130c is short-circuited, an output signal "0" is generated, and when the endless belt 28 is moved from the right side in the direction of arrow A opposite to the direction of the arrow A, the sliding member 130
The output signal rlJ is generated when the short circuit between the contacts 130b and 130c caused by the contacts 130b and 130c is released.

The output signal of this inversion detector 130 is transmitted to the inverter circuit 1
32 and the differentiating circuit 133 as one input signal of the OR circuit 134, and the differentiating circuit 135
The OR circuit 134 generates a positive output pulse each time the carriage 7 is reversed.

The output pulse from this OR circuit 134 is given to the input terminal (2) of a constant width pulse generation circuit 136, and the constant width pulse generation circuit 136 carries out a constant width pulse from the output terminal O every time a pulse is given to the input terminal (2). The signal is generated as an inverted signal, and this is supplied as the other input signal to the AND circuit 129.

On the other hand, the output signal of the light receiving element 61 is transmitted to the inverter circuit 1.
37, and the output signal of the inverter circuit 137 is given as an input signal to a visual notification device 138 such as a lamp.
When the signal "l" is given as an input signal, it is given as an input signal to an auditory notification device 140 such as a buzzer via a single pulse generation circuit 139 which generates an output pulse of a predetermined width each time.

Next, the operation of this embodiment configured as above will be explained.

When pattern knitting is to be performed using the recording sheet 46, first the contact pieces 84o-842 of the pattern knitting switch 84 are selectively closed.

Then, a signal "l" is generated at the movable contact piece 84o of the pattern knitting switch 84, which is given as one input signal of the AND circuit 129, and is also given as one input signal of the AND circuit 83, and is further given as a single pulse. Generation circuit 1
The single pulse generating circuit 114 generates one output pulse from the output terminal 0 and applies it to the reset terminal H of the counter 112, thereby resetting the counter 112.

In addition, the repeat switch 103 has contact pieces 103o-103.
, the interval is closed and repeat is disabled.

After that, the movable contact piece 92o of the pattern number selection switch 92
When you operate the fixed contact piece 92 to 92n and touch the fixed contact piece corresponding to the desired pattern number of the recording sheet 46, for example "7", and then operate the start button, the encoder 91 starts from the output terminal 0. Numerical content "7" corresponding to the selected pattern number is generated as an output signal.

On the other hand, if the recording sheet 46 is mostly wound up by the take-up roller 35 and the embedded base 59 corresponds to the starting end of the recording sheet 46, and the count content of the counter 94 is "O", for example, then the comparison circuit 93 is the numerical content of input terminal Ia “7
” and the count content “0” of the input terminal Ib, and since the difference is positive, the output signal “1” is output from the positive output terminal Oa.
will occur.

Since this output signal "1" is given to the input terminal (2) of the high-speed continuous pulse generation circuit 108, the high-speed continuous pulse generation circuit 108 starts to continuously generate output pulses at a high speed from the output terminal O. , this output pulse is given to the normal rotation input terminal Ia of the pulse motor control circuit 104 via the OR circuit 105, and is further applied to the OR circuit 10.
7 to the drive input terminal Ic of the pulse motor control circuit 104.

Therefore, the pulse motor control circuit 104 rotates the pulse motor 37 by a predetermined angle in the direction of arrow C, which is the forward rotation, every time a pulse is applied to the forward rotation input terminal Ia and the drive input terminal Ic. Arrow direction (
(forward movement) intermittently one step at a time.

In this way, when the recording sheet 46 is fed forward, the light receiving element 60 encounters the count scale attached to the pattern number counter display section 49 every time the recording sheet 46 corresponds to the front stage of a plurality of sections. Since a count signal "l" which is an output signal is generated, the signal "l" is applied to the input terminal (2) of the single-shot pulse generation circuit 98 via the inverter circuit 97 each time, and the single-shot pulse generation circuit 98 outputs the output terminal O. - output pulses are generated each time.

Therefore, since the output signal "1" from the positive output terminal Oa of the comparison circuit 93 is given as one input signal to the AND circuit 95, the AND circuit 95 receives the output pulse from the single pulse generation circuit 98. is applied to the addition input terminal Ia of the counter 94, and the count contents of the counter 94 sequentially change to "1", "2", . . .

