[Overall Flow of Pattern Editing] Next, the overall flow of pattern editing in the embroidery mode in the sewing machine configured as described above will be described with reference to FIG.

When the power is turned on (step S1) and the sewing machine is in the embroidery mode, the screen shown in FIG. 5 appears on the display substrate 60 (step S2). The operator operates the mark key 72
Then, by selecting various patterns appearing when the mark key is pressed, an embroidery pattern to be sewn can be selected (step S3). For example, in FIG. 5, the “mark 1” key is operated, and 12 types of patterns related to this mark key appear, and another “mark n (n =
Similarly, when a key "2, 3, 4, 5)" is selected, a pattern related to the key appears, and the operator selects a desired pattern.

Here, when the operator selects the pattern 73 in FIG. 5, the selected pattern 74 is displayed at the top of the screen (step S4). When the layout of the pattern is edited, when the "layout screen" key 75 is pressed, the screen shifts to a layout screen in which various keys 80 are arranged as shown in FIG. 6A (step S5). , S
6).

The "sewing" key 80a displayed on the layout screen is used to confirm in which area on the sewing the selected pattern is actually sewn. S7) A sewing range confirmation process is performed as described later (step S30). The "combination" key 80b is used to select a plurality of patterns. When this key is pressed (step S8), the screen returns to the pattern selection screen in step S2, and the initially selected one or a plurality of patterns is changed to one pattern. A plurality of patterns can be created as a set, and another one or a plurality of patterns are used as another set. The plurality of sets of patterns are simultaneously displayed on the layout screen, and the editing operation switches displayed on the layout screen independently of any of the patterns specified by the confirmation keys 80j and 80i described later. Editing operation becomes possible.

The "embroidery frame" key 80c displays a sewing area for the selected embroidery frame on the screen. When this key is pressed (step S9), an embroidery frame setting process described later is performed (step S40). . The "position / rotation" key 80d is used to adjust or rotate the position of the selected pattern. When this key is pressed (step S10), a position / rotation movement process described later is performed (step S50). . In addition, the “moyo size” key 80
"e" is for changing the size of the pattern. When this key is pressed (step S11), a pattern size changing process described later is performed (step S80).

The "reverse" key 80g is a key for reversing the pattern symmetrically with respect to the reference line. When this key is pressed (step S12), a pattern reversal process is performed (step S12).
90). The "character size / character spacing" key 80f is a key for adjusting the character size and character spacing of the character string composed of the selected character. When this key is pressed (step S1)
3) A character size / interval change process described later is performed (step S100).

After the editing of the pattern is completed, "editing end"
When the key 80h is pressed (step S14), the size of the embroidery frame set on the sewing machine is detected, the display of the position of the pattern in the embroidery frame is performed according to the size of the embroidery frame, and the display of the parts of the pattern. An edit confirmation screen as shown in FIG. 6 (B) appears, in which a stitch time display, a vertical display and the like are displayed (step S15). Here, when the "Nuihani" key 80a is pressed (step S1).
6) A sewing range confirmation process is performed (step S3).
0), when the "combination" key 80b is pressed (step S1).
7) Returning to the pattern selection screen in step S2, another pattern can be selected and combined, and the "edit" key 80m
Pressing (Step S18) returns to the layout screen of Step S6.

As described above, by editing (changing) the selected pattern or its data, when the editing is completed, the data of the selected pattern is updated to the edited pattern, and the sewing data corresponding to the edited pattern is updated. Is created. Therefore, if the start switch is turned on during the process surrounded by the dotted line while the edit confirmation screen is displayed, the process proceeds to step S
The sewing execution interruption process indicated by reference numeral 20 is performed, and if there is no error (step S21), the sewing is executed according to the sewing data corresponding to the selected and edited pattern (step S23). Processing is performed (step S22).

In FIGS. 6A and 6B, "confirm" keys 80j and 80i are keys for displaying the previous or subsequent selection display information in the buffer.
The “delete” key 80k is a key for deleting the selected pattern.

