Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is generally directed to the field of currency handling machines, and in particular to a note hopper for dispensing paper currency, bank notes or cash equivalent scrip.




2. Description of the Prior Art




The advent of wide-spread use of bill acceptors or currency validation units for use with gaming machines and vending machines has greatly increased the convenience to the user by allowing the use of paper bills in various denominations, as opposed to coins, to operate these types of machines. Generally, however, these types of machines only dispense money in the form of coins and they are incapable of dispensing paper currency. Coincidentally, the wide-spread use of automated transaction machines (ATMs) has provided the consuming public with ready access to paper currency from ATMs using a bank card or credit card and upon entry of user appropriate code information. Operationally, however, ATMs are predominantly intended to dispense currency in a single denomination from a secure location and they are thus little more than a note counting and dispensing apparatus.




For certain applications, such as gaming and vending machines having bill validation capabilities, there is a need for a bill or note dispenser which will interact with an electronic controller of the machine, to dispense currency, bills, or other secure notes.




An object of the present invention is to provide a note holding and dispensing device which can discharge notes from a cassette removably attached to a frame.




Another object of the invention is to provide a note holding and dispensing device which can recover unacceptable notes such as double or false notes without the discharging these notes to avoid trouble with users.




Still another object of the invention is to provide a note holding and dispensing device with a cassette which includes an extracting device wherein a frame supports an extraction drive means which drives the extracting device to manufacture the cassette in light weight.




A further object of the invention is to provide a lightweight note holding and dispensing device electrically connectable to a host machine.




A still further object of the invention is to provide a note holding and dispensing device with a cassette lock device for securing a cassette to a frame wherein delivery and recovery slots in the cassette can be opened and closed by operation of the cassette lock device for anti-theft.




SUMMARY OF THE INVENTION




A note holding and dispensing device according to the present invention comprises a frame (


16


) formed with a cavity (


112


); a cassette (


18


) removably positioned in the cavity (


112


) of the frame (


16


) for holding a plurality of notes (


66


); a transfer device (


24


) comprising an extraction drive means (


120


) and a conveyer means (


122


) provided in the frame (


16


); and an electronic controller (


46


) for controlling operation of the extraction drive means (


120


) and conveyer means (


122


) of the transfer device (


24


). The cassette (


18


) has a chamber (


64


) for receiving the notes (


66


) and an extracting device (


232


) for discharging the notes (


66


) in the chamber (


64


). The extraction drive means (


120


) operates the extracting device (


232


) in the cassette (


18


) to fetch the notes (


66


) from the cassette (


18


). The conveyer means (


122


) transports the notes (


66


) received from the cassette (


18


) to an outlet (


20


) through a passageway (


22


).




The electronic controller (


46


) generates drive signals to operate the extraction drive means (


120


) and conveyer means (


122


) of the transfer device (


24


) so that the notes (


66


) can be successively dispensed from the removably and exchangeably mounted cassette (


18


) through the passageway (


22


). In this case, the cassette (


18


) can be made in light weight because the extracting device (


232


) can be driven by the extraction drive means (


120


) attached to the frame (


16


). The term “note” herein is used to mean all valuable paper such as bill, paper currency, bank notes, coupons, scrip, or other “secure” paper with an associated cash value.




In an embodiment of the instant invention, the cassette (


18


) comprises a storage area (


68


), and a diverting device (


230


) for receiving an unacceptable note (


66


) from the conveyer means (


122


) and forwarding the same to the storage area (


68


). The transfer device (


24


) comprises at least a sensor means (


30


,


32


) provided by the passageway (


22


) for detecting the unacceptable note (


66


) that is moved through the passageway (


22


), and a diverting means (


183


) for diverting the unacceptable note (


66


) from the passageway (


22


) to a recovery path (


48


) for the storage area (


68


) in the cassette (


18


). Upon detection of the unacceptable note (


66


) by the sensor means (


30


,


32


), the electronic controller (


46


) operates the diverting means (


183


) to guide the note (


66


) from the passageway (


22


) to the recovery path (


48


) in order to recover unacceptable note (


66


) such as double or false notes without discharging these notes to avoid trouble with users.




The sensor means (


30


,


32


) includes an optical sensor (


30


,


32


) for detecting double notes (


66


) moved through the passageway (


22


) to produce a detection signal so that the electronic controller (


46


) operates the diverting means (


183


) to divert the note (


66


) from the passageway (


22


) to the recovery path (


48


) when receives the detection signal of the double notes (


66


) from the optical sensor (


30


,


32


). The optical sensor (


30


,


32


) detects characteristics of the note (


66


) travelling along the passageway (


22


) and forwards output signals indicative of the note characteristics to the electronic controller (


46


). The electronic controller (


46


) comprises a microprocessor (


50


) for receiving the output signals from the optical sensor (


30


,


32


) to validate the note (


66


) in comparison of the received output signals with stored signal parameters. The electronic controller (


46


) operates the diverting means (


183


) to divert the note (


66


) from the passageway (


22


) to the recovery path (


48


) when receives the detection signal from the optical sensor (


30


,


32


) that the note (


66


) is not genuine.




