Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand knitting machine equipped with a needle switch.

The needle switch used in the present invention shares the search plate, which is one component of the lotus needle device, with its position detection switch. Conventionally, when moving a pattern, the amount of movement was determined by a dial, but since the movement of the main hook pattern is expressed on the needle bed, a dial located far away could not correspond to the pattern * .

Another disadvantage is that the larger the amount of movement, the more difficult it becomes to deal with it. Moreover, in order to use the dial to set the movement on the needle bed (1 to 25 books), the dial requires a large number of steps, 25 steps.
The drawback was that it could not be operated with one touch. Furthermore, even if the system is constructed by using switches such as a keyboard, it is necessary to press the key twice or prepare 23 keyboard switches, making it necessary to add additional equipment, which has the disadvantage of increasing costs. . The present invention was proposed to solve the above-mentioned conventional drawbacks, and includes a plurality of knitting needles supported movably back and forth and up and down on a needle bed, a carriage movably installed on the needle bed, In a hand knitting machine equipped with a needle selection device that selects or non-selects the knitting needles in response to a designation signal read out from a pattern storage medium in response to a readout instruction signal accompanying movement of the carriage. , a needle switch for detecting a pressing operation of the knitting needle; a register for storing the signal of the needle switch as a pattern movement signal; and a pattern setting means for reading out a setting signal from the storage medium, and the amount of movement of the pattern is determined by pressing the knitting needle after selecting the needle block number on the needle bed.
To provide a hand knitting machine equipped with a needle switch capable of easily and surely moving a pattern with one touch.

Embodiments of the present invention will be described below with reference to the drawings.

First, the basic configuration of a hand knitting machine showing an embodiment of the present invention will be explained. This hand knitting machine electronically controls the key needle mechanism of the home line machine shown in FIG. The knitting needles 2 are arranged side by side so that they can be moved up and down and back and forth.The knitting needles 2 are normally placed in the upper direction as shown in ■ by the leaf spring 3 and are in a high butt state.They also move left and right on the needle bed 1. A batt-down member 5 is installed on the carriage 4 for knitting, and only the knitting needles are pushed down as shown by @, and the non-knitting green needles do not pass through the batt-down member 5, so they are not rolled down.7. 1 is a plate support member in which eight handle plates GI to G8 and five search plates KI to K5, which are one of the key points of the present invention, are attached to face the knitting needles 2.

There are also switches OSI to GS8 and KSI for detecting the positions of handle plates GI to G8 and search plates KI to K5, respectively.
~KS5 is installed. Here, the knitting needle 2 is
When it is pressed down as in the above, one of the handle plates GI to G8 and at least one of the search plates KI to K5 are moved in the longitudinal direction. SLI~8 is a solenoid attached to the solenoid support member 55, and a plunger PLI~8 moves the handle plate GI~G8 that has been moved according to the electrical input.
, and held at the position moved by SBI~8. Second
The figure is a diagram of the electronic needle selection control system of the knitting machine shown in FIG. However, as shown in FIG. 3, the handle plates GI to G8 are provided with protrusions as shown in circles 20 corresponding to needle numbers 1 to 8 of each block.

This protrusion is provided with a first cam surface 21, and the handle plates GI to G8 are always biased toward the left in FIG. 3 by a spring. Side 2
1, the handle plate corresponding to the number of the knitting needle 2 moves to the right in the figure. In addition, as shown in FIG. 4, the plate support plate 7
The handle plates GI to G8, which are held so as to be laterally movable by the plate support rod 8, are provided with small holes CHI to G8, respectively.
As a result, when the handle plate moves to the right in the figure, the switches GSI-GS8 are actuated via the levers GLI-8, and the controller 00 is inputted as shown in FIG. On the other hand, the search boards KI to K5 are provided with protrusions as shown in circles 30 corresponding to each block of which the needle numbers 1 to 8 of the knitting needles 2 are one block, as shown in FIG. That is, with the relationship as shown in FIG.
Same. It is provided corresponding to all of the knitting needles 2 of the rack,
. Further, an inclined cam 31 is provided on the protrusion, and when the knitting needle 2 is pressed down and acts on the cam 31, each search plate moves to the left in the figure. On the other hand, search board K. -1 to K5 are also provided with small holes KHI~5, respectively, as shown in Fig. 4, so that when the search board moves to the left in the figure, the switch KSI~ is opened via the lever KLI~5. KS5 is applied and input to the controller 1000 as shown in FIG.

