Description

  The present invention relates to a merchandise sales data processing apparatus such as a POS (Point Of Sales) terminal for connecting a money depositing / withdrawing apparatus capable of depositing and withdrawing money and withdrawing a change in a commercial transaction from the money depositing / withdrawing apparatus.

  In recent years, a payment system has been developed in which a money depositing / withdrawing apparatus is connected to a POS terminal, and a change in merchandise transactions for which product sales data has been processed by this POS terminal is automatically withdrawn from the money depositing / withdrawing apparatus, such as a supermarket. Already in practical use. The money depositing / withdrawing device used in this type of settlement system includes a function for selecting money inserted into the money input unit and storing it in a hangar according to the denomination, and change amount data given from the POS terminal. In addition to the function of extracting the corresponding money from the hangar and discharging it to the money discharging unit, this type has the function of counting the money input into the money input unit and supplying the input money amount data to the POS terminal. There is. When this type of money depositing / withdrawing device is used, the POS terminal uses the deposit amount data taken from the money depositing / withdrawing device as the deposit amount, calculates the change amount from this deposit amount and the amount charged for the transaction, and changes the change amount. Is greater than 0, that is, when change is required, the change amount data is controlled to be provided to the money depositing / dispensing apparatus. Therefore, the cashier only has to put the money that the customer paid for the purchased goods into the money input part of the money depositing / dispensing device, and the money deposited from the customer is counted and the deposit amount is stored in the POS terminal. There is no need for input (for example, see Patent Document 1).

  By the way, in a commercial transaction with a customer, there is a case where an additional deposit is given from the customer immediately before the cashier delivers the change dispensed from the money depositing / withdrawing device to the customer. For example, when a customer pays 1000 yen for a business transaction with an invoiced amount of 915 yen, deposits it into a money depositing / withdrawing device, and then changes 85 yen, then the customer receives 15 yen as a fraction. is there.

  In this case, the customer expects a change of one 100 yen coin. However, in this type of settlement system that is currently in operation, it has been impossible to withdraw changes again from the money deposit / withdrawal device for one transaction. For this reason, the cashier had to take a 100-yen coin from the change reserve prepared separately and give it to the customer. Moreover, since 85 yen withdrawn from the money depositing / withdrawing apparatus and 15 yen received from the customer cannot be deposited into the money depositing / withdrawing apparatus, they had to be managed separately. For this reason, there was a problem that handling of money became complicated.

In addition, the applicant of the present application operates a key for commanding recalculation of change and inputs an additional deposit amount after depositing money corresponding to the change amount of one commercial transaction from the money depositing and dispensing device. Then, an additional deposit amount was added to the change amount of the one business transaction to obtain a change amount after recalculation, and the money corresponding to the change amount after the recalculation was withdrawn again from the money deposit / withdrawal device. A product sales data processing device has been proposed (see, for example, Patent Document 2).
Japanese Patent No. 3308244 JP-A-8-171676

  As described above, in a conventional merchandise sales data processing apparatus using a money deposit / withdrawal apparatus that does not require a deposit amount, change can be withdrawn again from the money deposit / withdrawal apparatus for a single commercial transaction. Since it was not possible, after the change was withdrawn, there was a problem that handling of money would be complicated when a fraction of the billed amount was presented again by the customer. Such a problem cannot be solved even by the prior art proposed by the applicant of the present application, in which a change can be recalculated by inputting an additional deposit amount.

  The present invention has been made based on such circumstances. The purpose of the present invention is that even if an additional deposit is received from the customer after the change has been withdrawn from the money depositing / withdrawing apparatus, It is an object of the present invention to provide a merchandise sales data processing apparatus capable of withdrawing changes recalculated from a money depositing / withdrawing apparatus without complicated handling.

  The present invention is a commodities sales data processing device that processes sales data of products sold and sold in a commercial transaction with a customer and calculates and outputs a billed amount of the commercial transaction, for example, a POS terminal so that a money deposit / withdrawal device is communicably connected Connecting means, a change calculating means for calculating a change amount from a deposit amount deposited in the money depositing / withdrawing apparatus and a billing amount of a commercial transaction, and a money corresponding to the change amount calculated by the change calculating means And a change recalculation instruction means for instructing a recalculation of change for a business transaction in which the change has been withdrawn by the change withdrawal control means, and a change recalculation instruction means for After the calculation is instructed, when money is deposited in the money depositing / withdrawing device, it is provided with a re-cash dispensing control means for withdrawing money corresponding to the deposited amount from the money depositing / withdrawing device. It is intended.

