Abstract

Abstract PURPOSE:To perform inputting display and handwritten inputting and display by superposing a transparent digitizer and a display unit to form a touch panel. CONSTITUTION:A touch panel 21 is constituted by superposing a transparent digitizer 1 and a display unit 2 that displays handwritten characters, graphics and function switches. Positional coordinates are inputted by bringing an inputting pen 3 into contact with the transparent digitizer 1, and an output from the digitizer 1 is converted to coordinate data in a transparent digitizer controlling section 4. A controlling section 7 displays handwritten information in a display unit 2 through a display controlling section 5, and at the same time, sends out to a communication circuit 20 through a communication processing section 10. Information displayed on the touch panel is stored in a file memory 15.
