ABSTRACT:
A photographic copying apparatus for the processing of lengths of copy masters adhesively bonded into long strips, in particular negative film strips that may be wound onto film spools, comprises an exposure station located along a transport path of the negative film strip, wherein the negative film strip is exposed master by master onto an unexposed photographic copy material, in particular unexposed photographic paper, passed along a paper path extending within the copy apparatus, preferably under the film transport path, through the exposure station. The copy apparatus is equipped with two supply spools located on the inlet side of the photographic copy apparatus from which the negative film strip may be wound off selectively, and with two winding spools located on the outlet side of the copy apparatus onto which the negative film strip may be selectively wound after each passage through the copy apparatus. One supply spool and one winding spool are always connected with the negative film strip being processed, while the others are in waiting positions. The configuration according to the invention of the photographic copy apparatus consists in particular of the storage and winding spool connected with the film strip being located in an approximate straight line extension of the film transport path and directly adjacent to it, while film spools in waiting positions are located in an approximate straight line extension of the film transport path behind the film spools in the working positions.
