BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing apparatus such as a bill depositing / dispensing apparatus and a ticket issuing apparatus.

[0002]

2. Description of the Related Art Generally, in a paper sheet processing apparatus, for example, a banknote depositing / dispensing apparatus, a banknote fed from a stacking unit is placed on a conveying path by one unit.
The paper is conveyed one by one, and the position is monitored by the banknote position monitoring sensor provided on the conveyance path, and the authenticity, damage, denomination, and front / back determination result by each discrimination means in the bill discrimination section provided on the conveyance path are determined. Based on this, the transfer distribution mechanism is operated to perform various processes such as deposit, withdrawal, and reject.

FIG. 2 is a circuit block diagram of a conventional bill depositing / dispensing device. In FIG. 2, the banknote deposit / withdrawal device controller 20
Reference numeral 0 is a program ROM 2 that is composed of a microcomputer (CPU) and its peripheral circuits and is connected via a bus.
The control flow information stored in No. 03 is referred to, and each unit is controlled while using the working RAM 204 according to the information. The control interface circuit 201 is connected to a higher-order control unit (not shown), receives an operation instruction command, transfers the operation instruction command to the banknote deposit / withdrawal device control unit 200, and sends a response of the operation result to the banknote deposit / withdrawal device control unit 20.
It is received from 0 and returned to the upper control unit.

The input / output interface circuit (I / O interface circuit) 202 is a bill deposit / withdrawal device control unit 2.
In response to the instruction of 00, each unit of the banknote pay-in / pay-out device is operated, and the status and operation result of each unit is notified to the banknote pay-in / pay-out device control unit 200. Here, a motor driver 205, a magnet driver 206, a key switch reading circuit 207, an optical sensor reading circuit 20.
8. The bill validator control unit 209 is connected.

The motor driver 205 is connected to a motor group 211 arranged at various places of the bill depositing / dispensing apparatus, and operates or stops each motor according to each processing stage. Magnet driver 20
Reference numeral 6 is connected to the magnet group 212 of each unit, and turns on or off the magnet according to each processing stage. The key switch reading circuit 207 and the optical sensor reading circuit 208 are connected to the switch group 213 of each part and the optical sensor group 214 for monitoring the conveyance and stacking of banknotes, and detect these pieces of information. The bill discriminating unit control unit 209 is connected to the plurality of bill discriminating unit sensor groups 215 of the bill discriminating unit, discriminates the fed bills, and notifies the bill depositing / dispensing device control unit 200 of the result. .

In such a circuit block configuration,
Target actuators or sensors, for example, motor drivers 205 scattered around the bill depositing / dispensing device.
The wiring between the motor group 211, the magnet driver 206, the magnet group 212, the key switch reading circuit 207, the switch group 213, the optical sensor reading circuit 208, the optical sensor group 218, etc. is a relay connector or a relay printed circuit board. Is done through. This is to reduce the circuit cost for wiring. In addition, the control method is such that the number of actuators and sensors exceeds several tens to 100 in some cases, so instead of constantly monitoring the status inside the device, monitoring the status change at regular intervals,
Only the items that have changed are processed.

FIG. 3 is a transition diagram of a conventional device control process. The state of control is schematically represented in this figure. First, Figure 2
The banknote pay-in / pay-out device control unit 200 shown in (1) is prepared with an interval timer interrupt that interrupts at regular intervals.
Normally, the banknote pay-in / pay-out device control unit 200 executes a process called a base level. Also, working RAM
An area for storing the subroutine number requesting the processing at the interval level is secured on the 204 and is referred to. If the request is made, the processing is executed, and if the processing is completed, the requested subroutine number Is deleted, and it is further referred to whether there is another request (process a in the figure). If there is no request, nothing is executed until the next interval timer interrupt occurs.

When an interval timer interrupt occurs, the bill depositing / dispensing device control section 200 suspends the processing so far, monitors the state of each sensor, and stores the previous sensor state on the working RAM 204. If the result is different from the previous one, the data in the working RAM 204 is updated, and the subroutine number of the process for which a request is generated is stored in a prescribed area on the working RAM 204. (Processes b to e in the figure). Furthermore, the operating time counter stored in the working RAM 204 is updated for each actuator, and when the counter reaches a specified value, the subroutine number of the process for which a request is generated in accordance with that is specified in the specified area on the working RAM 204. To store. When this process ends, the process returns to the base level process again, and restarts from the process executed immediately before entering the interval timer interrupt.

On the other hand, for a device with a high degree of urgency such as a device abnormality, the process is immediately executed, so that it is assigned to an interrupt process having a higher priority than the interval timer interrupt (process x in the figure). If it occurs, the processing up to now is temporarily suspended, the processing is performed, and when the processing is completed, the original processing is returned to. By doing so, the state of the device is monitored as finely as possible, and a plurality of processes are operated as if they are processed in parallel.

