Description

[Technical Field]

[0001] The present invention relates to a technique for detecting the position of a paper sheet (for example, a banknote) when an error occurs in a paper sheet processing device that takes in, stores, pays out, etc., multiple types of paper sheets (for example, banknotes). [Background technology]

[0002] In recent years, devices made up of multiple units are often used in banknote handling devices (an example of a paper processing device) that take in, store, and refund multiple types of banknotes (an example of paper sheets) (see, for example, Patent Document 1). In such banknote handling devices, the path along which banknotes are transported tends to be long, so if the position of the banknote (transported object) can be detected with high accuracy when an error occurs, measures can be taken to quickly resolve the error.

[0003] [Patent Document 1] Patent No. 6389969 Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, in a banknote handling device composed of multiple units, there is a demand for technology that can detect the position of a banknote (transported object) with high accuracy when an error occurs. Furthermore, for example, if the management authority of each unit that makes up the banknote handling device is limited to different entities, when an error occurs, it is possible to determine which entity with management authority should take action by identifying the location of the remaining banknote and specifying the unit that should take measures to resolve the error (the unit where the remaining banknote is located). Therefore, there is a demand for technology that can identify the unit that should take measures to resolve the error (the unit where the remaining banknote is located) and specify the entity with management authority that should take action.

[0005] In view of the above problems, the present invention aims to realize a paper processing device, paper processing method, and program that can detect the position of paper (e.g., banknotes) with high accuracy when an error occurs in a paper processing device (e.g., banknote handling device, paper processing device) composed of multiple units. The present invention also aims to realize a paper processing device, paper processing method, and program that can determine which management authority entity should respond by locating the position of remaining paper (e.g., remaining banknotes) when an error occurs, and identifying the unit that is to take measures to resolve the error, even if the management authority of each unit that constitutes the paper processing device (e.g., banknote handling device, paper processing device) is limited to different entities. [Means for solving the problem]

[0006] In order to solve the above problem, a representative example (one aspect) of the invention disclosed in this application is a paper processing device comprising a paper input / output processing unit, a storage processing unit, a conveying path connection unit, a first conveying path sensor group, a second conveying path sensor group, a memory unit, and a control unit.

[0007] The paper input / output processing unit has an input / output port for inputting and outputting paper sheets, a return port for returning paper sheets, and a transport path for transporting paper sheets, and performs paper sheet recognition processing, partial paper sheet reservation processing, and paper sheet input / output processing.

[0008] The storage processing unit is provided with a transport path for transporting paper sheets, and performs processing to store paper sheets input by the paper sheet input / output processing unit.

[0009] The transport path connection unit has a transport path for transporting paper sheets from the paper sheet input / output processing unit to the storage processing unit, and for transporting paper sheets from the storage processing unit to the paper sheet input / output processing unit, and connects the paper sheet input / output processing unit and the storage processing unit.

[0010] The first transport path sensor group is one or more transport path sensors that are installed on the transport path of the paper input / output processing unit and that detect the passing status of paper sheets.

[0011] The second transport path sensor group is one or more transport path sensors that are installed on the transport path of the storage processing unit and that detect the passing status of paper sheets.

[0012] The memory unit stores data indicating the passing status of paper sheets for each conveying path sensor of the first conveying path sensor group as first log data, and stores data indicating the passing status of paper sheets for each conveying path sensor of the second conveying path sensor group as second log data.

[0013] The control unit performs processing to identify the positions of remaining pieces of paper (for example, banknotes) by analyzing the first log data and the second log data stored in the storage unit. [Effects of the Invention]

[0014] According to the present invention, it is possible to realize a paper processing device, paper processing method, and program that can detect the position of paper (e.g., banknotes) with high accuracy when an error occurs in a paper processing device (e.g., banknote handling device, paper processing device) composed of multiple units. Also, according to the present invention, even if the management authority of each unit that makes up the paper processing device (e.g., banknote handling device, banknote processing device) is limited to different entities, it is possible to realize a paper processing device, paper processing method, and program that can determine which management authority entity should respond when an error occurs by identifying the position of a remaining paper (e.g., a remaining banknote) and identifying the unit that is to take measures to resolve the error.

[0051] <1.2: Operation of the banknote handling device> The operation of the banknote handling machine 100 configured as above will be described with reference to the drawings.

[0052] FIG. 5 is a diagram for explaining the operation of the banknote handling machine 100 during a deposit process.

[0053] FIG. 6 is a diagram for explaining the operation of the banknote handling machine 100 during the confirmation process.

[0054] FIG. 7 is a diagram for explaining the operation of the banknote handling machine 100 during a dispensing process.

[0055] FIG. 8 is a diagram for explaining the operation of the banknote handling machine 100 during the collection process.

[0056] FIG. 9 is a diagram for explaining the operation of the banknote handling machine 100 during the collection process.

[0057] First, the following describes (1) the operation of the deposit process, (2) the operation of the settlement process, (3) the operation of the withdrawal process, and (4) the operation of the collection process of the banknote handling machine 100.

[0058] (1.2.1: Deposit processing) The deposit processing operation of the banknote handling machine 100 will be described (see FIG. 5).

[0059] In the banknote handling device 100, when a deposit process is performed, when one or more banknotes are inserted through the deposit port 11a, the control unit Psr1 receives a signal from the sensor that detects the banknotes and activates the transport mechanism to transfer the lump-sum deposit unit 12 and the deposited banknote transport path (transport path W t1 , W t2 , W t3 , W t4 , W t7 , W t8 , W t9 , W t10 , W t11 , W t12 , W t13 , W t14 , W t16 , W t17 ) (the transport path indicated by the thick line in FIG. 5) to take in (or return) the banknotes. The lump-sum deposit unit 12 removes the banknotes one by one from the top of the stack of banknotes set in the deposit / withdrawal port 11a and transports them to the centering unit 13. The banknotes transported to the centering unit 13 are subjected to a centering process by the centering unit 13, and then transported to the recognition unit 14.