Thereafter, the light receiving element 60 detects the count scale 4 of the pattern number "7" corresponding to the front stage of the seventh section of the recording sheet 46.
9a and the count content of the counter 94 becomes "7", the numerical content of the input terminal Ia of the counter 94 becomes "7".
” and the count content “7” of input terminal Ib match and the difference becomes zero, so the output signal “l” from positive output terminal Oa
'' disappears, and therefore the forward feeding of the recording sheet 46 by the pulse motor 37 is stopped.

As a result, one end of the light guide member 58 in the embedded base 59 corresponds to the "0" stage, which is the front stage of the seventh section.

At this time, the light receiving element 61 is connected to the position scale display section 50.
The visual notification device 138 is supplied with the input signal "l" via the inverter circuit 137 and lights up, Auditory notification device 140 includes inverter circuit 1
37 and a single pulse generation circuit 139, a pulse of a predetermined width is applied as an input signal, and the sound is generated for a predetermined time.

After that, the worker moves to the carriage 7 to start knitting the pattern.
When the endless belt 28 is moved, for example, from the right end on the needle bed 2 to the left, that is, in the direction of the arrow A, the endless belt 28 also moves in the direction of the arrow A, and the sliding member 130a sliding thereon also moves in the direction of the arrow A. The inversion detector 130 inverts the output signal from "1" to "0", and one constant-width pulse is sent from the constant-width pulse generation circuit 136 to the carriage inversion. Occurs as a signal.

Since the signal "1" of the movable contact piece 84o of the pattern knitting switch 84 is given to the AND circuit 129 as one input signal, the AND circuit 129 passes the carriage inversion signal, and the AND circuit 110 and 105
Normal rotation input terminal I of the pulse motor control circuit 104 via
a, and is further applied to the drive input terminal Ic of the pulse motor control circuit 104 via the OR circuit 107, and the pulse motor 37 advances the recording sheet 46 by one step, so that each end of the light guide member 58 The section is the first step.
Corresponds to stage 1.

Further, the carriage inversion signal is sent to the addition input terminal Ia of the counter 112 via an AND circuit 129 and an OR circuit 110.
Therefore, the count content of the counter 112 is “l
”, and the display circuit 115 displays this as “l” as the stage number.

Furthermore, at this time, the light receiving element 62 encounters the first stage scale 51a of the recording sheet 46, and the first stage signal rlJ, which is the output signal, is generated.
is generated and applied to the reset input terminal R of the flip-flop circuit 99 via the inverter circuit 101 to put the flip-flop circuit 99 into a reset state.

When the carriage is moved in the direction of arrow A, the rotating disk 75 rotates in the direction of arrow B, so that light is sequentially distributed to the other end of the light guide member 58 through the light distribution hole 75a. Thus, at one end of the light guide member 58, light is emitted sequentially from the one located on the right side to the one located on the left side, and the rlJ stage of the recording sheet 46 is optically scanned in the direction of the arrow E.

On the other hand, when the carriage 7 is moved in the direction indicated by the arrow, the butts 4 of a large number of knitting needles 3 are relatively moved in the direction opposite to the arrow A and are introduced into the introduction passage 11 at the right end of the carriage 7. become.

When the knitting needle 3 reaches the needle selection position where the upper end of the butt 4 contacts the lower surface of the guide plate 22 of the electromagnet 16 at the right end and the side edge contacts the side edge of the guide strip 20, , when a square in the rlJ row of the recording sheet 46 corresponding to the knitting needle 3 is in a transparent state, light from one end of the light guide member 58 corresponding to that square passes through that square and exits from the other end. The light is now received by the light receiving element 65, and the light receiving element 65 generates a composition signal rlJ as an output signal.

Also, the time when the butt 4 of the knitting needle 3 reaches the needle selection position by the electromagnet 16 (the time when the light is distributed from the light distribution hole 75a of the rotating disk 75 to the other end of the light guide member 58 corresponding to the knitting needle 3)
, the light from the small through hole 75b of the rotary disk 75 is received by the light receiving element 74, and the light receiving element 74 generates the needle position signal rlJ as an output signal, which is input to the AND circuit 80.81 as an input signal. given as.

Therefore, when the light receiving element 65 generates the composition signal "1",
Since this signal is inverted by the inverter circuit 79 and applied to the AND circuits 80 and 81, the gate of the AND circuit 81 becomes open and generates an output signal "1", which is applied to the reset input terminal R of the flip-flop circuit 82. The flip-flop circuit 82 is put into a reset state.

As a result, the set output signal of the set output terminal Q of the flip-flop circuit 82 is "0" and I is given as an input signal to the AND circuit 83.
The output signal of the AND circuit 83 becomes "0", and the electromagnet 1
Excitation coils 23 and 23 of Nos. 6 and 16 are not energized.

