Abstract

PURPOSE:To accurately detect the mounting position of a part to be mounted to a surface by using such illuminating means as to image the profile portion of a part mounted to a substrate in high brightness as compared with the other portion and detecting the position of the highly bright portion. CONSTITUTION:A parallel light beam is projected on a substrate with an inclination and the illumination of the light beam is restricted to a specific direction to the utmost when the substrate is viewed from above. By adopting such an illumination system, only the light beam projected on the edge portion of a chip part 10 is inputted to a TV camera. In result, the output of the TV camera 21 has an image with a high level of brightness only in the portion shown by a thick full line in the accompanying drawing. By detecting the position of the highly bright portion, the mounting position or attitude of the part on the substrate is recognized.
