PURPOSE:To obtain durability and to realize an unmanned run free of deterioration in function by providing and magnetizing a guide line coated with magnetic paint on a running path surface, and running an unmanned running truck equipped with a magnetic force detector. CONSTITUTION:The running path surface 1 is coated with the paint 2 containing mixed magnetic powder. Then when a magnet 3 is put close onto a guide path 2 of magnetic powder made of the paint, the guide path 2 is magnetized permanently. When the magnet 3 is moved along the guide path 2 closely, the magnetic path is magnetized only in the range. Then, the truck is placed on the road surface 1 so that magnetic force detectors 6 and 7 loaded on the truck 5 are positioned on the left and right sides of the guide path, and consequently the left and right detectors 6 and 7 detect the magnetic field 8 produced by the guide path 2. Then, the truck 5 is run automatically along the guide path 2 by being controlled so that the detected magnetic forces of the left and right detectors are equalized to each other. |