The search plates KI to K5 are always biased to the right in the figure via the levers KLI to 5 by the spring force of the switches KSI to KS5, respectively, but the positioning bar 51 and each elongated hole 5
2 restricts the horizontal movement of the handle plates GI to G8. Similarly, the search boards KI to K5 are also connected to the positioning rod 51 and each elongated hole 53.
Lateral movement is restricted by As above, search board K
Since I to K5 and handle plates GI to G8 are configured, for example, when the fifth knitting needle 2 of the 21st block is pressed down, switches KS1, KS3 and KS5 act according to the relationship shown in FIG. Switch GS5 operates in this connection.

In controller 000, the switches KSI to KS5
The block can be detected by the code signal of
The needle number in that block can also be known from the switches GSI to GS81. Next, the configuration of the controller 1000 shown in FIG. 2 will be explained.
S8 is a leading needle detection circuit 100 and a non-rolling detection circuit 6001.
This is connected. The leading needle detection circuit 10 is connected to a lowering start detection circuit 200, a block movement direction detection circuit 300, and a timing circuit 800'. 600 is a non-rolling detection circuit connected to the rolling start detection circuit 200, the flock movement direction detection circuit 300, the block detection circuit 400, and the stage detection circuit 700. The block moving direction detection circuit 300 is connected to the block detection circuit 40.

Further, the block detection circuit 400 and the stage detection circuit 700 are connected to a read-only memory (hereinafter referred to as ROM) 5001, and the output thereof is connected to a timing circuit 80.
The output of 00 is the non-pressure detection circuit 600 and the drive circuit 90.
0' is connected. The drive circuit 900 is the controller 1
It is connected to solenoids SOLI to SOL8 as the output of 000. Further, as shown in FIG. 6, there are S camellia SBI~ between the small holes GWI~GW8 of the handle plates GI~G8, the small holes HI~8 provided in the plate support member 7, and the small holes of the plungers PLI~PL8, respectively. If SB8 is provided and the handle plate is in the normal position, the positional relationship will be S pole SB7, and if the handle plate is moved to the right in the figure by the depressed green needle 2 as described above. This is the positional relationship of S-SB8. When this relationship exists, when a solenoid drive signal is generated by the timing circuit 800, the drive circuit 90 is increased in power, and current is caused to flow through the solenoid SOL8, for example. Also, the plunger PL8 is attracted by the solenoid SOL8, and the handle plate G
8 is held in this position. The locking action of the knitting needle 2 in this case will be explained with reference to FIGS. 7 and 8, in which the protrusion of the handle plate is viewed from the direction of the solenoid. The knitting needles 2 are rolled down by a rolling member 5 as shown in FIG. Note that the striped needle state a...i in FIG. 9 is the striped needle state 1... skin in FIGS. 7 and 8, and b→1, c→0, d. →m,
e→W, f→V, g→, h→blood, almost corresponding. Now, at 1 in Fig. 7, the knitting needle 2 is pushed down by the shoring member 5, and finally, as shown at 0, the handle plate is moved to the left by the first cam surface 21 against the urging force A of the handle plate. . Handle plate GI
~G8 is S Korea SB by spring SPI ~8 in Figure 6
The handle plate is always energized in the A direction via I to 8. Here, in the row position, the switch corresponding to the handle plate among the switches GSI-8 acts, and in the position m, the knitting needle 2 is rolled down to the lowest position. In this case the switch remains active and
The solenoid relationship is as in the plunger PL8 shown in FIG. Then, when the pressing member 5 passes as shown in W, the knitting needle 2 is returned upward by the small force A of the handle plate and the spring 3, and the handle plate also returns to its original position with the movement of the knitting needle 2.
V, W, and skin are completely restored and the switch becomes inactive, and the solenoid relationship is restored to the state of plunger PL7 in FIG. 6. In this case, the knitting needles 2 are in the state f in FIG. 9, and are sorted into the state h by the first cam 11 of the sorting cam 10. In FIG. 8, the operation is the same as in the case of FIG. By applying force, the handle plate is held at a position where the positioning bar 51 and the elongated hole 52 in FIG. 3 are in contact with each other. In this case, even if the lowering member 5 passes as indicated by N and V, the knitting needle 2 is prevented from returning upward by the second cam 22 and remains locked in the downward position, and the switch also remains activated. . Next, a signal from the timing circuit 800 causes the solenoid '
When this current stops flowing, the knitting needle 2 returns upward due to the urging force A of the handle plate and the spring 3, and the switch becomes inactive. This tin-combined knitting needle 2 is in the state g in FIG. 9, and is sorted into the state i by the second cam 12 of the sorting cam 10. Further, in FIG. 2, the line needle 2 is controlled to be locked and unlatched as shown by ■, and the needle is selected as shown by the selection cam 101 provided on the carriage 4. Further, to explain the controller 1000 in detail, the leading needle detection circuit 10
As shown in FIG. 9, a plurality of knitting needles 2 are pressed down by the pressing member 5, and the handle plate is moved to the switch GSI as shown in FIG.
~8 may be held in the position where switch G
SI~8 is always the rolling member 5 even when multiple pieces act.
This circuit detects the signal of the switch GSI-8 corresponding to the number of the newly pressed knitting needle 2.

