Abstract:
1. A sheet aligning mechanism that aligns sheets discharged from a sheet discharging unit into a tray, the sheet aligning mechanism comprising: a first width-direction aligning unit arranged near the sheet discharging unit, for aligning end faces of the sheets in a sheet width direction perpendicular to a sheet discharge direction; a second width-direction aligning unit arranged downstream of the first width-direction aligning unit in the sheet discharge direction, wherein each of the first width-direction aligning unit and the second width-direction aligning unit includes a pair of aligning members and each of the first width-direction aligning unit and the second width-direction aligning unit includes an upward receding mechanism that causes one of the aligning members to upwardly recede from a sheet-alignment operating position; and a drive unit that moves the aligning members of the first width-direction aligning unit and the second width-direction aligning unit in the sheet width direction and drives the upward receding mechanism to cause the aligning members of the second width-direction aligning unit to upwardly recede, wherein the upward receding mechanism of the second width-direction aligning unit includes
