摘要： A lens cap opening and closing mechanism (30) adapted to be used with a lens support frame (22) having an outer periphery, a central aperture (22b), and at least one barrier plate (31) for selectively closing said central aperture (22b). Said mechanism (30) comprising a movable member (36, 138) positioned in a peripheral opening (39) of said frame (22), said member (36, 138) being further engaged with said at least one barrier plate (31). Said mechanism further having means (38, 141) for selectively moving said member (36, 138) inwardly of said frame to close said aperture (22b) with said at least one barrier plate (31). Said movable member (36, 138) engages said barrier plates (31) via two resilient Y-shaped drive arms (34) which have forked ends (34a) which receive pins (33) attached to said barrier plates (31) or said movable member (138) engages said barrier plates (31) via two driving arms (136) which have free ends (136a) abutting pins (133) on respective barrier plates (31). Said camera further comprising a driving motor (5) for driving said zoom lens (L1) into said collapsed lens position.
