Description

Technical Field

[0001] The present invention relates to a medium handling device and a deterioration determination method.

Background Art

[0002] In various medium handling devices involving the conveyance of media, it is often the case that media are conveyed using rubber belts or the like. For example, in an automatic transaction device such as an ATM (Automatic Teller Machine), banknotes and coins are conveyed by rubber rollers, rubber belts, etc., and are sent to deposit and withdrawal openings, cassettes for storing cash, etc. Also, in an automatic transaction device, cards and the like are also conveyed by rubber rollers, rubber belts, etc.

[0003] The rubber of the operating parts used for the conveyance of such various media has a lifespan according to the usage state, and it is preferable to replace it at an appropriate time. In this regard, conventionally, it has been common to determine the replacement time of the rubber of the operating parts by any of the following two methods. One is a method of judging replacement by visual inspection, which determines the replacement time by visually checking the appearance of the rubber based on the experience of the operator performing maintenance work or the like. The other is a method of regular replacement in which the rubber is replaced at a predetermined fixed period.

[0004] Also, as a technology related to the deterioration of the rubber of the operating parts, a technology for detecting the deterioration of a rubber belt by irradiating infrared rays has been proposed. Also, a technology has been proposed in which an evaluation medium is fed out, conveyed at a predetermined timing, the passing time is detected, and the characteristic deterioration of a rubber roller, a conveyance belt, etc. is determined and notified based on the detected passing time. In addition, a technology has been proposed in which the trailing edge passage of the printed paper being conveyed is detected by a sensor, the passing time of the printed paper is obtained, the passing time is corrected, and a failure diagnosis is performed based on the degree of deviation from the normal range.

[0005] Note that in an automatic transaction device, in recent years, it has become possible to acquire various information inside the device, and efforts are being made to integrate that information to streamline operations.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in determining the replacement timing by visual inspection for replacement judgment, the operator has to frequently inspect the device in order to replace it at an appropriate time, which increases the workload of maintenance and the like. Also, it largely depends on the skills of the operator, resulting in variations in the replacement timing, and there is a risk that the replacement timing may be too early or too late, making it difficult to replace it at an appropriate time. In addition, since the degree of deterioration of the rubber of the operating parts varies depending on the operating environment such as temperature and humidity and the operating conditions such as the number of operations, it is difficult to replace it at an appropriate time if regular replacement is carried out uniformly. Thus, it is difficult to operate efficiently by either the method of replacement judgment by visual inspection or the method of regular replacement.

[0008] Furthermore, in the technique of irradiating infrared rays to determine the deterioration of rubber, it is difficult to incorporate it into the device from the viewpoints of space and cost, and it is difficult to operate efficiently. Also, in the technique of determining the characteristic deterioration of rubber rollers, conveyor belts, etc. based on the passing time of conventional evaluation media, the degree of deterioration has not been calculated, and it is difficult to appropriately specify the replacement timing because it is not known how much deterioration has occurred, making it difficult to operate efficiently. Also, in the technique of performing fault diagnosis based on the degree of deviation from the normal range of the passing time of the printed paper being conveyed, the degree of deterioration has not been calculated, and it is difficult to specify an appropriate replacement timing, making it difficult to operate efficiently.

[0009] The disclosed technology has been made in view of the above, and an object thereof is to provide a medium handling device and a deterioration determination method that improve operation efficiency.

Means for Solving the Problems

[0010] In one aspect of the medium handling device and the deterioration determination method disclosed in the present application, a rubber member moves a medium. A sensor detects the presence of the medium at a predetermined position with respect to the rubber member. A deterioration determination unit calculates a first passage time of the medium in a predetermined range on the movement path by the rubber member from the detection result of the medium by the sensor when the medium is moved using the rubber member, calculates a delay time from the reference passage time of the medium in the predetermined range in a state where the rubber member has no deterioration and the first passage time, and quantifies the degree of deterioration of the rubber member based on the delay time.

[0015] The memory 102 expands various programs read by the main control unit 101 from the hard disks 103 and 104. Also, the memory 102 temporarily stores data during the execution of processing by the main control unit 101.

[0016] The hard disks 103 and 104 are, for example, duplicated for system protection. The hard disks 103 and 104 store various programs including programs for realizing the functions of the main control unit 101 including a transaction processing unit 121 and a degradation determination unit 122.

