<Configuration of paper sheet processing device>
First, the configuration of the paper sheet processing device will be explained. FIG. 4 is a block diagram showing a schematic configuration of the paper sheet processing device.

The paper sheet processing apparatus 1 shown in FIG. , a storage state determination section 17 , and a control section 18 .

The first conveyance unit 11 conveys a rectangular paper sheet P in a first posture, which is one of a longitudinal conveyance posture and a transversal conveyance posture. The receiving section 12 receives paper sheets P from outside the paper sheet processing device 1 in a first attitude, and guides them to the first transport section 11 . The second conveyance unit 13 conveys the paper sheet P in a second posture, which is the other of the longitudinal conveyance posture and the transverse conveyance posture. In the first and second embodiments, a case will be explained in which the first posture is a short-side conveyance posture and the second posture is a longitudinal conveyance posture, but the first posture is a longitudinal conveyance posture. , the second posture may be a transversal conveyance posture.

The first storage section 14 stores the paper sheets P conveyed in the first posture by the first conveyance section 11 in the first posture. The first storage section 14 discharges the stored paper sheets P in a direction opposite to the storage direction without changing the orientation. The second storage section 15 stores the paper sheets P conveyed in the second posture by the second conveyance section 13 in the second posture. The second storage section 15 discharges the stored paper sheets P in a direction opposite to the storage direction without changing the orientation.

The first storage section 14 and the second storage section 15 may be constituted by a roll-up type storage unit in which a plurality of paper sheets P are stored in a state of being wound up on a rotary body, or a plurality of paper sheets P may be stored in a roll-up type storage unit. It may be constructed of a stacked storage unit in which the class P is stored in a stacked state. The storage methods (winding type or stacking type) of the first storage part 14 and the second storage part 15 may be the same or different. At least one of the first storage section 14 and the second storage section 15 may be configured to be detachable from the paper sheet processing device 1 . In the first and second embodiments, the first storage section 14 is a recycling storage section that stores recyclable paper sheets P, and the second storage section 15 is connected to other paper sheet processing devices such as a change machine. The case will be explained by exemplifying a case where the first storage section 14 is a removable storage section for moving paper sheets P between the two, but the first storage section 14 is a removable storage section and the second storage section 15 is a recycling storage section. It's okay.

The attitude change unit 16 is disposed between the first conveyance unit 11 and the second conveyance unit 13 and changes the paper sheet P conveyed by one of the first conveyance unit 11 and the second conveyance unit 13. , rotated by 90° in the first direction D1 (see FIG. 6B). The posture changing unit 16 rotates the paper sheet P around an axis perpendicular to the main surface of the paper sheet P. It is preferable that the posture changing unit 16 rotates the paper sheet P around an axis passing through the center of the paper sheet P.

The storage state determination unit 17 determines whether the storage state of the paper sheets P in the first storage unit 14 satisfies a predetermined criterion. The predetermined criterion is that the difference in thickness between the thickest part and the thinnest part of the storage body made up of the plurality of paper sheets P in the first storage part 14 is less than or equal to a threshold value, or , it can be exemplified that the number of paper sheets P stored in the first storage section 14 is less than or equal to the set number. Note that the storage body means a roll of paper sheets P when the first storage section 14 is a roll-up type, and means a roll of paper sheets P when the first storage section 14 is a stacked type. It means a bundle of leaves P.

The control unit 18 performs a first storage process or a second storage process when transporting the paper sheet P accepted by the receiving unit 12 to the first storage unit 14 based on the determination result in the storage state determination unit 17. The first transport section 11, the second transport section 13, the first storage section 14, the second storage section 15, and the attitude change section 16 are controlled in this manner. Details of the first storage process and the second storage process will be described later.

<Operation of paper sheet processing equipment>
Next, the operation of the paper sheet processing device 1 will be explained. The paper sheet processing device 1 of the first embodiment has two functions: "Storage processing of paper sheets P received by the receiving section 12 into the first storage section 14" and "processing of storing the paper sheets P in the second storage section 15". A process of storing sheets P in the first storage unit 14 and a process of storing paper sheets P in the first storage unit 14 in the second storage unit 15 can be performed. Hereinafter, "the process of storing paper sheets P received by the receiving unit 12 in the first storage unit 14" will be described in detail, and other processes will be briefly described. FIG. 5 is a flowchart showing the process of storing paper sheets accepted by the receiving unit into the first storage unit. FIG. 6A is an explanatory diagram of the first storage process. FIG. 6B is an explanatory diagram of the second storage process.

