PURPOSE:To simplify the construction work of a marker line and the structure of a sensing means by simply changing the magnetic pole of the marker line to automatically switch S-shaped or sigzag traveling or fixed route traveling. CONSTITUTION:When a player sends a start signal by means of a near-by remote control originator, a cart starts to advance. Since the magnetic sensors 4 to 7 of the cart 3 read out the magnetic pole (S pole) of the fixed route traveling part B of the market line 2, the cart 3 advances along the line 2 so as to trace the line 2. At the time of sensing the magnetic pole (N pole) of the S-shaped or zigzag traveling part A, the cart 3 executes S-shaped or zigzag traveling in either one of traveling routes C, D. Thus, the cart 3 can advance while automatically changing its traveling between the S-shaped or zigzag traveling and fixed route traveling. |
