Description

  The present invention relates to a paper sheet handling apparatus that handles paper sheets such as cards, banknotes, and statement slips.

  2. Description of the Related Art Conventionally, a paper sheet handling apparatus that handles paper sheets such as an automatic cash transaction apparatus that is installed in a financial institution and handles banknotes has been provided. This paper sheet handling apparatus is provided with various driving devices in a transport path for transporting paper sheets, a handling port for loading and / or discharging paper sheets, a storage section for storing paper sheets, and the like. ing. This drive device may not be able to operate normally due to wear of parts or sudden changes. When the drive device cannot operate normally in this way, the paper sheet handling device cannot be continued to operate unless a failure occurs and the failure is removed.

  On the other hand, there has been proposed an automatic transaction system that can continue operation by grasping a position where a failure has occurred after the occurrence of the failure and avoiding the position where the failure has occurred (see Patent Document 1). This automatic transaction system is said to be able to reduce the down rate of the automatic transaction apparatus by avoiding the position where the failure occurs.

  However, the automatic transaction system has a problem that an automatic transaction apparatus goes down when a failure occurs at a position that cannot be avoided.

  In addition, the automatic transaction system performs recovery after a failure has occurred, which is inconvenient when the maintenance base is far away, such as overseas. In other words, if the maintenance base is far away, pre-maintenance such as replacing defective parts or worn parts before failure occurs due to periodic maintenance is desirable, but the automatic transaction system is not useful for such pre-maintenance. There wasn't.

From 201, it is possible to re-register new standard transport information and error specific component information via the line control unit 203. Accordingly, the line control unit 203, the standard transport information area 218, and the error specifying component information area 219 function as a registration permission unit.

Next, the process for determining the bill conveyance state will be described by taking a deposit operation and a withdrawal operation as examples.
3A is a configuration diagram showing the configuration of the first sensor 31 and the conveyance path 10, and FIG. 3B is a sensor change time for registering the change times of the sensors 31 to 46 on each conveyance path 10. FIG. 3C is a flowchart illustrating a process of registering the change times of the sensors 31 to 46 on each conveyance path 10 in the sensor change time registration area 212.
FIG. 4 is a flowchart for calculating the conveyance distance and bill length change rate in the conveyance state information area 214 when the conveyance destination is one place.
FIG. 5 is a flowchart for calculating the transport distance and bill length change rate in the transport state information area 214 when the transport destination is sorted by the gate.

  When a bill is set by the customer in the deposit / withdrawal unit 9 (see FIG. 1), the main control unit 202 (see FIG. 2) receives an instruction from the host device 201 via the line control unit 203, and performs a deposit counting operation. To implement.

The main control unit 202 notifies the start of operation to the transport motor control unit 204, the separation motor control unit 207, the stack motor control unit 209, the sensor control unit 211, the transport monitoring control unit 213, and the gate control unit 215. As a result, the transport motor control unit 204 instructs to drive a transport motor (not shown) in the forward direction, rotates the transport path 10 in the forward direction, and registers the motor time in the motor time area 205 as needed.
In addition, the sensor control unit 211 initializes the processing pointer 312 and the storage pointer 311 of each sensor to the head position (step S313).

  Thereafter, the main control unit 202 instructs the separation motor control unit 207 to drive a separation motor (not shown) of the deposit / withdrawal unit 9 (see FIG. 1), and the banknotes 10 from the deposit / withdrawal unit 9 are conveyed one by one. Move out toward.

  The fed banknote is transferred to the transport path 10, passes through the sensors 31 and 32, and is transported to the discrimination unit 2. The discrimination unit 2 determines the authenticity, correctness, denomination, and conveyance state of the banknote.

  The main control unit 202 determines the transport destination of each banknote, such as reject banknotes to the deposit / withdrawal section 9 and normal banknotes to the temporary storage 8. Based on the determined transport destination, the main control unit 202 issues an on / off instruction for the gate 21 to the gate control unit 215 in accordance with the banknote transport order.

In the case of a normal banknote, the normal banknote is passed through the sensors 33 and 34 and temporarily stored in the temporary storage box 8.
In the case of reject banknotes, the reject banknotes are passed through the sensors 33 and 35 and stacked in order behind the partition plate of the deposit / withdrawal unit 9. At that time, the sensor control unit 211 monitors changes in light from dark to dark and light from dark to each sensor, and registers each change time in the sensor change time registration area 212 based on information in the motor time area 205. .

