Abstract
A film cassette for an automatic film processor is provided with a cam surface for consistently and accurately guiding a force-transmitting member into and out of engagement with a pocket formed in a sheet element of a self-developing, peel-apart film unit enclosed therein, for the subsequent movement of the sheet element into a developer liquid spread system located in the film processor for engagement with other film unit elements.
Claims9
A film cassette for photographic apparatus, of the type having a force-transmitting member for moving a photographic sheet element of a self-developing, peel-apart film unit into or out of the apparatus for subsequent sheet element processing, comprising a cassette for enclosing a plurality of photographic sheet elements, in a stacked relation, of the type wherein each such sheet element has a leading end with a pocket on one side thereof for engagement with the force-transmitting member, said cassette having a motion-guiding surface thereon for engaging a first portion of the force-transmitting member for the purpose of guiding a second portion of the force-transmitting member into the sheet element pocket, for movement therewith.
A film transport system for moving a sheet element of a self-developing, peel-apart photographic film unit into or out of photographic apparatus comprising:
- a peel-apart film-sheet element having a leading end and having a pocket located on one side of said leading end;
- a cassette for enclosing a plurality of peel-apart film-sheet elements arranged in a stacked relation, said cassette having a withdrawal opening therein for the sequential movement of each of said sheet elements therethrough and having a force-transmitting member, motion-guiding surface thereon;
- and
- a moveably mounted force-transmitting member having a first portion for engaging the sheet element pocket and having a second portion thereof for engaging said motion-guiding cassette surface and thereby guiding said first force-transmitting member portion into said sheet element pocket, for the subsequent movement of the sheet element through said cassette withdrawal opening.
