を形成したことを特徴とする照明装置。 In an illumination device, a large number of light emitting elements are arranged in a straight line on a substrate, the light emitted from the light emitting elements is reflected by a reflector, and the reflected light is focused by a bar lens and irradiated onto the document surface. A lighting device characterized in that a linear positioning portion that engages with the bar lens is formed in the lens mounting portion along the arrangement direction of the light emitting elements.
