ABSTRACT:
A motor driven camera has a detachable drive unit, and includes a motor drive circuit which is activated for driving a film wind-up and shutter charge motor on receipt of a signal representative of termination of an exposure. The camera also includes a selector capable of being set at a single frame photographing position as well as at a continuous photographing position, and a control mechanism for preventing generation of the signal with the selector set at the single frame photographing position. A signal generating device is associated with a film wind-up stop mechanism for generating the signal when the stop mechanism is disengaged from a film wind-up and shutter charge mechanism in response to termination of an exposure, disengagement of the stop mechanism being prevented or the signal generating device being deactivated by the control mechanism when the selector is set at its single frame photographing position. The control mechanism is disabled to permit the generation of the signal when a shutter release member is returned from its operative position to its non-operative position.
