ABSTRACT:
Disclosed are a technique that in the film feeding control of a camera, before the film is wound up, when the voltage of a battery circuit for supplying voltage to the camera is above a voltage level high enough to wind-up the film, a film winding operation is initiated, and, if this winding-up operation does not terminate normally, that the film has ended is determined and the film is rewound, and another technique that when the above-described voltage level is detected, a motor for the rewinding is used as the load of detecting the voltage level of the above-described battery circuit.
