Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for creating a control card displaying pixel signals for selecting knitting needles for a hand knitting machine.

Conventionally, in hand-knitting machines in which knitting patterns can be formed by reading signals on cards, for example, rectangular pixel areas are formed on a light-transmissive sheet by a large number of square lines. A control card is formed by forming a large number of pixels, and applying pixel signals by painting the desired pixel area with light-shielding black, and optical scanning is performed by a slit that moves on such a control card in conjunction with a carriage. The above pixel signals are read by an optical sensor, and the needle selection member is controlled by the read signals to select the desired needles, thereby creating a pattern corresponding to the knitting pattern displayed by the pixel signals on the control card. A method of organizing was considered. This method has the disadvantage that it requires a great deal of effort to create the control card. That is, first of all, the operator has to guide the pattern (knitting pattern) to be displayed on the control card, which is a hassle, and secondly, the relationship between each pixel area and each knitting needle is complicated. Therefore, when displaying a knitting pattern as a pixel signal on a control card, there is no need to display the pixel signal in consideration of the relative positional relationship between the knitting pattern and the pixel area. be.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to provide a recording medium in which a knitting pattern is recorded and displayed based on the difference in light transmittance or light reflectance;
A projection device that optically projects the knitting pattern on the recording medium, and a pixel area corresponding to the knitting needles installed in the projection position of the knitting pattern projected by the projection device and arranged in a row on the needle bed. control card,
The control card is configured to include a writing instrument for appropriately writing pixel signals for knitting needle selection in each pixel area of the control card, so that the knitting pattern on the recording medium is projected onto the control card. The relative positional relationship between each pixel area and the projected knitting pattern becomes clear, and pixel signals according to the projected knitting pattern can be written using the specified relative positional relationship as a guide, making it easier to write in the data. Not only does this not require as much attentiveness, it also makes it possible to prepare a large number of recording media displaying different desired knitting patterns in advance and use them arbitrarily, making the work of creating control cards extremely easy. The present invention provides a control card creation device for a knitting needle control device of a hand knitting machine.

Each embodiment of the present invention will be described below. 1 to 4 are for explaining the first embodiment, and FIG. 1 shows a control card production device. That is, in FIG. 1, reference numeral 1 denotes a housing, in which a guard receiving frame 3 is removably installed in a raised recess 2 formed approximately at the center of the bottom wall, and an opening 4 is formed in the upper surface of the raised recess 2. A plate-shaped recording medium 5 is removably installed on the upper surface of the guard receiving frame 3 through this opening 4. The knitting pattern 6 is recorded and displayed on this recording medium 5 based on the difference in light transmittance or light reflectance. In this embodiment, the case where the knitting pattern 6 is recorded and displayed based on the difference in light reflectance is taken as an example. . A light shielding frame 8 is disposed within the housing 1 and tilts downward from the upper end opening 7 toward the upper part of the opening 4 of the raised recess 2. A lens 10 is attached via a lens support frame 9 so that it can be replaced with another lens. Reference numerals 11 and 12 indicate illumination lamps arranged to illuminate the recording medium 5 installed in the guard receiving frame 3. Reference numeral 13 denotes a projection receiving plate which also serves as a control card mounting plate, and is made of a transparent plastic plate with a roughened surface or so-called frosted glass, and is inserted into the upper end opening 7 of the housing 1 by fitting means or the like. It is placed horizontally and is removable. Reference numeral 14 denotes a control card made of a transparent material in the form of a sheet, on which a large number of square-shaped pixel areas 16 are clearly indicated by vertical and horizontal square lines 15a and 15b, and in the left and right margins, a stage feed is provided. Holes 17 are formed with a predetermined pitch in the vertical direction. As will be understood from the embodiments described later, each of the pixel regions 16 corresponds to each knitting needle in its horizontal arrangement. Reference numeral 18 denotes a card holding frame, which stops the movement of the control card 14 by pressing the control card 14 installed on the projection receiving plate 13 through its peripheral edge. The control card 14 is positioned by passing a positioning protrusion 19 protruding from the top surface of the casing 1 through a desired feed hole 17 of the control card 14 and into a through hole 20 of the card holding frame 18. . In addition, when the projection receiving plate 13 is made of a transparent plate, the control card 14 is made of a semi-transparent material with a roughened surface. According to the above configuration, the illumination lamps 11 and 12
When the upper surface of the recording medium 5 is irradiated with light, the knitted pattern 6 on the recording medium 5 is illuminated by the lens 10 due to the reflected light.
The knitting pattern 6 is projected onto the projection receiving plate 13 (corresponding to the lower surface of the control card made of semi-transparent material if the projection plate is a transparent plate) through the control card 14, and the knitting pattern 6 appears as a projected image on the control card 14. Then, the operator writes the pixel signal 22 on the upper surface of the control card 14 using the writing instrument 21, which is a black pen, using the projected image as a guide. The method for writing this pixel signal 22 is to fill the pixel areas 16 in black with a writing instrument 21 so that the outline of the projected image area is expressed by a large number of pixel areas 16, as shown in FIG. It is carried out with FIG. 3 shows an example in which pixel signals 22 are entered so that only the desired outline in the projected image of the knitting pattern 6 is expressed in the pixel area 16, but as shown in FIG. The pixel signal 22 may also be written by a method such as filling in the pixel signal 16 as well. In addition, the projected image of the knitting pattern 6 is projected onto the lens 10.
The pixel signals 22 corresponding to knitting patterns of various sizes may be written by exchanging the lenses or by using a zoom lens as the lens 10 to enlarge or reduce the size. According to the device for creating the control card 14, a large number of recording media 5 on which various different knitting patterns 6 are recorded can be prepared in advance, and any of these can be arbitrarily selected and used for creating the control card 14. , there is no need to worry about coming up with a knitting pattern one by one.
Further, the knitting pattern 6 on the recording medium 5 is projected onto the control card 14, and the relative positional relationship between the pixel area 16 of the control card 14 and the projected image becomes clear, and the clearly indicated relative position Since the pixel signal 22 can be written in accordance with the projected image using the relationship as a guide,
There is no need to be attentive, such as having to work hard to select the pixel area 16 where the pixel signal 22 is to be written, and therefore the work of writing the pixel signal 22 is extremely easy. Also,
In addition to filling in the projected image exactly as it is,
Workers are free to make corrections according to their preference.
More accurate pixel signals can be written. In the above embodiment, the pixel area 16 is used to write the pixel signal 22.
Although a method of filling in the entire pixel signal 22 is used, the present invention is not limited to this method, and may be any writing method that allows a signal reading means, which will be understood later, to read the pixel signal 22.

