SIGNAL TRANSMITTING APPARATUS

WIPO Patent Application WO/2011/111168

A1

Disclosed is a signal transmitting apparatus wherein planar coils are respectively used as a transmitting coil and a receiving coil. The outer diameter of the transmitting coil and that of the receiving coil are reduced, and signals are stably transmitted from the transmitting side to the receiving side. The signal transmitting apparatus is provided with: the transmitting coil, which is driven corresponding to input signals; the receiving coil, which outputs receiving signals when the transmitting coil is driven; a preprocessing circuit, to which the receiving signals outputted from the receiving coil are inputted; and a detecting circuit, which detects the input signals from the signals outputted from the preprocessing circuit. The preprocessing circuit converts the receiving signals outputted from the receiving coil into the signals, which are within the frequency range wherein the detecting circuit can receive the signals, and which have a voltage equivalent to the withstand voltage of the detecting circuit or lower, and the preprocessing circuit outputs the converted signals.
