Abstract
An image reader used as a back surface reading unit includes LEDs, a first mirror, a second mirror, a third mirror, a lens, and a CCD inside a housing. The first mirror, which first reflects light reflected from the document, is positioned farther away from the document reading position than other reflecting mirrors (i.e. the second mirror and the third mirror) in an optical axis direction of the optical path connecting the document reading position and the first mirror.