[Sewing range confirmation processing] Next, step S3
The sewing range confirmation process performed at 0 will be described with reference to the flowchart of FIG. This is for visually checking and confirming where the pattern on the display screen that has been selected and edited is on the actual sewing product.

When a pattern to be embroidered is selected and edited, a screen shown in FIG. 6A appears. At this time, a sewing area 81 corresponding to the embroidery frame is displayed on the display substrate 60 in a pseudo manner. The done pattern 74 is edited in this area 81. As shown in FIG. 8A, the control unit 11 forms a polygon (square) circumscribing the pattern 74 from the image data of the selected or edited pattern 74, and The coordinate positions (Xn, Yn) (n = 0 to 4) of a plurality of predetermined points defining the outline shape, that is, four vertices A, B, C, and D, and the center O of the polygon are calculated.

During or after editing the pattern, when the "Nuihan" key 80a is pressed, a sewing range confirmation screen 82 as shown in FIG. 8B appears (step S31), and the vertices A to D are displayed. In addition, keys 82a to 82e as setting means corresponding to a predetermined point of the center O are displayed and set. Each of these keys may be directly set at a vertex of the pattern in the area 81, but in the case of a small pattern, it is difficult to determine the key. Therefore, as shown in FIG. Is displayed on the same position in a fixed form regardless of the size of the pattern.

Here, when the keys 82a to 82e are operated through the touch panel, the control section 11 as the signal output means and the control means determines which key is pressed, and determines a predetermined point corresponding to each key. Is read (step S32), and a position signal corresponding to the coordinate position is output. According to the position signal, the position in the embroidery frame corresponding to the predetermined point is set to a predetermined position with respect to the sewing needle, for example, a needle drop point. Then, the embroidery frame is moved so as to move (step S33). At this time, the needle can be actually lowered.

For example, when the key 82a is operated, the coordinate position A (X1, Y1) is identified, and the movement amount of the embroidery frame is calculated from the coordinate value of this position and the coordinate value of the needle drop point.
The direction motors 54 and 55 are driven, and the embroidery frame is moved such that the position in the embroidery frame corresponding to A coincides with the needle drop point. This is because when the other keys 82b to 82e are pressed,
Similarly, the embroidery frames are moved so that the positions in the embroidery frames corresponding to B, C, D, and E coincide with the needle drop points.

As described above, the operator can operate the keys 82a-82
By operating e, it is possible to know where the edited pattern is located on the actual sewn product. In particular, the pattern already exists on the sewn product, and how the currently edited pattern is It is possible to roughly know at what position the sewing is performed or how much margin the actual pattern is sewn with respect to the end of the embroidery frame. This makes it possible to confirm whether or not the pattern should be re-edited before sewing, thereby providing a useful means.

The return key 80n in FIG.
Is pressed (step S34), the embroidery frame can be returned to the original position (step S35). When the pattern needs to be re-edited for further fine adjustment, the key 80p is pressed to re-edit the pattern as shown in FIG. You can return to the layout screen.

[Embroidery frame setting process] Next, step S40
The setting process of the embroidery frame performed in the step will be described with reference to the flow shown in FIG.

When the "embroidery frame" key 80c is operated on the layout screen shown in FIG. 6A, an embroidery frame selection screen 83 as shown in FIG. 10 is displayed (step S4).
1) A "large frame" key 83 as embroidery frame selection means for setting or selecting embroidery frames of three sizes, large, medium and small.
a, a "medium frame" key 83b, a "small frame" key 83c, and a "joint embroidery" key 83d for sewing a large pattern that cannot fit in the largest embroidery frame are displayed.

The sewing area 81 in which the initially selected pattern 74 is displayed has a size corresponding to a large embroidery frame, is displayed in a reduced scale at a predetermined ratio, and the selected pattern 74 is actually displayed. The size is reduced and displayed at the same ratio as the size of the cloth when sewing on the cloth.

