be started. 9 In this example, when an error occurs due to a failure of the sensor 92, the electronic buzzer spot is
Although it is configured to send out a digital electrical signal of "0" in place of the normal "card data" signal without causing an echo, for example, the error lamp L14 can be set so that it can be distinguished from other error notifications. The light may be turned on or blinked, and the electronic buzzer BS may also be emitted.

10 In this example, based on the knitting pattern 64 of the card 59, for example, when forming a repeating pattern in the row direction or forming a vertically facing pattern, each time the knitting of each unit pattern is completed, It is also free to configure the electronic buzzer spot to make a Q bird sound.

11 In this example, when knitting the lace stripes, especially K
Based on the contents of the L flag, when using the L carriage, it is also possible to ignore the horizontal double switch SWO that does not match this, and to create a configuration in which the horizontal double needle selection mode is not performed.

12 In this example, the OK lamp L which is a step lamp
In the “0” step state with O lit, press “DN・REG”
It is also possible to display the number of rows of customers on the almanac number display section 111, so that, for example, the need for row adjustment can be easily grasped and dealt with extremely appropriately.

13 In this example, if you try to start knitting without pressing the stitch start key while leaving the card set position, and if you reset the pattern height during knitting, for example, if you run the carriage, That is, it is determined whether the number of rows at the position where the current card is read by the sensor is within the range between the starting position (onnadai stage) and the end position (final stage) of the pattern, and if it is outside that range. If the knitting operation is started in a certain state, an error lamp, an electronic buzzer, etc. may be used to issue a warning.

14 In this example, when programming a pattern,
When setting the pattern selection, for example, start 1 of the row direction of the pattern,
In contrast to setting 5 at the end, if you set 5, 1, set `` at the beginning of the stitch so that a vertically reversed pattern is created.
The configuration is such that the signal string of the 5th stage is sent to the sensor reading position, and the pattern width is set to 1 and 10, but if it is set to 10 and 1, the left and right are However, it may be configured to function as an instruction for
Furthermore, when setting the range in which the pattern will appear (needle selection range),
If it is input in the order of the left end and right end, it will be left as is, and if it is input in the order of right end and left end, it will be selected so that it is left and right in the bit address order of "Data Set Memo". It may also be configured to set needle data and function as so-called pattern setting for the outer material.

15 In this example, when the row return key is operated, only the card returns to the set position and the "row number/REG (DN
)" etc. may be configured so that the contents remain as before,
This makes it possible to return to the original reading position normally, which is convenient because the card signal at the reading position can be easily checked during knitting.

16 In this example, the card insertion section 140 is particularly designed by making the internal structure of the reading mechanism a sealed type, and by increasing the air density inside the same by using, for example, a motor-rotated fan.
It is also possible to prevent dust from entering the sensor 92 and maintain the reading accuracy of the sensor 92.

17 In this example, as a special specification of the card 59,
/ Prepare a so-called cleaning card, which is made of a material that is easily charged with static electricity and has the ability to easily absorb dust etc. inside the reading mechanism, and has a flocked surface, etc., and set it in the reading mechanism and let it pass through. By doing so, dust and the like inside the mechanism may be removed.

18 In this example, especially when racing, a counter for counting the number of times the L carriage travels per formation stage and a memory for storing the contents of the counter are provided. By retracting it to the uncoupled position and changing the structure to leave the magnet body 42 in the position where it acts on the left and right reference elements 38, 401, etc.
The number of L carriage runs from the K carriage run to the next K carriage run is counted, and the count is called from the above counter memory according to the number of unraveling rows of the knitted fabric input at the time of reshaping.
Calculate the number of times the carriage has traveled, determine the number of card return stages required for reshaping, and based on the current position of the L carriage or the position to be entered, determine whether needle selection is required during the first carriage travel in the initial stage of reshaping. According to this, in either normal pattern knitting or sheath knitting, it is possible to perform re-stitching depending on the number of unraveled rows of the knitted fabric.

Next, the features of the needle selection method of the knitting machine in this example are listed below.

By the way, in the related structure of the left and right reference elements 38, 40 as a switch device for carriage detection in this example, and the magnet bodies 42, 44 as a switch action section,
In particular, as clearly shown in FIG.
The strength of the magnetic poles or the proximity distance is adjusted so that the external magnetic fields HK and HL exerted on the reference elements 38 and 40 have approximately the same strength as the bias magnetic field HB when 4 acts in close proximity. Therefore, extremely accurate left and right reference signals can be output without causing a depression in the output waveform as shown by the dotted line in FIG. 30a due to the application of an unnecessarily strong external magnetic field. However,
As shown in another embodiment in FIG. 103, according to the configuration in which the magnetic poles of the magnet bodies 42 and 44 are tilted and magnetized, a slightly stronger external magnetic field can be applied without requiring special adjustment of the strength. A simple configuration is sufficient. In addition, the reference elements 38, 4
The configuration of 0 is not limited to the SDME, and the polarity of the magnets 42 and 44 may be determined using other methods such as a Hall element. As explained above, the present invention is capable of forming a stitch by moving the green needle on a needle bed in which a large number of knitting needles are arranged in a row, thereby forming a stitch, or transferring a stitch. In a hand knitting machine that is equipped with two types of carriages that operate, and that controls such as needle selection are switched depending on which of the two carriages is operating effectively, the two carriages are provided with switch operating members of mutually different modes. In addition, the needle bed side is provided with a switch device for carriage detection which is operated by the switch acting member of each carriage and performs a different switch operation based on the mode of the actuated switch acting member. It is something to do. Therefore, especially when switching control means such as selection depending on which of the above two types of carriages is operating effectively, it is not necessary to selectively switch each time using a manual switching operation member. The carriage to be operated can be automatically determined, and control means such as needle selection can be appropriately switched to an operating state that is compatible with this.
