[0008] Fig. 1 is a diagram showing an example of the configuration of a sales system 1 according to this embodiment. The sales system 1 includes a registration device 10, a settlement device 20, a transaction status management device 70, and a store controller 80. The sales system 1 can be introduced in various business formats (supermarkets, convenience stores, drug stores, home centers, home appliance retailers, etc.). Each device is installed in the store (product display area, accounting area, back yard, etc.).

[0009] In addition, the number of each device is an example in Fig. 1. For example, in Fig. 1, "..." is illustrated to the right of the registration device 10, etc., but the number of registration devices 10, etc. installed in the store may be one or more.

[0010] The registration device 10 is a device that registers products based on the operation of a store clerk. The registration device 10 and the settlement device 20 constitute a semi-self-service system. Although not shown in the figure, the registration device 10 includes, for example, a CPU 101, a memory unit 102, a store clerk display unit 103, a scanner unit 104, an operation unit (one or more hard keys) 105, a customer display unit 106, a communication unit 110, a printing unit 111, and an audio output unit 112.

[0011] The settlement device 20 is a device that acquires registration information by the registration device 10 and settles the payment based on the customer's operation. Although not shown in the figure, the settlement device 20 includes, for example, a CPU 201, a memory unit 202, a display unit 206, a non-cash payment unit (payment terminal) 208, a cash payment unit (change machine) 209, a communication unit 210, a printing unit 211, an audio output unit 212, an imaging unit (camera) 213, a light emitting unit 214, a monitoring display unit 215, and a detection unit (human sensor) 220. The settlement device 20 may have a support pole, and the light emitting unit 214, the monitoring display unit 215, and the detection unit 220 may be provided on the support pole.

[0012] The transaction status management device 70 is a device that manages devices installed in a store (monitoring and controlling processing status, operating status, etc.). The transaction status management device 70 may also manage operators of devices installed in a store (monitoring customers who are using the devices, monitoring the operation contents of customers who are using the devices, and checking the operation contents of customers after use). The transaction status management device 70 comprises at least a CPU, a memory unit, a display unit (which may be configured as a touch panel), an operation unit (keyboard, mouse, etc.), and a communication unit. The transaction status management device 70 is used by store clerks.

[0013] The store controller 80 is a server that mainly handles communication of information between devices installed inside the store and devices installed outside the store. The store controller 80 includes at least a CPU, a memory unit, and a communication unit.

[0014] (Other devices) In addition, devices other than the above-mentioned devices may be installed in the sales system 1 (in the store). For example, a so-called self-service (semi-self-service) registration and settlement device 30 (not shown) may be installed, which registers products based on the operation of a store clerk and settles the payment based on the operation of a customer. The registration and settlement device 30 has a display unit and a scanner unit on the store clerk side (one side of the housing) and a display unit and a payment unit on the customer side (the other side of the housing). Although not shown, the registration and settlement device 30 includes, for example, a CPU 301, a memory unit 302, a store clerk side display unit 303, a scanner unit 304, an operation unit 305, a customer side display unit 306, a non-cash payment unit 308, a cash payment unit 309, a communication unit 310, a printing unit 311, an audio output unit 312, and an imaging unit 313.

[0015] Also, for example, a so-called self-service (full-self) registration and settlement device 40 (not shown) may be installed, which registers products based on the customer's operation and settles the payment based on the customer's operation. Although not shown, the registration and settlement device 40 includes, for example, a CPU 401, a storage unit 402, a display unit 406, a scanner unit 407, a non-cash payment unit 408, a cash payment unit 409, a communication unit 410, a printing unit 411, an audio output unit 412, an imaging unit 413, a light emitting unit 414, a monitoring display unit 415, and a detection unit 420. The registration and settlement device 40 may have a support pole, and the light emitting unit 414, the monitoring display unit 415, and the detection unit 420 may be provided on the support pole.

[0016] Also, for example, a registration settlement device 50 (not shown) having a plurality of operation modes, for example, a normal mode (an operation mode in which products are registered based on the operation of a store clerk and settlement is made based on the operation of a customer) and a full self-service mode (an operation mode in which products are registered based on the operation of a customer and settlement is made based on the operation of the customer), may be installed. The registration settlement device 50 has a display unit and a scanner unit on the store clerk side, and a display unit, a scanner unit and a settlement unit on the customer side. Although not shown, the registration settlement device 50 has, for example, a CPU 501, a memory unit 502, a store clerk side display unit 503, a store clerk side scanner unit 504, an operation unit 505, a customer side display unit 506, a customer side scanner unit 507, a non-cash settlement unit 508, a cash settlement unit 509, a communication unit 510, a printing unit 511, an audio output unit 512, an imaging unit 513, a light emitting unit 514, a monitoring display unit 515, and a detection unit 520. Registration and settlement device 50 may have a support pole, on which light emitting unit 514, monitoring display unit 515, and detection unit 520 may be provided. In the normal mode, clerk-side scanner unit 504 is mainly used for product registration by the clerk. In the full self-service mode, customer-side scanner unit 507 is mainly used for product registration by the customer.

