An electronic circuit part mounting machine capable of accurately inspecting a part mounting accuracy, wherein a large number of parts (20) are mounted on the upward part mounting surface of an inspected substrate (300), the inspected substrate (300) is made of a transparent material, a pressure sensitive adhesive double coated tape made of a transparent material is stuck on the part mounting surface, and the parts are pressingly fixed to the adhesive double coated tape, circular marks (302) are formed on a large number of lattice points on the inspected substrate (300) and the parts (20) are mounted on the inspected substrate (300) at predicted mounting positions apart equal distances from four circular marks (302) adjacent to each other, the inspected substrate (300) is inversed upside down and held on a wiring board holding device (18) through an inspection jig (304), and the parts (20) and the circular marks (302) around the periphery thereof are imaged by a reference mark camera (152) from the rear side of the parts through the inspected substrate (300) and the pressure sensitive adhesive double coated tape to detect the mounting positions of the parts (20) based on the relative position of the parts (20) to the circular marks (302). |
