PURPOSE:To improve working accuracy by receiving respective light receiving quantity signals in X and Y axis directions to be enclosed from a position detector, obtaining respective dislocating quantity from a stop setting position in the X and Y axis directions of an automatically guided vehicle and correcting the working position of a manipulator. CONSTITUTION:Respective surface emitting bodies 26 and 27 are enclosed in both directions of the Y axis and X axis directions by first and second shielding bodies 31 and 32. Then, the respective dislocating quantity from the stop setting position in the X axis and Y axis directions of automatically guided vehicle 20 is obtained by the respective light receiving quantity signals of these enclosed X axis and Y axis direction and the working position of a manipulator 46 is corrected from these dislocating quantity. Accordingly, the dislocating quantity to the X axis and Y axis directions can be exactly and easily calculated with simple constitution. Further, since working data are corrected, the automatically guided vehicle is not moved again for the position correction after the stop and the manipulator 46 is not moved, either. Thus, the work of loading and unloading can be started just after the stop of the automatically guided vehicle 20.
