CONSTITUTION:A change discharging machine discharges the change amounts caused by the transaction processings (n11-n23) and also stores the largest number of dischargeable sheets for each denomination in a single change discharging processing. Then the change discharging machine decides the number of sheets that are discharged for each of denominations sucressively from the highest one to the lowest one based on the largest number of dischargeable sheets (n26-n52). Then the decided number of sheets are discharged for each denomination (n55).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a change dispenser for discharging change and the like generated by transaction processing.

[0002]

2. Description of the Related Art A change dispenser internally stores cash for each denomination, and discharges change and the like generated by transaction processing with this cash. At this time, the change dispenser calculates the number of cash to be discharged for each denomination in the combination that the total number of cash to be discharged is the minimum, and discharges it. If the calculated number of discharged coins is greater than the number of coins stored in any of the denominations, the change dispenser substitutes the deficiency by one lower denomination and discharges the deficiency. For example, when one 500-yen coin runs short, five 100-yen coins are used as substitutes for discharging.

[0003]

However, in the conventional change dispenser, when one denomination lower than the deficient denomination is also deficient, the denomination can be replaced with a further lower denomination and discharged. There wasn't. For example, if the 100-yen coin is also depleted when the 500-yen coin is depleted, it is not possible to substitute the 50-yen coin, which is one lower denomination, for the shortage of the 100-yen coin and release it. That is, one 500 yen coin
It was not possible to substitute four 100-yen coins and two 50-yen coins. Therefore, the change discharge has a drawback that the change discharge process cannot be performed in such a case.

In some stores, a specific denomination is not prepared as change due to cash management. In such a case, one specific denomination that is not one of the specific denominations that is not provided by the conventional change dispenser is placed. When the denomination is insufficient, the substitute emission cannot be performed in the change emission processing including the deficient denomination. For example, in a store that does not prepare 5000-yen banknotes as change, if 1000-yen banknotes are insufficient, alternative discharge cannot be performed. Further, when the denomination that is one rank higher than the specific denomination that is not prepared is insufficient, the substitute emission cannot be performed in the change emission processing including the deficient denomination. For example, 50
In a store that does not prepare 0-yen coins as change, if 1,000-yen banknotes are insufficient, alternative discharge cannot be performed. For this reason,
The conventional change dispenser has a drawback that the change discharge process cannot be performed frequently, and for the same reason, a free substitute such as a replacement of a 1000 yen bill with a 100 yen coin instead of a 500 yen coin. There was a drawback that the method could not be selected.

An object of the present invention is to enable, when one denomination to be released as change is in short supply, a process of substituting one denomination to the lowest denomination successively. An object of the present invention is to provide a change dispenser that can reduce the frequency at which change processing cannot be performed.

[0006]

DISCLOSURE OF THE INVENTION The change dispenser of the present invention is a discharge amount storage means for storing the amount of money to be released such as a change amount generated by transaction processing, and a storage currently stored inside the main body of the dispenser. A storing current number storage means for storing the current number of coins for each denomination, and the following processes (A) to (D) are repeated for each denomination from the highest denomination to the lowest denomination sequentially.
A denomination-specific number-of-discharges determining means for determining the number of denominations to be discharged for each denomination, and (A) a maximum number-of-discharges calculation process for calculating a maximum number of coins that does not exceed the amount of money to be released, The discharge number determination process in which the smaller number is compared with the maximum discharge number and the smaller one is the number to be actually discharged,
(C) Amount calculation process for calculating the amount of money to be actually discharged, (D) An amount obtained by subtracting the amount calculated in the amount calculation process from the amount to be discharged is updated as a new amount to be discharged. And a discharging means for discharging the number of moneys determined by the denomination-based discharge number determining means.

Further, the maximum number of releasable sheets inputting means for inputting the maximum number of sheets releasable by the releasing means for each denomination and the maximum releasable sheet number inputted by the maximum releasable sheet number input means are stored for each denomination. A maximum dischargeable number table, and the discharge number determination process is a process for adding the maximum dischargeable number to the current stored number and the maximum discharge number as a comparison target, and setting the minimum number of these as the discharge number. Is characterized in that.

[0008]

In the change dispenser of the present invention, the amount of change, such as the amount of change generated by the transaction process, is stored, and the current number of stored sheets for each denomination is stored. The change dispenser repeats the following processes (A) to (D) for each denomination from the highest denomination to the lowest denomination sequentially to determine the number of denominations to be released.

(A) The maximum number of sheets that can be discharged that does not exceed the amount of money to be discharged is calculated.

(B) The stored number and the maximum discharge number are compared, and the smaller number is set as the discharge number.

(C) The amount of money for the number of discharged sheets is calculated.

(D) The amount of money obtained by subtracting the amount of money calculated in (C) from the amount of money to be discharged is updated as the amount of money to be discharged.