By the way, recent LS
The progress of I technology is remarkable, and the unit price of circuit parts such as logic circuits, memories, and microprocessors is decreasing year by year. On the other hand, labor costs for assembly work are increasing year by year. For this reason, in the device having the above-mentioned configuration, although the circuit cost is low, the labor cost related to wiring is high, and the cost is high as a whole.

On the other hand, not only the banknote depositing / dispensing processing apparatus described above, but also the paper sheet processing apparatus tends to increase in the number of sensors and actuators as the function and performance of the sheet processing apparatus have increased in recent years. There is more and more work to be done in the timer interrupt. Therefore, in the above processing method, if the interval of the interval timer is kept constant, the base level processing which is the actual processing cannot be sufficiently executed, and the capability of the microprocessor must be successively increased. It's gone.

However, the speed at which the capability of the microprocessor is improved is greatly different from the speed at which the device is required to have higher functionality and higher performance, and it is becoming difficult for the microprocessor to cope with this. Furthermore, by increasing the capability of the microprocessor, the programs created up to now may not be used as they are. For example, if a function change or the like is performed in the expectation of finer control, the processing time may be broken.

The present invention has been made by paying attention to the above points, and diverts the manufacturing cost by arranging the control parts centrally and diverts it in response to the demand for higher functionality and higher performance. In order to realize a highly flexible processing method, a plurality of control units are dispersedly arranged in the device, and the purpose is to provide a highly expandable device in which the control units can cooperate with each other to perform processing. Is.

(FIG. 8-T3) By this, the bill is fed out, and when the feeding sensor 13c reads from the sensor reading circuit 87-3 that the feeding is normally completed, the unit controller 80-3 determines the remaining portion to be fed. The number of banknotes is reduced from 3 to 2, and the working RAM 84-
A tag for the bill validator 50 is generated on the tag 3. As shown in FIG. 7, the tag 180 is given one for each banknote to be conveyed, and the name 181 of the unit that paid out the banknote and the name 18 of the unit of the transfer destination
2. The serial number 183 in one transaction, the name 184 of the unit that sent this tag, and other control information 185 such as a flag for determining whether the bill is the final bill.

Therefore, here, the payout unit is the denomination type stacker unit 10c, and the destination unit is the bill discriminating unit 5
0, the serial number is 1, the tag sending unit is the money type stacker unit 10c, and the final bill flag is off. Subsequently, the sensor reading circuit 8 indicates that the leading edge of the bill reaches the next unit by the bill position detection sensor 62-9.
When detected from 7-3, the unit controller 80-3 detects the tag generated on the working RAM 84-3 and is the leading unit in the direction of the bill discriminating unit 50.
Send to b. As a result, the unit control unit 80-2 of the denomination-type stacker unit 10b temporarily stores the received tag in the working RAM 84-2, and enters bill conveyance monitoring.

(FIG. 8-T4) The unit control unit 80-2 of the denomination-type stacker unit 10b which has started the transportation of banknotes is set to 1
Unless the banknote position detection sensor 62-8 detects that the leading edge of the banknote has reached the next unit, unless the first banknote is abnormal, the tag delivery unit name stored in the working RAM 84-2. Stacker section 10 by denomination
The bill is changed to b and is sent to the denomination type stacker unit 10a which is the leading unit in the direction of the bill discriminating unit 50.

(FIG. 8-T5) In this way, when the banknotes and the tags corresponding thereto are sequentially conveyed and transferred between the units and reach the banknote discrimination section 50, the unit control section 80- of the banknote discrimination section 50- 7 is a working RAM 8 tag
It is stored on the 4-7 and waits for the discrimination result of the bill discriminating circuit 88. When the bill discriminating circuit 88 determines from the output result of the discriminating sensor group 51-7 that the bill discriminating circuit 88 is a normal bill, the unit controller 80-7 receives the notice and the working unit RAM 80-7 determines that the working RAM is working RAM.
The delivery unit name of the tag stored on the 84-7 is changed to the bill discriminating unit 50, and the transport destination unit name is used as the deposit / withdrawal stacker unit 20 and the deposit / withdrawal stacker unit 20 that is the leading unit in the transport destination direction. The tag is sent to the denomination type stacker unit 10c, which is a payout unit.

(FIG. 9-T6) As a result, the unit control section 80-4 of the deposit / withdrawal stacker section 20 stores the received tag in the working RAM 84-4, and the tag to which the own unit is the destination is attached. By receiving the banknotes, the banknote stacking control is performed, and the unit controller 80-3 of the denomination type stacker unit 10c, which is a payout unit, confirms that the first banknote has been normally dispensed. Unit control unit 80-4 of the deposit / withdrawal stacker unit 20 that has entered the accumulation monitoring
Is a bill position detection sensor 62-1 and a feeding sensor 2
3. Based on the output of the residual sensor 24, it is monitored whether the integration is completed, and when the integration is completed safely, the working RAM
Delete the tags stored on 84-4.

