Abstract

PURPOSE:To enable to detect the position without loading the oscillator on moving body, by detecting the resonance of resonance circuit of the moving body by the transmission couple, by the observation couple which is electromagnetically combined with said circuit. CONSTITUTION:A resonance circuit 6 of a moving body 1 resonates through a fixed transmission couple 7 which is excited by a oscillator 2. Said resonance is observed by a fixed standard couple for a phase standard 30 which is electromagnetically combined with the circuit 6 and an observation couples 31... crossing in a definite state and then, detecting signal in accordance with the position of the body 1 is generated. Accordingly, the position of the body 1 can be detected without loading the oscillator on the body 1 and also, without supplying electric power for oscillation.
