Specifically, in the scene of registering a product to which any of a plurality of tax rates is applied (hereinafter referred to as a multiple tax rate product), a screen that can be intuitively (experienced and visually) understood is provided. Even a clerk (newcomer, etc.) who is unfamiliar with the operation can easily select one of the tax rates. The same applies to the mobile terminal 60 and the settlement device 40 of the second embodiment.

3 to 10 are display examples of the POS terminal 20 according to the first embodiment. Hereinafter, using FIGS. 3 to 10, as specific examples of multiple tax rate products, one favorite lunch (tax-excluded price (main unit price) 554 yen, 8% tax-included price 598 yen, 10% tax-included price 609 yen) The display of the display unit 205 for the clerk in the scene of registering three tuna rice balls (price excluding tax 115 yen, price including 8% tax 124 yen, price including 10% tax 126 yen) will be described. The POS terminal 20 (the same applies to other devices such as the mobile terminal 60 and the settlement device 40 of the second embodiment) is, for example, a file (for example, in its own device or other) that stores whether or not it is a plurality of tax rate products. Refer to the product file stored in the device (or contact another device) to determine whether the product is a multi-tax rate product.

FIG. 3 shows the display contents of the registration screen in the scene where canned beer (10% tax-included price 215 yen) is registered as one item and asparagus (8% tax-included price 215 yen) is registered as two items. The area on the left side of the registration screen is an area for displaying a list of registered products (referred to as a product list area; the same applies to other screens such as a subplanning surface). In the product list area, the registration information of the product (one item of canned beer, two items of asparagus) in the transaction is displayed in an operable (touchable) manner. The area on the right side of the registration screen is the area for displaying preset buttons. The subtotal button BT10 at the bottom of the registration screen is a button that accepts an operation to complete the registration of the product. The subtotal button BT10 is a button whose operation is enabled when at least one product is registered. In the scene of FIG. 3, since two products are registered, the operation of the subtotal button BT10 is effective. Therefore, the subtotal button BT10 is displayed in a display mode (indicated by a solid line frame in the figure) indicating that the operation is effective.

FIG. 4 simply indicates that the clerk scans the barcode attached to the favorite lunch box by the scanner unit 204 from the scene of FIG. 3 (hereinafter, the scanner unit 204 scans the barcode attached to the product XX). It shows the display contents in the scene (that is, scanning the product ○○). That is, when the clerk scans the multiple tax rate products (favorite lunch box) (the same applies when the preset button corresponding to the multiple tax rate products is operated), the POS terminal 20 is on the front surface of the registration screen as shown in FIG. Display the small screen SG01 related to the multiple tax rate products (favorite lunch box).

The small screen SG01 is provided with a message display area MG01 and a product information display area HR01. In the message display area MG01, a message is displayed to encourage the clerk to operate any of the buttons (Yes button BT20, No button BT21, which will be described later). In the product information display area HR01, the prices of the plurality of tax rate products (favorite lunch boxes) according to the sales mode are displayed. Specifically, ¥ 609 (consumption tax 10%) for in-store eating and drinking (eat-in) and ¥ 598 (consumption tax 8%) for take-out (take-out) are listed together. Further, a yes button BT20 and a no button BT21 are arranged on the small screen SG01.

The clerk confirms with the customer and operates (selects) the Yes button BT20 when eating and drinking in the store for the multiple tax rate products (favorite lunch box), and operates the No button BT21 when taking out (selection). select.

FIG. 5 shows the display contents of the registration screen when the clerk operates the No button BT21 of the small screen SG01 from the scene of FIG. That is, when the clerk operates the No button BT21 of the small screen SG01, the POS terminal 20 erases the small screen SG01 and reflects the operation content (operation content to take home) of the small screen SG01 (registration information). Generate, memorize, display, etc.). For example, in the product list area of the registration screen of FIG. 5, the take-out price of the product (favorite lunch box) is displayed as the operation content on the small screen SG01. In addition, the star mark in the product list area on the registration screen of FIG. 5 (the same applies to the registration screens of FIGS. 6 and 9 and the small plan surface of FIG. 10) indicates that the product (in this example, a favorite lunch box) is a product with a plurality of tax rates. It indicates that it corresponds to.

FIG. 6 shows the display contents of the registration screen when the clerk operates the yes button BT20 of the small screen SG01 from the scene of FIG. That is, when the clerk operates the yes button BT20 of the small screen SG01, the POS terminal 20 erases the small screen SG01 and reflects the operation content (operation content of eating and drinking in the store) on the small screen SG01 (registration information). Generation, storage, display, etc.). For example, in the product list area of the registration screen of FIG. 5, the price of food and drink in the store for the product (favorite lunch box) is displayed as the operation content on the small screen SG01.