(FIG. 8-T7) On the other hand, the money type stacker unit 1
The unit control unit 80-3 of 0c has started feeding the next banknote at the time when the first banknote has been conveyed to the next unit. Then, when it is detected that the payout has been completed normally, the number of remaining banknotes to be paid out is reduced from 2 to 1 and a tag for the second banknote is generated, as in the case of the first banknote.

(FIG. 8-T8) As for the second tag, the payout unit is the denomination stacker unit 10c, the destination unit is the bill validator 50, the serial number is 2, and the tag sending unit is the denomination stacker unit 10c. The bill flag is off. Subsequent processing is the same as that of the first sheet, and the tag and the bill are sent to and conveyed to the next unit.

Further, when the second banknote has been conveyed to the next unit, the third banknote is fed out, and similarly, when the normal delivery is completed, the number of banknotes to be reeled out is reduced from one to zero, and the tag is removed. To generate. The tag at this time is the same as the previous two tags except that the serial number is 3. Then, the tag is transferred at the same time when the bill is sent to the next unit.

(FIG. 9-T9) As a result, the unit control section 80-3 of the denomination type stacker section 10c finishes the feeding operation, and generates the following tags on the working RAM 84-3. That is, the payout unit is the denomination stacker unit 10c, the destination unit is the bill validator 50, the serial number is 0, and the tag sending unit is the denomination stacker unit 1.
0c, the last bill flag is a tag that is turned on.

Now, the second bill is the bill discrimination circuit 8
If it is determined in 8 that the bill is a dirty bill, the bill validator 5
The unit controller 80-7 of 0 is the working RAM 84.
The second tag stored on the -7 is composed of the receipt / withdrawal stacker unit 20 which is the leading unit in the transport direction and the delivery unit with the transport destination unit as the reject stacker unit 40 and the tag delivery unit as the bill discriminating unit 50. It is transferred to a certain money type stacker unit 10c.

(FIG. 9-T10) At this time, since the third stack of the denomination-type stacker unit 10c has already been completed, the number of banknotes to be delivered is 0. When it is received from 50, the unit controller 80-3 increases the number of bills to be paid out from 0 to 1, and deletes the above-mentioned tag whose final bill flag is on from the working RAM 84-3. Furthermore, since the number of bills that can be dispensed has decreased by one, the feeding operation is started again.

(T11 in FIG. 9) When the feeding operation is restarted and the feeding is completed in this way, the unit controller 80-3 again sets the number of banknotes to be fed out from 1 to 0.
The number is reduced to the number of sheets, and the same tag as that of the first to third sheets is generated on the working RAM 84-3 with the serial number 4 and other data. The subsequent processing is performed in the same manner as the third sheet, and when the tag is transferred to the next unit, the working RAM 84
A tag whose last bill flag is on is generated on -3.

On the other hand, the unit control section 80-4 of the deposit / withdrawal stacker section 20 drives the sorting magnet 63m1 to sort the sorting tag because the destination of the received second tag is the reject stacker section 40. When the mechanism 63-1 is placed on the side of the reject stacker unit 40, the conveyance control is entered, and when the bill position detection sensor 62-2 detects that the leading edge of the bill has entered the reject stacker unit 40, the delivery unit is deposited and withdrawn. Change to the stacker unit 20 and send the tag to the reject stacker unit 40. As a result, the unit controller 8 of the reject stacker unit 40
0-6 stores the tag in the working RAM 84-6 and starts the integration monitoring, and erases the tag when the integration is normally completed.

(FIG. 10-T12) Now, the third and fourth bills are judged by the bill discriminating section 50 to be normal 1,000 bills,
When the tag, which is the transfer destination deposit / withdrawal stacker unit 20 having the serial number 4, is transferred from the unit control unit 80-7 of the bill discriminating unit 50 to the denomination type stacker unit 10c, the unit of the denomination type stacker unit 10c is transferred. The control unit 80-3 confirms that the last banknote delivered from its own unit is normal and the number of banknotes to be delivered is 0, so that the working R
The unit control unit 80-of the denomination-type stacker unit 10b uses the tag whose final bill flag stored in the AM 84-3 is ON.
2 and the transport motor 61-10 is stopped.

The unit controller 80 that receives this tag
-2, since the number of bills to be fed out by its own unit is 0, the tag sending unit is immediately sent as the denomination-type stacker unit 10b to the denomination-type stacker unit 10a, and since the own unit has no bills to be conveyed, it is conveyed. Motor 61-
Stop 8.

(FIG. 10-T13) Now, the unit control unit 80-1 of the denomination type stacker unit 10a which has received the tag of the final bill flag ON from the denomination type stacker unit 10b has two bills to be fed out by its own unit. Therefore, the tag is immediately deleted, and the motor driver circuit 85-1 is instructed to start the stacker motor so that the stacking mechanism 11a is joined to the feeding mechanism 12a.
The payout motor is driven to draw out one bill.

