Claim of US Patent No. 9,079,743

1. A sheet conveying apparatus comprising:
a staying unit disposed in a conveyance path through which a sheet is conveyed, and configured to hold at least one sheet
in staying and feed the sheet held in staying again to the conveyance path to superimpose the sheet on a succeeding sheet,
forming a sheet bundle of the sheet held in staying and the succeeding sheet;

a discharge unit configured to discharge a sheet or a sheet bundle;
a stacking unit configured to stack the sheet or the sheet bundle discharged from the discharge unit; and
a pressure unit configured to press a preceding sheet or sheet bundle stacked on the stacking unit against the stacking unit
when a succeeding sheet bundle of a plurality of sheets is discharged on the preceding sheet or sheet bundle on the stacking
unit,

wherein, in a case where a succeeding sheet bundle of a predetermined number of sheets or more is conveyed from the staying
unit and the succeeding sheet bundle is to be stacked on the preceding sheet or sheet bundle on the stacking unit, the pressure
unit presses the preceding sheet or sheet bundle against the stacking unit, and

wherein, in a case where a succeeding sheet or sheet bundle of less than the predetermined number of sheets is conveyed from
the staying unit and the succeeding sheet or sheet bundle is to be stacked on the preceding sheet or sheet bundle on the stacking
unit, the pressure unit does not press the preceding sheet or sheet bundle against the stacking unit.