[0060] The recognition unit 14 performs a recognition process on the banknotes moved to the recognition unit 14. Banknotes that are determined to be acceptable as a result of the recognition process are transported to the escrow unit 15, where they are wrapped one by one around the outer periphery of the drum of the escrow unit 15 and temporarily stored, waiting for confirmation of their deposit. On the other hand, banknotes that are determined to be unacceptable as a result of the recognition process (rejected banknotes) are transported to the return port 11b and discharged from the return port 11b to the outside of the machine.

[0061] In the banknote processing device 100, when multiple banknotes inserted at once are rejected, they are first accumulated in the dispensing and accumulating unit 16 (accumulating one or more banknotes) and then discharged collectively outside the machine through the return port 11b for return. Furthermore, when a customer requests the return of the banknotes by operating a cancel button (not shown), the banknotes that were temporarily stored in the temporary storage unit 15 are sent one by one to the dispensing and accumulating unit 16, and are stacked one by one by being wrapped around the outer periphery of the drum (a rotating dispensing drum) of the dispensing and accumulating unit 16. Then, when all the banknotes inserted by the customer have been accumulated on the outer periphery of the drum of the dispensing and accumulating unit 16, the drum of the dispensing and accumulating unit 16 rotates in the dispensing direction, causing the banknote bundle to protrude outward through the return port 11b and be returned, prompting the customer to collect it.

[0062] If the bill bundle that has been ejected from the return port 11b to the outside of the machine for return is not collected by the customer within a predetermined time, the drum of the payout / accumulation unit 16 is reversed in the return direction to return the bill bundle to the inside of the machine (the bill bundle is returned along the transport path W t16 , W t17 ) and stored in the banknote storing section 17 as a forgotten banknote.

[0063] (1.2.2: Confirmation process) Next, the operation of the confirmation process of the banknote handling machine 100 will be described (see FIG. 6).

[0064] In the banknote handling machine 100, when the confirmation process is performed, at the stage when the deposit of the banknotes escrowed in the escrow unit 15 is confirmed, the banknotes are sent out one by one from the escrow unit 15. (1) When the banknotes sent out from the escrow unit 15 are banknotes to be used as change, the banknotes are sent out along the first stored banknote transport path (transport path W t14 , W t13 , W t12 , W t11 , W t6 , W t5 , W t7 , W t8 , W m1 , W bi2 , W bi3 , Wbi4 , W bi5 (i: natural number, 1≦i≦N)) and stored in the ith recycling storage unit 31-i (any of the recycling storage units) according to denomination, and (2) if the banknote sent from the temporary holding unit 15 is a banknote that will not be used as change, the banknote is sent via the second stored banknote transport path (transport path W t14 , W t13 , W t12 , W t11 , W t6 , W t5 , W t7 , W t8 , W m1 , W b11 , W b21 , W b31 , W b41 , W b51 ), the banknotes are transported to the storage unit 32 and stored in the storage unit 32.

[0065] (1.2.3: Withdrawal process) Next, the operation of the dispensing process of the banknote handling machine 100 will be described (see FIG. 7).

[0066] In the banknote handling device 100, when performing a dispensing process, when dispensing banknotes as change, the banknotes stored in the ith recycling storage unit 31-i are removed and subjected to a recognition process by the recognition unit 14. If the recognition process shows that the banknotes are returnable, the banknotes are temporarily stacked in the dispensing and stacking unit 22 (one to multiple banknotes are stacked) and then dispensed as a lump sum from the return opening 11b as change. On the other hand, if the recognition process by the recognition unit 14 shows that the banknotes are non-returnable, the banknotes are temporarily stored in the escrow unit 15 and then transferred to the storage unit 32 for storage.

[0067] (1.2.4: Recovery Processing) Next, the operation of the collection process of the banknote handling machine 100 will be described (see FIGS. 8 and 9).

[0068] In the banknote handling device 100, when performing collection processing, the banknote in the ith recycling storage unit 31-i is sent to the escrow unit 15 at the end of business hours or the like, and is temporarily stacked in the escrow unit 15 (see FIG. 8). After that, the banknote temporarily stacked in the escrow unit 15 is transferred to the collected banknote transport path (transport path W t14 , W t13 , W t12 , W t11 , W t6 , W t5 , W t7 , W t8 , W m1 , W b11 , W b21 , W b31 , W b41 , W b51 ) and is transported to the storage section 32 and stored in the storage section 32.

[0069] In this manner, the banknote handling apparatus 100 executes (1) deposit processing, (2) confirmation processing, (3) withdrawal processing, and (4) collection processing.

[0079] FIG. 18 is a diagram schematically showing log data for each transport path sensor when an abnormal state is detected in the banknote handling machine 100 (state 3).

[0080] Hereinafter, the operation of the abnormal state detection process and the remaining banknote position identification process of the banknote handling machine 100 will be described based on the flowchart of FIG. 10 and with reference to FIGS.

[0081] (Step S1): In step S1, a process for setting the number of logs to be acquired is executed. Specifically, the following process is executed.

