Description

  The present invention relates to a paper sheet storage device that stores and feeds paper sheets such as banknotes.

  A banknote storage cassette as a paper money storage device of a denomination mounted on a banknote depositing and dispensing machine of a conventional automatic teller machine is a stage configured to be movable up and down to stack and stack banknotes in the thickness direction. , The transported banknotes are collected on the stage, the stored banknotes are separated and fed one by one, an optical end detector for detecting “no banknotes”, and “small amount of banknotes” When the near-end detector detects that the amount of stored bills is less than a predetermined amount, the near-end detector is equipped with an optical near-end detector that detects the amount of bills. The monitoring device sends an alarm to the maintenance center's monitoring device, the monitoring device loads banknotes in the batch storage, notifies the maintenance personnel of the transport of the batch storage, and the maintenance staff sends the batch storage to the sender. Transport to an automated teller machine Wear and are supplemented with bills in the banknote storage cassette (e.g., see Patent Document 1.).

JP 2005-182348 A (paragraphs 0011, 0018-0021, FIG. 5)

  However, in the conventional technology described above, the bill storage amount is detected by the full detector, the near end detector, and the ON / OFF state of the end detector, and these optical detectors are operated during normal operation. Since the ON / OFF state is not switched, there is a problem that a failure of the detector cannot be found.

  That is, since the near-end detector and the end detector continue to detect bills or stages (referred to as objects) that are normally stored, they are in the ON state (the light receiving element is not receiving light from the light emitting element). That is, it is a dark state.) Since the full detector does not detect the object, it is in the OFF state (the light receiving element is receiving light from the light emitting element, that is, the bright state). It has become.

  For this reason, for example, when the light emitting element of the near-end detector does not emit light due to life, disconnection, dirt, etc. or when the amount of light decreases, or when light from the light emitting element cannot be received due to dirt on the light receiving element, etc. Even when it occurs, it is indistinguishable from the normal state (near end detector, end detector ON state (dark), full detector OFF state (bright)), and no near end is detected. When the end is detected suddenly, the automatic teller machine stops withdrawing money from the bill storage cassette (see, for example, paragraphs 0061-0063 of JP-A-2001-236548), and customer convenience is reduced. At the same time, in the technique disclosed in Patent Document 1, replenishment of banknotes cannot be made in time, and there arises a problem that the withdrawal of banknotes of the denomination is stopped until the replenishment is completed.

  In addition, even if the end detector fails, it is indistinguishable from the normal state in the normal case, and the end is not detected after the near end is detected, so that a situation in which banknotes cannot be drawn out during the withdrawal transaction occurs. There is a problem that the denomination cannot be withdrawn and a complaint is received from the customer.

  Furthermore, even if the full detector changes from the OFF state (bright) to the ON state (dark) due to a failure, the normal state is full (the near-end detector, end detector, and full detector are all in the ON state). There is a problem that the transaction of the denomination is stopped due to misjudgment, and the convenience of the customer is lowered.

  In addition to the above failure, if the circuit configuration is such that the LO signal is output when the light receiving element is in the OFF state (bright), the OFF state continues to be output when the signal line from the light receiving element is disconnected. Therefore, for example, when such a failure occurs in the full detector, a normal state in a normal state (near end detector, end detector is ON state (dark), full detector is OFF state (bright)). Can not be distinguished, even if the bill storage cassette is full, it is misjudged that it is not full, jamming occurs as a result of excessive bills that cannot be stacked, and the device stops and deposit transactions can be executed The problem of receiving complaints from customers occurs.

  Even if a problem due to a failure of the detector as described above occurs, the maintenance staff in charge of replenishing banknotes has a small replenishment amount to the banknote storage cassette to be replenished or the weight of the replaced banknote storage cassette. As a result, a misjudgment due to a failure of the position detection sensor will be found locally, and the banknotes in the banknote storage cassette will be wasted due to erroneous detection, and the efficient operation of replacement of the banknote storage cassette will be difficult. The problem arises.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide means for determining a failure of a sensor that detects a storage amount of paper sheets such as banknotes.

  In order to solve the above-described problems, the present invention provides a stage configured to be movable up and down that stacks and stacks paper sheets in the thickness direction, and a plurality of position detections that detect the presence of a light shielding plate provided on the stage. In a paper sheet storage device that includes a sensor and an encoder that detects the amount of movement of the stage, and stores and feeds paper sheets, the position detection sensor is moved along the stage movement direction that is the movement direction of the stage. It is arranged in a line, and a failure of the position detection sensor is determined by a logical contradiction in the detection of the light shielding plate by the position detection sensor.

  Thereby, the present invention has an effect that it is possible to easily determine the failure of the position detection sensor that detects the storage amount of the paper sheet.

A delivery monitoring sensor 4a which is an optical sensor is provided.

  Reference numeral 6 denotes a gate roller, which is disposed below the feed roller 3 and includes a one-way rotation mechanism that rotates together with the feed roller 3 when the banknotes S are collected around the gate roller shaft 6a, but does not rotate when the bill is fed out. It has a function of separating the banknotes S fed out from the banknote storage cassette 1 one by one.

  A pickup roller 7 is provided on the upstream side of the feeding direction of the banknote S (referred to as a banknote feeding direction) of the feed roller 3, and is a support lever (not shown) whose one end is rotatably supported by the feed roller shaft 3 a. It is attached to the feed roller 3 so as to be able to rotate forward and backward around a pickup roller shaft 7 a provided at the movable end, and rotates in the same direction in conjunction with the feed roller 3.

  Further, the support lever is biased toward the stage 12 described later by a spring member (not shown), and the pickup roller 7 presses the uppermost banknote S on the stage 12 with a predetermined pressing force at the movable end. A pressure detection sensor 8 is provided for detecting the above.

  9 is a tongue piece roller, which is a roller in which a plurality of tongue pieces 10 made of a flexible thin plate member made of an elastic material such as synthetic rubber are radially provided on the outer peripheral surface of the hub portion. 3 has a function of pushing the rear end of the banknote S released from 3 at the front end of the tongue piece 10 rotating around the tongue piece roller shaft 9a, knocking it down, and pulling it up and accumulating it on the stage 12 described later, The retracting mechanism 11 including an actuator, a link mechanism, and the like does not interfere with the stacking position (see FIG. 1) in which the gate roller shaft 6a and the tongue roller shaft 9a are coaxial, and the conveyance of the bill S fed by the feed roller 3. It is configured to move between the retracted positions (see FIG. 3).

  The separating and accumulating mechanism 2 according to this embodiment includes a feed roller 3, a gate roller 6, a pickup roller 7, a tongue piece roller 9, and the like.

  The stage 12 is a plate-like member that stacks and stacks the banknotes S discharged between the feed roller 3 and the gate roller 6 rotating in the stacking direction on the upper surface 12a in the thickness direction. It can be moved up and down by an elevating mechanism using as a drive source.

  Further, the stage motor 13 of the lifting mechanism has a built-in encoder 14 so that the amount of rotation of the shaft of the stage motor 13 can be detected. The shaft of the stage motor 13 is directly connected to the stage 12 via an elevating mechanism, and the amount of movement of the stage 12 can be calculated from the amount of rotation of the stage motor 13 detected by the encoder 14.

  Reference numeral 15 denotes a position detection sensor, which is an optical sensor having a U-shaped main body in which a groove 17 through which the light shielding plate 16 passes is formed, and a light emitting portion 18a provided on each side surface of the groove 17 respectively. And the light receiving unit 18b are arranged so as to face each other, and the light receiving unit 18b detects that the light from the light emitting unit 18a is blocked by the light blocking plate 16 to detect the presence of the light blocking plate 16.

