INSTANT FILM PACK AND DEVICES USING SAME

Title:

INSTANT FILM PACK AND DEVICES USING SAME

Document Type and Number:

WIPO Patent Application WO/2018/147069

Kind Code:

A1

Abstract:

The present invention provides an instant film pack and devices using the same such that failed ejection of a film cover is prevented. The film cover (30) covers the exposure surface of a film unit to block the exposure opening so as to be light-tight, and the film cover (30) is to be ejected from an outlet (31c). Bending inducing grooves (30g) are formed along entrainment prevention ribs (30b), outward of the entrainment prevention ribs (30b) in the width direction of the cover material (30a). The bending inducing grooves (30g) cause the side edge parts (30f) at the tip ends of the film cover (30) and outward of the entrainment prevention ribs (30b) to tilt in the projection direction of the entrainment prevention ribs (30b). Since the side edge parts (30f) bend due to the bending inducing groove (30g), both side edge parts (30f) no longer latch onto the outlet (31c), thereby allowing the film cover (30) to smoothly be ejected through the outlet (31c).
