Reference numeral 51 denotes a guide plate, which is provided to face sprockets 48 and 49 from below in order to guide the knitting width recording sheet 41 or the knitting pattern recording sheet 42 mounted as shown in FIG.

Mainly, in FIGS. 3, 4, and 8, 52 is a stage feed control mechanism, which can use the device shown in Japanese Patent Publication No. 50-15896. Since it is sufficient for understanding if the relationship between the rotational output and the rotational output is clear, the detailed internal structure is omitted.

That is, in the stage feed control mechanism 52, 53 is a fixed shaft 54.
A ratchet wheel 55 and a bevel gear 56 are directly connected to the hollow shaft that rotates around the hollow shaft.

Reference numeral 57 is a manual knob connected to a guide shaft 58 vertically pivoted within the machine frame 1.

A gear 59 is integrally formed with a manual knob 57 so as to mesh with the bevel gear 56. When the manual knob 57 is rotated, the hollow shaft 53 is rotated.

.

This advancing movement is transmitted to the vertically movable plate 64 via the bell crank 63, and the vertically moving plate 64 is moved upwardly against the elastic force of the spring 65.

Reference numeral 66 denotes a ratchet pawl plate, which is swingably provided on the vertically movable plate 64 and engages with the ratchet wheel 55 when the vertically movable plate 64 is raised to rotate the ratchet wheel 55 at a constant pitch.

67 is an input shaft provided in the step feed control mechanism 52, and a pinion 68 directly connected to this is a gear 69 integrated with the hollow shaft 53.
is engaged with.

Therefore, the input shaft 67 is intermittently rotated at a pitch corresponding to the rotation pitch of the ratchet wheel 55, and the rotational displacement is controlled by the senna unit output shaft 70 and The transmission is performed at a gear ratio set on the millimeter output shaft 71.

That is, for the same rotation angle of the input shaft 67, the rotation angle of the senna unit output shaft 70 is the rotation angle according to the left and right movement setting value of the centimeter setting lever 72, and the rotation angle is in millimeters. The rotation angle of the output shaft 71 corresponds to the set value of the millimeter setting lever 73 in the left-right direction.

The knitting width recording sheet 41 is made of a light-reflective material, and a large number of squares 82 are displayed on it by lines that cannot be read by the reading device described later, and the size of one square 82 is as follows in this embodiment. It is determined that the width is 44OL and the height is 3m+++, and the mold line 83 for forming the knitted fabric is recorded using a paint with poor light reflection using such squares 82 as a guide.
This corresponds to the knitting width information of the knitted work to be knitted.

The knitting pattern recording sheet 42 also has a large number of squares 84 as described above.
The pattern information of the knitting pattern to be realized in the knitting work is recorded by writing a thick diagonal pattern mark 85 in the square 84 corresponding to the knitting pattern in a manner that does not reflect light well. It is often done.

In this case, in the square 84 indicated by A in FIG.
The four horizontal sections serve as pattern information recording areas.

Reference numeral 86 denotes a slit plate, which is positioned parallel to one row of squares 84 to be optically read and scanned when the knitting width recording sheet 41 etc. is supported in a step-feedable manner, as shown in FIG. It is arranged in the machine frame 1, and the slit plate 86 is formed with 200 peaks 87 and 200 troughs 88 arranged alternately.

In addition, as shown in FIGS. 11 and 12, numbers (1)...
... (400) are added in order to obtain unit dimension values, and these will simply be referred to as peak and valley numbers.

In this example, since the number of squares 82.84 in one row of the knitting width recording sheet 41 and the knitting pattern recording sheet 42 is 100, the total length of the row is the product of 4 mm and 100, that is, 4
On the other hand, since the number of peaks and valleys of the slit plate 86 is 400, the width of each of the peaks 87 and valleys 88 is 111rIn.

In addition, 89 is a clearing hole formed at a position adjacent to the leftmost peak 87 on the left, and 90 is a clearing hole formed at a position adjacent to the rightmost valley 88 on the right side, which is vertically different from the clearing hole 89. Of these, the clearing hole 89 corresponds to the peak-to-valley number (0), and the loading hole 90 corresponds to the peak-to-valley number (401).
corresponds to

The center line B shown in Figures 11 and 12 is the recording sheet) 4

6 is positioned such that light passing through the detection groove 98 detects the presence of the peaks and troughs of the syslit plate 86 and the clear and load holes 89 and 9G.

Reference numeral 99 denotes a scanning member provided in the reading device 91, which optically reflects the presence of the forming pattern lines 83 and pattern marks 85 recorded on the knitting width recording sheet 41 and the knitting pattern recording sheet 42. There is.

