Abstract:
A coordinate input apparatus comprising:an electrostatic capacitive detection section for detecting coordinates by operating the electrostatic capacitive detection section with an indicator so as to change an electrostatic capacitance between an X electrode and an Y electrode, which are arranged so as to oppose each other via an insulating layer interposed therebetween; and a pressure-sensing detection section having a resistor and a conductor arranged so as to oppose the resistor, the pressure-sensing detection section detecting coordinates based on a resistance of the resistor at a contact point between the resistor and the conductor when being operated with a predetermined pressure, wherein the electrostatic capacitive detection section is deposited on an operating surface side of the pressure-sensing detection section, wherein the electrostatic capacitive detection section is flexible and is capable of being pressed against the pressure-sensing detection section, and wherein the pressure-sensing detection section comprises a high resistance resistor and a low resistance resistor arranged around the high resistance resistor, a voltage being applied alternately between low resistance resistor portions opposing in an X direction and between low resistance resistor portions opposing in an Y direction so that coordinates are detected based on a voltage detected between the low resistance resistor and the conductor by causing the conductor to make contact with the high resistance resistor.