[0082] The control unit Psr1 of the banknote handling apparatus 100 calculates the maximum possible number Nmax of remaining banknotes in the banknote handling apparatus 100 based on the total length of the transport path of the banknote handling apparatus 100, the minimum input cycle (period) of banknotes when inputting banknotes into the banknote handling apparatus 100, and the transport speed of the banknote handling apparatus 100, Nmax = Int(L path_all / (V conv ×T min )) Int(x): Gaussian symbol (a function that returns the smallest integer greater than x) L path_all : Total length of the conveyance path of the banknote handling machine 100 Vconv : conveyance speed of the banknote handling machine 100 T min : Minimum input cycle of banknotes when inputting banknotes into the banknote handling machine 100 (period (minimum time required to input one banknote)) Then, the control unit Psr1 sets the maximum possible number Nmax of the number of remaining banknotes acquired as described above as the number of logs (number of data held as logs) Num_DLog of data (data on the sensor status held by each transport path sensor). Here, for ease of explanation, it is assumed that the control unit Psr1 acquires Nmax=5 and sets Num_DLog=5.

[0083] In the above, the control unit Psr1 obtains the maximum possible number of remaining banknotes Nmax and sets the number of logs Num_DLog, but this is not limited to this. For example, if the maximum possible number of remaining banknotes Nmax is known in advance, the number of logs Num_DLog (=Nmax) may be stored in advance, for example, in the memory unit Mem1.

[0084] The control unit Psr1 stores data acquired from each conveyance path sensor of the conveyance path sensor group G_c_snsr in the memory unit Mem1 so that data equivalent to the number of logs Num_DLog determined above is stored and held in the memory unit Mem1 for each conveyance path sensor of the conveyance path sensor group G_c_snsr of the banknote processing device 100. The control unit Psr1 acquires data indicating that a banknote has passed from each conveyance path sensor of the conveyance path sensor group G_c_snsr of the banknote processing device 100, and stores and holds the data (data identifying the banknote and data indicating that the banknote has passed) equivalent to the number of logs Num_DLog in the memory unit Mem1 (data equivalent to the latest number of logs Num_DLog is stored and held in the memory unit Mem1 in a queue memory format (FIFO memory format (FIFO: First In First Out))).

[0085] In addition, each of the transport path sensors of the transport path sensor group G_c_snsr of the banknote processing device 100 (in this embodiment, 28 transport path sensors (St1 to St11 , Sb0, Sb 11 ~Sb 14 , Sb 21 ~Sb 24 , Sb 31 ~Sb 34 , Sb 41 ~Sb 44 )) can acquire the sensor status as shown in Figure 11. The control unit Psr1 acquires a value (data) indicating the sensor status from each transport path sensor. The value (data) D indicating the sensor status is defined as follows: D=0: Neutral state (not in banknote ON waiting state) D=1: Waiting for banknote ON (When the previous transport path sensor on the transport path becomes active (ON), the transport path sensor (own sensor) enters this state) D=2: Waiting for OFF (the state in which the transport path sensor (own sensor) that has become active (ON) is in the active state (ON) until it is determined that a banknote has passed) D=3: Hole processing state (state until the process to detect whether there is a hole (or transparent part) in the middle of the bill or whether the end of the bill has passed is completed) D=4: Passed (hole processing is completed and the bill is determined to have passed) The control unit Psr1 acquires data indicating that a banknote has passed (data indicating that the above D=4) from each transport path sensor of the transport path sensor group G_c_snsr of the banknote processing device 100, along with data identifying the passed banknote, and stores and holds the data (data identifying the banknote and data indicating that the banknote has passed) for the number of logs Num_DLog (corresponding to DLog(0) to DLog(4) in Figure 11) in the memory unit Mem1.

[0086] (Step S2): In step S2, an abnormal state detection process is executed. Specifically, the following process is executed.

[0087] The control unit Psr1 monitors whether the group of anomaly detection sensors G_anm_snsr of the banknote processing device 100 has detected that the state of the banknote processing device 100 is abnormal. The control unit Psr1 investigates the sensor values ​​(data) output from the group of anomaly detection sensors G_anm_snsr, and if there is an abnormality in the sensor values ​​(data), it determines that the state of the banknote processing device 100 is abnormal. If the control unit Psr1 determines that the state of the banknote processing device 100 is abnormal, it proceeds to step S3, and if it determines that the state of the banknote processing device 100 is not abnormal, it returns the process to step S2 (continuing the process of monitoring the state of the banknote processing device 100).

[0088] The processing of steps S3 to S5 will be described using (1) the case of state 1 shown in FIG. 12, (2) the case of state 2 shown in FIG. 15, and (3) the case of state 3 shown in FIG. 17 as specific examples.

[0089] In state 1 shown in Figure 12, during the confirmation process, five banknotes (hereinafter referred to as banknotes Bill(0), Bill(1), Bill(2), Bill(3), and Bill(4)) are normally stored in the storage unit 32, and then the banknote processing device 100 enters an abnormal state (for example, a state in which a banknote is jammed at a predetermined position and the banknote cannot be transported normally), and four banknotes (hereinafter referred to as banknotes Bill(5), Bill(6), Bill(7), and Bill(8)) remain in the banknote processing device 100.

[0090] In state 2 shown in Figure 15, during the confirmation process, five banknotes (hereinafter referred to as banknotes Bill(0), Bill(1), Bill(2), Bill(3), and Bill(4)) are normally stored in the storage unit 32, and then the banknote processing device 100 enters an abnormal state (for example, a state in which a banknote is jammed at a predetermined position and the banknote cannot be transported normally), and two banknotes (hereinafter referred to as banknotes Bill(5) and Bill(6)) remain in the banknote processing device 100.