In this example, the number of purchases of the favorite lunch box is a single number, but if the number of purchases is multiple, the clerk may register multiple items according to the number of purchases while the small screen SG01 is being displayed. An operation (for example, an operation of the "x" button of the key operation unit 208 → an operation of inputting a number, or an operation of the "x" button once or more) is performed. When the clerk performs a plurality of registration operations while the small screen SG01 is being displayed, the POS terminal 20 displays the small screen SG02 (described later) instead of the small screen SG01.

Hereinafter, the description will be made assuming that the clerk operates the No button BT21 of the small screen SG01, but the same applies when the clerk operates the Yes button BT20 of the small screen SG01.

In FIG. 7, the clerk scans the tuna rice ball from the scene of FIG. 5, and then a plurality of registration operations according to the number of purchases “3” (for example, operation of the “x” button of the key operation unit 208 → input of the number of units “ It shows the display contents in the scene where the operation of "3" or the like or the operation of the "x" button twice) is performed. That is, when the clerk scans the multi-tax rate product (tuna rice ball), the POS terminal 20 displays a small screen SG01 (not shown) related to the multi-tax rate product (tuna rice ball) on the front of the registration screen, followed by. When the clerk performs a plurality of registration operations according to the number of purchases "3" while the small screen SG01 is displayed, the POS terminal 20 replaces the small screen SG01 related to the multiple tax rate product (tuna rice ball). A small screen SG02 (Fig. 7) relating to a multi-tax rate product (tuna rice ball) is displayed in front of the registration screen.

In this example, for a product having a plurality of purchases, the clerk performs a plurality of registration operations after scanning the product, but the clerk may perform a plurality of registration operations before scanning the product. .. When a plurality of registration operations are performed before scanning the product, the POS terminal 20 does not have to display the small screen SG01. For example, when a clerk performs a plurality of registration operations according to the number of purchases "3" from the scene shown in FIG. 5 and subsequently scans a tuna rice ball, a small screen related to the multiple tax rate product (tuna rice ball) is suddenly displayed. The small screen SG02 (FIG. 7) relating to the plurality of tax rate products (tuna rice balls) may be displayed without displaying SG01 (not shown).

The small screen SG02 is provided with a message display area MG02 and a product information display area HR01. Further, on the small screen SG02, selection buttons BT30 (selection buttons BT30-1, BT30-2, BT30-3) corresponding to the number of registered tuna rice balls (“3” in this example) are arranged. For each selection button BT30, the prices of the multiple tax rate products (Tuna Onigiri) are ¥ 126 (consumption tax 10%) for in-store food and drink (eat-in) and ¥ 124 (consumption tax) for take-out (take-out). 8%) is also written. Further, on the small screen SG02, a yes button BT40 and a button BT41 to take all home are arranged.

The clerk confirms with the customer, and if all three of the multiple tax rate products (tuna rice balls) are to be eaten in the store, the three selection buttons BT30 (selection buttons BT30-1, BT30-2, BT30-3). After operating all of the above, operate the Yes button BT40, and if you want to eat and drink in the store, operate any two of the three selection buttons BT30, and then operate the Yes button BT40. If you want to eat and drink in the store, operate any one of the three selection buttons BT30, then operate the yes button BT40, and if you want to take all three of them home, use the three selection buttons BT30. Operate the button BT41 to take all the items home without operating any of them.

The Yes button BT40 is a button whose operation is enabled when at least one selection button BT30 is selected (selected state). In the scene of FIG. 7, since no selection button BT30 is operated (non-selection state), the operation of the yes button BT40 is not effective. Therefore, the Yes button BT40 is displayed in a display mode (indicated by a broken line frame in the figure) indicating that the operation is not valid. Further, the button BT41 to bring back all is a button whose operation becomes effective when all the selection buttons BT30 are in the non-selected state. In the scene of FIG. 7, since all the selection buttons BT30 are in the non-selected state, the operation of the buttons BT41 to bring back all is effective. Therefore, all the buttons BT41 to be taken back are displayed in a display mode (solid line frame) indicating that the operation is effective.

FIG. 8 shows a small screen when the clerk operates any two of the three selection buttons BT30 of the small screen SG02 (in this example, the selection buttons BT30-1 and BT30-2) from the scene of FIG. The display contents of SG02 are shown.

