It is stored in the first to sixth storage cassettes 261 to 266 according to the type. At this time, the bill P is stored in the first to sixth storage cassettes 261 to 266 in a short transport posture.

The control unit 31 controls the transport unit 5 and the fourth to ninth branching mechanisms 554 to 559 based on the identification result to deliver the non-depositable banknote P in a short transport posture to the withdrawal unit 24. To be transported to.

The control unit 31 holds the depositable banknotes P in the temporary holding unit 30, and after the processing of all the banknotes P inserted in the depositing unit 21 is completed, the banknotes P in the temporary holding unit 30 are first to 1st. It may be controlled to be stored in the sixth storage cassettes 261 to 266. For example, the control unit 31 controls the transport unit 5, the sixth to ninth branching mechanisms 556 to 559, and the temporary holding unit 30, and holds the depositable banknote P in the temporary holding unit 30. The control unit 31 controls the transport unit 5 and the fourth to ninth branching mechanisms 554 to 559 to transport the non-depositable banknote P to the withdrawal unit 24. After the processing of all the banknotes P inserted into the deposit unit 21 is completed, the control unit 31 includes the temporary holding unit 30, the transport unit 5, the identification unit 25, and the fourth, sixth to twelfth branching mechanisms 554,556. ~ 562 and the first to sixth storage cassettes 261 to 266 are controlled, and the depositable banknotes P temporarily held in the temporary holding unit 30 are classified into the first to sixth storage cassettes 261 to 266. You may store it in.

[Withdrawal processing to the withdrawal department]
Next, the withdrawal process to the withdrawal unit 24 will be described. In the withdrawal process to the withdrawal unit 24, the paper leaf processing device 1 pulls out the bills P from the first to sixth storage cassettes 261 to 266 in the short transport posture in the short transport posture. , Withdraw from the withdrawal section 24.

The operator performs an operation to start a withdrawal process for a predetermined number of banknotes P of a predetermined denomination. The control unit 31 controls the first to sixth storage cassettes 261 to 266, the transport units 5, and the seventh to twelfth branch mechanisms 557 to 562, and transports the bills P one by one to the identification unit 25. At this time, the bill P is transported to the identification unit 25 in a short transport posture. The identification unit 25 identifies the bills P to be sequentially transported, generates a signal indicating the identification result, and outputs the signal to the control unit 31. The control unit 31 determines whether the banknote P can be withdrawn or the banknote P cannot be withdrawn based on the received signal.

The control unit 31 controls the transport unit 5 and the first, second, fourth, and fifth branching mechanisms 551,552,554,555 based on the identification result, and shortens the withdrawable banknote P. It is transported to the withdrawal unit 24 in a manual transport posture.

The control unit 31 controls the transport unit 5, the first, second, fourth, and sixth branch mechanisms 551,552,554,556 and the temporary holding unit 30 based on the identification result, and cannot withdraw money. The bill P is held in the temporary holding section 30 in a short-handed posture. After all the banknotes P to be withdrawn have been conveyed to the withdrawal unit 24, the control unit 31 has the temporary holding unit 30 and the second, third, sixth to ninth branching mechanisms 552, 535, 556 to 559. Is controlled to convey the non-depositable banknote P to the upper reject storage unit 28. At this time, the posture change unit 6 does not change the posture of the bill P. Therefore, the bill P is transported to the upper reject storage unit 28 in a short transport posture.

[Payment processing from banknote transport cassette]
Next, the deposit processing from the bill transport cassette 15 will be described. In the deposit processing from the bill transport cassette 15, the control unit 31 changes the posture of the bill P by rotating the bill P longitudinally transported from the bill transport cassette 15, and in the short transport posture, the first -Store in the sixth storage cassettes 261 to 266. FIG. 5 is a timing chart showing control during the rotation processing of banknotes. FIG. 6 is an explanatory diagram of a detection process of the posture of the banknotes to be vertically transported, the length in the direction of the banknotes transport path, and the position in the width direction of the banknote transport path. 7A, 7B, 7C, 7D and 7E are schematic views showing control during rotation processing of banknotes. FIG. 8 is an explanatory diagram of a detection process of a posture of a bill to be transported by hand, a length in the direction of the bill transport path, and a position in the width direction of the bill transport path.

The operator mounts the banknote transport cassette 15 on the cassette mounting unit 22, and uses the operation unit to start the deposit processing. The control unit 31 controls the banknote transport cassette 15, the deposit / withdrawal section 23, the transport section 5, and the third branching mechanism 553 to transport the banknotes P one by one to the posture change unit 6. At this time, the bill P is unwound from the bill transport cassette 15 in the posture of longitudinal transport, and is conveyed to the posture change unit 6 in that posture.

As shown in FIG. 5, the control unit 31 sets the set rotation speeds of the first and second direction changing rollers 611 and 612 in a state where the third contact roller 616 is in the ascending position and the upper roller 63 is in the descending position. Is set to S1, the set rotation speed of the third direction changing roller 613 is set to 0, and the set rotation speed of the lower roller 62 is set to be the same as, for example, the first and second direction changing rollers 611 and 612, so that the first and second directions are changed. By driving the direction changing rollers 611 and 612 and the lower roller 62, the bill P is conveyed from the back to the front of the paper leaf processing device 1 in a longitudinal transport posture. At this time, the bill P is conveyed while being in contact with the first to third direction changing rollers 611 to 613, the first and second contact rollers 614, 615, the lower roller 62, and the upper roller 63. The third direction changing roller 613 is driven to rotate as it comes into contact with the bill P.

