The conveyance state of a bill is determined.

  For example, the conveyance state determination unit 601 determines that the conveyance state of the banknote is abnormal when any of the conveyance unit sensors is continuously in the ON state for the first determination time or longer. The first determination time is a time obtained by dividing the length of the bill in the conveyance direction by the conveyance speed. A plurality of banknotes partially stacked on each other have an apparent total length. Thereby, the state in which the some banknote partially laminated | stacked mutually is conveyed can be determined as an abnormal state.

  In addition, the conveyance state determination unit 601 determines that the conveyance state is abnormal, for example, when the time during which any one of the conveyance unit sensors is continuously ON is shorter than the first determination time. The folded bill is apparently shorter in overall length. Thereby, the state in which the folded banknote is conveyed can be determined as an abnormal state.

  In addition, the conveyance state determination unit 601 performs the second operation after one of the two conveyance unit sensors arranged at intervals in the width direction of the conveyance unit 107 is switched from the OFF state to the ON state, for example. When the determination time continues and the other banknote sensor is in the OFF state, it is determined that the conveyance state is abnormal. When the bill is inclined with respect to the carrying direction, the bill may be hindered when it is larger than a threshold value. The second determination time is a time obtained by multiplying the tangent of the threshold by the distance between the two bill sensors. Thereby, the state in which the banknote inclined with respect to the conveyance direction is conveyed to such a degree that it may interfere with conveyance of a banknote can be determined as an abnormal state.

(Memory part)
The storage unit 603 stores information referred to for control by the control device 600. For example, the storage unit 603 stores setting values for each determination time used in the conveyance state determination by the conveyance state determination unit 601 and information displayed on the display unit 121 and the like by the control unit 605.

(Control part)
The control unit 605 includes a conveyance control unit 651 that controls conveyance of banknotes by the conveyance unit 107, and a notification control unit 653 that controls notification of predetermined information to the user.

  The conveyance control unit 651 controls conveyance of banknotes by the conveyance unit 107. Specifically, the conveyance control unit 651 controls the conveyance of banknotes by the conveyance unit 107 by controlling the rotation of a drive motor for driving each roller that conveys the banknotes provided in the conveyance unit 107.

  The conveyance control unit 651 performs stop control to stop conveyance of banknotes by the conveyance unit 107 when the conveyance state determination unit 601 determines that the conveyance state is abnormal. Further, after the stop control is performed by the conveyance control unit 651, the control unit 605 retracts the bill press 503 in a direction away from the pickup roller 505.

  When the conveyance control unit 651 acquires detection information indicating that no banknotes are stored in the storage unit 501 after the conveyance of the banknotes by the transfer unit 107 is stopped by the stop control, the transfer control unit 651 transfers the transfer state determination unit to the transfer unit 107. The banknote (abnormal banknote) determined to be abnormal by 601 is conveyed (returned) to the storage unit 501.

  The detection information may be obtained based on detection of whether or not a bill is stored in the storage unit 501 by the storage unit sensor 551. Specifically, when the conveyance control unit 651 acquires information indicating that the storage unit sensor 551 is in the OFF state, the conveyance control unit 651 causes the conveyance unit 107 to perform conveyance again. Thereby, it is possible to reduce time and labor for the operator to check whether or not banknotes are stored in the storage unit 501.

  Moreover, the said detection information may be input into the cash processing apparatus 1 by the operator. Specifically, the detection information is input to the cash processing apparatus 1 when the operator presses the operation button 119 shown in FIG. Thereby, the detection information which shows that the banknote is not accommodated in the accommodating part 501 can be acquired by the cheaper method which does not use an accommodating part sensor.

  The conveyance control unit 651 causes the conveyance unit 107 to return and convey the paper when the storage unit sensor 551 is in the ON state after a predetermined time has elapsed after the conveyance of the banknotes by the conveyance unit 107 is stopped by the stop control. May be. Thereby, the delay of the transaction by the banknote accommodated in the accommodating part 501 not being removed for a long time can be suppressed.

  The conveyance control unit 651 determines that the conveyance state of the conveyance unit 107 is abnormal by the conveyance state determination unit 601 at a conveyance speed slower than the conveyance speed of the banknotes before the conveyance of the banknotes by the conveyance unit 107 is stopped by the stop control. The bills may be transported to the storage unit 501. Thereby, since the movement speed of the abnormal banknote when an abnormal banknote is discharged | emitted from the inside of the cash processing apparatus 1 to the accommodating part 501 can be reduced, it can suppress that the said abnormal banknote scatters.

