Document scanning system with dockable platen flatbed providing sheet fed and platen scanning functions

摘要

A scanning system which supports platen and sheet fed scanning of documents comprises a first scanning unit with a first enclosure housing a first set of mechanisms enables full sheet fed scanning functions. A second set of mechanisms enables partial scanning functions. The first scanning unit also comprises a docking interface defining an opening of the first enclosure. A second scanning unit with a second enclosure is capable of attachment to the first scanning unit through the docking interface and includes a third set of mechanisms which enables complete platen scanning of documents in operable combination with the second set of mechanisms.