As shown in FIG. 8, the two selection buttons BT30 (selection buttons BT30-1 and BT30-2) operated by the clerk are displayed in a display mode (indicated by a dot background in the figure) indicating that they are in the selected state. One selection button BT30 (selection button BT30-3) that has not been operated by the clerk is displayed in a display mode (indicated by a plain background in the figure) indicating that it is in a non-selected state. Further, the two selection buttons BT30 (selection buttons BT30-1 and BT30-2) operated by the clerk, that is, the selection button BT30 displayed in the display mode indicating that the selection state is in the selected state, have the plurality of tax rate products. The prices of food and drink in the store of (Tuna rice balls) are displayed. On the other hand, one selection button BT30 (selection button BT30-3) that is not operated by the clerk, and the selection button BT30 displayed in the display mode indicating that it is in the non-selection state, are the multiple tax rate products (tuna rice balls). The take-out price is displayed.

That is, when the POS terminal 20 accepts the operation of one selection button BT30 (for example, selection button BT30-1), the one selection button BT30 (selection button BT30-1) is not selected. Switch from the display mode (plain background) to the effect that it is in the selected state (dot background), display the price of food and drink in the store in the button (delete the take-out price), and select the other two buttons. The BT30 (selection button BT30-2, BT30-3) is displayed in the display mode indicating that it is in the non-selected state, and the take-out price is displayed in the button (the price of food and drink in the store is deleted). Further, the POS terminal 20 switches from the display mode (broken line frame) indicating that the operation is not valid to the display mode (solid line frame) indicating that the operation is valid for the Yes button BT40, and the operation is valid for the button BT41 to be taken back. The display mode indicating that the operation is not valid is switched to the display mode indicating that the operation is not valid. Subsequently, when the POS terminal 20 further accepts the operation of one selection button BT30 (for example, the selection button BT30-2), the one selection button BT30 (selection button BT30-2) is in a non-selected state. The display mode indicating that the item is in the selected state is switched to the display mode indicating that the item is in the selected state, and the price of the food and drink in the store is displayed as the price in the button instead of the take-out price.

The selection button BT30 switches from the non-selected state to the selected state to the non-selected state to ... Each time the operation is performed.

FIG. 16A shows the display contents (small screen SG05 displayed on the front surface of the product confirmation screen) in the scene where the settlement device 40 reads the two-dimensional code 612 for settlement.

After reading the two-dimensional code 612 for settlement, the settlement device 40 simply displays a product confirmation screen when a plurality of tax rate products are not included, and front of the product confirmation screen when a plurality of tax rate products are included. A small screen SG05 is displayed on the screen. In this example, since a plurality of tax rate products (tuna rice balls, salmon lunch boxes) are included, the settlement device 40 displays a small screen SG05 in front of the product confirmation screen as shown in FIG. 16 (A). The product confirmation screen (the same applies to the payment type selection screen described later) is one of the settlement screens.

The small screen SG05 is provided with a plurality of tax rate product display areas HR03. In the multiple tax rate product display area HR03, multiple tax rate products (tuna rice balls, salmon lunch boxes) in the transaction are displayed in a list that can be operated (touchable). Further, on the small screen SG05, a button BT50 for eating and drinking in the store and a button BT51 for changing food and drink in the store are arranged. The in-store food and drink button BT50 can be operated when there is no product changed to in-store food and drink. The change button BT51 for in-store eating and drinking can be operated when there is one or more products changed to in-store eating and drinking.

(When taking out all multiple tax rate products)
If all multi-tax rate products (in this example, tuna rice balls, salmon lunch boxes) are to be taken home, that is, if there are no multi-tax rate products for in-store eating and drinking, the customer operates the small screen SG05 in-store no eating and drinking button BT50. .. When the customer operates the in-store food / drink button BT50, the checkout device 40 erases the small screen SG05.

(When eating and drinking in the store for products with multiple tax rates of quantity 1)

Specify (touch the display area of the multiple tax rate products). When the customer designates a plurality of tax rate products having a quantity of 1 from the multiple tax rate product display area HR03 of the small screen SG05, the settlement device 40 shifts the operation content (designation) to the small screen SG05 (multiple tax rate product display area HR03). To reflect. Specifically, the settlement device 40 changes the display of the plurality of tax rate products (1 piece) on the small screen SG05 (multiple tax rate product display area HR03) from take-out to in-store eating and drinking. For example, in FIG. 16A, when the customer designates a salmon lunch from the multi-tax rate product display area HR03 of the small screen SG05, the settlement device 40 displays the salmon lunch in the multi-tax rate product display area HR03 of the small screen SG05. Is changed from "Salmon bento 1 (take-out) ¥ 432" to "Salmon bento 1 (in-store food and drink) ¥ 440".

