The relative position in the horizontal plane is corrected and the position of the guide rail in the horizontal plane with respect to the reference line is determined. On the other hand, based on the seam position signal from the seam position detection means, the vertical position corresponding to the position measured in each of the horizontal planes described above is calculated. Since information regarding the vertical position and the amount of displacement of each measurement point with respect to the reference line are displayed, it is possible to easily recognize where the amount of displacement of each measurement point is located on the guide rail. In addition, since the displacement of the guide rail in the horizontal plane is detected via the rollers, the roughness of the guide surface of the guide rail,
The detection signal is not disturbed due to the difference in level at the seam and the traces of correction of the level difference, allowing for highly accurate detection.
