摘要： A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photgraphic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.

摘要： An automatic film winding device in a camera in which a camera winding coupling is coupled to a motor drive side through a power transmission mechanism having a cam and a follower. The device comprises a cam system having a first cam for maintaining a motor drive circuit energized and a second cam for a film winding operation in said camera. After a release operation in the camera the motor drive circuit is energized in association with restoration of a camera release button or a shutter. The follower is displaced to the first cam by the relative motion of said first cam and follower caused by the further rotation of said motor, to maintain the motor drive circuit energized. After the completion of winding operation in the camera, the second cam is disengaged from the follower by the relative motion of the second cam and follower to deenergize the motor drive circuit.
摘要翻译： 一种照相机中的自动胶片卷绕装置，其中相机绕组联轴器通过具有凸轮和从动件的动力传递机构联接到电动机驱动侧。 该装置包括凸轮系统，该凸轮系统具有用于维持马达驱动电路通电的第一凸轮和用于在所述相机中进行薄膜卷绕操作的第二凸轮。 在相机中的释放操作之后，电动机驱动电路与相机释放按钮或快门的恢复相关联地被通电。 由于所述电动机的进一步旋转所引起的所述第一凸轮和跟随器的相对运动，从动件被移位到第一凸轮，以保持电动机驱动电路通电。 在相机中的卷绕操作完成之后，第二凸轮通过第二凸轮和跟随器的相对运动而从跟随器脱离，以使马达驱动电路失电。

摘要： A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.
