ABSTRACT:
A sheet film pack has a pack housing containing a plurality of sheet film units in a stack therein, a lid slidable relative to the pack housing to open or close an open top of the pack housing, and a plate spring mounted on an inner bottom surface of the pack housing to urge the stack of sheet film units toward the open top. Each sheet film unit consists of a sheet of photographic film and a plastic film sheath backing and fringing the sheet film. The plate spring has a pair of arched arms which extend parallel to each other along side zones of a bottom one of the sheet film units, such that peak areas of the arms contact the bottom sheet film unit at positions within 15 mm from side edges of the sheet film unit.