If the customer redesignates the salmon lunch in the multiple tax rate product display area HR03, the settlement device 40 displays the salmon lunch in the multiple tax rate product display area HR03 as "salmon lunch 1 (in-store food and drink) ¥ 440". Change from "Salmon bento 1 (take-out) ¥ 432". That is, every time a plurality of tax rate products having a quantity of 1 are designated in the multiple tax rate product display area HR03 of the small screen SG05, the settlement device 40 sells the multiple tax rate products in the multiple tax rate product display area HR03 of the small screen SG05. Switch (take-out, in-store food and drink).

(When eating and drinking in the store for all or part of multiple tax rate products with a quantity of 2 or more)
If the customer wants to eat and drink in the store for all or part of the multiple tax rate products (in this example, tuna rice balls) with a quantity of 2 or more, the multiple tax rate products (in the store) from the multiple tax rate product display area HR03 on the small screen SG05. Specify multiple tax rate products with 2 or more food and drink quantities). When the customer specifies a plurality of tax rate products having a quantity of 2 or more from the multiple tax rate product display area HR03 of the small screen SG05, the settlement device 40 takes out the multiple tax rate products (multiple each) or eats and drinks in the store. A small screen SG06 (a screen corresponding to the small screen SG02 in FIG. 7, not shown) that can be selected is displayed on the front surface of the small screen SG05. The customer operates through the small screen SG06 to decide whether to eat or drink in the store for the plurality of tax rate products (each of the plurality of products). When the customer's operation on the small screen SG06 is completed, the settlement device 40 erases the small screen SG06 and reflects the operation content on the small screen SG06 on the small screen SG05 (multiple tax rate product display area HR03). For example, in FIG. 16A, the customer specifies the area of "Tuna rice ball 3 (in-store food and drink 0, take-out 3) ¥ 372" in the multiple tax rate product display area HR03, and the customer's on the small screen SG06 displayed after the designation. When the operation (operation to make two tuna rice balls into in-store food and drink) is completed, the settlement device 40 displays the tuna onigiri in the multiple tax rate product display area HR03 of the small screen SG05 as "tuna onigiri 3 (in-store food and drink 0). , Take-out 3) ¥ 372 ”will be changed to“ Tuna rice ball 3 (in-store food and drink 2, take-out 1) ¥ 376 ”.

When the customer redesignates the tuna rice ball in the plurality of tax rate product display area HR03, the settlement device 40 displays the small screen SG06 again on the front surface of the small screen SG05. That is, every time a plurality of tax rate products having a quantity of 2 or more are designated in the multiple tax rate product display area HR03 of the small screen SG05, the settlement device 40 displays the small screen SG06 in front of the small screen SG05.

In FIG. 16 (B), from the scene of FIG. 16 (A), the customer changed 2 of all 3 tuna rice balls to in-store eating and drinking (without changing salmon lunch to in-store eating and drinking), and then in the store. The product confirmation screen of the scene where the change button BT51 for eating and drinking is operated is shown.

The product confirmation screen is provided with a product display area HR02. In the product display area HR02, all the products (notebook, tuna rice ball, shampoo, salmon lunch) in the transaction are operably displayed in a list. Further, the product display area HR02 reflects the operation contents of the customer on the small screen SG05. In this example, since the customer changed 2 of all 3 tuna rice balls to in-store food and drink on the small screen SG05, as shown in FIG. 16B, the product display area HR02 has all 3 tuna rice balls. Two are displayed as in-store food and drink, and one is displayed as take-out. Further, on the product confirmation screen, a checkout button BT1402 and a clerk call button BT1403 are arranged. The checkout button BT1402 is a button to be operated when proceeding to checkout. The clerk call button BT1403 is a button to be operated when calling a clerk.

Although not shown, if the customer changes two of the three tuna rice balls to in-store food and drink and the salmon lunch box to in-store food and drink on the small screen SG05, the product shown in FIG. 16 (B). The display of the salmon lunch in the display area HR02 is "Salmon lunch in-store food and drink x 1 ¥ 440" (the display of the tuna rice ball in the product display area HR02 in FIG. 16B is maintained). In addition, if the customer does not eat or drink in the store on the small screen SG05 (when the button BT40 is operated), the display of the tuna rice ball in the product display area HR02 in FIG. 16 (B) is "Tuna rice ball take-out x 3 ¥ 372". (The display of the salmon lunch box in the product display area HR02 of FIG. 16 (B) is maintained).

