ABSTRACT:
This relates to a high capacity, high speed random access filing system for graphic data. Graphic data on microfilm is placed in cartridges and the cartridges stored in a storage drum. The location of each cartridge is defined by a four digit address and each image frame is further defined by a four digit address. A source document is accessed by entering the combined eight digit address via a keyboard. The corresponding cartridge is automatically retrieved and the image frame corresponding to the requisitioned document is located and projected onto a display screen. A hard copy may then be produced if desired. The above system may be combined with an electronic memory search and data capture equipment for originating, maintaining, and updating stored graphical data.
