Abstract: A driving device is used in an image reading apparatus, and reciprocates a scanning unit for reading an image on an original. The driving device comprises a pull member, a driving pulley which transmits driving force to the pull member, a following pulley which applies tension to the pull member and a pulley holder having a pulley axis which holds the following pulley rotatably. Then, the pulley axis has a lock pawl capable of locking an upper end portion of the following pulley and canceling engagement with the following pulley by being tilted toward a side of an axial center by elastic deformation. Furthermore, the lock pawl is arranged at a side of a tension acting direction from the pull member to the following pulley except the farthest position from the driving pulley among positions in a circumferential direction of the pulley axis. It is possible to attach and detach the following pulley easily at a time of maintenance or the like.

Abstract: An image reading device includes an image reader that scans a document so as to read an image of the document. The image reader includes a scanning body in which at least plural mirrors, a condenser lens, and an image sensor are disposed. In the scanning body, concerning positional relationships among the plural mirrors as viewed from a main scanning direction, the plural mirrors are disposed on two sides with respect to an imaginary line extending along an optical axis of reflected light from the document. The mirrors on a corresponding one of the two sides are disposed such that a reflecting position of a mirror on a downstream side in a traveling direction of the reflected light is positioned closer to the document and also to the imaginary line than that of a mirror on an upstream side in the traveling direction of the reflected light.
