PURPOSE:To realize to total cost down with high reliability, by providing a detection plate in the center of a running path with a suitable interval. CONSTITUTION:A position detector 21 detects the position of a car body to a running path with a detection signal from a coil 14. The detector 21 picks up the output difference of coils 14a and 14b as an amount of deviation and detects the deviation of center position of the running path of car body. A function operating device 22 outputs (b) a correction correcting the position of the car body during driving from the position detector 21. A count signal (c) from the detector 21 is inputted to a course controller 23. The controller 23 stores information performing the change of course in accordance with the amount of detection of the detection plate on the objective course for the unattended car. |
