A modular microfiche duplicator including a basic processing module which co-operates with a selected one of a plurality of different film advancing modules. In the basic processing module, the unexposed film is taken from a supply reel in a continuous strip and is drawn through an exposure station in metered segments. The microfiche sheet which is to be duplicated is inserted into the exposure station and an inflated air bag platen presses the films together as they are exposed to radiation from a columnar light source. The exposed segment of the film is then drawn into a film advancing module as the strip of film is advanced to the next segment.
