Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a needle selection method for a bran machine that controls the selection of bran needles by reading knitting pattern information recorded on a required recording medium as a digital electrical signal.

Conventionally, as this type of Hōbushi method, for example, Hakama Kaisho 51
As shown in Publication No. 139953, etc., the knitting pattern information recorded on a required recording medium such as a card or tape is scanned by a photoelectric reading means to obtain a digital electrical signal of a predetermined number of bits. is stored in a storage device for the time being, and then sequentially and cyclically read out from the stored digital electric signal in relation to the movement of the carriage, and knitting needles are selected according to the contents of each bit that is read out cyclically. A method is proposed. However, according to the above-mentioned needle selection method, when sequentially and cyclically reading out stored digital electrical signals in connection with the carriage movement, it is necessary to, for example, reverse the left and right direction of the pattern information, or reverse the black and white direction of the pattern information. In accordance with the contents of the needle selection mode setting means, it is necessary to perform complex storage digital signal output control operations such as cyclically changing the bit arrangement order to be read out or expanding or contracting the bit range to be effectively read out. Moreover, it is considered indispensable even when the carriage is running at high speed, and there has been a major problem in the readout processing speed. However, in the present invention, the digital fin air signal obtained by reading the knitting pattern information recorded on a desired recording medium is stored separately from the first storage device that stores the digital fin air signal as bit contents corresponding to each part of the recording medium. Furthermore, there is a second storage device containing bit contents corresponding to each line needle on the needle bed, and the knitting pattern recorded on the storage medium is variously changed to set what kind of knitting pattern is to be realized on the striped material. According to the needle selection mode setting means for the purpose of the present invention, the contents of the first storage device are proposed and stored in the second storage device so that the changes set in advance by the mode setting means are realized, and then the carriage is moved. It is characterized in that the stored contents are outputted to the knitting needles corresponding to each bit of the second storage device in relation to running, and the green needles are selected according to the contents. In this case, the control operation for determining the stored digital electric signals related to the traveling of the carriage is made very simple, and for example, the contents of each bit of the second storage device are not related to the setting contents of the needle selection mode setting means. It is a very simple control that only reads out the corresponding bran needles one by one in a one-to-one relationship, and the reading processing speed can be sufficiently shortened, and it is possible to satisfy even high-speed carriage movement. It provides a needle selection method,
Furthermore, the selection of a knitting machine that is especially suitable for home use allows you to freely obtain your favorite knitting patterns by changing the bran pattern that appears on the knitted fabric in various ways with extremely simple key operations.

~h is the carriage renunciation selection cam mechanism 16 or 16a
In order to perform needle selection control in cooperation with the handle plate, eight handle plates are arranged so as to be movable individually in the direction in which the bran needles are arranged while being overlapped in the front-rear direction.

Anchor-like protrusions 46 for locking rope needles as shown in FIGS. 6 and 9 are individually provided on each of these handle plates 4 strings to h at a pitch of every eighth knitting needle 3. As a whole, they are formed to be different from each other, and in this example, as shown in FIGS. 10 to 12 in particular, the handle plate 45a has fishing protrusions 46 corresponding to the knitting needles 3 of the 10-shaped needle on the left side. Similarly, the handle plate 45b has a fishing protrusion 46 corresponding to the hook 3 on the left side 9, and the handle plates 45c and 4
By repeating the arrangement order held by 5d, 45e, 45h, 45a, 15b, etc., the handle plate 45h has the fishing protrusions 46 corresponding to the knitting needles 3 of 10 rows on the right side. In addition, each of the handle plates 45a to 45h is arranged so that the fishing protrusion 46 does not correspond to the lower part of the bran needle 3 but is arranged between it and the knitting needle 3 adjacent to the left side due to the action of the spring 47 hung on the left end of each handle plate. Although it is held in the working position, by moving it to the right against the action of the spring 47, it can assume a working position in which it can lock the wire needle 3 pushed down.

In FIGS. 3, 5, and 6, 48 is a group of electromagnets, which is a tortoise conversion member, and is a one-needle electromagnet SLO~9, A~F (in hexadecimal), which corresponds to twice the length of the handle plate 45. )
The oscillating plate 50, which is disposed directly above each electromagnet SL, is attached such that its front end is movable up and down with its rear end as a fulcrum. A moving force is given to it in the direction in which it is attracted.

Reference numeral 51 denotes a U-shaped punch arranged in a row so as to correspond to the one-needle electromagnet SL and the shaking plate 50, each of which has a rear leg 51a.
are threaded through the support frame 52 so that they can move up and down, and the front legs 51b are supported so as to be able to swing in a horizontal plane around their respective rear legs 51a. Due to the action of the biasing spring 53, the upper end of the rear leg 51a is attached to the lower surface of the front end of the bridge swing plate 50.

54 is a cam installed above the front leg of U-shaped village 51,
It is connected to the pulley 22 via a bevel gear mechanism 55 so that one rotation of the pulley 22 rotates three times, or in other words, one rotation occurs when the carriage of 16 knitting needles 3 moves.

In the cam theory 54, the lateral operating cams ACO to F, which are fixed to one needle as shown in FIGS. The length of each horizontal cam top surface is determined to be an angular range corresponding to approximately 4 pitches of the knitting needle, and the cam ring 54 is formed in a spiral shape as a whole so as to go around the cam ring 54. Arranged. Further, on the circumferential surface of the cam mechanism 54, one push-down cam BCO to F is formed in a one-to-one relationship with each lateral actuating cam AC, and each having a phase shift of 180 degrees with respect to the same cam AQ. As shown in FIGS. 5 and 9, the shape of the cam surface that bulges out on each circumferential surface gradually swells from around the green base of both legs of the corresponding lateral action cam AC, and is shaped like an abbreviation of a knitting needle. It is determined to have a top surface over an angular range equivalent to two pitches. For convenience,
In FIG. 10 to FIG. 12, in order to clearly indicate the phase of the lateral actuation cam AC and the push-down cam BC, the cam faces are shown in duplicate so that they face the same cam surface. Each pressing cam BC of the cam ring 54
are brought into contact with the upper ends of the front legs 51b of the corresponding U-shaped punches 51, and are lowered by the action of their cam surfaces against the elasticity of the upward biasing springs 53. It is pushed down to the lower position shown, that is, to a position where the upper end of the rear leg 51a is slightly separated from the lower surface of the front end of the rocking plate 50.

For example, if the electromagnet SL is disconnected,
As the cam mechanism 54 continues to rotate, the upward biasing spring 53
In order for the elasticity of to overcome the elasticity of the tension coil spring 49,
Along with the U-shaped punch 51 returning to the upper position shown by the chain line in FIG. 5 along the circumferential surface of the cam BC, the front end of the grand swing plate 50 is floated. At this time, the front leg 51b of the U-shaped punch 51
Cam theory 5 that enters the movement trajectory of the lateral action cam AC and continues
When the front leg 51b is acted upon by the sideways cam surface of the cam AC according to the rotation of the front leg 51b, the front leg 51b swings about the rear leg 51a. However, when the electromagnet SL is energized, in order to effectively hold the oscillating plate 50 in the position shown by the solid line in FIG. 51 cannot return upward and remains in the lowered position. Therefore, even with the subsequent rotation of the cam wheel 54, the front leg 51b of the U-shaped village 51 is
It is located below the lotus trajectory and remains unaffected by the same cam AC. In FIGS. 5 and 6, reference numeral 56 denotes a movable rod that is supported through the support frame 52 so that the intermediate portion thereof corresponds to the front leg 51b of each U-shaped punch 51 and serves as a swinging fulcrum. It is inserted into the working hole 57 of the handle plate 45 so as to transmit the swinging motion to a predetermined part of the handle plate 45 and move the plate 45 from the needle selection non-activating position to the working position against the elasticity of the spring 47. operatively connected.

The number of moving rods 56 is an integral multiple of 8, which is the number of handle plates 45, and is 1.
Since it is determined as a fixed date, the number of movable fins 56 connected to each handle plate 45 is two, and every seventh one of the total number of movable fins 56 is connected to the handle plate 45 in the order of arrangement. Ru. As shown in FIG. 6, the front end of the moving rod 56 that is inserted into the handle plate 45 other than the specified one is inserted into the horizontally long play hole 58 of the plate 45, so that it is not functionally involved. . In this example, two moving rods 56 corresponding to electromagnets SL0 and SL8 are operatively connected to the handle plate 45a, and two moving rods 56 corresponding to electromagnets SL1 and SL9 are operatively connected to the handle plate 45b. The handle plate 45c corresponds to SL2, A.
e corresponds to SL4, C, handle plate 45th is S
The one corresponding to L5, D is SL6, E on handle plate 45g.
Those corresponding to SL7 and F are operatively connected to the handle plate 45h. 3 and 6, when the belt 24 moves integrally with the carriage 13 or 20 connected thereto, for example to the right,
Since the cam mechanism 54 similarly rotates in the direction of arrow E via the pulley 22 that rotates in the direction of arrow 8 in FIG. The action will be applied sequentially to the object located at , and in relation to the movement of the carriage of one striped needle 3, the action will spread to the adjacent objects one by one.

Furthermore, if the carriage moves to the left, the effects will spread from the right side to the left side. Therefore, in response to the vertical displacement of the U-shaped punch 51, which is sequentially selected to apply or not to the lateral action cam AC, by quick-acting control of the electromagnet SL corresponding to each, The needle selection control operation in which the handle plate 45 is left in the needle selection inactive position or moved to the active position is circulated in the same direction and at the same speed as the moving direction of the carriage. Furthermore, as clearly shown in FIG. 9, the knitting needles 3
When the butt 4 is pressed down, the handle plate 45 having a fishing protrusion 46 capable of locking the bat 4 is moved to the operating position by the action of the lateral movement cam AC via the movement lever 56. , the reduction knitting needle 3 is locked to the fish-shaped protrusion 46, the temporary low butt needle is held only while being acted on by the same cam AC, and is released when it passes over the separation cam 19.

Therefore, in order to create these timings accurately,
The carriages 13 and 20 are configured so that they can be interlocked only when the connecting pins 28 and 28a are fixed in the connecting holes 27 of the belt 24, and even if the connecting pins 28 and 28a are loosened in either of the connecting holes 27, the required timing will be maintained. is ensured.
However, since the arrangement pitch of the connecting holes 27 is set to 8 pitches (36 pitches), for example, the knitting needles 3 corresponding to the fishing protrusions 46 of the handle plate 45a are connected to the lowering cam 1 of the carriage.
Even if the handle plate 45a moves to the needle selection action position around the time when it is pushed down by 8 (18a), it is specified whether the plate 45a is moved by the lateral action cam AC0 or 8. In other words, depending on which of the connecting holes 27 the pin is loosened, the horizontal operation cam AC0
, 8, resulting in a 180 degree phase shift.

Therefore, when both the carriage and the belt are newly connected, the output signal of the phase element 32 is effectively utilized. That is, in this example, as shown in FIG. 9, each knitting needle 3 is attached to the connecting pin 28 (28a
) At the point in time when the line needle 3 is approximately 10 pitches ahead of the point in time when the needle reaches the line (as shown in FIG. 9F), the handle plate 45 necessary for selecting each knitting needle 3 is determined in advance. , and start energizing the required electromagnet SL, and end the energization of the electromagnet SL when approximately three pitches of knitting needles 3 have elapsed from the needle selection point F, and in particular, the U-shaped punch 51 is located slightly in front of the top surface of the push-down cam BC, and is set to start energizing the electromagnet SL just before it is lowered to its lowest point. However, when newly connecting the carriage and the belt, etc. Determine which of the two push-down cams BC whose phase is shifted is at a rotational position suitable for starting energization,
This starts energizing the electromagnet SL corresponding to this.

If you want the column of the pixel area 61 of the "10" stage to correspond to the reading position J, the column of the comment column 62 of the "10" stage corresponds to the observation position K.
As shown in , the sheet 59 may be advanced by operating the manual feed dial 73, but the manual feed knob 91 may be used to move the rows of pixel areas 61 of "10" stages to the observation position in advance.

As can be seen, the contact details of the microswitch 122 are input. In Figure 36, SPU is the electromagnet SLO

Various data regarding what numerical values are to be displayed in 1 are provided by the MPU at the required times.

