ABSTRACT:
A step and repeat camera is disclosed which includes a module for supporting a supply of film material, for metering a length of film material from the support and cutting the film to a predetermined length, a second module for supporting the cut sheet of film with the light sensitive coated surface positioned downward and moving the film along X and Y coordinates to position successive areas of the film over an image projecting lens. The support moves the film from a first film receiving conveyor to a titling area where a title is contact exposed onto the film, through the imaging section along the coordinates, and to the discharge conveyor. The third module includes apparatus for conveying the film over a DC corona bar which causes the film to adhere to a hot processing drum and to be carried thereby under a heated shoe past an AC corona bar to discharge the film, permitting the same to drop from the surface of the drum across its initial infeed path into a cooling chute.
