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 motoraccording to battery voltage. The motoris 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 motorto drive the mirror rotatorfrom the retracted position or the working position to the working position or the retracted position at which the mirror rotatoris locked by a stopper. The control method detects the battery voltage, and decreases the set operating time of the motorwhen the detected battery voltage is high or increases the set operating time of the motorwhen the detected battery voltage is low.
