Next, the operation of the present invention will be described with reference to the flow charts shown in FIGS. In FIG. 2, S
When the pattern is selected in 1, the display data is read out from the pattern display data storage means 4 in S2 and S3 and displayed on the display device 2, and the sewing data of the selected pattern is stored in the selected pattern storage means 6.

Then, when the cloth display key 19 is operated,
The embroidery frame E holding the cloth is moved to an initial setting position corresponding to the cloth display device DP arranged in the middle of the arm of the sewing machine, and the cloth color or brightness detecting means 2
7 operates to read the color of the fabric and determine the opposite color data. In S8 to S9, the read display color data and the cloth data in the pattern display data are read and output to the light transmissive display device 20, and the display light source 21 is turned on to sew the embroidery pattern on the cloth. A square contour consisting of a width and height consisting of four lines of the direction reference underline, the embroidery pattern sewing start line, the embroidery pattern sewing end line and the embroidery pattern sewing direction reference upper line is displayed.

Subsequently, when the figure deformation instruction means 15 is operated, the figure transformation mode is set in S11, and the figure transformation is performed by the subroutine shown in FIG.

In S101 of FIG. 3, if a new magnification is selected as a new magnification, S10 is selected.
At 2, a plurality of graphic deformation patterns are displayed on the display device 2 in a selectable manner, and a desired change pattern is selected by operating the touch panel 1a.

At this time, in S103, the pattern state of the rectangular contour of the four lines is selectably displayed. When this is selected, the input instruction display of the sewing direction reference underline is displayed on the display device 2 in S105. When the sewing direction reference underline is changed, the Y direction manual operation key 18 is operated to output an operation signal.
Here, there are roughly two methods for correcting the display and sewing data with respect to the operation signal in the case of changing.

First, as a first method, there is a method of driving the X-direction control stepping motor 11 and the Y-direction control stepping motor 12 without moving the display position to move the cloth and align the changed position. . Although many operations are required for this purpose, the actual movement amount of the stepping motor can be set, so that there is little error and accurate alignment can be performed.

In S102 of FIG. 3, a plurality of graphic deformation patterns are displayed on the display device 2 in a selectable manner, and a desired deformation pattern is selected by operating the touch panel 1a.

When a 4-line rectangular contour pattern is selected in S103, a message is displayed on the display device 2 for inputting the sewing direction reference underline and the sewing direction reference on the cloth is selected in S105. Since the underline blinks and is movably displayed, in the case of changing the sewing direction reference underline, in S106, the Y direction manual operation key 18 is operated with respect to the display to output an operation signal. The Y direction control stepping motor 12 is driven in response to the signal,
When the decision frame 34 is operated when the cloth frame is moved to the desired height position on the displayed sewing direction reference underline and the desired position coincides with the displayed sewing direction reference underline, the instruction ends. Then, in S107, the movement amount from the reference value is stored in the calculation display data storage means 25 and the calculation sewing data storage means 26 as the display data and the change value of the sewing data as the sewing direction reference underline change data, The data is output to the light transmissive display device 20 and changed and displayed. Next, the Y-direction control stepping motor 12 is driven to return the cloth frame by the amount of the movement, and the desired reference underline and the display reference underline coincide with each other.

At S108, the input instruction display of the start line is displayed on the display device 2 and the start line on the cloth blinks so as to be movable. Therefore, when changing the start line, In S109, each of the X-direction manual operation keys 17 is operated to output an operation signal. The X-direction control stepping motor 11 is driven in response to the signal,
Move the cloth frame to the displayed start line of sewing. When the confirmation key 34 is operated at the desired position, it is determined that the instruction has been completed, and in S110, the movement amount from the initial setting position is used as the deformation data, the display data, and the calculated display data as the reference value of the sewing data. The data is stored in the storage means 25 and the arithmetic sewing data storage means 26, and output to the light transmissive display device 20 for change display. Here, if you do not change the start line,
The initial position is set by operating the enter key 34.

Next, in S111, the input instruction display of the end line is displayed on the display device 2 as a message, and the end line on the cloth blinks so as to be movable. In S112, the X-direction manual operation key 17 is operated with respect to the display to output an operation signal. In response to the signal, the X-direction control stepping motor 11 is driven to move the cloth frame to the end line of the displayed sewing.

When the confirmation key 34 is operated when the desired position coincides with the end line of the display, it is determined that the instruction is completed, and in S113, the movement amount from the reference value is set as the end line deformation data. As a modified value of the display data and the sewing data, it is stored in the arithmetic display data storage means 25 and the arithmetic sewing data storage means 26, and is output to the light transmissive display device 20 for change display. Further, the ratio of the modified data to the standard data is calculated and displayed on the display device 2 as the lateral magnification 2a.

Next, the X-direction control stepping motor 11 is driven to return by the movement adjustment amount to move the cloth frame and return it to a position where the desired start line and the display start line coincide. Since the display end line has already been changed, the desired end line position coincides with the display end line.

