Abstract
PURPOSE:To realize the assured winding of a film for the automatic film loading mechanism of a camera, by forwarding the film by a sprocket until the film is wound up to a spool. CONSTITUTION:The tip of a film is put on a patrone 13, and the camera back cover is closed. Thus the preliminary film winding mode is secured with a motor 1 turning toward an arrow mark. A clutch lever turns counterclockwise, and a gear 7 bites the gears 8 and 9. A sprocket 19 turns with its projected part 18a pressed by an end 17b of a spring 17a wound round a gear 17 to forward the film. The turning speed of the spool having a friction surface and a film pressing roller is set a little higher than that of the sprocket. Thus the film is driven by the spool after the film is wound up to the spool. The projected part may possibly hit the spring end 17b at the opposite side 18b but just ride over the end 17b since the side 18b formes a cam surface.