[0017] (Subtotal price reduction) In this store, some products are not eligible for subtotal reductions (subtotal discounts / subtotal discounts). In other words, the store implements subtotal reductions that apply to all or part of the subtotal amount (total amount). In other words, if the customer's registered products do not include products that are not eligible for subtotal reductions, the store will implement a subtotal reduction that applies to the subtotal amount (the entire subtotal amount), and if the customer's registered products include products that are not eligible for subtotal reductions, the store will implement a subtotal reduction that applies to part of the subtotal amount (the subtotal amount excluding the amounts of products that are not eligible for subtotal reductions).

[0018] Products that are not subject to subtotal discounts are set (stored) in the sales system 1. Products that are not subject to subtotal discounts may be stored in the memory unit 102 of the registration device 10, or may be stored in another device that the registration device 10 can refer to (or inquire about) via communication (e.g., the store controller 80, a server outside the store (not shown), etc.). Products that are not subject to subtotal discounts can be set, for example, for each store and each day.

[0019] In the following explanation, the items that are not subject to the subtotal discount are cigarettes (all brands, always) and XX brand rice, which is one of today's special sale items.

[0020] 2 to 12 are display examples of the registration device 10 (display examples on the store clerk display unit 103). Fig. 2 is an example of a registration screen displayed by the registration device 10. For example, when the registration device 10 registers, based on the operation of the store clerk, XX bread (tax-excluded price 200 yen) as the first product, XX lunch box (tax-excluded price 500 yen) as the second product, XX cigarettes (tax-inclusive price 580 yen) as the third product, XX tomatoes (tax-excluded price 200 yen (price for 2 pieces)) as the fourth product, and XX tea (tax-excluded price 150 yen) as the fifth product, the registration device 10 displays a registration screen as shown in Fig. 2 on the store clerk display unit 103.

[0021] The registration screen in FIG. 2 is provided with, for example, a product information display area HR10 and a destination device status display area HR11. The product information display area HR10 displays information about the registered products (total number of items, total amount, details of the three most recent products). The destination device status display area HR11 displays the status of each of the four settlement devices 20 to which the registration information is to be sent. According to the destination device status display area HR11 of the registration screen in FIG. 2, settlement machine 1 (one of the settlement devices 20) is on standby, settlement machine 2 (one of the settlement devices 20) is in use, settlement machine 3 (one of the settlement devices 20) is out of service, and settlement machine 4 (one of the settlement devices 20) is on standby (change near end). The registration screen in FIG. 2 is also provided with a subtotal button BT12 that is operated when proceeding to the subtotal (when completing product registration).

[0022] When the subtotal button BT12 is operated on the registration screen of FIG. 2, the registration device 10 displays a subtotal screen as shown in FIG.

[0023] For example, a subtotal information display area HR20 is provided on the subtotal screen in Fig. 3. In the subtotal information display area HR20 on the subtotal screen in Fig. 3 (similar to the subtotal screens in Figs. 8 and 12, and the subtotal discount screens in Figs. 4 to 7, and 9 to 11), "Number of items purchased: 5," "Subtotal (excluding tax 8%) ¥1050," "Consumption tax, etc. 8% ¥84," "Subtotal (including tax 10%) ¥580," and "Total ¥1714" are displayed.

[0024] In this embodiment, for ease of explanation, a distinction is made between the subtotal display screen (Figures 8 and 12) and the subtotal value reduction screen (Figures 4 to 7, 9 to 11), but the subtotal value reduction screen is also one of the subtotal display screens that displays subtotal information in the subtotal information display area HR20.

[0025] "Subtotal (8% excl. tax, ¥1050)" indicates the total amount excluding tax (200+500+200+150=1050) for products with consumption tax (8%) excluded (XX bread, XX lunch box, XX tomatoes (2 pieces), XX tea). "Consumption tax etc. 8% ¥84" indicates the total tax amount (16+40+16+12=84) for products with consumption tax (8%) excluded (XX bread, XX lunch box, XX tomatoes (2 pieces), XX tea). "Subtotal (10% tax included, ¥580)" indicates the total amount including tax (580) for products with consumption tax (10%) etc. included (XX cigarettes). "Total ¥1714" indicates the sum of "Subtotal (8% excl. tax, ¥1050)," "Consumption tax etc. 8% ¥84," "Subtotal (10% tax included, ¥580)," and "Total ¥1714."

[0026] 3, a subtotal price reduction button BT21 is provided for reducing the subtotal price (subtotal discount / subtotal discount). When the subtotal price reduction button BT21 is operated, the registration device 10 displays a subtotal price reduction screen (described later).

