Abstract
In a sheet stacking apparatus, a first notch portion in which a first limiting member is movable and a second notch portion in which a second limiting member is movable are formed in a stacking surface of a stacking unit, and the first and second notch portions are arranged such that a minimum distance between the first notch portion and a center of the stacking unit in the widthwise direction is shorter than a minimum distance between the second notch portion and the center of the stacking unit in the widthwise direction.
Claims10
A stacking apparatus capable of stacking a first sheet as a sheet fed to a predetermined apparatus and a second sheet having a larger size than the first sheet in a feeding direction in which the sheet is fed to the predetermined apparatus, the stacking apparatus comprising:
- a stacking unit configured to include a stacking surface and configured to stack the first sheet and the second sheet on the stacking surface, wherein the stacking surface includes a first stacking area, a second stacking area, and a third stacking area;
- a first limiting unit configured to be movable in a widthwise direction perpendicular to the feeding direction, and configured to limit edges of the first sheet and the second sheet in the widthwise direction;
- and
- a second limiting unit configured to be movable in the widthwise direction, configured to limit the edges of the second sheet in the widthwise direction, and configured to be provided on an upstream side of the first limiting unit with respect to the feeding direction,
- wherein a first notch portion in which the first limiting unit is movable is provided so that the first notch portion is overlapped with the first stacking area with respect to the feeding direction and provided on an outer side of the first stacking unit with respect to the widthwise direction, and a second notch portion in which the second limiting unit is movable is provided so that the second notch portion is overlapped with the second stacking area with respect to the feeding direction and provided on an outer side of the second stacking area with respect to the widthwise direction,
- wherein, with respect to the feeding direction,
- the third stacking area is provided on an upstream side of the first stacking area, and the third stacking area is provided on a downstream side of the second stacking area, and
- the first notch portion is provided on a downstream side of the third stacking area, and the second notch portion is provided on an upstream side of the third stacking area, and
- wherein, with respect to the widthwise direction,
- a minimum distance between the first notch portion and a center of the stacking unit is shorter than a minimum distance between the second notch portion and the center of the stacking unit,
- a minimum distance between the center of the stacking unit and an outer edge of the first stacking area is shorter than a minimum distance between the center of the stacking unit and an outer edge of the second stacking area, and
- a distance between the center of the stacking unit and an outer edge of the third stacking area is longer than the minimum distance between the second notch portion and the center of the stacking unit.
