摘要： A slit exposure shutter having the front and rear screens thereof respectively arranged to be driven by a source of an electromagnetic driving force is provided with a minimum slit width insuring means which prevents uneven exposure resulting from difference in travelling speed between the front and rear shutter screens during a high speed shutter operation and particularly prevents a total absence of the slit, the shutter is also provided with a nullifying means which nullifies the insuring means when the shutter screens are on their return travels.

摘要： A single lens reflux camera of the type in which actuation of a first electromagnet causes sequential operation of the diaphragm, mirror and shutter, and in which the start of the opening operation of the shutter is followed, after an electronically timed interval, by actuation of a second electromagnet which controls closing operation of the shutter. In one embodiment, a device for preventing faulty operation of the shutter includes a voltage detector responsive to the drop of voltage of a battery below a satisfactory operating level for preventing the first electromagnet from being actuated when the shutter button is depressed, and an arresting mechanism arranged upon detection of abnormal operation of the second electromagnet at the start of operation of the mirror to stop a mirror drive means from further movement which would otherwise cause actuation of the shutter release.

摘要： A mirror box formed of metal serves as a metallic portion constituting together with a plastic portion an essential part for imparting strength characteristics to a camera body. The metallic portion is provided with a base for a lens mount and with similar parts for assembling other element. During molding, some of the metallic segments of the lens mount base are inserted as a framework into the plastic portion so that the metallic and plastic portions are constructed in the form of a unit. This unit is then assembled with other portions as the base unit of the essential part to complete a single lens reflex camera body.

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： 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.
