Abstract:
An image reading apparatus includes an illumination unit that illuminates light on an image surface of a sheet, and a photoelectric conversion element that converts reflected light from the sheet illuminated by the illumination unit into an electric signal. The illumination unit includes a circuit board including a light emitting element, and a light guide that guides light, emitted from the light emitting element, to a sheet read surface. In the image reading apparatus, the light guide includes a positioning surface that abuts against a first surface of the circuit board and that performs positioning of the light guide and the circuit board, and a pressing portion that abuts against a second surface of the circuit board on an opposite side of the first surface and that presses the circuit board against the positioning surface.

Claim (Index 1):
An image reading apparatus comprising:\n an illumination unit configured to illuminate light on an image surface of a sheet; and an image reading device configured to read an image on the sheet, wherein the illumination unit includes\n a circuit board on which a plurality of light emitting elements is aligned, and \n a light guide that guides light, emitted from the plurality of the light emitting elements, to a sheet, the light guide including a first surface facing a surface of the circuit board intersecting an array direction in which the plurality of the light emitting elements is aligned.
