ABSTRACT:
An inner rotor type scanner motor rotating a rotary polygon mirror for deflection scanning is composed of two units, a rotary unit and a stationary unit. Then balancing can readily be achieved on two planes of the rotary polygon mirror and a drive magnet of the motor. The rotary unit is arranged in such a manner that a motor housing holds a bearing of a rotary member to which the rotary polygon mirror and drive magnet are fixed, and the stationary unit is arranged in such a manner that a stator coil and a magnetic member are mounted on a base.