Further, the tips of the other stems 72a and 74a are similarly slidably protruded from the rear end wall of the button unit frame 77 in a two-layered state. Reference numeral 78 denotes an operator which is attached to the button unit frame 77 by an appropriate means so as to be movable back and forth and which is always elastically biased forward.

Only when any of the buttons 1 and 72, the buttons 73 and 74 for slip stitch knitting, and the button 76 for color scheme knitting is set to the active position, the sliders 85 and 86 come into contact with the sliding conductive bands 87 and 88, and the above-mentioned The excitation coils 66 of the left and right row needle selection members 59A, 59B can be energized only during pattern knitting, thereby making it possible to prevent unnecessary sliding during normal plain knitting. That is, for example, when the color scheme button 76 is slid from the two-dot chain line position to the solid line position in FIG.
The tip of the stem 76a protrudes as shown in the figure and presses the abutting pin 83, so the levers 79, 80

Now, as shown in FIG. 10, the scanning drum 43 has a scanning pattern in which a slit that goes around twice in the right-hand thread direction from the same position and a slit that goes around twice in the left-hand thread direction intersect in the middle. In addition to forming a window 90, for example, 16 synchronization through-hole windows 91 are formed on the outer periphery of the right end. Here, each element forming the scanning window 90 will be referred to as scanning window sections 90a to 90h as shown in FIG. The rotation body 49 is transmitted to a pinion 95 fixed to the shaft 46 for rotating the scanning drum 43 via a gear portion 92 and intermediate gears 93 and 94 provided to rotate integrally with the rotation body 49. It's becoming like that. The rotating body 49 rotates once when the carriage 29 moves by 64 knitting needles 25, and the scanning drum 43 rotates four times for each rotation. 25 corresponds to the movement amount of 16 lines, and as will be understood later, each scanning window portion 90a to 90h
will respectively share the scanning of eight pixel areas 16 in the horizontal direction. Inside the scanning drum 43, there are scanning windows 90a, 90e, 90b, 90f, respectively.
, 90c, 90g, and 90d, 90h, the slits 44,
Pixel signal light receiving elements 96a to 96d made of photoelectric conversion elements are arranged facing 45, and a synchronization light receiving element 97 is arranged on the same line as these pixel signal light receiving elements 96a to 96d, and facing this light receiving element 97. The card receiving plate portion 30 and the card holding plate 31 are provided with through holes 98, 98 that receive light from the light source lamp 42, and the synchronization through hole window 91 scans over the synchronization light receiving element 97. Eggplant. 99 is a gate control disc mounted on the rotating body 49 so as to rotate together with the rotary body 49;
As can be understood from FIG. 10, gate control slits 99 are sequentially placed in each divided area divided into eight equal parts in the circumferential direction.
A to 99g are formed, and the last divided area is made into a non-slit structure (this is referred to as a non-slit area 99h). In this case, each gate control slit 99a to 99g is formed on a circumference with a different radius. Further, a large number of transparent windows 100 for pattern creation (indicated by diagonal lines) are formed intermittently around a different circumference from the gate control slits 99a to 99g of the gate control disk 99. The mutual spacing between the transparent windows 100 for pattern creation is as follows:
This corresponds to the time interval in which the needle selection possible positions of the left or right needle selection members 59A, 59B are located on every other knitting needle 25. Although detailed illustrations are omitted,
For example, FIG. 6 shows gate control light receiving elements 101a to 101g and pattern creation light receiving elements 100a, which are photoelectric conversion elements that receive light from a light source (not shown) that has passed through the gate control slits 99a to 99g and the pattern creation transparent window 100. They are fixedly arranged as shown in the figure. Next, the electrical components will be explained together with the effects of the mechanical components. First, as is clear from FIG. 10, the scanning drum 43

f), 90c (or 90g) and 90d (or 90h) are four unit pixel area sections PAa, PAb, PAc, with eight pixel areas 16 as one unit.
The relationship is such that each PAd is scanned in a light-transmissive manner. FIG. 11 shows a rotationally developed view of the scanning drum 43 rotated four times as the gate control disc 99 rotates once together with the rotating body 49, and a fully rotated view of the gate control disc 152 rotated once. are shown in a temporally corresponding relationship. In FIG. 11, an arrow 102 indicates the scanning drum 43.
and the direction of rotation of the gate control disk 99, and RT1, RT2, RT3, and RT4 indicate the development view areas for the first, second, third, and fourth rotations of the scanning drum 43, respectively. ing. Now, move the carriage 29 in the left direction (indicated by arrow 68 in Fig. 8).
Assuming that the carriage 29 is actually moved to the left (since the figure shows the carriage 29 seen through from above), the scanning drum 43 is rotated in the direction of the arrow 102 in FIG. Each of the scanning windows 90a to 90h scans each unit pixel area section PAa, PAb, PAc, PAd on the control card 14 through the slit 4 in a direction depending on the respective inclination direction.
4 and 45, and as a result, a digital signal corresponding to the presence or absence of the pixel signal 22 in each pixel area 16 is output from each pixel signal light receiving element 96a to 96b, and this is waveform shaped (not shown). The circuits and lines L1a to L1d and the respective lines L2a and L2 via the first switching circuit 103