In addition, when the knitting needles 2 are located below the knitting needles 2, the knitting start detection circuit 200 may not be able to detect the correct code signal because the switches KSI to KS5 may straddle two block numbers when a plurality of knitting needles 2 are located below. This is a circuit that detects the state in which the knitting needle 2 is in the downward position, that is, the pressing member 5 has pressed down the knitting needle 2 for the first time in knitting that row (in other words, in that case, the correct block number code of the green needle 2 is detected) The switch (KSI~5) represents the signal). Furthermore, as shown in FIG. 3, the block moving direction detection circuit 300 increases the block number when the number of knitting needle 2 changes from No. 8 to No. 1, and when the number of knitting needle 2 changes from No. 1 to No. 8. is a circuit that detects a change in the block of the knitting needle 2 newly rolled down by the rolling down member 5, paying attention to the decrease in the block number. Next, the block detection circuit 4001 and the rolling start detection circuit 2
When a signal of 00 is generated, the code signals of the switches KSI to KS5 are read and stored as the block number of the knitting needle 2 that was rolled down first. And block moving direction detection circuit 3
When a block number increase signal is generated from 00, 1 is added to the stored block number and stored, and when a block number decrease signal is generated from the block movement direction detection circuit 300, 1 is subtracted from the stored block number. This circuit always outputs the block number of the knitting needle 2 newly rolled down by the rolling down member 5 by storing it as a new block number. The ROM 500 corresponds to a conventional punch card that stores the needle selection state of each block in each number of stages in advance, and the ROM 50 has a block detection circuit 4.
00 and the output of the stage detection circuit 700 are used as address inputs, and a pre-stored 8-bit output corresponding to the address input is generated. This 8-bit output corresponds to the number of knitting needles 2 in each block. That is, ROM50
0 stores the mist needle state of each block at each stage number and outputs the needle selection state according to the stage number and block input. Also, the non-sho bottom detection circuit 600 is a switch GS.
It detects that none of I to GS8 is acting and detects that the rolling member 5 has finished rolling down the knitting needles. However, if the solenoids SOLI to SOL8 are acting, the switches GSI to GS8 continue to act, so it may not be possible to detect the end of pressure reduction, so the timing circuit 8
The relationship between the timing of 00 and the energization signal to the solenoids SOLI-8 is corrected so that even if any of the solenoids SOLI-8 is activated and the switch is activated, the end of the down cycle can be detected. The stage detection circuit 700 is a circuit that adds one stage based on the one-stage knitting completion signal from the non-rolling detection circuit 600, and detects the number of stages at which the needle selection state should be output. Further, the timing circuit 800 is configured such that, for example, when the No. 1 knitting needle 2 of the 2nd block is pressed down and enters the state shown in FIG. When the No. 2 knitting needle 2 is pressed down and the switch GS2 is activated, the No. 1 green needle 2 of the second block enters the state m in FIG. 8, and the solenoid SOLI is energized. Next, when the No. 3 knitting needle 2 of the 2nd block is pressed down and the switch GS3 is activated, it becomes the state W in Fig. 8, and the solenoid SOLI
energized, then knitting needle 2 of No. 4 of 2 blocks.
When the switch GS4 is pressed down and the switch GS4 is activated, the state shown in FIG. 8 is reached, and the solenoid SOLI is still energized. Next, when the No. 5 knitting needle 2 of the second block is pressed down and the switch GS5 is activated, the solenoid SOLI is de-energized and no current flows, resulting in the state shown in FIG. In this way, the leading needle detection circuit 1 determines the timing of energizing the solenoids SOLI~8 corresponding to each handle plate GI~G8.
It is determined by the output of 00, and the solenoids SOLI-8 are energized according to the output of the ROM 500. Next, the non-pressure detection circuit 60
When a 0 signal is generated, all the currents to the solenoids SOLI-8 are stopped. In addition, the drive circuit 90 and the timing circuit 800
The output is increased and given to solenoids SOLI~8. FIG. 10 shows an electric circuit diagram of the controller 1000, in which one end of the switches OSI to GS8 of the handle plate GI to 8 is connected to a power source, the other end is grounded via resistors 91 to 98, respectively, and the leading needle It is connected to the inputs of the detection circuit 100 and the non-pressure detection circuit 600, and the switch GSI~