Here, for example, a "medium frame" key 83b,
Alternatively, when the "small frame" key 83c is operated (step S42), the control unit (display control means) 11 controls the large embroidery of the selected embroidery frame regardless of the size of the embroidery frame actually mounted on the sewing machine. The ratio to the frame is calculated (step S43), and sewing areas 81 'and 81 "corresponding to the medium-sized embroidery frame and the small-sized embroidery frame are created, and the sewing area 8 is formed.
1 to display the sewing area 81 'or 81 "(step S44). Since the size of the pattern 74 is not related to the switching of the sewing area, the operator checks the embroidery frame most suitable for the sewing pattern on the screen. Therefore, when the optimum embroidery frame is confirmed, the actual embroidery frame can be replaced with the actual embroidery frame, and the sewing area corresponding to the embroidery frame can be changed according to the selected embroidery frame. Since the changed or displayed pattern is displayed, an optimum embroidery frame for sewing the selected or edited pattern can be selected before the start of sewing and can be mounted on the sewing machine, and an optimum stitch can be formed.

Depending on the selected embroidery frame, the pattern may run out of the sewing area on the screen.
At that time, a warning message such as "There is a pattern that goes out of the frame due to the change of the frame. Do you want to continue changing the frame?" Then, when continuing (step S45), the process returns to step S42 to select an embroidery frame.

By pressing the "sew-on" key 80a, the above-described sewing range confirmation processing (step S3)
0) can be performed (step S46), and when the "positioning line" key 80q is pressed (step S47), a grid line 81c can be displayed on the screen (step S48). Therefore, the operator can more accurately grasp the position of the pattern with respect to the selected embroidery frame.

Here, by pressing the "return" key 80p, it is possible to return to the layout screen of FIG. 6A (step S49).

The type of embroidery frame mounted on the sewing machine is detected by an embroidery frame sensor realized by the frame switches 52 and 53, and keys 83a, 83b and 83c are controlled by a control unit (discriminating means, control means) 11. The embroidery frame selected by the embroidery frame and the embroidery frame detected by the embroidery frame sensor are determined to match or mismatch, and when a sewing machine start command is output, when the determination means determines that the embroidery frame does not match, the sewing machine is started. It can be prohibited. As a result, the mismatch between the selected embroidery frame and the actually mounted embroidery frame can be prevented, so that sewing errors can be reduced.

[Position / Rotation Movement Processing] Next, step S
The position / rotational movement process performed at 50 will be described with reference to the flowchart of FIG.

(Rotation of Pattern) When it is desired to rotate and edit the selected pattern or character, the "position / rotation" key 80d is pressed on the layout screen shown in FIG. By this operation, the screen becomes the edit screen shown in FIG.
When the "rotation" key 86 is pressed (step S51), a pattern rotation screen 85 appears (step S52).

On this screen, a first key 85a as a rotation angle setting means capable of adding and setting a rotation angle of 5 degrees or less including one degree (1 degree in the illustrated example) for each operation, and rotation of the key 85a A rotation angle different from the digit of the angle (1 in the illustrated example)
0 degrees) for each operation, a second key 85b as a rotation angle setting means, and keys 85a and 85
A third key 85c as a rotation angle setting means that can add and set a rotation angle (100 degrees in the illustrated example) different from the digit of the rotation angle b in each operation, and a setting key to set the rotation angle to 0 degrees 85d appears. in this way,
The rotation angle setting means includes first, second, and third keys 85a, 85a.
5b and 85c.

Then, the operator operates the keys 85a, 85b, 85c selectively according to the angle at which the pattern is to be rotated. For example, to rotate the key by 12 degrees, the key 85b is pressed once and the key 85a is pressed twice. To rotate the key by 125 degrees, the key 85c is pressed once and the key 85b is pressed twice.
Key 85a five times (step S53).

