Abstract

PURPOSE:To omit the power battery of a mobile transponder by rectifying and charging a reception output in a capacitor in the mobile transponder, and feeding electric power from the capacitor to a transmitting and receiving circuit when a switch circuit is in operation. CONSTITUTION:A radio wave source 130 which sends out a specific radio wave of frequency different from a radio wave for answering is provided on the side of a fixed transponder 100, and an antenna 231 which receives the specific radio wave, a rectifying circuit 232 which rectifies the reception output, the capacitor 233 which is charged with its rectification output, and the switch circuit 234 which operates when its charging voltage exceeds a specific threshold value, are provided on the side of each mobile transponder 200. The operation threshold value of the switch circuit 234 is set higher than the lowest operating voltage of the transmitting and receiving circuit 220 in the mobile transponder 200 and the transmitting and receiving circuit 220 is powered up by the capacitor 233 in the operation of the switch circuit 234.
