Abstract

<P>PROBLEM TO BE SOLVED: To easily attain a desired passage ratio that takes into consideration both operational efficiency and consideration for customers. <P>SOLUTION: An identification sensor S measures the light transmittance of a bill accepted. When the light transmittance measured by the identification sensor S exceeds a predetermined "criterion value", a control unit C serving as a fatigue determining part determines that the bill accepted is a fatigued bill. An acceptance exclusion means R excludes the accepted bill from bills to be stored if it is determined as a fatigued bill by the control unit C. The control unit C serving as a computing part calculates a "passage ratio" as the ratio of bills not determined to be fatigued bills to the bills accepted. The control unit C serving as a passage ratio control part compares a "term-based passage ratio" which is the passage rate of bills accepted within a predetermined period with "desired passage ratio" which is a preset desired value of passage ratio, and performs control in such a way as to gradually increase or decrease the criterion value so that the term-based passage ratio approaches the desired passage ratio. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a circulation-type banknote handling apparatus that stores accepted banknotes received from the outside as stored banknotes and discharges the stored banknotes to the outside as necessary, and in particular, fatigue banknotes ( The present invention relates to a banknote handling apparatus that excludes accepted banknotes determined to be non-paid bills from stored banknotes.

Conventionally, the circulation (refluxing) banknote handling apparatus as described above is described in Patent Document 1 and Patent Document 2. What is described in Patent Document 1 ([0005], [0010] column, FIG. 3, etc.) is a circulation note of a region where the device is used on the assumption that the degree of banknote fouling varies depending on the distribution region. Is taken into consideration so that determination criteria corresponding to can be set. In addition, what is described in Patent Document 2 (Claims and the like) is considered so that the criterion can be automatically changed according to the remaining amount in order to prevent shortage of stored banknotes.
Japanese Patent Laid-Open No. 5-101251 Japanese Patent No. 2530850

  By the way, the following can be said when considering the “passing rate” of banknotes, which is the ratio of banknotes that are not determined as fatigue banknotes (damaged banknotes) based on predetermined criteria. That is, from the viewpoint of the operational efficiency (financial efficiency) of the apparatus, it is desirable to loosen the judgment criteria in order to increase the passing rate. On the other hand, from the viewpoint of consideration for customers who receive banknotes by withdrawal or the like, it is desirable to make the judgment criteria strict even if the passage rate is low. Therefore, it is desirable to set a criterion that achieves the target passing rate considering both viewpoints.

  In order to always maintain a constant target passing rate regardless of the region, the one described in Patent Document 1 summarizes the degree of fouling in actual circulation banknotes as statistical data in a normal distribution, and based on this, a criterion for judgment Is set automatically. Therefore, there is a drawback that complicated statistical processing based on a huge amount of data is required.

  In addition, in the device described in Patent Document 2, priority is given to the operational efficiency of the apparatus, and the determination standard (and thus the target passage rate itself) is unilaterally changed from the aspect of the remaining amount of stored bills. For this reason, there is a problem that the viewpoint of consideration for customers is essentially lacking.

  The present invention has been made in consideration of such points, and an object thereof is to provide a banknote handling device that can easily obtain a target passing rate considering both operational efficiency and consideration for customers. To do.

  1st invention accommodates the acceptance banknote received from the outside as a storage banknote, In the circulation type banknote handling apparatus which discharge | releases this storage banknote outside as needed, the transmission which measures the light transmittance of the said reception banknote A rate determination unit, a fatigue determination unit that determines that the received banknote is a fatigue banknote when the light transmittance measured by the measurement unit exceeds a predetermined determination reference value, and the determination unit determines that the banknote is a fatigue banknote. An acceptance exclusion means for excluding the accepted banknote from the stored banknote, an arithmetic unit for calculating a pass rate that is a ratio of banknotes that are not determined as fatigue banknotes by the determination unit among the accepted banknotes, and receiving within a predetermined period. The period passage rate that is the passage rate of the accepted banknote and the target passage rate that is a preset target value of the passage rate are compared, and the period passage rate approaches the target passage rate. A banknote handling apparatus characterized by comprising: a passing rate control unit for increasing / decreasing the criterion value.

  According to the first aspect of the present invention, the pass rate during operation can be gradually brought closer to the target pass rate by simply gradually increasing / decreasing the determination reference value in the direction in which the period pass rate approaches the target pass rate. .

  According to a second invention, in the first invention, a pass rate setting means for arbitrarily setting the target pass rate is further provided.

  According to the second aspect of the present invention, the balance between operational efficiency and customer consideration can be arbitrarily adjusted by setting the target passing rate.