Therefore, as described above, the butt 4 of the knitting needle 3 located at the needle selection position of the electromagnet 16 at the right end of the carriage 7 is
The first guide path 1 of the carriage 7 without being attracted to the
4 to the first selected position, and the next time the carriage 7 turns around, it becomes ready to capture the first yarn and knit the ground line.

On the other hand, when the butt 4 of the knitting needle 3 reaches the needle selection position by the electromagnet 16 at the right end of the carriage 7, the square in the "1" row of the recording sheet 46 corresponding to the knitting needle 3 is filled with black ink, etc. If it is filled with a photosensitive substance, the light from one end of the light guide member 58 corresponding to the knitting needle 3 is blocked by the square and is not received by the light receiving element 65, and the light receiving element 65 receives the knitting signal. "0" is now generated, and this is passed through the inverter circuit 79 to the AND circuit 8.
0°81 as an input signal, the AND circuit 80 becomes gate open and generates an output signal "L" which is applied to the set input terminal S of the flip-flop circuit 82. The circuit 82 generates a set output signal "l" from the set output terminal Q, and supplies this as one input signal to the AND circuit 83.

Since the AND circuit 83 is given the signal "l" from the movable contact piece 84o of the pattern knitting switch 84 as the other input signal, the AND circuit 83 receives the output signal "1".
is generated and sent to the excitation coil 23 via the amplifier circuit 86 etc.
．． 23, and the excitation coil 23.23 is energized.

Therefore, as described above, the butt 4 of the knitting needle 3 located at the needle selection position of the electromagnet 16 at the right end of the carriage 7
The yarn is attracted by the yarn and guided to the second guide path 15 to reach the second selected position, and becomes ready to capture the second yarn and knit a pattern stitch the next time the carriage 7 moves back.

In this way, as the carriage 7 moves in the direction of the arrow, the rotating disk 75 moves every 32 of the many knitting needles 3.
rotates once in the direction of arrow B and repeatedly scans the "1" stage of the recording sheet 46 with light in the direction of arrow E via the light guide member 58, but when the carriage 7 is then reversed in the opposite direction of the arrow At the time of the inversion, the inversion detector 130 inverts the output signal from "0" to "1", and the constant width pulse generation circuit 136 generates a carriage inversion signal.

The carriage inversion signal from the constant width pulse generation circuit 136 is applied to the normal rotation input terminal Ia and the drive input terminal Ic of the pulse motor control circuit 104 as described above, and is also applied to the addition input terminal Ia of the counter 112. The pulse motor 37 advances the recording sheet 46 by one step so that one end of the light guide member 58 corresponds to the "2" step, and the count content of the counter 112 becomes "2" and this is displayed on the display circuit 115.

Then, when the carriage 7 is moved in the opposite direction of arrow A, the knitting needles 3 selected to the first or second selected position by the previous movement of the carriage 7 in the direction of arrow A knit the texture or pattern stitches. will be carried out.

Furthermore, when the carriage 7 is moved in the opposite direction of arrow A, the rotating disk 75 rotates in the opposite direction of arrow B, so that one end of the light guide member 58 can move the "2" stage of the recording sheet 46 as described above. On the other hand, the light is scanned in the opposite direction of arrow E, and in this case, the electromagnet 16 at the left end of the carriage 7 performs the same needle selection action as the electromagnet 16 at the right end.

As described above, by repeatedly moving the carriage 7 in the directions of arrow A and counter-arrow A, a line pattern corresponding to the picture pattern 54 of the recording sheet 46 is repeatedly formed on the knitted fabric, with 32 stitches as one unit. That will happen.

Thereafter, when the recording sheet 46 is forwardly fed to the final stage "24" and one end of the light guide member 58 corresponds to the "24" stage, the light receiving element 61 is moved to the final stage scale 5.
0b and generates the final stage signal "0" which is the output signal, this is given to the visual notification device 138 via the inverter circuit 137, and further to the single pulse generation circuit 139.
is now given to the auditory notification device 140 via
They will each make announcements.

Then, by moving the carriage 7 that time, the selection of the knitting needles 3 in response to the final stage signal is performed, and the carriage 7
When you turn around and move the pattern number "7",
The pattern knitting corresponding to the picture pattern 54 consisting of 1" to 24" rows is completed.

