An LCD drive circuit 47 is connected.

The second electronic control unit 20 executes a program stored in the ROM 23 to perform pattern selection processing, pattern formation processing, etc. in response to instructions from the numeric keypad 13, etc. In order to realize these processes, the ROM 23 ．． R.A.
M25. Each predetermined area of EEPROM 31 is assigned to a specific data structure.

Stitch data for forming a pattern by driving the motor drive device 39 and actuator drive device 45 is stored in advance in the ROM 23 on the pattern side.

In this area 1, as shown in Fig. 4 (A), the stitch data necessary to form - characters and symbols are combined into one set, and the entire stitch data of the - set is the pattern number N of -. pt.
It is configured to have a structure specified by n.

A pattern number storage area for storing this pattern number Nptn is set in the RAM 25.As shown in Figure 4 (B), the pattern numbers Nptn are stored side by side. Nptn is configured in a structure specified by the value of combination pointer P.

An area is set in the EEPROM 31 to non-volatilely store the sequence of pattern numbers Nptn.
As shown in FIG. 4(C) above, the pattern numbers Nptn are arranged in a structure that is stored together into groups, and each group is specified by the group number Ngrp. The group 1t of pattern numbers Nptn stored here corresponds to the pattern numbers Nptn stored in the RAM 25. In the example, group number N

In the sewing machine of the embodiment configured in this manner (in response to the operation of the upper key, the electronic control unit 20 executes the following processing,
Controls the sewing machine in response to key operations.

After the electronic control unit 201i is powered on and executes the initial processing, the pattern selection processing shown in the flowchart of FIG. 5(A) is performed. After performing a pattern selection process (operation key reading process (step 100)), the process of determining the type of operation key and executing a subroutine according to the function of each operation key is repeated to respond to the key operation. This is what controls the sewing machine.

Start processing and read operation key processing (step 100)
When this is done, first, a process for determining whether or not the operation key is the numeric keypad 13 is performed (step 110). The subroutine (step 120).

On the other hand, if it is determined in step 110 that the operation key is not the numeric keypad 13, then a determination process (step 130) is performed to determine whether the operation key is the start/end key 15 or not. If it is determined that it is the start/end key 15, a subroutine (step 140) is executed to set the start and end of the pattern number writing process to the EEPROM 31 executed in the subroutine of step 120.

If it is determined in the process of step 130 that the start/end key 15 is not the key, then a process of determining whether or not the operated key is the "10" key 17 is performed (step 150). "+" key 17

By executing the above processing, the electronic control unit 20 determines the type of operation key, and repeatedly executes subroutines and processing according to the function of the determined operation key, thereby controlling the sewing machine according to the operator's intention. .

Hereinafter, the processing performed by the electronic control device 20 will be explained according to the operation pattern.

(A) First, the processing performed by the electronic control unit 20 in an operation pattern in which a message pattern is not registered and a necessary pattern is formed only one time will be described. Use this operation pattern by combining the numeric keypad 13 and the "+" key 7.

When the numeric keypad 13 is operated, the electronic control unit 20 (upper) determines that the operating key is the numeric keypad 13 in the process of step 110, and shifts the process to the subroutine of step 120, ie, pattern number writing/reading process.

In the pattern number writing/reading process (as shown in the flowchart of FIG. 5(B)), the electronic control unit 20 fi
First, a process (step 200) is performed to identify a two-digit input number mn from the number of the operated numeric keypad 13.

When the 2-digit input number mn is specified, the "10" flag F
A process (step 210) is performed to determine whether or not pls is set. Since the "10" flag F pls is not set when the numeric keypad 13 is operated to input the first pattern, a negative determination is made in the process of step 210, and the combination pointer P is reset to the value rFFJ (step 220). The zero combination pointer P that executes is the pattern number Npt of the pattern corresponding to the input number mn.
It specifies the combination order of n.

Next, a judgment process (step 230) is performed to determine whether the input number mn is between 95 and 99, that is, whether the process is related to a message pattern. - When inputting a one-time pattern sequence (Friend) Since the input number mn input using the numeric keypad 13 is not number 95 or 99, a negative determination is made in the process of step 230.

Therefore, the process of incrementing the combination pointer P (step 240) is then executed, and the process of specifying the pattern number Nptn (mn) of the pattern corresponding to the input number mn (
Step 250) is performed. By specifying the pattern number Nptn, a set of stitch data in the ROM necessary for forming the pattern corresponding to the input number mn is specified.

When the pattern number Nptn (mn) is obtained in this way,

After this, when the numeric keypad 13 is operated, the electronic control device 20
executes the previous pattern number writing/reading process again. In this case (Y) In the process of step 210, the "+" flag F pl
If s is set, an affirmative judgment is made and step 2
The process of resetting the combination pointer P of No. 20 is not performed. In the subsequent process of step 230 (9) Since the input number mn is not number 95 or 99, a negative judgment is made and the process of incrementing the combination pointer P (step 2
40) and the pattern number Nptn (mn) from the input number mn
(step 250).

Next 1: The calculated pattern number Nptn (mn) is stored in a predetermined address specified by the incremented combination pointer P (step 260), and after the previous pattern number 1: the calculated pattern Store the number. In the process of step 270 (Y message flag F ms
Since g has been reset, a negative determination is made and the above processing is temporarily terminated.

Enter the number using the numeric keypad 13 like this, then press "+"
By repeating the operation of pressing the key 17, the electronic control unit 20 repeats the above-mentioned process, and the RAM 251:
, the pattern numbers Nptn are stored in the input order as shown in FIG. 4(B).

