Description
~LlZ8478 This is a division of copending Canadian patent appli-cation Serial No. 301,331 which was filed April 18, 1978.
This invention relates to a banking machine, and more particularly to apparatus and the method of controlling the dispensing of bank notes from a banking machine.
Recent studies have shown that the general public is relying more heavily on the use of automatic banking machines to complete their financial transactions. There are many reasons advanced for this change from conventional banking for completing financial transactions to the use of automatic banking machines. One significant advantage, however, of the automatic banking machine is its availability on a twenty-four hour basis. The convenience of twenty-four hour availability, as well as the capability of being operated at numerous locations, where such service would otherwise not be feasible, is possible because such machines are self-operated in that they function on the command of the customerO Although such banking machines are "self-operating", the system must be accurate, error free and capable of dispensing bank notes upon command by the customer in a convenient -~-form and in quantites selected by the customer.
Many prior art bank note dispensing machines provide for the successive counting out of bank notes from a currency storage location. Others merely dispense a selected number of bills to a drawer which is subsequently opened to the customer to permit withdrawal of the currency. These systems permit selected withdrawal of varied amoùnts of currency, but do not provide an accurate method of control of the currency being paid out in that once a bank note :is dispensed there is no means of ~, .
~Z8~78 retracting the note where an error in dispensing has been made.
It will be evident that the reliability of a banking machine is of i~portance particularly when the dispenser is self-operating and unattended in any direct manner.
Considerable inconvenience may be caused to a customer if a banking machine fails to operate upon the presentation of a customer identification card as a result of a malfunction of the system.
It is also evident that only the correct quantity of bank notes should be delivered to the customer for such automatic banking machines to be acceptable. A banking machine dispensing bank notes must operate to minimize the possibility of delivering more bank notes to the customer than selected. Prior art systems utilized a "fail safe"
device that shut down the apparatus upon the detection,,of a misfeed, but such a solution causes obvious inconvenience and loss of service of the machine.
A feature of the present invention is to provide a bank note dispensing control that reliably and accurately dispenses bank notes from a storage bin to a customer at an exit throat. Individual bills are fed from the storage bin to a transport that selectively returns all but one bank note to the storage bin and transports only a single bill to an escrow station. The travel time of a bank note through the transport is monitored to detect the condition when bills are traveling together in a trailing configura-tion through the transport system. A second multiple bill evaluation is made as a bank note enters the escrow station.
Another feature of the present invention is to deliver l~Z8478 all bills in the escrow station to a customer when the correct number has been assembled. When either a trailing bill condition is detected or multiple bills are detected after completion of the timing function, all bills in the escrow station are diverted to the divert bin. This system, however, will resume normàl functioning after the divert cycle.
In accordance with one aspect of the invention there is provided a method of controlling the dispensing of bank notes from a banking machine responsive to externally generated control signals, comprising the steps of:
actuating a transport system for delivering bank notes along a transport path from a storage bin to an escrow station, detecting the movement of multiple notes along the transport path in the transport system and generating a separating signal when more than one note enters the transport system, returning all but one note in the transport system in response to the separating signal bank ~ ~-to the storage bin, timing the travel of a note past a check point displaced from the start of the transport path of the transport system to monitor for an overlapping bill condition, sensing for the presence of multiple notes traveling together through the transport system only after completion of the timing function at a location displaced downstream from the check point along the transport path by a distance such that the bank note has partially passed the location at the completion of the timing function, and transporting notes assembled at the escrow station to an exit throat.
In accordance with another aspect of the invention there is provided apparatus for controlling the dispensing -. :
~128478 of bank notes from a banking machine responsive to externally generated control signals, comprising in combination: transport means for delivering bank notes from a storage bin along a transport path to an escrow station, means responsive to multiple notes entering said transport means to return all but one note back to the storage bin, means for sensing the movement o:f a note along the transport path of said transport means to generate a note timing and note count signal, a multiple note detector located downstream of said means for sensing along the transport path by a distance less than the length of a bank note and responsive to the note timing signal to sense multiple notes traveling together through the transport means and generate a divert required signal for a multiple note condition, and means for transporting notes assembled in the escrow station to an exit throat if the multiple note detector does not sense multiple notes traveling together.
The present invention taken in conjunction with the invention disclosed in copending Canadian patent application Serial No. 301,331 which was filed on April 18, 1978 will be described in detail hereinbelow with the aid of the accompanying drawings, in which:
FIGURE 1 is a schematic of a bank note dispensing system for an automatic banking machine for delivering bank notes from storage bin to an exit throat via an escrow station;

!; , : -, Referring to FIGU~RE 1~ bank notes C on an elevator 10 , as part of a removable storage bin 12 are- delivered by means of a picker assembly 14 through a continuous belt transport 16 1 to an escrow stàtion 15. Positioning of the elevator 10 is ~ achieved by means of mechanical linkage (not shown) connected to an elevator motor 20 selectively controlled to position the bank notes C to the top of the storage bin 12 and in a position ! ~:
' to be in delivery through the sensing apparatus.
.. An optical detector 22 detects the presènce or absence ¦
. of bank notes C on the elevator 10 and provides signals to a :~ !
,~ control unit to shut down operation of the apparatus when the ,i storage bin 12 is empty of bank notes. The detector 22 includes i~
a light source 24 and a light responsive photosensor 26 for detecting the reflection of light from the light source and : ~¦ ~
20 ',. thereby determining the presence or absence of bank notes on ~ 1:
: ! the elevator 1~ hen bank notes are present on the elevator ,, 10 light emitted from the light source 24 is absorbed by the : :
bank notes and therefore undetected by the photosensor 26.
j'~ However, a portion of the elevator 10, immediately opposite ,, the light sensor 24 and the photosensor 26, includes a ninety ¦, degree included angle mirror 28 such that light emitted from ¦I the light source is reflected onto the photosensor whenever i;
I' ' .

there are no bank notes C on the elevator 10. There~ore, henever the photosensor 26 detects light as a result of the reflection from tlle mirror 28 a signal is transmitted to an ,~ external controller to shut do~.~n operation of the dispenser 1' aDparatus.
~ Control of the eIevator drive motor 20 to impart ! upward movement of the elevator lO as banl; not.es are dispensed ,~ is provided from a bill position sensor 30. Briefly, the bill ! position detector 30 includes an arm 32 supported for rotation li about a shaft 34 and attached to a vane 36. The vane 36 is ¦I positioned to move between a detector 38 comprising a light ¦~ emitting diode and a photosensor. As the bank notes C dro~
i below a predetermined level, the arm 32 and thus the vané 36 ,. rotates counterclock~ise and the detector 38 generates a signal !! to a controller for actuatin~ the elevator motor 20. In this , way, the elevator 10 is maintained in position to continuously ¦, provide bank notes for delivery to the belt transport 16.
i To deliver bank notes C from the storage bin 12 the !~ initial step is to actuate a drive motor 40 coupled to the l~ belt transport 16 by means of a drive belt 42. The main drive I' motor 40 also actuates the picker assembly 14 through a roller ¦l 44 of a separating roller pair including a roller 46. The ¦I roller 44 drives the picker assembly 14 by contact with a flat ~ ¦! belt transport 48 rotating ~ith rollers 50 and 52. Spaced l ¦ triangular sha~ed arms 54 and 56 support the rollers 50 and 52, ¦¦ respectively. The triangular shaped arm 54 rotates on a shaft 5~ and the triangular s~aped arm 56 rotates on a shaft 60 that _7_ li I

