Abstract
Abstract Two transfer routes for exposed films are provided in a film processor, in one of the two ordinary films which require treatments of developing, stopping, fixing and washing with being transferred, and in the other route wash-off films which require only a treatment of the washing with being transferred. The ordinary films are transferred through the former route with being treated several processes, and the other hand, the wash-off films are directly transferred into a washing tray through the latter route, skipping over treatments of developing, stopping and fixing. The by-pass mechanism for wash-off films can be swinged around a shaft, by which the maintenance for the film processor becomes easier. Processing for different kinds of films can be performed, depending on the kind of films to be processed, with a film processor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
Apparatus for processing films comprising: a processing route having a plurality of different processing sections for processing an exposed ordinary film and means for transferring the exposed ordinary film continuously along the processing route from one processing section to the next; first film inlet means for communicating film inserted therein to said transferring means for transferring film along the entire processing route; second film inlet means; and by-pass transferring means for receiving film from said second inlet means and for delivering film to said transferring means for by-passing at least one processing section; wherein film requiring only a single-bath developing treatment and washing is transferred via said by-pass transferring means through only a portion of said processing route.
Claim 2
Dependent Claim
118 words

Claim 3
Dependent Claim
52 words
Apparatus according to claim 1, wherein said processing route includes at least one washing section, wherein said by-pass transferring means is arranged to deliver film directly to said washing section, and wherein said washing section, when used to process a film requiring only a single-bath developing treatment, is supplied with activating fluid.
Claim 4
Dependent Claim
46 words
Apparatus according to claim 2, wherein the by-pass transferring means is movable from a first position, for delivering film from said second inlet means to said transferring means, to a second position to prevent interference with the processing route when an ordinary film is being processed.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 3, wherein said by-pass transferring means is mounted on a mounting member having one end rotatably supported by the apparatus for moving said by-pass transferring means between said first and second positions.
Claim 6
Dependent Claim
39 words
Apparatus according to claims 1, 2, 3, or 4, wherein said first and second film inlet means are formed by a bifurcated insertion member for selectively delivering film to one of said transferring means and said by-pass transferring means.
Claim 7
Dependent Claim
26 words
Apparatus according to claim 5, wherein said first and second film inlet means include a switching member operable to close either one of the film inlets.
