15a to 15h are carriage-mounted sorting cam mechanisms 16
Alternatively, eight handle plates are provided to perform needle selection control in cooperation with 16a, and these are arranged so as to be movable individually in the direction in which the knitting needles are arranged while being overlapped in the front-rear direction. Each of these handle plates 45a to 45h includes
Hook-shaped protrusions 46 for locking knitting needles as shown in FIGS. 6 and 9 are individually provided at every eighth pitch of the knitting needles 3, and are formed so as to be offset from each other as a whole. In this example, as particularly shown in FIGS. 10 to 12, the handle plate 45a has a hook-shaped protrusion 46 corresponding to the knitting needle 3 numbered 100 on the left side, and also corresponding to the knitting needle 3 numbered 99 on the left side. The hook-shaped projection 46 is held by the handle plate 45b, and as it is shifted to the right in order, the handle plates 45c, 45d, 45e...45
By repeating the arrangement order held by h, 45a, 45b..., the hook-shaped protrusion 4 corresponding to the knitting needle 3 of number 100 on the right side is
6 is held by the handle plate 45h.

Further, each of the handle plates 45a to 45h has a hook-shaped projection 46 which is arranged between the knitting needle 3 adjacent to the left side without corresponding to the lower part of the knitting needle 3 due to the action of the spring 47 hung on the left end of each handle plate. Although it is held in the working position, by moving to the right against the action of the spring 47, it can assume a working position in which it can lock the knitting needle 3 that has been pushed down.

In Figs. 3, 5, and 6, 48 is an electromagnet group which is an electric power conversion member, and 16 electromagnets SL0-9, A-F (expressed in hexadecimal), which corresponds to twice the number of handle plates 45, are shown. ) and each electromagnet
The oscillating plate 50, which is disposed directly above the SL, is attached at each front end so that it can move up and down with the rear end as a fulcrum, and is always connected to an electromagnet by the action of a tension coil spring 49.
A moving force is given to it in the direction of being absorbed by the SL. 51 is 16 electromagnets SL and shaking plate 50
U-shaped rods arranged in rows corresponding to each
Each of the rear legs 51a is threaded through the support frame 52 so that it can move up and down, and each of the rear legs 51a
The front leg 51b is supported so as to be able to swing in a horizontal plane around the front leg 1a, and the upper end of the rear leg 51a is moved to the lower front end surface of the rocking plate 50 by the action of upward biasing springs 53 that are always resiliently applied to each lower surface of the front leg 51b. They are installed so that they are in contact with each other.

54 is a cam wheel disposed above the front leg of the U-shaped rod 51, which is a bevel gear so that it rotates three times with one rotation of the pulley 22, or in other words, rotates once with the movement of the 16 carriages of the knitting needles 3. It is connected to the pulley 22 via a mechanism 55. The cam ring 54 has a 16
The horizontal action cams AC0 to AC are formed by sequentially shifting the phase by an angle (22.5 degrees) corresponding to one pitch of the knitting needle, and the length of the top surface of each horizontal cam is approximately four pitches of the knitting needle. They are arranged in a spiral shape so as to go around the cam ring 54 as a whole. Further, on the circumferential surface of the cam ring 54, 16 push-down cams BC0 to BC are formed in a one-to-one relationship with each lateral actuating cam AC, and each having a phase shift of 180 degrees with respect to the cam AC. As shown in FIGS. 5 and 6, the shape of the cam surface that bulges out on each outer circumferential surface gradually swells from the vicinity of both side hem edges of the corresponding lateral action cam AC, and the shape of the cam surface bulges out on the outer peripheral surface of the knitting needle. It is determined to have a top surface over an angular range corresponding to approximately two pitches. 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 faces are shown in duplicate as having the same cam surface orientation.

Each push-down cam BC of the cam ring 54 comes into contact with the front leg 51b of the corresponding U-shaped rod 54, and is lowered by the action of its cam surface against the elasticity of the upward biasing spring 53, thereby reaching its top surface position. At this point, the rear leg 51a is pushed down to the lower position shown by the solid line in FIG. For example, when the electromagnet SL is de-energized, as the cam wheel 54 continues to rotate,
The elasticity of the upward biasing spring 53 tensions the coil spring 49
In order to overcome the elastic force of
The front end of the swing plate 50 is floated together with the letter-shaped rod 51. At this time, the front leg 51b of the U-shaped rod 51 enters the interlocking locus of the lateral action cam AC, and as the cam wheel 54 continues to rotate, the front leg 51b of the U-shaped rod 51 receives the action of the lateral cam surface of the cam AC. The front leg 51b swings about the axis 51a. However, if the electromagnet SL is energized, the electromagnetic force will cause the shaking plate to
0 in the position shown by the solid line in FIG.
1 cannot return upward and remains in the lowered position. Therefore, even with the subsequent rotation of the cam wheel 54, the front leg 51b of the U-shaped rod 51 is below the movement trajectory of the lateral action cam AC, and the cam AC
remains unaffected by

In FIGS. 5 and 6, reference numeral 56 denotes 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 rod 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. The number of moving rods 56 is determined to be 16, which is an integral multiple of 8, which is the number of handle plates 45, so the number of moving rods 56 connected to each handle plate 45 is 2, which is the total number. Every seven pieces are connected to the handle plate 45 in the order of arrangement. And the sixth
As shown in the figure, the front end of the moving rod 56 that is inserted into the handle plate 45 other than the predetermined one is inserted into a laterally elongated play hole 58 in the handle plate 45, so that it is effectively unrelated.

In this example, the handle plate 45a includes an electromagnet SL0,
Two moving rods 56 corresponding to electromagnets SL 8 are operatively connected to each other, and two moving rods 56 corresponding to electromagnets SL1 and SL 9 are attached to the handle plate 45b, and SL is attached to the handle plate 45c.
2. The one corresponding to A is SL on the handle plate 45d.
3, B corresponds to the handle plate 45e, SL4,
The one corresponding to C is SL5, D on handle plate 45f.
Those corresponding to SL6 and E are operatively connected to the handle plate 45g, and those corresponding to SL7 and F are operatively connected to the handle plate 45h.

In FIGS. 3 and 6, the belt 24 is integrally connected to the carriage 13 or 20,
For example, when moving to the right, the cam wheel 54 also rotates in the direction of arrow E via the pulley 22 that rotates in the direction of arrow E in FIG. The action is sequentially applied to the knitting needles located on the right side of the knitting needle 3, and in relation to the carriage movement of one knitting needle 3, the action spreads to the adjacent knitting needles one by one. Also, if the carriage moves to the left, the effect will spread from the right side to the left side. Therefore, the U-shaped rods 51 are sequentially selected to be in contact with the lateral actuation cam AC or not to be brought into contact with the lateral action cam AC by controlling the energization and de-energization of the corresponding electromagnets SL.
in response to the vertical displacement of the handle plate 4 via the moving rod 56.
The needle selection control operation of leaving the needle in the needle selection inactive position or moving it to the active position circulates in the direction of movement of the carriage and at the same speed.

Furthermore, as clearly shown in FIG. 9, in relation to the carriage-mounted sorting cam mechanism 16 (16a), especially the reduction cam 18 (18a), when the butt 4 of the knitting needle 3 is pressed down, it is engaged. A handle plate 45 having a hook-shaped protrusion 46 that can be stopped is moved to the operating position by receiving the action of a transverse action cam AC via a moving rod 56, and the knitting needle 3 is engaged with the hook-shaped protrusion 46. , the temporary low butt needle is held only while being acted on by the cam AC, and is released when it crosses the separation cam 19. Therefore, in order to accurately produce these timings, the carriage 1
3 and 20 are configured such that they can be interlocked only when the connecting pins 28 and 28a are respectively fitted into the connecting holes 27 of the belt 24, and even when they are fitted into any of the connecting holes 27, the required timing is fixed. Secured.

However, since the arrangement pitch of the connecting holes 27 is set to 8 pitches (36 mm), for example, the knitting needles 3 corresponding to the hook-shaped protrusions 46 of the handle plate 45a are pressed down by the pressing down cam 18 (18a) of the carriage. Even when the handle plate 45a moves to the needle selection position, the plate 45a moves to the horizontal operation cam AC0,
8 is not specified, and in other words, depending on which of the connecting holes 27 the pin is fitted into, the horizontal operation cam
The AC is determined to be one of 0 to 8, and a phase shift of 180 degrees will occur. Therefore, when both the carriage and belt are newly connected,
The output signal of the phase element 32 is effectively utilized.

That is, in this example, as shown in FIG. 9, from the point of needle selection (shown in FIG. 9F) when each knitting needle 3 arrives on the line of the connecting pin 28 (28a) of the carriage, approximately 11 of the knitting needle 3 At the point in time, the handle plate 45 necessary for needle selection of each knitting needle 3 is determined in advance, and energization is started to the required electromagnet SL, and at the same time, approximately 5 pitches of knitting needles 3 have passed from the above-mentioned needle selection point F. At the point when the U-shaped rod 51 is on the front side of the top surface of the push-down cam BC and is gradually being lowered, the electromagnet SL is turned off. The setting is to start energizing, but
When newly connecting the above-mentioned carriage and belt, it is determined which of the two push-down cams BC with a phase shift of 180 degrees is at the appropriate rotational position to start energizing, and the corresponding electromagnet SL is energized. This is the start of the process.

In FIGS. 1, 5, and 13, 59 is a pattern card as a recording medium, and is made of a material such as a translucent plastic sheet such as polyester that has a rough surface that allows transparent writing. Consisting of The card 59 is provided with feed holes 60 on both sides, and vertical and horizontal square lines 61a in the middle.
61b, a large number of rectangular pixel regions 61 are formed in multiple stages, and in this example, each horizontal row consists of 150 rows with 60 pixel regions 61, with the leftmost pixel region 61 being "1" and the right In order to clearly indicate each pixel area number when counted sequentially, the area numbers "6", "12", "18"..."60" as shown in the figure are added, and the bottom row is marked " In order to clearly indicate the number of stages when counting upwards as ``1'', ``5'', ``10'', etc. as shown in the figure are added.

In addition, on the card 59, on the left side of the column in which the pixel area 61 is formed, the bottom row from the area 61 is
There is an instruction field 62 with a width of one square formed by shifting upward by 10 squares, and a field 62 for indicating the number of rows when counting upwards with the lowest row corresponding to the pixel area 61 of the "11" row as "1". 5", "10"... step instructions 63

Row instructions 66 such as "5", "10", etc. indicating the number of rows, such as counting upward from the lowest row corresponding to the area 61 as "1", are attached.

In the pixel area 61 column of the card 59, the pixel area 61 selected according to the desired knitting pattern is displayed on the card 59.
The knitting pattern 64 can be freely drawn by filling it with black ink or the like having a lower light reflectance than the surface of the pattern 9, or may be in a pre-printed recording format. The size of one pixel area 61 is made to match 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 satisfies 10.4 cm and 10.8 cm. , the pitch of the vertical square lines 61a is set to 2.6 mm, and the pitch of the horizontal square lines 61b is set to 1.8 mm, and a substantially actual-sized knitting pattern 64 is recorded.

The narrow thread change column 65 is, for example, a "color changer for hand knitting machines (parliers)" currently on the market.
By attaching the KHC-800 model or the "Color changer for rubber knitting machines" KRC-800 model to the left end of the needle bed 2, you can freely select four knitting yarns of different colors to create colorful knitted works. In this example, "1", "2", "3" and "4" added to each knitting yarn pause part of "color changer" are used when knitting.
The squares of the knitting yarns to be selectively used at that time are filled in black in correspondence with the knitting yarn numbers. Note that a card setting line 67 is provided on the card 59 at a location further away from the lowermost horizontal square line 61b that divides the column of the pixel area 61 by four square pitches (1.8 mm x 4).

In FIGS. 1, 5, and 14, 68 is a reading mechanism installed at the rear right side of the machine frame 1;
There is a feed shaft 70 rotatably attached to the unit support frame 69, and the pawls of a pair of left and right sprockets 71 that rotate integrally with the coaxial shaft 70 engage in the feed hole 60 of the card 59, which is a recording medium, so that at least the front Feed guide plate 72 and guide plate 7 with highly reflective surfaces
3, the card 59 is configured to be fed in stages. As shown in FIG. 14, on the right end of the feed shaft 70, there is a manual feed dial 77 that meshes with one intermediate gear 74 and is exposed to the outside through a recess 76 of the case cover 75 and can be operated as appropriate. A gear 78 to which rotation is transmitted is fixed, and a pulse motor 80 for stage feeding is connected to the left end of the gear 78 via a set of gear reduction mechanisms 79.

The pulse motor 80 is a 4-phase stepping motor with 2-2 phase excitation, and in this example, one step angle is 15 degrees.The pulse motor 80 moves the card 59 in the direction of the arrow G in FIG. When moving one step forward or returning one step in the opposite direction,
It is configured to always perform one step of feed-back with a continuous rotational movement (60 degrees) of 4 step angles,
Specifically, the rotational motion of 4 step angles is 60
After reducing the rotation amount by 1/5 through the gear reduction mechanism 79, the feed shaft 70 is rotated by 1/30, and this corresponds to one stage of the card 59 to advance or return the card 59. It is stipulated in

In FIGS. 14 and 16, the manual feed dial 77 is supported so as to be rotatable relative to a gear 81 that meshes with the intermediate gear 74.
With respect to the flange portion 82 formed integrally with 1,
The structure is such that the feed shaft 70 is manually rotated through a kind of friction clutch mechanism, which is in a press-contact state due to the action of the springy overwinding piece 83a of the snap spring 83 which has elasticity in the axial direction.
For example, when the step feed pulse motor 80 is energized to apply a holding force at each step position, the manual feed dial 77 slips and rotates, causing the feed shaft 70 to rotate.
Disable manual rotation operation. pulse motor 80
If the dial 77 is not energized, the holding force at each step position is weak, and the pressure contact state between the manual feed dial 77 and the flange portion 82 is ensured, and the dial 77
The feed shaft 70 can be freely rotated by this operation. 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. . When the flange portion 82 and the manual feed dial 77 are in pressure contact, when the required frictional force cannot be easily obtained due to the elasticity of the springy overwound piece 83a, that is, when the required frictional force cannot be easily obtained, that is, the transmission force is sufficient to manually rotate the feed shaft 70. If this is not possible, 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 troughs.

It hits the buffer compression spring 91 fitted to the left end of the threaded rod 84 and stops.

In FIGS. 5 and 14, the front upright wall of the guide plate 73 faces the intermediate portions of 60 horizontal pixel areas 61 corresponding to at least one row of horizontal pixel areas 61 on the card 59. A rectangular translucent window 73a with a width (1.3 mm) is arranged in a row (see also FIG. 34), and a mirror surface with a higher light reflectance than the surface of the card 59 is provided on the front side of the upstanding wall in front of the window 73a. It has a highly reflective coating. 92 is the sensor base 88
The sensor is a photoelectric reader fixed to the upper part of the card 59 and reads the pixel area 61 in one horizontal row of the card 59 in a horizontal line through each light-transmitting window 73a of the guide plate 73 as the base 88 moves. configured.

That is, the sensor 92 shown in detail in FIG.
In this case, a vertically long rectangular recess 93 is formed in the rear part of the main body case 92a made of black plastic, and the recess 93 is arranged along an axis that is inclined downward at a certain angle with respect to the card surface or the highly reflective coating surface which is the surface to be read. , a mounting hole 95 is provided from the back side of the case into which a light emitting diode 94 serving as a light source is inserted, and a small diameter hole 96 of 1 mm in diameter is provided to limit the area of light irradiated from the light emitting diode 94 by making the diameter slightly smaller than the mounting hole 95. Tokoro 93
is connected to.

Further, a mounting hole 98 into which a phototransistor 97 serving as a light receiving means is inserted from the back side of the case along an axis line tilted upward on the opposite side to the optical axis on the light emitting side.
It communicates with the recess 93 through a large diameter hole 99 that allows a wide range of light to be received by the transistor 97 . Reference numeral 100 designates a transparent glass for dust prevention that is fixedly attached to the stepped portion 93a on the front surface of the recess 93.

In FIG. 14, electrical connection between each photoelectric element of the sensor 92 and the fixed terminal plate 102 is ensured by a flexible printed cable 103. In FIG. The sensor 92 sequentially corresponds to the 60 light-transmitting windows 73a of the guide plate 73 within the range of moving forward to the right or left along the threaded rod 84.

The knitting pattern 64 recorded on the card 59, which is the recording medium, is changed in various ways using a key SW operating mechanism disposed on the rear left side of the knitting machine to set what kind of knitting pattern is to be realized on the knitted fabric. Various keys and switches (indicated by SW) are installed to represent the input device and knitting needle mode setting device.

First, let us summarize the characteristics of the setting mode of the needle selection mode in this example. First, from among the knitting patterns 64 recorded on the card 59, the needle selection mode can be set arbitrarily in the course direction or the well direction (column direction). By effectively utilizing the selected range of patterns, it is possible to continuously create knitting patterns in units that respond to the pattern width on the knitted fabric, and also specify the reference position at which the knitting patterns should be created. Then, the knitting needles 3 can be sorted.

As a second feature, in order to realize the knitting pattern in the range arbitrarily selected on the card 59 at the desired position of the knitted fabric, the needle selection range and reference position in which the knitting needles 3 should be selected on the needle bed 2 are determined. It can be specified freely. Moreover, as a third feature, the knitting pattern recorded on the card 59 can be changed in various ways, such as by reversing the left and right directions of the pattern, reversing the black and white of the pattern to make the pattern reverse, or changing the knitting pattern recorded on the card 59. By freely specifying, for example, enlarging the image twice in the horizontal direction, it is possible to create many knitting patterns extremely easily.

The fourth feature is that the knitting pattern can be changed in various ways in the row direction of the knitted fabric, such as reversing the vertical direction of the pattern, doubling the pattern in the vertical direction, or changing the pattern in the vertical direction. You can freely specify whether to repeat the pattern vertically while keeping the pattern the same, or alternately change the vertical direction of the pattern to the well direction (column direction) to perform vertical facing. You can easily create rich knitting patterns.

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

Furthermore, as a sixth feature, a so-called call-answer type data input device is adopted in order to specify each range and reference position, etc., and each data can be input by operating a numeric key in response to each call display. You can enter freely. Furthermore, the seventh feature is that the contents of each range, reference position, etc. specified at any time can be 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 knitting and lace knitting, using the already well-known so-called "color changer for rubber knitting machines", and furthermore, it is possible to handle knitting failures. It has features such as being easy to modify.

All electrical signals related to the sensor 92, DC motor 86, etc. are collected in a needle selection control device consisting of a 4-bit microcomputer, and are processed extremely quickly according to pre-programmed control operations. A series of needle selection control operations are accurately executed.

First, the operating circuits of the various parts that form digital electrical signals suitable for being collected in a microcomputer from the above-mentioned detection elements, sensors 92, etc. will be explained with reference to FIGS. 21 to 34.

In FIGS. 21a and 21b, 124 is an operating circuit of the VIDEO element 33, and the positive terminal (5V) of a DC power supply is connected to each terminal of "+5V" in the figure (the same applies hereinafter), and the light emitting diode 33a, c is driven by direct current through current limiting resistors 125 and 126, respectively, and load resistors 127 and 128 are connected to the emitters of phototransistors 33b and 33d, so that the emitter output signal of one of the phototransistors 33b is sent to the Schmitt circuit. After being waveform-shaped via 129, it is output as an output signal of "VIDEO1", and the emitter output signal of the other phototransistor 33d is also output via 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.
When rotating in the FWD direction (rightward), an output signal that shifts to the right side in the figure is obtained. As is clear from FIGS. 23 to 26, the "VIDEO1" signal is out of phase with the "VIDEO2" signal based on the 31 rows of protrusions on the disc 29 rotating in the "FWD=1" direction when the carriage runs to the right. I will be late,
Also, when the carriage is running on the left, "VIDEO1"
will lead in phase compared to "VIDEO2". Moreover, the cycle of falling from "H" to "L" or rising from "L" to "H" in "VIDEO1" is synchronized with the carriage travel, and each needle is adjusted in relation to the pitch of knitting needle 3. In particular, in this example, when the carriage is running to the right, the "VIDEO1" signal rises from "L" to "H", and when the carriage is running to the left, the "VIDEO1" signal rises from "H" to "H". The point in time when the line falls to "L" coincides with the point in time, and each point in time also coincides with the point in time when the carriage center line C or D corresponds to the approximate center position between the knitting needles 3.