,, also supports the roller 44~ Interconnecting the triangular - ' shaped arms 54 and 56 is a linkage 62 coupled to a solenoid driver 64 through linkage arms 66 and 68. The linkage arm 66 , is pivoted about a shaft 70.
`~ To feed ban~ notes C from the elevator 10 into the , nip of the rollers 44 and 4~6, the solenoid 64 is actuated to ' rotate the picker assembly about the shafts 58 and 60 and bring the flat belt transport 48 into contact with,the bank notes.
, The flat belt transport 4S is driven in~a counterclockwise ~!1 direction and delivers bank notes in the direc-tion of the arrow i'' 72 into the nip of the rollers 44 and 46;
li :
l' A mechanical doubles de~ector 74 is mounted i~mediat21y¦
¦! downstream of the separator rollers 44 and 46 and is pos,itioned 1 such that bank notes passing through the rollers 44 and 46 in lS lll the direction of an arrow 76 pass through the double detector.
!! Also located in the area of the double detector 74 is an optical ¦I detector including a light emitting diode 78 and a photosensor ! so These elements are positioned on opposite sides of the bank !
j~ note travel path as indicated by the arrow 76. When a bank note ¦ ;
, passes into the optical detector a signal is generated to deenergize the solenoid 64.
Briefly, the doubles detector 74 lncludes a vane 82 1 pivotally mounted to rotate between a sensor 84. Motion is ;, imparted to the vane 82 when a bank note passes through detecto~ , ! rollers 86 and 88. Any movement of the vane 82 when more than one bill passes through the rollers 86 and 88 is detected by the sensor 84 that includes a light emitting diode and a "
, I , i! -8- !
1l ' .

!
! photosensor. Movement of the vane 82 by two or more bits prevents light from the diode from being detected by the photo-sensor and a signal is generated to a controller for actua-ting . clutch assemblies for selectively connecting the rollers 44 and 46 to the drive motor 40. When multiple bills are detected passing through the detector rollers ~6 and 88, the clutch for the roller 46 is energized to drive this roller backwards to , I .
i separate bills in the transport. At the same time, the clutch ~! for the roller 44 is deenergized and it is no longer driven.
, However, the roller 44 is prevented from rotating cloc~ise ¦~ (normal rotation is counterclockwise), thereby presenting the i condition that the roller 44 is nonrotating and the roller 46 j' is rotating in a counterclockwise direction. By stopping the ', roller 44 and driving the roller 46 counterclock~ise, a scrubbing 15 ii action is produced that separates bank notes that may be adhering l~ together.
~1 1 1hen the vane 82 no longer interrupts the light path ¦, of the sensor 84 the clutch for the roller 46 is deenergized 1', thereby disconnecting this roller from the drive motor 40 and 1, ii the clutch for the rQller 44 reengages the drivable connection I ~ t to the motor 40. The single bill is now driven in the direction ~j j, of the arrow 76 to the continuous belt transport 16.
¦, As illustrated, the transport 16 includes a main 'i drive roller 86 providing power to continuous belts 90 and 91, ,, each of these continuous belts moving in the path determined by jl idler rollers. For the continuous belt 91, the travel path is determined by an idler roller 92 and an idler roller 94 ~ ¦

hich also guldes a continuous belt 96 of a divert bin transport ~ 98. The roller 94 is supported on a shaft also carrying a .; pinch roller 100 that is in engagement with a pinch roller 102 , as part of an exit throat transport 104. The pinch roller 100 ' also forms a pair with a pinch roller 106 as part of the divert . bin transport 98.
` With regard to the continuous belt 90, it has a travel , path established by idler rollers 108, 110, 112 and 114, the . latter mounted on a shaft supporting a paddle wheel 116 for i, positioning a bank note in the escrow station 18.
! A bank note entering the transport 16 is driven between I., the belts 90 and 91 and subsequently passes through a detector !~ 118 comprising a light emitting diode and a photosensor. As the . bill passes through the detector 118 a slgnal is generated to 1~ deener~ize clutches driving the pinch roller 44 and the bank note is now driven only by the continuous belts 90 and 91.
Also, at this time a timing func~ion begins initiated by the ~ ~
! leading edge of a bank note passing through the detector 118.. ¦ -Il Since the length of the bank note is kno~n, the time required 1! for it to completely pass through the detector 118 may be l! calculated.~ Thus, after a preset time the bank note should have il cleared the detector 118. If a bank note is still passing through the detector 118 after this preset time interval, the ¦
j~ indication is that there is a trailing bill condition, that lS ,~
!~i a second bill is immediately follo~ing the first through the Il continuous belts 88 and 90.