10G is a second rotating wheel, 101 is a fourth rotating wheel, and a belt 102 is passed between them.
As shown in FIGS. 2, 5, and 6, the front part of a connecting frame 103 is connected with a rivet 104 in the middle of the connecting frame 103, and the sliding base 92 is connected to the upper surface of the connecting frame 103. Therefore, when the Bell HO2 was driven.

A slide table 92 is adapted to be slid along guide rods 94 and 96 together with a reading device 91.

By the way, as shown in FIG. 6, the first rotating wheel 23
is supported to rotate around a fixed ring 105 vertically installed in the machine frame 1, and a third rotating ring 10G is located below the first rotating ring 23 and rotates around a fixed shaft 1050. It is provided so that it can rotate.

The first rotating wheel 23 and the third rotating wheel 100 are connected by a clutch mechanism 106.

This clutch mechanism 106 is configured by applying the feed section of a conventionally known punch card mechanism, and usually includes a large number of retainers that are urged to move toward the center of rotation by a spring band 107. The eccentric elliptical follower rotary plate 109 is rotated by the first rotary wheel 23 through frictional contact with the follower rotor plate 108. A third rotary ring 100 that is integral with the plate 110 by being engaged with either side edge of a pair of side protrusions 110a provided on the plate 110.
It is intended to be transmitted to

That is, although the clutch mechanism 106 always transmits the rotational force of the first rotating wheel 23 to the third rotating wheel 100.

When the first rotary wheel 23 is reversed, the power is not transmitted to the third rotary wheel 100 until about half a rotation from the start of the reverse rotation, and then the power is transmitted.

This is because when the carriage 8 is reversed, the knitting width recording sheet 41 or the knitting pattern recording sheet 42 is fed, as will be described later, but after the feeding is completed, the third rotary wheel 100 is rotated. Starting, i.e. reading device 9
1 starts sliding.

2 and 6, 111 and 112 are inserted into left and right holes 114 and 115 of a support block 113 attached to the lower surface of the connecting frame 103 so as to be able to move left and right against a predetermined frictional force. interposed between them is a compression spring 116 set to a spring force that pushes out the other when one is retracted.

Therefore, the belt 27 runs in conjunction with the sliding movement of the carriage 8, and its movement causes the first rotating wheel 23. Clutch mechanism 106
゜It is transmitted to the third rotating wheel 100 and the belt 102, and thereby acts on the reading device 91 when, for example, the reading device 91 is moved to the right in FIG. 6 and the buffer rod 112 collides with the stopper portion 117. Alleviate the impact.

After the buffer rod 112 contacts the stopper portion 117, the sliding base 92 cannot move any further, but in this case, the engager 108 in the clutch mechanism 106
A third rotating wheel 100 that frictionally slides against the
The rotational force from the first rotating wheel 23 is no longer transmitted.

In addition, when the reading device 91 is moved to the left in FIG.
11 comes into contact with the metal fitting 45, and its effect is the same as described above.

In FIGS. 1, 3, and 13, 118 is a stage number display device, 119 is a needle number display device, and 120 is a left needle number display device, the light emitting part of which is composed of segment type LEDs. ing.

121 is a senna unit setting lever for setting the number gauge, 1
Similarly, reference numeral 22 is a setting lever in millimeters, and these levers can be moved along relief grooves 123 and 124 provided on the soil surface of the machine frame 1, and there are also centimeter unit setting levers in the vicinity of each relief groove 123 and 124. Unit scale 125 and millimeter scale 1
26 is displayed.

In this case, although detailed illustration is omitted, the senna unit setting lever 121 and the millimeter unit setting lever 122 for setting the number gauge are connected to the contact changeover switch 128, respectively.
129 are now interlocked, and the contents of the contacts according to the respective sliding settings are shown in the scale gauge circuit 127 in Fig. 13.
Here, the two are combined and a number gauge signal S1, such as 13 cm 2 mm, etc., is output as a digital code.

130 is a band-shaped code line, which is connected to the peak/valley detector 97 in the reading device 91. This is for electrically connecting the scanning member 99 and various electric circuits shown in FIG. 13 mounted in the machine frame 1.

Reference numeral 131 denotes a front lid provided to open and close an opening for attaching and detaching the knitting width recording sheet 41 and the like and inspecting the scanning member 99.

In this example, the row number gauge information is expressed as a length value per 60 rows, the stitch number gauge information is represented as a length value per 40 stitches, and the knitting width recording sheet 41 Since the knitting work pattern, which is scaled from the actual size to the size 16, is written on the forming pattern line 83, the levers 72 and 73 of the stage feed control mechanism 52 are set to the unit scale 80, for example. When the scale is adjusted to the "6" scale and the "0" scale of the unit scale 81, the gauge information of the 60 steps becomes 60 m, and the sheet is moved through the control mechanism 52 by one operation of the ratchet mechanism 60. 41 is fed in steps of 0.5 ttan, which corresponds to the vertical size of the actual stitch.

