Abstract
A positioning unit includes two or more the laser light sources disposed around a point sensor. Laser light beams from the two or more the laser light sources intersect at an adjustment point separated from a detection point, which is away from the point sensor, by a predetermined distance. The adjustment point is positioned on a desired measurement start point on a work, the point sensor is moved close to the work by the predetermined distance, and a measurement scan of the work is started.
