ABSTRACT:
In this digitizer, when the coil of the position indicator is placed near a plurality of conductors of the tablet, an oscillator arrangement is formed through the amplifier, and a position indicated by the position indicator is determined by detecting magnetic fields generated by the position indicator when the oscillator arrangement oscillates. In addition, when the position indicator is placed near the tablet, an oscillator arrangement is constituted by the position indicator and two conductors of the tablet at a timing at which the position of the position indicator is measured.
