Original Abstract Submitted

A sheet stacking apparatus includes a stacking unit, a regulating member, and a detection device. The stacking unit has a stacking surface on which sheets to be fed in a sheet-feeding direction are stacked. The regulating member is movable in the sheet-feeding direction and configured to regulate the sheet by coming into contact with an upstream edge of the sheet in the sheet-feeding direction on the stacking surface. The detection device is configured to detect a size of the sheet on the stacking surface. The detection device includes a rotatable member configured to rotate about an axis in response to movement of the regulating member, the axis extending parallel to the sheet-feeding direction as viewed from above and being positioned below the stacking surface. The detection device also includes a sensor configured to detect a position of the rotatable member.
