ABSTRACT:
The position of a part-mounting section on a circuit board may be displaced from a reference point. It is therefore necessary to detect the actual position of each part-mounting section before an electronic part is mounted on it. Each circuit board has a plurality of part-mounting sections located in close proximity to each other. The positions of a predetermined number of the part-mounting sections are collectively detected continuously, followed by mounting the electronic parts on the part-mounting sections, thereby shortening the time required of the mounting work.