Next, the operation of the above structure and FIGS. 13 and 14 will be explained.

In this embodiment of the present invention, when trial knitting is performed prior to knitting a knitted work, the pattern information recorded on the striped pattern recording sheet 42 is simultaneously read over all rows of the knitted pattern at the same time as the trial knitting. , this is stored in the second storage device 132
Then, in the process of forming the knitted fabric while reading the knitting width information recorded on the knitting width recording sheet 41 in knitting the knitted work, the second storage device 132
The aim is to realize a knitted pattern as the knitted fabric is formed by reading out pattern information from the knitted fabric.

By the way, the configuration of the storage area of the second storage device 132 is as shown in FIG. Y address (0) in the vertical direction (column direction) indicated by arrow Y
It is configured to have 128 bits from number to (127).

Now, before we start the trial knitting, first of all, striped pattern recording sheet 4.
2 is attached to the stage feeding mechanism 40, and the feeding hole 47 in the lower part of the sheet 42 is engaged with the sprocket 48, 49.

On the other hand, the scanning member 99 scans the squares 84 of the striped pattern recording sheet 42.
Since it is preferable to scan approximately the center of
Adjust the millimeter unit setting lever 73 to the 10" scale of the millimeter scale 81, and then manually rotate the manual knob 57.

Then, the striped pattern recording sheet 42 has 60 stages 6 of provisional gauge information set for the stage feed control mechanism 52 by the centimeter unit setting lever 72 and the millimeter unit setting lever 73.
The first scanning stage of the striped pattern recording sheet 42 corresponds to the scanning member 99 with the row of the square 84 located one stage below.

In this way, since the striped pattern recording sheet 42 is manually fed finely at a pitch of 5 mm, the approximate center of the square 84 can be easily aligned with the scanning member 99.

In the subsequent trial knitting, the striped pattern recording sheet 42 must be fed by one step in the grid 84 for each course of sliding of the carriage 8, that is, by 3 m, in order to accomplish this.

Set the centimeter unit output shaft 72 in the stage feed control mechanism 52 to the "18" scale of the centimeter scale 80, and align the millimeter unit setting lever 73 to the "0" scale of the millimeter scale 81.

Then, the striped pattern recording sheet 42 has temporary gauge information of 60.
The ratchet mechanism 6 is set to stage 180tIrlIL.
When the stepped solenoid 61 at 0 is excited on both sides by two pulses, the step is moved at a pitch of 3 m corresponding to (1.5 m× 2 ).

Next, in order to read the pattern information recorded on the striped pattern recording sheet 42 during trial knitting, first the data selection switch 133 is
is switched to fixed contact a corresponding to the pattern information reading function.

Then, the function circuit 135 receives a signal from the signal source 134 and generates a function selection signal, sets the pattern information writing control circuit 136 to an operable state, and writes the second storage device 1
While clearing all the memory contents of 32, transmission line 13
7 to the counter control circuit 138.

Accordingly, the counter control circuit 138 supplies a clear signal to the Y address counter 140 via the transmission path 139 to return it to Y address (0), while receiving, for example, a carriage inversion signal to be described later. In some cases, a pattern information writing mode is set in which two continuous pulses are supplied to the step feed control circuit 142 via the transmission line 141 to turn on and off the step feed solenoid 61 twice each time. .

On the other hand, the count contents of the Y address counter 140 are also supplied to the display control circuit 143 and displayed on the stage number display device 118, so in this case, the display value of the stage number display device 118 is (0 ).

Now, in the above condition, slide the carriage 8 to 60 stages 4.
In order to obtain the 0th gauge information, a well-known trial knitting is performed to knit a knitting sample (trial rope piece) with, for example, 140 rows and 60 or more stitches.

By the way, in the carriage reversal detector 36, the belt 2
Each time the carriage 8 slides in reverse, the mover 38 in frictional contact with the carriage 8 moves between the solid line position and the two-dot chain line position in FIG.
The inverted signal generation circuit 148
The inverted signal S4 is supplied to the counter control circuit 138 from the counter control circuit 138.

Therefore, when the carriage 8, which is positioned at the end of the needle bed, runs in order to start trial knitting, the counter control Two pulses from circuit 138 are provided to stage control circuit 142.

