Abstract
A stepping motor, a driver, a current detection circuit, a first driving circuit configured to output a first driving signal to the driver, a rotation detection circuit configured to detect rotation of the rotor, and a second driving circuit configured to output a second driving signal selected from plural kinds of the second driving signals with different supply times of the driving current supplied to the coil, and configured to output a correction driving pulse that is preset to the driver when, after outputting the second driving signal, the rotation detection circuit detects that the rotor is not rotating, are included, and a resistance value R[Ω] of the coil and the driving voltage V volts of the stepping motor satisfy 900×V[Ω]≤R[Ω]≤1100×V[Ω], and 1.8 volts≤V≤2.4 volts.
