Patent number: 4614416Abstract: A device for controlling the operation of a camera includes a speed governing member arranged to be operated by a driving force differing from a driving force used for driving shutter blades. The opening speed of the shutter blades is stably controlled by the speed governing member. The control device retards the speed of a shutter blade opening action to enable an automatic focusing action to be performed before the photo-taking aperture actually begins to open after commencement of the shutter blade opening action.Type: GrantFiled: June 27, 1985Date of Patent: September 30, 1986Assignee: Canon Kabushiki KaishaInventors: Toyotosi Suzuki, Toru Nagata

Patent number: 4479705Abstract: A spool drive type camera in which the taking up of the film is carried out only by the rotative force of the spool, while the one-frame advancement of the film is controlled by the revolution of the sprocket as it is driven by the film transportation is provided with automatic switching means for selection of a mode in which the above-described one-frame advancement is effected by the rotative force of the winding up system when a film is not loaded in the above-described camera.Type: GrantFiled: January 19, 1983Date of Patent: October 30, 1984Assignee: Canon Kabushiki KaishaInventors: Hideo Tamamura, Mutsuhide Matsuda, Toyotosi Suzuki, Takashi Endo

Patent number: 4417795Abstract: In the disclosed automatic focus detection device, two image forming lenses have optical axes fixedly spaced a predetermined distance. Distance measuring elements are arranged near the focal points behind each image forming lens. A holding member holding one of the distance measuring elements is rotated around a shaft outside of the space between the optical axes of the two lenses so as to alter the distance between the distance measuring element and the image forming lens. According to an embodiment, one of the measuring elements is a light source which scans the object through one of the lenses when the holding member is rotated. Rotation of the holding member refocuses the light source throughout its scan.Type: GrantFiled: April 2, 1982Date of Patent: November 29, 1983Assignee: Canon Kabushiki KaishaInventors: Shuichi Tamura, Toyotosi Suzuki, Hideo Tamamura, Mutsuhide Matsuda

Patent number: 4351598Abstract: In a camera using 35 mm cartridge-contained film and having incorporated therein an automatic winding and rewinding mechanism, between the cartridge chamber arranged along one of the shorter sides of the exposure aperture of the camera and the outer side panel of the camera housing there are arranged an Albada type finder and a battery chamber capable of accommodating penlight (size AAA) batteries, in superimposed relation, while along the other shorter side of the exposure aperture there is arranged a film takeup chamber. The film advancing and shutter charge mechanisms are arranged in a space between the lower or longer side of the exposure aperture and the bottom panel of the camera housing. The film footage and release mechanisms are arranged in a space between the upper longer side of the exposure aperture and the top panel of the camera housing.Type: GrantFiled: April 10, 1981Date of Patent: September 28, 1982Assignee: Canon Kabushiki KaishaInventors: Toyotosi Suzuki, Hideo Tamamura, Mutsuhide Matsuda

Patent number: 4200371Abstract: A manually operable or automatic film speed setting system adapted for use in an electronic exposure control apparatus of a photographic camera. When a film cartridge having an electrically conductive marker representative of the sensitivity of film therein is loaded in the camera, information representative of film speed is automatically introduced into the exposure value computer regardless of the manually switched position of the inherent film speed dial different from that for the sensitivity of the used film.Type: GrantFiled: October 12, 1977Date of Patent: April 29, 1980Assignee: Canon Kabushiki KaishaInventors: Ryoichi Suzuki, Tetsuya Taguchi, Toyotosi Suzuki, Noriaki Sanada, Nobuo Tezuka, Takashi Uchiyama

Patent number: 4179203Abstract: A camera having a data recording device wherein there are provided an optical path for photographic insertion of data and an optical path for displaying data. Each of these optical paths has a light inlet disposed, independently of the other, in the same light flux emitted from a data source. Photographing data are photographically applied to a film surface and are also displayed inside a view finder by means of a data signal of light which is introduced directly into each of the optical paths.Type: GrantFiled: November 17, 1976Date of Patent: December 18, 1979Assignee: Canon Kabushiki KaishaInventors: Michio Hirohata, Toyotosi Suzuki, Hideo Yokota, Mutsuhide Matsuda, Tetsuya Taguchi, Noriaki Sanada
