Paper sheet processing apparatus, paper sheet processing method, and paper sheet processing program

[0007] , ,

[0006] ,

[0001] The present invention relates to a paper sheet processing apparatus, a paper sheet processing method, and a paper sheet processing program.

[0002] As a paper sheet processing apparatus, for example, a banknote processing apparatus such as an Automated Teller Machine is known.

[0003] Conventionally, a paper sheet processing apparatus takes in paper sheets such as banknotes from a deposit and withdrawal section, identifies them in a discrimination section, stores them in a temporary storage, and then stores them in different cassettes according to the type of banknote. Among such paper sheet processing apparatuses, there is one configured with a roll-type storage as a temporary storage, in which banknotes are stored by being wound one by one onto a roll.

[0004] Japanese Patent Application Laid-Open No. 2012-98763, Japanese Patent Application Laid-Open No. 2023-5061, Japanese Patent Application Laid-Open No. 2020-35403, Japanese Patent Application Laid-Open No.

[0005] However, in a conventional paper sheet processing apparatus, when transporting a plurality of banknotes from a roll-type storage as a temporary storage to each cassette, if the banknotes overlap, misrouting may occur where they are transported to a cassette different from the designated destination.

[0006] For example, in a conventional paper sheet processing apparatus, after identifying and storing the types of banknotes stored in a roll-type storage in the order of storage, the banknotes are fed out in the reverse order of the storage order in the roll-type storage and transported to the cassette. Here, when a conventional paper sheet processing apparatus feeds out banknotes, if the second banknote and the subsequent third banknote overlap and are fed out, the overlapping second and third banknotes are recognized as a single second banknote. Therefore, in a conventional paper sheet processing apparatus, the banknotes fed out thereafter are shifted from the storage state, and the destinations of the subsequent banknotes to the cassette are recognized as being shifted one by one, resulting in misrouting.

[0007] On one aspect, an object is to provide a paper sheet processing apparatus, a paper sheet processing method, and a paper sheet processing program capable of suppressing the occurrence of misrouting.

[0008] In the first proposal, the paper sheet processing device includes a roll-type storage unit that winds each input paper sheet onto a roll film for temporary storage, a plurality of storage mechanisms provided for each type of paper sheet for storing the corresponding paper sheet, and a control unit that transports each paper sheet stored in the roll-type storage unit to the appropriate storage mechanism among the plurality of storage mechanisms. The control unit acquires a first value of an encoder when each paper sheet is stored in the roll-type storage unit, and uses a second value of the encoder when each paper sheet is unwound from the roll-type storage unit, along with the first value, to detect any abnormalities in the transport of each paper sheet.

[0009] According to one embodiment, the occurrence of incorrect sorting can be suppressed.

[0011] Below, an embodiment 1 of the paper sheet processing apparatus, paper sheet processing method, and paper sheet processing program according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this embodiment 1. Furthermore, each embodiment can be appropriately combined within a non-consistent range.

[0012] (Explanation of the Paper Sheet Processing Device) First, we will explain the paper sheet processing device 1. In Example 1, we will use Japanese yen as an example, but other banknotes such as dollar bills, voting rights, and securities such as stock certificates can also be processed in the same manner.

[0013] Figure 1 is a diagram illustrating a paper sheet processing device 1 according to Embodiment 1. The paper sheet processing device 1 includes a shutter unit 10, a paper input / output unit 11, a transport mechanism 12, an identification unit 13, an encoder 14, a roll-type storage unit 15, cassettes 16a, 16b, 16c, 16d, 16e, 16f, an exception handling mechanism 17, a dispensing sensor 18a, a transport path sensor 18b, and a control unit 20. Note that the parts shown here are merely examples, and other functional parts such as a touch panel or other control mechanisms may also be included.

[0014] The shutter unit 10 is a shutter attached to the deposit / withdrawal unit 11, which handles the deposit and withdrawal of banknotes in response to the user's banknote deposit and withdrawal transactions. The shutter unit 10 opens and closes.

