Abstract

Disclosed is a compact bill accumulation device which has a bill accumulation space with decreased depth and does not cause bill accumulation errors. The bill accumulation device (100) is provided with front guides (8) and reverse guides which form a bill accumulation space, and with a bill stopper (6) which, disposed on the front guides (8), stops bills released by a by a feed roller (1), wherein bills stopped by said bill stopper (6) are accumulated on a stage (4). Multiple V-shaped grooves are formed on elongate ribs (18) and disposed along the long direction of the ribs, said grooves extending in the short direction thereof; said ribs (18) are arranged in rows and at prescribed intervals on either side of the front guides (8) so as to be perpendicular to said released bills.

Claims

1. A bill accumulation device, comprising:

a guide member for stopping bills discharged by a conveying means;

a stage, upon which the bills stopped by the guide member are stacked; and

a plurality of elongated shaped ribs each extending in a rib long length direction, and each having a plurality of grooves that extend along a rib short length direction, the ribs, in the rib long length direction, being respectively disposed orthogonal to the bills being discharged, with plural ones of the ribs being disposed in a row at specific intervals from each other on both sides of the guide member, wherein;

each of the ribs has curved portions, and

a bill-receiving face of each of the ribs is positioned at a downstream side from a bill-receiving face of the guide member in a bill discharge direction.

2. The bill accumulation device of claim 1, wherein:

the guide member includes a front guide and a bill stopper, each of the ribs being formed to an external wall to which the front guide is attached, such that the maximum depth of the ribs in the bill discharge direction is shorter than a depth of the front guide in the bill discharge direction, and

the bill-receiving face of each of the ribs is positioned at a downstream side from a bill-receiving face of the bill stopper in the bill discharge direction.

3. The bill accumulation device of claim 2,

wherein:

the grooves on each of the ribs are profiled with an inside curved portion on a front guide side of the groove and an outside curved portion at an opposite side of the groove to the inside curved portion; and

a curvature of the outside curved portion is more gentle than a curvature of the inside curved portion.

4. The bill accumulation device of claim 3,

wherein:

the grooves on each of the ribs are further profiled with a flat portion between the inside curved portion and the outside curved portion; and

each of the ribs is disposed to satisfy a relation of

L≦

(tan θ

×

height H)+(height H/tan θ

), wherein L is a separation from a side face of a first of the ribs on an inside curved portion side to a boundary between the outside curved portion and the flat portion of the rib adjacent to the first rib, H is a height at the groove of the rib from the external wall, and θ

is a maximum skew angle θ

of the bills being discharged.

5. The bill accumulation device of claim 1,

wherein:

the grooves on each of the ribs are profiled with the curved portions including an inside curved portion on a guide member side of the groove and an outside curved portion at an opposite side of the groove to the inside curved portion; and

a curvature of the outside curved portion is more gentle than a curvature of the inside curved portion.

6. The bill accumulation device of claim 5,

wherein:

the grooves on each of the ribs are further profiled with a flat portion between the inside curved portion and the outside curved portion; and

each of the ribs is disposed to satisfy a relation of

L≦

(tan θ

×

height H)+(height H/tan θ

), wherein L is a separation from a side face of a first of the ribs on an inside curved portion side to a boundary between the outside curved portion and the flat portion of the rib adjacent to the first rib, H is a height at the groove of the rib from an external wall, and θ

is a maximum skew angle θ

of the bills being discharged.

7. The bill accumulation device of claim 1, further comprising an external wall to which the ribs are formed, wherein a height of each of the ribs and the specific intervals between the ribs are set such that leading end portions of the bills with a skew do not hit the external wall.

8. The bill accumulation device of claim 1, wherein the guide member includes a front guide and a bill stopper, each of the ribs being formed to an external wall to which the front guide is attached, such that the maximum depth of the ribs in the bill discharge direction is shorter than a depth of the front guide in the bill discharge direction.

9. A bill accumulation device, comprising:

a guide member that stops bills discharged by a conveying means;

a stage, upon which the bills stopped by the guide member are stacked; and

a plurality of elongated shaped ribs respectively disposed on each of outer sides of the guide member,

wherein each of the ribs includes a plurality of grooves, with curved portions being formed inside the grooves.

10. The bill accumulation device of claim 9, wherein each of the plurality of ribs is provided at position deeper than the guide member in a bill discharge direction.

11. The bill accumulation device of claim 9, wherein the ribs are disposed in a row and at specific intervals from each other.

12. The bill accumulation device of claim 9, wherein each of the ribs is disposed on an external wall.

13. The bill accumulation device of claim 9, wherein the grooves are V-shaped in cross-section.

14. The bill accumulation device of claim 13, wherein the curved potion comprises an inside curved portion at a side nearer to the guide member and an outside curved portion at an opposite side.

15. The bill accumulation device of claim 9, further comprising an external wall to which the ribs are formed, wherein a height of each of the ribs and intervals between the ribs are set such that leading end portions of the bills with a skew do not hit the external wall.

16. A bill accumulation device, comprising:

a front guide;

a reverse guide;

an accumulation space for bills;

a bill stopper provided on the front guide for receiving and stopping bills discharged by a conveying means;

a stage, upon which the bills that have been received and stopped by the bill stopper, are stacked; and

a plurality of elongated shaped ribs each extending in a rib long length direction, and each having a plurality of V-shaped grooves that extend along a rib short length direction, the ribs, in the rib long length direction, being respectively disposed orthogonal to the bills being discharged, the ribs being disposed in a row at specific intervals from each other on both sides of the front guide, the grooves on each of the ribs being profiled with an outside curved portion at a side opposite of a front guide side of the groove.

17. The bill accumulation device of claim 16, wherein each of the ribs is configured such that a maximum depth of the ribs in the bill discharge direction is shorter than a depth of the front guide in the bill discharge direction.

18. The bill accumulation device of claim 16, wherein

the grooves on each of the ribs are profiled with an inside curved portion on the front guide side of the groove;

and

a curvature of the outside curved portion is more gentle than a curvature of the inside curved portion.
