ABSTRACT:
In the disclosed film rewind device a detecting switch detects the movement of film which is taken up on a spool during the process of electrically rewinding the film into a cartridge and a timer automatically brings the film rewinding operation to a stop a predetermined period of time after a detecting switch ceases detecting the film movement. The period of time set at the timer is shortened in response to even a slight degree of film movement after the predetermined period of time.