  The conveyance control unit 651 starts the return conveyance of the abnormal banknote, and when the first conveyance unit sensor 553, the second conveyance unit sensor 555, and the third conveyance unit sensor 557 are all in the OFF state, The conveyance of the banknote by the conveyance unit 107 is stopped.

  In addition, after the return conveyance is started, the conveyance control unit 651 is in a state where any one or more of the first conveyance unit sensor 553, the second conveyance unit sensor 555, and the third conveyance unit sensor 557 are in an ON state. When a certain state has passed for a predetermined time, the conveyance of banknotes by the conveyance unit 107 may be stopped. Thereafter, the processing by the cash processing apparatus 1 ends with an error. The predetermined time is a time obtained by dividing the conveyance speed in the conveyance back to the length of the conveyance unit 107 from the high-speed conveyance roller 515 to the storage unit 501. Thereby, generation | occurrence | production of the operation | movement error of the cash processing apparatus 1 in a return conveyance is detectable.

  When the conveyance state determination unit 601 determines that the conveyance state is abnormal, the notification control unit 653 controls notification of predetermined information to the operator. For example, when the conveyance state determination unit 601 determines that the conveyance state is abnormal, the notification control unit 653 performs stop control by the conveyance control unit 651, and after the bill press 503 is retracted, Controls notification to the operator. The notification control unit 653 may determine whether or not an operation error of the bill press 503 has occurred when the bill press 503 is retracted. When it is determined that the operation error of the bill press 503 has not occurred, the notification control unit 653 controls notification of predetermined information to the operator. On the other hand, when it determines with the operation | movement error of the bill press 503 having arisen by the alerting | reporting control part 653, the process by the cash processing apparatus 1 complete | finishes an error.

  For example, the notification control unit 653 controls the notification of the predetermined information to the operator by controlling the display of the predetermined information. Specifically, the notification control unit 653 shows a message for prompting the removal of the banknote stored in the storage unit 603 when the conveyance state determination unit 601 determines that the conveyance state is abnormal, as shown in FIG. Displayed on the display unit 121 and the host system (not shown). Thus, before the abnormal banknote is returned and conveyed, it is possible to notify the operator that the conveyance state is abnormal by presenting a predetermined sentence or image to the operator. Therefore, the removal of the banknotes stored in the storage unit 501 by the operator can be promoted before the abnormal banknotes are returned and conveyed.

  Further, the notification control unit 653 may control notification of predetermined information to the operator by blinking or lighting a button for receiving an instruction from the operator. Specifically, when the conveyance state determination unit 601 determines that the conveyance state is abnormal, the notification control unit 653 blinks or lights the operation button 119 illustrated in FIG. Thus, before the abnormal banknote is returned and conveyed, it is possible to notify the operator that the conveyance state is abnormal by presenting a visual stimulus different from the normal time. Therefore, the removal of the banknotes stored in the storage unit 501 by the operator can be promoted before the abnormal banknotes are returned and conveyed.

  In addition, the notification control unit 653 may notify the operator of predetermined information when the conveyance of the banknote by the conveyance unit 107 is stopped after the abnormal conveyance of the abnormal banknote is performed. Specifically, in such a case, the notification control unit 653 causes the display unit 121 shown in FIG. 2 or a host system (not shown) to display a message that prompts the removal of the banknote stored in the storage unit 603. Alternatively, the operation button 119 shown in FIG. 2 may be blinked or lit.

  FIG. 11 is an explanatory diagram for explaining a return from a conveyance abnormality by the cash processing apparatus 1 according to the embodiment of the present invention. When the conveyance state determination unit 601 determines that the conveyance state is abnormal, the conveyance control unit 651 stops the conveyance of banknotes by the conveyance unit 107. And as shown to d of FIG. 11, the banknote B2 currently conveyed by the conveyance part 107 stops in the cash processing apparatus 1. FIG. Next, as shown in e of FIG. 11, the bill press 503 moves in a direction away from the pickup roller 505. And according to the cash processing apparatus 1 which concerns on this invention, the message which prompts the removal of a banknote by the alerting | reporting control part 653 is displayed on the display part 121 shown, for example in FIG. 2, and as shown to f of FIG. The bundle of bills B1 stored in the storage unit 501 by the operator is removed. And since the accommodating part sensor 551 will be in an OFF state, the conveyance control part 651 makes the conveyance part 107 return and convey. Therefore, as shown in g of FIG. 11, the abnormal banknote B <b> 2 is transported to the storage unit 501 by the transport unit 107.

