Description

[Technical field]

[0001] The present invention relates to a product sales data processing device and a program. [Background technology]

[0002] Conventionally, when foreign tourists or the like purchase goods at domestic stores, certain categories of goods, such as consumables, may be exempt from tax if the goods are within a certain amount. To be eligible for tax exemption, the shopper must go through a tax exemption procedure. During the tax exemption procedure, for example, the shop assistant may package the goods and attach the necessary documents to the passport.

[0003] A related technology is a cash register that registers products into tax-free categories for consumables and general goods, and prints the tax-free category of the product information on a receipt by decoding the barcode attached to the product (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-232773 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the conventional technology, for example, since a product is registered in a tax-free category that is recorded in advance in a product master or the like, it is not possible to register a product in a desired tax-free category, and thus there is a problem that flexible tax-free processing cannot be performed.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a technique capable of carrying out flexible tax exemption processing. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, one aspect of the present invention is a product sales data processing device that comprises a registration means for registering products, a classification change acceptance means for accepting a change to the tax-free classification of a product registered in the registration means, and a classification change processing means for, when a change to the tax-free classification is accepted by the classification change acceptance means, changing the tax-free classification of the product registered in the registration means to the accepted tax-free classification, wherein, when the classification change processing means changes the tax-free classification of a product registered in the registration means, it displays on a display unit a fact that the tax-free classification of the product has been changed, the tax-free classification before the change, and the tax-free classification after the change. In order to solve the above-mentioned problems, another aspect of the present invention is a program that causes a computer of a product sales data processing device to function as a registration means for registering products, a classification change acceptance means for accepting a change to the tax-free classification of products registered in the registration means, and a classification change processing means for, when a change to the tax-free classification is accepted by the classification change acceptance means, changing the tax-free classification of the product registered in the registration means to the accepted tax-free classification, wherein the classification change processing means, when changing the tax-free classification of a product registered in the registration means, displays on a display unit a fact that the tax-free classification of the product has been changed, the tax-free classification before the change, and the tax-free classification after the change.

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. (Embodiment) Fig. 1 is a network configuration diagram of a POS (Point Of Sales) system according to an embodiment of the present invention. The POS system 1 shown in Fig. 1 is an example of a product sales data processing system. As shown in Fig. 1, the POS system 1 includes a store controller 2, a POS register 3, and each device connected by wire or wirelessly via a communication line 6 such as a LAN (Local Area Network) or a WAN (Wide Area Network). Note that a plurality of POS registers 3 are installed in a store, but there are also cases where only one POS register 3 is installed.

[0010] The store controller 2 is a management device that performs administrative processes such as managing product information, tallying up sales results of duty-free shops, and managing customer information. The store controller 2 stores a product master (see FIG. 4) that stores product information for each product. Details will be described later, but the product master is product information that associates, for example, classification, product code, product name, price, etc. for each product.

[0011] The POS register 3 is an example of a product sales data processing device. The POS register 3 is a cash register device that includes a product registration processing unit and an accounting processing unit. The product registration processing unit executes product registration processing of products to be purchased by a customer. The accounting processing unit executes accounting processing (settlement processing) based on the product sales data registered by the product registration processing unit.

[0012] Here, customers include non-residents who are temporarily staying in Japan. Non-residents include foreign tourists and Japanese nationals who have temporarily returned to Japan. Non-residents hold a passport or similar document. When non-residents purchase goods at domestic stores, they may be exempt from tax on certain goods in the tax-free category, such as consumables, if the amount is within a specified range (tax-free applicable amount).

[0013] To be eligible for tax exemption, a customer must go through tax exemption procedures at the store. In tax exemption procedures, for example, a store clerk may pack the product and affix necessary documents to the customer's passport. Necessary documents include a purchase record slip and a purchaser's pledge. In place of such tax exemption procedures, for example, there may be cases where the store explains the necessary matters to the customer without creating a purchaser's pledge slip or purchase record slip, and the store transmits purchase record information to a specified organization (for example, the National Tax Agency).

[0014] When carrying out the tax exemption procedure, the POS register 3 executes product registration processing and accounting processing for the goods eligible for tax exemption. Goods eligible for tax exemption are divided into, for example, general goods and consumables. General goods include, for example, home appliances, kimonos, clothes, bags, etc. General goods are eligible for tax exemption on the condition that the total amount of sales of general goods to the same non-resident at the same store in one day is 5,000 yen or more.

[0015] Examples of consumables include food, beverages, medicines, cosmetics, etc. Consumables are eligible for tax exemption if the total amount of sales of consumables to one non-resident at one store in one day is between 5,000 yen and 500,000 yen. When consumables are purchased as tax-exempt items, the store clerk packs them in special packaging so that they cannot be used within the country.

[0016] In particular, if certain conditions are met, it is possible to register a product that is originally classified as a general item as a tax-free consumable item. Specifically, even if the product is classified as a general item, it is possible to register the product as a tax-free consumable item, provided that the total amount of the product, including the consumable item, is 5,000 yen or more and 500,000 yen or less.

[0017] The POS register 3 can register and settle products in a tax-free manner in addition to the usual (normal processing) registration and settlement of products. In the tax-free processing, for example, products are registered according to tax-free categories, and the settlement is made with tax exemption according to the total amount of the products registered in each tax-free category. The registration and settlement terminal 3 can also create and print tax-free documents.

[0018] Any of the multiple POS registers 3 in the POS system 1 may be used as a service counter terminal. To give more specific details about the service counter terminal, the service counter terminal accepts shipments and returns of products purchased by customers, orders for products, and sales of gift certificates. The service counter terminal also receives and manages transaction information indicating the products and amounts for each transaction at each POS register 3 from each POS register 3. The service counter terminal also manages transaction information for each transaction for which tax exemption processing has been performed at each POS register 3 (hereinafter sometimes referred to as "tax-exempt transactions").

[0019] Each device in the POS system 1 may include a mobile terminal. The mobile terminal is a terminal device such as a mobile phone or a smartphone carried by a store clerk. The mobile terminal may be lent to each store clerk or may be owned by each store clerk. In response to a call request from the POS register 3 (including the service counter terminal), the mobile terminal notifies the request or receives the call.

[0020] (Example of the appearance of the POS register 3) Fig. 2 is an explanatory diagram showing an example of a schematic external appearance of the POS register 3. In this embodiment, Fig. 2(a) is a front view of the POS register 3 as seen from the operator (store clerk) side. Fig. 2(b) is a side view. As shown in Figs. 2(a) and 2(b), the POS register 3 comprises a store clerk display unit 21, a key operation unit 22, a customer display unit 23, a card payment unit 24, and a printing unit 25.

[0021] The clerk display unit 21 is a touch display operated by the clerk. The clerk display unit 21 displays preset keys and the like, displays various information to the clerk, and accepts various inputs from the clerk.

[0022] The key operation unit 22 is a keyboard provided with various keys. The various keys are operation keys (hardware keys or buttons) such as numeric keys for inputting quantities and prices, keys corresponding to products for registering products, and a closing key for closing the transaction. The key operation unit 22 accepts various inputs from store clerks.

[0023] The customer display unit 23 is a touch display that displays various information to the customer. The customer display unit 23 displays various information to the customer and accepts various inputs from the customer. For example, when a product that requires age verification is registered, the customer display unit 23 displays an age verification screen and accepts age verification from the customer.

[0024] The card payment unit 24 is a payment mechanism using a contact type card (e.g., a magnetic card). Cards read by the card payment unit 24 include credit cards, point cards, prepaid cards, etc. However, the card payment unit 24 may be a payment mechanism using a non-contact type card (IC card) instead of or in addition to a contact type card.