The transfer device (


24


) comprises an extraction motor (


124


) and a transport motor (


150


) both controlled by the electronic controller (


46


) so that the extraction motor (


124


) provides the extraction drive means (


120


) with a drive force, and the transport motor (


150


) provides the conveyer means (


122


) with a drive force when the note (


66


) is extracted from the chamber (


64


) of the cassette (


18


).




The transfer device (


24


) comprises an entry detecting sensor (


198


) for detecting a leading edge of the note (


66


) extracted from the cassette (


18


) to the passageway (


22


) to produce a detection signal so that the electronic controller (


46


) ceases operation of the extraction motor (


124


) when receives the detection signal from the entry detecting sensor (


198


). Also, the transfer device (


24


) comprises an outlet sensor (


42


) for detecting existence of the note (


66


) which partially extends outward from the passageway (


22


) through the outlet (


20


) to produce a detection signal so that the electronic controller (


46


) ceases operation of the transport motor (


150


) when receives the detection signal from the outlet sensor (


42


). Moreover, the transfer device (


24


) comprises a post-validation sensor (


40


) for detecting a leading edge of the note (


66


) to produce a detection signal so that the electronic controller (


46


) operates the diverting means (


183


) to divert the note (


66


) from the passageway (


22


) to the recovery path (


48


) when receives the detection signal from the post-validation sensor (


40


) and decides that the note (


66


) is unacceptable in view of the outputs from the sensor means (


30


,


32


).




The cassette (


18


) comprises a casing (


62


); a lid (


60


) pivotally mounted on the casing (


62


) to cover the chamber (


64


) and storage area (


68


); and a lock means (


70


,


72


) for securing the cassette (


18


) to the frame (


16


) and for securing the lid (


60


) to the casing (


62


). The cassette (


18


) further includes a sealing device (


270


) which comprises a metallic plate (


272


) movable in parallel relation to a lid (


60


) between a shut position for covering delivery and recovery slots (


226


,


218


) and a release position for opening the delivery and recovery slots (


226


,


218


); a closure spring (


274


) for resiliently urging the metallic plate (


272


) toward the shut position; and an operative member (


275


) for moving the metallic plate (


272


) to the release position against elastic force of the closure spring (


274


) at the same time the cassette (


18


) is secured to the frame (


16


) by operation of the cassette lock means (


70


).




The lid (


60


) comprises a delivery slot (


226


) through which the notes (


66


) are delivered from the cassette (


18


) to the passageway (


22


); and a recovery slot (


218


) through which the unacceptable note (


66


) is retired from the passageway (


22


) to the chamber (


64


).




The note holding and dispensing device (


10


) is removably attached to a host machine (


12


) so that the transfer device (


24


) is controlled by the host machine (


12


) and forwards inner information to the host machine (


12


). Accordingly, the note holding and dispensing device (


10


) can be manufactured in small size to electrically connect the host machine (


12


). A chassis (


14


) may be provided to envelop the frame (


16


) so that the note holding and dispensing device (


10


) is detachably attached to the host machine (


12


) together with the chassis (


14


).




The extracting device (


232


) of the cassette (


18


) includes rollers (


258


,


260


) to which an uppermost one of the notes (


66


) retained in the chamber (


64


) is in contact; a first driven gear (


234


) for rotating the rollers (


258


,


260


); and fin gears (


264


) adjacent to the rollers (


258


,


260


) for selecting only the uppermost note (


66


) supplied by the rollers (


258


,


260


).




The chamber (


64


) and storage area (


68


) are positioned adjacent to each other in the cassette (


18


), and the notes (


66


) in the chamber (


64


) are supported on a tray (


200


) of a support (


202


) so that the notes (


66


) are resiliently forced toward the extracting device (


232


) by a compression spring (


204


).




When the notes (


66


) are filled in the chamber (


64


), a pin (


203


) of a support (


202


) is engaged with a latch (


220


) provided on the bottom of the chamber (


64


) of the cassette (


18


). The latch (


220


) is connected with a sliding plate (


222


) which extends toward a rear surface of a casing (


62


) so that the sliding plate (


222


) serves to release engagement of the latch (


220


) and pin (


203


) upon contact of the sliding plate (


222


) to a protrusion (


16




a


) of the frame (


16


) when the cassette (


18


) is positioned in the frame (


16


) thereby causing the uppermost note (


66


) to come into contact to rollers (


258


,


260


).