[0017] The host communication control unit 105 has an interface for mediating communication between the main control unit 101 and a host computer. For example, the host communication control unit 105 transmits a payment transaction message created by the transaction processing unit 121 to the host computer via a network. Also, the host communication control unit 105 receives a response message transmitted from the host computer via the network and outputs it to the transaction processing unit 121.

[0018] The display device 107 is, for example, an LCD (Liquid Crystal Display). The input device 109 is, for example, a touch panel and is arranged integrally with the display device 107 which is an LCD.

[0019] The image display control unit 106 receives an instruction from the main control unit 101 and causes various images to be displayed on the display device 107.

Additionally, for example, upon receiving an instruction from the transaction processing unit 121, the image display control unit 106 causes various screens such as a host communication screen, a card return screen, and an end screen to be displayed on the display device 107.

[0020] The key input control unit 108 acquires information input by the user using the input device 109 and outputs it to the main control unit 101. For example, when a transaction key on the transaction selection screen is pressed, the key input control unit 108 acquires information on the transaction corresponding to the pressed transaction key and outputs it to the transaction processing unit 121. Also, the key input control unit 108 outputs information on the PIN input using the PIN input screen and the PIN re - input screen to the transaction processing unit 121. Further, the key input control unit 108 outputs information on the amount input using the amount input screen and the amount re - input screen to the transaction processing unit 121. Additionally, when a correction button or a confirmation button is pressed on each screen, the key input control unit 108 outputs a correction notification or a confirmation completion notification to the transaction processing unit 121 according to the pressed button.

[0021] The customer camera 110 receives control from the transaction processing unit 121 and captures an image in front of the automatic transaction device 10. Thereafter, the customer camera 110 outputs the captured image data to the transaction processing unit 121.

[0022] The IO control unit 111 receives instructions from the transaction processing unit 121 of the main control unit 101 and comprehensively controls the handling of bills, coins, passbooks, cards, and receipts in transactions. The IO control unit 111 receives a payment instruction from the transaction processing unit 121 and causes the bill processing unit 112 and the coin processing unit 113 to make bill and coin payments. Also, the IO control unit 111 receives a deposit processing instruction from the transaction processing unit 121 and controls the bill processing unit 112 and the coin processing unit 113 to be in a deposit state. Thereafter, the IO control unit 111 notifies the transaction processing unit 121 of the information on the bills and coins deposited in the bill processing unit 112 and the coin processing unit 113. Also, the IO control unit 111 receives a passbook receipt processing instruction from the transaction processing unit 121 and controls the passbook processing unit 114 to be in a passbook receipt state. Then, the IO control unit 111 notifies the transaction processing unit 121 of the passbook information acquired by the passbook processing unit 114. Thereafter, the IO control unit 111 receives a passbook processing instruction from the transaction processing unit 121 and causes the passbook processing unit 114 to perform posting and discharging processes. Also, the IO control unit 111 receives a card receipt processing instruction from the transaction processing unit 121 and controls the card / receipt processing unit 115 to be in a card receipt state. Then, the IO control unit 111 notifies the transaction processing unit 121 of the card information acquired by the card / receipt processing unit 115. Thereafter, the IO control unit 111 receives a card processing instruction from the transaction processing unit 121 and causes the card / receipt processing unit 115 to perform a card discharging process. Also, the IO control unit 111 receives a receipt issuance instruction from the transaction processing unit 121 and causes the card / receipt processing unit 115 to create and issue a receipt.

[0023] The bill processing unit 112 receives control from the IO control unit 111 and performs deposit and payment processes for bills using the bill input / output port. The coin processing unit 113 receives control from the IO control unit 111 and performs deposit and payment processes for coins using the coin input / output port.

[0024] The passbook processing unit 114 receives and returns a passbook using the passbook insertion / discharge port under the control of the IO control unit 111. Also, the passbook processing unit 114 posts to the passbook under the control of the IO control unit 111.

[0025] The card / receipt processing unit 115 receives and returns a card using the card insertion / discharge port under the control of the IO control unit 111. Also, the card / receipt processing unit 115 creates a receipt and issues it from the card insertion / discharge port under the control of the IO control unit 111.

