ABSTRACT:
In response to the film drive control pulse signal generated when the shutter is closed, a switching circuit is turned ON to energize a film driving motor. When the film has been transported by a predetermined length, another control signal is generated to turn OFF the switching circuit. A control circuit is connected to a control circuit for controlling the shutter and to a circuit for controlling the motor in such a way that in response to the multi-exposure mode signal the control circuit will not energize the motor even when the pulse signal has been generated after the exposure. Thus the camera control device offers versatile multi-exposure operation.
