PURPOSE:To prevent unnecessary power consumption and enable a photographer to know the end of a film accurately by interrupting the electricity conduction to a motor by a detecting laver which is displaced by the torque owing to the rotation stop of a spool and displaying the end of the film. CONSTITUTION:A clutch plate 26 is provided coaxially to driving gears 22, 25, and a clutch lever 35 is engaged. The lever 35 is pivotally supported 32a at one end of a film end detecting lever 32. The lever 32 is energized counterclockwise with the force smaller than the torque at the film end by a spring 33. For this purpose, the detaining force of the spring 33 acts upon the plate 26 through the lever 35. If with this constitution the high torque at the film end is applied, the lever 32 turns clockwise against the above-described detaining force and a holding lever 37 also rotates in the same direction, thereby a switch S2 for electricity conduction to a motor M is turned off. The end of the film is displayed by a member 37c for display. Thereby, the generation of the overcurrent of the motor caused at the winding end of the film is prevented and the photographer can accurately confirm the end of the film. |
