In an improved system for loading new microfiches, or updating previously stored microfiches, in a microfilm cassette library; a registration mode is provided whereby a keyboard operator can register keyword a and other index information for specific frames while these microimages are concurrently being projected on a viewing screen. Structures are included for receivingand holding fiches or cassettes being registered, for positioning frames for optical projection, and for reading magnetically encoded fiche identity data. Both buffer memory and file memory means are provided for storage of frame address information including cartridge identity, microfiche identity, X and Y axes coordinates, and other index data. Microcomputer means are provided for overall control of the registration of new fiches and for retrieval of same.

Microimage registration system for loading and/or updating microfiches

A microfiche retrieval scheme having input means for introduction of index information indicative of desired subjects for retrieval, store means which provide pieces of frame address information for one or more microimages concerning the desired subjects in response to the index information and an optical system for projecting the selected microimages onto a viewing screen in accordance with the thus delivered frame address information. The above scheme further comprises a printer adapted to print out information contained on the microimages selected and transmitted to the optical system, a print control adapted to control the microfiche retrieval scheme and the printer and means for providing for the print control a signal indicating the printing out of the information of the selected microimages or that of their next succeeding microimages.
