DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 and 2, portions common or corresponding to those in FIGS. 6 and 7 of the conventional example are denoted by common reference numerals, and description of the common portions is omitted.

FIG. 1 shows an embodiment of the overall configuration of a sewing apparatus or a sewing system according to the present invention.
In addition to the above configuration, a personal computer (hereinafter abbreviated as PC) 31 is provided, and this PC 31 is connected to the control box 3 via a serial cable 32.

As shown in detail in FIG. 2, the PC 31 controls the entire system and performs various arithmetic processing and information processing.
U310, FDD 311 as external storage device and HD
D315, serial port 312, input device 313 such as keyboard and mouse, CRT display 314 as display means, RAM 316 and ROM 31 of memory
ROM 3 as initial value storage means.
17 stores, for each type of the sewing machine head 1a, an initial setting value of the sewing parameter at the time of shipping the sewing machine. Further, the ROM and RAM of the memory used by the CPU 22 of the control box 3 (25 and 2 of the conventional example in FIG.
6 are common to the CPU 22 and are not shown.

The PC 31 is connected to the CPU 22 of the control box 3 via a serial cable 32.
The first CPU 310 and the CPU 22 of the control box 3 exchange data with each other by serial communication (for example, communication by an RS-232C interface) via the serial port 312 and the serial cable 32.

In the present invention, in addition to setting various sewing parameters by operating the sewing machine setting means 27 (setting switch 9) or the operation panel 6, for example, a sewing parameter setting change program stored in the HDD 315 or the like is activated to start sewing. Parameters can be changed. This operation will be described with reference to FIGS.

When the sewing parameter setting change program is started, a setting screen as shown in FIG.
Appear on 4 When the read button 50 is operated, P
A request for transmission of a set value (setting information) of a sewing parameter is made from the C31 to the CPU 22 of the sewing machine via the serial communication, and the CPU 22 responds to the transmission request and transmits the set value stored in the nonvolatile memory 29 to the head. 1a and the currently set sewing parameter values of the sewing machine are sent to the PC 31, whereby the set values are read into the PC 31 (step S1).
316 (step S2).

Subsequently, the set values of various sewing parameters of the sewing machine are displayed on the parameter setting information display section (display means) 5 in FIG.
2 is displayed. This display is performed as follows.

First, the type of the head 1a set in the control box 3 is determined based on the setting information of the type of the head 1a included in the read set value (step S3).
After the parameter number is set to 1 (step S4), the initial setting value of the sewing parameter corresponding to the type of the head 1a is read from the ROM 317 and compared with the current sewing parameter setting value stored in the RAM 316 (step S4).
5) It is determined whether the initial set value is different from the current set value (step S6). If they are different, the current setting value is displayed with a green background color in the setting value column 58 of the parameter setting information display section 52 (step S7). (Step S
8).

In the above processing, the parameter number is incremented by 1 (step S10), and the processing is repeated until the last parameter number is reached (Yes in step S9).

The set value read in this way is N
In the order of the parameter numbers displayed in the o column 56, they are shown in the set value column 58 together with the contents 57 of the sewing parameters. For example, since the current setting value of the number of soft start stitches of No. 1 is the same as the initial setting value, 3 [Stitchc]
h] Data 59 is displayed with a gray background,
6 is different from the initial set value.
4 "OFF" is displayed with the background color being green. Since the sewing machine is a lockstitch sewing machine, it is displayed in the display column 55.

As described above, when the set value is different from the initial set value, the background color is changed and displayed so as to be identifiable, so that it is possible to see at a glance which sewing parameter set value has been changed from the initial set value. If there is a problem due to a setting error, the location of the setting error can be easily specified.

Next, the flow for changing the set values of the sewing parameters of the sewing machine will be described with reference to the flowchart of FIG.

To change the set value (step S2
1) By operating the selection button 60 on the setting change screen in FIG. 3, the number of the sewing parameter whose setting value is to be changed is selected (step S22). The selected number is displayed on the display unit 63, and the display unit 62 displays a plurality of selectable set values corresponding to the number.
In the example of FIG. 3, No. 3 is displayed on the display unit 63, and the set values of the sewing parameters, “OFF” and “ON”, are displayed on the display unit 62. The selection is made with the sewing parameter contents 5
7 can also be selected directly.

Here, the operator sets the set value to “OF”.
Since it is desired to change from “F” to “ON”, when “ON” is selected, the changed data is obtained (step S2).
3) The acquired setting values are displayed on the display unit 61.

When the selection button 60 is further operated, the parameter number is changed and the changed contents are cleared. Therefore, by repeating steps S22, S23 and S24, an arbitrary parameter number can be selected and the set contents can be obtained. .