In FIG. 28, 131 is the left and right reference element 3.

is being input. Output signals of left and right reference elements 38, 40 (negative input terminal voltage of operational amplifiers 132, 133, positive input terminal voltage changes oppositely)
As shown in FIG. 29, the K carriage 13
When either of the magnets 42, 43 approaches, Vl becomes lower than the normal output voltage based on the NS polarity, and therefore the operational amplifiers 132, 13
When the "carriage detection signal" with a higher level VH than 3 is output and the magnet 44 of the L carriage 20 approaches, the output voltage becomes Vh higher than the normal output voltage based on the SN polarity, and therefore the operational amplifier 132,
133, a lower level "carriage detection signal" is output.

Comparators 134 and 136 are operational amplifiers 13
It is used to determine KL carriage based on the "carriage detection signal" from 2, 133, operates with reference voltage V2 as the level boundary, and outputs "H" K carriage signal KP1 from inverters 138, 139 in the subsequent stage. and comparators 135 and 13
7 similarly operates using the reference voltage V1 as a level boundary, thereby outputting an "H" L-carriage signal LP1.

An OR circuit 140 connected to an inverter 138 and a comparator 135 outputs a K carriage signal KP1.
Regardless of the distinction between the L carriage signal LP1 and the L carriage signal LP1, when any of them is input, the "left reference" of "H"
The OR circuit 141 outputs a signal and is connected to the inverter 139 and the comparator 137.
Similarly, K carriage signal KP1 or L carriage signal LP
1 is input, the OR circuit 142 connected to the comparators 135 and 137 outputs the "right reference" signal of "H", and furthermore, the OR circuit 142 connected to the comparators 135 and 137 determines whether the magnet 44 is close to either the left or right reference element 38 or 40. Even in this case, when the L carriage signal LP1 is input, the "KL determination" signal of "H" is output.

30a and 30b show the output waveforms of each part of the operating circuit 131 with specific correspondence between the magnets 42, 43, 44 and the reference elements 38, 40, etc. A reference signal of "H" is output at intervals corresponding to approximately one pitch of 3, and when the carriage is running to the right at approximately the halfway point, "VIDEO1" 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.

In FIG. 31, 143 is an operating circuit for the phase element 32, in which the light emitting diode 32a is driven with direct current via a current limiting resistor 144, and a load resistor 145 is connected to the emitter of the phototransistor 32b.

43 output waveforms are shown, and each time element 32 corresponds to three upright walls 30 of code disk 29, the "phase" signal changes to "0" of the digital code word, with the relationship as shown. " is output as an "L" electrical signal corresponding to the digital code word "1", 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".

By the way, in the interlocking relationship between the code disk 29 and the cam wheel 54 using the belt 24 as a driving source, when the phase element 32 corresponds to the approximate center of any of the three upright walls 30 of the code disk 29, , cam wheel 54
When the lateral operating cams ACB and ACC are operating the U-shaped rod 51, and when corresponding to the middle of the part where there is no upright wall 30, the lateral operating cams AC3 and AC4 are operating the U-shaped rod 51. It is assembled as it is.

Therefore, for example, when the magnets 42 and 43 of the K carriage or the magnet 44 of the L carriage connected to the belt 24 are brought close to either the reference elements 38 or 40, the phase element 32 is one of the three on the sign disk 29. A position near the approximate center of any of the upright walls 30,
Alternatively, if the element 32 corresponds to the intermediate position of the portion without the upright wall 30 and the lateral actuating cams ACB and ACC of the cam wheel 54 are operating the U-shaped rod 51, the element 32 moves toward the upright wall 30. Correspondingly, when the lateral operating cams AC3 and AC4 are operating the U-shaped rod 51, the element 32 corresponds to the portion where the upright wall 30 is not present.

As described above, each of the reference elements 38, 40 in either the K carriage or the L carriage
The rotational position of the cam wheel 54 can be detected by the "0" or "1" of the "phase" signal outputted when approaching either of the two, and the connection relationship between the carriage and the belt 24 can be known. .

At the same time, a load resistor 159 is connected to the emitter of the phototransistor 97, and the transistor 97 outputs "H" depending on the amount of light received from the operational amplifier 156 that constitutes the non-rotating amplifier circuit at the subsequent stage. The analog electrical signals of are output as "sensor outputs", specifically, the analog electrical signals of Fig. 34a,
As shown in b, when the sensor 92 corresponds to the highly reflective coating of the guide plate 73, the light emitting diode 9
The projected light from the card 59 is reflected well and becomes an extremely high level VH, and passes through the transparent window 73a to the card 59.
When scanning the pixel area 61 on which the upper pattern is not drawn, the light reflected from the card surface or transmitted through the card is reflected again from the front surface of the guide base plate 72, and the level is slightly lowered to a medium level. VM, and when scanning the pixel area 61 where the pattern 64 is drawn, the level further decreases to the low level VL.

Comparator 160 is used to separate and form data pulses from the "sensor output"signal;
With the reference voltage V1 as the level boundary, when the "sensor output" is at a level lower than this, the "H" data pulse DP1 is output, and the inverter 1

In addition, the SPU 2 scans various keys and switch SWs, controls the drive of the pulse motor 80 and DC motor 86, performs card reading control, etc., and also controls the transfer of detection data etc. to the MPU. However, the data representing each control start command is sent to the MPU at the required time.

In other words, all electrical control parts of the system are centrally controlled by the MPU, and various specific control operations such as key switch scanning and card feeding are performed.
The configuration is such that SPU1 and SPU2 assist, and for this purpose, a bus line for data transfer is secured between each processor.

As shown in , when the power is turned on, the voltage rises slower than the DC power supply voltage of the "+5V" line, and when the power is turned off, it falls faster.

In the address configuration of the external RAM shown in FIG. 42, the details of the contents of each flag allocated as the system flag memory are the same as the contents of the flag register of the MPU shown in FIG. The contents of a part of the flag register (Y addresses 0 to 4) are stored for the purpose of protecting the contents of the flags at the time of operation, and are effectively used when the power is turned on next time. The address parts indicated by "(1) to (c)" in the external RAM correspond to the lamps L1 to L, respectively.
It is used as a step memo to store the input data entered in response to the 12 lighting displays.
For example, the numeric data corresponding to lamp L1 is stored in the address part of "start stage (1)", and the numeral data corresponding to lamp L2 is stored in the address part of "last stage (2)". In addition, in the address part such as "selection left A(6)" which requires left and right data in addition to the numeric data, one word of each (A4 to 7
→D address) is allocated for left and right discrimination data, and is stored with numerical contents of left (L)=1 and right (R)=2. Data with no left/right distinction, that is, "0" data, is always stored in the left/right distinguishing address portions of other step memos "(1) to (4)" and "(8), (9)". Ru. In addition, the address part of "DN REG" for multi-stage (middle stage) is equipped with a sensor 92.
The stage number of "0" is stored as the stage number data representing the stage number of the corresponding pixel area 61 on the card 59 or the card set state, and the address part of "Clear (D)" is set to "0" in the number display section 111. Data for clear display of "0", that is, data of "000" is always stored, and "0" is also stored in the address portion for distinguishing left and right.

In the address structure of the external RAM shown in FIG. 42, each address part of "right right" and "right left" is assigned as a card data memo which is a first storage device. Right right”
A digital electrical signal obtained when the sensor 92 scans forward and backward toward the right, specifically, a "card data" signal output from its operating circuit 157 (FIG. 33) is stored in the memory as a hit. The card data is stored in output order from address 0 to bit address 59, and the card data obtained when the sensor 92 scans back and forth to the left is stored in the second storage section, ``normal left'' memory. '' signals are stored in order of output from bit address ``0'' to bit address ``59''.

These first and second storage units, ``Right Right'' and ``Right Left'' memories, correspond to the pixel areas 61 on the card 59 that are sequentially scanned by the reciprocating movement of the sensor.
Each bit corresponds to one pixel area 61, and the content of each bit is "card data".
As specified by the same output order of signals, e.g.
Regardless of whether it is traveling in a round trip, the "card data" signal output at the beginning of each trip is stored in bit address "0", then bit address "1", bit address "2", and so on. are stored in order, and the bit address "59" is stored at the end.
The "card data" signal based on the pixel area 61 of "1" is always stored at bit address "59" of the "correct right" memory, and the signal based on the pixel area 61 of "2" is always stored in the "correct" memory. The signal based on the pixel area 61 of "60" is stored in bit address "1" of the "right" memory and bit address "58" of the "right left" memory. Bit address ``59'' of the ``right right'' memory is set to bit address ``0'' of the ``right left'' memory.
is memorized. That is, the ``normal right'' memory stores bits in the same order as the pixel area 61 on the card 59, and the ``normal left'' memory stores the bits in reversed order. The 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, and the second address part corresponding to each knitting needle 3 on the needle bed 2 is Each bit is assigned as a storage device, and each bit corresponds to the knitting needle 3 in a one-to-one relationship, so that, for example, a digital electric signal of 1 with needle selection and 0 with no needle selection is stored, and Assuming that the bit address corresponding to the leftmost knitting needle on the needle bed 2, that is, the knitting needle number 100 on the left, is "200",
From this, the bit address corresponding to the knitting needle "No. 99 on the left" adjacent to the right side can be counted in order such as "201", and the bit address corresponding to the knitting needle "No. 100 on the right" can be specified as "399". There is. FIG. 42 partially illustrates the bit address structure of "200 to 399" in these "data set memo" and "data change memo".

Data memory RAM configured inside the MPU
(hereinafter referred to as internal RAM) has the address configuration 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. Further, the contents of each register assigned as a working register are shown in FIG. 43rd
In the internal RAM of the MPU shown in the figure, especially the SL
The "Nd" register for number counting is a soft counter that counts in hexadecimal numbers "0 to F" corresponding to the numbers of the 16 electromagnets SL mentioned above, and the "C REG" for carriage counting is " represents the carriage position on the needle bed 2, and
At least 200
It is a soft counter that performs a counting operation of ``~399'', and in practical terms counts in a range that exceeds this range. Similarly, “K0,” for ADDR count.
K1” cash register is the first storage device mentioned above, “right right”,
It is a soft counter that counts from 0 to 59 so as to specify a common bit address for the ``right and left'' memory, and is also a ``D'REG'' for transfer.
(D2 to D0) store numerical data to be displayed, and are effectively used especially when data is transferred from the MPU to the SPU1.

On the other hand, the internal RAM of SPU1 has the address configuration shown in FIG. 48, and the details of each flag assigned as a system flag register and working register and the contents of the register are as shown in FIG. 49, especially , For transfer, , the cash register is
Stores the number data transferred from the MPU,
Data obtained by adding so-called zero erasure processing to the contents of each register is stored in "D.RES" (D2 to D0) and effectively used for subsequent display control.

The internal RAM of the SPU2 has the address structure shown in FIG. 46, and the flags assigned as system flags and working registers and the register contents are as shown in FIG. 47.

Now, the specific control operations of the MPU and SPUs 1 and 2 having the above configuration can be understood from the flow diagrams shown in FIGS. 57 to 87. The explanation will be made with reference to the address configuration diagram shown in FIG. 49.

First, the control operation of SPU1 is shown in Figures 57 and 60.
To explain according to the flowcharts shown in FIGS. 63 to 63, in the main flow shown in FIG. By outputting "L" from all ports O0 to O3, the segment display on the numeral display section 111 remains extinguished, and by outputting "0" to the P port, P0 to P3 are set to "L". At the same time, ports R0 to R11 are set to "L" output, and all electromagnets SL0 to SLF are placed in a power-off state.

Subsequently, the SPU 1 causes the numeral display section 111 to display the contents of "D.REG" in segments according to the "Display" flow shown in FIG. Specifically, first store ``4'' in the register for specifying display digits, then set register ``Dn'' to address ``D2'', and read the contents of ``D2'' based on this. On the condition that it is not "F", output to port OH (O4 ~ O7), and immediately after, "4" which is the contents of the register is output to port OL (O0 ~ O3)
, and according to the pre-programmed PLA, "4" → port O2 = H, "2" → port O1 = H, "1" → port O0 = H, "0" → H
According to the PLA configuration without output port OL,
Drive the segment element SE2 of the upper digit,
The contents of "D2" are displayed by lighting.

Then, after continuing the lighting display of the same element SE2 for about 200 μs, it disappears, then "2" is stored in the register, "Dn" is set so that "D1" is addressed, and then it is turned off again. The contents of “D1” called in the same manner as above are transferred to segment element SE1.
lights up for approximately 200μ seconds. Next, store "1" in the register, set "Dn" so that "D0" is addressed, and then write the contents of "D0" called in the same manner as above to segment element SE0.
lights up and displays. If called "D2"~
If the content of "D0" is "F", the corresponding segment element SE is not driven, and for example,
If the content of "D.REG" is "FF0", "0" is displayed only in SE0, and nothing is displayed in SE2 and SE1 due to so-called zero erasure.

In FIG. 61, SPU1 performs a timing operation to check whether port R13 is "L" while performing the "display" control operation as described above. After setting the port output, set the built-in timer in SPU1 to 200μ seconds and start it, then check whether port R13 is “L”, and when the timer measures 200μ seconds, the timer overflows (ends). The operation of checking whether the flag is set is repeated. That is, the SPU1 is in a state where the data that is the basis of control is transferred from the MSU, and specifically, when the MPU transfers data according to the timing flow shown in FIG.
Numerical data of "A" representing "without needle selection", numerical data of "B" representing "with needle selection", data of "C" representing "hatch open (OPEN)", data of "hatch closed ( After setting the data "D" representing "CLOSE" and the numerical data "0" to "9" representing each digit of "display data" in ports R12 to R15 in advance, By setting “L” output, SPU1
checks port R13 to determine whether this is an "L" signal transfer command. And port R13 is "H" without data transfer from MPU
If the timer over flag is set first, the above-mentioned "Display" control operation will continue as is, and the contents of "D・REG" will be displayed in the number display section 1.
While in the ``display mode'' in which 11 is continuously displayed, the above-mentioned ``display'' control operation is repeated to perform three-digit segment display using a dynamic drive system. However, SPU1 is port R
When 13 inputs an "L" signal indicating data transfer, it stops the "display" operation and immediately receives data transferred from the MPU according to the timing flow shown in FIG. That is, if the port R13 is an "L" input, the data transferred through the ports K0 to K3 is immediately stored in the register, and the port R14 is outputted "L" to notify the MPU of the completion of the transfer. MPU confirms the completion of this transfer at port R9, outputs "F" data to ports R12 to R15, and then returns port O5 to "H" again, and SPU1 returns port R14 to "H". Immediately thereafter, various control operations based on the transferred data are executed according to the main flow shown in FIG.

For example, while the above "display" is operating, new "number (display) data" from "0" to
If any digit data of "9" is transferred, in order to transfer a total of 3 digits of data, first transfer the contents of the register, which is the first transfer data, to the register, and then repeat the same process as above. Perform timing operations
The second transfer data from the MPU is transferred to the register, the contents are transferred to the register, and then the third transfer data from the MPU is stored in the register again with the same timing operation. After this, SPU1 will be the 6th
Move to the “data change” flow in Figure 2,
,, Adding so-called zero erasure processing to the three-digit contents of the cash register, specifically converting "0" data that does not need to be displayed based on the three-digit data to "F", etc. Transfer the data as is to D2 to D0 of "D・REG". for example,
If the content of , , is "000", convert it to "FF0", if it is "010", convert it to "F10", and if it is "100", leave it as is and use "D・REG". I am trying to transfer it to .
Then, after executing the above-mentioned "data change", the SPU1 returns to the "display" operation and displays the new data transferred from the MPU on the number display section 1 instead of the segment contents that had been displayed up until then.
Continue the "display mode" displayed on 11,
A timing check operation is performed from time to time. Furthermore, the "number (display) data" transferred from the MPU is stored in "D'REG" in its internal RAM.
The content of each digit is D, starting from the upper digit D2.
Each numerical value up to 0 is transferred,
It matches the digit order of "D・REG" for display on SPU1.

In some cases, if the data transferred from the MPU is "D", it is determined that this is the numerical data representing "hatch closed", and "0" for hatch closed is stored in the hatch flag register, and then, port
Set the output to OL to “0” and output the segment element.
After canceling the lighting display by SE2 to SE0,
It enters the "standby mode" in which only the check operation at the above timing is repeated, and port R13 becomes "L".
I keep asking if it is. That is, when the hatch 120 is closed, there is no need to display anything on the number display section 111, so the "display" operation described above is omitted and the system continues to wait for the next data transfer from the MPU.

For example, when needle selection data for "A" and "B" is transferred from the MPU, the transferred data is stored in the register, and then the data transferred from the MPU is waited for and the same timing as described above is performed. The machine enters the check operation, receives the "electromagnet SL number" data that is transferred following the "needle selection yes/no" data, and stores this in the cash register. and,
Based on the contents of the register, if this is "A" representing "no selection", the output port corresponding to the SL number which is the contents of the register is set to R0~R11, P0~
Select from P3, set the corresponding port to "H", turn on the electromagnet S,
Further, if the content of the register is "B" representing "needle selection", the corresponding output port is similarly set to "L" and the electromagnet SL is turned off (OFF). That is, in this example, K and L carriages 13, 20
As the knitting needles 3 travel, regardless of whether the carriage travels in the left or right direction, as shown in FIG. In particular, since it is a setting for controlling power outage, and data on "needle selection presence/absence" is transferred from the MPU in an orderly manner in relation to the running of the knitting needles 3 one pitch at a time.
There is no need for KL carriage discrimination data, and the configuration continues to energize the electromagnet SL while the knitting needle 3 runs for 16 pitches. There is no need to separately determine when the power to the SL will be cut off. Therefore,
The SPU 1 operates in such a way that the electromagnet SL is immediately energized or de-energized based on the transferred data each time the data "with or without needle selection" is transferred from the MPU.

After the SPU1 executes the above-mentioned "needle selection yes/no" control operation, it again enters a check operation with the same timing as above, and the port R13 becomes "L".
Start asking over and over again. In such a "standby mode" check operation, for example,
When "C" data is transferred from MPU,
SPU1 judges this as numerical data representative of "hatch open", immediately enters "display mode", writes "1" as hatch open in the register, and then shifts to the above-mentioned "display" operation. Then, the segment display by the numeral display section 111 is executed again, and immediately after that, the content of the "DN REG" for the number of stages as the "display data" transferred from the MPU is displayed by lighting on the numeral display section 111.

SPU1, which executes each of the above-mentioned controls according to the main flow shown 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 Figure 63, SPU1
After saving the registers of ACC, If it is open, all P ports P0 to P3 and R0 to R11 are set to "H" output, and electromagnets SL0 to SLF
After setting the needle selection state to all energized, and returning to the main flow after register recovery, for example, "H"
In order to notify the MPU that this is a "VIDEO2" signal as a valid interrupt, port R15 is set to "L", and then port O3 is set to "H" to give an external interrupt command to the MPU. . Then, after the time has passed until the MPU confirms this, return ports O3 and R15 to their original values, and then, based on the contents of the register, if the hatch is open, change ports P0 to P3 and R0 to R11 in the same way as above. All outputs are set to "H" and after register recovery, the process returns to the main flow.

MPU and SPU shown in Figures 23 to 26
As is clear from the timing of the external interrupt in step 1, the time when the SPU 1 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 knitting needles 3, and a valid external interrupt command is given from the SPU 1 to the MPU each time. That is, in this example, the needle pulse output related to the knitting needle pitch of the carriage is executed under program control of the processor in place of a carriage position detection circuit consisting of a hardware logic circuit.

Also, carriages 13 and 20 are running to the left.
In either case, when an external interrupt command is given to the MPU from SPU1, or when a valid interrupt command is not given after traveling to the right, if the hatch is open, the knitting needle of the carriage 3, the operation of setting all ports P0 to P3 and R0 to R11 to "H" output is repeated to ensure a state without needle selection.

Next, regarding the control operation of SPU2, FIG.
Explaining according to the flow diagrams of FIGS. 59, 64 to 79, 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 port and outputs "L" from ports P0 to P3, thereby generating pulses. Stabilize the motor 80 in the initially stopped excited state,
At the same time, the error lamp L14 and the LP lamp L17 are kept off, and all of the OL ports O1 to O3 are set to "L" output to ensure the non-operation of the DC motor 86, and the system flag of the internal RAM and the register are Among them, the one that is required is set as the initial reset state. For example, store "0" in the register representing the key-in step order, which will be described later.
Or “Z・REG” for numerical data (Z2 to Z0)
is cleared to "000", and then "B" is stored in the key input permission flag register.

