  The POS register device 1 determines whether or not error information has been generated in the settlement process (S86). If error information has been generated (S86; YES), the error is displayed on the display unit 22a of the touch panel unit 22. Information is displayed (S87). In response to the error display, the cashier person changes the payment amount of each payment method type on the payment screen so that the error is eliminated.

  When the error information is not generated (S86; NO), the POS register device 1 sends the calculated change amount to the automatic change machine of the cash drawer 27 to instruct change output (S88). When the cashier has changed, the cashier output the change output from the automatic change machine to the shopper and ends the settlement of the transaction.

  Hereinafter, the details of the above-described settlement process (S85) will be described with reference to FIG.

  First, the POS register device 1 calculates the total product price of the products registered in the payment target (S90). Specifically, the POS register device 1 calculates the total product price by summing the selling price information of each product stored in the transaction information storage unit 204. The POS register device 1 sets the total merchandise amount as the remaining amount (S91).

  Subsequently, the POS register device 1 acquires, from the payment information holding unit 207, the payment amount of the payment method type in which the earliest settlement order is set among the preset settlement orders (S92). In this embodiment, the order of credit cards, points, cash vouchers, and cash is preset as the order of payment. That is, the first settlement pattern is selected as the initial value for the settlement order of the cash voucher and the cash. The POS register device 1 subtracts the acquired payment amount from the remaining amount, and sets the subtracted result as a new remaining amount (S93).

  Next, the POS register device 1 determines whether or not the remaining amount is greater than 0 (S94).

  When the remaining amount becomes 0 or less (S94; NO), the POS register device 1 further determines whether or not an unprocessed payment method type remains in the payment information holding unit 207 (S110). When an unprocessed payment method type remains in the payment information holding unit 207 (S110; YES), the POS register device 1 further increases the payment method even though the payment amount has already exceeded the total product amount. Since the payment amount by type is registered, error information indicating that the payment amount by the extra payment method type is registered is generated (S111).

  The POS register device 1 calculates a change amount based on the remaining amount when the remaining amount is 0 or less (S94; NO) and there is no unprocessed payment method type (S110; NO) ( S112).

  Subsequently, the POS register device 1 determines whether or not the change amount is greater than 0 and the payment method type that is finally settled is a cash voucher that does not give change (S113). Here, when the change amount is larger than 0 and the payment method type settled last is a cash voucher that does not give change (S113; YES), the POS register device 1 is in spite of the change being generated. Since a voucher that does not change is used, error information indicating that no change is generated is generated (S114).

  If the change amount is 0, or the payment method type that is finally settled is not a cash voucher that does not give change (S113; NO), the POS register device 1 stores product information stored in the transaction information storage unit 204, The payment amount of each payment method type stored in the payment information holding unit 207, the calculated change amount, etc. are stored in the journal storage unit 211 as sales information of the current target transaction (S115), and the payment process is completed.

  On the other hand, even when the remaining amount is larger than 0 (S94; YES), the POS register device 1 determines whether or not an unprocessed payment method type remains in the payment information holding unit 207 (S95). When the remaining amount is larger than 0 (S94; YES) and there is no unprocessed payment method type remaining in the payment information holding unit 207 (S95; NO), the POS register device 1 displays the payment amount (deposit amount). Error information indicating that there is a shortage is generated (S96).

  If the remaining amount is greater than 0 (S94; YES) and an unprocessed payment method type remains in the payment information holding unit 207 (S95; YES), the POS register device 1 determines whether the next in the order of payment is a cash voucher. It is determined whether or not (S97). When the payment order is not a cash voucher (S97; NO), the POS register device 1 acquires the payment amount of the payment method type with the next highest payment order from the payment information holding unit 207 (S100). Thereafter, the POS register device 1 executes the process (S93) and subsequent steps for the payment amount of the acquired payment method type.