That is, data provided from the MPU is serially output from the transfer SO terminal and passes through two D-type FF1 and FF2 that form the required delay time, and then is sent to the SPU transfer SO terminal.
Is it a clock pulse that is input to the band and is commonly input from the outside to the transfer clock SC terminal of each processor? 3, data of 4 bits of -word is serially transferred for each bit of -pulse. Third

An AND circuit 18 is connected to each clear terminal CL of F3 and FF4.
Since the "H" reset signal is input through 2, the clock pulse 3 is not output. Specifically, the MPU output port 06 is set to "1" and the SPU output port 03 is set to "0". ”, each JK type FF3, FF4 is in a reset state. Therefore, for example, boat 06 is "0" or boat 03 is "1".
When one of the clocks is set, the transfer clock starts up and clock pulse ◇3 is output to the SC terminal of each processor. That is, the transfer clock can be activated from either the MPU or the SPU, and data can be transferred from the MPU to the SPU whenever necessary. In Figure 36, the MPU is followed by an external RAM of 256 words x 4 bits, and the output port R
RAM addresses (AO to A7) are specified using O to R7, and 4-bit data is input/output in parallel using input/output ports R12 to R15.

The output port R8 is used to control the writing and reading of data to the external R-sensor 4. Specifically, the output port R8 is

In addition to a 10B power source obtained from a normal ACIOOV power source through a necessary transformer and a DC stabilization circuit, a battery 183 as an auxiliary power source for memory backup as shown in FIG. 36 is connected to the power terminal of M. , the stored data is retained by preventing the contents of the RAM from volatilizing.

In the address structure of the external RAM shown in FIG. 43, the details of the contents of each register assigned as a working register are as shown in FIG.
The contents of the contacts O to SWIO and the stage feed step of the sheet 59 are stored and effectively used for various control operations described later.

In FIG. 43, the address portions indicated by "'1" to "c" are used to store input data layered in response to the lighting display of the lamps L1 to L12, respectively. The calendar number data corresponding to ``is stored in the address part (3 words) of the first stage m1, and is also stored in the address part (3 words) of the lamp L.
The increase data number corresponding to 2 is stored in the address part of "final stage {2)", and in addition to the counterfeit number data, the left and right data are required. In the address part (4 words), each word is assigned for left and right distinguishing data, and is stored with left L = 0 and right R = 1 bit contents.
The data for clear displaying "0" on the layer number display section 111, that is, the data "000" is always stored, and the sensor 77 detects the sheet 59 in the address part of "Number of layers REG".
The number of stages of the corresponding pixel area 61 is stored. 43rd
In the address structure of the external RAM shown in the figure, each address part of "normal left" and "reverse left" is assigned to the first to fourth storage units in the first storage device, and for example, The "right right" memory, which is the first storage section, stores digital electrical signals obtained when the sensor 77 scans forward toward the right, specifically, its operating circuit 157 (third
The "DATA" signals output from the "DATA" signal output from the second storage section "Reverse Right" Memo Kawako, which is the second storage section, are stored in the output order.
In addition to storing the inverted contents of "0" and "1" of the "ATA" signal, the sensor 77 reverses the traveling direction and performs backward scanning to the left in the "normal left" memory, which is the third storage section. The "DATA" signals obtained when
The content obtained by inverting the "0" and "1" of the signal is stored.

These first to fourth storage units each have a configuration in which one bit corresponds to one pixel area 61, corresponding to the pixel area 61 on the sheet 59 that is sequentially scanned by the reciprocating movement of the sensor 77, In order for the contents of each bit to be specified in the same output order of the "DATA" signal, for example, regardless of whether you are traveling in a round trip, the "DATA" signal that is output first during that travel is
A'' signal is stored in bit address ``0'', then bit address ``1'', bit address ``2'', and so on, and finally stored in bit address ``59''.

Details of this bit address are partially illustrated in FIG. In Figure 43, "20 dishes its"
The address part indicated by is assigned to the second storage device corresponding to each knitting needle 3 on the needle bed 2, and each bit content thereof corresponds to the bran needle 3 in a one-to-one relationship.
A digital electric signal of 1 with knitting needles and 0 with no needle selection is stored, and the bit address corresponding to the leftmost striped needle on the needle bed 2, that is, the knitting needle of "left 10 false flea" is set as "100". From this, the bit address corresponding to the knitting needle of "Left 9 Sakai Flea" adjacent to the right side can be counted in order such as "101", and the bit address corresponding to "Right 10 Chojuichi knitting needle" can be specified as "299". ing.

FIG. 43 partially illustrates the bit address structure of "100 to 299". The data memory RAM (hereinafter referred to as internal RAM) configured inside the MPU has the address configuration shown in FIG.
As clearly shown in the figure.

In the content RAM of the MPU shown in Figure 45, in particular, the "Nd" cash register for OUNT is counted in 16 numbers from "0 to F" corresponding to the number of the electromagnet SL in the above paragraph. "C REG" for carriage COUNT represents the carriage position on the needle bed 2, and "200b" in the external RAM is
It is a soft counter that performs a counting operation of at least "100 to 299" so as to specify the bit address of "its", and specifically counts in a range exceeding "Satoshi to 301". Similarly, “K” for ADDR/COUNT
O, 1" cash register is the first memory bag layer "Front right, 1~
It is a soft counter that performs counting operations from 0 to 59J by specifying a common bit address in the "reverse left" memory, and the "D REG" for transfer stores numerical data to be displayed in calendar numbers. It is effectively used when data is transferred from the MPU to the SPU. On the other hand, SPU
The internal RAM has the address structure shown in Fig. 47, and the details of the contents of each register assigned as a working register are as shown in Fig. 48. In particular, "D REG" for transfer is , stores the data transferred from the MPU, and also displays "〇・REGJ", "D・R
The data obtained by adding so-called sub-erasure processing to the contents of "EG" is stored and used effectively for subsequent display constraints.

Now, the specific control operations of the MPU and SPU consisting of the above-mentioned configurations can be understood from the flow diagrams shown in FIGS. 55 to 74.
The explanation will be made with reference to the address configuration diagrams shown in FIGS. 3 to 47.

First, the control operation of the SPU will be explained according to the flowcharts shown in FIGS. 55 to 59. In the main flow shown in FIG. First, to clear the system, all boats PO to P1 are set to "0".
”, the pulse motor 76 is stabilized in the initial stop excitation state, and the “C・END” signal is set to “
In addition to outputting it as an initial state signal of "L", the boat R
Set all of O~R15 to "0" and electromagnet SLO~
All SLFs are turned off.

Next, the SPU stores "0" as a transfer flag in the data transfer type register ■, and sets "0" to all boats ○'0 to 03.
By setting "0", the display on the calendar number display section 111 disappears, and the boat ○'3 is set to the state before starting the external clock forming circuit 181. Next, SP
After U selects that the serial data transfer is performed in synchronization with the external clock 3, it stores the initial "000" data in "D.REG", as shown in FIG.

“DATA・CHANGE” subroutine (hereinafter referred to as DC
(referred to as a subroutine). The SPU follows the flow diagram of the ○/C subroutine shown in FIG.
When moving the data contents of "D・REG" to "〇・REG", a so-called atmosphere-reducing process is executed, and specifically,
“0” which does not need to be displayed based on the three-digit data
" data is converted to "F" and other data is written as is to "〇・REG". For example, "D・REG"
If the content is "rooo", convert it to "FFO",
If it is "010", convert it to "FIO",
Also, when it is "100", it is written as is to "D'.REG". Therefore, immediately after the above power-on reset, the data of "FFO" is "D'・R
EG”. The SPU is shown in Figure 56.
After executing the C subroutine, follow the flow of “DISPLAY” shown in detail in FIG.
EG'' is displayed in segments on the calendar number display section 111.

Specifically, first store "3" in the register for specifying the display digit, then set the register "〇n" to address "〇2", and call "〇2" based on this. Boat 〇days (〇4-〇7) on the condition that the content of `` is not ``F''.
Immediately after, set "3", which is the contents of the cash register, in the boat 〇L (00 to 〇3). 2
” → Boat ○′1=1, “1” → Boat ○′0=1, “
According to the PLA configuration in which there is no port 0' with 1" → 1 output, the segmented element SE2 of the upper digit is driven,
The contents of "D'2" are displayed by lighting. And the same element S
Let the E2 lighting display continue for about 200 seconds, then make it disappear, then store "2" in the register, set "〇n" so that "〇1" is addressed, and then turn it on again. The contents of "D'1" called out in the same manner as described above are displayed on the segment element SEI by approximately 200 lights.

Next, ■ Store "1" in the register, set "D'n" so that "D'0" is addressed, and then call the contents of "D'0" in the same manner as above. is displayed by lighting on the segment element SEO. If called ``D'0
” to “〇2” is “F”, the corresponding segment element SE is not driven, and nothing is displayed due to so-called extinguishing. In FIG. 55, after performing the "DISPAY" control operation as described above, the SPU checks the contact details of the microswitch 122, which is the input signal of the boat K'1, and
9 is open/closed.
According to the flow of ``SPLAY'', the ``display mode'' is set in which the contents of ``〇・REG'' are continuously displayed on the pupil number display section 111, and while the hatch 119 is in ``Kaiichi'', the above ``DI
By repeating the control operation "SPLAY", three-digit segment display is performed using the dynamic drive system.

If the hatch 119 becomes "closed", the SPU will
ISPLAY” operation is canceled and hatch 119 is restarted.
It enters a "standby mode" where it continues to wait for Kaiichi to become active, and during that "standby mode" it constantly inquires about the open/closed status of the hatch 119, and immediately after the hatch 119 becomes "Kaiichi", the "D.R.
Data ``000'' is stored in ``EG'', and the program returns to ``display mode'' via the DOC subroutine. In Figure 36, when the SPU receives serial data transfer from the MPU, it has a clock counter that counts transfer clock pulses ◇3, and counts a total of 4 clock pulses ◇3 to perform serial transfer of a 4-bit word. When finished,
The process immediately exits from the main flow and shifts to the data transfer interrupt control operation shown in FIG.

The data serially transferred from the M-circle U to the SPU is
As shown in Figure 8, “with needle selection”, “without rhombus needle”,
There are 5 types of display (calendar number) data: sheet forwarding, sheet returning, and ``1'' and ``2'' representing each data.
, "3", "6", and "7" are serially transferred, the SPU immediately executes various control operations based on the data, and then returns to the main flow.

That is, when the SPU receives serial data transfer from the MPU and moves to the interrupt control operation flow shown in FIG. For example, if the transferred data is "1", then the contents of the cash register are rewritten to "1", and then the next time The SPU itself activates the external clock generation circuit 181 and receives data transfer from the MmU.

Specifically, the external clock pulse J3 is output by setting the port 〇3 to “1”, and the prepared “x
" data (electromagnet SL number) is transferred. More specifically, after resetting the serial transfer flag and starting the transfer clock, the clock pulse? Inquire about the transfer flag that is set based on the counter that counts 3, and when you know that a total of 4 clock pulses ◇3 has been output and the transfer has been completed, set port 0'3 to 0. The transfer clock is started and stopped at , and after waiting for the required time, the process returns to the initial interrupt control flow.
Since the content of the previously stored @register is "1", the SPU rewrites it to "0" again, transfers the transferred "x" data to the register, and selects "with needle selection". Since the time is a needle selection type that cuts off the electromagnet SL, ■
The sunrise cassette of the boat R' matching the register contents is not performed, but only the L output setting of the boat R' corresponding to the electromagnet SL to be cut off at that time is performed.

Specifically, as can be understood from the timing of needle selection shown in FIGS. 9 and 10 to 12, the electromagnet SL, which should be energized, is disconnected from the electromagnet SL, which should be energized in relation to the traveling direction of the carriage. Since the electromagnetic left SL is in a positional relationship with a phase difference of 3 pitches, the SPU determines "D" from the contents of the register if it is right based on the carriage running direction obtained by asking the "FWD" signal. A subtraction operation is performed for the la Hayabusa to decrease, and if it is on the left, an addition operation is performed in which "D" is added in the same way, and the boat R to be made into data is set to "0", and then the main flow is returned to. Further, when the data transferred from the MPU is "2", the SPU stores "2" in the register so as to execute the "no needle selection" control operation according to the flow shown in FIG. SPU similar to above
Start the transfer clock from the side, and send "x" from the MPU.
Transfer data.

