The present invention includes: a driving coil which induces magnetic field lines when a current flows through; a sensor coil which arranged to intersect the driving coil and wherein an induced current flows in one direction by the magnetic field lines; and a control unit which calculates the coordinates of the means of inputs when the voltage induced by the sensor coil changes as the means of inputs approach by sensing the variation of the induced voltage.
