PURPOSE:To distinctly detect a working line and to improve the reliability of a follow-up system by forming an opaque paint layer which has a high matte effect to the required part of a work surface and drawing the working line with paint having the lightness different from the lightness of the paint layer on said surface and operating a working apparatus by following up to the working line. CONSTITUTION:An opaque 1st paint layer P1 is uniformly formed by spraying, etc., on the required part of the work W surface. The translucent 2nd paint layer P2 which has the high matte effect is then uniformly formed similarly by spraying, etc., on the 1st paint layer P1. The working line C is drawn on the surface of this paint layer P by using the paint for the working line having the lightness largely different from the lightness of the paint layer P. This working line C is drawn by using a writing means or drawing pen, etc., by which the teaching of the follow-up route to be executed under detection by an ITV camera is executed with high accuracy. Blue lacquer is used as the 1st paint layer P1, fluorescent orange acryl lacquer as the 2nd paint layer P2 and white water ink as the paint for the working line. |