[0091] In state 2 shown in Figure 17, during the confirmation process, five banknotes (hereinafter referred to as banknotes Bill(0), Bill(1), Bill(2), Bill(3), and Bill(4)) are normally stored in the storage unit 32, and then the banknote processing device 100 enters an abnormal state (for example, a state in which a banknote is jammed at a predetermined position and the banknote cannot be transported normally), and two banknotes (hereinafter referred to as banknotes Bill(5) and Bill(6)) remain in the banknote processing device 100.

[0092] <<In the case of status 1>> (Step S3): In step S3, an operation mode and transport path specification process is executed. Specifically, the following process is executed.

[0093] The control unit Psr1 acquires the current operation mode of the banknote handling machine 100. In the case of State 1 shown in Fig. 12, the banknote handling machine 100 is in a state where the settlement process is being performed, so the control unit Psr1 determines that the current operation mode of the banknote handling machine 100 is a mode where the settlement process is being performed (acquires the operation mode as the operation mode for the settlement process).

[0094] Then, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process. Specifically, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process as the transport route shown in the graph in FIG.

[0095] (Step S4): In step S4, a log acquisition process is executed. Specifically, the following process is executed.

[0096] The control unit Psr1 identifies the transport path sensors installed on the transport path based on the transport path identified in step S3 (operation mode: confirmation process), and sets the identified transport path sensors as the transport path sensors for which logs are to be acquired. In the case of state 1 shown in FIG. 12, the control unit Psr1 sets the transport path sensors for which logs are to be acquired as the transport path sensors (St8, St5, St4, St9, St10, St11, St12, St13, St14, St15, St16, St17, St18, St19, St20, St21, St22, St23, St24, St25, St26, St27, St28, St29, St30, St31, St32, St33, St34, St35, St36, St37, St38, St39, St40, St41, St42, St43, St44, St45, St46, St47, St48, St49, St50, St51, St52, St53, St54, St55, St56, St57, St58, St59, St60, St61, St62, St63, St64, St65, St66, St67, St68, St69, St70, St71, St72, St73, St74, St75, St76, St77, St78, St79, St80, St81, St82, St83, St84, St85, St86, St87, St88, St89, St90, St91, St92, St93, St94, St95, St96, St97, St98, St99, St99, St108, St119, St129, St139, St149, St150, St169, St171, 10 , St. 11 , Sb 12 , Sb 13 , Sb 14 , Sb0, Sb 22 , Sb 23 , Sb 24 , Sb 11 , Sb 32 , Sb 33 , Sb 34 , Sb 21 , Sb 42 , Sb 43 , Sb 44 , Sb 31 , Sb 41 )) is the transport path sensor.

[0097] Then, the control unit Psr1 acquires data (banknote passing data) for the number of logs Num_DLog (in this embodiment, Num_DLog=5) for the transport path sensors that are the log acquisition targets. The log data (Num_DLog=5) of the transport path sensors that are the log acquisition targets is shown in FIG. 14. For ease of explanation, in FIG. 14, the display of log data of the transport path sensors that are not necessary to identify the remaining banknote position is omitted (in FIG. 14, the display of log data of the transport path sensors (St8, St5, St4, St9, St 10 , St. 11 , Sb0, Sb 11 , Sb 21 , Sb 31 , Sb 41 ) is displayed). In addition, in FIG. 14, the kth bill is designated as bill (k), and data indicating that bill (k) has passed is displayed as Bill (k). passed.

[0098] (Step S5): In step S5, a remaining banknote position specifying process is executed. Specifically, the following process is executed.

[0099] The control unit Psr1 identifies the position of the remaining banknotes by analyzing the log data of each transport path sensor acquired in the log acquisition process of step S4.

[0100] In the case of state 1, as shown in Fig. 14, the log data of conveyance path sensor St8 indicates that bill (8) has passed, but the log data of conveyance path sensor St5 (the next conveyance path sensor downstream of conveyance path sensor St8) indicates that bills up to bill (7) have passed, but bill (8) has not yet passed. Therefore, from the log data of the above two conveyance path sensors, the control unit Psr1 determines that bill (8) is located downstream of conveyance path sensor St8 and upstream of conveyance path sensor St5.

[0101] Also, as shown in FIG. 14, the log data of the transport path sensor St9 indicates that the bill (7) has passed through, but the transport path sensor St 10 The log data of the next transport path sensor downstream of transport path sensor St9 indicates that up to bill (6) has passed, but bill (7) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the above two transport path sensors that bill (7) is downstream of transport path sensor St9 and is not yet passed. 10 It is determined that the ionizing radiation exists upstream of the

[0102] Also, as shown in FIG. 14, the log data of the transport path sensor Sb0 indicates that the bill (6) has passed through, but the transport path sensor Sb 11 The log data of the next transport path sensor downstream of transport path sensor Sb0 indicates that bills up to bill (5) have passed, but bill (6) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the above two transport path sensors that bill (6) is downstream of transport path sensor Sb0 and is not yet passed by transport path sensor Sb0.11 It is determined that the ionizing radiation exists upstream of the

[0103] As shown in FIG. 14, the conveyance path sensor Sb 21 The log data shows that the bill (5) has passed, but the conveyance path sensor Sb 31 (Transport path sensor Sb 21 The log data of the next transport path sensor downstream of the bill (4) indicates that bill (5) has passed, but bill (4) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the two transport path sensors that bill (5) has passed through the transport path sensor Sb. 21 downstream of the conveyance path sensor Sb 31 It is determined that the ionizing radiation exists upstream of the

[0104] As a result of the above, the control unit Psr1 (1) The bill (8) remains between the transport path sensor St8 and the transport path sensor St5. (2) The bill (7) passes through the transport path sensor St9 and the transport path sensor St 10 It remains in a position between (3) The bill (6) is conveyed through the conveyance path sensor Sb0 and the conveyance path sensor Sb 11 It remains in a position between (4) The bill (5) is conveyed through the conveyance path sensor Sb 21 and transport path sensor Sb 31 It remains in a position between (See Figure 12.)

