Abstract

PURPOSE:To measure the width and lateral curvature of a metallic plate easily with high precision by extending metallic wires in parallel on both sides of the metallic plate, and running an optical position detector which engages with them. CONSTITUTION:On a mounting table 2, a metallic plate 1 to be measured is mounted horizontally while both its edge parts project from the mounting table and nearly in parallel to the lengthwise direction of the mounting table. Then, the positions of shores 4 stood upright on a base 3 are adjusted and metallic wires 5 are extended between the shores 4. The metallic wires are tensed by tensing devices 6 and position detectors 7 are engaged with them. Each detector 7 has a light source 7b and a photodetecting element 7a provided successively opposite to each other; and a driver 9 moves a metallic plate 8 for movement and the detectors measure the edge parts continuously.