As a result, when the stage feed solenoid 61 is energized twice, the vertical moving plate 64 is moved up and down twice, the knitting pattern recording sheet 42 is advanced by one stage: 3+o++, and the square 84 is scanned. Approximately the center of the first stage to be scanned is the scanning member 99.
corresponds to

Further, one pulse is supplied to the Y address counter 140 from the counter control circuit 138 which is in the pattern information writing mode in response to the inversion signal S4, and the count value of the counter 140 changes from (0) to (1). will be changed to

Thereafter, due to the sliding movement of the carriage 8, the belt 27 is run and the first rotating wheel 23 and the second rotating wheel 24 are rotated as described above, and after the clutch mechanism 106 has a play of about half a rotation, , the third rotating wheel 100 and the fourth rotating wheel 101 to which the belt 102 is passed also rotate.

Then, as the belt 102 runs, the reading device 91 moves rightward as the carriage 8 slides, for example, rightward, and at this time, the scanning member 99 scans the first row of the knitting pattern recording sheet 42 and at the same time A detector 97 scans the slit plate 86.

When the peak/valley detector 97 scans the slit plate 86, the photointerrupter circuit 144 outputs a position pulse S2 at the boundary between the peak 87 and the valley 88, which is counted by the up/down counter 145.

The counted value is then supplied to the pattern information writing control circuit 136.

On the other hand, when the scanning member 99 passes the pattern mark 85 recorded on the square 84, it generates a low level sensor output and supplies this to the signal generating circuit 146.

Then, this signal generation circuit 146 supplies the pattern pulse S3 which becomes bi-level at the pattern mark 85 to the pattern information writing control circuit 136 via the transmission line 147.

Incidentally, since the peaks 87° and valleys 88 of the slit plate 86 and the squares 84 of the knitting pattern recording sheet 42 have a relative positional relationship as shown in FIG. Generate pulse S2.

Therefore, for example, when the carriage 8 slides to the right, when the scanning member 99 starts to enter the square 84a, the count content of the up/down counter 145 is changed to the peak/valley number (1
The relationship is (153), which is the same as 53), and (156) just before the square 84a is completed.

If the pattern mark 85 is present in the square 84a during the counting increase from (153) to (156), it is transmitted from the scanning member 99 to the transmission line 147 via the signal generating circuit 146.
If the pattern pulse S3 is output in the square 84,
The pattern pulse S3 corresponding to the pattern mark 85 in a is calculated from the count value (153) of the up/down counter 145 to (15
The second storage device 132 corresponds to block (23) in which the increase up to 6) is one block.
X address (23) corresponding to block (23) inside
number is memorized.

In this way, as can be understood from reference to FIG. ) to (248), and by sliding to the left, it decreases from (248) to (153). This is divided into 24 blocks, so that the addition or subtraction of 4 counts in 4 counts is considered as one unit block, and the blocks (23) to (0) are divided into 24 blocks, respectively. This serves as a signal to sequentially designate X addresses (23) to (0) of the storage device 132.

Therefore, by sliding the carriage 8 one course to the right as described above, the pattern pulse S3 due to the pattern mark 85 for one row recorded in the mark display area A is transferred to the X of the second storage device 132. Writing is performed to X addresses (23) to (0) in address (1).

When the peak-to-valley detector 97 scans the loading hole 90 located at the right end of the slit plate 86, the position pulse S2 from the photointerrupter circuit 144 is received by the load pulse from the up/down counter 145. forcibly even if the count value is incorrect (401)
Next, when the carriage 8 is reversed from rightward sliding to leftward sliding as described above, the inverted signal/generation circuit 148 again outputs the inverted signal 84, which is sent to the counter control circuit 138. Two pulses are supplied from the counter control circuit 138 to the stage advance control circuit 142, and one pulse is also supplied to the X address counter 140 at the same time.

As a result, the count content (1
) to (2) to designate the X address (2) of the second storage device 132, and at the same time
1 is excited twice by the step feed control circuit 142 which receives the above two pulses, and the striped pattern recording sheet 42 is fed one step.

As the carriage 8 subsequently slides to the left, the pattern mark 85 recorded on the second row of the striped pattern recording sheet 42 is read by the scanning member 99.

On the other hand, the up/down counter 145<d peak/valley detector 97
As it scans the slit plate 86 from the right end to the left, the count value is subtracted one by one from (401) each time the position pulse S2 is received.

Therefore, while the scanning member 99 moves leftward in the mark display area A, the pattern pulse S3 outputted from the signal generation circuit 146 is transmitted from X address (0) to (23) among X addresses (2). It will be remembered.

When the peak and valley detector 97 scans the clear air hole 89 at the leftmost end of the slit plate 86, the photointerrupter circuit 1
A clear signal is generated from 44 to forcibly set the up/down counter 145 to (0) even if the count does not reach (0).