As shown in the register details in Figure 47, the cash register also changes the weights of "1", "2", "4", and "8" to 0, which has a weight of "1", according to the content of each bit. Corresponds to the number keys 110 whose bits are “0” to “9”,
Bit 1 with a weight of "2" corresponds to the step key 113, and bit 2 with a weight of "4" corresponds to the step key 113.
The 3 bits with a weight of 8 are on the left and right keys 114, 115, the step back key 116 represented by the function key, and the start key 11.
7 and reshaping key 118, respectively, and when each bit is "1", key input is permitted;
When the flag is "0", the content of the flag indicating that key input is disabled is stored. Then, each time each of the above keys is operated, the SPU 2 inquires about the contents of the register, which is the key input permission flag, and if the key input is permitted, the key operation at that time is validated and control is performed based on this; It does not respond as an invalid key operation, and the correction key 112 always responds as a valid key operation regardless of the contents of the register.
Therefore, the "B" data stored in the register at the initial stage of the power-on reset is
Only keys 14 and 115 are disabled, and the other keys are enabled.

Note that, like the SPU1 and MPU mentioned above, SPU2 has a configuration in which each output port is automatically set to "H" by power-on reset, so there is no need to specifically set port O5 with a program command, and the operation of electronic buzzer BS It enters a waiting state.

Thereafter, the SPU 2 reversely rotates the DC motor 86 by setting the port O1 to "H" output, and moves the sensor 92 to the left reading waiting position. Even if the time required to return to the left position (200m
After a period of time (seconds) has elapsed, the port O1 is returned to the "L" output, and the port O2 is set to the "H" output and placed in a reverse hold state. That is, when the power is turned on, the sensor 92
The machine always stops at the left reading waiting position and prepares for the subsequent reading run.

Next, SPU2 sets port R7 to "H" output (already at "H" when the power is turned on), and that port signal causes SPU2 to output "NO.
When the MPU is in the ``BUSY'' data transfer state, the MPU can freely check the data, and then enters a ``standby mode'' in which it performs a timing check operation. In other words, the SPU2 is in a relationship where the start commands for various controls are transferred from the MPU as numerical data representing each. Specifically, the MPU transfers data to the SPU2 according to the timing flow shown in Figure 58. Sometimes, the data ``1'' represents ``Hatsuchi open?'', the data ``2'' represents ``card reading,'' the data ``3'' represents ``key SW scan,'' and the data ``reorganize transfer.'' By setting data “4” representing “power-on transfer” and data “6” representing “power-on transfer” to ports R12 to R15 in advance, and setting port O3 to “L” output, SPU2 Check to determine whether this is an "L" signal transfer command.

Then, SPU2 repeats the operation of constantly checking port R8 and waiting for data transfer from MPU in the "standby mode", and if port R
If 8 is “L” input, port R12~
Store the data received via R15 in the register and output port O4 to "L" to end the transfer.
Notify MPU. MPU confirms the completion of this transfer at port R10, outputs data of "F" to ports R12 to R15, and then returns port O3 to "H" again, SPU2 sets port O4 to "H".
64, port R7 is immediately set to the "L" output of "BUSY" and control operation based on the bearing data is started.

For example, the content of the register that is bearing data is "6".
When this happens, this is used as a control start command for "power-on transfer", and then the data transferred from the MPU is transferred to the required amount of internal RAM of SPU2 according to the timing flow shown in Fig. 58, which is similar to the above. Store it in the cash register. That is, in this example, the SPU 2 is in charge of the actual feed control operation of the card 59, and for example, in accordance with various needle selection modes such as double knitting and vertical double knitting, the SPU 2 is in charge of the actual feed control operation of the card 59 as the carriage is reversed. When the MPU determines whether or not to execute the feeding operation, and gives the SPU2 a "card reading command" which is a prefix command for sending back the card, the SPU2 further determines in which direction the card 59 should be sent, etc. Also, when all patterns are selected, the reference position of each repeating pattern is determined.
The configuration is such that the SPU2 makes decisions and notifies the MPU, but since the SPU2 itself cannot protect the underlying data (when the power is turned off), the MPU stores these basic data in external RAM. I'll let it happen. 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-on transfer",
The data sent from the MPU is "DN/REG" for the number of external RAM stages (middle stage), "first stage (1)" and "last stage".
(2),” “Mock left A (3)” and “Mo right A (4)” memory contents and card feeding direction flag contents, SPU2
transfers these data to the internal RAM, "G REG" for the number of stages (middle stage), "H REG" for the first stage, "O REG" for the last stage, register for the card feed direction flag, and "F REG" for the left stage.・REG”, stored in “R・REG” for model right. After completing the "power-on transfer", SPU2 sets port R7 to "NO/BUSY" again.
After setting the output to "H", the process moves to check operation of port R8 and waits for the next data transfer from the MPU.

Furthermore, when the SPU2 transfers the data "2" from the MPU, it operates as a control start command for "card reading", and performs the "card reading" shown in FIG.
Perform control according to the flow. That is, SPU2 first writes right direction data "0" to the sensor movement direction register, sets the built-in timer to 200 msec and starts it, and then sets port O0 to "H" to control sensor 92. Move to the right and check the "CLOCK" signal which is the input signal of port R11.

As is clear from FIG. 34a, for example, immediately after the sensor 92 starts moving forward from the left reading waiting position to the right, "1" corresponding to the "1" pixel area 61 on the card 59 is displayed. Since the "CLOCK" signal of "L" is output until the left end of the transparent window 73a numbered "1", the "CLOCK" signal is outputted repeatedly until the sensor 92 reaches the transparent window 73a number "1". Check whether it is "H". At the same time, SPU2 continues to check whether the timer over (end) flag is set.
If before the “CLOCK” signal changes to “H”,
If 200 msec is counted and the timer over flag is set, the sensor 92 has some kind of failure and has not started running, or the card 59
is not set in the reading mechanism 68.
The signal will remain "L"), immediately clear the card data transfer count register to "0", and then set port O1 to "H" output.
After m seconds have elapsed, the port O2 is set to "H" output to ensure the read waiting state of the sensor 92. Then, the contents of the register are immediately incremented and "0" data is transferred to the MPU each time.

That is, according to the timing flow shown in FIG. 59, SPU2 stores "1" being transferred in the transfer flag register in advance, outputs the transfer data from the register to ports R12 to R15, and sets port O4 to "L". ” output to inform the MPU of the data transfer.
Then, the MPU responds to this, ends the data transfer, and outputs port O3 to "L", so SPU2 confirms the data transfer, sets the register to "0" indicating no transfer, and then outputs "L" to port O3. , ports R12-R1
Outputs "F" data to port 5 and returns port O4 to "H". In response to this, when MPU confirms that port O3 is returned to “H”, SPU2 then increments the register again and sets the “0” data.
Transfer to MPU and repeat this process for a total of 30
Transfer data once. As a result, even in the event of a reading error in which the sensor 92 is out of order or the card 59 is not set, "0" data is transferred to the MPU in place of the "card data" signal.

Next, in order to notify the outside of the reading error, the SPU2 moves to the "2-second buzzer" subroutine shown in FIG.
After making a beep sound for a second (the operation of temporarily outputting "L" from port O5 is repeated for about 2 seconds using the 0 and 1 registers and the built-in timer), the port R is turned on again.
After setting 7 to “H” output of “NO・BUSY”,
It enters a check operation of port R8 and waits for the next data transfer from the MPU.

According to the flowchart in Fig. 65, if there is no read error and the SPU2 detects the "H""CLOCK" signal before the timer measures 200 msec, it then resets the serial empty flag. Then, activate the serial input external clock, clear the register to 0, set the timer to 24ms, and start the timer.
Then, it repeats the operation of checking the empty plug that is set when four "L""CLOCK" signals are input to the serial shift clock terminal, and the operation of checking whether the timer over flag is set. If the empty flag is set first, the 4-bit "card data" signal stored in the serial buffer is transferred to the MPU, the contents of the register are incremented, and then the timer is started again. 24m
Set it to seconds and repeat the same operation. In other words, a 60-bit "card data" signal corresponding to 60 pixel areas 61 is obtained by one forward (rightward) scan of the sensor 92, and this is sent to the MPU in an orderly manner as data of 4 bits each. Forward.

When the SPU 2 completes a total of 15 data transfers due to forward scanning of the sensor 92, the SPU 2 then rewrites the contents of the register to "1", which is the left direction data, and outputs "H" from the port O1 to the sensor 92. 92
Move back to the left side. After that, the operation of incrementing the contents of the register in the same manner as above and
After repeating the data transfer to the MPU and completing 15 data transfers, after 50 msec has elapsed to ensure the return movement of the sensor 92, the port O2 is set to "H" output and held in the read waiting state. do.

If the sensor 92 stops due to some kind of failure while the sensor 92 is moving forward or backward, a 24ms timer flag is set before the serial empty flag is set. , the subsequent data transferred to the MPU is represented by "0", so that a total of 30 data transfers are performed.

The SPU 2 that has executed the "card reading" control according to the flowchart in FIG. 65 then shifts to the "card sending back" control shown in FIG. 66. That is,
For SPU2, on the condition that the contents of "H REG" for the first stage and "O REG" for the last stage are different,
Compare the contents of each register and, for example, if the last row is larger than the first row, write "1" with no upper or lower hand in the comparison register, and conversely, if the first row is larger than the last row, write the upper or lower hand in the same register. Write "0" for the tag. Next, select “G・ for the number of stages (middle stage)
REG" and "H REG" for the first stage are the same, and if they are, and if "0" is stored in the register with no upper and lower hand, the card feed direction flag is In order to store the normal feed data of "1" in the register, increment the contents of "G REG" and add 1, and then perform the one step feed operation of the card 59, the "Card feed" shown in FIG.
Shifting to a subroutine, the pulse motor 80 is controlled. According to the flow in Figure 76, SPU2
First, set port P0 to "H", start driving the pulse motor 80, reset the oil overflow flag, and then set the data "9", which is the content of CF, to TL and TH of the timer counter. (CF
= 9, 10ms) 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 excitation pulse at 10 msec intervals, and also controls the card 5.
Each stage of 9 carries out a continuous feeding operation of 4 steps. Specifically, ports P0, P
After changing the "H" and "L" outputs of the required ones, the timer is set to 10 msec and started, and then the timer over flag is checked.

Then, when the timer of SPU2 clocks 10 msec and the timer over flag is set, the SPU2 outputs "H" to port P1 and starts the timer again for 10 msec.
When the over flag is set after 10 m has passed, port P0 is returned to "L" output, the timer is set to 10 ms, and then started, and another 10 ms has elapsed. If port P1 is also changed to “L” output, the 10m
After a second, the process returns to the flow shown in FIG. 66.

FIG. 40a shows changes in the excitation pulse of the pulse motor 80, which are output changes of the ports P0 and P1 and each inversion signal, which are performed by the above-mentioned "card feed" control, and shows the card feed mechanism of the pulse motor 80. Based on
After 40 milliseconds of the step, the card 59 is advanced by one step in the direction of arrow G in FIG.

SPU2, which has finished the "card feed" control according to the flowchart in FIG. Terminate all of the "return" controls and set port R7 to "NO/BUSY" again.
After setting the output to "H", a check operation is performed on port R8 to wait for the next data transfer from the MPU. However, if "0" data is stored in the register, which is not the beginning of knitting, the contents of "G REG" for the number of rows (middle row) will be changed to "H.
REG" is greater than "1", and if so, the process moves to the "1 second buzzer" subroutine shown in FIG. 75 to notify the end of one unit (vertical direction) of the pattern After making the electronic buzzer BS beep for about 1 second with a length that can be distinguished from the error notification above, the "Card Sending Back" button shown in Figure 68 is pressed.
End control.

Also, if the contents of "G REG" for the number of rows (middle row) match the contents of "H REG" for the first row, and "0" is stored in the register for upper and lower handouts, "0" in the register for card feeding direction flag
After writing the reverse data of ``G.REG'' and decrementing the contents by 1, the process moves to the ``card return'' subroutine of FIG. 77 in order to perform one step return operation of the card 59. That is, SPU2
According to the flowchart in Figure 77, by using the built-in timer, port P1 is outputted to "H", port P0 is outputted to "H", port P1 is outputted to "L", and port P0 is outputted to "L" every 10 msec. '' output to form the excitation pulse variation of the pulse motor 80 shown in FIG. 40b, thereby making one step 10
After a total of 4 steps of 40 m seconds have elapsed, the card 59 is moved back by one step in the direction opposite to the direction of arrow G in FIG. Next, check the contents of the end register, and if the data is "0", which is not the beginning of knitting, the contents of "G REG" for the number of rows (middle row) will be changed to the contents of "H REG" for the first row. Checks if it is "1" smaller than, and only when this is satisfied,
The process moves to the "1 second buzzer" subroutine shown in FIG. 75, and the electronic buzzer BS beeps for about 1 second to notify the end of the trouble as described above.

Also, according to the flow in Figure 66, SPU2
If the contents of "G REG" and "H REG" for the first stage are not equal, then check whether the contents of "G REG" and "O REG" for the last stage are equal, and if not , moreover, if there is a "1" for forward feed in the register, the same operation as above is performed, such as incrementing "G REG" and adding 1, but if there is a "0" for reverse feed in the register, "G After decrementing ``REG'' and subtracting 1, the flow moves to the same ``card return'' flow as described above, and the card 59 is returned one step.

Also, according to the flow in Figure 66, SPU2
If the contents of “G・REG” and “O・REG” for the final stage are equal, write “0” data, which is not the beginning of knitting, to the end register, and then set switch SW4 vertically (“0” in the register “0”). 0" is stored), and if there is a "1" with no top and bottom handouts in the register, the flow shifts to storing "0" data sent backwards in the cash register, and if there is a "1" with no top and bottom handouts in the cash register. If there is a "0" in the register, the flow shifts to storing "1" data of forward feed in the register.
However, if switch SW4 is set to repeat,
After storing the contents of "REG" in "G REG" for the number of stages (middle stage), calculate the difference in the number of stages between "O REG" for the final stage and "H REG" for the first stage, that is, The number of stages required to return the card 59 from the final stage to the first stage is determined and stored in "T.REG".

Then, based on the contents of the register, the SPU 2 returns to the 78th stage in order to perform T-stage reversal if there is no upper and lower hand stitches, and to perform T-stage forwarding if there is a vertical hand plate.
Moving to the "T-stage card feed back" subroutine shown in the figure, in particular, by utilizing the register, at the beginning of the feed back, the pulse motor is set to "9" in the CF register for speed setting, and the pulse motor is run for 10 msec. The excitation pulse is changed every time, and each step is 10 msec, and one step of card feeding and return is executed after a total of 4 steps of 40 msec. Then, as shown in FIG. 89, the contents of the CF register are sequentially added to accelerate the change in excitation of the pulse motor, and the card 59 is moved at once by increasing the excitation change of the pulse motor so that the initial feed speed is reached at the end of the return. To fast-forward or fast-reverse, and to make an electronic buzzer BS sound in the middle of forwarding or reversing. After that, SPU2
Finish the "card sending back" control in the flow shown in Figure 66, set port R7 to "H" output (NO/BUSY) again, perform a check operation on port R8, and start the next data transfer from the MPU. I look forward to it.

Also, in the main flow of Figure 64, the SPU
2 executes the "key SW scan" operation shown in FIGS. 67 to 72 using this as a "key SW scan" control start command when "3" data is transferred from the MPU. That is, first, move to the blow in Figure 67, and first turn on the various switches SW0 and SW2.
Check the contents of contacts ~8 and transfer the ON/OFF data to the MPU.

That is, according to the timing operation of FIG.
The data transfer by the register is performed twice, 4 bits per word, and the SW scan data is transferred to the MPU. In particular, based on the scan data,
When switch SW4 is set vertically, "0" is stored in the 0 register in the internal RAM of SPU2, and "1" is stored when switch SW4 is set to repeat.
When the pattern selection switches SW1 and SW5 are set to 2, "0" is stored in the register, and in other cases, "1" is stored, and this is used as the basis for various subsequent controls of the SPU 2 itself.

Next, according to the key scan flow shown in FIG. 67, SPU2 performs the sixth step when "0" indicating no calculation is stored in the AM register for all calculation steps.
Moving to the flow shown in Figure 8, we check to see if any keys are being operated. Specifically, we set port R4 to "L" output, and first scan the number keys 110 for "4" and "9" at the same time. Then, check whether all the keys are OFF, and if so, that is, if there is no key operation, switch to port R4 and set R3 to "L" output. Then, numeric keys 110 for "3" and "8" and correction key 1
Perform 12 scans at the same time, all of them
If it is OFF, then set port R2 to "L" output, scan the numeric keys 110 "2" and "7", step key 113, and back step key 116 at the same time, and if these are all OFF, output "L" of port R1. L” output, numeric keys 110 for “1” and “6”
Scan the right key 115 and reshape key 118 at the same time, and if they are all OFF, port R
With the "L" output of 0, the number keys 110 of "0" and "5", the left key 114, and the start key 117 are simultaneously scanned. If this is also all OFF, the SPU2 assumes that no key was operated during the key scan at that time, stores the "F" data in the register, transfers the data to the MPU using the same timing operation as above, and then returns to the 64th key scan. Returning to the flowchart in the figure, set port R7 to "H" output of "NO・BUSY", and then do the same port R as above.
Repeat the check operation in step 8. during key scan
The data transferred from SPU2 to MPU is from "0" to
``0'' to ``9'' correspond to the number key ``9'', step key is ``A'', starting key is ``B'', correction key is ``C'', left key and back key are common ``D''", the right key and the reshape key are the common "E", and when there is no key, it is represented by "F".

When the SPU2 detects that at least one key is not OFF in the key scan described above, that is, when a key operation is detected, the SPU2 selects the "L" set number of any of ports R0 to R4, which is the scan port number at that time. For example, if key operation input is confirmed during scanning when port R2 is set to "L" output, "2" is stored in the register.
Store the data in the cash register. Next, it is checked whether any key has been operated, and if it is a key connected to ports K0, K1, or K2, the flow moves to the respective key control flow. If it is not a single key operation, such as when two connected keys are operated at the same time, "F" data without a key is transferred to the MPU, and then "5" is sent to the step order register.
If not stored, check whether the key is turned OFF. Specifically, all keys are scanned at the same time with all ports R0 to R5 set to "L" output, and the key contact contents input through ports K0 to K3 are Check to see if they are all OFF, and check this repeatedly until you are satisfied.

That is, when the SPU 2 confirms the key operation through the key scan, it executes the necessary control based on this, and then checks to see if the key is turned OFF, and only when this is satisfied, returns to the flow in FIG. 64. By shifting to the operation of checking port 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 myself.

In the "key scan" flow shown in FIG. 68, based on the above key scan operation,
When one of the numeric keys 110 from "0" to "4" is operated, the SPU 2 first asks for the contents of bit 0 of the register, checks whether input using the numeric key 110 is permitted, and satisfies this. If so, “Z・
It asks whether the data of the most significant digit Z2 of "REG" is "0". In other words, check whether three-digit numeric data has already been input in "Z・REG", and if it has not been input yet, shift the contents of "Z・REG" one digit at a time towards the upper digits. Then, new key input data, which is the contents of the register, is written in the least significant digit Z0. Then, a flag indicating that a number has been set is stored in the register, and the step key 113 is added to the contents of the register.
After adding the input permission state, by temporarily outputting "L" from port O5, the electronic buzzer is activated by the functions of monostable circuit 176 and transistor 177.
Make the BS ring out loud.

After that, SPU2 transfers the key input data, which is the contents of the register, from the register to the MPU, and then
Ask if it has been turned off and repeat the same control as above. When the SPU 2 confirms the operation of the number keys 110 from "0" to "4" according to the flow shown in FIG. If the content is full of numeric data for all three digits, the key operation is assumed to be invalid, and "F" data without a key is transferred to the MPU, and the key OFF request is started. In this example, when the number of unraveled rows of the knitted fabric is set for reshaping, there is a possibility that "0" is set as the number of unraveled rows. When it is desired to recreate the needle selection pattern, etc., the number data set is "0", so this is recognized as a valid key input operation.

In addition, SPU2 has number keys 1 from "5" to "9".
If the operation of 10 is confirmed, in order to determine the key input data corresponding to each numeric key, add "5" to the register contents as the key scan port number and rewrite it, and then rewrite the key input data from "0" to Control is performed according to the same flow as in "4".