l~Z8~7t3 ¦l B-6065 Il l~en the note being dis~ensed clears the detector 118, I, ¦I the pinch roller 4~ is reenergized and if the optical detector i' of diode 78 and sensor 80 is not covered, then the solenoid 64 l~ is also reenergized.
¦~ Do~nstream of the detector 118 there is located a . multiple bill detector 120~consisting of a roller 122 mounted to a pivoted arm 124 that.in turn is connected to a vane 126.
~ The vane 126 passes through a detector 128 which consists of ¦ a light emitting diode and a photosensor. As a bill passes 'I under the roller 122, it deflects the vane 126 by an amount depending on the thickness of the bill. The vane-detector ¦ relationship is such that if only one bill is passing under the , roller 122, light from the diode will be detected by the photo-¦ sensor. However, should more than one bill pass under the -I roller 122 at the same time, the vane 126 will interrupt the ~¦
! light beam to the photosensor and the detector 128 generates a double bill signal. To avoid generating a double signal from ¦ the detector 128 ~or a bill having a leading edge fold, the ¦ signal from the detector 128 is disregarded until the bank note ¦
¦ has cleared the detector 118. Thus, the multiple bill detector ¦
120 only becomes operational after a bill has cleared the I detector 118.
'I Eacll bill delivered from the storage bin 12 to the ¦ belt transport 16 exits the belt transport at the paddle wheel ¦ 116 and is assembled in the escrow station 18. The number of bills passing through the transport 16 is counted by the detector 118 and when the selected number of bills has been assembled into the escrow station 18 these bills are delivered ¦ to a customer.
I I
. l j ~28~713 ~ 6065 li At the escrow station 18, there is included a solenoid . operated gate 130 that retains the b:ills in the escrow station i during the assembly process. To properly assemble the bank !~ notes at the escrow station a leading edge paddle wheel 132 ~l rotates with the paddle wheel 116.
, Bank notes assembled in the escrow station 18 are t delivered to the exit throat transport 104 by a continuous belt ~ transport 134. This transport includes a continuous belt 136 ,~ driven by a pu112y rotating with the pinch roller 102. The !I travel path of the continuous belt 136 is further defined by j, idler pulleys 133 and 140 supported on a frame 142 that is ! rotated on a shaft 144 by means of a solenoid 146~ The solenoid I
146 is coupled to the frame 142 by means of linka~e 148..
j'. When the correct number of bills has been assembled in !
,I the escrow station 18, and they are ready to be delivered to a jl customer, a solenoid 150 is energized to rotate a divert gate 152l ¦! into a position to allow bills from the esc~ow station 18 to be ~, I; delivered to the exit throat transport 104. The divert gate 152 I is pivoted on a shaft 154 and coupled to the solenoid 150 by ll means of a linkage 156. Next, a si~nal is applied to the sole- ¦
! noid controlling the gate 130 to rotate the forward stop of the i escrow station into a bill delivery position. At the same time, I
1, a signal is applied to the solenoid 146 to rotate the continuous !
¦', belt 136 in contact with the continuous belt 91 thereby providing i, driving power for the assembled bills to be delivered to the exit !¦ throat transport 104. :¦
In the exit throat transport 104~ the bills enter ¦
a pinch roller pair consisting of the roller 102 and a roller 158,.
i' ' I
, ~128 47 8 ' i, , Also rotating with the rollers 102 and 158 are continuous belts I, 160 and 162. The continuous belt 160 rotates in the path defined~
" by idler rollers 164 and 166 while the con~inuous belt 162 , travels in a path defined by idler rollers 168 and 170.
'j As the bundle of bills from the escrow station 18 '. passes throu~h the exit throat transport 104, the bundle passes j' through-a detector 172 consisting of a light emitting diode and ' a photosensor. As the leading edge of. the bundle passes through ¦ the detector 172, a timing function is initiated. At the end of 1- the time delay a clutch controlling the operation of the roller 1! 153 is deenergized and a brake associated with this roller is energized to stop the fo~ard progress of the bundle as it moves l in the direction of the arrow 174. `1~1hen the customer removes the' ', bundle from the transport 104, the detector 172 is uncovered ', indicating that the transaction is com~lete and the system shuts i, down. I
If a double is detected at the double detector 120 or i i~ if a ~railing bill condition is sensed by the detector 118, the ¦
¦' bills assembled in the escrow station 18 are transported to a i divert bin 176. To divert bills from the escrow station 18 ¦
i' into the divert bin 176, the solenoid 150 remains deenergized ¦~ thereby holding the divert gate 152 in the position shown, the ¦~ gate 130 is rotated from its end position, and the solenoid Il 146 is energized to rotate the continuous belt 136 in contact 25 1I with the continuous belt 91.
Bills in the escrow station 18 now pass through the , pinch rollers 100 and 102 and are diverted by the gate 152 into I
!, pinch rollers 100 and 106. These bills now enter the divert bin I transport 98 which consists of, in addition to the continuous 30 ,, belt 96, a continuous belt 178. The continuous belt 96 travels ,l -13-1, 1 llZ847B
in the path established by idler rollers 1~0 and 182 while the continuous belt 178 travels in a path set by the idler roller 184.
Bills passing through the divert bin transport 98 in the direction of the arrow 188 pass through a detector 186. This detector senses when the last bill has cleared the light beam from a light emitting cliode to a photosensor and generates a signal to begirl again assembling the desired number of notes in escrow.
For a more complete description of the dispense system of FIGURE 1, reference is made to Canadian Patent No .1,095,862 of Richard C~ Hickey, which issued on February 17, 1981.
The control system of the present invention for operating the dispenser of FIGURE 1 receives basic command signals from a central controller, such controller not forming a part of the present invention. This central controller may be part of an overall banking machine that accepts inputs from a customer identifying the amount of bank notes to be dispensed. After preliminary verification checks have been made and the system is ready to dispense bank notes by the apparatlls of FIGURE 1, the central controller generates various commands to the control apparatus of the present invention.
Referring to FIGURFS 2a and 2b, there is shown circuitry for converting command signals from a central controller into control signals for the system of the present invention. Command signals from the central controller are as follows:

To ensure that the stroage bin 12 is in place as shown , i in FIGURE 1, a contact switch (not sho~) is provided. This 1~, contact switch is interconnected bet~een the terminals 296 and 1, ',¦ 29S and a contact closure provides an input to an inverter amplifier 300 at a value determined by the resistor 302 and the l~ position of the switch. The output of inverter anplifier 300 is , biased through resistor 304 and provides a status signal CASSIN5 1 indicating that the storage bin 12 is in place. The voltage ~ I

Il - Immediately downstream of the separator rollers 44 j~ and 46 is the de~ector 78 providing the signal DS4E to the input of an amplifier 324, again with input biasing circuits as described with reference to the am?lifier 232. An output of the amplifier 324 is biased through resistor 326 and applied , through an inverter amplifier 328 that generates the control i, signal DS8.
Downstream of the de~ector 11~ double bills are ,¦ detected at the multiple bill detector 123 that includes a ,,photosensor 12~ generating the signal DS9E input to an amplifier i~330 that has an output biased by a resistor 332 and applied to liinverter amplifier 334 and noninverting ampli~ier 336. Amplifier 334 drives a light source 338 and the output of the amplifier 336 is the control signal DS9.
i, Divert required (DIVR~Q5) is a status bit presented to Il,the central controller. DIVP~Q is generated by a circuit which l ~7ill be described later and is applied to the input of an ~,amplifier 340 whose second input is connected to a bias network ¦,including resistors 342 and 344 and a capacitor 346.

