Abstract

A sheet storage apparatus having: a holding section that holds a storage bag for storing a sheet; a first clamping section; and a second clamping section, wherein the first clamping section and the second clamping section relatively approach to clamp the storage bag held by the holding section, and when a direction in which the first clamping section relatively approaches the second clamping section is defined as a first direction, and a direction opposite to the first direction is defined as a second direction, an end of the first clamping section in the first direction is located on a side in the first direction with respect to an end of the second clamping section in the second direction in a state in which the storage bag is clamped between the first clamping section and the second clamping section.

First claim

The invention claimed is:

1. A sheet storage apparatus, comprising:
a feeding section configured to feed a sheet from outside of the sheet storage apparatus into inside of the sheet storage apparatus,
a holding section configured to hold an opening portion of a storage bag for storing the sheet fed into inside of the sheet storage apparatus by the feeding section;
first and second stages configured to be opened and closed, the first and second stages on which a bottom part of the storage bag held by the holding section is placed and between which the storage bag held by the holding section is capable of being disposed; and
first and second clamping sections disposed on the first and second stages, respectively, and between which the storage bag held by the holding section is capable of being disposed, wherein
the first clamping section is configured to and the second clamping section relatively approach the second clamping section in a first direction to clamp the storage bag held by the holding section, and
an end of the first clamping section in the first direction is located on a side in the first direction with respect to an end of the second clamping section in a second direction opposite to the first direction in a state in which the first and second stages are closed.

2. The sheet storage apparatus according to claim 1 , wherein
the first clamping section comprises a plurality of first protrusions spaced apart from each other at a first distance and protruding in the first direction, and
the second clamping section comprises a plurality of second protrusions spaced apart from each other at a second distance and protruding toward a space between the first protrusions adjacent to each other.

3. The sheet storage apparatus according to claim 2 , further comprising a heater configured to heat and seal the storage bag held by the holding section on a lower side of the first clamping section and the second clamping section, wherein
the first distance is at most twice a distance between an upper end of the first clamping section and the heater, and
the second distance is at most twice a distance between an upper end of the second clamping section and the heater.

4. The sheet storage apparatus according to claim 1 , wherein the first clamping section and the second clamping section are configured to approach each other, and be separated from each other by moving in a horizontal direction.

5. The sheet storage apparatus according to claim 1 , wherein the first clamping section and the second clamping section are configured to move in a vertical direction along the storage bag held by the holding section, in a state in which the storage bag held by the holding section is clamped between the first clamping section and the second clamping section.

6. The sheet storage apparatus according to claim 1 , wherein each of the first clamping section and the second clamping section is formed in a flat plate shape extending in a horizontal direction.

7. The sheet storage apparatus according to claim 1 , wherein the first clamping section and or the second clamping section comprises first and second rollers, respectively, which abut the storage bag held by the holding section in a state in which the storage bag held by the holding section is clamped between the first and second clamping sections.

8. The sheet storage apparatus according to claim 7 , wherein the storage bag comprises a side surface provided with a printed section, and each of the first clamping section and the second clamping section including the roller is disposed adjacent to the side surface of the storage bag.

9. The sheet storage apparatus according to claim 1 , wherein the storage bag held by the holding section is clamped between the first clamping section and the second clamping section when the first and second stages are closed.

10. The sheet storage apparatus according to claim 1 , wherein the first clamping section and the second clamping section are disposed on an upper surfaces of the first and second stages, respectively.

11. The sheet storage apparatus according to claim 1 , wherein the first and second stages comprising heating members below the first and second clamping section respectively, the heating member configured to heat-seal the storage bag held by the holding section.