[0105] That is, the above process can accurately identify the positions of remaining banknotes in the banknote handling machine 100. Note that information on the positions of remaining banknotes can be obtained, for example, by the control unit Psr1 displaying the information on an external display device via the communication interface IF1.

[0106] Furthermore, in the banknote processing device 100, the above processing can identify whether the location of the remaining banknotes is (1) within the banknote deposit / withdrawal processing device 1 located in the upper space SPt, or (2) within the storage processing device 3 located in the lower space SPb, and therefore it can identify the entity with management authority that should take appropriate measures regarding the remaining banknotes (this information may also be displayed on an external display device by the control device Psr1 via the communication interface IF1, for example).

[0107] In the case of state 1, it is clear that (1) there are two remaining banknotes in the banknote deposit / withdrawal processing unit 1 located in the upper space SPt, and (2) there are two remaining banknotes in the storage processing unit 3 located in the lower space SPb, so the person with management authority for the banknote deposit / withdrawal processing unit 1 located in the upper space SPt and the person with management authority for the storage processing unit 3 located in the lower space SPb can take appropriate measures for each of the remaining banknotes.

[0108] <<In the case of condition 2>> The processing of steps S3 to S5 in the case of state 2 in FIG. 15 will be described.

[0109] (Step S3): In step S3, an operation mode and transport path specification process is executed. Specifically, the following process is executed.

[0110] The control unit Psr1 acquires the current operation mode of the banknote handling machine 100. In the case of state 2 shown in Fig. 15, the banknote handling machine 100 is in a state where the settlement process is being performed, so the control unit Psr1 determines that the current operation mode of the banknote handling machine 100 is a mode where the settlement process is being performed (acquires the operation mode as the operation mode for the settlement process).

[0111] Then, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process. Specifically, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process as the transport route shown in the graph in FIG.

[0112] (Step S4): In step S4, a log acquisition process is executed. Specifically, the following process is executed.

[0113] The control unit Psr1 identifies the transport path sensors installed on the transport path based on the transport path identified in step S3 (operation mode: confirmation process), and sets the identified transport path sensors as the transport path sensors for which logs are to be acquired. In the case of state 2 shown in FIG. 15, the control unit Psr1 sets the transport path sensors for which logs are to be acquired as the transport path sensors (St8, St5, St4, St9, St10, St11, St12, St13, St14, St15, St16, St17, St18, St19, St20, St21, St22, St23, St24, St25, St26, St27, St28, St29, St30, St31, St32, St33, St34, St35, St36, St37, St38, St39, St40, St41, St42, St43, St44, St45, St46, St47, St48, St49, St50, St51, St52, St53, St54, St55, St56, St57, St58, St59, St60, St61, St62, St63, St64, St65, St66, St67, St68, St69, St70, St71, St72, St73, St74, St75, St76, St77, St78, St79, St80, St81, St82, St83, St84, St85, St86, St87, St88, St89, St90, St91, St92, St93, St94, St95, St96, St97, St98, St99, St99, St108, St119, St129, St130, St140, St151, St160, St171, 10 , St. 11 , Sb 12 , Sb 13 , Sb 14 , Sb0, Sb 22 , Sb 23 , Sb 24 , Sb 11 , Sb 32 , Sb 33 , Sb 34 , Sb 21 , Sb 42 , Sb 43 , Sb 44 , Sb 31 , Sb 41 )) is the transport path sensor.

[0114] Then, the control unit Psr1 acquires data (banknote passing data) for the number of logs Num_DLog (in this embodiment, Num_DLog=5) for the transport path sensors that are the log acquisition targets. The log data (Num_DLog=5) of the transport path sensors that are the log acquisition targets is shown in FIG. 16. For ease of explanation, FIG. 16 omits the display of log data of the transport path sensors that are not necessary to identify the remaining banknote position (FIG. 16 shows only the transport path sensors (St8, St5, St4, St9, St 10 , St. 11 , Sb0, Sb 11 , Sb 21 , Sb 31 , Sb 41) log data only).

[0115] (Step S5): In step S5, a remaining banknote position specifying process is executed. Specifically, the following process is executed.

[0116] The control unit Psr1 identifies the position of the remaining banknotes by analyzing the log data of each transport path sensor acquired in the log acquisition process of step S4.

[0117] In the case of state 2, as shown in Fig. 16, the log data of conveyance path sensor St8 indicates that bill (6) has passed, but the log data of conveyance path sensor St5 (the next conveyance path sensor downstream of conveyance path sensor St8) indicates that bill (5) has passed, but bill (6) has not yet passed. Therefore, from the log data of the above two conveyance path sensors, the control unit Psr1 determines that bill (6) is located downstream of conveyance path sensor St8 and upstream of conveyance path sensor St5.

[0118] Also, as shown in FIG. 16, the log data of the transport path sensor St9 indicates that the bill (5) has passed through, but the transport path sensor St 10 The log data of the next transport path sensor downstream of transport path sensor St9 indicates that up to bill (4) has passed, but bill (5) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the above two transport path sensors that bill (5) is downstream of transport path sensor St9 and is not yet passed. 10 It is determined that the ionizing radiation exists upstream of the

[0119] As a result of the above, the control unit Psr1 (1) The bill (6) remains between the transport path sensor St8 and the transport path sensor St5. (2) The bill (5) passes through the transport path sensor St9 and the transport path sensor St 10 It remains in a position between (See Figure 15.)

