Apparatus for packaging and for using self-developing photographic film

摘要

A photographic film cassette having a stack of self-contained, self-developing film units includes leaders interconnecting the units to enable them to be withdrawn from the cassette one at a time. A Z-fold or zig-zag configuration of the film units and leaders is employed, with a leader interconnecting the leading edge of one film unit and the trailing edge of the preceding film unit. The cassette structure cooperates with the connection of the leader to the film unit leading edge to project a film unit against a cassette wall to prevent inadvertent withdrawal of the unit. Staggered loading, and alternatively symmetrical back-to-back loading of the film units in the cassette, can increase the number of film units the cassette accommodates in a limited space.