As shown in FIG. 6, the rear detection unit 65 of the posture change unit 6 has a posture of the bill P to be transported, a length L of the direction Dt of the transport path of the bill P, and a position of the width direction Dw of the transport path of the bill P. Is detected. The rear detection unit 65 detects the inclination angle α1 of the short side Pb with respect to the width direction Dw of the transport path as the posture of the bill P. That is, the rear detection unit 65 detects the inclination angle α1 of the side located in front of or behind the bill P. The rear detection unit 65 sets the position of the banknote P transport path in the width direction Dw from the shortest distance Mh from the left side wall 513A of the third transport path 513 to the bill P and the right side wall 513B of the third transport path 513. The shortest distance Mm to the bill P is detected. The rear detection unit 65 may detect the deviation between the center of the width direction Dw of the transport path and the center of the bill P in the transport path as the position of the width direction Dw of the transport path of the bill P. The rear detection unit 65 generates a signal indicating the detection result and outputs the signal to the control unit 31.

The control unit 31 determines whether or not to rotate the bill P based on the detection result of the rear detection unit 65. As a method for determining whether or not to rotate the bill P, at least one of the following first to third determination methods can be used.

In the first determination method, the control unit 31 obtains the distance (shortest distance) between the two bills P to be continuously conveyed based on the detection result in the rear detection unit 65, and the obtained distance is less than the threshold value. In this case, it is determined that the two bills P are not rotated. When the interval between the two banknotes P is less than the threshold value, the reason why the two banknotes P are not rotated is that the two banknotes overlap or the interval becomes too narrow when the two banknotes P are rotated. This is because there is a possibility that the transport and the identification in the identification unit 25 cannot be performed properly. After that, the control unit 31 determines whether or not to rotate the two banknotes P based on the distance between the two banknotes P that are conveyed following the two banknotes P that are determined not to be rotated.

On the other hand, when the obtained interval is equal to or greater than the threshold value, the control unit 31 determines that the bill P in front of the deposit transport direction is rotated among the two bills P, and then the bill P behind in the deposit transport direction and the bill. It is determined whether or not to rotate the two banknotes P based on the distance between the banknote P and the banknote P transported following the P.

In the second determination method, the control unit 31 obtains the distance between two bills P that are continuously conveyed based on the detection result of the rear detection unit 65. The control unit 31 assumes that the two banknotes P have been rotated based on the obtained interval and the position of the two banknotes P in the width direction Dw of the transport path, and these predicted intervals. Ask for. When the obtained prediction interval is less than the threshold value, the control unit 31 determines that the two bills P are not rotated. After that, the control unit 31 determines whether or not to rotate the two banknotes P based on the predicted interval of the two banknotes P to be conveyed following the two banknotes P determined not to be rotated. ..

On the other hand, when the obtained prediction interval is equal to or greater than the threshold value, the control unit 31 determines that the banknote P in front of the deposit transport direction is rotated among the two banknotes P, and then the banknote P behind in the deposit transport direction and the banknote P. It is determined whether or not to rotate the two bills P based on the predicted interval between the bill P to be conveyed following the bill.

In the third determination method, the method of obtaining the prediction interval is different from the method of the second determination method, but the method of determining the necessity of rotation using the prediction interval is the same as the second determination method. In the third determination method, the control unit 31 determines the distance between the two bills P that are continuously transported, the position of the two bills P in the width direction Dw of the transport path, and the two bills P. Prediction interval is calculated based on the size of. The size of the bill P can be determined, for example, based on the detection result in the rear detection unit 65.

The control unit 31 controls the posture change unit 6 based on the determination result of whether or not to rotate the bill P and the detection result of the rear detection unit 65.

When the control unit 31 determines that the banknote P is not rotated, the control unit 31 controls the transport unit 5, the second branch mechanism 552, and the identification unit 25 so that the posture change unit 6 does not rotate the banknote P and the identification unit 31. The bill P is transported without processing the bill P in 25, and the following first reject transport control or second reject transport control is performed.

In the first reject transfer control, the control unit 31 controls the transfer unit 5, the second, sixth to ninth branch mechanisms 552, 556 to 559, and the temporary holding unit 30, and the banknotes that have passed through the identification unit 25. P is held in the temporary holding unit 30. After the processing of all the banknotes P to be deposited is completed, the control unit 31 includes the temporary holding unit 30, the transport unit 5, the identification unit 25, the posture change unit 6, and the second, third, sixth to ninth branches. By controlling the mechanisms 552, 533, 556 to 559, the bill P is fed out from the temporary holding unit 30, and the identification processing and the rotation processing of the drawn bill P are not performed by the identification unit 25 and the posture changing unit 6, respectively. It is stored in the upper reject storage unit 28.

In the second reject transfer control, the control unit 31 controls the transfer unit 5 and the fourth to ninth branching mechanisms 554 to 559 to store the bill P that has passed through the identification unit 25 in the counting reject storage unit 29. ..

When the control unit 31 determines that the bill P is rotated, the control unit 31 controls the posture change unit 6 as follows based on the detection result of the rear detection unit 65. When the control unit 31 determines that the bill P has reached the rotation start position based on the detection result of the rear passage sensor 67, for example, the control unit 31 controls the posture change unit 6 to rotate the bill P. As shown in FIG. 5, the control unit 31 starts to slow down the set rotation speed of the first direction changing roller 611 from the time T1 when the rotation starts, and maintains the set rotation speed at S2 slower than S1 between the time T2 and the time T3. Then, it starts to speed up from time T3 and returns to S1 at time T4. The control unit 31 maintains the set rotation speed of the second direction changing roller 612 at S1 during the time T1 to T4. Between time T1 and time T4, the first direction-changing roller 611 rotates slower than the second direction-changing roller 612. Due to the difference in rotational speed between the first direction-changing roller 611 and the second direction-changing roller 612, the banknote P has the left edge facing backward and the right edge facing backward, as shown by the alternate long and short dash line in FIG. Rotate to face forward. That is, the bill P is rotated so that the end of the fast-rotating second direction-changing roller 612 faces forward and the end of the slow-rotating first direction-changing roller 611 faces backward.

