PURPOSE: To realize an automatic mounting check through a simple lighting equipment, to reduce a product in cost, and to enable the mounting check device concerned to be easily maintained and controlled in quality by a method wherein the image of a board obliquely illuminated is picked up by a camera provided in a vertical direction, and the positional data of component electrodes are measured.
CONSTITUTION: A board 10 is mounted on an X-Y table 20 and positioned so as to enable a check object to be located in the visual field of an image pick-up camera 40. In this case, the camera 40 is installed just above the board 10. The board 10 is obliquely illuminated by an oblique lighting device 30, the board is discriminated from the component electrode in the image data through a lightness difference between them basing on the light scattering characteristic difference between the board 10 and the component electrode, the positional data of the component electrode is measured, and a component is checked in mounting state. By this setup, an automatic mounting check of a component can be realized through a simple lighting equipment, a product can be reduced in cost, and the mounting check device concerned can be easily maintained and controlled in quality.