[0027] 3 also has a non-eligible product button BT24 that is operated when checking products that are not eligible for the subtotal discount. When the non-eligible product button BT24 is operated, the registration device 10 displays (for example, displays a list on a pop-up screen) the applicable products (products that are set as non-eligible products among the registered products of the customer) in question. In this example, since the applicable product is only XX cigarettes, the registration device 10 displays XX cigarettes when the non-eligible product button BT24 is operated. Note that when there are two or more applicable products, the registration device 10 displays each of the applicable products.

[0028] The small screen of Fig. 3 also has payment machine designation buttons BT61-BT64 that are operated when transmitting registration information. The store clerk operates the payment machine designation button BT61 when transmitting registration information to payment machine 1, operates the payment machine designation button BT62 when transmitting registration information to payment machine 2, operates the payment machine designation button BT63 when transmitting registration information to payment machine 3, and operates the payment machine designation button BT64 when transmitting registration information to payment machine 4. In the scene of Fig. 3, because registration information cannot be transmitted to payment machine 2 (in use) and payment machine 3 (out of service), the payment machine designation button BT62 and the payment machine designation button BT63 are displayed in a display mode (grayed out) indicating that they cannot be operated.

[0029] When the subtotal price reduction button BT21 is operated on the subtotal price reduction screen of FIG. 3, the registration device 10 displays a subtotal price reduction screen as shown in FIG.

[0030] The subtotal price reduction screen in Fig. 4 has a price reduction target amount display area HR30. On the subtotal price reduction screen in Fig. 4, the price reduction target amount display area HR30 displays "Price reduction target amount: ￥1050." This "1050" is the total price (1050) excluding tax of the products subject to price reduction (〇〇 bread, 〇〇 lunch box, 〇〇 cigarettes, 〇〇 tomatoes (2 pieces), 〇〇 tea) registered by the customer, excluding the product not subject to the subtotal price reduction (〇〇 cigarettes).

[0031] The subtotal discount screen in Fig. 4 also has a discount rate selection button BT40 and a discount rate input button BT41 which are operated when applying a subtotal discount. A subtotal discount rate display area HR42 which displays the discount rate of the subtotal is provided. The subtotal discount screen in Fig. 4 also has a discount amount selection button BT43 and a discount amount input button BT44 which are operated when applying a subtotal discount. A subtotal discount amount display area HR45 which displays the discount amount of the subtotal discount is provided.

[0032] The subtotal price reduction screen in FIG. 4 also has a cancel button BT50 which is operated to cancel the subtotal price reduction.

[0033] In addition, if the sixth item in the customer's registered products is XX brand rice (price excluding tax: 3,000 yen), which is a product excluding consumption tax (8%) and is not eligible for subtotal price reduction, the subtotal information display area HR20 on the subtotal price reduction screen in Figure 4 will display "Items purchased: 6," "Subtotal (excluding tax 8%) ¥4,050," "Consumption tax etc. 8% ¥324," "Subtotal (including tax 10%) ¥580," and "Total ¥4,954," and the price reduction amount display area HR30 will display "Price reduction amount: ¥1,050." The "1050" in question is the total amount (1050) excluding tax of the products subject to price reduction (XX bread, XX bento, XX tomato (2 pieces), XX tea, XX brand rice) registered by the customer in question (XX bread, XX bento, XX cigarettes, XX tomatoes (2 pieces), XX tea, XX brand rice) excluding the products not subject to the subtotal price reduction (XX cigarettes, XX brand rice).

[0034] When the discount rate selection button BT40 is operated on the subtotal reduction screen of Fig. 4, the registration device 10 displays a subtotal reduction screen as shown in Fig. 5. On the subtotal reduction screen of Fig. 5, preset discount rates (5%, 10%, 15%, 20%, 25%) are displayed in a selectable pull-down menu (symbol a in the figure). Note that on the subtotal reduction screen of Fig. 5 (similar to the subtotal reduction screen of Fig. 6 and the subtotal reduction screen of Fig. 7), "Discounted amount: ¥1050" is displayed in the discounted amount display area HR30.

[0035] When the discount rate input button BT41 is operated on the subtotal price reduction screen of Fig. 4, the registration device 10 displays the subtotal price reduction screen as shown in Fig. 6. The subtotal price reduction screen of Fig. 6 displays a numeric keypad section (number buttons, clear button, enter button) for inputting the discount rate (symbol b in the figure).

[0036] When 10% is selected in the pull-down display (symbol a) of the subtotal value reduction screen in Fig. 5, or when 10% is entered in the numeric keypad section (symbol b) of the subtotal value reduction screen in Fig. 6, the registration device 10 displays a subtotal value reduction screen as shown in Fig. 7. The 10% selected on the subtotal value reduction screen in Fig. 5, or the 10% entered in the subtotal value reduction screen in Fig. 6, is displayed in the subtotal discount rate display area HR42 of the subtotal value reduction screen in Fig. 7.

