ABSTRACT:
An opaque casing houses a plurality of instant photographic film units each of which has spaced apart photosensitive and cover sheets and an access hole for introduction of processing fluid into the volume between the sheets. The casing has a container of processing fluid. Fluid passage means from the container terminate at a small cross-sectional area opening positioned to align with the access holes of successively exposed film units so that processing fluid can be introduced into the film units.
