  Further, the authenticity detection unit 116b detects the authenticity of the paper sheet P based on the feature amount acquired from the paper sheet P. That is, the authenticity detection unit 116b determines whether the paper sheet P is a genuine ticket or a counterfeit.

  Further, the fitness detection unit 116c detects the fitness of the paper sheet P based on the feature amount acquired from the paper sheet P. That is, the damage detection unit 116c determines whether the paper sheet P is a correct sheet that can be recirculated (fit sheet for recirculation) or a non-reflowable sheet (unfit sheet for recirculation). To do.

  The ticket type detection unit 116 a, authenticity detection unit 116 b, and fitness detection unit 116 c supply detection results to the detection information processing unit 152. The detection information processing unit 152 integrates the detection results supplied from the ticket type detection unit 116a, the authenticity detection unit 116b, and the fitness detection unit 116c. Thereby, the detection information processing unit 152 can recognize the detection result of the bill type, authenticity, and correctness for each paper sheet P. The detection information processing unit 152 determines the transport destination (stacking unit) of the paper sheet P based on the recognized ticket type, authenticity, and correctness for each paper sheet P.

  The accumulation units are, for example, the accumulation units 128 to 131, the cutting unit 133, and the exclusion accumulation unit 134.

  The ticket type detection unit 116a, the authenticity detection unit 116b, the damage detection unit 116c, and the detection information processing unit 152 are connected by a transmission path such as a bus, for example. The ticket type detection unit 116a, the authenticity detection unit 116b, and the fitness detection unit 116c transmit the detection result to the detection information processing unit 152 via the transmission path.

  For example, the detection information processing unit 152 determines the transport destination so that the paper sheet P detected as a genuine note is transported to the stacking units 128 to 131. Note that the stacking units 128 to 131 are provided for each type of paper sheet P. That is, one stacking unit is provided so as to correspond to a certain type of paper sheet P. The detection information processing unit 152 specifies the transport destination of the paper sheet P from the stacking units 128 to 131 according to the ticket type of the paper sheet P.

  The detection information processing unit 152 determines the transport destination so that the paper sheet P detected as a ticket is transported to the cutting unit 133. The cutting unit 133 is a stacking unit that stacks the cut paper sheets P. The cutting unit 133 includes a cutting machine 133a and a stacker 133b. The cutting machine 133a of the cutting unit 133 cuts the conveyed slip. The cutting unit 133 accumulates the cut pieces of the paper sheet P in the stacker 133b. The stacker 133b includes a take-out port from which a piece of paper can be removed from the outside. That is, the operator can take out the paper pieces of the paper sheets P accumulated in the stacker 133b cut from the take-out port.

  The detection information processing unit 152 determines whether or not the paper sheet P should be excluded. The detection information processing unit 152 determines that the paper sheet P detected to be a fake ticket, the paper sheet P in which an overlap is detected, or the paper sheet P that cannot be determined to be a rejection ticket. .

  In addition, the detection information processing unit 152 has a short pitch in which detection by each detector is not correctly performed due to a short interval between the front paper sheet P and the back paper sheet P in the transport path. The class P is determined as an exclusion ticket.

  The detection information processing unit 152 determines the transport destination so that the paper sheet P determined to be the rejection ticket is transported to the rejection stacking unit 134. The cutting unit 133 is a stacking unit that stacks the paper sheets P determined to be an exclusion ticket. The exclusion stacking unit 134 is configured so that the operator can take out the stacked paper sheets P.

  The paper sheet processing apparatus 100 controls operations of the transport path 115 and a plurality of gates so that the paper sheet P is transported to the transport destination determined by the detection information processing unit 152. A plurality of gates (not shown) are provided on the conveyance path 115 on the downstream side of the inspection unit 116. Each of the gates is controlled by the main control unit 151. The main control unit 151 controls the operation of each gate based on the determination result by the detection information processing unit 152. As a result, the main control unit 151 performs control so that the paper sheet P conveyed through the conveyance path 115 is conveyed to a predetermined processing unit. Further, the paper sheet processing apparatus 100 can stack the paper sheets P in the transport destination determined by the detection information processing unit 152.