  In the present invention in which such a measure is taken, when an additional deposit is given from the customer after the change has been withdrawn from the money depositing / withdrawing apparatus, the cashier has instructed the change recalculation by the change recalculation instruction means. After that, the changed change and the additional deposit are put together into the money deposit / withdrawal apparatus. Then, since money corresponding to the deposit amount is withdrawn from the money deposit / withdrawal device, the cashier delivers the dispensed money to the customer as change. Therefore, it is not necessary to prepare the money necessary for the change from the separately prepared change reserve. Moreover, both the money equivalent to the change amount withdrawn before the change recalculation from the money deposit / withdrawal apparatus and the money deposited as an additional deposit from the customer are deposited into the money deposit / withdrawal apparatus. Therefore, there is no need to manage these currencies separately.

  Therefore, according to the present invention, even when an additional deposit is handed over from the customer after the change has been withdrawn from the money deposit / withdrawal device, the recalculated change in the money deposit / withdrawal is made without complicating the handling of the money. It is possible to provide a merchandise sales data processing apparatus that can withdraw money from a gold apparatus and improve workability of accounting work.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing a payment system according to the present embodiment. This payment system includes a POS terminal 1 and a money depositing / withdrawing apparatus 2. The money depositing / withdrawing apparatus 2 includes a banknote change machine 3 that deposits and withdraws banknotes, and a coin change machine 4 that deposits and withdraws coins. The POS terminal 1, the banknote change machine 3, and the coin change machine 4 are connected to each other via an interface so that they can communicate with each other.

  The banknote change machine 3 collects and sorts banknotes inserted into the banknote input unit 31 and stores them in a banknote storage (not shown) according to denomination, and a change dispensing command from the POS terminal 1. And a withdrawal function for extracting necessary banknotes from the banknote storage and discharging them to the banknote discharge unit 32. In addition, it has a reject function for discharging banknotes that could not be sorted out from the banknote discharge unit 32 and issuing a warning from the display unit 33.

  The coin changer 4 collects and sorts coins input to the coin input unit 41 in a lump and stores them in a coin storage (not shown) according to denomination, and in response to a change dispensing command from the POS terminal 1. And a withdrawal function for extracting necessary coins from the coin storage and discharging them to the coin discharge unit 42. In addition, it has a reject function of discharging a coin that could not be sorted out from the coin discharge unit 42 and issuing a warning from the display unit 43.

  The POS terminal 1 is an aspect of a merchandise sales data processing apparatus according to the present invention. Data obtained by mounting input / output devices such as a keyboard 11, an operator display 12, a customer display 13, and a receipt printer 14 on the main body 10. It is a processing terminal. The principal part structure of the POS terminal main body 10 is shown with the block diagram of FIG.

  As shown in the figure, the POS terminal main body 10 includes a CPU (Central Processing Unit) 51 constituting a main control unit, a ROM (Read Only Memory) 52 in which fixed data such as programs are stored in advance, and merchandise sales data processing. Random Access Memory (RAM) 53 in which various necessary memory areas are formed, an electronic journal file 54 for electronically storing and storing journal data, a clock unit 55 for measuring the current date and time, a wired or wireless communication line In addition to a communication controller 56 for controlling data communication with a higher-level store computer connected via a scanner, a scanner interface 57 to which a scanner for reading bar codes and the like is connected, and key input of the keyboard 11 are controlled. Keyboard controller 58 for controlling the screen display of the operator display 12. A first display controller 59, a second display controller 60 for controlling the screen display of the customer display 13, a printer controller 61 for controlling a receipt printing and receipt issuing operation of the receipt printer 14, and the banknote change machine 3 The coin change machine 4 is configured by a change machine interface 62 or the like as connection means for connecting the coin change machines 4 so as to communicate with each other.

  The CPU 51, the ROM 52, the RAM 53, the electronic journal file 54, the clock unit 55, the communication controller 56, the scanner interface 57, the change machine interface 62, and the controllers 58 to 61 of the various input / output devices 11 to 14, an address bus, a data bus, etc. Are connected by a bus line 63.