On the other hand, due to the leftward movement of the carriage 29 as described above, the gate control disc 49 is also rotated in the direction of the arrow 102 in FIG. Each time light from a light source (not shown) is received through the control slits 99a to 99g, a (1) signal that becomes a positive potential is output, and these signals are transmitted to each corresponding line L via a waveform shaping circuit (not shown).
3a to L3g as gate timing signals P2a to P2g, respectively. By connecting each input terminal of the NOR circuit 104 to each line L3a to L3g and connecting the line L3h to the output terminal of the NOR circuit 104, this line L3h receives all the gate timing signals P2a to P2a. When P2g becomes zero potential, that is, the gate control light receiving elements 101a to 101g
Another gate timing signal P2 that becomes a positive potential when the non-slit region 99h is located above.
h is now output. Therefore, the gate timing signals P2a to P2h are generated in sequence in synchronization with 1/2 rotation of the scanning drum 43, respectively.
The above operation is repeated after the fifth rotation of the scanning drum 43. Each of the lines L3a to L3

Next, the operation of the second embodiment will be explained.
Now, if the carriage 29 is moved from the right end to the left as shown by the arrow 68 in FIG.

The presence or absence of the pixel signal 22 inside is read, and a digital electric signal corresponding to the presence or absence is outputted in parallel to lines L1a to L1d as an output card signal. In this case, among the output card signals output, the output pixel signal P1a corresponding to the pixel signal 22 is a (0) signal at an electrically low level (for example, zero potential). As the scanning drum 43 rotates as described above, the synchronization light receiving element 97 generates a needle pulse P3, which is the (1) signal, by the light passing through each synchronization through-hole window 91 of the scanning drum 43. As can be understood from FIG.
45 is located in the center of the pixel area 16, it is determined to face the synchronization light receiving element 97, and the straight lines 125a, 125
As shown in b, at this time, the guide strip 63 of the needle selection member has just reached the needle selection start position, and the left and right needle selection members 59

is the maximum pattern unit, that is, in this embodiment, twice the horizontal number of pixel areas 16 formed on the control card 14, and is the same as 64 knitting needles 25 when the gate control disk 99 rotates once. determined by the interval. Now, prior to the above-described operation of the carriage 29, the interlocking switch 118 is set to the state shown by the solid line in FIGS. 11 and 12, and the movable contact of the first pattern selection switch 106 is 1
07 is selected to be in contact with the fixed contact piece 107a, and the line L7 is always in the (0) signal state. In this state, only the fixed contact piece 107a has a positive potential, that is, the (1) signal , the AND circuit 105e ₃ , 105
f ₃ , 105g ₁ , 105c ₁ , 105h ₁ , and 105d ₁ are in a half-open state. In such a state, the output pixel signal P1a, which is a (0) signal, which is output in parallel in time to the lines L1a to L1d as the carriage 29 moves leftward as described above, is inverted in level by the inverters 117a to 117d. Each final stage AND circuit 1 via L2a to L2d
14a to 114d. On the other hand, during the RT1 period of the first rotation of the scanning drum 43, the gate timing signal P2 is applied to the line L3a during the first half rotation.
In the second half rotation, the gate timing signal P2d is outputted to the line L3b in sequence, and similarly, a half-rotation cycle is output to the husband lines L3c to L3h during the second rotation RT2, third rotation RT3, and fourth rotation RT4. The gate timing signals P2c to P2h are output in this order. Of these, the gate timing signal P2 generated at the first rotation RT1
a and P2b are sequentially supplied to OR circuits 113a and 113b, and gate timing signals P2c and P2d generated at the third rotation RT2 are sequentially supplied to AND circuits 105c ₁ and 105d ₁ in a half-open state, and the respective (1) signals The OR circuits 113c and 113d output
supply in order. Therefore, the final stage AND circuit 114
a, 114b, 114c, and 114d perform the opening operation in the above order every half rotation during the period in which the scanning drum 43 makes two rotations. The third rotation of the scanning drum 43,
Similarly to the above, during a total of two rotations in RT3 and fourth rotation RT4, the final stage AND circuits 114a and 11
4b, 114c, and 114d sequentially open each half rotation. On the other hand, as understood from the connection configuration in FIG. 11, the final stage AND circuit 114a controls the passage of the output pixel signal P1a by photoelectric scanning of the scanning windows 90a and 90e, and similarly, the final stage AND circuit 114b and 114c and 114d are scanning windows 90b, 90f and 90c, 90g, respectively.
In addition, since the relationship is such that the passage of the output pixel signal P1a by the photoelectric scanning of 90d and 90h is controlled, the final stage AND circuit is 114
a, 114b, 114c, 114d, 114a,
Due to the relationship in which the windows 114b, 114c, and 114d are opened in this order, the output pixel signal P1a that is output in parallel in time to the lines L2a to L2d is transmitted to the scanning windows 90a, 90f, 90c, and 90.
Only the signals generated by the scanning by h are converted into temporally serial signals by the final stage AND circuits 114a to 114d, and are converted into temporally serial signals in each unit pixel area section.
PAa, PAb, PAc, PAd, PAa, PAb, PAc,
OR circuit 11 is connected to line L6 in the order of PAd.

Final stage AND circuit 114a at each selected position of f
The opening operations of 114d to 114d enable photoelectric scanning of the scanning windows 90a to 90h, and the effective photoelectric scanning of unit pixel area sections PAa to PAd (here, "valid" means that the output pixel signal P1a is L
6) is shown in FIG. 14. Furthermore, Figure 14 shows the carriage 2.
9 illustrates the operation of the scanning drum 43 up to four rotations in the leftward movement of No. 9. Therefore, the operations after the fifth rotation are the same as those shown in FIG. 14. The output pixel signal P1a, which is the signal (1), supplied to the line L6 as described above is input to one of the other AND circuits 120 via the lines L8, L9, the changeover switch element 118e, the lines L12, L13, and L13a. terminal and the negative input terminal of the other AND circuit 121 at the same time, and each pixel region 16
As a result, the needle pulse P3 generated in synchronization with the optical scanning to the center of
The AND circuit 120 is turned on as a result of the establishment of the AND condition with the needle pulse P3 and the flip-flop circuit 1.
22 to the set state. Then, an output (1) signal is generated from the set output terminal Q, which is transmitted to the left and right row needle selection members 59A, 59 via the amplifier 123.
The B excitation coils 66 are simultaneously excited to perform a needle selection operation for forming a knitting pattern. The reset of the flip-flop circuit 122 is performed in other pixel areas 1 in which the optical scanning position does not include the pixel signal 22.
6, the line L6 and line L13a become the (0) signal, and the needle pulse P3 is generated, and the output of the AND circuit 121 becomes the (1) signal, and the reset input terminal R of the flip-flop circuit 122 becomes the (1) signal. )
This is done by applying a signal.