[0120] That is, the above process can accurately identify the positions of remaining banknotes in the banknote handling machine 100. Note that information on the positions of remaining banknotes can be obtained, for example, by the control unit Psr1 displaying the information on an external display device via the communication interface IF1.

[0121] Furthermore, in the banknote processing device 100, the above processing can identify whether the location of the remaining banknotes is (1) within the banknote deposit / withdrawal processing device 1 located in the upper space SPt, or (2) within the storage processing device 3 located in the lower space SPb, and therefore it can identify the entity with management authority that should take appropriate measures regarding the remaining banknotes (this information may also be displayed on an external display device by the control device Psr1 via the communication interface IF1, for example).

[0122] In the case of state 2, (1) it is found that there are two remaining banknotes in the banknote deposit / withdrawal processing unit 1 located in the upper space SPt, so the entity with management authority for the banknote deposit / withdrawal processing unit 1 located in the upper space SPt can take appropriate measures regarding the remaining banknotes in the banknote deposit / withdrawal processing unit 1.

[0123] <<In the case of status 3>> The processing of steps S3 to S5 in the case of state 3 in FIG. 17 will be described.

[0124] (Step S3): In step S3, an operation mode and transport path specification process is executed. Specifically, the following process is executed.

[0125] The control unit Psr1 acquires the current operation mode of the banknote handling machine 100. In the case of state 3 shown in Fig. 17, the banknote handling machine 100 is in a state where the settlement process is being performed, so the control unit Psr1 determines that the current operation mode of the banknote handling machine 100 is a mode where the settlement process is being performed (acquires the operation mode as the operation mode for the settlement process).

[0126] Then, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process. Specifically, the control unit Psr1 specifies the transport route when the operation mode is the operation mode for the confirmation process as the transport route shown in the graph in FIG.

[0127] (Step S4): In step S4, a log acquisition process is executed. Specifically, the following process is executed.

[0128] The control unit Psr1 identifies the transport path sensors installed on the transport path based on the transport path identified in step S3 (operation mode: confirmation process), and sets the identified transport path sensors as the transport path sensors for which logs are to be acquired. In the case of state 3 shown in FIG. 17, the control unit Psr1 sets the transport path sensors for which logs are to be acquired as the transport path sensors (St8, St5, St4, St9, St10, St11, St12, St13, St14, St15, St16, St17, St18, St19, St20, St21, St22, St23, St24, St25, St26, St27, St28, St29, St30, St31, St32, St33, St34, St35, St36, St37, St38, St39, St40, St41, St42, St43, St44, St45, St46, St47, St48, St49, St50, St51, St52, St53, St54, St55, St56, St57, St58, St59, St60, St61, St62, St63, St64, St65, St66, St67, St68, St69, St70, St71, St72, St73, St74, St75, St76, St77, St78, St79, St80, St81, St82, St83, St84, St85, St86, St87, St88, St89, St90, St91, St92, St93, St94, St95, St96, St97, St98, St99, St99, St100, St111, St112, St113, St114, St115, St116, St117, 10 , St. 11 , Sb 12 , Sb 13 , Sb 14 , Sb0, Sb 22 , Sb 23 , Sb 24 , Sb 11 , Sb 32 , Sb 33 , Sb 34 , Sb 21 , Sb 42 , Sb 43 , Sb 44 , Sb 31 , Sb 41 )) is the transport path sensor.

[0129] Then, the control unit Psr1 acquires data (banknote passing data) for the number of logs Num_DLog (in this embodiment, Num_DLog=5) for the transport path sensors that are the log acquisition targets. The log data (Num_DLog=5) of the transport path sensors that are the log acquisition targets is shown in FIG. 18. For ease of explanation, FIG. 18 omits the display of log data of the transport path sensors that are not necessary to identify the remaining banknote position (FIG. 18 shows only the log data of the transport path sensors (St8, St5, St4, St9, St 10 , St. 11 , Sb0, Sb 11 , Sb 21 , Sb 31 , Sb 41 ) log data only).

[0130] (Step S5): In step S5, a remaining banknote position specifying process is executed. Specifically, the following process is executed.

[0131] The control unit Psr1 identifies the position of the remaining banknotes by analyzing the log data of each transport path sensor acquired in the log acquisition process of step S4.

[0132] In the case of state 3, as shown in FIG. 18, the log data of the transport path sensor Sb0 indicates that the bill (6) has passed through, but the transport path sensor Sb 11 The log data of the next transport path sensor downstream of transport path sensor Sb0 indicates that bills up to bill (5) have passed, but bill (6) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the above two transport path sensors that bill (6) is downstream of transport path sensor Sb0 and is not yet passed by transport path sensor Sb0. 11 It is determined that the ionizing radiation exists upstream of the

[0133] As shown in FIG. 18, the conveyance path sensor Sb 21 The log data shows that the bill (5) has passed, but the conveyance path sensor Sb 31 (Transport path sensor Sb 21The log data of the next transport path sensor downstream of the bill (4) indicates that bill (5) has passed, but bill (4) has not yet passed. Therefore, the control unit Psr1 determines from the log data of the two transport path sensors that bill (5) has passed through the transport path sensor Sb. 21 downstream of the conveyance path sensor Sb 31 It is determined that the ionizing radiation exists upstream of the

[0134] As a result of the above, the control unit Psr1 (1) The bill (6) is conveyed through the conveyance path sensor Sb0 and the conveyance path sensor Sb 11 It remains in a position between (2) The bill (5) is conveyed through the conveyance path sensor Sb 21 and transport path sensor Sb 31 It remains in a position between (See Figure 17.)

