PROBLEM TO BE SOLVED: To provide an electronic equipment for stably performing fast forward of a stepping motor at a high speed. SOLUTION: A coil 71 for detection which is wound coaxially with a coil 11 for drive is provided, the inverse induced voltage of the coil 71 for detection is detected by a detection circuit 75, and a detection timing, where a first peak for indicating that a rotor 13 has rotated appears is captured. Then, a next drive pulse is supplied after the detection timing, so that the drive pulse can be supplied at high speed, while the rotation of the rotor 13 is being confirmed, thus enabling stable performance of fast forward. |
