A nearly mean value of a half wave rectifier signal of the signal received by the transmission reception coil 31 is outputted from the one detection circuit and envelope detection signal of the ASK signal is outputted from the other detection circuit. The DC component from the ASK envelope detection signal is cut off by the capacitor 40 and the result is inputted to a CMOS buffer 42 and the CMOS buffer 42 is biased by using the mean value voltage via a resistor 39 to allow even a small level signal to exceed a threshold level thereby improving the reception sensitivity.
