Abstract

An instant film pack for use with an instant camera has a case, with a back wall and a front wall in which an exposure aperture is formed. 10 rectangular film units are stacked and contained in the case. The film units after exposure are exited through an outlet slot. Two access openings are formed in the back wall of the case, and receive entry of pads of the camera. A light-shielding sheet is contained between the back wall and the film units, closes the access openings openably, and prevents ambient light from entry through the access openings. The light-shielding sheet, pressed by the pads, presses the film units toward the exposure aperture. Two pressing curved ridges are projected from the back wall in an arcuate shape, and contact at least two lateral edges which are formed beside the light-shielding sheet, and directed toward the outlet slot. The pressing curved ridges prevent the film units from being depressed to a rear of the exposure aperture inside the case.
