摘要： In a slit exposure shutter having leading and trailing blades driven to run down to make an exposure and to return to their initial positions by an electromagnetic drive source, this source is provided with electromagnetically operated latch means for holding the leading and trailing blades in either one of the terminal ends of running down and returning movement thereof. Another feature is that the above-described latch means is constructed by utilizing the magnetic attraction force of at least one of the stationary and movable electromagnetic members of the drive source.

摘要： In the slit shutter disclosed, an actuator transmits the rotational force of an electromagnetic drive arrangement to move shutter blades through opening and closing cycles. A spring arrangement for engaging the actuating means serves to aid the shutter movement at the beginning of the cycle and retard the shutter movement at the end of each cycle while the spring arrangement is energized during its retarding action. According to an embodiment of the invention, the spring arrangement encounters an arm of the actuator at the end of each cycle, absorbs the arm movement during the retardation, and uses the energization to aid the movement at the start of the next cycle. The spring arrangement again encounters the arm at the end of the next cycle.

摘要： The present invention relates to the flash photographic system for camera which is characterized in that the system presents a safety device for preventing various misoperations generally apt to take place at the time of taking a photograph by using a flash light device. By means of the operation of this device, the shutter time is set at a certain determined time for taking a photograph under flash light with the shutter time setting means at the camera side whereby the flash light photographic mode setting signal can be obtained only when the light device is set at the state ready for flash lighting in such a manner that the camera is capable of taking a photograph under flash light only when this signal is obtained. According to a preferred embodiment in accordance with the present invention, even when the release operation is carried out so that the above mentioned flash light photographic mode setting signal is not obtained, the flash light device does not operate by means of the effect of the safety device so that the camera is automatically set in the state for taking photography under ordinary day light.
摘要翻译：本发明涉及一种用于相机的闪光摄影系统，其特征在于，该系统提供一种安全装置，用于防止通过使用闪光灯装置拍摄照片时通常易于发生的各种误操作。通过该装置的操作，将快门时间设定在用于在闪光灯下拍摄照片的确定时间，其中快门时间设定装置在相机侧，由此仅当闪光灯照相模式设定信号光装置被设置在准备闪光照明的状态，使得照相机仅在获得该信号时能够在闪光下拍摄照片。根据本发明的优选实施例，即使执行了解除操作以使得没有获得上述闪光照相模式设置信号，闪光灯装置也不会通过安全的作用而操作设备，使相机自动设置为在普通日光下拍摄的状态。

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.
摘要翻译：用于照相机的液晶显示装置包括具有用于提供照相信息的显示的液晶材料的显示部件和用于形成要拍摄的被摄体的图像的聚焦玻璃。掩模面向显示构件和聚焦玻璃，掩模包括面向显示构件的显示部分的第一透明部分和面对形成在聚焦玻璃上的物体图像的第二透明部分。在荫罩的第一透明部分和第二透明部分之间设置遮光部分，以使显示部件的端部从光线上遮光。该掩模使得相机中提供的取景器光学元件能够显示具有直视相机用户的矩形视野。这是通过在第一和第二透明部分和掩模的遮光部分之间形成边界线来实现的，其中每个边界线基本上形成具有位于垂直于长边和短边之一的直线上的中心的圆弧的视图字段，哪条线通过视图字段的中心。弧形边界线克服了取景器光学器件产生的变形，使得它们被视觉上被认为是直的。

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.