1, Referring to FIGURES 4a and 4~, control signals j generated by the circuitry ~of FIGUP~S 2a and 2b, and not followedl i with the logic level deslgnator 5 , are applied to timing logic to control the various control elements of the apparatus ¦¦ of FIGURE 1. There are six timing functions in the operation ¦1 of the apparatus of FIGURE l; these include;
!! 1 The length`of time a bank note is passing the ¦I detector 113, !' 2. The length of time a double note is detected at il the double detector 120, ~ `~

!i The first three of these functions require accuracy ¦ and repeatability and this is provided by a crystal oscillator ~¦ including a crystal 354 in parallel with a resistor 356 connected !~i with an inverting amplifier 35~ to form an oscillator. A

l~ith regard to the trailing bill detector 118, the ~,i amount of time it takes a bill to travel past this detector j is used to determine a trailing bill condition. This time ¦, varies with the length dimension of the bank notes in the storage, i~ bin 12 and is progra~mable by means of switch banks 368 and 370. i i! Voltages established across the resistors of these networks are input to one side of digital comparators and represent a 1,' particular count, related to note length.- Speciflcally, the Ij s~itch bank 368 connects to digital comparator 372 and the switch bank 370 connects to digital comparator 374. The count ¦
!I compared with those established by the switch bank 368 is generated in a counter 376 receiving the clock frequency through Il a gate 378. The count compared with that established by the 1i switch bank 370 is generated in a counter 380 that is inter- ¦
li connected through a gate 382 to the counter 376. The reset ,I terminal of the counters 376 and 380 receives the control signal ¦

,~ 118, the control signal DS~ is generated to remove the reset of the counters 376 and 380. These counters now accumulate ¦ `

Il ' Another timing f~mction of FIr.URES 4a and 4b is !' associated with the multiple bill detector 120. Logic for this timing function includes a counter 3~6 receiving the clock I! frequency for the amplifier 366 through a gate 388 that is also '¦
¦I connected to receive the control signal DS9 from the output of the inverter amplifier 336. Reset of the counter 386 is ,¦ controlled by the signal DS2 from the inverter am~lifier 264.

¦I The last stage of the decade counter 386 is applied ' ¦l~ to the C-terminal of a flip-flop 390-whose reset is controlled ¦I by the output of a gate 392. One input to the gate 392 is the il divert control signal DIV at the output of the inverting ¦, amplifier 214 and the second input to this gate is the motor turn on signal ,~ITRON at the output of the amplifier 204. The ¦' Q-terminal of the flip-flop 390 is connected to one input of ¦~ a divert gate 394.
ii A second input to the gate 394 is the output of a ¦~, flip-flop 396 that receives the trailing bundle control signal (T~D) from the counter 374. The reset terminal of the flip-flop 396 is tied to the output of the gate 392. Thus, ~hen either Ii . ~

Ii ~7hich causes the controller to direct the bank notes in the ~ escro~ station 18 into the divert bin 176.
.1, Another function of the timing logic of FIGURES 4a and 4b is to control energization of the solenoid 64. Logic for generating the control signal to the solenoid 64 includes li decade counters 398 and 400 connected i~ series with the clock 1, frequency at the output of the amplifier 366 applied through ,~ a gate 402 to the counter 398. The counter 398 interconnects i' to the counter 400 through a gate 404. The count accumulated in the counters 398 and 400 is controlled by a reset signal ~¦
! generated at the output of an inverter amplifier 406. This li amplifier is driven from the output of A~ID gate 408 that receives at one input the control signal b~ and has a second inpu~ connected to the output of AND gate 410. The output of 1 the AND gate 410 is a control signal L2C that controls the !
¦! clutch for the roller 44.
20 1l Input signals applied to AND gate 410 are from the output of A~D ~ate 412 and the output of an AND gate 432.
The AND gate 412 receives the control signal DS2 from the I amplifier 256 and the dispense control signal DISP from the !l amplifier 190. The AND gate 468 receives its inputs from ¦ inverter amplifier 416 whose input is the logical OR of DIV
i and DEL from gate 414 and the output of inverter 470 whose ¦
input is L3C from ~ND gate 434. The OR gate 414 receives the Il I

5 ~I to the solenoid for controlling the gate 130.
Removing the reset control from the counters 398 and 400 causes the count value of these counters to increase at the rate of the clock frequencv. When this count accumulates ,- to a defined level, a control signal Ll~ picker is applied to 10 . activate the solenoid 64 for one-quarter second, causing the ; continuous belt 48 to move to~.~7ards the first note in an effort j~ to slide it into the nip of the separating rollers 44 and 46.
l~ This action continues for one-quarte~ second or unti:L a-bank i~ ncte passes the detector 7~ ~7hich then generates a signal that 15 ,`~ reapplies the reset to the counters 398 and 400. Should a note ¦
fail to be picked, the solenoid 64 ~7ill be deactivated for one~quarter second and the process ~7ill be repeated.
!1 Another timing functiGn of the logic of FIGURES 4a 1 :
I! and 4b is provided by counters 418, 420 and 422 for controlling 20 j'i the elevator drive motor 20. The clock frequency is applied to the counter 418 through an OR gate 424 that also receives the control signal DSl from the output of the.amplifier 246.
! The last stage of the counter 418 is interconnected to the ll, counter 420 through a gate 426 and the counter 420 is inter-25 1l connected to the counter 422 through a gate 428. Each of thei reset terminals of the counters 418, 420 and 422 is controlled ¦

A second , input to the NAND gate 434 is the output of an AND gate 436 that li receives the motor control signal T~lTRON from.the inverter . , amplifier 212 and the control signal DSl from amplifier 246.
This logic circuitry controls the ener~ization of the clutch ~l associated ~ith the roller 46 for separa~ting multiple bills li when more than one bill is detected passing through the double detector 84.
ii One additional tining function of the circuitry of FIGURES 4a and 4b is control of the exit clutch and exit brake ',~ for the roller 158 Oc the exit throat transport 104. This ! timing function is controlled by logic that includes switch ;~, banks 438a and 440a with the former connected to a digital ., comparator 442 and the latter connected to a digital comparator 444. A binary number used in a co~parison in the comparator 442 li is generated at the outputs of a counter 446 and the number for l comparison in the digital com?arator 444 is genera-ted in a !i counter 448. Each of these counters is reset by the control ! signal DS4 at the output of the amplifier 282. The counter 446 ~I receives the clock frequency through a gate 450 whose other I input is connected to the output of the comparator 444. The il counters 446 and 448 are interconnected through a gate 452.

,, the clutch driving the roller 158. The output of the comparator !~ 444 is also applied to an AND gate 458 that energizes the brake 1~ for the roller 158. So long as bills remain in the detector 172, Il the exit clutch for the roller 158 remains deenergized. I
! The output of the inverter amplifier 454 also controls !
Il the reset of counters 460 and 462. The counter 460 is c-locked I a~ the frequency at the output of the amplifier 366 through a !i gate 464 with the counters interconnected through a gate 466.
I~rnen the reset is removed from the counters 460 and 462 they ¦~ count up at the clock frequency rate. After a preset time, a I~ control signal is generated from the counter 462 to inhibit ¦, the clock frequency from the counters 460 and 462 and also ¦I deenergize the exit brake of the roller 158 through an inverter amplifier 468 having an output connected to the AND gate 458.
As the customer removes the bundle from the area of , the detector 174, the reset signal is again applied to the I counters 446 and 448 and the exit clutch is again energized to 5 1, drive the roller 158.
ith the control system of the present invention, ban~ notes are dispensed from the storage bin 12 by first ,: .

¦, If a trailing bill condition is detected or a multiple bill condition is detected, the bank notes assembled in the escrow station 18 are diverted into the divert bin 176-by an e~.ternal controller.