From time T1, the control unit 31 starts rotating the third direction changing roller 613 in the direction opposite to that of the first and second direction changing rollers 611 and 612. That is, the control unit 31 starts rotating the third direction changing roller 613 so as to carry the bill P behind. The control unit 31 maintains the set rotation speed of the third direction changing roller 613 at S3 between the time T2 and the time T3, starts to slow down from the time T3, and returns the set rotation speed to 0 at the time T4. The magnitude of the set rotation speed S3 between the time T2 and the time T3 is not particularly limited, but is preferably equal to the difference between S1 and S2.

The control unit 31 brings the third contact roller 616 into contact with the bill P by lowering it between the time T1 and the time T4. By this contact, the rotational force of the third direction changing roller 613 is easily transmitted to the bill P.

The control unit 31 raises the third contact roller 616 at time T4 to separate it from the bill P. Due to this separation, the bill P can be smoothly conveyed.

The control unit 31 raises the upper roller 63 from the time T1 to the time T4 to separate it from the bill P. Due to this separation, the bill P can be smoothly rotated. Further, the lower roller 62 is provided with inclined surfaces 622A at both ends in the axial direction, and the lower roller 62 is arranged so that the upper end 622B is located below the upper surface of the third transport path 513. Therefore, the rotating bill P comes into contact with the inclined surface 622A of the lower roller 62 and moves along the inclined surface 622A. As a result, the bill P can be smoothly rotated.

At time T4, the control unit 31 lowers the upper roller 63 to bring it into contact with the bill P. By this contact, it is possible to prevent the bill P from rotating too much due to the inertia of rotation.

After the time T4 when the rotation ends, the bill P is forwardly conveyed by the first and second direction changing rollers 611 and 612 and the lower roller 62.

The control unit 31 determines the posture of the banknote P detected by the rear detection unit 65, the length L of the direction Dt of the banknote P transport path, and the width direction Dw of the banknote P transport path in the above-mentioned rotation process of the banknote P. Regardless of the position, the short side Pb of the rotated bill P is parallel to the direction Dt of the transport path, that is, the bill P is in the short transport posture, and the bill P is located at the center of the width direction Dw of the transport path. The attitude change unit 6 is controlled so as to do so. In the following, "a state in which the bill P is in the short transport posture and the bill P is located at the center of the width direction Dw of the transport path (the center of the short side Pb of the bill P)" is described as "payment." Sometimes called "target state".

For example, as shown by the alternate long and short dash line in the right side of FIG. 7A, the banknote P1 before rotation is located at the center of the width direction Dw of the transport path, and the inclination angle α1 of the short side Pb1 is 0 °. In this case, the control unit 31 determines the locus of the contact position between the first and second direction changing rollers 611 and 612 and the bill P1 (hereinafter, "contact between the first and second direction changing rollers 611 and 612 and the bill P". The "position locus" is sometimes referred to as the "contact locus"). By rotating the bill P1 as shown by the alternate long and short dash line in the center figure, the rotated bill is shown by the solid line in the left figure. Set P1 to the deposit target state. The reference numerals C in FIGS. 7A and 7B, 7C, 7D, and 7E, which will be described later, represent a line passing through the center of the width direction Dw of the transport path and parallel to the direction Dt of the transport path.

As shown by the solid line in the figure on the right side of FIG. 7A, the size of the banknote P2 is the same as that of the banknote P1, and the center of the banknote P2 before rotation is located on the left side of the center of the width direction Dw of the transport path. When the inclination angle α1 of the short side Pb2 is 0 °, the control unit 31 rotates the bill P2 so as to have a contact locus K2 as shown by the solid line in the central figure, so that the solid line is shown in the left figure. As shown by, the rotated banknote P2 is set to the deposit target state.

As shown in FIG. 7A, when the sizes are the same, the inclination angle α1 of the short side Pb is 0 °, and only the position of the width direction Dw of the transport path is different, the control unit 31 is set to the first and first positions. By making the control of the direction changing rollers 611 and 612 of No. 2 the same for the banknote P1 and the banknote P2, the banknotes P1 and P2 can be set to the deposit target state.

Next, another case will be described with reference to FIG. 7B. The three upper figures of FIG. 7B show the rotation control of the banknote P1 of FIG. 7A. As shown by a solid line in the lower right side of FIG. 7B, the length L3 of the long side Pa3 of the bill P3 is shorter than the length L1 of the long side Pa1 of the bill P1, and the bill P3 before rotation is the width of the transport path. When it is located in the center of the direction Dw and the inclination angle α1 of the short side Pb3 is 0 °, the control unit 31 has a contact locus K3 as shown by a solid line in the lower center figure. By rotating the banknote P3, as shown by the solid line in the lower left figure, the rotated banknote P3 is set to the deposit target state.

As shown in FIG. 7B, in the control unit 31, the bill P3 is in the direction Dt of the transport path after the first and second direction changing rollers 611 and 612 come into contact with the bill P3 and before the bill P3 starts to rotate. (Hereinafter, the distance that the bill P moves in the direction Dt of the transport path after the first and second direction conversion rollers 611 and 612 come into contact with the bill P and before the bill P starts to rotate. The first and second direction changing rollers 611 and 612 are controlled so that H3 is shorter than the linear transport distance H1 of the bill P1. That is, when the length L of the direction Dt of the transport path of the bill P is different and the inclination angle α1 of the short side Pb is 0 °, the control unit 31 makes the linear transport distance different according to the length L. Allows the banknote P to be in the deposit target state. Even if the banknote P3 before rotation is not located at the center of the width direction Dw of the transport path, the control unit 31 performs the same control as the lower center figure of FIG. 7B to perform the same control as the banknote after rotation. P3 can be set to the deposit target state.

Next, another case will be described with reference to FIG. 7C. The alternate long and short dash line in FIG. 7C shows the rotation control of the bill P1 in FIG. 7A. As shown by the solid line in the figure on the right side of FIG. 7C, the size of the banknote P4 is the same as that of the banknote P1, the center of the banknote P4 before rotation is deviated from the center of the width direction Dw of the transport path, and the state of the banknote P1. On the other hand, when the unit 6 is rotating in the direction opposite to the rotation direction, the inclination angle α1 of the short side Pb4 exceeds 0 °, and the length L4 of the direction Dt of the transport path of the bill P4 is the bill P1. The length of the direction Dt of the transport path is longer than L1. In this case, the control unit 31 rotates the bill P4 so that the contact locus K4 is as shown by the solid line in the center figure, and then deposits the rotated bill P4 as shown by the solid line in the left figure. Set to the target state.