When the operation of the step key 113 is confirmed from the contents of the register according to the key scan flow in FIG. For example, if the content of the step order register is step "0" and the register has a flag of "1" stored,
The operation of the step key 113 at that time is disabled, the "F" data without a key is transferred to the MPU without sounding the electronic buzzer BS, and then the key OFF request is started. However, when "0" is stored in the register with no numeral flag,
Write "0" indicating no operation in the double-pressing prevention register at the beginning of the game, and increment the contents of the register to create a "1" step state. Then, move to point (16) in the flow in Figure 68,
Rewrite the contents of the cash register to "3" and press number key 11
0 and step key 113 (however, the correction key 112 is always OK to input. The same applies hereafter), write "0" for the no numeral flag in the register, and press "Z REG". After clearing to "000" and sounding the electronic buzzer BS, the data of "A" representing the step key is transferred to the MPU, and then it starts asking for the key OFF.

Further, when the SPU 2 confirms that the step key 113 is a valid operation according to the flowchart in FIG. 69,
When the content of the register is step ``1'', if there is a ``1'' in the register with a number set, the process moves to the ``0 check'' flow of the ``check'' subroutine shown in FIG.・By checking the numeric data that is the contents of ``REG'', only when this is ``0'', outputs ``H'' from port P3, lights up the error lamp L14, and writes ``0'' to the register. Store and correct key 11
After allowing the input of only 2, move to the "2 seconds buzzer" subroutine in Figure 74, make the electronic buzzer BS beep for about 2 seconds, then transfer "F" data without a key to the MPU and turn the key OFF. Start asking. If there is no numeric error, write the numeric data that is the contents of "Z・REG" at that time to "H・REG" for the first stage, increment the contents of the register and rewrite it to step "2". With,
Rewrite the contents of the cash register to "3" and set the state to allow input of the number keys 110 and step keys 113, then clear "Z・REG" to "000" and set "0" with no number in the cash register. After writing and sounding the electronic buzzer BS, it transfers the "A" data representing the step key to the MPU, and then starts asking for the key OFF. However, if there is a "0" without a number in the register, the operation immediately shifts to incrementing the contents of the register.

In addition, when the SPU 2 confirms that the step key 113 is a valid operation and the contents of the register is step "2", if there is a "1" with a number in the register, the same "0 check" as above is performed. Only when the following is satisfied, the numeric data that is the contents of "Z・REG" at that time is written to the final stage "O・REG", and then the contents of the register are incremented and rewritten to step "3". However, if there is a "0" without a number in the register, the operation will immediately rewrite the contents of the register to "3", skipping the "0 check" and writing operations to "O・REG". and transition.

In addition, when the SPU 2 confirms that the step key 113 is a valid operation, and the contents of the register is step "3", if there is a "1" with a number in the register, the "check" button in FIG. Move to the "60 check" flow of the subroutine and save the data "60" stored in "T・REG" as a temporary register and "Z・REG" at that time.
Compare it with the digit data stored in ``Z・
Port R only if the contents of “REG” exceed “60” and the numeric data is “00”.
3 to "H" output, the error lamp L14 is lit, "0" is stored in the register, and only the correction key 112 is allowed to be input.
Move to the "2 seconds buzzer" subroutine shown in the figure, make the electronic buzzer BS beep for about 2 seconds, and then
Transfer "F" data without key to MPU and key
OFF starts asking. If it is confirmed that there is no numeric error, the "Z・REG" at that time
Writes the number data which is the contents of ``F・REG'' for the model left, increments the contents of the register, and moves on to the operation of rewriting to step ``4''. However, if there is a "0" with no number in the register, the operation of writing to "60 check" and "F.REG" is omitted, and the operation immediately shifts to incrementing the contents of the register.

In addition, when the SPU 2 confirms that the step key 113 has been operated validly and the contents of the register is step "4", if there is a "1" with a number in the register, the same "60 check" as above is performed. As long as the following is satisfied, write the numeric data that is the contents of "Z・REG" at that time to "R・REG" for the model right,
After that, the contents of the register are incremented and rewritten to step "5", and "6" is stored in the register, and the step key 113 and left/right key 11 are pressed.
Enable input only to 4,115, set port P2 to "H" output, turn on LR lamp L17,
Clear "Z・REG" to "000", store "0" with no digit in the register, make the electronic buzzer BS sound, and then transfer "A" data representing the step key to the MPU. do. Next, since the contents of the register after the above addition are step "5", the pattern selection switches SW1 and SW5 are set to "Full pattern".
If it is not, it will immediately start asking you to turn off the key. However, if it is set to "All", for example, the AM register for the calculation step will be set as a preparatory step for the "All" calculation. Write "1" with calculation to , return port P2 to "L" output, turn off LR lamp L17, and then start asking for key OFF. If there is a ``0'' without a number in the register, the operation will skip the ``60 check'' and write operations to ``R・REG'' and immediately move to the operation of rewriting the contents of the register to ``5''.
Perform the same general checks as above.

In addition, when the SPU 2 confirms that the step key 113 is a valid operation, if the contents of the register are one of step "5", "6", "A", and "B",
If there is a ``1'' with a number in the register, the process moves to the ``100 check'' flow of the ``Check'' subroutine in Figure 73, and the number data that is the content of ``Z・REG'' is not larger than ``100''. or "000", and if these are satisfied, add 1 to the register step contents,
Proceed to step states "6", "7", "B", and "C", store "6" in "B" register, and LR lamp L1
7, clear "Z・REG" to "000", store "0" with no digit in the register, sound the electronic buzzer BS, and press "A" representing the step key on the MPU. ”Transfer data. However, if there is a "0" without a number in the cash register, "R.
``REG'' and immediately shifts to incrementing the contents of the register.

Furthermore, when the SPU 2 confirms that the step key 113 is a valid operation and the register contents are step "7", it turns off the LR lamp L17 and then selects the pattern selection switch from the contents of the 1 register.
Check the set positions of SW1 and SW5, and if ``2 is possible'', increment the contents of the register and rewrite it to step ``8'' only if the same ``100 check'' as above is satisfied. ``3''
However, if it is not "2 moyo", that is, "all moyo" or "1 moyo", the states of steps "8" to "C" are unnecessary. Therefore, after the same "100 check" as above, the contents of the register are advanced to the final "D" step state, "B" is stored in the register, and "Z.
Clear "REG" to "000", store "0" with no digit in the register, sound the electronic buzzer BS, and transfer "A" data representing the step key to the MPU.

In addition, when the SPU 2 confirms that the step key 113 is a valid operation and the contents of the register are either step "8" or "9", the SPU 2 performs the same "60 check" as described above and then checks the contents of the register. is incremented to advance to the step state of "9" and "A", and if the contents of the register after the addition are "9", store "3" in the register, and similarly, if the contents of the register are "A" Then, the operation moves to storing "6" in the register.

In addition, when the SPU2 confirms that the step key 113 is a valid operation and the content of the register is step "C", it turns off the LR lamp L17, moves to the "100 check" flow, and performs the same "100 check" flow as described above. Check the numeric data of ``Z・REG'', and if this is satisfied, advance the contents of the register to the final ``D'' step state and place ``B'' in the register.
, clear "Z・REG" to "000", store "0" with no digit in the register, sound the electronic buzzer BS, and send "A" data representing the step key to the MPU. transfer.

In addition, when the SPU 2 confirms that the step key 113 is a valid operation, if the content of the register is step "D", or if there is a number "1" in the register, it responds to the key operation at that time. without sounding the electronic buzzer BS,
Transfer "F" data without key to MPU. However, if there is a "0" without a number in the register, the contents of the register are returned to the initial "0" step state,
The operation moves to storing B in the cash register.

According to the key scan flow shown in FIG. 68, when the SPU 2 confirms that either the left or right key 114 or 115 is a valid operation based on the contents of bit 2 of the register, it changes the contents of the register to "1". After allowing input only on the numeric key 110, turning off the LR lamp L17 and sounding the electronic buzzer BS, the left key 114 inputs the representative "D" data, and the right key 115 inputs the representative "D" data. It transfers the representative "E" data to the MPU, and then starts asking for key OFF.

Also, according to the flow in Figure 70, SPU2:
When it is confirmed that the start key 117 is a valid operation based on the contents of the register and the contents of bit 3 of the register,
First, check the contents of the double-press prevention register, and even if there is already a "1" indicating operation, or "0" indicating no operation, if there is a "1" in the register with a number set. , does not respond to the operation of the start key 117, does not sound the electronic buzzer BS, and transfers the keyless data "F" to the MPU. However, if there is a "0" with no operation in the register and a "0" with no digits in the register, the stock start control operation is immediately executed according to the flowchart in Figure 70, and the contents of "H REG" are The card feeding stage number of the "T stage" calculated by adding "13" to the stage value of the first stage of the barrel is stored in "T REG", and the process moves to the "T stage card feeding back" subroutine shown in Fig. 78. Executes "T stage" card feeding. That is, when the start key 117 is operated, the card 59 is always set in advance at a position where the set line 67 is aligned with the upper edge of the insertion section 140, for example, in the "1" stage. To make the column of pixel area 61 correspond to reading position J (FIGS. 5 and 17)
Since it is necessary to feed the card in 14 stages, "13" is added to the contents of "H REG" for the first stage, and the column of the pixel area 61 of the first stage selected at that time is T.
By feeding the stage card, it matches the reading position J corresponding to the sensor 92.

Next, after feeding the T-stage card, the contents of "H・REG" for the first stage are transferred to "G・REG" for the number of stages (middle stage).
REG", compare the contents of "H REG" for the first stage and "O REG" for the last stage, and write "O.
If "REG" is larger, write "1" data for forward feed in the card feed direction register, and conversely, if "H REG" is larger, write "0" data for reverse feed in the register, Store "1" indicating operation in the double-press prevention register to prevent the above-mentioned start-of-load control from being repeated more than once by mistake, and also store "1" at the start of re-pressing in the register after the push is over. ” data, write the initial step status “0” to the register, and then turn on the electronic buzzer.
Sounds the BS and transfers "B" data representing the starting key to the MPU.

Further, according to the flowchart in FIG. 70, when the SPU 2 confirms that the step return key 116 is a valid operation based on the contents of the register and the contents of bit 3 of the register, for example, "0" with no digit is stored in the register. , store "0" in the cash register to enable the starting key again, and return the "T stage" card calculated by adding "13" to the contents of "G REG" for the number of stages (middle stage). Write the number of stages in "T・REG" and move to the 7th
The "T-stage card send back" subroutine in Figure 8 returns the "T-stage" card, stores the "000" data of the card removed in "R・REG" for the number of stages (middle stage), and then starts the cash register. After returning the step state to "0" and sounding the electronic buzzer BS,
Transfer "D" data representing the step return key to the MPU. That is, when the step return key 116 is operated without setting a number, the card 59 is returned at once to a position where the set line 67 of the card 59 matches the upper edge of the insertion section 140, contrary to the position at the beginning of the play. This is a so-called set state where the card is removed.

In addition, in response to the operation of the step back key 116, if the register shows "1" with a number to be set, the SPU 2 first moves to the "Z-check" flow of the "check" subroutine shown in FIG. In particular, by utilizing the calculation "L REG", the number data that is the content of "Z REG", including the contents of "H REG" for the first stage and "O REG" for the last stage, can be changed. Check if the stage value is between 1 and 2, and if there is an unsatisfactory setting error, store "0" in the register and turn on the error lamp L1.
4 is lit, the electronic buzzer BS beeps for 2 seconds, and the "F" data without the MPU key is transferred, but if there is no setting error, then "G REG" for the number of stages (middle stage). If it is "0" indicating that the card is removed based on the contents of "Z.
“T stage” obtained by adding “13” to the contents of “REG”
, send the card, change the contents of "Z・REG" to "D・REG" for the number of rows (middle row), and then perform the operation to return "0" to "0" of the cash register in the same manner as above without setting the number.・Clear "REG" to "000",
Store “0” without a digit in the cash register and turn on the electronic buzzer.
After sounding the BS, transmit "D" to the MPU. Also, if the content of "G REG" for the number of rows (middle row) is "0" or less and no card is 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. is the pixel area 61 that matches the contents of “Z・REG” at that time.
The T stage of the card 59 is sent back so that the number of stages corresponds to the reading position J.
If the number data that is the content of "REG" is larger than "G・REG", the card is returned by T stages which is the difference between them, and vice versa, the card is sent by T stages which is the difference between them. Execute and change the number data that is the contents of "Z・REG" to "D・
REG" and perform the same operation as above to return the register to "0".

As described above, when the content of the register is step "0" or "D" and the start key 117 is operated effectively without setting a number, the column of the pixel area 61 at the start stage is read. When the card 59 is advanced in one step so that it matches the position J, and the step return key 116 is effectively operated without setting a number, the card set line 67 is moved to the card set position where it matches the upper edge of the operating section 140. , the card 59 is moved back in one step, but especially if the step back key 116 is operated effectively after the number has been set, the column of pixel area 61 that matches the set number data corresponds to the reading position J. Place the card 59 in an arbitrary number of stages by moving the card 59 forward or backward.
It is possible to send back.

According to the flowchart in FIG. 70, when the SPU 2 confirms the operation of the rework key 118 from the contents of the register, if there is "0" without a number in the register, it responds to the operation of the rework key 118 at that time. The keyless data "F" is transferred to the MPU without the electronic buzzer BS sounding. However, if there is a ``1'' with a number in the register, first move to the ``G-check'' flow of the ``check'' subroutine shown in Figure 73, and especially utilize the calculation ``L REG'' to find the number of stages ( Check whether the content of "G REG" for the middle stage) is a stage value between them, including the contents of "H REG" for the first stage and "O REG" for the last stage, and if it is not satisfied. For example, the card set status at that time is determined to be non-conforming, and "0" is written in the register, the error lamp L14 is turned on, and the electronic buzzer BS beeps for about 2 seconds. If “G check” is satisfied, then set “Z・REG” to “000”
, store "0" with no number in the register, write step status "0" in the register, sound the electronic buzzer BS, and send "E" data representing the rework key to the MPU. transfer. After that, SPU2 waits for data transfer from MPU,
Starts a timing check operation for port R3.
That is, in this example, when reshaping, for example, K
When knitting using Carriage 13 alone, the number of rows in which the knitted fabric is unraveled is set, and the L
In knitting where the carriage 20 selects needles and transfers stitches, set the number of L carriage runs to the return stage minus one stage and then operate the reshaping key 118. card 5
The "number of return stages" of 9 is determined by the MPU, and it is immediately sent along with the card feeding direction data after returning.
The relationship is that it is transferred from MPU to SPU2.

Therefore, after SPU2 transfers the "E" data representing the rework key with a set number according to the flowchart in FIG. 70, it shifts to the flowchart in FIG. Waiting for "Repair transfer", data "4" representing this is transferred, and the process moves to the flow shown in FIG. 72 to execute rework control. In other words, the data for the number of stages (middle stage) that is the "number of stages to return" is temporarily written to "L REG", the card feed direction data is stored in the register, and then the data for the number of stages (middle stage) before resetting (returning) is written (R・REG”
and the contents of "L・REG" which is the number of stages data after return, and calculate the number of "T steps" required to actually send back the card 59 as "T・REG".
For example, if the number of stages (middle stage) value after returning is smaller, return the "T stage" card,
If the size is too large, feed the card in the "T stage",
Then it starts asking for key OFF.

In FIG. 68, when the SPU 2 confirms the operation of the correction key 112 based on the contents of the register, it turns off the error lamp L14, and if the step contents "0" or "D" are present in the register, the SPU 2 displays "B" in the register. ", and the contents of the register are "1",
If the value is ``2'', ``3'', ``4'', ``8'', or ``9'', ``3'' is stored in the register, and the contents of the register are ``5'', ``6'', or ``7''. ”, “A”, “B”, “C”
In this case, after setting the contents of the cash register to "6", if it is any of these, then "Z.
Clear "REG" to "000" and store "0" with no digit in the register, especially in step "5" above.
Only when "6", "7", "A", "B", "C"
Turn on the LR lamp L17 and then turn on the electronic buzzer.
Sounds the BS and transfers "C" data representing the correction key to the MPU.

That is, in response to the operation of the correction key 112, the SPU 2 returns to the initial state at the current step, and the numeric value display section 111 displays "0" and is reset to no numeric value. ”,
After the left and right keys 114 and 115 are operated such as "6", "7", "A", "B", and "C",
The LR lamp L17 is turned on again to enable key-in again and to reset the number setting.

In response to the operation of the step key 113, the SPU 2, which advances control according to the scan flow shown in FIGS. 67 to 72, increments the step order register and shifts to the step state in which 1 is added. The key input permission, which is the flag content, can be changed in various ways. For example, if the register step contents are "5", "6", "7", "A", "B"
”,
When "C" is selected, the numeric keys 110 function effectively only after the left and right keys 114 and 115 are operated, and after the left and right keys 114 and 115 are operated, the step keys only function after the next number is set. 113 from functioning effectively.
Regarding the left and right keys 114 and 115, the contents of the register are "5", "6", "7", "A", "B",
It functions effectively only when "C" is selected and "0" with no digit is stored in the cash register. It is designed to function effectively only when the content is "0" or "D".

At times, when the step key 113 is operated in a step state where the contents of the register are "4" according to the key scan flow of FIG. 68, the contents of the register are rewritten to "5".
In particular, when the pattern selection switches SW1 and SW5 are set to "all patterns", data "1" indicating calculation is written in the AM register for all patterns calculation step. Therefore, based on the key scan command for data "3" which is then transferred from the MPU, scan control in the flow shown in FIG. 67 is carried out.
Since the content of the AM register is "1" with calculation after the SW scan, SPU2 does not move to point (28) of the flow in Figure 68, but simply follows the flow in Figure 67. Proceed with control of standard calculations, etc.

In other words, in this example, when all the patterns are selected, the "first stage", "last stage", "model left A", and "model right A" are stored in each memory even if the operator does not specify it. By inputting the corresponding data, the center of the information effective width (pattern width) of pattern A can be aligned with the center of the needle bed, and a repeated knitting pattern can be realized over all the needles of the needle bed. Then, set the reference position and needle selection range.
SPU2 automatically calculates "Basic A", "Selection A",
This is a configuration in which data to be written to the "Selection A" memory is transferred to the MPU.

According to the calculation transfer flow shown in Fig. 67, SPU2 first transfers the data “D” representing the left key so as to transfer the data to be written to “base A(5)”.
After transferring to the MPU, in order to determine the reference position of the entire pattern, compare the contents of “F・REG” and “R・REG” for the pattern right, and compare the data of their difference (pattern width W
-1) to "T・REG", and then from the contact contents of the horizontal multiplication switch SW0, for example, if there is horizontal multiplication, "pattern width W" data is added to the contents of "T・REG" by 1 to "N・Write to “REG”. In addition, if there is no horizontal multiplication, the data (pattern width W-1) that is the content of "T REG" is divided into two equal parts (W-1/2 =
x) When the "x" data obtained cannot be divided into two equal parts (W-1/2=x...1), write "x+1" data into "N・REG". Then, following the "D" data representing the previous left key, "N.BEG" is transferred so that the content of "N.REG" after the calculation is transferred to the MPU as the left reference position data. The contents of "N1" are transferred to the MPU as numerical data "0" to "9" which are replaced by numerical keys, and then the contents of "N0" are also transferred to the MPU. That is, as illustrated in Fig. 90, if "Momo A" with a pattern width (number of stitches) that cannot be divided into two equal parts at the center of the needle bed is selected, the number 1 knitting needle on the right side is always used as the center reference. Even if there is horizontal doubling as shown in Fig. 55, the reference position is set so that the center of the horizontal doubling A matches the needle bed center "0". and transfers it to the MPU.

After that, SPU2 follows the flow in Figure 67,
In particular, based on incrementing the contents of the AM register every time key data is transferred, all needle selection range data is transferred to the MPU, and specifically,
In order to be able to select all 200 knitting needles 3 on the needle bed, the data for number 100 on the left should be written in the "Selection Left A (6)" memo and the data on the "Right Selection A (7)" memo. should be right
Transfer the data of number 100 to the MPU in order according to the data representing the number keys and step keys.

At the end of the transfer, the content of the AM register is "E", so it is returned to the initial "0" with no calculation, and the register is set to "D" at the end of key input.
Proceed to the step state, store "B" in the register, then press "D" representing the last step key to be transferred.
Transfer data to MPU and start asking for key OFF.

