Abstract
Disclosed herein is a digitizer including: a driving coil supplied with current to induce a magnetic line of force; a sensing coil disposed so as to intersect the driving coil to flow induced current in one direction by the magnetic line of force; and a control unit sensing variation of voltage induced to the sensing coil to calculate coordinates of the input unit when the voltage is changed due to an approach of an input unit.
