ABSTRACT:
An image reading apparatus includes an illuminating optical system having light sources arranged in a line and a light guide member guiding rays of light from the light sources to illuminate a document which passes through a document reading position near a light emergent surface of the light guide member. An image reading optical system includes a rod lens array to read light passing through the document, and a cylindrical lens array in the light emergent surface of the light guide member. Ridge lines running along a subscanning direction on the light guide member are aligned in a scanning direction.