In the above case, at any time during the formation from the first stage to the last stage, that is, the notification device 138.140
When the contact pieces 103o-103□ of the repeat switch 103 are selectively closed until the final stage is notified, the output signal Ill of the inverter circuit 85 is transferred to the AND circuit 102 from the contact pieces 1032-103 of the repeat switch 103.
1030.

Then, as mentioned above, the recording sheet 46 is placed in the trailing stage.
When the light-receiving element 63 encounters the trailing stage scale 52a of the recording sheet 46 and generates an output signal "1" as a trailing stage signal, this is sent to the inverter circuit 10.
0 to the set input terminal S of the flip-flop circuit 99.
9 is in a set state (it is always in a reset state at the time when the first stage scale 51a encounters the light receiving element 62) and generates a set output signal rlJ from the set output terminal Q, which is input to the AND circuit 102 as an input signal. give as.

Therefore, the AND circuit 102 has its input signals rlJ, r
lJ and generates an output signal "l", which is applied to the input terminal Ib of the high-speed continuous pulse generation circuit 109, and the high-speed continuous pulse generation circuit 109 continuously outputs pulses at high speed from the output terminal O. occurs.

The output pulses from this high-speed continuous pulse generation circuit 109 are passed through an OR circuit 106 to a pulse motor control circuit 104.
is applied to the reversal input terminal Ib of the pulse motor control circuit 104 via an OR circuit 107.
c, the pulse motor control circuit 104 rotates the pulse motor 37 by a predetermined angle in the opposite direction of arrow C (reverse direction) every time a pulse is applied to the reverse input terminal Ib and the drive input terminal Ic, and records The sheet 46 is fed one step at a time in the direction opposite to the arrow (backwards).

Further, since the AND circuit 128 is supplied with the output signal "l" of the AND circuit 102, the AND circuit 128 passes the output pulse from the high-speed continuous pulse generation circuit 109 and outputs it to the OR circuits 111 and 113. The counter 112 outputs the counted contents "25" and "24" to the subtraction input terminal Ib of the counter 112 through the subtraction input terminal Ib of the counter 112.

-... changes.

Thereafter, when the recording sheet 46 is fed backward to the first stage "1", the light receiving element 62 encounters the first stage scale 51a and generates an output signal "l" which is the first stage signal, which causes the inverter circuit 101 to through the flip-flop circuit 99
Since the flip-flop circuit 99 is in a reset state, the set output signal at its set output terminal Q becomes "0", and the reverse input terminal Ib and drive input terminal of the pulse motor control circuit 104 are input to the reset input terminal R of the pulse motor control circuit 104. I
c and the subtraction input terminal Ib of the counter 112 are no longer supplied with pulses, so the backward feeding of the recording sheet 46 is stopped, and the count contents of the counter 112 at this time are I
ll, and this is displayed on the display circuit 115.

Note that the time required to feed the recording sheet 46 backward from the 25th stage to the 11th stage depends on the pulse generation speed from the high-speed continuous pulse generation circuit 109, and is set to an extremely short time.

As a result, if the operator continues to move the carriage 7 in the directions of arrow A and counter-arrow A, the operator can again knit the pattern corresponding to the picture pattern 54 in the section with pattern number "7" on the recording sheet 46.

By the way, when the forward push button switch 116 is manually closed, one output pulse is generated from the single pulse generation circuit 120 at the time of closing, and this output pulse is transmitted through the OR circuits 110 and 105 and through the OR circuit 107. Since the signal is applied to the normal rotation input terminal Ia and the drive input terminal Ic of the pulse motor control circuit 104, the recording sheet 46 is fed forward by one stage.

Then, the pulse from the OR circuit 110 is sent to the counter 112.
Since it is also applied to the addition input terminal Ia of the counter 1,
The count content of 12 also increases by rlJ.

Further, when the forward button switch 117 is closed, the low-speed continuous pulse generating circuit 121 continuously generates output pulses at a low speed only while the forward button switch 117 is closed, and this is used to control the pulse motor in the same manner as described above. Normal rotation input terminal Ia of circuit 104
Since the recording sheet 46 is fed to the drive input terminal Ic and the addition input terminal Ia of the counter 112, the recording sheet 46 is continuously fed forward at a low speed while the forward push button switch 117 is closed. increases the count contents sequentially.

Furthermore, when the reverse push button switch 122 is closed,
When it is closed, one output pulse is generated from the single pulse generation circuit 126, and this is transmitted to the reverse rotation input terminal Ib of the pulse motor control circuit 104 via the OR circuits 111 and 106 and the OR circuit 107, and to the drive input terminal Ic. Therefore, the recording sheet 46 is fed backward by one step.

