ABSTRACT:
A microfiche camera suitable for use in a low cost microfiche system for exposing a plurality of image frame areas on a single card-like film unit. The camera includes a carriage mounted lens that is moved incrementally through linear passes to expose sequential image frame areas disposed in a laterally extending row on the film unit. A shutter that defines an elongated shutter aperture extending along the length of the row cooperates with a light shield, that moves incrementally with the carriage to maintain a shield aperture in operative relation with the lens, for controlling the transmission of scene light to the film unit such that it passes through the lens at each of its sequential imaging positions to expose a corresponding one of the image frame areas, but is blocked from transmission to the other image frame areas in the row during an exposure interval.