[0015] The deposit / withdrawal unit 11 is an input / output unit that processes the deposit and withdrawal of banknotes in response to the user's banknote deposit and withdrawal transaction operations. The transport mechanism 12 is a drive unit that drives rollers, motors, etc. (not shown) to transport banknotes within the paper sheet processing device 1 via a transport path. For example, the transport mechanism 12 transports banknotes deposited into the deposit / withdrawal unit 11 to a roll-type storage unit 15, and then transports the banknotes from the roll-type storage unit 15 to each cassette.

[0016] The identification unit 13 is a processing unit or mechanism that performs various types of identification, such as determining the type of banknote, whether it is genuine or counterfeit, and the degree of damage to the banknote. For example, the identification unit 13 is installed on the transport path between the deposit / withdrawal unit 11 and the roll-type storage unit 15, and between the deposit / withdrawal unit 11 and the exception handling mechanism 17, and performs identification on each deposited banknote. The identification unit 13 can also perform identification on each banknote transported from the roll-type storage unit 15 to each cassette.

[0017] The encoder 14 is a device that outputs a signal corresponding to the rotation of a rotation detection roller (not shown). For example, the encoder 14 has a disc-shaped member that rotates together with the rotation detection roller. Slits are provided at predetermined angles on the outer circumference of the disc-shaped member. The encoder 14 detects changes in light intensity caused by the movement of the slits from the detection results of a detection unit (not shown). The control unit 20 calculates the rotation angle of the rotation detection roller according to the detected changes in light intensity. For example, the rotation detection roller is linked to the roll film 19 of a roll-type storage unit 15 and rotates in accordance with the winding and unwinding of the roll film.

[0018] The encoder 14 is not limited to the example described above and can take any form as long as it can count banknotes. The encoder 14 may be included in the roll-type storage unit 15, may be adjacent to the roll-type storage unit 15, or can be installed in any position as long as it can detect the behavior of the roll-type storage unit 15.

[0019] The roll-type storage unit 15 is a storage unit that winds each input (deposited) sheet of paper onto a roll film 19 and temporarily stores (holds) them. When storing, the roll-type storage unit 15 winds each banknote onto the roll film 19 one by one. When dispensing, the roll-type storage unit 15 rewinds the film and ejects each banknote one by one. The roll-type storage unit 15 is a temporary storage unit for temporarily storing banknotes. For example, the roll-type storage unit 15 stores each banknote that is normal from among the deposited banknotes in the order in which it is authenticated by the authentication unit 13. The roll-type storage unit 15 can store, for example, 300 sheets.

[0020] The paper sheet processing device 1 has multiple storage mechanisms for storing the corresponding paper sheets, each provided for each type of paper sheet. The paper sheet processing device 1 has multiple storage mechanisms, including cassettes 16a, 16b, 16c, 16d, 16e, and 16f.

[0021] For example, cassettes 16a and 16b are storage compartments for 10,000 yen bills (hereinafter sometimes simply referred to as "10,000 yen"). Cassettes 16c and 16d are storage compartments for 5,000 yen bills (hereinafter sometimes simply referred to as "5,000 yen"). Cassettes 16e and 16f are storage compartments for 1,000 yen bills (hereinafter sometimes simply referred to as "1,000 yen"). Note that cassette 16c may not be a storage compartment for 5,000 yen bills, but rather a storage compartment for rejected bills.

[0022] The exception handling mechanism 17 is a storage unit for storing (holding) banknotes that are not in normal condition (damaged or defective banknotes) among the banknotes that have been dispensed. For example, the exception handling mechanism 17 stores banknotes that have been identified as damaged or defective by the authentication unit 13 among the banknotes that have been dispensed. The exception handling mechanism 17 can store, for example, 600 banknotes.

