Description

The present invention relates to a sales data processing device and a program.

From October of the first year of Reiwa, a reduced tax rate system was introduced for consumption tax, and there are two tax rates, the standard tax rate and the reduced tax rate. The tax rate may differ depending on the method of provision (sales mode) of even one product. For example, the reduced tax rate is applied when foods that are taken home and eaten are sold, but the standard tax rate is applied when the foods are sold as foods that are eaten or eaten in the store. For this reason, when registering sales of a product using an electronic register, the clerk needs to distinguish between a product that eats and drinks in the store (in-store food and drink product) and a product that can be taken home (take-out product) and registers the sales. ..

In the product data processing device (electronic register) described in Patent Document 1, even the same product is registered as a product by tax (see the product setting screens shown in FIGS. 5 and 6 of Patent Document 1). Further, the product selection button displayed on the touch panel display is divided into a product selection button for a product to which the standard tax rate is applied and a product selection button for the product to which the reduced tax rate is applied even for the same product (see FIG. 8 of Patent Document 1).

Japanese Unexamined Patent Publication No. 2017-1676999

As long as the electronic register has a storage unit with a sufficient capacity, even the same product can be registered as a different product by tax. However, such a method cannot be adopted for an electronic register in which the capacity of the storage unit is insufficient or an electronic register in which the number of products that can be registered is limited.
The present invention has been made in view of such a background, and an object of the present invention is to provide a sales data processing device and a program capable of dealing with a plurality of tax rates while suppressing an increase in storage capacity.

In order to solve the above problems, the sales data processing device according to the present invention is a sales data processing device capable of allocating a memory area for totaling the sales amount or the number of sales for each type of product, and the sales should be totaled. Switching means for switching between the first sales mode when the product type includes the type of product whose consumption tax rate can be switched according to the sales mode and the second sales mode which does not require switching of the consumption tax rate. And, when the memory area allocated to the predetermined product type when the second sales mode is set by the switching means is switched to the first sales mode by the switching means, the consumption tax rate is set. It is characterized in that it is provided with a division means for dividing and setting a plurality of sub-memory areas in correspondence with the above.

According to the present invention, it is possible to provide a sales data processing device and a program capable of dealing with a plurality of tax rates while suppressing an increase in storage capacity.

It is a flowchart of the memory setting process executed by the CPU which concerns on the modification of this embodiment.

The electronic register (sales data processing device) according to the embodiment of the present invention will be described below. In general, electronic registers use the cumulative number of units sold (cumulative number of units sold) and the amount of sales (cumulative sales amount) for each product (also referred to as the type of product) in order to perform a settlement process that aggregates sales and outputs a sales report. I remember. If the consumption tax rate is different even for the same product, it is necessary to total the cumulative number of units sold and the cumulative sales amount for each consumption tax rate.

In the electronic register according to the present embodiment, for a product having a plurality of tax rates, a memory area having the same size as that of a product having a tax rate is divided, and each divided memory area is assigned to each of the plurality of tax rates, resulting in cumulative sales. Store the number and cumulative sales amount. For example, the electronic register divides the area for storing the cumulative sales amount into two, stores the cumulative sales amount as the reduced tax rate applied product on one side, and stores the cumulative sales amount as the standard tax rate applied product on the other side.

By doing so, it is possible to perform sales registration processing and settlement processing corresponding to a plurality of tax rates without increasing the storage capacity. When almost all products are sold as take-out products and in-store food and drink products, such as fast food stores, a memory that stores the cumulative number of units sold and the cumulative sales amount for each product with the introduction of the reduced tax rate system. Double the capacity is required for the area. If there is not enough memory area, it will be necessary to increase the memory or replace the electronic register. However, in the electronic register according to the present embodiment, there is no need to add memory or replace the product, and sales registration processing and settlement processing can be performed for all products.

≪Composition of electronic register≫

When the take-out key 173 is pressed after the product number is entered on the numeric keypad 171, the product corresponding to the product number is registered as a take-out product. When the in-store key 174 is pressed after the product number is entered with the numeric keypad 171, the product corresponding to the product number is registered as sales of the in-store food and drink product.

