Abstract

To provide an article sale data processing apparatus and program capable of simplifying an article registration operation for an object article of a reduced tax rate.SOLUTION: A default tax rate setting part (initial setting means) sets, at a start of a transaction of a specific article, a tax rate associated with the transaction to one of a first tax rate corresponding to a first purchase style and a second tax rate corresponding to a second purchase style and unequivocally related to the first tax rate. Until a tax rate change setting part (setting change means) makes change from the setting of the first tax rate or second tax rate to change to the second tax rate or first tax rate, a tax amount calculation part (tax amount calculation means) calculates a tax amount of the specific article based upon the tax rate before the setting change. Further, until a tax rate change setting cancel part (setting change cancel means) puts the setting of the tax rate back to the setting before the change, the tax amount calculation part calculates a tax amount of the specific article based upon the tax rate before setting change cancel. Then a display control part (display means) displays the tax rate being set on a monitor for clerk and a monitor for customer.SELECTED DRAWING: Figure 5

Description

Embodiments of the present invention relate to product sales data processing devices and programs.

At stores where purchased products (food and beverages) can be eaten in the store, the consumption tax amount is set lower than when eating and drinking in the store (eat-in) when taking home the product (takeout) as part of the reduced tax rate system. The law is scheduled to come into effect.

In a sales data processing device that registers and setstles a product purchased by a customer, a product registration method corresponding to the case where such a reduced tax rate is enforced has been proposed (for example, Patent Document 1).

However, the proposed sales data processing device is troublesome because it takes time and effort to register each item in order to confirm whether the item is subject to the reduced tax rate.

An object to be solved by the present invention is to provide a product sales data processing device and a program capable of simplifying a product registration operation of a product subject to a reduced tax rate.

The product information registration device of the embodiment includes an initial setting means, a setting changing means, a setting change canceling means, a display means, and a tax amount calculating means. At the start of the transaction, the initial setting means uniquely associates the tax rate related to the transaction of the specific product with the first tax rate corresponding to the first purchase format or the first tax rate corresponding to the second purchase format. Set to one of the second tax rates given. The setting changing means changes the setting of the tax rate of the specific product from the setting of the first tax rate or the second tax rate set by the initial setting means to the setting of the second tax rate or the first tax rate. The setting change canceling means cancels the tax rate setting changed by the setting changing means and returns to the setting before the change. The display means displays the set tax rate. The tax amount calculation means is used before the setting change until the tax rate setting change is made by the setting change means or until the tax rate setting change is canceled by the setting change cancellation means during one transaction. Alternatively, the tax amount of the specific product is calculated based on the tax rate set before the cancellation of the setting change.

Hereinafter, the POS terminal according to the present embodiment will be described with reference to the attached drawings. In particular, when the POS terminal of the present embodiment registers the product information of the product purchased by the customer, whether or not the product is purchased corresponding to the reduced tax rate, for example, the product is registered in the eat-in format or the product is registered in the take-out format. It efficiently selects whether to register the product. The POS terminal is an example of a product sales data processing device. Further, the embodiment described below is an embodiment of the product sales data processing device and the program, and does not limit the configuration, specifications, and the like.

(Explanation of the outline configuration of the POS terminal)
FIG. 1 is an external perspective view of the POS terminal according to the embodiment. The POS terminal 2 is installed in a store such as a supermarket, and performs a registration process for registering product information of a product purchased by a customer and a payment process for the product registered by the registration process by the operation of a clerk.

The POS terminal 2 includes a drawer 12, a keyboard 13, a store clerk monitor 14, a customer monitor 16, a receipt printer 17, and a barcode reader 19.
The keyboard 13 and the clerk monitor 14, which are user interfaces, are arranged on the upper surface of the POS terminal 2, with the keyboard 13 on the front side and the clerk monitor 14 on the back side.

The drawer 12 is provided with a drawer for storing cash and the like. The POS terminal 2 controls the opening / closing operation of the drawer.

The keyboard 13 includes a plurality of keys such as a number key, a clear key, a return key, a subtotal key, and a deposit / current total key. The numeric keypad is a numeric keypad for inputting numerical values such as a product code and an amount. The clear key is a key for canceling an operation when an error occurs. The return key is a key for canceling the current operation and returning to the previous screen. The subtotal key is a key for completing sales registration and declaring the calculation of the total sales amount. The deposit / current total key is a key for calculating the change amount by pressing the deposit amount after inputting the amount deposited from the customer. When the deposit / current account key is pressed, the POS terminal 2 opens the drawer of the drawer 12, and the clerk stores the banknotes and coins given by the customer in the drawer 12 and changes from the drawer 12. Take out and give it to the customer.

