Abstract
PURPOSE:To perform the control of the watch circuit for the analog-type electronic watch by securing the photoelectric detection for the position of the time display unit and then using the detected signals. CONSTITUTION:Gears 31-35 are turned by rotor 2a of the step motor, and thus the watch hands are driven. In this case, optical path modulation component 20A (code plate) is turned in synchronization with gear 32 attached with the second hand.And the position of component 20A is detected by photo diode 6a which receives the light of light emitting diode 6c. With this detected signals, the control is given to the gain and loss of the time display unit, the alarm ringing and others.