Since the angles set for each key operation are added and accumulated (step S54), the added accumulated value is sequentially displayed as a numerical value in the area 85f for each key operation.
Also, a graphic is displayed in the area 85g. In the illustrated example, it is shown that an angle of 90 degrees is set.

If it is desired to reset this angle, the pattern can be returned to the original state (step S56) by pressing the key 85d for setting 0 degrees (step S55). When the "change" key 85e is pressed (step S57), the pattern 74 can be rotated by the set angle and displayed (step S58). When the "return" key 80p is pressed (step S59), the screen can return to the layout screen (step S6).

When the editing is completed, the control unit (arithmetic means) 1
1 calculates the sewing data of the pattern which rotates by the set angle from the sewing data of the selected pattern, thereby forming the seam of the rotated pattern on the cloth by the calculated sewing data of the pattern.

In such a configuration, at least three types of angles with different digits can be set, so that an arbitrary angle can be set with a small number of key operations. In this case, if a key capable of setting an angle of a different unit is provided within a range allowed by the space of the screen, the pattern can be rotated at a desired angle with a smaller number of key operations.

By setting the rotation angle of the smallest digit to a small angle, the pattern can be rotated by a small angle.
It becomes possible to express a subtle rotating pattern and sew.
Therefore, the smaller the angle that can be set with the key 85a, the finer the pattern can be rotated. However, the number of key operations increases depending on the set angle (for example, to set 5 degrees, it is necessary to press the key 85a five times). ) In a sewing machine in which the minute rotation is not set so much, this can be set to an angle value larger than 1 degree.

The pattern 74 may be rotated every time each key is operated without waiting for the operation of the "change" key 85e.

(Movement of Display Position of Pattern) On the other hand, if the user wants to edit the display position of the selected pattern or character, he presses the "position" key 87 on the edit screen shown in FIG. 12 (step S60). As shown in FIG. 13, a display position movement screen 90 appears (step S61), and the screen includes eight direction instruction keys 90a and frame edge keys 9 respectively.
0b and the center key 90c are displayed.

Since the pattern 74 to be sewn on the cloth set in the embroidery frame is displayed in the sewing area 81 corresponding to the embroidery frame, the display position of the pattern 74 in the sewing area 81 is moved and edited. The actual sewing position of the pattern in the embroidery frame can be set by this editing.

The display position of the pattern immediately after the selection of the pattern is located at the center of the embroidery frame display. The needle is also located at the center of the embroidery frame. The movement of the display position of the pattern is performed by eight direction instruction keys 9 as moving means (first and second moving means).
0a, the center key 90c, and the frame end key 90b as movement control means. To move the pattern 74 slightly by a predetermined amount in a predetermined direction, the frame end key 90b
Is not operated (No at Step S62), the direction key 90a and the center key 90c are operated (Step S6).
3). With this, the display position of the pattern moves by a predetermined minute distance for each key operation in the designated direction,
The embroidery frame is also moved to a position corresponding to the display position by driving the XY motor (step S64). For example, when the direction indicating key 90a indicating the upper right direction is operated, the display position of the pattern moves a small distance in each direction of the operation of the key and moves to the center of the sewing area 81. When the center key 90c is pressed, it moves a predetermined minute distance toward the center.

On the other hand, when the frame end key 90b is operated (Yes at step S62), the fine movement of the sewing pattern is switched to the one-step movement to the end of the sewing area. For example, when the direction instruction key 90a indicating the upper right direction is operated (step S65), the pattern 74 moves at a high speed to the end (frame end) 81a of the sewing area located in that direction in one step (step S65). S66). Here, when the "return" key 80p is pressed (step S67), it is possible to return to the layout screen (step S6).

As described above, the sewing pattern can be minutely moved in the predetermined direction on the editing screen by a predetermined amount, and can be moved to the end of the sewing area in one step at a high speed over a long distance. It is possible to reduce the number of operations for moving the pattern, reduce the time required to move the display position of the pattern, and improve the efficiency of pattern editing.