  The POS register device 1 determines Condition 1 and Condition 2 when the next in the order of payment is a cash voucher (S97; YES) (S98). Condition 1 is the condition that the amount paid by the next voucher in the order of payment exceeds the remaining amount. Condition 2 is the amount of cash paid in the order of payment after the next voucher in the order of payment. It is a condition whether it does not exceed. In the POS register device 1, when the payment amount by the next cash voucher in the payment order exceeds the remaining amount (S98; YES), or the cash payment amount in the payment order after the next cash voucher in the payment order is the remaining amount. Is not exceeded (S98; YES), the first settlement pattern is switched to the second settlement pattern (S99). As a result, the settlement order is in the order of credit card, points, cash, and cash voucher. That is, the determination in the step (S99) corresponds to the determination as to whether or not the shopper wants to pay a fraction of the total amount of goods with cash. On the other hand, the POS register device 1 does not exceed the remaining amount of money paid by the next cash voucher in the order of payment (S98; NO), and is paid by cash in the order of payment after the next cash voucher in the order of payment. When the amount exceeds the remaining amount (S98; NO), the first settlement pattern is maintained.

  In the example of FIG. 9, the case where there are a plurality of payment method types having the same settlement order is not specified, but such payment method types may be settled in an arbitrary order. For example, payment method types for which the same settlement order is set may be settled in the order in which the payment screen is set, or may be settled in descending order of payment amount.

[Operation and Effect in First Embodiment]
As described above, in the first embodiment, when the payment target registration is completed, the payment screen is displayed. On this payment screen, the payment amount can be set for each of the plurality of payment method types desired by the shopper. . The payment amount for each of the plurality of payment method types set on this payment screen is held by the payment information holding unit 207. Then, payment amounts of all payment method types desired by the shopper are set on the payment screen, and when a predetermined user operation is performed on the payment screen, the settlement process is performed based on the held payment amounts of each payment method type. Executed. In the settlement process, change calculation is performed based on the settlement order determined in advance for each payment method type.

  Therefore, according to the first embodiment, even when a plurality of payment method types are used, they can be set together on the payment screen, and appropriate settlement can be performed regardless of the registration order of payment methods. .

  Furthermore, in the first embodiment, a plurality of error checks are performed at the time of change calculation. Specifically, it is checked whether or not an extra payment method type payment amount is set. Furthermore, the amount of money paid by a cash voucher that issues change is managed separately from the amount of money paid by a cash voucher that does not change, so that a cash voucher that does not change money is used even if change is generated. Therefore, error information indicating that no change is generated is generated. Further, error information indicating that the payment amount is insufficient is generated.

  Thereby, according to the first embodiment, even if the cashier person does not consider the registration order of payment methods at all, it is possible not only to prevent the occurrence of a settlement error associated therewith, but also to change with a voucher that does not give change. It is possible to prevent inconveniences on the shopper side or the store side due to the fact that no money is generated. In addition, the cashier does not use extra effort to achieve this.

  Furthermore, in the first embodiment, in the change calculation, the settlement order of the cash voucher and the cash is switched according to a predetermined condition. Thereby, even when the shopper wants to pay the fraction with cash and pay the remaining amount with another payment method, the change can be appropriately calculated. Again, the cashier does not need to consider the registration order of payment method types.

[Second Embodiment]
Regarding transactions for which settlement has already been completed, sales information may be changed due to returns of all or some products, correction of selling prices, and the like. Hereinafter, a transaction that has already been settled is referred to as a completed transaction, and a transaction that is performed after the sales information of the completed transaction is changed is referred to as a regeneration transaction. In the above case, for example, the paid amount of the returned product or the difference due to the correction of the selling price is refunded to the shopper. However, depending on the amount of the refund, the shopper may want to change the payment method used in the completion transaction. For example, in a renewal transaction, a shopper may wish to stop paying the credit card used in the completion transaction and make all cash payments.

  Therefore, the POS register device 1 in the second embodiment makes it possible to change the payment method from the original completion transaction in the reproduction transaction. Hereinafter, the POS register device 1 in the second embodiment will be described focusing on the contents different from the first embodiment. In the following description, the same contents as those in the first embodiment are omitted as appropriate.

[Processing configuration]
FIG. 10 is a diagram illustrating a processing configuration example of the POS register device 1 according to the second embodiment. The cashier apparatus 20 further includes a sales change unit 301 in addition to the configuration of the first embodiment. Similarly to the other processing units, the sales change unit 301 is realized, for example, by executing a program stored in the memory 3 by the CPU 2.

  The sales changing unit 301 changes the sales information of the completion transaction. Specifically, the sales changing unit 301 can specify a completion transaction such as a receipt number in response to an operation of the keyboard 21 or the touch panel 22b on a partial return screen displayed by the display processing unit 206. And the change information of the merchandise information with respect to the completion transaction is acquired. The sales changing unit 301 extracts sales information regarding the completed transaction to be changed from the journal storage unit 211 based on the information that makes it possible to identify the completed transaction, and changes the extracted sales information.

