STEPPING MOTOR AND IMAGE PICKUP DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To provide a stepping motor that can reduce drive noise and vibration. SOLUTION: The stepping motor whose N pole and S pole are alternately magnetized in their circumferential directions, respectively, comprises: a magnet rotor 109 having a first phase magnetizing region 109A and a second phase magnetizing region 109B in the motor axial direction; and first phase and second phase stators 105A, 105B that are arranged in the motor axial direction at the external periphery of the magnet, and have coils 104A, 104B, respectively. A magnetizing angle in the first phase magnetizing region and a magnetizing angle in the second phase magnetizing region are different from each other. The stepping motor further comprises adjusting mechanisms 101, 102 and 107 in a position in the motor axial direction with respect to the stator of the magnet rotor. COPYRIGHT: (C)2007,JPO&INPIT