When the PLU key 172 is pressed after the product number is entered with the numeric keypad 171, the product corresponding to the product number is registered as sales. When a product sold as a take-out product or an in-store food / drink product is registered for sales with the PLU key 172, if the product registered for sales before that is registered as an in-store food / drink product, the sales are registered as an in-store food / drink product. If it is registered as a take-out product, it will be registered as a take-out product.

If there are a plurality of products, the number is entered with the numeric keypad 171 and then the x key 177 is pressed, and then the product number is entered. When the subtotal key 175 is pressed, the subtotal of the product registered for sales is derived and displayed on the display unit 160. In the case of payment by cash, the current / deposit key 176 is pressed after the cash amount is entered with the numeric keypad 171.

Returning to FIG. 1, the storage unit 120 includes a RAM (Random Access Memory) 121 and a ROM (Read Only Memory) 122. The ROM 122 stores the program 129, the product list 130, and the sales settlement data 140. The electronic register 100 is a computer, and when the CPU 110 executes the program 129, the tax rate setting process (see FIG. 6 described later), the sales registration process (see FIGS. 7, 8 and 10 described later) and the settlement process (see FIG. (See FIG. 11 described later) and print the sales report (see FIG. 12 described later).

≪Product list structure≫
FIG. 4 is a data structure diagram of the product list 130 according to the present embodiment. In the product list 130, products to be processed for sales registration are registered. The product list 130 is, for example, tabular data, and one row (record) indicates one product. The record of the product list 130 includes a product number 131 (denoted as “product #” in FIG. 4), a product name 132, a price 133, a tax rate category 134, and a memory setting 135.

The product number 131 is a product identification number, which is a number entered by the numeric keypad 171 (see FIG. 3) when registering sales. The product name 132 is the name of the product. Price 133 is the price excluding tax.
The tax rate category 134 indicates the type of tax to be applied. The tax rate category 134 of food products to which the reduced tax rate is applied in the case of take-out and the standard tax rate is applied in the case of in-store eating and drinking is "mark / light". In addition, there are "standard" indicating the consumption tax of the standard tax rate, "reduced" indicating the consumption tax of the reduced tax rate, and "no" indicating the tax exemption. When the tax rate classification 134 of a product is "mark / light", the product is described as a product having a plurality of tax rates, a product to which a plurality of tax rates are applied, and the like. In the present embodiment, the standard tax rate will be 10% and the reduced tax rate will be 8%.

The memory setting 135 divides the memory area 140A-2 (see FIG. 5 described later) for storing the cumulative sales quantity and the memory area 140A-3 for storing the cumulative sales amount (“split”) or does not divide (“split”). "Undivided"). If the tax rate category 134 is "mark / light", the memory setting 135 is set to "split" (first setting), and if the tax rate category 134 is not "mark / light", the memory setting 135 is "non". It is set to "split" (second setting) (see FIG. 6 described later).

Record 138 indicates "fried chicken" whose product number 131 is "101", the price excluding tax is 250 yen, and either the standard tax rate or the reduced tax rate is applied, and the memory areas 140A-2,140A It shows that -3 is divided. Record 139 indicates that the item number 131 indicates a "towel" of "412", the tax-excluded price is 480 yen, the standard tax rate is applied, and the memory areas 140A-2 and 140A-3 are not divided. There is.

≪Structure of sales settlement data≫
FIG. 5 is a diagram showing a memory layout of the total memory area 140A for storing the sales settlement data 140 according to the present embodiment. In the sales settlement data 140 (total memory area 140A), for example, the cumulative number of sales for one day and the cumulative sales amount are stored for each product (also referred to as the type of product). The sales settlement data 140 (total memory area 140A) is, for example, tabular data, and one row (record) indicates one product (product type) registered for sales. The record of the total memory area 140A (memory area allocated to one product) includes the product number, the cumulative number of units sold, and the memory area allocated to the cumulative sales amount.

The product number is stored, for example, in the 2-byte memory area 140A-1 as a 16-bit (2-byte) unsigned integer.
If the product is a multiple tax rate product and the memory setting 135 is "split", the cumulative number of units sold as a reduced tax rate product (take-out product) is in the memory area 140A-2-1 and the standard tax rate product (in-store food and drink product). Is stored in the memory area 140A-2-2 in BCD (Binary-Coded Decimal) format. Further, the cumulative sales amount as the reduced tax rate product is stored in the memory area 140A-3-1, and the cumulative sales amount as the standard tax rate product is stored in the memory area 140A-3-2 in the BCD format. If the product is a standard tax rate product, a reduced tax rate product, or a tax-exempt product (tax-free product) and the memory setting 135 is "non-divided", the cumulative sales quantity is in the memory area 140A-2 and the cumulative sales amount is in the memory area. It is stored in 140A-3 in BCD format.

