Abstract: A driving device includes a stepping motor having a rotor, a coil for rotating the rotor, and a processor that drives the stepping motor. The processor generates a driving pulse for rotating the rotor of the stepping motor to a prescribed position, and outputs the driving pulse to the coil; and generates a rotation assistance pulse for rotating the rotor of the stepping motor at a prescribed speed, and outputs the rotation assistance pulse to the coil, after outputting the driving pulse but before EMF is produced by the rotation of the rotor of the stepping motor caused by the driving pulse.

Abstract: Disclosed is a stepping motor including a rotor, a stator which includes a rotor accommodating hole, a pair of outer notches to determine positions of saturated magnetic fluxes and inner notches disposed on an inner periphery of the stator around the rotor accommodating hole, the inner notches determining stably stationary positions of the rotor, and a coil block configured by a coil wound around a coil core which is magnetically coupled to the stator, and the outer notches are disposed on an outer periphery of the stator on opposite sides of the rotor accommodating hole. And a line that connects narrowest portions between the outer notches and the rotor accommodating hole and extends through a center of the rotor accommodating hole shifts by a predetermined angle from a line that extends through the center of the rotor accommodating hole and is orthogonal to an extending direction of the stator.

Abstract: A high-speed rotating wheel rotates at high speed by a third stepper motor which meshes with a portion of teeth of a ratchet wheel. A transmission projection of the ratchet wheel moves within an elongated hole of a transmission wheel which rotates with the movement of the hour hand. The ratchet wheel rotates at high speed, and a display wheel rotates at high speed by the high speed rotation of the ratchet wheel via a feed wheel. When normally moving the hour hand, the ratchet wheel rotates with the transmitting wheel and the portion of teeth of the ratchet wheel is made to approach the high-speed rotating wheel. When the display of the display wheel changes, the high-speed rotating wheel meshes with the portion of teeth of the ratchet wheel and rotates the ratchet wheel at high-speed. Accordingly, the date display of the display wheel can be quickly changed.