[0026] The outlet 118 is connected to a commercial power supply. The power control unit 116 transforms the voltage of the electricity supplied from the commercial power supply via the outlet 118 and supplies it to each unit. Also, in the event of a power outage, the power control unit 116 transforms the voltage of the electricity supplied from the UPS 117 and supplies it to each unit. The UPS 117 stores the electricity supplied from the commercial power supply via the outlet 118. Then, in the event of a power outage, the UPS 117 supplies the stored electricity to the power control unit 116.

[0027] The main control unit 101 is realized by a CPU (Central Processing Unit) or the like. The main control unit 101 is connected to each unit via a bus and comprehensively controls each unit. The main control unit 101 has a transaction processing unit 121 that comprehensively manages the entire transaction processing including image acquisition, and a deterioration determination unit 122 that determines the degree of deterioration of the rubber.

[0028] The transaction processing unit 121 is realized by an application or middleware that causes the IO control unit 111 and the like to execute respective processes and operates the entire transaction processing.

[0029] The transaction processing unit 121 performs human detection using the video from the customer camera 110, and controls the transition between the energy-saving mode and the normal mode for each unit such as the host communication control unit 105, the image display control unit 106, the key input control unit 108, the IO control unit 111, and the power control unit 116.

[0030] In the normal mode, the transaction processing unit 121 instructs the image display control unit 106 to display the transaction selection screen on the display device 107. When the user starts a transaction, the transaction processing unit 121 executes transaction processing in cooperation with various units such as the host communication control unit 105, the image display control unit 106, the key input control unit 108, the IO control unit 111, and the power control unit 116.

[0031] For example, the transaction processing unit 121 instructs the image display control unit 106 to display various screens such as a card insertion guidance screen, a PIN input screen, a PIN re - input screen, an amount input screen, an amount re - input screen, an amount confirmation screen, a host communication screen, a card return screen, and an end screen. Also, the transaction processing unit 121 acquires input information from the user from the key input control unit 108. Then, the transaction processing unit 121 instructs various operations to the host communication control unit 105, the image display control unit 106, and the IO control unit 111 according to the input information. Also, the transaction processing unit 121 stores data in the memory 102, the hard disks 103 and 104 according to the input information.

[0032] The deterioration determination unit 122 performs deterioration determination of the rubber of the drive unit using the passing time of the test medium 220 in a predetermined range on the movement path. The details of the deterioration determination unit 122 will be described below.

[0033] FIG. 2 is a diagram for explaining the calculation of the passing time. The rubber roller 201, and the rubber belts 202 and 203 are moving parts that convey the test medium 220 using rubber. The test medium 220 is a test medium used for deterioration determination of rubber.

[0034] The rubber roller 201, and the rubber belts 202 and 203 are mounted on, for example, some or all of the banknote processing unit 112, the coin processing unit 113, the passbook processing unit 114, or the card / receipt processing unit 115 in FIG. 1. The rubber roller 201, and the rubber belts 202 and 203 are an example of a "rubber member".

[0035] For example, when mounted on the banknote processing unit 112, the rubber roller 201, as well as the rubber belts 202 and 203, convey banknotes to and from the deposit and withdrawal openings and to the cassette. Also, when mounted on the coin processing unit 113, the rubber roller 201, as well as the rubber belts 202 and 203, convey coins to and from the deposit and withdrawal openings and to the cassette. Further, when mounted on the passbook processing unit 114, the rubber roller 201, as well as the rubber belts 202 and 203, convey passbooks to the passbook reception opening and to the printing mechanism. Additionally, when mounted on the card / receipt processing unit 115, the rubber roller 201, as well as the rubber belts 202 and 203, convey cards to the card reception opening or the reading mechanism and convey receipts to the receipt reception opening.

[0036] The test medium 220 is a medium in a predetermined state without special features such as scratches or bends. By using the test medium 220 to determine the deterioration of the rubber, the influence of the state of the medium to be used can be suppressed, and a more accurate determination of deterioration can be made.

[0037] The test medium 220 is prepared according to what is conveyed by the operating parts to be subjected to deterioration determination. For example, when the operating parts mounted on the banknote processing unit 112 are the objects of deterioration determination, the test medium 220 is a test banknote. Also, when the operating parts mounted on the coin processing unit 113 are the objects of deterioration determination, the test medium 220 is a test coin. Further, when the operating parts mounted on the passbook processing unit 114 are the objects of deterioration determination, the test medium 220 is a test passbook. Additionally, when the operating parts mounted on the card / receipt processing unit 115 are the objects of deterioration determination, the test medium 220 is a test card and receipt.