As shown in FIG. 7C, the control unit 31 makes the linear transport distance H4 longer than the linear transport distance H1 of the bill P1 and makes the rotation angle of the bill P4 larger than the rotation angle of the bill P1. In addition, the first and second direction changing rollers 611 and 612 are controlled. That is, when the length L of the direction Dt of the transport path of the bill P is different and the bill P is rotated in the direction opposite to the rotation direction of the posture changing unit 6 with respect to the state of the bill P1, the control unit 31 transports the bill P in a straight line. By making the distance different according to the length L and increasing the rotation angle according to the inclination angle α1 before rotation, the bill P can be set to the deposit target state. The rotation angle can be adjusted by adjusting the length from the rotation start time T1 to the end time T4 and the speed difference between the first and second direction changing rollers 611 and 612. Even if the banknote P4 before rotation is deviated from the position shown in FIG. 7C in the width direction Dw of the transport path, the control unit 31 performs the same control as in the central figure of FIG. The bill P4 can be set to the deposit target state.

Next, another case will be described with reference to FIG. 7D. The alternate long and short dash line in FIG. 7D shows the rotation control of the bill P1 in FIG. 7A. As shown by the solid line in the figure on the right side of FIG. 7D, the size of the banknote P5 is the same as that of the banknote P1, the center of the banknote P5 before rotation is deviated from the center of the width direction Dw of the transport path, and the state of the banknote P1. On the other hand, when the unit 6 is rotating in the same direction as the rotation direction, the inclination angle α1 of the short side Pb5 exceeds 0 °, and the length L5 of the direction Dt of the transport path of the bill P5 is the bill P1. The length of the direction Dt of the transport path is longer than L1. In this case, the control unit 31 rotates the bill P5 so that the contact locus K5 is as shown by the solid line in the center figure, and then deposits the rotated bill P5 as shown by the solid line in the left figure. Set to the target state.

As shown in FIG. 7D, the control unit 31 makes the linear transport distance H5 longer than the linear transport distance H1 of the bill P1 and makes the rotation angle of the bill P5 smaller than the rotation angle of the bill P1. In addition, the first and second direction changing rollers 611 and 612 are controlled. That is, when the length L of the direction Dt of the transport path of the bill P is different and the bill P is rotated in the same direction as the rotation direction of the posture changing unit 6 with respect to the state of the bill P1, the control unit 31 transports the bill P in a straight line. By making the distance different according to the length L and reducing the rotation angle according to the inclination angle α1 before rotation, the bill P can be set to the deposit target state.

Next, based on FIG. 7E, the short side Pb of the rotated bill P is parallel to the direction Dt of the transport path, and the bill P is positioned at a position shifted to the left and right from the center of the width direction Dw of the transport path. A method of controlling the posture changing unit 6 will be described. The alternate long and short dash line in FIG. 7E shows the rotation control of the bill P1 in FIG. 7A. As shown by the solid line in the figure on the right side of FIG. 7E, the control unit 31 has the same size as the banknote P1 and the posture before rotation of the banknote P6 is the same as that of the banknote P1 and also has a position of Dw in the width direction of the transport path. In the same case, by rotating the banknote P6 so that the contact locus K6 is as shown by the solid line in the center figure, the rotated banknote P6 is moved to the left side from the deposit target state as shown by the solid line in the left figure. Put it in a misaligned state. That is, the control unit 31 rotates the bill P6 so that the linear transport distance H6 of the bill P6 is longer than the linear transport distance H1 of the bill P1.

As shown in FIG. 7E, the control unit 31 controls the first and second direction changing rollers 611 and 612 so that the linear transport distance H6 is longer than the linear transport distance H1 of the bill P1. That is, when the length L of the direction Dt of the banknote P transport path is the same, the control unit 31 adjusts the position of the banknote P transport path in the width direction Dw after rotation by adjusting the linear transport distance H. be able to.

As shown in FIGS. 7A to 7E, the control unit 31 rotates the bill P by 90 ± 20 ° to change from a longitudinal transport posture to a short transport posture, or as will be described later, a short transport posture. It is configured so that the posture of the bill P can be changed from the posture to the posture of the longitudinal transport.

When the rotation process of the bill P is completed, the control unit 31 determines whether or not the posture of the bill P is in the deposit target state, that is, the bill P is in the short transport posture and the bill P is in the transport path. It is determined whether or not the state is located at the center of the width direction Dw. For this determination, the detection result of the bill P by the front detection unit 64 or the identification unit 25 can be used.

For example, as shown in FIG. 8, the front detection unit 64 detects the posture of the banknote P after rotation and the position of the banknote P in the width direction Dw of the transport path. The front detection unit 64 detects the inclination angle α2 of the long side Pa with respect to the width direction Dw of the transport path as the posture of the bill P. That is, the front detection unit 64 detects the inclination angle α2 of the side located in front of or behind the bill P. The front detection unit 64 sets the position of the width direction Dw of the bill P transport path as the shortest distance Mh from the left side wall 513A of the third transport path 513 to the bill P and the shortest distance Mm from the right side wall 513B to the bill P. And detect. The front detection unit 64 may detect the deviation between the center of the width direction Dw of the transport path and the center of the bill P in the transport path as the position of the width direction Dw of the transport path of the bill P. Further, the identification unit 25 may also detect the posture of the banknote P after rotation and the position of the banknote P in the width direction Dw of the transport path by the same processing as the front detection unit 64.

