Abstract

PURPOSE:To provide a watch converter, which has a low power and a high reliability, by providing a rotor magnet and a rotor pinion, which magnetically engages with the rotor magnet, so that the rotor pinion is turned unidirectionally in synchronism with the reciprocal movements, of the magnet. CONSTITUTION:When a current flows through a coil 1 so that a stator 2a is magnetized with an N pole whereas a stator 2b is magnetized with an S pole, a rotor magnet 3 and a rotor pinion 4 are turned a preset angle while keeping their magnetic engagement. Then, the tooth portion 4a of the rotor pinion 4 turns a gear 5 so that a ratchet wheel 6 is advanced one tooth or more. If, at this time, an input is turned off, the rotor magnet 3 is returned to the initial position by the static attracting torque. Since the pinion 4 cannot be turned in the opposite direction, the angle of rotation is increased for each rotation of the magnet 3 so that the train wheels subsequent to that 5 are converted into the one-directional rotational motions. Incidently, the power supply time to the coil is so short that the power consumption can be at a low level. Thus, it is possible to provide a converter which has a low power and a high reliability.