<Storage processing of paper sheets accepted by the receiving section into the first storage section>
As shown in FIG. 5, the receiving unit 12 receives a plurality of paper sheets P brought in by the user one by one in a first attitude (step S1). The control unit 18 controls the first transport unit 11 to transport the paper sheet P in the first attitude. On the other hand, the storage state determining unit 17 determines whether the storage state of the paper sheets P in the first storage unit 14 satisfies a predetermined criterion (step S2).

When the storage state determination unit 17 determines that the storage state of the first storage unit 14 satisfies the predetermined criteria (step S2: YES), the control unit 18 performs the first storage process (step S3). In the first storage process of step S3, the control unit 18 controls the first transport unit 11 and the first storage unit 14 to guide the guide from the receiving unit 12 to the first transport unit 11 as shown in FIG. 6A. The paper sheets P are stored in the first storage section 14 in the first orientation (first orientation) without passing through the orientation changing section 16 and the second storage section 15.

On the other hand, as shown in FIG. 5, when the storage state determining section 17 determines that the storage state of the first storage section 14 does not satisfy the predetermined standard (step S2: NO), the control section 18 controls the storage state of the first storage section 14 to Processing is performed (step S4). In the second storage process of step S4, the control unit 18 controls the first transport unit 11, the second transport unit 13, the first storage unit 14, the second storage unit 15, and the posture change unit 16, and 6B, the paper sheets P guided from the receiving section 12 to the first conveying section 11 are passed through the posture changing section 16, the second storage section 15, and the posture changing section 16, and are then By rotating it by 90 degrees in one direction D1, it is stored in the first storage part 14 in a second orientation (first attitude) different from the first orientation. Note that in the present disclosure, when the first direction is the direction of A pattern, B pattern, C pattern, D pattern, E pattern, F pattern, G pattern, or H pattern, the second direction is B pattern, The orientation is A pattern, D pattern, C pattern, F pattern, E pattern, H pattern, or G pattern.

As shown in FIG. 5, when the control unit 18 performs the first storage process in step S3 or the second storage process in step S4, the control unit 18 moves all paper sheets P accepted by the receiving unit 12 into the first storage process. It is determined whether or not it has been stored in the storage section 14 (step S5). When the control unit 18 determines that all the paper sheets P are not stored in the first storage unit 14 (step S5: NO), the control unit 18 executes the process of step S2. On the other hand, when the control unit 18 determines that all the paper sheets P have been stored in the first storage unit 14 (step S5: YES), the process ends.

Here, if the configuration is such that only the first storage process shown in FIG. 6A is performed without the storage state determination unit 17 determining whether the storage state of the first storage unit 14 satisfies a predetermined criterion, for example, When all the paper sheets P received by the receiving section 12 are oriented in the B pattern, all the paper sheets P are stored in the first storage section 14 in the B pattern direction (first direction). In this case, in the first storage section 14, since the thick parts Px of all the paper sheets P overlap, the difference in thickness between the thickest part and the thinnest part of the storage body, that is, the thick part Px of the storage body There is a possibility that the difference between the part where the thick part Px is included and the part where the thick part Px is not included becomes large.

In contrast, in the first embodiment, the control unit 18 performs the first storage process shown in FIG. 6A or the first storage process shown in FIG. Alternatively, the second storage process shown is performed. For this reason, for example, if all the paper sheets P accepted by the receiving section 12 are oriented in the B pattern, the paper sheets P conveyed in the first storage process will be oriented in the B pattern (the first direction ), but the paper sheets P conveyed by the second storage process are stored in the first storage part 14 in the A pattern orientation (second orientation). Therefore, it is possible to prevent the thick portions Px of all the paper sheets P from overlapping in the first storage section 14. Therefore, the paper sheet processing device 1 can suppress the difference in thickness between the thickest part and the thinnest part of the storage body from increasing, and properly store the paper sheets P in the first storage part 14. It can be stored.

