Abstract
A position detecting device and a position pointing device thereof, which are capable of transmitting much information at high speed without lowering the sampling rate of coordinate detection. The position pointing device controls the resonance characteristic of a resonance circuit to one of at least four different resonance characteristics in accordance with at least two bits of binary code out of a plurality of bits of binary code, which represent pointing device information, at a preselected timing. A tablet detects the resonance characteristic of the resonance circuit by resonance characteristic detecting means from an electric wave generated from the resonance circuit at the preselected timing and converts it into at least two corresponding bits of binary code, thus enabling the transmission of information of two bits or more at a time.
