Patent attributes
The film cover constituting the instant film pack includes a cover member, a pair of accompanying prevention ribs, a pair of outer light shielding ribs, and a pair of inner light shielding ribs. The accompanying prevention ribs are arranged in parallel with a discharge direction from a distal end of the film cover in the discharge direction. Similarly to the accompanying prevention ribs, since the outer light shielding ribs are formed on a front surface of the cover member, the outer light shielding ribs together with the accompanying prevention ribs can prevent the film unit from accompanying. A tilt surface of which a protruding height gradually decreases toward a distal end from a proximal end of the cover member is formed on the accompanying prevention rib.