[0023] The paper sheet processing device 1 is installed on a transport path that carries paper sheets and has multiple sensors that detect the paper sheets being transported. The multiple sensors include an unloading sensor 18a and a transport path sensor 18b. For example, each of the multiple sensors detects a banknote when it passes over the sensor.

[0024] The dispensing sensor 18a is installed on the transport path and outputs a detection signal to the control unit 20 when it detects the transport of banknotes. For example, the dispensing sensor 18a is installed near the connection between the roll-type storage unit 15 and the transport path. The dispensing sensor 18a also counts the number of banknotes dispensed. The dispensing sensor 18a determines the destination of the banknotes.

[0025] The transport path sensor 18b is installed on the transport path and outputs a detection signal to the control unit 20 when it detects the transport of banknotes. There may be multiple transport path sensors 18b in positions other than those shown in the figure. For example, each transport path sensor 18b is installed on the transport path where banknotes are transported, near the connection between the authentication unit 13, the roll-type storage unit 15, and each cassette and the transport path. The transport path sensor 18b counts the number of banknotes that pass through. In addition, each transport path sensor 18b can identify the transport status and passage status of the banknotes.

[0026] The control unit 20 is a processing unit that oversees the entire paper sheet processing device 1, and is an information processing device having a processor such as a CPU (Central Processing Unit). The control unit 20 transports each sheet of paper stored in the roll-type storage unit 15 to the appropriate storage mechanism from among a plurality of storage mechanisms. The control unit 20 also transports each banknote stored in the exception processing mechanism 17 based on the authentication result of the authentication unit 13. For example, the control unit 20 controls the starting and stopping of each motor that drives each cassette based on the transport order, and stores each banknote in the cassette according to its type based on the authentication result of the authentication unit 13. The control unit 20 is connected to each unit shown in Figure 1 in a communication manner.

[0027] The control unit 20 determines whether each banknote is being transported normally based on the detection results from the dispensing sensor 18a and the transport path sensor 18b. The control unit 20 determines the destination of the banknotes based on the detection results from the dispensing sensor 18a and the transport path sensor 18b. The control unit 20 can also identify the transport status of the banknotes and whether the banknotes have been transported to their destination based on the detection results from the dispensing sensor 18a and the transport path sensor 18b.

[0028] (Explanation of paper sheet storage process) Next, using Figures 2 and 3, we will explain the process from receiving paper sheets to storing them in the roll-type storage unit 15, and then storing them from the roll-type storage unit 15 into each cassette. Note that some parts of Figures 2 and 3, such as the shutter unit 10, have been omitted.

[0029] Figure 2 shows the flow of the banknote deposit and acceptance process according to Embodiment 1. As shown in Figure 2, the cash inserted into the deposit / withdrawal unit 11 is sent to the authentication unit 13 for authentication. If the authentication unit 13 determines that the cash is normal, the cash is stored in the corresponding roll-type storage unit 15.

[0030] Figure 3 shows the flow of the banknote deposit and storage process according to Embodiment 1. As shown in Figure 3, the cash accumulated in the roll-type storage unit 15 is stored in the corresponding cassettes based on the results of the identification by the identification unit 13 during the deposit acceptance process.

[0031] (Conveying Anomaly) Figure 4 shows an example of a conveying anomaly in a conventional paper sheet processing device. For example, a conveying anomaly occurs when banknotes overlap each other during transport. In the conventional device, when a conveying anomaly occurs, the banknotes may be missorted into a different cassette instead of the designated cassette. As shown in Figure 4, for example, the conventional device stores banknotes in the order of 1,000 yen bills 31a, 1,000 yen bills 31b, 5,000 yen bills 31c, and 1,000 yen bills 31d. The conventional device recognizes the first banknote stored in the roll-type storage compartment 15 as a 1,000 yen bill 31a, the second as a 1,000 yen bill 31b, the third as a 5,000 yen bill 31c, and the fourth as a 1,000 yen bill 31d.

