Abstract

A sheet storing apparatus, includes: an inlet section configured to take in sheets from outside of the apparatus into the apparatus; a storing unit configured to mount a storage bag in a storing area of the storage unit; and a recognition unit configured to count the number of sheets to be stored in the storage bag mounted in the storing area of the storing unit, in which the storing unit includes: a holding section configured to hold the storage bag mounted in the storing area of the storing unit; a support section configured to support the sheets stored in the storage bag from below via the storage bag; a drive section configured to move up and down the support section between an initial position and a final position; and a control section configured to control the drive section, based on the number of sheets counted by the recognition unit.

First claim

The invention claimed is:

1. A sheet storing apparatus for storing sheets into a storage bag having an opening, the sheet storing apparatus comprising:
an inlet through which sheets are taken in from outside of the apparatus into the apparatus;
a transport unit configured to transport the sheets taken into the apparatus through the inlet;
a storing unit which is connected to the transport unit and configured to mount the storage bag in the storing unit, and store, in the mounted storage bag, the sheets transported by the transport unit;
a counter which is disposed at the transport unit and configured to count a number of the transported sheets to be stored in the storage bag mounted in the storing unit;
a holding member which is disposed in the storing unit and configured to hold an upper part, near the opening, of the storage bag mounted in the storing unit;
a first heater which is configured to heat seal a lower part of the storage bag held by the holding member;
a stage which is disposed below the holding member in the storing unit, the stage being provided with the first heater and configured to support the sheets stored in the storage bag from below via the storage bag and to move up and down between a first position and a second position, the first position being a position where the stage is located when the storing unit completes storing the transported sheets in the storage bag, the second position being a position below the first position and where the stage is located when the first heater heat seals the lower part of the storage bag storing the sheets therein;
a controller configured to control the sheet storing apparatus,
wherein when the controller determines that the number of counted sheets is less than a predetermined number, the controller stops moving the stage at one or more times after the stage starts moving down from the first position and before the stage reaches the second position, and
wherein when the controller determines that the number of the counted sheets is the predetermined number or more, the controller moves the stage down from the first position to the second position without stopping the moving of the stage.

2. The sheet storing apparatus according to claim 1 ,
wherein the controller is configured to, in a case where the number of the counted sheets is less than the predetermined number, stop moving the stage a greater number of times than a number of times in a case where the number of the counted sheets is the predetermined number or more.

3. The sheet storing apparatus according to claim 1 ,
wherein when the number of the counted sheets is less than the predetermined number, the controller is configured to reduce a movement speed of the stage compared to a case where the number of the counted sheets is the predetermined number or more.

4. The sheet storing apparatus according to claim 1 , further comprising:
a pusher disposed in the storing unit, the pusher configured to move up and down and configured to press the sheets stored in the storage bag,
wherein the controller controls the movement of the pusher, based on the number of the counted sheets.

5. The sheet storing apparatus according to claim 4 ,
wherein when the number of the counted sheets is less than the predetermined number, the controller controls the sheet storing apparatus such that the pusher and the stage clamp the sheets stored in the storage bag and the stage moves down while the sheets are clamped by the pusher and the stage.

6. The sheet storing apparatus according to claim 4 ,
wherein the controller is configured to control the sheet storing apparatus such that the stage and the pusher move down alternately.

7. The sheet storing apparatus according to claim 4 ,
wherein the holding member includes a first holding member and a second holding member, the first and the second holding members being configured to hold the upper part of the storage bag,
the stage includes a first stage and a second stage, the first and the second stages being configured to clamp the lower part of the storage bag held by the holding member,
wherein the controller is configured to control the sheet storing apparatus such that the first and the second stages have a predetermined gap between the first and the second stages so as to be movable down, and narrow the gap before narrowing a gap between the first and the second holding members.

8. The sheet storing apparatus according to claim 1 ,
wherein the holding member is provided with a second heater configured to heat seal the opening of the storage bag held by the holding member, and
the controller is configured to control the sheet storing apparatus such that after the first heater heat seals the lower part of the storage bag storing the sheets therein, the second heater heat seals the opening of the storage bag storing the sheets therein.

9. The sheet storing apparatus according to claim 1 ,
wherein the storing unit completes storing the sheets in the storage bag before the stage starts moving down from the first position, and
the storing unit does not store the sheets in the storage bag after the stage starts moving down from the first position.