  The light shielding plate 16 is a plate-like member attached to one end of the stage 12 and moves together with the stage 12. The upper end of the light shielding plate 16 coincides with the upper surface 12a of the stage 12, and is a portion that shields light from the light emitting portion 18a. The length of the stage 12 in the stage moving direction (vertical direction in FIG. 1 and referred to as the stage moving direction) is formed as L1 (this length L1 is referred to as the light shielding plate length L1).

  In the banknote storage cassette 1 of the present embodiment, a storage space 19 (a space indicated by a broken line in FIG. 1) is set as a space in which the banknote S can be stored, and the upper surface 19 a raises the stage 12. Then, the pickup roller 7 is pushed up by the uppermost banknote S of the stacked banknotes stacked thereon, and the position where the press detection sensor 8 of the pickup roller 7 detects the movable end of the support lever (referred to as banknote press position). The lower surface 19b of the stage 12 is set to the position of the upper surface 12a of the stage 12 when the stacked banknotes stacked on the stage 12 are full.

  In addition, a stacking operation space 20 is set at the top of the storage space 19 as a space required for the stacking operation of the bills S, the upper surface thereof is set to the upper surface 19a (banknote pressing position) of the storage space 19, and the lower surface is the stage 12. When the banknotes S are stacked on the uppermost banknote S of the stacked banknotes stacked above, the rear end of the banknotes S stacked at the front end of the tongue piece 10 of the tongue piece roller 9 can be drawn. The length of the accumulation operation space 20 in the stage moving direction is set to L2 (this length L2 is referred to as the accumulation operation space length L2).

  The position detection sensor 15 of the present embodiment includes a total of five position detection sensors 15, 15 a and 15 b at the upper part outside the storage space 19, and three lines 15 c to 15 e at the lower part in one row along the stage moving direction. The distance between the centers of the optical axes of the adjacent light emitting portions 18a is set to be longer than the light shielding plate length L1.

  Therefore, in the normal state of each position detection sensor 15, when the light shielding plate 16 exists between the position detection sensors 15, all the position detection sensors 15 are in the OFF state (the light receiving unit 18b receives light from the light emitting unit 18a). When the position detection sensor 15 detects the presence of the light shielding plate 16, only the position detection sensor 15 is in the ON state (light receiving unit). 18b is a state where the light from the light emitting portion 18a is not received, that is, a dark state.), And the other position detection sensors 15 are in an OFF state.

In FIG. 2, reference numeral 21 denotes a control unit of the banknote storage cassette 1, which controls each part in the banknote storage cassette 1 according to a command from a banknote depositing / dispensing machine as a host device, and stacking processing, feeding processing, and position of the banknote S It has a function of executing various processes such as a failure determination process of the detection sensor 15.
A storage unit 22 of the banknote storage cassette 1 stores a program executed by the control unit 21, various data used for the program, a processing result by the control unit 21, and the like.

  The storage unit 22 of the present embodiment has an application program having a function of executing processing for stacking and feeding banknotes S described below, failure determination processing for the position detection sensor 15, processing for confirming the number of stacked sheets and the number of stacked sheets, and the like. A cassette processing program including an application program having a function of detecting opening / closing of a cassette door (not shown) and recording the opening / closing time and the number of stored sheets at that time is stored in advance, and the cassette executed by the control unit 21 Each functional means of the bill storage cassette 1 of this embodiment is formed by the steps of the processing program.

  The storage unit 22 stores a position of the upper surface 12a of the stage 12 from the lower surface 19b of the storage space 19 (referred to as a stage position Lp) based on the waveform count output from the encoder 14. A position storage area and a storage number count area for counting the number of stored banknotes S stored in the banknote storage cassette 1 by an output signal from the delivery monitoring sensor 4a are secured in advance.

  Further, the storage unit 22 includes the light shielding plate length L1, the integrated operation space length L2, and the center of the optical axis of the light emitting unit 18a of each of the position detection sensors 15a to 15e and the lower surface 19b of the storage space 19. The sensor positions La to Le (refer to FIG. 1) as distances, the storage length L3 (refer to FIG. 1) as the distance between the lower surface 19b and the upper surface 19a of the storage space, and the count by the encoder 14 built in the stage motor 13 The conversion coefficient when converting the number into the amount of movement of the stage 12, the thickness setting value Th which is the setting value of the thickness of the banknote S handled by the banknote storage cassette 1, the number of storages counted by the delivery monitoring sensor 4a and the confirmation described later A predetermined permissible range (in this embodiment, a range of 95% or more and 105% or less of the number of stored sheets) for determining that the difference from the number of stacked sheets on the stage 12 calculated by the processing is a difference is preset and stored. It has been.

  The control unit 21 of the banknote storage cassette 1 according to the present embodiment counts the output from the encoder 14 of the stage motor 13 of the lifting mechanism when the stage 12 is moved up and down in the stacking process and feeding process described later, and the count value. Is converted into the movement amount of the stage 12 using the conversion coefficient stored in the storage unit 22, and the converted movement amount is added to the stage position Lp stored in the stage position storage area of the storage unit 22, or the stage The stage position Lp is managed while updating the stage position Lp from the lower surface 19b of the storage space 19 to the upper surface 12a of the stage 12 by subtracting from the position Lp.

  Then, the control unit 21 detects when any of the position detection sensors 15 changes from the ON state to the OFF state, or from the OFF state to the ON state as the stage 12 moves up and down, that is, any of the position detection sensors 15 corresponds to the stage 12. When the presence of the light shielding plate 16 provided at the position is detected, the position detection sensor 15 detecting the light shielding plate 16 becomes a new reference based on the sensor position stored in the storage unit 22 and the stage moving direction. The stage position Lp is calculated, and the stage position Lp stored in the stage position storage area is rewritten to the calculated stage position Lp and reset.

  For example, when the position detection sensor 15c changes from the ON state to the OFF state during its rise, as in the stage 12 indicated by a two-dot chain line in FIG. 3, the change is due to the lower end of the light shielding plate 16. The position of the upper surface 12a of the stage 12 (stage position Lp) is calculated by adding the light shielding plate length L1 to the sensor position Lc, and the stage position Lp in the stage position storage area is set to the calculated stage position Lp as a new reference. Rewrite and reset.

  Further, when the position detection sensor 15c changes from the OFF state to the ON state while the stage 12 is moving up, the change is due to the upper end of the light shielding plate 16, that is, the upper surface 12a of the stage 12, and therefore the sensor position Lc. Is calculated as the position of the upper surface 12a of the stage 12, and the stage position Lp in the stage position storage area is rewritten and reset to the calculated stage position Lp as a new reference.

  When the position detection sensor 15c changes from the ON state to the OFF state while the stage 12 is descending, the change is due to the upper end of the light shielding plate 16 (the upper surface 12a of the stage 12). 12 is calculated as the position of the upper surface 12a of the stage 12, and the stage position Lp in the stage position storage area is rewritten to the calculated stage position Lp as a new reference and reset.

  Further, when the position detection sensor 15c changes from the OFF state to the ON state while the stage 12 is descending, the change is due to the lower end of the light shielding plate 16, so the light shielding plate length L1 is set to the sensor position Lc. In addition, the position of the upper surface 12a of the stage 12 is calculated, and the stage position Lp in the stage position storage area is rewritten and reset to the calculated stage position Lp that becomes a new reference.

Thus, in this embodiment, when any one of the position detection sensors 15 detects the light shielding plate 16 while the stage 12 is moving up and down, the stage position Lp in the stage position storage area is known in consideration of the stage moving direction. Therefore, the stage position Lp can be accurately managed while eliminating the accumulated error of the movement amount accompanying the elevation of the stage 12 detected by the encoder 14.
While managing the stage position Lp as described above, the control unit 21 executes the stacking process and the feeding process of the banknotes S.