As a result, when the sensor reading circuit 87-1 reads out that the bill has been fed out and the feeding-out sensor 13a has completed the feeding out normally, the unit controller 80-1 determines the number of bills to be fed out from 2 to 1
The number of sheets is reduced to a working RAM 84-1 and the payout unit generates a denomination-type stacker unit 10a, the destination unit a bill discrimination unit 50, a serial number 5, the tag sending unit generates a denomination-type stacker unit 10a, and a final bill flag off tag is generated. To do.

Subsequently, when the bill position detection sensor 62-7 detects that the leading edge of the bill reaches the next unit, the unit controller 80-1 causes the working RAM 84 to operate.
The tag stored on -1 is sent to the bill discriminating unit 50 which is the leading unit in the bill discriminating unit 50 direction. This allows
The unit control unit 80-1 of the denomination type stacker unit 10a enters the next payout operation and receives the tag, and the bill discriminating unit 5
The unit controller 80-7 of 0 sets the tag to the working RAM.
It is stored on 84-7 and waits for the discrimination result of the bill discriminating circuit 88.

When the bill discriminating circuit 88 determines from the output result of the discrimination sensor group 51 that the bill discriminating circuit 88 is normal, upon receipt of the notice, the unit controller 80-7 causes the working RA
The delivery unit of the tag stored on the M84-7 is the bill validator 50, and the destination unit is the deposit / withdrawal stacker 20.
And the tags are sent to the deposit / withdrawal stacker unit 20 which is the leading unit in the transport destination direction and the coin type stacker unit 10a which is the payout unit. As a result, the unit control unit 80-4 of the deposit / withdrawal stacker unit 20 stores the received tag on the working RAM 84-4, and performs stacking monitoring by the self unit receiving the bill of the tag which is the transport destination, The unit controller 80-1 of the denomination type stacker unit 10a, which is a payout unit, confirms that the corresponding banknote has been normally dispensed.

(FIG. 10-T14) The unit control section 80-4 of the deposit / withdrawal stacker section 20 which has entered the accumulation monitoring, based on the outputs of the bill position detection sensor 62-1, the feeding sensor 23 and the residual sensor 24. Is completed and the tag stored in the working RAM 84-4 is erased when the integration is successfully completed.

On the other hand, when the unit control section 80-1 of the denomination type stacker section 10a detects that the feeding operation is completed and the feeding operation is completed at the time when the first sheet of the own unit is conveyed, , The number of bills to be paid out is reduced from 1 to 0, and the tag of serial number 6 is generated.

When the tags are sent to the bill discriminating section 50 again after the conveyance is completed, the payout unit is the denomination stacker section 10a, the destination unit is the bill discriminating section 50, the serial number is 0, and the tag sending unit is the denomination stacker section. 10
a, the tag of the last bill flag on is generated.

The bill discriminating unit 50 determines that all the fed bills are normal bills, and the unit control unit 80-7 of the bill discriminating unit 50 becomes the transfer destination deposit / withdrawal stacker unit 20 having the serial number 6. The tag is a stacker unit 10a by denomination
When it is transferred to the unit control unit 80-1, the unit control unit 80-1 determines that the final bill delivered from its own unit is normal and the number of bills to be delivered is 0. The tag of the last bill flag on stored in the bill is sent to the bill validator 50,
The transport motors on the transport paths 60-6 and 60-7 are stopped.

Upon receipt of this tag, the unit control section 80-7 of the bill discriminating unit 50 immediately changes the tag delivery unit to the bill discriminating unit 50, changes the transport destination to data indicating all the units, and outputs the tag in the dispensing direction. The transfer motor is stopped at the transfer path 60-3 because there is no banknote to be transferred in the own unit while the transfer is performed to the deposit / withdrawal stacker unit 20 which is the leading unit of the transfer unit.

(FIG. 10-T15) Now, the unit control section 80-4 of the deposit / withdrawal stacker section 20, which has received the tag of the last bill flag ON, operates this tag because there is a bill for accumulation monitoring in its own unit. When it is temporarily stored in the RAM 84-4 and it is detected that all the banknotes have been stacked, the tag sending unit is set as the pay-in / pay-out stacker unit 20 and the reject stacker unit 4 which is the leading unit in the pay-out direction.
0, and the transport motors on the transport paths 60-1 and 60-2 are stopped.

Since the unit controller 80-6 of the reject stacker unit 40 has no banknotes to be conveyed and accumulated in its own unit and there is no unit in the withdrawing direction after the own unit, the operation end message is sent to the bill depositing / withdrawing device controller 70. Transfer to. The banknote pay-in / pay-out device control unit 70 monitors the tags transmitted / received between the units via the network control circuit 72 from issuing the pay-out operation start instruction to receiving the operation end message. If there is no logical defect such as omission, the upper device is notified that the withdrawal operation has been completed.

As a result, when the higher-level device sends a discharge command to the bill depositing / dispensing device control unit 70, the bill depositing / dispensing device control unit 70 receives this and the unit control unit 80- of the depositing / dispensing stacker unit 20- 4, the unit controller 80-4 drives the shutter motor to open the opening / closing mechanism 25, and monitors the removal of bills by the customer using the residual sensor 24.