The first driven gear (


234


) of the extracting device (


232


) is meshed with a second driven gear (


148


) positioned at the bottom of the transfer device (


24


) to rotate the first driven gear (


234


) by an extraction motor (


124


) through the second driven gear (


148


). The cassette (


18


) comprises a picker wheel (


262


) rotatably mounted in the casing (


62


) opposite to the fin gears (


264


) for preventing extraction of the double notes (


66


) at a leading edge of a pathway guide (


248


), said picker wheel (


262


) being rotatable only in one direction.




The diverting means (


183


) comprises a lever (


184


) rotatably mounted between a discharge position for opening the passageway (


22


) toward the outlet (


20


) and a recovery position for opening the passageway (


22


) toward the diverted slot (


44


); and an actuator (


182


) for moving the lever (


184


) toward one of the discharge and recovery positions. The diverting means (


183


) further comprises a biasing spring (


186


) for moving the lever (


184


) toward the other of the discharge and recovery positions.




The conveyer means (


122


) comprises a drive roller (


190


) and a tension roller (


192


) provided adjacent to the outlet (


20


) in opposite relation to each other. When the rear end of the note (


66


) is sandwiched between the drive and tension rollers (


190


,


192


) after the note (


66


) passes a post-validation sensor (


40


), the electronic controller (


46


) ceases operation of the transport motor (


150


) to stop movement of the note (


66


).




When the electronic controller (


46


) judges that the note (


66


) is unacceptable in view of the optical sensor (


30


,


32


) and also receives the detection signal from the post-validation sensor (


40


), the electronic controller (


46


) operates the actuator (


182


) to rotate the lever (


184


) to the recovery position.




The frame (


16


) further comprises an installation detection switch (


114


) for detecting the cassette (


18


) in the cavity (


112


) to produce a detection signal to the electronic controller (


46


).




The cassette (


18


) further comprises an empty detection sensor (


282


) for detecting reduction of the notes (


66


) in the chamber (


64


) to produce a detection signal so that the electronic controller (


46


) operates a warning system when receives the detection signal from the empty detection sensor (


282


).

DETAILED DESCRIPTION OF THE INVENTION




As shown in

FIG. 1

, a note holding and dispensing device


10


, which may removably be incorporated into of an electronically controlled host machine


12


such as such as a gaming machine, vending machine or cash box, can hold and conveniently dispense bills to users. The device


10


is electrically controlled by the host machine


12


to dispense notes or currency of a predetermined denomination.





FIG. 2

depicts a perspective view of the note holding and dispensing device


10


removed from the host machine


12


of FIG.


1


. The note holding and dispensing device


10


includes a chassis


14


designed to be secured on or into the host machine


12


. The chassis


14


contains a cassette


18


and a transfer device


24


received in a frame


16


and, as shown removed from the chassis


14


in

FIGS. 3 and 4

, respectively.




As depicted in FIG.


2


and in the view of

FIG. 3

, the transfer device includes an outlet


20


from which currency can be dispensed. The outlet


20


for dispensing currency is the opening at the end of a passageway


22


defined by a transfer device


24


which generally comprises a lid device


26


and a shelf


28


. The lid device


26


and shelf


28


may include one or more sensors (sensor means)


30


,


32


, such as magnetic or preferably optical infrared sensors, for detecting identifying characteristics of bills and notes and authenticating each bill or note which is to be dispensed.




The transfer device


24


includes “double-bill” check and bill validity detection systems to assure that each bill or note is authentic and is dispensed individually. In the event that a double bill detection event occurs, the frame


16


diverts the double bill to storage area


68


in the note holding and dispensing device


10


, by redirecting the travel path of the double bill so that it is not dispensed.




The shelf


28


may also include a post-validation sensor


40


such as a lever sensor to detect the passage and position of the bill or note within the transfer device


24


. In addition, the shelf


28


may include an outlet sensor


42


such as a lever sensor which operates to provide a signal to prevent dispensing of a subsequent note prior to removal of a preceding note.




The optical sensors


30


and


32


, lever sensors


40


and


42


and the drive mechanisms or motors are coupled to and electronically controlled by an electronic controller


46


within the note holding and dispensing device


10


. The electronic controller


46


also provides all control functions and allows communications with the host machine


12


(FIG.


1


).




As depicted in

FIG. 3

, the shelf


28


also includes a diverted slot


44


which provides an opening to a recovery path


48


for allowing double or overlapped bills or other type of rejected note to be stored in the note holding and dispensing device


10


.





