At this time, the pattern editing means 12 in the embroidery sewing control means has, for example, the following character string selection setting function. First, the basic function of the pattern editing means 12 is as follows.
When a character pattern is selected by the sewing machine operator from various patterns read out from the sewing machine, an instruction of a sewing operation of the character pattern is given based on sewing data corresponding to the selected character pattern. However, when the selection is repeatedly performed for a plurality of character patterns, the sewing operation for the character string including the plurality of character patterns is executed.

On the other hand, when an instruction to change the arrangement state of the character string is input by the sewing machine operator at a stage before the sewing operation is started, the pattern editing means 12 matches the instruction. It has a function of appropriately rotating and moving the sewing data of the character string, and of appropriately driving and controlling the embroidery frame 7 based on the sewing data after the movement.

More specifically, an arrangement setting switch (see reference numeral 31 in FIG. 7 (a)) is provided on the touch panel section 5b as the input selection means for setting the arrangement of a plurality of selected patterns in a vertical or horizontal arrangement. ) And a typeface setting switch (see reference numeral 32 in FIG. 7 (b)) for setting the typefaces of a plurality of selected patterns to vertical writing or horizontal writing are displayed at a predetermined timing. The change of the direction of the vertical and horizontal writing (the typeface direction) and the direction of the vertical and horizontal positioning (array direction), which is the arrangement state of the columns, are appropriately changed and designated by the sewing machine operator. Then, the original sewing data is rotated and moved in position in accordance with each of the change directions specified, and the embroidery frame 7 is moved in a state after the movement.

The procedure for setting / changing a character string by the pattern editing means 12 in the embroidery sewing control means will be described below. First, as shown in FIG. 5, when the pattern selection menu starts and the character selection menu is displayed (step 1), a predetermined character pattern is selected by the sewing machine operator (step 2). The selected character pattern is added to a character string composed of the character pattern already selected (step 3).

At this time, if the character pattern once selected is to be deleted from the character string, the clear key is pressed (step 4), for example, the last character pattern of the character string is deleted (step 5).

At this stage, a typeface setting switch 31 for selecting vertical / horizontal writing as shown in FIG. 7A, and FIG. An array setting switch 32 for selecting between vertical and horizontal placement as shown in b) is displayed, and the following switching operation is performed by each pressing operation. First, the typeface setting switch 31
"Vertical writing" → "Horizontal writing" → "Vertical writing"
→ As in “horizontal writing”, the vertical writing mode and the horizontal writing mode are selected while being inverted (step 6 in FIG. 5).
One of the selected modes is set in the pattern editing means 12 (step 7 in FIG. 7). In addition, every time the array setting switch 32 is pressed, the portrait mode and the landscape mode are selected while being reversed, such as “vertical” → “horizontal” → “vertical” → “horizontal”. Then, the selected mode is set in the pattern editing unit 12 (step 9 in FIG. 6).

When such a procedure is completed, an end key of the character selection menu is displayed on the LCD display panel 5 of the touch panel display device (step 10 in FIG. 6), and the character can be selected without pressing the end key. If the menu is not to be ended, the process returns to step 2 described above. If the character selection menu is terminated by pressing the end key, a sewing screen for performing sewing is displayed on the LCD display panel 5 (step 11).

Therefore, in step 11, the arrangement state of the pattern according to the vertical writing / horizontal writing and the vertical / horizontal setting described above is changed to the vertical writing state (FIG. 6A) and the horizontal writing vertical state. One of the placement state (FIG. 6B), the horizontal placement state of vertical writing (FIG. 6C), and the horizontal placement state of horizontal writing (FIG. 6C) is displayed on the display screen of the LCD display panel 5. Is displayed.

Then, in the next step 12, the sewing data is changed in the pattern editing means 12 so as to be in one of the arrangement states displayed as described above, and the sewing operation start switch is pressed by the sewing machine operator. As a result, the character string sewing operation is executed.

As described above, according to the present embodiment, even if the character string is selected once, if it is desired to change the arrangement of the character string depending on the relationship with other patterns or the like, the character string may be placed before the sewing operation. For example, the sewing data of the character string is rotated and moved in accordance with an instruction from the input selection means, and the arrangement of the character string, that is, the vertical / horizontal writing and vertical / horizontal placement, can be easily and arbitrarily changed. .

Although the embodiments of the present invention made by the inventor have been specifically described above, the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the gist thereof. Needless to say.

The present invention is not limited to the arrangement of the character patterns as in the above-described embodiment, but can be similarly applied to various other patterns.
