## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims benefit pursuant to 35 U.S.C. §119(e) of Provisional Application 60/702,197 filed Jul. 25, 2005


TECHNICAL FIELD
This invention relates to automated transaction machines. Specifically, the invention relates to an automated transaction machine capable of monitoring movement of a gate controlling access through an opening in the housing of the automated banking machine.
BACKGROUND ART
Automated transaction machines are known in the prior art. A common type of automated transaction machine is an automated teller machine (ATM). ATMs have been developed which are capable of performing a variety of transactions including the dispensing of currency notes. ATMs are commonly used by individuals to receive cash from their accounts, to pay bills, to transfer cash between accounts, and to make deposits. Certain ATMs also have the capability of delivering and receiving various types of sheet materials. For example, some ATMs dispense materials such as tickets, travelers' checks, money orders, bank checks, scrip, stamps, vouchers, gaming materials, lottery tickets, transit tokens, or other sheet materials stored in or produced by the machine. Other types of transaction machines dispense notes which are alternatively referred to herein as bills, and other types of sheets to users such as bank tellers, cashiers, and other service providers. Automated transaction machines generally dispense such materials while operating to enable appropriate charges and credits to be applied to the respective accounts of the customer, the machine owner, and/or the provider of the dispensed materials. For purposes of this description an automated transaction machine, automated banking machine or ATM will be considered as any machine that carries out transactions including transfers of value.
Customers also commonly receive from an ATM a printed sheet which is a receipt indicating the particulars of the transactions they have conducted at the machine. In addition customers may request and receive from some ATMs a more detailed statement of transactions conducted on their account.
ATMs currently in use often have different areas on the machine where sheets are received from or delivered to a customer. For example, most machines include one area for delivering bills to a customer and another area for receiving deposits.
ATMs that dispense currency bills or other types of sheets representative of value are generally constructed to prevent unauthorized persons from accessing the supply of sheets held inside the machine. ATMs typically include a generally secure chest or enclosure. The interior of the enclosure includes storage areas for currency bills and other types of sheet materials. ATMs may include several different passageways, devices and transports which operate to deliver sheet materials from storage areas in the machine to users.
Unfortunately, some unscrupulous individuals on rare occasions are successful in tampering with ATMs. Sometimes this is done by placing objects through a sheet delivery opening. Such tampering may corrupt the operation of the machine and prevent the final delivery of sheet materials to the customer. Therefore, a customer's account may be charged the value of the requested sheet materials without the customer ever receiving the sheet materials. In some cases, such unscrupulous individuals may return to the ATM after the sheets of an authorized user have become trapped inside the machine near the delivery opening and attempt to extract them.
In many ATMs, access through the sheet delivery opening is controlled by a movable gate. In normal operation of the ATM, the gate may be controlled to move to open the delivery opening when the requested sheet material is ready to be presented to the customer. The gate may be constructed so that when the sheet material that is presented to the user is removed, the gate returns to a closed position.
In instances of tampering when sheets are being presented, the unscrupulous individual may move the gate to place objects inside the ATM through the opening. Such objects may trap bills that one or more users may subsequently request the ATM to dispense. At a later time, the unscrupulous individual may return and reopen the gate to extract any trapped bills. The fact that protective gates must open to at least provide access to the ATM interior during a legitimate transaction presents a potential way for criminals to try to attack the machine.
Thus, there exists a need for an automated transaction machine that reduces the risk of machine tampering.

The controller is operative to carry out programmed instructions to achieve operation of the machine in accomplishing transactions. As schematically indicated, the controller is in operative connection with a plurality of the transaction function devices included in the machine.
The exemplary embodiment of the ATM includes at least one communication device 26. The communications device may be one or more of a plurality of types of devices that enable the machine to communicate with remote computers and other systems and devices for purposes of carrying out transactions. For example, communications device 26 may include a modem for communicating messages over a data line or wireless network, with one or more other computers that operate to transfer data representative of the transfer of funds in response to transactions conducted at the machine. Alternately the communications device 26 may include various types of network interfaces, line drivers or other devices suitable to enable communication between the machine 10 and other computers and systems. Embodiments may also include features described in U.S. Pat. No. 7,003,492, which is incorporated herein by reference.
