Abstract
A mirror driving device includes a lead screw configured to be driven by a drive source, a mirror member configured to be movable between a mirror-down position and a mirror-up position, a mirror driving member configured to rectilinearly move to drive the mirror member between the mirror-down position and the mirror-up position, and a restriction unit configured to switch between a restriction state that restricts a rectilinear movement of the mirror driving member and a restriction release state that releases the restriction state. The restriction unit switches between the restriction state and the restriction release state without allowing the mirror driving member to rectilinearly move when the mirror member is in the mirror-up position or the mirror-down position, and the mirror driving member rectilinearly moves in conjunction with driving of the lead screw after the restriction unit switches from the restriction state to the restriction release state.
