ABSTRACT:
An image reading unit includes a light source for illuminating a document, a plurality of reflecting devices for reflecting the light from the document, a condensing device for condensing the light reflected by the reflecting devices, and a reading device disposed at a condensing position at a rear side of the condensing device. The light source is disposed at a forward side of the condensing device. A plurality of reflecting devices includes a final reflecting device and a reciprocating reflecting device. The final reflecting device forms a linear optical path together with the reading device, and the reciprocating reflecting device forms at least one reciprocating optical path crossing the linear optical path between the condensing device and the reading device. Accordingly, the image reading unit can be made small.