Then, the change dispenser discharges the change by the number of discharges determined for each denomination.

With the above structure, the change dispenser substitutes the deficient amount of one lower denomination for the deficient amount that occurs when the current number of stored items is less than the maximum number, and this denomination is also insufficient. In this case, a lower denomination will be substituted. Therefore, when a certain denomination runs short, the change dispenser substitutes the deficient amount with a combination of denominations lower than the denomination to perform the change delivery processing.

Further, the change dispenser receives an input of the maximum number of releasable sheets for each denomination that can be released in the above-mentioned release process, and stores the input maximum number of releasable sheets for each denomination in the maximum releasable sheet number table. Then, the change dispenser sets the smallest one among the number of stored sheets, the maximum number of released sheets and the maximum number of deliverable sheets as the number of released sheets.

With the above configuration, for example, when the maximum number of 1-yen coins that can be discharged is set to 9,
When replacing one 50 yen coin, if the current number of 10 yen and 5 yen coins stored is 0, it will be replaced with 50 1 yen coins, which is not desirable for both the customer and the change dispenser. Can be prevented.

FIG. 5 is a diagram showing a register used for transaction processing of the change dispensing machine. The change dispenser 1 is a register that stores the current number of stored sheets C1 to C9 currently stored in the dispenser body for each denomination from 10,000 yen bill, which is the highest denomination, to 1 yen coin, which is the lowest denomination. Group (Fig. 5 (A))
And a group of registers for storing the number of discharged sheets N1 to N9 determined as the number of discharged sheets for each denomination from the 10,000-yen banknote which is the highest denomination to the 1-yen coin which is the lowest denomination at the time of transaction processing (see FIG. B)) and are provided in the memory 3. Further, in the memory 3, the transaction amount P to be used as a processing variable at the time of transaction processing, the deposit amount I, the amount to be released (discharging amount) O such as the change amount, the current stored number C, the maximum number of deliverable sheets. Areas for storing M, denomination U, number of ejected sheets N, and number buffer d are allocated (FIG. 5C).

FIG. 6 is a diagram showing a flow of transaction processing operation of the change dispenser. FIG. 7: is a figure which shows the operation example of the transaction processing operation of a change dispenser, and the display example of a display part.

First, when the transaction key is operated on the keyboard 6, it is determined in n2 (see FIG. 3) that the input key is the transaction key, and the display section 7 displays "price?" (N1).
1). The change dispenser 1 waits in a state of waiting for an input from the keyboard 6 (n12). When there is a key input, the change dispenser 1 determines whether the input key is a set key (n1
3) If it is not the set key, it is determined whether it is a numeric key (n14). At this time, if it is determined that it is a numeric key,
The change dispenser 1 writes the data for the input numeric key in the numeral buffer d (n15), and again the keyboard 6
It waits for the key input from (n12). On the other hand, n1
If it is determined in step 4 that the key is not a numeric key, error processing is performed (n16) and the transaction processing ends. When it is determined in n13 that the input key is the set key, the contents of the number buffer d are written in the transaction amount P (n17).

The above-mentioned processing of n12 to n15 is a transaction amount input operation, in which the transaction amount input by the operation of the numeric keys is temporarily stored in the numeral buffer d, and the set key is pressed, and then the processing variable. In the transaction amount P of
The value of is written. As a result, the change dispenser 1
The transaction amount generated by transaction processing is set.
For example, when the transaction amount is 1758 yen, the operator operates the keys in the order of 1, 7, 5, 8 and set to input. At this time, the change dispenser 1 has 1 in the number buffer d,
7, 5 and 8 are temporarily stored, and 1758 stored in this numerical input buffer d is written into the transaction amount P by operating the set key.

Next, the change dispenser 1 displays the value of P and "please deposit money" on the display unit 7 (n1
8), stand by in the waiting state for depositing bills and coins (n1
9).

The change dispenser 1 calculates the deposit amount deposited by the operator through the coin deposit port 4a and the bill deposit port 5a in the coin processing unit 4 and the bill processing unit 5, and writes it in the deposit amount I (n20). The change dispenser 1 compares the transaction amount P with the deposit amount I (n21), performs error processing when the transaction amount P is larger than the deposit amount I (n22), and ends the transaction process.

When the transaction amount P is less than the deposit amount I, the change dispenser 1 writes the value obtained by subtracting the transaction amount P from the deposit amount I into the release amount O as the amount to be released (n
23), the content of the amount of release O is displayed on the display unit 7 (n2
4). For example, when the transaction amount is 1758 yen and the deposited amount is 2008 yen, the change dispenser 1 displays on the display unit 7.
“Change ¥ 250” is displayed on the screen.

