Abstract
A catch tray for stacking sheets discharged from an apparatus that includes a first sheet-stacking area and a second sheet-stacking area. The tray further includes a first stopper regulation part disposed, within the second sheet-stacking area, on a downstream side of the sheet discharging direction that regulates edges of discharged sheets of a largest size allowed to be stacked on the catch tray and a second stopper regulation part in the first sheet-stacking area that regulates edges of the discharged sheets of a size smaller than the largest size and elastically deforms in the sheet discharging direction when a sheet of the largest size is discharged so as to allow the first stopper regulation part to regulate an edge of the sheet of the largest size.
