Abstract
Abstract A data processing device for a sewing machine stores basic pattern data indicating the relative position between a needle and a material holding unit and including X and Y components of an X-Y coordinate. After setting a reference point on the X-Y coordinate plane and two angles ( alpha i, beta i) based on an X-axis and a Y-axis around the reference point, the data processing device rotates the X and Y components of the basic pattern data on the basis of the two angles ( alpha i, beta i) to form a transformed pattern, and stores the transformed pattern data. The processes such as rotation, inversion and inclination are executed by a single operation by designating the angles ( alpha i, beta i).
