INSTANT FILM PACK
Document Type and Number:
Japanese Patent JP2000081689
Kind Code:
A
Abstract:
To prevent the faulty ejection of an instant film unit.
A push-up rib 30 is formed on a film cover 5 with which the exposure aperture of a case 3 is covered, and a push-up projection 43 abutting on the rib 30 is formed on the internal wall surface of the case 3. Thus, the film cover 5 is pushed up to the side of the film unit 4 so as to prevent the film unit 4 from facing to an ejection port 7 at the time of ejecting the cover 5, whereby the film cover 5 and the film unit 4 are prevented from being ejected together. There, projections for displacement 44 are formed at both ends of the port 7, and both ends of the film unit 4 are deformed to uniform shape by the projections 44, so that the faulty ejection is prevented.