[0038] The rubber roller 201 is a cylindrical operating member with a rubber layer provided around the roller core. The rubber roller 201 sandwiches the test medium 220 between itself and an object on which the test medium 220 is placed, and by rotating, it extrudes the test medium 220 in the D direction, which is the traveling direction.

[0039] The rubber belts 202 and 203 are operating members in which rubber belts are arranged in a ring shape. The rubber belts 202 and 203 move a medium placed on the rubber in the D direction, which is the direction of progress in the published gazette, by rotating in the direction along the annular circumference of the rubber. In this case, the D direction corresponds to the direction along the annular circumference of the rubber.

[0040] A sensor 211 is arranged between the rubber roller 201 and the rubber belt 202. The position of the sensor 211 is preferably near the point where the sent test medium 220 starts to be placed on the rubber belt 202 and within the range where the test medium 220 extruded by the rubber roller 201 moves. The sensor 211 detects the presence of the test medium 220 in a direction perpendicular to the D direction, which is the direction of progress of the test medium 220 with respect to the arranged position.

[0041] The sensor 211 is an example of a "first sensor". Also, the sensor 211 is an example of a "second sensor" arranged at the rear end in the direction of progress of the test medium 220 on the rubber belt 202. Here, the rear end in the direction of progress corresponds to the starting position of the conveyance of the test medium 220 by the rubber belt 202. Also, the position where the sensor 211 detects the presence of the test medium 220 is an example of a "predetermined position with respect to the rubber roller 201" and a "predetermined position with respect to the rubber belt 202".

[0042] Also, a sensor 212 is arranged between the rubber belt 202 and the rubber belt 203. The sensor 212 is preferably arranged near the point where the test medium 220 comes off the rubber belt 202 and near the point where the sent test medium 220 starts to be placed on the rubber belt 203. The sensor 212 detects the presence of the test medium 220 in a direction perpendicular to the D direction, which is the direction of progress of the test medium 220 with respect to the arranged position.

[0043] Sensor 212 corresponds to an example of a "third sensor" arranged at the front end in the traveling direction of the test medium 220 on the rubber belt 202. Here, the front end in the traveling direction corresponds to the end position where the conveyance of the test medium 220 by the rubber belt 202 ends. Also, sensor 212 corresponds to an example of a "second sensor" arranged at the rear end in the traveling direction of the test medium 220 on the rubber belt 203. Further, the position where sensor 212 detects the presence of the test medium 220 corresponds to an example of a "predetermined position with respect to the rubber belt 202" and a "predetermined position with respect to the rubber belt 203".

[0044] Also, sensor 213 is arranged at the end of the rubber belt 203 in the D direction. Sensor 213 is preferably arranged in the vicinity of the point where the test medium 220 comes off the rubber belt 203.

[0045] Sensor 213 corresponds to an example of a "third sensor" arranged at the front end in the traveling direction of the test medium 220 on the rubber belt 203. Also, sensor 213 detects the presence of the test medium 220 in a direction perpendicular to the D direction, which is the traveling direction of the test medium 220 with respect to the arrangement position. The position where sensor 213 detects the presence of the test medium 220 corresponds to an example of a "predetermined position with respect to the rubber belt 203".

[0046] Here, the rubber roller 201, and the rubber belts 202 and 203 are examples, and there are no particular restrictions on the number and shape, and other components may be used as long as they are moving parts that convey the medium by rubber. Also, sensors 211 to 213 are examples, and when there are other moving parts that convey the medium by rubber, other sensors are arranged at positions where they can detect the movement of the test medium 220 by those moving parts.

[0047] The deterioration determination unit 122 receives the detection results of the test medium 220 by sensors 211 to 213. Then, the deterioration determination unit 122 calculates the following respective passing times using the detection results by sensors 211 to 213.

[0048] The deterioration determination unit 122 calculates a measured value of the passing time from when the sensor 211 detects the leading end of the test medium 220 moving in the D direction until the sensor 211 detects the trailing end of the test medium 220 moving in the D direction in the automatic transaction device 10 during operation. The deterioration determination unit 122 sets this calculated time as the passing time of the test medium 220 in the rubber roller 201.