[0135] That is, the above process can accurately identify the positions of remaining banknotes in the banknote handling machine 100. Note that information on the positions of remaining banknotes can be obtained, for example, by the control unit Psr1 displaying the information on an external display device via the communication interface IF1.

[0136] Furthermore, in the banknote processing device 100, the above processing can identify whether the location of the remaining banknotes is (1) within the banknote deposit / withdrawal processing device 1 located in the upper space SPt, or (2) within the storage processing device 3 located in the lower space SPb, and therefore it can identify the entity with management authority that should take appropriate measures regarding the remaining banknotes (this information may also be displayed on an external display device by the control device Psr1 via the communication interface IF1, for example).

[0137] In the case of state 3, it is clear that there are two remaining banknotes in the storage processing unit 3 located in the lower space SPb, so the person with management authority for the storage processing unit 3 located in the lower space SPb can take appropriate measures regarding the remaining banknotes in the storage processing unit 3.

[0138] <Summary> As described above, in the banknote processing device 100, when an error occurs (when an abnormal state is detected), the operation mode is identified, the transport path in the identified operation mode is identified, and the log data of the transport path sensors present on the identified transport path is analyzed, thereby making it possible to detect the position of banknotes (transported objects) with high accuracy. The banknote processing device 100 stores and holds log data (data indicating that a banknote has passed) for each transport path sensor equal to the number of banknotes that can be present on the transport path, plus one, so when an error occurs (when an abnormal state is detected), the log data is analyzed to make it possible to identify the position of remaining banknotes with high accuracy and reliability.

[0139] Furthermore, in the banknote processing device 100, even if the management authority for each unit constituting the banknote processing device 100 is limited to different entities, when an error occurs, it is possible to determine which entity with management authority should respond by identifying the location of the remaining banknote and identifying the unit that is the target of taking measures to resolve the error. That is, in the banknote processing device 100, the housing B1 in which the banknote processing device 100 is installed is separated into an upper space SPt and a lower space SPb by a partition plate Brd1 having an opening that only allows the transport path connection unit 2 to be installed, and the banknote deposit / withdrawal processing unit 1 is installed in the upper space SPt and the storage processing unit 3 is installed in the lower space SPb. Then, in the banknote processing device 100, the above processes (abnormal state detection process, residual banknote position identification process) can accurately identify the location of the remaining banknote when an error occurs, so it is also possible to identify whether the remaining banknote is located in the banknote deposit / withdrawal processing unit 1 in the upper space SPt or in the storage processing unit 3 in the lower space SPb. If the entity with management authority over the banknote deposit / withdrawal processing unit in the upper space SPt is designated as a first entity and the entity with management authority over the storage processing unit 3 in the lower space SPb is designated as a second entity, the banknote processing device 100 can identify the location of the remaining banknote through the above process and thereby identify the entity with management authority to deal with the remaining banknote. For example, if the first entity is the store manager (the manager of the store where the banknote processing device 100 is installed) and the second entity is a cash-in-transit (CIT) company, in the banknote processing device 100, if the remaining banknote is only in the banknote deposit / withdrawal processing unit 1 in the upper space SPt, the store manager can deal with it alone, so there is no need to contact the cash-in-transit company (the second entity). On the other hand, if the remaining banknote is in the storage processing unit 3 in the lower space SPb, the second entity, the cash-in-transit company, can be contacted, and the cash-in-transit company can take action regarding the remaining banknote. In other words, the banknote processing device 100 can reduce the number of times the security company needs to be contacted to deal with the remaining banknote, thereby reducing the burden on the manager of the store where the banknote processing device 100 is installed.

[0140] As described above, in the banknote handling device 100 (a banknote handling device consisting of multiple units), when an error occurs, the position of the banknote (transported object) can be detected with high accuracy, and even if the management authority for each unit that makes up the banknote handling device is restricted to different entities, when an error occurs, the location of the remaining banknote can be identified, and the unit that is to take measures to resolve the error can be identified, thereby determining which management authority entity should respond.

Examples of computer-readable recording media include flexible disks, hard disks, CD-ROMs, MOs, DVDs, DVD-ROMs, DVD-RAMs, large-capacity DVDs, next-generation DVDs, and semiconductor memories.

[0150] The computer program is not limited to one recorded on the recording medium, but may be one transmitted via a telecommunications line, a wireless or wired communication line, a network such as the Internet, or the like.

[0151] The specific configuration of the present invention is not limited to the above-described embodiment, and various changes and modifications are possible without departing from the gist of the invention.

[0152] [Note] The present invention can also be expressed as follows.

[0153] A first invention is a paper processing apparatus including a paper input / output processing unit, a storage processing unit, a transport path connection unit, a first transport path sensor group, a second transport path sensor group, a memory unit, and a control unit.

[0154] The paper input / output processing unit has an input / output port for inputting and outputting paper sheets, a return port for returning paper sheets, and a transport path for transporting paper sheets, and performs paper sheet recognition processing, partial paper sheet reservation processing, and paper sheet input / output processing.

[0155] The storage processing unit is provided with a transport path for transporting paper sheets, and performs processing to store paper sheets input by the paper sheet input / output processing unit.

[0156] The transport path connection unit has a transport path for transporting paper sheets from the paper sheet input / output processing unit to the storage processing unit, and for transporting paper sheets from the storage processing unit to the paper sheet input / output processing unit, and connects the paper sheet input / output processing unit and the storage processing unit.

