Instant film pack and device using the same

An instant film pack comprising:

• a plurality of instant film units each having a developer pod which contains a developer;
• a film cover having stiffness higher than that of the instant film unit;
• and
• a case that accommodates the plurality of instant film units and the film cover laminated on top of each other, and includes a discharge port from which the instant film unit or the film cover is discharged,
• wherein the film cover includes:
• a cover member that is overlapped in front of the instant film unit positioned in the foremost layer,
• accompanying prevention ribs that are arranged in parallel with a discharge direction in a case where the film cover is discharged from the discharge port and prevent the instant film unit positioned in the next layer from being discharged together with the film cover in a case where the film cover is discharged through the discharge port,
• a pair of first light shielding ribs that is arranged in parallel with each other in a width direction perpendicular to the discharge direction, and
• bending guide grooves each of which is formed on an outside of each of the accompanying prevention ribs in the width direction and along each of the accompanying prevention ribs, so that a portion at the distal end of the film cover and outside the accompanying prevention ribs can tilt in a protruding direction of the accompanying prevention ribs,
• wherein
• the accompanying prevention ribs and the first light shielding ribs are formed on a front surface of the cover member, and
• the accompanying prevention ribs tilt so as to gradually increase from a distal end of the film cover in the discharge direction toward a proximal end.