The memory capacities of the memory areas 140A-2-1 to 140A-3-2 are 2.5 bytes, respectively, and the memory capacities of the memory areas 140A-2 and 140A-3 are 5 bytes, respectively. As shown in FIG. 5, the memory area 140A-2 (memory area) is divided (allocated) into the memory areas 140A-2-1 and 140A-2-2 (sub-memory areas). Further, the memory area 140A-3 (memory area) is divided (allocated) into the memory areas 140A-3-1 and 140A-3-2 (sub-memory areas). The memory capacity (memory size) of the memory area allocated to one product regardless of the plurality of tax rate products, the standard tax rate product, the reduced tax rate product, and the tax exempt product is 12 bytes, which is the same memory capacity.

In a multi-tax rate product, when the memory setting 135 is "split", the memory area 140A-2 (memory area) with a memory capacity of 5 bytes for storing the cumulative number of units sold has a memory capacity of 2.5 bytes each. It is divided (allocated) into memory areas 140A-2-1 and 140A-2-2 (sub-memory areas), and the cumulative number of units sold as reduced tax rate products is stored in memory area 140A-2-1. Cumulative number of units sold as standard tax rate products is stored in 2-2. Similarly, the memory area 140A-3 (memory area) having a memory capacity of 5 bytes for storing the cumulative sales amount is the memory area 140A-3-1, 140A-3-2 (memory area) having a memory capacity of 2.5 bytes each. It is divided (allocated) into (sub-memory areas), and the cumulative sales amount as a reduced tax rate product is stored in the memory area 140A-3-1, and the cumulative sales amount as a standard tax rate product is stored in the memory area 140A-3-2. Will be done.

The memory area 148 stores the cumulative number of units sold and the cumulative sales amount of the "potato S" whose product number 131 (see FIG. 4) is "102". Specifically, the cumulative number of units sold as a reduced tax rate product is four and the cumulative sales amount is 864 yen, and the cumulative number of units sold as a standard tax rate product is one and the cumulative sales amount is 220 yen.
The memory area 149 stores the cumulative sales quantity and the cumulative sales amount of the "towel" whose product number 131 is "412". Specifically, the cumulative number of units sold is two and the cumulative sales amount is 1056 yen.

≪Tax rate setting process≫
The products to be processed for sales registration are registered in advance in the product list (FIG. 4). Specifically, the clerk who is the user of the electronic register 100 registers the product number 131, the product name 132, the price 133, and the tax rate classification 134 for each product, excluding the memory setting 135. The tax rate setting process executed by the CPU 110 when the tax rate category 134 is registered (set) will be described below.

FIG. 6 is a flowchart of the tax rate setting process executed by the CPU 110 according to the present embodiment.
In step S11, the CPU 110 as a setting means accepts the registration of the tax rate category 134 by the operation of the clerk, and if the tax rate category 134 is set to "mark / light" (step S11 → mark / light), the process proceeds to step S12. If it is set to other than "mark / light" (step S11 → other), the process proceeds to step S13.
In step S12, the CPU 110 as the allocation means sets the memory setting 135 to "division" (first setting).
In step S13, the CPU 110 as the allocation means sets the memory setting 135 to "non-divided" (second setting).

≪Sales registration process≫
FIG. 7 is a flowchart of the sales registration process executed by the CPU 110 according to the present embodiment. As described with reference to FIG. 3, after the product number is input with the numeric keypad 171, the PLU key 172, the take-out key 173, or the in-store key 174 is pressed to register the product with the product number. When a plurality of the same products are registered, the numeric keypad 171 indicating the number of products, the × key 177, the numeric keypad 171 indicating the product number, the PLU key 172, the take-out key 173, or the in-store key 174 are pressed. For example, when there are five products with the product number "123", the "5" key, the x key 177, the "1" key, the "2" key, the "3" key, and the PLU key 172 are pressed in this order.

