Abstract

PURPOSE: To miniaturize a device with input position precision improved while simplifying its structure, by detecting position information on an electrode through a resistor which has uniform resistance per unit length.
CONSTITUTION: On fixed plate 1, 1st parallel electrode group 2 having flexibility and 2nd parallel electrode group 3 having flexibility as well are arranged crossing at right angles and opposing to each other, and the 1st resistor 4 and the 2nd resistor 5 with electrodes 6W9 are brought into contact with the terminal parts of parallel electrode groups 2 and 3, thereby constituting an electronic input plate. Between terminals (a) and (c) of electrodes 6 and 8 of resistors 4 and 5 on this input plate, constant current source 12 supplying a current and current detecting circuit 19 detecting currents leaking to resistors 4 and 5 and while differential amplifiers 13 and 14 connected to X and Y output terminals 17 and 18 are connected to terminals (b) and (d), touch output terminal 20 outputting position information is connected to circuit 19. Then, circuit 19 detects position information with high precision and this device is miniaturized with its structure simplified.