[0037] Also, on the subtotal markdown screen in Fig. 7, a markdown amount display area HR31 is provided below the markdown amount display area HR30. On the subtotal markdown screen in Fig. 7, the markdown amount display area HR31 displays "Discount amount: -￥105." The "105" is 10% (105) of the total price (1050) excluding tax for the customer's markdown items (XX bread, XX lunch box, XX tomato (2 pieces), XX tea).

[0038] In addition, the subtotal price reduction screen in FIG. 7 (similar to the subtotal price reduction screen in FIG. 11) has a Cancel button BT50 which is operated when canceling the subtotal price reduction (subtotal discount in FIG. 7, subtotal discount in FIG. 11), as well as a Confirm button BT51 which is operated when confirming the subtotal price reduction (subtotal discount in FIG. 7, subtotal discount in FIG. 11).

[0039] When the Confirm button BT51 is operated on the subtotal discount screen in Fig. 7, the registration device 10 displays a subtotal screen as shown in Fig. 8. In the subtotal information display area HR20 of the subtotal screen in Fig. 8, in addition to the information displayed on the subtotal screen in Fig. 3 ("Number of items purchased: 5", "Subtotal (excluding tax 8%) ¥1050", "Consumption tax etc. 8% ¥84", "Subtotal (including tax 10%) ¥580", and "Total ¥1714"), "Discount / Price reduction total - ¥105" (symbol c), "Discount / Price reduction total ¥1600" (symbol d), and "Subtotal discount - ¥105" (symbol e) are displayed.

[0040] "Subtotal discount - ¥105" (symbol e) indicates "Discount amount: -¥105" in the markdown amount display area HR31 on the subtotal markdown screen in Figure 7. "Discount / markdown total - ¥105" (symbol c) is the total markdown amount, and since only "Subtotal discount - ¥105" (symbol e) is present here, the amount is the same. The "1600" in "Discount / markdown total ¥1600" (symbol d) is the amount calculated by "(1050-105) x 1.08 + 580 = 1600".

[0041] When the discount amount selection button BT43 is operated on the subtotal discount screen of Fig. 4, the registration device 10 displays a subtotal discount screen as shown in Fig. 9. In the subtotal discount screen of Fig. 9, preset discount amounts (100 yen, 300 yen, 500 yen, 1000 yen, 1500 yen) are displayed in a selectable pull-down menu (symbol f in the figure). In addition, in the subtotal discount screen of Fig. 9 (similar to the subtotal discount screen of Fig. 10 and the subtotal discount screen of Fig. 11), "Discount target amount: ￥1050" and "(maximum discountable amount)" are displayed in the discount target amount display area HR30. In addition, because it exceeds the discount target amount (maximum discountable amount) of ￥1050, 1500 yen is displayed in a display mode (grayed out) in the pull-down menu to indicate that it cannot be selected.

[0042] When the discount amount input button BT44 is operated on the subtotal discount screen of Fig. 4, the registration device 10 displays a subtotal discount screen as shown in Fig. 10. The subtotal discount screen of Fig. 10 displays a numeric keypad section for inputting the discount amount in numerical value (symbol g in the figure).

[0043] When 300 yen is selected in the pull-down display (symbol f) of the subtotal reduction screen in Fig. 9, or when 300 yen is entered in the numeric keypad section (symbol g) of the subtotal reduction screen in Fig. 10, the registration device 10 displays a subtotal reduction screen as shown in Fig. 11. The subtotal discount amount display area HR45 of the subtotal reduction screen in Fig. 11 displays 300 yen selected on the subtotal reduction screen in Fig. 9, or 300 yen entered in the subtotal reduction screen in Fig. 10.

[0044] In addition, the subtotal markdown screen in Fig. 11 has a markdown amount display area HR31 below the markdown target amount display area HR30. In the subtotal markdown screen in Fig. 11, the markdown amount display area HR31 displays "Discount amount: -¥300".

[0045] When the Confirm button BT51 is operated on the subtotal discount screen in Fig. 11, the registration device 10 displays a subtotal screen as shown in Fig. 12. In the subtotal information display area HR20 of the subtotal screen in Fig. 12, in addition to the information displayed on the subtotal screen in Fig. 3, "Discount / Market Reduction Total - ¥300" (symbol h), "Discount / Market Reduction Total ¥1390" (symbol i), and "Subtotal Mark Reduction - ¥300" (symbol j) are displayed.

[0046] "Subtotal discount - ¥300" (code j) indicates "Discount amount: -¥300" in the discount amount display area HR31 on the subtotal discount screen in Figure 11. "Discount / discount total - ¥300" (code h) is the total discount, and since only "Subtotal discount - ¥300" (code j) is present here, the amount is the same. "1390" in "Discount / discounted total ¥1390" (code i) is the amount calculated by "(1050-300) x 1.08 + 580 = 1390".

