摘要:
An electronic timepiece has a wheel train mounted for undergoing rotation and a transmission wheel for undergoing rotation in accordance with rotation of the wheel train. A contact point spring is connected to the transmission wheel for rotation therewith. The contact point spring extends substantially linearly through a rotational center of the transmission wheel. First and second detection patterns contact the contact point spring during rotation of the transmission wheel to generate a rotational position detecting signal corresponding to a rotational position of the transmission wheel. The first and second detection patterns are disposed at an angle of substantially 180 degree relative to the rotational center of the transmission wheel.
