Abstract
An oscillating stepping motor can reduce a required rotational angle of a rotor to drive a star wheel, reduce idle driving, cut the loss of energy required for the driving, reduce power consumption even in high-frequency driving, and stably operate. Two star wheels are located so that the tooth tips thereof are not engaged with each other. A rotor shaft includes a rotor pinion having two feed teeth at a certain aperture angle. One of the feed teeth feeds one of the driving wheels by oscillation of the rotor in one direction and the other of the feed teeth feeds the other of the driving wheels by the oscillation of the rotor in the other. The rotor then oscillates within a certain angle range, thereby sequentially rotating output gears in a certain direction by a certain angle.
