INPUT DEVICE
First Claim
1. An input device comprising:
- an input electrostatic sensor;
a noise detection electrostatic sensor; and
a control means that compares an output signal obtained from the input electrostatic sensor with a noise signal obtained from the noise detection electrostatic sensor, determines the output signal obtained from the cause different from the approach or the contact of the potion of the human body to a noise component, and controls an input operation.

Abstract
Provided is an input device capable of determining an output signal according to approach or contact of a portion of a human body and an output signal including noise to perform an input operation, although the output signal output from an electrostatic sensor includes the noise.
The input device includes an input electrostatic sensor 2 which detects whether a portion of a human body approaches or makes contact by change in capacitance, a noise detection electrostatic sensor 3 which is provided on the periphery of the input electrostatic sensor 2 and detects change in capacitance which is generated by a cause different from the approach or the contact of the portion of the human body, and a control means 9 which compares an output signal obtained from the input electrostatic sensor 2 with a noise signal obtained from the noise detection electrostatic sensor 3, determines the output signal obtained from the cause different from the approach or the contact of the potion of the human body to a noise component, and controls an input operation.