That is, that there are no bank notes in the escrow station 18~ in the exit throat transport 104 or ,1 in the divert bin transport 98. Further, a dispense cycle ~t cannot begin unless there are bills on the elevator 10 as ,' determined by the detector 22. Also, the storage bin 12 must 15 ,~ be in place before a dispense cycle begins. ;
During the dispensing of bank notes, multiple bills ~ traveling together are detected at the multiple bill detector 84 ~' -!' and at the multiple bill detector 120. Trailing bills are ¦

This invention relates to a banking machine, and more particularly to apparatus and the method of controlling the dispensing of bank notes from a banking machine.
Recent studies have shown that the general public is relying more heavily on the use of automatic banking machines to complete their financial transactions. There are many reasons advanced for this change from conventional banking for completing financial transactions to the use of automatic banking machines. One significant advantage, however, of the automatic banking machine is its availability on a twenty-four hour basis. The convenience of twenty-four hour availability, as well as the capability of being operated at numerous locations, where such service would otherwise not be feasible, is possible because such machines are self-operated in that they function on the command of the customerO Although such banking machines are "self-operating", the system must be accurate, error free and capable of dispensing bank notes upon command by the customer in a convenient -~-form and in quantites selected by the customer.
Many prior art bank note dispensing machines provide for the successive counting out of bank notes from a currency storage location. Others merely dispense a selected number of bills to a drawer which is subsequently opened to the customer to permit withdrawal of the currency. These systems permit selected withdrawal of varied amoùnts of currency, but do not provide an accurate method of control of the currency being paid out in that once a bank note :is dispensed there is no means of ~, .
~Z8~78 retracting the note where an error in dispensing has been made.
It will be evident that the reliability of a banking machine is of i~portance particularly when the dispenser is self-operating and unattended in any direct manner.
Considerable inconvenience may be caused to a customer if a banking machine fails to operate upon the presentation of a customer identification card as a result of a malfunction of the system.
It is also evident that only the correct quantity of bank notes should be delivered to the customer for such automatic banking machines to be acceptable. A banking machine dispensing bank notes must operate to minimize the possibility of delivering more bank notes to the customer than selected. Prior art systems utilized a "fail safe"
device that shut down the apparatus upon the detection,,of a misfeed, but such a solution causes obvious inconvenience and loss of service of the machine.
A feature of the present invention is to provide a bank note dispensing control that reliably and accurately dispenses bank notes from a storage bin to a customer at an exit throat. Individual bills are fed from the storage bin to a transport that selectively returns all but one bank note to the storage bin and transports only a single bill to an escrow station. The travel time of a bank note through the transport is monitored to detect the condition when bills are traveling together in a trailing configura-tion through the transport system. A second multiple bill evaluation is made as a bank note enters the escrow station.
Another feature of the present invention is to deliver l~Z8478 all bills in the escrow station to a customer when the correct number has been assembled. When either a trailing bill condition is detected or multiple bills are detected after completion of the timing function, all bills in the escrow station are diverted to the divert bin. This system, however, will resume normàl functioning after the divert cycle.
In accordance with one aspect of the invention there is provided a method of controlling the dispensing of bank notes from a banking machine responsive to externally generated control signals, comprising the steps of:
actuating a transport system for delivering bank notes along a transport path from a storage bin to an escrow station, detecting the movement of multiple notes along the transport path in the transport system and generating a separating signal when more than one note enters the transport system, returning all but one note in the transport system in response to the separating signal bank ~ ~-to the storage bin, timing the travel of a note past a check point displaced from the start of the transport path of the transport system to monitor for an overlapping bill condition, sensing for the presence of multiple notes traveling together through the transport system only after completion of the timing function at a location displaced downstream from the check point along the transport path by a distance such that the bank note has partially passed the location at the completion of the timing function, and transporting notes assembled at the escrow station to an exit throat.
In accordance with another aspect of the invention there is provided apparatus for controlling the dispensing -. :
~128478 of bank notes from a banking machine responsive to externally generated control signals, comprising in combination: transport means for delivering bank notes from a storage bin along a transport path to an escrow station, means responsive to multiple notes entering said transport means to return all but one note back to the storage bin, means for sensing the movement o:f a note along the transport path of said transport means to generate a note timing and note count signal, a multiple note detector located downstream of said means for sensing along the transport path by a distance less than the length of a bank note and responsive to the note timing signal to sense multiple notes traveling together through the transport means and generate a divert required signal for a multiple note condition, and means for transporting notes assembled in the escrow station to an exit throat if the multiple note detector does not sense multiple notes traveling together.
The present invention taken in conjunction with the invention disclosed in copending Canadian patent application Serial No. 301,331 which was filed on April 18, 1978 will be described in detail hereinbelow with the aid of the accompanying drawings, in which:
FIGURE 1 is a schematic of a bank note dispensing system for an automatic banking machine for delivering bank notes from storage bin to an exit throat via an escrow station;

!; , : -, Referring to FIGU~RE 1~ bank notes C on an elevator 10 , as part of a removable storage bin 12 are- delivered by means of a picker assembly 14 through a continuous belt transport 16 1 to an escrow stàtion 15. Positioning of the elevator 10 is ~ achieved by means of mechanical linkage (not shown) connected to an elevator motor 20 selectively controlled to position the bank notes C to the top of the storage bin 12 and in a position ! ~:
' to be in delivery through the sensing apparatus.
.. An optical detector 22 detects the presènce or absence ¦
. of bank notes C on the elevator 10 and provides signals to a :~ !
,~ control unit to shut down operation of the apparatus when the ,i storage bin 12 is empty of bank notes. The detector 22 includes i~
a light source 24 and a light responsive photosensor 26 for detecting the reflection of light from the light source and : ~¦ ~

bank notes and therefore undetected by the photosensor 26.
j'~ However, a portion of the elevator 10, immediately opposite ,, the light sensor 24 and the photosensor 26, includes a ninety ¦, degree included angle mirror 28 such that light emitted from ¦I the light source is reflected onto the photosensor whenever i;

there are no bank notes C on the elevator 10. There~ore, henever the photosensor 26 detects light as a result of the reflection from tlle mirror 28 a signal is transmitted to an ,~ external controller to shut do~.~n operation of the dispenser 1' aDparatus.
~ Control of the eIevator drive motor 20 to impart ! upward movement of the elevator lO as banl; not.es are dispensed ,~ is provided from a bill position sensor 30. Briefly, the bill ! position detector 30 includes an arm 32 supported for rotation li about a shaft 34 and attached to a vane 36. The vane 36 is ¦I positioned to move between a detector 38 comprising a light ¦~ emitting diode and a photosensor. As the bank notes C dro~
i below a predetermined level, the arm 32 and thus the vané 36 ,. rotates counterclock~ise and the detector 38 generates a signal !! to a controller for actuatin~ the elevator motor 20. In this , way, the elevator 10 is maintained in position to continuously ¦, provide bank notes for delivery to the belt transport 16.
i To deliver bank notes C from the storage bin 12 the !~ initial step is to actuate a drive motor 40 coupled to the l~ belt transport 16 by means of a drive belt 42. The main drive I' motor 40 also actuates the picker assembly 14 through a roller ¦l 44 of a separating roller pair including a roller 46. The ¦I roller 44 drives the picker assembly 14 by contact with a flat ~ ¦! belt transport 48 rotating ~ith rollers 50 and 52. Spaced l ¦ triangular sha~ed arms 54 and 56 support the rollers 50 and 52, ¦¦ respectively. The triangular shaped arm 54 rotates on a shaft 5~ and the triangular s~aped arm 56 rotates on a shaft 60 that _7_ li I

