The tablet has an electronic energy transmission circuit for wirelessly supplying electronic energy for operating the electronic pen, and a stylus pressure detection circuit for detecting the stylus pressure by receiving an electronic signal transmitted from the electronic pen and measuring a signal frequency. The electronic pen has an electronic energy receiver for converting the electronic energy obtained by wireless transmission from the tablet into a direct current power source. The stylus pressure transmitter circuit powered by the electronic energy receiver modulates a high frequency carrier wave according to the stylus pressure. Send a signal The frequency of the stylus pressure transmitting circuit in the electronic pen is modulated according to the stylus pressure, and transmits a carrier wave of a frequency different from the frequency of the electron energy transmitted by wireless from the tablet to the electronic pen.
