Patent ID: 7321361

Claim:
A coordinate input device comprising: coordinate input means which performs a coordinate input operation by detecting a position of an external operating member that contacts a non-rotating operation surface when the external operating member slides on the non-rotating operation surface, wherein a flat base supports the non-rotating operation surface and is disposed under the non-rotating operation surface; wherein the non-rotating operation surface is capable of having a plurality of shapes and the non-rotating operation surface is formed in a convex shape, a concave shape, or the shape of a polyhedron, and wherein the non-rotating operation surface is convex or concave at the side at which the operating member slides thereon; wherein the coordinate input means comprises a capacitive sensor substrate which is formed in one of a convex shape, a concave shape and the shape of a polyhedron, and which includes a dielectric layer and two electrode layers which are laminated with the dielectric layer therebetween, each electrode layer having a plurality of electrodes arranged in a pattern.
