ABSTRACT:
A filing system scans original documents and converts the information on the documents into picture information which is then condensed and stored in a file storage block. If an index for the files is specified, an index of the picture information is stored in a file image memory having a plurality of fixed memory areas. Coordinates of an area of the original document enclosing the picture information on the original document can be specified, and tables in memory indicate the correspondence between specified areas, the corresponding fixed memory areas in the file image memory, and the addresses of the corresponding stored files. To retrieve the files, an operator can either press certain areas on a document with a stylus pen, provide an identifier of the files, or place marks on an index document prepared by the filing system.
