Abstract

PURPOSE:To make unnecessary a stylus and to increase the operativity, by constructing a spacer in which the pressed part is conductive is clipped with resistance plates with flexibility and the coordinate is detected by pressing the resistance plates. CONSTITUTION:A resistance plate 1 having flexibility has two sets of opposing electrodes. The power supply V1 is fed between the electrodes A and B via the switch S1 and the power supply V2 is fed between electrodes C and D via a switch S2. The resistance plate 1, insulating spacer 4 and electrode plate 5 are overlapped, the detector 3 is connected between the electrode plate 5 and ground. The detection signal indicating the coordinate on the plate is obtained at the detector 3 by pressing the part on the resistance plate 1 with a finger or a rod. This detection signal is converted into a digital signal at an A/D converter 6, and the signal (x) for the coordinate X is stored in the register 7 and the signal (y) of the coordinate Y is stored in the register 8. The control circuit 9 corrects the content of the registers 7 and 8 by using the conversion table 10. This correction is made by converting the value into a value obtained at a linear equi-potential plane.