  When the abnormal banknote B2 in the cash processing apparatus 1 is returned and conveyed to the storage unit 501 in the return from the conveyance abnormality by the cash processing apparatus 1 according to the embodiment of the present invention, the storage unit 501 includes As shown in g, the banknote bundle B1 is not accommodated. Therefore, it can suppress that abnormal banknote B2 collides with bundle B1 of banknotes, and some banknotes B3 of bundle B1 of banknotes are scattered. Therefore, banknote management can be facilitated.

[3-2. Return processing from conveyance error performed by the control unit]
Next, the flow of return processing from a conveyance abnormality performed by the control device 600 according to the present invention will be described.

  FIG. 12 is a flowchart illustrating an example of a flow of return processing from a conveyance abnormality performed by the control device 600 according to the embodiment of the invention. The process shown in FIG. 12 is started when the conveyance state determination unit 601 determines that the conveyance state is abnormal. When the conveyance state determination unit 601 determines that the conveyance state is abnormal, the conveyance control unit 651 performs stop control for stopping conveyance of the banknotes by the conveyance unit 107 (step S702). Then, the bill press 503 is retracted in a direction away from the pickup roller 505 (step S704).

  Next, the notification control unit 653 determines whether or not the bill press 503 has retreated without causing an operation error (step S706). When it is determined by the notification control unit 653 that an operation error of the bill press 503 has occurred when the bill press 503 is retracted (step S706 / YES), the processing shown in FIG. On the other hand, when it is determined by the notification control unit 653 that an operation error of the bill press 503 has not occurred when the bill press 503 is retracted (step S706 / NO), the notification control unit 653 displays a message prompting the removal of the banknote, for example. It is displayed on the part 121 (step S708).

  Next, the conveyance control unit 651 determines whether or not the storage unit sensor 551 is in an OFF state (step S710). When it is determined that the storage unit sensor 551 is in the OFF state (step S710 / YES), the transport control unit 651 causes the transport unit 107 to transport the abnormal banknote to the storage unit 501 (step S712). On the other hand, when it is determined that the storage unit sensor 551 is not in the OFF state (step S710 / NO), the conveyance control unit 651 determines whether a predetermined time has elapsed (step S714). When it is determined by the transfer control unit 651 that the predetermined time has not elapsed (step S714 / NO), the process returns to step S710 to determine the ON / OFF state of the storage unit sensor 551. On the other hand, when it is determined by the transport control unit 651 that a predetermined time has elapsed (step S714 / YES), the process proceeds to step S712, and the return transport is performed.

  Then, the conveyance control unit 651 determines whether or not all of the first conveyance unit sensor 553, the second conveyance unit sensor 555, and the third conveyance unit sensor 557 are in the OFF state (step S716). Here, the determination of the determination process in step S716 may be performed constantly or every time a predetermined time elapses. The predetermined time is a time obtained by returning the length of the transport unit 107 from the high-speed transport roller 515 to the storage unit 501 and dividing the transport speed in transport, and the abnormal banknote in the cash processing apparatus 1 is stored in the storage unit 501. This time is estimated to be sufficient as the time for being transported to Thereby, the burden of the determination process of step S716 can be reduced.

  If it is determined that all the transport unit sensors are in the OFF state (step S716 / YES), the transport control unit 651 stops the transport of banknotes by the transport unit 107 (step S718). On the other hand, when it is determined that any one or more of the above-described transport unit sensors are in the ON state (step S716 / NO), the transport control unit 651 determines whether a predetermined time has elapsed (step S720). When it is determined that the predetermined time has elapsed (step S720 / YES), the conveyance control unit 651 stops the conveyance of banknotes by the conveyance unit 107 (step S722). Then, the process shown in FIG. 12 ends with an error. On the other hand, if it is determined by the transfer control unit 651 that the predetermined time has not elapsed (step S720 / NO), the process returns to step S716 to determine the ON / OFF state of the transfer unit sensor.

