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： Disclosed is a single lens reflex camera having an electrically driven focal plane shutter. A locking arrangement locks the shutter curtains in their start positions before shutter release to prevent unintentional actuation of an exposure due to faulty operation of switches, shock, or the like. Upon completion of the upward movement of the quick return mirror, the locking mechanism is disabled.

摘要： A camera having an electromagnetic driving source for operating a focal plane shutter in the camera, includes a shutter base plate and a driving arm pivoted on the base plate for swinging movement in a plane parallel to the plate. A group of thin shutter blades are supported on the driving arm parallel to the surface of the base plate. The output shaft of a motor is coupled with the driving arm, and either one of the rotor of the motor, or a permanent magnet forming a part of the stator of the motor, provides magnetic flux parallel to the axis of the output shaft, thereby causing the rotor to rotate the output shaft and drive the focal plane shutter.

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： In the disclosed camera, a switchover arrangement automatically shifts from an automatic exposure mode to a flash mode in response to a charge completion signal from a flash device. A line electrically connects a terminal capable of receiving the charge completion signal from the flash unit to the switchover arrangement. A switch connected to the connecting line applies a signal of a value corresponding to the charge completion signal from a signal source in the camera to the switchover arrangement to cause the latter to effect a switchover to the flash mode in response thereto in the same manner as when a charge completion signal is applied thereto.
