Abstract
By a program executed by a CPU, a determination is made as to whether a direction in which a next stitch is to be formed belongs to a predetermined area corresponding to a hitch stitch, and upon determination that the direction in which the next stitch is to be formed belongs to the predetermined area, detour control is performed which includes moving a holding member, holding a sewing workpiece, so as to detour an upper thread, extending downward from a sewing needle, in a direction corresponding to a perfect stitch and then further moving the holding member to a target position corresponding to the next stitch. Various conditions for the detour control are variably set via an operation panel and a program executed by the CPU. Such variable setting can be done by user's operations via the operation panel, by setting detour-controlling data, and/or the like.
