    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.

    Abstract: An image forming apparatus includes an image reading unit, an image forming unit, a discharge unit, and a discharge tray. The image reading unit is configured to read a document placed on a document placement table by moving and scanning of a scanning body in a sub-scanning direction. The image forming unit is configured to form an image read by the image reading unit on a paper sheet. The discharge unit is configured to discharge the paper sheet on which an image is formed by the image forming unit to a direction perpendicular to the sub-scanning direction. The discharge tray is on which the paper sheet from the discharge unit is to be placed with a space portion at a lower side of the image reading unit. A bottom surface of a housing of the image reading unit facing the discharge tray is constituted of a first surface and a second surface. The first surface is a surface at a front side of the discharge unit in a discharging direction and high with respect to the discharge tray. The second surface is a surface at a back side of the discharge unit in the discharging direction lower than the first surface with respect to the discharge tray. A pulling member and/or a movable wiring are/is arranged at an upper side of the second surface inside the housing. The pulling member is configured to move the scanning body back and forth in the sub-scanning direction. One end portion of the movable wiring is secured to the scanning body.