  If conveyance of the banknote by the conveyance part 107 stops in step S718, the alerting | reporting control part 653 will display the message which accelerates | stimulates removal of a banknote, for example on the display part 121 (step S724). Then, the control unit 605 determines whether or not the storage unit sensor is in an OFF state (step S726). When it is determined by the control unit 605 that the storage unit sensor is in the OFF state (step S726 / YES), the process illustrated in FIG. 12 is terminated, and the deposit transaction is resumed or terminated. For example, a message that prompts re-insertion of deposited banknotes is displayed on the display unit 121. On the other hand, when it determines with the accommodating part sensor not being an OFF state (step S726 / NO), the control part 605 determines whether predetermined time passed (step S728). When it is determined by the control unit 605 that the predetermined time has not elapsed (step S728 / NO), the process returns to step S726 to determine the ON / OFF state of the storage unit sensor. On the other hand, when it is determined by the control unit 605 that the predetermined time has elapsed (step S728 / YES), the process illustrated in FIG.

  In the determination process of step S716, when the determination is performed every time a predetermined time has elapsed, the number of times the determination process of step S716 has been performed exceeds the predetermined number of times, as illustrated in FIG. Processing may end in error.

[3-3. Application example]
Next, an application example in which abnormal banknotes are returned and conveyed intermittently in order to further suppress the scattering of abnormal banknotes in return conveyance will be described.

  In the application example, the conveyance control unit 651 causes the conveyance unit 107 to intermittently convey the banknote determined to be abnormal in the conveyance state by the conveyance state determination unit 601 to the storage unit 501. Here, when the conveyance speed of a banknote is low, the rotation speed of the drive motor which drives the conveyance part 107 may become unstable. When an abnormal banknote is discharged to the storage unit 501 in a state where the rotation speed of the drive motor is higher than the control value, the abnormal banknote can be scattered.

  On the other hand, according to the application example, since the abnormal banknote is intermittently transported in the return transport, it is driven from when the leading edge of the abnormal banknote is exposed to the outside from the housing unit 501 until the entire abnormal banknote is discharged. The operation of rotating and stopping the motor (conveying operation) is repeated a plurality of times. Therefore, the abnormal banknote is discharged to the storage unit 501 in a posture in which the tip is directed vertically downward according to gravity. Therefore, even if the rotational speed of the drive motor is higher than the control value, it is possible to suppress the scattering of abnormal banknotes that are discharged to the storage unit 501.

  The rotation continuation time of the drive motor per conveyance operation controlled by the conveyance control unit 651 is to prevent the abnormal banknotes from being scattered when the abnormal banknotes are discharged to the storage unit 501 in the return conveyance. It is set in consideration of the bill conveyance speed in the return conveyance.

  FIG. 13 is an explanatory diagram for explaining the detected portion 580 and the feed roller sensor 590 provided in the cash processing apparatus according to the application example. As shown in FIG. 13, a substantially fan-shaped detected portion 580 having an arc corresponding to a position where the high friction member 507a is provided is provided on the side surface of the feed roller 507 according to the application example. The detected portion 580 is a member having a gloss different from that of the side surface of the feed roller 507, for example. The detected portion 580 and the feed roller 507 rotate as a unit.

  Further, in the cash processing apparatus according to the application example, a feed roller sensor 590 disposed on the side of the feed roller 507 is provided. The feed roller sensor 590 is provided for detecting the posture of the feed roller 507. The feed roller sensor 590 has a detection surface (not shown) for detecting the gloss level of the opposing object. In FIG. 13, the detection surface (not shown) is a part of the outer peripheral side of the side surface of the feed roller 507. Are arranged opposite to each other. Since the feed roller sensor 590 is not fixed to the feed roller 507, the position of the feed roller sensor 590 does not depend on the rotation of the feed roller 507.

  For example, when the feed roller 507 is in the posture shown in FIG. 13, the detection surface (not shown) of the feed roller sensor 590 and the detected portion 580 are opposed to each other, so that the feed roller sensor 590 has the gloss level of the detected portion 580. Is detected. On the other hand, when the feed roller 507 rotates from the posture shown in FIG. 13 and the detection surface (not shown) of the feed roller sensor 590 faces the side surface of the feed roller 507, the feed roller sensor 590 The gloss level of the side surface 507 is detected.