FIG. 4

depicts a perspective view of the cassette


18


extracted from the frame


16


. The cassette


18


includes a lid


60


attached to a frame


62


. The frame


62


includes a chamber


64


which allows the storage of a plurality of coupons, currency, notes or bills


66


. The note holding and dispensing device


10


stores and dispenses paper currency, bank notes or “secure” paper such as printed coupons or scrip. Such currency is conveniently dispensed from note holding and dispensing device


10


, so that it may be accepted by a user. At the front portion of the cassette


18


is a storage area


68


which is positioned below the diverting slot


44


of the shelf


28


upon installation of the cassette


18


into the frame


16


.




Preferably, the cassette


18


includes double lock assemblies which include a cassette lock device


70


to be used to secure the cassette


18


within the frame


16


, and a lid lock device


72


to be used to secure the lid


60


to the frame


62


to thereby secure access to notes held in the cassette


18


when it is removed from the frame


16


. The double lock assembly also preferably requires two keys


74


and


76


respectively, to open the cassette


18


and allow access to the currency storage area


64


.




In operation, the frame


16


extracts bills from the cassette


18


, verifies that only one bill has been extracted by sensing characteristics of the bill via optical sensors


30


and


32


, and sequentially dispenses the bills through outlet


20


. The note holding and dispensing device


10


can be configured such that “secure” paper such as coupons or scrip, having exchangeable monetary value, can be dispensed. Such secure paper


66


would preferably be designed to be inserted into and recognized by compatible currency acceptor or bill validator machines.





FIG. 5

is a block diagram schematically showing a microprocessor controller


46


for the note holding and dispensing device


10


of the present invention. The device


10


is controlled by electronic instructions from the host machine


12


. When non-currency secure paper is to be dispensed, such paper preferably incorporates in its design and/or manufacture, characteristics to allow it to be scrutinized and validated by bill validators and other electronic currency validation, stacking and sorting devices. At the heart of the microprocessor controller


46


is a microprocessor


50


. The microprocessor


50


relies upon programming instructions stored in a code read-only memory (ROM)


52


, in which is stored programming and execution instructions. The microprocessor


50


of the note holding and dispensing device


10


, may also be connected to an electronic controller for a host machine including a bill validator so that the components can share control functions relating to the validation proceedings for bills and notes.





FIGS. 6 and 7

depict detailed cross-sectional left side and top views, respectively, of the frame


16


of

FIG. 3

, and particularly the components of the transfer device


24


thereof. In the cross-sectional left side view of

FIG. 6

, the cassette


18


has been removed from the frame


16


. The cassette


18


is intended to be placed in a cavity


112


, located in the lower portion of the frame


16


. The frame


16


includes a “cassette installed” lever switch


114


as depicted near the bottom left corner, which produces an electric signal to confirm to the electronic controller


46


that the cassette


18


is positioned within the currency bay


112


.




Referring to

FIGS. 6 and 7

, the transfer device


24


of the frame


16


includes an extraction drive means


120


and a conveyer means


122


. The extraction drive means


120


provides the driving elements in order to drive a first driven gear


234


located within the cassette


18


which in turn drives rollers


258


,


260


to advance a bill out of the cassette


18


and into the passageway


22


of the transfer device


24


. The conveyer means


122


, by comparison, provides a belt drive system to engage the note with a belt


178


while an entry detecting sensor


198


senses the note once it enters the passageway


22


and advance the note either to the outlet


20


or to and through diverting slot


44


into the storage area


68


.




The extraction drive means


120


includes a motor


124


with a shaft


126


on which is mounted both a drive gear


128


and a rotating position indicator


130


. The rotating position indicator


130


is sensed by a motor encoder sensor


132


which provides an output signal to the electronic controller


46


indicative of the rotational position of the motor


124


and thereby the rate at which a note is advancing, in order to allow the synchronization of the note advance for purposes of sensor validation of the note information by the electronic controller


46


.




The drive gear


128


drives, through a sequence of speed reducing gears


140


,


142


,


144


and


146


, and a second driven gear


148


. The second driven gear


148


extends slightly downward from the bottom portion of the transfer device


24


so that it may engage the first driven gear


234


in the cassette


18


described subsequently with respect to FIG.


8


.




The conveyer means


122


includes a motor


150


having a shaft


152


on which is mounted a drive gear


154


and a rotational position indicator


156


. The rotational position indicator


156


is sensed by a motor encoder sensor


158


which provides output signals to the electronic controller


46


in a manner similar to the motor encoder sensor


132


discussed above.




The drive gear


154


drives, also through a sequence of speed reducing gears


160


,


162


,


164


,


166


, a driven gear


168


and an idler gear


170


. The driven gear


168


is mounted on a shaft


172


to drive a belt drive wheel


174


. The belt drive wheel


174


in turn drives the belt


178


which extends toward the opposite end of the transfer device


24


, where it is wrapped about a belt tension roller


180


.




