PURPOSE:To obtain a reader reduced the cost of lighting means and practically removed the heat generation of lighting means by using a fluorescent member as the lighting means and emitting the fluorescent member by external light. CONSTITUTION:An original 1 to be read out is arranged so that the surface to be read out is turned downwards, irradiated light from the lighting means is reflected by the reading surface and the reflected light is guided to a photosensor 4 through a lens array 3 and detected. The fluorescent member 2 obtained by kneading a fluorescent substance into transparent resin such as acrylic resin and molding the flourescent resin is used as the lighting means. When external light is made incident to a part 2b, the fluorescent substance in the fluoresent member 2 emits light and the emitted light is transmitted through the fluoresent member 2, reached to an end surface part 2a and irradiated to the lower surface of the original 1 to be read out.
