Abstract
A hand driving device includes first to third stepping motors, a driving circuit, a magnetic sensor, and at least one processor. The first to third stepping motors move hands. The driving circuit drives the first to third stepping motors. The processor controls a magnetic sensor, based on movement of the first to third stepping motors, determines whether or not the driving circuit has rotated the stepping motors while the magnetic sensor does not perform measurement, and, when determining that the motors have not rotated, makes the magnetic sensor start measurement.
