Patent number: 5598240Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: January 28, 1997Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Keisuke Haraguchi, Shinsuke Kohmoto, Takeo Kobayashi, Shigeru Kondoh, Hideki Ohkubo, Norio Numako, Saburo Sugawara

Patent number: 5583596Abstract: 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).Type: GrantFiled: June 3, 1995Date of Patent: December 10, 1996Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Keisuke Haraguchi, Shinsuke Kohmoto, Takeo Kobayashi, Shigeru Kondoh, Hideki Ohkubo, Norio Numako, Saburo Sugawara, Susao Nakamura, Hirofumi Matsuo, Katsuhiko Nomura, Etsuro Nishio, Haruo Ishii

Patent number: 5363164Abstract: An electronically controlled camera having a macro mode operating capability which is disabled in the event predetermined object-distance-information is not obtained which is required for automatically focusing the camera in the macro mode. In this event, the lens is automatically shifted from the macro position to a non-macro position to enable a properly focused photograph to be taken. The shifting of the lens is preferably performed in response to actuation of the shutter release button while the lens is in the macro position, without further actuation of the shutter release button. Further, the camera can be arranged to return the lens to a macro position after the photograph is taken.Type: GrantFiled: September 21, 1993Date of Patent: November 8, 1994Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Takeo Kobayashi, Yasushi Tabata, Norio Numako, Katsutoshi Nagai, Takao Nishida

Patent number: 5257053Abstract: A position detecting arrangement for detecting the position of a movable member relative to a reference position. The arrangement is particularly adapted for use in connection with electronically controlled cameras which include a zoom lens and includes a code information carrier which is able to transmit information indicative of a plurality of codes, at least one of the codes being used a plurality of times for identifying more than one position of the zoom lens, i.e., more than one focal length of the lens. The use of such "relative" codes permits the camera to be made more compact. However, the disclosed invention includes an arrangement for retaining a given number of "position" codes which correspond to the actual position of the lens, to thereby enable the camera to retain a given degree of accuracy in its object-distance-measuring unit for focusing the zoom lens.Type: GrantFiled: April 30, 1992Date of Patent: October 26, 1993Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Takeo Kobayashi, Yasushi Tabata, Norio Numako, Katsutoshi Nagai

Patent number: 5241334Abstract: An electronically controlled camera having a zoom lens has an operational member for driving the zone lens between a tele position and a wide angle position. The zoom lens is moved toward the tele position when the operational member is moved in a normal direction. The zoom lens is moved toward the wide angle position when the operational member is moved in the reverse direction. A taking mode changing mechanism changes taking modes. A display device displays a taking mode. A control mechanism changes the taking mode to another taking mode when the taking mode changing mechanism is operated. A setting time changing device changes the setting time of a manual shutter (or interval) to another setting time under predetermined conditions when the camera is set in a manual shutter mode (or interval) and both the operational member and the taking mode changing mechanism are operated.Type: GrantFiled: August 29, 1991Date of Patent: August 31, 1993Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Takeo Kobayashi, Takao Nishida, Yasushi Tabata, Norio Numako, Katsutoshi Nagai
