ABSTRACT:
The apparatus comprises a device for forming a latent image on a negative film according to data stored on a base medium; a first pair of transport rollers for pinching and carrying simultaneously the negative film and a receiving strip into a superimposition zone, the exposed film being developed into a treatment bath along said superimposition zone and a positive image being transferred by diffusion onto the receiving strip from the negative film; a second pair of transport rollers placed at the outlet of the superimposition zone, for pinching and carrying the receiving strip only; and registering means for sensing the advancing movement of the receiving strip and for controlling intermittently, at time intervals determined by the detection of guidemarks formed on the receiving strip, the production on the negative film of an image comprising a set of data stored discontinuously on the base medium.
