PROBLEM TO BE SOLVED: To provide a sewing frame driving apparatus of a sewing machine, with which sewing frame drive is made precisely to form high-precision seaming and speed up to improve productivity and which has a simple structure and is readily assembled. SOLUTION: A sewing frame 9 for stretching a finished fabric is arranged right above a table 4, a plane stator 10 having an XY dimensions corresponding to both driving ranges in the X direction and the Y direction of the sewing frame 9 is installed at the table 4 side, a mover 11 for producing both driving forces in the X direction and the Y direction by interaction with the plane stator 10 is installed at the sewing frame 9 side. The sewing frame 9 is driven in the X direction and the Y direction by a linear biaxial motor 8 including the plane stator 10 and the mover 11 and its controller. COPYRIGHT: (C)2003,JPO
