ABSTRACT:
An apparatus for forming enlarged exposures of film negatives is provided. The apparatus is adapted to be coupled to the housing of a conventional photo-processing machine without requiring permanent modification of the conventional machine. The apparatus includes a pair of magazines, one magazine of which houses a roll of unexposed paper. The unexposed paper is fed from the one magazine, vertically through the apparatus and into the other magazine. A mirror placed in the conventional machine, reflects a focussed light beam that has passed through a negative. The light beam is directed into the apparatus so that it impinges on a portion of the unexposed paper passing therethrough thereby forming an exposure of the negative on the paper. Drive motors automatically advance the paper from the one magazine to the other, upon exposure of the negative on the paper. A cutter is provided for cutting the paper when a complete reel of negatives has been exposed.