Then, the output pulse from the single pulse generation circuit 126 is sent to the counter 1 through the OR circuit 111 and the OR circuit 113.
12 subtraction input terminal Ib, the counter 112 decrements the count by "l".

Furthermore, when the reverse push button switch 123 is closed, the low-speed continuous pulse generation circuit 127 is activated only while it is closed.
generates output pulses continuously at a low speed, which is applied to the reverse rotation input terminal I of the pulse motor control circuit 104 in the same manner as described above.
b, drive input terminal Ic, and subtraction input terminal Ib of the counter 112, the recording sheet 46 is continuously fed backward at a low speed while the backward push button switch 123 is closed, and in response, the counter 112 is Decrease the count contents sequentially.

As described above, even if the carriage 7 is not operated, by operating the forward push button switch 116 or the backward push button switch 122 once or several times to close the recording sheet 46, the recording sheet 46 will be moved one step according to the number of operations. Alternatively, the recording sheet 4 can be moved forward or backward several steps, and by closing the forward push button switch 117 or the backward push button switch 123.
6 can be continuously moved forward or backward by a desired number of stages.

Therefore, even if you make a mistake in knitting a pattern during knitting and the knitted fabric is unraveled, the record sheet 46
can be returned as appropriate.

Note that it is convenient if the counters 94, 112, etc. are constructed of so-called non-volatile elements that have the ability to memorize the counted contents even when the normal power is turned off.

Furthermore, when selecting a pattern number smaller than the pattern number that is the count stored in the counter 94 using the pattern number selection switch 92, the following operation is performed.

For example, if the count content of the counter 94 is "8" when you try to select pattern number "7" with the pattern number selection switch 92, that is, the pattern number selection switch 92 is set to the "8" position. When the reverse pushbutton switch 122 or 123 is pressed and closed, the recording sheet 46 is moved backward as appropriate, and the light guide member 58 is
At one end of the eighth section of the recording sheet 46 (
The stages in which the contents of the counter 112 become "0" and the respective notification devices 138 and 140 operate are made to correspond.

After that, the movable contact piece 92o of the model number selection switch 92
by contacting the fixed contact piece corresponding to pattern number "7" and then operating the start button, the numerical content "
7'' as an output signal, the comparator circuit 93 generates an output signal ``1'' from the negative output terminal ob because the difference between the numerical value ``7'' at the input terminal Ia and the count content ``8'' at the input terminal Ib is negative. '' is applied to the input terminal Ia of the high-speed continuous pulse generation circuit 109.

As a result, the high-speed continuous pulse generation circuit 109 generates output pulses continuously at high speed from the output terminal O and applies them to the reverse rotation input terminal Ib and the drive input terminal Ic of the pulse motor control circuit 104, and the recording sheet 46 is sent backward.

After that, the light receiving element 60 detects the pattern number "7" on the recording sheet 46.
When the count scale 49a corresponding to " is encountered and an output signal "0" is generated as a count signal, this is passed through the inverter circuit 97 to the input terminal of the single pulse generation circuit 98.
given to.

Therefore, the single pulse generation circuit 98 generates one output pulse from the output terminal O and provides it as an input signal to the AND circuit 96.
Since the output signal "l" from the negative output terminal ob of the counter 94 is given as an input signal, the pulse is given to the subtraction input terminal Ib of the counter 94, and the count content of the counter 94 becomes "7".

As a result, the output signal "l" at the negative output terminal ob of the comparator circuit 93 disappears, and backward feeding of the recording sheet 46 is stopped.

Therefore, one end of the light guide member 58 corresponds to the "0" stage which is the prefix stage of the pattern number "7" on the recording sheet 46.

In addition, the counter 94 is set by the pattern number selection switch 92.
When selecting the dog pattern number from the pattern number that is the counting content stored in the , there is no need to perform the operation to return to the prefix "O" of the section of the pattern number that is set at that time. , immediately select the pattern number selection switch 92 and then operate the start button.

As a result, the recording sheet 46 moves forward and stops so that one end of the light guide member 58 corresponds to the "0" stage, which is the prefix stage of the newly selected pattern number.

However, at this time, the contents of the counter 112 remain as they were for the previous pattern number, so before starting to knit a line pattern with a new pattern number, be sure to The contents of the counter 112 are reset to "0" by once releasing and then short-circuiting.