  According to a third invention, in the first or second invention, further provided is a reference value adjusting means for arbitrarily increasing or decreasing the determination reference value.

  According to the third aspect of the present invention, the determination reference value can be directly adjusted manually, and the convenience of the administrator can be achieved.

  As described above, according to the present invention, it is possible to easily obtain a target passing rate in consideration of both operational efficiency and consideration for customers without performing complicated statistical processing or the like.

  Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 thru | or FIG. 4 is a figure which shows the banknote depositing / withdrawing apparatus as one Embodiment of the banknote handling apparatus by this invention. Hereinafter, the configuration, operation, operational effects, and modifications of the present embodiment will be described in order.

[Constitution]
The banknote depositing / withdrawing apparatus shown in FIG. 1 is configured as a circulation type depositing / dispensing apparatus that stores deposited banknotes (accepted banknotes) received from the outside as stored banknotes and discharges the stored banknotes to the outside as necessary. .

  This banknote depositing / withdrawing apparatus includes a housing 10 and an annular circumferential conveyance path 3 a provided at a substantially central portion in the housing 10. Moreover, in the housing | casing 10, the banknote feeding unit 2, the banknote accommodating part 6, the banknote discharge | release unit 8, the withdrawal rejection part 4, and the banknote collection cassette 7 are arrange | positioned so that the outer periphery of the circulation conveyance path 3a may be surrounded. ing. In addition, the banknote depositing / withdrawing apparatus includes a control unit C described later in the housing 10.

  Moreover, the connection conveyance path 3b of the banknote which connects between the feeding unit 2, each accommodating part 6, the discharge | release unit 8, the withdrawal rejection part 4, the collection | recovery cassette 7, and the circulation conveyance path 3a is formed, respectively. A banknote identification sensor S for identifying a denomination or the like of a banknote passing there is provided on the right side portion of the circulation transport path 3a. Note that swinging path switching means (not shown) for switching the banknote transport path between the circulation transport path 3a and each connection transport path 3b is disposed along the circulation transport path 3a.

  As shown in FIGS. 1 and 4, on the front surface of the housing 10, a banknote receiving port 12 corresponding to the feeding unit 2 and a banknote outlet 14 corresponding to the discharging unit 8 are provided. The collection cassette 7 is detachably attached to the housing 10. Further, a display / operation unit 11 (FIG. 4) is provided on the upper surface of the front portion of the housing 10.

  In FIG. 1, the feeding unit 2 is for introducing the deposited banknotes inserted into the receiving port 12 and feeding the banknotes to the circulation path 3 a side. Moreover, each banknote storage part 6 is for storing a banknote according to the recognition result by the identification sensor S according to the denomination, and is usually for a thousand yen banknote and for a 2,000 yen / 5,000 yen banknote (mixing). And it is divided into three storage units for 10,000 yen bills. And the discharge | release unit 8 discharge | releases the banknote taken out from each accommodating part 6 from the exit 14, and is for using these banknotes for extraction outside.

  The withdrawal reject unit 4 is for storing “withdrawal reject banknote” to be described later. The collection cassette 7 is for storing banknotes collected from each storage unit 6. The collection cassette 7 is also used to store “overflow bills” to be described later. In addition, the said discharge | release unit 8 serves also as the money_receiving | payment rejection part from which the "payment rejection banknote" mentioned later is discharged | emitted.

  Since specific configurations of the feeding unit 2, the storage units 6, the discharge unit 8, the withdrawal rejection unit 4, the collection cassette 7, and the like can be used, detailed descriptions are omitted. To do. The control unit C shown in FIG. 1 takes out the stored banknotes stored in each storage unit 6 from the storage unit 6 and discharges them from the outlet 14 in accordance with a withdrawal instruction from the outside. Control.

  Next, a configuration related to fatigue determination of accepted banknotes (deposited banknotes) will be described mainly with reference to FIG.

  As shown in FIG. 2, the identification sensor S is connected to the control unit C. The identification sensor S also has a function as a transmittance measuring unit that measures the light transmittance of the accepted banknote. Then, when the light transmittance measured by the identification sensor S as the measurement unit (for example, the transmittance at the folded fold portion at the center of the bill) exceeds a predetermined “judgment reference value”, the control unit C It has a function as a fatigue judgment part which judges an acceptance banknote as a fatigue banknote. As the light transmittance, a relative value with respect to the transmittance at the blank paper level can also be used.

  In addition, acceptance exclusion means R is connected to the control unit C. This acceptance exclusion means R is configured to exclude the accepted banknotes determined as fatigue banknotes from the stored banknotes by the control unit C as a fatigue determination unit. Specifically, the above path switching means for switching the transport path of the accepted banknotes to the discharge unit 8 (FIG. 1) as a deposit reject unit has a function as the acceptance exclusion means R.