As mentioned above, the fixed contact piece 107a of the first pattern selection switch 106 is selected and the knitting pattern 12 is selected based on the pixel signal 22 written on the control card 14.
6 is in the form shown in FIG. 15A, the knitting pattern 126 is simply knitted left and right repeatedly using 32 knitting needles 25 as one unit, as shown in FIG. 15B.

In addition, 127 is a knitted fabric. Also, a control card 14 used in this embodiment and the explanation of the embodiments to be described later.
It is assumed that 32 pixel regions 16 are formed in the horizontal direction.

When the fixed contact piece 107b is selected, as can be understood from FIG.
f, 90c, 90h, 90d, 90g, 90b,
Opto-electrical scanning by 90e is enabled and the order of the respective scanning operations is as described above with respect to leftward movement of carriage 29. At this time, if the control card 14 shown in FIG. 16A is used, two knitting patterns 126 are symmetrically and mutually arranged in an area of 64 knitting needles 25 as one unit, as shown in FIG. 16B. It is knitted in a connected state, creating a repeating pattern. This method of use has the advantage that only one half of the symmetrical knitting pattern needs to be written on the control card 14. On the other hand, as described above, the fixed contact piece 10
7b is selected and the control card 14 shown in FIG. 17A is used, as shown in FIG. 17B, the knitting pattern 126 has a symmetrical form with intervals left and right, that is, 32 knitting patterns. A knitting pattern 126 with knitting needles 25 as one unit is repeatedly knitted so as to be alternately reversed left and right.

When the fixed contact piece 107c is selected, as can be understood from FIG.
f, 90b, 90e, 90a, 90f, 90b,
Opto-electrical scanning by 90e is enabled and the order of the respective scanning operations is as described above with respect to leftward movement of carriage 29. At this time, as shown in FIG. 18A, if a knitting pattern 126 is written in only one half of the control card 14 in contact with the boundary in one half area of the control card 14, as shown in FIG. 18B, Two knitting patterns 12 are formed in an area with 32 knitting needles 25 as one unit.
6 are knitted in a symmetrical and interconnected state and are repeated to form a repeating pattern. Also the first
If a knitting pattern 126 is written approximately in the middle of one half area of the control card 14 as shown in FIG. The pattern 126 is repeatedly knitted so as to be alternately reversed left and right.

When the fixed contact piece 107d is selected, as can be understood from FIG. 14, the scanning windows 90a, 90f,
Only the photoelectric scanning by 90c and 90h is enabled in the first two revolutions of the four revolutions of the scanning drum 43, and in this case, in the latter two revolutions, all of the final stage AND circuits 114a to 114d open. At this time, the 17th
When the control card 14 shown in FIG. A is used, a knitting pattern 126 having 32 knitting needles 25 as one unit is knitted one by one as shown in FIG. 20. Furthermore, if the control card 14 shown in FIG. 17A is used with the fixed contact piece 107d selected as described above and the interlocking switch 118 set to the position shown by the dotted line, then the first half of the scanning drum 43 As shown in FIG. 21, the knitted fabric 1 is scanned by effective opto-electrical scanning by the rotating scanning windows 90a, 90f, 90c, and 90h.
A knitting pattern 126 similar to that shown in FIG. 20 is knitted in the first unit area of the scanning drum 4.
The knitted fabric of the next one unit area corresponding to the second half of the second rotation of 3 is knitted with yarn of the same color as the knitting pattern 126. This is because during the latter two rotations of the scanning drum 43, none of the final stage AND circuits 114a to 114d open, and the (1) signal is always output from the inverter 119 to the line L12.

When the fixed contact piece 107e is selected, the photoelectric scanning by the scanning windows 90a and 90f becomes effective, and the optical scanning action thereof is repeated every rotation of the scanning drum 43. In this case, if a control card 14 with a knitting pattern 126 written in the middle of one half area as shown in FIG. 22A is used, the control card 14 as shown in FIG. 2B is used.
A knitting pattern 126 having 16 knitting needles 25 as one unit is repeatedly knitted.

When the fixed contact piece 107f is selected, as shown in FIG. 14, the photoelectric scanning of the scanning windows 90a and 90c is simultaneously enabled during the first half rotation of the scanning drum 43, and the scanning windows 90a and 90c are enabled simultaneously during the next half rotation. The relationship is such that the photoelectric scans 90f and 90h are repeatedly enabled at the same time. Therefore, in this case, as shown in FIG. 23, one half area is filled with the graphic knitting pattern 1.
26a and write 1/1 in the other half area, for example.
When a knitting operation is performed using the control card 14 on which a dotted knitting pattern 126b such as 1/2, 2/2, etc. is written and the interlocking switch 118 is set to the solid line position, the graphic knitting pattern 126a on the control card 14 is and dotted pattern 1
26b is scanned at the same time, the filled graphic knitting pattern 126a becomes a double pattern formed against the background of the dotted knitting pattern 123b, as shown in FIG. 23B. On the other hand, when the interlocking switch 118 is set to the dotted line position and the knitting operation is performed, FIG.
As shown in FIG.
It is knitted in a pattern formed by 6b. That is, the output of the inverter 119 becomes the (1) signal only when the signal on line L9 becomes the (0) signal, and the line L6 becomes the (0) signal only at the final stage. Only when none of the AND circuits 114a to 114d open, the input pixel signal 2 in the graphic knitting pattern 126a is converted.
2 and the input pixel signal 22 in the dotted knitting pattern 126b are simultaneously output as (0) signals to the lines L1a to L1d, and due to this action, a pattern as shown in FIG. 23C is knitted. be done.

