Abstract

A sheet storing apparatus includes: a compression section that performs first compression and second compression by applying a pressing force to sheets stored in a bag; and a control section that controls the pressing force.

First claim

The invention claimed is:

1. A sheet storing apparatus for storing sheets in a bag, comprising:
a holding member configured to hold the bag;
a storage mechanism configured to store sheets in the bag held by the holding member;
a stage on which the bag held by the holding member is placed, the stage configured to move in a first direction and in a second direction opposite to the first direction;
a pressing member configured to apply pressing force to the sheets stored in the held bag which is placed on the stage and to move in the first direction in which the pressing member moves from a first position toward the stage and the second direction in which the pressing member moves away from the stage; and
a controller configured to control the apparatus such that the pressing member performs first compression in which the pressing member applies first pressing force to the sheets stored in the held bag and thereafter second compression in which the pressing member applies second pressing force that is smaller than the first pressing force to the sheets stored in the held bag,
wherein
the controller is configured to control the apparatus such that the pressing member performs the first compression when the pressing member moves in the first direction from the first position to a second position toward the stage at a third position and reaches the second position, and thereafter the pressing member performs the second compression while the pressing member moves in the first direction from the second position to a fourth position by a first distance and the stage moves in the first direction from the third position to a fifth position by a second distance that is larger than the first distance.

2. The sheet storing apparatus according to claim 1 , wherein the pressing member is configured to perform third compression between the first compression and the second compression, the third compression in which third pressing force that is smaller than the first pressing force but is larger than the second pressing force is applied to the sheets.

3. The sheet storing apparatus according to claim 1 , wherein the pressing member is configured to perform third compression between the first compression and the second compression, the third compression in which third pressing force that is smaller than the second pressing force is applied to the sheets.

4. The sheet storing apparatus according to claim 1 , wherein the controller is configured to control the apparatus such that the pressing member moves in the second direction from the fourth position to the first position while the stage stops at the fifth position after the second compression is performed.

5. The sheet storing apparatus according to claim 1 , further comprising a position detection sensor configured to detect a position of a predetermined portion of the pressing member and output a first signal when the predetermined portion of the pressing member is located at the fourth position.

6. The sheet storing apparatus according to claim 5 , wherein the position detection sensor is configured to output a second signal when the predetermined portion of the pressing member is located between the first position and the fourth position.

7. The sheet storing apparatus according to claim 6 ,
further comprising a driving mechanism configured to move the pressing member toward and away from the stage,
wherein
the controller is configured to adjust the pressing force by the controller controlling the driving mechanism.

8. The sheet storing apparatus according to claim 6 , wherein the controller is configured to control the apparatus such that the stage and the pressing member move in the first direction until the controller receives the first signal, and after reception of the first signal, the pressing force is reduced until the controller receives the second signal, and after reception of the second signal, the stage and the pressing member move in the first direction maintaining a constant distance between the stage and the pressing member, until the controller receives the first signal again.

9. The sheet storing apparatus according to claim 1 , further comprising an amount detection sensor configured to detect an amount of the sheets stored in the bag, wherein:
the controller is configured to control the apparatus such that the pressing member moves in the first direction while the stage stops at the third position, to apply the pressing force to the sheets, subsequently, the stage and the pressing member move in the first direction by a predetermined distance maintaining a constant distance between the stage and the pressing member, and subsequently, the pressing member moves in the second direction while the stage stops the fifth position when the amount detected by the amount detection sensor is smaller than a predetermined threshold value, and
to control the pressing member so as to perform the first compression and the second compression when the amount detected by the amount detection sensor is equal to or larger than the predetermined threshold value.

10. The sheet storing apparatus according to claim 1 , further comprising a reaction force detection sensor section configured to detect a reaction force applied from the sheets to the pressing member, wherein
the controller is configured to control the pressing force based on the detected reaction force.

11. The sheet storing apparatus according to claim 10 , further comprising a thickness detection sensor section configured to detect a thickness of the sheets stacked in the bag.

12. The sheet storing apparatus according to claim 1 , wherein the first direction is a downward direction and the second direction is an upward direction.

13. The sheet storing apparatus according to claim 1 , wherein
the controller is configured to control the pressing member to the pressing member stops at the fourth position when the pressing member section reaches the fourth position.

14. The sheet storing apparatus according to claim 1 6 , wherein
the controller is configured to control the pressing member such that the pressing member moves in the second direction after the pressing member reaches the fourth position.

15. The sheet storing apparatus according to claim 1 6 , wherein
the controller is configured to control the pressing member and stage such that cause the pressing member reaches the fourth position and stops at the fourth position and the stage stops after the stage moves by the second distance.
