Claim:
1. An apparatus for measuring a position of a touch by an object on a device including the apparatus, comprising: an electrode unit comprising an X-axis direction electrode unit and a Y-axis direction electrode unit for sensing a capacitance or voltage variation caused by a touch of the object; sensing electrodes included in the electrode unit and formed in two crossing directions of the X-axis and the Y-axis for sensing a touch of the object on a plane; connectors included in the electrode unit for electrically connecting the sensing electrodes to the control circuit unit; independent channels connected to independent connectors among the connectors, which are included in the electrode unit for the sensing electrodes arranged in at least one of the two crossing directions, the independent connectors connecting a subset of the sensing electrodes independently to the control circuit unit via said independent channels; and multi-channels included in the electrode unit and comprising connection ports connected to connection lines that feed to common connectors among the connectors, the common connectors connecting the remainder of the sensing electrodes commonly to the control circuit unit via said multi-channels, wherein the position touched by the object is measured using the sensing electrodes arranged in the two crossing directions, the sensing electrodes arranged in one direction include independent channels and the multi-channels, and the sensing electrodes arranged in the other direction perpendicular to the one direction include only independent channels, wherein the X-axis electrode unit having the sensing electrodes arranged in the X-axis direction and the Y-axis electrode unit having the sensing electrodes arranged in the Y-axis direction are layered on opposite surfaces with an insulation layer interposed in between, and wherein insulation members are formed on the insulation layer to insulate intersection points of some of the connection ports that intersect one or more of the connection lines connected to others of the connection ports, and conductive patterns are formed on the X-axis electrode unit in order to electrically connect said some of the connection ports to their corresponding one or more connection lines at said intersection points and over said insulation members.
