    摘要: A device for identifying the location and type of an object according to the present invention comprises: a transmission and reception coil in which a conductive wire is wound concentrically and multiple times; a selection circuit for selectively connecting one end portion of the conductive wire of the transmission and reception coil to a first circuit end or a second circuit end; an output circuit formed to apply an alternating current of a first frequency to the first circuit end; a reception circuit for receiving an induced voltage applied to the second circuit end; and a control circuit for controlling the operation of the selection circuit to connect the output circuit to the one end portion of the transmission and reception coil in a transmission mode and connect the reception circuit to the one end portion of the transmission and reception coil in a reception mode, controlling the output circuit to apply the alternating current of the first frequency to the first circuit end in the transmission mode, and determining if a predetermined resonant circuit has come near the transmission and reception coil, by analyzing the peak or strength of the induced voltage received by the reception circuit in the reception mode.
