摘要 PURPOSE:To reduce the number of conductors and to provide a position detection system for moving bodies which is difficult to receive the influence of ambient noises and crosstalk by disposing N pieces of conductors of a sinusoidal wave shape with deviation from each other along a traveling path for moving bodies. CONSTITUTION:Conductors 1, 2, 3 are bent to a sinusoidal wave shape at periods P, and are laid with deviation of each P/3 from each other. Antennas 5a, 5b are disposed at a spacing DELTAZ to a moving body, and are excited by the signals of respectively different frequencies fa, fb. The signals of the frequencies fa, fb are selectively received at the beginning end of a line 4, whereby the position of the moving body is detected.