The power supply relationship of each element is omitted. The circuit configuration described above has been made easy to understand for the convenience of explanation, but in reality, a microcomputer performs program control that performs the same function, and although the explanation will be omitted, excluding the drive circuit 900, there is only one circuit configuration.
It can be configured with a chip, which is advantageous in terms of cost and space. Next, the operation of the embodiment described above will be explained.
An example of knitting up to knitting needles 2 of No. 3 of a block will be explained. It is also assumed that the ROM 500 stores the needle selection states shown in Table 1 below.・However, 1: In FIG. 9, the knitting needle 2 is locked as shown in g, and the second cam 12 selects. 0: In FIG. 9, the knitting needle 2 is not locked as shown in f, and the first cam 11 So, the first stage is 1 block.

Assume that the carriage 4 is moved in the direction of two blocks from the direction of the block, and first, in FIG. do. Further, the lower member 5 of the carriage 4 is passed through blocks 1, 2, and 3 of one block, but the green needles are not rolled down because they are non-knitted needles. Therefore the switch OSI~GS
8 remains off, AND element 611618 in FIG. 12 does not hold AND and becomes inactive.
Since the OR of OR element 621 also does not hold, the OR element becomes inactive. In addition, since the inverter element 631' has an inverting action, the circuits 200, 300, 400 and the timing circuit 800 are reset. In FIG. 16, the OR element 813 of each timing circuit 801 to 808 is in an operating state as OR is established, and the F. F815 is reset and its 8 outputs become inactive, AND element 816 becomes inactive because the AND is not established, and drive circuit 90
1-908 are also inactive, and solenoids SOLI-8 are not energized. Next, the carriage 4 moves further and finally presses down the knitting needle No. 6 of one block. Further, the handle plate G6 and the search plate KI move in the relationship shown in FIG. 3, and the switches OS6 and KSI act. Non-pressure detection circuit 600
In FIG. 12, the switch GS6 is active. The output P6 of the timing circuit 806 remains inactive, the inverter element 606 is active, and the AND element 616 is also active.
The OR element 621 becomes operative when the OR is established, and the inverter 631 becomes inactive. Therefore, the circuits 200, 300,
Release the reset state of 400 and 800. Further, in the leading needle detection circuit 100 in FIG. 11, the switch GS6 is activated, the single mark 106 is also activated, and GM6 outputs a short-time signal. On the other hand, since the output GM6 is applied to the reduction start detection circuit 200 in FIG.
A set input is generated in 202, and its 8 outputs change from inactive to active, and the single mark 203 outputs a short-time signal TOP.In the flock movement direction detection circuit 30, the output AR is activated in Fig. 14. Since it became inactive, F・F3
04 and 305, the reset input changes from action to non-action, but since no set input occurs, all eight outputs remain non-action, and AND is not established for both AND elements 305 and 306, and the outputs L and R Both have no effect.