Below, the collection process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
When receiving a stacking instruction associated with a deposit transaction selected by the customer from the banknote depositing / dispensing machine, the control unit 21 of the banknote storage cassette 1 sets each part of the banknote storage cassette 1 in a waiting state for stacking.

  That is, when the pressing detection sensor 8 of the pickup roller 7 detects the movable end of a support lever (not shown), the control unit 21 retracts the tongue roller 9 by the retracting mechanism 11 when it is not in the ON state. The position is retracted (see FIG. 3), the stage motor 13 of the lifting mechanism is rotated to raise the stage 12, and the position where the pressure detection sensor 8 is turned on, that is, the highest level of the stacked banknotes stacked on the stage 12 Is moved to a position (banknote pressing position) where the upper surface of the banknote S coincides with the upper surface of the storage space 19. In addition, when the press detection sensor 8 is in the ON state when receiving a command from the banknote depositing / dispensing machine, that is, when the upper surface of the uppermost banknote S is already in the banknote pressing position, the above operation is omitted. Is done.

  The control unit 21 that has recognized that the uppermost banknote S is in the banknote pressing position is separate from the count for managing the stage position Lp described above, and the encoder 14 of the stage motor 13 from the banknote pressing position in the storage unit 22. The stage 12 is lowered while counting the output of, and the amount of movement of the stage 12 converted from the counted number using the conversion coefficient of the storage unit 22 reaches the integrated operation space length L2 stored in the storage unit 22. Sometimes the stage 12 is stopped, the stacking operation space 20 required for the stacking operation of the bills S is secured, and the tongue piece roller 9 is moved from the retracted position to the stacking position (see FIG. 1). Note that the tongue roller 9 may be moved by parallel processing while the accumulation operation space 20 is secured.

When the stacking operation space 20 is secured, the control unit 21 executes a confirmation process of a stacking surplus number that is the number of banknotes S that can be further stacked on the stage 12 at the start of the stacking operation.
That is, the control unit 21 reads the stage position Lp stored in the stage position storage area of the storage unit 22 and reads the thickness setting value Th of the banknote S stored in the storage unit 22, The stage position Lp, which is the distance between the lower surface 19b and the upper surface 12a of the stage 12, is divided by the thickness setting value Th to calculate the number of accumulation margins at the start of the accumulation operation.

And the control part 21 transmits the calculated accumulation | storage margin number to the monitoring apparatus of the monitoring center which is not shown in figure monitoring the some banknote depositing / withdrawing machine via a banknote depositing / withdrawing machine.
The control unit 21 that has transmitted the calculated stacking surplus number rotates the feed roller 3 and the pickup roller 7 in the stacking direction and rotates the pinch roller 5 and the tongue piece roller 9 in the opposite direction to finish preparation for receiving the bill S. , And waits for the bill S to be carried in from the delivery port 4.

When the banknote S is carried in from the delivery port 4, the banknote S is detected by the delivery monitoring sensor 4 a, and then sandwiched between the feed roller 3 and the pinch roller 5, and is accumulated by the feed roller 3 along the guide (not shown). (See FIG. 1), and the rear end of the released banknote S is pushed by the tip of the tongue piece 10 of the tongue piece roller 9, knocked down, and drawn to be collected on the stage 12. Accumulated on the banknote P.
By repeating such a stacking operation, the bills S are continuously stacked on the stage 12.

  During this stacking operation, every time the delivery monitoring sensor 4a detects a new banknote S, the control unit 21 adds “1” to the count number of the stored number count area of the storage unit 22 and counts the stored number. At the same time, the thickness setting value Th stored in the storage unit 22 is used to calculate a decrease in the stacking operation space length L2 due to the stacked banknotes S, and the decrease is converted into the amount of rotation of the encoder 14. The stacking operation space 20 is always controlled while lowering the stage 12 according to the number of stacked bills S.

  When the stacking of the bills S according to the current stacking command is finished, the control unit 21 stops the separation and stacking mechanism 2 and causes the tongue roller 9 to retract to the retracted position by the retracting mechanism 11 in order not to make the stacked bills free. Then, the stage motor 13 is rotated to raise the stage 12 until the pressure detection sensor 8 of the pickup roller 7 is turned on, and the stacked banknotes are sandwiched between the stage 12 and the pickup roller 7 to remove the uppermost banknote S. It is located at the bill pressing position.

The control unit 21 that has recognized that the stacked banknotes are sandwiched between the stage 12 and the pickup roller 7 executes a confirmation process of the number of stacked sheets at the end of stacking.
That is, the control unit 21 reads out the stage position Lp when the stacked banknotes on the stage 12 are sandwiched between the stage 12 and the pickup roller 7 from the stage position storage area of the storage unit 22 and stores it in the storage unit 22. The stored storage length L3 and the set thickness Th of the bill S are read, and the stage position Lp is subtracted from the storage length L3 to calculate the distance between the upper surface 19a of the storage space 19 and the upper surface 12a of the stage 12. Then, the calculated distance is divided by the thickness setting value Th to calculate the number of accumulated sheets accumulated on the stage 12 at the end of accumulation.

Then, the control unit 21 transmits the calculated number of accumulated sheets and the number of stored sheets counted in the stored number counting area of the storage unit 22 to the monitoring device of the monitoring center via the banknote depositing and dispensing machine, and the accumulation process according to the current accumulation command. End.
In this manner, the banknote S is collected by the banknote storage cassette 1 of the present embodiment.

Below, the delivery process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
When receiving a payout command associated with the withdrawal transaction selected by the customer from the banknote depositing / dispensing machine, the control unit 21 of the banknote storage cassette 1 uses the retraction mechanism 11 when the press detection sensor 8 of the pickup roller 7 is in the OFF state. The tongue roller 9 is retracted to the retracted position, the stage motor 13 of the elevating mechanism is rotated to raise the stage 12, and moved to the position where the press detection sensor 8 is turned on, that is, the bill pressing position. In addition, when the upper surface of the uppermost banknote S is already in the banknote pressing position, the above operation is omitted.

  Recognizing that the uppermost banknote S is in the banknote pressing position and that the tongue roller 9 is retracted to the retracted position, the control unit 21 accumulates on the stage 12 with the pickup roller 7 as shown in FIG. The pickup roller 7 and the feed roller 3 are rotated in the feeding direction (counterclockwise in FIG. 3) while the banknote is pressed, and the uppermost banknote S is fed between the feed roller 3 and the gate roller 6 by the pickup roller 7. .

  At this time, the uppermost banknote S is fed out by the feed roller 3, and the second and subsequent banknotes S are stopped and separated by the non-rotating gate roller 6, separated into one sheet and fed out. It is sandwiched between the roller 3 and the pinch roller 5 and conveyed along the guide (not shown) in the direction of the delivery port 4. After being detected by the delivery monitoring sensor 4 a, it is carried out of the bill storage cassette 1 from the delivery port 4.

By repeating such a feeding operation, the banknote S on the stage 12 is continuously fed out.
During this feeding operation, the control unit 21 subtracts “1” from the count number of the storage number count area of the storage unit 22 every time the delivery monitoring sensor 4a detects the newly fed banknote S, and stores the number of stored sheets. Count.

  The control unit 21 rotates the stage motor 13 when detecting that the pickup roller 7 is lowered as the accumulated banknotes are reduced by the fed banknote S and the press detection sensor 8 of the pickup roller 7 is turned off. The stage 12 is raised until the pressure detection sensor 8 is turned on, and this is repeated, so that the position of the uppermost banknote S of the stacked banknotes is always set to the banknote pressing position according to the number of banknotes S being fed out. Control to maintain.

