PURPOSE: To perform proper detection of a component attraction state even in the case of allowing a selective use of a luminous detection means and an imaging means and in the case of using either means. CONSTITUTION: While arranging a laser unit 31 detecting a projection of components on a head unit 5, the main mounting unit is provided with a component recognition camera 33 picking up images of components, besides a control means is provided so as to control a selective use of the laser unit 31 and the components recognition camera 33 according to the kinds of components. Then, this control means detects a component attraction states in a state of attracted component positioned in a prescribed height in accordance with a light beam irradiation position on the basis of projection detection by the laser unit 31 at the time of using the laser unit 31 and at the time of using the component recognition camera 33, the component attraction state is detected in the state of a position at a prescribed height and basing on a pick-up image by the camera 33. |