Also, when changing the pattern number selection switch 92 to the position of a small pattern number, first set it to the position of a large pattern number, advance and stop the recording sheet 46, and then select the desired small pattern number. Alternatively, the recording sheet 46 may be reset to the position shown in FIG.

In any case, the pattern number selection switch 9
2 to a different pattern number position, press the contact pieces 103o, 103.2 of the repeat switch 103. Short-circuit between them to disable repeat operation.

Further, in the base body 64 of this example, a transparent portion is formed only in a portion corresponding to the pattern number display portion 48 and the row number display portion 53 of the recording sheet 46 at the same row position where one end portion of the light guide member 58 is arranged. Furthermore, the design is such that discrepancies between the contents of the counter 94 and the pattern number on the recording sheet 46 can be easily discovered by allowing appropriate observation from above through a window (not shown) in the auxiliary machine frame 24. It is.

According to this embodiment, the line pattern 54 is recorded and displayed on the translucent recording sheet 46 using a luminescent material such as black ink, and the recording sheet 46 is placed close to the recording sheet 46 at one end. The presence or absence of the pattern 54 is detected by the light-receiving element 65 as a difference in light transmittance, for example, the presence or absence of transmitted light, by scanning the light with the light-guiding member 58 in which the pattern 54 is arranged. Signal "l", "0"
generates an electric signal, and in response to the electric signal, causes a positional difference between a first selection position and a second selection position on a large number of knitting needles 3 using an electromagnet 16 provided on the carriage 7,
This allows the knitting of the ground stitch and the pattern stitches, and therefore, unlike the conventional method in which many brush members are brought into sliding contact with the recording medium to read the knitting signals, contact failures occur. , there are no problems such as wear, and processing such as reading formation signals can be performed reliably.
It can have a long life.

Moreover, according to this embodiment, the pattern number selection switch 9
2, the line pattern with the desired pattern number can be selected from among the many line patterns recorded on the recording sheet 46.
In addition, by simply operating the repeat switch 103, the same pattern number can be automatically repeated and selected, and by selectively closing the forward push button switches 116 and 117 and the backward push button switches 122 and 123, recording can be performed. There is an advantage that the sheet 46 can be fed forward or backward as desired, and correction of the feeding of the recording sheet 46 can be easily performed.

FIG. 11 shows a second embodiment of the present invention, in which the same parts as those in FIG. 3 of the above embodiment are given the same reference numerals, and the explanation thereof will be omitted, and only the different parts will be explained below.

That is, reference numeral 141 designates a light-blocking and internal reflection cover disposed above the recording sheet 46 in place of the base body 64 and light receiving element 65 in the above embodiment, and an embedded base body 59 is placed at the bottom of the cover with the recording sheet 46 sandwiched therebetween. A long hole 141a is formed corresponding to the upper surface and having a width and length corresponding to, for example, a part of the recording sheet 46, and a lamp 142 such as a long tungsten lamp is disposed inside as a light source. There is.

Reference numeral 143 denotes a light receiving element (scanning member) consisting of a photovoltaic element disposed above the rotating disk 75 in place of the lamp 77 in the previous embodiment.

(electric signal generating means), which is formed in an annular shape corresponding to the rotation locus of the light distribution hole 75a of the rotating disk 75.

Reference numeral 144 denotes a light emitting diode as a light source disposed above the rotating disk 75 so as to correspond to the light receiving element 74 with the rotating disk 75 in between.

Therefore, when the lamp 142 is turned on, this lamp 14
Light beam from 2 and elongated hole 14 of light and internal reflection cover 141
1a and any one stage of the recording sheet 46, it is simultaneously applied to each one end of the light guide member 58 in the embedded base 59.

That is, the light guide member 58 receives the transmitted light from the recording sheet 46 at each end and emits light from the other end, so that it rotates in a rotating circle according to the pulley 26 as the carriage 7 (see the above embodiment) moves. When the plate 75 is rotated in the directions of arrow B and counter-arrow B, the light distribution holes 75a of the rotating disc 75 are rotated to each other end of the light guide member 58 in a predetermined order, and the light receiving element 143 is rotated. The light from the other end of the light guide member 58 facing the light distribution hole 75a is received, and as a result, the light guide member 58 optically scans the recording sheet 46 in the directions of the arrow E and the direction opposite to the arrow E.

As a result, if the light receiving element 143 is used in FIG. 10 instead of the light receiving element 65 of the above embodiment, the same effects as in the above embodiment can be obtained.

