Input apparatus

摘要

An input apparatus includes a base material facing the outside and configured to serve as an operation surface of the input apparatus; a substrate arranged so as to be on the inner side, i.e., the opposite side to the operation surface of the input apparatus, and so as to face the base material; at least one first pad arranged on the substrate so as to face the base material via a dielectric member and configured to detect a capacitance; at least one second pad arranged on the substrate so as to face the base material with an air layer therebetween and configured to detect a capacitance; and a control section connected to the first and second pads, and configured to control the first and second pads.

1. An input apparatus comprising:
a base material configured to serve as an operation surface of the input apparatus; a substrate arranged so as to face the base material; at least one first pad arranged on the substrate so as to face the base material with a dielectric member therebetween and configured to detect a capacitance; at least one second pad arranged on the substrate as to face the base material without a dielectric member therebetween and configured to detect a capacitance; and a control section connected to the first and second pads, and configured to control the first and second pads, wherein the second pad is configured to determine a correction value, with which the control section or a central processing unit connected to the control section adjusts an output of the first pad on the basis of an output of the second pad.
