PROBLEM TO BE SOLVED: To clearly image the appearance of an electronic component and the display formed on the component surface by using one image sensor. SOLUTION: This equipment picks up the images of appearance of an electronic component (a) and the display (d) on the surface, by using an image sensing device 2, while the component (a) is irradiated with illumination lights from luminaires 3, 4. The equipment is provided with first luminaires 3 which cast lights almost perpendicularly to the plane of the component (a), second luminaires 4 which cast lights obliquely to the plane of the component (a), and an image sensing element 2 which picks up the image of the plane with an optical axis almost perpendicular to the plane of the component (a). In the state that the component (a) is irradiated with the illumination lights from the first luminaires 3, the image of appearance of the component (a) can be clearly picked up, and the state of external damage such as chips of the component (a) can be clearly inspected. In the state that the component (a) is irradiated with the illumination lights from the second luminaires 4, the reflection from the surface of the component (a) is restrained, and the image of the display of letters and symbols formed on the surface can be clearly picked up. |
