Apparatus for producing microform records from multiple data sources

Abstract

Apparatus for producing microform records from hard copy or a cathode ray tube image or the like fed from a selected data source, includes an image-reducing projection system into which is selectively directed light reflected from hard copy or light from the face of a remote cathode ray tube to which white background CRT image-forming signals are fed. The reduced image involved is preferably applied first to a non-archival heat developable mask-forming film, like a dry silver film, and then the image on this film is transferred preferably to an archival film capable of later receiving additional data on unused portions thereof and most advantageously arranged as a microfiche card. A cathode ray tube smaller than the hard copy is positioned below but in spaced relation to a hard copy receiving platform-containing or receiving image field area. An image magnifying lens system is interposed between the cathode ray tube face and image field area so that an enlarged image of the cathode ray tube face of about the same size as the hard copy is focused in the same plane in said area as the hard copy would occupy if present on the platform. When the cathode ray tube image is present, the platform, which is preferably white opaque, is moved away from the image area so that the light image thereon is directed up into the image-reducing projection system.
