第３項記載の可動ミラー装置。[Scope of claim for utility model registration] ゛ 1. A movable mirror and a movable mirror that can move back and forth.
a mirror drive mechanism that drives from the observation position to the photographing position by forward movement and from the photographing position to the observation position by backward movement;
The rotary member is rotatably supported on a rotating shaft and has a rotating member that rotates in conjunction with the mirror drive mechanism so as to slow down at least the forward movement speed of the mirror drive mechanism, and an action portion that can come into contact with the drive mechanism. , a bounce prevention member rotatably supported on the rotation shaft of the rotating member; a bounce prevention lever driving means for rotating the bounce prevention member by forward movement of the mirror drive mechanism; and completion of movement of the movable mirror to the photographing position. At approximately the same time, by stopping the bounce prevention member, the bounce of the backward force of the drive mechanism is restricted by the action part in a state where the direction connecting the action part and the rotating shaft substantially coincides with the bounce direction of the drive mechanism. A movable mirror device comprising a stopper. 2. The utility model according to claim 1, wherein the bounce prevention member is connected to the rotating member via a friction means or a friction means so as to be interlocked with the rotation of the rotating member. Movable mirror device. 3. The mirror drive mechanism includes a first drive member linked to the rotation member and driven in forward and backward directions by a drive means, and a first drive member that moves the movable mirror between an observation position and a photographing position. a movably held mirror holding member, connected to the mirror holding member, capable of being held to the bounce prevention member, and interlocking with the forward movement of the first driving member only when the first driving member moves forward; and a second driving member that moves back and forth, and the bounce prevention member is configured to move in conjunction with the return movement of the first drive member and retreat from a position that prevents the second drive member from moving back. The movable mirror device according to claim 1 or 2 of the utility model registration claim, characterized in that: - the first drive member includes a drive gear section; A gear member that meshes with the
The movable mirror device according to claim 3, characterized in that the movable mirror device comprises a flywheel coaxially integrally connected to the gear member.
