Patent ID: 8711122

Claim:
A sensor apparatus, comprising: a sensor panel that includes an input operation surface and is configured to detect positional coordinates of a detection object that comes into contact with the input operation surface; a casing; and a pressure-sensitive sensor that includes (a) a first electrode fixed on a sensor panel side, (b) a second electrode fixed on a casing side, and (c) an elastic member between the sensor panel and the casing, the elastic member elastically supporting the sensor panel with respect to the casing, the pressure sensitive sensor being configured to detect a pressing force that is input to the input operation surface as a change in a capacitance between the first electrode and the second electrode, wherein, the pressure-sensitive sensor has first and second areas between the first electrode and the second electrode, the first area having a first capacitance and the second area having a second capacitance, the second capacitance being larger than the first capacitance, the first and second areas are located along a circumferential region of the sensor panel, and the second area is located along a center axis of the pressure-sensitive sensor.