,, also supports the roller 44~ Interconnecting the triangular - ' shaped arms 54 and 56 is a linkage 62 coupled to a solenoid driver 64 through linkage arms 66 and 68. The linkage arm 66 , is pivoted about a shaft 70.
`~ To feed ban~ notes C from the elevator 10 into the , nip of the rollers 44 and 4~6, the solenoid 64 is actuated to ' rotate the picker assembly about the shafts 58 and 60 and bring the flat belt transport 48 into contact with,the bank notes.
, The flat belt transport 4S is driven in~a counterclockwise ~!1 direction and delivers bank notes in the direc-tion of the arrow i'' 72 into the nip of the rollers 44 and 46;
li :
l' A mechanical doubles de~ector 74 is mounted i~mediat21y¦
¦! downstream of the separator rollers 44 and 46 and is pos,itioned 1 such that bank notes passing through the rollers 44 and 46 in lS lll the direction of an arrow 76 pass through the double detector.
!! Also located in the area of the double detector 74 is an optical ¦I detector including a light emitting diode 78 and a photosensor ! so These elements are positioned on opposite sides of the bank !
j~ note travel path as indicated by the arrow 76. When a bank note ¦ ;
, passes into the optical detector a signal is generated to deenergize the solenoid 64.
Briefly, the doubles detector 74 lncludes a vane 82 1 pivotally mounted to rotate between a sensor 84. Motion is ;, imparted to the vane 82 when a bank note passes through detecto~ , ! rollers 86 and 88. Any movement of the vane 82 when more than one bill passes through the rollers 86 and 88 is detected by the sensor 84 that includes a light emitting diode and a "

! photosensor. Movement of the vane 82 by two or more bits prevents light from the diode from being detected by the photo-sensor and a signal is generated to a controller for actua-ting . clutch assemblies for selectively connecting the rollers 44 and 46 to the drive motor 40. When multiple bills are detected passing through the detector rollers ~6 and 88, the clutch for the roller 46 is energized to drive this roller backwards to , I .
i separate bills in the transport. At the same time, the clutch ~! for the roller 44 is deenergized and it is no longer driven.
, However, the roller 44 is prevented from rotating cloc~ise ¦~ (normal rotation is counterclockwise), thereby presenting the i condition that the roller 44 is nonrotating and the roller 46 j' is rotating in a counterclockwise direction. By stopping the ', roller 44 and driving the roller 46 counterclock~ise, a scrubbing 15 ii action is produced that separates bank notes that may be adhering l~ together.
~1 1 1hen the vane 82 no longer interrupts the light path ¦, of the sensor 84 the clutch for the roller 46 is deenergized 1', thereby disconnecting this roller from the drive motor 40 and 1, ii the clutch for the rQller 44 reengages the drivable connection I ~ t to the motor 40. The single bill is now driven in the direction ~j j, of the arrow 76 to the continuous belt transport 16.
¦, As illustrated, the transport 16 includes a main 'i drive roller 86 providing power to continuous belts 90 and 91, ,, each of these continuous belts moving in the path determined by jl idler rollers. For the continuous belt 91, the travel path is determined by an idler roller 92 and an idler roller 94 ~ ¦

The roller 94 is supported on a shaft also carrying a .; pinch roller 100 that is in engagement with a pinch roller 102 , as part of an exit throat transport 104. The pinch roller 100 ' also forms a pair with a pinch roller 106 as part of the divert . bin transport 98.
` With regard to the continuous belt 90, it has a travel , path established by idler rollers 108, 110, 112 and 114, the . latter mounted on a shaft supporting a paddle wheel 116 for i, positioning a bank note in the escrow station 18.
! A bank note entering the transport 16 is driven between I., the belts 90 and 91 and subsequently passes through a detector !~ 118 comprising a light emitting diode and a photosensor. As the . bill passes through the detector 118 a slgnal is generated to 1~ deener~ize clutches driving the pinch roller 44 and the bank note is now driven only by the continuous belts 90 and 91.
Also, at this time a timing func~ion begins initiated by the ~ ~
! leading edge of a bank note passing through the detector 118.. ¦ -Il Since the length of the bank note is kno~n, the time required 1! for it to completely pass through the detector 118 may be l! calculated.~ Thus, after a preset time the bank note should have il cleared the detector 118. If a bank note is still passing through the detector 118 after this preset time interval, the ¦
j~ indication is that there is a trailing bill condition, that lS ,~
!~i a second bill is immediately follo~ing the first through the Il continuous belts 88 and 90.

¦~ Do~nstream of the detector 118 there is located a . multiple bill detector 120~consisting of a roller 122 mounted to a pivoted arm 124 that.in turn is connected to a vane 126.
~ The vane 126 passes through a detector 128 which consists of ¦ a light emitting diode and a photosensor. As a bill passes 'I under the roller 122, it deflects the vane 126 by an amount depending on the thickness of the bill. The vane-detector ¦ relationship is such that if only one bill is passing under the , roller 122, light from the diode will be detected by the photo-¦ sensor. However, should more than one bill pass under the -I roller 122 at the same time, the vane 126 will interrupt the ~¦
! light beam to the photosensor and the detector 128 generates a double bill signal. To avoid generating a double signal from ¦ the detector 128 ~or a bill having a leading edge fold, the ¦ signal from the detector 128 is disregarded until the bank note ¦
¦ has cleared the detector 118. Thus, the multiple bill detector ¦
120 only becomes operational after a bill has cleared the I detector 118.
'I Eacll bill delivered from the storage bin 12 to the ¦ belt transport 16 exits the belt transport at the paddle wheel ¦ 116 and is assembled in the escrow station 18. The number of bills passing through the transport 16 is counted by the detector 118 and when the selected number of bills has been assembled into the escrow station 18 these bills are delivered ¦ to a customer.