When the removal of the customer is detected, the unit controller 80-4 drives the shutter motor again to close the opening / closing mechanism 25 and notifies the bill depositing / withdrawing device controller 70 that the discharging is completed. . With this,
The discharging operation ends, and the bill depositing / dispensing device control unit 70 notifies the upper-level device of normal end, and at the same time, the entire unit control unit 80
The payout operation ends when each unit enters the standby state.

<Depositing Operation> FIG. 4 is a conceptual diagram of the depositing operation. (FIG. 11-T1) In the case of depositing, first, a banknote suction instruction comes from the host device via the control unit interface circuit 71. Thereby, the banknote pay-in / pay-out device control unit 70 instructs the unit control unit 80-4 of the pay-in / pay-out stacker unit 20 to take in the banknotes. In response to this, the unit controller 8
0-4 drives a shutter motor to open / close mechanism 2
5 is opened and the residual sensor 24 monitors the insertion of bills by the customer.

When the insertion of the customer is detected, the unit controller 80-4 drives the shutter motor again to close the opening / closing mechanism 25 and notifies the bill deposit / withdrawal device controller 70 that the suction is completed. To do. Here, it is assumed that the customer has inserted one 5,000 ticket and two 000 tickets. As a result, when the banknote pay-in / pay-out device control unit 70 notifies the upper-level device of the suction completion, the upper-level device instructs the depositing operation.

Upon receipt of the deposit operation instruction, the banknote deposit / withdrawal device control section 70 first notifies all unit control sections 80 that the operation after this instruction is the deposit operation.
Next, the unit controller 80-4 of the deposit / withdrawal stacker unit 20
Is notified that the number of separated sheets is until the inhaled bills are exhausted. Subsequently, the banknote deposit / withdrawal device control unit 70
Is the stacker unit 10 of the denomination-based stacking unit for all the bills that have been successfully discriminated against the unit control unit 80-7 of the bill discriminating unit 50.
a, the five thousand note is the denomination type stacker unit 10b, the thousand note is the denomination type stacker unit 10c, and the conveyance destination of the non-discriminating ticket is the temporary holding unit 30. When the withdrawal operation start instruction is issued to all the units, the banknote pay-in / pay-out device control unit 70 starts tag monitoring.

(FIG. 11-T2) Gold type stacker unit 10
When receiving the deposit operation start instruction, each unit controller 80 of a, 10b, 10c, the deposit / withdrawal stacker unit 20, the temporary storage unit 30, and the bill discriminating unit 50 drives the transport motor in the deposit direction. Instruct 85. Note that the reject stacker unit 40 does not need to participate in the deposit operation, so this process is not performed. In addition, since there is no bill conveyed from the reject stacker unit in the conveyance path 60-2 of the deposit / withdrawal stacker unit 20, the conveyance motor 6
The drive of 1-2 is not performed.

When the specified time for all the motors to reach the specified number of revolutions elapses from the receipt of the deposit operation instruction, the unit controller 80-4 of the deposit / withdrawal stacker unit 20 instructs the motor driver circuit 85-4 to The payout motor is driven to draw out one bill.

(FIG. 11-T3) As a result, the bill is fed out, and when the feeding sensor 23 reads from the sensor reading circuit 87-4 that the feeding has been completed normally, the unit controller 80-4 causes the working RAM 84-
4, a payout / withdrawal stacker unit 20, a delivery destination unit with a banknote discriminating unit 50, a serial number of 1, a tag sending unit with a payout / withdrawal stacker unit 20, and a final bill flag of OFF are generated on the above 4. Subsequently, when the bill position detection sensor 62-1 detects that the front end of the bill has reached the next unit, the unit control unit 80-4 identifies the tag stored in the working RAM 84-4 as the bill discrimination unit 50. Send to.

(FIG. 11-T4) In response to this, the unit control section 80-7 of the bill discriminating section 50 makes the tag working R.
It is stored on the AM 84-7 and the discrimination result of the bill discriminating circuit 88 is awaited. When the bill discrimination circuit 88 determines from the output result of the discrimination sensor group 51 that the banknote discrimination circuit 88 is a normal five thousand note, the unit controller 80-7 receives the notification and the working controller 80-7
The tag sending unit stored on the AM84-7 is changed to the bill discriminating unit 50 and the conveyance destination is changed to the denomination stacker unit 10b, and at the same time when the bill is conveyed to the next unit, the leading unit in the denomination stacker unit 10b direction. And the deposit / withdrawal stacker unit 20 which is a payout unit.