The store clerk monitor 14 is composed of a display device such as an LCD (Liquid Crystal Display). The clerk monitor 14 displays a screen corresponding to a processing state such as registration processing and payment processing on the cashier operating the POS terminal 2.

A touch panel 15 is laminated on the surface of the display device constituting the store clerk monitor 14. The touch panel 15 detects the pressing of the cashier on the screen or button displayed on the store clerk monitor 14, and controls the operation of the POS terminal 2 according to the pressed position. The cashier performs necessary input operations using either the keyboard 13 or the touch panel 15.

The receipt printer 17 is arranged on the left side of the upper surface of the POS terminal 2 and prints a statement slip and a receipt (receipt) handed to the customer. Further, the receipt printer 17 is provided with an issuing port 18 to issue a printed statement slip and a receipt. The receipt printer 17 feeds the roll paper installed inside in the direction of feeding from the issuing port 18 by transporting the roll paper installed by a roller rotationally driven by a pulse motor (not shown) or the like. At this time, the receipt printer 17 prints the statement slip and the receipt on the roll paper by, for example, a thermal head (not shown). The detailed information, which is the data to be printed on the detailed slip, and the receipt information, which is the data to be printed on the receipt, are generated by the CPU 31a (see FIG. 2) described later and transmitted to the receipt printer 17.

The customer monitor 16 is composed of a display device such as an LCD, and is provided on the back side of the upper surface of the POS terminal 2. The customer monitor 16 is arranged with the display surface facing the customer, and displays the amount of the registered product, the total amount, and the like.

Further, the POS terminal 2 is connected to a bar code reader 19 that reads the product code held by the bar code from the bar code attached to the product. The bar code reader 19 decodes (decodes) the received signal of the product code, acquires the product code expressed by the bar code, and outputs the product code to the CPU 31a (see FIG. 2) of the POS terminal 2.

(Explanation of hardware configuration of POS terminal)
Next, the hardware configuration of the POS terminal 2 will be described with reference to FIG. FIG. 2 is a hardware block diagram showing an example of the hardware configuration of the POS terminal. As shown in FIG. 2, the POS terminal 2 includes a control unit 31, a storage unit 32, an I / O device control unit 34, and a communication I / F 35.

The control unit 31 controls the entire POS terminal 2. The control unit 31 has a general computer configuration including a CPU (Central Processing Unit) 31a, a ROM (Read Only Memory) 31b, and a RAM (Random Access Memory) 31c. The CPU 31a expands various programs stored in the ROM 31b and the storage unit 32 into the RAM 31c. The CPU 31a operates according to various programs developed in the RAM 31c, and controls the entire POS terminal 2.

The control unit 31 connects the storage unit 32, the I / O device control unit 34, and the communication I / F 35 via the bus line 33.

The storage unit 32 is a non-volatile memory typified by an HDD (Hard Disk Drive) or a flash memory in which stored information is held even when the power is turned off. The storage unit 32 stores a program or the like including the control program P1. The control program P1 is a program for exerting the functions provided in the POS terminal 2.

The control program P1 may be provided by being incorporated in the ROM 31b in advance. Further, the control program P1 is a file in a format that can be installed in the control unit 31 or in an executable format, and is recorded on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD. It may be configured to provide. Further, the control program P1 may be stored on a computer connected to a network such as the Internet and provided by downloading via the network. Further, the control program P1 may be configured to be provided or distributed via a network such as the Internet.

Further, the storage unit 32 stores the product master M1, the tax rate master M2, the sales file F1, the date data D1, and the event data E1.

The product master M1 is a master file that stores a "product name", a "product price", and the like in association with a "product code". Since the content of the product master M1 is updated daily, it is periodically received from the store server or the like via the communication I / F35. The specific data structure of the product master M1 will be described later (see FIG. 3).

The tax rate master M2 is a master file that stores the "tax category name" and the "tax rate" in association with the "tax category ID" of each tax category. The specific data structure of the tax rate master M2 will be described later (see FIG. 4).

The sales file F1 is a file that stores the result of the settlement processing performed by the POS terminal 2 as a sales history. The sales file F1 is transmitted to the store server via the communication I / F35 at a fixed time such as after the business is closed every day. The transmitted sales file F1 is used when the store server manages the sales of the store.

The date data D1 stores calendar information including at least the date. Since the CPU 31a originally has calendar information, the POS terminal 2 may acquire the date data D1 from the CPU 31a as needed. The date data D1 is an example of date information in the present disclosure.