  The operator can arbitrarily set the type (ticket type) of the paper sheet P to be processed by the paper sheet processing apparatus 100 by operating the operation display unit 137 or the like.

  The main control unit 151 stores the count result of the paper sheets P conveyed to the stacking unit 132 or the cutting unit 133 as the inspection result in association with each bundle of paper sheets. The main control unit 151 transmits the inspection result to the server.

  The inspection unit 116 starts the process when the paper sheet P reaches the determination start position shown in FIG. The inspection unit 116 includes a sensor (not shown) that detects that the paper sheet P has reached the determination start position. The inspection unit 116 determines whether the paper sheet P has reached the determination start position based on the detection result of the sensor.

  When the inspection unit 116 detects that the paper sheet P has reached the determination start position, the inspection unit 116 places the ticket type detection unit 116a, the authenticity detection unit 116b, and the damage detection unit 116c in a standby state. The ticket type detection unit 116a, the authenticity detection unit 116b, and the damage detection unit 116c acquire feature amounts from the paper sheet P when the paper sheet P reaches the respective detection positions.

  For example, the ticket type detection unit 116a can acquire the feature amount from the paper sheet P when the paper sheet P reaches the first detection position. The ticket type detection unit 116a detects the ticket type of the paper sheet P based on the feature amount acquired from the paper sheet P. The ticket type detection unit 116a transmits the detection result (ticket type detection data) to the detection information processing unit 152 via the transmission path.

  Further, for example, the authenticity detection unit 116b can acquire a feature amount from the paper sheet P when the paper sheet P reaches the second detection position. The authenticity detection unit 116b detects the authenticity of the paper sheet P based on the feature amount acquired from the paper sheet P. The authenticity detection unit 116b transmits the detection result (authentication detection data) to the detection information processing unit 152 via the transmission path.

  Further, for example, the damage detection unit 116c can acquire a feature amount from the paper sheet P when the paper sheet P reaches the third detection position. The damage detection unit 116c detects the damage of the paper sheet P based on the feature amount acquired from the paper sheet P. The damage detection unit 116c transmits the detection result (loss detection data) to the detection information processing unit 152 via the transmission path.

  Based on the ticket type detection data, authenticity detection data, and damage detection data transmitted from the ticket type detection unit 116a, the authenticity detection unit 116b, and the damage detection unit 116c, the detection information processing unit 152 The transport destination of the class P is determined. The detected information processing unit 152 determines the transport destination of the paper sheet P until the paper sheet P reaches the final determination position shown in FIG.

  An error (communication error) may occur during transmission of the detection result. Therefore, each unit of the inspection unit 116 adds an error detection code such as a checksum, CRC, and hash value to data to be transmitted. That is, the ticket type detection unit 116 a adds an error detection code to the ticket type detection data and transmits it to the detection information processing unit 152. In addition, the authenticity detection unit 116 b adds an error detection code to the authenticity detection data and transmits it to the detection information processing unit 152. In addition, the damage detection unit 116 c adds an error detection code to the damage detection data and transmits it to the detection information processing unit 152.

  When the detection information processing unit 152 receives the detection result, the detection information processing unit 152 uses the error detection code to determine whether a communication error has occurred during transmission of the detection result. That is, the detection information processing unit 152 can determine whether or not a communication error has occurred during transmission of the ticket type detection data, authenticity detection data, and damage detection data.

  Furthermore, if the detection information processing unit 152 determines that a communication error has occurred during transmission of the detection result, the detection information processing unit 152 may request each unit of the inspection unit 116 to retransmit the detection result in which the communication error has occurred. it can.