Block detection circuit 40 output TOP in Figure 10
The load input acts due to the action of , and the states of inputs KSI to KS5 are set to outputs BI to B5 as they are, and the outputs become 1,0.
,0,0,0, which means one block. The stage detection circuit 700 does not count up when the output AR changes from action to inaction, and the outputs AI to A7, which mean the first stage, are 0, 0, 0.
,0,0,0,0. In the ROM 500, the address input of the first block of the first stage acts, and according to Table 1, the outputs RI to R8 are 0, 1, 0, 1, 0, 1, 0.
, 1. In addition, in the timing circuit 802, the OR of the OR element 813 is established in FIG. 16, and the reset input is still acting on the F/F 815 as it is dependent on heat, and the 0 output is inactive, and the AND element 816 is also inactive and output. P2 becomes inactive and solenoid SOL2 is not energized. In FIG. 16, the timing circuit 806 has output R6 acting and output G
M6 is also an effect, and AND element 812 is established, and F
- The set input acts on F815, and the a output becomes active, but the output GM6 also causes the reset input to act on F.F814, so the 8 outputs of F.F814 become inactive, and the AND element 816 becomes Since it does not hold, output P6
is inactive and solenoid SOL6 is not energized.
Also, timing circuits 801, 803, 804, 805, 8
07 and 808 in FIG. 16, F/F815 is still in the reset state because no set input occurs, and 808 is still in the reset state.
Output is inactive, AND element 816 is also inactive, output P1,
P3, P4, P5, P7, and P8 are also inactive, and all solenoids SOLI to SOLI8 are not energized. Next, carriage 4
With this movement, when the pressing member 5 presses down the next green needle 2, that is, the knitting needle No. 7 of one block, the handle plate G7 is newly moved and the switch GS7 is activated. In the leading needle detection circuit 100, as shown in FIG. 11, when the switch GS7 is activated from its inactive state, the single mark 107 is activated, and a short-time activation signal is generated at the output GM7. In the non-pressure detection circuit 600 in FIG. 12, switch GS7 is activated and timing circuit 807 is
Since the output P7 remains inactive, the inverter element 6
07 becomes an effect, the AND element 617 becomes an effect and the AND is established, the OR element 621 continues to act as the OR remains true, and the inverter 631 remains inactive, that is, the output AR remains inactive. .

In the rolling start detection circuit 20, the output AR is shown in Fig. 13.
Since is inactive, F・F202 is in the set state,
Since its 8 outputs remain active, the single circle 203 has already become non-active, and its output TOP has become non-active. In addition, the block moving direction detection circuit 300 is shown in FIG.
Both F303 and 304 remain in the reset state because the set input is not acting on them, and both 0 outputs are inactive, AND elements 305 and 306 do not form an AND, and outputs L and R are inactive. It remains as it is. In FIG. 10, the block detection circuit 400 has an up input, a down input,
Neither the load input nor the reset input acts, and the outputs BI to B5 retain 1, 0, 0, 0, 0, and remain as outputs representing one block. In the stage detection circuit 70 shown in FIG. 15, none of the reset input, down input, and up input act, and the outputs AI to A7 are 0, 0, 0.
, 0, 0, 0, 0, and remains the output meaning the first stage. Since the address inputs of BI~B5 and AI~A7 of ROM500 do not change, the outputs RI~R8 are 0, 1,
It remains as 0,1,0,1,0,1.

In the timing circuits 801 to 805, 807, and 808, as shown in FIG. However, the AND element 816 does not hold the AND, and its output P1~
P5, P7, P8 become inactive, solenoid SOLI
~5, 7, and 8 are not energized. Also, timing circuit 806
is the output G which is the input of the OR element 813 in FIG.
Since M2 and the output AR are both inactive, the OR is not established and their outputs remain inactive, F.F815 maintains its set state, and its 8 outputs remain active. On the other hand, the output GM7 of the outputs GM5 and GM7, which are the inputs of the OR element 811, acts as an effect and the OR is established.The output acts as an effect and gives a set input to F●F814, and its output also acts as an effect. The AND of element 816 is established and output P6 acts, energizing solenoid SOL6 via drive circuit 906. Therefore, the handle plate G6 and the No. 6 knitting needle 2 of one block are in the state m shown in FIG. Next, when the number 8 knitting needle 2 of one block is pressed down, the handle plate G8 is newly moved,

The solenoids that are energized at this time are SOL1, SOL2,

21 has no effect because the OR is not established, and the output AR, which is the output of the inverter 631, has an effect. Since there is no newly activated switch in the leading needle detection circuit 10, all of the outputs GMI to GM8 are inactive. In FIG. 13, the reduction start detection circuit 200 detects F and F2 by the output AR.
02 is reset and its 0 output changes from action to non-action, but the single mark 203 does not work and the output TOP remains inactive. In FIG. 14, the block moving direction detection circuit 300 operates OR elements 301 and 302 by the action of output AR, resets F and F 303 and 304, and sets those 8 outputs inactive to operate AND elements 305 and 306.