In the final stage of the reading operation of the pattern information recorded on the striped pattern recording sheet 42 by the pattern mark 85, the scanning member 99 scans the end bit mark 149 recorded on the striped pattern recording sheet 42 as shown in FIG. As shown, the mountain and valley numbers (38
9) to (392), the pattern pulse S3 in response to the reading is supplied from the signal generation circuit 146 to the pattern information writing control circuit 136.

Then, the pattern information writing control circuit 136 determines that the pattern pulse S3 when the count content of the up/down counter 145 is (389) to (392) is a reading completion signal, and transfers the pattern information to the transmission line 15.
0 to the counter control circuit 138.
1 inversion signal generating circuit 1 despite the sliding of the carriage 8 for trial knitting which is continuously carried out thereafter.
No response to inverted signal S4 from 48.

The stage feeding operation by the stage feeding lens 61 and the addition operation of the X address counter 140 are stopped.

All of the pattern information recorded on the striped pattern recording sheet 42 in this way is stored in the second storage device 132 during the trial knitting process.

Next, the organization of a knitted work will be explained.

First, the knitting width recording sheet 41 is attached to the step feed mechanism 40 in the same manner as the knitting pattern recording sheet 42, and the manual transparent knob 5 is attached.
7 to set the start position of the first step 9.

On the other hand, the actual vertical dimension of the 60th row of stitches and the actual lateral dimension of the 40th stitch in the trial knitting obtained by the above-mentioned trial knitting are measured.

For example, the vertical dimension is 13 cm 5 mm, or 135 m.
If this is the case, set the senna unit setting lever 72 to the centimeter scale 80, 113, and set the millimeter setting lever 73 to the millimeter scale 81, 5.

On the other hand, if the horizontal dimension is 13 cm and 2 mm, that is, 132 mm, set the senna unit setting lever 121 to the "113" mark on the centimeter scale 125, and move the millimeter setting lever 122 to the "2" mark on the millimeter scale 126. Align with the scale.

Then, in this embodiment, since the forming pattern line 83 is recorded on the knitting width recording sheet 41 at a scale of I, the senna unit setting lever 72 and the millimeter unit setting lever 73 are set as described above. By energizing the stage feed solenoid 61 with one pulse, the knitting width recording sheet 1 is fed by 1,125+on stages corresponding to the actual vertical size of the stitches every time the carriage 8 slides one course. do.

On the other hand, based on the settings of the senna unit setting lever 121 and the millimeter unit setting lever 122, the stitch number gauge signal S1 corresponding to the width dimension of 4 stitches of 13 cm and 2 mm is constantly given to the arithmetic circuit 151 from the stitch number gauge circuit 127. It will be done.

Then, for knitting the knitted fabric, the data selection switch 133 is set to the fixed contact piece corresponding to the knitting width information reading function.

Then, the function circuit 135 outputs a function disabling signal to put the pattern information writing control circuit 136 into a disabled state.

While the knitting width information writing control circuit 152 is enabled, the counter control circuit 138 is enabled in the knitting width information writing mode, and in response to the 1 inversion signal 84, - pulses are sent each time to the stage feed control circuit. 142, and the mode is changed so that it does not affect the Y address counter 145.

After this, the carriage 8 is slid back and forth to knit the knitted work.

In this case as well, each time the sliding direction of the carriage 8 is reversed, the reversal signal S4 is output from the reversal signal generation circuit 148, and based on this, a single pulse is generated from the counter control circuit 138 to excite the step shift solenoid 61. Therefore, the knitting width recording sheet 41 is fed in steps of 1.125+o++.

Now, in the formation, the peak and valley detector 9 is linked to the carriage 8.
When the slit plate 86 and the knitting width recording sheet 41 are scanned by the scanning member 7 and the scanning member 99, if the carriage 8 is sliding to the right as described above, the position pulse S2 output from the photointerrupter circuit 144 is used as an up/down counter. 14
5 performs addition and counting, and supplies the counted contents to the knitting width information writing control circuit 152.

If, as shown in FIG. If the left outline 83a of the molding die line 83 exists at the positions of the peak and valley numbers (100) and (101) of the slit plate 86, the scanning member 99 reads the left outline 83a and produces a υ signal. The pattern line pulse S6 output from the generation circuit 146 is supplied to the knitting width information writing control circuit 152.

The count contents of the up/down counter 145 at this point are equal to the peak and valley numbers (100) and (101),
When the count value signal is given to the knitting width information writing control circuit 152, the control circuit 152 causes the scanning member 99 to move to the right.