  For example, when the sensor 31 detects a change from light to dark (step S314), the motor time when the light changes from dark to light in the tip time area of the area indicated by the processing pointer 312 (FIG. 3B). The value of the area 205 is registered (step S315), and the process pointer 312 is updated by 1 (step S316).

  Next, when the sensor 31 detects a change from dark to light (step S317), the motor when the change from dark to light occurs in the rear end time area indicated by the storage pointer 311 (FIG. 3B). The value of the time area 205 is registered (step S318), and the storage pointer 311 is updated by 1 (step S319).

  The processes in steps S314 to S319 are performed by passing each banknote until the conveyance of all banknotes is completed (step S320).

  The control in steps S313 to S320 is similarly executed for the sensors 32 to 46 on the transport path 10 during the depositing and storing operation. That is, the change times of the sensors 32 to 46 are registered in the sensor change time registration areas 212 based on the information in the motor time area 205.

  After all the banknotes have been transported to the temporary storage 8 and the deposit / withdrawal unit 9 respectively, the main control unit 202 instructs the transport motor control unit 204 to stop the transport motor and to the transport monitoring control unit 213. To instruct the creation of transport status information. The conveyance monitoring control unit 213 instructed to create conveyance state information creates conveyance state information from the sensor change time registration area 212 and registers it in the conveyance state information area 214.

Next, a method for creating the conveyance state information will be described with reference to the flowcharts of FIGS.
First, the case where the banknotes are not sorted by the gate and transported to one place as in the sensor sections of the sensors 31 to 32 will be described with reference to the flowchart shown in FIG. In this case, the conveyance monitoring control unit 213 uses the information indicated by the processing pointer 312 and the storage pointer 311 from the head information of the sensor change time registration area 212 of each of the sensor 31 and the sensor 32, and uses the conveyance distance and the conveyance status information. The bill length change rate is calculated.

  First, for comparison from the first sheet, N = 1 is set (step S403), the leading edge time of the Nth sensor 31 (the time when the leading edge of the Nth banknote has passed the sensor 31) and the Nth sensor 32. The transport distance of the sensors 31 to 32 (distance to transport the banknote in the sensor section from the sensor 31 to the sensor 32) is calculated from the tip time (step S404).

The conveyance monitoring control unit 213 determines whether or not the calculated conveyance distance is larger than the maximum conveyance distance value of the sensors 31 to 32 already registered in the conveyance state information area 214 (step S405). The Nth transport distance is set in the maximum area (step S406).
In addition, the conveyance monitoring control unit 213 adds the calculated N-th conveyance distance to the sensor 31 to sensor 32 conveyance distance total area at the current conveyance (step S407).

  Next, the conveyance monitoring control unit 213 uses the sensor 31 based on the leading edge time of the N-th sensor 31 and the trailing edge time of the N-th sensor 31 (the time when the trailing edge of the N-th bill passes the sensor 31). The bill length is calculated (step S408). Similarly, the bill length at the sensor 32 is also calculated (step S409).

  The conveyance monitoring control unit 213 calculates a bill length change rate that is a rate at which the bill length has changed in the sensor section from the sensor 31 to the sensor 32 from the calculated N-th sensor 31 and the bill length of the sensor 32. (Step S410). This banknote length change rate is calculated by dividing the banknote length of the sensor 32 at the rear stage by the banknote length of the sensor 31 at the front stage.

  And the conveyance monitoring control part 213 determines whether the calculated banknote length change rate is larger than the banknote length change rate maximum value of the sensors 31-sensor 32 already registered into the conveyance state information area 214 ( Step S411), if larger, the Nth banknote length change rate is set in the banknote length change rate maximum area (step S412).

  Moreover, the conveyance monitoring control unit 213 adds the calculated N-th banknote length change rate to the sensor 31 to sensor 32 banknote length change rate total area at the time of current transport (step S413). This addition is performed by updating the Nth piece of information by 1 until the front end time and the rear end time indicated by the processing pointer 312 and the storage pointer 311 of each of the sensors 31 and 32 (step S414).

  When processing is completed for all the banknotes transported to the sensors 31 to 32 (reach the processing pointer 312 and the storage pointer 311) (step S415), the values of the total transport distance area of the sensors 31 to 32 at the current transport are ( N-1) Divide by the number of sheets, calculate the transport distance average of the sensors 31 to 32 this time, and transport state information only when it is larger than the transport distance average of the sensors 31 to 32 already registered in the transport state information area 214 Registration is made in the transport distance average area of area 214 (step S416). Similarly, the average bill length change rate of the sensors 31 to 32 is also calculated and set (step S417).

