Abstract
Abstract A device for automatic producing copies in accordance with a diffusion process from a two-sheet material includes a copy-receiving arrangement receiving exposed copies from a diffusion-developing device and having a plurality of flat copy-receiving surfaces positioned in a diffusion space for a full development of the copies being processed. Each copy is located on the respective copy-receiving surface so that no mutual displacement between the positive sheet and negative sheet of each copy takes place. Each copy is transported from the position at the entrance of the diffusion space to the position at the exit of the diffusion space in a step-like fashion. The ends of the copy-receiving surfaces are connected to a rotational transport device one after another in the endless belt-manner.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A device for exposing and developing light-sensitive material, comprising a housing; a film-exposing means and developing means for processing two-sheet material in accordance with a diffusion process to obtain a plurality of two-sheet copies, said film-exposing means and said developing means being positioned in said housing; a diffusion space formed in said housing for a full development of copies and having an entrance and an exit; copy-receiving means including at least one flat copy-receiving wall having a format corresponding to that of a copy being processed and receiving each copy from said developing means so that two sheets in each copy lie on said wall in contact with each other; and means for shifting said wall in a step-like manner from a filling position at the entrance of said diffusion space to a discharge position at the exit of said diffusion space.
Claim 2
Independent Claim
142 words
A device for exposing and developing light-sensitive material, comprising a housing; a film-exposing means and developing means for processing two-sheet material in accordance with a diffusion process to obtain a plurality of two-sheet copies, said film-exposing means and said developing means being positioned in said housing; a diffusion space formed in said housing for a full development of copies and having an entrance and an exit; copy-receiving means including at least one flat copy-receiving wall having a format corresponding to that of a copy being processed and receiving each copy from said developing means so that two sheets in each copy lie on said wall in contact with each other; and means for shifting said wall in a step-like manner from a filling position at the entrance of said diffusion space to a discharge position at the exit of said diffusion space.
Claim 3
Dependent Claim
18 words
The device as defined in claim 1, wherein said copy-receiving means include a plurality of flat copy-receiving walls.
Claim 4
Dependent Claim
38 words
