Abstract: 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.

Abstract: A zoom lens for a camera having a between-the-lens shutter includes a motor for moving the lens along an optical axis in forward and rearward directions. A switch is operable by an operator to control operation of the motor for moving the lens from an initial position on the axis to a final stationary position that establishes the focal length of the lens. Control apparatus is responsive to the setting of the switch for operating the motor such that movement of the lens from its initial position to its final position always ends after the lens travels to its final position in a predetermined direction.

Abstract: A method of controlling the focusing of a zoom lens which has a plurality of lens groups including at least one focusing lens group, wherein an amount of deviation from focus caused by a zoom operation is corrected by movement of the focusing lens group. The method includes setting a reference object distance, at which no deviation from focus occurs during zooming of the zoom lens, at a finite object distance, such that the amount of movement of the focusing lens group necessary to effect focusing is determined based upon a reference position corresponding to a position of the focusing lens group at the reference object distance, in accordance with focal length data and object distance data. The zoom lens assembly includes a stationary lens barrel and a rotatable cam ring which is supported on the stationary lens barrel for movement in the direction of the optical axis while being rotated, and which includes at least two cam grooves. The zoom lens includes first and third lens groups which are both movable by one of the two cam groups in a direction of an optical axis. A second lens group movable by a second of the two cam grooves in a direction of the optical axis is also provided, as well as a focusing mechanism for moving the second lens group to a position which is determined by focal length data derived from actual positions of the first, second, and third lens groups and object distance data detected by the object distance measuring device.

Abstract: A barrier mechanism of a camera includes a cylindrical lens cover which has an aperture at its front face and which is supported to move between a photographing position and an accommodating position to the rear of the photographing position. At least one barrier is provided on the front end of the lens cover to open and close the aperture. A barrier opening and closing mechanism which opens and closes the barrier in association with the rotation of a cam ring is further provided. The barrier opening and closing mechanism includes a spring for biasing the barrier towards an open position, and an opening and closing pin which can be moved radially with respect to the lens cover. The pin closes the barrier when moved in the radial direction, and a closing lever is located at a predetermined position outside the lens cover and is biased to rotate to continuously press the opening and closing pin to close the barrier. The cam ring is located to normally prevent contact between the closing lever and the opening and closing pin. The cam ring is provided with an opening which permits the closing lever to rotate toward the opening and closing pin when the lens cover is moved to the accommodating position.

Abstract: A camera has a camera body, an interchangeable lens engageable with the camera body, and a rotatable diaphragm setting ring on the lens. A first mounting member on the camera body interlocks with a second mounting member on the lens to engage the lens with the camera body. A hole is formed in the second mounting member adjacent to the first mounting member and a slideable lock pin is disposed in the hole. The ring is rotatable between an automatic diaphragm control position and a range of diaphragm preset positions. Responsive to the diaphragm setting ring, the pin is retracted to a position approximately flush with the surface of the second mounting member when the diaphragm setting ring is within the range of diaphragm preset positions and the lock pin is extended outwardly from the surface of the second mounting member to the region occupied by the first mounting member when the diaphragm setting ring is at the automatic diaphragm control position. In camera bodies with automatic diaphragm control, the first mounting member has a recess aligned with the hole in the second mounting member to receive the pin in its extended position. In camera bodies without automatic diaphragm control, the first mounting member has a surface abutting the hole in the second mounting member to prevent the lock pin from extending therefrom, thereby blocking rotation of the diaphragm setting ring into the automatic diaphragm control position.