The event data E1 stores event information (event content and holding time) performed at the facility attached to the store and the facility near the store in association with the date data D1. The event data E1 is an example of event information in the present disclosure. In addition, the event data E1 stores information related to laws and regulations related to tax rate setting, such as the enforcement date of the laws and regulations and the contents of the tax rate to be enforced. The POS terminal 2 acquires the latest information that the store server updates as appropriate as event data E1.

The I / O device control unit 34 includes a control unit 31, various peripheral devices, that is, a clerk monitor 14, a touch panel 15, a keyboard 13, a customer monitor 16, a bar code reader 19, a drawer 12, and a receipt. Connect to the printer 17. The I / O device control unit 34 controls each connected peripheral device based on a command from the control unit 31. The functions of each peripheral device are as described above.

The communication I / F35 is an interface for communicating with the store server via a network such as an in-store LAN (Local Area Network). Specifically, the control unit 31 of the POS terminal 2 communicates with the store server via the communication I / F35, and receives the product master M1 and the like stored in the store server. Further, the control unit 31 of the POS terminal 2 transmits the sales file F1 to the store server via the communication I / F35.

(Explanation of the structure of the product master and tax rate master)
FIG. 3 is a diagram showing a data structure of the product master. As shown in FIG. 3, the product master M1 stores product information such as a "product name" and a "price" of a product in association with a "product code" of each product. The product code is identification information uniquely set for each product and is used to identify the product. For example, in a store, the product code set for the product is written on the label attached to the product. Then, the POS terminal 2 inputs the product code described on the label with a bar code reader 19 or the like. The POS terminal 2 identifies the product by referring to the product master M1 with the input product code.

The product master M1 further stores identification information indicating whether the product is a product subject to the reduced tax rate. The reduced tax rate is a tax system defined by the government that reduces the consumption tax rate on the minimum necessary goods for daily life.

Depending on the consumption pattern, a tax corresponding to the standard tax rate may be levied on a specific product, or a tax corresponding to the reduced tax rate may be levied. For example, when a purchased product (food and drink) is eaten in a place where a food and drink facility is installed (eat-in), a consumption tax (for example, 10%) corresponding to the standard tax rate is levied. On the other hand, when the purchased product (food and drink) is brought back (takeout), a consumption tax (for example, 8%) corresponding to the reduced tax rate is levied.

FIG. 4 is a diagram showing a data structure of the tax rate master. As shown in FIG. 4, the tax rate master M2 stores the "tax category name" and the "tax rate" in association with the "tax category ID" of each tax category. The "tax classification ID" is identification information uniquely set for each tax classification. In the present embodiment, as described above, the type of consumption tax levied according to the purchase format of the product is set as the tax classification. Specifically, the consumption tax rates for the eat-in format and the take-out format are classified as tax categories. The "tax classification name" indicates the name of the tax classification identified by the "tax classification ID". FIG. 4 shows an example in which “take-out” representing take-out and “eat-in” representing in-store eating and drinking are set as the “tax classification name”. Further, the "tax rate" indicates the tax rate of the consumption tax applied to the "tax classification ID".

(Explanation of the functional configuration of the POS terminal)
FIG. 5 is a functional block diagram showing an example of the functional configuration of the POS terminal. The control unit 31 of the POS terminal 2 expands the control program P1 into the RAM 31c and operates it to change the default tax rate setting unit 41, the product registration processing unit 42, the tax rate change setting unit 43, and the tax rate change as shown in FIG. The setting release unit 44, the display control unit 45, the tax amount calculation unit 46, the print control unit 47, and the attribute acquisition unit 48 are realized as functional units.

At the start of the transaction, the default tax rate setting unit 41 uniquely sets the tax rate related to the transaction of the specific product with the first tax rate corresponding to the first purchase format or the first tax rate corresponding to the second purchase format. Set to one of the second tax rates associated with. The first purchase format is, for example, the case of purchasing a specific product in an eat-in format, and the first tax rate is 10%. The second purchase format is, for example, the case of purchasing a specific product in a take-out format, and the second tax rate is 8%. If the reduced tax rate is not enforced, the first tax rate corresponding to the first purchase type is 8%, and the second purchase type and the second tax rate do not exist. The default tax rate setting unit 41 is an example of the initial setting means in the present disclosure.

The product registration processing unit 42 performs a registration process for registering a product to be sold.

