Abstract:
A first detection unit detects that a first stacking unit is positioned in a predetermined position and a second detection unit detects that a second stacking unit is positioned in a predetermined position. An upper surface detection unit detects one of a sheet stacked on the first stacking unit and an upper surface of the first stacking unit. It is determined that an error has occurred, when the sheet of the second size is set to be stacked, when the upper surface detection unit has detected a sheet stacked on the first stacking unit, and when the first stacking unit is not in the predetermined position and the second stacking unit is in the predetermined position.

Claim (Index 1):
A stacking apparatus comprising:\n a first stacking unit configured to vertically move between an upper-limit position of upward movement and a lower-limit position of downward movement, and stack a sheet having a first size; a second stacking unit configured to be coupled with the first stacking unit in a predetermined position in a vertical movement direction of the first stacking unit, vertically move together with the first stacking unit while being coupled with the first stacking unit and stack a sheet having a second size larger than the first size by cooperating with the first stacking unit when the position of the first stacking unit is not lower than the predetermined position and not higher than the upper-limit position, and be decoupled from the first stacking unit when the position of the first stacking unit is lower than the predetermined position and not lower than the lower-limit position; a first detection unit configured to detect that the first stacking unit is positioned in the predetermined position; a second detection unit configured to detect that the second stacking unit is positioned in the predetermined position; an upper surface detection unit configured to detect one of a sheet stacked on the first stacking unit and an upper surface of the first stacking unit; a setting unit configured to set a size of a sheet to be stacked from sheets having a plurality of sizes including a sheet of the first size and a sheet of the second size; and a determination unit configured to determine that an error has occurred, when the sheet of the second size is set to be stacked by the setting unit, when the upper surface detection unit has detected a sheet stacked on the first stacking unit, and when the first stacking unit is not in the predetermined position and the second stacking unit is in the predetermined position.