The above processing is repeated until the setting change is determined and the enter button 64 is pressed. Step S25
When the determination button 64 is pressed, it is determined whether or not the content of the setting value acquired in step S23 has been changed and different from the previous setting value (step S26). If different, the changed setting value is displayed with the background color of the set value display column (eg, 53 in FIG. 3) set to red (step S27), and if not changed, the background color is left as it is. Is displayed (step S28).

Since the changed set values are displayed in different display forms so as to be identifiable, the operator can surely identify the parameter contents to be changed and the set values, thereby preventing a mistake in changing the set values. can do.

When the setting change is completed, the write button 51 of FIG. 3 is operated (step S29), and all the set values of the sewing parameters set on the parameter setting information display section 52 (information of the changed set values) Is transmitted to the sewing machine (step S30), and the CP of the sewing machine is transmitted.
U22 writes the received information on the set values of the various sewing parameters in the nonvolatile memory 29.

Subsequently, the CPU 22 of the sewing machine automatically reads out the setting information of various sewing parameters written in the nonvolatile memory 29 immediately and transmits the data to the PC 31. Upon receiving this, the CPU 310 of the PC 31 performs the processing of steps S1 to S10 in FIG.
The set values of the sewing parameters are displayed on the display unit 52. At this time, if the set value is the same as the initial set value, the background color is displayed in gray, and if different, the background color is displayed in green.

In this way, when the set value of the desired sewing parameter is changed from the initial set value, the operator can confirm whether or not the changed content has been reliably set on the sewing machine.

Instead of comparing the sewing parameters read into the PC 31 with the initial set values as described above, the sewing parameters before the change are stored in the PC 31 and the sewing parameters before the change are read. A configuration is also conceivable in which it is possible to always identify the previous set value as compared with the sewing parameter thus set. However, in this case, PC3
1 needs to store all the setting values of the sewing parameters set in the sewing machine connected before.
Even if it is stored, it is necessary to identify the connected sewing machine by some means. Moreover, if the change is repeated many times, there is a problem that the previous set value cannot be determined. However, if configured as in the present invention, the PC 31
Does not need to store past data and only needs to store an initial setting value corresponding to the model of the sewing machine. Therefore, there is no need to connect a PC specified to the sewing machine, and a simple configuration is possible. This can prevent setting errors.

In the case of displaying a set value different from the initial set value in an identifiable manner or displaying a changed set value in an identifiable manner, in the above-described embodiment, the background color is changed. Should be different from each other in display form, for example, the font and size of the character indicating the setting value can be different, the character can be highlighted or blinking, the character color can be different Other display modes may be used, such as changing the thickness or color of the display frame of the set value, or combining these display modes. Further, in the No. column (56 in FIG. 3) and the parameter content column (57 in FIG. 3), an identifiable display similar to that for the set value may be performed. Further, any one of the No. column, the set value column, and the parameter content column, or a dedicated column is separately provided, and a special code (for example, "*") is attached to the column for identification. Is also good.

In the above-described embodiment, the control box 3 and the PC 31 are connected by the serial cable 32. However, the control box 3 and the PC 31 may be connected via a LAN (local area network) or the Internet.

Further, in the above-described embodiment, the sewing machine and the P
Although the C31 is provided separately, a dedicated device having a function of displaying and changing the setting information of the sewing parameter of the sewing machine of the PC 31 may be provided integrally with the sewing machine.

Also, as in the above-described embodiment, the PC 3
1 is stored in another area of the non-volatile memory 29 instead of the initial setting value of the sewing parameter.
A setting device, or a setting device 27 and a setting device 28,
The above-described sewing parameters may be set and displayed.

In the above embodiment, the setting value changed by the change means is stored in the set value storage means by operating the write button. However, even if no write button is provided, the setting value is displayed by the change means. At the same time when the set value is changed, the set value may be stored in the set value storage means so that the sewing operation of the sewing machine can be performed based on the changed set value.

[0050]

As is apparent from the above description, according to the present invention, it is determined whether or not the set value of the sewing parameter is different from the initial set value, and the result of the determination is displayed in an identifiable manner. The operator can easily determine the location of a mistake in changing the set value of the sewing parameter, and the mistake can be easily corrected.

Further, according to the present invention, when the set value of the sewing parameter is changed, it is determined whether or not the changed set value is different from the set value before the change, and the result of the determination is identifiably displayed. With this configuration, it is possible to check at a glance which sewing parameter set value has been changed by the operator, and it is possible to prevent a mistake in changing the set value.

Further, in the present invention, after changing and storing the set value of the sewing parameter, it is automatically read out, and it is determined whether or not the set value is different from the initial set value. Therefore, it is possible to confirm whether or not the changed content has been securely set in the sewing machine.