  Furthermore, the detection information processing unit 152 determines which position on the transport path the paper sheet P is based on the elapsed time after the paper sheet P reaches the determination start position and the transport speed of the paper sheet P. Can be recognized sequentially. Furthermore, the detection information processing unit 152 can sequentially recognize the time until the paper sheet P reaches the final determination position.

  Each unit of the inspection unit 116 packetizes detection result data and transmits the packet to the detection information processing unit 152. That is, each unit of the inspection unit 116 transmits data in a state where the detection result is divided into a plurality of packets to the detection information processing unit 152. The detection information processing unit 152 can identify a packet in which a communication error has occurred based on the error detection code. Furthermore, the detection information processing unit 152 can request each unit of the inspection unit 116 to retransmit a packet identified as having a communication error.

  In addition, each unit of the inspection unit 116 is arranged in the order of, for example, a ticket type detection unit 116a, a true / false detection unit 116b, and a fitness detection unit 116c from the upstream side. However, ticket type detection data, authenticity detection data. And the loss detection data has different data capacities. For this reason, the order in which the detection information processing unit 152 receives the detection data is undefined. In addition, arrangement | positioning of each part of the test | inspection part 116 of FIG. 2 is an example, and may be arrange | positioned in what order.

FIG. 3 shows an example of the operation of the paper sheet processing apparatus 100.
First, when the detection information processing unit 152 of the main control unit 151 detects that the paper sheet P has reached the determination start position, the detection information processing unit 152 controls the inspection unit 116 to start the inspection. In this case, the detection information processing unit 152 requests detection data from the inspection unit 116 (step S11).

  First, the ticket type detection unit 116a of the inspection unit 116 detects the ticket type of the paper sheet P. The ticket type detection unit 116 a transmits the ticket type detection data to the detection information processing unit 152. The detection information processing unit 152 receives the ticket type detection data (step S12).

  The detection information processing unit 152 determines whether a communication error has occurred during transmission of the ticket type detection data (step S13). That is, the detection information processing unit 152 detects whether or not a communication error is included in the received ticket type detection data using the error detection code of the received ticket type detection data.

  Further, the detection information processing unit 152 calculates the data arrival time (step S14). The data arrival time indicates the time from when the paper sheet P reaches the determination start position until the transmission of the detection data is completed. That is, the data arrival time in this case indicates the time from when the paper sheet P reaches the determination start position to when the transmission of the ticket type detection data is completed.

  The authenticity detection unit 116b of the inspection unit 116 detects the authenticity of the paper sheet P. The authenticity detection unit 116 b transmits authenticity detection data to the detection information processing unit 152. The detection information processing unit 152 receives authenticity detection data (step S15).

  The detection information processing unit 152 determines whether a communication error has occurred during transmission of the authenticity detection data (step S16). That is, the detection information processing unit 152 detects whether or not a communication error is included in the received true / false detection data using the error detection code of the received true / false detection data.

  Further, the detection information processing unit 152 calculates the data arrival time (step S17). The data arrival time in this case indicates the time from when the paper sheet P reaches the determination start position until the transmission of the authenticity detection data is completed.

  The damage detection unit 116c of the inspection unit 116 detects the authenticity of the paper sheet P. The fitness detection unit 116 c transmits the fitness detection data to the detection information processing unit 152. The detection information processing unit 152 receives the damage detection data (step S18).

  The detection information processing unit 152 determines whether a communication error has occurred during transmission of the damage detection data (step S19). That is, the detection information processing unit 152 detects whether or not a communication error is included in the received damage detection data using the error detection code of the received damage detection data.

  Furthermore, the detection information processing unit 152 calculates the data arrival time (step S20). The data arrival time in this case indicates the time from when the paper sheet P reaches the determination start position until the transmission of the damage detection data is completed.

  The detection information processing unit 152 recognizes the received ticket type detection data, authenticity detection data, and damage detection data. Thereby, the detection information processing part 152 can recognize the bill type, authenticity, and correctness of the paper sheet P, respectively.