Alternatively, at the time when the leftward movement is stopped, a write control operation is executed to store in the first storage device 153 the count contents of the counter 145 where the first and last pattern line pulses S6 in the current travel occurred. Therefore, in the above case, the count content (100) of the counter 145 is stored in the first storage device 1.
53.

And this stored count value, that is, the peak and valley number (100)
is given to the arithmetic circuit 151.

Then, the arithmetic circuit 151 converts the number of stitches required for knitting into the size of the knitted stitches based on the peak-to-valley number value, which is the knitting width information received from the first storage device 153, and the stitch count gauge signal S1 received from the stitch count gauge circuit 127. The calculation operation is performed, and the number of stitches obtained as a result is stored in the display storage circuit 154.

For example, the arithmetic circuit 151 calculates the center line B of the recording sheet 41, that is, the peak-to-valley number (200) of the slit plate 86, based on the stored content rloOJ from the first storage device 153.

(201-100=10f), and since the width dimensions of the peaks and valleys of the slit plate 86 are 11rar1, (101XIX22) 202 mm) and the actual size of the knitting work to be knitted, then calculate the stitch number gauge signal S1 of the stitch number gauge circuit 127 (for example) and the number of knitting needles 3 necessary for knitting the knitted work. In other words, calculate the needle number counting to the left from number "0", especially the above 61.1212.
If there is a fraction below the decimal point, as in
54.

The contents stored in this display storage circuit 154 are “
62” is displayed on the left needle number display device 12 via the display circuit 155.
It is given to 0 and displayed numerically as "62".

Further, the scanning member 99 moves leftward or rightward to touch the mold line 8.
At the time when the right outline 183b of No. 3 is read, the count contents of the up/down counter 145 are the peak and valley numbers (300) and (30
1), which are equal to (300) and (301), and when these are given to the knitting width information writing control circuit 152, the circuit 15
2 is the above-mentioned write control operation, and the peak-to-valley number (301) is stored in the first storage device 153.

Therefore, the arithmetic circuit 151 calculates the center line B of the recording sheet 41, that is, the peak-to-valley number (200) of the slit plate 86, based on the stored content r301J from the first storage device 153.

Calculate (301-200=101) so that the boundary of (201) is the standard of "0", and do the same as above to calculate the number of knitting needles 3 required for knitting the knitted work.In other words, the number "
The needle number counted to the right from "0" is calculated as "162", and this is stored in the display storage circuit 154 as the right needle number.

This stored content "62" is then given to the needle number display device 119 via the display circuit 155 and displayed numerically as "62".

In this way, as the scanning member 99 moves in conjunction with the movement of the carriage 8, the forming pattern line 8 of the knitting width recording sheet 41
3 gives one knitting width information, and the required number of stitches on the needle bed 2 is indicated by the needle number display by the needle number display device 119 and the left needle number display device 120. By pulling out the knitting needles 3 existing within the displayed needle number section to knitting holding positions involved in knitting, knitting can be performed with the necessary knitting width.

Note that the left and right outlines 83a of the forming pattern line 83 are recorded on the knitting width recording sheet 41 as the number of knitting rows progresses.

When the interval between the needles 83b and 83b changes, the buzzer 156 starts to sound, and the sound allows the operator to confirm the change in the needle number display by the needle number display device 119 and the left needle number display device 120. .

The knitting operation is performed based on the changed needle number.

In addition, 157 is a molding selection switch. 158 is a molding selection circuit, 159 is a signal source, and as mentioned above, the molding line 8
3, when reading the left outline line 83a and the right outline line 83b with center line B (boundary between peak and valley numbers 2oo and 2o1) in the middle, set the molding selection switch 157 to the fixed contact piece 157A.

In addition, when forming one knitted fabric using the forming pattern line recorded in the left half area based on the center line B of the knitting width recording sheet 41, set the forming selection switch 157 to the fixed contact piece 157L, and set the forming selection switch 157 to the fixed contact piece 157L. When performing the molding using the molding line recorded in the half area, the molding selection switch 157 is set to the fixed contact piece 157R.

Due to the action of this forming selection circuit 158, the knitting width information writing control circuit 152 which inputs the selection signal can control the scanning member 9.
9, the write control operation for storing in the first storage device 153 the count contents of the counter 145 where the first and last pattern line pulses S6 were generated during each run, that is, the peak and valley numbers, is switched, For example, if the selection switch 158 is set to the fixed contact piece 157A, the counter 1
The first and last determinations of the pattern line pulse S6 are made over the entire range from peak and valley numbers "1" to r400J, which is the counting content of 45, and when the switch 158 is set to the fixed contact piece 157L, The beginning and end of the pattern line pulse S6 is determined only within the range of the peak and valley numbers "1" to r200J, which is the count content of the counter 145. Furthermore, if the switch 158 is set to the fixed contact piece 157R, Peak and valley numbers r201J to r40 that are the count contents of the counter
The first and last of the pattern line pulse S6 is determined only within the range of 0J, and each of the first and last counters 1
45 is stored in the first storage device 153.

