DOCUMENT ENTRY SYSTEM UTILIZING ELECTRONIC PEN WITH WRITTEN CONTENT ALTERATION PREVENTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To eliminate the possibility that electronic information entered to paper for electronic processing by means of an electronic pen in an initial period is rewritten intentionally or accidentally in a document entry system utilizing the electronic pen having a written content alteration preventing function.

SOLUTION: A means is provided for printing a new fine pattern in an area where it is desired to inhibit addition and correction in once filled-in electronic processing paper. By the printing, the fine pattern is added to an originally existing dot pattern on the electronic processing paper and an information input by the electronic pen is made impossible in principle.