In step S21, the CPU 110 determines the pressed key and proceeds to any of steps S22 to S27. Specifically, if the pressed key is the numeric keypad 171 (step S21 → numeric keypad), the process proceeds to step S22, if the key is the subtotal key 175 (step S21 → subtotal), the process proceeds to step S23, and if the key is the PLU key 172 (step S21 → subtotal). S21 → PLU) Proceed to step S24. Further, if the pressed key is the take-out key 173 (step S21 → take-out), the CPU 110 proceeds to step S25, if the pressed key is the in-store key 174 (step S21 → in-store), the process proceeds to step S26, and if the x key 177 is (step). S21 → ×) Proceed to step S27.

In step S22, the CPU 110 updates the number stored in the RAM 121 according to the pressed numeric keypad 171. For example, if the stored number is cleared and the "1" key is pressed, the CPU 110 updates and stores it as "1". If "12" is stored and the "3" key is pressed, the CPU 110 updates and stores the number "123".
In step S23, the CPU 110 executes a tightening process (see FIG. 8 described later).
In step S24, the CPU 110 executes an addition process (see FIG. 10 described later).

In step S25, the CPU 110 sets the take-out mode and proceeds to step S24. In the take-out mode, multiple tax rate products are registered as sales of take-out products.
In step S26, the CPU 110 sets the in-store eating and drinking mode and proceeds to step S24. In the in-store food and drink mode, sales of multiple tax rate products are registered as in-store food and drink products.
In step S27, the CPU 110 stores the number updated in step S22 and stored in the RAM 121 as the number of products in the RAM 121. Subsequently, the CPU 110 clears the number updated in step S22 and stored in the RAM 121.

FIG. 8 is a flowchart of a tightening process (see step S23 described in FIG. 7) executed by the CPU 110 according to the present embodiment.
In step S31, the CPU 110 derives the total amount (final subtotal amount) and the tax amount of the products registered for sales.
In step S32, the CPU 110 displays the final subtotal amount and the tax amount of the derived product on the display unit 160.

In step S33, the CPU 110 acquires the deposit amount. The deposit amount is entered by pressing the numeric keypad 171 and the current / deposit key 176 (see FIG. 3).
In step S34, the CPU 110 derives the fishing amount and displays the deposit amount and the fishing amount on the display unit 160.
In step S35, the CPU 110 prints a receipt (see FIG. 9 described later).

FIG. 9 is a diagram showing a receipt according to the present embodiment. The product name, quantity, amount, subtotal amount, standard tax rate consumption tax amount, reduced tax rate consumption tax amount, total amount, deposit amount, and fishing amount are printed.

FIG. 10 is a flowchart of an addition process (see step S24 described in FIG. 7) executed by the CPU 110 according to the present embodiment.
In step S41, the CPU 110 identifies the product. Specifically, the CPU 110 identifies the product with the product number 131 (see FIG. 4) corresponding to the number stored in the RAM 121 in step S22.
In step S42, the CPU 110 proceeds to step S43 if the memory setting 135 of the specified product is "divided" (step S42 → divided), and proceeds to step S53 if it is "non-divided" (step S42 → undivided).

In step S43, the CPU 110 proceeds to step S44 (step S43 → in-store) if it is in-store eating and drinking mode (see step S26 in FIG. 7), and goes to step S49 (step S43 → take-out) if it is in take-out mode (see step S25). move on.
In step S44, the CPU 110 derives the amount of goods and the amount of consumption tax. Specifically, the CPU 110 derives the consumption tax amount by multiplying the price 133 of the product specified in step S41 by the standard tax rate. Next, the CPU 110 derives the amount by adding the consumption tax amount to the price 133. If the number is 2 or more in step S27 (see FIG. 7), the consumption tax amount and the amount are each multiplied by the number.

In step S45, the CPU 110 derives and displays the subtotal amount and the tax amount. Specifically, the CPU 110 adds the amount derived in step S44 to the subtotal amount to newly derive the subtotal amount. Next, the CPU 110 adds the consumption tax amount derived in step S44 to the tax amount to newly derive the tax amount. The subtotal amount and the tax amount are stored in the RAM 121.

