Abstract: An image reading apparatus has a light source unit for illuminating an object to be illuminated, a reading unit for reading the object illuminated by the light source unit, a reflective unit, having at least a first reflection mirror, for reflecting reading light reflected by the object toward the reading unit, and a first light blocking portion for partially blocking light except the reading light. The first reflection mirror has a reflecting surface for reflecting the reading light, and an end surface substantially orthogonal to the reflecting surface. The first light blocking portion extends in a longitudinal direction of the first reflection mirror toward the end surface of the first reflection mirror, with a tip end of the first light blocking portion being opposed to the end surface of the first reflection mirror with a gap therebetween.

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.