[0032] Next, the conventional technology dispenses the 1,000 yen bills 31d, which were stored in the roll-type storage compartment 15, in the order of 5,000 yen bills 31c, 1,000 yen bills 31b, and 1,000 yen bills 31a. Here, if the 5,000 yen bill 31c overlaps with the 1,000 yen bill 31b, the conventional technology recognizes the 1,000 yen bill 31b and the 5,000 yen bill 31c as a single large second bill 41.

[0033] Furthermore, if transport continues in this manner, the last 1,000 yen bill 31d, which should be recognized as the fourth bill, will be mistakenly recognized as the third bill and sorted into the third destination. Since the third bill stored is a 5,000 yen bill, the 1,000 yen bill 31d will be sorted into the cassette where the 5,000 yen bills are stored, resulting in missorting. Therefore, if more bills follow the 1,000 yen bill 31d, the missorting will continue with each bill shifted by one.

[0034] (Functional Configuration) The control unit 20 acquires a first value from the encoder 14 when each sheet of paper is stored in the roll-type storage unit 15 (sometimes simply referred to as "storage time"), and uses the first value and a second value from the encoder 14 when each sheet of paper is unwound from the roll-type storage unit 15 (sometimes referred to as "unwound time") to detect any abnormalities in the transport of each sheet of paper.

[0035] For example, the control unit 20 calculates the rotation angle of the rotation detection roller for each banknote stored in the roll-type storage compartment 15 in the order of 1,000 yen bill (first bill when stored in the roll-type storage compartment 15), 1,000 yen bill (second bill when stored), 5,000 yen bill (third bill when stored), and 1,000 yen bill (fourth bill when stored), as the first value of the encoder 14.

[0036] Furthermore, the control unit 20 calculates the rotation angle of the rotation detection roller for each banknote that is dispensed in the reverse order of the order in which the stored banknotes were stored from the roll-type storage unit 15: 1,000 yen note (first note dispensed from the roll-type storage unit 15), 5,000 yen note (second note dispensed), 1,000 yen note (third note dispensed), and 1,000 yen note (fourth note dispensed). Note that the 1,000 yen note dispensed as the first note and the 1,000 yen note dispensed as the fourth note dispensed are the same banknote. Similarly, the 2nd, 3rd, and 4th notes dispensed are the same banknotes as the 3rd, 2nd, and 1st notes dispensed, respectively.

[0037] For example, the control unit 20 compares a first value and a second value for each banknote when it is inserted and when it is dispensed. If the value of the encoder 14 at the time of dispensing is greater, it detects a transport abnormality. In other words, the control unit 20 calculates the value at the time of dispensing from the value of the encoder 14 of the banknote when it is inserted, and if the value of the encoder 14 becomes negative, it detects a transport abnormality.

[0038] Specifically, the control unit 20 detects a transport abnormality by calculating (subtracting) the rotation angle of the rotation detection roller for the first banknote during dispensing (a second value) from the rotation angle of the rotation detection roller for the fourth banknote during storage (a first value). Here, if the value obtained by calculating the rotation angle of the second value from the rotation angle of the first value is 0, the control unit 20 does not detect it as a transport abnormality.

[0039] Next, the control unit 20 detects a transport abnormality by calculating, as a second value, the rotation angle of the rotation detection roller for the second banknote when it is dispensed, based on the rotation angle of the rotation detection roller for the third banknote when it is stored, which is the first value. Here, the control unit 20 detects a transport abnormality if the value obtained by calculating the rotation angle of the second value from the rotation angle of the first value is negative. In other words, the control unit 20 detects a transport abnormality if the rotation angle of the second value is larger than the rotation angle of the first value.

[0040] As mentioned above, the transport malfunction occurs when banknotes overlap each other during transport, but this overlap is not limited to just two banknotes; multiple banknotes may overlap.

