INSTANT FILM PACK AND DEVICE USING THE SAME
First Claim
1. An instant film pack comprising:
- a plurality of film units each having a developer pod which contains a developer;
a case having an exposure opening and a slit-shaped discharge port, and laminating and accommodating the plurality of film units;
a film cover covering an exposure surface of the film unit to lighttightly block the exposure opening and being ejected from the discharge port;
an accompanying prevention rib formed at a distal end portion on a front surface of the film cover facing the exposure opening so as to protrude from both side edge portions with a height equal to a gap of the discharge port, and preventing the film unit positioned in the topmost layer from being ejected; and
a bending guide portion tilting an outer portion of the accompanying prevention rib of the film cover in a protruding direction of the accompanying prevention rib.

Abstract
A film cover covers an exposure surface of a film unit to lighttightly block an exposure opening and is ejected from a discharge port. A bending guide groove is formed on the outside of an accompanying prevention rib in a width direction of a cover member along the accompanying prevention rib. The bending guide groove tilts a side edge portion, which is a distal end portion of the film cover, and the portion outside the accompanying prevention rib, in a protruding direction of the accompanying prevention rib. Since the side edge portion is bent by the bending guide groove, the both side edges portions do not engage with the discharge port, and the film cover can be ejected smoothly from the discharge port.
