Abstract
Abstract A photographic printing or developing machine has a station for processing bands of photographic material. The processing station has an inlet side and an outlet side. A first station provided with several receiving areas for wheeled take-off cassettes carrying coild bands of photographic material is located adjacent to the inlet side. A second station provided with several receiving areas for wheeled, empty take-up cassettes is disposed adjacent to the outlet side. The first and second stations each have a mechanism for conveying and guiding bands of photographic material between the processing station and the various receiving areas. Furthermore, a detecting mechanism is located at each receiving area and the detecting mechanism, as well as the conveying and guiding mechanism, are connected to an electronic control unit. In operation, a loaded take-off cassette is positioned at each receiving area of the first station and an empty take-up cassette is positioned at each receiving area of the second station.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
135 words
An apparatus for processing photosensitive material, comprising a processing station for such material; at least one station to one side of said processing station designed to accommodate a plurality of carriage-like cassettes for photosensitive material at respective locations of said one station; means for conveying and guiding photosensitive material between said processing station and each of said locations; detecting means for sensing the presence and absence of photosensitive material in the region of each of said locations; and control means operable to activate said conveying and guiding means in response to signals from said detecting means, said control means causing said conveying and guiding means to transport photosensitive material between said processing station and a preselected one of said locations when said detecting means issues a predetermined signal from the region of said preselected location.
Claim 2
Independent Claim
135 words
An apparatus for processing photosensitive material, comprising a processing station for such material; at least one station to one side of said processing station designed to accommodate a plurality of carriage-like cassettes for photosensitive material at respective locations of said one station; means for conveying and guiding photosensitive material between said processing station and each of said locations; detecting means for sensing the presence and absence of photosensitive material in the region of each of said locations; and control means operable to activate said conveying and guiding means in response to signals from said detecting means, said control means causing said conveying and guiding means to transport photosensitive material between said processing station and a preselected one of said locations when said detecting means issues a predetermined signal from the region of said preselected location.
Claim 3
Dependent Claim
159 words
The apparatus of claim 1, further comprising an additional station to another side of said processing station designed to accommodate a plurality of carriage-like cassettes for photosensitive material at respective additional locations of said additional station; additional detecting means for sensing the presence and absence of photosensitive material in the region of each of said additional locations; and additional means for conveying and guiding photosensitive material between said processing station and each of said additional locations, said control means causing said additional conveying and guiding means to transport photosensitive material between said processing station and a preselected one of said additional locations when said additional detecting means issues a predetermined signal from the region of said preselected additional location, and said conveying and guiding means being designed to withdraw photosensitive material from a cassette at said one station, convey the material into and out of said processing station and introduce the material into a cassette at said additional station.
