Automatic rewinding device for film in camera

摘要

When a detector detects that a motorized transport arrangement is winding film, or when a resetting arrangement detects that a full frame has been wound, a reset signal resets a timer. When the detector arrangement senses that the transport is not moving the film and the film has not been wound a full frame, a release signal actuates the timer which generates a switching signal. A switchover facility responds to the switching signal to cause the transport to stop winding and start rewinding.