  The detection information processing unit 152 waits for completion of reception of all detection data. When the detection information processing unit 152 recognizes that reception of all detection data is completed, the detection information processing unit 152 recognizes the time when reception of each detection data is completed. Thereby, the detection information processing unit 152 recognizes the order in which each detection data is received.

  The detection information processing unit 152 determines whether or not there is a communication error in the first received detection data (step S21). Furthermore, when the detection information processing unit 152 determines that the first received detection data has a communication error, the detection information processing unit 152 determines whether the detection data can be retransmitted (step S22). If it is determined that the detection data can be retransmitted, the detection information processing unit 152 requests the inspection unit 116 to retransmit the first received detection data (step S23).

  Next, the detection information processing unit 152 determines whether or not there is a communication error in the second received detection data (step S24). Furthermore, if the detection information processing unit 152 determines that the second received detection data has a communication error, the detection information processing unit 152 determines whether the detection data can be retransmitted (step S25). If it is determined that the detection data can be retransmitted, the detection information processing unit 152 requests the inspection unit 116 to retransmit the second received detection data (step S26).

  Next, the detection information processing unit 152 determines whether or not there is a communication error in the third received detection data (step S27). Furthermore, when the detection information processing unit 152 determines that there is a communication error in the third received detection data, the detection information processing unit 152 determines whether the detection data can be retransmitted (step S28). If it is determined that the detection data can be retransmitted, the detection information processing unit 152 requests the inspection unit 116 to retransmit the third received detection data (step S29).

  The detection information processing unit 152 determines whether or not the transmission of detection data has been completed (step S30). That is, the detection information processing unit 152 determines whether there is detection data that is being transmitted. For example, the detection information processing unit 152 determines whether or not the transmission of the first detection data or the transmission of the detection data requested to be retransmitted is completed. When it is determined that the transmission of the detection data has not been completed, the detection information processing unit 152 proceeds to a process subsequent to step S11 and continues to transmit the detection data.

  When it is determined that the transmission of the detection data has been completed, the detection information processing unit 152 determines the transport destination of the paper sheet P using each received detection data (step S31). That is, the detection information processing unit 152 determines the transport destination of the paper sheet P based on the ticket type detection data, authenticity detection data, and damage detection data. The paper sheet processing apparatus 100 transports the paper sheet P to the transport destination determined by the detection information processing unit 152. Thereby, the paper sheet processing apparatus 100 can classify the paper sheet P based on various detection results.

  FIG. 4 shows an example of processing such as step S22, step S25, and step S28 in FIG.

  The detection information processing unit 152 calculates the capacity of detection data including a communication error, that is, the capacity of data that needs to be retransmitted (retransmission data) (step S41). For example, the detection information processing unit 152 requests retransmission of a packet in which a communication error has occurred in the detection data. For this purpose, the detection information processing unit 152 calculates the capacity of a packet including a communication error.

  Furthermore, the detection information processing unit 152 calculates a time required for retransmission (retransmission time) based on the calculated capacity (step S42). That is, the detection information processing unit 152 calculates a time required for retransmission of retransmission data.

  Further, the detection information processing unit 152 sequentially calculates the transport position of the paper sheet P (step S43). For example, the detection information processing unit 152 determines the position of the paper sheet P on the conveyance path based on the elapsed time after the paper sheet P reaches the determination start position and the conveyance speed of the paper sheet P. Can be identified.

  Furthermore, the detected information processing unit 152 calculates the time (arrival time) until the paper sheet P reaches the final determination position (step S44). For example, the detection information processing unit 152 is based on the elapsed time after the paper sheet P reaches the determination start position, the transport speed of the paper sheet P, and the distance between the determination start position and the final determination position. The time until the paper sheet P reaches the final determination position can be calculated.