FIGS. 12 to 16 show a third embodiment of the present invention,

Next, the operation of the third embodiment having the above configuration will be explained with reference to the waveform diagram shown in FIG.

First, when knitting is performed using the recording sheet 151 for large patterns, the contact piece 185o of the manual changeover switch 185 is
-1850 is selectively closed and the lamp 156 is energized and turned on.

As a result, the light from the lamp 156 passes through the long hole 155 of the guide plate 24a to the pattern display section 152 of the recording card 151.
Therefore, each end of the light guide member 161 corresponding to an arbitrary row of the pattern display section 152 receives the light transmitted through that row, and the picture pattern is emitted from each other end of the light guide member 161. It emits light depending on the presence or absence of 153.

When the carriage 7 is attached to, for example, the right end of the needle bed 2 and moved to the left in the direction of arrow A (hereinafter simply referred to as the entry direction), the photodetectors 174 and 175 are moved in the same direction. It moves in the A direction and comes to correspond alternately to the non-reflective part 165 and the reflective part 166 of the scale body 164, and when it corresponds to the non-reflective part 165, it produces an output signal "0" and when it corresponds to the reflective part 166. At times, the output signal "1" will be produced, so that the photodetectors 174 and 175 will produce output pulses P1 and P2, respectively, as output signals.

This also applies when the carriage 7 is moved in the opposite direction of arrow A, that is, to the right (hereinafter simply referred to as the A' direction).

The output pulse P1 of this photodetector 174 is given as an input signal to the differentiating circuit 187 via the inverter circuit 186, so that when the differentiating circuit 187 is in the A direction, the other end 161a of every other light guide member 161 is An output pulse P is output as an output signal corresponding to every other knitting needle 3a of the knitting needle 3.
3a and in the A' direction, an output pulse P is generated as an output signal corresponding to the remaining other end 161b of the light guiding member 161, and thus every other remaining knitting needle 3b of the knitting needle 3.
3b, and since the output pulse P1 of the photodetector 174 is directly given as an input signal to the differentiating circuit 192, the differentiating circuit 192 corresponds to the other end 161b of the light guide member 161 when in the A direction. Then, an output pulse P4a is generated as an output signal, and an output pulse P4b is generated as an output signal corresponding to the other end 161a of the light guide member 161 when the light guide member 161 is in the A' direction.

Then, the output pulse P3a or P3 of the differentiating circuit 187
b is given as one input signal of AND circuits 188 and 190, and output pulse P4a or P of differential circuit 192
4. is given as an input signal to one of the AND circuits 189 and 191, and the output pulse P of the photodetector 175
2 is given as the other input signal of the AND circuits 188 to 191, so when the carriage 7 is in the A direction, output pulses are generated alternately from the AND circuits 188 and 189 for the left row, and the OR circuit 193 outputs pulses from the light guide member 161. Output pulses corresponding to the other end, that is, the knitting needle 3, are generated sequentially as a needle position signal, and when the carriage 7 is in the A' direction, output pulses are generated alternately from the AND circuits 190 and 191 for the right row, and the OR circuit 194 From then on, an output pulse is generated as a needle position signal.

From the above, when the carriage 7 is attached to the right end of the needle bed 2 and moved in the A direction as described above, a needle position signal is generated from the left OR circuit 193 and the needle position signal is Storage elements 178□ to 17821 of shift register 178
In other words, the needle position signal in the form of 10 pulses is applied to the input terminal I of the counter 196. Then, when the carriage 7 is moved in the direction A by an amount corresponding to ten knitting needles 3, the counter 196 generates an output pulse and applies it to the set input terminal S of the flip-flop circuit 198.

Therefore, the flip-flop circuit 198 enters the set state and generates a set output signal "1" from the set output terminal Q, and the differentiating circuit 199 which takes this as an input signal generates an output pulse and sends it to the OR circuit 201. is applied to the input terminal of the constant width pulse generation circuit 202 via the constant width pulse generation circuit 202.

As a result, the constant width pulse generation circuit 202 outputs the output terminal 0.
A constant width pulse is generated and applied to the base of the transistor 203, and the transistor 203 is turned on for a short period of time, and the excitation coil 159 is controlled to be energized once, and the recording card is moved by the step feeding mechanism 160. 151
is advanced by one step in the direction of arrow G.

