Abstract

PROBLEM TO BE SOLVED: To lessen the labor when combined patterns are utilized by a sewing machine again. SOLUTION: To register the patterns, an operator manipulates keys by combining a ten key, '+' and start and end keys. The number for the message pattern desired to be registered is selected from number 95 to number 99 and is inputted by the numeric keys. By this input, an electronic controller shifts to pattern number write and read processing and makes affirmative judgment that the input number mn is the number 95 to the number 99 (S230). Next, the input number mn is set as a message number Nmsg (S280) and the value (mn-95) subtracting the value 95 from the input number mn is determined cLS a group number Ngrp of an EEPROM. When the group number Ngrp is obtained, the controller carries out the processing (S300) to read out the group (Ngrp) of the pattern number Npt already written in the EEPROM region assigned by the group number Ngrp.

2. Description of the Related Art Some conventional sewing machines are capable of forming a name, a school name, and the like on a cloth by, for example, operating a numeric keypad to repeatedly select a character and combining the characters to input a name or a school name. .

In the conventional sewing machine, stitch data for forming a pattern such as a character by driving a sewing mechanism of the sewing machine is stored in advance in a ROM of a microcomputer of a control device of the sewing machine. Is repeatedly input, the pattern number of the character (pattern) designated by the input number is temporarily stored in the RAM, and when forming the pattern,
By sequentially reading the pattern numbers from the RAM, the stitch data corresponding to the pattern numbers is sequentially read from the ROM, and the sewing mechanism of the sewing machine is driven to form a name, for example.

[0004]

However, in the above arrangement, when a new pattern arrangement is formed, a new pattern number is stored in the RAM. Therefore, each time a pattern is formed, the ten-key operation is repeated to arrange the pattern arrangement. Has to be entered, and there is a problem in usability. Further, once the power is turned off, the pattern number stored in the RAM disappears. Therefore, in this case, it is necessary to repeat the operation of the ten keys to input the arrangement of the patterns when forming the patterns. Therefore, in the case of forming an arrangement of a pattern that is used many times, such as a name, for example, inputting each time becomes a complicated operation.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem, and it is possible to form a sequence of patterns to be repeatedly formed such as a name once by inputting once, for example, even when the power is turned on and off. An object of the present invention is to make it possible to easily correct a pattern to be selected and stored.

[0006]

To achieve the above object, a sewing machine control device of the present invention volatilizes one or more patterns selected by a pattern selecting means from a storage means storing a plurality of patterns. In a sewing machine control device for a sewing machine having a volatile storage means for temporarily storing and a non-volatile storage means for storing in a non-volatile manner, the control based on the operation of the canceling means.

In the embodiment, group numbers Ngrp are provided from No. 0 to No. 4, and five sets of pattern numbers Nptn are stored. The numbers 0 to 4 of the group number Ngrp correspond to the input numbers 95 to 99 of the numeric keypad 13 in sequence by the processing performed by the electronic control unit 20.

In the sewing machine according to the embodiment configured as described above, the electronic control unit 20 executes the following processing according to the key operation, and controls the sewing machine corresponding to the key operation.

After the power is turned on and the electronic control unit 20 performs an initial process, the electronic control unit 20 performs a pattern selection process shown in a seventh flowchart. The pattern selection process corresponds to a key operation by performing a process of reading an operation key (step 100), repeating a process of determining the type of the operation key and executing a subroutine corresponding to the function of each operation key. The sewing machine is controlled as described above.

When the process is started and the operation key is read (step 100), the operation key is
A determination process (step 110) for determining whether the number is 3 is performed. If it is determined that the key is the ten key 13, the pattern number of the pattern corresponding to the number input with the ten key 13 is stored in the RAM 25, and the pattern number of the pattern related to the message pattern is stored in the EEPROM.
A subroutine (step 120) for writing to M31 and reading from EEPROM 31 is executed.

On the other hand, the numeric keypad 1
If it is determined that it is not 3, then a determination process (step 130) is performed to determine whether the operation key is the start / end key 15.
If it is determined that the key is the start / end key 15, the EEPROM executed in the subroutine of step 120 is executed.
A subroutine (step 140) for setting the start and end of the process of writing the pattern number into the block 31 is executed.