In step S46, the CPU 110 determines whether or not the memory areas 140A-2-2 and 140A-3-2 overflow. Specifically, the CPU 110 has a memory area 140A-2-2 for storing the cumulative number of units sold as a standard tax rate product in the total memory area 140A (see FIG. 5) corresponding to the specified product, and a cumulative sales amount as a standard tax rate product. With reference to the memory area 140A-3-2 for storing the above, it is determined whether the memory areas 140A-2-2 and 140A-3-2 overflow when the number and the amount derived in step S44 are added. If both of the memory areas 140A-2-2 and 140A-3-2 do not overflow the digits (step S46 → NO), the process proceeds to step S47, and if any of the memory areas overflows the digits, the process proceeds to step S48.

In step S47, the CPU 110 records the product in the in-store sales. Specifically, the CPU 110 adds the number to the divided memory areas 140A-2-2, and adds the amount derived in step S44 to the divided memory areas 140A-3-2.
In step S48, the CPU 110 warns of an overflow error in the memory area. For example, the CPU 110 displays an error number corresponding to a digit overflow error in the memory area on the display unit 160, and interrupts the addition process. When the addition process is interrupted, the sales registration process is also interrupted.

In step S49, the CPU 110 derives the amount of the product and the amount of consumption tax. Specifically, the CPU 110 derives the consumption tax amount by multiplying the price 133 of the product specified in step S41 by the reduced tax rate. Next, the CPU 110 derives the amount by adding the consumption tax amount to the price 133. If the number is 2 or more in step S27 (see FIG. 7), the consumption tax amount and the amount are each multiplied by the number.
In step S50, the CPU 110 derives and displays the subtotal amount and the tax amount. Specifically, the CPU 110 adds the amount derived in step S49 to the subtotal amount to newly derive the subtotal amount. Next, the CPU 110 adds the consumption tax amount derived in step S49 to the tax amount to newly derive the tax amount.

In step S51, the CPU 110 determines whether or not the memory areas 140A-2-1, 140A-3-1 overflow. Specifically, the CPU 110 has a memory area 140A-2-1 that stores the cumulative number of sales as a reduced tax rate product in the total memory area 140A (see FIG. 5) corresponding to the specified product, and a cumulative sales amount as a reduced tax rate product. With reference to the memory area 140A-3-1 for storing the above, it is determined whether the memory areas 140A-2-1 and 140A-3-1 overflow when the number and the amount derived in step S49 are added. If both of the memory areas 140A-2-1 and 140A-3-1 do not overflow the digits (step S51 → NO), the process proceeds to step S52, and if any of the memory areas overflows the digits, the process proceeds to step S48.
In step S52, the CPU 110 takes the product home and records it as sales. Specifically, the CPU 110 adds the number to the divided memory areas 140A-2-1 and adds the amount derived in step S49 to the divided memory areas 140A-3-1.

In step S53, the CPU 110 derives the amount of goods and the amount of consumption tax. Specifically, the CPU 110 derives the tax rate (standard tax rate, reduced tax rate, or tax-free) with reference to the tax rate category 134 of the product specified in step S41, and multiplies the price 133 by the tax rate to derive the consumption tax amount. Next, the CPU 110 derives the amount by adding the consumption tax amount to the price 133. If the number is 2 or more in step S27 (see FIG. 7), the consumption tax amount and the amount are each multiplied by the number.

In step S54, the CPU 110 derives and displays the subtotal amount and the tax amount. Specifically, the CPU 110 adds the amount derived in step S53 to the subtotal amount to newly derive the subtotal amount. Next, the CPU 110 adds the consumption tax amount derived in step S53 to the tax amount to newly derive the tax amount.

In step S55, the CPU 110 records the product as normal sales. Specifically, the CPU 110 adds the number to the undivided memory area 140A-2, and adds the amount derived in step S53 to the undivided memory area 140A-3.
In step S56, the CPU 110 clears the product number updated in step S22 (see FIG. 7). Next, the CPU 110 clears (sets to 1) the number updated in step S27.

≪Settlement process≫
FIG. 11 is a flowchart of the settlement process executed by the CPU 110 according to the present embodiment. A process in which the CPU 110 as a print control means prints a sales report (see FIG. 12 described later) will be described with reference to FIG.
In step S61, the CPU 110 prints the header of the sales report (see header 321 in FIG. 12 described later).
In step S62, the CPU 110 executes steps S63 to S68 for each product in the product list 130 (see FIG. 4).