Then, when the feeding of the specified number of banknotes S in the current feeding command is finished, the control unit 21 stops the separation and stacking mechanism 2.
At this time, since the next payout banknote has been sent to the vicinity of the feed roller 3 and the gate roller 6, the control unit 21 executes a return process for returning it to a normal accumulation state.

  That is, the control unit 21 rotates the stage motor 13 and lowers the stage 12 until it reaches the accumulating operation space length L2 to secure the accumulating operation space 20, and the position of the tongue roller 9 is changed from the retracted position to the accumulating position. , The feed roller 3 and the pickup roller 7 are rotated in the stacking direction, the tongue piece roller 9 is rotated in the opposite direction (see FIG. 1), and the waiting bills are fed by the tongue piece 10 of the stacked banknotes. When the banknotes waiting to be fed are returned, the feed roller 3, the pickup roller 7, and the tongue piece roller 9 are stopped and the tongue roller 9 is moved to the retracted position, and then the stage motor 13 is rotated to pick up. The stage 12 is raised until the pressure detection sensor 8 of the roller 7 is turned on, and the stacked banknotes are sandwiched between the stage 12 and the pickup roller 7. , The bill S of the most significant is positioned in the bill pressing position, to complete the return process of feeding waiting bill.

The control unit 21 that has finished returning the banknotes to be paid out executes a confirmation process of the number of stacked sheets and the number of stacking surplus sheets at the end of feeding.
That is, the control unit 21 lowers the stage 12 while counting the output of the encoder 14 of the stage motor 13 from the banknote pressing position in the storage unit 22 separately from the count for managing the stage position Lp described above. When the movement amount of the stage 12 converted from the count number using the conversion coefficient of the storage unit 22 reaches the integrated operation space length L2 stored in the storage unit 22, the stage 12 is stopped and the integrated operation space 20 is set. The stage position Lp stored in the stage position storage area of the storage unit 22 is read out, the thickness setting value Th of the bill S stored in the storage unit 22 is read out, and the stage position Lp is set as the thickness setting value. Divide by Th to calculate the number of accumulation margins at the end of feeding.

  The control unit 21 that has calculated the number of sheets to be accumulated at the end of the feeding operation rotates the stage motor 13 again to raise the stage 12 until the pressure detection sensor 8 of the pickup roller 7 is turned on. The uppermost banknote S is positioned at the banknote pressing position, and the stage position Lp at this time is read from the stage position storage area of the storage unit 22 and stored in the storage unit 22. The storage length L3 and the thickness setting value Th of the banknote S are read, and the distance between the upper surface 19a of the storage space 19 and the upper surface 12a of the stage 12 is calculated by subtracting the stage position Lp from the storage length L3. Divide the distance by the thickness setting value Th to calculate the number of sheets accumulated on the stage 12 at the end of feeding.

Then, the control unit 21 transmits the calculated accumulated number, the accumulated margin number, and the stored number counted in the storage number count area of the storage unit 22 to the monitoring device of the monitoring center via the bill depositing / dispensing machine, The feeding process according to the command is terminated.
On the other hand, the monitoring device associates the received stacking number, stacking surplus number, and storage number at the end of stacking or feeding out with the identification number of the sender banknote depositing and dispensing machine, and the banknote storage cassette 1 of that denomination. Are stored in chronological order as the number of accumulated bills S, the number of margins for accumulation, and the number of stored bills.

  The monitoring device displays a near-full alarm of the banknote storage cassette 1 on a screen of a display unit (not shown) when the number of stacked banknote storage cassettes 1 exceeds a predetermined near full threshold value. After confirming this, the clerk transports the banknote storage cassette 1 loaded with a predetermined number of banknotes S to the banknote depositing / dispensing machine and replaces it with the banknote storage cassette 1 for which the near-full alarm has been issued.

  Further, the monitoring device displays a near-end alarm of the banknote storage cassette 1 on a screen of a display unit (not shown) when the accumulated number of banknote storage cassettes 1 is equal to or less than a predetermined near-end threshold, and notifies the monitoring center staff. Then, the clerk confirming this transports the banknote storage cassette 1 loaded with a predetermined number of banknotes S to the banknote depositing / dispensing machine and replaces it with the banknote storage cassette 1 for which the near-end alarm has been issued.

In the case where the stacking process, the feeding process, and the like are performed while managing the stage position Lp as described above, the control unit 21 of the banknote storage cassette 1 of the present embodiment performs the stacking process or the feeding process. A failure determination process for determining a failure of the position detection sensor 15 based on a logical contradiction in the detection of the light shielding plate 16 by the position detection sensor 15 is executed.
That is, the control unit 21 determines that the position detection sensor 15 causing the contradiction is a failure due to the following logical contradiction.

(1) During the process, the position detection sensor 15 specified in consideration of the light shielding plate length L1 at the stage position Lp calculated by the movement amount of the stage 12 detected by the encoder 14 is not in the ON state, that is, the light shielding plate 16. When a logical contradiction occurs in that the position detection sensor 15 is not detected, the position detection sensor 15 is determined to be faulty.

(2) During the process, when the position detection sensor 15 does not exist at the stage position Lp calculated from the movement amount of the stage 12 detected by the encoder 14 even if the light shielding plate length L1 is taken into consideration, the position detection sensor 15 When there is a logical contradiction that at least one is in the ON state, that is, the light shielding plate 16 is erroneously detected, the position detection sensor 15 is determined to be a failure.

(3) During the process, when the position detection sensor 15 that has been identified in consideration of the light shielding plate length L1 at the stage position Lp calculated by the amount of movement of the stage 12 detected by the encoder 14 detects the light shielding plate 16. When there is a logical contradiction that at least one of the other position detection sensors 15 is in the ON state, that is, the light shielding plate 16 is erroneously detected, the position detection sensor 15 is determined to be faulty.

  In this case, the position detection sensors 15 of the present embodiment are arranged at intervals equal to or greater than the light shielding plate length L1, and it is impossible for two or more position detection sensors 15 to simultaneously detect the light shielding plate 16. In addition, since the position detection sensor 15 specified by the stage position Lp normally detects the light shielding plate 16, all of the position detection sensors 15 that are in the ON state among the other position detection sensors 15 are determined to be faulty. The failed position detection sensor 15 can be identified.

(4) During processing, the number of bills S carried into or out of the bill storage cassette 1 is counted by an output signal from the delivery monitoring sensor 4a, and counted in the storage number count area of the storage unit 22 while adding or subtracting it. It is logical that the number of stored sheets and the number of stacked sheets calculated at the end of stacking or at the end of feeding are different from each other beyond a predetermined allowable range (in this embodiment, 95% or more and 105% or less of the stored sheets). When such a contradiction occurs, it is determined that the position detection sensor 15 used as a reference for resetting the stage position Lp immediately before that is a failure.

(5) When the logical contradiction described in (1) to (3) above occurs due to the position of the stage 12 calculated by the number of stored sheets counted by the delivery monitoring sensor 4a during processing, the position detection sensor 15 is determined as a failure.
In the case of (5), the failure determination of the detection sensor 15 based on the position of the stage 12 calculated based on the number of stored sheets is as follows.

That is, since the type of the banknote S stored in the banknote storage cassette 1 is known, the stacking height based on the number of stored sheets stacked on the stage 12 can be calculated.
Accordingly, if the stacking height is subtracted from the storage length L3 of the storage space 19, the stored banknotes are sandwiched between the stage 12 and the pickup roller 7 at the end of accumulation or at the end of feeding, that is, the stage 12 and the pickup roller 7. The position of the stage 12 can be calculated.

