Abstract

Abstract The invention provides an apparatus for processing a sheet-shaped halide photographic light-sensitive material having a hydrophilic colloidal layer on a substrate. In the apparatus, there are provided a plurality of guides for guiding the sheet-shaped material. Each of the plurality of guides has a slit for passing the sheet-shaped material through it, and the slit of the guide body is shaped to temporarily hold the developing solution by the work of surface tension of the solution. A heating device for heating the developing solution temporarily held by the slit is further provided. The sheet-shaped material is processed while passing through the slit during the temporary holding of the heated developing solution.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 139 words
An apparatus for processing a sheet-shaped silver halide photographic light sensitive material comprising: a plurality of guide means for guiding the sheet-shaped material, each of the plurality of guide means including a guide body having a slit for passing the guided sheet-shaped material therethrough; feed means for feeding developing solution to the plurality of guide means; the plurality of guide means being arranged vertically spaced apart to allow the developing solution fed by the feed means to drain downward from a slit of an upper guide body to a slit of a lower guide body; and each guide body of the plurality of guide means being shaped so that its slit temporarily holds the developing solution therein and that the sheet-shaped material is processed while passing through the slit of each guide body by the temporarily held developing solution.
Claim 2
Independent Claim 139 words
An apparatus for processing a sheet-shaped silver halide photographic light sensitive material comprising: a plurality of guide means for guiding the sheet-shaped material, each of the plurality of guide means including a guide body having a slit for passing the guided sheet-shaped material therethrough; feed means for feeding developing solution to the plurality of guide means; the plurality of guide means being arranged vertically spaced apart to allow the developing solution fed by the feed means to drain downward from a slit of an upper guide body to a slit of a lower guide body; and each guide body of the plurality of guide means being shaped so that its slit temporarily holds the developing solution therein and that the sheet-shaped material is processed while passing through the slit of each guide body by the temporarily held developing solution.
Claim 3
Dependent Claim 27 words
The apparatus of claim 1, further comprising means for cleaning the slit of each guide body by supplying washing water to the slit of each guide body.
Claim 4
Dependent Claim 29 words