Since the content of the previously stored @ register is "2", it is rewritten to "0" again, and the transferred "
x" data in the register, set the boat R' that matches the contents to "1", and set it to the corresponding electromagnet S.
The energization of L is started, and then the boat R, which has been determined based on the addition/subtraction operation of the same machine, is set to "0", and then the main flow is returned to. Also, when the data transferred from the MPU is "3", the SPU executes the control operation for "display data" according to the flow shown in FIG.
First, "3" is stored in the @ register, and then the transfer clock is activated from the SPU side, and data "x" is transferred from the MPU. Then, the contents of the ■register stored earlier are “3”.
”, so after rewriting it to “4”, the transferred “x2” data is written to “D2” of “D・REG”, the transfer clock is started from the SPU side again, and the MPU Transfer the data of "xl" from. Next, since the content of @Register that was rewritten earlier is "4", it is rewritten to "5", the transferred "xL data" is also written to "DI", and the same external clock as above is written again. Upon activation, data of "xo" is transferred from the MPU. And, since the contents of the ■register that was rewritten earlier is "5",
After returning this to "0" again, the transferred "xo" data is written to "DO", and then, through the above ○・C subroutine, the contents of "D・REG" are written to "○・REC".
, and return to the main flow. In the transfer of such "display data", "x" which is sequentially transferred from M circle U
The data from ``2'' to ``xo'' is the contents of each digit of ``D.REG'' in the internal RAM of the MPU, and is therefore transferred as is to the numerical data stored in each digit, ``D.REG'' of the SPU. Moreover, since the hatch 119 is in the open position at the time when the "display data" is transferred, the SPU operating from the interrupt flow in FIG. 58 returns to the main flow. The newly transferred data is displayed by lighting on the calendar number display section 111 instead of the segment contents that were being displayed.

Also, when the data transferred from the MPU is "6", the SPU performs "sheet feed" according to the flow shown in Figure 58.
To execute the control operation, first store "4" in the register for the sheet feed timer, and then
Set '2 to 'rl' to start driving the pulse motor 76, and set the 'C/END' signal to the 'H' sheet feed back control state, then start the built-in timer of the SPU'. let

That is, in the step control of the pulse motor 76, the SPU uses a built-in timer to feed each step of the pulse motor 76 with an excitation pulse change at an interval of 10 seconds. It is executed in a continuous feeding operation, and specifically, after changing the "0" and "1" of the required boats P'0 and P1, the timer is set to low seconds and started, and then Return to the main flow. Then, when the timer counts low seconds and the so-called timer over (end) flag is set, the SPU immediately exits the main flow and starts controlling the "timer end interrupt" shown in FIG. Transition. For example, after the initial timer starts for "Sheet Feed" above, the contents of the ■ register stored earlier are "4", so according to the interrupt flow in the same figure, the register contents of ■ are rewritten to "5J". Later,
Set the boat PO to "1", start the timer again, and return to the main flow. After that, when the timer over flag is set again after 10 seconds, the flow returns to the interrupt flow shown in Figure 59, and after rewriting the content to "6" based on the register's content "5", , boat P1 as “
0", start the timer, and return to the main flow. Next, when moving to the interrupt flow shown in Figure 59 with the same operation as above, ■ After rewriting the contents of the register to "7", set the boat PO to "0" and start the timer. Return to the main flow. Then, in the subsequent interrupt flow control, "C・E" indicating that the one-step feeding operation of the sheet 59 is completed
In order to output the “ND” signal to “L”, the boat P′2 is
0" and discontinues use of the built-in timer to stop its timekeeping operation, and then returns to the main flow. FIG. 42a shows the boats P'0, P'1 obtained by the above-mentioned "sheet feeding" and the excitation pulse changes of the pulse motor 76 which are the output changes of each inversion signal, and the sheet feeding of the pulse motor 76. Based on the mechanism, the sheet 59 is fed by one step in the direction of arrow G in FIG. 5 after a total of 4 steps of 40 seconds, each step being 10 seconds.

Furthermore, although the "C.END" signal is not effectively used for normal one-step feeding operation, for example, the sheet 59 can be continuously returned to multiple stages based on the command from MmU.
In the case of feeding in the direction of arrow G in FIG. 5), the MPU asks the user to proceed to the next feeding operation each time one stage of feeding operation is completed. If the data transferred by the SPU from the MPU is 7J, first store ■register ``1'' to execute the control operation of ``sheet return'' according to the flow shown in Figure 58. Later, the boat Po, P'
2 is set to ``1'', the pulse motor 76 is driven back, and after that, a timer similar to the above is started, the main flow is started, and then the main flow is returned.

Then, according to the "timer end interrupt" flow shown in FIG. 59, the SPU changes the contents of the register to "
2'', 3re changed to ``7'', and boats P'0, P
The operation of setting 1 in the required order and starting the timer is repeated to form the excitation pulse change shown in FIG. 42b. Therefore, in the case of "sheet return" mentioned above,
After a total of 4 steps of 40 seconds (i.e., step 10 seconds) have elapsed, the sheet 59 is returned by one step in the direction opposite to the arrow G in FIG. 5, and so-called sheet return is executed. and,
In accordance with the "timer end interrupt" flow shown in FIG. Stop using it and then return to the main flow.

Next, the control operation of the MPU will be explained according to the flowcharts shown in FIGS. 60 to 74. First, in FIG. Control is started after a time delay, and the system is cleared at the beginning using the key m (described later).
Store "D" in @Register (different from SPU's @Register, same for other registers) that represents the step order of By clearing the memory data to "000" and setting the boat 07 to "0", the DC motor 86 for driving the sensor is initially stopped, and the carriage reversal flag register and sensor reading flag are also cleared. The initial set flag signal "0" is stored in each register, and the above serial data transfer is also selected to be executed on the MPU side in synchronization with 3 using an external clock pulse. Furthermore, since the MPU has a configuration in which each output port is automatically set to "1" by a power-on reset, there is no need to specifically set port 06 by a program command, and the initial stage before starting the external clock generation circuit 181 is not necessary. The state can be confirmed. Next, MPU
After masking the external interrupt based on the above "IRQ" signal, specifically, "L" which is valid as an interrupt signal.
Even if the "IRQ" signal of "IRQ" is output, it does not immediately shift to external interrupt control operation in response to this, but only the existence of that interrupt signal is stored as an interrupt flag, and then the flag is set by a program instruction. When testing, after masking the state in which interrupt control can be executed based on the flag, inquire through the boat K2 whether the hatch 119 is open or closed, and, for example, if it is open, select the data input mode. Therefore, "KEY・SCAN・B" shown in detail in Figure 61
control operations such as key scanning are executed according to the flow of "K.S. Let's do it. When the MP input mode is set to ``data input mode,'' first select ``K'' as shown in Figure 61.
・According to the ``S・B'' flow, the contents of the ``register'' are rewritten to ``0'' as initial data for opening the hatch, and ``B'' is stored in the ``register'' for the key input permission flag.

That is, as shown in FIG.
``2'' has a weight of ``4'' and ``8'' depending on the content of each bit, ■0 bit with a weight of ``1'' is ``0'' to ``9''
The bit 1 with a weight of 2 corresponds to the numeric key 110, and the bit 1 with a weight of 4J corresponds to the left and right keys 114 and 115.
■3 bit with a weight of 8 is the stage setting key 116
, and the starting key 117, respectively, are stored with flag contents indicating that key input is permitted when each bit is ``1'' and that key input is prohibited when each bit is ``0''. And M
Each time each of the above keys is operated, the PU asks for the contents of the key input permission flag ■register, and if the key input is permitted, the key operation at that time is validated and control is performed based on this, and if the key input is not permitted, it is invalidated. The correction key 112 always responds as a valid key operation regardless of the contents of the cash register. Therefore, the above “K”
・In the “S・8” flow, ■ “8” stored in the cash register
The data assumes that only the left and right keys 114 and 115 are invalid,
Make other keys valid input states.

After that, the MPU lights up the lamp LO that matches the previously stored ■register contents "0", specifically, the boat PO~
Output and latch "0" to P3 to clearly indicate when to operate the pattern selection switch SWO at the beginning of the hatch opening, and also set "0" as the counterfeit number flag on the cash register.
After that, write the data “000” to “0・REG”, and then write the contents of “D・REG” to SPU.
Serial transfer to. In order for the MPU to transfer SPU data, it is sufficient to set the port 06 to "0" and activate the external clock forming circuit 131, and the counter that counts the transfer clock pulses ◇ 3 counts 4 pulses ◇ 3. Immediately after the data transfer of the 4-bit word is completed, the port 06 is returned to "1" and the transfer clock activation is stopped. Moreover, when transferring the contents of the above "D REG", since it is a transfer of "display data", MenU first transfers "3" for the data type, and then,
In preparation for starting the transfer clock from the SPU,
” so that the “D2” data is output from the Sq terminal, and after that serial transfer, the “DI” data is transferred, and after that transfer, the “DO” data is transferred. Set to . After the MPU executes the initial hatch opening control operation according to the "K・S・B" flow shown in FIG. 0", all keys are scanned simultaneously, and it is checked whether the key contact contents inputted from KO to K3 via gate group GI are all OFF, and the inquiry is repeated until this is satisfied. And if you are satisfied with this,
Next, the open/close state of the hatch 119 is inquired, and if it is "closed", it immediately shifts from "data input mode J" to "composition mode"; If the interrupt flag is set, that is, if the external interrupt signal IRQ signal is present, the 74th interrupt flag is tested.
Shifting to the external interrupt flow shown in the figure, necessary various control operations are executed. After executing the external interrupt control shown in FIG. 74 based on the test result of the MP peak interrupt flag, or if the interrupt flag is not set, then the "MOY○・SW” (hereinafter referred to as M・S
The system inquires about the support contents of various SWs according to the flow (referred to as ), and stores the ON/OFF data in the required registers of the external RAM.

That is, first, input the contact details of the pattern selection SWO, and
In case of “All moyo”, data of “3”, in case of “2 moyo”, data of “2”, and in case of “1 moyo”, data of “1”
The data of ■ is stored in the cash register, and the following @1, ■, ■, ■2, ■3, ■1, ■ prepared corresponding to each SWI to SW9 are stored according to the flow shown in Fig. 67. 2
, @1 are stored in each register. In particular, when the contact content of double amikomi SW7 is ON, the data of "1" is sent to the ■register, and the data of "1" is sent to the @2 register, regardless of the contents of the forward/reverse solder SW6, forward/reverse solder, and SW2. Store data of “0”. Next, the MPU asks whether a key is being operated according to the main flow shown in FIG.
Specifically, set the boat RO to "0" and first press the number keys 110 of "0", "4", "8" and the left key 11.
4 scans at the same time and all keys are OFF
If it is, that is, if there is no key operation, return to the flow of asking the hatch status before the interrupt plug test, and execute the same controls as above. , this time change the boat RO' and change the RI to '0'.
”.

Then, simultaneously scan the numeric keys 110 and right key 115 for ``1'', ``5'', and ``9'', and these are also OF
If it is F, repeat the same control as above again, and then
Set the boat R2 to "0" and press the number keys 110 of "2" and "6", the row alignment key 116, and the correction key 112.
are scanned at the same time, and if they are all OFF, at the next scan time, boat R3 is set to "0".
Numerical keys 110 for "3" and "7" and starting key 11
7. Scan the step keys 113 at the same time. If all of these are also OFF, the key scan control corresponding to the first boat R is returned again and repeated scans are performed according to the same steps. In each of the above key scans, if at least one of the four keys is not OFF, that is, if it detects that a key operation has been performed, the MPU performs the "KEY・S" shown in FIG. 62.
CAN-1 (hereinafter referred to as K-S-1), and the scan boat number at that time, boat RO~
■ Store any “0” set number of R3 in the cash register,
For example, if key operation input is confirmed during scanning when boat R2 is set to "0", data "2" is stored in the register.

Next, it is determined which of the four keys was operated, and if it is the key connected to the boats KO, K1, and K2, then the "K" key shown in FIG.
The process moves to ■, ■, and ◎ in the "EY・SCAN・2" flow, but if it is not a single key operation, such as when two keys connected to boats KO and KI are operated at the same time. In this case, the process moves to the point ◎ in the "K・S・B" flow shown in FIG. 61 and asks again whether all the keys are turned off, and the inquiry is repeated until this is satisfied.
That is, when the MPU confirms the key operation through the key scan, it executes the necessary control based on this, and then always asks whether the key is turned off.In other words, it asks whether the key is turned off, and then Only if you satisfy
Performs an operation to move on to the next control, disabling key operations when two keys are operated at the same time, or
This prevents the same scanning operation from being repeated more than once due to continuous operation of one key.