  Considering the light shielding plate length L1 in the calculated position of the stage 12, the position detection sensor 15 that should detect the light shielding plate 16 can be specified. (1) The specified position detection sensor 15 is not in the ON state (2) When the position detection sensor 15 does not exist at the calculated position of the stage 12, at least one of the position detection sensors 15 is in an ON state. (3) When the specified position detection sensor 15 detects the light shielding plate 16 In addition, when at least one of the other position detection sensors 15 is in the ON state, the position detection sensor 15 is determined to be faulty.

  In this way, when the control unit 21 determines that the position detection sensor 15 has failed, the operation of the banknote storage cassette 1 is stopped, and a failure occurrence notification that the position detection sensor 15 has failed is issued. The bill depositing / dispensing machine which has transmitted to and received the failure occurrence notification stops its operation.

The failure notification is transmitted to the monitoring device of the monitoring center, and the monitoring device that receives the notification displays the failure notification of the banknote storage cassette 1 on a screen of a display unit (not shown) and The clerk informing the clerk and confirming this exchanges the banknote storage cassette 1 loaded with a predetermined number of banknotes S to the banknote depositing / dispensing machine and exchanges it with the banknote storage cassette 1 for which the failure occurrence notification has been issued, The banknote depositing / dispensing machine to which the banknote storage cassette 1 is attached is restored.
In addition, since the failed position detection sensor 15 is known, the failed banknote storage cassette 1 is repaired.

  As described above, in this embodiment, the stage position Lp of the stage 12 is managed by the amount of movement of the stage 12 detected by the encoder 14, so that the logical position between the stage position and the detection of the light shielding plate 16 by the position detection sensor 15. Due to this contradiction, it is possible to easily determine the failure of the position detection sensor 15 and to easily calculate the number of stacked banknotes S and the number of stackable margins in the banknote storage cassette 1 in the stacking process and the feeding process. .

  Moreover, since the fact that the position detection sensor 15 has failed is notified to the monitoring device of the monitoring center, the alternative banknote storage cassette 1 can be immediately prepared and repaired, and the banknote storage in which the position detection sensor 15 has failed is stored. It becomes possible to always use the banknote storage cassette 1 that is operating normally without the cassette 1, making it easy to plan the operation plan of the banknote storage cassette 1, and efficiently operating the exchange of the banknote storage cassette 1. It is possible to reduce the waste of the banknote replenishment work due to and the waste due to erroneous detection of the banknote in the banknote storage cassette 1.

  Further, by notifying the monitoring device of the monitoring center that the position detection sensor 15 has failed, the banknote storage cassette 1 is operated without being able to accurately grasp the number of stacked sheets in the banknote storage cassette 1 or the number of stackable margins. Convenience for customers by preventing long-term stoppage of the device due to the suspension of transactions due to sudden shortage of banknotes and the occurrence of jams due to the accumulation of banknotes S when there is no stackable number of sheets Can be improved.

Furthermore, since the thickness setting value Th of the banknote S handled by the banknote storage cassette 1 is set in advance, it is possible to calculate the number of stacked sheets and the number of stackable sheets according to the thickness of various banknotes.
This is because, when handling banknotes S having different thicknesses for each country such as foreign banknotes, it is not necessary to change the assembly position of the position detection sensor 15 for each country. This is particularly useful for the banknote storage cassette 1 that is difficult to change.

In the present embodiment, it has been described that the operation of the bill storage cassette 1 is stopped when it is determined that the position detection sensor 15 has failed. The occurrence notification may be transmitted only.
In this case, the monitoring center confirms the failure occurrence notification displayed on the monitoring device, prepares an alternative banknote storage cassette 1, transports the banknote storage cassette 1 to the site, and issues a failure occurrence notification. The banknote storage cassette 1 is replaced, and repair of the banknote storage cassette 1 in which a failure has occurred is performed at an optimum timing at the monitoring center.

  In addition, until the replacement of the banknote storage cassette 1 in which the failure has occurred, the position detection sensor 15 in which the failure has occurred is degenerated, the output signal from the position detection sensor 15 is ignored, and the stage 12 detected by the encoder 14 is detected. The operation of the banknote storage cassette 1 in which a failure has occurred is continued while managing the stage position Lp according to the amount of movement. Thereby, the operation stop time of the banknote depositing / dispensing machine can be minimized, and the operating efficiency of the banknote depositing / dispensing machine can be improved.

  As described above, in this embodiment, the position detection sensors are arranged in a line along the stage moving direction, and the stage position and the position detection sensor are controlled while managing the stage position based on the movement amount of the stage detected by the encoder. Since the failure of the position detection sensor is determined based on the logical contradiction with the detection of the light shielding plate, it is possible to easily determine the failure of the position detection sensor that detects the storage amount of the bills S, and after the stacking process. In addition, it is possible to easily calculate the number of stacked bills S and the number of stackable margins in the bill storage cassette after the feeding process.

Below, the banknote storage cassette of a present Example is demonstrated using FIG. 4, FIG.
In addition, the same part as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits the description.
The position detection sensor 25 of the present embodiment has the same configuration as the position detection sensor 15 of the first embodiment, but the arrangement thereof is different as shown in FIGS. The seven position detection sensors 25a to 25g are arranged in one row along the stage moving direction, and the distance between the centers of the optical axes of the adjacent light emitting portions 18a is the light shielding plate length L1. As described above, the interval is set to be equal to or shorter than the length obtained by adding the light shielding plate length L1 to the integrated operation space length L2.

  For this reason, in the normal state of each position detection sensor 25, when the light shielding plate 16 exists between the position detection sensors 25, all the position detection sensors 25 are in the OFF state, and any one of the position detection sensors 25 is present. When detecting the presence of the light shielding plate 16, only the position detection sensor 25 is in the ON state, and the other position detection sensors 25 are in the OFF state.

Further, in the operation of securing the integrated operation space 20, any position detection sensor 25 is necessarily arranged to be in the ON state, that is, to detect the light shielding plate 16.
Note that the position detection sensors 25 of the present embodiment are arranged at equal intervals within the above-described interval range, but may be at irregular intervals as long as they are within the above-described interval range.

  In the storage unit 22 of the present embodiment, an application program having a function of executing a stacking process and a feeding process of the banknotes S described below, a failure determination process of the position detection sensor 25, a confirmation process of the number of stacked sheets and the number of stacked sheets, and the like. A cassette processing program including an application program having a function of detecting opening / closing of a cassette door (not shown) and recording the opening / closing time and the number of stored sheets at that time is stored in advance, and the cassette executed by the control unit 21 Each functional means of the bill storage cassette 1 of this embodiment is formed by the steps of the processing program.

  The storage unit 22 has a rotation amount count area for counting the number of waveforms output from the encoder 14 and a storage number count area similar to that in the first embodiment. In the present embodiment, the stage position storage area of the first embodiment is omitted.

  Further, in the storage unit 22, as in the first embodiment, the light shielding plate length L 1, the integrated operation space length L 2, the center of the optical axis of the light emitting unit 18 a of each of the position detection sensors 25 a to 25 g, and the storage space 19. The sensor positions Laa to Lgg (refer to FIG. 4) which are distances to the lower surface 19b, the storage length L3 which is the distance between the lower surface 19b and the upper surface 19a of the storage space, and the count number by the encoder 14 are moved by the stage 12. Conversion factor when converting to quantity, thickness setting value Th of the bill S to be handled, and a predetermined allowable range for determining the difference between the number of stored sheets and the number of stacked sheets as a difference (in this embodiment, 95% or more of the stored number of sheets) , 105% or less range) is preset and stored.

Below, the collection process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
When the stacking instruction is received from the banknote depositing and dispensing machine, the control unit 21 of the banknote storage cassette 1 sets each part of the banknote storage cassette 1 in a stacking waiting state.