<Storing process of paper sheets in the second storage section to the first storage section>
The second storage section 15 discharges the plurality of paper sheets P in the second storage section 15 one by one under the control of the control section 18 in the second attitude. The control section 18 controls the second conveyance section 13 and the posture change section 16 to convey the paper sheet P in the second posture and rotate it by 90 degrees in the first direction D1. Then, the control unit 18 controls the first conveyance unit 11 and the first storage unit 14 to store the paper sheet P, which has been converted from the second orientation to the first orientation, in the first storage unit 14 . The control unit 18 repeats the above-described process until all the paper sheets P discharged from the second storage unit 15 are stored in the first storage unit 14.

<Storing process of paper sheets in the first storage section to the second storage section>
The first storage section 14 discharges the plurality of paper sheets P in the first storage section 14 one by one in the second attitude based on the control of the control section 18 . The control unit 18 controls the first conveyance unit 11 and the posture changing unit 16 to convey the paper sheet P in the first posture and rotate it by 90° in the first direction D1. Then, the control unit 18 controls the second conveyance unit 13 and the second storage unit 15 to store the paper sheet P converted from the first attitude to the second attitude in the second storage unit 15. The control unit 18 repeats the above-described process until all the paper sheets P discharged from the first storage unit 14 are stored in the second storage unit 15.

(Step S11). The control unit 18A controls the second conveyance unit 13 to convey the paper sheet P in the second attitude. The storage state determining unit 17 determines whether the storage state of the paper sheets P in the first storage unit 14 satisfies a predetermined criterion (step S12). As the predetermined criteria, the same conditions as those exemplified in the first embodiment can be exemplified.

When the storage state determination unit 17 determines that the storage state of the first storage unit 14 satisfies the predetermined criteria (step S12: YES), the control unit 18A performs the first storage process (step S13). In the first storage process of step S13, the control unit 18A controls the first conveyance unit 11, the first storage unit 14, and the posture change unit 16A to move the second storage unit 15 to the second storage unit 15 as shown in FIG. 9A. The paper sheets P ejected from the paper sheets P are stored in the first storage section 14 in a first direction (first posture) rotated by 90 degrees in the first direction D1.

On the other hand, as shown in FIG. 8, when it is determined that the storage state of the first storage section 14 does not satisfy the predetermined criteria (step S12: NO), the control section 18A performs the second storage process (step S14). In the second storage process of step S14, the control unit 18A controls the first conveyance unit 11, the first storage unit 14, and the posture change unit 16A to move the second storage unit 15 to the second storage unit 15 as shown in FIG. 9B. The paper sheets P ejected from the paper sheets P are stored in the first storage section 14 in a second direction (first attitude) rotated by 90 degrees in a second direction D2 opposite to the first direction D1.

As shown in FIG. 8, when the first storage process in step S13 or the second storage process in step S14 is performed, the control unit 18A stores all paper sheets P discharged from the second storage unit 15. It is determined whether or not it has been stored in the first storage section 14 (step S15). When the control unit 18A determines that all the paper sheets P are not stored in the first storage unit 14 (step S15: NO), the control unit 18A executes the process of step S12. On the other hand, when the control unit 18A determines that all the paper sheets P have been stored in the first storage unit 14 (step S15: YES), the process ends.

Here, if the configuration is such that only the first storage process shown in FIG. 9A is performed without using the storage state determination unit 17 to determine whether the storage state of the first storage unit 14 satisfies a predetermined criterion, for example, When all the paper sheets P discharged from the second storage section 15 are oriented in the E pattern, all the paper sheets P are stored in the first storage section 14 in the A pattern direction (first orientation). Ru. In this case, in the first storage section 14, since the thick parts Px of all the paper sheets P overlap, the difference in thickness between the thickest part and the thinnest part of the storage body, that is, the thick part Px of the storage body There is a possibility that the difference between the part where the thick part Px is included and the part where the thick part Px is not included becomes large.

On the other hand, in the second embodiment, the control unit 18A performs the first storage process shown in FIG. 9A or the first storage process shown in FIG. Alternatively, the second storage process shown is performed. Therefore, for example, if all the paper sheets P discharged from the second storage section 15 are oriented in the E pattern, the paper sheets P conveyed by the first storage process are oriented in the A pattern (the The paper sheets P conveyed by the second storage process are stored in the first storage unit 14 in the B pattern orientation (second orientation). Therefore, it is possible to prevent the thick portions Px of all the paper sheets P from overlapping in the first storage section 14. Therefore, the paper sheet processing device 1A can suppress the difference in thickness between the thickest part and the thinnest part of the storage body from increasing, and properly store the paper sheets P in the first storage part 14. It can be stored.

