ABSTRACT:
Apparatus for producing microform records from computer stored data or other electrical data signal sources forms on the screen of a cathode ray tube at rapidly occuring intervals successive hard copy-appearing images of such data which is reduced in size by a bundle of tapered fiber optic filaments with a wide light receiving end encompassing the screen of the cathode ray tube and a narrow light projecting end encompassing an area of the frame of a microfiche card. The successively produced images at the narrow end of the fiber optic filament bundle are applied to successive frames of a heat developable masking film strip requiring more time to develop than the imaging intervals and moved in step-by-step fashion past the narrow end of the fiber optic bundle, a heating bar and an image transfer station where a flash of light is passed through the masking film strip to transfer a negative image thereon to a frame of an archival add-on microfiche card-forming film. The transfer of a cathode ray tube image to the masking film, the application of a heating bar to a previously imaged frame of the masking strip and the transfer of a previously imaged portion of the masking film may take place simultaneously. The heating bar has a length several frame lengths long so that a frame of the masking film is completely developed over several imaging intervals.