  That is, as in the first embodiment, when the pressure detection sensor 8 is not in the ON state (in the OFF state), the control unit 21 retracts the tongue piece roller 9 to the retracted position and rotates the stage motor 13. The stage 12 is raised and moved to a position where the press detection sensor 8 is turned on, that is, a bill press position. In addition, when the upper surface of the uppermost banknote S is already in the banknote pressing position, the above operation is omitted.

The control unit 21 that has recognized that the uppermost banknote S is in the banknote pressing position lowers the stage 12 while counting the output of the encoder 14 of the stage motor 13 from the banknote pressing position in the storage unit 22, and the count number When the movement amount of the stage 12 converted using the conversion coefficient of the storage unit 22 reaches the integrated operation space length L2 stored in the storage unit 22, the stage 12 is stopped to secure the integrated operation space 20. The tongue piece roller 9 is moved from the retracted position to the accumulation position.
At the time of securing the stacking operation space 20, the control unit 21 executes a process for checking the stacking surplus number of banknotes S.

  That is, the control unit 21 monitors the output signals from the position detection sensors 25a to 25e, and the position detection sensor 25 changes from the OFF state to the ON state and from the ON state to the OFF state until the integrated operation space 20 is secured. In other words, if any of the position detection sensors 25 detects the presence of the light shielding plate 16 provided on the stage 12, the output of the encoder 14 from the detection position until the accumulation operation space 20 is ensured is output. Separately from the count for measuring the integrated operation space length L2, the count is counted in the rotation amount count area of the storage unit 22, and when the integrated operation space 20 is secured, the count is counted in the rotation amount count area. The counted number of the encoder 14 and the sensor position of the position detection sensor 25 that detects the light shielding plate 16 stored in the storage unit 22; Calculation coefficient, light shielding plate length L1, reads a thickness setting value Th of the bill S, calculates the integrated margin number during integration operation is started on the basis of the these and the stage moving direction.

  For example, when the position detection sensor 25d changes from the OFF state to the ON state during the descent like the stage 12 indicated by a two-dot chain line in FIG. 4, counting from the detection position by the position detection sensor 25d is started. However, when the ON state is subsequently changed to the OFF state, the count number in the rotation amount count area of the storage unit 22 is once cleared, the counting from the detection position is started again, and the integrated operation space 20 is secured. In addition, the count number counted in the rotation amount count area, the sensor position Ldd (see FIG. 4) of the position detection sensor 25d, the conversion coefficient, the light shielding plate length L1, and the thickness setting value Th of the bill S are read out, and the rotation amount count area The amount of movement Ls from the position detection sensor 25d is calculated by multiplying the count number counted in step 1 by the conversion coefficient.

Since the change in the detection state in this case is a change due to the lower end of the light shielding plate 16 being lowered (the upper surface 12a of the stage 12), the position Ld of the upper surface 12a of the stage 12 is calculated by subtracting the movement amount Ls from the sensor position Ldd. .
Since this calculated value is the distance between the lower surface 19b of the storage space 19 and the upper surface 12a of the stage 12, this is divided by the thickness setting value Th to calculate the stacking margin number at the start of the stacking operation.

And the control part 21 transmits the calculated accumulation | storage margin number to the monitoring apparatus of a monitoring center via a banknote depositing / withdrawing machine.
The subsequent stacking operation by the banknote storage cassette 1 and the operation until the stacking of the banknotes S according to the current stacking command are the same as those in the first embodiment, and a description thereof will be omitted.

  When the stacking of the bills S by the current stacking command is finished, the control unit 21 raises the stage 12 from the stage motor 13 in the same manner as in the first embodiment so as not to make the stacked bills free. The stacked banknotes are sandwiched between the pickup roller 7 and the uppermost banknote S is positioned at the banknote pressing position, and the stacking number confirmation process at the end of stacking is executed.

  That is, the control unit 21 monitors output signals from the position detection sensors 25a to 25e, and the position detection sensor 25 is switched from the OFF state to the ON state until the stacked banknotes are sandwiched between the stage 12 and the pickup roller 7. When the state changes from the ON state to the OFF state, that is, when any of the position detection sensors 25 detects the presence of the light shielding plate 16 provided on the stage 12, from the detection position to the end of the stacking of stacked banknotes. The output count from the encoder 14 is counted in the rotation amount count area of the storage unit 22 and when the stacked banknotes are sandwiched, the count number of the encoder 14 counted in the rotation amount count area and the storage unit 22 The sensor position of the position detection sensor 25 that has detected the stored light shielding plate 16, the conversion coefficient, the light shielding plate length L1, the storage length L3, Reading a thickness set value Th of the bill S, calculates the number of stacked at integrated termination based on the these and the stage moving direction.

  For example, when the position detection sensor 25d changes from the OFF state to the ON state during ascending as in the stage 12 indicated by a two-dot chain line in FIG. 5, the position detection sensor 25d starts counting from the detection position. However, when the state subsequently changes from the ON state to the OFF state, the count number in the rotation amount count area of the storage unit 22 is once cleared, the counting from the detection position is started again, and the sandwiching of the stacked bills is finished. Sometimes, the count number counted in the rotation amount count area, the sensor position Ldd (see FIG. 5) of the position detection sensor 25d, the conversion coefficient, the light shielding plate length L1, the storage length L3, and the thickness setting value Th of the bill S are set. The amount of movement Ls from the position detection sensor 25d is calculated by multiplying the count number read in the rotation amount count area by the conversion coefficient.

  Since the change in the detection state in this case is a change due to the lower end of the rising light shielding plate 16, the movement amount Ls and the light shielding plate length L1 are added to the sensor position Ldd to calculate the position of the upper surface 12a of the stage 12. By subtracting this calculated value from the storage length L3, the distance between the upper surface 19a of the storage space 19 and the upper surface 12a of the stage 12 is calculated, and this is divided by the thickness set value Th to complete the integration at the end of the integration. Calculate the number of sheets.

Then, the control unit 21 transmits the calculated number of accumulated sheets and the number of stored sheets counted in the stored number counting area of the storage unit 22 to the monitoring device of the monitoring center via the banknote depositing and dispensing machine, and the accumulation process according to the current accumulation command. End.
In this manner, the banknote S is collected by the banknote storage cassette 1 of the present embodiment.

Below, the delivery process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
Since the operation from the time when the control unit 21 of the banknote storage cassette 1 of the present embodiment receives the payout command to the end of the payout waiting bill return processing is the same as that of the first embodiment, the description thereof is omitted.

The control unit 21 that has finished returning the banknotes to be paid out executes a banknote amount confirmation process at the end of the payout.
That is, the control unit 21 lowers the stage 12 while counting the output of the encoder 14 of the stage motor 13 from the banknote pressing position in the storage unit 22, and the stage converted from the count number using the conversion coefficient of the storage unit 22. When the movement amount of 12 reaches the integrated operation space length L2 stored in the storage unit 22, the stage 12 is stopped to secure the integrated operation space 20.

  At the time of securing the integrated operation space 20, the control unit 21 monitors the output signal from each position detection sensor 25 as in the case of the start of the integrated operation, and until the integrated operation space 20 is secured. If any of the position detection sensors 25 detects the presence of the light shielding plate 16, the number of outputs counted from the encoder 14 until the accumulation operation space 20 is secured from the detected position is calculated as the accumulation operation space described above. Separately from the count for measuring the length L2, the count is performed in the rotation amount count area of the storage unit 22, and when the integrated operation space 20 is secured, the count number of the encoder 14 counted in the rotation amount count area, and the storage The sensor position of the position detection sensor 25 that has detected the light shielding plate 16 stored in the unit 22, the conversion coefficient, the light shielding plate length L1, and the thickness setting value Th of the bill S are read out. Based on the al and the stage moving direction, as in the case when the integrated operation starts, and calculates the integrated margin the number of feeding end.

