<P>PROBLEM TO BE SOLVED: To provide a mirror device that can inhibit displacement of a mirror even when rocking the mirror through driving of a motor. <P>SOLUTION: When rocking the mirror to a registration position through driving of motors M1 and M2, the mirror device stops power supply to the motors M1 and M2, when the mirror rocks to a motor stop position which is short only a fixed angle rather than the registration position, after starting power supply to the motors M1 and M2 and making the mirror rock. Here, a stop position correction value is learned based on displacement of an actual stop position of the mirror and the registration position, while computing a stop position correction value based on the working voltage and the working current of the motors M1 and M2 which are detected through voltage sensors 11 and 21 and current sensors 12 and 22, and the motor stop position is corrected based on the stop position correction value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
