<p>A camera includes a movable mirror (16) which is movable between a finder-viewing position and an exposure-retracted position, a spring member (14) for applying to the movable mirror a force for causing the movable mirror to move from the finder-viewing position to the exposure-retracted position, a movement mechanism (11,12) for causing the mirror to move, and a submirror (25) which is movable with respect to the movable mirror and is located in a focus detecting position for reflecting subject light toward a focus detecting device when the movable mirror is located in the finder-viewing position. The submirror is interlockingly located in an exposure-retracted position when the movable mirror is in the exposure retracted position. The movement mechanism includes a cam member (8) arranged to be rotated by a drive source (7), and a cam follower which is in abutment with the cam member. During motion of the cam follower in a first direction, the movable mirror is caused to move towards the exposure-retracted position by means of the urging force of the spring member. During motion of the cam follower in a second direction, the movable mirror is caused to move towards the finder-viewing position against the urging force of the spring member. <IMAGE></p> |