[0025] The printing unit 25 is a printer device that prints out detailed descriptions of the purchased items as various slips (receipts).

[0026] Fig. 3 is a block diagram showing an example of a hardware configuration of the POS register 3. As shown in Fig. 3, the POS register 3 includes, in addition to the components shown in Fig. 2, a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, a communication unit 34, a scanner unit 35, and a drawer 36. The components shown in Fig. 3 are connected to each other via an internal bus and a communication line.

[0027] The CPU 31 is a central processing unit, and controls the operation of the registered settlement terminal 3 by reading and executing programs stored in the ROM 32 . The ROM 32 is a read-only memory, and stores various types of information used by the CPU 31, including programs.

[0028] The RAM 33 is a read / write memory and stores various information. For example, the RAM 33 stores information acquired from the outside and information generated in the process. The information acquired from the outside is, for example, a product master acquired from the store controller 2. The information generated in the process is, for example, registration information generated in a registration process for registering products and settlement information generated in a settlement process for settling the purchased products. The POS register 3 may include another storage unit such as a hard disk in addition to the RAM 33.

[0029] The communication unit 34 transmits and receives information between the store controller 2 and other POS registers 3.

[0030] The scanner unit 35 optically reads code information (for example, two-dimensional codes such as barcodes) attached to products and store clerk codes attached to store clerk nametags. The scanner unit 35 also reads code information written on product catalogs and product order sheets. In addition to the above, the scanner unit 35 also reads codes printed on bills, coupons, and various cards.

[0031] The drawer 36 is a storage unit that stores bills and coins received from a customer. The drawer 36 is designed to be pulled out in response to the operation of the key operation unit 22. The audio output unit 37 outputs audio. For example, the audio output unit 37 outputs a sound when a product is read, an operation sound of the key operation unit 22, a warning sound, audio guidance, and the like.

[0032] The POS register 3 also includes an automatic change machine (not shown). The automatic change machine is a mechanism for making settlements with cash. The automatic change machine has a deposit slot for banknotes and coins, and a change outlet for banknotes and coins. The automatic change machine calculates the amount of money inserted into the deposit slot, and the change amount, which is the difference between the amount inserted and the purchase amount, and ejects the change from the change outlet. The deposit slot and change outlet may be positioned facing the customer and operated by the customer.

[0033] (About the data structure of product master data) Fig. 4 is an explanatory diagram showing an example of the data configuration of the product master. The product master shown in Fig. 4 is stored in the store controller 2. Note that the product master does not necessarily have to be stored in the store controller 2, but may also be stored in the POS register 3. In this case, the POS register 3 may receive the product master from the store controller 2 and store the received product master.

[0034] In Fig. 4, the product master is information that associates each item of a major category, a medium category, a minor category, a product code, a product name, a tax-free category, a price, and a change in the tax-free category. Note that the items shown in Fig. 4 are only an example, and other items may be included, such as an item indicating a discount rate in the case of a discount, or an item indicating whether age verification is required.

[0035] To explain the product master in more detail, the major category is the highest category. The medium category is a category smaller than the major category. The small category is a category even smaller than the medium category. The size relationship between the categories indicates that the smaller the category, the easier it is to identify the product. The product code is identification information that is uniquely assigned to the product. The product name is the name of the product. The tax-free category is stored as either a consumables category, a general goods category, or "-" which indicates neither category. Products that are not classified as tax-free categories correspond to the provision of a service such as labor costs. The price is the selling price of the product or service. In FIG. 4, the price indicates the price excluding tax.

[0036] Furthermore, "change of tax-free category" indicates whether or not the tax-free category can be changed. For example, for general goods, the tax-free category can be changed to consumables. For consumables and products without a tax-free category, the tax-free category cannot be changed. Note that, among general goods, there may be some products that can be changed to consumables and some that cannot. In other words, there may be some general goods that are set so that they cannot be changed from general goods to consumables and registered.

[0037] (Data structure of transaction information) 5 is an explanatory diagram showing an example of the data configuration of transaction information stored in the POS register 3. The transaction information is generated for each transaction by the POS register 3 using the product master stored in the store controller 2.

[0038] As shown in FIG. 5, the transaction information includes a receipt #, date and time, product code, product name, price, and tax-free category. The receipt # is unique identification information assigned to a receipt issued for each transaction. The date and time is the date and time when the transaction took place. The product code is identification information for the registered product. The product name is the name of the registered product. The price is the price including tax of the registered product. The tax-free category is either a consumable item, a general item, or an item that does not fall into either category. In addition to the items shown in the figure, the transaction information may also include product classification, tax-inclusive price, tax rate (consumption tax rate), etc.

[0039] Here, the transaction information of receipt # "000001" will be specifically explained. The transaction information of receipt # "000001" indicates that five products were registered on the date and time "May 13, 2019". The information indicating the five products includes the product code, product name, price, and tax-free category.

[0040] (An example of the screen displayed on the POS register during tax exemption processing) Next, an example of the screen displayed on the clerk display unit 21 of the POS register in the duty-free process will be described. Note that the image displayed on the clerk display unit 21 described below may also be displayed on the customer display unit 23. Also, the language displayed on the customer display unit 23 may be the language corresponding to the customer (the customer's native language). The designation of the language corresponding to the customer may be accepted by the operation of the clerk from the clerk display unit 21, or may be accepted by the operation of the customer from the customer display unit 23. Also, when accepting the designation of the language corresponding to the customer, a screen for accepting the language designation may be displayed on the clerk display unit 21 or the customer display unit 23.

[0041] (An example of the screen transition in the case of performing duty-free processing) Using FIGS. 6 to 8, an example of the screen transition of the screen displayed on the clerk display unit 21 of the POS register 3 in the duty-free process will be described. FIG. 6 is an explanatory diagram showing the transition from the normal processing screen to the duty-free processing screen at the time of registering a product. FIG. 6(A) shows the screen during normal processing. As shown in FIG. 6(A), information regarding the registered products is displayed in the registered product display area 601, the registered product list area 602, and the total display area 603 on the clerk display unit 21.

[0042] The registered product display area 601 is an area where the product most recently registered in the current transaction is displayed. The registered product list area 602 is an area where a list of the products registered in the current transaction is displayed. The total display area 603 is an area where the total number and total amount of the products registered in the current transaction are displayed.

[0043] The character "in" is displayed in association with the amount displayed in each of the areas 601 to 603, indicating that all are the internal tax. Note that the amount displayed in each of the areas 601 to 603 may be displayed in the external tax. In this case, the character "out" indicating the external tax may be displayed in association with the amount displayed in each of the areas 601 to 603. Whether to use the internal tax notation or the external tax notation may be switchable.

[0044] Also, in FIG. 6(A), on the clerk display unit 21, a duty-free declaration button 611, a duty-free category change button 612, and a subtotal button 613 are displayed. The duty-free declaration button 611 is a button for starting the duty-free process. The duty-free declaration button 611 is always displayed, for example, in the mode of registering goods, and accepts the clerk's operation before starting the registration of goods or during the registration of goods. If the duty-free declaration button 611 is touched again during the execution of the duty-free process, the process returns to the normal process.

[0045] The duty-free category change button 612 is a button for accepting the change of the duty-free category. When the duty-free category change button 612 is pressed (touched), the screen transitions to a screen where the change of the duty-free category is possible. The details of the screen where the change of the duty-free category is possible will be described later with reference to FIG. 8.