The customer confirms the contents of the product display area HR02, and if there is no problem, operates the checkout button BT1402. When the customer operates the checkout button BT1402, the checkout device 40 displays a payment type selection screen (not shown) instead of the product confirmation screen. The payment type selection screen is a screen for selecting a payment type (cash, credit card, electronic money, etc.), and buttons corresponding to each payment type and a clerk call button are arranged. The customer operates a button corresponding to a desired payment type on the payment type selection screen to settle the payment.

The customer can also take out the multiple tax rate products / change the food and drink in the store on the product confirmation screen (product display area HR02). For example, in the settlement device 40, when the tuna rice ball is designated in the product display area HR02 of FIG. 16 (B), the tuna rice ball is designated in the multiple tax rate product display area HR03 of the small screen SG05 shown in FIG. 16 (A). As in the case of, the small screen SG06 is displayed, and the operation content on the small screen SG06 is reflected on the product confirmation screen (product display area HR02). Further, for example, in the settlement device 40, when the salmon lunch is designated in the product display area HR02 of FIG. 16 (B), the salmon lunch is designated in the multiple tax rate product display area HR03 of the small screen SG05 shown in FIG. 16 (A). The operation content (designation) is reflected on the product confirmation screen (product display area HR02) as in the case of the above.

The mobile terminal 60 may accept a change operation to in-store food and drink for the plurality of tax rate products scanned when the plurality of tax rate products are scanned (the quantity is 1 because it is the time of scanning). For example, the mobile terminal 60 corresponds to a small screen SG07 (corresponding to the small screen SG01 in FIG. 4) in which when a plurality of tax rate products are scanned, it is possible to select whether to take out the multiple tax rate products (1 piece) or to eat and drink in the store. Screen to be displayed (not shown) is displayed in front of the registration screen. The customer operates whether to eat or drink in the store for the plurality of tax rate products (1 piece) via the small screen SG07. When the customer's operation on the small screen SG07 is completed, the mobile terminal 60 erases the small screen SG07 and reflects the operation content on the small screen SG07 on the registration screen (product list area). For example, when tuna rice balls (8% tax-included price of 124 yen) are scanned as two items from the scene shown in FIG. 14 (A), the mobile terminal 60 displays a small screen SG07 related to the tuna rice balls in front of the registration screen. Then, for example, when the customer performs an operation to eat and drink in the store on the small screen SG07, the mobile terminal 60 displays a registration screen as shown in FIG. 17 (A). In the product list area of the registration screen of FIG. 17A, tuna rice balls (1 piece) are registered as in-store food and drink.

(Changes after registration (except when the quantity is changed) (when the quantity is 1))
After the registration of the plurality of tax rate products (except when the quantity is changed), the mobile terminal 60 may accept the operation of changing the tax rate (sales mode) for the plurality of tax rate products (1 piece). For example, when the customer specifies a plurality of tax rate products (1 piece) in the product list area (touches an area other than the quantity button BT603 in the area of the multiple tax rate products in the product list area), the mobile terminal 60 is the said. Similar to when scanning multiple tax rate products, a small screen SG07 that allows you to select whether to take home or eat or drink in the store for the multiple tax rate products is displayed in front of the registration screen, and the operation details on the small screen SG07. Is reflected on the registration screen (product list area). For example, when the tuna rice ball is designated from the scene of FIG. 17A, the mobile terminal 60 displays the small screen SG07 related to the tuna rice ball in front of the registration screen, and the customer takes it home on the small screen SG07, for example. When the operation to that effect is performed, the mobile terminal 60 displays a registration screen as shown in FIG. 14 (B). In the product list area of the registration screen of FIG. 14B, tuna rice balls (1 piece) are registered as take-out.

(Changes after registration (except when the quantity is changed) (when the quantity is 2 or more))
After the registration of the plurality of tax rate products (except when the quantity is changed), the mobile terminal 60 may accept the operation of changing the tax rate (sales mode) for the plurality of tax rate products (two or more). For example, when the customer specifies a plurality of tax rate products (two or more) in the product list area (touches an area other than the quantity button BT603 in the area of the multiple tax rate products in the product list area), the mobile terminal 60 A small screen SG06 (a screen corresponding to the small screen SG02 in FIG. 7) that allows you to select whether to take home or eat and drink in the store for the multiple tax rate products (each of them) is displayed in front of the registration screen, and the small screen is displayed. The operation details in SG06 are reflected in the registration screen (product list area). For example, when the tuna rice ball is designated from the scene of FIG. 15A, the mobile terminal 60 displays the small screen SG06 related to the tuna rice ball in front of the registration screen, and for example, the customer displays all three on the small screen SG06. When the operation to eat and drink in the store is performed for two of them, the mobile terminal 60 displays a registration screen as shown in FIG. 17 (B). In the product list area of the registration screen of FIG. 17B, two out of three tuna rice balls are registered as take-out.

