Abstract

PURPOSE: To easily and naturally execute the erasing operation at the time of handwriting input executed by a stylus pen by providing a first sensor for coming into input-contact at the time of entering a handwriting input, and a second sensor for coming into line or face-contact at the time of erasing partially information on both ends of the stylus pen.
CONSTITUTION: A writing sensor 2 is provided on the tip A of a stylus pen 1, and an erasing sensor 3a is provided on the other end B. The writing sensor 2 is used as a sensor at the time of writing (at the time of entry), and formed projectingly so as to come into point-contact with a tablet. The erasing sensor 3a is used for erasing a character and a graphic, etc., written by the writing sensor 2, and formed in a plate-like shape so as to come into face-contact or line-contact with the tablet. In such a way, a handwriting input of a natural operating sense is executed and the operation is executed easily, and also, at the time of erasure, an area of the contact part is larger than that at the time of writing, therefore, erasure is executed without tracing exactly handwriting at the time when it is executed.