Next, the pattern creation circuit 128a and the control card 14
The stage feed circuit 128b will be explained with reference to FIG. Reference numeral 129 denotes a direction detecting body, which is provided so as to be movable from side to side within a holding frame 130 provided in the machine frame 23, as shown in FIG. 6, and is configured to move in frictional sliding contact with the belt 50. The direction detector 129 is located at the arrow 68 in FIG.
When the carriage 29 shown moves to the left (the figure shows the direction detection body 129 from the back side), it moves in the same direction as shown by the two-dot chain line to turn off the contact points 131a and 131b, and the line L13b is biased in advance. (1) It has the effect of setting the signal level to zero, and turning on both contacts 131a and 131b when moving in the opposite direction to the right to set the line L13b to the (0) signal level. The line L13b is connected via an inverter 132 to the input side of the first differentiating circuit 133 and directly to the input side of the second differentiating circuit 134, respectively. Therefore, the direction detection body 129 is displaced left and right every time the carriage 29 moves and reverses, and the contacts 131a, 13
Both differentiating circuits 1 each time between 1b and 1b are turned on or off.
For example, a positive pulse is generated from either of 33 and 134, which is supplied via an OR circuit 135 to a constant width pulse generator 136 to trigger it. Then, a pulse of a predetermined width is generated from the constant width pulse generator 136, which excites the ratchet drive coil 138 via the amplifier 137, so that the ratchet ratchet wheel 41 shown in FIG. The control card 14 is advanced by one step each time the carriage 29 reverses its horizontal movement, and the entire surface of the control card 14 is optically scanned as described above. On the other hand, in the pattern creation circuit 128a, 139L,
140L and 141L are left-row AND circuits that receive the (1) signal from line L13b while the carriage 29 is moving in the left direction and enter a half-open state; 139R, 140R, 1
41R is a right-row AND circuit that becomes half open upon receiving (1) signal from the inverter 132 while the carriage 29 is moving in the right direction; 142 is a fixed circuit that selectively contacts the movable contact piece 143 connected to the positive potential terminal; The first changeover switch has contact pieces 143a to 143g, the fixed contact piece 143g is connected to the remaining input terminals of the AND circuits 140L and 139R for left and right rows, and the fixed contact piece 143f is connected to the AND circuits for left and right rows. The fixed contacts 143e and 143d are connected to the remaining input terminals of the left and right AND circuits 141L and 141R, respectively. 144 is an OR circuit 140 that receives signals from the left and right row AND circuits 139L, 139R and the fixed contact piece 143b.
This is an OR circuit that receives signals from L, 140R and the fixed contact piece 143c. An AND circuit 146 receives signals from the line L14 connected to the output end of the pattern creation light receiving element 100a and the OR circuit 144, and a 147 receives signals from the line L15 and the OR circuit from the line L14 via the inverter 148. AND circuit 149 receives the signal from circuit 145 as input, and 149 is both AND circuit 146,
147 and the AND circuit 141 for the left and right rows
This OR circuit 149 receives each output signal from L and 114R, and the output terminal of this OR circuit 149 is connected to the line L11. Such pattern creation circuit 1
The operation of 28a is as described below. That is,
When the gate control disc 99 rotates in conjunction with the movement of the carriage 29, the pattern creation light receiving element 100a
Each time it faces each pattern forming transparent window 100, it outputs a pattern pulse P4 (1) signal and supplies it to the line L14. However, at this time, if the movable contact piece 143 of the first changeover switch 142 is selected as the fixed contact piece 143a which is in the OFF position, the pattern pulse P4 is
cannot pass through, and the line L11 always remains a (0) signal. This corresponds to the state in which the line L7 is always assumed to be a (0) signal in the explanation of the operation in FIGS. 15 to 23. The case where each of the fixed contact pieces 143b to 143g of the first changeover switch 142 is selected will be explained below, but in this case, the pattern selection switch 10
6 is selected and set to the fixed contact piece 107a, and using the control card 14 shown in FIG.
The case where 6 is formed will be explained as an example.

Fixed contact piece 143b of first changeover switch 142
is selected and the interlocking switch 118 is set to the dotted line position, the AND circuit 146 connects the fixed contact piece 143b to the OR circuit 1 at one input terminal.
44, it receives the (1) signal and is placed in a half-open state. Therefore, the pattern pulse P4 output from the pattern creation light receiving element 100a passes through the AND circuit 146, and then the OR circuit 149 and the lines L11, L10, L.
7 to the OR circuit 115 in FIG. This pattern pulse P4 is generated every time the scanning window 90 faces every other pixel area 16, and moreover, as shown in FIG. 17A, the knitting pattern 126 written on the control card 14 is filled in. In addition, since the interlock switch 118 is set to the dotted line position, the output pixel signal P1a supplied to the lines L2a to L2d is a (0) signal, so the inverter 119 converts the output pixel signal P1a and the pattern pulse P4 (which The (0) signal means that no pulse is generated from the pattern creation light-receiving element 100a.) The (1) signal is output only when the (0) signal becomes the (0) signal at the same time. Therefore, as shown in FIG. 24A, a knitted pattern 126 is formed in the knitted fabric 127 in the form of a vertical striped pattern. In contrast, interlocking switch 1
When the knitting operation is performed with the knitting pattern 18 set at the solid line position, a knitted fabric 127 having a filled-in knitting pattern 126 with a vertical striped pattern in the background as shown in FIG. 24B is obtained.

Fixed contact piece 143c of first changeover switch 142
is selected, the other AND circuit 147 instead of the AND circuit 146 receives the (1) signal from the fixed contact piece 143c via the OR circuit 145 and becomes a half-open state, and the AND circuit 147 is connected to the inverter 1.
Since the pattern pulse P4 whose level has been inverted by 48 passes through, the knitted pattern is the second knitting pattern.
The result is the same as that shown in FIGS. 4A and 4B, if it is shifted in the horizontal direction by exactly one pixel area 16.