[0046] When the subtotal button 613 is operated, the screen transitions to the subtotal screen and accepts the settlement process. When the screen shown in FIG. 6(A) is displayed, for example, if a foreign traveler customer requests the clerk to perform duty-free and the clerk presses the duty-free declaration button 611, the screen shown in FIG. 6(B) is transitioned to.

[0047] FIG. 6(B) shows the screen during the duty-free process. As shown in FIG. 6(B), a duty-free process suggestion image 630 indicating that the duty-free process is in progress is displayed. Thereby, the clerk can immediately grasp that the duty-free process is in progress.

[0048] Also, on the clerk display unit 21, a registered goods display area 631, an amount details area 632, and a total amount display area 633 are displayed. In the registered goods display area 631, the product name, unit price, purchase amount, and a notice of whether or not duty-free applies (indicating either the character "exempt" indicating that duty-free applies or a character indicating that duty-free does not apply (in the figure, the character "domestic")) of the goods registered in the current transaction are displayed in association.

[0049] In addition, in notifying whether tax exemption is applicable, the POS register 3 may display the applicable tax exemption category in addition to the character "exempt." For example, the POS register 3 may display characters or symbols indicating that a product registered in the tax exemption category of consumables is a consumable product, and may display characters or symbols indicating that a product registered in the tax exemption category of general goods is a general product. This allows the store clerk to know at a glance the tax exemption category of the registered product.

[0050] The amount detail area 632 displays the detailed amount and the total amount. The detailed amount displays the subtotal, taxable amount, total tax amount, total consumables amount, general goods tax exemption amount, and total tax exemption amount. The subtotal (¥29,500) is the total amount of each item eligible for tax exemption and the item not eligible for tax exemption (shoe sole repair). The taxable amount (¥1,852) is the amount excluding tax for the item not eligible for tax exemption (shoe sole repair). The total tax amount (¥148) is the taxable amount (¥1,852) for the item not eligible for tax exemption (shoe sole repair) multiplied by the consumption tax rate (e.g. 8%).

[0051] The total amount for consumables (¥3,500) is the sum of the price of the consumable item "XX beer" (¥500) and the price of the consumable item "XX lotion" (¥3,000). The general goods tax-free amount (¥24,000) is the sum of the price of the general item "XX shirt" (¥4,000) and the price of the general item "XX rice cooker" (¥20,000). The total tax-free amount (¥24,000) is the general goods tax-free amount.

[0052] If the total amount of consumables is the tax-free amount, the tax-free amount of consumables is displayed in the amount detail area 632. In this case, the total amount of tax-free items is the sum of the tax-free amount of general goods and the tax-free amount of consumables. The amount (¥29,500) displayed in the total amount display area 633 is the same as the subtotal (¥29,500).

[0053] As shown in Fig. 6(B), when the total amount of consumables does not reach 5,000 yen, pressing the subtotal button 613 will transition to the screen shown in Fig. 7(A). Note that when the total amount of consumables reaches 5,000 yen, pressing the subtotal button 613 will transition to a screen for settlement (not shown) without changing the tax-free category.

[0054] Fig. 7 is an explanatory diagram showing an example of the tax exemption selection screen when the subtotal button 613 is operated in the tax exemption process and at least one of the tax exemption categories of consumables and general goods is not the tax exemption applicable amount. Fig. 7(A) shows the tax exemption selection screen when the total amount of the products registered as consumables is not the tax exemption applicable amount and the total amount of the products registered as general goods is the tax exemption applicable amount. In Fig. 7(A), the clerk display unit 21 displays a notice that the total amount of the products registered as consumables is not the tax exemption applicable amount. The tax exemption applicable amount for consumables is 5,000 yen or more and 500,000 yen or less.

[0055] Additionally, a plurality of selection buttons 701 to 704 (an add product button 701, a tax exemption rejection button 702, a tax exemption approval button 703, and a tax exemption category change button 704) are displayed on the store clerk display unit 21. The add product button 701 is a button for adding and registering an additional product. When the add product button 701 is operated, the screen returns to, for example, the screen shown in FIG. 6(B).

[0056] The tax exemption refusal button 702 is a button for making a payment without applying for tax exemption. When the tax exemption refusal button 702 is operated, a payment screen (not shown) is displayed in which the tax exemption for the consumables is cancelled. In addition, on this payment screen, the total amount of the consumables (¥3,500) is also displayed with the consumption tax rate (¥280) taxed (¥3,780) and the total amount taking the taxed amount into consideration.

[0057] The tax exemption approval button 703 is a button for carrying out tax exemption. If the tax exemption condition is met, that is, the total amount of sales of consumables in one day at one store is 5,000 yen or more and 500,000 yen or less, the consumables are also eligible for tax exemption. Even if the total amount of consumables in the current transaction does not reach the tax exemption amount, if the tax exemption condition is met in a subsequent transaction, the consumables will be eligible for tax exemption, so it may be possible to carry out the tax exemption procedure for subsequent transactions, including the current transaction.

[0058] When the tax exemption approval button 703 is operated, if the total amount of the products registered as consumables does not reach the tax exemption amount, predetermined warning information is output. The predetermined warning information is output, for example, by displaying the difference between the total amount of the consumables and the tax exemption amount on the clerk display unit 21 or by printing it on the receipt. This allows the POS register 3 to notify the clerk and the customer of the difference between the total amount of the consumables and the tax exemption amount, and encourage the customer to purchase the difference. Note that if the total amount of the products registered as consumables exceeds 500,000 yen, the POS register 3 may be configured to notify the customer that tax exemption is not applicable to the consumables.

[0059] Even if the total amount of the products registered as consumables does not reach the tax-free amount, the tax-free conditions may be met by a subsequent transaction, so that the products may be exempt from tax and the payment may be processed by operating the tax-free approval button 703. Also, diplomats and those serving in the U.S. military (certain foreign nationals) may be exempt from tax by presenting a specific document to the store clerk. Therefore, even if the total amount of the products registered as consumables does not reach the tax-free amount, in transactions with certain foreign nationals, the products may be exempt from tax and the payment may be processed by operating the tax-free approval button 703.

[0060] The tax-free category change button 704 is a button for accepting a change of the tax-free category. When the tax-free category change button 704 is pressed, the screen shown in Fig. 8(A) appears, and it is possible to change the product registered in the tax-free category of general goods to the tax-free category of consumables. Note that, when the total amount of the products registered as consumables exceeds 500,000 yen, the POS register 3 cannot change the product registered as consumables to the tax-free category of general goods, so the tax-free category change button 704 may not be displayed.

[0061] Next, an example of another screen when the subtotal button 613 is operated in the tax exemption process will be described. Fig. 7(B) shows the tax exemption selection screen when the total amount of the products registered as consumables is not the tax exemption amount and there is no product registered as general goods. In Fig. 7(B), the tax exemption category change button 704 is not displayed. This is because there is no product registered as general goods, so the tax exemption category cannot be changed from general goods to consumables.

[0062] Fig. 7(C) shows the tax-free selection screen when the tax-free amount does not apply to either consumables or general goods. In Fig. 7(C), selection buttons 701 to 704 are displayed. For example, even if neither the total amount of consumables nor the total amount of general goods reaches the tax-free amount (5,000 yen), the total amount of the goods registered as consumables may reach the tax-free amount by changing some of the goods registered as general goods to the tax-free category of consumables. For this reason, tax-free category change button 704 is displayed to accept a change in the tax-free category from general goods to consumables.