Start / end key 1 in step 130
If it is determined that the number is not 5, the operation key is next the “+” key 1
7 is determined (step 150).
If it is determined that the key is the "+" key 17, the "+" flag Fpl
A process for setting s (step 160) is performed. This "+" flag Fpls is used in step 120 when the input is made by combining characters and symbols, such as the input of a name.
RAM 25 and EEPROM 31 performed in the subroutine of
The storage process of the new pattern number Nptn is a process of combining and storing after the last stored pattern number Nptn.

In the process of step 150, the operation key is "+"
If it is determined that the operation key is not the key 17, finally, a process of determining whether or not the operation key is the cancel key 19 (step 170) is performed. If it is determined that the key is the cancel key 19, the previous step 1
A subroutine (step 180) for canceling the pattern number written in the RAM 25 or the EEPROM 31 in the subroutine 20 is executed.

By executing the above processing, the electronic control unit 2
0 controls the sewing machine in accordance with the intention of the operator by repeatedly determining the type of the operation key and repeatedly executing a subroutine or a process according to the function of the determined operation key.

The processing performed by the electronic control unit 20 will be described below according to the operation pattern.

(A) First, processing performed by the electronic control unit 20 in an operation pattern for forming a pattern required only once without registering a message pattern will be described.
In this operation pattern, the ten key 13 and the “+” key 17
Operate in combination.

When the ten key 13 is operated, the electronic control unit 20 determines in step 110 that the operation key is the ten key 1
3 is determined, and the process proceeds to a subroutine of step 120, that is, a pattern number writing / reading process.

In the pattern number writing / reading process, FIG.
As shown in the flowchart of FIG.
First, a process (step 200) for specifying a two-digit input number mn from the number of the operated ten key 13 is performed.

When the two-digit input number mn is specified, "+"
A process for determining whether or not the flag Fpls is set (step 210) is performed. Since the "+" flag Fpls is not set when the ten key 13 for inputting the first pattern is operated, a negative judgment is made in the processing of step 210, and the processing of resetting the combination pointer P to the value "FF" (step 220) ). The combination pointer P is a pattern number Nptn of the pattern corresponding to the input number mn.
Is specified.

Next, a determination process (step 230) is performed to determine whether the input number mn is 95th to 99th, that is, whether or not the process is for a message pattern. In the case of inputting the pattern arrangement only once, since the input number mn input by the ten keys 13 is not 95th to 99th, a negative judgment is made in the process of step 230.

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

When the pattern number Nptn (mn) is obtained in this manner, the pattern number Nptn (mn) is stored in the memory M (P) at a predetermined address of the pattern number storage area in the RAM 25 specified by the value of the combination pointer P. Processing (Step 260)
Perform

Next, a process for determining whether or not the message flag Fmsg is set (step 270) is performed. This message flag Fmsg is the start / end key 1
By the operation of No. 5, it is set or reset in the subroutine of step 140. When the pattern sequence is input only once, since the message flag Fmsg is reset, a negative determination is made in the process of step 270, and the above-described pattern number writing / reading process is temporarily terminated.

In this way, the pattern number Nptn of the pattern input by the operated numeric key 13 is stored in the RAM 25, but the electronic control unit 20 displays the stored content on the display unit 9 for confirmation by another process. The display unit 9 first displays the input number mn of the numeric keypad for several seconds as illustrated in FIG. 11A, and then displays a pattern corresponding to the input number mn as illustrated in FIG. 11B. The outline shape is also displayed at the top.

Next, when the "+" key 17 is operated, the electronic control unit 20 sets the "+" flag Fpls in step 150. The electronic control device 20 displays the “+” sign on the display unit 9 following the display of the head pattern as illustrated in FIG.

Thereafter, when the ten key 13 is operated, the electronic control unit 20 executes the pattern number writing / reading processing again. In this case, a positive determination is made in step 210 that the "+" flag Fpls has been set, and the process of resetting the combination pointer P in step 220 is not performed. In the processing of the subsequent step 230, the input number m
Since n is not 95th to 99th, a negative judgment is made, the process of incrementing the combination pointer P (step 240), and the pattern number Nptn (m
n) is calculated (step 250).

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

As described above, the number is input by the ten keys 13 and
Next, by repeating the operation of pressing the “+” key 17,
The electronic control unit 20 repeats the above-described processing, and
5, the pattern numbers Nptn are stored in the input order as shown in FIG.

As shown in FIG. 11D, the electronic control unit 20 displays the display unit 9 in place of the "+" sign by a separate process, and displays the outline of the second input pattern after the first pattern display. Display the shape.