[0041] As an example of detecting the overlap of banknotes, the control unit 20 detects the overlap of banknotes from the rotation angle of the encoder 14. For example, when the control unit 20 detects that there is one banknote when the rotation angle of the encoder 14 is 0.5 degrees, if the rotation angle of the encoder 14 is from 0.6 degrees to 0.9 degrees, it detects that two banknotes are overlapping. Also, when the rotation angle of the encoder 14 is from 1.0 degrees to 1.5 degrees, the control unit 20 detects that three banknotes are overlapping.

[0042] (Specific example of conveyance abnormality: same type) Next, a specific example of the conveyance process to the cassette when the control unit 20 detects a conveyance abnormality will be described. First, the case where the banknotes related to the conveyance abnormality are banknotes of the same type will be described.

[0043] For example, the control unit 20 refers to the discrimination results of the discrimination unit 13 for a plurality of sheets of paper for which a conveyance abnormality has been detected. When the plurality of sheets of paper are discriminated as the same type, the control unit 20 continues to convey the plurality of sheets of paper.

[0044] Specifically, the control unit 20 refers to the type of banknote in the order of storage in the roll-type storage 15 as the discrimination result of the discrimination unit 13. The control unit 20 conveys all of the plurality of banknotes for which a conveyance abnormality has been detected to the cassette to which any one of the plurality of banknotes for which a conveyance abnormality has been detected is conveyed. That is, in the case of banknotes of the same type, even if the conveyance is continued, they will be conveyed to the designated cassette.

[0045] FIG. 5 is a diagram showing an example of the payout process when the banknotes related to the conveyance abnormality are banknotes of the same type. In FIG. 5, the case where the 5000-yen note (the first one at the time of payout) 51a and the 5000-yen note (the second one at the time of payout) 51b are overlapping will be described as an example.

[0046] Note that FIG. 5, and FIGS. 6 and 7 described later, show the process in which banknotes are paid out from the roll film 19 of the roll-type storage 15 and conveyed. The control unit 20 pays out the banknotes wound around the roll film 19 of the roll-type storage 15.

[0047] As shown in FIG. 5, the control unit 20 feeds out the five - thousand - yen bills 51a and 51b in this order and conveys them to the cassette through the conveyance path of the conveyance mechanism 12. Here, when the light - blocking time of the sensor when the bill passes through the pay - out sensor 18a is longer than that for one bill, for example, the control unit 20 detects that the five - thousand - yen bill 51a and the five - thousand - yen bill 51b overlap each other. That is, the control unit 20 detects the five - thousand - yen bill 51a and the five - thousand - yen bill 51b as one bill (the first bill at the time of feeding out).

[0048] Subsequently, when the light - blocking time of the sensor when the bill passes through the conveyance - path sensor 18b on the subsequent conveyance path is longer than that for one bill, for example, the control unit 20 detects that the overlap between the five - thousand - yen bill 51a and the five - thousand - yen bill 51b is maintained. Here, since the five - thousand - yen bill 51a and the five - thousand - yen bill 51b detected as one bill are identified as the same five - thousand - yen bill by the discrimination unit 13, the control unit 20 continues the conveyance and conveys them to the designated cassette. ​​​​​​​Furthermore, the control unit 20 can perform the same processing when resolving a transport anomaly while the transport of banknotes related to the transport anomaly described later is of a different type, and also when banknotes follow the banknotes related to the transport anomaly.

[0052] (Specific example of a transport error: different type) Next, we will explain the case where the banknotes involved in the transport error are of a different type. First, we will explain using the example of a case where the transport error does not resolve even while the banknotes involved in the transport error are in transit.

[0053] For example, the control unit 20 refers to the identification results of the identification unit 13 for multiple sheets of paper in which a transport abnormality has been detected. If the multiple sheets of paper are identified as being of different types, the control unit 20 obtains the detection result of at least one of the multiple sensors for the multiple sheets of paper in which a transport abnormality has been detected. If it determines, based on the detection result, that the transport abnormality of each sheet of paper is continuing, the control unit 20 stops the transport of the multiple sheets of paper.