[0063] Fig. 7(D) shows the tax-free selection screen when the total amount of general goods is not the tax-free applicable amount. In the screen of Fig. 7(D), for example, consumables do not have to be registered, and when consumables are registered, the total amount of consumables may be the tax-free applicable amount. In Fig. 7(D), selection buttons 701 to 704 are displayed.

[0064] Here, if the total amount of general goods sold in one store in one day meets the tax-free condition of 5,000 yen or more, the products registered as general goods are eligible for tax-free. Therefore, even if the total amount of general goods in this transaction does not reach the tax-free amount, if the tax-free condition is met in a subsequent transaction, the goods will be eligible for tax-free, so it is possible to carry out the tax-free procedure.

[0065] In Fig. 7(D), when the tax exemption approval button 703 is operated, the general goods are tax-exempt and the payment process is performed even if the total amount of the registered general goods does not reach the tax exemption amount. In this case, the difference between the total amount of the general goods and the tax exemption amount may be displayed on the clerk display unit 21 or printed on the receipt to encourage the customer to purchase up to the tax exemption amount.

[0066] 7(D), a tax-free category change button 704 is displayed. Even if the total amount of general goods does not reach the tax-free applicable amount, it is possible to change a product registered as a general good to the tax-free category of consumables and have it tax-free as a consumable. For this reason, the tax-free category change button 704 is displayed to accept a change in the tax-free category from general goods to consumables.

[0067] Fig. 8 is an explanatory diagram showing an example of a screen when accepting a change in the tax-free category. Fig. 8(A) shows a list display screen that accepts the selection of products for which the tax-free category is to be changed. In Fig. 8(A), each product eligible for tax-free listing shown in registered product display area 631 is displayed with either a "◆" mark indicating that it has been registered in the tax-free category for consumables, or a "●" mark indicating that it has been registered in the tax-free category for general goods.

[0068] In the registered product display area 631, there are two products registered as general goods: "XX shirt" and "XX rice cooker." For this reason, "XX shirt" and "XX rice cooker" can be selected as candidates for changing the tax-free category. Specifically, when the display area for "XX shirt" is pressed, the display mode of the display area for "XX shirt" changes, and it is selected as a candidate for changing the tax-free category. Similarly, when the display area for "XX rice cooker" is touched, the display mode of the display area for "XX rice cooker" changes, and it is selected as a candidate for changing the tax-free category.

[0069] It is also possible to select two products, "XX shirt" and "XX rice cooker", as candidates for changing the tax-free category. If the display area of ​​a product selected as a candidate for change is touched again, the selection as a candidate for change is cancelled.

[0070] On the other hand, even if the display areas of products registered as consumables ("XX beer" and "XX shirt") or the display areas of products not registered as tax-free items ("shoe sole repair") are pressed, the display state of these display areas does not change. In other words, these products are not selected as candidates for changing the tax-free category. This is because the "change of tax-free category" item in the product master (Fig. 4) is set to "not allowed." In particular, the POS register 3 prohibits the change of the category of products registered in the tax-free category of consumables to the tax-free category of general goods. Note that, when the display area of ​​a product registered as a consumable product or the display area of ​​a product not registered as tax-free item is pressed, the POS register 3 may notify the user that the category cannot be changed.

[0071] As shown in FIG. 8(A), when the decision button 801 is pressed in a state in which a general item "XX shirt" is selected, the screen transitions to a screen shown in FIG. 8(B).

[0072] Fig. 8(B) shows the screen after the tax-free category has been changed. In Fig. 8(B), a change notification 810 is displayed. The change notification 810 indicates that the tax-free category of the product "XX shirt" has been changed to consumables. Also, as shown in registered product display area 631 in Fig. 8(B), a notification image (●→◆) indicating that the tax-free category has been changed from general goods to consumables is displayed in the display area for "XX shirt".

[0073] In addition, since the total amount of the products registered as consumables is the tax-exempt amount, the tax-exempt amount for consumables (7,500 yen) is displayed in the amount detail area 632. The tax-exempt amount for consumables (7,500 yen) is the sum of the amount of the consumable "XX beer" (500 yen), the amount of the consumable "XX lotion" (3,000 yen), and the amount of the "XX shirt" that was changed from a general item to a consumable item (4,000 yen).

[0074] In addition, the general goods tax-free amount (20,000 yen) in the amount details area 632 is the amount (20,000 yen) of only the "XX rice cooker" excluding the amount (4,000 yen) of the "XX shirt" because the tax-free category of the "XX shirt" has been changed to consumables. The total tax-free amount (27,500 yen) in the amount details area 632 indicates the sum of the general goods tax-free amount and the consumables tax-free amount.

[0075] In addition, in Fig. 8(B), if "XX rice cooker" is selected in addition to "XX shirt" as a change target for the tax-free category, the "XX rice cooker" will also be changed to the tax-free category of consumables. When the settlement button 802 in Fig. 8(B) is operated, the settlement process starts with the contents shown in Fig. 8(B). When the settlement process is completed, the POS register 3 issues a receipt.

[0076] (Regarding receipts issued during tax exemption processing) Fig. 9 is an explanatory diagram showing an example of a receipt issued by the POS register 3 in the tax exemption process. The receipts issued in the tax exemption process include a customer receipt 900 received by the customer, a stick-on receipt 910 that is affixed to the box in which the consumables are packed, and a copy receipt that the store keeps. Fig. 9 explains the customer receipt 900 and the stick-on receipt 910. The copy for the store contains the same information as the customer receipt 900.

[0077] Fig. 9(A) shows a customer receipt 900 that a customer receives. In addition to the purchase date and time and receipt #, the details shown in Fig. 8(B), the amount deposited, and the change are printed on the customer receipt 900. Also, as shown on the customer receipt 900, for products registered in the tax-free consumables category, a "◆" mark indicating the tax-free consumables category is attached. Also, for products registered in the tax-free general goods category, a "●" mark indicating the tax-free general goods category is attached.

[0078] As shown in customer receipt 900, the "XX shirt" has a "●→◆" mark indicating that the tax-free category has been changed from general goods to consumables. Note that receipts received by customers in normal processing that does not involve tax-free processing do not have the "◆" or "●" mark.

[0079] FIG. 9(B) shows a stick-on receipt 910. The information printed on the customer receipt 900 is printed on the stick-on receipt 910, excluding the total amount, the deposit, and the change. The receipt # "00001" printed on the stick-on receipt 910 is the same number as on the customer receipt 900. Furthermore, on the stick-on receipt 910, consumables and general items are printed in different areas. By sticking such a stick-on receipt 910 on a packaging box, it becomes easier to identify the consumables stored in the packaging box during inspection at customs, etc.

[0080] In addition, since general items are not packaged, it is possible not to mention the general items on the stick-on receipt 910. Also, it is possible to make it selectable whether or not to mention the general items on the stick-on receipt 910. This selection may be made according to an operation by a store clerk performed each time a product is registered, or according to a setting by a store clerk during maintenance or the like.

[0081] Furthermore, if no general goods are listed on the stick-on receipt 910, the only products listed on the stick-on receipt 910 will be those registered in the tax-free consumables category. Therefore, if no general goods are listed on the stick-on receipt 910, there is no need to print the "consumables" item. Also, the "◆" mark indicating the tax-free consumables category does not need to be printed. However, even in this case, it is acceptable to print "●→◆" to indicate that the tax-free category has changed from general goods to consumables.

[0082] (An example of the process performed by the POS register 3) Next, an example of a process for displaying the screens shown in FIGS. 6 to 8 will be described with reference to FIGS.

