ABSTRACT:
A combined microfiche camera and projection apparatus. The apparatus includes an objective lens for forming a real image on the input end of a coherent bundle of light fibers (internally reflecting glass fibers). The output end of the bundle is dispersed into a plurality of spaced-apart coherent fiber sub-bundles. The ends of the latter terminate contiguous to the emulsion of a microfiche. A projection screen is spaced from the microfiche. The device functions both to record and to read out.
