COORDINATE DETECTION APPARATUS
First Claim
1. A coordinate detection apparatus comprising:
- a resistance-film formed on a substrate made of an insulating material;
a common electrode configured to apply a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film; and
a voltage application part configured to apply the voltage to the common electrode,wherein the voltage is applied from the voltage application part to the resistance-film through the common electrode to generated a potential distribution in the resistance-film; and
wherein a coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.

Abstract
In a coordinate detection apparatus, a resistance-film is formed on a substrate made of an insulating material. A common electrode applies a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film. A voltage application part applies the voltage to the common electrode. The voltage is applied from the voltage application part to the resistance-film through the common electrode to generate a potential distribution in the resistance-film. A coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.
