Abstract
An image reading apparatus according to an aspect of the invention includes a first reading unit which reads a surface of a document and a second reading unit which reads the other surface of the document. The first and second reading units include off-axial imaging units respectively. The off-axial imaging unit includes plural imaging mirrors in which off-axial reflecting surfaces having curvatures are formed. In the off-axial imaging unit, an incident direction and an outgoing direction of a reference axis light beam are different from each other. The off-axial imaging units are provided such that vertical directions of the first and second reading units become identical while an incident side of the light beam is located below an outgoing side with respect to the imaging unit.
