Then, the control unit 100 reads the sewing data stored in the ROM 102 or the external storage device 104 by executing the predetermined control program by the CPU 101 at the time of sewing execution, so that the sewing machine motor 5 The X-axis motor 14 and the Y-axis motor 15 are driven so as to be the needle drop position indicated by the sewing data at the start of driving, so that the holding frame 11 is positioned on the sewing needle 8 (needle bar 8a). To control. Then, the CPU 101 drops the sewing needle 8 by positioning the holding frames 11 in order in a plurality of needle drop positions based on the coordinate data set in the sewing data while synchronizing with the rotation of the sewing machine motor 5. The control is continued until sewing is completed.

In addition, the control unit 100 reads screen information on the input setting screen and the like from the ROM 102 or the external storage device 104 at the time of inputting or confirming the setting of sewing data, and based on this. Control to display the input setting screen on the operation panel 20. In particular, the control part 100 functions as a part of display means which displays the coordinate data regarding sewing data on the display part 22. FIG.

For example, Fig. 4 is an example showing a setting screen of sewing data. In this setting screen, the operation key group 21 has an eight-direction input key 21a for moving the cursor C displayed on the display unit 22 in a desired direction, and coordinates related to the coordinates at which the cursor C is located. A deciding key 21b for confirming the data as a needle-point shape point of the sewing data, a needle dropping point, or the like is provided.

In addition, the display unit 22 includes a coordinate Q indicating the position of the cursor C, a needle stitch shape formed to connect a shape point (black point in the figure) or a needle drop point (gray point in the figure). It is supposed to be displayed. This "shape point" is a point for actually indicating the stitch-shaped line formed by sewing machine M. A plurality of shape points are input and set, and a desired stitch-like line is set as sewing data. Then, a plurality of needle drop points are set between the shape points according to the sewing pitch or the like. The coordinates indicating the positions of the cursor C, the shape point, the needle drop point, and the like are based on the holding frame 11 with respect to the cursor C, the shape point, the needle drop point, etc. with respect to the holding frame 11. In addition to indicating the position, the position data indicates the position of the sewing needle 8 with respect to the holding frame 11.

Then, as the eight-way input key 21a is inputted in such a setting screen, the cursor C of the display unit 22 is moved to display the coordinates Q (coordinate data) at which the cursor C is located. It is.

5 is an example showing the confirmation screen of sewing data. In this confirmation screen, the operation key group 21 has a cursor along the needle stitch shape which is formed to connect a shape point (black point in the figure) or a needle drop point (gray point in the figure) displayed on the display unit 22 ( A forward retreat key 21c for moving the C), a list key 21d for listing the coordinate data of the shape point and the needle dropping point relating to the currently displayed sewing data, and the like are provided.

Moreover, the display part 22 is made to display the coordinate R which shows the position of the needle C-shaped cursor C. As shown in FIG.

Then, as the forward retreat key 21c is inputted in such a confirmation screen, the cursor C of the display unit 22 moves along the needle stitch shape according to the sewing data, and the coordinate C where the cursor C is located; Coordinate data) is displayed. In the operation panel 20, the forward retraction key 21c of the operation key group 21 functions as designation means for designating coordinate data stored as sewing data.

In addition, the control part 100 controls as a judging means for judging whether the coordinate data of the sewing data input or specified through the operation panel 20 is included in the coordinate data group which is stored in the ROM 102 and is predetermined. Run

For example, the control unit 100 has the coordinate data corresponding to the coordinate (coordinate Q) at which the cursor C is moved as the eight-way input key 21a is inputted on the setting screen. Judgment as to whether or not (8) is included in the coordinate data group when located in the sewing-capable area inside the holding frame 11, or the cursor moved as the forward retraction key 21c is inputted in the confirmation screen. Whether coordinate data corresponding to the coordinate (coordinate R) where (C) is located is included in the coordinate data group when the sewing needle 8 is located in the sewable area inside the holding frame 11. Run the judgment on.