  The control unit 21 that has calculated the number of sheets to be accumulated at the end of the feeding operation rotates the stage motor 13 again to raise the stage 12 until the pressure detection sensor 8 of the pickup roller 7 is turned on. The stacked banknotes are sandwiched between them, and the uppermost banknote S is positioned at the banknote pressing position.

  At this time, the control unit 21 monitors the output signal from each position detection sensor 25 as in the case of the end of the accumulation, and until the stacked banknotes are sandwiched between the stage 12 and the pickup roller 7. When the position detection sensor 25 detects the presence of the light shielding plate 16, the count number of the output from the encoder 14 from the detection position until the sandwiching of the stacked banknotes is completed is counted in the rotation amount count area of the storage unit 22. When the stacked banknotes are sandwiched, the count number of the encoder 14 counted in the rotation amount count area, the sensor position of the position detection sensor 25 that detects the light shielding plate 16 stored in the storage unit 22, the conversion coefficient, Reading the light shielding plate length L1, the storage length L3, the thickness setting value Th of the bill S, and calculating the number of stacked sheets at the end of stacking based on these and the stage moving direction In the same manner as, to calculate the number of stacked pay-out at the end.

Then, the control unit 21 transmits the calculated accumulated number, the accumulated margin number, and the stored number counted in the storage number count area of the storage unit 22 to the monitoring device of the monitoring center via the bill depositing / dispensing machine, The feeding process according to the command is terminated.
Subsequent treatment at the monitoring center is the same as that in the first embodiment, and a description thereof will be omitted.

During the above-described stacking process or feeding process, the control unit 21 of the banknote storage cassette 1 according to the present embodiment determines a failure of the position detection sensor 25 based on a logical contradiction in the detection of the light shielding plate 16 by the position detection sensor 25. The failure determination process to be executed is executed.
That is, the control unit 21 determines a failure of the position detection sensor 25 based on the following logical contradiction.

(6) When a logical contradiction arises during processing that at least two position detection sensors 25 are in the ON state at the same time, that is, the presence of the light shielding plate 16 is simultaneously detected, the position detection sensor 25 fails. Determine.
In this case, the position detection sensors 25 of the present embodiment are arranged at intervals equal to or longer than the light shielding plate length L1, and it is impossible for two or more position detection sensors 25 to simultaneously detect the light shielding plate 16. Therefore, the occurrence of a failure in the position detection sensor 25 can be determined, and any or all of the position detection sensors 25 that simultaneously detect the light shielding plate 16 are determined to be in failure.

(7) During the processing, while the stage 12 for securing the stacking operation space 20 is being lowered, or while the topmost banknote S is being raised to the bill pressing position after securing the stacking operation space 20, that is, the topmost When the bill S is moved up and down in the stacking operation space 20, a logical contradiction occurs that none of the position detection sensors 25 is turned on, that is, the presence of the light shielding plate 16 is not detected. The failure of the position detection sensor 25 is determined.

  In this case, the position detection sensors 25 of the present embodiment are arranged at intervals equal to or shorter than the accumulation operation space length L2 plus the light shielding plate length L1, and the accumulation operation space 20 of the uppermost banknote S is disposed. One of the position detection sensors 25 must detect the light shielding plate 16 during the ascending / descending operation, and it is impossible that none of the position detection sensors 25 detects the presence of the light shielding plate 16. Therefore, it is possible to determine the occurrence of a failure in the position detection sensor 25, and any or all of the position detection sensors 25a to 25g are determined as a failure.

(8) During processing, the number of the bills S carried into or out of the bill storage cassette 1 is counted according to the output signal from the delivery monitoring sensor 4a, and counted in the storage number count area of the storage unit 22 while adjusting it. The number of stored sheets and the number of stacked sheets calculated when the logical contradiction of the above (7) does not occur when the number of stacked sheets is confirmed at the end of stacking or at the end of feeding are stored in a predetermined allowable range (stored in this embodiment). When a logical contradiction occurs in which the difference exceeds 95% or more and 105% or less of the number of sheets, the position detection sensor 25 that is the basis for calculating the number of accumulated sheets has failed during the confirmation process. judge.

  In addition to the above, the control unit 21 performs the failure determination process described below according to the position of the stage 12 calculated based on the number of stored sheets counted by the delivery monitoring sensor 4a, similarly to the failure determination process (5) of the first embodiment. Execute.

Since the type of the banknote S stored in the banknote storage cassette 1 of this embodiment is known, the stacking height based on the number of stored sheets stacked on the stage 12 can be calculated.
Accordingly, if the stacking height is subtracted from the storage length L3 of the storage space 19, the stored banknotes are sandwiched between the stage 12 and the pickup roller 7 at the end of accumulation or at the end of feeding, that is, the stage 12 and the pickup roller 7. The position of the stage 12 can be calculated.

(9) The logic that the position detection sensor 25 specified in consideration of the light shielding plate length L1 at the position of the stage 12 calculated based on the number of stored sheets as described above is not in an ON state, that is, the light shielding plate 16 is not detected. When a general contradiction occurs, the position detection sensor 25 is determined to be faulty.

(10) If the position detection sensor 25 does not exist at the position of the stage 12 calculated based on the number of stored sheets as described above even if the light shielding plate length L1 is taken into consideration, at least one of the position detection sensors 25 is in the ON state. If there is a logical contradiction that there is, that is, the light shielding plate 16 is erroneously detected, the position detection sensor 25 is determined to be faulty.

(11) When the position detection sensor 25 specified in consideration of the light shielding plate length L1 at the position of the stage 12 calculated based on the number of stored sheets as described above detects the light shielding plate 16, another position detection sensor When at least one of 25 is in an ON state, that is, when there is a logical contradiction that the light shielding plate 16 is erroneously detected, the position detection sensor 25 is determined to be a failure.

  In this case, since the position detection sensor 25 specified by the position of the stage 12 calculated based on the number of stored sheets normally detects the light shielding plate 16, the position detection sensor that is in the ON state among the other position detection sensors 25. All of 25 can be determined to be faulty, and the faulty position detection sensor 25 can be identified.

In this way, when the control unit 21 determines that the position detection sensor 25 has failed, as in the case of the first embodiment, the operation stop of the bill storage cassette 1 or the failure occurrence notification to the monitoring device of the monitoring center. Send only.
Since the processing in the monitoring center in these cases is the same as that in the first embodiment, the description thereof is omitted.

  In this embodiment, when it is determined that the position detection sensor 25 has failed, the operation of the banknote storage cassette 1 is continued and only the failure occurrence notification is transmitted to the monitoring device of the monitoring center. When the generated position detection sensor 25 is degenerated, the output signal from the position detection sensor 25 is ignored, and the banknote in which a failure has occurred while managing the position of the stage 12 based on the amount of movement of the stage 12 detected by the encoder 14. The operation of the storage cassette 1 is continued.

  As described above, in this embodiment, the position detection sensors are arranged at intervals of not less than the light shielding plate length L1 and not more than the integrated operation space length L2 plus the light shielding plate length L1. Since the position of the stage is calculated based on the amount of stage movement detected by the encoder from when the light-shielding plate is detected, the position detection sensor can easily break down due to a logical contradiction in the detection of the light-shielding plate by the position detection sensor. In addition to being able to determine the number of stacked bills S and the number of stackable margins in the bill storage cassette in the stacking process and the payout process, the same effects as in the first embodiment can be obtained. it can.

In the description of the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The storage unit 22 of this embodiment stores in advance a cassette processing program similar to that of the above-described embodiment 1, and each function of the banknote storage cassette 1 of this embodiment according to the steps of the cassette processing program executed by the control unit 21. Means are formed.

