Abstract:
1. A movable mirror shock-absorbing mechanism of a camera, comprising: a movable mirror which is supported to be rotatable between a viewfinder light-guiding position, in which said movable mirror is positioned in a photographing optical path to reflect incident light from an object toward a viewfinder optical system, and a retracted position, in which said movable mirror is retracted from said photographing optical path to allow said object light to travel toward a photographic light-receiving medium; a mirror-retracting shock-absorbing member which comes into contact with, and is pressed and moved in a first pressing-moving direction by, said movable mirror to absorb shock of said movable mirror when said movable mirror rotates from said viewfinder light-guiding position to said retracted position; and a mirror-advancing shock-absorbing member which is held in a limit position in which a range of movement of said mirror-retracting shock-absorbing member in a direction opposite to said first pressing-moving direction is limited when said movable mirror is in said retracted position, wherein said mirror-advancing shock-absorbing member comes into contact with, and is pressed and moved in a second pressing-moving direction by, said movable mirror from said limit position to release the limitation of said range of movement of said mirror-retracting shock-absorbing member and to absorb shock of said movable mirror when said movable mirror rotates from said retracted position to said viewfinder light-guiding position.