The tax rate change setting unit 43 changes the tax rate setting of the specific product from the tax rate setting set by the default tax rate setting unit 41 to the tax rate setting uniquely associated with the tax rate. Specifically, when the default tax rate is set to the first tax rate, the default tax rate setting unit 41 changes the tax rate setting to the second tax rate. On the other hand, when the default tax rate is set to the second tax rate, the default tax rate setting unit 41 changes the tax rate setting to the first tax rate. The tax rate change setting unit 43 is an example of the setting change means in the present disclosure.

The tax rate change setting release unit 44 cancels the tax rate setting changed by the tax rate change setting unit 43 and returns to the setting before the change. The tax rate change setting canceling unit 44 is an example of the setting change canceling means in the present disclosure.

At the time of product registration, the display control unit 45 displays on the clerk monitor 14 information indicating whether the tax rate is calculated corresponding to the eat-in format or the tax rate is calculated corresponding to the take-out format. In addition, the display control unit 45 displays on the customer monitor 16 information indicating whether the tax rate calculation corresponding to the eat-in format or the tax rate calculation corresponding to the take-out format is performed at the time of product registration. The display control unit 45 is an example of the display means in the present disclosure.

The tax amount calculation unit 46 waits until the tax rate change setting unit 43 makes the tax rate change setting or the tax rate change setting cancellation unit 44 cancels the tax rate setting change during one transaction. , The tax amount of the specific product is calculated based on the tax rate set before the change setting or before the cancellation of the setting change. The tax amount calculation unit 46 is an example of the tax amount calculation means in the present disclosure.

The print control unit 47 prints the store name and contact information of the store, the product name, price, tax amount, etc. of each product registered by the product registration processing unit 42 on the receipt paper by the receipt printer 17.

The attribute acquisition unit 48 acquires the attribute information related to the operation of the store from the date data D1 and the event data E1 stored in the storage unit 32. The attribute information related to the operation of the store is, for example, the enforcement date of the law concerning the tax rate setting, the event information performed at the facility near the store, and the like. The attribute acquisition unit 48 is an example of acquisition means in the present disclosure. In the present embodiment, the attribute acquisition unit 48 acquires the status of the tax system on the day and the information on the holding of the event on the day at the facility attached to the store and the facility near the store as specific attribute information. That is, the status of the tax system on the day and the information on the holding of the event on the day are examples of the attribute information in the present disclosure.

(Explanation of initial tax rate setting method)
A method in which the POS terminal 2 performs initial setting of the tax rate and determines the default tax rate will be described with reference to FIG. FIG. 6 is a diagram illustrating a method of determining a default tax rate setting. In particular, FIG. 6 is a diagram illustrating a method of setting a default tax rate, taking as an example a POS terminal 2 installed in a store that sells food and drink, which is attached to a baseball stadium.

The default tax rate setting unit 41 sets the default tax rate based on the status of the tax system on the day of sale and the consumption behavior of the customer on the day of sale.

The status of the tax system on the day of sale, for example, the change date of the tax system, is stored in the storage unit 32 as event data E1 associated with the date data D1 by storing the specific set tax rate notified in advance. It shall be.

On days when an event is held at a store attached to a baseball stadium or at an event venue adjacent to the store, most customers consume the food and drink purchased at the store at the baseball stadium or nearby event venues. That is, eat in. Therefore, on the event date, the POS terminal 2 often calculates the tax rate corresponding to the eat-in format.

On the other hand, on days when the event is not held at the store attached to the baseball stadium or at the event venue adjacent to the store, most customers consume, that is, take out, the food and drink purchased at the store outside the venue. Therefore, on non-event days, the POS terminal 2 often calculates the tax rate at the tax rate corresponding to the take-out format.

Therefore, the POS terminal 2 of the present embodiment utilizes the presence or absence of the event on the day of sale acquired from the event data E1 for the default tax rate setting. Specifically, if the day is the event date, the default tax rate is set to the tax rate corresponding to the eat-in format. If the day is not an event day, the default tax rate is set to the tax rate corresponding to the takeout format.

The table T1 shown in FIG. 6 is an example of a table in which the date data D1 stored in the storage unit 32 and the event data E1 are associated with each other. That is, the table T1 shows the status of the tax system corresponding to the date and the presence / absence of event information. For example, Table T1 shows that the reduced tax rate will come into effect on October 1, 2019. Although not shown in FIG. 6, table T1 is subject to a 10% consumption tax when the product is purchased in the eat-in format due to the reduced tax rate, and the product is in the take-out format. It is assumed that you remember that 8% consumption tax will be levied when you make a purchase.

The default tax rate setting unit 41 sets the default tax rate at the start of the transaction by referring to the table T1.

