Abstract

Provided is a medium stacking apparatus, which comprises a stacking frame and a damper. The stacking frame forms a stacking space in which media are stacked, and comprises a medium inlet. The damper collides with the medium introduced through the medium inlet, and absorbs a shock from the medium. The damper comprises one or more damping ribs that extend in a stacking direction of the media and are elastically deformed by a collision with the medium.

Claims

1. A medium stacking apparatus comprising:

a stacking frame forming a stacking space in which media are stacked, and comprising a medium inlet; and

a damper colliding with the medium introduced through the medium inlet, and absorbing a shock from the medium,

wherein the damper comprises one or more damping ribs that extend in a stacking direction of the media and are elastically deformed by a collision with the medium, a damper plate provided at a rear side of the one or more damping ribs to support the one or more damping ribs, and a plurality of guide protrusions disposed on a surface of the damper plate,

wherein the damper plate facing the medium inlet is elastically attached to a surface of the stacking frame by an elastic spring,

wherein each of the one or more damping ribs comprises a first rib fixed to the damper plate, a plurality of connecting ribs connected to the first rib and vertically spaced apart from each other, and a second rib connected to the connecting ribs,

wherein the plurality of guide protrusions are disposed vertically spaced apart from each other such that the medium is inhibited from downward sliding, and

wherein the first rib, the plurality of connecting ribs and the second rib are integrally formed with each other.

2. The medium stacking apparatus of claim 1, wherein the one or more damping ribs are spaced apart from a surface of the stacking frame facing the medium inlet.

3. The medium stacking apparatus of claim 1:

wherein the one or more damping ribs are disposed on the surface of the damper plate facing the medium inlet.

4. The medium stacking apparatus of claim 1, wherein the one or more damping ribs are formed of an elastic material.

5. The medium stacking apparatus of claim 1, wherein the media introduced to the stacking space have two different lengths, and

the plurality of connecting ribs has a length corresponding to a difference between the lengths.

6. The medium stacking apparatus of claim 1, wherein a length of each of the plurality of connecting ribs is longer than a protrusion length of each of the plurality of guide protrusions.

7. The medium stacking apparatus of claim 1, wherein the first rib, the second rib and the plurality of connecting ribs define an opening, and the second rib can be deformed by the opening when colliding with the medium.

8. The medium stacking apparatus of claim 1, wherein each connecting rib is extended from the first rib perpendicularly.

9. A financial device comprising:

a transfer passage through which media are transferred; and

a medium stacking apparatus comprising a stacking space in which the media transferred along the transfer passage are stacked,

wherein the medium stacking apparatus comprises;

a transfer roller introducing the medium to the stacking space;

a stacking guide in the stacking space, the medium being placed on the stacking guide; and

a damper colliding with a front end of the medium introduced to the stacking space,

wherein the damper comprises;

a damper plate;

an elastic spring configured to elastically support the damper plate;

one or more damping ribs provided on a first surface of the damper plate and elastically deformed to absorb a shock from the medium colliding with the one or more damping ribs, the damper plate being provided at a rear side of the one or more damping ribs; and

a plurality of guide protrusions provided on the first surface of the damper plate, and disposed vertically spaced apart from each other such that the medium is inhibited from downward sliding,

wherein each of the one or more damping ribs comprises a first rib fixed to the first surface of the damper plate, a plurality of connecting ribs connected to the first rib and vertically spaced apart from each other, and a second rib connected to the connecting ribs, and

wherein the first rib, the plurality of connecting ribs and the second rib are integrally formed with each other.

10. The financial device of claim 9, wherein the media stacked in the stacking space have different lengths, and

a distance between a side of the damping rib and the damper plate corresponds to a difference between the lengths.

11. The financial device of claim 9, further comprising a sheet roller provided to the damper plate, wherein, when a medium having a length smaller than a width of the stacking space is introduced to the stacking space, the one or more damping ribs absorb a shock from the medium, and the sheet roller is configured to hit a rear end of the medium, and

wherein when a medium having a length corresponding to the width of the stacking space is introduced to the stacking space, the one or more damping ribs are configured to collide with the medium, and at least one of the plurality of guide protrusions is configured to collide with the medium, and the sheet roller is configured to hit a rear end of the medium.

12. The financial device of claim 9, wherein the first rib, the second rib and the plurality of connecting ribs define an opening, and the second rib can be deformed by the opening when colliding with the medium.

13. The financial device of claim 9, wherein each connecting rib is extended from the first rib perpendicularly.

14. A medium stacking apparatus comprising:

a stacking frame forming a stacking space in which media are stacked, and comprising a medium inlet; and

a damper colliding with the medium introduced through the medium inlet, and absorbing a shock from the medium,

wherein the damper comprises a damper plate, an elastic spring configured to elastically support the damper plate, one or more damping ribs that extend in a stacking direction of the media and are elastically deformed by a collision with the medium, the damper plate being provided at a rear side of the one or more damping ribs, and a plurality of guide protrusions disposed on a surface of the damper plate,

wherein each of the one or more damping ribs comprises;

a plurality of connecting ribs fixed to the damper plate and vertically spaced apart from each other, and

a collision rib connected to the connecting ribs,

wherein the plurality of guide protrusions are disposed vertically spaced apart from each other such that the medium is inhibited from downward sliding, and the plurality of connecting ribs and the collision rib are integrally formed with each other.

15. The medium stacking apparatus of claim 14, wherein the collision rib and the plurality of connecting ribs define an opening, the collision rib can be deformed by the opening when colliding with the medium.

16. The medium stacking apparatus of claim 14, wherein each connecting rib is extended from the damper plate perpendicularly.
