Abstract
A film transporting system for a photographic camera is adapted to advance a film roll loaded in the camera by one frame upon replacement of a source battery. A film transporter including an electric motor, or the like, is actuated to selectively perform film advance or film rewinding. A film travel detector detects that the film roll has been advanced by a predetermined amount and applies a signal to the film transporter. Operation of the film transporter is stopped by this signal. Upon replacement of the source battery, the film transporter advances the film roll by one frame, and thereupon the film transporter is stopped under control of the film travel detector. Accordingly, upon replacement of the source battery, the film roll is advanced by one frame in readiness for a next photograph.
