    Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device which gives high image quality and is easy in adjustment of optical axis. SOLUTION: The optical axis of the optical scanning device 10 is adjusted by moving a circuit substrate 32 on which an open light emitting element type semiconductor laser 14 is mounted along the base plane 30A of an optical box 30. Thus, the optical axis is easily adjusted. Further, the circuit substrate 32 is fitted to the base plane 30A of the optical box 30 and an optical scanning giving a high image quality is available by suppressing the influence of the thermal deformation of the optical box. Further, the semiconductor laser 14 is arranged in the optical box which is nearly sealed with a cover, and the attachment of dust and a dielectric breakdown are prevented even the open light emitting element type is used, thus the deterioration of the image quality is prevented.

    Abstract: PROBLEM TO BE SOLVED: To provide an image reading apparatus in which heat generated from a photoelectric conversion element can be dissipated appropriately while suppressing incidence of disturbance light or mixing of dust to a space between a lens and the photoelectric conversion element, and work cost required for manufacturing can be reduced.SOLUTION: A light condensation member 10 includes a barrel 11 which shields the space between a lens 1 and a photoelectric conversion element 4a from the outside. The barrel 11 consists of a member 11a where the incidence side of the lens 1 is formed into substantially cylindrical shape, and a member 11b where the exit side of the lens 1 has a square shape opening wider than the outer shape of the photoelectric conversion element 4a, with both members molded integrally of resin, and is disposed to cover the photoelectric conversion element 4a with its square enclosure. Out of the square enclosure, both side faces facing each other in the longitudinal direction have concave shape 1b so that a gap is formed between a substrate to which the photoelectric conversion element 4a is fixed.