[0054] Specifically, the control unit 20 obtains from the detection results of multiple sensors whether the overlapping of banknotes where a transport abnormality was detected is continuing or has been resolved. Furthermore, if the control unit 20 obtains a detection result indicating that the transport abnormality is continuing from at least the dispensing sensor 18a or any of the multiple transport path sensors, it determines to stop the transport.

[0055] Figure 6 shows an example of the dispensing process when the banknotes involved in the transport abnormality are of different denominations. As shown in Figure 6, the control unit 20 dispenses the 1,000 yen bill 52 and the 5,000 yen bill 53 in that order and transports them to the cassette via the transport path. Here, the control unit 20 detects from the detection result of the dispensing sensor 18a that the 1,000 yen bill (first bill dispensed) 52 and the 5,000 yen bill (second bill dispensed) 53 are overlapping. In other words, the control unit 20 detects the 1,000 yen bill 52 and the 5,000 yen bill 53 as a single banknote (first bill dispensed).

[0056] Next, the control unit 20 detects from the detection results of the transport path sensor 18b on the subsequent transport path that the overlap between the 1,000 yen bill 52 and the 5,000 yen bill 53 is maintained. At this point, the control unit 20 determines that the 1,000 yen bill 52 and the 5,000 yen bill 53, which were detected as a single banknote, have been identified as different types of bills by the identification unit 13, and therefore stops transporting them because continuing transport would result in missorting.

[0057] Next, we will explain using an example where the banknotes involved in the transport error are of different denominations and the transport error is resolved during transport.

[0058] For example, the control unit 20 refers to the identification results of the identification unit 13 for multiple sheets of paper in which a transport abnormality has been detected. If the multiple sheets of paper are identified as being of different types, the control unit 20 obtains the detection result of at least one of the multiple sensors for the multiple sheets of paper in which a transport abnormality has been detected. If it determines that the transport abnormality for each sheet of paper has been resolved based on the detection result, it continues to transport the multiple sheets of paper.

[0059] Specifically, the control unit 20 determines to continue transporting the banknotes if it detects that the transport abnormality has been resolved at least at the dispensing sensor 18a or at the transport path sensor to which the banknotes will next arrive. The transport abnormality is often resolved between the dispensing sensor 18a and the transport path sensor to which the banknotes will next arrive that is the closest in distance to the dispensing sensor 18a, in a section where the transport speed is not constant.

[0060] Figure 7 shows an example of the dispensing process when the banknotes involved in the transport abnormality are of different denominations. As shown in Figure 7, the control unit 20 dispenses the 1,000 yen bill 54 and the 5,000 yen bill 55 in that order and transports them to the cassette via the transport path. Here, the control unit 20 detects from the detection result of the dispensing sensor 18a that the 1,000 yen bill (first bill dispensed) 54 and the 5,000 yen bill (second bill dispensed) 55 are overlapping. That is, the control unit 20 detects the 1,000 yen bill 54 and the 5,000 yen bill 55 as a single banknote (first bill dispensed).

[0061] Next, the control unit 20 detects the 1,000 yen bill 54 and the 5,000 yen bill 55 respectively when the light blocking time of the conveyor path sensor 18b passing a banknote is the length of one banknote. In other words, the control unit 20 detects from the detection result of the conveyor path sensor 18b that the overlap between the 1,000 yen bill 54 and the 5,000 yen bill 55 has disappeared and the conveying abnormality has been resolved. At this point, the control unit 20 continues to convey the 1,000 yen bill 54 and the 5,000 yen bill 55 because the conveying abnormality has been resolved.

