ABSTRACT:
A microimage recording apparatus of the type utilizing an elongated master film strip movable along a master film processing path and a duplicate film strip movable along a duplicate film strip processing path for making duplicates of successive developed image areas on the master film strip includes a duplication station having a support for the master film strip to position a developed image area thereon in a duplication position along the master film strip path. Support is provided for the duplicate film strip along a segment of the duplicate film processing path merging with the master film strip path at the duplication station. The master and duplicate film strips are biased together in close contact at the duplication station against a glass platen and light is passed through a developed image area on the master film strip to create a latent, duplicate image area on the duplicate film strip for subsequent development. A master film transport system is provided for moving successive developed image areas into and out of the duplication position along the segment of merged film paths and a separately controlled duplicate film transport apparatus is provided for positioning and moving the duplicate film into and out of the duplication position for exposing the duplicate film through a selected developed image area on the master film strip to make one or more duplicates thereof.
