Abstract

A printing apparatus includes a conveying unit that conveys a stored sheet to a position where the sheet can be picked up based on received instructions to pick up the stored sheet on which an image is printed. The printing apparatus performs control such that the sheet is not conveyed by the conveying unit while the sheet is being stored in the storage unit.

First claim

What is claimed is:

1. A printing apparatus comprising:
a printing unit configured to print an image on a sheet;
a conveyance path configured to convey the sheet on which the image is printed by the printing unit;
a sheet stacking unit on which the sheet discharged from the conveyance path is stacked inside the printing apparatus;
an extrusion member configured to push an edge of the sheet stacked on the sheet stacking unit such that a part of the stacked sheet is exposed outside the printing apparatus via a discharge port, wherein the extrusion member is reciprocated between a stack position and an extrusion position;
an operation unit configured to input a user instruction for picking up the sheet; and
a control unit configured to control the extrusion member to move from the stack position to the extrusion position in response to the user instruction input by the operation unit,
wherein the control unit controls the movement of the extrusion member from the stack position to the extrusion position to be restricted while the printing unit prints an image on a sheet to be stored in the sheet stacking unit.

2. The printing apparatus according to claim 1 ,
wherein the operation unit is configured to display a picking-up key corresponding to the sheet stacking unit for receiving the user instruction, and
wherein the control unit controls the operation unit not to display the picking-up key while the sheet stacking unit prints an image on a sheet to be stacked on the sheet stacking unit.

3. The printing apparatus according to claim 2 , wherein the operation unit displays the picking-up key in response to stacking of one sheet in the sheet stacking unit.

4. The printing apparatus according to claim 2 , wherein the operation unit displays the picking-up key in response to storing of all sheets corresponding to one job in the sheet stacking unit.

5. The printing apparatus according to claim 2 , wherein the operation unit displays the operation key in the inoperable state when the sheets corresponding to other jobs are stored in the storage unit.

6. The printing apparatus according to claim 1 further comprising a sheet removable stacking unit configured to stack a sheet printed with an image printed by the printing unit, wherein a sheet in the sheet removable stacking unit is removable without the user instruction.

7. The printing apparatus according to claim 6 , wherein the printing unit is provided between the sheet removable stacking unit and the sheet stacking unit.

8. The printing apparatus according to claim 6 , wherein the sheet removable stacking unit and the sheet stacking unit are provided at upper portion of the printing unit.

9. The printing apparatus according to claim 1 , further comprising a receiving unit configured to receive a printing job,
wherein the control unit analyzes the printing job received by the receiving unit and determines whether to discharge a sheet to be printed by the printing unit to the sheet stacking unit.

10. The printing apparatus according to claim 1 ,
wherein the extrusion member comprises a sheet trailing-edge extrusion claw, and
wherein the stack position is a position where the sheet discharged from the conveyance path and the sheet trailing-edge extrusion claw do not interfere with each other.

11. The printing apparatus according to claim 10 , wherein the extrusion position is a position where the sheet discharged from the conveyance path interferes with the sheet trailing-edge extrusion claw.

12. The printing apparatus according to claim 1 further comprising:
a detecting unit configured to detect that a sheet is removed from the discharge port,
wherein the control unit causes the extrusion member to move from the extrusion position to the stack position based on the detection result acquired by the detecting unit.

13. The printing apparatus according to claim 1 , wherein, in a case where the user instruction is input from the operation unit, the control unit determines whether the printing unit is printing an image on a sheet to be stored to the sheet stacking unit, and when it is determined that the printing unit is printing an image on the sheet, the control unit displays a warning message to the operation unit and restricts a movement of the extrusion member from the stack position to the extrusion position.

14. The printing apparatus according to claim 13 , wherein the warning message is a message to inform that a sheet stacking unit selected by a user is currently used for printing process.

15. The printing apparatus according to claim 13 , wherein the warning message is a message to inform a necessity to wait until a printing process to complete.
