Abstract:
A self-developing film unit comprising:a) a first rectangular sheet having a plurality of exposure cut-outs at spaced-apart intervals, portions of the first rectangular sheet which separate individual exposure cutouts containing a frangible line running in a direction substantially perpendicular to the major axis of the first rectangular sheet; b) a second rectangular sheet having a plurality of exposure cut-outs at spaced-apart intervals, portions of the second rectangular sheet which separate individual exposure cutouts containing a frangible line running in a direction substantially perpendicular to the major axis of the second rectangular sheet; c) a plurality of positive receiving sheets; d) a plurality of negative or photosensitive sheets; e) an elastic carrier sheet; f) a plurality of photographic processing fluid supply pods; and g) a plurality of photographic processing fluid collection traps; the components being assembled such that the first and second rectangular sheets are aligned with exposure cut-outs and frangible lines in-register thereby forming a series of exposure frames separable along frangible lines, each of the plurality of in register exposure cut-outs, or exposure frames, having a leading edge and a trailing edge defined with respect to the order in which the edges pass a set of spread rollers in a camera in which the film unit is loaded, the leading edge of each exposure frame containing a channel in communication with a photographic processing fluid supply pod positioned between the first and second rectangular sheets, and the trailing edge of each exposure frame containing a channel in communication with a photographic processing fluid collection trap positioned between the first and second rectangular sheets, each exposure frame being backed on one side by a positive receiving sheet, and on the other side by a negative or photosensitive sheet, the elastic carrier sheet being adhered to each negative or photosensitive sheet, and to inter-exposure frame portions of the rectangular sheet to which the negative or photosensitive sheet is attached, frangible lines falling between each point of adherence to a negative or photosensitive sheet, and adjacent points of adherence to inter-exposure frame portions of the rectangular sheets.
