ABSTRACT:
A lens carrier damping device is provided in a camera having a lens carrier that is selectively movable between two alternate positions to change a parameter of the camera's optical system. The two positions of the lens carrier are established by its operative engagement with respective abutment surfaces under the influence of bidirectional spring means that bias the lens carrier in the direction of its movement during the final portion of its movement toward contact with either of the abutment surfaces. The damping device is bidirectionally operable and is adapted to retard the final movement of the lens carrier to thereby cushion its impact against the abutment surface with which it is brought into contact by the spring means. In accordance with a preferred embodiment of the invention, the damping device comprises an arm that is pivoted by the final movement of the lens carrier in opposition to a retarding force exerted on the arm by a viscous substance between the relatively movable bearing surfaces of the arm supporting bearing structure.
