摘要

DRY PROCESS PRODUCTION AND ANNOTATIONOF ARCHIVAL MICROFORM RECORDSFROM HARD COPYAbstract of DisclosureLight reflected from hard copy is reduced to microimagesize and applied at an imaging and developing station to a dry-process mask film strip which is photosensitive to the reflectedlight and which is developed by heat to provide microimagedtransparencies therein. Such microimaged transparencies in the maskfilm strip are transferred in an image transferring station to a dryprocess microform film which has archival properties and which issensitive to and imaged and developed by raidant energy above a cer-tain critical value applied thereto through the mask film strip toprovide imaged microform records therein which conform to the trans-parent microimages in the mask film strip and which have archival ,properties. The imaging and developing station includes a platformfox receiving the hard copy and a projection means for applying thereduced microimage of the hard copy to the mask film strip for pro-ducing the microimaged transparencies therein and for providing theimaged microform records in the microform film. Means are providedfor moving a desired imaged microform record in the microformfilm to the imaging and developing station, and means, includingsaid projection means, are provided for expanding and projecting animage of said desired imaged microform record in the microform filmin expanded normal size onto the platform for viewing the same.additional hard copy may be received on the platform in specificrelation to the expanded normal size image projected onto the plat-form for annotation purposes, and the light image reflectedfrom the additional hard copy may be reduced to microimage sizeand applied to the mask film strip for producing a microimagedtransparency of the additional hard copy therein and for providingan imaged microform record of the additional hard copy in thedesired imaged microform record of the microform film previouslyprojected onto the platform for annotating the same with theadditional hard copy. The microform film is preferably in micro-fiche form wherein the imaged microform records therein are arrangein frames. The microform film is preferably positioned in theimage transferring station and moved to the imaging and developingstation by an X-Y carriage carrying the microform film. Thephotosensitive mask film strip is preferably carried in amovable cassette.