  The control unit C further functions as a calculation unit that calculates a “passage rate” that is a ratio of banknotes that are not determined as fatigue banknotes among the accepted banknotes, and as a pass rate control unit for controlling this pass rate. It has a function. The control unit C as a passage rate control unit obtains a “period passage rate” that is a passage rate for accepted banknotes received within a predetermined period and a “target passage rate” that is a preset target value of the passage rate. In comparison, control is performed such that the determination reference value is gradually increased / decreased in a direction in which the period passing rate approaches the target passing rate.

  Here, it is considered that there is a correlation between the determination reference value of the transmittance and the passage rate of the accepted banknote. That is, generally, if the judgment reference value is lowered (strict) (the number of banknotes judged as fatigued banknotes increases), the passage rate decreases, and if the judgment reference value is increased (slowly) (the banknotes judged as fatigued banknotes) (Decrease) the passing rate increases. However, since the quantitative relationship between the determination reference value and the passing rate depends on the distribution of the degree of fatigue (transmittance) in the population of accepted banknotes, it is difficult to predict. For this reason, it is difficult to predict how much the criterion value is increased or decreased to achieve the target passing rate.

  Therefore, the passage rate control unit of the present invention gradually increases / decreases the determination reference value (for example, in units of 0.5%) in the direction in which the period passage rate approaches the target passage rate, and as a result, the target passage rate is obtained. Is taken into consideration to obtain a value close to. For example, with the passage rate within one business day as the period passage rate, control is performed to increase or decrease the judgment reference value by one step (0.5%) every day until the target passage rate is achieved. It can be carried out.

  As shown in FIG. 1, the control unit C is connected with a passing rate setting means 11a for arbitrarily setting a target passing rate and a reference value adjusting means 11b for arbitrarily increasing / decreasing a judgment reference value. Has been. These means 11a and 11b can be provided as operation keys (and a display screen for confirmation) in the display / operation unit 11 (FIG. 4). For example, the means 11a and 11b can increase or decrease the target passing rate and the determination reference value in units of 0.5%.

[Operation]
Next, (1) basic operation of the banknote depositing and dispensing device and (2) passage rate control operation (specific example) will be described.

(1) Basic operation of banknote deposit and withdrawal device
(1-1) Depositing Operation In FIG. 1, banknotes inserted into the receiving port 12 are fed one by one from the feeding unit 2 to the circulating transport path 3a through the connection transport path 3b. The banknotes fed out to the circulation conveyance path 3a are conveyed in the counterclockwise direction along the conveyance path 3a. The banknotes transported through the circulation transport path 3a are identified by the identification sensor S during one round and stored in the corresponding denomination storage unit 6.

(1-2) Withdrawing operation The banknote depositing / withdrawing apparatus performs a dispensing operation as exemplified below according to the amount of the banknote to be withdrawn.

(1-2-1) Withdrawal amount of 3,000 yen (1,000 yen) In this case, three (one) thousand yen bills fed out from the storage unit 6 for thousand yen bills are connected to the transport path 3b. The sheet is fed out one by one (only one sheet) to the circumferential conveyance path 3a. The banknotes fed out to the circulation transport path 3a are transported in the clockwise direction along the circulation transport path 3a, and sent to the banknote discharge unit 8 without receiving denomination identification by the identification sensor S. When the three (one) thousand-yen banknotes are fed, the discharge unit 8 discharges the banknotes in a bundled state (as it is in the case of one sheet) so as to protrude from the outlet 14.

(1-2-2) Withdrawal amount of 7,000 yen In this case, first, only the first banknote is paid out from the storage section 6 for 2,000 yen / 5,000 yen banknote, and the watch is moved along the circulation path 3a. It is conveyed in the turning direction. This bill is sent to the discharge unit 8 in the same manner as in the case of (2-2-1) above after receiving the denomination identification by the identification sensor S while making one or more rounds of the circulation transport path 3a.

  If the denomination of the first banknote is 5,000 yen, two thousand-yen banknotes are drawn out from the storage section 6 for the thousand-yen banknote as the remaining 2,000 yen, and the above (2-2-1) As in the case, it is sent to the discharge unit 8 without denomination identification.