It may be determined whether the Furthermore, the storage state determination section 30 may use the identification result of the identification section 214 instead of the counting result of the counter.

<Operation of paper sheet processing equipment>
Next, the operation of the paper sheet processing device 2 will be explained. The paper sheet processing device 2 of the third embodiment performs a process of storing paper sheets P deposited from the depositing unit 211 into the recycling storage unit 252, and recycling of paper sheets P in the paper sheet transport cassette 20. A process of storing paper sheets P in the recycle storage unit 252 into the paper sheet transport cassette 20 can be carried out. Hereinafter, the process of storing the paper sheets P deposited from the deposit unit 211 in the recycling storage unit 252 will be described in detail, and the other processes will be briefly described. 13 to 15 are flowcharts showing the process of storing paper sheets deposited from the deposit section into the recycling storage section.

<Paper sheets deposited from the deposit department are stored in the recycling storage department>
As shown in FIG. 13, the deposit unit 211 accepts a plurality of paper sheets P brought in by the user one by one in a transversal conveyance posture (step S21). The control unit 24 controls the first conveyance unit 28A to convey the paper sheets P on the second conveyance path 282 and the upper path 281A. The identification unit 214 performs a process of determining the authenticity of the paper sheets P on the upper path 281A, a process of identifying the denomination and fitness, and a process of detecting the orientation of the paper sheets P, and controls the results of these processes. 24.

The control unit 24 determines the storage location of the paper sheet P to be the recycling storage unit 252 or the collection unit 26 based on the denomination and fitness identification results sent from the identification unit 214. When the control unit 24 determines that the recycle storage unit 252 is the storage destination for the paper sheets P, the storage state determination unit 30 determines whether the thickest part and the thinnest part of the bundle of paper sheets P in the recycle storage unit 252 are determined to be the recycle storage unit 252. It is determined whether the difference in thickness is less than or equal to a threshold value (step S22).

When the storage state determination unit 30 determines that the difference in thickness between the thickest portion and the thinnest portion is equal to or less than the threshold (step S22: YES), the control unit 24 performs the first conveyance process (step S23). In the first conveyance process in step S23, the control section 24 controls the first conveyance section 28A and the recycling storage section 252 to convey the paper sheets P in the clockwise direction in FIG. 10 on the first conveyance path 281. , and store it in the recycling storage section 252. In the first storage process, for example, as shown in FIG. 11A, paper sheets P deposited from the deposit section 211 in the A pattern orientation are stored in the recycling storage section 252 in the A pattern orientation (first orientation). be done. Further, the control unit 24 calculates the number of paper sheets stored in each orientation in each recycling storage unit 252 based on the detection result of the orientation of the paper sheets P transmitted from the identification unit 214.

Next, the control unit 24 determines whether there is any paper sheet P being transported by the first transport unit 28A (step S24). The control unit 24 determines that there is no paper sheet P being transported by the first transport unit 28A (step S24: NO), that is, all the paper sheets P deposited from the depositing unit 211 are stored in the recycling storage unit 252 or the collection unit 26. If it is determined that it has been stored in , the process ends. On the other hand, the control unit 24 determines that there are paper sheets P being transported by the first transport unit 28A (step S24: YES), that is, all the paper sheets P deposited from the depositing unit 211 are sent to the recycling storage unit 252 or collected. If it is determined that it is not stored in the section 26, the process of step S22 is executed. In other words, the control unit 24 determines whether the difference in thickness between the thickest part and the thinnest part of the bundle of paper sheets P in the recycling storage section 252 in which the next paper sheet P is stored is less than or equal to the threshold value. Determine whether or not.

When the storage state determination unit 30 determines that the difference in thickness between the thickest part and the thinnest part exceeds the threshold (step S22: NO), the control unit 24 performs the second storage process (step S25). ). As shown in FIG. 14, in the second storage process of step S25, the control unit 24 controls the paper sheets P in the recycle storage section 252, which is determined as the storage destination of the paper sheets P to be stored next. The orientation during conveyance detected most frequently by the identification unit 214 is specified as the determination reference orientation (step S31).