Next, in S114, the input instruction display of the sewing direction reference upper line is displayed on the display device 2 and the sewing direction reference upper line blinks so as to be movable. When changing, in S115, the Y direction manual operation key 1 with respect to the display
8 is operated to output an operation signal. In response to the signal, the Y-direction control stepping motor 12 is driven to move the cloth frame until the sewing direction reference upper line at the display height position coincides with the desired height position. When the confirmation key 34 is operated at the position where the direction reference upper line is matched, it is determined that the instruction is completed, and in S116, the movement amount from the reference value is used as the height position deformation data, and the display data and the sewing data are transformed. The values are stored in the calculation display data storage means 25 and the calculation sewing data storage means 26 and output to the light transmission display device 20 for change display. Further, the ratio of the modified data to the standard data is calculated, and the display device 2
The vertical magnification is displayed as 2b.

Next, the Y-direction control stepping motor 12 is driven to return and move the cloth frame by the amount corresponding to the movement of the cloth frame, and return to the position where the underline position of the desired sewing direction reference and the displayed sewing direction reference underline match. Since the sewing direction reference upper line has already been changed, the sewing direction reference upper line at the desired height position matches the displayed sewing direction reference upper line.

From this state, the Y direction control stepping motor 12 is again driven by the amount of movement to return to the sewing direction reference underline, and the changed and input line is displayed on the cloth.

When the transformation is completed in S117, the original mode is restored. Further, without ending the transformation, as described above, the lateral magnification 2a and the vertical magnification 2b in the figure-deformed state are appropriately applied [the lateral magnification 2a (L
2 / L1) ≠ (H2 / H1) vertical magnification 2b] is stored, and in S118, deformation data as a magnification is selected, and in S119, the deformation data is input. After this is finished, when the start key 34 is operated in S12, the embroidery frame E is driven from the display position to the initial setting position of the embroidery position corresponding to the needle, and if the start position is changed, Only the embroidery frame E is moved to the position without forming the stitch, and in S13, the changed embroidery stitch is formed according to the stitch data read from the start position in synchronization with the upper shaft phase detection sensor 7.

Further, when the new magnification is not changed, that is, the appropriate lateral magnification 2a and vertical magnification 2b which have already been registered.
When the case of the magnification is selected, the deformation data name is input and displayed in S120, the deformation data name is input in S121, and the stored deformation data of the magnification is read in S122. , S12, when the start key 34 is operated, in S13, an embroidery stitch is formed as described above.

Further, as shown in FIG. 4, in the case of changing the figure, instead of the figure deformation instructing means 15, in S130, an appropriate figure changing instructing means 38 is selected, and S13 is selected.
1 appropriate scaling (similar shape), S132 even allocation,
The horizontal enlargement / reduction in S133 and the vertical enlargement / reduction in S134 can be selected, and the deformation mode in S11 can be selected. Here, except for S11, the magnification value is 1
c is appropriately selected and displayed on the display device 2, and the enter key 3
4 is pressed to display the sewing direction reference underline, the start line, the end line, and the sewing direction reference upper line on the cloth, and the embroidery stitch is formed based on the registered graphic change data.

Next, as a second method, there is a method in which the stepping motor is not driven and the changed position is indicated only by the display. In this case, the setting can be performed quickly without any operation, but it is often necessary to make an adjustment at the time of shipment.

When a four-line square pattern is selected in S103, the light-transmissive display device 20 displays four lines of a predetermined size and displays them on the cloth. Further, since the input instruction display of the sewing direction reference underline is displayed on the display device 2 and the sewing direction reference underline on the cloth is displayed blinking so as to be movable, when changing the sewing direction reference underline, , Y direction manual operation key 18 is operated to output an operation signal.

In the graphic transformation mode, the function of the operation key is instructed by the light transmission type display device 20 without driving the stepping motor, and the display is moved in response to the signal to move the sewing direction reference underline. . When the sewing direction reference underline matches the desired position and the confirm key 34 is operated, it is determined that the instruction has been completed, and the movement signal from the initial setting position is calculated as the display data and the reference value of the sewing data as the deformation data. The display data storage means 25 and the arithmetic sewing data storage means 26 are stored, and the display of a predetermined reference shape is re-irradiated with the sewing direction reference underline set as a reference. If the sewing direction reference underline is not changed, the enter key 34 is operated.

Further, since the input instruction display of the start line is displayed on the display device 2 and the start line on the cloth blinks so as to be movable, when changing the start line, the X direction The manual operation key 17 is operated to output an operation signal. In the graphic transformation mode, the function of the operation key is instructed by the light transmissive display device 20 without driving the stepping motor to move the display in response to the signal and move the start line. When the start line coincides with the desired position and the confirm key 34 is operated, it is determined that the instruction has ended, and the movement signal from the initial setting position is displayed as the deformation data and the calculation display data as the reference value of the sewing data. The display is re-irradiated with the reference shape which is stored in the storage means 25 and the arithmetic sewing data storage means 26 and which has a predetermined reference shape based on the start line set for movement. Here, if the start line is not changed, the enter key 34 is operated.

Next, the input instruction display of the end line is displayed on the display device 2 as a message, and the end line on the cloth blinks so as to be movable. Therefore, when the end line is changed, the display is made. For X direction manual operation key 17
To output an operation signal. The sewing end line of the blinking display is moved with respect to the signal. When the confirmation key 34 is operated when the end line of the display coincides with the desired position, it is determined that the instruction is completed, and the movement amount from the reference value is used as the end line deformation data to display data and sewing data. The light transmission type display device 20 stores the deformation value in the calculation display data storage means 25 and the calculation sewing data storage means 26.