  As shown in FIG. 3, the keyboard 11 includes a numeric key 71 for inputting numeric data, a multiplication key 72, a clear key 73, a subtotal key 74, a deposit / cash key 75, and a cancel key. Various function keys such as 76, a deposit confirmation key 77, a confirmation key 78, and a fishing recalculation key 79 are arranged. The deposit / current total key 75 is a key for declaring closing of one commercial transaction. The deposit confirmation key 77 is used to deposit money, which is a deposit paid by a customer for the amount charged for one commerce transaction, into the money depositing / dispensing apparatus 2, that is, at least one of the bill changer 3 and the coin changer 4. The confirmation key 78 is a key for instructing that the deposit money is deposited into at least one of the banknote change machine 3 and the coin change machine 4. The change recalculation key 79 is a key as change change calculation instruction means for instructing change recalculation of a commercial transaction in which change has been dispensed.

  In the RAM 53, as shown in FIG. 4 in particular, a transaction date area, a transaction number area, a transaction time area, a casher name area, a plurality of purchased product details data area, a deposit input amount area, a manually input amount area, a total deposit amount area , A transaction processing memory 80 having a billing amount area and a change amount area is formed.

  Therefore, the CPU 51 controls each part in accordance with the procedure shown in the flowchart of FIG. 5 for a commercial transaction with one customer. First, the CPU 51 waits for registration of a product to be bought and sold in a commercial transaction with a customer as ST (step) 1. Here, for example, when a barcode (product code) attached to a product is read by a scanner connected to the scanner interface 57, it is determined that the product is registered. Then, the CPU 51 refers to the registering flag as ST2, and determines whether or not the product for one commercial transaction is being registered. Initially, since the registration flag is reset to “0” and the product is not being registered, the CPU 51 initializes each area of the transaction processing memory 80 as ST3. At this time, the current date and time measured by the clock unit 55 are set in the transaction date area and the transaction time area. The latest transaction number is set in the transaction number area. The name of the cashier who signed on is set in the cashier name area. All other areas are cleared to “0”.

  Next, after setting the registering flag to “1” as ST4, the CPU 51 performs merchandise sales data processing as ST5. That is, a product data file prepared in advance with the input product code is searched, and the unit price, product name, etc. preset corresponding to the product code are called. Then, if the sales amount is calculated by multiplying the unit price by the sales point (the multiplier when the multiplier key 72 and the multiplication key 72 are input immediately before, the multiplier when the multiplier is not input, or 1). For example, item data such as a product code, a product name, a unit price, a sales point, and a sales price is stored in the transaction processing memory 80 as purchased product detail data. Also, the product name, unit price, number of sales points, sales price, etc. are displayed on the operator display 12 and the customer display 13.

  Thereafter, the CPU 51 determines whether or not the deposit confirmation key 77 is operated in ST6. If the deposit confirmation key 77 is not operated, the process returns to ST1 and waits for the next product registration. When the next product registration is performed, since the registration flag is already set, the CPU 51 immediately executes the product sales data process of ST5.

  When it is detected in ST6 that the deposit confirmation key 77 is operated by an input signal to the keyboard controller 58, the CPU 51 confirms the deposit confirmation of the layout shown in FIG. 7 on the operator display 12 and the customer display 13 as ST7. A screen 90 is displayed. Then, if the billing amount of the one commercial transaction is calculated based on the purchased merchandise item data stored in the transaction processing memory 80, the billing amount is displayed in the billing amount area 91 of the payment confirmation screen 90. In ST8, a command for preparing a deposit command is transmitted to the bill change machine 3 and the coin change machine 4 via the change machine interface 62 to notify that money is deposited.

  The banknote change machine 3 that has received this deposit preparation command command waits for a banknote to be inserted into the banknote insertion unit 31. And if a banknote is thrown in, the banknote will be taken in and collected collectively, and will be accommodated in a banknote storage by denomination. In addition, the total amount of bills inserted is counted. Similarly, the coin change machine 4 that has received the command waits for a coin to be inserted into the coin insertion unit 41. And if a coin is thrown in, the coin will be taken in and selected collectively, and will be accommodated in a coin storage by denomination. The total amount of coins entered is counted.