  Hereinafter, the state where the detection surface (not shown) of the feed roller sensor 590 and the detected portion 580 face each other is referred to as the ON state of the feed roller sensor 590, and the detection surface (not shown) of the feed roller sensor 590 and the side surface of the feed roller 507. Is the OFF state of the feed roller sensor 590. The feed roller sensor 590 outputs information indicating whether the feed roller sensor 590 is in an ON state or an OFF state as a detection result.

  The conveyance control unit 651 stops the pickup roller 505 in a predetermined posture after the banknote whose conveyance state is determined to be abnormal by the conveyance state determination unit 601 is conveyed to the storage unit 501 by the conveyance unit 107. Specifically, after the abnormal banknote is transported to the storage unit 501, the transport control unit 651 switches each roller when the feed roller sensor 590 switches from the ON state to the OFF state and further switches from the OFF state to the ON state. Stop driving. Thereby, the feed roller 507 can be stopped in a predetermined posture. Here, the pickup roller 505 and the feed roller 507 are connected via a gear, a chain, a belt, or the like, and rotate in synchronization with each other, so that the pickup roller 505 can be stopped in a predetermined posture.

  The predetermined posture of the pickup roller 505 can be set to an arbitrary posture by changing the arrangement of the detected portion 580 or the feed roller sensor 590. For example, by setting the predetermined posture to be the posture of the pickup roller 505 at the time of resuming the deposit transaction, the posture of the pickup roller 505 for resuming the deposit transaction is adjusted after returning from the conveyance abnormality. It is possible to reduce labor.

  Hereinafter, the flow of the return process from the conveyance abnormality in the application example will be described. The flow of the return process from the conveyance abnormality in the application example is compared with the process shown in FIG. 12 from the process of returning the abnormal banknote (step S802) to the process of stopping the banknote conveyance in the return conveyance (step S722). The processing of is different. Hereinafter, the processing from step S802 to step S722 will be described.

  FIG. 14 is a flowchart illustrating an example of a flow of return processing from a conveyance abnormality in the application example. In the application example, in the return conveyance in which the conveyance unit 107 conveys the abnormal banknote to the accommodation unit 501, the conveyance control unit 651 causes the conveyance unit 107 to intermittently convey the abnormal banknote to the accommodation unit 501 (step S802).

  Then, the conveyance control unit 651 determines whether or not all of the first conveyance unit sensor 553, the second conveyance unit sensor 555, and the third conveyance unit sensor 557 are in the OFF state (step S804). Here, the determination of the determination process in step S804 may be performed constantly or every time a predetermined time elapses. The predetermined time is a value obtained by dividing the conveyance speed in the conveyance back to the length of the conveyance unit 107 from the high-speed conveyance roller 515 to the accommodation unit 501, and the abnormal banknote in the cash processing apparatus 1 is stored in the accommodation unit. This time is estimated to be sufficient as the time for being transported to 501. Thereby, the burden of the determination process of step S804 can be reduced. In the calculation of the predetermined time, the braking time of the drive motor that drives each roller of the transport unit 107 may be taken into consideration.

  When it is determined that any one or more of the transport unit sensors are in the ON state (step S804 / NO), the transport control unit 651 stops the banknote transport by the transport unit 107 (step S806). Next, the conveyance control unit 651 determines whether or not the operation of rotating and stopping the drive motor (conveying operation) repeated in the intermittent conveyance of banknotes has been repeated a predetermined number of times (step S808). If it is determined that the transport operation has not been repeated a predetermined number of times (step S808 / NO), the process returns to step S804 to determine the ON / OFF state of the transport unit sensor. On the other hand, when it is determined that the transport operation has been repeated a predetermined number of times (step S808 / YES), the process illustrated in FIG.

  In the determination process of step S804, the conveyance control unit 651 determines whether or not the feed roller sensor 590 is in the ON state when it is determined that all the conveyance unit sensors are in the OFF state (YES in step S804). Step S810). When it is determined that the feed roller sensor 590 is not in the ON state (step S810 / NO), the conveyance control unit 651 determines whether a predetermined time has elapsed (step S812). If the conveyance control unit 651 determines that the predetermined time has not elapsed (step S812 / NO), the process returns to step S810 to determine whether the feed roller sensor 590 is in the ON state. On the other hand, when it is determined by the conveyance control unit 651 that a predetermined time has elapsed (step S812 / YES), the process illustrated in FIG.