[0049] In this case, the moving range of the test medium 220 from when the sensor 211 detects the leading end of the test medium 220 moving in the D direction until the sensor 211 detects the trailing end of the test medium 220 moving in the D direction corresponds to a predetermined range of the moving path by the rubber roller 201. And the passing time from when the sensor 211 detects the leading end of the test medium 220 moving in the D direction until the sensor 211 detects the trailing end of the test medium 220 moving in the D direction is an example of the "first passing time".

[0050] Also, the deterioration determination unit 122 calculates a measured value of the passing time from when the sensor 211 detects the trailing end of the test medium 220 moving in the D direction until the sensor 212 detects the leading end of the test medium 220 moving in the D direction. The deterioration determination unit 122 sets this calculated time as the passing time of the test medium 220 in the rubber belt 202.

[0051] In this case, the moving range of the test medium 220 from when the sensor 211 detects the trailing end of the test medium 220 moving in the D direction until the sensor 212 detects the leading end of the test medium 220 moving in the D direction corresponds to a predetermined range of the moving path by the rubber belt 202. And the passing time from when the sensor 211 detects the trailing end of the test medium 220 moving in the D direction until the sensor 212 detects the leading end of the test medium 220 moving in the D direction is an example of the "first passing time".

[0052] Also, the deterioration determination unit 122 calculates a measured value of the time from when the sensor 212 detects the trailing end of the test medium 220 moving in the D direction until the sensor 213 detects the leading end of the test medium 220 moving in the D direction. The deterioration determination unit 122 sets this calculated time as the passing time of the test medium 220 in the rubber belt 203.

[0053] In this case, the movement range of the test medium 220 from when the sensor 212 detects the rear end of the test medium 220 moving in the D direction to when the sensor 213 detects the front end of the test medium 220 moving in the D direction corresponds to a predetermined range of the movement path by the rubber belt 203. And the time from when the sensor 212 detects the rear end of the test medium 220 moving in the D direction to when the sensor 213 detects the front end of the test medium 220 moving in the D direction corresponds to an example of the "first passing time".

[0054] In this embodiment, since the conveyance of the test medium 220 in a predetermined state is considered not to be affected by factors other than the deterioration of the rubber of the rubber roller 201 and the rubber belts 202 and 203, the deterioration determination unit 122 determines the measured value of the passing time in one measurement. However, in order to suppress measurement errors, the deterioration determination unit 122 may repeat the calculation of the passing time a predetermined number of times and use the average of the passing times for the predetermined number of times as the measured value of the passing time.

[0055] The deterioration determination unit 122 preliminarily holds the reference passing time of the test medium 220 in a state where there is no rubber deterioration for each of the rubber roller 201 and the rubber belts 202 and 203. For example, the deterioration determination unit 122 conveys the test medium 220 in the automatic transaction device 10 in an unused state and calculates the elapsed time of the movement of the test medium 220 for each of the rubber roller 201 and the rubber belts 202 and 203. The deterioration determination unit 122 repeats the calculation of the elapsed time of the movement of the test medium 220 in a state where the rubber is not deteriorated a predetermined number of times, for example, several thousand times. This predetermined number of repetitions corresponds to an example of the "first predetermined number of times". Then, the deterioration determination unit 122 calculates the average of the calculated elapsed times and stores it as the reference passing time. For example, the reference passing time calculated by conveying the test medium 220 before shipment may be stored in the deterioration determination unit 122.

[0056] The deterioration determination unit 122 subtracts the reference passing time of the rubber roller 201 from the measured value of the passing time of the test medium 220 in the rubber roller 201 during operation, and calculates the delay time of the passing of the test medium 220 in the rubber roller 201 during operation. Similarly, the deterioration determination unit 122 subtracts the reference passing time of the rubber belt 202 from the measured value of the passing time of the test medium 220 in the rubber belt 202 during operation, and calculates the delay time of the passing of the test medium 220 in the rubber belt 202 during operation. Further, the deterioration determination unit 122 subtracts the reference passing time of the rubber belt 203 from the measured value of the passing time of the test medium 220 in the rubber belt 203 during operation, and calculates the delay time of the passing of the test medium 220 in the rubber belt 203 during operation.