The control unit 24 determines whether the orientation of the paper sheet P to be stored in short-side conveyance is in the determination reference orientation based on the identification result in the identification unit 214 (step S32). When the control unit 24 determines that the orientation of the paper sheet P to be stored is not the determination reference orientation (step S32: NO), the control unit 24 performs the same process as the first conveyance process in step S23, as shown in FIG. 11A. Then, the paper sheet P is stored in the recycling storage section 252 (step S33). On the other hand, when the control unit 24 determines that the orientation of the paper sheets P to be stored is in the determination reference orientation (step S32: YES), the control unit 24 controls the first transport unit 28A and the multipurpose storage unit 251 to Paper sheets P are transported clockwise on the transport path 281 and temporarily stored in the multipurpose storage section 251 as shown in FIG. 11B (step S34).

Here, in the processing of steps S33 and S34, the reason why the storage destination of the paper sheet P to be stored is changed depending on whether the orientation of the paper sheet P to be stored is the determination reference orientation will be explained. When storing paper sheets P in the recycling storage section 252, the paper sheets P deposited from the deposit section 211 in the A pattern orientation are detected by the identification section 214 as having the A pattern orientation. It is stored in the recycling storage section 252 in the orientation of pattern A. That is, the paper sheets P are stored in the recycling storage section 252 in the same orientation as the orientation detected by the identification section 214. Therefore, for example, when the determination reference orientation is the A-pattern orientation, when the paper sheet P detected by the identification unit 214 as having the A-pattern orientation is stored in the recycling storage unit 252, the paper sheet P The difference in thickness between the thickest part and the thinnest part of the bundle becomes even larger. On the other hand, when paper sheets P detected by the identification unit 214 as being oriented in pattern B, pattern C, or pattern D are stored in the recycling storage unit 252, the thickest part of the bundle of paper sheets P is The difference in thickness with the thinnest part becomes smaller. In this way, in order to prevent the difference in thickness between the thickest part and the thinnest part of the bundle of paper sheets P from becoming large, depending on whether the orientation of the paper sheets P to be stored is in the judgment reference direction or not, Change the storage location of the paper sheet P.

After the processing in step S33 or step S34, the control unit 24 determines whether there is any paper sheet P being transported by the first transport unit 28A (step S35). When the control unit 24 determines that there is a paper sheet P being transported by the first transport unit 28A (step S35: YES), the control unit 24 performs the process of step S32 for the next paper sheet P to be stored. On the other hand, when determining that there is no paper sheet P being transported by the first transport section 28A (step S35: NO), the control section 24 determines whether or not the paper sheet P is stored in the multipurpose storage section 251. A determination is made (step S36).

When the control unit 24 determines that the paper sheet P is not stored in the multipurpose storage unit 251 (step S36: NO), the process ends. On the other hand, when the control unit 24 determines that the paper sheets P are stored in the multipurpose storage unit 251 (step S36: YES), the control unit 24 controls the multipurpose storage unit 251 to store the paper sheets P in the multipurpose storage unit 251 as shown in FIG. The paper sheets P are discharged from the storage section 251 in a short-side conveyance posture (step S37). The control unit 24 controls the first conveyance unit 28A and the posture change unit 217 to convey the paper sheet P in the counterclockwise direction on the first conveyance path 281, and changes the posture as shown in FIG. 11B. 217 to rotate it by 90° in the first direction D1 (step S38). Further, the control unit 24 controls the second transport unit 28B and the paper sheet transport cassette 20 to temporarily store the paper sheet P rotated by the posture changing unit 217 in the paper sheet transport cassette 20. (Step S39).

The control unit 24 determines whether there is any paper sheet P being transported by the first transport unit 28A or the second transport unit 28B (step S40). When the control unit 24 determines that there is a paper sheet P being transported (step S40: YES), it performs the process of step S38 for the next paper sheet P to be stored. On the other hand, when the control unit 24 determines that there is no paper sheet P being transported (step S40: NO), the control unit 24 controls the paper sheet transport cassette 20 to remove the paper sheets P from the paper sheet transport cassette 20. It is discharged in a longitudinal conveyance position (step S41). The control unit 24 controls the second transport unit 28B and the attitude change unit 217 to cause the attitude change unit 217 to rotate by 90° in the first direction D1, as shown in FIG. 11B (Step S42). Further, the control unit 24 controls the first conveyance unit 28A and the recycling storage unit 252 to store the paper sheets P rotated by the posture changing unit 217 into the recycling storage unit 252 (step S43).

