Abstract: PROBLEM TO BE SOLVED: To provide a technology for a mirror drive device, whereby when a mirror is driven and brought to a predetermined position by a positioning member, vibration of the mirror resulting from striking of the mirror against the positioning member, can be speedily converged by a simple configuration.
SOLUTION: In a mirror box (mirror drive device) 103 having a main mirror 103a and a sub-mirror 103b, a mirror down position and a mirror up position can be switched for the sub-mirror 103b by driving the sub-mirror holder 1032. In the mirror down position, a metal stopper Sb comes into contact with a magnet plate PM disposed on the sub-mirror holder 1032. In such a configuration, vibration of the sub-mirror 103b, resulting from striking of the sub-mirror 103b against the stopper Sb when the sub-mirror is driven to the mirror down position, can be speedily converged using a magnetic attraction force acting between the magnet plate PM and the stopper Sb.