Machine 10 also includes a plurality of sensing devices for sensing various conditions in the machine. These various sensing devices are represented schematically by component 28 for simplicity and to facilitate understanding. It should be understood that a plurality of sensing devices are provided in the machine for sensing and indicating to the controller 22 the status of devices within the machine. Various types of sensing devices may generate analog and/or digital signals that correspond to sensed properties such as, for example, displacement, time, speed, acceleration and/or other measurable properties. In accordance with an exemplary embodiment, the operation of at least one exemplary sensing device is discussed in further detail below.
Automated banking machine 10 further includes a plurality of actuators schematically indicated 30 and 32. The actuators may comprise a plurality of devices such as motors, solenoids, cylinders, rotary actuators and other types of devices that are operative responsive to the controller 22.

In accordance with the invention, the operation of at least one actuator is disclosed in further detail below.
Machine 10 may also include in image capture device 34. Image capture device 34 may be operative to capture images of portions of a user. For example, images of the user's face may be captured for purposes of making records related to a transaction. Alternately, images of a user's face may be analyzed and used for purposes of identifying the user. In an exemplary embodiment, the image capture device 34 may be used to capture at least one image of an unauthorized user of the machine 10 in response to the indication of a suspect condition as will be explained in further detail below. Embodiments may include features described in U.S. Pat. No. 6,583,813, which is incorporated herein by reference.
In an exemplary embodiment, machine 10 may further include an alarm mechanism 36 that may be activated in response to the indication of a suspect condition. Additionally, communications device 26 may be utilized in a manner described below to alert persons at a remote location that a suspect condition has been indicated at machine 10.
Machine 10 further comprises at least one currency dispenser mechanism 38. The currency dispensing mechanism is operative responsive to the controller 22 to pick sheets and deliver them to a user through an opening 68 in the ATM housing. Sheets may be selectively picked by a picker mechanism 40 generally one at a time from a stack of sheets such as stack 42. In the exemplary embodiment, the stack of sheets is stored in a cassette 44. As schematically represented, the stack of sheets 42 is biased to engage the picker mechanism 40 by a biasing mechanism 52.
Notes that are dispensed from the cassette in the exemplary embodiment are engaged with a first note transport schematically indicated 54. Sheets dispensed from cassette 44 are enabled to engage the adjacent flights of belts and move in engagement therewith upward to a second transport 60. First note transport may be similar to that shown in U.S. Pat. No. 5,240,368, U.S. Pat. No. 6,484,380, or U.S. Pat. No. 6,315,194 the disclosures of which are incorporated by reference as if fully rewritten herein
The second transport 60 in the exemplary embodiment may be similar to that shown in U.S. Pat. No. 5,240,368, U.S. Pat. No. 5,342,165, or U.S. Pat. No. 6,315,194 the disclosures of which are incorporated by reference as if fully rewritten herein. In response to operation of the controller 22 when a desired number of sheets have been collected in a stack 66 in a delivery position, the stack is moved in the manner of the incorporated disclosures so that stack 66 is moved outward toward the opening 68 in the housing 12 of the machine.
As the sheets are moved toward the opening 68, the controller operates to cause a suitable actuating device to operate a gate assembly 70 and move at least one gate thereof from a closed position to an open position so as to enable the stack to pass outward through the user opening. The exemplary transport stops with the stack extending outward from the opening. As a result the user is enabled to receive the sheets from the machine.
With reference to FIGS. 1 and 2, in the exemplary embodiment, gate assembly 70 is supported at a delivery end of second note transport 60. In the exemplary embodiment, gate assembly 70 includes a gate member 74, which is alternatively referred to as a gate. One or more biasing members 76, which in the exemplary embodiment comprise springs, pivotally urge gate member 74 toward a closed condition blocking the opening, and one or more biasing members 78 laterally urge gate member 74 toward the closed condition. Gate pivot member 80 is operably associated with an actuator 84. Actuator 84 is operative responsive to operation of the controller to move gate member 74 from the closed position to an open condition when a stack 66 in the delivery position is moved outward to present to a user. Of course this approach is exemplary.
