Abstract: A sheet transfer apparatus for transferring a sheet is provided with a back receiver section that rotates a sheet to transfer, and a support section that supports the back face of the back receiver section swingably. By this means, the back receiver section is capable of rotating smoothly.

Abstract: A sheet bundle discharging apparatus, including: a guide unit configured to guide a sheet bundle with a spine as a leading end; a receiving unit configured to receive the spine of the sheet bundle guided by the guide unit; and a discharging unit configured to discharge the sheet bundle, wherein the receiving unit includes: a first surface configured to receive the spine at a first position; a second surface configured to push the sheet bundle in a rotation direction of the receiving unit; and a third surface configured to regulate a movement of the sheet bundle in the rotation direction while the receiving unit rotates from the first position to a second position, and wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface is larger than a friction coefficient between the first surface and the sheet bundle.

Abstract: First and second detecting members that detect a sheet or an object lifted beyond a delivery position at which the sheet is delivered is provided, and the second detecting member is configured to be activated in conjunction with activation of the first detecting member. Thus, with a simple configuration, it is possible to detect, over a wide area above a sheet loading section, a sheet or an object placed at a wrong position.