  After sending the command for deposit preparation command, the CPU 51 waits for the confirmation key 78 to be operated as ST9. When it is detected by the input signal to the keyboard controller 58 that the confirmation key 78 has been operated, the CPU 51 uses the bill insertion amount and the coin change machine 4 counted in the bill change machine 3 as ST10. Take in the amount of coin input that has been accounted for. When the deposit input amount is calculated by adding the bill input amount and the coin input amount as ST11, the deposit input amount is stored in the deposit input amount area of the transaction processing memory 80, and the deposit confirmation screen 90 is displayed. It is displayed in the deposit input amount area 92. In ST12, the total deposit amount is calculated by adding the deposit amount in the deposit amount area in the transaction processing memory 80 and the manually input amount in the manual amount area. The total deposit amount is stored in the total deposit amount area of the transaction processing memory 80 and displayed in the total deposit amount area 93 on the payment confirmation screen 90.

  Next, the CPU 51 determines whether or not the enter key 78 has been operated after the numerical data is entered using the numeric key 71 in ST13. If the operation of the numeric key 71 and the enter key 78 is detected by the input signal to the keyboard controller 58, the CPU 51 manually inputs the transaction data 80 in ST14 using the numeric data as a manual input amount in ST14. The information is stored in the area and displayed in the manually input amount area 94 on the payment confirmation screen 90. After that, the process returns to ST11, and the total deposit amount is recalculated to rewrite the deposit total amount area data in the transaction processing memory 80, and the amount in the total deposit amount area 93 on the deposit confirmation screen 90 is updated.

  If the combination operation of the numeric key 71 and the confirmation key 78 is not performed in ST12, the CPU 51 determines whether or not the deposit / cash key 75 is operated in ST15. When the operation of the deposit / cash total key 75 is detected by an input signal to the keyboard controller 58, the CPU 51 stores the bill amount and the deposit total amount stored in the bill amount area of the transaction processing memory 80 as ST16. Compare the total amount stored in the area. If the total deposit amount is equal to or greater than the billing amount, the settlement of the commercial transaction is established, and the CPU 51 calculates the change amount by subtracting the billing amount from the total deposit amount (ST17). . Then, the change amount is stored in the change amount area of the transaction processing memory 80.

  Next, CPU51 judges whether the amount of change is larger than 0 yen as ST18. And since it is necessary to pay change when it is larger than 0 yen, CPU51 sends the command of change payment command to the bill change machine 3 and the coin change machine 4 via the change machine interface 62 as ST19, Withdraw money corresponding to the change amount (change change control means).

  Thereafter, the CPU 51 edits the receipt print data based on the data of each item stored in the transaction processing memory 80 as ST20. Then, the receipt print data is output to the receipt printer 14 and, as shown in FIG. 8, a commercial transaction receipt 100 on which purchased merchandise details data, total amount, total deposit amount, change amount, etc. are printed is issued (normal receipt) Issuing means). In ST21, the journal data corresponding to the receipt print data is edited and stored in the electronic journal file 54. Thereafter, the CPU 51 resets the registering flag to “0” in ST22, and ends all the controls for the current commercial transaction. The payment confirmation screen 90 is displayed until product registration for the next commercial transaction is started.

  Further, when the fishing recalculation key 79 is operated, the CPU 51 controls each part according to the procedure shown in the flowchart of FIG. First, the CPU 51 determines whether or not a registration flag is set in ST31. Here, when the registering flag is set, it is an erroneous operation in which change recalculation is instructed during the processing of one commercial transaction, so the CPU 51 makes an operation of the change recalculation key 79 an error.

  On the other hand, when the registering flag is reset, change recalculation is instructed after the processing of one commercial transaction is completed, so the CPU 51 changes the change stored in the change amount area of the transaction processing memory 80 as ST32. It is determined whether or not the amount is larger than 0 yen (change determination means). Here, if the change amount is 0 yen, it is an erroneous operation in which change recalculation has been instructed for a commercial transaction for which change has not been withdrawn, so the CPU 51 makes an operation of the change recalculation key 79 an error. .

  On the other hand, when the change amount is larger than 0 yen, the change recalculation is instructed for the commercial transaction immediately before the change is withdrawn, so the CPU 51 determines the bill change machine 3 via the change machine interface 62 as ST33. And the command of a deposit preparation command is transmitted to the coin change machine 4, and it is notified that money is deposited.