In the exemplary embodiment, the gate member is operably associated with an analog sensor 85 which senses the position of the gate relative to the closed position based on the position of pivot member 80. In the exemplary embodiment, sensor 85 includes a movable finger 87 which engages gate pivot member 80 and provides at least one signal that corresponds to a current position of gate member 74. Of course signals produced by the sensor may be based on a reference other than the closed position, which in some embodiments may include a fixed or a variable reference.
During normal operation of the gate assembly, actuator 84 moves pivot member 80 laterally, which causes pivotal movement to open gate member 74. In a normal operation, the gate member 74 will be vertically and pivotally displaced from the closed position to the open position to enable a portion of stack 66 to move outward past the gate, so it may be taken by a user. Once the stack is sensed as extended through the opening, the controller operates to change the condition of the actuator so the gate is biased toward the closed position, but is held open by engagement of the gate member with the stack extending through the opening. When stack 66 is removed, gate member 74 returns to the closed position. Sensor 85 provides analog proportional signals associated with the positions of the gate member 74. The sensor 85 is in operative connection through an interface with one or more processors 23. In the exemplary embodiment, the signals produced by the sensor are analyzed through operation of the at least one processor, including comparing the signals and data stored in at least one data store corresponding to normal gate operation. In some exemplary embodiments, the stored data is previously stored through operation of the processor during normal dispensing and gate movement operations. If movement of the gate member 74, as represented by the generated signals as determined by the processor, falls within a programmed normal range, the controller causes the machine to continue normal operations.
In the exemplary embodiment, sensor 85 is operable to detect movement that corresponds to abnormal movement of gate member 74. For example, if no stack 66 is present, but the gate member 74 is displaced from the closed position, the sensor 85 generates at least one signal indicative of gate movement. Processor 23 is operative to analyze the generated signals relative to data corresponding to normal gate activity and thereby determine abnormal gate movement and a suspect condition. The at least one processor operates to generate at least one signal corresponding to determining the suspect condition. The machine 10 may then operate in accordance with its programming to take one or more protective actions.
In another example, when stack 66 is present and extends from the opening, under normal conditions, gate member 74 can be moved against the biasing force sufficiently to allow a user to remove stack 66 without damaging any bills. Biasing members 76, 78 urge gate member 74 toward a closed condition, applying pressure to hold the stack 66 extending from the opening. If gate member 74 is sensed as abnormally displaced away from stack 66 while the stack is present, or if gate member 74 remains open after stack 66 is removed, such abnormal gate movement is detected through signals from sensor 85. The processor analyzes the signals corresponding to movement of the gate to determine if the signals correspond to at least one suspect condition, and operates to cause the machine to take one action in response thereto.
As can be appreciated, the described approach has advantages compared to some ATM gate constructions, such as a machine that includes only a “gate closed” switch that indicates “not closed” as long as a stack remained untaken. In such constructions, during stack presentation operation, the gate member could be lifted fully open, away from the stack, or the gate held open for a time after stack removal, without the machine sensing any unusual activity regarding change in gate member condition. Thus it is more likely a trap or other device could be inserted into the opening, or the machine hardware otherwise compromised without detection of such actions.
In the exemplary embodiment, the analog sensor 85 which is operative to indicate the position of the gate relative to the closed position, in conjunction with processor 23 is operable to detect abnormalities in gate member movement, prompting the machine to take one or more protective actions. The protective actions may include running a screening test for problems or path obstructions, or other actions that can be taken by the machine responsive to operation of the processor upon determining that the gate movement corresponds to at least one abnormal or suspect condition.
In operation, when no transaction is occurring at the machine, the gate member 74 remains in a closed position and is locked from movement by the mechanism that can move the gate. During a transaction in which a stack of sheets are to be presented to a user, the gate member 74 moves away from a closed position in response to operation of the at least one processor 23. With the gate member in the open position, the machine 10 operates to cause a presenter to move the stack from a delivery position in which the stack is accumulated to extend the currency stack 66 outward through the user opening 68. As the stack is extended, the gate member 74 moves toward the closed position, but remains open in biased supporting connection with the stack 66.
The analog sensor 85 in operative connection with the gate member 74 is operable to generate at least one signal indicative of the extent that the gate member 74 is disposed away from the closed position. The generated signal is analyzed through operation of the processor and, responsive to stored data, determines if the signal corresponds to a suspect condition.
