Abstract
Abstract In a system comprising a first processing route for a first color photosensitive material, typically negative film including a developing tank, a blix tank, and a washing tank, and a second processing route for a second color photosensitive material, typically color paper including a developing tank, a blix tank, and a washing tank, the first and second processing routes are arranged in juxtaposition. Their corresponding tanks are channeled such that (1) the blix solution from the blix tank of the second route is passed to the blix tank of the first route, (2) the color developer from the developing tank of the first route is passed to the developing tank of the second route, and (3) the wash water from the washing tank of the first route is passed to the washing tank of the second route. A used processing solution overflowing from one route is reused in a corresponding tank of the other route.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
In a system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank and a processing tank having a fixing function, the improvement comprising: a first processing route for a first color photosensitive material including a first developing tank containing color developing solution and a first processing tank containing processing solution having a fixing function, and a second processing route for a second color photosensitive material including a second developing tank containing color developing solution and a second processing tank containing processing solution having a fixing function, said first and second processing routes being arranged in juxtaposition, and transfer means for passing said processing solution from said second processing tank to said first processing tank.
Claim 2
Dependent Claim
128 words
In a system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank and a processing tank having a fixing function, the improvement comprising: a first processing route for a first color photosensitive material including a first developing tank containing color developing solution and a first processing tank containing processing solution having a fixing function, and a second processing route for a second color photosensitive material including a second developing tank containing color developing solution and a second processing tank containing processing solution having a fixing function, said first and second processing routes being arranged in juxtaposition, and transfer means for passing said processing solution from said second processing tank to said first processing tank.
Claim 3
Dependent Claim
61 words
The photosensitive material processing system of claim 1, wherein said first color photosensitive material has at least one silver iodobromide emulsion layer and said second photosensitive material has at least one silver chlorobromide or silver chloride emulsion layer, and the system further includes a transfer means for passing color developing solution from said first developing tank to said second developing tank.
Claim 4
Dependent Claim
105 words
In a system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank, a processing tank having a fixing function, and a water washing tank, the improvement comprising: a first processing route for a first color photosensitive material including a first washing tank containing wash liquid, and a second processing route for a second color photosensitive material including a second washing tank containing wash liquid, said first and second processing routes being arranged in juxtaposition, and transfer means for passing wash liquid from said first washing tank to said second processing tank.
Claim 5
Dependent Claim
105 words
In a system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank, a processing tank having a fixing function, and a water washing tank, the improvement comprising: a first processing route for a first color photosensitive material including a first washing tank containing wash liquid, and a second processing route for a second color photosensitive material including a second washing tank containing wash liquid, said first and second processing routes being arranged in juxtaposition, and transfer means for passing wash liquid from said first washing tank to said second processing tank.
Claim 6
Dependent Claim
85 words
The photosensitive material processing system of claim 3, wherein said first processing route further comprises a first developing tank containing color developing solution and a first processing tank containing processing solution having a fixing function, and said second processing route further comprises a second developing tank containing color developing solution and a second processing tank containing processing solution having a fixing function, and the system further comprises a second transfer means for passing processing solution from said second processing tank to said first processing tank.
Claim 7
Dependent Claim
61 words
The photosensitive material processing system of claim 4, wherein said first color photosensitive material has at least one silver iodobromide emulsion layer and said second photosensitive material has at least one silver chlorobromide or silver chloride emulsion layer, and the system further comprises a transfer means for passing color developing solution from said first developing tank to said second developing tank.
Claim 8
Independent Claim
135 words
A system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank, a processing tank having a fixing function, and a water washing tank, the improvement comprising: a first processing route for a first color photosensitive material including at least a first fore stage washing tank containing wash liquid and a first aft stage washing tank containing wash liquid; a second processing route for a second color photosensitive material including at least a second fore stage washing tank containing wash liquid and a second aft stage washing tank containing wash liquid, said first and second processing routes being arranged in juxtaposition; and transfer means for passing wash liquid from said first fore stage washing tank to said second fore stage washing tank.
Claim 9
Independent Claim
135 words
A system for wet processing an exposed silver halide color photosensitive material by carrying the photosensitive material along a processing route including a developing tank, a processing tank having a fixing function, and a water washing tank, the improvement comprising: a first processing route for a first color photosensitive material including at least a first fore stage washing tank containing wash liquid and a first aft stage washing tank containing wash liquid; a second processing route for a second color photosensitive material including at least a second fore stage washing tank containing wash liquid and a second aft stage washing tank containing wash liquid, said first and second processing routes being arranged in juxtaposition; and transfer means for passing wash liquid from said first fore stage washing tank to said second fore stage washing tank.
