Abstract
A film pack having a box-shaped case body containing instant picture film units therein includes a depressing unit for biasing the film unit toward an exposure opening of the film pack as well as local depressing members which urge peripheral portions of the film units toward the exposure opening. The biasing force of the local depressing members is substantially independent of the biasing force of the depressing unit, and the biasing force of the local depressing members varies with the number of film units remaining in the film pack, with the biasing force provided by the local depressing members being a maximum when the film pack is filled with film units.