In the above embodiment, the first moving means for slightly moving the sewing pattern in the sewing area in at least one predetermined direction by a predetermined amount every time the operation is performed, and moving the sewing pattern to the predetermined position in the predetermined one direction in one step. The second moving means can also be used as the direction instruction key 90a, and its application (function) can be changed by operating the frame end key 90b.

Although the display position of the pattern is switched from the minute movement to the one-step high-speed movement by using the frame end key 90b, the direction indication is performed by using the timer (measurement means) provided in the control unit 11. A key operation (pressing) time may be measured, and when the operation time has elapsed for a predetermined time, a long distance may be moved at a high speed in one step. Therefore, in this case, if the direction instruction key is operated, the operation moves a minute distance, and if the operation key is continuously operated, after a predetermined time elapses, the operation moves a long distance to the end at once in a short time. .

In addition to the high-speed movement to the end of the sewing area in one step, the high-speed movement to the center of the sewing area may be performed.

(Pattern Enlarging Process) If the user wants to enlarge and display the selected pattern, he or she presses the "zoom" key 88 on the editing screen shown in FIG. 12 or FIG. 13 (step S70). As shown in (A), a zoom screen 91 appears (step S71). On this screen, eight direction instruction keys 90a as shown in FIG.
In addition to the above, “double” keys 91a and “4” as magnification setting means for enlarging and displaying a display pattern twice or four times, respectively.
"Double" key 91b and "standard" key 91 for returning to the original magnification
c is displayed.

Here, the area 81b of the pattern to be enlarged and displayed
Is designated with a finger or a touch pen or the like and, for example, the "double" key 91a is pressed (step S72), as shown in FIG. 14B, under the control of the control unit 11 as a pattern editing unit, The pattern of the designated area 81b is displayed in an enlarged size of 2 (step S73). In addition, the enlarged pattern can be re-enlarged by specifying an area again. By operating the direction instruction key 90a here (step S74), the enlarged pattern can be moved one step at a time in the indicated direction and displayed (step S75).

In the case of moving the pattern using the direction instruction key in FIG. 13, the embroidery frame moves from the reference position in accordance with the movement of the pattern. Therefore, even if the enlarged pattern is moved, the embroidery frame does not move. Similarly, since the sewing data of the pattern is not related to the enlargement of the pattern, the actual sewing is performed by a sewing machine (sewing means) according to the sewing data of the edited pattern before the enlargement.

Although the magnification of the enlarged pattern is displayed on the key itself, it may be displayed on the screen area.

Further, by pressing a "positioning line" key 80q on the zoom screen, a grid line 81 is added to the sewing area 81.
c can be subtracted, a part of which can be seen in FIG. 14 (B).

The enlargement magnification is also effective on a pattern size change screen shown in FIG. 16 described later and a character size adjustment screen shown in FIG. 22 (A), and is an effective means for pattern or character editing.

When the user wants to return the magnification to the original value, the user can press the "standard" key 91c to return to the default value. In step S76, the "return" key 80p
Pressing returns to the layout screen (step S6).

As described above, the pattern can be enlarged and displayed to a desired size with a few key operations, so that it is not necessary to repeat the enlargement process many times, and the editing efficiency can be improved.

[Pattern Size Change Processing] The pattern size change processing (step S80) is for enlarging or reducing the pattern size, and is performed according to the flow shown in FIG. When the “moyo size” key 80e is operated on the layout screen of FIG. 6A, a pattern size change screen 92 shown in FIG. 16 is displayed (step S81), and the pattern is changed to 90.
Four magnification keys 92a to 92d for setting reduction or enlargement at magnifications of%, 100%, 110%, and 120%, and "+" key 92e and "-" key 92f for manually increasing / decreasing magnification.
Is displayed. This magnification is set within a range where the sewing pitch is not extremely narrowed or roughened in order to directly enlarge or reduce the original sewing data.

