1. A sheet bundle discharging apparatus configured to discharge a sheet bundle including a spine, the sheet bundle discharging apparatus comprising:
a conveyance unit configured to convey the sheet bundle;
a guide unit configured to guide the sheet bundle conveyed by the conveyance unit so that the spine is located at 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 to an outside of the sheet bundle discharging apparatus,
wherein the receiving unit is rotatable between a first position and a second position,
wherein the receiving unit receives the spine at the first position,
wherein the receiving unit rotates from the first position to the second position to place the sheet bundle on the discharging unit,
wherein the receiving unit includes:
a first surface against which the spine abuts when the receiving unit receives the spine at the first position;
a second surface on which the sheet bundle is slidable before the spine abuts against the first surface, the second surface being configured to push the sheet bundle in a rotation direction of the receiving unit while the receiving unit rotates from the first position to the second position; and
a third surface which is arranged so as to be opposed to the second surface, the third surface being configured to regulate a movement of the sheet bundle in the rotation direction of the receiving unit while the receiving unit rotates from the first position to the second position, and
wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface on the third surface is larger than a friction coefficient between the first surface and the sheet bundle.
