ABSTRACT:
The detection of a pulse signal in an initialization pattern is ensured regardless of the position where a DC motor is stopped. A CPU detects the pulse signal generated by the pulse generator and an angle of rotation of a rotating shaft, and controls an angle of rotation of a rotating shaft based on the detected angle of rotation. The pulse generator generates the pulse signal in the initialization pattern, which indicates the position of origin of the angle of rotation, in accordance with the rotation of the DC motor. If a determination means determines that it is impossible to detect the pulse signal in the initialization pattern when the DC motor is rotated in a first direction, the CPU rotates the DC motor in a second direction.