Specifically, for example, when the range of coordinate data when the sewing needle 8 is located in the sewing possible area inside the holding frame 11 is (X, Y) = (± 30, ± 30), Whether the X coordinate or the Y coordinate at the input coordinate Q or the specified coordinate R is within the range of the coordinate data group, such as -30 ≤ X coordinate ≤ +30, -30 ≤ Y coordinate ≤ +30 The control unit 100 executes the determination on.

Moreover, since the range of the coordinate data when the sewing needle 8 is located in the sewable area inside the holding frame 11 varies depending on the size of the holding frame 11, it is set for each holding frame 11, It is supposed to be remembered.

In addition, the controller 100 may or may not include coordinate data input or designated through the operation panel 20 based on the result determined by the determination means, in the coordinate data group corresponding to the sewable area. In accordance with this, control for displaying the coordinate data in another display form is executed.

Specifically, for example, when the coordinate data input through the operation panel 20 is included in the coordinate data group corresponding to the sewable area, the coordinates are displayed in black, and the coordinate data input through the operation panel 20 is displayed. Is not included in the coordinate data group corresponding to the sewable area, the coordinate data is displayed in another display form so that the coordinates are displayed in red.

Next, the processing operation at the time of setting the sewing data in the sewing machine M (the sewing machine main body 1) of the present embodiment will be described based on the flowchart shown in FIG.

First, as a predetermined key of the operation panel 20 is pressed, the sewing machine M is switched to an input mode for performing input setting of coordinate data relating to sewing data, so that the operation panel 20 may be, for example, illustrated in FIG. The setting screen as shown in 4 is displayed (step S101).

Next, the controller 100 determines whether the eight-way input key 21a of the operation panel 20 is pressed (step S102).

If the control section 100 determines that the eight-way input key 21a is pressed (step S102; Yes), the control section 100 sets the coordinate display flag F to F = 0 (step S103), and the eight-direction. According to the direction of the input key 21a, the parameter of the coordinate data of the cursor C is updated (step S104).

Next, the control unit 100 determines that the parameter of the X coordinate in the coordinate data of the cursor C input and updated by the operation of the eight-way input key 21a corresponds to a predetermined sewing possible area. It is determined whether it is in the range (e.g., -30? X? +30) (step S105).

If the control unit 100 determines that the parameter of the X coordinate in the coordinate data of the input cursor C falls within the range of the coordinate data group corresponding to the predetermined sewing area (step S105; Yes), the coordinate display flag (F) is set to F = F + 0 (step S106), and the flow advances to step S108.

On the other hand, when the control part 100 determines that the parameter of the X coordinate in the coordinate data of the input cursor C does not fall within the range of the coordinate data group corresponding to the predetermined sewing possible area (step S105; No), The coordinate display flag F is set to F = F + 1 (step S107), and the flow proceeds to step S108.

In step S108, the control unit 100 determines that the coordinate data group whose Y coordinate parameter in the coordinate data of the cursor C input and updated by the operation of the eight-way input key 21a corresponds to the predetermined sewing-capable area. It is determined whether or not to fall in the range of (e.g., -30? Y? +30) (step S108).

If the control unit 100 determines that the parameter of the Y coordinate in the coordinate data of the input cursor C falls within the range of the coordinate data group corresponding to the predetermined sewing possible region (step S108; Yes), the coordinate display flag (F) is set to F = F + 0 (step S109), and the flow proceeds to step S111.

On the other hand, if the control part 100 determines that the parameter of the Y coordinate in the coordinate data of the input cursor C does not fall within the range of the coordinate data group corresponding to the predetermined sewing possible area (step S108; No), The coordinate display flag F is set to F = F + 10 (step S110), and the flow advances to step S111.

In step S111, the controller 100 determines whether the coordinate display flag F is F = 0 (step S111).

If the control unit 100 determines that the coordinate display flag F is F = 0 (step S111; Yes), the control unit 100 displays both the parameters of the X coordinate and the Y coordinate in the coordinates of the inputted cursor C. It displays in black at the coordinate Q of 22 (step S112), and moves the cursor C. FIG.

Then, the holding frame 11 is moved in accordance with the coordinate data indicated by the cursor C (step S113), and the processing proceeds to step S115.