(T5 in FIG. 11) As a result, the unit controller 80-1 of the denomination-type stacker unit 10a stores the received tag in the working RAM 84-1 and the transfer destination is not the own unit. to go into. Further, the unit controller 80-4 of the deposit / withdrawal stacker unit 20, which is a payout unit, confirms that the first bill has been normally deposited. Here, in the depositing operation, it is not necessary to manage the number of normally dispensed sheets, but the discrimination result is sent to the depositing / dispensing stacker unit 20 which is the dispensing unit because an abnormal medium is inserted and the apparatus itself is damaged. This is to stop the feeding when the non-discriminating tickets are consecutive in order to suppress

Now, the unit control section 80-1 of the denomination-type stacker section 10a which has started the conveyance monitoring monitors the conveyance distance after the output of the bill position detection sensor 62-7 is turned off, and the bill is transferred to the next unit. When it is detected that the leading end of the tag has entered, the tag sending unit stored in the working RAM 84-1 is changed to the denomination-type stacker unit 10a and the tag is sent to the denomination-type stacker unit 10b which is the leading unit in the transport direction.

(FIG. 12-T6) As a result, the unit control section 80-2 of the denomination type stacker section 10b stores the received tag in the working RAM 84-2, and the tag to which its own unit is the destination is attached. By receiving the bill,
Sorting mechanism 63-by driving sorting magnet 63m4
4 is placed on the side of the transport path 60-9, the accumulation monitoring is started, and when the completion of the accumulation is detected by the feeding sensor 13b and the residual sensor 14b, the working RAM is detected.
Delete the tag on 84-2.

(FIG. 11-T7) On the other hand, the unit controller 80-4 of the deposit / withdrawal stacker unit 20 starts feeding the next bill at the time when the first bill has been conveyed to the next unit. There is. Then, when it is detected that the feeding is normally completed as in the case of the first sheet, the tag of the second sheet is generated. The second tag is exactly the same as the first tag except that the serial number is 2.

(FIG. 11-T8) Furthermore, the second tag is set to 1
When the banknotes have been sent to the banknote discriminating section 50 and the banknotes have been conveyed to the next unit as in the case of the first sheet, the third sheet is fed out and processed in the same manner.

(T9 in FIG. 12) Then, when the sending of the third tag and the conveyance to the next unit are completed, the residual sensor 2
4 detects that there are no more banknotes to be paid out, the payout unit is a deposit / withdrawal stacker unit 20, the transport destination is a banknote discrimination unit 50, the serial number is 0, the tag sending unit is a deposit / withdrawal stacker unit 20, and the final banknote flag is A tag that is on is generated in the working RAM 84-4.

Assuming that the result of discrimination of the second bill by the bill discriminating unit 50 is a normal thousand bill, the unit control unit 80-7 of the bill discriminating unit determines the tag conveyance destination on the working RAM 84-7. The denomination type stacker unit 10c and the tag sending unit are changed to the bill discriminating unit 50, and the bill is sent to the denomination type stacker unit 10a and the deposit / withdrawal stacker unit 20 when the leading edge of the bill reaches the next unit.

As a result, the denomination type stacker units 10a, 1
In 0b, since the transfer destination is not the next unit in sequence, the tags and bills are transferred and transferred, and thus the denomination stacker unit 10c
The unit control unit 80-3 starts the stacking monitoring when the next unit receives the bill with the tag as the transfer destination. Then, the delivery sensor 13c and the residual sensor 14
When the completion of integration is detected by c, the working RAM 84
-Delete the tag above 3.

(T10 in FIG. 12) If the bill discriminating circuit 88 determines that the third bill cannot be discriminated, the unit controller 80-7 of the bill discriminating unit 50 has the working RAM.
The transport destination of the tags stored on the 84-7 is temporarily held by the holding unit 3
0, the sending unit is the bill discriminating unit 50, and the sorting magnet 63m2 is driven to set the sorting mechanism 63-2 to the transport path 6
Set to 0-4 side. Then, the tip of the banknote is the temporary holding unit 30.
When the bill position detection sensor 62-5 detects that the tag has entered, the tag is sent to the temporary holding unit 30 and the deposit / withdrawal stacker unit 20.

(FIG. 12-T11) As a result, the unit controller 80-5 of the temporary holding unit 30 sets the tag to the working R.
The data is stored on the AM84-5, and since its own unit is the destination, the accumulation monitoring starts. In addition, the unit control unit 80-4 of the deposit / withdrawal stacker unit 20 generates a bill on the working RAM 84-4 earlier because there is no bill to be dispensed in the unit because the bill dispensed last is discriminated by the bill discriminating unit 50. The stored last bill flag-on tag is sent to the bill validator 50, and the transport motor 61-1 is stopped.

(FIG. 12-T12) Upon receipt of this tag, the unit control unit 80-7 of the bill discriminating unit 50 immediately changes the tag delivery unit to the bill discriminating unit 50 and changes the carrying destination to data indicating all the units. Then, all the leading units in the depositing direction, that is, the temporary holding unit 30 and the money type stacker unit 10a are sent, and the transport motors of the transport paths 60-3 and 60-4 are stopped.

