摘要：
A pulse motor driving device having a rotation detecting unit adapted to detect whether or not a pulse motor rotates. In this device, a control unit performs an operation of increasing the effective value of the driving power of the pulse motor and performs an operation of lowering the effective value of the driving power thereof when it is detected by the rotation detecting unit that the pulse motor does not rotate. Further, the control unit interrupts the operation of lowering the effective value of the driving power of the pulse motor when a magnetic field is detected by a magnetic detecting unit.
