While reading and analyzing embroidery data for sewing, when an X-direction moving amount and a Y-direction moving amount are at most predetermined small amounts and seam stop data indicating a finish stitch-concentrated portion where embroidery operation is repeated over three stitches for a seam stop, is detected, an X-direction moving amount of a second one of finish stitch data is changed, the X-direction moving amount of a third one of the finish stitch data is changed, and finish stitch concentration of the seam stop is resolved by dispersing finish stitch positions. As a result, not only cutting of thread and swelling of a seam can be prevented but also a thread tightening operation can sufficiently be carried out by reducing moving distance of embroidery thread during thread tightening.
