<p>The present invention repeats in this order: a first imaging operation wherein, during the relative passage of a plurality of nozzles (12) in two rows in a mounting head (14) above a camera unit (20) in the longitudinal direction of the nozzle rows, a camera (24) in the camera unit (20) images a lower view image of a component (P) held on a nozzle of one nozzle row and passing through a first imaging position (Sb1) in a first imaging region of the camera (24); a second imaging operation wherein the camera (24) in the camera unit (20) images a lower view image of the component (P) held on a nozzle of the other nozzle row and passing through a second imaging position (Sb2) in the first imaging region of the camera (24); and a third imaging operation wherein the camera (24) in the camera unit (20) images a side view image of the component (P) held on a nozzle of the other nozzle row and passing through a third imaging position (Ss1) in a second imaging region of the camera (24) and at the same time images a side view image of the component (P) held on a nozzle of the other nozzle row and passing through a fourth imaging position (Ss2) in a third imaging region of the camera (24).</p> |
