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 front guide and a reverse guide, configuring an accumulation space for bills, and a bill stopper provided to the front guide for receiving and stopping bills discharged by conveying means, wherein:

the bill accumulation device stacks the bills that have been received and stopped by the bill stopper on a stage; and

a plurality of elongated shaped ribs formed along the rib length direction with a plurality of V-shaped grooves that extend along the rib short length direction are respectively disposed orthogonal to bills being discharged in a row at specific intervals from each other on both sides of the front guide.

2. The bill accumulation device of claim 1, wherein each of the ribs is formed to an external wall to which the front guide is attached such that the maximum depth formed in the bill discharge direction is shorter than the depth of the front guide along the discharge direction.

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

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

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

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

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

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

5. 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 the inside curved portion side to the 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.

6. The bill accumulation device of claim 4, 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 the inside curved portion side to the 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.
