PROBLEM TO BE SOLVED: To provide an electronic component mounting device which can stably recognize an object to be mounted and stably carry out mounting work on the object. SOLUTION: An optical path adjusting member 5, having a light incident surface and a light-emitting surface, at least one of which is divided into small sections having different refractive indexes, is positioned between at object to be irradiated with light and an lighting source section 2 which irradiates the object with the light as an illuminator 10 for recognizing marks on a printed board 14 so as to emit the light made from the lighting source section 2 at different refractive angles. Therefore, the object can be suitably irradiated with the light by condensing the light rays emitted from the member 5 to a prescribed area, including the object. |
