发明名称 SIMPLE LOADER FOR FILM
摘要 PURPOSE:To make loading of a film easy and sure by so arranging a titled device that the opening of an outside cylinder disposed on the outer side of a spool always faces the prescribed direction at the time of starting winding the unexposed film by inserting the same into said opening. CONSTITUTION:The user opens a rear cover 27, and inserts a film F through the opening 15 in the body part 12a of an outside cylinder into between a spool 5 and the part 12a. At this time, one end edge 12e of the part 12a is contained in the notched part 8a of a lever 8 so that no level differences are produced. If the user winds the film after this, the sprocket 4 rotates counterclockwise and the spool 5 clockwise, but the outside cylinder 12 of the spool does not rotate if the film F is inserted just slightly. When the spool 5 is rotated, the film F is fed by the sprocket 4 in accordance with the meshing of perforations and pawls 4a, 5a, and is thereby wound successively on the spool 5.