As would be seen if viewed from the left side view of

FIG. 6

, the belt


178


generally rotates in a clockwise direction so that the upper side of the belt


178


, advances from the top of belt tension roller


180


to the drive wheel


174


, and thus from the back of the transfer device


24


to the front of the transfer device


24


, to drive a note which is positioned above the belt


178


from the back to the front of the transfer device


24


along the top of the shelf


28


and within the passageway


22


.




As discussed above, the transfer device


24


allows the note holding and dispensing device


10


to direct an invalid bill or note to a storage area


68


in the cassette


18


. In order to extract an invalid bill from the passageway


22


, a actuator


182


such as solenoid or motor activates a set of deflector or diverting levers


184


which are positioned before the end of the passageway


22


to shift the invalid bill from the passageway


22


to the storage area


68


. During normal operation, the actuator


182


is powered on to hold the set of diverting levers


184


down so that a bill can pass along the passageway


22


to outlet


20


. If a double or invalid note is detected, power to the actuator


182


is shut off, and a spring


186


biases the diverting levers


184


to rotate into a position whereby they cause an advancing note to rotate along the inner surface diverting levers


184


and the outer surface of the belt drive wheel


174


, while driven by belt


178


, so that instead of advancing horizontally out through the outlet


20


, the bill will rotate around the outside of belt drive wheel


174


through a ninety degree angle, and proceed vertically downward through diverting slot


44


.




In order to provide positive tracking near the end of the passageway


22


as well as in the recovery path


48


, a tension roller


188


is positioned in front of, and in rotational contact with, the belt drive wheel


174


. The combination of the tension roller


188


and the frictional contact with the belt


178


will positively advance a bill positioned therebetween. In addition, the tension roller


188


also drives, by rolling contact, a drive roller


190


positioned just inside of outlet


20


. The drive roller


190


is also in frictional rolling contact with a tension roller


192


mounted so as to be vertically positioned above drive roller


190


within the lid device


26


.




In order to detect the position of the note as it exits the outlet


20


, the mechanical lever sensor


42


is located proximally to outlet


20


. The mechanical lever sensor


42


is electrically connected to the electronic controller


46


to communicate an electric signal indicating when a note dispensed by the note holding and dispensing device


10


is removed from the outlet


20


. The electronic controller


46


of the note holding and dispensing device


10


may be programmed so that the motor


150


will stop when the trailing end of a bill is held between drive roller


190


and tension roller


192


, maintaining the mechanical lever sensor


42


in a closed position, so that only one bill is dispensed at a time. Once the bill is removed, the mechanical lever sensor


42


will open, sending a signal to the electronic controller


46


, and the extraction and transport motors


124


and


150


can be activated to transport another bill from the cassette


18


to outlet


20


. Thus when it is desired to dispense only one bill at a time, the electronic controller


46


will not direct power to the extraction and transport motors


124


and


150


until the mechanical lever sensor


42


moves to an open position indicating that the last dispensed bill has been removed.




The transfer device


24


also includes the post-validation sensor


40


positioned along the passageway


22


before the diverting slot


44


but spaced from optical sensors


30


,


32


a distance greater than the length of a bill traveling along the passageway


22


. The post-validation sensor


40


provides an indication of the passage of the leading edge of a bill as it advances along the passageway


22


. The post-validation sensor


40


is electrically connected to the electronic controller


46


, so that if an invalid or double bill is detected by the optical sensors


30


,


32


, and identified by the electronic controller


46


, its initial contact with lever sensor


40


will cause the electronic controller


46


to activate the bill divert function, shutting off power to the actuator


182


, as discussed above.




The lid device


26


further includes a number of tensioning rollers


82


,


84


,


86


,


88


and


192


. These tensioning rollers


82


,


84


,


86


,


88


and


192


assist in maintaining the bill essentially flat while it advances along the top surface of belt


178


and shelf


28


. Each of the tensioning rollers


82


,


84


,


86


,


88


and


192


is driven by the belt


178


, or by the advancement of a bill between the respective tension roller and belt


178


. As shown in

FIG. 7

, the tension rollers


104


and


108


may be pivotally mounted on roller frames


92


,


94


, respectively, so that in the event a note gets jammed in the passageway


22


, it can be removed by lifting the roller frame


92


or


94


to access the passageway


22


.




