A sheet stacking apparatus comprising:
- a sheet stacking portion on which a sheet discharged from a sheet discharge port is stacked;
- a cover portion configured to move to a closed position for covering the sheet discharge port and the sheet stacking portion and an open position for allowing taking out of the sheet stacked on the sheet stacking portion;
- a sheet pressing portion configured to move to a press-down position for pressing the sheet stacked on the sheet stacking portion and an apart position that is distant from the sheet stacked on the sheet stacking portion;
- and
- a movement-linking portion configured to cause the sheet pressing portion to move from the apart position to the press-down position upon an opening movement of the cover portion.
A sheet stacking apparatus comprising:
- a sheet stacking tray on which a sheet discharged from a sheet discharge port is stacked;
- an openable cover member configured to move to a closed position for covering the sheet discharge port and the sheet stacking tray and an open position for allowing taking out of the sheet stacked on the sheet stacking tray;
- a sheet pressing member pivotably supported and configured to move to a first position where the sheet pressing member is apart from the sheet stacking tray and to a second position closer to a stacking surface of the sheet stacking tray;
- an arm portion integral with the sheet pressing member;
- and
- an engaging portion provided on the cover member for engaging with the arm portion to bring the sheet pressing member to the first position when the cover member is at the closed position, and for disengaging from the arm portion to cause the sheet pressing member to press a sheet on the stacking surface of the sheet stacking tray when the cover member is at the open position.