Specifically, if the sale date of the product is before October 1, 2019, the reduced tax rate is not enforced, so the default tax rate setting unit 41 changes the tax rate and takeout format corresponding to the eat-in format. Recognize that the corresponding tax rates are both 8%. Therefore, the default tax rate setting unit 41 sets the default set tax rate to 8% regardless of whether or not an event is held. That is, the first tax rate corresponding to the second purchase format is set to 8%. Further, the default tax rate setting unit 41 sets that there is no second tax rate corresponding to the second purchase format.

In addition, when the sale date of the product is after October 1, 2019, the default tax rate setting unit 41 will implement the reduced tax rate on October 1, 2019 from the event data E1, and the tax rate corresponding to the eat-in format. Is 10%, and the tax rate corresponding to the take-out format is 8%. Then, the default tax rate setting unit 41 sets the default set tax rate to 10% for the event date. That is, the first tax rate corresponding to the first purchase format is set to 10%. Further, the default tax rate setting unit 41 sets the second tax rate corresponding to the second purchase format to 8%.

In this way, the default tax rate setting unit 41 sets the tax rate at the start of transaction (default tax rate) and the tax rate when the tax rate is changed by the tax rate change setting unit 43, as shown in Table T2 of FIG. That is, the tax rate at the time of change setting is set.

If the event data E1 includes the event holding time, the default set tax rate can be changed according to the time even on the same sales date. For example, even if the event is held on the same date, if the transaction starts at a time between 2 hours before the event start time and the event end time, the tax rate (10%) corresponding to the eat-in format is set as the default. It can be a tax rate. On the other hand, if the transaction is started at any other time, the tax rate corresponding to the take-out format can be set as the default set tax rate.

(Explanation of screen display of POS terminal)
The contents of the screen display that the POS terminal 2 displays on the store clerk monitor 14 and the customer monitor 16 will be described with reference to FIGS. 7A to 7E. 7A to 7E are diagrams showing an example of a screen displayed on the clerk monitor and the customer monitor during the transaction. Each of FIGS. 7A to 7E shows a screen displayed on the store clerk monitor 14 (touch panel 15) and a screen displayed on the customer monitor 16 together. The store clerk monitor 14 and the customer monitor 16 have substantially the same size as shown in FIG. 1, but the sizes are changed for convenience of explanation.

First, various information displayed on the store clerk monitor 14 and the customer monitor 16 will be described with reference to FIG. 7A.

The store clerk monitor 14 displays four types of windows: a product information display window W1, a purchase price display window W2, an operation window W3, and a 10-key window W4.

The product information display window W1 displays the product information registered by the product registration processing unit 42 of the POS terminal 2. Specifically, the product information display window W1 has a standard product code 50a, a product name 50b, a unit price 50c, a number of purchases 50d, a discount amount 50e, a purchase amount 50f, and tax-included / tax-excluded 50g. The tax rate / reduced tax rate 50h and the tax rate setting state 50i are displayed.

The product code 50a indicates the product code of the registered product. The product name 50b indicates the product name of the registered product. The unit price 50c indicates the unit price of the registered product. The number of purchased points 50d indicates the number of points when the same product is registered more than once.

Further, the discount amount 50e indicates the discount amount of the registered product. The purchase price 50f indicates a subtotal price for one type of registered product. The tax-included / tax-excluded 50 g indicates whether the registered product is a tax-included product or a tax-excluded product. If the registered product is a tax-included product, "inside" is displayed for the tax-included / tax-excluded 50g. If the registered product is a tax-excluded product, "outside" is displayed for the tax-included / tax-excluded 50g. The standard tax rate / reduced tax rate 50h indicates whether the registered product is a product subject to the standard tax rate or a product subject to the reduced tax rate. An example in which information is actually displayed at the standard tax rate / reduced tax rate 50h will be described later (see FIGS. 7B, 7C, and 7D).

The tax rate setting state 50i is information indicating that the POS terminal 2 has the take-out or eat-in setting as the default setting. In the example of FIG. 7A, it is shown that the tax rate (10%) corresponding to the eat-in format, which is the default setting, is set.

Then, in FIG. 7A, the information related to the actually registered product is displayed in the column 70a.

The purchase amount display window W2 displays the purchase amount and the like based on the result of product registration by the product registration processing unit 42 of the POS terminal 2.

The operation window W3 displays operation keys for operating the POS terminal 2. In the example of FIG. 7A, the operation window W3 includes an operation window W3a displayed at the lowermost part of the clerk monitor 14 and an operation window W3b displayed at the upper right part of the clerk monitor 14. Pressing the operation key displayed on the operation window W3 is transmitted to the POS terminal 2 detected by the touch panel 15. Then, the POS terminal 2 performs a process corresponding to the pressed operation key.

