ABSTRACT:
A driving device, includes a stepping motor having an exciting coil and a rotor; a driven member driven in accordance with a rotation of the rotor; a stopper mechanically stopping the driven member at a zero position; a controller controlling the state of excitation of the exciting coil; an induced voltage detector detecting an induced voltage generated by a change of magnetic flux according to the rotation of the rotor; and a zero position detector detecting a stoppage of the driven member at the zero position. The controller supplies an exciting pattern to the exciting coil at the time of processing of zero position detection. The exciting pattern includes a first exciting step for detecting the induced voltage and a second exciting step for rotation. Total periods of the first exciting step is greater than that of the second exciting step during an electrical angle 90° in the one cycle.