Then, it is judged whether or not the released amount O is 0 (n25), and when the released amount O is 0, the display of the display unit 7 is cleared after a certain period of time (n57) to end the transaction processing operation. When the release amount O is not 0, the highest denomination of 10,000 yen is selected as the release number determination denomination for first determining the release number, and the contents of the 10,000-yen banknote storage current number C1 are stored as the denomination-based current number. The value is read from the storage register and is written in the current number of stored sheets C, the maximum number M1 of 10,000-yen banknotes that can be discharged is read from the maximum number of dischargeable sheets table and is written in the maximum number of dischargeable sheets M, and the unit price 10000 of the number of discharged money determination denomination U (N26). Then, the process proceeds to a subroutine for determining the number of discharged sheets (n27).

FIG. 8 is a diagram showing a flow of the discharge number determination serve routine operation. First, the release amount O is divided by the denomination U, and the integer value of the result is written in the release number N (n61). Reference numeral n61 is the discharge number calculation processing of the present invention, and the numerical value written in the discharge number N at this time is the maximum discharge number of the present invention. Then, the number N of discharged sheets and the maximum number M of releasable sheets are compared (n62), and when the number of discharged sheets N> the maximum number of releasable sheets M, the maximum number of releasable sheets M is substituted for the number of discharged sheets N (n63). As a result, the maximum number M of sheets that can be discharged becomes the number of discharged sheets N, and the change dispenser 1 compares the number of discharged sheets N with the current number of stored sheets C (n64). In N62, when N ≦ M, the process of substituting for the number of discharged sheets N is not performed, and the number of discharged sheets N is compared with the current number of stored sheets C (n6).
4). When the number of discharged sheets N> the current number of stored sheets C, the current number of stored sheets C is substituted for the number of discharged sheets N (n65). As a result, the current stored number C becomes the discharged number N. On the other hand, when the number of discharged sheets N ≦ the current number of stored sheets C, the change dispenser 1 does not substitute the number of discharged sheets N. n62 to n65 are
This is the process for determining the number of discharged sheets according to the present invention.

That is, the change dispenser 1 compares three of the maximum number of discharges set, the maximum number of discharges N, the maximum number of dischargeable sheets M, and the current number of stored sheets C, and stores the smallest number as the number of discharged sheets N. Then, the change dispenser 1 substitutes the result obtained by subtracting the product of the denomination U and the number of released sheets N from the released amount of money O into the released amount of money O (n66), and ends the released number determination subroutine.
Reference numeral n66 is the amount calculation process and the released amount update process of the present invention, in which the change dispenser 1 calculates the shortage amount with respect to the released amount when the release number determination denomination is released with the determined released number, and the shortage amount is calculated. Is updated as a new release amount. For example, if the amount released is 250 yen, 1
The number of discharged 10,000-yen banknotes is determined to be 0, and the updated discharged amount is 250 yen. Also, the amount released is 1234
In the case of 5 yen, when the number of discharged 10,000-yen banknotes is determined to be 1, the discharged amount is updated to 2345 yen.

When the n27 subroutine is completed,
The value of the number of discharged sheets N determined by the subroutine for determining the number of discharged sheets is substituted for the number N1 of discharged 10,000 yen bills in the discharged number storage register (n28). In other words, the number N1 of 10,000-yen banknotes to be discharged in the discharged number memory register has been determined.

Next, 5000 yen, which is one lower denomination of 10,000 yen, which is the highest denomination, is selected as the denomination for determining the number of ejected coins, and the above processing is performed to determine the number N2 of 5000-yen banknotes to be ejected. (N29 to n31). Then, the number of discharged sheets is determined for each denomination from the highest denomination to the lowest denomination. That is, the change dispenser 1 uses 1000-yen bills (n32 to n3).
4), 500 yen coins (n35 to n37), 100 yen coins (n38 to n40), 50 yen coins (n41 to n43),
10 yen coins (n44 to n46), 5 yen coins (n47 to n)
49) The number of discharged coins is sequentially determined up to 1-yen coins (n50 to n52), and the number of discharged coins N3 to N9 is written for each denomination in the discharged coin number storage register.

Subsequently, it is determined whether the amount of money O to be released is 0 (n53), and if it is not 0, error processing is performed (n5).
4), end the transaction processing operation. On the other hand, the release amount O is 0
In this case, the change dispenser 1 uses the coin processing unit 4 and the banknote processing unit 5 to transfer the number of discharged sheets N1 to N9 set in the discharged number register for each denomination from the coin outlet 4b and the banknote outlet 5b. Release (n55). After the discharge processing is completed, the change dispenser 1 updates the current storage number register with the number of discharged sheets N1 to N9 (n56), waits for a certain period of time, clears the display on the display unit 7 (n57), and ends the transaction processing operation. .

