PURPOSE:To prevent a moving car from reading erroneous control information by providing a trigger magnet piece indicating the read position of a control mark so that its magnetic pole is opposite to that of a guide band. CONSTITUTION:A moving car guide band L which is magnetized to have the N pole on the front face and have the S pole on the rear face is stuck onto the traveling road surface of a moving car A along the traveling course having intersections CR, and control marks (m) on which moving car guide control information due to combination among magnetic poles of plural magnet pieces m1-m6 are displayed are provided on both sides of the guide band L. Trigger magnet pieces mT indicating read positions of marks (m) are provided so that their magnetic pole is opposite to that of the guide band L, thus preventing the moving car A from reading erroneous control information.