In the exemplary embodiment, the generated signals may indicate the possibility that a suspect condition exists. For example, in normal operation, the proportional signal generated by the sensor would indicate that the gate member is disposed a certain extent, say X, away from the closed position corresponding to the known quantity of currency sheets in stack 66. After the stack is sensed by other sensors such as the sensor schematically indicated S, is taken, the spring biased gate member 74 should spring shut, at which time the proportional signal would indicate that the gate member is in the closed position. A signal indicating a slight increase in X, for a limited period of time as the stack is pulled from the opening, would be considered within the normal movement of the gate member during the time that it is detected that the user is taking the stack.
However, if the proportional signal indicates an unexpected increase in the extent that the gate member 74 is disposed away from the closed position, such a situation would be identified by the processor as associated with a suspect condition. The gate member 74 may have been forced into a wider open condition for unlawful purposes. Since the gate member 74 is closed and locked during non-transaction periods, unscrupulous activity may occur during a transaction, when the gate member 74 is moved to an open condition. As noted above, in some gate assembly constructions, such activity would be undetectable by merely a “gate closed” switch. The system and methods of the exemplary embodiment address this problem.
In another exemplary embodiment, the sensor signals to the processor may be indicative of the amount of time that the gate member 74 is disposed away from the closed position. Thus, during normal operations, the signals produced responsive to the sensor would correspond to an amount of time normally associated with the gate member 74 being in an open condition, based on sensing removal of the stack. If during operation of the machine, a generated signal signifies that the time associated with the gate member being in an open condition is not consistent with the removal of the stack, a suspect condition is determined through operation of the processor.
In an exemplary embodiment, if the generated signals correspond to a suspect condition, the processor operates to cause the machine to operate to take at least one protective action. In one exemplary embodiment, the protective action can include a verification process. The verification process can be similar to that described in U.S. Pat. No. 6,315,194, previously incorporated herein. In the illustrative verification process, a single sheet, such as a test sheet may be first sent through the dispenser path to a delivery position adjacent the customer accessible opening. In executing the verification process, signals from at least sensor S located adjacent to the customer accessible outlet opening can be used to verify that the test sheet will reach the customer. The sensor S is operable to indicate to the controller whether the test sheet was in a position accessible to the customer. Of course this approach is exemplary.
A successful transport of the test sheet to determine the proper operability of the dispensing path may also be time dependent such that the test sheet must be sensed as reaching the destination within certain time parameters. The signals from the sensor sensing the test sheet are operative to indicate to the at least one processor that the sheet dispensing path has not been tampered with and that the machine may proceed to attempt to deliver additional sheets to the customer in the course of transactions that the customer may request.
Verification sensors such as sensor S may additionally be positioned at additional strategic locations, such as the entry and exit locations of the transport paths. It should be understood that sensors S along the sensing path may include sensors that directly sense sheets as well as sensors for gates, mechanisms or other devices which must operate to have a test sheet reach a customer.
In the execution responsive to the operation of the at least one processor of the exemplary verification process, if an unexpected condition is sensed, then the processor would indicate a fault and prevent further attempted dispensing operations of the machine and indicate that a malfunction has occurred.
The processor, upon the fault condition being determined, may automatically operate to cause the ATM to notify proper personnel of the fault condition. This could be done by the machine sending one or more messages to remote computers.
In an exemplary embodiment, the protective action can include operating an alarm mechanism to alert a person at a remote location that a suspect condition is indicated.
In an exemplary embodiment, the protective action can include operating a video image capture system. The image can be used to identify an unauthorized user who may be tampering with the machine.
In another exemplary embodiment, the protective action can include generating a service request. The service request can alert service personnel that the machine should be inspected for a possible security breach. Embodiments may include features described in U.S. Pat. No. 5,984,178, which is incorporated herein by reference.
In some exemplary embodiments, data corresponding to a plurality of normal signals produced by a sensing device responsive to normal movement of the gate member can be stored in a data store through operation of the processor. Normal movement of the gate member includes, for example, moving away from the closed position in response to an associated transaction step carried out by the machine responsive to operation of the processor. Normal movement of the gate member may also include the gate member being positioned away from the closed position an extent corresponding to the quantity of currency bills in the stack. The generated sensor signal is compared through operation of the processor to data corresponding to the plurality of normal signals to determine if a suspect condition is indicated.