(Change after registration (when quantity is changed))
The mobile terminal 60 may accept the operation of changing the tax rate (sales mode) of the plurality of tax rate products when the quantity is changed after the registration of the plurality of tax rate products. For example, when a customer operates the enter button BT609 after performing a quantity increase operation or a quantity decrease operation on a small screen SG04 (see FIG. 14) for changing the quantity of a certain multiple tax rate products (specifically, the quantity is increased or decreased). (If there is), the mobile terminal 60 displays the small screen SG06 related to the plurality of tax rate products (multiple each) or the small screen SG07 related to the multiple tax rate products (1 piece), and the small screen SG06 (or). The operation content on the small screen SG07) is reflected on the registration screen (product list area). That is, when the quantity (changed quantity) at the time of operating the enter button BT609 is 2 or more, the mobile terminal 60 selects whether to take out the multiple tax rate products (multiple each) or to eat and drink in the store. The possible small screen SG06 is displayed in front of the registration screen, and the operation content on the small screen SG06 is reflected on the registration screen (product list area). On the other hand, when the quantity (changed quantity) at the time of operating the enter button BT609 is 1 (when the quantity is reduced from 2 or more to 1), the mobile terminal 60 takes out the plurality of tax rate products (1 piece). A small screen SG07 that allows selection of whether to eat or drink in the store is displayed in front of the registration screen, and the operation content on the small screen SG07 is reflected in the registration screen (product list area).

Although the embodiment of the present invention (first embodiment, second embodiment) has been described above, the configuration of the device, the configuration of data, the flow of processing, the mode of display and output, and the like are as shown in the following modifications. , Can be changed as appropriate. In addition, the following modifications may be combined as appropriate.

(1) In the first embodiment, the example in which the POS terminal 20 displays the small screen SG02 as a screen for determining or changing the tax rates of each of the two or more multiple tax rate products has been described, but the two or more multiple tax rates have been described. The screen to be displayed is not limited to the small screen SG02 as long as the tax rate of each product can be determined or changed. The same applies to the small screen SG06 in the second embodiment.

FIG. 18 is a display example of the POS terminal 20 according to the first embodiment. For example, the POS terminal 20 may display the small screen SG12 shown in FIG. 18 instead of the small screen SG02 shown in FIG. As shown in FIGS. 7 and 18, the small screen SG12 (FIG. 18) is provided with a decision button BT42 in place of the yes button BT40 and the button BT41 to bring back all of the small screen SG02 (FIG. 7).

The clerk confirms with the customer, and after operating all three selection buttons BT30 when all three are eaten in the store for multiple tax rate products (tuna rice balls in FIG. 18 as in the example of FIG. 7). , When the decision button BT42 is operated and two are used for in-store eating and drinking, after operating any two of the three selection buttons BT30, the decision button BT42 is operated and one is used for in-store eating and drinking. In that case, after operating any one of the three selection buttons BT30, operate the enter button BT42, and if all three are to be taken home, do not operate any of the three selection buttons BT30. Then, the enter button BT42 is operated.

(2) Further, in the first embodiment, an example of displaying (adding) the registration information of the product in the product list area each time the product is scanned (or the preset button is operated) has been described, but the same product has been described. When is scanned (or operated the preset button) multiple times, the registration information of multiple lines according to the number of scans (or the operation of the preset button) may be displayed in the product list area, or multiple scans may be performed. (Or the operation of the preset button) may be displayed in one line of the registered information. For example, when the scan of product A (200 yen) (1 piece registration) → the scan of product B (150 yen) (1 piece registration) → the scan of product A (2 pieces registration), the POS terminal 20 is the product A. And the product B may be displayed in the product list area as in display mode 1 (below) or as in display mode 2 (below).
(Display mode 1 of the product list area)
Product A within ¥ 200 Product B within ¥ 150 2 pieces Product A within ¥ 400 (Display mode 2 of the product list area)
3 pieces Product A within ¥ 600 Product B within ¥ 150

