Abstract:
A multidirectional input device comprising:an insulating substrate; a ring-shaped resistance element layer formed on said insulating substrate, said ring-shaped resistance element layer having a plurality of electrodes disposed thereon; a plane substrate spaced from said resistance element layer by an insulating space; a ring-shaped conductive section disposed on said plane substrate; an operating section operable to bring said resistance element layer into partial contact with said conductive section; and a controller, wherein said ring-shaped conductive section comprises a plurality of conductive layers insulated from each other by insulating sections, wherein said insulating sections oppose said plurality of electrodes, wherein said resistance element layer is operable to receive a voltage, wherein said operating section is further operable to press one of said insulating substrate and said plane substrate so that said resistance element layer comes into partial contact with said conductive section, and wherein said controller is operable to detect a contacted position between said resistance element layer and said conductive section using a signal supplied from said conductive section.