[0083] (An example of the process for registering and paying for a product) 10 and 11 are flow charts showing an example of the process performed by the POS register 3 when registering an item and making a payment. In Fig. 10, the POS register 3 judges whether the item registration information has been scanned or the like (step S1001). Scanning or the like of the registration information specifically means inputting the registration information by touching the store clerk display unit 21, operating the key operation unit 22, scanning with the scanner unit 35, or the like.

[0084] If there is no scanning or the like (step S1001: NO), the POS register 3 judges whether or not tax exemption processing is in progress (step S1002). If tax exemption processing is in progress (step S1002: YES), the POS register 3 proceeds to step S1005. On the other hand, if tax exemption processing is not in progress (step S1002: NO), that is, if normal processing is in progress, the POS register 3 judges whether or not the tax exemption declaration button 611 (see FIG. 6) has been pressed (operated) (step S1003).

[0085] If the tax-exemption declaration button 611 is not pressed (step S1003: NO), the POS register 3 returns to step S1001. On the other hand, if the tax-exemption declaration button 611 is pressed (step S1003: YES), the POS register 3 changes from normal processing to tax-exempt processing (step S1004). Note that if the tax-exemption declaration button 611 is pressed during tax-exempt processing, the tax-exemption processing may be changed to normal processing.

[0086] Then, the POS register 3 judges whether or not the tax-free category change button 612 has been pressed (step S1005). If the tax-free category change button 612 has not been pressed (step S1005: NO), the POS register 3 returns to step S1001. On the other hand, if the tax-free category change button 612 has been pressed (step S1005: YES), the POS register 3 executes a tax-free category change reception process that displays a screen for receiving a change in the tax-free category shown in Fig. 8 (step S1006), and returns to step S1001. Details of the tax-free category change reception process will be described later with reference to Fig. 13.

[0087] In step S1001, if scanning, etc. has been performed (step S1001: YES), the POS register 3 calculates the amount (total amount) of the scanned product multiplied by the consumption tax rate (step S1007A). Furthermore, the POS register 3 calculates the amount (total amount) of the scanned product not multiplied by the consumption tax rate (step S1007B). Note that either the process of step S1007A or step S1007B may be performed first. In other words, the POS register 3 calculates the amount multiplied by the consumption tax rate and the amount not multiplied by the consumption tax rate for the scanned product, regardless of whether tax-free processing is being performed or not. Then, the POS register 3 determines whether tax-free processing is being performed or not (step S1008). If the tax exemption process is not in progress (step S1008: NO), that is, if normal processing is in progress, the POS register 3 displays that normal processing is in progress (for example, displays the screen in FIG. 6(A)) (step S1009), and proceeds to step S1012. Note that the amount multiplied by the consumption tax rate is displayed on the display screen during normal processing.

[0088] On the other hand, if tax exemption processing is in progress (step S1008: YES), the POS register 3 calculates the amount for each tax exemption category (step S1010). The amount for each tax exemption category is, specifically, the amount for each consumable item or each general item. The POS register 3 then displays that tax exemption processing is in progress (for example, displays the screen in FIG. 6(B)) (step S1011). Note that the display screen during tax exemption processing shows either the amount multiplied by the consumption tax rate or the amount not multiplied by the consumption tax rate, depending on whether or not the item is subject to tax exemption.

[0089] Next, the POS register 3 judges whether or not the subtotal key or the subtotal button 613 (see FIG. 6) of the key operation unit 22 has been pressed (step S1012). If the subtotal key or the like has not been pressed (step S1012: NO), the POS register 3 returns to step S1001. On the other hand, if the subtotal key or the like has been pressed (step S1012: YES), the POS register 3 judges whether or not the tax exemption process is in progress (step S1013).

[0090] If the tax exemption process is not in progress (step S1013: NO), the POS register 3 proceeds to step S1021. On the other hand, if the tax exemption process is in progress (step S1013: YES), the POS register 3 determines whether or not the amount of at least one of the total amount of the products registered in the tax exemption category of consumables and the total amount of the products registered in the tax exemption category of general goods is an amount not subject to tax exemption (step S1014).

[0091] If the amount of at least one of the categories is not the tax-exempt amount (step S1014: NO), i.e., if the amounts of both tax-exempt categories are within the tax-exempt amount, if the amount of the tax-exempt category for consumables is within the tax-exempt amount and no general goods are registered, the POS register 3 proceeds to step S1021.

[0092] If at least one of the total amount of the products registered in the tax-free category of consumables and the total amount of the products registered in the tax-free category of general goods is not tax-exempt (step S1014: YES), the POS register 3 performs a tax-exemption selection screen display process to display a different tax-exemption selection screen (see Fig. 7(A)-(D)) according to the tax-exemption category that does not reach the tax-exemption amount (step S1015). Details of the tax-exemption selection screen display process will be described later with reference to Fig. 12.

[0093] The POS register 3 then judges whether or not the tax-free category change button 704 has been pressed on the tax-free selection screen (for example, FIG. 7(A)) (step S1016). If the tax-free category change button 704 has been pressed (step S1016: YES), the POS register 3 executes a tax-free category change acceptance process (see FIG. 13) that accepts the change of the tax-free category (step S1017). Then, when the change of the tax-free category is completed, the POS register 3 judges whether or not the settlement button 802 (see FIG. 8) has been pressed (step S1018).

[0094] The POS register 3 waits until the settlement button 802 is pressed (step S1018), and when the settlement button 802 is pressed (step S1018: YES), the process proceeds to step S1021. If the tax-free category change button 704 is not pressed in step S1016 (step S1016: NO), the POS register 3 judges whether the product addition button 701 is pressed (step S1019). If the product addition button 701 is pressed (step S1019: YES), the POS register 3 returns to step S1001.

[0095] On the other hand, if the product addition button 701 is not pressed (step S1019: NO), the POS register 3 judges whether the tax exemption refusal button 702 or the tax exemption acceptance button 703 is pressed (step S1020). If the tax exemption refusal button 702 or the tax exemption acceptance button 703 is not pressed (step S1020: NO), the POS register 3 returns to step S1016.

[0096] If the tax exemption refusal button 702 or the tax exemption acceptance button 703 is pressed (step S1020: YES), the POS register 3 starts the settlement process (step S1021). Here, a supplementary explanation of the settlement process will be given. If the tax exemption refusal button 702 or the tax exemption acceptance button 703 is pressed in step S1020, the settlement process is carried out according to the accepted operation. If a tax exemption category change acceptance process is carried out, the settlement process is carried out according to the tax exemption category accepted in that process. If normal processing is being carried out, the normal settlement process is carried out without tax exemption.

[0097] In addition, in the settlement process, the amount received from the customer is input and the input amount is displayed. Then, the POS register 3 judges whether or not an end button such as a current total key has been pressed (step S1022). The POS register 3 waits until the end button is pressed (step S1022: NO), and when the end button is pressed (step S1022: YES), it judges whether or not the tax exemption process is in progress (step S1023).

[0098] If the tax-free process is not in progress (step S1023: NO), the POS register 3 outputs a normal receipt issued in normal processing (step S1024) and ends the series of processes. On the other hand, if the tax-free process is in progress (step S1023: YES), the POS register 3 outputs a tax-free receipt issued in the tax-free process (step S1025). Then, the POS register 3 determines whether or not there is a product registered as a consumable item (step S1026).