When the fixed contact piece 143d is selected, the right row AND circuit 141R is always (1) from the fixed contact piece 143d.
After receiving the signal, the carriage 29 is left in the half-open state, and the carriage 29
Only when moving in the right direction, it receives the (1) signal which is the output of the inverter 132, outputs the (1) signal, and supplies it to the line L11 and then to the line L7 via the OR circuit 149. Therefore, line L7 becomes a (0) signal only when the carriage 29 moves to the left, and if the interlocking switch 118 is set to the dotted line position at this time, as will be understood from the explanation regarding FIG. As shown in FIG. A, a knitted pattern 126 with a horizontal stripe pattern is formed on the knitted fabric 127. On the other hand, when the interlocking switch 118 is set to the solid line position, as shown in FIG.
is obtained.

When the fixed contact piece 143e is selected, the left row AAND circuit 141L is always connected to the fixed contact piece 143e.
(1) The signal is received and the carriage 2 is left in the half-open state.
9 receives the (1) signal from the line L13b only when moving in the left direction, outputs the (1) signal, and sends this to the OR circuit 149.
It is now in a state where it is supplied to line L7 via. Therefore, the horizontal striped pattern knitted in this case is the same as that shown in FIGS. 25A and 25B, shifted vertically by exactly one row of stitches.

When the fixed contact piece 143f is selected, the AND circuits 139L and 140R for left and right rows are connected to the fixed contact piece 14.
It is in a half-open state by constantly receiving the (1) signal from 3f, and the (1) signal generated on line L13b when the carriage 29 moves leftward is supplied to the AND circuit 146 via the left-row AND circuit 139L and the OR circuit 144. and leave it half open. Furthermore, when the carriage 29 moves in the right direction, the (1) signal output from the inverter 132 is transmitted to the right AND circuit 140R and the OR circuit 14.
5 to the AND circuit 147, which is kept in a half-open state. Therefore, the light receiving element 100 for pattern creation
The pattern pulse P4 output from a is the carriage 29
When the carriage 29 moves to the left, it passes through one AND circuit 146, and when the carriage 29 moves to the right, the inverter 1
The pattern pulse P4 whose level has been inverted by 48 passes through the other AND circuit 147. In this case, if the interlocking switch 118 is set in advance to the dotted line position, the filled-in knitting pattern 12 on the control card 14 can be
When the carriage 29 moves leftward during scanning in the 6 areas, the line L13a changes to (0) due to the (1) signal pattern pulse P4 that passes through the AND circuit 146.
When the carriage 29 moves in the right direction, the pattern pulse P4, which is a (1) signal, passes through the AND circuit 147, and the line L13a is made into a (0) signal. Since one of the pattern pulses P4 outputted from the AND circuits 146 and 147 has been inverted in level in advance by the inverter 148, their phases are different by 180 degrees. Knitted fabric 127 as shown in the enlarged view of the stitches
The pattern in the upper knitting pattern 126 area is such that stitches of different colors are scattered in a staggered manner, and the knitting pattern 126 is knitted based on this dotted pattern as shown in FIG. 26A. In contrast, the interlocking switch 118
If it is set to the solid line position, Fig. 26B
A knitted fabric 127 having a filled-in knitting pattern 126 with a dotted pattern in the background is obtained as shown in FIG.

When the fixed contact piece 143g is selected, the other left and right row AND circuits 140L and 139R are connected to the fixed contact piece 1 for the AND circuits 139L and 140R.
The line L1 is made half open by the (1) signal from 43g and is generated when the carriage 29 moves to the left.
3b passes through the left-row AND circuit 140L, and during rightward movement, the (1) signal from the inverter 132 passes through the right-row AND circuit 139R. Therefore, when the carriage 129 moves to the left, a dotted pattern is knitted based on the pattern pulse P4 whose level has been inverted by the inverter 148, and when the carriage 129 moves to the right, it is knitted based on the pattern pulse P4 outputted from the pattern creation light receiving element 100a. A dotted pattern will be organized based on this.

Next, a third embodiment will be explained with reference to FIG. 27. The overall electrical configuration of this third embodiment is as follows.
This corresponds to the circuit shown in FIG. 27 combined with the circuit shown in FIGS. 13 to 13. FIG. 27 shows the pattern reversal circuit 150, and FIGS.
The combination with the figure is done as follows. That is, the 11th
Each of the relay terminals LIa to LId shown in the figure is connected to each input terminal of one OR circuit 151 shown in FIG. 27, and the relay terminals LIa, LIb, LIe, and LIf are connected to each input terminal of the other OR circuit 152 shown in FIG. Connect to input terminal.
Further, the relay terminals CT5 and CT6 in FIG. 12 are connected to the relay terminals having the same reference numerals in FIG. 27 after removing the line L13 connected therebetween. The pattern reversal circuit 150 includes AND circuits 153 to 162, OR circuits 151, 152 and 163 to 165, inverters 166 to 168, and a second changeover switch 169, and the second changeover switch 169 is a movable switch. 170 and fixed contact pieces 170a to 170f that are selectively brought into contact with this and given a positive potential.

Next, the operation of the pattern reversing circuit 150 having the above configuration is as follows.
An example will be explained in which the pattern selection switch 106 is set to the fixed contact piece 107a, the first changeover switch 142 is set to the fixed contact piece 143a, and the control card 14 shown in FIG. 17A is used. . Fixed contact piece 170 of second changeover switch 169
When a is selected, the AND circuit 162 receives the (1) signal from the fixed contact piece 170a via the OR circuit 164, and is kept in a normally half-open state. Therefore line L1
The output pixel signal P1a, which is the (1) signal outputted to the 28th
Knitted pattern 12 formed on knitted fabric 127 as shown in the figure
6 is the color knitted with pattern knitting yarn.

