    摘要： A photographic optical system (1) is described having a cam ring (14) with at least one groove (20, 21) therein, said cam ring (14) being rotatable at a constant axial position, and said system (1) further having at least one movable lens barrel (22, 23, 24, 25, L1) movable along an optical axis of said photographic system (1) in association with rotation of said cam ring (14). Said system (1) having at least one light intercepting member (210, 220) positioned about the periphery of said cam ring (14), said member (210, 220) thereby comprising means (211, 90) for covering each said camming groove (20, 21) and for preventing light from entering the interior of said cam ring (14). In an embodyment of the Invention at least one light intercepting member (220) is positioned in a space (W) between a front end of a cam ring support (13) and there is a front cover (200) having an opening (201) through which said lens barrel (22, 23, 24, 25, L1) is adapted to move. In a further embodyment of the invention said light intercepting member (210) comprises a flexible code plate (90) wrapped about one peripheral portion of said cam ring (14), a light intercepting tape (211) positioned about a second peripheral portion of said cam ring (14), and an annular gear (15) positioned about a third peripheral portion of said cam ring (14). A camera comprising such a photographic optical system (1) is described, which is in one embodyment of the invention automatically focussed in accordance with the distance of a subject from a film plane in said camera.

    摘要： A Guide mechanism of a flexible printed circuit board is discribed for a lens shutter type of camera having a lens barrel block (1) comprising an axially movable lens barrel (22), comprising a shutter block (23) being attached to said lens barrel (22), and comprising means (160, 161, 162) for conducting camera operational signals from a camera body to said shutter block (23). In accordance with the invention said conducting means (160, 161, 162) comprising a flexible printed circuit board (160) and said camera having a guide plate (163) for said flexible printed circuit board (160), said guide plate (163) comprising means (165, 168, 169) for guiding movemet of said flexible printed circuit board (160) as said lens barrel (22) moves axially. In an embodyment the camera additionally comprises an anti-reflection device (171) attached to said flexible printed circuit board (160). Said device (171) comprises an anti-reflection layer attached to at least one surface of said FPC board (160), said at least one surface being located adjacent to the optical axis of said photographic lens assembly (1) when said board (160) is attached to said shutter block (23). In an further embodiment of the invention said device (171) comprises an anti-reflection coating secured to said at least one surface of said FPC board. The camera further comprising means for decoding said lens positional information on said plate (90) into focal length or lens opening information.
