A coordinate determining device comprised of a tablet having a plurality of sensing lines disposed thereon, and a magnetic field generator positionable relative to the sensing lines for indicating the coordinates of the magnetic field generator position. Detecting circuitry detects induced electromotive voltages from the sensing lines, and an arithmetic control unit computes the position of the magnetic field generating coordinate indicator and corrects for position errors caused by inclination of the magnetic field generating coordinate indicator relative to the tablet having the sensing lines disposed thereon.
