ABSTRACT:
A control method can stop motor operation reliably when a mirror rotator is mechanically locked at a driven end of the mirror rotator. The control method operates a motor18according to battery voltage. The motor18is operated with an operating time set and is stopped after a lapse of the set operating time, where the operating time is a time required for the motor18to drive the mirror rotator14from the retracted position or the working position to the working position or the retracted position at which the mirror rotator14is locked by a stopper. The control method detects the battery voltage, and decreases the set operating time of the motor18when the detected battery voltage is high or increases the set operating time of the motor18when the detected battery voltage is low.
