PURPOSE:To exactly load an unattended carrier car on the reference path, by a simple means, by providing a photoelectric tube by turning control for scanning a recurrent type passive reflector located at the side which is nearer the reference path, whenever it runs by a prescribed distance, on the unattended carrier car. CONSTITUTION:When an attended carrier car has funished turning by a gyrocompass, recurrent type passive reflectors 2a-2e are scanned by a photoelectric tube 3, and at first the passive reflector 2a is selected. Accordingly, a correcting angle is inputted to a steering wheel driving circuit 9 from an operating circuit, the steering wheel is turned toward the passive reflector 2a, and a carrier car 1 runs, making the passive reflector 2a a target. When the carrier car 1 runs by a distance L1, the passive reflector 2b is scanned by the photoelectric tube 3. When the passive reflector 2b is operated, the direction of the carrier car 1 is converted toward the passive reflector in the same way, and it runs in this direction. When the carrier car 1 runs by a distance L2 in the direction of the passive reflector 2b, subsequently the passive reflector 2e is scanned by the photoelectric tube 3, and the carrier car 1 runs by the residual distance L3 in the direction of the passive reflector 2e. |