Here, when the start switch 7 is pressed, the electronic control unit 20 terminates the pattern selection processing described so far and starts another processing for forming a pattern. In the pattern forming process, the pattern numbers Nptn stored side by side in the RAM 25 are stored.
Are read in ascending order of the combination pointer P, and the stitch data of the set corresponding to the read pattern number Nptn is read from the ROM.
23, the sewing mechanism of the sewing machine is driven, and the input patterns are arranged and formed in the input order.

(A) Next, a process executed by the electronic control unit 20 in an operation pattern for registering a message pattern such as a name will be described. In this operation pattern, numeric key 1
In addition to 3 and the "+" key 17, the start / end key 15 is operated in combination.

First, a number for which a message pattern is to be registered is selected from the 95th to 99th numbers, and is input using the ten keys 13.

By inputting this number, the electronic control unit 20
Shifts the processing to the pattern number writing / reading processing shown in FIG.
An affirmative judgment is made that the number is from number 99 to number 99.

If an affirmative decision is made, then a process (step 280) for setting the input number mn as the message number Nmsg is performed. Subsequently, a process of obtaining a value (mn-95) obtained by subtracting the value 95 from the input number mn as the group number Ngrp of the EEPROM 31 is performed.

When the group number Ngrp is obtained in this manner, a group of pattern numbers Nptn (Ngrp) already written in the EEPROM area designated by the group number Ngrp.
Is performed (step 300).

Subsequently, a process of developing the group of read pattern numbers Nptn in each memory M of the pattern number storage area in the RAM 25 (step 310);
A process (step 320) of registering the number of pattern numbers Nptn constituting the group of n as the value of the combination pointer P is performed, and the process is temporarily terminated.

Even if the processing of steps 280 to 320 is executed as described above, if nothing is stored in the EEPROM 31,
25, the pattern number Nptn is not expanded, and the value of the combination pointer P is still set to the value “FF” in the process of step 220.

Depending on the operation contents so far, the display unit 9
FIG. 11 is a flowchart showing another process performed by the electronic control unit 20.
As shown in (E), the message number Nmsg
Is displayed.

Next, when the start / end key 15 is pressed, the processing of the electronic control unit 20 shifts to the pattern number writing start / end processing of the subroutine of step 140.

In this process, first, as shown in FIG.
A determination is made as to whether the message flag Fmsg is set (step 330). 9 on the numeric keypad 13
Since the message flag Fmsg is not set when the number 5 to 99 is input, step 3
In the process of No. 30, a negative determination is made, it is determined that the storage of the message pattern has started, and a process of setting the message flag Fmsg (Step 340) is performed.

In this way, the number keys 95 to 99 can be
After the number is input and the start / end key 15 is pressed, the ten keys 13 and the "+" key 17 are alternately and repeatedly operated as in the case of the pattern combination operation described in the operation pattern (a). And the input number mn in the EEPROM 31
Are stored in the order of input.

That is, in the pattern number writing / reading process shown in the flowchart of FIG. 8, the electronic control unit 20 stores the memory M (P) at a predetermined address in the pattern number storage area in the RAM 25 designated by the value of the combination pointer P. ), A process of storing the pattern number Nptn (mn) corresponding to the operated numeric keypad 13 (step 260), and then performing step 27
In the process of 0, an affirmative judgment is made that the message flag Fmsg is set. Next, at step 260, RA
The same pattern number Nptn (mn) stored in M25 is
The memory MEP (Ngr) at a predetermined address of the EEPROM 31 specified by the group number Ngrp and the value of the combination pointer P
A process (step 350) of writing in a nonvolatile manner to (p, P) is performed.

The display unit 9 displays the schematic shape of the pattern corresponding to the input number mn following the first message number Nmsg, as illustrated in FIG. 11F, by another process performed by the electronic control unit 20. I do.

In this way, the pattern number writing / reading process is once completed. However, after operating the "+" key 17 and operating the ten key 13 to input a number, the pattern number Nptn corresponding to the input number mn is obtained. (Mn) is stored in the memory M (P) at a predetermined address of the RAM 25 specified by the incremented combination pointer P, and the memory MEP () at a predetermined address of the EEPROM 31 specified by the group number Ngrp and the incremented combination pointer P N
grp, P) (step 350)
Perform

By the above operation, the RAM 25 and the EEP
The pattern numbers Nptn are stored in the ROM 31 in the order of input.