  Thereafter, the CPU 51 waits for the confirmation key 78 to be operated in ST34. When it is detected that the confirmation key 78 is operated by an input signal to the keyboard controller 58, the CPU 51 uses the bill insertion amount counted in the bill change machine 3 and the coin change machine 4 as ST35. Take in the amount of coin input that has been accounted for. Then, in ST36, when the amount of money inserted is calculated by adding the amount of money inserted into the coin and the amount of money inserted in the coin, the amount of change stored in the change amount area of the transaction processing memory 80 is subtracted from this amount of money to be additionally deposited. Calculate the amount (additional deposit amount calculation means).

  If it is confirmed in ST37 that the additional deposit amount is larger than 0 yen, the CPU 51 adds the additional deposit amount to the total deposit amount stored in the deposit total amount area of the transaction processing memory 80 in ST38. To do. Then, the change amount is recalculated by subtracting the charge amount stored in the charge amount area of the transaction processing memory 80 from the total deposit amount after addition of the additional deposit amount (change recalculation means). Then, the change amount stored in the change amount area of the transaction processing memory 80 is updated to the amount after recalculation.

  Next, CPU51 judges whether the amount of change is larger than 0 yen as ST40. And since it is necessary to pay change when it is larger than 0 yen, CPU51 sends the command of change payment command to the bill change machine 3 and the coin change machine 4 via the change machine interface 62 as ST41, Money corresponding to the amount of change is withdrawn (re-change money withdrawal control means).

  Thereafter, the CPU 51 edits the receipt print data again based on the data of each item stored in the transaction processing memory 80 as ST42. Then, the receipt print data is output to the receipt printer 14 and, as shown in FIG. 9, the change recalculation receipt on which the recalculated total deposit amount, change amount, etc. are printed together with the purchase item description data and the total amount. 110 is issued (change recalculation receipt issuing means). In addition, as in the record example of the electronic journal file 54 shown in FIG. 10, the journal data 111 including the phrase “change recalculation” and the additional deposit amount is edited and saved in the electronic journal file 54, and this control is performed. Exit.

  In a store such as a supermarket in which the payment system of the present embodiment configured as described above is introduced, when a cashier receives an offer for accounting for a purchased product from a customer, first, a scanner connected to the POS terminal 1 is installed. Operate to register the purchased product in the POS terminal 1. When the registration is completed, the deposit confirmation key 77 is operated. Then, the charge amount for the purchased product is calculated and displayed in the charge amount area 91 of the payment confirmation screen 90 on the operator display 12 and the customer display 13.

  Therefore, the cashier receives a payment from the shopper corresponding to the amount charged. Then, if money such as banknotes or coins is deposited as a payment from the shopper, the banknotes are inserted into the banknote insertion unit 31 of the banknote changer 3, and the coins are inserted into the coin insertion unit 41 of the coin changer 4, respectively. The key 78 is operated.

  Then, the bill change machine 3 counts the total amount of bills inserted into the bill insertion unit 31, so-called bill insertion amount, and the coin change machine 4 calculates the total amount of coins inserted into the coin insertion unit 41, so-called coin insertion amount. Is counted. Thus, in the POS terminal 1, the deposit amount is calculated by adding the bill insertion amount and the coin insertion amount, and is displayed in the deposit amount area 92 on the deposit confirmation screen 90. The total deposit amount is calculated by adding the deposit input amount and the manually input amount, and is displayed in the total deposit amount area 93 on the deposit confirmation screen 90. The manually input amount is initially 0 yen. For example, when a bill inserted into the bill change machine 3 is rejected without being sorted, after the amount of the bill is placed with the placement key 71, the confirmation key 78 is entered. Is processed as a manually input amount of deposit, and is displayed in the manually input amount area 94.

  When the cashier determines that the total deposit amount is equal to or greater than the billing amount and can be settled, the cashier operates the deposit / current total key 75 to declare the closing of one commercial transaction. Then, the POS terminal 1 calculates the change amount by subtracting the charge amount from the total deposit amount. Here, when the change amount is larger than 0 yen, a change amount payout command is transmitted to the banknote change machine 3 and the coin change machine 4. Thereby, the change of the banknote is discharged from the banknote change machine 3 to the banknote discharge unit 32, and the change of the coin is discharged from the coin change machine 4 to the coin discharge unit 42. In addition, a commercial transaction receipt 100 is issued on which product details data, total amount, total deposit amount, change amount, etc. are printed.