Fixed contact piece 170b of second changeover switch 169
is selected, the AND circuit 161 receives the (1) signal from the fixed contact piece 170b via the OR circuit 163, and is kept in a normally half-open state. Therefore, the output pixel signal P1a supplied to the line L12 is inverted in level by the inverter 168 and then supplied to the relay terminal CT6 via the AND circuit 161 and the OR circuit 165, as shown in FIG.
The color relationship between the knitting pattern 126 and its background is the second.
It is organized in such a way that it has the opposite relationship to that in Figure 8.

When the fixed contact piece 170c is selected, AND circuits 153 and 155 (1) from the fixed contact piece 170c
It is always kept half open by a signal. Therefore, the AND circuit 162 outputs the gate timing signal P2a only during the first two rotations of the four rotations of the scanning drum 43.
The AND circuit 1 is brought into a half-open state by P2d.
61 is kept in a half-open state only during the latter two rotations due to the presence of the inverter 166. As a result, the output pixel signal P1a supplied to the line L12 during the first two rotations of the scanning drum 43 passes through the AND circuit 162 as it is, and is further supplied to the relay terminal CT6 via the OR circuit 165. As shown in Fig. 30, one unit portion 127a (equivalent to 32 knitting needles with 25 needles) located on the right side of the knitted fabric is knitted in the same color relationship as in Fig. 28, and one unit portion 127a located on the left side 127b is knitted in the same color scheme as in FIG. 29.

When the fixed contact piece 170d is selected, the AND circuits 154 and 156 are always kept half open. Therefore, the AND circuit 161 is kept in a half-open state by the gate timing signals P2a to P2d only during the first two rotations of the scanning drum 43, and the AND circuit 16
2 is kept in a half-open state only during the latter two rotations due to the presence of the inverter 166. This relationship is exactly the opposite of the relationship when the fixed contact piece 170c is selected, and the fabric is knitted in a state with a color relationship as shown in FIG. 31.

When the fixed contact piece 170e is selected and the pattern selection switch 106 is set to the fixed contact piece 107e, and the control card 14 shown in FIG. 22A is used,
The AND circuits 157 and 159 are always kept half-open, so that only the gate timing signals P2a, P2b, P2e, and P2f that receive the OR circuit 152 act effectively. Therefore, the AND circuit 159 receives gate timing signals P2a and P2.
Only when signal b, P2e, or P2f occurs, the signal (1) is output to leave the AND circuit 162 in a half-open state. Furthermore, due to the presence of the inverter 167, the AND circuit 157 receives gate timing signals P2a, P2b,
Only when P2e and P2f disappear, the signal (1) is output to bring the AND circuit 161 into a half-open state. Therefore, the output pixel signal P1a supplied to line L12
is the first rotation among the four rotations of the scanning drum 43.
AND circuit 16 without level inversion at RT1
2, and inverter 168 at the second rotation RT2.
It passes through the AND circuit 161 with the level inverted by
Then, the signal passes through the AND circuit 161 while being inverted in level by the inverter 168. Therefore, the knitted fabric 127 has 16 knitting needles 2 as shown in FIG.
5 is one unit, and the color arrangement is alternately reversed. On the other hand, the fixed contact piece 170f
is selected in the same way, AND circuit 1
58 and 160 are normally kept in a half-open state, and as a result, the AND circuit 161 is kept in a half-open state by the gate timing signals P2a, P2b, P2e, and P2f, and the AND circuit 162 is set in a half-open state by the gate timing signals P2a, P2b, P2e, The disappearance of P2f causes it to be in a half-open state. This is fixed contact piece 170
The relationship is exactly opposite to that when e is selected, and therefore, as shown in FIG. 33, the color arrangement is exactly opposite to that shown in FIG. 32.

FIG. 34 shows an application example. In the knitted fabric 127 shown in FIG. 34, an area 127A has a diamond-shaped vertical striped pattern (portion 127d) which is shifted by one pitch with the knitting needle 25 from the vertical striped background pattern (portion 127c).
The area 127B is organized in a manner that expresses the
This knitting pattern has a diamond-shaped vertical striped pattern (part 127f) vertically shifted by one stitch row from the horizontal striped background pattern (part 127e). The organization of the area 127A is, for example, the second
The OR circuit 16 is added to the AND circuits 161 and 162 shown in FIG.
The pattern pulse P4 described above in place of 3,164
This is possible if configured to supply
The organization of the region 127B can also be made possible by supplying a signal on the line L13b in which the signals (0) and (1) are inverted in relation to the left and right rows of the carriage 29 described above.

In knitting the knitted fabric 127 according to another application example shown in FIG. 35, for example, the knitted fabric 127 shown in FIG. 35A is knitted by applying the principle shown in FIG. A circuit for dividing into the group P2e to P2h is added to the pattern creation circuit 128a in FIG. Gate timing signal P2e at 127D
This can be realized by using a configuration in which the signals are added by P2h to P2h and erased by gate timing signals P2a to P2d in the region 127E. According to this configuration, when the interlocking switch 118 is set to the dotted line position, the signal shown in FIG. Each area 127
A knitting mode as shown in F, 127G is obtained.

