Abstract
Even when descending of a sheet stacking unit is interrupted by an obstacle, sheet stacking operation is resumed in a range in which the sheet stacking unit is movable.
Claims9
A sheet stacking apparatus comprising:
- a descending control unit capable of causing a sheet stacking unit to descend to a lower limit position according to a stacked-sheet amount;
- a determination unit configured to determine that descending of the sheet stacking unit controlled by the descending control unit is interrupted at a first position different from the lower limit position;
- and
- a control unit configured to perform control for stopping sheet stacking on the sheet stacking unit at the first position where the descending of the sheet stacking unit is determined by the determination unit to be interrupted during the sheet stacking on the sheet stacking unit,
- wherein the control unit performs control for causing the sheet stacking unit to ascend when a sheet stacked on the sheet stacking unit is removed in a state in which the sheet stacking on the sheet stacking unit is stopped at the first position, and performing the sheet stacking on the sheet stacking unit after ascending.

A control method of a sheet stacking apparatus, the method comprising:
- controlling a sheet stacking unit to be capable of descending to a lower limit position according to a stacked-sheet amount;
- determining that descending of the sheet stacking unit is interrupted at a first position different from the lower limit position;
- and
- performing control to stop sheet stacking on the sheet stacking unit at the first position where the descending of the sheet stacking unit is determined to be interrupted during the sheet stacking on the sheet stacking unit,
- wherein the sheet stacking unit is caused to ascend when a sheet stacked on the sheet stacking unit is removed in a state in which the sheet stacking on the sheet stacking unit is stopped at the first position, and the sheet stacking is performed on the sheet stacking unit after the ascending of sheet stacking unit.

A computer readable storage medium storing a program for causing a computer to execute a control method, the method comprising:
- controlling a sheet stacking unit to be capable of descending to a lower limit position according to a stacked-sheet amount;
- determining that descending of the sheet stacking unit is interrupted at a first position different from the lower limit position;
- and
- performing control to stop sheet stacking on the sheet stacking unit at the first position where the descending of the sheet stacking unit is determined to be interrupted during the sheet stacking on the sheet stacking unit,
- wherein the sheet stacking unit is caused to ascend when a sheet stacked on the sheet stacking unit is removed in a state in which the sheet stacking on the sheet stacking unit is stopped at the first position, and the sheet stacking is performed on the sheet stacking unit after the ascending of sheet stacking unit.