In either case, the needle number corresponding to the left pattern line 83 on the sheet 41 is displayed on the left needle number display device 200, and the needle number corresponding to the right pattern line 83 is displayed as a needle number. This is the relationship displayed on device 119.

In the above, the display memory circuit 164 and the display circuit 1
55. Needle number display device 119 and left needle number display device 1
20 corresponds to the first output device 160 of the present invention.

Now, as mentioned above, while forming the knitted fabric while reading the forming pattern line 83 recorded on the knitting width recording sheet 1, if you want to knit the knitting patterns at the same time, press the data selection switch 133 to select the pattern information. Set to fixed contact piece C that corresponds to the reading function.

As a result, one clear pulse is output from the function circuit 135, which is sent to the Y address counter 1 via the counter control circuit 138 which is in the pattern information read mode.
40, clearing it to the (0) state.

Of course, even in such a setting, the pattern information writing control circuit 1
36 is disabled, and the knitting width information writing control circuit 152 remains enabled, but the successive control circuit 161 is enabled for the first time here. After such settings, pattern knitting is started. When the carriage 8 is moved away from the end of the needle bed.

At the beginning, in response to the inverted signal S4 outputted from the inverted signal generation circuit 148, the Y address counter 14G changes to the count content (1), and the X address of the second storage device 132 (1).
) number.

Then, the 24-bit design information stored in the 24 X addresses at the X address (1) is sent to the read control circuit 161.

In this state, the pattern information of the X address (1) is linked to the sliding movement of the carriage 8 in the order from the X address number (0) to (23), or in the reverse order (this order is (depending on the direction) from the read control circuit 161.

That is, to explain this in detail, if the encoding disk 30 rotates in the direction of arrow 162 in conjunction with the leftward movement of the carriage 8, the needle pulse sensor 34 rotates as the encoding disk 30 rotates in the direction of arrow 162. At the same time as the pulse S7 is output, the code sensor group 35
X address signal S8 expressed in binary code from
are repeatedly output in order from (0) to (23) (in the case where the carriage 8 slides to the right, the order is reversed).

In this case, as shown in FIG. 9, the knitting needles 3 are divided into 24 blocks, and the knitting needles 3 in the block are numbered from (0) to (23) so as to correspond to the X address.
As shown by line 165, when the needle selectable position of the left needle selection control device 15 reaches the position (0) of the knitting needle 3 (rose) 7a, the X address signal becomes (0). S8 is output, and the needle pulse S7 is output in synchronization with the needle selectable position corresponding to each knitting needle 3. Both signals 87 output in this way
．． S8 is also supplied to latching circuit 163.

For example, when the X address signal S8 (0) is supplied to the latching circuit 163, it is latched using the needle pulse S7 as a trigger and is held until the next needle pulse S7 is received. X address (0) Pattern information inside the hook Select digital code 11
A pattern pulse S3a corresponding to " is output, and is simultaneously supplied to the solenoids 16 of the left row needle selection control device 15 and the right row needle selection control device 18 via the amplifier 164 and appropriate power transmission lines.

Then, as shown in FIG. 9, the pan 7a of the knitting needle 3 (0) which has reached the needle selection possible position is moved in the direction of the needle selection position path 21.

Of course, if there is no pattern pulse S3, the other path 22
enters in a straight line.

Thereafter, the same operation is repeated using 24 knitting needles as a unit, and a striped pattern corresponding to -courses is realized.

When the carriage 8 is reversed from the leftward sliding to the right as described above, the counter control circuit 138, which is in the pattern information read mode, operates and responds to the input of the 1 inversion signal S4. Each time, the count contents of the X address counter 140 are
Add in increments of 1.

Since one pulse is supplied to the stage feed control circuit 142, the counter 140 first advances to (2), so the pattern information at the X address (2) in the second storage device 132 is read out by the read control circuit. 161, and from there, the pattern information from the X address number (23) to number (0) is repeatedly read out in this order.

Here, read control circuit 161. Latching circuit 163. The left row needle selection control device 15 and the right row needle selection control device 18 correspond to the second output device 166 of the present invention.

