Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
An automatic processor operable for simultaneous processing first and second different kinds of light-sensitive silver halide photographic material comprising a common processing tank for commonly processing said light-sensitive material first and second different kinds of processing tanks for processing respectively the first and second different kinds of light-sensitive silver halide photographic materials; and first and second conveying means operable for conveying said first and second different light-sensitive materials said first and second different kinds of processing tanks at the same time, while excluding said first light-sensitive material from said second tank and said second material from said first tank.
Claim 2
Dependent Claim
99 words
An automatic processor operable for simultaneous processing first and second different kinds of light-sensitive silver halide photographic material comprising a common processing tank for commonly processing said light-sensitive material first and second different kinds of processing tanks for processing respectively the first and second different kinds of light-sensitive silver halide photographic materials; and first and second conveying means operable for conveying said first and second different light-sensitive materials said first and second different kinds of processing tanks at the same time, while excluding said first light-sensitive material from said second tank and said second material from said first tank.
Claim 3
Dependent Claim
25 words
The automatic processor according to claim 1, wherein the first and second processing tanks and the common processing tank are provided in an integral combination.
Claim 4
Dependent Claim
44 words
The automatic processor according to claim 1, further comprising a second common processing tank wherein the first and second processing tanks are color developing processing tanks, the common processing tank is a bleach-fixing tank and the second common processing tank is a stabilizing tank.
Claim 5
Dependent Claim
16 words
The automatic processor according to claim 1, wherein said processing tanks employ substantially no washing water.
Claim 6
Dependent Claim
25 words
The automatic processor according to claim 1, wherein the first conveying means is an endless belt and the second conveying means is an endless belt.
Claim 7
Dependent Claim
158 words
A process for automatically processing different kinds of photographic material including at least a first and a second kind of light-sensitive silver halide photographic materials, in an automatic processor having at least one kind of different processing tanks, one kind of shared processing tanks, and at least two conveying means each operable to convey either said first or said second kind of light sensitive photographic materials; said process comprising: conveying said first kind of photographic materials through processing tanks containing first processing solutions for processing said first kind of photographic materials and simultaneously; conveying said second kind of photographic materials through processing tanks containing second processing solutions for said second kind of photographic materials; at least one of said first and said second processing solutions being the same solution and being in said shared processing tanks; and at least one of said first and said second processing solutions being different and being contained in said different processing tanks.
Claim 8
Dependent Claim
158 words
A process for automatically processing different kinds of photographic material including at least a first and a second kind of light-sensitive silver halide photographic materials, in an automatic processor having at least one kind of different processing tanks, one kind of shared processing tanks, and at least two conveying means each operable to convey either said first or said second kind of light sensitive photographic materials; said process comprising: conveying said first kind of photographic materials through processing tanks containing first processing solutions for processing said first kind of photographic materials and simultaneously; conveying said second kind of photographic materials through processing tanks containing second processing solutions for said second kind of photographic materials; at least one of said first and said second processing solutions being the same solution and being in said shared processing tanks; and at least one of said first and said second processing solutions being different and being contained in said different processing tanks.
Claim 9
Dependent Claim
37 words
The process of claim 6, wherein at least one of said processing solutions is a bleach-fixing solution containing a ferric complex of an organic acid having a molecular weight of the organic acid of at least 300.
Claim 10
Dependent Claim
15 words
The process according to claim 7, wherein said ferric complex is iron (III) sodium ethylenediaminetetraacetate.