The lid device


26


also includes the optical sensor


30


such as a light sensitive transistor which cooperates with the oppositely disposed optical sensor


32


such as a light emitting diode mounted in the transfer device


24


. The optical sensors


30


and


32


provide electronic signal information to the electronic controller


46


concerning identifying characteristics of the bill being transported between optical sensors


30


and


32


along the passageway


22


. The optical sensor information is synchronized with the position and travel speed of the bill by the electronic controller


46


so that a “bill characteristics” signal, comprised of the sensed identifying characteristics for the entire length of the bill


60


, can be obtained for each note or bill


66


. In this manner, the electronic controller


46


can compare the bill characteristics signal to one or more sets of bill characteristics parameters stored in the ROM


52


of the electronic controller


46


, to discriminate between a valid single note and a double note or a defective note.




In the instance where the optical sensors


30


and


32


provide a signal which indicates to the electronic controller


46


that a double note is being passed through the passageway


22


, or that the note is for some reason invalid, the diverting means


183


are activated so that the note will be diverted into the storage area


68


, as discussed above, and another note is extracted from note cassette


18


, validated and dispensed.




The lid device


26


also further includes the entry detecting sensor


198


which senses the beginning and leading edges of the note


66


as it advances proximate the beginning of the passageway


22


within the transfer device


24


from the cassette


18


. The entry detecting sensor


198


is electrically connected to the electronic controller


46


to provide electrical signal output information thereto. In this manner, and in combination with the motor encoder sensors


132


and


158


for the motors


124


and


150


, respectively, the optical sensors


30


and


32


can be precisely controlled in operation over the length of the note as it passes between optical sensors


30


and


32


.





FIG. 8

depicts a detailed side cross-sectional view of the cassette


18


removed from the frame


16


.

FIG. 9

depicts a detailed top cross-sectional view of the cassette


18


. As depicted in

FIG. 8

in the operating position, the cassette


18


includes the lid


60


attached to the top of the frame


62


to cover the chamber


64


and storage area


68


.




As depicted in

FIGS. 8 and 9

, the cassette


18


includes a tray


200


for supporting a plurality of coupons, currency, notes, or bills


66


located inside the chamber


64


. The tray


200


is attached to a support assembly


202


which is configured to support the tray


200


through vertical translation while also maintaining the tray


200


horizontally flat. The support assembly


202


comprises a pair of links


202




a


and


202




b


, a pin


203


which connects these links


202




a


and


202




b


and a compression spring


204


for upwardly biasing the tray


200


. The cassette


18


also includes a latch


220


located on the bottom of the chamber


64


to allow the tray


200


to be latched onto the pin


203


at its vertically lowest position of the tray


200


so that the notes


66


may be placed in the chamber


64


. The latch


220


is connected to a sliding plate


222


which extends to the rear surface of frame


62


and is elastically urged outwardly by a spring


222




a


so as to engage the latch


220


with the pin


203


. When the cassette


18


is inserted in the cavity


112


of the frame


16


, the sliding plate


222


engages a protrusion


16




a


of the frame


16


to cause the latch


220


to unlatch and release the pin


203


of the tray


200


. The compression spring


204


will then bias the tray


200


vertically upward until the top bill contacts the rollers


258


,


260


.




The cassette


18


further includes a extracting device


232


located in the lid


60


. The extracting device


232


includes the first driven gear


234


which extends slightly upward from the upper portion of the cassette


18


so that the first driven gear


234


can engage the second driven gear


148


located on the bottom portion of the transfer device


24


, described above with respect to FIG.


6


. The first driven gear


234


drives, through a sequence of gears


236


,


238


,


240


,


242


and


244


, shafts


254


and


256


, on which are mounted rollers


258


and


260


, respectively, as shown best in FIG.


9


. Generally, these rollers


258


and


260


may be made of rubber or another suitable elastic material which can engage and force paper currency or notes along a defined pathway. A pathway guide


248


attached to frame


62


, can be for example made of a hard plastic material and is shaped to have a part-cylindrical surface to direct a note or coupon through a pathway


224


and towards slot


226


, where the note would then enter the transfer device


24


.




A picker wheel


262


is rotatably mounted to the frame


62


at the leading edge of pathway guide


248


to prevent double bills from being extracted from the cassette


18


. The picker wheel


262


can be rotated only in one direction to provide one bill at a time to the frame


16


. The circumference of the picker wheel


262


comprises a suitable material for causing friction against the leading edge of a note or bill


66


. The picker wheel


262


may be configured to only rotate in one direction, which is opposite the direction of travel of the note.




