  • Publication number: 20250068265
    Abstract: An electromagnetic induction pen of an electromagnetic induction system (EMR) system that can achieve a multilevel pen signal. The electromagnetic induction pen includes a resonance circuit that transmits a pen signal by using power obtained from an alternating magnetic field sent out by a position detecting device, and a control circuit that causes the resonance circuit to transmit the pen signal phase-modulated according to information to be transmitted to the position detecting device, by temporarily changing a resonance frequency of the resonance circuit from a first frequency to a second frequency different from the first frequency based on the information and then returning the resonance frequency of the resonance circuit 23 to the first frequency.