The operation window W3a mainly displays operation keys for performing maintenance management of the POS terminal 2. In the operation window W3b, operation keys for causing the POS terminal 2 to perform registration processing and payment processing are mainly displayed.

A part of the operation keys may be arranged on the keyboard 13 (see FIG. 1). Further, in order to improve operability, the same operation keys may be set in both the operation window W3 and the keyboard 13 so that they can be operated by any operation unit.

In particular, the POS terminal 2 of the present embodiment includes the tax type declaration key 60a in the operation window W3 (W3b). The tax type declaration key 60a is a key for declaring a change in the current tax rate setting. That is, when the tax type declaration key 60a is pressed in the state of FIG. 7A, the POS terminal 2 is set to calculate the tax amount at the tax rate (10%) corresponding to the eat-in formation, and at the tax rate (8%) corresponding to the take-out format. It will be changed to the setting to calculate the tax amount. The type and arrangement position of the operation keys displayed on the operation window W3 can be freely set by the POS terminal 2.

The 10-key window W4 displays 10 keys to be used when inputting numerical values, such as when registering a plurality of the same products or when inputting an amount of money received from a customer. Further, the 10-key window W4 displays a subtotal key, a deposit / current total key, and the like. The operation keys displayed on the 10-key window W4 may be arranged on the keyboard 13.

Then, when the store clerk monitor 14 is in the state of FIG. 7A, the display control unit 45 displays on the customer monitor 16 information indicating that the tax amount is calculated in the eat-in format, which is the default setting. Further, the display control unit 45 displays on the customer monitor 16 information indicating that the store clerk is requested to take the product home.

Next, using FIG. 7B, the screen state of the POS terminal 2 when the product purchased by the customer is registered in the eat-in setting will be described.

In FIG. 7B, information relating to the actually registered product is displayed in the column 70b. In this case, since the registered product is a target product (specific product) for eat-in, "food" indicating eat-in is displayed in the item of the standard tax rate / reduced tax rate 50h.

Further, in the state of FIG. 7B, the tax rate (10%) corresponding to the eat-in format, which is the default setting, is set in the POS terminal 2, so that the reduced tax rate is set in the tax rate setting state 50i, as in FIG. 7A. , Indicates that the settings correspond to the default eat-in format. Further, the tax type declaration key 60a is marked with the notation “takeout” following FIG. 7A.

The display of the customer monitor 16 is maintained in the state of FIG. 7A.

FIG. 7C is a screen example showing an example of a state in which the default setting for tax rate calculation, that is, the eat-in setting is canceled at the request of the customer.

The clerk presses the tax type declaration key 60a (FIG. 7B) in response to the customer's offer to "take home the product". Then, the tax rate change setting unit 43 changes from the tax rate setting (eat-in setting: tax rate 10%) set by the default tax rate setting unit 41 to a tax rate setting (take-out setting: tax rate 8%) different from the tax rate. At this time, the display control unit 45 changes the tax type declaration key 60a to the tax type declaration key 60b with the notation "eat-in".

Further, since the default tax rate setting (eat-in setting) of the POS terminal 2 is canceled, the display control unit 45 erases the tax rate setting state 50i (FIG. 7B). In addition, in order to make the current tax rate setting state easier to understand, the tax rate setting state 50i may be displayed as "takeout" in FIG. 7C.

In addition, the display control unit 45 displays information indicating that the tax amount is calculated in the take-out format on the customer monitor 16. Further, the display control unit 45 displays on the customer monitor 16 information indicating that the customer is offered to eat or drink in the store.

FIG. 7D is an example of a screen when the target product for takeout is registered as a product in a state where the default setting is canceled and the setting is changed to the takeout setting.

That is, as shown in FIG. 7D, the information related to the actually registered product is displayed in the column 70c. In this case, since the registered product is a take-out target product (specific product), "light" indicating that the product corresponds to the reduced tax rate due to take-out is displayed in the item of the standard tax rate / reduced tax rate 50h.

The display of the customer monitor 16 is maintained in the state shown in FIG. 7C.

(Explanation of the processing flow performed by the POS terminal)
FIG. 8 is a flowchart showing an example of the flow of processing performed by the POS terminal according to the embodiment. First, the flow of processing of the main routine composed of steps S10 to S16 will be described with reference to FIG.