A diverting device


230


is shown in

FIG. 9

positioned toward the front of the cassette


18


and positioned in the lid


60


of cassette


18


. As shown in

FIGS. 6 and 9

, the diverting device


230


includes a driven gear


250


that engages the idler gear


170


of the transfer device


24


to drive rollers


266


,


268


. Driven gear


250


is mounted on a shaft


251


together with a roller


266


, and a roller


268


is in driving contact with the roller


266


through rolling contact so that the driven gear


250


can rotate the roller


266


which drives the roller


268


in turn respectively as shown in

FIG. 9

, for diverting a double bill, or a crumpled or torn bill, to the storage area


68


. Any note or bill that is rejected will pass from the frame


16


to the cassette


18


through a slot


218


. When the cassette


18


is installed in the frame


16


, the slot


218


will be positioned vertically below the recovery path


48


. As shown in

FIG. 9

, the lid


60


may also include openings


276


, which allow for visual inspection of the chamber


64


, and bills therein.




A sealing device


270


is slidably disposed within the lid


60


, where it is biased into a “closed” position by a spring


274


. The sealing device


270


includes a metallic plate


272


for covering slots


218


and


226


of the lid


60


, for security whenever the cassette


18


is removed from the frame


16


. When the cassette


18


is placed inside of the frame


16


, the sealing device


270


is unlocked through operation of the cassette lock device


70


which locks the cassette


18


to the frame


16


. This allows the metal plate


272


in the sealing device


270


to slide horizontally and uncover the recovery and delivery slots


218


and


226


in the lid


60


, thus allowing operation of the note holding and dispensing device


10


. The sealing device


270


is implemented to cover the recovery and delivery slots


218


and


226


as well as openings


276


to prevent unauthorized access into the cassette


18


.




The top cross-sectional view of the lid


60


of the cassette


18


is shown in greater detail in FIG.


9


. The first driven gear


234


is shown connected to gear


236


via a common shaft


235


, and the gear


236


drives gears


238


,


240


,


242


and


244


. The gears


240


and


242


are attached to shafts


254


,


256


on which are mounted rollers


258


and


260


, formed from an elastic substance such as rubber. As understood from

FIGS. 8 and 9

, first driven gear


234


is attached to fin gears


264


on a common shaft


235


in order to aid the selection of only the top bill from the stack of bills and to further bill or note advancement. Fin gears


264


include a series of fins, comprising a material such as rubber, which are aligned radially around the circumference of a shaft. The fin gears


264


help ensure that only one bill is selected and advanced along the pathway


24


at a time.





FIG. 10

depicts a view of the rear surface of the cassette


18


and includes the frame


62


and the lid


60


. The distal end of the sliding plate


222


for the latch


220


, projects from the rear surface. In addition, the rear surface includes a tray empty switch


280


, and a near empty optical sensor


282


, which are shown on the rear portion of the frame


62


.




In operation, a user lifts the lid


60


of the cassette


18


and places a plurality of coupons, currency, notes, or bills


66


onto the tray


200


which is depressed until held in place by the latch


220


because the pin


203


is brought into engagement with the latch


220


. This condition is detected by the tray empty switch


280


which generates a detection signal to the electronic controller


46


. After the lid


60


is closed, the cassette


18


is placed inside the transfer device


24


which causes the latch


220


to unlatch, thus releasing the tray


200


. Accordingly, the installation detection switch


114


is turned on to produce a detection signal which is forwarded to the electronic controller


46


to recognize the installation of the cassette


18


. Simultaneously, the sliding plate


222


is brought into contact with the protrusion


16




a


of the frame


16


to push the latch


220


so that the pin


203


is disengaged from the latch


220


to release the tray


200


. Thus, the compression spring


204


then forces the tray


200


upward, causing the uppermost bill


66


to come into contact with the extracting device


232


. In this condition, the cassette


18


is locked to the frame


16


by operation of the cassette lock device


70


which simultaneously moves the operative member


275


to slide the metallic plate


272


from the shut position to the release position to open the delivery and recovery slots


226


and


218


to the transfer device


24


. The driven gear


250


is brought into engagement with the idle gear


170


of the transfer device


24


, and the first driven gear


234


is brought into engagement with the second driven gear


148


.




When a signal is received from the electronic controller


46


of the note holding and dispensing device


10


, the extracting device


232


activates the rollers


258


,


260


, picker wheel


262


and fingers


264


to advance a single bill or note along pathway


224


to exit the cassette


18


at slot


226


. Thus, the bill


66


is first advanced along a horizontal path towards the rear section of cassette


18


. During this transit operation, the picker wheel


262


is designed to prevent more than one note or bill from advancing along the pathway


224


. As the leading edge of the bill is slid into the pathway guide


248


, the bill is forced by the pathway guide


248


to rotate ninety degrees so that it is directed upward, towards the top of the cassette


18


where it exits out of the slot


226


and enters the passageway


22


in the frame


16


.