The difference is that the quantity button BT603 is displayed, but the same applies to the mobile terminal 60 of the second embodiment. That is, the mobile terminal 60 may display the product A and the product B in the product list area as in the display mode 1'(below) or as in the display mode 2'(below). When the mobile terminal 60 displays the display mode 2', the settlement device 40 also displays the display mode 2', but when the mobile terminal 60 displays the display mode 1', the payment is made. The device 40 may be displayed as in display mode 1'or as in display mode 2'.
(Display mode 1'of the product list area)
Product A x 1 ¥ 200
Product B x 1 ¥ 150
Product A x 2 ¥ 400
(Display mode 2'of product list area)
Product A x 3 ¥ 600
Product B x 1 ¥ 150

(3) In the case of a mode in which one line of registration information obtained by aggregating multiple scans (or preset button operations) is displayed in the product list area in relation to the above (2) (display mode 2, display mode). (In the case of 2'), when changing the tax rate (sales mode) for multiple tax rate products that are aggregated for multiple times and displayed in one line, when changing the tax rate (sales mode) for multiple tax rate products with 2 or more registrations. A small screen (small screen SG02, small screen SG06, small screen SG12, etc.) is displayed.

(4) In the above embodiment, an example in which the tax rate (sales mode) can be determined and changed for each of the plurality of tax rate products having 2 or more registrations has been described, but it is not necessary to determine and change each of them. In other words, in the above embodiment, for a plurality of tax rate products with 2 or more registrations, a part can be freely selected as 10% (food and drink in the store) and the rest (other part) can be freely selected as 8% (takeout). However, instead of this, only two choices, 8% (take-out) or 10% (in-store eating and drinking), may be allowed. For example, in the device operated by the customer (mobile terminal 60, checkout device 40), only two choices, 8% (take-out) or 10% (in-store eating and drinking), are allowed at once. May be good. In addition, on the store side (service A), the tax rate (sales mode) is determined for each of the multiple tax rate products with 2 or more registrations, and whether or not it can be changed is set (set for all customers or individually for each customer). (Set to) may be possible.

(5) In the above embodiment, every time a plurality of tax rate products are scanned (or a preset button is operated), a small screen (small screen SG01 or the like) is displayed to display the tax rate (sales mode) of the multiple tax rate products. Although the example of confirmation was given, it is not necessary to confirm the tax rate (sales mode) of the multiple tax rate products every time the multiple tax rate products are scanned (or the preset button is operated). For example, at the start of a transaction (before registration of one item), it is confirmed whether or not there is food or drink in the store, and if there is no food or drink in the store, any of the multiple tax rate products is scanned (or the preset button is operated). Even if there is, you may always register as 8% (take-out) without displaying the small screen (small screen SG01 etc.).

Specifically, in the first embodiment, the store clerk confirms with the customer whether or not there is food or drink in the store at the start of the transaction, and if the customer receives a reply that there is no food or drink in the store, the POS terminal 20 declares that there is no food or drink in the store. An operation (for example, an operation of the "no eating and drinking in the store" button of the key operation unit 208) may be performed. The POS terminal 20 always registers 8% (take-out) without displaying a small screen when a plurality of tax rate products are scanned (or a preset button is operated) in a transaction in which there is a declaration of no food or drink in the store. If there is an offer to change to in-store food and drink for a specific multiple tax rate product after declaring no in-store food and drink, specify the multiple tax rate product from the product list area and take out (8%) to eat and drink in the store (8%). Change to 10%).

Further, in the second embodiment (in the case where the mobile terminal 60 described with reference to FIG. 17 accepts an operation of changing to in-store eating and drinking), for example, at the start of a transaction, the customer himself declares that there is no in-store eating and drinking on the mobile terminal 60. (For example, the operation of the "no food and drink in the store" button arranged on the screen displayed before the start of the transaction) may be performed. Hereinafter, the operation of the mobile terminal 60 in the transaction in which the in-store food and drink is declared is the same as the operation of the POS terminal 20 described above.

(6) In the first embodiment, the POS terminal 20 has been described as an installation type device capable of registering a plurality of tax rate products, but other devices may be used. For example, multiple tax rates for a full-self registration settlement device installed in the settlement area of a store where the customer himself registers and settles the product, or a semi-self settlement device where the customer himself setstles the product registered by the clerk in another device. A screen (small screen SG01, small screen SG02, small screen SG05, etc.) for determining or changing the tax rate of the product may be displayed.

