摘要： 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.

摘要： In an instant film pack of the type comprising a parallelepipedal housing having a top wall in which an exposure aperture is formed and a front end wall with a film unit exit slot through which an instant film unit is withdrawn, a supporting member is provided to prevent the film unit from being improperly withdrawn. The supporting member comprises a flexible resilient member attached to the bottom of the film pack at the front end and extending in the direction of withdrawal of the film unit. The flexible resilient supporting member is so disposed as to leave a distance of 0 to 6 mm between its front end and the slot defined between an edge controller and a front edge of a guide member of a pack holder in which the film pack is loaded for use.