  The sales changing unit 301 changes the product information in the sales information extracted from the journal storage unit 211 based on the change information. The change in the product information is, for example, a change in selling price information of a certain product or deletion of product information corresponding to the returned product. The sales changing unit 301 changes the payment information in the sales information extracted from the journal storage unit 211 as follows. The sales change unit 301 sums up the amount paid by the change machine cash, the amount paid by the manually entered cash, and the amount paid by the cash voucher. Set the payment amount to 0.

  The sales changing unit 301 stores the product information in the changed sales information in the transaction information storage unit 204, and stores the payment information in the changed sales information in the payment information holding unit 207.

  The calculation unit 205 calculates the total product amount of the reproduction transaction based on the product information changed by the sales changing unit 301 and stored in the transaction information storage unit 204. Further, the calculation unit 205 calculates the total payment amount of the regeneration transaction based on the payment information changed by the sales changing unit 301 and held in the payment information holding unit 207. This total amount of payment corresponds to the total amount already paid in the original completed transaction.

  The display processing unit 206 causes the display unit 22a to display various screens for accepting returns, sales price corrections, and the like. For example, the display processing unit 206 displays a partial return screen as shown in FIG.

  FIG. 11 is a diagram illustrating an example of a partial return screen. In the partial return screen G110 shown in FIG. 11, a list of products included in the completed transaction is displayed on the left side, and a list of products registered as return targets is displayed on the right side. In the example of FIG. 11, two cherries are registered for return. When the return object registration as shown in FIG. 11 is performed on the partial return screen, the sales changing unit 301 deletes the product information of the product registered in the return object among the products included in the completion transaction. By changing the sales information of the completed transaction.

  The display processing unit 206 displays a payment screen regarding the replay transaction on the display unit 22a when a request for changing the refund method regarding the replay transaction is received and a credit card is included in the payment method type regarding the replay transaction. Display. The refund method change request is acquired, for example, by operating the refund method change button G111 on the partial return screen G110 shown in the example of FIG. 11 with the keyboard 21 or the touch panel 22b. The structure of the payment screen is the same as in the first embodiment. However, the change cash field is assigned to the original transaction cash field, and the change amount field is assigned to the refund amount field.

  The display processing unit 206 includes the payment amount for each payment method type related to the reproduction transaction, which is held in the payment information holding unit 207, in the payment screen. Thus, the change amount of money changed by the sales changing unit 301 is displayed in the original transaction cash column of the payment screen. In addition, the display processing unit 206 sets the original transaction cash field to unchangeable. Therefore, the total amount of cash already paid in the original completed transaction (cash machine cash and manually entered cash) and the amount of cash voucher is displayed in a non-configurable state in the original transaction cash column on the payment screen. become. Thereby, it is possible to prevent a voucher that has already been paid in the original completion transaction from being returned. This is because it is generally prohibited to reuse vouchers that have already been paid and settled.

  FIG. 12 is a diagram illustrating an example of a payment screen related to a regeneration transaction. In this case, the total amount (4,550 yen) of the reproduction transaction corresponding to the changed sales information is displayed in the display column G51. In addition, the display column G52 displays the payment amount for each of the plurality of payment method types, and the display column G121 included in the display column G52 displays the total amount of payment already paid in the original completed transaction. The According to the example of FIG. 12, in the original completion transaction, 5,000 yen is paid by credit card, 890 yen is paid by cash voucher or cash, and 5,890 yen is paid in total. In the display column G54, a refund amount (1,340 yen) is displayed.

  In the example of FIG. 12, when a user operation for canceling the payment amount (5,000 yen) by credit card is performed, the display processing unit 206 updates the display of the payment screen as follows. The display processing unit 206 updates the display of the total payment amount from 5,890 yen to 890 yen, and subtracts the total payment amount (890 yen) from the product total amount (4,550 yen) in the display column G51. The displayed amount (3,660 yen) is updated, and the display in the display column G54 is updated to 0 yen.

  The card settlement processing unit 208 generates minus settlement data of the payment amount in response to a user operation for canceling the payment amount by the credit card included in the payment screen. This negative settlement data is transmitted to a credit card settlement system (not shown) via the communication device 4. When the credit card negative settlement is completed, the card payment processing unit 208 reflects the change in the payment information holding unit 207.