The control unit 31 determines whether or not the inclination angle α2 is an angle at which the bill P can be regarded as a short-handed posture, that is, whether or not the deviation of the inclination angle α2 from 0 ° is less than the allowable angle. The control unit 31 determines whether or not the position of the width direction Dw of the bill P transport path can be regarded as the center position of the width direction Dw of the transport path, that is, from the center of the width direction Dw of the bill P transport path. It is determined whether or not the deviation is less than the allowable deviation amount.

When the deviation of the inclination angle α2 from 0 ° is less than the permissible angle and the deviation from the center of the width direction Dw of the transport path of the bill P is less than the permissible deviation amount, the control unit 31 deposits the bill P. Judge that the target state is reached. When the deviation of the inclination angle α2 from 0 ° is equal to or greater than the permissible angle, or the deviation of the inclination angle α2 from the center of the width direction Dw of the bill P is equal to or greater than the permissible deviation amount, the control unit 31 is in the deposit target state. It is judged that it is not.

When the control unit 31 determines that the rotated banknote P is not in the deposit target state, the control unit 31 performs the above-mentioned first reject transfer control or second reject transfer control.

When the control unit 31 determines that the rotated banknote P is in the deposit target state, the control unit 31 causes the identification unit 25 to identify the banknote P. The front detection unit 64 may be provided with a function of identifying the bill P. When the control unit 31 determines that the banknote P can be deposited, the control unit 31 controls the transport unit 5, the seventh to twelfth branching mechanisms 557 to 562, and the first to sixth storage cassettes 261 to 266. The bill P is stored in the first to sixth storage cassettes 261 to 266 according to the denomination. At this time, the bill P is stored in the first to sixth storage cassettes 261 to 266 in a short transport posture. That is, the banknotes P deposited from the banknote transport cassette 15 are stored in the first to sixth storage cassettes 261 to 266 in the same posture as the banknotes P deposited from the deposit unit 21. When the control unit 31 determines that the banknote P cannot be deposited, the control unit 31 performs the first reject transfer control or the second reject transfer control described above.

[Withdrawal processing to banknote transport cassette]
Next, the withdrawal process to the bill transport cassette 15 will be described. In the withdrawal process to the bill transport cassette 15, the paper sheet processing device 1 pulls out the bills P from the first to sixth storage cassettes 261 to 266 in the short transport posture in the longitudinal transport posture. It is stored in the bill transport cassette 15. FIG. 9A is an explanatory diagram of a defect that may occur when the banknote is rotated. FIG. 9B is an explanatory diagram of a method of solving the defect of FIG. 9A.

The operator performs an operation to start a withdrawal process for a predetermined number of banknotes P of a predetermined denomination. The control unit 31 controls the first to sixth storage cassettes 261 to 266, the transport units 5, and the seventh to twelfth branch mechanisms 557 to 562, and transports the bills P one by one to the identification unit 25. At this time, the bill P is transported to the identification unit 25 in a short transport posture. The identification unit 25 identifies the bills P to be sequentially transported, generates a signal indicating the identification result, and outputs the signal to the control unit 31. The control unit 31 determines whether the banknote P can be withdrawn or the banknote P cannot be withdrawn based on the received signal.

When the control unit 31 determines that the bill P cannot be withdrawn, the control unit 31 controls the transport unit 5, the posture change unit 6, and the second and third branching mechanisms 552, 553 to process the bill P. The bill P is stored in the upper reject storage unit 28 without being performed by the posture change unit 6.

When the control unit 31 determines that the bill P can be withdrawn, the control unit 31 determines whether or not to rotate the bill P, as in the case of the deposit processing from the bill transport cassette 15. As a method for determining whether or not to rotate the bill P, at least one of the above-mentioned first to third determination methods can be used. In the withdrawal process, the control unit 31 performs processing based on the first to third determination methods based on the detection result of the bill P by the front detection unit 64 or the identification unit 25. Further, the control unit 31 obtains the interval between the bills P to be carried short.

When the control unit 31 determines that the two banknotes P that are continuously conveyed are not rotated by any of the first to third determination methods, the posture change unit 6 and the second and third determination methods By controlling the branching mechanisms 552 and 553 of the above, the two banknotes P are stored in the upper reject storage unit 28 without being rotated by the posture change unit 6.

The control unit 31 rotates the banknote P in front of the withdrawal transport direction among the two banknotes P that are continuously transported by at least one of the first to third determination methods. When it is determined, the posture change unit 6 is controlled to rotate the bill P, so that the posture of the bill P is changed from the posture of the short transport to the posture of the longitudinal transport. At this time, the control unit 31 performs the same control as the control based on FIGS. 5 and 7A to 7E performed at the time of the deposit processing, so that the posture of the banknote P and the length of the direction Dt of the transport path of the banknote P are long. Regardless of the position of L and the width direction Dw of the transport path of the bill P, the long side Pa of the rotated bill P is parallel to the direction Dt of the transport path, that is, the bill P is in the longitudinal transport posture and the bill P Is located at the center of the width direction Dw of the transport path, and the posture of the bill P is changed. In the following, "a state in which the bill P is in the longitudinal transport posture and the bill P is located at the center of the width direction Dw of the transport path (the center of the long side Pa of the bill P)" is referred to as "withdrawal." Sometimes called "target state". The control unit 31 rotates the first to third direction changing rollers 611 to 613 and the lower roller 62 in the withdrawal process in the direction opposite to that in the deposit process. The posture of the bill P, the length L of the direction Dt of the transport path of the bill P, and the position of the width direction Dw of the transport path of the bill P may be detected by the front detection unit 64 or the identification unit 25. May be done. Further, the set rotation speeds of the first to third direction changing rollers 611 to 613 and the lower roller 62 at the time of withdrawal processing may be the same as or different from those at the time of deposit processing. The position of the banknote P in the width direction Dw after the rotation does not have to be the center.