  Further, the storage unit 22 has a stage position storage area and a storage number count area similar to those in the first embodiment, and the storage number at the end of one transaction counted by the output signal from the delivery monitoring sensor 4a. A transaction history information storage area for storing the distance between the stage position Lp and the upper surface 19a of the storage space 19 when calculating the number of accumulated sheets as transaction history information is secured in advance.

  Further, in the storage unit 22, as in the first embodiment, the light shielding plate length L 1, the integrated operation space length L 2, the center of the optical axis of the light emitting unit 18 a of each of the position detection sensors 25 a to 25 g, and the storage space 19. The sensor positions Laa to Lgg (refer to FIG. 4) which are distances to the lower surface 19b, the storage length L3 which is the distance between the lower surface 19b and the upper surface 19a of the storage space, and the number of counts by the encoder 14 are the amount of movement of the stage 12. A conversion factor for conversion, a thickness setting value Th of the banknote S to be handled, and a predetermined allowable range for determining a difference between the number of stored sheets and the number of stacked sheets (in this embodiment, 95% or more of stored sheets, 105 % Range) is preset and stored.

Below, the collection process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
The operation from the time when the control unit 21 of the banknote storage cassette 1 according to the present embodiment receives the stacking command to the time when the stacking number confirmation processing at the end of stacking is completed is the same as that of the first embodiment, so the description will be given. Omitted.

  The control unit 21 that has finished the process of checking the number of stacked sheets at the end of stacking, the number of stored sheets at the end of the stacked sheet number checking process, that is, at the end of a deposit transaction or the like counted by the output signal from the delivery monitoring sensor 4a. The distance between the stage position Lp and the upper surface 19a of the storage space 19 when the number of accumulated sheets at the end is calculated is stored in the transaction history information storage area of the storage unit 22 as transaction history information.

  Then, the control unit 21 transmits the calculated number of accumulated sheets and the number of stored sheets counted in the stored number counting area of the storage unit 22 to the monitoring device of the monitoring center via the banknote depositing and dispensing machine, and the accumulation process according to the current accumulation command. End.

Below, the delivery process of the banknote S by the banknote storage cassette 1 of a present Example is demonstrated.
The operation from the time when the control unit 21 of the banknote storage cassette 1 according to the present embodiment receives the feeding command to the time when the stacking number confirmation processing at the end of the feeding is completed is the same as that in the first embodiment, so the description thereof will be given. Omitted.

  The control unit 21 that has completed the confirmation process of the accumulated number at the end of feeding and the remaining number of accumulated sheets, determines the stored number at the end of the accumulated number confirmation process, that is, at the end of the withdrawal transaction, and the accumulated number at the end of the delivery. The calculated distance between the stage position Lp and the upper surface 19a of the storage space 19 is stored in the transaction history information storage area of the storage unit 22 as transaction history information.

Then, the control unit 21 transmits the calculated accumulated number, the accumulated margin number, and the stored number counted in the storage number count area of the storage unit 22 to the monitoring device of the monitoring center via the bill depositing / dispensing machine, The feeding process according to the command is terminated.
Subsequent treatment at the monitoring center is the same as that in the first embodiment, and a description thereof will be omitted.

  When the number of transactions becomes 10 during execution of such cassette processing, the control unit 21 obtains transaction history information for the past 10 transactions including the current transaction from the transaction history information storage area of the storage unit 22. Reading, the number of changes in the number of stored sheets between two consecutive transactions, that is, the number of banknotes S newly delivered from the delivery port 4 or the number of delivery of banknotes S newly delivered from the delivery port 4 And the amount of change in the stage position Lp between two consecutive transactions, that is, the amount of change in the distance between the stage position Lp and the upper surface 19a of the storage space 19 is calculated, and the amount of change in the stage position Lp is calculated by the number of delivered sheets. The thickness of the banknote S in the transaction is calculated by dividing the thickness of the banknote S in the transaction calculated by the transaction history information for the past 10 transactions, and the average value of the banknote thickness is calculated. , A thickness set value Th of the bill S that is stored in the storage unit 22 is updated by rewriting the average value of the calculated bill thickness.

  In this case, when the average value of the banknote thickness of the past 10 transactions is 80% or more and 120% or less of the thickness setting value Th stored in the storage unit 22 at that time, the banknote thickness is normally detected. When it is determined that the thickness is set and the thickness set value Th is updated and the thickness exceeds the range, it is determined that the banknote thickness cannot be normally detected due to a stacking failure or the like. The stored thickness setting value Th is continuously used without updating the setting value Th.

As a result, it is possible to prevent an increase in error in the calculated value of the number of accumulated sheets and the number of accumulated margins.
In addition, although the present Example demonstrated as calculating the average value of banknote thickness for every 10 transactions, the number of transactions which calculate the average value of banknote thickness is not restricted to the above, and should just be two or more transactions, The average value may be calculated not as a plurality of transactions but as a moving average of a plurality of transactions.

  In the present embodiment, the case of the first embodiment has been described as an example, but the same applies to the case of the second embodiment. In this case, the transaction history information stored in the transaction history information storage area of the storage unit 22 is not the distance between the stage position Lp and the upper surface 19a of the storage space 19, but the amount of movement of the stage 12 and the sensor position. The distance between the position of the upper surface 12a of the stage 12 and the upper surface 19a of the storage space 19 calculated based on the above is stored.

  As described above, in the present embodiment, in addition to the same effects as those of the first embodiment or the second embodiment, the degree of damage of the banknote S stored for each banknote storage cassette 1 and the denomination stored therein are determined. Differences in the thickness of stacked banknotes generated due to differences in banknote thickness can be detected and corrected, and the number of stacked sheets and the number of stackable margins in the banknote storage cassette 1 can be calculated more accurately.

  Moreover, it becomes easier to plan the operation plan of the banknote storage cassette 1, and it is possible to reduce the waste of the banknote replenishment work and reduce the waste due to erroneous detection of the banknote in the banknote storage cassette 1. it can.

Furthermore, in each said Example, although the exchangeable banknote storage cassette was demonstrated to the example, even if it applies to banknote storage fixed to apparatuses, such as a banknote depositing / withdrawing machine, the same effect can be acquired.

  Further, in each of the above embodiments, the number of stored banknotes S has been described as being counted by a delivery monitoring sensor provided at the delivery port. However, instead of the number of counts by the delivery monitoring sensor, a banknote depositing and dispensing machine as a host device is used. However, you may make it use the number of sheets conveyed and accommodated in each banknote storage cassette.

  Furthermore, in each said Example, although the control part provided in the banknote storage cassette demonstrated as performing each process mentioned above, the cassette processing program and various data which were stored in the memory | storage part of a banknote storage cassette, It may be stored in the storage unit of the deposit / withdrawal machine, and the control unit of the banknote depositing / dispensing machine may determine a failure or the like of the position detection sensor based on a signal from the position detection sensor.

  Further, in each of the above embodiments, the bill storage cassette has been described as determining the failure of the position detection sensor based on the difference between the stored storage number and the calculated accumulated number ((4) of Example 1, In the second embodiment (see (8)), the position detection sensor malfunctions due to a logical contradiction between the number of stored sheets and the number of stacked sheets based on the number of stored sheets, the number of stacked sheets, and the number of stacking sheets received by the monitoring device of the monitoring center. You may make it determine.

  Furthermore, in each said Example, although the paper sheet handling apparatus demonstrated as the banknote depositing / withdrawing machine which handles the banknote S, a paper sheet handling apparatus is not restricted to the above, The check and goods as paper sheets It may be a device that handles tickets or the like, or a printer as a paper sheet handling device that is remotely managed using a network. In the case of this printer, the present invention can be applied to management of the remaining amount of paper as paper sheets. In short, the present invention can be applied to any apparatus that manages the number of sheets or the number of sheets that can be accumulated.