Sometimes, according to the flow in Figure 64, SPU2
When "1" data is transferred from the MPU, this is operated as a "hatch open?" request command, and the process moves to the flow shown in FIG. 71 to proceed with "hatch scan" control. That is, at the beginning port R
Check the input status of 9 and turn micro switch 1.
The open/closed state of the hatch 120 is detected from the ON/OFF contents of the hatch 120. For example, if the hatch is open, first write "0" before calculation to the calculation flag 1 register for all calculations, and then indicate whether the hatch is open or not. After transferring the "E" data representing YES to the MPU, return to the main flow in Figure 64 again.
Waits for data transfer from MPU.

However, if the hatch 120 is in the closed position and the hatch is detected as closed, the "G.
REG", and the stage number (middle stage) value that is the content is the stage number between them including the contents of "H REG" for the first stage and "O REG" for the final stage. and if you are not satisfied,
Hutch 1 in such a card set mismatch condition.
In order to notify the operator that it is not a good idea for 20 to be closed and formation to be carried out, the error lamp L14 is turned on, and the electronic buzzer BS is made to intermittently make a beeping sound. Repeat until hatch 120 is released. Then, as the hatch 120 is opened, the error lamp L14 is immediately turned off and the electronic buzzer BS is activated.
Stops the ringing and transfers the hatch open yes "E" data to the MPU.

If the above "G REG" check is satisfied, then check from the input state of port R10 whether the pattern selection switches SW1 and SW5 are set to "Full pattern", and if not, check In other words, if it is set to "1" or "2", immediately turn off the LR lamp L17 and error lamp L14, clear "Z・REG" to "000", and repeat twice. Store "0" in the push prevention register, step order register, and number flag register, write "B" in the register, and then transfer "0" data representing hatch open/no to the MPU. .

In addition, even if "All" is selected, if "0" data indicating that the previous hatch status is open is stored in the 1st register, the contents of the step order register The step state is advanced and changed to step state "4", which is suitable for calculation of all reference positions, etc., and after the step correction, the process moves to the flow shown in FIG. 67, and the same reference calculation as described above is executed. That is, in this example, the hatch 12
The pattern selection switch is always activated when 0 is closed.
The set positions of SW1 and SW5 are detected, and if they are set to "all", SPU2 automatically calculates their reference positions, etc.
It is related to transferring to MPU.

According to the flowchart in FIG. 71, SPU2 initially
Until all calculations are completed, transfer Hatsuchi Open Yes's "E" data, then
Waiting for the next data transfer from the MPU, for example, if "1" data, which is a request for "Hatsuchi open?", is transferred, "E" data is sent each time.
If the "3" data of the "key SW scan" command is transferred to the MPU, the "SW scan" control similar to the above is executed at the beginning.
Based on the contents of the 0 register, "0" before step correction is stored first, so "0" without a digit is stored in the register in advance, and step key input OK/K is stored in bit 1 of the register. After securing the preparation state where "1" is written in the register, repeat the increment operation of the register and the data transfer of "D" representing the step key, and change the step to the state where step "4" is stored in the register. let After the step correction, a ``1'' indicating that the correction has been performed is stored in the 0 register, and a ``1'' indicating that the entire calculation has been performed is written in the AM register. Therefore, the subsequent
6th based on key SW scan command from MPU
SPU2 moving to point (25) in the flow in Figure 7,
Since "1" is stored in the AM register,
It performs control such as calculation of the reference position of all the objects as described above, and transfers data to the MPU. and,
At the end, the 0 register shows "0" before step correction.
is written to secure a waiting state for the next calculation control, and furthermore, ``1'' after the calculation is stored in the 1 register so that the calculation flow is not repeated when the hatch is closed. That is, when the first "1" data is transferred from the MPU after completing the above calculation, "1" is placed in the register according to the flowchart in Figure 71.
is stored, the process immediately proceeds to normal hatch-close control and transfers hatch-open/no data "0" to the MPU, without proceeding directly to the step correction flow.

The SPU 2, which carries out each of the above-mentioned controls according to the flowcharts shown in FIGS. 64 to 78, immediately receives an "L" external interrupt command to its terminal, that is, when the MPU outputs "L" from port O4. Exiting from the main flow, executing interrupt control according to the flow shown in Fig. 78, and while the MPU outputs port O4 to "L", port R constituting the data byline
12 to R15 as "F" data, the bus line is opened so that the MPU can use it freely, and this allows data transfer from MPU to SPU1 even during data transfer from SPU2 to MPU. . Then, as the MPU returns the port O4 to the "H" output, the SPU2 determines that if there is a "1" in the register indicating that the data is being transferred, that is, the data is being transferred in accordance with the timing operation shown in FIG. If the data transferred at that time is transferred to port R1 again.
2 to R15 and returns to the main flow after register recovery.

Next, the control operation of the MPU will be explained according to the flowcharts shown in FIGS. 80 to 87. First, in FIG. Start, first set ports O0 and O1 to “L”
As output, the left indicator lamp L15 and right indicator lamp L16 remain off, and the necessary system flags (Y address 5), which are the contents of the "flag register" in the internal RAM, are reset to initial "0". In addition, the external RAM step memos ``Start (1)'', ``Start (2)'', ``Model A (3)'', and ``Model A
(4)", "Model left B(8)", "Model right B(9)", memo and number of rows "DN/REG", and "Clear(D)" address part for left/right distinction (A0~7→D '0' to the address)
At the same time as writing the data, "000" data is stored in the "clear (D)" address part.

The MPU then reads the external RAM's "flag memo"
After reading the contents of and transferring them to the address part (Y address 0 to 4) of the "flag register" in the internal RAM, transfer "6" data to SPU2 and perform "power-on transfer", and then write the data in the external RAM. The card feed direction flag is part of the internal RAM's "flag register," including the memory contents of "DN REG" for the number of stages (middle stage), "first stage (1)" and "last stage (2)". The memory contents of "Model A(3)" and "Model A(4)" are transferred to the SPU 2 according to the timing operation shown in FIG. 58. After that, the MPU sets the hatch flag to ``1'' (open) as the initial hatch opening operation, and follows the timing operation shown in Figure 57.
After transferring the hatch open "C" data to SPU1, write the initial data "0" step contents to the STEP/NO register (hereinafter referred to as SN register) that stores the step status, and then write the step contents of "0" as initial data to the contents of the SN register. The matching "0" data is output to the parallel output port P, the lamp L0 is turned on by the action of the decoder circuit 172, and the step memo "0" data (middle stage) which also matches the contents of the SN register (DN/
FEG), transfer it to SPU1, display the segment on number display section 111, and
Set the numeral flag to "0" without a numeral, and set it to "D.
Clear "REG" to "000".

After that, the MPU follows the flow in Figure 80.
By transferring "3" data to SPU2, "key"
Based on this, it receives the "SW data" and "key-in data" transferred from the SPU 2, and executes various key scan controls in response to the transferred data. Next, by transmitting "1" data to SPU2, the open/closed status of hatch 120 is inquired, and if "E" data indicating hatch open yes is transmitted from SPU2, "data input mode" is continued. Then, the "3" data is transferred to the SPU2 again, thereby repeating the "key SW scan" control. When the hatch 120 is newly opened from the closed state, since the hatch flag has been "0" indicating "closed" until then,
The process moves to the initial hatch opening operation in which this is rewritten to ``1'' for hatch opening, and after securing the same step state ``0'' as described above, the ``key SW scan'' control is proceeded.

That is, while the hatch 120 is open, the MPU, which operates according to the main flow shown in FIG. If not, the "data input mode" is continued; if it is, the "data input mode" is exited and the "composition mode" is entered.

According to the flowchart in FIG. 80, the MPU in "organization mode" stores "D" in the SN register, lights up the OK lamp L13 that matches the contents, and performs data set (DS), data change ( The operation of checking whether the contents of each flag (DC) and card reading (CR) are "1" and the operation of asking the SPU 2 about the hatch status are repeated. and,
In particular, before asking SPU2 about the hatch status, SPU2 inputs the signal applied to the serial input terminal SI in synchronization with the internal clock.
Check whether it is in the "NO/BUSY" state that can accept data transfer from the MPU, and if it is "BUSY", the above
Check the DC, CR, DS flags and
Repeat the operation of checking whether SPU2 is "BUSY".

That is, while the hatch 120 is closed, the MPU that operates according to the main flow shown in FIG.
The configuration is such that the key SW scan control is not executed in the "composition mode", and only the OK lamp L13 is lit to display the composition mode. and,
At that time, it asks if the hatch 120 has been opened, and if not, continues the "composition mode" and performs the above-mentioned check operations, etc., and especially only when the hatch 120 is newly closed. Since the hatch flag is "1" for "open", this is rewritten to "0" for hatch closed, and after transferring the "D" data for hatch closed to SPU1, each control of the "composition mode" mentioned above is performed. Repeat. In addition, when the hatch 120 is closed, the OK lamp L13 lights up to indicate that the data entry is completed and the formation is OK, and the hatch 1 is newly opened.
When the hatch 20 is opened, the lamp L0 lights up to display the initial state of data input.Moreover, since the hatch 120 is made of a transparent or translucent material, the hatch 120 can be closed. Even in this state, the lighting of the OK lamp L13 can be confirmed from the outside, and one or more lamps L are always lit regardless of whether the hatch 120 is open or closed.
It can also be used as a so-called power pilot lamp.

First, the details of the key scan control will be explained according to the flowcharts of FIGS. 81 to 83.
MPU is the "SW data" transferred from SPU2
is stored in the SW register of the internal RAM, and "key-in data" is also stored in the key-in register, and various key scan controls are executed based on each data.
For example, if key-in data of "0" to "9" corresponding to the numeric keys 110 of "0" to "9" is transferred from the SPU 2 according to the flowchart of FIG. 81, the MPU According to
If there is, change it to “1” with a numeral, and change it to “D′・
REG" to "000", then select "a" from the key-in data "0" to "9" at that time.
is written to the first digit D0, the content of “D′・REG” is set to “00a”, this is transferred to SPU1, and that SPU
The number display section 111 is controlled by the display control of 1.
The key scan control is ended by displaying "a" as a segment.

However, if the numeral flag is "1" with a numeral, it means that the numeral data has already been stored in "D'REG", and by shifting this up, the contents of D1 are transferred to D2 and D0 The contents of D1
After moving the key-in data at that time to D0
and write the subsequent “D′・REG” contents to SPU1
, and the number display section 111 lights up the display.

Also, when key-in data "A" is transferred according to the flow in Figure 81, the MPU uses this as a representative step key and moves to the flow in Figure 82, and if "D" is in the SN register. if there is,
Change it to "0" and light up the step lamp L0 that matches the content, and call the content of "DN REG" for the step memo number of stages that matches the content of the SN register to "D REG" (D3 to D0). , among them, transfer the contents of "D'REG" (D2 to D0) to SPU1 according to the timing operation shown in Fig. 57, reset the numeric flag to "0", and then transfer the contents of left and right that match the contents of D3. Lighting check control of display lamps L15 and L16 is carried out. Specifically, if D3 has "1" of the left data, port O0 is outputted to "H" to light the left display lamp L15, and D3 is set to "1" of the right data. 2”, output port O1 to “H”, light up the right indicator lamp L16, and set D3 to “0”.
If there is data, both ports O0 and O1 remain at "L" output, both lamps L15 and L16 remain off, and then D3 is cleared to "0" and the key scan control is ended.

Also, according to the flowchart in Fig. 82, the numeric value flag is set to ``1'', and the SN register contains step contents ``1'', ``2'', ``3'', ``5'', ``6'', etc. "8"
,
If there is either "A" or "B", write the contents of "D・REG" to "E・REG" in advance, and also write it in the step memo that matches the contents of the SN register, for example, the step contents " 1”, then “first stage”
(1)", and if it is "3", write it in the "Mosa A(3)" memo. However, the contents of the SN register are "4" and "9".
If it is either, compare "E′・REG", which is the content of the step memo one step before, with the content of "D′・REG" at that time, and find "D′・REG".
If “REG” is larger, leave it as is, but if it is smaller, write the contents of “D′・REG” in one step memo, and write the contents of “E′・REG” in the step memo that matches the step at that time. . For example, when the step content of the SN register is "4", before writing the number data that is the content of "D'・REG" at that time to the "Model A (4)" memo, write it in advance. Check whether the data is larger than the content of the "Model A (3)" memo, and if not, correct it by assuming that the key-ins were keyed in in the left and right order on Model Left and Model Right, and ” to the “Model A(3)” memo, and write the content of “E′・REG” that matches the content of the previous “Model A(3)” memo to “Model A(4)”. Write. Similarly, when the step content is "9", corrections are made if necessary for the "Model B(9)" and "Model Left B(8)" memos. Also, if the content of the SN register is either "7" or "C", the content of the step memo one step before that is "E.
REG” and the contents of “D・REG” at that time, and especially by referring to the left and right data of E3 and D3, “D・REG” is the needle located on the right side on the needle bed. If it is number data, leave it as is, but if it is needle number data located on the left side, write the contents of "D・REG" in the step memo of the previous step, and write the contents of "E・REG" in the step memo at that time. Write in the step memo that matches. For example, when the step content of the SN register is "7", before writing the left/right distinction and number data of "D REG" to the "Selection A (7)" memo, write the written data in advance. Check whether the needle number is located on the right side of the needle bed based on the contents of the "Select Left A (6)" memo.
If not, perform correction as if the keys were entered in the opposite order at the left and right ends of the needle selection range,
Write the contents of “D・REG” in the “Selection A(6)” memo, and write the contents of “E・REG” that match the contents of the previous “Selection A(6)” memo to )”. Similarly, when the step content is "C", corrections are made if necessary for the "Right selection B(C)" and "Left selection B(B)" memos.

Next, the MPU executes the SW according to the flow in Figure 82.
If the pattern selection switches SW1 and SW5 are set to ``2 too'' based on the contents of the register, advance to the step state in which the contents of the SN register are added by 1, and then
Light up the step lamp L that matches the contents of the SN register, call up the stored data of the step memo that also matches the contents of the SN register, write it to "D・REG", and transfer the contents of "D'・REG" to SPU1. Then, reset the numeric flag to ``0'' (no digit), check the lighting of the left and right display lamps L15 and 16 that match the contents of D3, and then clear D3 to ``0'' and start the key scan. End control. However, from the contents of the SW register, “2
If "Momo" is not set, if the contents of the SN register are any of steps "0" to "6", add 1 to the contents of the SN register as in the case of "2 moyo" above. However, if
If the content of the SN register is "7", this is set as the end of data input, the content of the SN register is advanced to step state "D", the OK lamp L13, which is the step lamp, is lit, and the SPU1 is sent to "Clear". (D)" The contents of "000" in the memo are transferred so that "0" is displayed on the number display section 11.

Also, according to the flowchart in Figure 81, when the MPU transfers the "A" data representing the step key, if the numeric flag has "0" without a numeric value, the SN register at that time. By recalling the contents of a step memo that matches the contents to "D REG" in advance, and then proceeding with the same operation as with the above setting, the contents of the previously recalled "D REG" can be read as a step memo again. The key-in data, which is the content of each step memo, is stored. In addition, when key-in data "B" is transferred from SPU2 according to the flowchart in Figure 81, the MPU assumes that this represents the starting key and moves to the flowchart in Figure 82.
Compare the contents of the “(1)” memo and the “final stage (2)” memo,
If the "first stage (1)" is larger, the card feeding direction flag is set to "1" for reverse feeding, and if the "last stage (2)" is larger, the card feeding direction flag is also set. Set to "0" for forward feed. Next, in the "composition mode" after the hatch 120 is closed, the data set (DS) flag and the data change (DC) flag are set in advance so that the required stock start control can be executed according to the main flow shown in FIG.
Set the flag and card reading (CR) flag to "1", respectively, and set the flag for double braiding.
Set the FWD, KRC flag, and vertical double flag to the initial values of "1", "0", and "0", and set the data change pause (DHP) flag to "1" with pause. "First stage (1))
Recall the contents of the memo and select “DN・” for the number of rows (middle row).
REG", the content of the SN register is set to the "0" step state, and the first stage data, which is the content of "DN REG", is transferred to the SPU 1 and displayed on the numeric display section 111.

In addition, when the MPU receives “C” data representing the correction key, the MPU clears the contents of “D′・REG” to “000” according to the flow in Figure 82.
It is transferred to the SPU 1, displays "0" on the number display unit 111, stores "0" without a number in the number flag, and turns off the left and right lamps L15 and 16 if necessary.

In addition, the MPU follows the flow in Figure 81, and the SPU
When key-in data "D" is transferred from 2, if the step status is not "0" from the contents of the SN register, this is assumed to represent the left key.
Follow the flow in Figure 82 and set “D′・REG” to “000”
, write “1” as the left data to D3, and then write “000” as the content of “D′・REG” to SPU.
1 and set the display on the numeric display section 111 to "0".
At the same time, the left display lamp L15 is turned on based on the content "1" of D3. 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 numeric value, the numeric flag is set to "0" without it. , write “0” step status to SN register, and write “D′・
The numeral data that is the contents of "REG" is stored in the stage number (middle stage) "DN REG", and the numeral data that is the contents of "D'REG" is transferred to the SPU1, and the numeral data that is the content of continues to be displayed, and lights up the step lamp L0. If there is no digit,
Assuming that the card 59 is in the set state where the set line is aligned with the upper edge of the insertion section 140 and the card is removed, the "DN"
Write ``000'' to ``REG'', store step ``0'' to SN register, and turn on step lamp L0.

In addition, the MPU follows the flow in Figure 81, and the SPU
If key-in data "E" is transferred from 2, if the step status is not "0" from the contents of the SN register, it is assumed that this represents the right key.
Follow the flow in Figure 82 and set “D′・REG” to “000”
, write the right data “2” to D3, and then write “000”, the contents of “D′・REG”, to SPU
1 and set the display on the numeric display section 111 to "0".
At the same time, the right display lamp L16 is turned on based on the content "2" of D3. However, if the contents of the SN register are step status "0", it is assumed that "E" is the data representing the rework key, and the rework control shown in Fig. 83 is executed, but the details will be described later. be done.

By the way, the scan operation executed by the MPU according to the flows shown in FIGS. 81 to 83,
To explain the key input control in which the SPU1 and SPU2 cooperate with each other with reference to FIG. 18, as the hatch 120 is first opened, the lamp L0 lights up, and the number display section 111 shows the number for the number of stages (middle stage). The contents of "DN・REG" are displayed. This “0”
Input data entered using the numeric key 110 in the step state and displayed on the number display section 111 in response to this input data is used as rework data or a step to advance or return the card 59 to an arbitrary step. It is effectively used as alignment data, and in response to subsequent operations of the reshaping key 118 and the reversing key 116, various control operations are executed based on the respective keys. In the "0" step state with a numeric value, even if the step key 113 is operated, there is no display change and the electronic buzzer BS does not sound, so it is determined that the key operation is invalid. In order to enable the step key 113 in this state, it is sufficient to operate the correction key 112, which clears the digit display and returns to the "0" step state with no digit.

In the "0" step state with no number set, for example, the card 59 is set when the set line 67 is in the insertion section 14.
0, and then the row start key 117 is operated, the row of pixel areas 61 (start row) on the card selected based on the content of the "Start row (1)" memo is ) is the reading position J of the sensor 92
The above-mentioned feed start control is executed, such as advancing the card 59 in stages so as to match the . In addition, in the "0" step state with no number set, the step return key 116
When is operated, contrary to the start key, the set line 67 of the card 59 is returned to the initial set position corresponding to the upper edge of the insertion portion 140, and so-called card removal is executed.

When the stage return key 116 is operated in the "0" step state with a set number, the stage number is changed to the stored data of "DN REG" (same as the contents of "G REG" for the stage number (middle stage) of SPU2). By comparison, the row of pixel areas 61 in the row that matches the content of the number data is at the reading position J.
The card 59 is sent back and alignment control is executed to correspond to the above.

Even if the start key 117 and step advance key 116 are operated more than once in the "0" step state with no numerals, they function effectively only the first time and have no effect after the second time. An electronic buzzer will sound each time the key functions.
The BS beeps and alerts you.

Also, in the “0” step state without a numeric value,
When the step key 113 is operated, the state enters the "1" step state with no numeral, the lamp L1 lights up, the data input corresponding to the first stage of "Momo A" is called, and the numeral display section 111 shows ,external
The data stored in the "Start stage (1)" memo in RAM is recalled and displayed. 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 enters a "1" step state with a numeral. The left and right keys 114 and 115 have no function. If you make a mistake in operating the number keys 110, use the correction key 112 to change the number display area 1.
The display of 11 is cleared to "0" and returns to the "1" step state with no numerals. From the step state "1" to "C", the step back key 116, the start key 117, and the rework key 118 are disabled, and no operation occurs even if these keys are operated.