When the bill P is rotated from the short transport posture to the long transport posture, the bill P is on the right when the bill P at the time of withdrawal is viewed from the rear side (left side in FIG. 4) as shown in FIG. The edge portion (lower edge portion in FIG. 4) faces forward in the withdrawal transport direction, and the left edge portion (upper edge portion in FIG. 4) rotates so as to face rearward in the withdrawal transport direction. Inertia acts forward on the entire bill P in the withdrawal transport direction. On the right edge side of the bill P, the moving direction during rotation and the acting direction of inertia are substantially the same direction. However, on the left edge side of the bill P, the moving direction during rotation and the acting direction of inertia are opposite directions. Therefore, as shown in FIG. 9A, the left edge portion side of the bill P is less likely to rotate than the right edge portion side, and the bill P may bend and wrinkle may occur. Further, since the left edge side is difficult to rotate, the entire bill P is also difficult to rotate, and the bill P may not be in the desired posture due to insufficient rotation.

Therefore, in the present embodiment, the following two configurations are applied in order to suppress the occurrence of such a defect.

In the first configuration, as shown in FIGS. 2, 3A, 4 and 9B, the withdrawal transfer direction D2 of the second direction conversion roller 612 is tilted by an angle θ with respect to the direction Dt of the transfer path. be. In FIG. 9B, the arrows indicating the withdrawal transfer directions of the first to third direction conversion rollers 611 to 613 indicate the transfer speed (rotational speed) by the size thereof.

In such a first configuration, during the rotation of the bill P, the right edge side of the bill P has a second direction changing roller 612 as compared with the case where the withdrawal transport direction D2 is parallel to the direction Dt of the transport path. Pulls diagonally forward to the right. As a result, the occurrence of wrinkles on the bill P is suppressed, and it is also suppressed that the bill P does not have a desired posture due to insufficient rotation. In order to obtain such an effect, the angle θ is preferably a value in the range of 5 ± 2 °.

The second configuration is to drive the third direction changing roller 613 during the rotation of the bill P, as shown in FIGS. 5 and 9B. From time T1, the control unit 31 starts rotating the third direction changing roller 613 in the direction opposite to that of the first and second direction changing rollers 611 and 612. That is, the control unit 31 starts rotating the third direction changing roller 613 so as to convey the bill P to the rear in the withdrawal transfer direction. The control unit 31 maintains the set rotation speed of the third direction changing roller 613 at S3 between the time T2 and the time T3, starts to slow down from the time T3, and returns the set rotation speed to 0 at the time T4.

In such a second configuration, the third direction changing roller 613 positively rotates the bill P so that the left edge side moves backward in the withdrawal transport direction, so that the occurrence of wrinkles on the bill P is suppressed. It is also suppressed that the bill P does not have a desired posture due to insufficient rotation.

When the rotation process of the bill P is completed, the control unit 31 determines whether or not the posture of the bill P is in the withdrawal target state, that is, the bill P is in the longitudinal transport posture and the bill P is in the transport path. It is determined whether or not the state is located at the center of the width direction Dw. For this determination, the detection result of the bill P in the rear detection unit 65 can be used.

For example, the rear detection unit 65 conveys the posture of the bill P after rotation (the inclination angle α1 of the short side Pb with respect to the width direction Dw of the transport path) and the bill P as shown in FIG. 6, as in the case of deposit processing. The position of Dw in the width direction of the road is detected.

The control unit 31 determines whether or not the inclination angle α1 is an angle at which the bill P can be regarded as the posture of longitudinal transportation, that is, whether or not the deviation of the inclination angle α1 from 0 ° is less than the allowable angle. The control unit 31 determines whether or not the position of the banknote P in the width direction Dw of the banknote P can be regarded as the center position of the width direction Dw of the banknote P, that is, from the center position of the width direction Dw of the banknote P. Determine if the deviation is less than the permissible deviation amount.

When the deviation of the inclination angle α1 from 0 ° is less than the permissible angle and the deviation from the center position of the width direction Dw of the transport path is less than the permissible deviation amount, the control unit 31 withdraws the bill P. Judge that the target state is reached. When the deviation of the inclination angle α1 from 0 ° is equal to or greater than the permissible angle, or the deviation from the center position of the width direction Dw of the transport path is equal to or greater than the permissible deviation amount, the control unit 31 is in the withdrawal target state. It is judged that it is not.

When the control unit 31 determines that the rotated banknote P is not in the withdrawal target state, the control unit 31 controls the transport unit 5 and the third branching mechanism 553 to store the banknote P in the upper reject storage unit 28. do.

When the control unit 31 determines that the rotated bill P is in the withdrawal target state, the control unit 31 controls the transport unit 5, the third branch mechanism 553, the deposit / withdrawal unit 23, and the bill transport cassette 15, to control the bill. Ps are stored one by one in the bill transport cassette 15. At this time, the bill P is stored in the bill transport cassette 15 in the longitudinal transport posture.

<Action and effect of the embodiment>
The paper leaf transport device 4 inserts the banknote P inserted from the deposit section 21 (first receiving section) into the storage section 26 in the short transport posture (first posture) without changing the posture. Store. The paper leaf transport device 4 changes the posture of the bill P inserted from the bill transport cassette 15 in the longitudinal transport posture (second posture) via the deposit / withdrawal section 23 (second receiving section). The unit 6 changes the posture for short-handed transportation and stores it in the storage unit 26. Therefore, regardless of whether the bill P is inserted into the paper leaf transport device 4 in the short transport posture or in the longitudinal transport posture, it can be stored in the storage unit 26 in the same posture.

The paper leaf transport device 4 changes the posture of the banknote P to one of the longitudinal transport posture and the short transport posture due to the difference in rotation speed between the first direction change roller 611 and the second direction change roller 612. Change from the posture to one of the long-distance transport posture and the short-hand transport posture. Therefore, for example, the posture of the longitudinal transport can be changed to the posture of the short transport by one rotation process using the first direction change roller 611 and the second direction change roller 612. It is possible to suppress the increase in size of 4. In addition, control during rotation processing becomes easy.