If the start / end key 15 is pressed again, in this case, in the pattern number writing start / end processing shown in FIG. 9, an affirmative judgment is made that the message flag Fmsg is set in the processing of step 330, and It is determined that the storage of the message pattern has ended, and the message flag Fms
The process of resetting g (step 360) is executed, and the writing of the pattern number ends.

As described above, after selecting the No. 95 to No. 99 with the ten keys 13 and pressing the start / end key 15, the operation of inputting the number with the ten keys 13 and pressing the "+" key 17 is repeated. When the start / end key 15 is pressed, the EEPROM 31 first stores 95
In the area of the group number Ngrp selected by inputting the numbers 99 through 99, the pattern numbers are arranged and written in the input order as shown in FIG.

As shown in FIG. 11 (G), the display unit 9 displays the message number Nmsg and the second pattern after the first pattern following the display of the first pattern by another process performed by the electronic control unit 20. Display the pattern.

(C) Next, the processing executed by the electronic control unit 20 in the operation pattern for forming the message pattern registered on the cloth in the processing of the operation pattern (a) will be described.

When a desired message pattern registered number is input from the 95th to 99th keys with the ten keys 13, the electronic control unit 20 starts the pattern number writing / reading process shown in FIG.

In the pattern number writing / reading processing, an affirmative determination is made in step 230 that the input number mn is 95th to 99th.

Next, a process of setting the input number mn as the message number Nmsg and a process of obtaining the value (mn-95) obtained by subtracting the value 95 from the input number mn as the group number Ngrp of the EEPROM 31 are performed.

When the group number Ngrp is obtained in this manner, the EEPROM 31 designated by the group number Ngrp
A process (step 300) of reading out a group (Ngrp) of the pattern numbers Nptn written in step (1) is performed.

Next, the group of the read pattern numbers Nptn is represented by R
A process (step 310) of developing the data in each memory M of the pattern number storage area in the AM 25 is performed. In this process, the pattern numbers Nptn constituting the group of the read pattern numbers Nptn are stored in the memory M (P) at the addresses designated in the RAM 25 in ascending order of the value of the combination pointer P from the head thereof.

Thereafter, as the value of the combination pointer P, the pattern numbers Nptn constituting the group of the read pattern numbers Nptn
Is performed (step 320), and the above processing ends.

As shown in FIG. 11 (G), the display unit 9 displays the input 95th to 99th numbers by a separate process performed by the electronic control unit, as in the case where the message pattern is stored. , Followed by E specified by this number
The pattern numbers Nptn of the group areas of the EPROM 31 and the arrangement of the schematic shapes of the corresponding patterns are displayed.

Here, when the start switch 7 is pressed, the electronic control unit 20 starts another processing for forming a pattern, and
The pattern numbers Nptn developed in M25 are read out in ascending order of the combination pointer P, and the read pattern numbers N
By reading the set of stitch data corresponding to ptn from the ROM 23 and driving the sewing mechanism of the sewing machine, the message pattern selected by the ten keys 13 is formed.

(D) The processing of the electronic control unit 20 has been described for each operation pattern.
The process executed by the electronic control unit 20 in the operation pattern for correcting the input of No. 3 will be described. In this operation pattern, a cancel key 19 is used.

When the cancel key 19 is pressed, the electronic control unit 20
Executes the pattern number cancellation process shown in FIG. In this process, first, a process (step 370) for determining whether or not the message number Nmsg is the value “FF” is performed.

If it is determined that the message number Nmsg is the value "FF", the state is the state described in the operation pattern (a), that is, neither the registration of the message pattern nor the reading of the message pattern. , A memory M at a predetermined address in the RAM 25 specified by the combination pointer P
(P) is cleared (step 380), and
Subsequently, a process of decrementing the combination pointer P (step 390) is performed, and this process ends.
As a result, only the last stored pattern number Nptn is RA
The process is canceled from M25, and the process returns to the state before inputting the pattern number.

On the other hand, if a negative determination is made in step 370 that the message number Nmsg is not the value "FF", then a determination process (step 400) as to whether or not the message flag Fmsg is set is performed.

The state where the message number Nmsg is not the value "FF" and the message flag Fmsg is set is the state where the message pattern described in the operation pattern (a) is registered.

