## Background
BACKGROUND OF THE INVENTION
The present invention comprises a document rack attached to a fore or front side of a document validator to receive and retain documents discharged from the document validator.
Typically, automated bill handling machines such as vending machines, ticket machines and bill exchangers today utilize a bill validator that has its functions to discriminate authenticity of bills slipped into an inlet of the validator, to stow the bills considered genuine into a stacker provided in the validator and to return to the inlet the bills considered counterfeit. When the bill is returned to the inlet, it is kept at the inlet with the bill whose leading edge partly projects outward from the inlet to allow users to thoroughly draw the bill out of the inlet, otherwise the bill is wholly discharged from the inlet on a tray provided in front of and adjacent to the inlet of the vending machine.

DETAILED DESCRIPTION
Embodiments of the document rack according to the present invention will be described hereinafter in connection with FIGS. 1 to 16 of the drawings. Same reference symbols shown in FIGS. 1 and 16 indicate identical or similar portions in these drawings. The term “a document” or “documents” herein broadly means all or any of valuable papers including bills, currencies, plastic money, coupon tickets, tokens, tenders, credit cards, securities and scrip while the embodiments of the invention exemplifies bills dealt for bill validators.
The document rack according to the present invention has a housing 3 attached to a front side of a shield such as a door panel 15 of a gaming or vending machine by a suitable known fixing device such as bolts and nuts while a bill validator 1 is attached to a back side of door panel 15 to arrange a front portion 2 of bill validator 1 within housing 3.
Housing 3 comprises a front wall 4 formed with an opening 7, a back wall 5 formed with a notch 5a, and a bottom wall 6 connected to a lower end of back wall 5 to structurally constitute housing 3 by front, back and bottom walls 4, 5 and 6. Front wall 4 comprises a generally flat anterior wall 4a, a top wall 4b that has a curved top portion smoothly extending from anterior wall 4a and a horizontal top rear portion connected to the curved top portion and back wall 5, a pair of side walls 4c that each have a curved side portion smoothly extending from anterior wall 4a and a vertical rear portion connected to the curved side portion and a side of back wall 5. Each of side walls 4c has a curved lower side wall 4d connected between anterior wall 4a and bottom wall 6.
An inner chamber 10 is formed at the upper portion within housing 3 by anterior wall 4a, top wall 4b, side walls 4c and back wall 5, and a pocket 13 is formed below inner chamber 10 within housing 3 by anterior wall 4a, bottom wall 6, lower side walls 4d and back wall 5. Opening 7 formed on front wall 4 comprises an inlet opening 8 formed on anterior wall 4a and a discharge opening 9 below inlet opening 8. Removably attached to bottom wall 6 is an inverted channel-shaped guard fence 14 that compensates discharge opening 9 of front wall 4 to ensure prevention of bills from dropping out of pocket 13 between guard fence 14 and back wall 5. Pocket 13 serves to receive and retain bills that fall from outlet port 12 of front portion 2 of bill validator 1 and guard fence 14 also makes it easier for users to observe and access bills in pocket 13.
As seen from FIGS. 1, 5 and 10, back wall 5 of housing 3 may be secured to a front side of door panel 15, and bill validator 1 is attached to a back side of door panel 15 so as to set front portion 2 of bill validator 1 in inner chamber 10 after it is passed through a hole 16 formed in door panel 15 and through notch 5a of back wall 5. As seen in FIG. 1, front portion 2 of bill validator 1 comprises an inlet port 11, an outlet port 12, a passageway 20 communicated with inlet port 11 to guide a bill moved between inlet port 11 and the back of passageway 20, a discharge pathway 21 that branches at a bifurcation 22 from passageway 20 to communicate with outlet port 12 and a deflection device 25 arranged at bifurcation 22 for directing the bill from passageway 20 toward outlet port 12. Deflection device 25 may be moved between the reception position of FIG. 7 for connecting inlet port 11 to passageway 20 while shutting down discharge pathway 21 from passageway 20 and the discharge position of FIG. 1 for connecting passageway 20 to discharge pathway 21 while shutting down inlet port 11 from passageway 20. A conveyor and a validation sensor (both not shown in the drawings) are provided in bill validator 1.