With the above configuration, when the change denomination machine 1 runs short of a specific denomination when releasing the change, the denominations of lower ranks sequentially substitute the deficient amount. . For example, if one 500-yen coin runs short, and five 100-yen coins, one of the lower denominations, can be used for replacement, five 100-yen coins will be used for replacement, and one 100-yen coin will also be used. If you run out of coins, it is one lower denomination, 50
It is judged whether or not two yen coins can be discharged, and the shortage of one 100 yen coin is replaced with two 50 yen coins to discharge.
That is, in such a case, the change dispenser 1 can replace one 500-yen coin with four 100-yen coins and two 50-yen coins.

FIG. 9 is a diagram showing a flow of the setting processing operation of the change dispenser. FIG. 10 is a diagram illustrating an operation example of a setting processing operation of the change dispenser. When the setting key of the keyboard 6 is operated, the change dispenser 1 determines that the input key is the setting key at n4, and starts the setting processing operation (n5). The change dispenser 1 displays “1 yen number?” On the display unit 7 (n6
1), a numerical input subroutine is executed (n62).

FIG. 11 is a diagram showing the processing of the numerical input subroutine. The change dispenser 1 waits for input from the keyboard 6 (n100), determines whether the input key is a set key when there is input from the keyboard (n101), and when it is not the set key. Determines whether it is a numeric key (n102). At this time, if it is determined that it is a numeric key, the change dispenser 1 writes the data corresponding to the input numeric key in the numeral buffer d (n103), and waits again for a key input from the keyboard 6 (n10).
0). If it is determined in n102 that the key is not the numeric key, error processing is performed (n104), and the setting processing ends. n10
When it is determined in 1 that the input key is the set key, the numeral input subroutine is ended, and the contents of the numeral buffer d are written in the maximum dischargeable number M9 of 1-yen coins (n63). That is, the process of n100 to n103 is a process of setting the maximum number of releasable sheets M1 to M9, the operator operates the number keys to input the maximum number of releasable sheets, and presses the set key. For example, when setting the maximum number of 1-yen coins that can be discharged to 9, the keys are operated in the order of 9 and set.

Subsequently, the change dispenser 1 displays "5 yen coins?" On the display unit 7 (n64), performs the above-mentioned numeral input subroutine (n65), and changes the contents of the numeral buffer d to 5 yen coins. (N66). The change dispenser 1 repeats this process sequentially from the lower denomination to the uppermost denomination, 10 yen coins (n67 to n69), 50 yen coins (n70 to n72), 100 yen coins (n73 to n7).
5), 500 yen coins (n76 to n78), 1000 yen banknotes (n79 to n81), 5000 yen banknotes (n82 to n8)
4) The maximum number of releasable sheets up to 10,000 yen bills (n85 to n87) is set. As a result, the change dispenser 1 stores in the memory 3 the maximum dischargeable number table in which the maximum dischargeable numbers M1 to M9 for each denomination are set.

Then, the change dispenser 1 displays "setting completed" on the display unit 7 (n88), waits for several seconds to clear the display (n89), and completes the setting processing operation.

With the above-mentioned structure, the maximum number of coins to be released when releasing change or the like can be set for each denomination. As a result, for example, when the 5000 yen bill is not used as change, the maximum dischargeable number is set to 0, and the 5000 yen bill is skipped to 100.
It is possible to substitute and release 0 yen bills and the like, and in consideration of convenience of cash management in a store, it is possible to freely set a denomination that is not used as change. Further, for example, if the setting of the maximum number of 1-yen coins that can be discharged is 9, and when the replacement of 1 50-yen coin is performed and the current number of 10-yen and 5-yen coins stored is 0, It is replaced by 50 coins of 1 yen, is not released, and it is possible to prevent deterioration of service to customers.

In the above embodiment, the change dispenser provided with the depositing means has been described, but the present invention can be similarly applied to a change dispenser having no depositing means. Also, the description has been given for each denomination from 1-yen coin to 10000-yen bill, but it can be applied by increasing the denomination type by 1 even when a 50,000-yen bill or the like is issued in the future. it can. Furthermore, after determining the number of released coins for each denomination, it is determined whether or not the updated amount of released coins is 0, and if it is 0, the process of determining the number of ejected coins for a denomination lower than this denomination is not performed. May be subjected to a release treatment.

[0040]

As described above, according to the present invention, when the change dispenser runs short of a specific denomination, it is replaced by one lower denomination, and further when this denomination runs short. 1
Subsequent denominations and lower denominations will be replaced in turn. For this reason, the change dispenser can perform alternative discharge when a certain denomination is insufficient and even if one denomination lower than this denomination is insufficient. Also, since the maximum number of denominations that can be released can be set for each denomination, by setting the denomination that is not prepared as change to 0, it is possible to jump over this denomination and perform alternative release. The frequency with which processing cannot be performed can be reduced. Further, it is possible to prevent deterioration of service to customers such as replacement of 50 yen by 50 coins of 1 yen.
