摘要： In the disclosed viewfinder, a focusing plate receives light from an objective via a reflex mirror, and after focusing, passes light to an eyepiece via a penta prism. A by-pass optical system receives light from outside the view field of the viewfinder and directs the light through an information carrier outside the optical path of the photographic light and into the penta prism so that the information can be displayed close to the view field of the viewfinder.

摘要： A liquid crystal display device for a camera includes a display member having liquid crystal material for providing a display of photographic information, and a focusing glass for forming an image of an object which is to be photographed. A mask is arranged to face the display member and the focusing glass, the mask including a first transparent part which faces a display part of the display member, and a second transparent part which faces the object image formed on the focusing glass. A light shading part is provided between the first and second transparent parts of the mask to shade an end part of the display member from light. The mask enables view finder optics provided in the camera to display a rectangular view field having straight sides to the camera user. This is accomplished by forming boundary lines between the first and second transparent parts and the light shading part of the mask, wherein each boundary line substantially forms an arc having a center located on a straight line which is perpendicular to one of a long and short side of the view field, and which line passes through the center of the view field. The arcuate boundary lines overcome distortion produced by the view finder optics so that they are visually recognized as being straight.

摘要： A liquid crystal cell of elongated shape adapted to be arranged at one side of the field of view of the camera finder has a plurality of opposing of transparent electrodes on opposite sides of a liquid crystal layer which are aligned to each other in a matrix form, whereby the necessary number of leads is reduced. In order for the liquid crystal layer to present an indication in a selected area, or areas, an alternating voltage is applied across the correspondingly aligned electrodes, while still preventing the above-identified alternating voltage to appear at two or more electrodes in one set simultaneously even when light is blocked in the two separated areas of the liquid crystal layer. In other words, the number of those of the plurality of electrodes in set to which the alternating voltage is applied at a time depending upon the exposure value is limited always to only one even when two separated areas are selected for light shuttering at a time. Thus, the exposure values or shutter times can be indicated in half-steps increments.
摘要翻译：细长形状的液晶单元适于布置在相机取景器的视场的一侧，在液晶层的相对侧上具有多个以矩阵形式彼此对准的多个相对的透明电极，从而减少必要数量的引线。为了使液晶层在所选择的区域或区域中呈现指示，跨越对应的对准的电极施加交流电压，同时仍然防止上述的交流电压同时出现在一组中的两个或更多个电极上即使在液晶层的两个分离区域中的光被阻挡时也是如此。换句话说，即使当一次选择两个分开的区域以进行光快门时，根据曝光值一次施加交流电压的多个电极中的多个电极的数量总是仅限于一个。因此，可以以半步增量指示曝光值或快门时间。

摘要： In the disclosed circuit, an electromagnetically driven shutter is opened and closed by an electromagnetic drive device. A detector senses the current through or the voltage across an exciting member of the electromagnetic drive. A drive circuit is controlled by a comparator which compares the output of a constant voltage source with the output of the detector. The drive circuit is regulated so that when the shutter is opened and closed, the current is maintained at predetermined values so as to always keep the shutter characteristics constant.

摘要： In the drive system disclosed, a first power source supplies a driving current to drive a moving member of an electromagnetic shutter driving device in one direction or in the reverse direction a second power source device consisting of a DC booster circuit, a capacitor, etc.; a photo-to-electric converter circuit discerns the brightness level of an object to be photographed and controls the outputs of the first and second power source devices to shift between these two outputs. An automatic change-over supplies the output of the second power source to the electromagnetic shutter driving device when the level of the output of the photo-to-electric converter circuit is equal to or above a predetermined level and supplies the output of the first power source to the electromagnetic shutter driving device when the output level of the photo-to-electric converter circuit is lower than the predetermined level.
