<p>The invention concerns a method of and a device for detecting the position of a body (W) by which this position can be detected without the necessity of a special detector or a very complicated calculating processing. According to the method, the position is detected by measuring space coordinates of three, two and one points (f1, f2, f3 ; g1, g2 ; h1) respectively on faces (F ; G ; H) of the body which are included in three mutually intersecting planes. The position detecting device comprises a switch means for detecting a predetermined position of the moving body in a first direction, and first and second distance measuring means which operate, in response to the switch means, individually at two different timings to measure distances from known points in directions oblique to the first direction and to each other to three and two points on different obliques faces, respectively. A calculating means calculates the position of the body in accordance with results and timings of the measurements by the first and second distance measuring means and data of a configuration of the body.</p> |