In the “K・S・2” flow shown in Fig. 63, ■
M Maruyama moves to the point and proceeds with the control operation. Based on the above key scan operation, press the number keys 1 from "0" to "3".
In relation to the case where one of the 10 keys is operated, first ask the contents of ■bit 0 of the cash register, check whether input of the numeric key 110 is permitted, and if this is satisfied, press " Ask whether the data of the most significant digit of "D・REG" is "0". In other words, check whether three-digit calendar number data has already been entered in "D.REG", and if it has not been entered yet, then check whether the contents of "D.REO" are "000". , otherwise, or if the new key input data is not "0" even if it is "000",
The contents of "D.REG" are shifted one digit at a time toward the higher digits, and new key input data for the customer at the cash register is written in the lowest digit. Then, ■ store "1" in the cash register as flag data indicating that there is a calendar number, and ■ change the contents of the cash register to a state where the input of the step key 113 is permitted, and then

Next, after returning the contents of the register to "0" with no number of layers, clearing "D.REG" and transferring to the SPU, it starts asking for key OFF again. According to the "KEY・SCAN・2" flow shown in FIG. 63, when the MPU confirms that the operation of the row alignment key 116 is valid, ■ If the contents of the register include a number, the "number of rows REG" at that time. Recall the contents of “D・REG
”, transfer to SPU, and clear “D REG”, then start asking for key OFF again. ■If the contents of the cash register are "1" with a calendar number, change it to "0".
After returning to no calendar number, sheet feeding or bunching control is executed until the contents of "D.REG" which stores the calendar number data at that time match the contents. For example, “D.
When the content of "REG" is larger than the content of "number of stages REG", "sheet feed" is represented to the SPU. The data of "6" is transferred, and each time the data is transferred, the contents of the "stage number FEGJ" are added by "11".
Every time the stage feeding operation of the sheet 59 is completed by referring to the "END" signal, the data for the next "sheet feeding" is transferred until it matches the contents of "D REG" of "number of stages REG". Repeat. In addition, when the contents of ``rD・REG'' are 4 points lower than the contents of ``number of rows REG'', the data of ``7'' representing ``sheet return one'' is transferred to the SPU, and for each transfer. Control is performed to subtract the contents of the "number of rows REG" by "11", and each time the step return operation of the sheet 59 is completed by referring to the "C END" signal, the data of the next "sheet return 1" is ``Number of stages REG''
Repeat until the contents of ``D.REG'' match the contents of ``D.REG''. After the required data transfer is completed, “D.R.

If the operation in step 17 is confirmed to be valid, if ■ the contents of the cash register include a calendar number, it will not respond to the start key 117 at that time and will start asking for the key OFF again; If it is ``0'' without a number, the contents of all memories of ``correct right'', ``correct left'', and ``reverse right'', which are the first memory diamonds of external agent port AM, are set to ``0''. After clearing and clearing the second memory layer "20 dishes its" memory, "D.R.

The MPU executes the skin operation as described above according to the "K.S.B" or "KEY.SCAN.1 to 4J flows" shown in FIGS. 61 to 65.
In response to the operation No. 13, the contents of the step order register ■ are incremented by 1 for each operation, and the required lamps LO to L13 are turned on to match the contents of the register. Specify the data location that should be counted, but in particular, change the flag contents of the cash register according to the step order of the @register customer.

In other words, the contents of @Register are "5ha" 6ha "7ha" Aha "B"
C When the number key is "C", the numeric key 110 will only function effectively after the left and right keys 114 and 115 are operated, and after the left and right keys 114 and 115 are operated, the numeric key 110 will only function effectively after the left and right keys 114 and 115 are operated. However, the step key 113 is prevented from functioning effectively. In addition, the left and right keys 114, 1 1
Regarding 5, ■The contents of the cash register are "5", "6ha", "Aha"
B is "C", and ■ there is no Taoism at the cash register "0"
It functions effectively only when is stored, and the combination key 116 and the start key 117 function effectively only when the number of customers at the register is "0" or "D". There is. 61 to 65.

The key input control executed by the MPU according to 1 will be explained with reference to FIG. 19. First, as the hatch 119 is opened, the lamp LO is lit and "0" is displayed on the calendar number display section 111. In this "0" step state, the calendar number is entered using the numerical keys 110, and the calendar number display section 11
The input data displayed at 1 is effectively used as stack alignment data, and in response to the subsequent operation of the stack alignment key 116, the alignment control as described above is executed. In addition, when a value other than "0" is displayed on the layer number display section 111 in the "0" step, there is no change in the display even if the step key 113 is operated, and the electronic buzzer BS also None is determined to be an invalid key operation. In order to enable the step key 113 in this state, it is sufficient to operate the correction key 112, and thereby the calendar number display is cleared to "0", resulting in a "0" step state with no calendar number. In the "0" step state with no calendar number, in response to the operation of the start key 117, the start control as described above is executed. In the "0" step state with a calendar number, the start key 117 does not function effectively. As for whether or not it has functioned effectively, the electronic buzzer BS notifies you each time it functions for a fixed period of time, for example by making a beep sound. In addition, when the step key 113 is operated in the "0" step state without a digit, the state becomes "1" step state, the lamp LI lights up, and the data input corresponding to the first stage of "Moyo 1" is called. The data stored in the first stage memory of the external RAM is recalled and displayed on the calendar number display section 111.
When desired starting stage data is input from this, the input data changes with each key operation and is displayed on the layer number display section 111,
And it becomes a "1" step state with Taoism. left/right key 1
14 and 115 have no function. If you make a mistake in operating the number keys 110, the display on the layer number display section 111 is cleared to "0" by operating the correction key 112, and the display enters a "1" step state with no calendar number. From step status "1" to "D", pitch alignment key 116, pitch start key 1
17 are disabled, and even if you operate these keys, they will not function at all. When the step key 113 is operated in the "1" step state with a calendar number, the calendar number display section 111 at that time
The data displayed in is written to the "first stage {1}" memory, which is the corresponding data end memory.

Then, when "first stage '1' is written to one memory,
The same data is also written in the "number of stages REG", the lamp L2 lights up at the same time, the data stored in the "last stage ■" memory is displayed on the number of layers display section 111, and "2" with no number of layers is displayed.
It becomes a step state. If the error lamp L14 lights up when the step key 113 is operated, it is determined that the calendar number data displayed on the pupil number display section 111 at that time is excessive, and the error lamp L14
When is lit, only the correction key 112 is enabled, and the other keys do not function at all. Therefore, the correction key 112 has no choice but to be operated, and in response, the numeric keys 110 and step keys 113 are enabled, and the pupil number display section 1
1 is cleared to "0", the step returns to the step state without a numeral, and new pupil number data can be input. "2"
In the step state, use the same operation as above to press number key 1.
After the layer number data is input in step 10, press step key 11.
3 is operated, the input data is written to the final stage [2' memory, then the lamp L3 lights up, and the data stored in the "Mosho 1" memory is displayed on the calendar number display section 11. ,
It becomes a "3" step state without calendar number. In response to this,
Similarly, number key 110 is operated, and step key 1 is also operated.
13 is operated, the input data is written to the ``model left IJ memo kawako'', then the lamp L4 lights up, and the stored data in the ``model right 1'' memory is displayed on the number display section 111. ,
It becomes a "4" step state with no number of layers. When the numeric keys 110 and step keys 113 are operated again in the same procedure, the input data is written into the "MakuR1" memory. After that, the step status changes depending on which position the pattern selection switch SWO is set to.For example, in the case of "Zenmoyo", the lamp L7 is lit, and furthermore, the lamp L17 is lit. left and right keys 114,
115 is called, the data stored in the "Basic 1 [7]" memory is called, either the left or right lamp L15 or L16 corresponding to the content is lit, and a numerical value is displayed on the calendar number display section 111. The data (needle number) is displayed,
It will be in the "7" step state of the previous calendar number. At this time, since the data corresponding to the lamp L7 includes left and right discrimination data, the numeric keys 110 are temporarily disabled. Therefore, first press the left and right keys 114, 115 after blocking the new data to be input, that is, the pattern reference position data.
For example, if the left lamp L15 is lit and the left key 114 is operated, the light will remain as it is, and if the right key 115 is operated, the light will change to the left lamp L15. The right lamp L16 is turned on.

At this time, since the numeric key 110 is necessarily operated subsequently, the step key 113 and the left and right keys 114 and 115 are temporarily disabled. Therefore, when desired needle number data is then input using the numeric keys 110 and the step key 113 is operated thereafter, new left/right discrimination data and needle number data are written into the "base 1" memory.

If you make a mistake in operating the left and right keys 114 and 115, use the correction key 112 to correct the left and right keys 114 and 115.
will be valid, so you can freely redo it. Since the operation of the step key 113 is the last input to be counted as "all", the OK lamp L14 lights up to notify this, and furthermore, the number of layers display section 1
11 is displayed, and the state becomes a "D" step state with no calendar number. At this time, the row adjustment key 116 and the row start key 117 become effective again. LAlso, in the step state of "4" where the lamp L4 is lit and a value other than "0" is displayed on the number display section 111, the pattern selection switch SWO is set to "1". Then, when the step key 113 is operated, the lamp L5 lights up, a call display similar to the above is made based on the contents of the "SELECT 1" memory, and the step state of "5" is entered.

Therefore, if either the left or right keys 114, 115 or the numeric key 110 are operated based on the data of the needle selection range to be newly inputted, and then the step key 113 is operated, the current dial will be changed. The data (needle number) displayed on the display section 111 and the data for distinguishing between left and right by lighting the lamp are written in the memo ``Select 1'', then the lamp L6 is lit, and ``Selection 1 [6]'' is written. The contents of one memory are recalled and displayed.Hereafter, in the same manner as above, when the step key 113 is operated after inputting the required data based on the call display in which the lamp L7 is lit, OK is displayed in response.
The lamp L13 lights up, and the end of the data input to be counted is announced as "1 month".

In addition, when the lamp L7 is lit and the step key 113 for memory writing is operated, "2" is displayed.
When it is in the set state, the lamp L8 lights up for data input of "Moyo 2", and "Moyo 2'" is set.
8} - The contents of one memory are recalled and displayed. Therefore, after the same operation as described above is repeated and the required data is input, finally, when the step key 113 for memory writing is operated based on the call display in which the lamp L12 lights up, a response is received. OK lamp L13 lights up and “2
The end of the data input to be entered is announced as "Momo". Then, when the step key 113 is further operated in the step state "D" in which the OK lamp L13 is lit and "000" is displayed on the calendar number display section 111, the OK lamp L13 is turned off and The lamp LO lights up again, and it is "0", same as when the hatch was opened.
Return to the step state.

Sometimes, when the corresponding lamps LI to L12 are lit in each step state and memory data is recalled and displayed, the calendar number operation for inputting new data is not performed, and the step state without calendar number is Mamade step key 1
When 13 is operated, the process immediately advances to the next step state. Therefore, by continuously operating the step keys 113, the inner customers of each data memory, ``first stage m''~
You can call up the required data of Group 2 [C}J and check it at any time.Moreover, if you want to change some data during the call and display, you can change the step status of the required data display. It is also possible to partially change the data by inputting new data and operating the step key 113.The MPU, which operates according to the main flow in FIG. , enters "data input mode" and executes the key scan control etc., but at times hatch 1
19 is closed, if not, continue in the "data entry mode", if so, i.e., if the hatch 119 is closed, exit the "data entry mode". Shift to "organization mode".

After first unmasking external interrupts, specifically, when the above-mentioned "IRQ" signal is output, it is set to a state where it can immediately shift to the interrupt flow shown in FIG. 74, and After performing the flag test, ask the contact details of the stop switch SWIO, and if it is ON,
The state of the hatch 119 is then inquired again by returning to the interrupt mask state. Therefore, as long as the hatch 119 is in the open position and the stop switch SWIO is OFF, the MPU performs control that merely repeats the masking and cancellation of external interrupts and the flag test. When the switch SWI O is OFF, the contents of the carriage reversal flag ■register are asked, and this is "1".
”, rewrite the contents of the ■register to “2”, move to the “60-20 rib” flow shown in FIG. 71, execute the required memory transfer operation, and For the sensor argument flag ■Ask the contents of the cash register and this is "1"
On the condition that The process moves to the flow shown in FIG. 1, performs the necessary control operations, and then returns to the interrupt mask processing again to repeat the same operations as described above.

When the MPU operates according to the external interrupt flow shown in FIG. 74, when the carriage passes near the center of the needle bed, the MPU rewrites the contents of the register to "1", and immediately after that, writes the contents of the register to "1".
At the same time, when the carriage passes near the center of the needle bed, the contents of the register are rewritten to "0", and then the carriage changes the direction of travel. When it is reversed, (2) if the register contents are "0", it is rewritten to "1", and immediately after that, the "60-200 bits" control is executed.