(7) In the second embodiment, the mobile terminal 60 has been described as a mobile (portable) device capable of registering a plurality of tax rate products, but other devices may be used. For example, on a smartphone (or tablet terminal) that the store lends to customers visiting the store, or on a shopping cart (or a display that can be attached to and detached from the shopping cart) that has a display unit, a screen (small) that determines or changes the tax rate of multiple tax rate products. Screen SG01, small screen SG02, small screen SG05, etc.) may be displayed.

(8) In the above embodiment, an example of displaying a small screen (small screen SG01, SG02, SG05, etc.) as a screen related to the sales mode (consumption tax rate) of a plurality of tax rate products has been described, but even if it is displayed as a full screen. good. For example, in the first embodiment, the POS terminal 20 displays a small screen SG01 in front of the registration screen of FIG. 3 when the clerk scans the favorite lunch box while displaying the registration screen of FIG. 3, for example. (FIG. 4), instead of the registration screen of FIG. 3, the POS terminal 20 displays the same contents as the small screen SG01 (not the small screen). A screen to be displayed in the entire area; referred to as screen a) may be displayed. When the button on the screen a corresponding to the yes button BT20 on the small screen SG01 (or the button on the screen a corresponding to the no button BT21 on the small screen SG01) is operated, the POS terminal 20 is operated. , A registration screen (a registration screen that reflects the operation content on the screen a) is displayed instead of the screen a. Further, in the second embodiment, the settlement device 40 has described, for example, a scene in which the two-dimensional code 612 for settlement is read, and an example in which the small screen SG05 is displayed in front of the product confirmation screen (FIG. 16A). Instead of this, in the above case, the settlement device 40 may simply display a screen displaying the same contents as the small screen SG05 (a screen displayed in the entire area, not a small screen; referred to as screen b). .. When the button on the screen b corresponding to the in-store food / drink button BT50 on the small screen SG05 (or the button on the screen b corresponding to the change button BT51 for in-store food / drink on the small screen SG05) is operated. , The settlement device 40 displays a product confirmation screen (a product confirmation screen that reflects the operation content on the screen b) instead of the screen b. In addition, in a part of the other screens (registration screen, small plan surface, product confirmation screen, etc.) (enlarge the display area as necessary), the same as the small screen (small screen SG01, SG02, SG05, etc.). The contents of may be displayed.

(9) In the above embodiment, the case of operating the button on the screen and the case of operating the button on the key operation unit 208 have been described as the operation, but the operation may be either button. That is, with respect to the operation described as operating the button on the screen, the button of the key operation unit 208 is operated by arranging a similar button on the key operation unit 208 in place of or in addition to the button on the screen. Alternatively, the operation described as operating the button of the key operation unit 208 may be performed on the screen by arranging a similar button on the screen in place of or in addition to the operation of the button of the key operation unit 208. It may be the one that operates a button.

(10) In the above embodiment, an example of displaying the tax rate and the tax-included price with the product as the tax-included notation has been described (Fig. 4 etc.), but in addition to the above, the tax-excluded price (main unit price) and the tax amount are displayed. May be good. Further, in the above embodiment, the product is described as tax-included, but it may be expressed as tax-excluded. In the case of tax-excluded notation, the tax-excluded price, tax rate, tax amount, and tax-included price may be displayed.

(11) In the above embodiment, two types of tax rates of 8% and 10% are exemplified as the tax rates of the plurality of tax rate products, but other tax rates may be used, or three or more types of tax rates may be used.

(12) All or part of each function (input / output, storage, processing (including judgment)) in the POS terminal 20 of the first embodiment is realized by another device different from the device described as the execution subject of the function. You may. For example, as the processing of the POS terminal 20, at least a part of the processing described with reference to the flowcharts of FIGS. 11 to 13 is replaced with the POS terminal 20 by a store controller (not shown) or a cloud server (not shown). May be executed. In relation to the above, the POS terminal 20 may function as a so-called thin client specialized in an input / output interface or the like. For example, the POS terminal 20 receives various inputs (customer operation, detection by a device such as a scanner), transmits input information (operation information, image information, etc.) to a cloud server, and subsequently, the cloud server POS. Processing is executed according to the information received from the terminal 20 (input information in the POS terminal 20), the processing result (update screen information, etc.) is transmitted to the POS terminal 20, and then the POS terminal 20 receives from the cloud server. The operation (display on the display unit, etc.) may be performed according to the information (processing result by the cloud server). That is, the cloud server may execute a program for controlling the operation of the POS terminal 20. The same applies to the mobile terminal 60 and the settlement device 40 of the second embodiment.