When the step key 113 is operated in the "1" step state with a numeric value, the numeral display section 1 at that time will be displayed.
The data displayed in 11 is written to the corresponding step memo "Start stage (1)" and the lamp L2 lights up, and the number display section 111 shows the "Last stage (2)" memo. The stored data will be displayed and the state will be "2" step with no digits.

In step state "2", if the step key 113 is operated after numeric data is input using the numeric keys 110 by the same operation as above, the input data is written to the "last stage (2)" memo. Then, the lamp L3 lights up, and the stored data of the "Model A(3)" memo is displayed on the numeral display section 111, and the "3" step state with no function is entered. In response to this, when the numeric key 110 is operated and the step key 113 is also operated, the input data is written in the "model left A (3)" memo, and then the lamp L4 is lit. , the stored data of the "Model A(4)" memo is displayed on the numeric display section 111, and the state is set to "4" step with no numeric value. Repeat the same procedure to press number key 110.
When the step key 113 is operated, the input data is written in the "Model A(4)" memo. In operating the step key 113 at this time,
The step status changes depending on which position the pattern selection switches SW1 and SW5 are set.
For example, in the case of "Zen moyo", the operation of the step key 113 is the last input to be set as "Zen moyo", and especially in the lighting step state of step lamps L5, 6, and 7. The data input is automatically advanced by SPU2, the OK lamp L13 lights up, and furthermore, the number display section 111
The display is cleared to ``0'' and the process advances to the ``D'' step state with no digits. At this time, the reversing key 116, the start key 117, and the reshape key 118 become effective again.

If the step key 113 is operated, the error lamp L14 lights up and the electronic buzzer goes off.
If the BS beeps, it is determined that the numeral data displayed on the numeral display section 111 at that time is excessive, and the error lamp L
When 14 is lit, only the correction key 112 becomes effective, and the other keys do not function at all. Therefore, there is no choice but to operate the correction key 112, and in response, the numeric keys 110 and step keys 113 are enabled, and the display on the numeral display section 111 is cleared to "0", indicating that there is no numeral. Returning to the step state, new numerical data can be input.

In addition, when the lamp L4 is lit and input data is displayed on the numeral display section 111 in the step state of "4" with a numeral, the pattern selection switches SW1 and SW5 are set to "1". and when the step key 113 is operated, the lamp L5 lights up, and furthermore, the lamp L17 lights up, and the operation of the left and right keys 114 and 115 is called, and the "Group A (5)" memo is The stored data is recalled, and either the left or right lamp L15 or L16 that matches the content of the left and right discrimination data is lit,
In addition, numerical data (needle number) is displayed on the numeral display section 111, and a "5" step state with no numeral is displayed. At this time, since the input data corresponding to the lamp L5 includes left and right discrimination data, the numeric keys 110 are temporarily disabled.

Therefore, when either the left or right key 114 or 115 is operated first 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 L is
15 is lit, and when the right key 115 is operated, the right lamp L16 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 number key 1.
10, and when the step key 113 is operated after that, the new left/right discrimination data and needle number data are written in the "Basic A (5)" memo, and the lamp L6 lights up in the same manner as above. ``SELECTION A (6)'' A call display similar to the above is made based on the contents of the memo, and the step state is ``6''. If you make a mistake in operating the left and right keys 114 and 115, or if you make a mistake in the needle number data, press the correction key 112 to press the left and right keys 114 and 11 again.
5 will be valid, so you can freely try again.

Lamp L6 lights up and the data to be input into the "Selection A (6)" memo is called "6"
In the step state, if either the left or right keys 114, 115 or the numeric keys 110 are operated based on the data of the desired needle selection range, and then the step key 113 is operated, the digit display section 111 at that time will be displayed. The data displayed (needle number) and the left/right discrimination data by lamp lighting are written in the "Selection Left A (6)" memo, then the lamp L7 lights up, and then "Selection Right A (7)" is written. The memo is displayed and the lamp L17 is also turned on to enter the "7" step state.

Thereafter, in the same manner as described above, when the step key 113 is operated after inputting the required data based on the call display in which the lamp L7 lights up, in response to this, the OK lamp L13 lights up together with memory writing,
Proceeding to the "D" step state, the end of data input to be entered as "1" is announced.

Further, when the lamp L7 is lit and the step key 113 for memory writing is operated, if the setting state is "2",
Next, in order to input data for "Momo B", the lamp L8 is turned on, and the contents of the "Moyo B (8)" memo are called up and displayed. Therefore, after the same operation as above is repeated and the required data is input, finally, when the step key 113 for memory writing is operated based on the call display in which the lamp L12 lights up, the response is returned. OK lamp L13
lights up, and the end of the data input to be entered is announced as "2 more".

Then, when the step key 113 is further operated in the step state of "D" with no numeral, in which the OK lamp L13 is lit and "0" is displayed on the numeral display section 111, the OK lamp L13 is turned off. At the same time, the lamp L0 is lit again, and the state returns to the "0" step state similar to the initial stage of hatch opening. Sometimes, when the corresponding lamps L1 and L2 light up in each step state and the memory data is recalled and displayed, the numeric operation for inputting new data is not performed, and the step state without a numeric value is entered. If the step key 113 is operated while the state is still the same, the process immediately advances to the next step state. Therefore, by continuously operating the step key 113, you can select "DN REG" for the number of steps (middle step) and the contents of each step memo from "Start step (1)" to "Selection B".
You can call up the required data of "(C)" 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 to change the partial data. You can also do it.

Sometimes, in the initial "0" step state or the "D" step state where the end of data input is announced, the pattern selection switches SW1 and SW5 change from the set position of "2" or "1" to " You can freely switch to "All data", and when entering new numeric data in any of steps "5" to "C" or calling and displaying, you can also switch to " It is also possible to switch freely to the "all patterns", and when the hatch 120 is closed, the data of the standard position and needle selection range that are compatible with all patterns are automatically calculated and written in the step memo. . In addition, the data input order corresponding to "Moto-Left" and "Moto-Right" and "Selection-Left" and "Selection-Right" can be started from any order within those groups, and the system will automatically check and input the data as needed. If any, correct data is corrected and accurate data is written in each step memo.

However, you are free to input the starting position (first stage) and end position (final stage) in the stage direction of "Momo A", but for example, if the step lamp L1 lights up and you input it first, If the first row data is larger than the input last row data after the step lamp L2 lights up, the knitting pattern in the upper and lower direction will be realized on the knitted fabric, and the knitting pattern will be knitted in the reverse order. By inputting this information, if the first row data is smaller than the last row data, the knitting pattern will be realized on the knitted fabric in the same vertical direction as the knitting pattern. Therefore, the key-in is performed in an input order that matches the vertical direction of the desired knitting pattern.

By the way, when the MPU operates according to the external interrupt flow shown in FIG. 86, when the carriage passes near the approximate center of the needle bed, it changes the content of the center flag to "1" after passing the center, and If the carriage reverses its running direction after that, on the condition that the content of the center flag is "1", it will be changed to "0" before passing, and the DC flag will be changed to "1" with data change. It has a relationship of setting.

Therefore, when the hatch 120 is closed and in the "organizing mode", the MPU returns to the main flow shown in FIG. If "1" is found, "data change" control is immediately executed. i.e. external
Transfer the 200-bit contents of the "Data Set Memo" in RAM to the "Data Change Memo" as is, matching each bit address. For example, transfer the contents of bit address "200" of the "Data Set Memo" to the "Data Change Memo". Transfer the bit address to "200", and also write the contents of "201" to "201" and "202".
are transferred to "202" and so on in order, and finally the contents of bit address "399" of "Data Set Memo" are transferred to bit address "399" of "Data Change Memo". Next, change the DC flag to “0” without data change, and then
Even if the flag has "1" for L carriage or "0" for K carriage, the switch will not work.
SW6 and SW7 do not have double amikomi (KRC),
When it is set to "no vertical multiplier", the card read (CR) flag is immediately set to "1", and the data set (DS) flag is set to "1" (dot).

After that, when the MPU inquires about the CR flag according to the flowchart in Figure 80, it returns "1" indicating that the card has been read.
If there is, "card reading" control is executed immediately. That is, by first transferring data "2" to the SPU 2, the "card reading" and "card sending back" controls are executed. Then, the ``card'' of 4 bits per word is transferred from SPU2.
data” signal to the external RAM’s “correct right” and “correct left” signals.
Write to each bit address of the card data memo in the required order.

That is, when the sensor 92 initially moves forward in the right direction according to the flowchart in FIG.
4 corresponding to the pixel area 61 from "1" to "4"
By transferring the bit "card data" signal, the pixel area 61 of "1" is transferred to the bit address "0" of the "right right" memory which has been addressed in advance.
Similarly, the signal of the pixel area of ``2'' is written to the bit address ``1'', the signal of the pixel area of ``3'' is written to the bit address ``2'', and the signal of the pixel area of ``3'' is written to the bit address ``3''. After writing the signal of the pixel area of "4" to , it waits for the next data transfer from SPU2. And "5" to "8"
Once the "card data" signal corresponding to the pixel area 61 of
``5'' in memory bit addresses ``4'' to ``7''
Write the signals in the pixel area of ``8'' in order, and in the same way, every time the ``card data'' signal is transferred from the SPU2, write to the required bit address of the ``right right'' memory, and finally, `` Pixel area 61 of “60” at bit address “59” of “right right” memory
At the stage where the "guard data" signal corresponding to the "guard data" signal has been written, the "correct left" memory is set to be addressable instead of the "correct right memory". After that, when the sensor 92 reverses its travel and travels back to the left, the SPU 2 reads the 4-bit "" corresponding to the pixel regions 61 from "60" to "57" based on the reading device of the pixel region 61 in one row horizontally. By transferring the "card data" signal, the bit address "0" of the "correct left" memory that was previously addressed
Write the “card data” signal corresponding to the pixel area 61 of “60” to the pixel area 61, and write the signal of the pixel area of “59” to bit address “1” and the signal of the pixel area of “58” to bit address “2”. After writing the signal of the pixel area "57" to bit address "3", the next data transfer from SPU2 is awaited. Then, once the "card data" signal corresponding to the pixel area 61 of "56" to "53" is transferred, the "card data" signal is transferred to the bit addresses "4" to "7" of the "positive left" memory in the same manner as above. 56" to "53" pixel area in order, and write the signals in the pixel area "56" to "53" in the same order, and then write the signals to the SPU.
Every time the "card data" signal is transferred from 2, it is written to the required bit address of the "right left" memory, and finally, the pixel area 61 of "1" is written to the bit address "0" of the "right right" memory. Write the corresponding “card data” signal.

As described above, the MPU regularly stores bits in the same order of bit arrangement in the "right-right" memory, corresponding to the horizontal rows of the pixel area 61 on the card 59, based on the reciprocating reading scan of the sensor 92. In addition, the "normal left" memory stores bits in reversed left/right bit order. After this, the MPU resets the card read (CR) flag to "0", and then performs the "DN" for the number of stages (middle stage), which is similar to the "card send back" control executed by the SPU2 according to the flowchart in Figure 66.・Execute step control of “REG”,
In particular, by referring to the FR flag and correcting the card feed direction flag if necessary, always match the contents of SPU2's "G REG" to "DN REG".
Rewrite the contents of.

Sometimes, following the flow in Figure 80, the MPU
After resetting the DS flag to ``0'', the KL flag was set to ``0'' for K carriage, and for example, switch SW6 was set without double input (KRC), and switch SW7 was set with vertical double. In this case, check the vertical multiplication flag that stores "0" indicating no card feeding as the first vertical multiplication at the beginning of the game, and if it is "1" indicating card feeding, change it to "0" indicating no card feeding. After that, the same feed control operation as above is executed to send back the card 59, but if it is ``0'' indicating no feeding, change it to ``1'' indicating feeding, and set the DS flag to ``data set''. The CR flag is not set to ``1'' indicating that the card is being read, and the card 59 is not read or sent back. That is,
Even if the MPU performs "data change" control based on the carriage reversal signal, card reading and feeding back are stopped every two times, and intermittent feeding for vertical doubling is performed.

Also, according to the flowchart in Fig. 80, if switch SW6 is set to double read (KRC), the MPU checks the contents of the FWD flag, and if it is "0" indicating feed is enabled, the MPU checks the contents of the FWD flag. , change this to "1" with sending, and then complement the contents of the KRC flag to "0" if it is "1" and "1" if it is "0", and then change the CR flag to "1" with the DS flag. The card 59 is set to "1" and the card reading and sending back control operations similar to those described above are executed to send the card 59 back. However, if it is "1" indicating no feeding, it is set to "0" indicating feeding. Change, DS
Only the flag is set to "1".

At times, in the flowchart of FIG. 80, the content of "DN REG" for the number of stages (middle stage) is the pixel area 6 on the card 59 that the sensor 92 corresponds to at that time.
The number of stages corresponds to 1, and the MPU sets the data change flag to 1 when the carriage reverses its running direction. Therefore, for example, as shown in FIG.
is set to "Repeat" and data of "1" and "30" are stored in the "Start stage (1)" memo and "Last stage (2)" memo, follow the flow in Figure 80. The operating MPU is determined by the number of pixel area stages on the card 59 corresponding to the sensor 92 (contents of "DN REG")
, "1" depending on the number of times the carriage reverses its travel.
So that it changes to tier, "2" tier, "3" tier...
SPU2 controls the card 59 to advance in stages,
After the "30" stage, the card 59 is returned to the "1" stage again, and then the "2" stage and the "3" stage are repeated. However, if the card is set to ``vertical facing'', after proceeding to the ``1'' stage, ``2'' stage, ``3'' stage, etc. in the same way as above, the next card after the ``30th'' stage is 5
Move 9 back by one step to make it "29" step, then,
It advances to "28" stage, "27" stage, etc., and after returning to "1" stage again, it is controlled to repeat "2" stage, "3" stage, etc.

In addition, when switch SW6 is set to "double input", each of the above-mentioned stages changes by one stage each time the carriage reverses its travel twice.
In relation to each one run of the carriage, there is an intermittent feed such as, for example, "3" stage, "3" stage, "4" stage, and "4" stage.

After that, the MPU follows the flow in Figure 80 to
If "1" indicating that data set is present is stored in the flag, the process moves to the "data set" flow shown in FIG. 84 and the required "data set" control is executed.

That is, the MPU uses the "data set" in Figure 84.
According to the flow, first set the 2 flag to 0, which is 1, and then set the register to address the ``right right'' and ``left'' memories of the card data memo, which is the first storage device. After storing the "C" data that specifies the "normal right" memory, the process moves to the "PN set" flow shown in Figure 85, and the memory bit write data to be executed subsequently is stored in the forward/reverse direction. Determine the contents of the PN flag, which is the basis for determining whether to set it to "1" (without) or "0" (with forward/reverse control). That is, according to the flowchart in FIG. 85, if the switch SW6 is not double-loaded, if the switch SW6 is set to forward/reverse (KRC), the PN flag is set to negative (KRC). Otherwise, it stores a positive “0” and completes the PN set.

Next, according to the flowchart in Fig. 84, if there is a positive "0" based on the contents of the PN flag, all bit addresses of the "data set memo" are set to "0" with no needle selection. If there is a negative (reverse) ``1'', ``1'' with needle selection is also set across all bit addresses of the ``data set memo''. Then, based on the switching positions of pattern selection switches SW1 and SW5 determined from the contents of the SW register, if, for example, all moyo or 1 moyo is selected, the "model left A (3)" memo is selected. Recall the content ``d'' of , 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.
Similarly, write the data obtained by converting in the same way from the contents of the memo "Mosho A (4)" to the "Mosho" cash register, and furthermore,
Recall the contents of the ``Basic A (5)'' memo, and this is the ``Left a
When the data is "No.", change it to the data "300-a", and when it is the data "No. C on the right",
Change the data to "299+C" and convert it to the data corresponding to the bit address of "Data Set Memo", then write it to the "Basic" register, and also write it to the "Selection A" register.
(6)" and "Selection A (7)" are called up, and after the same conversion correction as above, write them in the "Selection Left" and "Selection Right" registers.

Next, the left and right effective widths (pattern widths) of the knitting pattern selected as Momo A are determined from the register contents of "Momo Left" and "Momo Right", and this is calculated, for example.
“T.REG” as a temporary “Moyo W” cash register
The ``reference position'' is checked based on the content of the pattern width. That is, as shown in FIG. 91, if the reference position data that is the content of the "base" register is equal to the content of the "select left" register, it is left as is, but for example, if it is larger than the "select left" register, it is , by sequentially subtracting the contents of the "base" register according to the pitch of the pattern width,
Find the reference position on the left that matches or is closest to the contents of the "Select left" register, and if it is smaller than the contents of the "Select left" register, match it to the pitch of the pattern width and move it to the "Basic" register. By sequentially adding the contents, the left reference position that matches or is closest to the "select left" register is determined. Then, if the horizontal multiplication switch SWO is set to horizontal multiplication based on 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 84, if the KL flag contains "0" for K carriage, the content of the 2-carriage flag is asked, and if it is 1-carriage or all-carriage, it is set to 0 in advance. Check the switching position of the left and right hand A switch SW3 from the contents of the SW register, and for example, if there is no hand, the register and the contents of the registers ``model left'' and ``model right'' will remain as they are. However, if you want to
Complement the second bit of the cash register and make “C”
By changing from to "E", the "correct left" memory is specified as the address, and the data of "59-e" is calculated from the contents "e" of the "mock right" register, and the "mock left" memory is specified. Register contents “h” to “59−
Calculate the data of ``h'', write the ``59-e'' data to the ``Moto-left'' register, and write the ``59-h'' data to the ``Moto-right'' register, and specify the ``Correct Left'' by both registers. The bit address number of the memory is made to correspond to the information effective width data that is the memo content of the above-mentioned "Model A(3)" and "Model Right A(4)".

Next, according to the flowchart in Figure 84, the MPU resets the base flag used in the previous reference correction to "0", resets the cross (horizontal multiplication) flag to "0", and then resets the "base flag" to "0". ” Recall the contents of the register and write it to the “data count” register, and write the contents of the “mock left” register to the “mock count” register. Then, starting from the reference position, which is the contents of the "base" register, and continuing until the position where the contents of the "data count" register match the contents of the "selection" register, the "mock count" and "data count" are executed for each bit address. ” Determine the final value when adding 1 to the contents of the register, and store the result in the “mock count” and “data count” registers. Also, if there is horizontal multiplication,
The flag was changed to "0", "1", "0", "1", etc. for each bit address mentioned above, and the "mock count" register was added by 1 for each "1". Determine the final value of the time, and use the flag, "mock count", and "data count" to display the result.
It will be set on the cash register.

Next, after the contents of the "Select Left" register match the contents of the "Data Count" register, for example, if the PN flag is "0", the "Right Right" specified by the register at that time is selected. , the ``0'' and ``1'' contents of the bit address specified in the ``imitation count'' register in either the ``correct left'' memory and the ``imitation count'' register are called, and only when the bit contents are ``1'', the ``data'' is read. Write ``1'' to the bit address of the ``Data Set Memo'' specified by the ``Count'' register. If,
If the PN flag is "1", it is either the "correct right" or "correct left" memory specified by the register at that time, and the bit address specified by the "simulated count" register. The contents of "0" and "1" are called up, and only when the bit contents are "0", "0" is written to the bit address of the "data set memory" specified by the "data count" register. Then, on the condition that the contents of the "Data count" register do not match the contents of the "Selection" register,
Add “1” to the contents of the “Data Count” register,
Furthermore, is there “1” for L carriage in the KL flag?
If there is a "0" in the K-carriage but there is no horizontal multiplier, the "mock count" will be counted, provided that the contents of the "mock count" register do not match the contents of the "mock right" register.
After adding "1" to the contents of the register, the program returns to the memory bit writing flow and repeats the same operation.

If the contents of the "mock count" register match the contents of the "mock right" register, the contents of the "mock left" register are reset to the "mock count" register, and then the same bit write operation as above is performed. But sometimes,
If the contents of the ``data count'' register match the contents of the ``selection right'' register, it is assumed that the write operation up to the bit address that matches the contents of the ``selection right'' register has been completed, and the ``data count'' register of "Set"
After completing the control, reset the DS flag to "0" indicating no data set.

