Abstract

PURPOSE:To provide an electric-mechanical converter driving circuit for timepiece, in which pulse width of driving pulses for an electric-mechanical converter driven by two-phase driving pulses is controlled stepwise by the induced voltage of driving coil, whereby it is prevented that malfunctioning be caused when impact is applied to the timepiece.
