- an electrode part 3 facing the electrode part 2 is arranged, and the electrode parts 2 and 3 and the panel part 1 form a capacitor.
- the oscillation unit 4 outputs a high frequency voltage, and this high frequency voltage is applied to the electrode unit 3.
- Oscillator 4 has a high output impedance.
- the rectification unit 5 rectifies and smoothes the high-frequency voltage output from the transmission unit 4, that is, the high-frequency voltage applied to the electrode unit 3, converts it to a DC voltage, and outputs it to the voltage-dividing unit 12.
- the DC voltage is higher when the electrode part 2 is not touched than when the electrode part 2 is touched.
- the voltage divider 12 divides the DC voltage output from the rectifier 5, and outputs a DC voltage whose absolute value is smaller than the DC voltage output from the rectifier 5 to the determination unit 13.
- the judgment unit 13 calculates the potential difference between the potentials before and after the change.
- the determination unit 13 determines that the electrode unit 2 has been touched with the finger 9 when the voltage difference is equal to or greater than a predetermined value. Since the DC voltage output from the rectifier 5 has a large absolute value, if it is input to the determiner 13 as it is, the determiner 13 may be destroyed or malfunctions may occur. In order to prevent this, the voltage output from the rectifier 5 is divided by the voltage divider 13 and lowered to a predetermined level.