In other words, even if the carriage is finely run and reversed near the left and right sides of the needle bed without passing near the approximate center of the needle bed, the "60-200 bits" control is not repeated each time. .

First, the control operation of the MPU will be explained according to the "Sensor Kendori" flow shown in FIG. There are 1 and 3 registers, which use bits 1 and 3, respectively. 172 drives the DC motor 86 (see FIG. 39), thereby starting the sensor 77 in the right direction.

Then, the first memory device is ``Sho Right'', ``Sho Left Ha'', and ``Gyaku Right''.
, store "0" in advance in the "KO, 1" register for specifying the bit address common to each memory of "reverse left", that is, set it so that the bit address "0" is specified. Then, "1" is stored in the 1 register for the reading confirmation flag, and then it is asked whether the "CLOCK" signal output from the sensor operating circuit 157 (see FIG. 34) is "L". As is clear from FIG. 35a), immediately after the sensor 77 starts to move forward to the right, the sensor 77 moves until it reaches the left end of the first transparent window 70a corresponding to the pixel area 61 of "1". , a “CLOCK” signal of “H” is output, so M
The PU repeatedly asks whether the "CreOCK" signal is "L" until the sensor 77 approaches the transparent window 70a numbered "1". If so, based on the fact that scanning of the pixel area 61 of 1 has started through the transparent window 70a of 1, After rewriting, it is then asked whether the "CLOCK" signal is "H". As a result, when the scanning of the pixel area 61 of "1" is completed, the MPU selects "CLO" of "H".
Immediately after the "CK" signal is output, call in the "DATA" signal, write the "0""1" signal to the ◎ register, set the external interrupt to the masked state, and then write the previously stored ■0
Since the contents of the cash register are "0", ◎The pixel area data of "1", which is the customer inside the cash register, is set to the bit address "0" of the "right right" memory specified by the "KO, 1" cash register. Writing, for example, ◎The contents of the cash register are "" without a knitting pattern.
0” data, write the same “0” data to the bit address “0” of the “right right” memory, and write the data with the “0” and “1” inverted against the contents of the @ register.
Write to bit address ``0'' of the ``reverse right'' memory. Next, the MPU cancels the mask of external damage 9 and performs a flag test, then rewrites the contents of the "KO, 1" register to "2" by calculating "1", and again writes "■1" to the register. 1" is stored. Then, by repeating the same operation as above, when the "CLOCK" signal changes from "H" to "L" and then from "L" to "H", the "DATA" signal at that time is and write to the customer “
2 Write the first pixel area data to the bit address "1" of the "normal right" memory specified by the "KO, 1" register, and invert the "0" and "1" data to the "forward/reverse one". Write to bit address “1” in memory.

The MPU is based on the “CLOCK” signal as described above.
Repeat the "DATA" write operation and write "1" to "60".
"Right right" and "Reverse right" until you get to the first pixel area data.
Each bit address "0" to "59" of the memory is stored in order, but according to the flow of FIG.
” When the contents of the register become “45”, that is, sensor 7
7 "When scanning around the first pixel area 61 of 45,
By setting boat 07 to "0", DC motor 8
6 is stopped, and after that, due to the inertia of rightward movement, the sensor 77 causes the sensor 77 to move moderately to a position on the right beyond the first pixel area 61 of 60.

Then, when the contents of the ``KO, IJ'' register become ``60,'' that is, the sensor 77 is activated by the tension coil spring 80.
When the elastic force causes the vehicle to reverse to the left and begin to travel in the opposite direction, the contents of the previously stored ■0 register are "0".
Therefore, this is rewritten to "1", which is the left direction data, and the flow shifts to setting the contents of the "KO, 1" register to "0" again. According to the flow in FIG. 68, the M circle U is
TA'' signal and data write operation to the memory are executed, but in relation to the backward scanning of the sensor 77 to the left, since the content of the 0 register is ``1'', for example, the 35th As shown in Fig. ”, the inverted data of “1” is written to the “reverse left” memory address “0”. Then, write the 59th pixel area data that will be output next to the bit address ``1'' of the ``positive left'' memory, and
" is written in the bit address "1" of the "reverse left" memory, and similar memory write operations are performed in order. Finally, the first pixel area data "1" is written as "KO,1". ” “Front left” specified by the cash register
Write to memory bit address “59” and
0" and "1" are inverted and written to bit address "59" of the "reverse left" memory. After that, the MPU says “KO
, 1'' register becomes r60'', and ``1'' is stored in ■0 register, so after finishing the ``sensor reading'' control, the ``sheet feeding/returning first step'' shown in Fig. 70 is performed. When the "CLOCK" signal changes from "L" to "L", the MPU moves to control.
Until it rises to "H" and falls from "H" to "L" again, that is, until the reset pulse RP is output,
It is necessary to call the "DATA" signal and write the required memo file, and then repeat "CLO" according to the flow shown in Figure 68.
It is good if it is possible to continue asking whether the ``CK'' signal is ``H'', but for example, when the ``IRQ'' signal is output during the asking operation and the process moves to the external interrupt flow shown in Figure 74. is the “L” to “H” of the “CLOCK” signal.
There is a risk of overlooking changes.

In order to prevent this, when M-yen U operates according to the external interrupt flow shown in Fig. 74, it controls the flow shown in Fig. 69, which is inserted here and there in the flow, and performs the above ◎1 register. Use it effectively. That is, according to the flow shown in FIG. 69, the MPU
”, and only if “0” is stored in ■1 register, the current “D
ATA” signal, write in the ■register, and then ■
1 register is rewritten to "1", so that even if the flow shifts to external interrupt control in the flow in Figure 74 in the middle of the flow in Figure 68, the "L" of the "CLOCK" signal ” to “H” without overlooking the rise, the “DATA” signal can be reliably read and written to the register, and the required “0” and “1” data can be stored in the 1 register. By asking this question, we avoid executing call control more than necessary.

Next, we will explain the control operation of the MPU according to the flow of "sheet feeding and returning" shown in FIG. 70. First, external interrupts are set to the masked state, If "0" without double or double loading is stored, "1" is stored in the ■2 register for intermittent feed step, and then "stage number REG" and "first stage {1} 1 memory contents are equal" 3.
Store the forward feed data of "0" in the register and enter the "Number of stages REG"
Add "1" to the inner leaf of and then "feed sheet" to SPU.
After transferring the data of "6" representing "6", causing the sheet 59 to advance one step, and making the electronic buzzer BS sound, the external interrupt mask is released, and a flag test is performed. "Complete sheet feed/return control.

In addition, if the contents of "Number of stages REG" and "Female stage '1' 1 memory are not equal, then check whether the contents of "Number of stages REG" and "Final stage (2') 1 memory are equal or not. 'Yo, ask the contents of the @1 register, and on the condition that the repeating data '1' is stored in it, set the 'number of stages R'.
Add “1” to the contents of “EG” and send “sheet feed” to SPU
After transmitting the "6" data and hearing the sound of the electronic buzzer BS,
The control is completed by canceling the interrupt mask and performing a flag test.

However, if the contents of the "stage number REG" and the "final stage [2'1 memory" are equal, the content of the "stage number REG" is subtracted by "1" on the condition that the content of @1 is "1" for repetition. death,
Then, data ``7'' representing ``sheet return 1'' is transferred to the SPU.

Then, after making the electronic buzzer BS sound, the interrupt mask is released and a flag test is performed, and then "C.E.
When the SPU confirms that the sheet 59 has been returned by one level by referring to the "ND" signal, it sets the external interrupt to the masked state again and returns the "number of stages REG" after the above subtraction.
Provided that the contents of the sheet 59 still do not match the contents of the "first row [11"] memory, the same control such as subtraction of the "number of rows REG" as described above is repeated until the contents of the sheet 59 match. Execute step return control. Then, after the contents of the "stage number REG" match the contents of the "first stage {1'" memory, interrupt masking is canceled and a flag test is performed.
Complete control. In addition, the contents of "Number of stages REG" do not match the contents of either "Start stage [1'1" or "Last stage (2)1] memory. Moreover, vertically facing "0" data is stored in the @1 register. If the content of the previous ◎3 register is "0" which is the forward feed data, then
” and “sheet feed” data transfer to the SPU.

However, including when the contents of the "number of stages REG" match the contents of the "last stage '21" memory and "1" is stored in the @3 register, the contents of the "number of stages REG" match the contents of the "starting stage '21" memory. Step [1}
70 until "0" is stored in the @3 register again in accordance with the contents of the first memory. According to 1, "Number of stages RE
By subtracting ``1'' from the contents of ``G'' and transmitting ``7'' data representing ``sheet return'' to the SPU, sheet 5 is
9, the electronic buzzer BS is sounded, and then the interrupt mask is canceled and a flag test is performed to complete the control. At times, according to the flow shown in Figure 70, the MPU ■If the register stores data ``1'' with vertical and double additions,■2 asks for the contents of the register and if it is ``1''. For example, by simply rewriting this to "2", the control is finished without performing step forwarding or step reversing of the sheet 59, and "2" is written to the 2 register.
This is set to ``1'' only if the data of
After rewriting, the flow shifts to the sheet feeding or returning control flow as described above.

Therefore, even if the MPU has a chance to execute the control shown in the flowchart of FIG. 70, it moves the sheet 59 forward or backward every other time. The contents of the "row number REG" correspond to the number of steps of the pixel area 61 on the sheet 59 that the sensor 77 corresponds to at that time, and the "carrier 1" thread passes approximately in the middle of the needle bed. The control shown in the flow shown in FIG. 70 is performed each time. Therefore, for example, as shown in FIG. 51, SW8 (see FIG. 19) is set to ``repetition 1'' in the non-depressed state, and ``initial stage {IL'' and ``last stage '2'' are stored in each memory. 1" and "30", the M-circle U operating according to the flowchart in FIG. 70 changes the number of pixel area stages on the sheet 59 corresponding to the sensor 77 to " 1” stage, “2” stage, “3”
The sheet 59 is advanced in stages so as to change the stages, and after the "30" stage, the sheet 59 is continuously returned to the "11" stage, and then the "2" stage. ,
3. Control so that it repeats one step at a time.However, if it is set to ``Vertical facing'', use the same method as above to ``
After proceeding to the 1st stage, the 2nd stage, the 3rd stage, etc.
After the "30" stage, the sheet 59 is moved back one stage and the "2"
9 to 1 step, then ``28'' step, ``27'' step...
After returning to the "1" stage again, move on to the "2" stage, then the "3" stage.
Control so that it repeats one step at a time. In addition, when SW6 is set to ``Vertical double 1'' or SW7 is set to ``Double depth 1'', each of the above-mentioned stages changes by one stage every two times the carriage runs, and the number of stages changes each time the carriage moves once. In relation to the running of, for example, "1" stage, "1" stage, "2" stage,
As a result, each row of pixel areas 61 is moved twice by the sensor 77.

Next, the control operation of the MPU will be explained according to the "60→200 bits" flow shown in FIG.
■If the register stores "3" data indicating "all", first set the external interrupt to the masked state, and then input the initial "0" data to the write step @2 register. Then, in the register for selecting and specifying each memory address AO to 3 of "normal right", "reverse right", and "reverse left" which is the first memory device, "normal right" memory is stored. After storing the data of "8" that can specify "8", the second storage device "
20 plates' memory is cleared to '0' across all bit addresses. ■ On the condition that "1" of "double amikomi" data is not stored in the register, "0" is written in the @0 register for the step for double amikomi.
After the contents of the register 2 are written to ``2'', the data memory transfer operation begins. In other words, in the case of "Zen moyo", the contents of the "base 1'7)" memory are called up, and if this is the data of "number a on the left", it is changed to the data of "200-a", and then When the data is “c number on the right”,
Change the data to “1990c” and use “200bitsJ”.
After converting into data corresponding to the bit address of the memory, it is written to the "base" register (see Figure 45) in the internal RAM, and "299" is written to the "selection right" register and "100" is written to the "diameter left" register. ”, and then call the content “d” of the “MoRight 1 [41]” memory to write the data “Right” ~
The data “d” corresponding to the bit address of the “reverse left” memory
After converting to ``-1'', the data is written in the ``model right'' register, and the data obtained by converting in the same manner based on the contents of the ``model left 1{3}-memory'' is written in the ``model left'' register.

Next, switch SW, which is one of the needle selection mode setting means,
1. In order to realize the pattern change based on the contents of SW2, shift to the pattern change fJ flow shown in FIG. 72 and correct the address data of the customer at the register.