When the group number N grp is obtained in this way, a group of pattern numbers N ptn (N grp
) is read out (step 300) - Next, the group of read pattern numbers Nptn is stored in the RAM2.
Process of expanding the pattern number storage area in S to each memory M (
Step 310) and a process of registering the number of pattern numbers Nptn constituting the group of read pattern numbers Nptn as the value of the combination pointer P (step 320) are performed, and this process is temporarily terminated.

Note that as described above, steps 280 to 320
If nothing is stored in the EEFROM 31 even if the above processing is executed (above), the pattern number Nptn is not expanded in the RAM 25, and the combination pointer P
The value of is also kept at the value "F" in the process of step 220.

Depending on the contents of the previous operations, the display section 9 [1] displays the message number Nm5g at the beginning of the message number 1: as illustrated in FIG. 6(E) by a separate process performed by the electronic control unit 20.

Next press When the start/end key 15 is pressed, the electronic control unit 20
The process moves to the pattern number writing start/end process of the subroutine of step 140 (top).

In the second process (as shown in FIG. 5C), first, a process (step 330) is performed to determine whether the message flag Fm5g is set.

When numbers 95 to 99 are input using the numeric keypad 13 (since the message flag Fm5g is not set, a negative determination is made in the process of step 330, and it is determined that it is the start of memorizing the message pattern. Processing to set the message flag Fm5g (step 34)

and "+" key 17 repeatedly,
Pattern numbers Nptn corresponding to input numbers mn are stored in 25 and EEPROM 31 in the order of input.

That is, in the pattern number writing/reading process shown in the flowchart of FIG. P)l:, Pattern number Nptn (mn) corresponding to the operated numeric keypad 13
After performing the process of storing (step 260), an affirmative determination is made in the process of step 270 that the message flag Fm5g is set. Next, select the same pattern number Np that was stored in the RAM 25 in the previous step 260.
A process (step 350) of non-volatilely writing tn (m n) into the memory MEP (Ngrp, P) at a predetermined location in the EEPROM 31 specified by the group number N grp and the value of the combination pointer P is performed.

On the display section 91, by a separate process performed by the electronic control unit 20, the general shape of the pattern corresponding to the input number mn is displayed following the first message number Nmsg, as illustrated in FIG. 6(F).

In this way, the pattern number writing/reading process ends once, but then I: After operating the r 1 J key 17, the numeric key 1

and after displaying the first input pattern following this:
, displays the second input pattern.

(1) Next 1: In the operation pattern to be formed on the message pattern outer fabric registered in the process of operation pattern (a),
The processing executed by the electronic control device 20 will be explained.

When a registered number of a desired message pattern is entered from numbers 95 to 99 using the numeric keypad 13, the electronic control unit 20 starts the pattern number writing/reading process shown in FIG. 5(B).

In the pattern number writing/reading process (upper step 230)
In the process, an affirmative determination is made that the input number mn is between 95th and 99th.

Next, the process of setting the input number mn as the message number N msg and the group number N of the EEFROM 31 are performed.

In contrast, in the process of step 370, the message number N
If m5g is not the value IFFJ, a negative determination is made (e) Next, a determination process (step 400) is performed to determine whether the message flag Fmsg is set.

This is a state in which the message number Nm5g is not the value rFFJ and the message flag Fm5g is set (this is a state in which the message pattern explained in operation pattern (a) is being registered).

In this state, 1 above RAM specified by combination pointer P
When the process (step 410) of setting the memory M (P) at the predetermined location of No. 25 to the value "FF" is performed, In% EEFR
A process (step 420) is executed to set the memory MEP (Ngrp, P) at a predetermined location in the EEPROM 31 specified by the group number Ngrp of the OM 31 and the combination pointer P to the value "F"J.

Thereafter, a process of decrementing the combination pointer P (step 43o) is performed, and this process ends.

As a result, the pattern number Nptn written last in the RAM 25 and EEPROM 31 is canceled.
Return to the state before entering the pattern number.

On the other hand, in the process of step 400, the message flag F
If m5g is not set, it will be judged as negative (company)
For example, in operation pattern (1), a message pattern is read out using the numeric keypad 13 and the contents are checked, but in order to change the entire message pattern to form a different pattern, l:
,, In this case, when trying to erase the pattern number developed in RAM 25 (upper message number Nm5
The process of setting g to the value "FFJ" (step 440) and the process of setting the group number Ngrp to the value "F" (step 450) are performed. are all set to the value rF FJ (step 460), and the combination pointer P is set to the value rF F
Then, the process of changing the data to J (step 470) is performed. As a result, all pattern numbers Nptn developed in the RAM 25 are erased. In addition, the pattern number N p of this RAM 25
The sequence of pattern numbers Nptn stored in the FLEEPROM 31 is not deleted by canceling tn.

Each time the sewing machine of the embodiment described above stores the pattern number of the pattern selected with the numeric keypad in the RAM 25, the pattern number is also stored in the EEFROM 31, and this EEPROM
RA the pattern number stored in 3T using the numeric keypad.
Since it can be expanded to M25, names and other information that are expected to be used again can be stored in the EEPROM31 as a message pattern.
, and read it out using the numeric keypad ('L) This has the excellent effect of allowing the registered name to be formed many times. Therefore, the input effort is greatly reduced.

Also, each time you select a pattern using the numeric keypad, 1. T.EEPRO
Since the pattern number of that pattern is written in M31, the selected pattern can be saved even if you make a mistake such as turning off the power midway through. In addition, EEFROM3
By writing the pattern number in 1 for each selection, the time required to write all the pattern numbers into the EEFROM 31 can be shortened compared to writing all the pattern numbers at the end, improving usability.
