A light source device for image reading and scanning, comprising an infrared light cut filter provided between the light emitting rod and the light source lamp to remove an infrared light component from the light emitted from the light source lamp. (2) The light source lamp is made up of a lamp element and a bowl-shaped reflector, and the light emitting rod is housed in a cylinder having an opening slit in the length direction of the circumference, and the reflector of the light source lamp and the light emitting rod are 2. The light source for an image reading device according to claim 1, wherein the cylindrical body of the emitting rod is coaxially connected via a condenser having a substantially conical shape, and an infrared light cut filter is fixed inside the condenser. Device. (3) An image reading section below the image reading platen and a lamp moving section arranged in parallel with the image reading section are defined inside the image reading scanning device, and the light emitting rod is positioned in the image reading section. 3. The light source device according to claim 1, wherein the light source lamp is located in the lamp moving section. (4) This claim is applicable only to an image reading device with a reduction optical system that uses lenses in which the diffusion stripes provided on the light emitting rod are formed to gradually become wider toward both longitudinal ends of the rod. The light source device according to claim 1 or 2. (For density sensors such as Epson (same-magnification optical system), uniform light is better.
