PURPOSE:To prevent a film end from being detected erroneously, and to reduce power consumption, by providing a latency time switching means, and varying the latency time length of said means. CONSTITUTION:When there is a great difference in the time from the starting of film feeding to the ending of winding owing to a difference in the kind of a film, for example, when the drawing-out torque of a film is large, the time from the starting of film feeding to the generation of a winding completion signal is set long with a changeover switch 6 to lower the possibility that a part other than a film end is recognized as the film end erroneously. When the drawing-out torque of a film is small, the latency time is set short to reduce the power consumption even if the film is tensed at its film end. |
