Abstract
A discharged sheet is conveyed, by a sheet conveying portion movable above sheet stacking portions while supporting a sheet, to selected one among plural sheet stacking portions. When the sheet is conveyed to the selected sheet stacking portion by the sheet conveying portion, a member for preventing a bringing-together provided in the main body of the apparatus prevents a sheet bundle, stacked in a sheet stacking portion at the upstream side of the selected sheet stacking portion, from being brought together by the sheet conveyed above the upstream sheet stacking portion by the sheet conveying portion.

A sheet stacking apparatus comprising:
- a plural of sheet stacking portions which stack sheets;
- a sheet conveying portion which conveys a sheet to either one of said plural of sheet stacking portions;
- and
- a guide member disposed above a first sheet stacking portion and which guides a sheet conveyed by the sheet conveying portion to a second sheet stacking portion on a downstream side of the first sheet stacking portion in a sheet conveying direction in which the sheet conveying portion conveys a sheet,
- wherein the guide member is disposed to extent from an upstream end, toward a downstream side in the sheet conveying direction, of the first sheet stacking portion.
A sheet stacking apparatus comprising:
- plural sheet stacking portions which stack sheets;
- a sheet conveying portion which conveys a sheet to either one of the plural sheet stacking portions;
- and
- a guide member disposed above a first sheet stacking portion to guide a sheet conveyed by the sheet conveying portion to a second sheet stacking portion on a downstream side of the first sheet stacking portion in the sheet conveying direction in which the sheet conveying portion conveys a sheet,
- wherein the guide member is provided on a plane, perpendicular to the sheet conveying direction, of a frame member of a main body of the apparatus.
