BUTTON SEWING MACHINE AND BUTTON SEWING METHOD

PROBLEM TO BE SOLVED: To provide a button sewing machine capable of describing basic movement amount data on the basis of button sewing needle location point data, with hole-to-hole movement data showing buttonhole spacing, button hole inner needle location point data with a reference point in the button hole as the origin, and needle location order data. SOLUTION: The basic movement amount data shown in Fig.6 includes main movement amount data and correction movement amount data. In the Fig.6, data order shows the sequence of data, and movement content shows movement from the origin to a needle location point 1, and movement between needle location points from the needle location point 1 onward. The main movement amount data shows X-direction movement and Y-direction movement in a coordinate system. The correction movement amount data shows x-direction coordinate data and y-direction coordinate data with the reference point in the buttonhole as the origin. When the needle location point moves within the buttonhole, the main movement amount data is (0, 0). COPYRIGHT: (C)2010,JPO&INPIT