In addition, in the operation of realizing the striped pattern as described above, the count contents of the X address counter 140 based on the inversion signal S4 generated every time the carriage 8 slides are reversed, and the count contents of the X address counter 140 are displayed on the stage number display device 118, so that the operator can By looking at the number, you can know which X address is being read out, and from this, for example, you can tell that you have finished reading all the rows of one stitch pattern (the row number of the last row of a striped pattern is Since the number of rows remains displayed on the row number display device 118 when the pattern information writing is finished, the total number of rows can be easily grasped before switching the data selection switch 133 to the contact piece C, and as the pattern knitting progresses, the number of rows remains displayed on the row number display device 118. If you indicate this, reading of all stages will be completed),
When that happens, do you go back to the first stage and repeat?

Or, it can be used as a guideline when changing the embodiment of the striped pattern, such as stopping at the middle stage.

In addition, in the operation of attaching the knitting width recording sheet 41 to the row feeding mechanism 40 and reading the knitting width information, the knitting width recording sheet 41 may be manually fed when resetting the knitting due to a knitting failure, etc. Alternatively, if you wish to return it, do so by manually rotating the manual knob 57.

Also, if the pattern is being knitted, the 1 knit width recording sheet 41
Along with forwarding or returning, forward button 167 or return button 1
When 68 is pressed, the continuous pulse generator 169 generates corresponding addition or subtraction pulses at regular intervals while each button is operated, and this is transmitted via the counter control circuit 138 which is in the pattern information read mode. X address counter 1
40.

Then, the X address counter 140 adds "1" for every addition pulse input when the forward button 167 is pressed, and counts "1" for every subtraction pulse input when the return button 168 is pressed.
1" at a time, and when the change in the counted contents corresponds to the change in the step number displayed by the step number display device 118 and the step number changed by the manual knob 57, release the push button 167 or the return button 168. For example, at that point, the addition/subtraction count of the Y address counter 140 is stopped.

In addition, 17G is a reset circuit, and when the reset button 171 is pressed, a reset pulse is generated, and by supplying this to the counter control circuit 138 which is in the pattern information read mode, the Y address counter 140 is cleared to (0). Ru.

With this, for example, when the same striped pattern is repeatedly realized in the row direction, restarting can be carried out very easily.

In this example, the distance between the needle selection possible position 165 of the left and right needle selection control device 15° 18 in the carriage 8 and the carriage center line is, for example, 4.5 rr, which is the arrangement pitch of the knitting needles 3.
The distance is set to an multiplied by (24), which is one unit division of the striped pattern, so that the striped pattern does not shift horizontally when the carriage 8 slides to the right or left. It is something that is taken into account.

By the way, only on the knitting width recording sheet 41, which is the first recording medium, instead of the vertical 3 WIIL and horizontal 4 TIan squares, you may write in the usual 5 square square squares, and use this as a guide to record B size knitted fabric. The pattern line 83 representing the work pattern may be easily extracted.

As is clear from the embodiments described above, the present invention has a first recording medium which records the knitting width information of the knitted work to be knitted, and a second recording medium which records the pattern information of the striped pattern to be embodied in one knitted work. A step-feeding mechanism for feeding a recording medium and a first or second recording medium, which are attached to each other so as to be exchangeable, at an appropriate pitch; and a first or second recording medium attached to the step-feeding mechanism. a reading device that scans the information on the medium by a common scanning member; a first storage device that stores the knitting width information read by the reading device; and a first storage device that stores the knitting width information read by the reading device; a second storage device that stores the information across the knitting device; and an arithmetic circuit that calculates the number of stitches necessary for knitting the fabric by converting it into the size of the knitted stitches in response to the knitting width information stored in the first storage device. a first output device that outputs the stitch number information outputted from the arithmetic circuit as a signal necessary for forming the knitted fabric; and a first output device that outputs the stitch number information output from the calculation circuit as a signal necessary for forming the knitted fabric, and a The present invention is characterized in that it also includes a second output device that outputs a signal necessary for realizing the pattern on the read-out knitted fabric.

Therefore, according to the present invention, pattern information can be stored in advance in the second storage device prior to knitting a knitted work by using a common scanning member for knitting width information, In the process of forming the knitted fabric while installing the recording medium and reading the knitting width information, the pattern information can be immediately read from the second storage device, and this allows the striped pattern to be formed at the same time as the knitted fabric is formed. can be implemented as desired, which is extremely convenient.

In particular, the first and second recording media are configured to be mutually replaceable and attached to the same stage feed mechanism, and the information on the image recording media is read by the same common scanning member. Because of this, devices can be shared and the configuration can be simplified.

Furthermore, for example, it is possible to freely read the pattern information recorded on the second recording medium at the trial knitting stage, which eliminates the need for special operations just for reading the pattern information. This also makes it possible to rationally perform a series of organizing operations.