In other words, refer to the contents of @2 and ■3 registers, and if forward/reverse soldering, SW2 and left/right soldering, and SWI are all OFF, leave the contents of ■register as is and select one of the registers. SW2
If only is ON, change the 3rd bit of the register (instructed from the lower order, the same applies hereafter) to the complement, for example, if it is "0", it will be changed to "1", if it is "1", it will be changed to "0". Correct the contents of ■register from "8" to "C" by changing it, so that the address of the "reverse right" memory can be specified. Also, when only VWI is ON, the contents of ■register 2 bits Change the number to multiple and correct it from "8" to "A", thereby making it possible to specify the address of the "correct left" memory, and
If both W1 and SW2 are ON, (2) change the second and third bits of the register to complements and correct from "8" to "E", thereby allowing the "reverse left" memory address to be specified. ■When at least the second bit of the register is changed to the complement, the content of the "Moright" register is changed from "e" to "59-e".
” data is calculated, and from the contents “h” of the “Jōsa” cash register, “
Calculate the data of ``59-h'', write the ``591e'' data to the ``Mosho'' register, and write the ``59-h'' data to the ``Shinyu'' register, and write the ``Shozu'' specified by both registers. , the bit address number common to the "reverse left" memory is made to correspond accurately to the information effective width data in each memory of the above-mentioned "Makuzo 1 (3) 1" and "MakuRou 1 {41" 1. Next, When the control is completed according to the flow of "Pattern change 1" above, the contents of the corrected "model right" and "model left" registers are saved to the "model right'" and "model left'" registers, and After the contents are saved in the ○f' register, initial data "0" is stored in the 3 register for double counting, and the contents of the "base" register are called and written in the "carriage COUNT'" register.

And SW4, SW which is one of the needle selection mode setting means
In order to realize the pattern change based on the contents of 5, the 73rd
Shifting to the “pattern change 2” subroutine shown in the figure,
■Re-correct the address data of the customer at the cash register. That is, referring to the contents of ■0 and ■1 registers,
If facing W5 and both SW4 are OFF,
■If you leave the contents of the register as is and only one SW5 is ON, ■Change the third bit of the register to the number of buckets, and change the contents of the register to ``If it was 8J, change it to ``C'', if it was ``C,''Ba"
8J, re-correct "A" to "E", "E" to "A", and if only SW4 is ON, change the second bit of the register to the complement and change the contents of the register. , if it is "8", it is changed to "A", if it is "A", it is changed to "8", if "C" is changed to "E", if "E" is changed to "C", and SW4
, 5 are both ON, ■ Change the 2nd and 3rd bits of the register to the complement, and if the register contents are "8", change it to "E".
”, “E” becomes “8”, “A” becomes “C”,
If it is "C", it is re-corrected to "A". ■Reduce the number of cash registers by 2
When the bit number is changed to the number of buckets, the data for the "Model Left" and "Model Right registers are corrected in the same way as in "Pattern Change 1" above, and then the process returns to the flow in Figure 71. Next, the MPU According to the flowchart in Figure 71, change the contents of the “Mosa” register to “Hai COUNT”
After writing to the register, at that time ■ the required bits of the "regular right" to "reverse left" memory specified by the register at addresses AO to 3, and also specified by the "simulation COUNT" register. Call the contents of “0” and “1” of the address,
“Carriage CO” only when the bit content is “1”.
Write "1" to the bit address of the "20 ribs" memory specified by the "UNT'" register. Then, after writing, on the condition that the contents of the "Carriage COUNr" register do not match the contents of the "Selection" register, the "Carriage C
If "1" is added to the contents of the "OUNT'" register, and data "0" with no horizontal double is stored in the ■2 register, the contents of the "Mock COUNT" register will be the same as the contents of the "Mock right J register". Provided that they do not match, change the contents of the ``Model COUNTJ'' register to ``
1'' is added, the process returns to the above-mentioned final bit write flow and repeats the same operation. If, “Mo COUNT
” If the deposit in the cash register matches the contents of “Moright”, the process returns to the subroutine of “Pattern change 2” and repeats the same operation as above, but sometimes the “Carriage COUN”
If the contents of the "r" register match the contents of the "select right" register, then check whether the contents of the "select left" register match the "base" register, and if so, enter the ◎2 register. End data “0”
” is stored, the interrupt flag is unmasked, and the flag test is performed to complete the control of the flow shown in Figure 71. However, if the contents of the “Select” register do not match the “Basic” register, the After evacuating the Taniuchi customers at the ``Mou''' and ``Bakuza'' cash registers to the ``Shinza'' cash register, and returning the contents of the ■' cash register to the ■ cash register, ■ ” and “
The data obtained by subtracting 71'' from the contents of the ``base'' register is written to the ``carriage COUNT↑'' register, and the contents of the ``model right'' register are written to the ``model COUNT'' register.

At that time, the addresses AO to 3 are specified by the ■register at that time, and the required ones of the "normal right" to "reverse left" memory are specified, and also "0" of the bit address specified by the "simulation COUNT" register. , "1", and only when the bit content is "1", "1" is written to the bit address of the "200 bits" memory specified by the "carriage COUNr" register.

After writing, the contents of the "carriage COUNT'" register are set to "1" on the condition that the contents of the "carriage COUNT'" register do not match the contents of the "selection left" register.
If the data "0" without double double is stored in the ■2 register, the "mock COUNT" register is subtracted, and the "mock COUNT" is
After subtracting ``1'' from the contents of the ``T'' register, the process returns to the above-mentioned final bit write flow and repeats the same operation.

If the contents of the "Model COUNT" register match the contents of "Model 1", the process moves to the "Pattern Change 2" subretin and repeats the same operation as above, but sometimes ,
If the contents of the "Carriage COUNT'" register match the contents of the "Kiri-Sada" register, the end data "0" is placed in the ◎2 register.
is stored, the interrupt flag is unmasked, and a flag test is performed, and then the control in the flowchart of FIG. 71 is completed.

In addition, in the memory write operation for the above bit content "1", if "1" data with a horizontal double is stored in the ■2 register, the ■3 register that previously stored "0" will be valid. After adding ``1'' to or subtracting ``1'' from the contents of the above ``Carriage COUNT''' register, by asking the contents of the ■3 register, if this is ``0'', then `` 1” and immediately returns to the above-mentioned final bit write flow. However, if it is “1”, it is rewritten to “0” and the “1-1” or “1
” Shift to a subtraction flow.

Therefore, the "correct right" specified in the "mock COUNT" register ~
The bit address content of the desired one in "reverse left" memory is "
``20 plates it'' specified in the ``carriage COUNT''' cash register.
For example, when the content of bit address ``20'' of the desired memory in the ``normal right'' to ``reverse left'' memory is ``1,'' 200bitsJ〆Mori bit address ``
100" and "101".
Next, according to the flowchart in Figure 71, ■ ``1 too'' at the cash register.
If "1" data representing
``Select right 1 {6''' ``Rhishi left 1'5}'' Recall each content of the memory and use the result data obtained by the same conversion correction as above,
In addition to writing in the ``Ki J ``Sen Right'' and ``Sen Left'' cash registers, ``
Model right 1 [4' 1, "Model 1'3'1" Recall each content of the memory and use the result data obtained by the same conversion correction as above.
Write “Mo right” and “Mo left” on the cash register.

Then, the same control as in the case of the above-mentioned "Everything" is repeated, and after the execution, the flow control shown in FIG. 71 is completed. Furthermore, according to the flowchart in Fig. 71, if the ■register stores the data "2" representing "2 too", the M-yen U rewrites the contents of the ■2 register to "1" in advance, and then
At the beginning of the data memory write operation, "Moyo 2"
``Basic 2'C} level'' to perform a bit write operation
Select right 2 {B'” “Sen left 2 Yōzan” Mo right 2 ■ 1, “Mo left 2'
8' Recall each content of the memory and write the data obtained by the same conversion correction as above to the "Ki", "Sen-R", "Sen-S", "Maku-R", "Mo-S" registers, and then, "Pattern change 1"
The process moves to the flow of , and the same control as above is repeated.

In particular, in the bit write operation of "Moyo 2", the MPU
Following the flow of "pattern change 1" and "pattern change 2", ■ without correcting and re-correcting the address data that is the contents of the register, the data of "8" stored at the beginning, that is, the "correct right" memory is Leave the specified address data as is,
Move to bit write flow. Therefore, for "Moyo 2", the MPU turns on left and right soldering, SW1, forward and reverse soldering SW2, facing SW4, and forward and reverse repeating SW5.
, by not realizing a pattern change based on the OFF content, and by storing "1" data in the ■2 register first, ■
3 registers are not used effectively and bit writing processing is not performed for "double double". Then, according to the flowchart in Figure 71, the MPU that has finished the bit write operation for "Moyo 2" rewrites it to "2" based on the previously stored content "1" of the ■2 register. , "Momo1" bit write operation is performed, "Basic1'71", "Selection1(6}1", "Selection1{5}1", "Moyo1{4'1", "
Shinza 1'3} Recalling the contents of the memory, the data obtained by the same conversion correction as above is converted into ``Kiha ``Senryu'', ``Hishiza''.
, "Mo right J "Mo left" Write in the cash register.

Then, the same control as described above is repeated, and after the execution, the control in the flow of FIG. 71 is completed. Also, according to the flowchart in Figure 71, if data "1" with double amikomi is stored in the MP Yamama register, the @0 register will be used effectively, for example, the first In the control of the flow shown in Figure 71, first change the 3rd bit of the ■register that stored the data of 8J to the complement, change the contents of the register from "8" to "C", and similarly, in the second ■ Leave the contents of the cash register as "8" and continue for the third time ■ Leave the contents of the cash register as "8" and change it to "8" to "C" for the fourth time After that, it returns to the first time and operates to create the same change.

As is clear from the "MOY0 SW" flow in FIG.
Since "1" data for forward and reverse soldering is stored in the register, when executing ■register correction for "pattern change 1" according to the flow shown in Figure 72, the third bit of the register is set to the pail number. There is nothing to change. Moreover, as is clear from the flowchart in FIG. 70, when the sheet 59 is fed and returned in a double-threaded state, the carriage is fed or returned by two steps in two runs. Based on the driving, the contents of the above ■register will be "C", "8", "8", "Ch 'C", "8", '8', C'C "8", etc., respectively. In this case, the signals on the same level on sheet 59 are processed twice, ``forward one'' and ``reverse one''.
This is performed twice for each row of signals on 9, thereby making it possible to select needles for so-called double knitting. According to the flow shown in Fig. 71, the various switches SW1, 2, 4, and
N, OFF Based on the contents, the first storage device "correct right"
~ Select the desired item in the “reverse left” memory and store the “1” bit contents in the second storage device “20 plates itsJ”.
The operation of writing to a predetermined bit address in the memory can be easily understood from the embodiment diagrams of knitting patterns illustrated in FIGS. 49 and 50. In particular, in the flow shown in Fig. 71, by effectively utilizing the memories from ``normal right'' to ``reverse left'', and by specifying the address data of the customer inside the cash register, the bit arrangement according to the required lotus needle mode can be set. Ranking or “0” “1”
”, and furthermore, switch SW3, which is one of the needle selection mode setting means, is turned on and off.
By writing the same bit content "1" to every two consecutive bit addresses of the "20 dishes its" memory based on the F content, the double chocolate mode is handled very easily.
Therefore, after the control in the flow shown in FIG. 71 is completed, the key input data memory "start stage
1-" to "Basic 2} Referring also to the contents of 1, the needle selection data necessary to realize the knitting pattern set by all needle selection mode setting means is in one-to-one correspondence with the knitting needles. Corresponding with “
In each bit address part of the memory of ``20 plates its'', the data of ``with needle selection (knitting needles selected at position B in Figure 3)'' is set to bit content ``1'', and the data of ``without needle selection (knitting needles selected at position A in Figure 3)'' are set to ``1''. The data of the knitting needle to be selected) is stored as bit content "0". According to the main flow shown in FIG. 60, when the MPU performs an external interrupt flag test during the key scan operation in the "data input mode", if the "IRQ" signal is output, the MPU immediately performs the flag test shown in FIG. Shifts to the external interrupt flow shown in , and also in "organization mode",
If the "IRQ" signal is output in the state where the external interrupt is unmasked, the process immediately shifts to the interrupt flow shown in FIG. 74, and, for example, according to the control flows shown in FIGS. 68 and 70,
Interrupt flag test instructions (not shown) inserted here and there when the interrupt flag test was performed or during the "60→200 bits" control in the flow shown in FIG.
According to the flag test, if "IRQ
” signal is output, the flow immediately shifts to the interrupt flow shown in FIG. 74, and returns to the original flow after the required interrupt control is completed.

