摘要： With a stepping motor driving device, a driving signal generating unit generates a first driving signal and a second driving signal which are to be supplied to an A-phase coil and a B-phase coil of a stepping motor, respectively. A first switching circuit includes multiple switches connected to the A-phase coil of the stepping motor, and controls the current that flows through the A-phase coil according to a first driving signal generated by the driving signal generating unit. A second switching circuit includes multiple switches connected to the B-phase coil of the stepping motor, and controls the current that flows through the B-phase coil according to a second driving signal generated by the driving signal generating unit. The driving signal generating unit has a configuration which provides a function of adjusting the phase difference between the first driving signal and the second driving signal.
