Patent number: 6184922Abstract: A camera control unit for processing a signal output from an imaging device incorporated in an endoscope is provided with an analog video signal output terminal through which a video signal is output to a monitor, and a digital video signal output terminal to which a still image-specific or motion picture-specific expansion unit is coupled in a freely detachable manner. By handling a release switch, a still image or motion picture can be recorded digitally. Even when the recorded image data is edited or subjected to any other processing, deterioration of image quality can be prevented. An imaging system having these advantages can be realized on a small scale.Type: GrantFiled: July 30, 1998Date of Patent: February 6, 2001Assignee: Olympus Optical Co., Ltd.Inventors: Katsuyuki Saito, Akihiko Mochida, Kotaro Ogasawara, Noboru Kusamura, Makoto Tsunakawa, Hideki Tashiro, Shinji Yamashita, Kanichi Matsumoto, Wataru Ohno, Masahiro Hagihara, Kazutaka Nakatsuchi, Kuniaki Kami

Patent number: 5469841Abstract: An endoscope apparatus comprising an electrical connector which is electrically connected to an electrical device such as a CCD in an organism inserting device such as an endoscope which has an inserting section inserted into a organism. The electrical connector is connected to an electrical connector receptacle such as a control unit after the organism inserting device has been disinfected and sterilized by disinfection liquid. Processing is first performed in which the liquid remaining in the vicinity of an electrical contact of the electrical connector is removed by a liquid removing mechanism and, thereafter, electrical operation occurs. Thus, generation of a short-circuiting accident is prevented.Type: GrantFiled: October 27, 1993Date of Patent: November 28, 1995Assignee: Olympus Optical Co., Ltd.Inventors: Kazunari Kobayashi, Kenji Omachi, Yutaka Tatsuno, Masahiro Hagihara, Atsuki Kidawara, Tadayoshi Hara, Nobuyoshi Yazawa