Next, a fourth embodiment of the present invention will be described. The fourth embodiment is a combination of the circuits shown in FIGS. 11 to 13 with a signal distribution circuit 171 shown in FIG. 36. This signal distribution circuit 171 includes AND circuits 172a to 172h, 173a to 173h, 174a to 174h, 175a to 175h, and OR circuits 176a to 176h.
It consists of a third changeover switch 177. The third changeover switch 177 consists of a movable contact piece 178 and fixed contact pieces 178a to 178d that are selectively contacted by the movable contact piece 178 and receive a positive potential. The combination of this signal distribution circuit 171 and the circuit shown in FIG. 11 is such that after removing the intermediate lines L4a to L4h shown in FIG. 11, the relay terminals LIa to LIh shown in FIG.
This is done by connecting LOa to LOh to the relay terminals in FIG. 11 indicated by the same reference numerals. With such a configuration, the signal distribution circuit 17
1 are gate timing signals P2a to P2 supplied to lines L3a to L3h in this order.
This is for distributing and outputting h to the lines L5a to L5h according to the setting position of the third changeover switch 177, and this relationship is shown in FIG. 37. That is, according to the wiring shown in FIG. 36, as shown in column "178a" in FIG. 37, when the third changeover switch 177 is set to the fixed contact piece 178a, the AND circuits 172a to 172h are set to the fixed contact piece. Gate timing signals P2a to P2h supplied to the signal distribution circuit 171 from lines L3a to L3h via relay terminals LIa to LIh are kept in the half-open state in response to the (1) signal from 178a, respectively. OR circuits 176a to 176h are generated by certain AND circuits 172a to 172h.
are distributed to lines L5a to L5h.
This is the same as the state of the second embodiment described above in which the signal distribution circuit 171 is not used and the relay terminals LIa to LIh and LOa to LOh are short-circuited by intermediate lines L4a to L4h. Based on the same principle as when the fixed contact piece 178a of the third changeover switch 177 is selected, the AND circuits 173a to 173h are activated when the fixed contact piece 178b is selected, and the AND circuit 17 is activated when the fixed contact piece 178c is selected.
4a to 174h select the fixed contact piece 178d, the AND circuits 175a to 175h are respectively kept in a half-open state as shown in FIG. 37. The relationship between the gate timing signals P2a to P2h at the respective selected positions of the fixed contact pieces 178b, 178c, and 178d and the lines L5a to L5h to which they are distributed and supplied is "17" in FIG.
8b", "178c", and "178d". In this way, by setting the third changeover switch 177, lines L5a to L5
The gate timing signals P2a to P2h distributed and supplied to h in various manners are further distributed to final stage AND circuits 114a to 114d by various settings of the pattern selection switch 106 in the circuit shown in FIG. As a result, enabling and disabling of opto-electrical scanning of the scanning windows 90a to 90h is controlled in the same manner as described in the second embodiment. In this fourth embodiment, the pattern selection switch 106 is connected to the fixed contact piece 1.
The case where 07b is selected is taken as an example. Therefore, when the third changeover switch 177 is set to the fixed contact piece 178a, as shown in the column "178a" in FIG. 37, the gate timing signals P2a to P2h
The scanning windows 90a, 90f, 90c,
The photoelectric scans 90h, 90d, 90g, 90b, and 90e are enabled in this order, which is the same as shown in column "107b" in FIG. 14 in the second embodiment. And other fixed contact pieces 178b, 17
When 8c and 178d are selected, the order in which the photoelectric scanning of the scanning windows 90a to 90h is activated is "178b", "178c", and "17" in FIG. 37, respectively.
8d" as shown in each column. As can be understood by comparing the activation order of the scanning windows 90a to 90h shown in the columns "178a" to "178d" in FIG. 37, the fixed contact pieces 178a to 178d are No matter which setting is made, the relative activation order of each scanning window 90a to 90d does not change (this is because this relative activation order depends only on the pattern selection switch 106).
However, the correspondence between the generation periods of the gate timing signals P2a to P2h and the activation periods of the scanning windows 90a to 90h is determined by the fixed contact piece 17.
As the settings are changed to 8a, 178b, 178c and 178d, two scanning windows each, i.e.
It can be seen that the relationship is such that the 16 pixel areas are shifted by 16. FIG. 38 shows that in this fourth embodiment, the pattern selection switch 106 is connected to the fixed contact piece 107b using the control card 14 shown in FIG. 16A.
The knitted fabric 127 is shown in an area corresponding to 64 pitches with the knitting needles 25 when the knitting operation is performed while the setting is kept as is and the third changeover switch 177 is sequentially switched. In FIG. 38, each DT indicates a section corresponding to 16 pitches of knitting needles 25. The area 127H in FIG. 38 is the fixed contact piece 178a.
This shows the knitting state when , which is naturally the same as FIG. 16B. Fixed contact piece 1
When 78b is selected, the knitting pattern 126 is shifted left and right by 16 pitches as shown in the area 127I. Similarly, when the fixed contact piece 178c and the fixed contact piece 178d are set sequentially each time the knitting of a certain area is completed, the knitting pattern 126 shifts to the left and right by 16 pitches as shown in the area 127I.
As shown in areas 127J and 127K in the figure, knitting pattern 1
26 are arranged one after another, shifted by 16 pitches. In this way, various types of knitting patterns can be knitted while using the same control card 14 by setting the combination of the third changeover switch 177 and the pattern selection switch 106. Of course, by making combination settings using the first to third changeover switches 142, 169, 177, the pattern selection switch 106, and the interlocking switch 118, even more various knitting patterns can be knitted.

As described above, the present invention provides an apparatus for creating a control card used, for example, as in the second to fourth embodiments. A recording medium that records and displays the knitting pattern based on the difference in ratio, a projection device that optically projects the knitting pattern on the recording medium, and a needle bed that is installed at the projection position of the knitting pattern projected by the projection device. The control card is composed of a control card that clearly indicates the pixel areas corresponding to the knitting needles arranged in a row, and a writing instrument for appropriately writing pixel signals for knitting needle selection in each pixel area of the control card. The knitting pattern on the recording medium is projected onto the recording medium, and the relative positional relationship between each pixel area of the control card and the projected knitting pattern becomes clear, and the projected knitting pattern is determined using the clearly defined relative positional relationship as a guide. Since it becomes possible to write pixel signals according to the following, the writing process does not require much attention, and it is also possible to prepare a large number of recording media displaying different desired knitting patterns in advance and select and use them arbitrarily. is also possible. Second
Since the control card is transparent or semi-transparent, pixel signals can be written on the other side using the knitting pattern projected on one side of the card as a guide, making it easy to trace the projected image and make the writing process easier. Become.

Thirdly, a step feed hole is provided on both sides of the control card to advance the signal when reading the signal on the card, and when the control card is created and installed at the projection position of the projection device, the step feed hole is provided on both sides of the control card. Since it is configured to use the hole for positioning,
When creating a large number of control cards with different knitting patterns, the reference positional relationship between the pixel area on the card and the projected knitting pattern is always constant, making it easier to predict the pattern position on the knitting surface. An excellent effect can be obtained in that the production work becomes extremely easy.