[0057] The deterioration determination unit 122 has a deterioration determination threshold for the passing time for detecting the deterioration of the rubber for each of the rubber roller 201 and the rubber belts 202 and 203. For example, if it is specified by the standard that the rubber belt 202 is deteriorated when the delay time is less than or equal to a predetermined time, the deterioration determination unit 122 holds that predetermined time as the deterioration determination threshold. Further, the deterioration determination unit 122 may hold the delay time immediately before being determined to be deteriorated as the deterioration determination threshold from past statistical information. The deterioration in this case means a state that is not suitable for use.

[0058] The deterioration determination unit 122 compares the calculated delay time with the deterioration determination threshold for each of the rubber roller 201 and the rubber belts 202 and 203. If there is one in which the delay time exceeds the deterioration determination threshold, the deterioration determination unit 122 detects the deterioration of the rubber of that one. Further, when the delay time does not exceed the deterioration determination threshold, the deterioration determination unit 122 calculates the percentage of the calculated delay time with the passing time of the deterioration determination threshold being 100%, and uses it as the deterioration rate of the rubber of the operating component.

[0059] Furthermore, the deterioration determination unit 122 has a predetermined deterioration rate as a threshold for replacement recommendation. For example, the deterioration determination unit 122 has a deterioration rate of 80% as the threshold for replacement recommendation. Then, the deterioration determination unit 122 compares the calculated deterioration rate with the threshold for replacement recommendation, and if the calculated deterioration rate exceeds the threshold for replacement recommendation, it determines that the rubber is a target for replacement recommendation. The target for replacement recommendation in this case means a state where it can be used but it is better to replace it.

[0060] After that, when the deterioration determination unit 122 determines that the rubber is deteriorated, it transmits the information on the occurrence of deterioration together with the information on the operating parts using the rubber to the host computer via the host communication control unit 105 or causes it to be displayed on the display device 107 to notify the user. Further, the deterioration determination unit 122 may store the information on the occurrence of deterioration together with the information on the operating parts using the rubber in the hard disk 103 or 104. In this case, the user can confirm the occurrence of deterioration using the display device 107 and the input device 109.

[0061] Also, for operating parts for which the deterioration determination unit 122 does not determine that the rubber is deteriorated, it transmits the information on the deterioration rate together with the information on the operating parts to the host computer via the host communication control unit 105 or causes it to be displayed on the display device 107 to notify the user. Also, when the rubber is a target for replacement recommendation, the deterioration determination unit 122 transmits to the host computer via the host communication control unit 105 or causes it to be displayed on the display device 107 that it is a target for replacement recommendation to notify the user. Further, the deterioration determination unit 122 may store the information on the deterioration rate and the information on the target for replacement recommendation together with the information on the operating parts in the hard disk 103 or 104. In this case, the user can confirm whether the rubber of each operating part has a deterioration rate and is a target for replacement recommendation using the display device 107 and the input device 109.

[0062] In addition, the deterioration determination unit 122 may notify the user of a predetermined replacement recommendation value for the deterioration rate, and prompt the replacement of the rubber for the operating parts whose deterioration rate exceeds the replacement recommendation value. For example, when the replacement recommendation value of the deterioration rate is 80%, the deterioration determination unit 122 notifies the user of that information. In this case, the user considers replacing the rubber of the operating part when the calculated deterioration rate is 80% or more.

[0063] FIG. 3 is a flowchart of the rubber deterioration determination process by the automatic transaction device according to the first embodiment. Next, with reference to FIG. 3, the flow of the rubber deterioration determination process of the operating parts by the automatic transaction device 10 according to the present embodiment will be described. Here, the deterioration determination process of the rubber of the rubber roller 201 as an operating part will be described as an example.

[0064] The rubber roller 201 starts to convey the test medium 220 (step S1).

[0065] The deterioration determination unit 122 determines whether the test medium 220 has passed through a predetermined range (step S2). Specifically, after the leading end of the test medium 220 in the D direction is detected by the sensor 211, the deterioration determination unit 122 confirms that the trailing end of the test medium 220 in the D direction has been detected by the sensor 211, and detects the passage of the predetermined range on the movement path of the test medium 220. In this case, the predetermined range is the movement range of the test medium 220 from when the leading end of the test medium 220 in the D direction is detected by the sensor 211 until the trailing end of the test medium 220 in the D direction is detected by the sensor 211.

[0066] If the test medium 220 has not passed through the predetermined range (step S2: NO), the deterioration determination unit 122 waits until the test medium 220 passes through the predetermined range.

