<p><P>PROBLEM TO BE SOLVED: To solve the problem that dimensions and a shape could not be controlled by the conventional proximity type distance sensor since a hot H-steel is greatly bent and warped. <P>SOLUTION: The H-steel 70 is measured by four light wave range finders 40, 41, 42, and 43. For that purpose, a frame 25 is set to be a rectangular frame to improve the installation property of the light wave range finders 40, 41, 42, and 43. As a result, the light wave range finder can set the distance to an inspection target to a fully large value, flexibly copes with a change in distance, and is fully compact. By converting distance information to dimension/ shape information by a signal conversion section, the dimension and shape in the H-shape can be measured and displayed on a display. Since the light wave range finder is used, the hot dimension/shape measuring apparatus of the H-steel can be easily miniaturized. <P>COPYRIGHT: (C)2004,JPO</p> |