Similarly, the transport distance and the bill length change rate are calculated for the sensors 32 to 33 which are transport sections.
In this way, it is possible to calculate the transport distance and bill length change rate for the sensors 32 to 33 in which bills are not sorted by the gate.

  Next, a case where banknotes are sorted by the gate as in the sensors 33 to 34 and the sensors 33 to 35 and conveyed to two places will be described with reference to the flowchart of FIG. In this case, the transport distance and the bill length change rate are calculated by using the information indicated by the processing pointer 312 and the storage pointer 311 from the head information of the sensor change time registration area 212 of each of the sensor 33, the sensor 34, and the sensor 35.

First, the transport monitoring control unit 213 sets N = 1, M = 1, and L = 1 (step S501) for comparison from the first one, and whether the Nth banknote transport destination is the temporary storage 8 side. It is determined whether or not (step S502).
Note that N indicates the total number of banknotes to be conveyed, and M and L indicate the number of banknotes that pass through the corresponding sensors. In this embodiment, M indicates the number of banknotes passing through the sensor 34, and L indicates the number of banknotes passing through the sensor 35.
On the temporary storage 8 side, the transport distance of the sensors 33 to 34 is calculated from the leading edge time of the Nth sensor 33 and the leading edge time of the Mth sensor 34 (step S503).

The conveyance monitoring control unit 213 determines whether or not the calculated conveyance distance of the Mth sheet is larger than the maximum conveyance distance value of the sensors 33 to 34 already registered in the conveyance state information area 214 (step S504). In this case, the M-th transport distance is set in the maximum transport distance area (step S505).
Further, the transport monitoring control unit 213 adds the calculated transport distance of the Mth sheet to the total transport distance area of the sensor 33 to the sensor 34 at the current transport (step S506).

  Next, the conveyance monitoring control unit 213 calculates the bill length at the sensor 33 based on the leading edge time of the Nth sensor 33 and the trailing edge time of the Nth sensor 33 (step S507). Similarly, the conveyance monitoring control unit 213 calculates the length of the Mth banknote at the sensor 34 (step S508).

  The conveyance monitoring control unit 213 calculates the M-th bill length change rate from the calculated bill lengths of the N-th sensor 33 and the M-th sensor 34 (step S509), and has already entered the conveyance state information area 214. It is determined whether or not it is larger than the maximum bill length change rate of the registered sensors 33 to 34 (step S510). If it is larger, the Mth bill length change rate is displayed in the maximum bill length change rate area. Set (step S511).

  Moreover, the conveyance monitoring control part 213 adds the calculated M-th banknote length change rate to the sensor 33-sensor 34 banknote length change rate total area at the time of this conveyance (step S512). In this addition, when the transport destination is the temporary storage 8 side, the M-th piece information is updated by 1 until the front end time and the rear end time indicated by the processing pointer 312 and the storage pointer 311 of the sensor 34 (step S513). In addition, the Nth piece of information is updated by 1 (step S524) and executed.

  In step S502, when the transport destination is not the temporary storage 8 side but the deposit / withdrawal unit 9 side, the transport monitoring control unit 213 detects the leading edge time of the Nth sensor 33 and the leading edge time of the Lth sensor 35. 33-sensor 35 transport distance is calculated (step S514).

  The conveyance monitoring control unit 213 determines whether or not the calculated conveyance distance of the Lth sheet is larger than the maximum conveyance distance value of the sensors 33 to 35 already registered in the conveyance state information area 214 (step S515). In this case, the L-th transport distance is set in the maximum transport distance area (step S516). Further, the transport monitoring control unit 213 adds the calculated transport distance of the Lth sheet to the total transport distance area of the sensor 33 to the sensor 35 during the current transport (step S517).

  Next, the conveyance monitoring control unit 213 calculates the bill length at the sensor 33 from the leading edge time of the Nth sensor 33 and the trailing edge time of the Nth sensor 33 (step S518). Similarly, the length of the Lth banknote in the sensor 35 is also calculated (step S519).

  The conveyance monitoring control unit 213 calculates the change rate of the L-th bill length from the calculated bill lengths of the N-th sensor 33 and the L-th sensor 35 (step S520), and has already entered the conveyance status information area 214. It is determined whether or not it is larger than the maximum bill length change rate of the registered sensors 33 to 35 (step S521). If it is larger, the Lth bill length change rate is set in the maximum bill length change area. Set (step S522).

