PROBLEM TO BE SOLVED: To obtain a device for reducing part costs, and for simplifying an assembling work and a maintaining work by holding a lamp for illuminating an original by a snap fit part for fixing the lamp. SOLUTION: A light source fixing part 11 is constituted by forming a cylindrical ring part 14 at the edge part of a supporting plate 13 projected from a plane plate 12. This light source fixing part 11 is formed of resin materials. Also, a snap fit part for holding a lamp is constituted of the supporting plate 13 and the ring part 14. The plane plate 12 of the light source fixing part 11 is allowed to function for fixing the light source fixing part 11 to an optical frame, and also as a reflector for reflecting a light from the lamp. The supporting plate 13 of the snap fit part is projected almost vertically from a reflecting surface 12b of the plate 12 so that the ring part 14 formed at the end part can be supported. Also, the ring part 14 of the snap fit part is formed like a cylinder with an inside hollow so that the lamp can be held inside. |
