PURPOSE:To provide a titled device which does not degrade the light emission efficiency of a light source, is compact and is light in weight by constructing a reflection shade of a light source for exposure in such a way that it can be divided vertically with the non-reflection surface part thereof as a center. CONSTITUTION:Part of a frame body 11 for the entire part of an illuminating device is constituted as a reflection shade 10, and the reflection surface 10A of the shade 10 is formed of elliptical curves. A light source lamp 3 for exposure is provided in the position where the light thereof can be reflected concentrically by the surface 10A. The shade 10 is so constituted that the surface 10A of elliptical curves on the inside surface is bisected equally and that the bisected parts are connected and fixed to one body by means of a connecting screw 13 in the non-reflection surface 10B part, whereby the exposure of an original 1 is made efficient by the 2nd reflection surface 14 of a flat surface. The 1st reflection mirror 4 is formed in the same body 11, and, for example, in the case of polishing the inside surface of the shade 10, the screw 13 is loosened and the shade 10 is divided vertically, whereby the easy job is made possible. |
