Photographic camera having automatic exposure control of the type in which the shutter speed is selected by the operator, the operation of the shutter release being prevented when the scene brightness is excessive or insufficient for proper exposure at the selected shutter speed. The electric circuit of the camera consists of a photoelectric element, a galvanometer and a plurality of resistors each having a resistance corresponding to a shutter speed and selectively connected to the circuit in c...

Photographic camera having a flash synchronizing device operable in X-contact and M-contact synchronization photography. The camera has a pair of electric terminals each connected to the X-contacts and the M-contacts of the flash synchronizing device. The pair of electric terminals are embedded in the accessory shoe of the camera spaced apart from each other in such positions that, when an electronic flash device having an electric contact thereof in its mounting foot is attached to the accessor...

A coupling device comprises a pair of coupling channels formed in the both lateral sides of a compact cassette tape recorder, and a pair of rails formed on a part of a radio set for engagement with the channels, allowing the cassette tape recorder to be detachably coupled with the radio set. When not coupled, apertures provided in the tape recorder for connection terminals are covered by a coverplate, which uncovers these apertures by a sliding movement as the tape recorder is coupled with the r...
