するアナログ電子時計。 It has a step motor consisting of a rotor, a stator, and a coil, and a rotation detection means for detecting whether or not the rotor has rotated. In an analog electronic watch that immediately outputs a correction drive pulse in the opposite direction when it is determined to be rotating, the current induced in the coil in the opposite direction to the drive current by the vibration of the rotor is called a reverse current. , the period in which the rotation is detected is set to several milliseconds from when the first reverse current finishes flowing during repulsive rotation until the second reverse current flows and rotation can be detected. Analog electronic clock.
