    • An illumination device for an image input device includes a cylindrical light guiding unit, a board having a plurality of light emitting diode elements, a connection member connecting the light guiding unit with the board and a terminal reflection member formed at one end of the light guiding unit. A surface of the light guiding unit has a scattering reflection member extending linearly along the axial direction of the light guiding unit. A cylindrical reflection member is spaced around the light guiding unit and a linear space is provided in the reflection member along the axial direction of the guiding unit.