[0047] (Customer side display) Although the display on the clerk side (clerk display unit 103) of registration device 10 has been described using Figs. 2 to 12, the display on the customer side (customer display unit 106) of registration device 10 may be as follows.

[0048] When the registration device 10 is displaying the subtotal screen on the store clerk display unit 103, it may display all or part of the information displayed in the subtotal information display area HR20 of the subtotal screen on the customer display unit 106.

[0049] For example, when the registration device 10 displays the subtotal information display area HR20 of the subtotal screen of Figure 3 on the clerk-side display unit 103, it may display all of the information displayed in the subtotal information display area HR20 of the subtotal screen of Figure 3 ("Items purchased: 5 items," "Subtotal (excluding tax 8%) ¥1,050," "Consumption tax etc. 8% ¥84," "Subtotal (including tax 10%) ¥580," and "Total ¥1,714") on the customer-side display unit 106, or it may display only a portion of the information ("Items purchased: 5 items," "Total ¥1,714") on the customer-side display unit 106.

[0050] Also, for example, when the registration device 10 displays the subtotal information display area HR20 of the subtotal screen of Figure 8 on the store clerk display unit 103, it may display all of the information displayed in the subtotal information display area HR20 of the subtotal screen of Figure 8 ("Number of items purchased: 5," "Subtotal (excluding tax 8%) ¥1,050," "Consumption tax etc. 8% ¥84," "Subtotal (including tax 10%) ¥580," "Total ¥1,714," "Total including discounts and markdowns - ¥105," "Total after discounts and markdowns ¥1,600," and "Subtotal discount - ¥105") on the customer display unit 106, or it may display only a portion of the information ("Number of items purchased: 5," "Total ¥1,714," "Total including discounts and markdowns - ¥105," "Total after discounts and markdowns ¥1,600") on the customer display unit 106.

[0051] For example, when the registration device 10 displays the subtotal information display area HR20 of the subtotal screen of Figure 12 on the store clerk display unit 103, it may display all of the information displayed in the subtotal information display area HR20 of the subtotal screen of Figure 12 ("Items purchased: 5 items," "Subtotal (excluding tax 8%) ¥1,050," "Consumption tax etc. 8% ¥84," "Subtotal (including tax 10%) ¥580," "Total ¥1,714," "Total including discounts and markdowns - ¥300," "Total after discounts and markdowns ¥1,390," and "Subtotal markdown - ¥300") on the customer display unit 106, or it may display only a portion of the information ("Items purchased: 5 items," "Total ¥1,714," "Total including discounts and markdowns - ¥300," and "Total after discounts and markdowns ¥1,390") on the customer display unit 106.

[0052] When the registration device 10 displays the subtotal price reduction screen on the store clerk display unit 103, in addition to all or part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen, it may also display information displayed in the price reduction target amount display area HR30, the price reduction amount display area HR31, the subtotal discount rate display area HR42, and the subtotal discount amount display area HR45.

[0053] For example, when the registration device 10 displays the subtotal price reduction screen of Figure 4 on the store clerk display unit 103, in addition to all or part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen of Figure 4, the registration device 10 may also display the information displayed in the markdown amount display area HR30 of the subtotal price reduction screen of Figure 4 ("Markdown amount: ¥1,050") on the customer display unit 106.

[0054] For example, when the registration device 10 displays the subtotal price reduction screen of FIG. 5 or FIG. 6 on the store clerk display unit 103, in addition to all or a part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen of FIG. 5 or FIG. 6, the registration device 10 may also display the information displayed in the discount amount display area HR30 of the subtotal price reduction screen of FIG. 5 or FIG. 6 ("Discount amount: ¥1,050") on the customer display unit 106.

[0055] For example, when the registration device 10 displays the subtotal price reduction screen of Figure 7 on the store clerk display unit 103, in addition to all or a part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen of Figure 7, the registration device 10 may also display on the customer display unit 106 the information displayed in the markdown amount display area HR30 of the subtotal price reduction screen of Figure 7 ("Discount amount: ¥1050"), the information displayed in the subtotal discount rate display area HR42 (the discount rate "10%)), and the information displayed in the markdown amount display area HR31 ("Discount amount: -¥105").

[0056] For example, when the registration device 10 displays the subtotal price reduction screen of FIG. 9 or 10 on the store clerk display unit 103, in addition to all or a part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen of FIG. 9 or 10, the registration device 10 may also display the information displayed in the discount amount display area HR30 of the subtotal price reduction screen of FIG. 9 or 10 ("Discount amount: 1,050 yen", "(Maximum discountable amount)") on the customer display unit 106.