Upon receipt of the final bill flag ON tag, the unit control units 80 of the denomination type stacker units 10a and 10b immediately change the sending unit to their own unit, and there is no bill in the carrying and stacking operation. Transfer to the first unit in the deposit direction and transfer motor 6
1-6, 61-7, 61-8, 61-9 are stopped, respectively.

Upon receipt of this tag, the unit control section 80-3 of the denomination type stacker section 10c has the banknotes accumulated in its own unit. Therefore, the conveyance motor 61-10 is stopped after the accumulation is completed, and Since there is no unit in the depositing direction after the self unit, the operation end message is transferred to the bill depositing / dispensing device control unit 70.

(T13 in FIG. 12) On the other hand, the unit control section 80-5 of the temporary holding section 30 which has received the tag for turning on the last bill flag temporarily stores this tag on the working RAM 84-5 because there are bills being monitored for accumulation. When storing and detecting that the stacking is completed, the conveyance motor 61-5 is stopped, and since there is no unit in the depositing direction after the own unit, the operation end message is transferred to the bill depositing / dispensing device control unit 70.

(FIG. 13-T14) The banknote pay-in / pay-out device control section 70 sends the tags sent and received between the units via the network control circuit 72 from the issuing of the pay-in operation start instruction to the receipt of two operation end messages. If there is no logical failure such as a tag dropout, a notification of deposit completion with data such as the denomination of the deposited bill, the number of bills, and the presence or absence of non-discriminating bills is issued to the host device.

As a result, when the upper-level device sends a return instruction of the non-discrimination ticket to the bill depositing / dispensing device control unit 70, the bill depositing / dispensing device control unit 70 receives it and the temporary depositing unit 30 receives it.
All unit control units 80 except for are instructed to be in the standby state, and subsequently all unit control units 80 are notified that the operation after this instruction is the deposit return operation.

Next, the unit controller 8 of the temporary holding unit 30.
0-5 is instructed that the number of separated sheets is until the banknotes in the unit are exhausted. Next, the bill validator 5
The unit controller 80-7 of 0 is notified that the transfer destination is the deposit / withdrawal stacker 20 regardless of the discrimination result. When the deposit return operation start instruction is issued to all the units, the bill depositing / withdrawing apparatus control unit 70 starts tag monitoring.

(FIG. 13-T15) Subsequent operations are almost the same as the withdrawal operation, and all the banknotes (here, one banknote) in the temporary holding section 30 are conveyed to the deposit / withdrawal stacker section 20 and accumulated. When the operation end message is received from the unit control unit 80-4 of the deposit / withdrawal stacker unit 20, the bill deposit / withdrawal device control unit 70 notifies the upper device of that fact. As a result, when the higher-level device sends a discharge command to the banknote deposit / withdrawal device control unit 70, the banknote deposit / withdrawal device control unit 70 exchanges electronic messages with the deposit / withdrawal stacker unit 20, similarly to withdrawal. The banknote is received by the customer, the upper-level device is notified of the completion of discharging, and all units are instructed to be in the standby state.

<Utilization of Extensibility> In the device having the above-mentioned structure, even if a new function is added, the change of the circuit and the program can be suppressed to the minimum. Here are some examples. <Feed-out Defect Processing> In the depositing / dispensing operation, when a feeding-out failure occurs, a case of adding processing for recovering the entire apparatus without stopping is shown below. Now, when the deposited banknotes are being dispensed from the deposit / withdrawal stacker unit 20 one by one, the unit controller 80 of the deposit / withdrawal stacker unit 20 causes an abnormal skew of the bills dispensed by the dispensing sensor 23.
-4 is detected, the unit control unit 80-4 does not carry the bills other than the relevant bill to the own unit, and therefore the feed motor of the feed mechanism 22 and the feed motor of the feed path 60-1 are stopped urgently.

Abnormal skewing means that bills are fed obliquely,
If the paper is conveyed as it is, it may cause paper jam due to seams between units. The carry motor cannot be stopped instantaneously even if the output of the motor driver circuit 85-4 is turned off, but a sufficient distance is secured from the feeding sensor 23 to the bill position detection sensor 62-1 which is the tip of the unit. If possible, the abnormally skewed banknotes are stopped in the own unit. Therefore, the unit control unit 80-4, when detecting the abnormal skew by the feeding sensor 23, performs the working RAM 84 like normal operation.
No tag is generated at -4.

Then, the conveyance motor is stopped and the conveyance path 6
After the time until 0-1 completely stops, the unit control section 80-4 determines that the transport motor 61 of the transport path 60-1.
The motor driver circuit 85-4 is instructed to drive -1 in the withdrawal direction, that is, in the opposite direction to the slower speed than usual. This is to ensure that the banknotes that are skewed abnormally are stacked in the stacking mechanism 21 of the deposit / withdrawal stacker unit 20.

