Abstract
An image reading apparatus for reading an image of a document optically by illuminating a document with light emitted from a plurality of light emitting elements arranged linearly and by reading light reflected from the document. The image reading apparatus has a first light emitting element for emitting light in a first direction, a second light emitting element for emitting light in a second direction and one substrate for supporting the first light emitting element and the second light emitting element thereon.