When any one of the change keys 92a to 92d is pressed (step S82), the magnification is set manually by the "+" key 92e and the "-" key 92f (step S83). The size of the pattern 74 is calculated at the magnification displayed on the 92g (step S84).
In the case of the magnification keys 92a to 92d, the color of the operated key changes, and the "+" key 92e,
In the case of the "-" key 92f, the set magnification% is displayed in the area 92g (step S85), and the pattern is enlarged or reduced at that magnification (step S86).
A scaling operation of the sewing data of the selected pattern is performed, and when the sewing is performed in step S20, the pattern is formed on the cloth at the set magnification. When the “return” key 80p is pressed (step S87), the layout screen (step S6)
You can go back to

The character size is changed in the "character size / interval change processing" described later. The size of the pattern and the size of the character may be changed using the same key.
In this case, the range of the enlargement / reduction ratio of the pattern and the character may be stored independently, and the setting range of the enlargement / reduction may be automatically selected by determining whether the pattern or the character.

[Pattern Reversal Processing] The pattern reversal processing (step S90) shown in FIG. 17 is for reversing a pattern or a character symmetrically with respect to a predetermined axis, and is performed on the layout screen shown in FIG. When the "Reverse" key 80g is operated,
As shown in FIG. 18, an inversion processing screen 93 appears, and axis keys 93a and 93b are displayed (step S9).
1). For example, when it is desired to invert the pattern symmetrically with respect to a predetermined axis (horizontal axis), by pressing the key 93a (step S92), the pattern 74 is displayed symmetrically inverted with respect to the horizontal axis (step S93). ), The inversion of the sewing data of the selected pattern is performed, and when the sewing is executed in step S20, the inverted pattern is formed on the cloth. Here, similarly, when the "return" key 80p is pressed (step S94), it is possible to return to the layout screen (step S6).

[Character Size / Spacing Change Processing] FIG. 19 shows the flow of the character size / spacing change processing (step S100). When a character as a pattern is selected, the screen shifts to a screen as shown in FIG. 20A in which a character as a pattern can be selected by operating the mark key 72 from the screen shown in FIG.

First, a plurality of desired character keys are selected on the character selection screen as shown in FIG.
To make the character spacing of “B” and “C” smaller than the spacing of “A” and “B” for the character string of “BC”, select the character key of “B” and then press When the character key "C" is selected after operating the key 80s, the upper part of the screen 6 is controlled under the control of the control unit 11 functioning as a character string creating means.
“AB ← C” is displayed at 0 ′, and it is displayed that the character string “ABC” with the character spacing of “B” and “C” reduced is selected. “←” input between “B” and “C” by the operation of the “character-to-character pawl” key 80 s is a character spacing adjustment code having a function to adjust (close) the character spacing before and after the character. When the "layout screen" key 75 of the character selection screen is operated at this time, the screen is switched to the layout screen of FIG. 95 can be confirmed by being displayed in the sewing area 81. Further, when the sewing is performed in step S20, the embroidery sewing is performed by the character string arrangement in which the space between characters is smaller between BC and AB than between AB.

Further, as shown in FIG. 20A, for example, when a character string of “AB ← C” is selected and then a character string of “DEF” is selected as another set, “AB ← C” is selected. After selecting the character string "", the "character delimiter" key 80u is operated, and then the character string "DEF" is selected. Then,
“AB ← C” DEF is displayed on the upper portion 60 ′ of the selection screen, and a parenthesis mark is displayed between “AB ← C” and “DEF” as a character delimiter. At this time, when the “layout screen” key 75 of the character selection screen is operated, the screen is switched to the layout screen, and the ABC character string and the D
The EF character string is displayed. Here, “AB ← C” and “D
Confirm one of the pairs you want to edit among the pairs of "EF"
0i, 80j, and editing operations such as layout movement, rotation, and inversion can be individually performed on the selected set of patterns. For example, as shown in FIG. DEF ”can be moved and arranged below“ AB ← C ”, and a character string 95 corresponding to the operation is displayed in the sewing area 81. When the sewing is executed in step S20, the embroidery sewing corresponding to the editing operation is performed.