When the paper leaf transport device 4 rotates the bill P, the rotation speed of the first direction changing roller 611 is changed to a speed different from the rotation speed before and after changing the posture of the bill P, and the second The rotation speed of the direction changing roller 612 is not changed from the rotation speed before and after changing the posture of the bill P. In this way, since the rotation speed of only the first direction changing roller 611 is changed, it becomes easy to control when the bill P is rotated.

The banknote P is transported in a direction away from the first direction changing roller 611 toward the downstream side (rear side) of the third transport path 513 when the banknote P is transported behind the paper leaf processing device 1. As described above, the second direction changing roller 612 is provided. Therefore, when the banknote P transported behind the paper leaf processing device 1 is rotated, it is possible to suppress the occurrence of wrinkles on the banknote P, and it is possible to prevent the banknote P from being in a desired posture due to insufficient rotation.

The outer peripheral surfaces 614A and 615A in the cross section along the respective rotation axes of the first and second contact rollers 614 and 615 are formed in a curved surface shape. Therefore, the contact area between the first and second contact rollers 614 and 615 and the bill P can be reduced, and the bill P can be smoothly rotated. Further, even when the first and second contact rollers 614 and 615 are tilted and fixed in a state different from the design due to variations in parts and the like, the first and second contact rollers 614 and 615 and the bill P The contact state can be the same as when it is fixed as designed.

The paper leaf transport device 4 controls the lower roller 62 and the upper roller 63 to be in contact with the bill P when the bill P is not rotated, and when the bill P is rotated, the upper roller 63 is moved to the bill P. It is controlled to the second state where it does not come into contact with P. Therefore, when the bill P is not rotated, the bill P can be smoothly conveyed by the lower roller 62 and the upper roller 63. When the bill P is rotated, the upper roller 63 does not come into contact with the bill P, so that it is possible to eliminate the risk of the bill P being damaged during rotation, such as when the upper roller 63 is kept in contact with the bill P. Above, the bill P can be rotated smoothly.

The paper leaf transport device 4 separates the upper roller 63 from the bill P at the same time as the rotation of the bill P starts. Therefore, until the start of rotation of the bill P, the bill P can be smoothly conveyed by the contact between the lower roller 62 and the upper roller 63.

The paper leaf transport device 4 brings the upper roller 63 into contact with the bill P at the same time as the rotation of the bill P is completed. Therefore, it is possible to prevent the bill P from rotating too much due to inertia during rotation.

The lower roller 62 is provided with an inclined surface 622A that is inclined so as to approach the axis of the lower roller 62 toward the outside in the axial direction of the lower roller 62. Therefore, the rotating bill P can be brought into contact with the inclined surface 622A of the lower roller 62 and moved along the inclined surface 622A. As a result, the bill P can be smoothly rotated.

When the paper sheet transport device 4 rotates the banknote P, the third direction changing roller 613 and the third contact roller 616 are brought into contact with the banknote P, and the third direction changing roller 613 is brought into contact with the first and first third direction changing rollers 613. The third contact roller 616 is not brought into contact with the bill P when the paper sheets are rotated in the direction opposite to the direction changing rollers 611 and 612 of No. 2. Therefore, when the bill P is rotated, it is possible to suppress the occurrence of wrinkles on the bill P, and it is possible to prevent the bill P from being in a desired posture due to insufficient rotation. When the bill P is not rotated, the bill P can be smoothly conveyed.

The paper leaf transport device 4 is configured so that the posture of the bill P can be changed from, for example, the posture of the long transport to the posture of the short transport by rotating the bill P by 90 ± 20 °. Therefore, as shown in the figure on the right side of FIG. 7C or FIG. 7D, even when the vertically transported banknotes P4 and P5 are tilted, as shown in the figure on the left side of FIG. 7C or FIG. Can be in a posture.

The paper leaf transport device 4 is the interval between two bills P that are continuously transported based on the detection result of the rear detection unit 65 (second detection unit) during the deposit processing from the bill transport cassette 15. (First interval) is obtained, and if the obtained interval is less than the threshold value (first threshold value), it is determined that the two banknotes P are not rotated. When the paper leaf transport device 4 determines that the bill P is not rotated and performs the first reject transport control, the transport unit 5 and the second, sixth to ninth branching mechanisms 522, 556 to 559 (second). The two banknotes P that are determined not to be rotated are held in the temporary holding section 30 by controlling the branching section), and after the processing for all the banknotes P to be deposited is completed, the transport section 5 and the second and second bills P are used. By controlling the 6th to 9th branching mechanisms 522, 556 to 559 and the 3rd branching mechanism 553 (first branching portion), the bill P held in the temporary holding portion 30 is stored in the upper reject storage portion 28 (first branching portion). Store in the reject storage section). When the paper leaf transport device 4 determines that the bill P is not rotated and performs the second reject transport control, the transport unit 5 and the second, fourth to ninth branching mechanisms 522, 554 to 559 (third). The two bills P determined not to be rotated are stored in the counting reject storage unit 29 (second reject storage unit) by controlling the branching portion). Therefore, it is possible to prevent a problem that may occur when two banknotes P having an interval of less than the threshold value are rotated, that is, the transfer and the identification in the identification unit 25 cannot be performed properly.

The paper leaf transport device 4 detects the posture of the bill P in the rear detection unit 65 (detection unit) at the time of deposit processing from the bill transport cassette 15, and based on this detection result, the posture of the bill P is longitudinally determined. Change from the transport posture to the short transport posture. At the time of withdrawal processing to the bill transport cassette 15, the paper leaf transport device 4 detects the posture of the bill P by the front detection unit 64 or the identification unit 25, and based on the detection result, the posture of the bill P is determined. Change from the short transport posture to the long transport posture. In this way, by controlling the rotation state of the bill P according to the posture of the bill P before rotation, the posture of the bill P can be changed to a desired posture regardless of the posture of the bill P before rotation. ..

