Abstract

Document communication systems are envisioned which will achieve efficiency in their transmission links through packet switching and data compression techniques. Coupling of document scanners to such transmission links will require hardware (i.e. buffers, MODEMS) and software (i.e. for data compression). Complete stand alone systems will be of value for mailroom environments where numerous input documents can be queued up and from which output documents can be distributed. In some business environments, however, decentralization of document input ports for document communication systems may be of value by enhancing access to the system, shortening turnaround time and reducing the likelihood of security violations at the input end. These values are analogs of some of the advantages of decentralized copiers as opposed to Central Reproduction Systems. Stand alone Raster Input Scanners (RIS herein) represent one approach to provide remote input ports for document communications systems.

Document communication systems are envisioned which will achieve efficiency in their transmission links through packet switching and data compression techniques. Coupling of document scanners to such transmission links will require hardware
(i.e. buffers, MODEMS) and software (i.e. for data compression). Complete stand alone systems will be of value for mailroom environments where numerous input documents can be queued up and from which output documents can be distributed. In some business environments, however, decentralization of document input ports for document communication systems may be of value by enhancing access to the system, shortening turnaround time and reducing the likelihood of security violations at the input end. These values are analogs of some of the advantages of decentralized copiers as opposed to Central Reproduction Systems. Stand alone Raster Input Scanners (RIS herein) represent one approach to provide remote input ports for document communications systems.

It is proposed here to combine decentralized copier and RIS functions into a single dual function unit to gain efficiency in utilization of both hardware and office space. Essential hardware for either RIS or copier functions includes document handling and illumination means, optics, scanning mechanisms, frames and covers.

SELF SCANNING TONER RIS (Cont'd)

Combining RIS and copier functions, the subject of this disclosure, offers savings associated with the costs of these elements and office space efficiency inherent with single vs. dual units to achieve a dual function unit. Document handling features and precollation systems as well as optical reduction/enlargement are potential added values at shared expense in the proposed dual function unit.

Two approaches to achieving copier-RIS dual functionality are apparent. One approach is to scan the untransferred toner images on the copier photoreceptor with a flying spot beam and convert the resulting r...
