Claims

[Claims for Utility Model Registration] In a motor-driven camera that winds and rewinds film by rotating a motor, there is a first device that detects the end of film rewinding and stops the film rewinding operation.
and a second switch that is closed by the opening operation of the back cover of the camera, and when the back cover of the camera D is open,
A film rewinding device characterized in that the second switch enables rewinding of the film L regardless of the operating state of the first switch.
