..Pk is a defined point that defines the embroidery area.

The embroidery area starting end portion 30b is a contour line element at the starting end in the embroidery sewing direction among a plurality of contour line elements forming a contour line, and whether or not needle drop can be changed 2 One contour line element 41, 42 is included, and two embroidery line elements 43, 44 are similarly included in the embroidery area end end portion 30c that can change whether or not the needle is dropped. Therefore, by using the coordinate input device 13 and a predetermined function key on the keyboard 11, there is no needle drop for the outer shape line element 41, a needle drop for the outer shape line element 42, and a outer shape line element 43. No needle drop ・ Specify needle drop for each contour line element 44. As a result, first, the outer shape line elements 41 and 43 designated not to drop the needles are excluded, and the one line length L1 of the needle drop is the line segment PaPb length + the line segment PbP.
c length + line segment PcPd length + line segment PdPe length + line segment P
The other line segment length L2, which is obtained from the ePf length and is further dropped, is obtained from the line segment PgPh length + line segment PhPi length + line segment PiPj length + line segment PjPk length.

Next, the average line segment length Lx (mm) of these line segment lengths L1 and L2 is calculated, and based on this average line segment length Lx and thread density data d (number of stitches / mm). Then, the number H of stitches of the embroidery stitch to be applied to this embroidery area is calculated by the thread density data d × the average line segment length Lx, and the needle drop point divided by the number H of stitches for the line segment length L1 is obtained. Each line segment PaPb, Pb
Pc, PcPd, PdPe, and PePf are obtained respectively, and the needle drop points divided by the number H of stitches for the line segment length L2 are the line segments PgPh, PhPi, PiPj, Pj.
Each is required on Pk. Then, as shown in FIG. 26, with respect to the embroidery region start end portion 30b, the corrected stitches sequentially connecting the obtained needle drop points according to the condition that the needle drop does not occur with respect to the outer shape line element 41 are displayed. Displayed in. At the same time, these modified stitch data are replaced and stored in the working memory.

Also in this case, similarly to the above-described embodiment, the needle drop pattern of the embroidery stitch is changed by only designating the outline line element at the start end or the end end in the embroidery sewing direction and designating the presence or absence of the needle drop. And the needle drop pattern can be arbitrarily specified, and the stitch data of the embroidery area ends 30b and 30c are changed. Therefore, the stitch pattern at the embroidery start end and end end of the embroidery area having a complicated shape such as characters can be changed. It is possible to easily create stitch data that matches the entire embroidery area in good balance.
