A component mounting machine is provided with a part camera in which a suction nozzle for sucking a component P and a fiducial mark are provided on a head, a sub-lens is installed in a visual field of a lens, the component P is imaged through a main lens (a main lens portion), and it is possible to image the fiducial mark through the lens and the sub-lens (a sub-lens portion). A calibration plate CP1 is imaged in the main lens portion, distortion correction values of the main lens portion are measured from an obtained image, a calibration plate CP2 is imaged in the sub-lens portion, distortion correction values of the sub-lens portion are measured from an obtained image, and the distortion correction values are stored in advance as a distortion correction table. During component mounting, when the component P which is sucked by the suction nozzle and the fiducial mark are imaged at the same time by the part camera, the obtained image is corrected using the distortion correction table, and a suction state of the component P is detected based on the corrected image. |
