PROBLEM TO BE SOLVED: To provide a technique for positioning an unmanned carrier to a stop position accurately at short time.SOLUTION: A positioning device 1 is constituted of a moving member 20 attached to an unmanned carrier 2, and a correction member 60 installed on a position corresponding to a stop position of the unmanned carrier 2 at a station S. The moving member 20 is moved to a correction position of a lateral position for correcting a lateral position of the unmanned carrier 2. In addition the moving member 20 is moved to a correction position of a cross direction position from the correction position of the lateral position, for correcting a cross direction position of the unmanned carrier 2. Because it has a simple structure in which the moving member 20 is only moved to a lower vertical direction with two stages, so that the unmanned carrier 2 can be positioned to the stop position accurately at short time with a simple structure. |