[0057] For example, when the registration device 10 displays the subtotal price reduction screen of FIG. 11 on the store clerk display unit 103, in addition to all or a part of the information displayed in the subtotal information display area HR20 of the subtotal price reduction screen of FIG. 11, the registration device 10 may also display on the customer display unit 106 the information displayed in the discount amount display area HR30 of the subtotal price reduction screen of FIG. 11 ("Discount amount: ¥1,050", "(Maximum discountable amount)"), the information displayed in the subtotal discount amount display area HR45 (the discount amount "¥300"), and the information displayed in the discount amount display area HR31 ("Discount amount: -¥300").

[0058] When the registration device 10 is displaying the sub-plan screen or the subtotal markdown screen on the store clerk display unit 103 (when the non-eligible product button BT24 is displayed on the store clerk display unit 103), the registration device 10 may also display the non-eligible product button BT24 on the customer display unit 106.

[0059] The registration device 10 may display products that are not eligible for the subtotal discount instead of displaying the not eligible product button BT24 on the store clerk display unit 103. In other words, the registration device 10 may not place the not eligible product button BT24 on the store clerk display unit 103 and may display products that are not eligible for the subtotal discount from the beginning. The registration device 10 may display products that are not eligible for the subtotal discount instead of displaying the not eligible product button BT24 on the customer display unit 106. In other words, the registration device 10 may not place the not eligible product button BT24 on the customer display unit 106 and may display products that are not eligible for the subtotal discount from the beginning. The registration device 10 may display the not eligible product button BT24 on the store clerk display unit 103 and may display products that are not eligible for the subtotal discount from the beginning on the customer display unit 106.

[0060] (Other devices) The above describes the display of the registration device 10 (the store clerk display unit 103, the customer display unit 106), but other devices may similarly display the amount subject to the discount, products not subject to the subtotal discount, etc.

[0061] For example, the registration and settlement device 30 may display on the clerk display unit 303 screens that the registration device 10 displays on the clerk display unit 103 (the registration screen in Figure 2, the subtotal screens in Figures 3, 8, and 12, and the subtotal markdown screens in Figures 4 to 7, and 9 to 11), and may display on the customer display unit 306 screens that the registration device 10 displays on the customer display unit 106.

[0062] For example, when in normal mode, the registration and settlement device 50 may display on the clerk display unit 503 a screen that the registration device 10 displays on the clerk display unit 103, and may display on the customer display unit 506 a screen that the registration device 10 displays on the customer display unit 106.

[0063] The registered settlement device 30 executes settlement processing in its own device (non-cash settlement unit 308, cash settlement unit 309 of its own device) using registration information registered in its own device for registering products, but in addition to executing settlement processing in its own device, it may transmit registration information to another device to have the other device execute settlement processing. The same applies to the registered settlement device 50 in normal mode.

[0064] When a specific settlement machine is specified (for example, when the settlement machine designation button BT61 that designates settlement machine 1 is operated), the registered settlement device 30 executes settlement processing on its own device, and when another settlement machine is specified (for example, when the settlement machine designation buttons BT62 to BT64 that designate settlement machines 2 to 4 are operated), it may transmit registration information to another device. The same applies to the registered settlement device 50 in normal mode.

[0065] The embodiment has been described above. According to the registration device 10 (the registration settlement device 30, the registration settlement device 50) of the embodiment, the subtotal discount can be suitably implemented.

[0066] For example, in the past, when trying to discount the subtotal, if the registered items included items that were not eligible for the subtotal discount, problems could arise such as taking time to operate or being unable to explain to the customer. In other words, it would be fine if all store clerks correctly recognized the items that were not eligible for the subtotal discount (recognizing that there are items that are not eligible for the subtotal discount, and recognizing which items are not eligible for the subtotal discount), but if the store clerk did not recognize the items properly, there were times when the price reduction operation resulted in repeated operation errors (for example, an error when a discount amount that exceeds the discount amount is entered or selected) or when the discount amount could not be properly explained (for example, an explanation of why the discount amount is less when the discount amount = the total amount than when the discount amount < the total amount).

[0067] In contrast, the registration device 10 (registration and settlement device 30, registration and settlement device 50) provides necessary information about the subtotal discount in an appropriate manner (displayed on the same screen when necessary and easily visible) (Figs. 3 to 12), so the above-mentioned problems do not occur. In other words, it becomes possible to notice an error before it occurs during operation, to easily respond to inquiries from customers or to proactively explain the situation to customers, and to reduce the burden on store clerks and customer dissatisfaction.

[0068] (Variations, etc.) Although the embodiment has been described above, the device configuration, data configuration, processing flow, display and output aspects, etc. can be appropriately changed, for example, as shown in the following (1) to (6). In addition, the following (1) to (6) may be appropriately combined with each other.