  Next, when the denomination of the first banknote is 2,000 yen, only one second banknote is paid out from the storage unit 6 for 2,000 yen / 5,000 yen banknote, and the gold is sent in the circulation path 3a. Receive species identification. If the denomination of the second banknote is 5,000 yen, the 5,000 yen banknote is sent to the discharge unit 8 and the dispensing operation is completed. On the other hand, if the denomination of the second banknote is 2,000 yen, the 2,000-yen banknote is sent to the discharge unit 8 and the remaining 3,000 yen is sent from the storage unit 6 for the thousand-yen banknote. Three yen bills are fed out and sent to the discharge unit 8 without denomination identification.

  In addition, all the banknotes sent to the discharge | release unit 8 are discharge | released outside from the taking-out port 14 like the case of said (1-2-1).

(1-3) Collecting operation For example, when the business day is over and you want to collect all the banknotes in the storage unit 6 or only the amount equivalent to the sales proceeds, the banknotes drawn out from the storage unit 6 are sequentially The bill collection cassette 7 can be accommodated from the circulation conveyance path 3a through the connection conveyance path 3b. In addition, even if any of the storage units 6 is full, when a corresponding denomination banknote is further accepted, the banknote is recovered as an “overflow banknote” from the circulation conveyance path 3a through the connection conveyance path 3b. It is stored in the cassette 7.

(1-4) Rejection operation When there is a banknote that is determined as a fatigue banknote by the control unit (fatigue determination unit) U based on the light transmittance measured by the identification sensor S in the received banknote (accepted banknote) The banknote is sent to the banknote discharge unit 8 from the circulation transport path 3a through the connection transport path 3b as a "payment reject banknote". In addition, banknotes and the like that cannot be denominated by the identification sensor S are similarly sent to the banknote discharge unit 8 as “deposits rejected banknotes” and discharged to the outside from the outlet 14.

  Further, when there is a banknote that cannot be identified by the identification sensor S due to skew or the like among banknotes fed out from the storage unit 6, the banknote is connected and transported from the circulation transport path 3 a as a “withdrawal reject banknote”. It is sent to the withdrawal reject unit 4 through the path 3b.

(2) Passing Rate Control Operation Next, a specific example of the passing rate control operation by the control unit C (FIG. 2) will be described based on the flowchart of FIG. It is assumed that a target passing rate (for example, 99%) is set in advance by the passing rate setting means 11a. Further, it is assumed that a criterion value that seems to be lower than the target passing rate is initially set.

  First, when the apparatus is turned on, in step ST1, the control unit (arithmetic unit) C calculates a period passing rate from the previous power on to off (usually within one business day). Next, in step ST2, the control unit (passage rate control unit) C compares whether or not the calculated period passage rate has reached the target passage rate. As a result, when the period passage rate does not reach the target passage rate (step ST2 → YES), the determination reference value is increased by one step (0.5%) in step ST3. Then, the determination reference value is increased by one step (0.5%) each time the apparatus is turned on until the period passage rate reaches the target passage rate (step ST2 → NO) (step ST3). It will be.

[Function and effect]
Next, the effect of this embodiment comprised as mentioned above is demonstrated.

  According to the present embodiment, the control unit C simply gradually increases / decreases the determination reference value in a direction in which the period passing rate approaches the target passing rate, so that the operating passing rate gradually approaches the target passing rate. be able to. As a result, although a certain period of time may be required, it is possible to easily obtain a target passing rate considering both operational efficiency and consideration for the customer without performing complicated statistical processing or the like. In addition, since control is performed only with the resultant transmission rate as a target, it is possible to indirectly compensate for variations in sensitivity of the sensor S as a transmittance measuring unit and influences due to changes over time.

  Next, by setting the target passing rate by the passing rate setting means 11a, the balance between operational efficiency and customer consideration can be arbitrarily adjusted. In addition, the reference value adjusting means 11b can be used to directly adjust the determination reference value directly, so that the convenience of the administrator (user) can be improved. For example, in the pass rate control as described above, even if the setting of the target pass rate is changed to increase or decrease the pass rate, a pass rate close to the target pass rate cannot be obtained immediately. Therefore, the pass rate can be increased or decreased immediately by directly adjusting the determination reference value itself by the reference value adjusting means 11b.

[Modification]
(1) In the specific example of the pass rate control operation with reference to FIG. 3, generally, the determination reference value is gradually increased in consideration of a relatively high target pass rate (for example, about 99%). However, it is needless to say that this does not exclude the case where the criterion value is gradually decreased. That is, depending on the setting of the target passing rate and the determination reference value (initial value), the determination reference value may be gradually decreased, or gradually increased and gradually decreased.

  (2) It is also possible to stop the automatic passage rate control by the control unit (passage rate control unit) U described above and perform manual passage rate control only by adjusting the determination reference value by the reference value adjusting means 11b. It is.
