Abstract
An electronic component mounting apparatus (1) includes a device for illuminating a mark (9) on a printed circuit board (14) for recognition. The illumination device (10) includes a light path adjustable member (5). This light path adjustable member (5) is disposed between an illumination source unit (2) and the object (9) to be illuminated. At least one of the light incidence side and the emission side of the light path adjustable member (5) is divided into a plurality of subareas (6), (7), (8), each having a different index of refraction. Each of the subareas (6), (7), (8) emits light at a respective different index of refraction. The emitted light can be collected on a specific area containing the object (9), and appropriate illumination light can thus be emitted to the object (9).