Then, when the sheets are stacked on the stacking mechanism 21 of the deposit / withdrawal stacker section 20 as in the dispensing operation, the unit controller 80-4 stops the carry motor. After that, the transport path 6
The 0-1 transport motor is driven again in the depositing direction, and when a specified time has elapsed until the specified rotation speed is reached, the unit controller 80-4 restarts the drawing motor, and the drawing mechanism 22 restarts the drawing. By doing this, the skew feeding is corrected and the bill is sent out normally.

During this period, the other unit control section 80 and the bill depositing / dispensing apparatus control section 70 perform only normal operation without being affected by this process. Such an operation is similarly performed in the denomination type stacker units 10a, 10b, 10c and the temporary holding unit 30. Therefore, it is possible to enhance the function of each mechanism section without changing the microprocessors of the control units 70 and 80 and by diverting the programs so far. In addition, the functional upgrade can be modularized without affecting other mechanical divisions.

<Increase in denomination of device> It is assumed that a new denomination other than ten thousand, fifty thousand, and one thousand bills has been issued, for example, fifty thousand bills. In such a case, if a denomination-type stacker unit for 50,000 notes is added and a device having four denomination-type stacker units is recreated, the device of the present invention can be operated simply by making the following changes. It will be possible.

The circuit block is changed only by adding a unit control circuit equivalent to the money type stacker unit 10a shown in the above embodiment. Further, there is no change in the contents of the control program in each unit control unit 80, and the bill deposit / withdrawal device control unit 70 notifies the unit control unit 80 prior to various transaction operations and the added money type. A program for notifying which transaction of the stacker unit requires an operation is changed / added, and the logical check algorithm of the tag monitored during each transaction operation is only changed. Therefore, the expandability is also extremely excellent.

The present invention is not limited to the above embodiments. In the above-mentioned embodiment, the exchange of control information between the control means uses the tag set for each banknote. However,
There are some processing apparatuses that do not necessarily need to perform such control in various types of processing apparatuses for transporting paper sheets. Therefore, the device is divided into a plurality of mechanism sections, the control means provided in the vicinity of each mechanism section are connected through the interface means, and each control means separates its own processing content and processing result from each other. Alternatively, a method of transmitting the notification to the control means, and each control means receiving such a notification and executing a predetermined process may be used. That is, in this case, each control means sends a message to the other control means notifying the processing result or the like not for each sheet but for each constant processing. For example, when a mechanism section notifies that the bill has been fed out, the mechanism section adjacent to the mechanism section recognizes that a certain amount of paper sheets are fed, and performs a certain process on the received paper sheets. Then, it is also possible to perform control such that the processing result is notified to the next mechanism division.

Further, in the above-mentioned embodiment, the upper control device is provided to control the operation of the plurality of mechanism sections. However, the configuration may be such that the start timing of each device is simply controlled or a device for performing communication control is added. In the present invention, the interface means includes not only cables and bus lines that connect the control means provided in each mechanism section, but also equipment and the like for assisting the cooperative operation of these.

Further, if only the transport path of the mechanism section that actually processes the paper sheets among the plurality of mechanism sections is driven, the power consumption can be suppressed most, but this is easy to control. In consideration of the nature, such control may be performed in a plurality of mechanism division units. That is, the mechanism divisions belonging to a certain group may be driven even if the conveyance path is driven for the sake of control, even if the processing of paper sheets is not performed.

[0107]

The paper sheet processing apparatus of the present invention described above is provided with a plurality of mechanism sections for classifying each mechanism for performing a certain processing on the paper sheet on the conveying path according to the processing content, and each mechanism. Each section is provided with a control means for controlling its operation, the control means is arranged in the vicinity of the mechanism section, and the control means are connected through an interface so that each mechanism section operates in cooperation with each other. Therefore, as compared with the case where the entire apparatus is centralized and controlled at a fixed place, the wiring work for connecting to the sensor or the like can be facilitated and the increase in manufacturing cost can be suppressed.

Further, if each of the mechanism sections is controlled independently, it is possible to separately improve each mechanism section in response to the demand for higher functionality and higher performance. A highly versatile and highly flexible device can be realized. Further, if the drive control is independently performed for each mechanical section of the paper sheet, it is possible to stop the conveyance path for the mechanical section that does not need to operate depending on the processing content, and realize power saving. Then, for each sheet, a tag containing control information for processing the sheet is generated, and the control units of the respective mechanism sections transfer the tag to each other to coordinate the processing. For example, it is possible to perform reliable processing without error for each sheet.

Further, when the accumulated paper sheets are taken out and the conveyance abnormality of the paper sheets is detected in the mechanism section, the paper sheets are immediately returned to the accumulation portion to correct the conveyance abnormality, and then the conveyance abnormality is corrected again. If it is taken out, it seems that the conveyance speed is slightly slowed down when seen from other mechanism sections, and does not affect the processing of other mechanism sections at all. Therefore, this kind of abnormality processing can be processed inside each mechanism section, and the management of the device can be facilitated. As a result, it is possible to perform recovery without causing a stop of the device due to a conveyance abnormality or the like, and it is possible to realize an efficient and highly functional device.
