PROBLEM TO BE SOLVED: To provide a lightproof cover for an instant film pack which lessen discharge resistance and reduces the consumption of a battery for driving a discharge mechanism. SOLUTION: The lightproof cover 13 is for shading of the exposure opening of the film pack and is discharged to the outside of a camera form the discharge port of the film pack after loading into the camera. The top end of the lightproof cover 13 is provided with a freely elastic temple part 32 to be crushed by a developing roller and an auxiliary rib 45 erected around a rounded part projecting to the side reverse therefrom in order to prevent next layer film units from being carried out together at the time of this discharging. The successive intrusion of the film units of the next layers into the slit width of the discharge port 20 is prevented by their thicknesses.