At the time of deposit processing from the bill transport cassette 15, the paper leaf transport device 4 detects the length L of the direction Dt of the transport path of the bill P in the rear detection unit 65 (detection unit), and based on this detection result. The linear transport distance H of the bill P, that is, the timing of the start of rotation of the bill P is adjusted so that the rotated bill P is located at a predetermined position in the width direction Dw of the transport path. At the time of withdrawal processing from the bill transport cassette 15, the paper leaf transport device 4 detects the length L of the direction Dt of the transport path of the bill P by the front detection unit 64 or the identification unit 25, and is based on this detection result. Then, the linear transport distance H of the bill P is adjusted so that the rotated bill P is located at a predetermined position in the width direction Dw of the transport path. Therefore, even when the banknote P before rotation is tilted or the banknotes P having different sizes are transported, the position of the transport path Dw of the banknote P after rotation can be set to a predetermined position. can. Therefore, it is possible to prevent the rotated bill P from colliding with the side wall of the transport path, and the bill P can be smoothly transported.

The paper leaf processing device 1 is provided with a cassette mounting unit 22 on which the bill transport cassette 15 (first cassette) is mounted. In this way, the banknote transport cassette 15 having a mechanism for discharging the stored banknotes P can be used to improve the efficiency of the deposit process.

The paper leaf transport device 4 is used at the time of deposit processing from the bill transport cassette 15 based on the detection result of the bill P by the front detection unit 64 (first detection unit) or the identification unit 25 (first detection unit). It is determined whether or not the posture of the bill P after rotation can be regarded as a short-handed transport. When the paper leaf transport device 4 determines that it can be regarded as a short transport, the paper leaf transport device 4 stores the bill P in the storage unit 26. When the paper leaf transport device 4 determines that it cannot be regarded as short transport and performs the first reject transport control, the transport unit 5 and the second, sixth to ninth branching mechanisms 522, 556 to 559 ( The second branch portion) is controlled to hold the bill P, which is determined not to be regarded as short-hand transportation, in the temporary holding portion 30. After the processing of all the banknotes P to be deposited is completed, the paper leaf transport device 4 includes the transport unit 5 and the second, sixth to ninth branching mechanisms 522, 556 to 559 and the third branching mechanism 553 ( The first branch portion) is controlled, and the bill P held in the temporary holding portion 30 is stored in the upper reject storage portion 28 (first reject storage portion). When the paper leaf transport device 4 determines that it cannot be regarded as short transport and performs the second reject transport control, the transport unit 5 and the second, fourth to ninth branch mechanisms 522, 554 to 559 are moved. The bill P, which is controlled and determined not to be regarded as short transport, is stored in the counting reject storage unit 29 (second reject storage unit). Therefore, the banknotes P can be stored in the storage unit 26 in a state where the postures of the banknotes P are substantially unified. In particular, when the first reject transfer control is performed, all the banknotes P whose posture cannot be regarded as short transfer can be stored in the upper reject storage unit 28 by one transfer process.

The paper leaf transport device 4 changes the posture of the bill P, which is unwound from the storage unit 26 by short-hand transport, to the longitudinal transport by the posture change unit 6 at the time of withdrawal processing to the bill transport cassette 15. It is stored in the bill transport cassette 15. Therefore, the paper leaf transport device 4 can store the bill P in the bill transport cassette 15 in an appropriate posture.

The paper leaf transport device 4 determines whether or not to rotate the bill P at the time of withdrawal processing to the bill transport cassette 15. When the first determination method is used, the paper leaf transport device 4 obtains and obtains the distance between two bills P to be continuously conveyed based on the detection result in the front detection unit 64 or the identification unit 25. If the interval is less than the threshold value, it is determined that the two banknotes P are not rotated. When the second determination method is used, the paper sheet transport device 4 is based on the detection results of the front detection unit 64 (third and fourth detection units) or the identification unit 25 (third and fourth detection units). The interval (second interval) between the two bills P that are continuously conveyed is obtained. The paper leaf transport device 4 is based on the obtained interval and the position of the two bills P in the width direction Dw of the transport path detected by the front detection unit 64 or the identification unit 25. The predicted interval (third interval) when the bill P is rotated is obtained. When the obtained prediction interval is less than the threshold value (third threshold value), the paper leaf transport device 4 determines that the two bills P are not rotated. When the third determination method is used, the paper sheet transport device 4 has a front detection unit 64 (third, fourth, fifth detection unit) or an identification unit 25 (third, fourth, fifth detection unit). ), The predicted interval is obtained based on the interval of the banknotes P, the position of the Dw in the width direction of the transport path of the banknotes P, and the size of the banknotes P, and the two banknotes P are rotated. Judge whether or not. The paper leaf transport device 4 controls the transport unit 5 and the third branch mechanism 553 (first branch unit) to store the two banknotes P determined not to rotate in the upper reject storage unit 28 (first branch unit). Store in the reject storage section). Therefore, it is possible to prevent a problem that may occur when two banknotes P having an interval of less than the threshold value are rotated, that is, the transfer cannot be performed properly. In particular, when the second determination method is used, when the two banknotes are rotated in order to determine whether or not to rotate the two banknotes P based on the predicted interval when it is assumed that the two banknotes P have been rotated. It is possible to appropriately judge the risk of occurrence of defects in. Further, when the third determination method is used, the size of the banknote P is also taken into consideration when the prediction interval is obtained, so that the calculation accuracy of the prediction interval can be improved.

For example, the store manager can insert the bill P into the second deposit section 21B from the back office in a short-handed posture, so that the deposit processing time can be shortened.

<Other variants>
Only one bill P may be inserted into the paper leaf processing devices 1, 1A and 1B. In this case, the bill P is inserted so as to be transported in a short direction and stored in a longitudinal transport posture. It may be stored in the storage unit 26, or it may be inserted so as to be vertically transported and stored in the storage unit 26 in a short transport posture. For example, the paper leaf processing device 1 does not have to be provided with the deposit section 21 or the cassette mounting section 22.