15 is reset, the a output becomes inactive, and the outputs PI to P8, which are the outputs of AND element 816, also become inactive,
All solenoids SOLI-8 are not energized. In this way, the knitting needles are locked downward and the numbers 6 and 8 of the first block and the numbers 1 and 2 of the second block are sorted out by the second cam 12 shown in FIG. The knitting needle No. 3 is not locked downward and is selected by the first cam 11 shown in FIG. This completes the first stage of needle selection, and then the carriage 4 moves from the second block to the first block to begin the second stage of needle selection. As the carriage 4 moves, the No. 3 knitting needle 2 of the second block is rolled down by a reverse direction rolling member (not shown).

As a result, handle plate G3 and search plate K2 move in the relationship shown in FIG. 3, and switches GS3 and KS2 act. In the non-reduction detection circuit 60 shown in FIG. 12, the switch GS3 is in effect. Since the output P3 is inactive, the AND element 613 is in effect, the OR element 621 is in effect, and the output AR, which is the output of the inverter 631, is in effect. It becomes inactive.Top needle detection circuit 1

Therefore, the OR element 201 also acts, the set input acts on the F/F 202 which was in the reset state, its 8 outputs change to the effect, and the single ring 203 outputs a short-time action signal TOP.Flock movement direction In the detection circuit 300, in FIG. 14, the F/Fs 304 and 305 are in a reset state because the set input does not act, and the respective eight outputs are inactive, and the outputs L, which are the outputs of the AND elements 305 and 306, are in the reset state. R remains inactive. In the block detection circuit 400, the load input acts on the output TOP in FIG.
The state of KS5 is set as is, 0, 1, 0, 0,
It becomes 0, meaning 2 blocks. The stage detection circuit 700 does not act on the reset input, down input, or up input, and the outputs AI to A7 hold 1, 0, 0, 0, 0, o, 0. In the ROM 500, the address input of the second block in the second stage acts, and according to Table 1, the outputs RI to R8 are 0,
0, 1, 1, 0, 0, L1.

In addition, the timing circuit 803 is connected to the departure GMI in FIG.
The AND element 812 is operated by the action of R3, and F.
F815 is set to make its 8 outputs act, while F/F814 is reset by the action of departure OMI to make its 8 outputs inactive, and P3, which is the output of AND element 816, is made inactive, Solenoid SOL3 is not energized. Also, timing circuits 801, 802, 804 to 80

In addition, when the No. 8 knitting needle of the first block is newly rolled down, the block moving direction detection circuit 30 output R acts to apply the down input of the block detection circuit 400, causing the up/down counter to count down. Output BI~B5 as 1
, 0, 0, 0, 0 means one block. In addition, 2
The detailed explanation of the operation of the stages is as above, and further explanation will be omitted. When the switch 702 is activated in the stage detection circuit 70 shown in FIG.
Since it counts down by 3, it is used when the user of the knitting machine makes a knitting mistake and has to reknit several rows.
In the controller 1000 shown in the embodiment shown in FIG. 2, the last knitting needle is locked and cannot be sorted.

This is a consideration when using a sea skiriage, but
Since it has little to do with the present invention, detailed explanation will be omitted.
From the above explanation, it can be seen that there is a one-to-one correspondence between the number of knitting needle 2 and the needle selection information stored in the ROM, but that this correspondence can be shifted by changing the address input in the ROM. Ru.

An embodiment of the present invention will now be described with reference to the circuit diagram shown in FIG. The basic configuration of the needle switch is as described above, so
The configuration of the moving circuit necessary for explaining the needle switch will be explained with reference to FIG. 17. A binary addition circuit 411 is added between the block detection circuit 400 and the ROM 600. One 5-bit input terminal of this adder circuit 411 is connected to the output terminal of a movement register 410 having the same function as the block detection circuit 411. B1, D1, and EI represent the least significant bits (B5, D5, and E5 are the most significant bits), and the 5-bit input terminal of the movement register 410 is K.
It is connected to each switch S1, KS2, KS3, KS4, and KS5. One end of the moving switch 417 is connected to the power supply, and the other end of the switch 417 is connected to the flip-flop 41 along with one end of the resistor 416.
3, and one end of the resistor 416 is connected to ground. 414 is an AND element, one gate of which is connected to the Q terminal of the flip-flop 413, the other gate connected to the output TOP of the voltage reduction start circuit 200, and the output of the AND element 414 is connected to the load LOAD terminal of the block detection circuit 400. connected to.