In step S63, the CPU 110 proceeds to step S64 if the tax rate classification 134 is “mark / light” (step S63 → mark / light), and proceeds to step S67 if it is not “mark / light” (step S63 → other).
In step S64, the CPU 110 prints the sales of the take-out product (reduced tax rate product). Specifically, the CPU 110 prints the product name 132 (see FIG. 4) followed by "take-out". Next, the CPU 110 has a cumulative number of sales as a reduced tax rate product stored in the divided memory area 140A-2-1 and a cumulative sales as a reduced tax rate product stored in the divided memory area 140A-3-1. Print the amount and.
In step S65, the CPU 110 prints the sales of the in-store food and drink products (standard tax rate products). Specifically, the CPU 110 prints "inside the store" following the product name 132 (see FIG. 4). Next, the CPU 110 has a cumulative number of sales as a standard tax rate product stored in the divided memory area 140A-2-2 and a cumulative sales as a standard tax rate product stored in the divided memory area 140A-3-2. Print the amount and.

In step S66, the CPU 110 adds to the cumulative sales amount excluding tax. Specifically, the CPU 110 adds the cumulative sales amount of the standard tax rate product stored in the memory area 140A-3-2 to the cumulative sales amount of the standard tax rate product stored in the storage unit 120. Next, the CPU 110 adds the cumulative sales amount of the reduced tax rate product stored in the memory area 140A-3-1 to the cumulative sales amount of the reduced tax rate product stored in the storage unit 120. Subsequently, the CPU 110 derives the consumption tax amount from the cumulative number of sales of the standard tax rate product stored in the memory area 140A-2-2 and adds it to the cumulative tax amount of the standard tax rate product stored in the storage unit 120. Further, the CPU 110 derives the consumption tax amount from the cumulative number of sales of the reduced tax rate product stored in the memory area 140A-2-1 and adds it to the cumulative tax amount of the reduced tax rate product stored in the storage unit 120.

In step S67, the CPU 110 prints the sales of the goods (standard tax rate goods, reduced tax rate goods, or tax-exempt goods). Specifically, the CPU 110 prints the product name 132, the cumulative number of sales stored in the undivided memory area 140A-2, and the cumulative sales amount stored in the undivided memory area 140A-3.
In step S68, the CPU 110 adds to the cumulative sales amount excluding tax. Specifically, the CPU 110 stores the cumulative sales amount stored in the memory area 140A-3 in the storage unit 120 according to the tax rate classification 134 of the product, and the cumulative sales of the standard tax rate product, the reduced tax rate product, or the tax exempt product. Add to the amount. Further, if the tax rate classification 134 of the product is "standard" or "reduced", the CPU 110 derives the consumption tax amount from the cumulative number of sales stored in the memory area 140A-2 and stores the standard tax rate in the storage unit 120. Add to the cumulative tax amount of the product or the reduced tax rate product.

In step S69, if the CPU 110 executes steps S63 to S68 for all the products in the product list 130, the CPU 110 proceeds to step S70. If there is an unprocessed product, the process returns to step S63.
In step S70, the CPU 110 prints the cumulative amount of money 322 (see FIG. 12 described later). Specifically, the CPU 110 prints "standard tax rate target total" and prints the cumulative sales amount of the standard tax rate product stored in the storage unit 120. Next, the CPU 110 prints "tax included" and prints the cumulative tax amount of the standard tax rate product stored in the storage unit 120.

Subsequently, the CPU 110 prints "total for reduced tax rate" and prints the cumulative sales amount of the reduced tax rate product stored in the storage unit 120. Next, the CPU 110 prints "tax included" and prints the cumulative tax amount of the reduced tax rate product stored in the storage unit 120.
Subsequently, the CPU 110 prints "tax-exempt total" and prints the cumulative sales amount of the tax-exempt products stored in the storage unit 120. Next, the CPU 110 prints "total" and prints the total value of the cumulative sales amount of the standard tax rate product, the reduced tax rate product, and the tax exempt product stored in the storage unit 120.

