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.

Claim (Index 12):
The image reading apparatus according to  claim 1 , further comprising a guide portion that guides reciprocation of the scanning unit; wherein\n the pull member is arranged on a front side compared with the guide portion, and the lock pawl is arranged in a position on a side of the tension acting direction with respect to the axial center of the pulley axis and on a front side with respect to the axial center of the pulley axis among positions in the circumferential direction of the following pulley.