[0067] On the other hand, if the test medium 220 has passed through the predetermined range (step S2: YES), the deterioration determination unit 122 calculates a measured value of the passing time of the predetermined range (step S3).

[0068] Next, the deterioration determination unit 122 subtracts a predetermined reference passing time from the measured passing time to calculate the delay time of the conveyance of the test medium 220 by the rubber roller 201 (step S4).

[0069] Next, the deterioration determination unit 122 determines whether the delay time is less than a predetermined deterioration determination threshold (step S5).

[0070] When the delay time is less than the deterioration determination threshold (step S5: affirmative), the deterioration determination unit 122 calculates the deterioration rate of the rubber of the rubber roller 201 by calculating the ratio of the delay time with the deterioration determination threshold set to 100% (step S6).

[0071] Thereafter, the deterioration determination unit 122 notifies the user of the deterioration rate of the rubber of the rubber roller 201 by transmitting the calculated deterioration rate of the rubber of the rubber roller 201 to the host computer via the host communication control unit 105 or the like (step S7).

[0072] On the other hand, when the delay time is equal to or greater than the deterioration determination threshold (step S5: negative), the deterioration determination unit 122 transmits a notification of the deterioration of the rubber of the rubber roller 201 to the host computer via the host communication control unit 105 or the like. Thereby, the deterioration determination unit 122 notifies the user of the deterioration of the rubber of the rubber roller 201 (step S8).

[0073] As described above, the automatic transaction device according to the present embodiment measures the passing time within a predetermined range on the movement path of the test medium, compares the delay time, which is the difference between the measured passing time and the reference passing time, with the deterioration determination threshold of the passing time, detects the occurrence of deterioration and calculates the deterioration rate, and notifies the result.

[0074] In this way, by determining deterioration based on the time taken for rubber to convey operating parts, deterioration can be determined without relying on the experience of the operator. Also, unlike regular replacement, rubber can be replaced at an appropriate time. Further, by providing the degree of rubber deterioration based on the deterioration rate, the user can appropriately grasp the deterioration state of the rubber and replace the rubber at an appropriate time. Moreover, by using a test medium, errors dependent on the medium in the test can be eliminated, and it becomes possible to accurately detect the occurrence of deterioration and calculate the deterioration rate. Therefore, continuous operation of the automatic transaction device can be maintained, reliability can be improved, costs for maintenance can be reduced, and overall, the operation of the automatic transaction device can be made more efficient.

Example

[0075] Next, Example 2 will be described. The automatic transaction device 10 according to this example is also represented by the block diagram of FIG. 1. Also, the automatic transaction device 10 according to this example also has the mechanism shown in FIG. 2. The automatic transaction device 10 according to this example determines the deterioration of the rubber of the operating parts using the passing time of the medium used in an actual transaction. Hereinafter, the automatic transaction device 10 according to this example will be described. In the following description, the operations of the respective parts similar to those in Example 1 will be omitted.

[0076] When the deterioration determination unit 122 receives an instruction for deterioration determination from the input device 109, for example, in the automatic transaction device 10, the following processing is executed during an actual transaction. Hereinafter, the operation of the deterioration determination unit 122 will be described with reference to FIG. 2. However, since the test medium 220 is not used in this example, various media such as banknotes and cards used in transactions are simply referred to as "media" here instead of the test medium 220.

[0077] When a transaction is carried out, the deterioration determination unit 122 calculates the passing time for one pass from when the sensor 211 detects the front end of the medium moving in the D direction until it detects the rear end of the medium moving in the D direction. The deterioration determination unit 122 executes the calculation of this passing time for one pass in a predetermined number of transactions, such as several thousand times. Then, the deterioration determination unit 122 calculates the average of the passing times for one pass for the predetermined number of times calculated, and uses it as the measured value of the passing time of the medium in the rubber roller 201 during operation.

[0078] Also, the deterioration determination unit 122 calculates the time for one pass from when the sensor 211 detects the rear end of the medium moving in the D direction until the sensor 212 detects the front end of the medium moving in the D direction. The deterioration determination unit 122 executes the calculation of this passing time for one pass in a predetermined number of transactions. Then, the deterioration determination unit 122 calculates the average of the passing times for one pass for the predetermined number of times calculated, and uses it as the measured value of the passing time of the medium in the rubber belt 202 during operation.

