A processor for multi-purpose film cassettes of the type containing photographic film during exposure, processing and projection, the processor having a nozzle plate slideable from an initial processing position in which a nozzle opening therein is aligned with a discharge opening in an initially sealed processing fluid reservoir to a projection position in which the nozzle plate seals the reservoir discharge opening. A pressure pad supported by spring means biases the film toward the nozzle plate during processing and is cooperable with the nozzle plate to effect a separation of the nozzle plate and pressure pad to allow unobstructed passage of the film strip during projection subsequent to processing. Means are provided for indicating electrically whether the film strip is processed or unprocessed, such means including either a conductive strip attachable to a pull strip for releasing the processing fluid or a pivotal arm blocked by such a pull strip to effect a change in circuit continuity between a pair of electric terminals on initiation of the processing cycle.
A photographic film cassette for use with other apparatus, said cassette configured for depositing a coating of processing fluid on a moving run of a cassette retained photographic film strip to develop images thereon, said cassette comprising:
An applicator for depositing a coating of processing fluid on a moving run of a photographic film strip, the applicator comprising:
A photographic film cassette for use with other apparatus for initially advancing a cassette retained film strip in a given forward direction while recording images thereon, then in a rewind direction opposite said forward direction while coating said film strip with processing fluid, and subsequently again in said forward direction, said cassette comprising:
A processor for a multi-purpose cassette containing a strip of photographic film during exposure, processing and projection, said processor being operative to deposit a uniform coating of processing fluid on a moving run of said film strip after exposure and comprising:
An applicator operative to deposit a coating of processing fluid on a moving run of a photographic film strip, the applicator comprising a chamber having an exterior surface including a chamber opening therein through which the processing fluid may pass to the film strip, a plate member having an opening therein, means for mounting said plate member between said chamber exterior surface and the moving run of film for movement of said plate member in a given direction from a first position, wherein said plate opening is in at least partial alignment with said chamber opening, to a second position, wherein said plate opening is out of alignment therewith, and means for sweeping the fluid from said plate opening as said plate member is displaced from its said first position to its said second position.
