ABSTRACT:
A photographic apparatus, suitable for use in a low cost microfiche system, for exposing a plurality of image areas on a single card-like film unit, preferably of the self-developing type. The apparatus has a fixed object plane, where documents to be copied are supported; a fixed film plane spaced from the object plane; a laterally extending row of gate apertures for defining a row of image areas on a film unit at the film plane and a system for advancing a lens laterally over the gate areas in increments which locate the lens at successive imaging positions in imaging relation with a corresponding one of the image areas. At those imaging positions that correspond to an image area which is laterally offset with respect to the object plane center the lens is proportionally offset with respect to the image area center so that an image formed by the lens of an object centered at the object plane is centered with respect to the image areas. At each of the imaging positions proper registration of the image is achieved by locating the rear nodal point of the lens on a direct line extending between the object plane center and the center of a corresponding one of the image areas.
