Photographic image precision reproportioning system

摘要

A photographic reproportioning apparatus for changing one dimension or edge configuration of a two dimension image contact print exposed on a photosensitive film moved by a support platen in a predetermined linear direction with respect to the image being reproduced by a reversible synchronous motor. A stationary overlying film carriage supports the original film image in contact with the photosensitive film. An opaque mask overlies the film support members and includes a motor moving an aperture bar assembly in a selected direction relative to the sensitive film. A light passing slit, in the aperture bar assembly, transversely of the direction of its movement, exposes the film from an overhead light source during movement of the mask.