  Further, the transport monitoring control unit 213 adds the calculated L-th banknote length change rate to the sensor 33 to sensor 35 banknote length change rate total area during the current transport (step S522). In this addition, when the transport destination is the deposit / withdrawal unit 9 side, the L-th piece information is updated by 1 until the front end time and the rear end time indicated by the processing pointer 312 and the storage pointer 311 of the sensor 35 (step S523), In addition, the Nth piece of information is updated by 1 (step S524) and executed.

  The conveyance monitoring control unit 213 completes the processing for all banknotes conveyed to the sensors 33 to 34 and the sensors 33 to 35 (reach each processing pointer 312 and the storage pointer 311) (step S526), and this time conveyance is performed. Then, the value of the total transport distance area of the sensors 31 to 32 is divided by (N−1) sheets to calculate the average transport distance of the sensors 33 to 34 and the sensors 33 to 35 this time. Compared with the respective transport distance averages of the sensors 33 to 34 and the sensors 33 to 35 registered in (1), only when the average is larger, it is registered in the transport distance average area of the transport state information area 214 (step S527). Similarly, the conveyance monitoring control unit 213 calculates and sets the average bill length change rate of the sensors 33 to 34 and the sensors 33 to 35 (step S527).

  After completing the creation of the conveyance state information, the main control unit 202 notifies the host device 201 of the completion of the depositing count via the line control unit 203.

  Thereafter, when the host apparatus 201 is instructed to receive and store money via the line control unit 203, the main control unit 202 instructs the transport motor control unit 204 to drive a transport motor (not shown) in the reverse direction. The banknotes temporarily stored in the temporary storage 8 are fed one by one and stacked in the banknote boxes 3, 4, 5 or 6 and the reject box 7 according to the result of the discrimination unit 2.

  At that time, the sensor sections of sensor 34 to sensor 33, sensor 33 to sensor 32, sensor 32 to sensor 31, sensor 31 to sensor 36, sensor 36 to sensor 37, sensor 41 to sensor 42 are shown in FIG. Similarly to the sensor sections of the sensors 31 to 32, the transport distance and the bill length change rate are calculated based on the change time of each sensor.

  Further, the sensor 37 to the sensor 38, the sensor 37 to the sensor 46, the sensor 38 to the sensor 39, the sensor 38 to the sensor 45, the sensor 39 to the sensor 40, the sensor 39 to the sensor 44, the sensor 40 to the sensor 41, and the sensor 40 to the sensor 43. For each sensor section, the transport distance and the bill length change rate are calculated in the same manner as the sensor sections of the sensors 33 to 34 and the sensors 33 to 35 shown in FIG.

  After completing the creation of the conveyance state information in this way, the main control unit 202 notifies the host apparatus 201 of the completion of deposit storage via the line control unit 203.

  The withdrawal operation is performed by the main control unit 202 that has received a withdrawal instruction from the host device 201 via the line control unit 203. The main control unit 202, which is instructed to withdraw money, starts operation to the transport motor control unit 204, the separation motor control unit 207, the stack motor control unit 209, the sensor control unit 211, the transport monitoring control unit 213, and the gate control unit 215. contact.

In addition, the sensor control unit 211 initializes the processing pointer 312 and the storage pointer 311 of each sensor to the head position.

  Thereafter, the main control unit 202 instructs the separation motor control unit 207 to drive a separation motor (not shown) of the banknote box 3, 4, 5 or 6 in which the denomination is stored, one by one. A bill is fed out from a bill box in which seeds are stored. Here, the case where it is fed out from the banknote box 3 will be described as an example.

  The fed banknote is transferred to the conveyance path 10, passes through the sensors 41, 40, 39, 38, 37, 36, 31, 32 and is conveyed to the discrimination unit 2. The discrimination unit 2 determines the authenticity, correctness, denomination, and conveyance state of the bills that have been conveyed.

  The main control unit 202 determines each transport destination, such as reject banknotes to the temporary storage 8 and normal banknotes to the deposit / withdrawal unit 9. Based on the determined transport destination, the main control unit 202 issues an on / off instruction for the gate 21 to the gate control unit 215 in accordance with the banknote transport order. In the case of a normal bill, the normal bill is passed through the sensors 33 and 35 and stacked in order on the deposit / withdrawal unit 9. In the case of a reject banknote, the reject banknote is passed through the sensors 33 and 34 and temporarily stored in the temporary storage 8.

