Apparatus for processing photographic sheet material including at least two rollers which are rotatively supported on corresponding shafts and biased together by springs acting on one of the shafts is provided with a mechanism operable to separate the rollers. The mechanism consists of a cam carried in normally free-wheeling relation on at least one end of one of the shafts, a cooperating cam follower carried on at least one end of the other shaft and a clutch that can be actuated to engage each such cam on its shaft for temporary rotation therewith to thereby displace the cam into contact with a cam follower and bring about separation of the roller shafts and the rollers supported thereon. The ends of the shaft acted on by the springs is preferably journaled in bearing blocks arranged in a frame for sliding movement towards and away from the other shaft and biased by the springs toward the other shaft. Preferably, the clutch is a one-way clutch that permits free rotation of the cam when the one shaft is rotating in one direction and engages to rotate the cam with the shaft when the shaft is caused to rotate in the other direction. Each cam is held in a given position relative to the frame when free-wheeling on its shaft by a detent abutting against a part of the frame.

Photographic processing apparatus

Photographic image-forming apparatus with replaceable cassette which comprises an exposure station for the imagewise exposure of a photographic silver halide emulsion layer element, a developing station wherein a silver halide developer liquid is applied to said imagewise exposed element, and a fixing station wherein a silver halide fixing agent is applied to the imagewise exposed element, and driving means for transporting the element through the stations, wherein at least the developing station (36) is incorporated into a processing cassette (35, 91) that contains developing liquid and removably fits into said apparatus, said cassette houses absorption means (40) effective for absorbing unused developer liquid brought into contact therewith, and the apparatus comprises means (78, 79, 80) operable in association with the processing cassette for bringing unused developer liquid in the cassette into contact with said absorption means when the cassette is removed from the apparatus.

Photographic processing application with replaceable cassette

A photographic processing cassette (35) for the processing of an exposed photographic silver halide emulsion layer element, which comprises:

Photographic processing cassette

A processing apparatus with several liquid stations for the wet processing of image-wise exposed photographic elements, e.g. sheets, wherein the different processing liquids are provided in different liquid compartments (85, 86, 87) of the processing cassette (72), that has openings (88,89,90,91) that are sealed by membranes (92), and wherein the rinsing water compartment is provided with perforate partitions (94) with a scavenging agent for removal of fixing agent ions and complexed silver ions from the rinsing water in said compartment.