[0099] If there are no products registered as consumables (step S1026: NO), that is, if all registered products are registered as general goods, the POS register 3 proceeds to step S1028. On the other hand, if there are products registered as consumables (step S1026: YES), the POS register 3 displays a packing guidance screen (not shown) for packing the consumables (step S1027).

[0100] Here, we will provide additional guidance on packaging. When packaging consumables, transparent plastic bags that allow the contents to be identified, cardboard boxes with written notices describing the contents attached, etc. are used. For sealing, a sticker is used that allows identification of the opening if the box is opened before departure. Also, a notice calling for the passenger not to open the bag or box until departure and a list of the items and quantities of the products to be packaged (for example, a receipt to be attached 910) are attached to the bag or box.

[0101] A new employee or other store clerk who is unfamiliar with the tax-free procedures may not understand this packing procedure. Even a store clerk who is familiar with the tax-free procedures may skip the steps when packing items. For this reason, the POS register 3 displays a packing guidance screen that shows the steps of the packing procedure. This allows the store clerk to perform the packing procedure simply and easily. In this flowchart, the packing guidance screen is displayed only when there is a product registered as a consumable item.

[0102] After displaying the packing guidance screen, the POS register 3 transmits purchase record information, including information on the tax-free products and the purchase amount, to the store controller 2 (step S1028), and ends the series of processes.

[0103] The store controller 2 transmits the purchase record information received from the POS register 3 to a computer device of a predetermined institution (e.g., the National Tax Agency). However, the purchase record information is not limited to being transmitted from the store controller 2 to the computer device, but may be transmitted directly from the POS register 3 to the computer device.

[0104] (An example of tax exemption selection screen display processing) Next, the tax-exemption selection screen display process shown in step S1015 of Fig. 11 will be described. Fig. 12 is a flow chart showing an example of the tax-exemption selection screen display process performed by the POS register 3. In Fig. 12, the POS register 3 judges whether the amounts in the tax-exempt categories for both consumables and general goods are not subject to tax exemption (step S1201). If the amounts in both tax-exempt categories are not subject to tax exemption (step S1201: YES), the POS register 3 displays a tax-exemption selection screen (see Fig. 7(C)) indicating that the amounts in both tax-exempt categories are not subject to tax exemption, and ends the series of processes.

[0105] If the amounts in both tax-free categories are not the tax-exempt amount (step S1201: NO), i.e., if at least one of the tax-exempt categories is the tax-exempt amount, the POS register 3 judges whether the amount of the consumables is the tax-exempt amount (step S1203). If the amount of the consumables is not the tax-exempt amount (step S1203: NO), i.e., if the amount of the general goods is the tax-exempt amount, the POS register 3 displays a tax-exempt selection screen (see FIG. 7(D)) indicating that the amount of the general goods is the tax-exempt amount (step S1204), and ends the series of processes.

[0106] On the other hand, if the amount of consumables is less than the tax-free application amount (step S1203: YES), the POS register 3 judges whether the registered products are only consumables (step S1205). If the registered products are not only consumables (step S1205: NO), that is, if general goods are also registered, a tax-free selection screen (with tax-free category change button 704 in FIG. 7(A)) indicating that the amount of consumables does not reach the tax-free application amount is displayed (step S1206), and the series of processes is terminated.

[0107] On the other hand, if the only products being registered are consumables (step S1205: NO), that is, if no general goods are registered, a tax-free selection screen (without the tax-free category change button 704 in FIG. 7(B)) indicating that the amount of consumables does not reach the tax-free applicable amount is displayed (step S1207), and the process ends.

[0108] (An example of tax-free classification change acceptance processing) Next, a description will be given of the tax-free category change acceptance process shown in step S1006 in Fig. 10 and step S1017 in Fig. 11. Fig. 13 is a flowchart showing an example of the tax-free category change acceptance process performed by the POS register 3. In Fig. 13, the POS register 3 determines whether or not there is a product eligible for tax exemption (step S1301).

[0109] If there are no products eligible for tax exemption (step S1301: NO), the POS register 3 proceeds to step S1304. On the other hand, if there are products eligible for tax exemption (step S1301: YES), the POS register 3 extracts the products eligible for tax exemption (step S1302). Then, the POS register 3 determines whether the tax exemption category of the registered product is consumables only (step S1303).

[0110] If the tax-free category of the product being registered is consumables only (step S1303: YES), that is, if no general goods are registered, the POS register 3 displays an error message indicating that the tax-free category cannot be changed (step S1304), and ends the process.

[0111] The error message may be a screen with different contents depending on whether there is no product eligible for tax exemption (step S1301: NO) or whether the product being registered is classified as only consumables (step S1303: NO). Specifically, the error message may be a screen indicating that the product eligible for tax exemption itself is not registered, or a screen indicating that only consumables are registered.

[0112] In step S1303, if the tax-free category of the registered product is not only consumables (step S1303: NO), that is, if general goods are also registered, the POS register 3 displays a tax-free category change acceptance screen (see FIG. 8(A)) (step S1305).Then, the POS register 3 judges whether or not the selection of the product to be changed in tax-free category from general goods to consumables has been accepted (step S1306).

[0113] The POS register 3 waits until it receives the selection of the product for which the tax-free category is to be changed (step S1306: NO), and upon receiving the selection (step S1306: YES), it changes the tax-free category of the selected product from general goods to consumables (step S1307), and ends the series of processes.

[0114] (Functional configuration of POS register 3) Next, a description will be given of the functional configuration of the POS register 3. The POS register 3 includes a registration unit, a classification change receiving unit, a classification change processing unit, and a receipt output unit.

[0115] The registration unit registers products. Specifically, the registration unit registers transaction information (see FIG. 5) for each product, including the tax-free category. The tax-free category is, for example, the tax-free category of "consumables" and "general goods."

[0116] The category change reception unit accepts changes to the tax-free category of products registered in the registration unit. The category change reception unit accepts changes to the tax-free category by touching the clerk display unit 21, operating the key operation unit 22, etc. The timing for accepting changes to the tax-free category may be any timing, such as before, during, or after the product is registered. The category change reception unit accepts changes to the tax-free category by pressing the tax-free category change button 612 (see FIG. 6).

[0117] When a change to the tax-free category is accepted by the category change acceptance unit, the category change processing unit changes the tax-free category of the product registered in the registration unit to the accepted tax-free category. The category change processing unit enables a change of the tax-free category from the general goods tax-free category to the consumable goods tax-free category. On the other hand, the category change processing unit prohibits a change of the tax-free category from the consumable goods tax-free category to the general goods tax-free category. Note that the category change processing unit may enable a change of the tax-free category from the consumable goods tax-free category to the general goods tax-free category.

[0118] (Display when accepting changes to tax-free classification) The category change acceptance unit accepts a change in the tax-free category by displaying on the display unit those products for which the tax-free category can be changed among the products registered in the registration unit. Products for which the tax-free category can be changed are general goods. The category change acceptance unit is only required to display on the display unit at least those products registered as general goods, i.e., it may not display on the display unit those products registered as consumables. Preventing products registered as consumables from being displayed on the display unit will be described in a modified example below.

[0119] The classification change reception unit also displays a list of the products registered in the registration unit and their tax-free classifications on the display unit (see FIG. 8(A)), and accepts changes to the tax-free classification. The classification change reception unit also accepts the selection of the product to be changed from the list, and the selection of the new tax-free classification.

[0120] The display unit is, for example, a store clerk display unit 21. In the case where a customer registers a product, such as in a self-checkout, the display unit may be a customer display unit 23.

