ABSTRACT:
Various movable mirrors are arranged within a camera for shifting operation by a lifting mechanism and are provided with a mechanism for promptly settling the movable mirror on its return to an original position from a shifted position. The mechanism includes an antibounce member and when the mirror is forcedly shifted in response to an operation of the camera, the position of the member is biased to the outside of the moving locus of the mirror and upon return of the mirror to its original position, the member is released from the biased state and comes within the moving locus of the mirror to prevent rebound thereof.