  The detection information processing unit 152 calculates the difference between the retransmission time and the arrival time (step S45). For example, the detection information processing unit 152 calculates a difference in retransmission time with respect to arrival time. When the retransmission time is less than the arrival time, retransmission of the retransmission data is not completed before the paper sheet P reaches the final determination position. That is, the detection information processing unit 152 determines whether or not retransmission of retransmission data is completed before the paper sheet P reaches the final determination position by calculating a difference between the retransmission time and the arrival time. Can do.

  First, the detected information processing unit 152 determines whether or not the difference between the retransmission time and the arrival time is “0” or more (step S46). Thereby, the detection information processing unit 152 determines whether or not the retransmission of the retransmission data is completed before the paper sheet P reaches the final determination position. When the difference is “0” or more, the detection information processing unit 152 determines that retransmission is possible.

  When the difference is less than “0”, that is, when the arrival time is less than the retransmission time, the detection information processing unit 152 recognizes that retransmission of the retransmission data is impossible (step S47). In this case, the detected information processing unit 152 determines NO in steps S22, S25, and S28 in FIG. In this case, the detection information processing unit 152 proceeds to subsequent processing without requesting retransmission of the detection data.

  For example, the detection information processing unit 152 may be configured to shift to the process of step S30 when it is determined NO in steps S22, S25, and S28 of FIG. Thereby, the detection information processing unit 152 can omit unnecessary determination processing and the like. If the detection information processing unit 152 determines NO in steps S22, S25, and S28 in FIG. 3, the detection information processing unit 152 determines the transport destination of the paper sheet P using the detection data that has already been received. For example, it is assumed that ticket type detection data and authenticity detection data are received, a communication error occurs during transmission of the damage detection data, and retransmission is impossible. In this case, the detection information processing unit 152 determines the transport destination of the paper sheet P using the ticket type detection data and the authenticity detection data. That is, when it is impossible to retransmit the retransmission data, the detection information processing unit 152 determines the transport destination of the paper sheet P using the detection data that has been received.

  When it is determined in step S46 that the difference is “0” or more, that is, when the arrival time is equal to or longer than the retransmission time, the detection information processing unit 152 recognizes that retransmission data can be retransmitted. Furthermore, the detection information processing unit 152 determines whether or not the difference in the retransmission time with respect to the arrival time is “difference> 0” (step S48). Thereby, the detection information processing unit 152 recognizes whether or not retransmission data can be retransmitted and there is a delay before the paper sheet P reaches the final determination position.

  If it is determined in step S48 that “difference> 0”, the detected information processing unit 152 can retransmit the retransmitted data, and there is a delay before the paper sheet P reaches the final determination position. Recognize (step S49). Further, when it is determined in step S48 that “difference> 0” is not satisfied, the detected information processing unit 152 can retransmit the retransmitted data, and there is a delay until the paper sheet P reaches the final determination position. (Step S50).

  Through the above processing, the detection information processing unit 152 can recognize whether or not retransmission of retransmission data is possible. Furthermore, the detection information processing unit 152 can recognize whether or not there is a delay before the paper sheet P reaches the final determination position when the retransmission data can be retransmitted. Accordingly, the detection information processing unit 152 can recognize whether or not there is a time required for retransmission when communication errors are included in other detection data.

  As described above, when the detected information processing unit 152 determines that there is no time required for retransmission, the detection information processing unit 152 proceeds to step S30 in FIG. Furthermore, the detection information processing unit 152 determines that the transmission is completed in step S30. As a result, the detection information processing unit 152 does not need to make unnecessary determinations when there is no time to retransmit retransmission data.

  As described above, the detection information processing unit 152 determines whether or not retransmission data can be retransmitted based on the conveyance position of the paper sheet P, the conveyance speed of the paper sheet P, and the capacity of the retransmission data. judge. The detection information processing unit 152 obtains retransmission data when retransmission is possible, and uses it to determine the transport destination of the paper sheet P. As a result, it is possible to provide a paper sheet processing apparatus and a paper sheet processing method that can more reliably sort paper sheets.