[0121] Furthermore, when the classification change processing unit changes the tax-free classification of a product registered in the registration unit, it causes the display unit to display a notification image indicating that the tax-free classification of the product has been changed. The notification image may be a text notification image (change notification 810 in FIG. 8(B)) or a mark notification image ("●→◆" in FIG. 8(B)). Note that the POS register 3 may use the audio output unit 37 to give an audio notification when displaying that the tax-free classification of the product has been changed.

[0122] (Printing on print media) The receipt output unit prints receipts for the products registered in the registration unit, separated by tax-free category. The receipt is, for example, a paper receipt. However, the receipt is not limited to a paper receipt, and may be an electronic receipt or an electronic journal. The electronic receipt or electronic journal may be displayed on the customer display unit 23, or may be output to a mobile terminal held by the customer via communication or imaging. In this embodiment, receipts include a customer receipt 900 (including a copy for the store) and a stick-on receipt 910, as shown in FIG. 9. The receipt output unit may print at least the stick-on receipt 910 separated by tax-free category.

[0123] Here, printing separately for each tax-free category may mean printing on one print medium in separate areas for each tax-free category, or printing on different print media for each tax-free category. When printing on different print media for each tax-free category, it is sufficient to attach the print media on which only the products registered as consumables are printed to the packing box. This makes it easier for staff at customs and the like to know which consumables are stored in the packing box.

[0124] It should be noted that the customer receipt 900 does not have to print products according to their tax-free category. Specifically, the customer receipt 900 may register products in the order in which they were registered, i.e., the products may be printed in a mixed tax-free category. In this case, products registered in the tax-free category of consumables may be printed in a different display format from other products. The different display format may be a display format of a different size, a different color, a different font, or the like.

[0125] The receipt output unit also outputs, in an identifiable manner, that the tax-free category of the product for which the category change acceptance unit has accepted a change has been changed. Specifically, the receipt output unit also prints, on the print medium, a notification image (an image of "●→◆") indicating that the tax-free category of the product displayed on the display unit has been changed. The printing unit only needs to print, on at least the stick-on receipt 910 out of the customer receipt 900 and the stick-on receipt 910, that the tax-free category of the product has been changed.

[0126] The above-mentioned registration unit, category change reception unit, category change processing unit, and receipt output unit are realized by the CPU 41. Specifically, the CPU 41 executes a product sales data processing program stored in the RAM 43 or the like to realize the functions of each unit.

[0127] As described above, the POS register 3 of this embodiment can accept a change in the tax-free category and change the tax-free category of a registered product to the accepted tax-free category. This allows a store clerk or customer to register a product in the tax-free category they desire. This allows flexible tax-free processing.

[0128] In addition, the POS register 3 of this embodiment displays on the display unit those registered products for which the tax-free category can be changed, and accepts changes to the tax-free category. This allows the store clerk to easily know which products have a tax-free category that can be changed, and therefore makes it easy to change the tax-free category. Therefore, the POS register 3 of this embodiment can favorably support the store clerk's operation to change the tax-free category.

[0129] In addition, the POS register 3 of this embodiment displays a list of registered products and their tax-free categories on the display unit, and accepts changes to the tax-free category. This allows the store clerk to know the tax-free category of each product at a glance, making it easy to change the tax-free category.

[0130] In addition, the POS register 3 of this embodiment allows the tax-free classification of a product registered as a general product to be changed to a tax-free classification of consumables, but prohibits the tax-free classification of a product registered as a consumable product from being changed to a tax-free classification of general products. This makes it possible to prevent a registered product from being changed to a tax-free classification that is not eligible for tax exemption. Therefore, it is possible to support the appropriate change of tax-free classification.

[0131] In addition, the POS register 3 of this embodiment is configured to display a notification image indicating that the tax-free category of the registered product has been changed on the store clerk display unit 21 when the tax-free category of the registered product is changed. This allows the store clerk to easily understand the new tax-free category. This makes it possible to support the store clerk in changing the tax-free category appropriately.

[0132] In addition, the POS register 3 of this embodiment outputs the change in tax-free category of the product for which the change in tax-free category has been accepted in a identifiable manner. Therefore, the staff of the customs office and customers can easily know the product for which the tax-free category has been changed.

[0133] In addition, the POS register 3 of this embodiment prints registered products on paper media (stick-on receipts 910) by classifying them according to tax-free classification. By sticking such stick-on receipts 910 on a packing box, it becomes easier to identify the consumables stored in the packing box during inspection by customs, etc.

[0134] (Modification of the embodiment) Next, modified examples of the embodiment will be described. Note that in the following modified examples, the contents described in the above embodiment will not be described as necessary.

[0135] (First Modification of the Embodiment) First, a first modified example of the embodiment will be described. In the above-described embodiment, a configuration in which consumables and general goods are displayed on the screen for accepting changes to the tax-free category (see FIG. 8(A)) has been described. In the first modified example, in addition to or instead of such a configuration, a configuration in which only general goods are displayed on the screen for accepting changes to the tax-free category will be described.

[0136] Fig. 14 is an explanatory diagram showing a modified example of the screen when accepting a change of the tax-free category. As shown in Fig. 14, only general goods that are the subject of the change of the tax-free category are displayed on the store clerk display unit 21. In other words, unlike the list display screen shown in Fig. 8(A), consumables are not displayed.

[0137] In Fig. 14, when the area of ​​a displayed product is pressed, the product is selected as a candidate for changing the tax-free category. In addition, a Bulk Change button 1401 and a Confirm button 1402 are displayed on the store clerk display unit 21. When the Bulk Change button 1401 is pressed, all displayed products are selected as candidates for changing the tax-free category. In addition, when the Confirm button 1402 is pressed, the tax-free category of the candidate products is changed.

[0138] As described above, in the first modification, the POS register 3 displays on the display unit only those products among the registered products whose tax-free category can be changed, and accepts changes to the tax-free category. This allows the POS register 3 to support easy and quick selection of change candidates. Furthermore, the POS register 3 can prevent incorrect changes to the tax-free category, and therefore supports appropriate changes to the tax-free category.

[0139] (Modification 2 of the embodiment) Next, a second modified example of the embodiment will be described. In the above-mentioned embodiment, a configuration (see FIG. 8) has been described in which a change to the tax-free category is accepted from a store clerk and the tax-free category is changed. In the second modified example, in addition to or instead of the above configuration, a configuration will be described in which a change candidate product is identified from products registered as general goods without accepting a change to the tax-free category from a store clerk, and the tax-free category of the identified change candidate product is automatically changed.

[0140] Fig. 15 is an explanatory diagram showing an example of a screen when the tax-free category is automatically changed. Fig. 15(A) is the same screen as Fig. 7(A). When the tax-free category change button 704 is pressed in Fig. 15(A), the screen transitions to the screen shown in Fig. 15(B). Fig. 15(B) shows the screen after the tax-free category has been automatically changed.

[0141] Here, an example of the process performed by the POS register 3 to display the screen shown in Fig. 15(B) will be described. For example, the POS register 3 changes the lowest priced general goods to the tax-free consumable goods category to prevent the total amount of the goods registered as general goods from falling short of the tax-free amount.

[0142] Here, we will explain how to specify a low-priced product as a product that is subject to a change in tax-free category. For example, if the total price of the products currently registered as consumables is ¥3,500, the POS register 3 calculates the shortfall (¥1,500) until the tax-free amount (¥5,000) is reached. Then, the POS register 3 calculates the difference between the price of each product registered as a general item and the shortfall.

