DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine, and more particularly, to selecting a pattern from storage means storing a plurality of patterns.
The present invention relates to a sewing machine that stores a sequence of one or more selected patterns, sequentially reads out the stored sequence of patterns, drives a sewing mechanism of the sewing machine, and forms a pattern.

[0002]

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.

The electronic control unit 20 executes a program stored in the ROM 23 to perform a pattern selecting process, a pattern forming process, and the like in accordance with an instruction from the numeric keypad 13 and the like. , ROM2
3, predetermined areas of the RAM 25 and the EEPROM 31 are respectively assigned to specific data structures.

In the ROM 23, stitch data for driving the motor driving device 39 and the actuator driving device 45 to form a pattern is stored in advance for each pattern. In this area, as shown in FIG. 4A, stitch data necessary to form one character or symbol is collected into one set, and the entire set of stitch data is represented by one pattern number Nptn. It is configured to the specified structure.

A pattern number storage area for storing the pattern number Nptn is set in the RAM 25. The pattern number storage area has a structure in which pattern numbers Nptn are stored side by side as shown in FIG. 4B, and each pattern number Nptn is specified by the value of the combination pointer P.

In the EEPROM 31, an area for storing the arrangement of the pattern numbers Nptn in a nonvolatile manner is set. As shown in FIG. 4C, the area has a structure in which a group in which pattern numbers Nptn are arranged is collectively stored for each group, and the group is specified by a group number Ngrp. The group in which the pattern numbers Nptn stored here are arranged corresponds to the arrangement of the pattern numbers Nptn stored in the RAM 25. In the embodiment, the group numbers Ngrp are provided from No. 0 to No. 4, and the group of the pattern numbers Nptn is 5
Set is 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 this embodiment, 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 initial processing is performed, the electronic control unit 20 performs the pattern selection processing shown in the flowchart of FIG. 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), first, the operation key
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. Hereinafter, the processing performed by the electronic control unit 20 will be described according to the operation pattern.

(A) First, a process performed by the electronic control unit 20 in an operation pattern for forming a required pattern 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 keys 13 are operated,
The electronic control unit 20 determines that the operation key is the ten key 13 in the process of step 110, and proceeds to step 120.
, Ie, the 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. 2
When the digit input number mn is specified, a process of determining whether or not the "+" flag Fpls is set (step 21)
Perform 0). When the ten key 13 for inputting the first pattern is operated, the "+" flag Fpls is not set, so a negative judgment is made in the process of step 210.
A process (step 220) of resetting the combination pointer P to the value “FF” is executed. The combination pointer P designates the combination order of the pattern number Nptn of the pattern corresponding to the input number mn.

Next, a determination process (step 230) is performed to determine whether or not the input number mn is in the range of 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 stitch data in the ROM 23 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 in 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 of determining whether or not the message flag Fmsg is set (step 270) is performed.
The message flag Fmsg is set or reset in the subroutine of step 140 by operating the start / end key 15. To enter the pattern arrangement only once, the message flag F
Since msg has been reset, a negative determination is made in the process of step 270, and the above pattern number writing / reading process is temporarily terminated.

In this way, the pattern number Nptn of the pattern input by the operated numeric keypad 13 is stored in the RAM 25, and 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 at the beginning for several seconds as illustrated in FIG. 9A, and then displays a pattern corresponding to the input number mn as illustrated in FIG. 9B. 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 the processing of step 150. The electronic control device 20 displays a “+” sign on the display unit 9 following the display of the leading pattern as illustrated in FIG. 9C by another process.

Thereafter, when the ten key 13 is operated, the electronic control unit 20 executes the pattern number writing / reading process 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 the memory M (P) at a predetermined address in the pattern number storage area in the RAM 25 designated by the incremented combination pointer P (step 260).
The calculated pattern number is stored after the previous pattern number. In the process of step 270, since the message flag Fmsg has been reset, a negative determination is made, and the above process 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 order of input as shown in FIG. In the display unit 9, the electronic control unit 20 displays the schematic shape of the second input pattern after the first pattern display instead of the “+” symbol display as illustrated in FIG. I do.

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 number Nptn stored side by side in each memory M of the pattern number storage area in the RAM 25 is used as a combination pointer P
From the ROM 23, and read out a set of stitch data corresponding to the read pattern number Nptn from the ROM 23,
By driving the sewing mechanism of the sewing machine, 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 the input number m is entered as the message number Nmsg
A process for setting n (step 280) 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 way, the EEPROM 31 designated by the group number Ngrp
A process (step 300) for reading out a group (Ngrp) of pattern numbers Nptn that has already been written in the area within the area is performed. Subsequently, the group of read pattern numbers Nptn is stored in RAM2.
5 (step 310), and 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). Is performed, and the process is temporarily terminated.