As illustrated in FIGS. 11 to 14, deflection device 25 comprises a rotary shaft 30, a plurality of deflectors 31 mounted on rotary shaft 30 at regular intervals, a bell crank 32 attached to an end of rotary shaft 30 for integral rotation with rotary shaft 30, a tension spring 34 for constantly applying an elastic force on bell crank 32 to resiliently urge deflectors 31 toward a bottom surface 23 of passageway 20 so as to continuously keep deflector 31 in the reception position of FIG. 7. An actuator 26 such as a solenoid or motor is provided to have a reciprocating rod 28 whose outer end is pivoted by a pin 39 at one end of a lever 37 rotatably mounted on housing 3 by an axle 38 with the other end of lever 37 in contact to bell crank 32. Elastic force of tension spring 34 serves to resiliently keep reciprocating rod 28 of actuator 26 at the extended position, and simultaneously to keep deflector 31 in the reception position of FIG. 7 where deflectors 31 are in contact to bottom surface 23 of passageway 20 during deactivation of actuator 26 to allow users to slide bills into inlet port 11 of bill validator 1 through inlet opening 8.
When users insert bills into inlet port 11, bill validator 1 activates the conveyor and validator sensor to transport bills along passageway 20 and detect physical property of bills to automatically validate bills within bill validator 1. When the validator sensor considers inserted bills to be genuine, the conveyor transports them to a stacker (not shown) in bill validator 1. When the validator sensor does not consider inserted bills to be genuine, the conveyor returns them to inlet port 11 with deflectors 31 remaining at the reception position.
When actuator 26 is activated to inwardly pull reciprocating rod 28 to the retracted position, a lower end of lever 37 pushes bell crank 32 against elastic force of tension sprint 34 to rotate bell crank 32 and rotary shaft 30 to move deflectors 31 from the reception position of FIGS. 11 and 12 to the discharge position of FIGS. 13 and 14 away from bottom surface 23 of passageway 20.
Disposed opposite to deflector 31 is an impeller 27 that directs and transports bills from passageway 20 along discharge pathway 21 toward inner chamber 10. Impeller 27 has a drive shaft 40, a plurality of vanes 41 mounted on drive shaft 40 at regular intervals, a driven gear 42 secured at an end of drive shaft 40 and a drive motor 35 for driving driven gear 42 through a gear train 36 that has an input side meshed with a pinion 43 of drive motor 35 and an output side mesh with driven gear 42.
With deflector 31 retained at the reception position of FIG. 7 by means of elastic force of tension spring 34, a bill is inserted into inlet port 11 of validator 1 through inner chamber 10, and is inwardly delivered along passageway 20 by the conveyor over deflector 31 through the validator sensor to validate it because validator 1 accepts and stores inside only bills considered genuine and also reusable.
When bill validator 1 returns once accepted bills to outlet port 12 or dispenses charge with bill or bills from outlet port 12 for example in accordance with an instruction signal from a supervisory computer in a vending or bill handling machine, the conveyor begins to adversely transport bills from the back of passageway 20 toward outlet port 12, at the same time, actuator 26 is activated to move deflector 31 from the reception position to the discharge position while activating drive motor 35. As shown in FIG. 8, deflectors 31 divert bills through passageway 20 into discharge pathway 21 at bifurcation 22 to urge bills onto an inner surface of deflectors 31 by each tip of vanes 41 of impeller 27 so that each bill is moved along and between inner surface of deflectors 31 and an inner surface of front wall 4 of housing 3 to ensure the drop of bills into pocket 13 for dispensation as seen in FIGS. 9 and 10. Front wall 4 of housing 3 contributes to the prevention of bills from falling off pocket 13 when bills are discharged from outlet port 12 of bill validator 1.
In this way, the document rack may receive and retain bills dispensed from bill validator 1 to prevent scatter and contamination of issued bills. In addition, users can easily take out bills in a lump from the document rack for reuse of bills. Thus, the document rack makes it easier for users to handle bills discharged from document validator 1.
The foregoing embodiments of the prevent invention may be modified in various ways. For example, in place of panel 15, the document rack may be directly attached to a flange formed with a casing 2a that encases front portion 2 of bill validator 1 as shown in FIG. 16. The present invention is applicable to document racks used together with document validators that may dispense internally reserved documents from an outlet port of the validators.
