Abstract
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.
