Abstract

Abstract PURPOSE: To enable an electronic identifying device to receive rough information and detailed information by providing a reception circuit which is adapted itself to take a first mode for forming a narrow band tuning circuit and a second mode for forming a wide-band circuit to a responder. CONSTITUTION: A responder is provided with a coil 3 which can relatively form a narrow band tuning circuit together with a switch element 4, namely, a capacitor 5 and can relatively form a wide-band circuit when the coil 3 is disconnected from the capacitor 5. A digital circuit 6 switches the element 4 by detecting the intensity of the electric field formed by the coil 3.