[0157] The first transport path sensor group is one or more transport path sensors that are installed on the transport path of the paper input / output processing unit and that detect the passing status of paper sheets.

[0158] The second transport path sensor group is one or more transport path sensors that are installed on the transport path of the storage processing unit and that detect the passing status of paper sheets.

[0159] The memory unit stores data indicating the passing status of paper sheets for each conveying path sensor of the first conveying path sensor group as first log data, and stores data indicating the passing status of paper sheets for each conveying path sensor of the second conveying path sensor group as second log data.

[0160] The control unit performs processing to identify the positions of remaining pieces of paper (for example, banknotes) by analyzing the first log data and the second log data stored in the storage unit.

[0161] In this paper processing device, data (log data) indicating the passage status of paper sheets is stored and maintained in a memory unit for each transport path sensor installed on the transport path.Therefore, when an error occurs (when an abnormal condition is detected), for example, the operating mode is identified, the transport path in the identified operating mode is identified, and the log data of the transport path sensors present on the identified transport path is analyzed, thereby making it possible to detect the position of paper sheets (e.g., banknotes) with high accuracy.

[0162] It should be noted that the term "paper" is not limited to banknotes, but also includes vouchers, securities, tickets, etc.

[0163] The second invention is the first invention, further comprising a third transport path sensor group, which is one or more transport path sensors installed in the transport path of the transport path connection section and which detects the passing status of paper sheets.

[0164] The storage unit stores data indicating the passing status of paper sheets for each of the transport path sensors of the third transport path sensor group as third log data.

[0165] The control unit performs processing to identify the positions of remaining banknotes by analyzing the first log data, the second log data, and the third log data stored in the storage unit.

[0166] This allows the paper processing device to analyze the log data of the transport path sensor installed in the transport path of the transport path connection section, and to identify the position of remaining banknotes with high accuracy.

[0167] The third invention is the first or second invention, further comprising a housing and a partition plate member that separates the housing into a first space and a second space, the partition plate member having an opening for arranging a transport path connection portion.

[0168] The paper input / output processing unit is installed in the first space.

[0169] The storage processing section is installed in the first space.

[0170] The transport path connecting portion is installed so as to pass through the opening of the partition plate member.

[0171] As a result, in this paper processing apparatus, the paper input / output processing unit and the storage processing unit can be installed in different spaces. For example, a management authority entity that can access the paper input / output processing unit in the first space (referred to as the first entity) can be separated from a management authority entity that can access the storage processing unit in the second space (referred to as the second entity), and when an abnormal state occurs in the paper processing apparatus (when a problem occurs), the entity that handles the problem can be separated. For example, when the paper processing apparatus detects that there are residual banknotes in the paper input / output processing unit in the first space, the first entity can be made to handle the residual banknotes, and on the other hand, when the paper processing apparatus detects that there are residual banknotes in the storage processing unit in the second space, the second entity can be made to handle the residual banknotes.

[0172] The fourth invention is the third invention, in which the control unit determines the maximum possible number Nmax of sheets remaining in the paper processing device based on the total length, which is the sum of the length of the conveying path of the paper input / output processing unit, the length of the conveying path of the conveying path connection unit, and the length of the conveying path of the storage processing unit, the minimum input period of sheets when inputting sheets into the paper input / output processing unit, and the conveying speed of the conveying path of the paper input / output processing unit, the conveying path of the conveying path connection unit, and the conveying path of the storage processing unit.

[0173] The storage unit stores and holds, as log data, data indicating the passing status of the maximum number Nmax+1 pieces of paper for each transport path sensor installed in the paper processing device.

[0174] The control unit then analyzes the log data to perform processing to identify the positions of remaining banknotes.

[0175] In this paper processing device, log data (data indicating that a banknote has passed) equal to the number of banknotes that can be present on the transport path plus one item is stored in a memory unit for each transport path sensor.Therefore, when an error occurs (when an abnormal condition is detected), the location of remaining banknotes can be identified with high accuracy and reliability by analyzing the log data.

[0176] Furthermore, in this paper handling device, even if the management authority for each unit that makes up the paper handling device is limited to different entities, when an error occurs, it is possible to determine which management authority entity should respond by identifying the location of the remaining banknotes and identifying the unit that will take measures to resolve the error.

[0177] A fifth aspect of the present invention is a paper processing method executed by using the paper processing device of the fourth aspect of the present invention, and includes a log data reading processing step and a remaining banknote position specifying processing step.

[0178] The log data reading processing step reads out a maximum number Nmax+1 of first log data, a maximum number Nmax+1 of second log data, and a maximum number Nmax+1 of third log data stored in the storage unit.

[0179] The remaining banknote position specifying process step performs a process of specifying the positions of banknotes remaining in the paper processing device by analyzing the log data read out in the log data reading process step.

[0180] In this paper processing method, when an error occurs (when an abnormal state is detected), log data (data indicating that a banknote has passed) equal to the number of banknotes that can be present on the transport path + 1 is read from the memory unit for each transport path sensor, and the read log data is analyzed, making it possible to accurately and reliably identify the location of remaining banknotes.

[0181] The log data reading processing step and the remaining banknote position identification processing step may each be realized (performed) using, for example, one or more processors and / or one or more memories accessible from one or more processors.

[0182] A sixth aspect of the present invention is a program for causing a computer to execute the paper processing method of the fifth aspect of the present invention.

[0183] This makes it possible to realize a program for causing a computer to execute a paper processing method that has the same effects as the fifth aspect of the present invention. [Explanation of symbols]
