Abstract:
An input device includes a voltage divider circuit that includes a resistive sensor whose resistance changes in accordance with a change in pressure of a pressing operation and at least one resistor device and that, upon receiving driving voltage, generates a divider voltage according to the resistance of the resistive sensor device, a first driving circuit that alternately supplies, to the voltage divider circuit at certain time intervals, a first driving voltage and a second driving voltage for generating different divider voltages, a capacitor whose charge changes in accordance with a change in the divider voltage, and a first charge detection circuit that detects an amount of change in the charge of the capacitor at a time when the driving voltage changes from the first driving voltage to the second driving voltage and when the driving voltage changes from the second driving voltage to the first driving voltage.

Claim (Index 4):
The input device according to  claim 2 ,\n wherein the voltage divider circuit applies the divider voltage to one end of the capacitor, and wherein the first charge detection circuit includes a charge-transfer capacitor that accumulates charge transferred from another end of the capacitor, an amplifier circuit that amplifies a difference between a voltage at the other end of the capacitor and a reference voltage and that outputs a resultant voltage to the charge-transfer capacitor, and a charge initialization circuit that, after the amplifier circuit outputs a voltage according to charge transferred to the charge-transfer capacitor from the capacitor in accordance with a change in the driving voltage, initializes the charge accumulated in the charge-transfer capacitor before the driving voltage changes again.
