Abstract: A sheet transport apparatus is equipped with a sheet transport guide section for guiding a sheet to be transported. The sheet transport guide section includes a first transport guide member swingable about a first axis, and a second transport guide member swingable about a second axis, the second transport guide member forming a sheet transport path between the second transport guide member and the first transport guide member. The second transport guide member is arranged at a first position when the first transport guide member is closed, at a second position where the second transport guide member is opened from the first position when the first transport guide member is opened, or at a third position where the second transport guide member is opened from the second position.

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.