In another exemplary embodiment, computer software instructions stored in the data store are executed by at least one processor to cause the ATM to carry out the methods disclosed herein.
In another exemplary embodiment, machine readable media includes the instructions that are executed by the at least one processor and operative to cause at least one processor in the ATM to carry out the methods disclosed herein. In exemplary embodiments, the media may include a hard drive, solid state memory, magnetic memory or other suitable media for storing such instructions.
In another exemplary embodiment, a method includes receiving a transaction request from a user through at least one input device of the ATM to carry out a transaction in which at least one sheet is dispensed to the user. The at least one sheet is moved from a storage area in the machine to a delivery position from which sheets are accumulated for delivery from the machine, responsive to operation of at least one processor in the machine. A gate member controlling access through an opening in a housing of the machine is moved responsive to operation of the at least one processor from a closed position to an open position. Thereafter, with the gate member in the open position, the machine is operated responsive to the at least one processor, to move the at least one sheet from the delivery position outward from the machine so as to extend through the opening, so that the user may take the at least one sheet. While in the open position, the gate member is biased against the at least one sheet extending in the opening as the gate is urged toward the closed position. At least one sensor, in operative connection with the gate member, generates at least one signal corresponding to the extent that the gate member is disposed from the closed position. The generated at least one signal is analyzed through operation of the at least one processor to determine if the at least one signal corresponds to a suspect condition. If the generated signal corresponds to a suspect condition, the at least one processor operates to cause the machine to operate to take at least one protective action.
In another exemplary embodiment, a method includes generating through at least one sensor in operative connection with a gate member, at least one signal corresponding to an extent of movement of the gate member, wherein the gate member controls access to an interior area of the machine through a currency delivery opening of an automated banking machine. The at least one signal is analyzed through operation of at least one processor to determine if the at least one signal corresponds to an unusual and/or suspect condition.
In another exemplary embodiment, a method includes generating through at least one sensor in operative connection with a gate member, a plurality of signals corresponding to normal movement of the gate member, wherein the gate controls access through a currency dispensing opening of an automated banking machine. Data corresponding to the plurality of generated signals are stored in at least one data store through operation of at least one processor of the automated banking machine. In a subsequent machine operation, at least one subsequent signal corresponding to a subsequent movement of the gate, is generated through operation of the at least one sensor in operative connection with the gate member. Thereafter, the at least one processor is utilized to analyze the subsequent signal relative to the stored data corresponding to the plurality of signals corresponding to normal operation, to determine if the at least one subsequent signal corresponds to an abnormal and/or suspect condition. If the at least one subsequent signal is determined by the at least one processor to correspond to a suspect condition, the at least one processor is operative to cause the machine to operate to take at least one protective action. The at least one protective action may include operating the at least one processor to cause the machine to conduct a verification process to test whether a sheet material dispensing path in the automated banking machine is unobstructed. Of course this approach is exemplary.
In one exemplary embodiment, the stored data corresponding to signals which correspond to normal movement of the gate member, are indicative of an extent that the gate member is disposed away from the closed position. This displacement may be based on the number of sheets in the presented stack as determined by the at least one processor. In another exemplary embodiment, the stored data corresponding to signals which correspond to normal movement of the gate member, are indicative of an amount of time that the gate is disposed from the closed position relative to stack movement. In other exemplary embodiments, the stored data may correspond to both displacement and time, and/or other sensed parameters such as, for example, acceleration, velocity, stress, power, voltage, amperage, force or other data usable to analyze gate operation.
For example, a suspect condition may be indicated if the at least one generated signal corresponds to a condition indicative of an increase in the extent that the gate member is disposed from the closed position after the gate member has moved toward the closed position to engage a stack. Because the gate member is biased toward the closed position, such an increase may indicate that the gate member is being forced toward the open position for insertion of a foreign object into the machine. Of course this approach is exemplary. If such a suspect condition arises, at least one processor causes the machine to take one or more protective actions, such as the types described. It should further be understood that while the exemplary embodiment has discussed that regard to currency dispensing gates, the principles may be applied to other types of ATM gates.
Thus the new and improved automated banking machines of the exemplary embodiments achieve at least one of the above stated objectives, eliminate difficulties encountered in the use of prior devices and systems, solve problems and attain the desirable results described herein.
