Abstract

PURPOSE: To improve the operability by using a translucent digitizer and providing an image forming means forming image of the content of a display section to the translucent digitizer between the digitizer and the display section so as to eliminate a parallax between a pen tip and the display section.
CONSTITUTION: When a pen 11 is pressed down to the translucent digitizer 12, an AC magnetic field reaches the digitizer 12 from the pen 11. Minute conductors wired in a lattice exists in the digitizer 12, a potential is generated to a depressed part of the pen 11 and a current flows. This is detected by a coordinate position detection section 13, the coordinate of the depressed position is calculated and transmitted to a display drive section 14. The drive section 14 lights the display part of the said position to a display 15 possible for dot display in response to coordinate position information. The lighted part is formed to the digitizer 12 via a flat lens 16 and the display part appears the depressed position of the pen 11. A character or drawing is drawn by displaying additionally the displayed part attended with the movement of the pen 11.
