Patent ID: 8223132

Claim:
A capacitive touch pad apparatus, comprising: a plurality of first electrodes positioned on a substrate; a plurality of second electrodes positioned on said substrate so as to substantially encircle at least one of said plurality of first electrodes; a plurality of first conductive lines extending from at least one of said plurality of first electrodes along said substrate, with at least one of said plurality of first conductive lines positioned between at least two of said plurality of second electrodes; an insulating sheet, having one primary surface exposed to outside, for covering said plurality of first electrodes, said plurality of second electrodes, and said plurality of first conductive lines a detector for detecting a change in capacitance of each of said plurality of first electrodes and said plurality of second electrodes; and a processor for executing a process that is referred to a plurality of detection results by said detector wherein the detection results of said detector indicate one of active and negative, and said processor includes a determiner for determining whether or not both detection results, out of a plurality of detection results by said detector, corresponding to said plurality of first electrodes are active, a first predetermined process executor for executing a first predetermined process when a determination result of said determiner is affirmative, and a second predetermined process executor for executing a second predetermined process when the determination result by said determiner is negative.
