Housing and control unit for underwater camera

摘要

An underwater camera housing for enclosing a camera for use with a flash unit has a cable connector to which a signal-transmitting cable extending to the flash unit is attached and a link switch is provided on its outer surface by which the transmission of signals through the cable can be cut off or connected again. The signal transmitted through the cable may be electrical signals or light signals. If light signals are transmitted from the housing to control the flash unit, a circuit is provided for generating an electrical signal to prepare the camera for flash photography and the link switch serves to control the generation of this electrical signal such that the camera can be prepared selectively either for flash or natural-light photography.
