    Abstract: An optical reading apparatus and a multifunction-type image forming apparatus, with a minimized thickness in a cabinet height direction and a housing shaped along an upper shape of discharge tray of the image forming apparatus provided thereunder. The optical reading apparatus comprises: platen glass defined with one end and the other end, on an upper surface of which an original document is placed; an optical reading unit that translates between the both ends on a lower surface of the platen glass, for obtaining image data by irradiating an original document surface with light through the platen glass; a control circuit board connected to the optical reading unit, for processing an electric signal; and a housing wherein a side on the side of the other end is thicker than a side on the side of the one end. The image forming apparatus has a cabinet containing: sheet discharge unit for discharging an image formation sheet from a lower-part lower-side on the thicker side of the housing of the optical reading apparatus toward a lower-part upper side on the thinner side of the housing; and a discharge tray on which the image formation sheet discharged from the sheet discharge unit is received and stacked.

    Abstract: To provide an illumination device in which there is no variation in light intensity distribution of the illumination device, and in which illumination spots, particularly light intensity spots, are not prone to occur in a read image in an image reading device, by maintaining a constant gap between a light source and an end face of a light guide. The illumination device includes: a light guide having an end face for taking in light, a diffuse reflecting surface for diffusely reflecting the light taken in from the end face, and a light exit surface for emitting the light that is diffusely reflected at the diffuse reflecting surface towards an irradiation surface. The illumination device further include a reflector having a diffuse reflecting surface that reflects light from the light source toward the one end face of the light guide. The light guide has, at the one end, a flange portion that abuts the reflector, the light source is mounted to a circuit board, and the reflector is held between the flange portion of the light guide and circuit board so as to maintain a predetermined gap between the light source and light guide.
