PURPOSE:To easily execute sufficient destaticizing without making the contour of a destaticizing area unclear even if the reflectance of the inner surface of a lamp house is made high, and the quantity of incident light on a photosensitive body is large by attaching a lens array body including the array of a condenser lens part whose lens surface is housed in an aperture area, in front of the aperture side of the lamp house. CONSTITUTION:The lens array body 6 including the array of the condenser lens part 36a whose lens surfaces are housed in the area of an aperture 33b and composed of the molded piece of the transparent resin such as acrylic, is attached to the front surface of the side of the aperture 33b of the lamp house 33, so as to be in contact with tone front end surfaces of the ceiling and partition wall 33a of the lamp house 33, and the side surface 31a of a circuit substrate 31. The condenser lens part 36a of the lens array body 36, converges direct light from a bear chip LEP 32 so as to obtain parallel light, or focused light. Thus, the light of a light emitting element is converged on the condenser lens part 36a, and made incident on the photosensitive body, so that even if the reflectance of the inner surface of the lamp house 33 is made high, the diffusion of exit light can be lessened. |
