Publication number: 20040033070Abstract: 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: ApplicationFiled: July 10, 2003Publication date: February 19, 2004Applicant: PENTAX CorporationInventors: Keisuke Haraguchi, Shinsuke Kohmoto, Takeo Kobayashi, Shigeru Kondoh, Hideki Ohkubo, Norio Numako, Saburo Sugawara

Patent number: 5966551Abstract: 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 as 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: April 22, 1997Date of Patent: October 12, 1999Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Keisuke Haraguchi, Shinsuke Kohmoto, Takeo Kobayashi, Shigeru Kondoh, Hideki Ohkubo, Norio Numako