The control unit 24 determines whether there is any paper sheet P being transported by the second transport unit 28B (step S44). When the control unit 24 determines that there is a paper sheet P being transported (step S44: YES), the control unit 24 performs the process of step S42 for the next paper sheet P to be stored. On the other hand, when the control unit 24 determines that there is no paper sheet P being transported (step S44: NO), the control unit 24 ends the process.

As a result of the above processing, for example, when the reference determination orientation is the A pattern orientation, the paper sheet P deposited into the depositing unit 211 in the A pattern orientation is changed by the orientation changing unit 217 and is changed to the B pattern orientation. (second orientation) and is stored in the recycling storage section 252. On the other hand, the paper sheets P deposited into the deposit section 211 in the orientations of patterns B, C, and D are stored in the recycling storage section 252 in the same orientation (first orientation). For this reason, the paper sheet processing device 2 can suppress many thick portions Px from overlapping in the recycling storage section 252. Therefore, the paper sheet processing device 2 can suppress the difference in thickness between the thickest part and the thinnest part of the bundle of paper sheets (storage body) from increasing, and store the paper sheets in the recycling storage section 252. Leaves P can be appropriately stored.

In particular, in order to determine whether or not to directly store the paper sheet P in the recycling storage section 252 according to the orientation detected by the identification section 214, the orientation when the paper sheet P is received in the deposit section 211 is determined. Paper sheets P can be appropriately stored in the recycling storage section 252 regardless of the situation.

When performing the second storage process, the control unit 24 temporarily stores paper sheets P that are oriented toward the determination standard in the multipurpose storage section 251, while storing paper sheets P that is not oriented toward the determination standard in the recycling storage section 252. Store it. After all the paper sheets P deposited from the deposit section 211 are stored in the multipurpose storage section 251 or the recycling storage section 252, the control section 24 controls the paper sheets P stored in the multipurpose storage section 251. , the paper sheet transport cassette 20 , and the posture change section 217 , and are stored in the recycling storage section 252 . Therefore, instead of temporarily storing paper sheets P in the judgment reference orientation in the multi-purpose storage section 251, the paper sheets P are passed through the posture change section 217, the paper sheet transport cassette 20, and the posture change section 217, and then recycled and stored. Compared to the configuration in which the storage device is stored in the storage section 252, the implementation period of the second storage process can be shortened.

<Storage of paper sheets in the paper sheet transport cassette to the recycling storage section>
The process of storing the paper sheets P in the paper sheet transport cassette 20 into the recycling storage section 252 is performed, for example, as a sales revenue collection process. The paper sheet transport cassette 20 discharges the plurality of paper sheets P in the paper sheet transport cassette 20 one by one in a longitudinal transport posture. The control section 24 causes the posture change section 217 to rotate the paper sheet P in the longitudinal conveyance posture by 90 degrees in the first direction D1. Then, the control unit 24 stores the paper sheet P, which has been changed from the longitudinal transport orientation to the lateral transport orientation, in the recycling storage unit 252. The control unit 24 repeats the above-described process until all the paper sheets P discharged from the paper sheet transport cassette 20 are stored in the recycling storage section 252.

<Storage of paper sheets in the recycling storage section into the paper sheet transport cassette>
The process of storing the paper sheets P in the recycling storage section 252 into the paper sheet transport cassette 20 is performed, for example, as a process of replenishing change reserves for a change machine. The recycle storage unit 252 discharges the plurality of paper sheets P in the recycle storage unit 252 one by one in a transversal conveyance posture. The control section 24 causes the posture change section 217 to rotate the paper sheet P in the transversal conveyance posture by 90 degrees in the first direction D1. Then, the control unit 24 stores the paper sheet P, which has been converted from the transversal transport posture to the longitudinal transport posture, in the paper sheet transport cassette 20. The control unit 24 repeats the above-described process until all the paper sheets P discharged from the recycling storage section 252 are stored in the paper sheet transport cassette 20.

<Fourth embodiment>
Next, a fourth embodiment of the present disclosure will be described. The fourth embodiment is the same as the third embodiment in that it uses the paper sheet processing device 2 of the third embodiment, so the explanation will focus on the differences.

