Aperture/shutter mechanism with damping member.

摘要

An aperture/shutter mechanism includes one or more shutter blades (66) moveable to various aperture openings between a fully open and closed position. At least one damping member (34,38) has a damping surface in continuous frictional contact with at least a portion of a surface of the one or more shutter blades (66) to substantially prevent oscillation of the one or more shutter blades during movement to the various aperture openings between the fully open and closed positions. <IMAGE>
