PROPOSED COMBINATION CASE 554-557 APPARATUS FOR PRODUCING MICROFORM RECORDS FROM MULTIPLE DATA SOURCES Abstract of the Disclosure Apparatus for producing microform records from various image sources, such as hard copy or cathode ray tube images fed from various data sources,includes an image-reducing projection system into which is selectively directed light selected from hard copy or light preferably from the face of a cathode ray tube to which white background CRT image-forming signals are fed from any one of a number of selectable data sources. 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 portion thereof and most advantageously arranged as a microfiche card. A cathode ray tube image providing means is located immediately below a platform-containing or receiving image field area. The platform normally is adapted to receive hard copy thereupon. Manual controls are provided for setting-up the apparatus for producing microform records of either hard copy or cathode ray tube face images. In the latter case, the platform, which is preferably white opaque, is moved to expose the image providing means the light image thereon is directed up into the image-reducing projection system. Means are provided for deter- mining exposure times for imaging upon the mask-forming film in accordance with the average background light intensity of the light reflecting from the hard copy or the background light on the cathode ray tube image, depending upon whether hard copy or cathode ray tube image microform imaging is desired by operation of the appropriate manual controls.
