ンス変化を検知するよう構成されている。In these systems, a guideway is formed by attaching a metal band to the road surface on which the guided vehicle should travel, and the guided vehicle learns the direction of travel from the signal from the metal detector attached to the guided vehicle. By steering the vehicle accordingly, it guides the vehicle to its destination. This metal detector usually works on the following principle. As shown in FIG. 4, the metal detector 9 has an oscillator 3 and a coil 4 that generates a magnetic field. The magnetic flux 7 generated by the coil 4 induces eddy currents 6 in the metal strip 5 that approaches it. The magnetic flux 7 generated by the eddy current 6 is in a direction (in the opposite direction) that cancels out the magnetic flux 8 generated by the coil 4. This magnetic flux 7 changes the magnetic field around the coil 4, or
Effects such as changing the impedance of the coil 4 are produced. The metal detector 9 is configured to detect these changes in magnetic field and impedance.