The default tax rate setting unit 41 performs a tax rate default setting process (step S10). The details of the tax rate default setting process will be described later (see FIG. 9).

The display control unit 45 displays the tax rate setting status on the store clerk monitor 14 and the customer monitor 16 (step S11). Specifically, the display control unit 45 displays the tax rate setting state 50i on the clerk monitor 14 (see FIG. 7B). Further, the display control unit 45 displays information according to the tax rate setting state on the customer monitor 16 (see FIGS. 7A and 7C).

The product registration processing unit 42 performs a product registration process for registering a product purchased by the customer (step S12).

Next, when the registered product is a specific product, the tax amount calculation unit 46 of the product registered in step S12 based on the tax rate set by the tax rate change setting unit 43 or the tax rate change setting cancellation unit 44. The tax amount is calculated (step S13). Although not shown in FIG. 8, if the registered product is not a specific product, the tax amount calculation unit 46 calculates the tax amount at the standard tax rate.

The display control unit 45 displays the information related to the registered product on the clerk monitor 14 (step S14).

The product registration processing unit 42 determines whether the registration of all the products has been completed (step S15). When it is determined that the registration of all the products is completed (step S15: Yes), the process proceeds to step S16. On the other hand, if it is not determined that the registration of all the products is completed (step S15: No), the process returns to step S11.

If it is determined to be Yes in step S15, the print control unit 47 instructs the receipt printer 17 to print the transaction result and issue the receipt (step S16). After that, the POS terminal 2 ends the series of processes shown in FIG.

The POS terminal 2 executes the two types of interrupt processing shown in FIG. 8 while performing the processing of the main routine described above.

The first interrupt process is a process of giving an instruction to change the set tax rate setting to the POS terminal 2.

Specifically, the tax rate change setting unit 43 determines whether or not the tax type declaration key 60a is pressed while the default tax rate is set (step S20). When it is determined that the tax type declaration key 60a has been pressed (step S20: Yes), the process proceeds to step S21. On the other hand, if it is not determined that the tax type declaration key 60a is pressed (step S20: No), the interrupt process is terminated and the process returns to the main routine.

If Yes is determined in step S20, the tax rate change setting unit 43 changes the tax rate setting (step S21). After that, the interrupt process is finished and the main routine is returned.

The second interrupt process is a process of giving an instruction to cancel the tax rate setting change to the POS terminal 2.

Specifically, the tax rate change setting canceling unit 44 determines whether the tax type declaration key 60a has been pressed while the tax rate change setting has been made (step S30). When it is determined that the tax type declaration key 60a has been pressed (step S30: Yes), the process proceeds to step S31. On the other hand, if it is not determined that the tax type declaration key 60a is pressed (step S30: No), the interrupt processing is terminated and the process returns to the main routine.

If Yes is determined in step S30, the tax rate change setting canceling unit 44 cancels the tax rate change setting (step S31). After that, the interrupt process is finished and the main routine is returned.

(Explanation of the flow of tax rate default setting process)
Next, the flow of the tax rate default setting process will be described with reference to FIG. FIG. 9 is a flowchart showing an example of the flow of the tax rate default setting process performed by the POS terminal according to the embodiment.

The default tax rate setting unit 41 acquires the date data D1 and the event data E1 from the storage unit 32 (step S40).

The default tax rate setting unit 41 determines whether the date of the current day based on the calendar information possessed by the CPU 31a is the reduced tax rate application date (step S41). When it is determined that the day is the date on which the reduced tax rate is applied (step S41: Yes), the process proceeds to step S42. On the other hand, if it is not determined that the day is the reduced tax rate application date (step S41: No), the process proceeds to step S44. Whether or not the current day is the reduced tax rate application date is determined by referring to the event data E1 corresponding to the date of the current day indicated by the date data D1.

If it is determined Yes in step S41, the default tax rate setting unit 41 determines whether the day is the event date (step S42). When it is determined that the day is the event date (step S42: Yes), the process proceeds to step S43. On the other hand, if it is not determined that the day is the event date (step S42: No), the process proceeds to step S44. Whether or not the current day is the event date is determined by referring to the event data E1 corresponding to the date of the current day indicated by the date data D1.

If Yes is determined in step S42, the default tax rate setting unit 41 sets the eat-in tax rate (10%) as the default value of the tax rate (step S43). After that, the process of FIG. 9 is finished, and the process returns to step S11 of the main routine.

If No is determined in step S41 or step S42, the default tax rate setting unit 41 sets the take-out tax rate (8%) as the default value of the tax rate (step S44). After that, the process of FIG. 9 is finished, and the process returns to step S11 of the main routine.