Even if the processes of steps 280 to 320 are 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.

As described above, the number keys 95 to 9 are set with the ten keys 13.
When the number 9 is input, processing for setting the message number Nmsg is executed.
Performs display processing, and displays a message number Nmsg at the top of the display unit 9 as illustrated in FIG. 9E. This display confirms that the operation mode is the mode of the process related to the message pattern.

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, as shown in FIG. 7A, first, a determination process (step 330) as to whether or not the message flag Fmsg is set is performed. Since the message flag Fmsg is not set when the number 95 to 99 is input with the ten keys 13, a negative determination is made in the processing of step 330, and it is determined that the storage of the message pattern is to be started. A process for setting the flag Fmsg (step 340) is performed.

The electronic control unit 20 repeatedly executes the processing shown in the flowchart of FIG. 8 in the display processing performed together with the execution of the above processing. In this process, first,
A process (step 500) for determining whether or not the message flag Fmsg is set is performed. After the start / end key 15 has been pressed, it is determined that the message flag Fmsg has been set. Therefore, a process of setting a flag Frev for inverting the message number Nmsg displayed on the display unit 9 (step 510). Is performed, and the process is temporarily terminated. When the inverted display flag Frev is set in this way, the electronic control unit 20 executes the display process (not shown) to reverse the display of the message number Nmsg on the display unit 9 as shown in FIG. 9 (F).

As described above, when the numbers 95 to 99 are input with the ten keys 13 and the start / end key 15 is pressed, the display of the message number Nmsg on the display unit 9 is highlighted. Since the display of the message number Nmsg is highlighted, the selection mode changes the pattern number Nptn of the selected pattern to E.
It is confirmed that the mode is for writing to the EPROM 31. Thereafter, similarly to the pattern combination operation described in the operation pattern (A), the ten keys 13 and the "+" key 17 are alternately and repeatedly operated, and the RAM 25 and the EEPROM are operated.
31 stores the pattern numbers Nptn corresponding to the input numbers mn in the order of input.

That is, in the pattern number writing / reading process shown in the flowchart of FIG. 6, 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.

As shown in FIG. 9 (G), the display unit 9 displays the input number mn following the message number Nmsg displayed at the top by another process performed by the electronic control unit 20, as shown in FIG.
Is displayed. In this way, the pattern number writing / reading process is temporarily terminated. However, if the number is input by operating the ten key 13 after operating the “+” key 17, the pattern number Nptn (m) corresponding to the input number mn is obtained.
n) is stored in the memory M (P) at a predetermined address of the RAM 25 designated by the incremented combination pointer P, and the EEPROM 31 designated by the group number Ngrp and the incremented combination pointer P
Is performed in a nonvolatile manner (step 350) in the memory MEP (Ngrp, P) at the predetermined address.

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. As shown in FIG. 9H, the display unit 9 performs the second input after the reverse display of the message number Nmsg and the subsequent display of the first input pattern by a separate process performed by the electronic control unit 20. Display of the changed pattern.

Here, if the start / end key 15 is pressed again, in the pattern number writing start / end processing shown in FIG. 7A, in this case, the message flag Fmsg is set in the processing of step 330. An affirmative determination is made, and it is determined that the storage of the message pattern has been completed, and the message flag Fmsg is reset (step 360).
And the writing of the pattern number ends.

When the storage of the message pattern is completed, the electronic control unit 20 executes the display processing shown in the flowchart of FIG. In this case, it is determined in step 500 that the message flag Fmsg is not set, and a process of resetting the reverse display flag Frev (step 520) is performed. Accordingly, the electronic control unit 20 switches the display of the message number Nmsg from the reverse display to the normal display as shown in FIG.

As described above, after selecting the No. 95 to No. 99 with the ten keys 13 and pressing the start / end key 15, the message number Nmsg on the display unit 9 is highlighted.
That is, the pattern number Nptn selected by the selection mode is added to the EEPROM.
After confirming that the mode is the writing mode to the M31, the operation of inputting the number using the numeric keypad 13 and the operation of pressing the “+” key 17 are repeated. At 95
As shown in FIG. 4C, pattern numbers Nptn are arranged and written in the area of the group number Ngrp selected by inputting the numbers 99 through 99. Finally, when the start / end key 15 is pressed, the message pattern writing mode described above is ended. (C) Next, in the operation pattern for forming the message pattern registered in the processing of the operation pattern (a) on the cloth, The processing executed by the electronic control unit 20 will be described.

When a desired message pattern registered number is input from number 95 to number 99 using 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 process, 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 pattern number Npt written in the EEPROM 31 designated by the group number Ngrp
A process (step 300) for reading out a group of n (Ngrp) is performed.