In the above-described embodiment, the character spacing is narrowed by the character spacing adjustment code. However, for example, a "character space widening" key is provided, and a "→" code is included between predetermined characters by this key. By doing so, the character spacing can be adjusted to be wider than the other character spacings.

To switch between horizontal writing and vertical writing of the selected character, a plurality of desired character keys are selected on the character selection screen, and a character string such as "Ai" is displayed at the top of the screen, and All that is required is to operate the “/ width” key 80r. In order to confirm that the arrangement of the character strings is actually vertically written, the user can operate the “layout screen” key 75 of the character selection screen to switch to the layout screen.
The vertical writing display on the embroidery frame can be confirmed.

If the "character size" key 80t is operated before the character string is selected, the screen shown in FIG. 20B is displayed, and the character size can be set using the key 94. The character size of the character string to be selected can be set.

Further, if the "character size" or the "character spacing" is to be changed collectively after the character string "ABC" is selected first, the "character size / character spacing" key 80f is displayed on this layout screen. Operate. This allows
A character size and character space change screen 96 as shown in FIG. 22 (A) appears (step S101), and an "open" key 96a, a "seed" key 96b for adjusting the character space, and a character A "+" key 96c and a "-" key 96d for adjusting the size are displayed.

If the character size is to be changed (Yes at step S102), the "+" key 96c is pressed.
Using the "-" key 96d, 7 mm to 60 in 1 mm units
The character size is increased or decreased until the desired character size appears in the area 96e within the range of mm. This set value is read (step S103), the character string display data is calculated accordingly (step S104), and displayed in the sewing area 81 (step S105), and the sewing data is changed with the changed character size. Then, new sewing data is created (step S106). In this case, the enlarged and reduced sewing data may be stored in advance and selected.

On the other hand, when the character spacing is to be adjusted (Yes at step S110), the "Hiroku" key 96a and the "Sekuma"
One of the keys 96b is operated to read it (step S111), calculate character string display data at the read character interval (step S112), and store it in the sewing area 8
1 (step S113), and creates sewing data at the changed character spacing (step S11).
4). Thereafter, when the "return" key 80p is pressed (step S115), the screen can return to the layout screen.

In this manner, the character size and / or the character spacing of the character string composed of the selected character can be adjusted (changed). For example, the character spacing of the character string 95 is reduced while the character size is kept unchanged. However, in FIG.
FIG. 22C shows an example in which the character size is increased and the character interval is increased.

It is determined whether the character size and the character interval are within the frame size within the range of the embroidery frame. If the size is longer than the frame size, the changeable range is limited. In this case, the characters are moved to 9 by rotating the pattern.
By rotating the embroidery frame by 0 ° and performing a change operation on a long portion of the embroidery frame, the size and interval can be changed more greatly.

Note that the character spacing may be provided with a key capable of setting not only two kinds of wide or narrow, but also more kinds. Further, similarly to the adjustment of the character size, a default value is set using the ± key. It may be set to increase or decrease.

As described above, since the spacing and / or character size of the characters constituting the selected character string can be adjusted, the pattern composed of the character strings can be edited even after the character is selected.
The editing efficiency of the character string pattern can be improved.

[0103]

As described above, according to the present invention, the sewing pattern can be slightly moved in the editing screen by a predetermined amount in a predetermined direction, and at a predetermined position in one step, for example, the end of the sewing area corresponding to the embroidery frame. Can be moved at high speed, the number of operations when moving the selected pattern in the sewing area (frame) can be reduced, and the time required to move the display position of the pattern can be shortened. Efficiency can be improved.
