Abstract
PURPOSE: To enable to obtain the detection of the position of pressure input as the voltage dividing ratio of the surface resistor, for example, opposing to the surface electrode.
CONSTITUTION: When letters are described on suitable paper on the protection sheet 16 while depressing with a ball point pen, it is delivered to the surface electrode 12 via the shield electrode 15 and insulation sheet 14, and the resistance at the corresponding position is reduced by exerting pressure on the pressure sensing distribution switch layer 13 corresponding to the depressed position. Thus, the surface electrode 12 and the surface resistor 11 are electrically connected, and the power supply 17 is connected to 11 through the said pressure resistance section. A given voltage E is fed toward X axis opposing to the surface resistor 11, and the voltage VP at the point P where the given voltage of the power supply 17 is fed through the low resistance section formed on 13 corresponding to the pressed point has the relation of R1/l=VP/E. The pressed point is detected from this, and the position of the information inputted can correctly and easily be known.
