PURPOSE:To automatically move a service car to a part corresponding to the next beam light projecting position, by detecting a fact that the service car guided by a beam light has reached a terminal part of the work process. CONSTITUTION:The projecting direction of a beam light A projected from a laser light projecting device 1 is controlled automatically so as to become parallel in the respective work processes. An optical sensor S5 for detecting a service car photodetects a light beam projected from a projector 14 provided on the front of a service car V1, and detects a fact that the service car V1 has reached a terminal part of the work process. A moving body V2 starts to move, based on detection information of the sensor S5, and also, stopped automatically, when a proximity sensor S4 detects a positioning use hole 2 formed in a guide L. Subsequently, based on detection information of a sensor S3 for the beam light projecting direction, the projecting direction of the beam light A is controlled automatically. |
