PURPOSE:To allow a vehicle to move to and return from an optical branch path by using selectively signals from couples of sensors which detect the inside and outside of the right and left sides of a guide line formed of a beltlike light- beam reflecting surface. CONSTITUTION:The automatic running car 1 is provided with the couples of sensors 9a and 9b, and 10a and 10b which detect the inside and outside of the right and left sides of the guide line made of the optical reflecting surface, and signals from the respective sensors are inputted to a controller CT13 for steering. A position detection sensor 12 when detecting mark 11 to be detected which is stuck on the run path at a necessary part inputs a detection pulse to an arithmetic circuit 14. When the position where the sensor 12 detects the mark 11 coincides with the branch position of run information, the circuit 14 outputs a right turn command 20 or left turn command 21 to the CT13 according to the direction of the information 15. The CT13 selects signals of the sensors 9a and 9b or 10a and 10b and drives run wheels 2 to turn right or left to a run path 27 or 28. |