Also, one gate of the AND element 415 is connected to the Q terminal which is the opposite of Q of the flip-flop 413, and the other gate is connected to the TOP of the output of the voltage reduction start circuit 200, and the AND element 41
The output of 5 is connected to the LOAD terminal of movement register 410 and to the gate of monostable multiplayer 412. The Q terminal of the single transistor 412 is connected to the reset input of the flip-flop 413. A clear terminal of movement register 410 is connected to ground via clear switch 418. Also, tappi 4 shown in Fig. 18
Reference numeral 19 shows the case where the device is used as a pattern output signal extraction tool for pressing the needle switch. Although the addition circuit is one embodiment of the address changing circuit, it is also possible to configure it with a subtraction circuit. Next, the operation of the embodiment shown in FIG. 17 will be explained. First, when there is no movement, in the initial state, the flip-flop 413 is in a reset state, so the AND element 414 is in an action standby state, and the AND element 415 is in an inactive state. It is in.

The data in the movement register 410 is in the state 0, 0, 0, 0, 0 (D=00000) by the clear switch 418. The relationship between the adder circuit output E, the adder circuit input B, and the adder circuit input D is E;B+D, so E=B+00
000=B. Therefore, it is the same as the previous case. The results after needle selection are shown in Table 2. Table 2 In the case of next movement (when using a needle switch), when the movement switch 417 is pressed and released, the flip-flop 413 is placed in the set state, the AND element 414 is inactive, and the AND element 415 is in the waiting state for action.

Next, choose the block number that corresponds to the number of blocks you want to move. If we temporarily decide that the number of blocks to be moved is 2, select one of needle numbers 1 to 8 with the needle of block number 2.If we select needle number 1, the pattern will move as shown in Figure 18. When green needle 2 is pressed with tappi 419, which is a signal extraction tool, switch KS2 is turned on, but switches KS1 and KS3 are turned on.
, KS4 and KS5 are not included. Subsequently, the switch GSI is turned on, and the switches GS2 to GS8 are not turned on. Next, when the TOP obtained by the leading needle detection circuit 100 and the Shoshita detection circuit 2001 acts, the AND element 415 becomes active and gives a signal to the load terminal of the movement register 410 so as to take in the parallel input data of the movement register 410. .

Also, the switches KSI to KS5 of the second block are input. The data at that time is KSI: 0, KS2: 1, KS3:
0, KS4:0, KS5:0, and the movement register 41
When 01 data is taken in (D=00010), the flip-flop 413 is reset by the output of the monostable multiplayer 412, which operates using the trailing edge of the pulse waveform when the AND element 415 is activated as a trigger. Therefore, the AND element 414 is in an operation standby state, and the AND element 414 is in a standby state.
15 has no effect. Also, since the adder circuit output E is E=B+D, B;B+00010. This is RO
It will always give M's address plus 2. For example, when knitting with the carriage 4, if the knitting needles 2 of the first block are held down, B=00001, so E=
000011000010=00011, and the ROM address will point to the third block. Also, when the carriage 4 advances and reaches the second block and presses the knitting needle 2, B = 00010, so E = 00010 100001
0=00100, and the ROM address will point to the fourth block. Table 3 shows the needle selection results when knitting was done in the same manner. Table 3 Comparing Table 2 and Table 3, it can be seen that there is a difference of two blocks.

This amounts to a movement of two blocks. When returning to the case where there is no movement, the clear switch 418 is pressed and the output D of the movement register 410 becomes 00000, making it possible to set the movement amount to zero. If it is desired to change the amount of movement, the same operation as described for movement can be performed, and the amount of movement can be achieved by pressing the knitting needle 2 of the desired block number. Note that the needle switch described above shares the search board, which is one component of the needle selection device, and its position detection switch, and for example, the needle switch may be replaced with another switch. The needle switch can also be used as a switch in other ways. Furthermore, in the above embodiments of the present invention, the switch on the search board was used as a needle switch.
It goes without saying that the switch on the handle plate can be used as a needle switch. As described in detail above, according to the present invention, the pattern movement operation can be performed by pressing the needle on the needle bed, so the operation is simple and can be performed with one touch.

Further, there is no need for an input switch such as a dial or key switch for instructing the amount of movement, and the device can be used more effectively.
