Abstract

PURPOSE: To detect accurate designated position from the ratio of ground potential, by making the shunt flow pattern in the sheet almost uniform except the vicinity of flowing point, through the forming of a resistance sheet into a fancy paper and arrangement of a plurality of papers with slight distance each other.
CONSTITUTION: An X axis resistance sheet 20 used for a tablet input device is formed into a fancy papers to constitute a plurality of resistors 21 with slight distance each other. Further, electrodes 22, 23 equipped incorporatedly are provided with one end 21A and another end 21B of a plurality of resistors 21. Further, the consturction of the Y axis resistance sheet is formed the same as the X axis resistance sheet 20. Further, when the input pen is indicated for the position in contact with the point PX of the tablet, the currents I1, I2 flowing to the resistor 21 are designed so that they flow almost uniformly except the vicinity of the point PX and flow into ground through the electrodes 22 and 23, allowing to detect the accurate disignated point from the ratio of ground potentials.
