Document processing device

摘要

A document processing device for use in combination with a printed document which carries at least one document identification marking comprises a position sensing means which includes one or more sensors adapted to track the movement of a pen or stylus relative to the sensors thereby to produce one or more signals indicative of the location of strokes made by the pen relative to a document located on a support surface associated with the positions sensing means, and a code reading means which is adapted to detect a document identification marking carried by the document and to generate a document identification signal indicative of the identity of the document. The document identification marking is preferably a barcode. The pen or stylus is preferably tracked using induction, triangualaton or touch sensitivity.
