US 2014/0192273 A1 · INPUT DEVICE

Abstract

An input device includes: an operation panel including: a plurality of first conductive patterns that extend in a first direction, and are arranged in a second direction crossing the first direction; and a plurality of second conductive patterns that extend in the second direction, and are arranged in the first direction; an indicator that includes a charge unit charged with electric charges; and a position detection unit that, when the indicator comes close to the operation panel, measures electric potentials by electric charges which arise in the first conductive patterns and the second conductive patterns by the charge unit of the indicator, and detects a position of the indicator based on a measurement result of the electric potentials.