  If it is determined in step S810 that the feed roller sensor 590 is in the ON state (step S810 / YES), the conveyance control unit 651 determines whether the feed roller sensor 590 is in the OFF state (step S810). S814). If it is determined that the feed roller sensor 590 is not in the OFF state (step S814 / NO), the conveyance control unit 651 determines whether a predetermined time has elapsed (step S816). When the conveyance control unit 651 determines that the predetermined time has not elapsed (step S816 / NO), the process returns to the process of step S814 to determine whether or not the feed roller sensor 590 is in the OFF state. On the other hand, when it is determined by the conveyance control unit 651 that a predetermined time has elapsed (step S816 / YES), the process illustrated in FIG.

  If it is determined in step S814 that the feed roller sensor 590 is in the OFF state (step S814 / YES), the conveyance control unit 651 determines whether the feed roller sensor 590 is in the ON state (step S814). S818). When it is determined that the feed roller sensor 590 is not in the ON state (step S818 / NO), the conveyance control unit 651 determines whether a predetermined time has elapsed (step S820). If the conveyance control unit 651 determines that the predetermined time has not elapsed (step S820 / NO), the process returns to step S818 to determine whether the feed roller sensor 590 is in the ON state. On the other hand, when it is determined by the conveyance control unit 651 that a predetermined time has elapsed (step S820 / YES), the process illustrated in FIG.

  If it is determined that the feed roller sensor 590 is in the ON state in the determination process of step S818 (step S818 / YES), the conveyance control unit 651 stops the conveyance of banknotes by the conveyance unit 107 (step S722).

<4. Effect>
According to the above-described embodiment, when the conveyance control unit 651 acquires detection information indicating that no banknote is accommodated in the accommodation unit 501 after the conveyance of the banknote by the conveyance unit 107 is stopped by the stop control, The conveyance unit 107 causes the conveyance state determination unit 601 to convey the banknote determined to be abnormal in the conveyance state to the storage unit 501. Thereby, the abnormal banknote B2 in the cash processing apparatus 1 can be conveyed to the accommodating part 501 in the state in which the banknote bundle B1 is not accommodated in the accommodating part 501. Therefore, it can suppress that abnormal banknote B2 collides with bundle B1 of banknotes, and some banknotes B3 of bundle B1 of banknotes are scattered. Therefore, banknote management can be facilitated.

  According to an embodiment, the notification control unit 653 controls notification of predetermined information to the operator when the conveyance state determination unit 601 determines that the conveyance state is abnormal. Thereby, the removal of the banknotes stored in the storage unit 501 by the operator can be promoted before the abnormal banknotes are returned and conveyed. Therefore, it is possible to more reliably remove the banknote that can collide with the abnormal banknote transported from the cash processing apparatus 1 to the storage unit 501 in the return transport from the storage unit 501.

  Further, according to an application example, the transport control unit 651 causes the transport unit 107 to intermittently transport the banknotes determined to be abnormal by the transport state determination unit 601 to the storage unit 501. Here, when the conveyance speed of a banknote is low, the rotation speed of the drive motor which drives the conveyance part 107 may become unstable. When an abnormal banknote is discharged to the storage unit 501 in a state where the rotation speed of the drive motor is higher than the control value, the abnormal banknote can be scattered.

  On the other hand, according to the application example, since the abnormal banknote is intermittently transported in the return transport, it is driven from when the leading edge of the abnormal banknote is exposed to the outside from the housing unit 501 until the entire abnormal banknote is discharged. The operation of rotating and stopping the motor (conveying operation) is repeated a plurality of times. Therefore, the abnormal banknote is discharged to the storage unit 501 in a posture in which the tip is directed vertically downward according to gravity. Therefore, even if the rotational speed of the drive motor is higher than the control value, it is possible to suppress the scattering of abnormal banknotes that are discharged to the storage unit 501.

<5. Conclusion>
As described above, after the conveyance of the banknote by the conveyance unit is stopped by the stop control, when the detection information indicating that no banknote is accommodated in the accommodation unit is acquired, it is determined that the conveyance state is abnormal. Banknotes are transported to the storage unit. Thereby, the abnormal banknote in a cash processing apparatus can be conveyed to a accommodating part in the state in which the stack | stuck of the banknote is not accommodated in the accommodating part. Therefore, it can suppress that an abnormal banknote collides with the bundle | flux of a banknote, and a one part banknote of a bundle of banknotes is scattered. Therefore, banknote management can be facilitated.