[0079] Also, the deterioration determination unit 122 calculates the time from when the sensor 212 detects the rear end of the medium moving in the D direction until the sensor 213 detects the front end of the medium moving in the D direction. The deterioration determination unit 122 executes the calculation of this passing time for one pass in a predetermined number of transactions. Then, the deterioration determination unit 122 calculates the average of the passing times for one pass for the predetermined number of times calculated, and uses it as the measured value of the passing time of the medium in the rubber belt 203 during operation.

[0080] After that, the deterioration determination unit 122 calculates the delay time using the measured values of the passing times of the rubber roller 201 and the rubber belts 202 and 203, compares the calculated delay time with the deterioration determination threshold value, and detects the occurrence of deterioration and calculates the deterioration rate of each rubber.

[0081] FIG. 4 is a flowchart of the rubber deterioration determination process by the automatic transaction device according to the second embodiment. Next, with reference to FIG. 4, the flow of the rubber deterioration determination process of the operating parts by the automatic transaction device 10 according to the present embodiment will be described. Here, the deterioration determination process of the rubber of the rubber roller 201 as an operating part will be described as an example. In this case, the automatic transaction device 10 is in operation and performing actual transactions.

[0082] The deterioration determination unit 122 determines whether the medium has passed through a predetermined range (step S11). Specifically, after the tip of the medium in the D direction is detected by the sensor 211, the deterioration determination unit 122 confirms that the rear end of the medium in the D direction has been detected by the sensor 211, and detects the passage of the predetermined range of the medium.

[0083] When the medium has not passed through the predetermined range (step S11: NO), the deterioration determination unit 122 waits until the medium passes through the predetermined range.

[0084] On the other hand, when the medium has passed through the predetermined range (step S11: YES), the deterioration determination unit 122 calculates the passing time for one time of the predetermined range (step S12).

[0085] Next, the deterioration determination unit 122 determines whether the calculation of the passing time for one time of the predetermined range of the medium has been repeated a predetermined number of times (step S13). When the calculation of the passing time for one time has not been performed a predetermined number of times (step S13: NO), the deterioration determination unit 122 returns to step S11.

[0086] On the other hand, when the repetition of the calculation of the passing time for one time a predetermined number of times is completed (step S13: YES), the deterioration determination unit 122 calculates the average of the passing times for one time for the predetermined number of times as the measured value of the passing time (step S14).

[0087] Next, the deterioration determination unit 122 subtracts a predetermined reference passing time from the measured value of the passing time to calculate the delay time of the conveyance of the test medium 220 by the rubber roller 201 (step S15).

[0088] Next, the deterioration determination unit 122 determines whether the delay time is less than a deterioration determination threshold value determined in advance (step S16).

[0089] When the delay time is less than the deterioration determination threshold value (step S16: affirmative), the deterioration determination unit 122 calculates the deterioration rate of the rubber of the rubber roller 201 by calculating the ratio of the delay time with the deterioration determination threshold value set to 100% (step S17).

[0090] Thereafter, the deterioration determination unit 122 notifies the user of the deterioration rate of the rubber of the rubber roller 201 by transmitting the calculated deterioration rate of the rubber of the rubber roller 201 to the host computer via the host communication control unit 105 (step S18).

[0091] On the other hand, when the delay time is greater than or equal to the deterioration determination threshold value (step S16: negative), the deterioration determination unit 122 transmits a notification of the deterioration of the rubber of the rubber roller 201 to the host computer via the host communication control unit 105. Thereby, the deterioration determination unit 122 notifies the user of the deterioration of the rubber of the rubber roller 201 (step S19).

[0092] As described above, the automatic transaction apparatus according to the present embodiment measures the passage time within a predetermined range using a medium used in transactions during operation, detects the occurrence of deterioration and calculates the deterioration rate, and notifies the result.

[0093] In this way, even when using media such as actual banknotes and cards used in transactions, it is possible to detect the deterioration of the rubber of the operating parts. Also in this case, it is possible to replace the rubber at an appropriate time without depending on the experience of the operator and different from regular replacement. Further, by using the average of the currency times for a predetermined number of times, it is possible to reduce the error depending on each medium used in the transaction, and it becomes possible to accurately detect the occurrence of deterioration and calculate the deterioration rate. Therefore, it is possible to maintain the continuous operation of the automatic transaction apparatus, improve the reliability, reduce the cost due to maintenance, and overall improve the efficiency of the operation of the automatic transaction apparatus.