[0069] (1) In the examples of Figures 9 to 11, the examples have been described in which "Discount Amount" and "Maximum Discountable Amount" are displayed in the discount amount display area HR30. However, since "Discount Amount" and "Maximum Discountable Amount" indicate the same amount, in the case of a subtotal discount, either "Discount Amount" or "Maximum Discountable Amount" may be displayed in the discount amount display area HR30.

[0070] (2) The subtotal price reduction button BT21 may be a pull-down button, like the discount rate selection button BT40 and the discount amount selection button BT43. In other words, the registration device 10 (as well as the registration settlement device 30 and the registration settlement device 50 in the normal mode) may display a subtotal price reduction screen when a pull-down operation for “subtotal price reduction” is performed.

[0071] (3) In the above embodiment, an example was described in which either a subtotal discount or a subtotal markdown was specified (selected) on the subtotal markdown screen (e.g., see FIG. 4). However, either a subtotal discount or a subtotal markdown may also be specified (selected) on the subtotal price reduction screen (e.g., see FIG. 3).

[0072] For example, the registration device 10 (as well as the registration and settlement device 30 and the registration and settlement device 50 in normal mode) may display a subtotal discount button BT22 (not shown) and a subtotal discount button BT23 (not shown) on the subtotal display screen instead of the subtotal discount button BT21. The registration device 10 (as well as the registration and settlement device 30 and the registration and settlement device 50 in normal mode) may display a subtotal discount screen provided with buttons related to subtotal discounts (discount rate selection button BT40, discount rate input button BT41, total discount rate display area HR42) when the subtotal discount button BT22 (not shown) is operated, and may display a subtotal discount screen provided with buttons related to subtotal discounts (discount amount selection button BT43, discount amount input button BT44, subtotal discount amount display area HR45) when the subtotal discount button BT23 (not shown) is operated.

[0073] For example, the registration device 10 (as well as the registration and settlement device 30 and the registration and settlement device 50 in normal mode) may display a pull-down button on the subtotal screen that allows the selection of a subtotal discount or a subtotal markdown. When a subtotal discount is selected, the registration device 10 (as well as the registration and settlement device 30 and the registration and settlement device 50 in normal mode) may display a subtotal markdown screen with buttons related to the subtotal discount, and when a subtotal markdown is selected, may display a subtotal markdown screen with buttons related to the subtotal markdown.

[0074] (4) In the above embodiment, an example was described in which products not eligible for the subtotal discount were displayed. However, products eligible for the subtotal discount may be displayed instead of or in addition to the products not eligible for the subtotal discount.

[0075] For example, when the non-eligible product button BT24 is operated, the registration device 10 (as well as the registration settlement device 30 and the registration settlement device 50 in normal mode) may display each of the customer's registered products in a manner that distinguishes whether the product is eligible for the subtotal discount or not. The same applies to the display on the customer side.

[0076] Also, for example, the registration device 10 (as well as the registration settlement device 30 and the registration settlement device 50 in normal mode) may display eligible products BT25 (not shown) instead of or in addition to the excluded product button BT24, and when the excluded product button BT24 is operated, may display products that are set as not eligible for the subtotal price reduction among the registered products of the customer, and when the eligible product button BT25 (not shown) is operated, may display products that are not set as not eligible for the subtotal price reduction among the registered products of the customer (i.e., products that are eligible for the subtotal price reduction). The same applies to the display on the customer side.

[0077] Also, for example, the registration device 10 (as well as the registration settlement device 30 and the registration settlement device 50 in normal mode) may display, from the beginning, without any special operation, whether each of the customer's registered products is subject to a subtotal discount or not, in a distinguishable manner. The same applies to the display on the customer side.

[0078] (5) Although not explained in the above embodiment, the "+" button located above the product information display area HR10 on the registration screen (FIG. 2) is a button that is operated when starting to register another (next) customer (transaction). When the "+" button is operated, the registration device 10 (and similarly for other devices) generates a tab for a new transaction (a tab for each product information display area HR10) (for example, in the scene of FIG. 2, tab "2" is generated in addition to tab "1"). Also, customers (transactions) can be switched by operating the tabs.

[0079] (6) Some or all of the functions (input / output, storage, processing (including judgment)) of each device (e.g., registration device 10, settlement device 20, registration settlement device 30, registration settlement device 40, registration settlement device 50) may be realized in other devices different from the device described as the entity that executes the function. As an example, instead of each device, another device (e.g., a cloud server) may calculate the total price of goods, etc. Each device may function as a so-called thin client specialized for input / output interfaces, etc. For example, a cloud server may execute a program for controlling the operation of the registration device 10 (registration settlement device 30, registration settlement device 50 in normal mode), and the registration device 10 (registration settlement device 30, registration settlement device 50 in normal mode) may display a screen (the screen of Figures 2 to 12) by a browsing function.

