Abstract
On a measuring head which is mounted on a working end of a robot, there are provided an optical distance measuring device and a mirror which refracts an optical axis of the distance measuring device toward the plate surface of a workpiece. The measuring head is moved such that a point of irradiation of a light beam relative to the workpiece moves along a scanning line which is set so as to cross a hole edge point. The position at which the measured distance rapidly changes is set as the position of the hole edge point of a hole which crosses the scanning line. In case holes are respectively formed in a pair of plate portions which lie opposite to each other, the measuring head is provided with a distance measuring device and a mirror in a pair respectively so that the positions of both the holes on both sides can be measured at the same time.