  For example, suppose that a shopper who has purchased two items, a product AAAA with a unit price of 525 yen and a product BBBB with a unit price of 390 yen, paid for the 915 yen with a thousand yen bill. Then, after registering the product AAAA and the product BBBB in the POS terminal 1, the cashier operates the deposit confirmation key 77 and then inserts the thousand-yen bill into the bill insertion unit 31 of the bill changer 3 and operates the confirmation key 78. To do. Then, the charged amount of 915 yen is subtracted from the total deposit amount of 1000 yen to calculate a change amount of 85 yen, and a change payout command for the change amount of 85 yen is transmitted to the banknote change machine 3 and the coin change machine 4. As a result, normally, a total of 85 yen including one 50 yen coin, three 10 yen coins and one 5 yen coin is paid out as change from the coin change machine 4. Further, a commercial transaction receipt 100 having the contents shown in FIG. 8 is printed and issued. Therefore, the cashier gives the receipt 100 to the customer together with the change coin of 85 yen in total, and ends the commercial transaction with the customer.

  By the way, after the change of 85 yen is paid out, the shopper may be given 15 yen, which is a fraction of the price. In this case, the cashier operates the fishing recalculation key 79 and then collects the 85 yen coins paid out from the coin change machine 4 and the 15 yen coins deposited from the customer into the coins of the coin change machine 4. Input into the input unit 41. After the insertion, the confirmation key 78 is operated. Then, the inserted coin is counted, and the data of the input amount 100 yen is taken into the POS terminal 1. In the POS terminal 1, the change amount of 85 yen already paid out is subtracted from the input amount of 100 yen to calculate an additional deposit amount of 15 yen, and the total deposit amount is updated to 1015 yen. Further, the charged amount of 915 yen is subtracted from the total deposit amount of 1015 yen, and the change amount of 100 yen is recalculated.

  Thus, a change dispensing instruction with a change amount of 100 yen is output to the banknote change machine 3 and the coin change machine 4, and one 100 yen coin is discharged from the coin change machine 4. Further, as shown in FIG. 9, a change recalculation receipt 110 in which the recalculated total deposit amount of 1015 yen and the change amount of 100 yen are printed is issued. Therefore, the cashier discards the commercial transaction receipt 100 that has already been issued, and instead passes the change recalculation receipt 110 and the change 100 yen to the customer, and ends the commercial transaction with the customer.

  As described above, according to the present embodiment, even when the change is withdrawn from the customer, for example, even when the fraction of the billing amount is presented again, the change amount is automatically re-established with the deposit amount including the additional amount. Since the money corresponding to the calculated change amount is withdrawn from the money deposit / withdrawal device 2, there is no need to arrange the change from a separately prepared change reserve and hand it to the customer. In addition, since the money withdrawn as change from the money deposit / withdrawal device 2 and the money deposited as additional deposit from the customer are collected together into the money deposit / withdrawal device 2 before recalculation of change, There is no need for separate management. Therefore, handling of money becomes easy, and the workability of accounting work can be improved.

  Further, in the present embodiment, it is determined whether or not change recalculation is instructed for a business transaction in which change has been withdrawn, and re-change control is permitted only for a business transaction in which change has been withdrawn. Therefore, it is possible to prevent the trouble that the change is recalculated for the business transaction in which there is no change.

  Further, in the present embodiment, when a deposit is added, a change recalculation receipt 110 with the contents after the deposit is added is issued, so that it matches the actual payment amount and change to the shopper. You can give a receipt. In this case, the change recalculation receipt 110 can be distinguished from the previously issued commercial transaction receipt 100 by, for example, printing the phrase “change change recalculation”.

  Further, by recording the phrase “change recalculation” in the journal data, it is possible to identify the business transaction for which the change has been recalculated by confirming the journal data later.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the change recalculation receipt 110 is printed and issued. However, the present invention includes one that does not have the function of printing and issuing the change recalculation receipt 110.

  Moreover, in the said embodiment, although the banknote change machine 3 and the coin change machine 4 were connected in parallel to the change machine interface 62, the banknote change machine 3 was connected to the change machine interface 62, and a coin change machine was connected to the banknote change machine 3. By connecting 4, the bill change machine 3 and the coin change machine 4 may be connected in series.

  Further, the change recalculation instruction means is not limited to the change recalculation key 79 on the keyboard 11. For example, when a touch panel is used as the operator display 12, a GUI (Graphical User) displayed on the touch panel is used. One of the (Interface) buttons may be used as a change recalculation instruction means.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