Thereafter, the carriage 7 is further moved in the direction A, and the light receiving element 173 corresponds to the other end of the rightmost light guide member (hereinafter referred to as light guide member 161c numbered 100 for convenience) among the light guide members 161. Corresponding to the rightmost knitting needle of the knitting needles 3 (hereinafter referred to as knitting needle 3c numbered 100 for convenience) (see Fig. 14), at this time, the light guide member 1 of number ioo
If the picture pattern 153 exists in one row of the recording card 151 to which one end of the card 61c corresponds and the other end does not emit light, the light receiving element 173 generates an output signal "0" as a composition signal. This is now applied to the information input terminal 1 of the shift register 178 via the OR circuit 176 and the impark circuit 177, and the first stage storage element 178 of the shift register 178 becomes Ill, so that the storage element 1
780,1782. ...The content of 178□1 is "l",
"0", . . . "0".

Also, at this time, the electromagnet 16 at the right end of the carriage 7 which performs the needle selection function is located to the right of the number ioo knitting needle 3c by a distance corresponding to 20 knitting needles 3.

Thereafter, when the carriage 7 moves in the A direction, the OR circuit 195 generates a needle position signal, and the content "l" of the first stage storage element 1781 of the shift register 178 is sequentially transferred to the next stage storage elements 1782 to 1782. When 20 needle position signals are generated after the light receiving element 173 generates the knitting signal as described above corresponding to the other end of the light guide member 161c numbered 100, the shift register 178
The output signal of the output terminal O becomes "l", and at this time, the light receiving element 173 corresponds to the light guide member 161d numbered 80, which is shifted to the left by 20 lines from the light guide member 161c numbered 100 among the light guide members 161. At the same time, the number 100 knitting needle 3c is located at the needle selection position of the electromagnet 16 at the right end of the carriage 7.

Then, the output signal "l" of the shift register 178 is given to the base of the transistor 180 via the amplifier circuit 179, so the transistor 180 is turned on and the excitation coils 23 and 23 are energized. The knitting needle 3c is selected to the second selection position.

Thereafter, in the same manner, corresponding knitting needles 3 are sequentially selected to the first or second selection position in accordance with the knitting signal from the light receiving element 173.

On the other hand, when the carriage 7 is reversely moved from the A direction to the N direction, a needle position signal is now generated from the right OR circuit 194 via the right AND circuits 190 and 191. The data is supplied to each storage element 178 to 17821 of the shift register 178 via the OR circuit 195 and to the counter 19 for the right row.
7, so the counter 197 is connected to the input terminal I
When 10 needle position signals are applied, one output pulse is generated from the output terminal O and applied to the reset input terminal R of the flip-flop circuit 198.
The flip-flop circuit 198 is inverted to the reset state and generates a reset output signal "1" from the reset output terminal Q, which is differentiated by the differentiating circuit 200 and passed through the OR circuit 201 to the input terminal 1 of the constant width pulse generating circuit 202. Therefore, as described above, the excitation coil 159 is controlled to be energized once more, and the recording card 151 is
is further advanced by one step in the direction of arrow G.

In addition, the carriage 7 moves from left to right or from right to left with knitting needles 3.
When the pulse is inverted by 0, the pulse output from the counters 196 and 197 causes the flip-flop circuit 198 to be activated.
is set or reset, the other counters 196 and 197 are mutually reset, so the counting operation of the reset counters 196 and 197 is immediately stopped and the next input pulse is reset to "1" or "1" again. 2", and even if the carriage 1 is turned back and turned over at any position on the needle bed 2, the knitting needles 3
After moving by O length, the excitation coil 159 of the electromagnetic ratchet device starts operating.

Now, when knitting is performed using the recording card 145 for small patterns, the contact piece 185o of the manual changeover switch 185 is
-185□ is selectively closed, and the lamp 142 is energized and turned on.

As a result, each one end of the light guiding member 58 is connected to the recording card 1.
The transmitted light corresponding to the presence or absence of the picture pattern 147 in the corresponding arbitrary row of the pattern display section 146 of 45 is received and emitted from the other end.
The light-receiving element 143 sequentially detects the rotation and generates a compiling signal.

The composition signal from the light receiving element 143 is sent to the information input terminal 1 of the shift register 178 via an OR circuit 176 and an inverter circuit 177 instead of the light receiving element 173.
Therefore, subsequent selection of knitting needles 3 is performed in the same manner as described above.

In each of the above embodiments, the light transmitted through the recording sheet 46 or the recording cards 145, 151 is transmitted to the light receiving element 65 or 14.