On the other hand, if the control unit 100 determines that the coordinate display flag F is not F = 0 (step S111; No), among the parameters of the X coordinate and the Y coordinate in the coordinates of the updated cursor C, The parameter not in the range of the coordinate data group corresponding to the predetermined sewing area is displayed in red at the coordinate Q of the display unit 22 (step S114), and the cursor C is moved. The flow then advances to step S115.

In step S115, the controller 100 determines whether or not the eight-way input key 21a of the operation panel 20 is pressed (step S115).

If the control part 100 determines that the eight-way input key 21a of the operation panel 20 is pressed (step S115; Yes), it returns to step S103.

On the other hand, if the control unit 100 determines that the eight-way input key 21a of the operation panel 20 is not pressed (step S115; No), the control unit 100 determines whether the predetermined coordinate memory key is pressed. (Step S116).

If the controller 100 determines that the coordinate memory key is not pressed (step S116; No), the control returns to step S115.

On the other hand, when the controller 100 determines that the coordinate memory key is pressed (step S116; Yes), the controller 100 causes the external memory device 104 to store the coordinate data of the input cursor C (step S117). .

Subsequently, the controller 100 determines whether or not the determination key 21b of the operation panel 20 is pressed (step S118).

If the control part 100 determines that the determination key 21b of the operation panel 20 is not pressed (step S118; No), it returns to step S102.

On the other hand, if the control unit 100 determines that the determination key 21b of the operation panel 20 is pressed (step S118; Yes), the coordinate data that has been input so far and stored in the external storage device 104 is synthesized. (Step S119), the input setting process of sewing data is completed.

In this way, the sewing machine M operates the eight-way input key 21a of the operation key group 21 of the operation panel 20 to move the cursor C, thereby corresponding to the coordinates at which the cursor C is located. , The coordinate data regarding the position where the sewing needle 8 falls to the cloth can be input, and sewing data can be created.

In particular, when the cursor C is moved by operating the eight-way input key 21a, whether the coordinate where the cursor C is located corresponds to the sewable area inside the holding frame 11 is sewn. According to whether or not it is included in a predetermined coordinate data group for a possible area, the display color of the display panel 22 (coordinate Q) of the operation panel 20 is different from the parameter of the coordinate data at which the cursor C is located. And other display forms.

That is, the parameter of the coordinate data of the cursor C displayed on the display unit 22 is red, etc., to indicate that the coordinate data other than the sewable area is not included in the coordinate data group predetermined for the sewable area. If it is displayed in the warning color, it is determined that sewing with the coordinate data cannot sew the desired needle stitch shape.

Then, black indicating that the parameter of the coordinate data of the cursor C displayed on the display unit 22 in a warning color such as red is included in the coordinate data group predetermined for the sewing possible region as coordinates in the sewing possible region. By moving the cursor C based on the display form (display color) of the parameter to the position indicated by, the coordinate data at the coordinates where the cursor C is located is stored and registered as sewing data more reliably. In the sewing machine M, sewing data valid for sewing can be created.

In this manner, the sewing machine M can easily display whether or not the coordinate data of the sewing data relating to sewing is valid data for the execution of the sewing.

Next, the processing operation at the time of confirming the coordinate data of the sewing data in the sewing machine M (the sewing machine main body 1) of this embodiment is demonstrated based on the flowchart shown in FIG.

First, as a predetermined key of the operation panel 20 is pressed, the sewing machine M enters a confirmation mode for confirming coordinate data relating to sewing data, and the operation panel 20 is shown in, for example, FIG. 5. A confirmation screen as shown is displayed (step S201).

Next, the control part 100 determines whether the forward retraction key 21c of the operation panel 20 was pressed (step S202).

If the control section 100 determines that the forward retraction key 21c has been pressed (step S202; Yes), the control section 100 sets the coordinate display flag F to 0 (step S203), and the forward retraction key. The cursor C is moved along the needle stitch shape in the direction of 21c, and the parameter of the coordinate data of the cursor C is updated (step S204).

