Abstract
A stepping motor control device includes a driving unit that drives a stepping motor including a rotor that rotates a hand and a coil that generates a magnetic flux for rotating the rotor, a control unit that outputs, to the driving unit, a driving pulse for rotating the rotor and a swinging pulse for swinging the rotor, a voltage detecting unit that detects an induced voltage generated in the coil when the rotor vibrates, and a determining unit that determines, based on a result of the detection of the voltage detecting unit, a mechanical load received by the rotor.