When the entry detecting sensor


198


, as shown in

FIG. 6

, is actuated by the leading edge of the advancing bill, the trailing edge of the bill will have passed beyond rollers


258


and


260


. Accordingly, the electronic controller


46


sends a signal shutting off the extraction motor


124


so that the extracting device


232


will no longer be actively driven and the rollers


258


and


260


will stop rotating and rest on the next bill. Therefore, the next bill in the stack will be held in place in the chamber


64


, and will not advance along with the bill being pulled through the passageway


22


. In addition, the rollers


258


and


260


will stop rotating as soon as the trailing edge of the bill has advanced from underneath rollers


258


and


260


.




By the time the leading edge of the bill extracted from the cassette


18


causes the entry detecting sensor


198


to move to the closed position, the leading edge of the bill has come into contact with the belt


178


which is being driven by transport motor


150


. The motor encoder sensor


158


associated with the rotating position indicator


156


for motor


150


provides a signal to the electronic controller


46


which can be interpreted to determine the exact speed of the translation of the bill along the passageway


22


. Thus, the electronic controller


46


will be able to determine when the leading edge of the bill


66


reaches the optical sensors


30


and


32


. During the time that the bill passes length wise between optical sensors


30


and


32


, the bill would be moving at a constant speed so that bill characteristic data produced by the outputs of sensors


30


and


32


may be communicated to the electronic controller


46


in accordance with the linear length of the bill. By the time the length of the bill has passed between sensors


30


and


32


, the electronic controller


46


will have determined whether the bill is a valid bill, or if there are two bills stuck together forming a double bill. At the time that the bill has completed its passage between sensors and


30


and


32


, it will be in approximately the midpoint of the passageway


22


and the leading edge will have not yet reached the post-validation sensor


40


. As soon as the leading edge trips the post-validation sensor


40


, in the event that a double bill or an invalid bill has been detected, the electronic controller


46


will shut off power to the actuator


182


and the diverted levers


184


will rotate upwards so as to deflect the leading edge of the bill from passageway


22


into recovery path


48


, the bill will be turned through a ninety degree rotation to proceed vertically downward into the storage area


68


.




When the sensor data from sensors


30


and


32


is interpreted by the electronic controller


46


as indicative of a valid note or secure script, then the diverted levers


184


will remain in the retracted position and the leading edge of the bill will exit through outlet


20


. Again, using the information from the motor encoder sensor


158


which senses the rotational position of the drive motor


150


, the electronic controller


46


can calculate the proper length of time to power the drive motor


150


to allow the trailing edge of the bill being dispensed to advance to a point where it is held between drive roller


190


and tension roller


192


. When the trailing edge of the bill is positioned between drive roller


190


and tension roller


192


, the electronic controller


46


will shut off power to the transport motor


150


and the advancement of the bill will be stopped. The trailing edge of the bill will be held between drive roller


190


and tension roller


192


. The user may then simply pull the bill from the machine to accept the dispensed bill. Once the trailing edge of the bill passes lever sensor


42


, the lever sensor


42


will move to the open position and the electronic controller


46


can determine if another bill is to be dispensed. If so, the extraction and transport motors


124


and


150


can be activated and, as discussed above, the procedure for dispensing a bill is repeated.




When the tray


200


is reduced to a small number of bills or notes, such as approximately 10, the near-end optical sensor


282


sends a signal to the electronic controller


46


to activate a warning system. In addition, when the tray


200


is completely empty, the tray empty switch


280


sends a “tray empty” signal to the electronic controller


46


. This information may then be communicated to the host machine


12


(FIG.


1


).




The configuration of the note holding and dispensing device


10


and the elements thereof are preferably designed to enhance security of the currency contained in the note holding and dispensing device, including during transport of the cassette


18


when it is withdrawn from the note holding and dispensing device


10


. Thus, it should be noted that the system operates in a mode whereby only one bill is extracted from the cassette


18


, it is then validated and, only if valid, dispensed by the note holding and dispensing device


10


. If for any reason the note is not validated by the information provided by optical sensors


30


and


32


, it is simply diverted into the storage area


68


. Specifically, immediately after the leading edge of the bill turns the post-validation sensor


40


on, if the electronic controller


48


detects double bills or unacceptable bill, it ceases output to the actuator


182


to move the diverting means


183


upward by elastic force of the biasing spring


186


so as to deflect the leading edge of the bill from passageway


22


into recovery path


48


. Thus, the bill will be turned through a ninety degree rotation to proceed vertically downward into the storage area


68


. By default, the electronic controller


46


must determine that the bill should pass, otherwise it is automatically diverted to the storage area


68


.




The foregoing detailed description is provided to allow those skilled in the art to appreciate the present invention. It is contemplated, however, that such persons will readily understand the application of the note holding and dispensing device detailed herein in various types of machines which are available.
