摘要： 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.

摘要： 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. The revolution preventing mechanism prevents revolution of the planetary gear in the release direction when the sun gear decelerates in a first direction and the input gear is driven by the planetary gear.

摘要： 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.

摘要： 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. The rotation transmitting element is designed with its center of gravity located so that the rotation transmitting element will, through the centrifugal force accompanying the rotation of the rotatable drive member, pivot in the direction that will cause the first and second engagement elements to engage only upon rotation of the rotatable drive member in the one direction.
