COORDINATE INPUT DEVICE

摘要: PROBLEM TO BE SOLVED: To operate a coordinate input device without contact through the use of an insulating object except for finger and to sensitively precisely decide position cursor on display giving unpleasant feeling operator while power consumption is reduced. SOLUTION: An oscillation coil 2 which pattern-formed substrate 1, four resonance coils 3A-3D are 1 at equal intervals in peripheral direction capacitors provided. A shielding member 6 constituted metal material slid all directions within forming area operation 8. Following voltage changes operated moving data obtained. Then, obtained converted into signal.