<Configuration of paper sheet processing device>
In the paper sheet processing device 2A of the fourth embodiment shown in FIGS. 10 and 12, the processing performed by the control unit 24A and the storage state determination unit 30A is the same as that of the control unit 24 and the storage state determination unit 30A of the third embodiment. This is different from the process carried out by .

The storage state determination unit 30A determines whether the storage state of paper sheets P in each recycling storage unit 252 satisfies a predetermined standard. In the fourth embodiment, the predetermined criterion is that the number of paper sheets P stored in each recycling storage section 252 is equal to or less than the set number. The set number of sheets may be set based on an input operation from an operation unit (not shown) of the sheet processing device 2A, and in this case, only a user authenticated by an authentication device may be allowed to set the set number of sheets. Further, the set number of sheets may be different for each denomination, or may be different for each transaction performed by the paper sheet processing device 2A. The storage state determination unit 30A includes, for example, a counter that counts the number of paper sheets P stored in each recycling storage unit 252, and a memory that stores the set number of sheets. The storage state determination unit 30A may use the identification result of the identification unit 214 instead of the counting result of the counter.

<Operation of paper sheet processing equipment>
Next, as an operation of the paper sheet processing device 2A, a process of storing paper sheets P deposited from the deposit section 211 into the recycling storage section 252 will be described with reference to FIGS. 15 to 17. 16 and 17 are flowcharts showing the process of storing paper sheets deposited from the deposit section into the recycling storage section. In addition, below, the case where all the paper sheets P accepted by the deposit part 211 are the same direction is demonstrated. Further, the description of the same processing as in the third embodiment will be simplified.

The identification unit 214 transmits to the control unit 24A a process for determining the authenticity of the paper sheets P conveyed on the upper path 281A, a process for identifying the denomination and fitness, and a process for detecting the orientation of the paper sheets P. do. When the storage destination of the paper sheets P is determined to be the recycling storage section 252 by the control section 24A, the storage state determination section 30A determines whether the number of sheets P stored in the recycling storage section 252 is less than or equal to the set number. It is determined whether or not (step S51).

When the storage state determination unit 30A determines that the number of sheets stored is equal to or less than the set number (step S51: YES), the control unit 24A performs the first conveyance process (step S23). Next, the control unit 24A determines whether there is any paper sheet P being transported by the first transport unit 28A (step S24). When the control unit 24A determines that there is no paper sheet P being transported by the first transport unit 28A (step S24: NO), the process ends. On the other hand, when the control unit 24A determines that there is a paper sheet P being transported by the first transport unit 28A (step S24: YES), the control unit 24A executes the process of step S51. That is, the control unit 24A determines whether or not the number of paper sheets P stored in the recycling storage section 252 in which the next paper sheet P is stored is equal to or less than the set number of sheets, through the process of step S23.

When the storage state determination unit 30A determines that the number of sheets stored in the recycle storage section 252 exceeds the set number (step S51: NO), the control section 24 performs the second storage process (step S52). As shown in FIG. 17, in the second storage process of step S52, the control unit 24A temporarily stores the next paper sheet P to be stored in the multipurpose storage unit 251 (step S34). After the process of step S34, the control unit 24A determines whether there is any paper sheet P being transported by the first transport unit 28A (step S35). When the control unit 24A determines that there is a paper sheet P being transported by the first transport unit 28A (step S35: YES), the control unit 24A performs the process of step S34 for the next paper sheet P to be stored. On the other hand, when the control unit 24A determines that there is no paper sheet P being transported by the first transport unit 28A (step S35: NO), the control unit 24A performs steps S37 to S44 shown in FIG. 15 similarly to the third embodiment. Processing will be carried out.

As a result of the above processing, for example, if all the paper sheets P are deposited into the deposit section 211 in the A-pattern orientation, until the number of sheets stored in the recycling storage section 252 reaches the set number, the A-pattern orientation (the After the number of sheets stored reaches the set number, the orientation is changed by the orientation changing section 217 and the sheets are stored in the recycling storage section 252 in the B pattern orientation (second orientation). be done. For this reason, the paper sheet processing device 2A can suppress many thick portions Px from overlapping in the recycling storage section 252. Therefore, the paper sheet processing device 2A can suppress the difference in thickness between the thickest part and the thinnest part of the bundle of paper sheets (storage body) from increasing, and store the paper sheets in the recycling storage section 252. Leaves P can be appropriately stored.
