Patent number: 7400827Abstract: According to the present invention, light from a taking lens is reflected by a quick return mirror in a lateral direction of a body unit. Then, after passing through a screen, the light is reflected toward an upper side of the body unit by a second mirror except part of the light. The light reflected by the second mirror is reflected by a third mirror in a direction opposite to a direction in which the light is reflected by the quick return mirror, and is further reflected by a fourth mirror toward an eyepiece located on a back side of the body unit. Part of the light which passing though the screen is taken by an AF sensor unit provided in rear of the second mirror, and an image formation position of an optical image is detected.Type: GrantFiled: August 26, 2005Date of Patent: July 15, 2008Assignee: Olympus CorporationInventors: Sumio Kawai, Yoichi Washizu, Koji Kato, Shigeru Iwase, Hiroshi Terada, Shigeru Kato

Patent number: 6195181Abstract: An image reading apparatus in accordance with the present invention is an apparatus capable of reading an image from a transmissible original or reflective original. A lens unit and line sensor are located on one side of an original feed path. A tubular lamp movable to a position opposite to the lens unit with respect to the feed path and to a position on the side of the lens unit is included. The type of inserted original is judged by an original detector located near an original insertion port. If the inserted original is a transmissible original, the tubular lamp is moved to the position opposite to the lens unit. If the inserted original is a reflective original, the tubular lamp is moved to the position on the side of the lens unit. Furthermore, the power of the lens unit for projection is automatically adjusted in line with the type of original. In the case of the image reading apparatus, the way of handling is easy, the design is compact, and the cost can be reduced.Type: GrantFiled: June 18, 1998Date of Patent: February 27, 2001Assignee: Olympus Optical Co., Ltd.Inventor: Yoichi Washizu

Patent number: 5973729Abstract: An image input device capable of: reading images on 35 mm film and images on another type of film contained in a new photo system-adapted cartridge; converting the images into digital image signals; and, feeding the signals into a computer. The device is constructed in such a manner that one selected between film adaptors (100, 300) can be loaded in a groove portion (2) of a main device body. The film adaptor (100) can retain 35 mm film (401, 402), while the film adaptor (300) can retain a new photo system-adapted cartridge film (403). The images on the loaded film are read by a linear CCD image sensor (9) being caused to execute scanning. This scanning results in the digital image signals which then are fed into a computer and the like.Type: GrantFiled: November 14, 1996Date of Patent: October 26, 1999Assignee: Olympus Optical Co., Ltd.Inventor: Yoichi Washizu
