Disclosed is an inspection machine provided with an imaging device that capture a close-up image of the imaging target portion of the printed circuit board (W) on which a plurality of electronic components (C) are mounted, by coming close to a printed circuit board (W). The inspection machine has a sensor unit (120) that detects the heights of the electronic components (C) on the printed circuit board (W) by irradiation light (Ll, L2) in a first direction that is along the surface of the printed circuit board (W). Control means (600) of the inspection machine sets a limit distance to a position above the highest electronic component (C) among heights detected from the electronic components. The control means (600) also restricts a facing distance by which the imaging device is accepted to approach the printed circuit board (W), to be the limit distance. |