Next, the group of 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. 9 (I), the display unit 9 performs the display processing performed by the electronic control unit 20 in the same manner as in the case where the message pattern is stored.
The message numbers Nmsg from No. 99 to No. 99 and the pattern numbers Nptn stored in the group area Ngrp of the EEPROM 31 designated by the message number Nmsg number and the outline of the corresponding pattern are successively displayed.
In this case, the display of the message number Nmsg is not inverted because the process has finished writing the pattern number of the message pattern. Therefore, it is confirmed that the selection mode is a mode relating to the message pattern, but is not a writing mode.

When the start switch 7 is pressed, the electronic control unit 20 starts another processing for forming a pattern, and
Pattern number Npt developed in the pattern number storage area in M25
n are read out in ascending order of the combination pointer P,
By reading the stitch data of the set corresponding to the read pattern number Nptn 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 a pattern number canceling process shown in FIG. In this process, first, the message number Nmsg
Is a value "FF" (step 37)
Perform 0).

If the message number Nmsg is affirmatively determined to be the value "FF", this 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 process of clearing the memory M (P) at a predetermined address in the pattern number storage area in the RAM 25 specified by the value of the combination pointer P (step 380), and then decrementing the combination pointer P (step 380) 390)
This processing ends. As a result, only the last stored pattern number Nptn is canceled from the RAM 25, and
It 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) is performed to determine whether or not the message flag Fmsg is set. The state where the message number Nmsg is not the value “FF” and the message flag Fmsg is set is a state where the message pattern described in the operation pattern (a) is registered.

In this state, the memory M (P) at a predetermined address in the pattern number storage area in the RAM 25 specified by the value of the combination pointer P is set to the value "FF" (step 41).
0), and the EEPROM designated by the group number Ngrp and the combination pointer P of the EEPROM 31.
The memory MEP (Ngrp, P) at the predetermined address of M31 is stored in the memory with the value "F
F ”(step 420). Thereafter, the process of decrementing the combination pointer P (step 430) is performed, and this process ends. As a result, the pattern number Nptn last written in the RAM 25 and the EEPROM 31 is canceled, and the process returns to the state before the input of the pattern number.

On the other hand, the reason why the judgment at step 400 is that the message flag Fmsg is not set is negative, for example, when the ten key 1 is used in the operation pattern (c).
The message pattern is read out in step 3 and the 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. Nms
g to the value “FF” (step 440) and the group number Ngrp to the value “FF” (step 45).
0), the process of setting all the memories M in the pattern number storage area in the RAM 25 to the value "FF" (step 460), and the process of setting the combination pointer P to the value "FF" (step 470). Perform Thereby, RAM2
The pattern numbers Nptn developed in the pattern number storage area in 5 are all deleted. The pattern number Npt of the RAM 25
By the cancellation of n, the arrangement of the pattern numbers Nptn stored in the EEPROM 31 is not erased.

The sewing machine of the embodiment described above is
After confirming the reverse display of the message number Nmsg in, the pattern is selected with the ten keys 13 and the pattern number Nptn is stored in the EEPROM 31 every time the pattern is selected.
The pattern number Nptn stored in the PROM 31 is stored in the RAM 2
Since it can be developed into 5 to form a pattern arrangement,
If the names and the like that are expected to be used again are stored in the EEPROM 31 as a message pattern and are read out using the numeric keypad, an excellent effect is obtained in that the stored names can be formed many times. Therefore, the labor of input is greatly reduced.

The mode difference between the case where the operation relating to the message pattern is performed and the case where the one-time pattern selection operation is performed is confirmed by whether or not the message number is displayed. When writing the pattern number of the message pattern in the EEPROM 31
The difference between the mode and the case where the message pattern number of the message pattern is read out is determined by whether the display of the message number is inverted or the normal display that is not inverted. However, erroneous operations such as not storing the pattern number in the EEPROM 31 or inputting the message pattern even when the message pattern is read out can be eliminated, and the effect that the usability can be improved can be achieved. Then, the message pattern is stored in the EEPROM 31.
To move to the state where the number is written,
The user only needs to enter the 99th number,
There is no need to perform any operations.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, a configuration may be used in which the RAM is backed up by a battery as the nonvolatile storage means. The pattern number may be stored in the nonvolatile storage means every time a pattern is selected as in the embodiment. However, after all the patterns are selected, the arrangement of the pattern numbers stored in the RAM 25 is finally stored in the nonvolatile storage. A configuration for performing processing for storing in the means may be used. With this configuration, if an erroneous operation such as turning off the power is performed halfway, the pattern numbers of all the selected patterns will not be stored in the non-volatile storage means, but a display indicating that the selection mode is the writing mode is displayed. If done, this kind of erroneous operation is greatly reduced, and the effect of invalidating the selected pattern can be effectively eliminated.