. l j ~28~713 ~ 6065 li At the escrow station 18, there is included a solenoid . operated gate 130 that retains the b:ills in the escrow station i during the assembly process. To properly assemble the bank !~ notes at the escrow station a leading edge paddle wheel 132 ~l rotates with the paddle wheel 116.
, Bank notes assembled in the escrow station 18 are t delivered to the exit throat transport 104 by a continuous belt ~ transport 134. This transport includes a continuous belt 136 ,~ driven by a pu112y rotating with the pinch roller 102. The !I travel path of the continuous belt 136 is further defined by j, idler pulleys 133 and 140 supported on a frame 142 that is ! rotated on a shaft 144 by means of a solenoid 146~ The solenoid I
146 is coupled to the frame 142 by means of linka~e 148..
j'. When the correct number of bills has been assembled in !
,I the escrow station 18, and they are ready to be delivered to a jl customer, a solenoid 150 is energized to rotate a divert gate 152l ¦! into a position to allow bills from the esc~ow station 18 to be ~, I; delivered to the exit throat transport 104. The divert gate 152 I is pivoted on a shaft 154 and coupled to the solenoid 150 by ll means of a linkage 156. Next, a si~nal is applied to the sole- ¦
! noid controlling the gate 130 to rotate the forward stop of the i escrow station into a bill delivery position. At the same time, I
1, a signal is applied to the solenoid 146 to rotate the continuous !
¦', belt 136 in contact with the continuous belt 91 thereby providing i, driving power for the assembled bills to be delivered to the exit !¦ throat transport 104. :¦
In the exit throat transport 104~ the bills enter ¦
a pinch roller pair consisting of the roller 102 and a roller 158,.
i' ' I
, ~128 47 8 ' i, , Also rotating with the rollers 102 and 158 are continuous belts I, 160 and 162. The continuous belt 160 rotates in the path defined~
" by idler rollers 164 and 166 while the con~inuous belt 162 , travels in a path defined by idler rollers 168 and 170.
'j As the bundle of bills from the escrow station 18 '. passes throu~h the exit throat transport 104, the bundle passes j' through-a detector 172 consisting of a light emitting diode and ' a photosensor. As the leading edge of. the bundle passes through ¦ the detector 172, a timing function is initiated. At the end of 1- the time delay a clutch controlling the operation of the roller 1! 153 is deenergized and a brake associated with this roller is energized to stop the fo~ard progress of the bundle as it moves l in the direction of the arrow 174. `1~1hen the customer removes the' ', bundle from the transport 104, the detector 172 is uncovered ', indicating that the transaction is com~lete and the system shuts i, down. I
If a double is detected at the double detector 120 or i i~ if a ~railing bill condition is sensed by the detector 118, the ¦
¦' bills assembled in the escrow station 18 are transported to a i divert bin 176. To divert bills from the escrow station 18 ¦
i' into the divert bin 176, the solenoid 150 remains deenergized ¦~ thereby holding the divert gate 152 in the position shown, the ¦~ gate 130 is rotated from its end position, and the solenoid Il 146 is energized to rotate the continuous belt 136 in contact 25 1I with the continuous belt 91.
Bills in the escrow station 18 now pass through the , pinch rollers 100 and 102 and are diverted by the gate 152 into I
!, pinch rollers 100 and 106. These bills now enter the divert bin I transport 98 which consists of, in addition to the continuous 30 ,, belt 96, a continuous belt 178. The continuous belt 96 travels ,l -13-1, 1 llZ847B
in the path established by idler rollers 1~0 and 182 while the continuous belt 178 travels in a path set by the idler roller 184.
Bills passing through the divert bin transport 98 in the direction of the arrow 188 pass through a detector 186. This detector senses when the last bill has cleared the light beam from a light emitting cliode to a photosensor and generates a signal to begirl again assembling the desired number of notes in escrow.
For a more complete description of the dispense system of FIGURE 1, reference is made to Canadian Patent No .1,095,862 of Richard C~ Hickey, which issued on February 17, 1981.

1, Referring to FIGURES 4a and 4~, control signals j generated by the circuitry ~of FIGUP~S 2a and 2b, and not followedl i with the logic level deslgnator 5 , are applied to timing logic to control the various control elements of the apparatus ¦¦ of FIGURE 1. There are six timing functions in the operation ¦1 of the apparatus of FIGURE l; these include;
!! 1 The length`of time a bank note is passing the ¦I detector 113, !' 2. The length of time a double note is detected at il the double detector 120, ~ `~
1 3, The time required to deliver a bundl.e of notes - ! from the detector 172 to the exit throat, 1 4. The length of time that the brake is energized i for the roller 158, 5. The time for scrubbing action produced by the I rollers 44 and 46, and ¦ 6. Controlling the energization of the solenoid 64.
!i The first three of these functions require accuracy ¦ and repeatability and this is provided by a crystal oscillator ~¦ including a crystal 354 in parallel with a resistor 356 connected !~i with an inverting amplifier 35~ to form an oscillator. A

,j The output frequency of the amplifier 366 may typically be ~00 I) Hz. This frequency signal is the clock applied to various timing networks of the control systern of the present invention.
l~ith regard to the trailing bill detector 118, the ~,i amount of time it takes a bill to travel past this detector j is used to determine a trailing bill condition. This time ¦, varies with the length dimension of the bank notes in the storage, i~ bin 12 and is progra~mable by means of switch banks 368 and 370. i i! Voltages established across the resistors of these networks are input to one side of digital comparators and represent a 1,' particular count, related to note length.- Speciflcally, the Ij s~itch bank 368 connects to digital comparator 372 and the switch bank 370 connects to digital comparator 374. The count ¦
!I compared with those established by the switch bank 368 is generated in a counter 376 receiving the clock frequency through Il a gate 378. The count compared with that established by the 1i switch bank 370 is generated in a counter 380 that is inter- ¦
li connected through a gate 382 to the counter 376. The reset ,I terminal of the counters 376 and 380 receives the control signal ¦
,~ DS2 from the output of the inverter amplifier 256.
I! As the leading edge of a bank note enters the detector ¦
,~ 118, the control signal DS~ is generated to remove the reset of the counters 376 and 380. These counters now accumulate ¦ `
a count signal at the clock frequency generated at the output of the inverter amplifier 366. The accumulated count continues ;

The trailing bill divert signal is used to subsequently produce a divert required status signal, requesting that the controller divert bills assembled ,~

Il ' Another timing f~mction of FIr.URES 4a and 4b is !' associated with the multiple bill detector 120. Logic for this timing function includes a counter 3~6 receiving the clock I! frequency for the amplifier 366 through a gate 388 that is also '¦
¦I connected to receive the control signal DS9 from the output of the inverter amplifier 336. Reset of the counter 386 is ,¦ controlled by the signal DS2 from the inverter am~lifier 264.

