Abstract: A image reading apparatus includes a plurality of point light sources, arranged in a straight line state, configured to output light for lighting a document situated on a contact glass from a lower side of the contact glass, a light leading member, positioned in front in a light outputting direction of the light output from the point light sources, configured to lead the light output from the point light sources so as to irradiate along a main scanning direction toward the document situated on the contact glass, and a photoelectric conversion element configured to receive reflection light from the document. The light leading member includes positioning means configured to make a gap between each of the point light sources arranged in a line state and the light leading member constant and make an arrangement direction of the point light sources be positioned along a longitudinal direction of the light leading member.

Abstract: An optical component mounting device and method is disclosed where the optical components are disposed within a thin-walled tube and the tube is configured to produce an interference fit within the cylindrical opening of a mounting sleeve. The optical components are secured to the tube such that their optical axes coincide with the tube longitudinal axis. Mating of the optical mounting assembly to external reference surfaces precisely locates and aligns the optical axes with respect to an external reference axis. The optical mounting assembly provides at least two degrees of freedom to the optical components for facilitating alignment.

Abstract: An exposure device includes a first light emitting element substrate including a plurality of first light emitting elements arranged at an arrangement interval T in a longitudinal direction, and a second light emitting element substrate including a part in the longitudinal direction that overlaps with a part of the first light receiving element substrate so as to form an overlapping region. The first and second light emitting element substrates are shifted from each other in a direction perpendicular to the longitudinal direction. The second light emitting element substrate includes a plurality of second light emitting elements arranged in the longitudinal direction. The second light emitting elements are arranged at the arrangement interval T at least outside the overlapping region. When an interval between two of the second light emitting elements of the second light emitting element substrate disposed in the overlapping region is expressed as a specified interval TS, the specified interval TS and the arrangement interval T satisfy: T≤TS≤2T.