[0143] For example, the difference between the price of "XX shirt" (4,000 yen) and the shortfall (1,500 yen) is 2,500 yen. Also, the difference between the price of "XX rice cooker" (20,000 yen) and the shortfall (1,500 yen) is 18,500 yen. Furthermore, the POS register 3 identifies the product with the smallest difference that is equal to or greater than the shortfall (1,500 yen).

[0144] Specifically, the difference in price for the "XX shirt" (2,500 yen) is greater than or equal to the shortfall (1,500 yen) and is smaller than the difference in price for the "XX rice cooker" (18,500 yen). Therefore, the POS register 3 identifies the "XX shirt", which is registered as a general item, as a candidate for change. The POS register 3 then changes the tax-free category of the identified "XX shirt" to a consumable item.

[0145] Also, the registered product display area 631 in FIG. 15(B) shows that the tax-free category of "XX shirt" has been changed to consumables. Also, each amount displayed in the amount detail area 632 shows the amount after the tax-free category has been changed. Also, the change notice 1510 shows that the tax-free category has been automatically changed and that the changed tax-free category can be canceled. Also, a cancel button 1501 is displayed on the store clerk display unit 21. When the cancel button 1501 is touched, the POS register 3 cancels the change of the tax-free category and accepts the selection of a change candidate by the store clerk as shown in FIG. 8(A).

[0146] If the total price of the general goods registered as general goods falls below the tax-free amount by changing the tax-free category of the candidate product, the user may be notified of the change. In this case, the POS register 3 may not automatically change the tax-free category of the candidate product, but may accept an operation by a store clerk and change the tax-free category of the candidate product according to the result of the operation.

[0147] As described above, in the second modification, the POS register 3 identifies candidates for change from among the registered general goods based on the total price (¥3,500) of the goods registered as consumables, the prices of each product registered as general goods (XX shirt and XX rice cooker), and the tax-free applicable amount (¥5,000). The POS register 3 then changes the identified candidate goods to the tax-free category of consumables. This allows the POS register 3 to reduce the number of operations required by the store clerk when changing the tax-free category, and therefore supports quick changes to the tax-free category.

[0148] In addition, in the second modification, a low-priced item is specified as a general item that is subject to a change in the tax-free category. Therefore, even if an item registered as a general item is changed to a tax-free category of consumables, the POS register 3 can prevent the total price of the items registered as general items from falling below the tax-free applicable amount for general items. The POS register 3 can also prevent the total price of the items registered as consumables from exceeding 500,000 yen. Therefore, the POS register 3 can appropriately change the tax-free category.

[0149] The tax-free category may be automatically changed according to settings. Specifically, the function for automatically changing the tax-free category may be set to ON / OFF in a setting change mode in which the settings of various functions of the POS register 3 are changed. When the automatic change function is OFF, the screen may transition to a screen for accepting changes to the tax-free category (see FIG. 8(A)) after the tax-free category change button 704 (see FIG. 7) in FIG. 15(A) is pressed. With this configuration, the POS register 3 can automatically change the tax-free category according to settings.

[0150] The tax-free category may be automatically changed according to the settings of each store clerk. Specifically, the POS register 3 may store the store clerk identification information in association with the ON / OFF setting information of the automatic change function. This allows the POS register 3 to turn the automatic change function ON / OFF after each store clerk. With this configuration, the POS register 3 can automatically change the tax-free category according to the settings of each store clerk.

[0151] Furthermore, before the tax-free category is automatically changed (for example, after the tax-free category change button 704 is pressed in FIG. 15(A)), a selection as to whether or not to automatically change the tax-free category may be accepted. Then, the POS register 3 may perform the automatic change when a selection to perform the automatic change is accepted. With this configuration, the POS register 3 can change the tax-free category according to the clerk's selection, without automatically changing the tax-free category, in cases where the clerk has decided for himself the product for which the tax-free category will be changed.

[0152] In this embodiment, even if the product registered as a general item does not reach the tax exemption amount, the tax exemption category can be changed. Specifically, as shown in Fig. 7(C) and (D), even if the product registered as a general item does not reach the tax exemption amount, the tax exemption category change button 704 is displayed so that it can be pressed. In this way, even if the product registered as a general item does not reach the tax exemption amount, an automatic change may be performed.

[0153] (Modification 3 of the embodiment) Next, a third modification of the embodiment will be described. In the second modification described above, a configuration in which all steps up to changing the tax-free category are performed automatically is described. In the third modification, in addition to or instead of such a configuration, a configuration in which a store clerk makes the final decision on the change when changing the tax-free category of a change candidate is described. That is, in the third modification, a configuration in which a change candidate product is identified from products registered as general goods, and a change to the tax-free category of the identified change candidate product is accepted is described.

[0154] 15(A), for example, when the tax-free category change button 704 is pressed, the POS register 3 identifies a candidate for changing the tax-free category (e.g., "XX shirt") using the calculation results of the total price of consumables, the difference, the shortfall, etc., as explained in Modification Example 3. Then, the POS register 3 displays the identified candidate product and allows the clerk to change the tax-free category of the product.

[0155] With this configuration, the POS register 3 can identify and automatically display candidates for tax-free categories without receiving an operation from a store clerk to select a candidate for change.The POS register 3 can change the tax-free category by simply receiving a request from the store clerk to change the tax-free category of the candidate product.The POS register 3 can therefore reduce the number of operations by the store clerk when changing the tax-free category, and can quickly change the tax-free category.

[0156] (Fourth Modification of the Embodiment) Next, a fourth modified example of the embodiment will be described. In the above-described embodiment, a configuration for displaying the product name and price of a general product when changing the tax-free category (see FIG. 8(A) and FIG. 14) has been described. In the fourth modified example, in addition to or instead of such a configuration, a configuration for displaying the suitability of packaging for a product registered as a general product will be described.

[0157] In the fourth modification, the product master (see FIG. 4) may store attribute information relating to dimensions for products whose tax-free category is general goods in association with the product. The attribute information is, for example, packing suitability information indicating whether or not the product is suitable for packing. The attribute information may also be information on the dimensions themselves. Products that are suitable for packing are products whose dimensions fit into a packing box, and more specifically, products that are smaller than a certain dimension. In this case, the product master may store packing suitability information indicating that the product is suitable for packing in association with the product.

[0158] On the other hand, a product that is unsuitable for packaging is a product that is larger than a certain dimension. For example, a product that is unsuitable for packaging is a large product such as a television or furniture. In this case, the product master may store packaging suitability information indicating that packaging is unsuitable in association with the large product.

[0159] The POS register 3 displays information regarding dimensions when accepting a change in the tax-free category. Specifically, for a product associated with packaging suitability information indicating that packaging is unsuitable, the POS register 3 displays a message indicating that the product is not suitable for packaging. For example, the POS register 3 may display characters or a mark indicating "large size" in the display area of ​​the product.

[0160] Furthermore, the POS register 3 displays, on the screen for accepting changes to the tax-free category, products associated with packing suitability information indicating that the products are suitable for packing, while the POS register 3 may not display products associated with packing suitability information indicating that the products are not suitable for packing.

[0161] The packing suitability information may also include information indicating a priority according to the dimensions of the product. For example, the smaller the size of the product, the higher the priority. The POS register 3 may also display products with higher priority at the top of the screen that accepts changes to the tax-free category.

[0162] In the fourth modification, the POS register 3 accepts a change in the tax-free category of a registered general item based on attribute information associated with the item. Therefore, the POS register 3 can change the category of a general item that is suitable for packaging to a tax-free consumable item. Therefore, the POS register 3 can support an appropriate tax-free procedure.