Subsequently, the control unit 100 determines that the parameter of the X coordinate in the coordinate data of the cursor C specified and updated by the operation of the forward retreat key 21c is within the range of the coordinate data group corresponding to the predetermined sewnable area. It is determined whether to lift (for example, -30? X? +30) (step S205).

If the control unit 100 determines that the parameter of the X coordinate in the coordinate data of the designated cursor C falls within the range of the coordinate data group corresponding to the predetermined sewing possible area (step S205; Yes), the coordinate display flag ( F) is set to F = F + 0 (step S206), and the flow proceeds to step S208.

On the other hand, if the control unit 100 determines that the parameter of the X coordinate in the coordinate data of the specified cursor C does not fall within the range of the coordinate data group corresponding to the predetermined sewing possible region (step S205; No), the coordinates The display flag F is set to F = F + 1 (step S207), and the processing proceeds to step S208.

In step S208, the control unit 100 determines that the parameter of the Y coordinate in the coordinate data of the cursor C specified and updated by the operation of the forward retreat key 21c corresponds to the predetermined stitchable area. It is determined whether it is in the range (e.g., -30? Y? +30) (step S208).

If the control unit 100 determines that the parameter of the Y coordinate in the coordinate data of the designated cursor C falls within the range of the coordinate data group corresponding to the predetermined sewing possible area (step S208; Yes), the coordinate display flag F ) F = F + 0 (step S209), and the process proceeds to step S211.

In step S211, the controller 100 determines whether the coordinate display flag F is F = 0 (step S211).

If the control unit 100 determines that the coordinate display flag F is F = 0 (step S211; Yes), the control unit 100 displays both the parameters of the X coordinate and the Y coordinate parameter in the coordinates of the designated and updated cursor C. 22 is displayed in black at the coordinates R (step S212), and the holding frame 11 is moved in accordance with the coordinate data indicated by the cursor C (step S213), and the process proceeds to step S215.

On the other hand, if the control unit 100 determines that the coordinate display flag F is not F = 0 (step S211; No), among the parameters of the X coordinate and the Y coordinate parameter in the coordinates of the designated and updated cursor C, The parameters that do not fall within the range of the coordinate data group corresponding to the predetermined sewing area are displayed in red at the coordinates R of the display unit 22 (step S214). The flow then advances to step S215.

In step S215, the controller 100 determines whether or not the forward retraction key 21c of the operation panel 20 is pressed (step S215).

If the control part 100 determines that the forward retraction key 21c of the operation panel 20 is pressed (step S215; Yes), the control returns to step S203.

On the other hand, if the control unit 100 determines that the forward retraction key 21c of the operation panel 20 is not pressed (step S215; No), the control unit 100 determines whether or not the predetermined confirmation end key is pressed ( Step S216).

If the control part 100 determines that the confirmation end key of the operation panel 20 is not pressed (step S216; No), it returns to step S215.

FIG. ), The coordinate data regarding the position where the sewing needle 8 falls to the cloth can be selected, which corresponds to the coordinates of the shape point where the cursor C is located or the coordinate of the needle dropping point.

In particular, when the cursor C is moved by operating the forward retraction key 21c, whether the coordinate where the cursor C is located corresponds to the sewable area inside the holding frame 11 can be sewn. According to whether or not it is included in a predetermined coordinate data group for an area, the display color 22 of the operating panel 20 changes the display color parameter of the coordinate data at which the cursor C is located. And other display forms.

That is, the parameters of the coordinate data of the cursor C displayed on the display unit 22 are coordinates other than the sewnable area and are not included in the coordinate data group predetermined for the sewable area. When it is displayed in the warning color, it is determined that sewing with the coordinate data cannot sew the desired needle stitch shape.

Then, the coordinate data parameter of the cursor C, which is displayed in a warning color such as red, is a position in black indicating that the parameter in the sewnable area is included in the coordinate data group predetermined for the sewable area. The position of the coordinate can be corrected by moving the cursor C based on the display form (display color) of the parameter. By storing and registering the new coordinate data at the coordinate where the cursor C is located as sewing data, the sewing data (coordinate data) is corrected, and as sewing data effective for sewing in the sewing machine M. I can write it.
