Abstract

PURPOSE:To constantly enable detection of the position of the moving body by mounting a plurality of resonant circuits having different resonant frequency in different positions in relation to the moving direction on the moving body and by arranging the same so that they are not present concurrently on the crossing point of a plurality of observing couples. CONSTITUTION:Two resonant circuits 2A and 2B whose resonant frequencies are fA and fB are mounted in the moving direction at a distance from each other on the moving body 1. When a transmission signal of frequency fA is transmitted from a transmitter 5 to a transmitting couple 4 fixed along the moving path of the moving body 1, the resonant circuit 2A resonates and a voltage VrA delayed in phase at 90 deg. from the voltage VoA of the transmitting couple is induced in the resonant circuit 2A, whereby a voltage delayed in position at 90 deg. from VrA is induced in a reference couple 60 and in each of observing couples 61-6n. Since the resonant circuit 2A stops at the crossing point of each of observing couples 62-6n, it can not be compared in phase with the reference couple 60 and consequently, detection of the position thereof can not be conducted. However, when the resonant circuit 2B is made to resonate by a transmission signal of frequency fB, the detection of the position is conducted, since the resonance circuit 2B is not present at the crossing point. Accordingly, the position of the moving body 1 can constantly be detected.