  The main control unit 202 stacks all banknotes fed out from the banknote box 3 in the deposit / withdrawal unit 9 and the temporary storage unit 8 according to the discrimination of the discrimination unit 2, respectively, and then the transport motor control unit 204 is controlled by the transport motor. Stop driving.

  And based on the change time of each sensor, sensor 41-sensor 40, sensor 40-sensor 39, sensor 39-sensor 38, sensor 38-sensor 37, sensor 37-sensor 36, sensor 36-sensor 31, sensor 31- About each sensor area of the sensor 32 and the sensor 32-the sensor 33, a conveyance distance and a banknote length change rate are calculated similarly to each sensor area of the sensor 31-the sensor 32 shown in FIG.

It is calculated according to the section, an allowable value is determined, and it is registered in the standard transport information area 218 from the host device 201 via the line control unit 203.

  Similarly, component information and a coping method for which a failure is predicted are determined for each error occurrence prediction sensor section, and are registered in the error specifying component information area 219 from the host device 201 via the line control unit 203.

  In the standard transport information area 218, the Mahalanobis distance based on the maximum, minimum, average, and standard deviation is calculated based on any information of banknote shift, skew, banknote interval, transport distance, and length change rate. It is preferable to obtain a unit space by the MT method based on the calculated Mahalanobis distance and register this unit space.

Next, standard conveyance information used for predicting the occurrence of a failure and error-specific component information that is component information about a component that is predicted to be defective will be described.
6, 7, 8, and 9 are examples of the standard conveyance information area 218 registered in advance at the time of shipment.
In the case of deposit counting, as shown in FIG. 6, the permissible maximum value and permissible average value for the transport distance and the permissible maximum value and permissible average value for the bill length average rate are related to the standard transport information area 218. Stored for each sensor section.

  In the case of deposit storage, as shown in FIG. 7, the standard conveyance information area 218 is associated with an allowable maximum value and an allowable average value for the transfer distance, and an allowable maximum value and an allowable average value for the bill length average rate. Stored for each sensor section.

  In the case of withdrawal, as shown in FIG. 8, the permissible maximum value and permissible average value for the transport distance and the permissible maximum value and permissible average value for the bill length average rate are related to the standard transport information area 218. Stored for each sensor section.

  As shown in FIG. 9, in the case of withdrawal / rejection storage, in the standard transport information area 218, the permissible maximum value and permissible average value for the transport distance and the permissible maximum value and permissible average value for the bill length average rate are set. It is stored for each related sensor section.

  FIG. 10 shows an example of the error specific component information area 219 registered in advance at the time of shipment.

  The error specific component information area 219 stores component information of a component that is predicted to fail and a coping method for each error occurrence prediction section. In each error occurrence prediction section, a plurality of pieces of component information are stored, and a coping method is stored for each piece of component information.

Next, an operation for outputting a failure prediction will be described.
FIG. 11 is a flowchart showing an operation of outputting a failure prediction.
12 and 13 are pre-error prediction screens that are one of the maintenance screens displayed on the display device by the operation of the staff.

  When an input means such as a key switch is input during a regular inspection by an attendant and the bill processing apparatus 1 is switched to the inspection mode (step S601), the main control unit 202 as a control means 218 is compared with the transport state information area 214, and failure prediction is performed (step S602). In this failure prediction, the main control unit 202 predicts a failure in the transport section (sensor section) when the value in the transport state information area 214 is more than a certain value compared to the value in the standard transport information area 218. It is set as the conveyance section to be performed.

  Note that it is preferable to determine whether or not there is a fluctuation of a certain value or more by calculating a Mahalanobis distance with respect to a conveyance distance or a bill length change rate and whether or not the Mahalanobis distance is within the unit space described above.

  In the failure prediction, when the value of the conveyance state information area 214 has fluctuated by a certain value or more compared to the value of the standard conveyance information area 218 (step S603), the main control unit 202 displays as output means (not shown). As shown in FIG. 12, a maintenance screen 701 including failure occurrence prediction section information as failure prediction information is displayed on the apparatus (step S604). This maintenance screen 701 includes a treatment display section 702 as part information, a “next error occurrence prediction section display” button 703, a “detailed information display of this section” button 704, a “maintenance screen end” button 705, and a fault portion. A display diagram 706 is provided.