  The settlement processing unit 209 detects a predetermined user operation on the payment screen, and based on the total amount of goods calculated by the calculation unit 205 and the payment amount related to each of the plurality of payment method types held in the payment information holding unit 207. The settlement process for the renewal transaction to be changed is executed. In this payment process, the payment processing unit 209 calculates the refund amount, and after the calculation, the changed sales information is reflected in the journal data stored in the journal storage unit 211. The refund amount is calculated in the same manner as the change amount calculation in the first embodiment. In the second embodiment, the refund amount is calculated instead of the change amount.

[Operation example]
Hereinafter, the settlement processing method in the second embodiment will be described with reference to FIG. FIG. 13 is a flowchart showing an operation example of the POS register device 1 in the second embodiment. In FIG. 13, the same steps as those in the operation example in the first embodiment are denoted by the same reference numerals as those in FIG. 8. Only the steps different from those of the second embodiment will be described below. In the second embodiment, each process shown in FIG. 13 is executed by the cashier apparatus 20.

  The POS register device displays information such as a partial return screen (see FIG. 11) on the display unit 22a and detects an operation on these screens, and information that makes it possible to identify a completed transaction to be changed, and its completion Product information change information for the transaction is acquired (S130). The POS register device 1 determines the presence of a request for changing the refund method for the reproduction transaction (S131). This refund method change request is obtained by operating a refund method change button on a partial return screen or the like.

  When the POS register device 1 receives the refund method change request (S131, YES), the POS register device 1 extracts the sales information related to the completion transaction to be changed from the journal storage unit 211 based on the information that enables the acquired completion transaction to be specified. . The POS register device 1 changes the product information in the extracted sales information based on the change information (S132).

  The POS register device 1 also changes the payment information in the sales information extracted from the journal storage unit 211 (S132). Specifically, the POS register device 1 sums up the payment amount by change machine cash, the payment amount by manual input cash, and the payment amount by cash voucher, and uses this total amount as the payment amount by change machine cash. Set the payment amount by and the payment amount by cash voucher to 0.

  The POS register device 1 stores the product information changed in this way in the transaction information storage unit 204, and stores the changed payment information in the payment information holding unit 207 (S133). Subsequently, the POS register device 1 displays a payment screen using information held in the payment information holding unit 207 (S82). Thereafter, the POS register device 1 operates in the same manner as in the first embodiment. However, in the second embodiment, the change is output from the change. In the second embodiment, the POS register device 1 instructs the automatic change machine of the cash drawer 27 to output the refund amount calculated in the settlement process (S134). ).

[Operation and Effect of Second Embodiment]
In the second embodiment, when a return or sale price change occurs in a transaction that has already been settled (completed transaction), the completed transaction to be changed is identified, and sales information related to the completed transaction is extracted from journal data The extracted sales information is changed. Then, the payment amount for each payment method type included in the changed sales information is held, and a payment screen is displayed using the held payment information, as in the first embodiment. In this payment screen, the payment method used in the original completed transaction is changed, and when the deposit / cash button is pressed, the replay transaction is performed based on the payment amount for each changed payment method type. Settlement is performed.

Therefore, according to the second embodiment, the payment method can be changed from the original completion transaction even when the sales information such as returned goods is changed. Furthermore, even in the change of the payment method, the same effect as that at the time of normal settlement in the first embodiment can be obtained. That is, even when a plurality of payment method types are used in changing the payment method, they can be set together on the payment screen, and appropriate settlement can be performed regardless of the registration order of payment methods.

  In the second embodiment, on the payment screen when the payment method is changed, the payment amount by the cash voucher in the original completion transaction is added to the payment amount by cash and displayed as the original transaction cash in an unchangeable state. . Thereby, according to 2nd Embodiment, it can prevent that the cash voucher already paid by the original completion transaction is not returned.

  Further, in the second embodiment, when the payment amount is canceled by the credit card on the payment screen when the payment method is changed, the credit card minus settlement data is sent to the credit card settlement system, and the credit card minus settlement is performed. Is done. Thereby, according to 2nd Embodiment, when the sales information of the completion transaction in which the credit card payment was used is changed, the payment method without refunding the entire amount of the original credit card payment in cash Can be changed.