Sometimes, in the above memory bit write operation, if the KL flag has "1" for the K carry and there is a horizontal multiplier, the content of the above "data count" register is incremented by 1 by effectively using the flag. After that, by asking the content of the read flag, if it is "0", it will be rewritten to "1" and the process will immediately return to the above memory bit writing flow, but if it is "1", then Shift to the flow of adding 1 to the "mock count" register instead of "0". Therefore, the contents of the required bit addresses of the "right right" and "right left" memories specified by the "simulation count" register are two consecutive bits of the "data set memo" specified by the "data count" register. For example, if the contents of bit address ``20'' of the required memory in the ``Right Right'' and ``Left Right'' memories are ``1'', the ``Data Set Memo'' will be written to the corresponding address. bit addresses ``300'' and ``301'' respectively.

Also, according to the flowchart in Fig. 84, if the pattern selection switches SW1 and SW5 are set to 2 based on the contents of the SW register, the MPU first performs the bit writing operation of "Momo B". , "Ki B (A)", "Sen right B (C)", "Sen right B (B)", "Mo right B (9)
”,
Recall each content of the "Mosa B (8)" memo and use the same conversion correction as above to input the data into the "Basic", "Sen Right", "Sen Zu", "Mo Right", and "Mo Left" cash registers. After changing the write/2 flag to "1", the process moves to the standard correction flow and the same control as described above is repeated. In particular, in the bit write operation of "Momo B",
The MPU switches the check operation of the left and right contacts.
This is done based on the switching position of SW2.

Then, according to the flowchart in Figure 84, the MPU that has finished the bit write operation for "Momo B"
changes the contents of the 2nd flag to ``0'' based on the content ``1'' of the 2nd flag stored earlier, and then performs the bit write operation of ``Bound A''.
(5)'', ``Senso A(7)'', ``Sensa A(6)'', ``Mosho A(4)''
, Recall the contents of the "Mosho A (3)" memory and use the data obtained by the same conversion correction as above as "Basic", "SenRight", "Senso", "MosRight", "Senso" Write on the register. Then, the same control as described above is repeated to complete the "data set" control.

By the way, in the "PN set" flow shown in Figure 85, if there is double input,
The contents of the KRC and FWD flags are effectively used, and the contents of the PN flag are determined in relation to the settings of the forward/reverse switch SW8. Then, at the beginning of the pile, "1" indicating no feed is stored in the FWD flag and "0" is stored in the KRC flag, so that the double pile formation is performed according to the "PN set" flow shown in Fig. 85. When started, the MPU executes the "data set" control in the flow shown in Figure 84, and the first time the PN flag is set to a negative (reverse) "1", and the second time it is set to a negative (reverse) "1". A positive “0” is set,
Similarly, 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. "Correct", "Correct", "Reverse"
It is regularly repeated with a period of . Moreover, according to the main flow shown in FIG. 80, the card 59 is fed one step at a time for every two times the carriage reverses its travel, based on the contents of the FWD flag. The signal of the same stage is used twice: "forward" and "reverse". As a result, it is possible to deal with the double amikomi formation as shown in FIG.
9, the necessary needle selection operation can be carried out appropriately. At this time, if the vertical multiplication switch SW7 is set to vertical multiplication, the feeding operation of the card 59 becomes intermittent, and vertical multiplication can be performed freely even with double threading. If the switch SW8 is set to forward/reverse, the PN flag is set in the opposite manner to the above, first "normal", then "reverse", then "reverse", "normal", "normal". , it becomes "reverse", and it is possible to perform forward and reverse handwriting even with double amikomi.

According to the “data set” flow in Figure 84,
Various switches that are one of the needle selection mode setting devices
Based on the ON/OFF contents of SW1, 5, 2, and 3, select the required one of the first storage device, ``Right Right'' and ``Right Left'' memory, and then select The operation of writing the bit contents of "0" and "1" to a predetermined bit address of the "data set memo" which is the second storage device (the same bit address also corresponds to the "data change memo") is shown in FIG. This can be easily understood from the embodiment diagrams of the knitting patterns illustrated in FIGS. 55 to 55. In particular, in the flowchart shown in Fig. 84, by effectively utilizing the "correct right" and "correct left" memories and specifying it by the address data that is the contents of the register, the bit arrangement order according to the required needle selection mode can be set. Select the memory of, and furthermore,
Switch SW0, which is one of the needle selection mode setting devices
By writing the same bit contents "0" and "1" for each two consecutive bit addresses of "Data Set Memo" based on the ON/OFF contents of be done. Therefore, after the "data set" control in the flow shown in FIG. The needle selection data necessary to realize the knitting pattern set by all the needle selection mode setting devices is stored in each bit of the "data set memo" that corresponds to the knitting needles in a one-to-one relationship. In the address part, set the data "with needle selection (knitting needles selected at position B in Figure 3)" as bit content "1", and the data "without needle selection (knitting needles selected at position A in Figure 3)". The bit content is stored as "0".

According to the main flow in FIG. 80, after the MPU finishes the "data set" control, it checks the data change (DC) flag, etc., as described above, and executes the required control operations if necessary. If, for example, an external interrupt command of "L" is applied to the terminal during this operation, the flow immediately shifts to the interrupt flow shown in FIG. 86, and returns to the original flow after the required interrupt control is completed.

In other words, when an external interrupt command of "L" is given to the MPU terminal, when the "VIDEO1" signal rises from "L" to "H", SPU1 outputs "H" to port O3. In particular, the interrupt command from SPU 1 occurs when the carriages 13 and 20 are traveling to the left as described above, and when the carriage center lines C and D are
is given at a time point corresponding to the center position between each knitting needle 3.

Therefore, the MPU that performs external interrupt control according to the flowchart in FIG. 86 first checks the input of port R8 after saving the registers such as Acc, X, Y, etc. If there is, this will be used as a valid interrupt and the required interrupt control will be executed, but SPU1
When it is determined that the interrupt is not from the port R11, the "VIDEO2" signal given to port R11 is checked, and if it is "L", the interrupt command at that time is invalidated and the register is immediately sent. After recovery, the process returns to the main flow, and only when the level is "H", the interrupt command at that time is made valid and the required control operation is executed. At this point, as is clear from the timing relationships shown in FIGS. 23 to 26, the carriages 13 and 20 are traveling to the right, and the carriage center lines C and D are aligned with each knitting needle 3. This is the point in time corresponding to the center position between
This also matches the position where an interrupt instruction is given from SPU1.

If the MPU determines that the interrupt control is valid when the carriage is traveling to the right according to the flowchart in Figure 86, first, the "left reference" signal becomes "H".
If so, then the eighth
According to the "KLCH" flow in Figure 7a, check the "KL determination" signal, which is the input signal of port K0, and if it is "H", change "1" representing L carriage to "L".
If so, write "0" representing K carriage into the KL flag, and then perform left reference count correction. That is, when one of the KL carriages is traveling rightward from the left end of the needle bed and one of the magnets 42, 43, 44 mounted on the carriage approaches the left reference element 40 (see Fig. 30b). Based on the valid external interrupt, the MPU stores ``199'' in the ``C REG'' for carriage count, and checks the ``phase'' signal, and if ``L=0'', the SL number Write "7" in the "Nd" register for counting, and if "H=1", write "F" in the "Nd" register.

As understood from Fig. 12, K carriage 1
When the left magnet 42 of 3 or the magnet 44 of the L carriage 20 approaches the left reference element 40, the electromagnet
The bit address number corresponding to the knitting needle for which energization of the SL should be started is "199", and
In the state in which the belt and carriage are connected when a "phase" signal of "1" is output, there is an electromagnet SLF corresponding to the cam wheel position suitable for the start of energization, and a "phase" signal of "0" is also generated. When is output, there is an electromagnet SL7. Therefore, by executing the left reference count correction as described above, subsequent needle selection timing can be secured. However, K
The magnet body 43 on the right side of the carriage 13 is the left reference element 4
Even when the count is close to 0, the same count correction as described above is performed, but as the carriage 13 continues to move to the right, the left magnet 42 moves closer to the left reference element 40.
The needle selection timing shown in FIG. 9 is secured by the count correction at that time.

If the MPU determines that the interrupt control is from SPU 1 when the carriage is traveling to the left according to the flowchart in FIG. 86, it first asks whether the "right reference" signal is "H", If so, then follow the “KLCH” flow in Figure 87a and select “KLCH”.
Check the "Discrimination" signal, and if it is "H", write "1" representing L carriage, and if it is "L", write "0" representing K carriage into the KL flag, and then correct the count of the right reference. Do this. That is, while one of the KL carriages is traveling from the right end of the needle bed to the left, the magnets 42, 43, 4 mounted on the carriage
4 is close to the right reference element 38 (see Figure 30a), the MPU
is "400" in "C・REG" for carriage count.
At the same time, ask the "phase" signal at that time, and if "L = 0", write "0" in the "Nd" register for SL number counting, and also write "H = 1".
If so, write "8" in the "Nd" register.

As understood from Fig. 11, K carriage 1
When the right magnet 43 of 3 or the magnet 44 of the L carriage 20 approaches the right reference element 38, the electromagnet is moved while satisfying the timing shown in FIG.
The bit address number corresponding to the knitting needle to which SL should start energizing is "400" and "1".
In the state in which the belt and carriage are connected when the "phase" signal of "0" is output, there is an electromagnet SL8 corresponding to the cam wheel position suitable for the start of energization, and a "phase" signal of "0" is also output. When there is an electromagnet SL0. Therefore, by executing the count correction of the right reference as described above, subsequent needle selection timing can be secured. However, the left side magnet 42 of the K carriage 13 is the right reference element 38.
When approaching the right reference element 38, the same count correction as described above is performed, but as the carriage 13 continues to move leftward, the right magnet 43 approaches the right reference element 38, and the count correction at that time causes the carriage 13 to move leftward. , the needle selection timing shown in FIG. 9 is secured.

Also, according to the flowchart in Fig. 86, when the carriage starts traveling from the end of the needle bed, if either the "left reference" or "right reference" signal is "H", the carriage Direction F sign flag (hereinafter referred to as F
If the carriage is running to the right, "1" is stored in the flag (referred to as a flag), and if the carriage is moving to the left, "0" is stored.
is stored and used for subsequent detection of carriage travel reversal.

According to the flowchart in Fig. 86, the MPU that executes the valid interrupt operation normally determines whether the valid interrupt operation is valid when the carriage travels to the right, based on the fact that the "left reference" and "right reference" signals are "L". If it is an interrupt, “C.
Add 1 to the contents of “REG” and add 1 to the contents of “Nd” register.
to add. Then, by setting port O4 to "L" output, an external interrupt command is given to SPU2, and after the data bus lines of ports R12 to R15 are released, the contents of "C REG" after the above addition are used. The contents of the bit address of "Data Change Memo", which is the first storage device specified by Recall contents. Then, when the bit content is “0”, the “A” data representing “no needle selection” is sent to SPU.
1, and then transfers to the SPU 1 the number data "X" of the electromagnet SL, which is the content of the "Nd" register after the above addition and is to be energized at that time. If the retrieved bit content is “1”, the “B” data representing “needle selection” is sent to SPU1.
, and then the contents of the "Nd" register. Also, when the carriage moves to the left,
If it is an external interrupt from SPU1, the MPU will
REG" and "Nd" registers, and based on the subtracted contents, call from "Data Change Memo" similar to the above, and SPU1
Transfer to. In addition, the addition and subtraction of the "Nd" register is
Expressed in hexadecimal, for example, adding "1" to "F" yields "0", and subtracting "1" from "0" yields "F".

After completing the needle selection data transfer to SPU1, the contents of Y addresses 0 to 4 of the flag register in the internal RAM are transferred to the flag memo in the external RAM, and then, from the contents of the transfer flag, immediately before the interrupt,
Only when the data is being transferred to SPU2, the data to be transferred is output again to ports R12 to R15, and normally, after canceling the interrupt of SPU2,
The register is recovered and the interrupt control in the flowchart of FIG. 86 is completed.

In addition, according to the flowchart in FIG. 86, when the MPU checks the open/closed state of the hatch 120 using the hatch flag after adding and subtracting the "Nd" register, if there is a "1" for the hatch "open", the MPU reads the information from the memory. Registration is immediately recovered and interrupt control is completed without performing a bit recall operation.

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 of these bit addresses has "0" and "1". ” needle selection data is stored. Therefore, after first performing the above-mentioned left or right reference count correction, in relation to the travel of the carriage for one pitch of knitting needles, specifically, the carriage center lines C and D are at the center position between each knitting needle 3. Each time an interrupt arrives, effective interrupt control is executed using an interrupt command from SPU1, so based on this, the MPU
According to the flowchart shown in Figure 6, the electromagnet SL to be energized is selected from time to time, the needle selection data is called, etc., with the required relationships shown in Figures 10 to 12, and more specific information is selected. Specifically, the selection cam mechanism 16, 16a mounted on the carriage and the handle plate 45
The needle selection timing is ensured through cooperation with a to h, and knitting needle selection control is executed in a certain order.

In some cases, the MPU adds 1 to or subtracts 1 from the content of "C.REG" according to the flow in Figure 86, and then changes the content to "300" according to the flow of "CPCH" in Figure 87b. Only if it is, reset the data change pause flag (DHP flag) for reshaping to "0" and reset the carriage removal flag (consisting of 2 bits) to "00" indicating no removal. Then, the subsequent "data change" control can be performed without any trouble, and "1" representing after passing the center is stored in the center flag for carriage center passing, and is used for subsequent reversal of carriage travel.

That is, when the carriage reverses its traveling direction, for example from left to right or from right to left, the effective interrupt is determined based on the interrupt command output immediately after that, according to the flowchart in FIG. The MPU that performs the load control adds and subtracts the contents of the "C・REG" and "Nd" registers by 1, respectively, and then, since the F flag has the contents opposite to the carriage direction at that time,
First, the M sign flag (M flag) is set to "1". 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, a case where the carriage continues traveling without turning around again and reversing. Then, only when the carriage has progressed in the reverse direction by one knitting needle, is the carriage reversal determined to be normal.

Therefore, with the M flag set to ``1'', the MPU that performs the next effective interrupt control writes the contents of ``0'' and ``1'' to the F flag, which correspond to the direction in which the carriage is reversed. By executing carriage reversal control, the M flag is first reset to "0" in preparation for the next travel reversal, and the center flag is checked to see if it is "1" after passing through the center. For example, return it to "0" before passing,
Since the DHP flag is "1" only at the beginning of the rework and is normally "0" without removal, and the carriage removal flag is normally "00" without removal, the DC flag is After setting it to "1", the flow shifts to the "carriage reversal correction" flow shown in FIG. 87c, and count correction is performed.

That is, according to the flow shown in FIG. 87c, the MPU:
When the carriage reverses running from left to right, the content of the F sign flag is "1", so check the content of the KL flag to correct the count of the carriage reversal to the right. If there is "0", the content of "C・REG" after the above 1 addition is subtracted by "26", and the content of "Nd" register is subtracted by "A", but in the same way, "1" of L carriage is added to the KL flag. If there is, the count is corrected by subtracting "2" from the contents of "C.REG" and subtracting "A" from the contents of "Nd" register.

As can be understood from FIG. 10, for example, when the K carriage 13 is traveling to the left, the bit address number corresponding to the knitting needle 3 whose electromagnet SL is to be energized, that is, " If the content of "C・REG" is "305" and the content of "Nd" register is "9", then if the carriage reverses its direction of travel and travels to the right, this will result in: The bit address number corresponding to knitting needle 3, which should start energizing the electromagnet SL, is "280".
And the number of electromagnet SL becomes "0".
In addition, if it is an L carriage 20, it will be "304" and "0". Therefore, by performing the count correction of the carriage reversal to the right as described above, the subsequent needle selection timing is ensured.

Also, according to the flowchart in Figure 87c, when the carriage reverses from right to left, the content of the F sign flag is "0", so the MPU performs count correction for the left side of carriage reversal. Waka KL
If the flag has "0" of K carryage, "26" is added to the contents of "C REG" after the above 1 subtraction, and "A" is added to the contents of "Nd" register, but the same is added to the KL flag. If there is "1" in L carriage, add "2" to the contents of "C REG" and add "A" to the contents of "Nd" register,
Perform count correction. Therefore, when the carriage reverses its travel from right to left, a count correction that is opposite to the reversal of travel from left to right is performed to ensure subsequent needle selection timing.

According to the flowchart in Figure 86, when the carriage is reversed, the MPU sets the DC flag to "1" indicating that there is a data change, and after executing the valid interrupt control at that time, returns to the main flow in Figure 80. When proceeding with control, based on the above DC flag,
``Data change'' control is performed, and then, if necessary, the CR flag is set to ``1'' indicating card reading, and the SPU 2 is made to execute ``card reading'' and ``card sending back'' control. However, if the center flag is checked and there is a "0" before passing through the center, the DC flag can be left as "0", and based on the carriage reversal at that time, "data change" and ""Cardreading" and "Card sending 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".

Even if the "left reference" signal is "H", the MPU that operates according to the flowchart in FIG. 86 does not perform left reference count correction if the carriage is traveling to the left. Even if the "right reference" signal 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 the reference correction and perform the normal 1 addition/subtraction operation of the "C・REG" and "Nd" registers. This ensures the needle selection timing for all the needles on the needle bed.

By the way, it operates according to the flow shown in Figure 86.
The MPU includes, for example, carriage magnets 42, 43,
44 was close to the reference elements 38, 40, and the reference correction position was also the carriage reversal position. In case the carriage reverses at the position, the contents of the F flag are rewritten to prevent the carriage reversal correction from being performed again immediately after that, and the contents of the center flag are inquired and the above-mentioned carriage reversal correction is performed. The inversion flag setting and DC flag setting operations similar to those for correction are executed. Regarding the timing of these reference correction changes and carriage reversal, see Part 23.
This can also be understood from FIGS. 26 to 26.

By the way, when knitting the well-known lace stitch 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 in a cam arrangement on the auxiliary rail attached to the right end of the needle bed 2, set the connecting pin 28a of the L carriage 20 in a position where it can be connected to the belt 24, and then set the connecting pin 28a of the K carriage 13 By running both carriages alternately with the K carriages set in a position where they cannot be connected (the magnets 42 and 43 are also retracted in conjunction with each other), it is possible to Next, the knitting needles 3 are sorted by the sorting cam mechanism 16a of the L carriage 20, and the stitches are transferred, etc., and the construction proceeds. At this time, the magnet body 4 mounted on the L carriage 20
4 is close to the reference element, the KL flag is set to L.
"1" representing the carriage is written, and various controls are performed based on the contents of the flag, so L
The needle selection timing, etc. that is suitable for the carriage 20 is ensured, and thereby there is no need to provide a special KL changeover switch or the like and to manually change it.

According to the main flow in FIG. 80, the MPU sets the DS, DC, and CR flags to "1" at the beginning of the game based on the "key scan" control in the "data input mode" while the hatch 120 is open. When the hatch 120 is closed and enters the "composition mode", "card reading", "card sending back", "data set", "data change", "card reading", "card sending back" and Execute each control in the order of "data set". With this, for example, when starting formation with the row of pixel areas 61 in the "1" stage of the card 59 as the starting stage, the signal of the pixel area in the "1" stage, which is the starting stage, is read and the card Data memo "correct right" and "correct left"
The needle selection data is written in the memory, and based on the memory contents, the needle selection data is set in the 200 bits of the "data set memo" according to the key input data that is the contents of the step memo, including the various switch SWs that are the needle selection mode setting device, and the step memo contents. The needle selection data, which is the contents of the "data set memo" after the setting, is transferred to the "data change memo" as is. and,
The signal of the pixel area of the "2" stage of the card 59 that has been stage-advanced in advance is read and written in the "correct right" and "correct left" memories, and then the card 59 is stage-advanced and the same process as described above is performed. The needle selection data is set in the "data set memo".

Therefore, for example, when starting knitting with the K carriage at either the right end or left end position of the needle bed, the first carriage run immediately creates a needle selection pattern based on the card signal of the "1" stage. The knitting needles 3 can be sorted into positions A and B in FIG. 3.

Moreover, during this first carriage run, the DHP flag is set to "1" in advance at the beginning of the ride.
As a result, the DC flag is not set to ``1'' indicating that there is a data change, and the DHP flag is reset to ``0'' when passing through the center, and the center flag is set to ``1''. This makes the subsequent carriage reversal valid. Then, when the required knitting yarn is set in the thread head of the K carriage and the carriage is reversed again, the contents of the "data set memo" corresponding to the "2" stage card signal are changed to "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 since the card 59 has been advanced in stages in advance, the signal of the "3" stage is read this time. After passing through the "right right" and "right left" memories, it is set in the "data set memory".