  The treatment display unit 702 is a color (for example, a conspicuous color such as red) that is different from other components in a component (a specific part of the conveyance path 10, a specific sensor among the identification units 2 and 31 to 46) from which a failure is predicted Lights up. As a result, an attendant is made to recognize parts that are likely to cause various abnormalities such as roller wear, foreign matter contamination, belt catching, etc., that is, parts that are likely to cause faults, that is, parts that are predicted to have faults. .

  When the clerk presses the “detailed information display for this section” button 704 on the predicted failure occurrence section display screen (step S605), the main control unit 202 displays the detailed information display screen on the display device as shown in FIG. The maximum value and the average value of the failure occurrence prediction section are displayed (step S606). As a result, the staff can check the conveyance state in the failure occurrence prediction section.

  The failure occurrence section information and the failure occurrence section detailed information can be printed by a printing unit. Also, the standard transport information area 218 can be reviewed by collecting information on each device and statistically investigating the transport status of the failure prediction section. If the standard transport information area 218 needs to be changed based on the result of the investigation, the standard transport information area 218 is changed within a certain value in the specific transport section until the standard transport information area 218 is changed from the host device 201 via the line control unit 203. It is also possible to prevent maintenance by the staff for fluctuations (preventing unnecessary maintenance due to variations in banknote factors, environment, etc.).

  If the fluctuation is within a certain value in all the transport sections in step S603, “Normal” is displayed on the screen (step S607), and the person in charge is notified.

  With the above operation, the conveyance state by each sensor can be monitored and the change in the conveyance state can be recorded. This change in the conveyance state is due to various causes such as roller wear and gate abnormality. By measuring the conveyance distance of the banknote and comparing it with the normal conveyance distance, the conveyance delay and skew of the banknote It is possible to grasp the change in the conveyance state due to the above. Then, it is possible to identify a transport section where a failure is predicted from the change in the transport state, and to contact a staff member who regularly checks the transport section. Personnel can take measures such as replacement of consumables based on failure prediction information displayed during periodic inspections, etc., and eliminate failures before they occur to reduce equipment downtime due to failures Can do.

  In particular, by calculating the bill length based on the leading edge passage time and the trailing edge passage time of each bill for each of the sensors 31 to 46, it is possible to determine that the bill is skew if the bill length is longer than normal. It is possible to make an attendant recognize that there is an abnormality that may cause a failure in the future in the sensor section leading to the sensor.

  Moreover, about the sensor area between adjacent sensors, the conveyance distance of the banknote of the said sensor area is calculated | required by the passage time (in this embodiment front end passage time) when the banknote passed the adjacent sensor in order. In order to determine whether or not the distance is appropriate, it is possible to make an attendant recognize that an abnormality that may cause a failure in the future exists in this sensor section.

In addition, since the failure prediction information is displayed, the attendant can confirm the failure prediction information and remove the cause of the failure before the failure actually occurs.
In addition, when calculating based on the Mahalanobis distance, it is possible to predict a failure with higher accuracy.

  In addition, since the sensor section and the part in which the failure is predicted to occur in the sensor section are associated with each other and stored in the error specifying part information area 219, the registration is permitted and can be updated. It is possible to appropriately cope with version 1 upgrades and software updates.

  In addition, since the failure prediction information is displayed only at the time of an operation such as periodic inspection by a staff member, the failure prediction information is not displayed when the general user uses it, and the general user can feel at ease in the automatic transaction apparatus 1. Transaction processing can be executed.

  Moreover, in banknote conveyance information, it is also possible to perform more accurate abnormality prediction by excluding registration of banknote information when a jam occurs due to a specific banknote or the like. Further, by applying such information to each unit such as a gate state, separation, and stack state, it is possible to expand the prediction of failure occurrence. As a result, it is possible to encourage the staff to check and perform preliminary maintenance, and to reduce the apparatus down due to the occurrence of a failure.

  Moreover, not only failure prediction but also stop and error notification when a failure actually occurs can be performed without any problem. In other words, if a change over a certain period of time cannot be detected by monitoring the sensors 31 to 46, the main control unit 202 determines that a failure has occurred due to a jam or the like, passes a feed stop command to the separation motor control unit 207, and controls the conveyance motor. A conveyance stop command is passed to the unit 204. Then, error information is transmitted to the host device 201 via the line control unit 203.

  The fixed time for determining that a failure has occurred is set longer than the time corresponding to the maximum allowable value at the transport distance and the time corresponding to the maximum allowable value of the bill length change rate. And the detection of the actual failure can coexist.

  In addition, this invention is not limited only to the structure of the above-mentioned embodiment, Many embodiments can be obtained.
