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.
摘要翻译：通过使用具有一组快门叶片作为图像拾取元件的屏蔽构件的焦平面快门，与具有两组叶片的焦平面快门相比，可以使快门小型化。这样可以简化操作，并节省空间。此外，在具有该焦平面快门的电子照相机中，由于设置在主相机主体中的图像拾取元件的拍摄透镜侧可以设置成突出到快门单元中，所以主相机主体的长度在可以减少拍摄镜头的光路的方向，并且与传统的主相机主体相比，可以使主机相机体形成小。

摘要： A power focus device for a camera provides a user-friendly lever interface allowing efficient camera operation. A lever, located outside a camera cover, is movable in two opposing directions but is biased to remain at a neutral position between two extremes of movement. Moving the lever from the neutral position initiates driving the camera lens to focus in either a first or a second direction according to a direction of a displacement of the lever from the neutral position. A speed of focusing is proportional to an amount of displacement of the lever from the neutral position, thus permitting variable high and low speed focusing in both directions for rapid and accurate close-up and infinity focussing. Incorporating a seal into the device permits use in underwater camera applications.
摘要翻译：相机的电源对焦设备提供了一个用户友好的手柄接口，从而实现高效的相机操作。位于相机盖外部的杠杆可在两个相对的方向上移动，但是被偏置以保持在两个极限运动之间的中间位置。将杠杆从中立位置移动，根据杠杆从中立位置的位移方向开始驱动相机镜头朝第一或第二方向聚焦。聚焦速度与杠杆从中立位置的位移量成比例，从而允许双向可变的高速和低速聚焦，以实现快速准确的特写和无限远聚焦。将密封件装入设备允许在水下摄像机应用中使用。

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： Light emitted from a taking lens 20 enters a first birefringent plate 1a to be spatially divided along a first direction extending perpendicular to the direction in which the light advances to achieve two separate rays L10 and L20. The vibrational planes of the two light fluxes L10 and L20 emitted from the first birefringent plate 1a are converted to a circularly polarized light by a phase plate 1c. The two light fluxes L10′ and L20′ emitted from the phase plate 1c are each spatially divided into two by a second birefringent plate 1d along a second direction extending perpendicular to the first direction to achieve four separate rays L11, L12. L21 and L22, to be guided to an imaging plane 15a of an imaging device 15. At least either the first birefringent plate or the second birefringent plate is constituted of lithium niobate, rutile, Chilean nitrate, or the like.