Now, with reference to the flowcharts of FIGS. 80, 83, and 86, the rework control of the MPU will be explained. In this example, during knitting, if the butt of the knitting needle 3 collides with the gum or the knitting yarn gets tangled, and the carriage stops moving,
Or, if you have to unravel the knitted fabric due to a knitting failure, etc., when knitting only K carriage,
Use the number keys 110 to enter the number of unraveled rows of the fabric, or in knitting lace knitting using the L-carriage, the number of rows the L-carriage must run to return to the next row minus 1, using the numeric keys 110, and then press the reshaping key. It has a configuration that can be easily reworked by operating 118. In particular, if the carriage stops moving and must be removed from the needle bed, it is desirable 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. Specifically, before passing the standard, the hatch 120 is opened and the carriage is moved in. In this state, the number of stages for reshaping is set in the same manner as above, and the reshaping key 118 is operated. I try to do that.

In particular, the MPU that performs the reshaping control according to the flowchart in FIG.
Even if there is number data of "0", for example, if the knitted fabric is not unraveled but the pattern of needle selection is disturbed and the user wants to select the same row of needles again, the number may be set to "0". Therefore, rework control is executed using this as valid position data.

According to the flowchart in Fig. 83, 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. Based on this, it is determined whether to add two or three stages to the number of stages necessary to return the card 59. Also, if the carriage is removed, , then F
From the contents of the flag, considering whether it was removed while the carriage was running in the left or right direction, and from the contents of the set number data "D'・REG", at the first carriage run in the early stage of rework, Determine whether needle selection should be performed immediately or whether the needle should be passed without needle selection in the first stage.

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 one side, it is necessary to first pass the carriage through to the other side and then select the needle by reversing the movement. In addition, in the race edition, card 59
Matching the needle selection data for stitch transfer determined above, for example, if the needle selection data at the initial stage of re-stitching is for rightward movement, but the L carriage is in the right position, the first Needle selection can be performed while the carriage is running, but if it is in the left position, it is necessary to pass it straight to the right, and then select the needle when the carriage is traveling to the left.

According to the interrupt control flow in Figure 86, the MPU:
When performing “left reference” and “right reference” corrections,
If the hatch 120 is opened based on the content of the hatch flag, "01", which means that the carriage entered from the right when the "right reference" is set, is used as basic data for subsequent reshaping control. When "left reference" is selected, the carriage removal flag is set to "10", which means that the carriage entered from the left. Therefore, the MPU that subsequently performs the reshaping control shown in Fig. 83 sets the carriage removal flag to "01",
From the contents of "10", it can be detected whether the carriage has been removed or not, and it can also be determined whether the carriage will start running in the left or right direction at the initial stage of re-steering.
Therefore, the MPU can determine whether or not needle selection should be performed in the initial carriage travel direction at the initial stage of reshaping, regardless of whether the carriage has been removed or not, in accordance with the flow shown in FIG. 83.

According to the flow shown in FIG. 83, the MPU determines the number of return stages of the card 59 necessary for re-staging from time to time based on the contents of the numeral data "D'REG" and from the contents of each flag. , write to the temporary "Z・REG". And that “Z・
Returns the contents of "DN REG" for the number of stages (middle stage) only for the stage that matches the contents of "REG", and in particular, as is clear from the flow in Figure 83, "Card sending back" in the main flow of Figure 80 above, etc. It also returns each flag in the reverse order of control, for example, if there is double amikomi, it includes the contents of the FWD and KRC flags, if there is vertical double, it includes the flag twice the vertical, and also returns the flag contents of vertical. If necessary, modify the contents of the card feed direction flag in relation to facing or repeating, and set the "DN" for the current number of stages (middle stage).
Return to the flag contents corresponding to the contents of "REG". Next, after finishing the return control,
REG” and the contents of the card feed direction flag.
The card 59 is transferred to the SPU 2, thereby sending the card 59 back to the tier that matches the ``number of return tiers'' that is the content of the ``DN REG''.

Next, after clearing all bit address contents of "Data Change Memo" to "0",
After setting the CR and DS flags to ``1'' indicating card reading and data set, respectively, the first carriage run in the initial stage of reshaping is performed based on the contents of the DHP flag that stores the results of the above indexing control. If there is needle selection, the DC flag is set to "1" with data change, and if it is straight through, it is also set to "0" without data change, and in any case, the DHP flag is set to "1" with pause. is set, and the rework control of the flow shown in FIG. 83 is completed.

According to the main flow in Figure 80, the MPU:
Based on the "key scan" control in the "data input mode" while the hatch 120 is open, when the CR flag etc. is set to "1" for reshaping, the hatch 120 is then closed and the "knitting mode" is set. ”, immediately perform “card reading”, “card sending back” and “data set” control, then check the DC flag and if it is “0” without data change,
It only checks the DS flag etc. repeatedly, but if it is ``1'' indicating that data change is required, then ``data change'' is performed, and if necessary, ``card reading'', ``card sending back'' and ``data set'' control are performed. Execute. Therefore, if no needle selection is made during the first carriage run in the initial stage of reshaping,
Since the contents of all bit address parts of the "data change memo" remain as "0" data without needle selection, the knitting needles 3 act on the selection cam mechanisms 16, 16a as the carriage moves, but all The alignment is derived at position A (FIGS. 3 and 4). However, when needle selection is selected, the needle selection data based on the first card signal is stored in each bit address of the "data change memo", so knitting needle 3 is immediately set as the carriage moves. A pattern for needle selection is created. During the first carriage run in the early stages of these repairs,
Because the DHP flag is set to "1" with pause, the DC flag is not immediately set to "1" with data change.
After passing through the center, the DHP flag is reset to "0", so that carriage reversal is then enabled.

In this example, the mode of needle selection control performed by the cooperation of the MPU and SPUs 1 and 2 can be understood from the block diagram in FIG. The relationship between the transmission and reception of signals such as keys and step memos is clearly indicated.

Next, how to use this example will be explained. First, the hatch 120 is opened and the pattern selection switches SW1 and SW5 are set with the lamp L0 turned on. For example, if you want to realize a knitting pattern that repeats continuously over the entire course direction of the knitted fabric using the knitting pattern 64 arbitrarily selected on the card 59 which is the recording medium, set it to "All patterns". death,
Also, if you want to use the knitting pattern 64 selected as "Moyo A" to embody the knitting pattern only in the desired part of the knitted fabric, set it to "1 Moyo",
Also, two knitting patterns 64 selected separately for "Moyo A" and "Moyo B" on the same card 59
If you want to create a knitted pattern on the desired part of the knitted fabric using , set it to "2 also".

Next, depending on the set position of the pattern selection switches SW1 and SW5, the data input locations necessary for realizing the respective knitting patterns are sequentially called by lighting the lamps L1 to L12 each time the step key 113 is operated. Key in desired data for each of the lamps L1 to L12.

For example, it is "1 too" and "Moyo A" is included in the pixel areas numbered "1" to "25" from the 1st to the 30th row on the card 59, as illustrated in FIG. Using the knitting pattern 64 in the same vertical direction, the pattern reference position corresponding to the pixel area numbered "1" on the needle bed 2 is determined to be the right number 1 knitting needle 3,
If you want to realize a knitting pattern over 3 spaces from knitting needle #50 on the left to #50 on the right, respond to the lighting of lamp L1,
Set "1", similarly set "30" at lamp L2, set "1" at lamp L3, and set "1" at lamp L4.
At the same time, set "25", and at the lamp L5, after operating the right key 115, set "1", at the lamp L6, after operating the left key 114, set "50", at the lamp L7, set the number "50", and at the lamp L7, press the right key. After the operation of 115, set "50". Then, when the OK lamp L13 lights up, it is announced that the data input has been completed, so the key-in operation is canceled. If it is "all OK", the OK lamp L13 lights up next to the lamp L4, and data input ends.

Also, it is "2 moyo", for example, the 53rd
1 on the same card 59 as illustrated in the figure.
A knitting pattern 64 of "Moyo A" included in the pixel areas numbered "1" to "25" and "26" to "50" in the vertical direction from the row to the 30th row.
Using the knitting pattern 64 of "Moyo B" included in the pixel area of No. 1, the reference position of "Momo A" corresponding to the pixel area of No. 1 on the needle bed 2 is set to the right 1.
Select knitting needle 3 from number 50 on the left to knitting needle 3 from number 50 on the right.
At the same time, the reference position of "Moyo B" corresponding to the pixel area of number "26" is set to number 76 on the right, and it is passed between three knitting needles from number 51 to number 100 on the right. If you want to embody a knitting pattern, respond to the lighting of lamps L1 to L7 and key in the respective data, as in the case of "1 too" above.
Next, in response to the lighting of lamp L8, set the number "26", similarly set the number "50" at lamp L9, and then set "76 right" at lamp 10 and "5 right 5" at lamp L11.
1" and key in the data of "Right 100" using the lamp L12.

However, in each of the above cases, the lamp L5
The data to be keyed in when the lamp L10 is lit may be "Left 50", "Left 25", or "Right 26" instead of "Right 1", and the data to be keyed in when the lamp L10 is lit is , instead of "right 76", "right
51", and the same knitting pattern is realized as a result.

As can be understood from Fig. 54, card 59
The effective information width of the knitting pattern to be used effectively above can be freely selected according to the operator's preference. You are free to specify separate ranges, you may specify ranges that overlap with each other, and you are also free to specify completely the same range. 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. The knitting pattern 64 on the card 59 can be used in various ways. By doing this, you can realize various knitting patterns.

Next, when the above-mentioned key-in data operation is completed, the switches SW3 and SW2 are used as targets, based on the knitting patterns 64 of "Moyo A" and "Moyo B" selected on the card 59. Depending on whether you want to embody the knitting pattern in the left-right direction or in the left-right direction, operate the required switch, or select other switches.
Switch SW0, 4, 7, and 8 as desired. In particular, rubber knitting machines and chain wheels (KRC)
When knitting the well-known double knit stitch using the KHC changer, operate the double amikomi switch SW6, and when knitting the color scheme using the KHC changer, operate the forward/reverse knit switch SW8. However, for example, when editing a lace edition, the left and right hand switch SW3, 2, the horizontal fold switch SW0, the vertical fold switch SW7, and the forward and reverse switch SW8.
does not function in any way, so it is safe even if you switch it by mistake. 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.

Once the key SW operation mechanism 105, which is the key input device and needle selection mode setting device, has been operated as described above, data necessary for creating the desired knitting pattern has been entered, and the needle selection mode has been determined, Next, with the OK lamp L13 lit (the lamp L0 may be lit), the card 59, which is the desired recording medium, is mounted on the reading mechanism 68, and
First, turn off the power switch 123 and operate the manual feed dial 77 to bring the set line 67 on the card 59 to the upper edge of the insertion section 140, and then turn on the power switch 123 again. Then, operate the play start key 117.

After that, if you want to start knitting, for example, two-color simultaneous knitting after closing the hatch 120,
At least in the initial stage of knitting, move the K carriage 13 from one end of the needle bed 2 to the magnet body 4 mounted on the carriage.
2, 43 starts running further from the outer end of 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 pixel area 61 of the first stage (initial stage) are sequentially called out every time the knitting needle 3 of the K carriage 13 travels one pitch.
After the K carriage 13 travels, the knitting needles 3 are sorted into two positions A and B, front and back, and are led out as a so-called backward needle selection type.

Therefore, in this example, in order to start knitting the required pattern, knitting of the first row can be started after the K carriage 13 has run once in advance, and the pattern for selecting needles for the first row is created. Finally, the K carriage 13 is set to the desired pattern cam arrangement, and, for example, in the case of two-color simultaneous knitting, the desired knitting yarn is set and knitting begins. From then on,
All you have to do is run the K-carriage 13, and card reading, card feeding and return, etc. are automatically controlled according to the left and right rows, making it extremely easy to knit fabric that embodies the desired knitting pattern. Can be organized. In particular, when the electronic buzzer BS makes continuous beeps to notify continuous return control of the card 59, the carriage drive is stopped until the end of the notification and then resumed. , there is no disturbance in the knitting pattern.

By the way, as shown in FIG. 52, by using the knitting pattern 64 included in the pixel area from the 1st row to the 30th row on the card 59, a knitting pattern whose vertical direction is straight is made into a knitted fabric. If you want to realize it,
By pressing the keys in the reverse order to the above, set the number "30" by calling the step lamp L1 to turn on, and also by calling the lamp L2 to turn on,
It is only necessary to set the number "1", so that the column signals of the 30 pixel areas are read first at the beginning of the stacking, and the card 59 is sequentially returned one stage at a time.

In addition, in the middle of each knitting process, if the knitting pattern 64 included in the pixel area from the 1st row to the 30th row of the card 59 is used vertically as it is, the knitting pattern of one unit in the row direction is For each section, specifically, when the carriage is running, where the knitting needles 3 are sorted based on the signal of the final stage "30", the electronic buzzer BS sounds for one second to notify the worker. From this, it can be known in advance that the next carriage run will be the end of one unit of knitting pattern, which is convenient for determining when to continue the same knitting pattern or to change the pattern. In addition, if the knitting pattern is vertically facing, the electronic buzzer BS will beep to notify you that each knitting pattern is made up of a set of upper and lower facing shapes, and that the electronic buzzer BS beeps at each break. 1st step, 2nd step,
The electronic buzzer beeps when the carriage moves through stages 3, 29, 30, 29, 2, and 1, and selects the knitting needles 3 based on the signal from the 1st stage. This makes it easy to hear the end of one unit of the knitting pattern, which is convenient. Even in the case of upper and lower hands, the electronic buzzer BS sounds when the carriage is running to perform the sorting operation of the knitting needles 3 based on the signal of the "1" stage, which is the final stage, and furthermore, the upper and lower hands are If the knitting needles 3 are facing vertically, the electronic buzzer BS will sound except at the beginning of the thread when the carriage is running, where the selection operation of the knitting needles 3 is performed based on the signal of the 30th stage, which is the first stage. It's convenient.

Also, when the hatch 120 is opened in the "0" step state, or from the "D" step state when the OK lamp L13 is lit, the step key 1 can be pressed.
When the operation in step 13 returns to the initial "0" step state, the external RAM is displayed in the numeric display section 111.
This is because the content of "DN REG" for the number of rows (middle row) is displayed, and the number of rows of the pixel area of the card 59 that the sensor 92 corresponds to at that time, that is, the number of rows corresponding to the reading position J is displayed. For example, it is possible to easily check whether the card 59 is at the correct stage advance position based on the displayed content, and if it is different, it can be adjusted to match the displayed content and the 17th
Instruction field 62 of row instruction 63 with the same value as observation position K in the diagram
It is only necessary to manually feed the card 59 so that it corresponds to the above, and the correction can be made very easily. Moreover, after keying in any number data, press the back key 116.
In response, the card 59 is advanced or returned to the position J corresponding to the sensor 92, and the pixel area for the number of stages (middle stage) matches the number data. “DN・
The contents of "REG" are also rewritten accordingly to match the set number data. Therefore, the card 59 can be very easily sent to any number of stages, for example,
This is convenient when a pattern is formed from a number of rows other than the first row at the beginning of a stitch, or when a part of the knitting pattern 64 on the card 59 is omitted to realize a knitting pattern.

In this example, a first storage device (card data Separately from the memo ``correct right'' and ``correct left'' memories, there is a ``data change memo'' and ``data set memo'' which are second storage devices for bit contents corresponding to each knitting needle on the needle bed. , changes set in advance by the mode setting device according to a needle selection mode setting device for setting what kind of knitting pattern is to be realized on the knitted fabric by variously changing the knitting pattern recorded on the recording medium. In order to realize It is characterized by outputting the memory contents to the knitting needles corresponding to each bit of the transferred "data change memo" and selecting the knitting needles according to the contents. The control can be executed with ease, and the readout control operation of the stored digital electric signal from the "data change memo" related to carriage travel can be made extremely simple, for example, by changing the settings of the needle selection mode setting device. This is an extremely simple control that simply reads out the contents of each bit of the "data change memo", which is a second storage device, for each corresponding knitting needle in a one-to-one relationship. The processing speed can be sufficiently shortened, and even high-speed carriage running is satisfactory.

Next, the features of this example and modifications are summarized as follows.

1. On the knitting machine, the card is placed in the set position so that the knitting pattern on the card can be seen while the pattern is programmed, but before starting knitting the pattern, the starting position ( column) to the position where it is read by the sensor (reading position J). Therefore, an operation button (starting key 117), a card feeding device, and a control circuit thereof are provided as means for automatically feeding the card from the setting position to the reading position.

2 When performing a pattern program on a knitting machine, when setting the pattern selection on the pattern card, the starting position (first row) and end position (last row) in the row direction
By reversing the input order, the setting becomes a mode setting for the upper and lower needle orientations, but especially the left edge position (model left) and right edge position (model right) of the pattern width, as well as the needle selection range. When setting the left edge position (select left) and right edge position (select right), if you input these setting steps incorrectly, that is, if you input the right edge to the left of the left edge, the right edge and left edge A control circuit has been installed that automatically corrects the problem when replaced.

3 On the knitting machine, for example, after setting a row different from the starting position (first row) of the pattern, press the row return key 1.
When you try to start knitting by pressing 16, it is checked whether the number data is located between the start position (first row) and the end position (last row) of the pattern, and if it is outside the range. If so, a control circuit and a notification device were provided to notify the operator.

4. When programming a pattern on a knitting machine, there is a setting for "all patterns" that does not require the operator to specify the pattern reference position and needle selection range, and indexing is automatically performed using a predetermined calculation method. A control circuit was provided to write in the step memo.

5 In the case of reshaping the knitting machine, it is necessary to return the card, so for example, in the case of pattern knitting, the number of rows of unraveled fabric, and in the case of lace knitting, the length from the current to the row to be returned. A button (reset key 118) as a means for automatically returning the card by keying in the number of stages equal to the number of runs of the carriage minus 1, a card return device, and a control circuit thereof are provided.

6 When re-stitching on a knitting machine, the relationship between the yarn end and the carriage is determined from the relationship between the carriage running direction or carriage position immediately before re-stitching and the number of unraveled rows, etc., and the yarn is adjusted for backward needle selection. When the yarn end and the carriage are on the same side, the first run is made without needle selection or knitting, and on the way back, only needle selection is performed, and then the normal needle selection and knitting operation is performed. On the opposite side, a control circuit was provided so that only needle selection was performed during the first run, and normal operation resumed after the thread end and carriage were 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. The structure may be configured so that it passes through.

7 In the knitting machine, the card signal is read and the read data is sent to the pattern change instruction means (switch).
When selecting knitting needles as needle selection data by making various changes according to instructions such as SW), if the carriage reversal signal is used to calculate and output data for the next knitting row after completing one knitting row, complicated pattern changes may occur. It is assumed that there may not be enough time to give instructions. For this purpose, a data buffer for needle selection (data set memo) is provided, and a control circuit is provided for calculating and setting needle selection data for the next knitting stage during knitting of the previous knitting stage.

8 In this example, the power switch 123 is located near the manual feed dial 77, and especially when the card 59
If you want to hand-feed the machine, you can immediately turn off the power and feed it by hand, and then immediately turn on the power and start operating the system.

9 In this example, a control circuit is provided which notifies the operator by sounding the electronic buzzer BS in the event of a reading error due to a failure of the sensor 92 or the like.

10 In this example, knitting pattern 6 of card 59
Based on 4, for example, when forming a repeating pattern in the row direction or when forming a vertically facing pattern, a control circuit is provided to sound an electronic buzzer BS at each division of each unit pattern. Ta.

11 In this example, when knitting lace knitting, especially when using the L carriage based on the contents of the KL flag, control is performed to ignore the horizontal double switch SW0, etc., which is not compatible with this, and prevent the switch from entering the horizontal double needle selection mode, etc. A circuit was installed.

12 In this example, in the "0" step state where the step lamp L0 is lit, the number of stages, which is the content of "DN REG", is displayed on the number display section 111. It is easy to understand and can be dealt with very accurately.

13 In this example, when programming a pattern, when setting the pattern selection, for example, the start of the row direction of the pattern is set as 1, the end as 5, but 5,
When set to 1, the configuration was such that the signal train of the "5" stage is sent to the sensor reading position at the beginning of the stitch so that a pattern with the top and bottom orientations is created.
