Abstract
A film drive device for a camera in which the film is transported by an electric motor as the drive source, comprises detecting means for detecting that the winding of all the frames of the film is complete, manually operable switching means for forcibly changing over the film to a rewind state, and operation control means for shifting from a film windup state to the film rewind state. The operation control means makes a first operation of shifting to the film rewind state in response to the completion of the winding by the detecting means and a second operation of shifting to the film rewind state by the operation of the switching means different from each other. Therefore, an efficient shifting to the rewind state can be performed.
