Abstract
A stacking apparatus includes a limiting member which moves along a feeding direction and limits a trailing edge of a stacked sheet in the feeding direction, and a partition member which partitions a space at a height which is lower than a predetermined height, into a first space corresponding to a first stacking unit and a second space corresponding to a second stacking unit in a feeding direction. The partition member includes a first opening portion for communicating the first space and the second space with each other, and a second opening portion that allows the limiting member to move.
Claims10
A stacking apparatus capable of stacking, as a sheet fed to a predetermined apparatus, a first sheet and a second sheet having a larger size than the first sheet in a feeding direction in which the sheet are fed to the predetermined apparatus,
- the stacking apparatus comprising:
- a first stacking unit configured to stack the first sheet;
- a second stacking unit configured to be able to move at a height which is equal to or higher than a predetermined height and stack the second sheet in cooperation with the first stacking unit at a height which is equal to or higher than the predetermined height;
- a limiting unit configured to move along the feeding direction and limit a trailing edge of a stacked sheet in the feeding direction;
- and
- a partition member configured to partition a space at a height which is lower than the predetermined height, into a first space corresponding to the first stacking unit and a second space corresponding to the second stacking unit in the feeding direction,
- wherein the partition member includes a first opening portion for communicating the first space and the second space with each other, and a second opening portion that allows the limiting unit to move.
A feeding apparatus comprising:
- a stacking apparatus capable of stacking, as a sheet fed to a predetermined apparatus, a first sheet and a second sheet having a larger size than the first sheet in a feeding direction in which the sheet are fed to the predetermined apparatus;
- and
- a feeding unit configured to feed a sheet stacked on the stacking apparatus,
- wherein the stacking apparatus includes:
- a first stacking unit configured to stack the first sheet;
- a second stacking unit configured to be able to move at a height which is equal to or higher than a predetermined height and stack the second sheet in cooperation with the first stacking unit at a height which is equal to or higher than the predetermined height;
- a limiting unit configured to move along the feeding direction and limit a trailing edge of a stacked sheet in the feeding direction;
- and
- a partition member configured to partition a space at a height which is lower than the predetermined height, into a first space corresponding to the first stacking unit and a second space corresponding to the second stacking unit in the feeding direction, and
- the partition member includes a first opening portion for communicating the first space and the second space with each other, and a second opening portion that allows the limiting unit to move.
An image forming apparatus comprising:
- a stacking apparatus capable of stacking, as a sheet fed to a predetermined apparatus, a first sheet and a second sheet having a larger size than the first sheet in a feeding direction in which the sheet are fed to the predetermined apparatus;
- a feeding unit configured to feed sheet stacked on the stacking apparatus;
- and
- an image forming unit configured to form an image on the sheet fed by the feeding unit,
- wherein the stacking apparatus includes:
- a first stacking unit configured to stack the first sheet;
- a second stacking unit configured to be able to move at a height which is equal to or higher than a predetermined height and stack the second sheet in cooperation with the first stacking unit at a height which is equal to or higher than the predetermined height;
- a limiting unit configured to move along the feeding direction and limit a trailing edge of a stacked sheet in the feeding direction;
- and
- a partition member configured to partition a space at a height which is lower than the predetermined height, into a first space corresponding to the first stacking unit and a second space corresponding to the second stacking unit in the feeding direction, and
- the partition member includes a first opening portion for communicating the first space and the second space with each other, and a second opening portion that allows the limiting unit to move.