Although not explicitly shown in the flowchart of FIG. 8, the tax rate default setting process shown in FIG. 9 may be executed only when the main routine shown in FIG. 8 is first operated on the day. When the main routine is executed from the second time onward, the default value of the tax rate set and stored in the first operation is applied.

As described above, in the POS terminal 2 (commodity sales data processing device) of the embodiment, the default tax rate setting unit 41 (initial setting means) first purchases the tax rate related to the transaction of the specific product at the start of the transaction. Set to either the first tax rate corresponding to the format or the second tax rate uniquely associated with the first tax rate corresponding to the second purchase format. Then, from the setting of the first tax rate or the second tax rate to the change to the second tax rate or the first tax rate by the tax rate change setting unit 43 (setting change means), the tax amount calculation unit 46 (tax amount). The calculation means) calculates the tax amount of a specific product based on the tax rate setting before the setting change. Further, until the tax rate change setting canceling unit 44 (setting change canceling means) cancels the tax rate setting and returns to the setting before the change, the tax amount calculation unit 46 (tax amount calculating means) is before the setting change is canceled. Calculate the tax amount of a specific product based on the tax rate setting of. Then, the display control unit 45 (display means) displays the set tax rate on the clerk monitor 14 and the customer monitor 16. Therefore, it is not necessary to confirm the tax rate each time a specific product is registered, so that the product registration operation of the product subject to the reduced tax rate can be simplified.

Further, in the POS terminal 2 (product sales data processing device) of the embodiment, the attribute acquisition unit 48 (acquisition means) acquires the attribute information related to the operation of the store. Then, the default tax rate setting unit 41 (initial setting means) sets the first tax rate or the second tax rate as the tax rate at the start of the transaction based on the attribute information acquired by the attribute acquisition unit 48. Therefore, the tax rate that is expected to be applied to more customers based on the consumption behavior of the customers who use the store can be set as the default tax rate.

Further, in the POS terminal 2 (commodity sales data processing device) of the embodiment, the attribute information is the enforcement date of the law concerning the tax rate setting. Therefore, the default tax rate can be set based on the tax rate applied on the day.

Further, in the POS terminal 2 (product sales data processing device) of the embodiment, the attribute information is event information performed in the vicinity of the store. Therefore, the default tax rate can be set based on information that affects the consumption behavior of customers such as holding and not holding an event.

Further, in the POS terminal 2 (product sales data processing device) of the embodiment, the first purchase format is a purchase format in which a specific product is consumed in the store, and the second purchase format is a purchase in which the specific product is brought back. The format. Therefore, when the same product is purchased, the product registration operation related to the setting of whether to apply the eat-in type tax rate (standard tax rate) or the take-out type tax rate (reduced tax rate) can be simplified.

In the present embodiment, the case where the tax rate is different at the time of eat-in and at the time of take-out has been described as an example, but the present invention is not limited to this situation. For example, the present invention can be applied to cases where the tax rate differs depending on whether the same product is purchased individually or in bulk. In such a case, the history of past consumption behavior of the customer can be used as the attribute information. Then, from the past history, when there are many customers who buy in bulk, the tax rate corresponding to the bulk buying can be set as the default tax rate setting.

Further, in the present embodiment, when a specific product is purchased, the case where the tax rate differs between the first purchase type and the second purchase type (that is, the case where the tax rate is set to two types) has been described. It can be applied even when there are three or more types of settings.

For example, it is assumed that the tax rate is set according to the number of purchases of a specific product and the consumption form. That is, the tax rate is 15% when the number of purchases of a specific product is less than 5 and eat-in, the tax rate is 10% when the number of purchases is 5 or more and eat-in, and the number of purchases is less than 5 and take-out. Is a case where the tax rate is set to 12%, the number of purchased items is 5 or more, and the tax rate is set to 8% in the case of takeout. In this case, there are four types of tax rate settings.

Even in such a case, in the POS terminal 2 (commodity sales data processing device), the default tax rate setting unit 41 sets the default tax rate based on the event data E1 and the past consumer behavior. Then, the tax rate change setting unit 43 (setting change means) can change the setting of the tax rate uniquely associated with the purchase number of the specific product and the consumption form. Further, the tax rate change setting canceling unit 44 (setting change canceling means) cancels the tax rate setting and returns to the tax rate setting before the change, or is uniquely associated according to the number of purchased specific products and the consumption form. You can return to the tax rate setting.

Although the embodiment of the present invention has been described above, this embodiment is an example and is not intended to limit the scope of the invention. This novel embodiment can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