¦I The last stage of the decade counter 386 is applied ' ¦l~ to the C-terminal of a flip-flop 390-whose reset is controlled ¦I by the output of a gate 392. One input to the gate 392 is the il divert control signal DIV at the output of the inverting ¦, amplifier 214 and the second input to this gate is the motor turn on signal ,~ITRON at the output of the amplifier 204. The ¦' Q-terminal of the flip-flop 390 is connected to one input of ¦~ a divert gate 394.
ii A second input to the gate 394 is the output of a ¦~, flip-flop 396 that receives the trailing bundle control signal (T~D) from the counter 374. The reset terminal of the flip-flop 396 is tied to the output of the gate 392. Thus, ~hen either Ii . ~

, is used to produce the DIVREQ5 status signal previously discussed~
Ii ~7hich causes the controller to direct the bank notes in the ~ escro~ station 18 into the divert bin 176.
.1, Another function of the timing logic of FIGURES 4a and 4b is to control energization of the solenoid 64. Logic for generating the control signal to the solenoid 64 includes li decade counters 398 and 400 connected i~ series with the clock 1, frequency at the output of the amplifier 366 applied through ,~ a gate 402 to the counter 398. The counter 398 interconnects i' to the counter 400 through a gate 404. The count accumulated in the counters 398 and 400 is controlled by a reset signal ~¦
! generated at the output of an inverter amplifier 406. This li amplifier is driven from the output of A~ID gate 408 that receives at one input the control signal b~ and has a second inpu~ connected to the output of AND gate 410. The output of 1 the AND gate 410 is a control signal L2C that controls the !
¦! clutch for the roller 44.
20 1l Input signals applied to AND gate 410 are from the output of A~D ~ate 412 and the output of an AND gate 432.
The AND gate 412 receives the control signal DS2 from the I amplifier 256 and the dispense control signal DISP from the !l amplifier 190. The AND gate 468 receives its inputs from ¦ inverter amplifier 416 whose input is the logical OR of DIV
i and DEL from gate 414 and the output of inverter 470 whose ¦
input is L3C from ~ND gate 434. The OR gate 414 receives the Il I

divert control signal DIV from the ~plifier 214 and i~he bundle . deliver signal DEL from the output of the amplifier 196. The .. output of the OP~ gate 414 is also the control voltage L4C for " energizing the solenoid 146 and the control voltage L9C applied I
5 ~I to the solenoid for controlling the gate 130.
Removing the reset control from the counters 398 and 400 causes the count value of these counters to increase at the rate of the clock frequencv. When this count accumulates ,- to a defined level, a control signal Ll~ picker is applied to 10 . activate the solenoid 64 for one-quarter second, causing the ; continuous belt 48 to move to~.~7ards the first note in an effort j~ to slide it into the nip of the separating rollers 44 and 46.
l~ This action continues for one-quarte~ second or unti:L a-bank i~ ncte passes the detector 7~ ~7hich then generates a signal that 15 ,`~ reapplies the reset to the counters 398 and 400. Should a note ¦
fail to be picked, the solenoid 64 ~7ill be deactivated for one~quarter second and the process ~7ill be repeated.
!1 Another timing functiGn of the logic of FIGURES 4a 1 :
I! and 4b is provided by counters 418, 420 and 422 for controlling 20 j'i the elevator drive motor 20. The clock frequency is applied to the counter 418 through an OR gate 424 that also receives the control signal DSl from the output of the.amplifier 246.
! The last stage of the counter 418 is interconnected to the ll, counter 420 through a gate 426 and the counter 420 is inter-25 1l connected to the counter 422 through a gate 428. Each of thei reset terminals of the counters 418, 420 and 422 is controlled ¦
¦ by the output of an OR gate 430. Gate 430 receives the motor ll l !, !

i, The output of the counter 422 is applied through an i~ inverter amplifier 432 to the input of a NAND gate 434. A second , input to the NAND gate 434 is the output of an AND gate 436 that li receives the motor control signal T~lTRON from.the inverter . , amplifier 212 and the control signal DSl from amplifier 246.
This logic circuitry controls the ener~ization of the clutch ~l associated ~ith the roller 46 for separa~ting multiple bills li when more than one bill is detected passing through the double detector 84.
ii One additional tining function of the circuitry of FIGURES 4a and 4b is control of the exit clutch and exit brake ',~ for the roller 158 Oc the exit throat transport 104. This ! timing function is controlled by logic that includes switch ;~, banks 438a and 440a with the former connected to a digital ., comparator 442 and the latter connected to a digital comparator 444. A binary number used in a co~parison in the comparator 442 li is generated at the outputs of a counter 446 and the number for l comparison in the digital com?arator 444 is genera-ted in a !i counter 448. Each of these counters is reset by the control ! signal DS4 at the output of the amplifier 282. The counter 446 ~I receives the clock frequency through a gate 450 whose other I input is connected to the output of the comparator 444. The il counters 446 and 448 are interconnected through a gate 452.

i applied to the counters ~46 and 448 is removed and these countersj i respond to the clock frequency to generate an increasing binary i number. This binary number is compared in the digital I, comparators 442 and 444. I~en the count in the counters 446 ~ and 448 equals a value set by the switch banks 43&a and 440a i' an output from the comparator 4~2 is applied through an inverter !
! a~plifier 454 that triggers an A~ID gate 456 thereby deenergizing¦
,, the clutch driving the roller 158. The output of the comparator !~ 444 is also applied to an AND gate 458 that energizes the brake 1~ for the roller 158. So long as bills remain in the detector 172, Il the exit clutch for the roller 158 remains deenergized. I
! The output of the inverter amplifier 454 also controls !
Il the reset of counters 460 and 462. The counter 460 is c-locked I a~ the frequency at the output of the amplifier 366 through a !i gate 464 with the counters interconnected through a gate 466.
I~rnen the reset is removed from the counters 460 and 462 they ¦~ count up at the clock frequency rate. After a preset time, a I~ control signal is generated from the counter 462 to inhibit ¦, the clock frequency from the counters 460 and 462 and also ¦I deenergize the exit brake of the roller 158 through an inverter amplifier 468 having an output connected to the AND gate 458.
As the customer removes the bundle from the area of , the detector 174, the reset signal is again applied to the I counters 446 and 448 and the exit clutch is again energized to 5 1, drive the roller 158.
ith the control system of the present invention, ban~ notes are dispensed from the storage bin 12 by first ,: .

~-6065 --turning on the motor 40 to transport bills from the storage bin 'j to the escrow station 18. After the correct nu~ber of bank notes ' has been assembled at the escrow station 18 they are delivered ~ to the exit throat by means of the e~it throat transport 104.
¦, If a trailing bill condition is detected or a multiple bill condition is detected, the bank notes assembled in the escrow station 18 are diverted into the divert bin 176-by an e~.ternal controller. To restart a subsequent cycle, signals generated . by the detectors 119, 172 and 186 must indicate that no bank ,' notes are in these areas. That is, that there are no bank notes in the escrow station 18~ in the exit throat transport 104 or ,1 in the divert bin transport 98. Further, a dispense cycle ~t cannot begin unless there are bills on the elevator 10 as ,' determined by the detector 22. Also, the storage bin 12 must 15 ,~ be in place before a dispense cycle begins. ;
During the dispensing of bank notes, multiple bills ~ traveling together are detected at the multiple bill detector 84 ~' -!' and at the multiple bill detector 120. Trailing bills are ¦
i, sensed at the detector llB. Each of these functions ensures the i~
