  • Patent number: 4929934
    Abstract: In a pressure-sensitive input apparatus comprising an X-coordinate detection resistive member connected to mutually parallel vertical electrodes and a Y-coordinate detection resistive member connected to mutually parallel horizontal electrodes, for detecting the position of a point depressed by a stylus or the like, by detecting changes in the resistance values of these resistive members, switches are provided for on-off control of the current flowing into or out of both ends of the X-coordinate detection resistive member and the Y-coordinate detection resistive member, and a voltage detection circuit detects the voltage between the X-coordinate detection resistive member and the Y-coordinate detection resistive member. Multiple inputs can be detected according to the results obtained from the voltage detection circuit when the currents are switched by the switches.