[0062] (Processing Flow) Figure 8 is a flowchart showing the process of storing banknotes in a roll-type storage unit 15 according to Embodiment 1. As shown in Figure 8, the deposit / withdrawal unit 11 of the paper sheet processing device 1 determines whether it has received a deposit transaction operation from a user (step S11). If the control unit 20 has received a deposit transaction operation (step S11: Yes), it transports the banknotes from the deposit / withdrawal unit 11 to the roll-type storage unit 15 (step S12).

[0063] Furthermore, the identification unit 13 identifies banknotes during the process of transporting them from the deposit / withdrawal unit 11 to the roll-type storage unit 15 (step S13). Subsequently, the control unit 20 determines whether it has obtained the identification result from the identification unit 13 (step S14). If the control unit 20 has not obtained the identification result, it repeats the process in step S14 (step S14: No).

[0064] Next, if the control unit 20 has obtained the identification result (step S14: Yes), it determines whether it has obtained the count result for each banknote when the banknotes were inserted from the encoder 14 (step S15). If the control unit 20 has not obtained the count result, it repeats the process in step S15 (step S15: No). The count result for each banknote when the banknotes were inserted is the first numerical value in the example described above.

[0065] Then, if the control unit 20 obtains the counting result (step S15: Yes), it stores the banknotes in the roll-type storage unit 15 (step S16). After that, the control unit 20 continues the process of step S21.

[0066] Figure 9 is a flowchart showing the flow of dispensing banknotes from the roll-type storage unit 15 according to Embodiment 1. As shown in Figure 9, the control unit 20 starts the dispensing process (step S21). The dispensing process may be started by default settings or by any operation of the user.

[0067] The control unit 20 determines whether it has obtained the counting result for each banknote when it is dispensed from the encoder 14 (step S22). If the control unit 20 has not obtained the counting result, it repeats the process in step S22 (step S22: No). The counting result for each banknote when it is dispensed is the second numerical value in the example described above.

[0068] Next, if the control unit 20 obtains the counting result (step S22: Yes), it determines whether the count of banknotes dispensed at the time of dispensing is less than the count of banknotes deposited at the time of deposit (step S23).

[0069] The control unit 20 detects a transport abnormality (step S26) if the encoder value of the banknotes at the time of dispensing is smaller than the count of the banknotes at the time of deposit (step S23: Yes). On the other hand, if the count at the time of dispensing is not smaller than the count of the banknotes at the time of deposit (step S23: No), the transport of banknotes continues (step S24).

[0070] If the control unit 20 detects a transport anomaly (step S26), it determines whether the subsequent banknotes of the multiple banknotes involved in the transport anomaly are headed to the same destination (step S27). If the control unit 20 determines that the multiple banknotes involved in the transport anomaly and the subsequent banknotes are headed to the same destination (step S27: Yes), it continues transporting the banknotes (step S24).

[0071] On the other hand, if the multiple banknotes involved in the transport anomaly and the subsequent banknotes are headed to different destinations (step S27: No), the control unit 20 determines whether the banknotes involved in the transport anomaly have been separated from the sensor installed on the transport path (step S28).

[0072] If the control unit 20 detects from the sensors installed on the transport path that a banknote related to a transport abnormality has been separated (step S28: Yes), it continues transporting (step S24). If the control unit 20 detects from the sensors installed on the transport path that a banknote related to a transport abnormality has not been separated (step S28: No), it stops transporting (step S29).

[0073] If the control unit 20 continues transporting banknotes (step S24), it transports the banknotes to the cassette and stores them in the cassette (step S25).

[0074] (Effects) The paper sheet processing device 1 according to Embodiment 1 includes a roll-type storage unit 15 that winds each input paper sheet onto a roll film 19 and stores it temporarily, a plurality of storage mechanisms provided for each type of paper sheet to store the corresponding paper sheet, and a control unit 20 that transports each paper sheet stored in the roll-type storage unit 15 to the appropriate storage mechanism among the plurality of storage mechanisms. The control unit 20 acquires a first value of the encoder 14 when each paper sheet is stored in the roll-type storage unit 15, and uses the second value of the encoder 14 when each paper sheet is unwound from the roll-type storage unit 15 and the first value to detect any abnormality in the transport of each paper sheet.