Below is the external interrupt flow shown in FIG.

1, to explain the control operation of the MPU, first, by temporarily setting "F" in boats RO~3,
RESET” signal is output, and the carriage position detection circuit 1
30 JK type FFs are reset, the Q output signal "IRQ" signal is returned to "H", and the next opportunity is set to "L".
” is ready to output the “IRQ” signal. M.P.
According to the flowchart in FIG. 74, U first asks whether the "left reference" signal is "H", and if so, and "F
When the "WD" signal is "1" indicating rightward movement of the carriage, left-based count correction is performed.

That is, when one of the K and L carriages is traveling rightward from the left end of the needle bed and one of the magnets 42 to 44 mounted on the carriage approaches the left reference element 40 (see FIG. 31b). Based on the “IRQ” signal, MP Yamama, Carriage CO
Store "Satoshi" in "C. REG" for UNT, and if the "phase" signal at that time is "1", write "E" in "Nd" register for needle selection count, and set it to "0". If so, write 6J and complete external interrupt processing. 12th
As can be understood from the figure, when the left magnet 42 of the K carriage 13 or the magnet 44 of the L carriage 20 approaches the left reference element 40', the electromagnet SL is moved while satisfying the timing shown in FIG. The bit address number corresponding to the knitting needle to which energization is to be started is "group", and in addition, the bit address number corresponding to the knitting needle to which energization is to be started is "group", and the state in which the belt and carriage are connected when the "phase" signal of "1" is output, There is an electromagnet SLE corresponding to the compatible cam theory position, and it is also "0".
When the "phase" signal is output, there is an electromagnet SL6.

Therefore, by performing the left reference count correction as described above, subsequent needle selection timing can be secured. However, when the right side magnet 43 of the K carriage 13 comes close to the left reference element 40, the same count correction as described above is performed, but as the carriage 13 continues to move to the right, the left side magnet 42 moves closer to the left reference element 40. close to the left reference element 40;
By correcting the count at that time, the needle selection timing shown in FIG. 9 is secured. Also, M-yen U follows the flow in Figure 74,
When the "right reference" signal is "H" and the "FWD" signal is "0" indicating that the carriage is traveling to the left, a right reference count correction is performed.

That is, when one of the K and L carriages is traveling leftward from the right end of the needle bed, and one of the magnets 42 to 44 mounted on the carriage approaches the right reference element 38 (Fig. 31a). Based on the “IRQ” signal, the MPU selects the carriage COU
In addition to storing "301" in "C REG" for NT,
If the "phase" signal at that time is "1", write "9" in the "Nd" register for the needle count, and if it is "0",
Similarly, "1" is written to complete the external interrupt processing. As understood from FIG. 11, when the right magnet 43 of the K carriage 13 or the magnet 44 of the L carriage 20 approaches the right reference element 38, the electromagnet SL is moved while satisfying the timing shown in FIG. The bit address number corresponding to the knitting needle for which energization should be started is "301", and the state in which the belt and carriage are connected when the "phase" signal of "1" is output is suitable for starting energization. There is an electromagnet SL9 corresponding to the cam wheel position, and an electromagnet SLI is present when a "phase" signal of "0" is output.

Therefore, by executing the count correction of the right reference as described above, subsequent needle selection timing can be secured. However, when the left side magnet 42 of the K carriage 13 comes close to the right reference element 38, the same count correction as described above is performed, but as the carriage 13 continues to move leftward, the right side magnet 43 moves closer to the right reference element 38. close to the stone reference element 38;
By correcting the count at that time, the needle selection timing shown in FIG. 9 is secured. Also, the MPU follows the flow in Figure 74,
When the carriage starts traveling from the end of the needle bed, if either the "left reference" or "right reference" signal is "H", the "carriage 1" signal is displayed in the ■3 register for the carriage direction flag. Stores “1” if the vehicle is running to the right, and stores “0” if the carriage is moving to the left.
" is stored and used for subsequent detection of carriage travel and reversal.

According to the flowchart in Fig. 74, the M-circle U that executes the external interrupt operation every time the "IRQ" signal is output is based on the fact that the "left reference" and "right reference" signals are usually "L". , If the “FWD” signal is “1” on the right side, “C・REO”
" Add "1" to the contents of "Nd" register and calculate "1-1" to the contents of "Nd" register. Provided that the contents of ■3 register at that time is right drive "1", after addition " For example, the contents of the bit address of the "20 rows" memory, which is the first storage device, specified by the contents of "C.REG" are called.
Bit address “12” that matches the content “120” of “G”
Recall the contents of '0''1' of '0'. When the bit content is “0”, “2” represents “no needle”.
” data is serially transferred to the SPU, and then based on the start of the transfer clock from the SPU, the “Nb” data after the above addition is
The number data "x" of the electromagnet SL, which is the contents of the register and is to be energized at that time, is transferred to the SPU. If the retrieved bit content is "1", the "1" data representing "needle selection" is transferred to the SPU, and then the "Nd" register is transferred based on the transfer clock activation from the SPU. In this case, there is no electromagnet SL to start energizing, but the number of the electromagnet SL to be cut off is sent to S.
The data is used for indexing on the PU side. Also, "FWD"
If the signal is “0” to the left, M circle U is “C・REOJ”
Also, the contents of the "Nd" register are each subtracted by "1", and based on the contents after the subtraction, the same recall from the "200 bitsJ memory" as described above or transfer to the SPU is performed.

In addition, the addition and subtraction of the "Nd" register is expressed in 1 gold falcon. For example, when "1" is added from "F", it becomes "0", and "O
When "1" is subtracted from J, it becomes "rF". However, according to the flowchart in FIG. 74, when the MPU inquires about the open/closed state of the hatch 1 19 using the ON/OFF contents of the micro switch 1 12, if the hatch 1 19 is "open," then the MPU calls from the memory. "2" data representing "no needle selection" is always transferred to the SPU, and then "Nd"
Transfer the contents of the register.

As can be understood from FIGS. 10 to 12, the 20 knitting needles 3 on the needle bed correspond to bit addresses "100" to "299" of the "200bits" memory in a pairwise relationship, and , in each of their bit address parts "
0", "IJ needle selection data is stored.

Therefore, after first performing the count correction on the left reference, in detail, the carriage center lines C and D arrive at the approximate center position between each line needle 3 in relation to the movement of the carriage for one pitch of knitting needles. Since the "IRQ" signal is output every time, based on this, the MmU which controls the flow shown in FIG. 74 for each output has the necessary relationships as shown in FIGS. At that time, select the electromagnet SL to start energizing or call up the needle data, etc.
More specifically, the selection cam mechanism 16, 16 mounted on the carriage
A and handle plates 45a to 45h cooperate to ensure needle selection timing, and all needle selection control is executed in a certain order.

Sometimes, according to the flow in FIG. 74, the MPU
Before adding "1" to or subtracting "1" from the contents of "G", only if the contents are "200", "1" is sent to the sensor argument flag ■ "1" as a sensor reading start command to the cash register
At the same time, "0" indicating that the carriage has passed through the center is stored in the carriage reversal flag register.

Therefore, after executing the external interrupt process in the flow in FIG. 74, the MPU returns to the main flow in FIG. 60 and proceeds with the control.
(2) Based on the fact that the register contents are "1", the "sensor discussion" control etc. in the flowchart of FIG. 68 is executed. Also, the 74th
According to the flowchart in the figure, when the carriage reverses its running direction, for example, from left to right, the MPR that performs external interrupt processing based on the "IRQ" signal that is output immediately thereafter・After adding “1” to the contents of the “REG” and “Nd” registers, since the contents of the @3 register is “0” for left travel, rewrite it to “1” for right travel, and then reverse the carriage to the right. Perform count correction.

In other words, if data "1" without the base version is stored in @1 register, "28" is subtracted from the contents of "C REG" after the above addition, and the contents of "Nd" register are changed to " C” is subtracted, but the data “0” with lace bran in ■1 register is also subtracted.
is stored, change the contents of “C・REG” to “4”.
” is subtracted, and the contents of the “Nd” register are subtracted by “C” to perform count correction. As can be understood from FIG. 10, for example, when the K carriage 13 is traveling to the left, the bit address number corresponding to the knitting needle 3 whose electromagnet SL is to be energized, that is, "
If the content of "C・REO" is "206" and the content of "Nd" register is "A", then if the carriage reverses its running direction and runs to the right, this will result in:
The bit address number corresponding to the knitting needle 3 for which the electromagnet SL should start energizing becomes "179", and the electromagnet SL
The number becomes "F".

Moreover, if it is an L carriage 20, it will be "203" and "F". Therefore, by performing the carriage inversion right count correction as described above, subsequent needle selection timing can be secured. Also, according to the flowchart in FIG. 74, when the carriage reverses its travel from right to left, the MPU blocks the "IRQ" signal that is output immediately after that, and when performing external interrupt processing, the "C.REG" signal is output. Also, after subtracting IJ from the contents of the "Nd" registers, ■Since the contents of the register 3 are "1" for right travel, rewrite it to "1" for left travel, and perform count correction for carriage reversal to the left. .

In other words, if data "1" without the base version is stored in the @1 register, the contents of "C REG" after the above subtraction are calculated as "28-1", and the contents of "Nd" register are “C” is added, but the same data is “0” for ■1 register with the base edition.
is stored, change the contents of “C・REG” to “4”.
” is added, and the contents of the “Nd” register are added “C” to perform count correction. Therefore, when the carriage reverses its travel from right to left, a count correction opposite to the aforementioned reversal of travel from left to right is performed to ensure the subsequent diamond hand timing. Then, according to the flowchart in Fig. 74, before correcting the carriage inversion right and left counts, the MPU inquires about the contents of the cash register, and only if "7" data indicating that the carriage has passed through the center is stored therein. ,
Stores "1" as a memory bit write command. Therefore, after executing the external interrupt process in the flowchart of FIG.
The MPU that returns to the main flow in Figure 0 and proceeds with control is ■
Since the content of the register is "1", the "60→200 bits" control in the flow shown in FIG. 71 is performed. Young ■
If "0" is not stored in the register, but data of "2" is stored, the MPU will leave the contents of the register as is and block the carriage reversal at that time.
60 → 20 other iP" control is not executed. That is, the carriage passes near the center of the needle bed, and in detail, the
Only based on the carriage reversal after the content of "O" becomes "200" and the "IRQ" signal is output, "60→
200bits” control is executed. Even if the "left reference" signal is "H", the MPU operating according to the flowchart in FIG. 74 does not perform left reference count correction if the "FWD" signal is "0" in the left direction. Even if the "right reference" signal is "H", if the "FWD" signal is "1" in the right direction, the right reference count correction is not performed. In other words, when the carriage moves from the inner side of the needle bed toward the outer end, the reference correction is not performed and the normal "C.RE
By executing the "1" addition/subtraction operation of the "G" and "Nd" registers, the needle selection timing over all the knitting needles on the needle bed is ensured. By the way, when the MPU, which operates according to the flowchart of FIG. body 42
When one of the magnets 42 to 44 approaches the reference elements 38 and 40 and detects that the reference correction position is also the carriage reversal position, that is, one of the magnets 42 to 44 approaches the reference elements 38 and 40.
If the carriage is reversed at a position close to 0,
(2) Rewrite the contents of the 3 register so that the carriage reversal correction will not be performed again immediately after that, and (2) Inquire about the contents of the register and execute the same process as in the carriage reversal correction described above.

The timing of these reference corrections and carriage reversal corrections can also be understood from FIGS. 26 to 29.
In this example, the mode of needle control performed by the cooperation of the MPU and SPU can also be understood from the block diagram in FIG. The relationship between signal transmission and reception is clearly indicated. Next, to explain how to use this example, first, hatch 119 is opened and pattern selection switch SWO is set.

For example, if you want to realize a knitting pattern that repeats continuously over the entire well direction of the knitted green space using the knitting pattern 64 arbitrarily selected on the sheet 59 which is the recording soot body,
If you want to create a striped pattern only on the desired part of the knitted fabric by setting it to "Moyo J" and using the knitting pattern 64 selected as "Moyo 1", set it to "Moyo 1". , Also, on the same sheet 59, "Moyo 1" and "Moyo 2"
If you want to embody a knitting pattern on a desired part of the knitted fabric by using two knitting patterns 64 selected separately in ``,
2. Set it to "Moyo". Next, press the pattern selection switch S
Data input points necessary for realizing each knitting pattern according to the set position of WO are sequentially called by lighting the lamps LI to L12 for each operation in step-113, so the points of the lit lamps LI to L12 are called. For each, desired data is keyed.

