Patent number: 7929858Abstract: An image-capturing element that receives light of a subject image entering within a camera body through an interchangeable photographic lens is packaged and is mounted at the camera body via a holder. A camera-side mounting surface and a holder-side mounting surface are machined in advance and formed respectively relative to the mounting surface for the photographic lens formed at the camera body and the light-receiving surface of the image-capturing element. By mounting the image-capturing apparatus with the camera-side mounting surface and the holder-side mounting surface placed in contact with each other at the camera body using screws, the light-receiving surface is aligned with the image-forming position of the photographic lens.Type: GrantFiled: September 8, 2004Date of Patent: April 19, 2011Assignee: Nikon CorporationInventors: Akira Ezawa, Keiji Osawa, Akira Yamamoto, Takayuki Uchiyama, Yousuke Kowno, Katsumasa Nishijima, Tomoyuki Takada

Patent number: 7671903Abstract: An electronic camera displays recorded information, such as image frames, to permit the selection of items of information to be transferred to external equipment. Each time an item of information is transferred, an informative indication (e.g., an icon) is displayed in association with the transferred item to confirm the transfer and to permit an operator to select items of recorded information that may be erased. If an error occurs during transfer of a series of items, the operator can determine from the display the point at which the error occurred, avoiding the need for transferring items that have already been transferred.Type: GrantFiled: July 20, 2006Date of Patent: March 2, 2010Assignee: Nikon CorporationInventors: Tomoaki Kawamura, Norikazu Yokonuma, Hirotake Nozaki, Akira Ezawa, Kazuyuki Kazami

Patent number: 7573526Abstract: By using a focal plane shutter having one set of shutter blades as a shielding member of an image pick-up element, it is possible to miniaturize the shutter compared to a focal plane shutter having two sets of blades. This enables the operation to be simplified, and also saves space. Furthermore, in an electronic camera having this focal plane shutter, because the shooting lens side of the image pick-up element that is disposed in the main camera body can be disposed protruding into the shutter unit, the length of the main camera body in the direction of the optical path of the shooting lens can be reduced, and it is possible to form the main camera body small compared to a conventional main camera body.Type: GrantFiled: October 21, 2003Date of Patent: August 11, 2009Assignee: Nikon CorporationInventor: Akira Ezawa

Patent number: 5956537Abstract: A film feeding device for a camera uses first and second electric motors associated with first and second planetary gearing mechanisms, respectively. In one embodiment, the first motor and first planetary gearing mechanism drive a spool shaft of a film cartridge to supply film to a winding spool. The winding spool is driven by the second motor and second planetary gearing mechanism to wind film onto the winding spool, at which time the first motor is stopped and the first planetary gearing mechanism is automatically disconnected from the spool shaft. For rewinding, the second motor is operated in reverse and the second planetary gearing mechanism is automatically disconnected from the winding spool and connected to the spool shaft of the film cartridge.Type: GrantFiled: January 14, 1998Date of Patent: September 21, 1999Assignee: Nikon CorporationInventors: Tsutomu Wakabayashi, Koichi Daitoku, Akira Ezawa

Patent number: 5628041Abstract: A film supply device that accurately stops the film in a short length of time at a predetermined position even when using increased film supply speed. A film supply device includes a motor and a transfer mechanism. The transfer mechanism has an input gear rotated by the motor and that transfers the input gear rotation to a winding shaft for the film. The film supply device further includes a revolution preventing mechanism and a planetary clutch mechanism having a sun gear and a planetary gear. The sun gear is rotated by the motor. The planetary gear revolves about the sun gear and is rotated by the sun gear. The planetary gear enmeshes with the input gear and revolves in a connected direction when the sun gear rotates in a first direction. The planetary gear is separate from the input gear and revolves in a release direction when the sun gear rotates in a second direction.Type: GrantFiled: September 28, 1995Date of Patent: May 6, 1997Assignee: Nikon CorporationInventor: Akira Ezawa

Patent number: 5560460Abstract: A one-way clutch includes a first engagement element of a rotation transmitting element that is attached to a rotatable drive member. The first engagement element is forced toward a second engagement element that is attached to near the center or to the radially inner perimeter of an annular outer edge of a driven member. When the drive member rotates in one direction, the first and second engagement elements connect and the rotation of the rotatable drive member is transmitted to the rotatable driven member. The rotation transmitting element is connected to the drive member in a manner that allows it to rotate freely and so that the first engagement element may separate from or connect to the second engagement element.Type: GrantFiled: December 7, 1994Date of Patent: October 1, 1996Assignee: Nikon CorporationInventor: Akira Ezawa