[0075] As a result, the paper sheet processing device 1 can detect overlapping banknotes by detecting changes in the values ​​of the encoder 14 when the banknotes are stored in and unloaded from the roll-type storage unit 15, thereby suppressing the occurrence of missorting.

[0076] Furthermore, the paper sheet processing device 1 according to Embodiment 1 further includes an identification unit 13 for identifying the type of paper sheets, and the control unit 20 refers to the identification results of the identification unit 13 for multiple paper sheets in which a transport abnormality has been detected, and if multiple paper sheets are identified as being of the same type, the transport of the multiple paper sheets is continued.

[0077] The paper sheet processing device 1 can flexibly change whether to continue or stop the transport of stacked banknotes to the cassette depending on the type of banknotes.

[0078] Furthermore, the paper sheet processing device 1 according to Embodiment 1 further includes an identification unit 13 for identifying the type of paper sheets, and a plurality of sensors installed on a transport path for transporting paper sheets to detect the transported paper sheets. The control unit 20 refers to the identification results of the identification unit 13 for the plurality of paper sheets in which a transport abnormality has been detected, and if the plurality of paper sheets are identified as being of different types, it obtains the detection result of at least one of the plurality of sensors for the plurality of paper sheets in which a transport abnormality has been detected. If it determines that the transport abnormality of each paper sheet is continuing based on the detection result, it stops the transport of the plurality of paper sheets.

[0079] This allows the paper sheet processing device 1 to prevent banknotes from being missorted by stopping the transport. Furthermore, if banknotes of different types are stacked together and the stacking is not resolved during transport, the paper sheet processing device 1 will stop transporting the banknotes, thus minimizing the interruption of transport.

[0080] Furthermore, the paper sheet processing device 1 according to Embodiment 1 further includes an identification unit 13 for identifying the type of paper sheets, and a plurality of sensors installed on a transport path for transporting paper sheets to detect the transported paper sheets. The control unit 20 refers to the identification results of the identification unit 13 for the plurality of paper sheets in which a transport abnormality has been detected, and if the plurality of paper sheets are identified as being of different types, it obtains the detection result of at least one of the plurality of sensors for the plurality of paper sheets in which a transport abnormality has been detected. If it determines that the transport abnormality of each paper sheet has been resolved based on the detection result, it continues transporting the plurality of paper sheets.

[0081] As a result, the paper sheet processing device 1 can continue transporting banknotes if the overlapping of banknotes is resolved while they are being transported from the roll-type storage unit 15 to the cassette.

[0082] Now, although we have described Embodiment 1 of the present invention, the present invention may be implemented in various other forms besides Embodiment 1 described above.

[0083] (Numerical values, thresholds, etc.) Furthermore, the various numerical values, thresholds, number of cassettes, banknote types, number of banknotes, etc. used in the above Example 1 are merely examples and can be changed at will. Also, the thresholds described in the example can be set arbitrarily, but it is preferable to set them to be longer than the time required for the cassette to start up and to operate at a speed sufficient to store banknotes, for example.

[0084] (System) The processing procedures, control procedures, specific names, and various data and parameters shown in the above documents and drawings may be changed at will unless otherwise specified. Furthermore, the specific examples, distributions, and numerical values ​​described in Example 1 are merely examples and may be changed at will.

[0085] Furthermore, the components of each illustrated device are functionally conceptual and do not necessarily need to be physically configured as shown. In other words, the specific forms of distribution and integration of each device are not limited to those shown. That is, all or part of them can be functionally or physically distributed and integrated in any unit depending on various loads and usage conditions. Moreover, each processing function performed by each device can be implemented, in whole or in any part, by a CPU and the program that is analyzed and executed by that CPU, or by hardware using wired logic.