[0080] <Summary of the embodiment> [Technical field] The present invention relates to a data processing device and a program. [Background technology] 2. Description of the Related Art There is known a POS terminal that, when a barcode of a product is scanned, determines whether the product is eligible for a discount and then applies a discount (see, for example, Patent Document 1). [Prior art document] [Patent documents] [Patent Document 1] JP 2018-180929 A [Summary of the Invention] [Problem to be solved by the invention] The present invention provides a method for reducing a price by a certain amount, such as a price reduction by adding a price to a subtotal, and a method for reducing a price by adding a price to a subtotal. [Means for solving the problem]

[0081] (1) One aspect for solving the above-mentioned problem is a registration means for registering products, and a display means for displaying a total price of the products registered by the registration means, and the display means displays the total price (e.g., the amount to be displayed in a subtotal information display area HR20) and information regarding a price reduction (e.g., a subtotal discount) for all or a part of the total price (e.g., a subtotal discount button BT21, a subtotal discount button BT22 (not shown), a subtotal discount button BT23 (not shown), an excluded product button BT24, an eligible product button BT25, a discount button BT26, a discount button BT27, a discount button BT28, a discount button BT29, a discount button BT30, a discount button BT31, a discount button BT32, a discount button BT33, a discount button BT34, a discount button BT35, a discount button BT36, a discount button BT37, a discount button BT38, a discount button BT39, a discount button BT40, a discount button BT41, a discount button BT42, a discount button BT43, a discount button BT44, a discount button BT45, a discount button BT46, a discount button BT47, a discount button BT48, a discount button BT49, a discount button BT41, a discount button BT41, a discount button BT42, a discount button BT43, a discount button BT44, a discount button BT45, a discount button BT46, a discount button BT47, a discount button BT48, a discount button BT49, a discount button BT49, a discount button BT41, a discount button BT41, a discount button BT42, a discount button BT43, a discount button BT44, a discount button BT45, a discount button BT46, a discount button BT47, a discount button BT This data processing device (e.g., registration device 10, registration settlement device 30, registration settlement device 50) is characterized by displaying the following on the same screen (see Figures 3 to 12): information displayed in markdown amount display area HR30, information displayed in markdown amount display area HR31, discount rate selection button BT40, discount rate input button BT41, information displayed in subtotal discount rate display area HR42, discount amount selection button BT43, discount amount input button BT44, and information displayed in subtotal discount amount display area HR45. According to the data processing device of (1), subtotal discounts can be suitably implemented.

[0082] (2) The data processing device described in (1) is characterized in that it is provided with a reception means for receiving an instruction for the price reduction (e.g., a subtotal discount button BT22 (not shown), a discount rate selection button BT40, a discount rate input button BT41), and when the reception means receives an instruction for a discount as the instruction for the price reduction, the display means displays the discount amount subject to the discount as information relating to the price reduction (e.g., see Figures 5 to 7). According to the data processing device of (2), a subtotal discount can be suitably implemented.

[0083] (3) A data processing device as described in (1) or (2) is provided with a reception means for receiving an instruction for the price reduction (e.g., a subtotal discount button BT23 (not shown), a discount amount selection button BT43, a discount amount input button BT44), and when the reception means receives an instruction for the price reduction as an instruction for the price reduction, the display means displays at least one of the discount amount that is the subject of the discount and the discountable amount that is the upper limit of the discount as information regarding the price reduction (e.g., see Figures 9 to 11). According to the data processing device of (3), a subtotal discount can be suitably implemented.

[0084] (4) The data processing device according to any one of (1) to (3), wherein the display means displays information about products that are not subject to the price reduction as the information about the price reduction. According to the data processing device of (4), subtotal discounts can be suitably implemented.

[0085] (5) One aspect for solving the above-mentioned problems is a program that causes a computer to function as a data processing device having a display unit (e.g., registration device 10, registration settlement device 30, registration settlement device 50), which causes the computer to function as a registration means for registering products and a display control means for displaying on a display unit the total price of the products registered by the registration means, and which is characterized in that the display control means displays on the same screen the total price and information regarding a price reduction targeting all or part of the total price. According to the program (5), subtotal discounts can be implemented effectively.

[0086] In addition, a program for realizing the functions of each device described above (for example, the registration device 10, the settlement device 20, the registration settlement device 30, the registration settlement device 40, the registration settlement device 50, etc.) may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing of each device. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including the Internet, a WAN, a LAN, a dedicated line, and other communication lines. In addition, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, an optical magnetic disk, a ROM, a CD-ROM, and a storage device such as a hard disk built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. In addition, the recording medium also includes a recording medium provided inside or outside and accessible from a distribution server to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by the terminal device. In other words, the format in which the program is stored in the distribution server does not matter as long as it can be downloaded from the distribution server and installed in a format executable by the terminal device. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a memory that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network. The above program may also be for realizing part of the above-mentioned functions.Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program).
