description A driving unit successively selects one drive line from among a plurality of drive lines of a touch inputting device and applies a driving voltage to the selected drive line. A voltage detection unit successively selects one sensing line from among a plurality of sensing lines and detects an output voltage of the selected sensing line. An arithmetic operation unit determines a resistance value of a pressure-sensitive resistive element provided at the location at which the selected drive line and the selected sensing line cross with each other based on the driving voltage and the output voltage. The driving unit applies 0 volts or a bias voltage equal to or lower than the driving voltage to the other drive lines than the selected drive line.
