PURPOSE:To make all workers to know the traveling path and the direction of an unmanned carrier by emitting light fro ma light emission device buried in a travel path where the unmanned carrier is expected to travel by a light emission controlling computer according to the travel path light emission command from a conveyance controller. CONSTITUTION:The conveyance controller 4 analyzes an input conveyance command to generate travel information on the unmanned carrier 1, i.e. the travel path and makes the computer 8 for light emission control to emit light from all light emission devices 7 on the travel path 2. Then, the unmanned carrier 1 is made to travel from a point A to a point B and the computer 8 for light emission control is made to blink light emission lamps 7d between the points A and B and turn off the light emission lamps 7d which blink when the unmanned carrier 1 reaches the point B. Consequently, the workers know the travel path, travel direction, and travel order of the unmanned carrier 1. |