In this state, the memory M (P) at a predetermined address of the RAM 25 designated by the combination pointer P is stored in the memory M (P) at the value "F
F ”(step 410), and
A process of setting the memory MEP (Ngrp, P) at a predetermined address of the EEPROM 31 designated by the group number Ngrp and the combination pointer P of the EPROM 31 to the value "FF" (Step 420) is executed. Thereafter, a process of decrementing the combination pointer P (step 430) is performed, and
This processing ends. Thereby, the RAM 25 and E
The pattern number Nptn last written in the EPROM 31 is canceled, and the process returns to the state before the pattern number was input.

On the other hand, the reason why the message flag Fmsg has not been set in the processing of the previous step 400 is negative is that, for example, the ten key 1 in the operation pattern (c).
In step 3, the message pattern is read and its contents are checked. However, in order to change the entire message pattern to form a different pattern, the pattern number developed in the RAM 25 is to be deleted.

In such a case, the process of setting the message number Nmsg to the value “FF” (step 440) and the process of setting the group number Ngrp to the value “FF” (step 450)
At the same time, and setting all the memories M in the pattern number storage area in the RAM 25 to the value "FF" (step 46).
0) and the process of setting the combination pointer P to the value "FF" (step 470). As a result, all the pattern numbers Nptn developed in the RAM 25 are erased. Depending on the cancellation of the pattern number Nptn in the RAM 25, EE
The arrangement of the pattern numbers Nptn stored in the PROM 31 is not deleted.

The processing based on the electronic control unit 20 shown in FIG. 10 including the operation of the cancel key 19 functions as the pattern erasure control means of the present invention.

In the sewing machine according to the embodiment described above, every time the pattern number of the pattern selected by the ten keys is stored in the RAM 25, the pattern number is also stored in the EEPROM 31, and the pattern number stored in the EEPROM 31 is used for the ten key operation. Can be expanded in the RAM 25, and the name and the like expected to be used again are used as a message pattern in the EE.
By registering the name in the PROM 31 and reading it out using the numeric keypad, there is an excellent effect that the registered name can be formed many times. Therefore, the labor of input is greatly reduced.

Each time a pattern is selected with the numeric keypad, E
Since the pattern number of the pattern is written in the EPROM 31,
Even if an erroneous operation such as turning off the power in the middle is performed, the selected pattern can be saved. In addition, EEP
By writing the pattern number in the ROM 31 for each selection,
The time required to write all the pattern numbers into the EEPROM 31 can be shortened compared to writing all the pattern numbers last, and the usability is improved.

Further, the pattern number of the message pattern is set to EE
Even when the data is stored in the PROM 31, if the start / end key is pressed, the RAM 2 described in the operation pattern (A) will be described.
5 is easy to handle because the operation may be performed in the same manner as the normal pattern selection procedure in which a pattern number is stored.

As described above, the sewing machine according to the embodiment can register a frequently used one such as a name as a message pattern, and can cope with an erroneous operation such as when the power supply is inadvertently turned off. In addition, there is an excellent effect that the usability of this type of sewing machine can be significantly improved, for example, the operation does not take much time and the operation is simple.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and can be implemented in various modes without departing from the gist of the present invention. Of course. For example, a configuration may be used in which the RAM is backed up by a battery as the nonvolatile storage means. The non-volatile storage means includes:
As in the embodiment, the pattern number may be stored every time a pattern is selected. However, after all the pattern numbers are selected, the arrangement of the pattern numbers stored in the RAM 25 is finally stored in the nonvolatile storage means. May be performed.

[0083]

As described in detail above, according to the sewing machine of the present invention, one or more selected patterns are stored in a nonvolatile storage means in a nonvolatile manner, and the patterns stored in a nonvolatile manner are stored. Can be read out and developed and sewn when a pattern is formed by a predetermined operation, so that the name etc. that is expected to be used again can be registered once and formed many times. It has an excellent effect that it becomes possible. Further, at the time of correcting the pattern to be selected and stored, the pattern erasure control means determines , based on the operation of the canceling means, that a single pattern is sequentially selected and the last pattern stored volatilely in the volatile storage means. Erase the pattern stored in
For a pattern group composed of a plurality of patterns stored in the nonvolatile storage means in a non-volatile manner in combination, if the pattern group is stored in the volatile storage means in a volatile manner, the pattern groups are collectively stored. Therefore, the pattern to be selected and stored can be easily corrected.
