摘要： In a needle plate, a needle plate hole is configured to include a hole-side cutting side that cuts a cutting target object together with a blade portion, and a relief side that allows a cut portion of the cutting target object to escape. Specifically, the needle plate hole has the hole-side cutting side that shears the cutting target object together with a blade-side cutting side of the blade portion, and the relief side that forms a gap between the blade portion to be inserted and the relief side. In this manner, in the former stage of cutting processing, the cutting target object can be cut by the hole-side cutting side and the blade-side cutting side.

摘要： In a sewing machine, a plurality of needle plate holes are formed in a needle plate. The needle plate holes are arranged at positions respectively corresponding to a plurality of blade-side rotation positions of a cutwork blade. In this manner, the needle plate hole is formed in a shape corresponding to a shape of a blade portion, and a direction of the needle plate hole can match a direction of the blade portion that is arranged above to face the needle plate hole. Specifically, a linear hole-side cutting surface corresponding to a blade-side cutting surface of the blade portion is formed in the needle plate hole, and the blade-side cutting surface and the hole-side cutting surface can be arranged to face each other in a direction orthogonal to both the surfaces in a plan view.

摘要： A thread color comparison unit compares and judges whether or not a comparison target is the same as a comparison reference with a given thread color of a given design stored in a thread color storage unit as the comparison target and with a given thread color of another given design that differs from the given design as the comparison reference. A thread color grouping unit performs grouping for the comparison target and the comparison reference included in different designs when the comparison target and the comparison reference are the same color. When the thread color comparison unit has judged that the comparison target is the same as the comparison reference, the thread color storage unit stores information such that the comparison target is to be sewn together with the comparison reference that has been judged to be the same, and the sewing data for the comparison target is removed.