For example, "1 moyo" and as illustrated in FIG.
25 The knitting pattern 64 of "Moyo 1" included in the first pixel area is effectively used, and on the needle bed 2, the pattern reference position corresponding to the first pixel area of 1 is moved to the right knitting needle 3. If you decide that you want to embody the knitting pattern from the 5th stitch on the left to the 3rd interval of the green needle on the 50th needle on the right, respond to the lighting of lamp LI, set "1" to the number of layers, and also set "30" on lamp L2. , counterfeit "1" with lamp L3, counterfeit "25" with lamp L4, and counterfeit "50" with lamp L5 after operating the left key 114.
", and after operating the right key 115 at lamp L6, select "5".
0" as the layer number, and after operating the right key 115 at the lamp L7, "1" as the calendar number.

If the OK lamp L13 lights up, this will cause
You will be notified that the data entry is complete, so cancel the key river operation. If it is "All", there is no call to turn on lamps L5 and L6, and lamp L7 is lit next to lamp L4, so all you have to do is key the pattern reference position data "Right 1". . Also, "2 moyo", for example, the 52nd
As illustrated in the figure, on the same sheet 59, the knitting pattern 64 of ``Moyo 1'' included in the pixel area of ``1'' to ``25'' ranges from the 1st row to the 3rd row. , “2
Using the knitting pattern 64 of "Moyo 2" included in the pixel areas numbered 6" to 50, find the reference position of "Moyo 1" corresponding to the pixel area of number IJ on the needle bed 2. , select knitting needle 3, number 1 on the right, and create a green pattern between the striped needles 3 from 5 on the left to 5 on the right, and at the same time, create 26 knitting needles corresponding to the 1st pixel area. If you want to set the reference position as the 76th flea on the right and create a bran pattern across 3 green needles from the 51st right to the 100th green needle, do the same as in the case of ``1 Moyo'' above.
In response to the lighting of lamps LI to L7, key-in each data, and then in response to the back light of lamp L8,
``26'' is the layer number, ``50'' is also counterfeited with the lamp L9, and ``51 on the right with the lamp LIO,'' with the lamp LII.
100 meters on the right At lamp L12, ``Key the data on right 76J.''

However, in each of the above cases, the data that is turned on when the lamp L7 is lit is "left 50 instead of right IJ",
Either "Left 25" or "Right 26" may be pressed, and the data that is pressed when the lamp L12 is lit is "
Instead of "Right 76", "Right 5L" may be used, and the same line pattern is realized as a result.

As can be understood from FIG. 52, the information effective width of the knitting pattern that is desired to be effectively used on the sheet 59 can be freely selected according to the worker's preference. You are free to specify them in completely separate ranges, or you may specify them in ranges that overlap with each other, or even in completely the same range as shown in Figure 53. You are also free to specify.

Moreover, the cotton patterns corresponding to "Moyo 1" and "Moyo 2" are placed at mutually independent pattern reference positions on the needle bed 2 within different needle selection ranges, as shown in FIG. 52, for example. It is also possible to implement the knitting pattern 64 on the sheet 59 in various ways, and it is also possible to implement the knitting pattern 64 on the sheet 59 in various ways. By doing this, you can realize various knitting patterns. Next, after completing the operation of the key IN data as described above, edit the various SWs 1 to 6 and 8 as they are based on the knitting pattern 64 of "Moyo 1" selected on the sheet 59. Operate the required switches depending on your wishes, such as whether to embody a pattern or to print left and right directions.

In particular, when knitting the well-known sheath stitch using the L carriage 20, operate the sheath stitch SW9,
Also, when knitting the well-known double amikomi stripes using a rubber knitting machine, double amikomi SW7 is operated, but other switches may not be compatible with both knitting operations. For example, be careful not to operate the horizontal double switch 3 when on the race line. As understood from FIGS. 49 to 51, the knitting pattern 64 can be varied in various ways by operating various switches, and various vertical patterns can be realized without creating a large number of sheets 59. As mentioned above, after operating the key SW operation mechanism 105, which is the lotus needle mode setting means, inputting the data necessary to realize the desired knitting pattern, and determining the needle selection mode, the next step is O.
K lamp L13 is lit, rice is in the paddy state, and key 1 is pressed to start rice cultivation.
17, and then close the hatch 119. and,
The sheet 59 serving as the required recording material is mounted on the reading mechanism 65, and using the manual feed dial 73 or the manual feed knob 91, the sensor 77 detects that the first stage of the range of the knitting pattern 64 selected on the sheet 59 is In other words, the sheet 59 is set so as to correspond to the reading position J (see FIG. 5). After that, when starting knitting, for example, two-color simultaneous knitting, the K carriage 13 is moved from one end of the needle bed 2, at least in the initial stage of knitting, so that the magnets 42 and 43 mounted on the carriage are The reference elements 38, 40' are caused to run from the outer end of the adjacent position, and then run to the other end.

At this time, when the K carriage 13 passes near the approximate center of the needle bed 2, sensor reading and sheet feeding are performed.
The column signal of the first stage pixel area 61 is read, and required pattern data is written into the "normal right" to "reverse left" memories, which are the first storage devices. Next, when the K carriage 13 is run again from the other end to the one end, the required data in the first storage device, ``normal right'' to ``reverse left'' memory, is retrieved immediately after the movement is reversed. , based on the contents of the switch SW etc. which is the needle selection mode setting means, the "20" which is the second storage device is
The bits corresponding to each bran needle are stored in the "sailing ship" memory as data with or without needle selection, and the contents of each bit address in the "200 bits" memory are sequentially output every time the knitting needle 3 of the K carriage 13 runs by a pitch. After the K carriage 13 travels, the knitting needles 3 are sorted into two positions A and B, front and back, and are led out as a so-called backward needle selection type.

Therefore, in this example, to start the required pattern knitting,
After the K carriage 13 has run twice in advance, knitting of the first stage can be started, and after the pattern for the needle selection of the first stage has been created, the K carriage 13 can be moved to the desired pattern cam arrangement. For example, if you are using bran with two-color threading at the same time, set the desired striped thread and start knitting.

From then on, all you have to do is run the K carriage 13, and the sensor control and sheet feeding are automatically controlled depending on whether it is running to the left or right. feed control is notified), the side fabric that embodies the desired knitting pattern can be easily knitted. In particular, when the electronic buzzer pattern continuously sounds and the continuous return control of the seat 59 is notified, carriage travel is stopped until the end of the notification and then resumed, thereby causing the green pattern to change. No disturbance occurs. In the middle of the above pattern knitting, K
If you want to check the needle selection pattern being created at that time with the carriage 13 stopped at the end of the needle bed 2,
Referring to FIG. 17, for example, if the sheet 59 is being fed vertically in reverse, the manual feed knob 91 can be pushed in and rotated from "editing" to "returning". The row of observable pixel regions at position K in FIGS. 5 and 18 can be easily confirmed as pattern information matching the needle selection type described above.

After checking, if the manual feed knob 91 is pushed in again to return from "return" to "knitting", the subsequent feeding order of the sheets 59 will not be disturbed. Also, in the same way, sheet 5
If the needle 9 is in normal stage feeding, the shape of the transparent needle can be easily confirmed by operating from "line" to "advance". However, care must be taken as it cannot be used in vertical or double folding cases. In particular, in this example, if you want to know the number of rows of pixel areas on the sheet 59 that the sensor 77 corresponds to in the middle of knitting, all you have to do is open the hatch 119 and operate the row adjustment key 116. As a result, the contents of the "stage number REO" at that time are displayed on the layer number display section 111 in accordance with the corresponding number of stages of the sensor. Moreover, when the column alignment key 116 is operated after pressing the key m for arbitrary number data, in response, the pixel area of the column number matching the calendar number data is moved to the position corresponding to the sensor 77 on the sheet 59. is moved forward or backward, and the contents of "D.REG" are accordingly rewritten to match the calendar number data. Therefore, it is convenient to feed the sheet 59 to a desired number of stages very easily and, for example, to omit part of the knitting pattern 64 on the sheet 59 to realize a striped pattern. In addition, if you want to knit the patterns of the same row on the sheet 59 continuously during knitting, you can use the stop switch S.
All you have to do is operate WIO, and by doing so, K carriage 1
Based on the travel reversal in step 3, the "60 → 20 imitation its" control is not performed, and the required bit address contents are repeatedly read out from the "20 ribs" memory, which is the second storage device, and at the same time the sensor pattern alignment and sheet feeding are performed. etc. control is also canceled.

Therefore, it is convenient for realizing a knitting pattern in which the -row of the knitting pattern is partially extended vertically. Additionally, if you wish to temporarily stop pattern knitting during knitting, you can continue knitting with the hatch 119 open, and as a result, even if the K carriage 13 is running, the diamond needle timing can be ensured. In the current situation, the sorting operation of the knitting 3 is not performed, and in detail, all the knitting needles 3 are aligned and drawn out at the A position without diamond needles, and at the same time, the control of sensor planning and sheet feeding, etc. Canceled.

By the way, when knitting the well-known lace knitting using the L carriage 20, the L carriage 20 is placed at the left end of the needle bed 2 and the K carriage 13 with a flat knitting cam arrangement is used, as illustrated in FIG. at the right end of the needle bed 2, with the connecting pin 28a of the L carriage 20 set in a position where it can be connected to the belt 24, and with the connecting pin 28 of the K carriage 13 set in a position where it cannot be connected, then connect both carriages. By running alternately, especially the L carriage 20
Knitting proceeds by sorting the bran needles 3 using the sorting cam mechanism 16a.

At this time, by operating the SEA SW9, the needle selection timing suitable for the L carriage 20 is ensured. For example, even if the K carriage 13 is moved, the L carriage 20 is moved immediately after that. By being driven, the L at that time
It is possible to ensure needle selection timing suitable for the carriage 20.
In this example, the control configuration is such that the switch SWI~5, which is one of the transparent needle mode setting means, functions only for "Moyo 1", but for example, the same type of switch SWI~ 5 may be added to make it function for "Moyo 2", thereby making it possible to realize more diverse green patterns.

Moreover, even if it is one set of switches SWI-5, it is also possible to configure it to function as both "Momo 1" and "Moyo 2". In addition, in this example, the energization time of the electromagnet SL, which is a converting member, is set for approximately 13 pitches of the striped needle 3 from the "1" output latch of the corresponding boats RO to 15 to the "0" reset. Although the configuration is set during the driving period and does not allow continuous energization for a long period of time,
For example, by simplifying the reset control configuration, the above SPU
Based on the "needle selection" data transferred to , the boat R corresponding to the same data is reset to "0",
Thereby, it is also possible to freely energize the electromagnet SL during the carriage traveling period of about 16 pitches of the striped needle 3. As is clear from the details of the embodiment described above, the present invention provides digital electric signals obtained by reading knitting pattern information recorded on a required recording medium to bits corresponding to each position of the recording medium. Separately from the first storage device that stores bit contents, there is a second storage device that stores bit contents corresponding to each knitting needle on the needle bed. According to the needle selection mode setting means for setting whether to embody the bran pattern on the vertical fabric, the contents of the first storage device are read out and the contents of the second storage device are read out so that the changes set in advance by the mode setting means are realized. After storing it in the second storage device, the stored contents are outputted to the knitting needles corresponding to each bit in the second storage device in relation to the movement of the carriage, and the striped needles are sorted according to the contents. It is characterized in that, in particular, the output control operation of the stored digital electric signal related to the traveling of the carriage is made extremely simple, and for example, it is related to the setting contents of the needle selection mode setting means. It is an extremely simple control in which the contents of each bit of the second storage device are sequentially read out for each corresponding knitting needle in a one-to-one relationship, and the processing speed for processing can be sufficiently shortened. Not only can we provide an extremely superior needle selection method that satisfies even high-speed carriage running, but we can also easily change the knitting pattern on the recording medium by using the noisy general almanac key. - You can freely select and specify only the parts of the information you like.
Moreover, the selected knitting pattern information can be made to correspond to any bran needle on the needle bed, and the needle selection range can be freely specified to realize the desired knitting pattern only in any desired part of the striped fabric. To provide a lotus needle method for a knitting machine which can extremely easily knit original and varied pattern works particularly suitable for a home-use striped machine.
