ABSTRACT:
The present invention relates to a photographic camera device in which current is supplied to the winding up motor device for automatically advancing the film and cocking the shutter and to a rechargeable electronic flash light device from a single common power source battery. The camera is provided with a voltage detecting device for detecting the voltage of the power source battery, and a control device for simultaneously supplying current to the winding up motor device and the flash light device when the power source voltage detected by the voltage detecting device is higher than a certain determined voltage, and for preventing current flow to the flash light device while the current is being supplied to the winding up motor device when the detected power source voltage is lower than the determined voltage. A further device prevents the operation of the trigger button when the power source voltage is not sufficient for operating the winding up motor device in the normal way, and also prevents the winding up motor device as well as the flash light device from being substantially operated.