The cumulative sales amount and cumulative tax amount of standard tax rate products stored in the storage unit 120 include the sales amount and consumption tax amount of products registered as standard tax rate products among multiple tax rate products in addition to the standard tax rate products. It has been. In addition, the cumulative sales amount and cumulative tax amount of the reduced tax rate products stored in the storage unit 120 include the sales amount and consumption tax amount of the products registered as sales of the reduced tax rate products among the multiple tax rate products in addition to the reduced tax rate products. It is included.

FIG. 12 is a sales report (sales settlement report) 320 printed by the electronic register 100 according to the present embodiment. In order from the top, the header 321 is printed in step S61 (see FIG. 11), the name, quantity, and amount of money are printed for each product in steps S64, S65, and S67, and the cumulative amount of money 322 is printed in step S70.

≪Characteristics of sales processing and settlement processing≫
The electronic register 100 of the above-described embodiment divides the cumulative sales quantity as a standard tax rate product and the cumulative sales quantity as a reduced tax rate product into a memory area having the same size as the conventional cumulative sales quantity for a plurality of tax rate products. Store in the memory area (sub memory area). Further, the electronic register 100 divides the cumulative sales amount as a standard tax rate product and the cumulative sales amount as a reduced tax rate product into each memory area (sub-memory area) obtained by dividing a memory area having the same size as the conventional cumulative sales amount. Remember. By storing the cumulative sales quantity and the cumulative sales amount of the multiple tax rate products in this way, the store sells the multiple tax rate products without increasing the capacity of the sales settlement data 140 (total memory area 140A). You will be able to execute sales registration processing and settlement processing.

When products are registered up to the maximum number of products in the electronic register, when dealing with multiple tax rate products in the conventional electronic register, either sell as a standard tax rate product or sell as a reduced tax rate product. I had to give up selling the product. Even if the storage unit 120 (see FIG. 1) cannot be expanded and the size of the sales settlement data 140 (total memory area 140A) cannot be increased, the electronic register according to the present embodiment can be updated by updating the program 129. It can be changed to 100, and it will be possible to handle multiple tax rate products without changing the hardware.

≪Modification example: Memory area≫
In the above embodiment, the memory areas 140A-2-1 and 140A-2-2 in which the cumulative number of sales of the plurality of tax rate products is stored are the memory areas 140A in which the cumulative number of sales of the standard tax rate products and the reduced tax rate products are stored. -2 is the same size (memory capacity) as the divided memory area (see FIG. 5). In addition, the memory areas 140A-3-1 and 140A-3-2 that store the cumulative sales amount of multiple tax rate products are divided into the memory areas 140A-3 that store the cumulative sales amount of standard tax rate products and reduced tax rate products. It is the same size (memory capacity) as the area. Since the cumulative sales amount is larger than the cumulative sales quantity and the memory area is likely to overflow, the memory area (sub-memory area) of the cumulative sales amount may be divided so as to be large (allocation). May be).

FIG. 13 is a diagram showing a memory layout of the total memory area 140B for storing the sales settlement data 140 according to the modified example of the present embodiment. The memory areas 140A-2-1 to 140A-3-2 (see FIG. 5) are all five-digit decimal numbers, whereas the memory areas 140B-2-1 and 140B-2-1 that store the cumulative number of sales of multiple tax rate products. 140B-2-2 has 4 decimal digits, and the memory areas 140B-3-1 and 140B-3-2, which store the cumulative sales amount of multiple tax rate products, have 6 decimal digits, respectively. By allocating a wider memory area to the cumulative sales amount than the cumulative sales quantity, it is possible to reduce the possibility of overflowing digits.

In order to store a larger numerical value in a memory area of the same size, it may be stored in binary format instead of BCD format. Since the memory areas 140A-2-1 to 140A-3-2 are each 2.5 bytes, they may be stored in the form of 2.5 bytes (20 bits) of unsigned binary integers.

≪Modification example: Memory setting process≫
In the above embodiment, the memory setting 135 is set by the tax rate setting process (FIG. 6), but the memory setting 135 is set by scanning the preset tax rate category 134. May be good.

FIG. 14 is a flowchart of the memory setting process executed by the CPU 110 according to the modified example of the present embodiment.
In step S81, the CPU 110 scans the tax rate classification 134 of all products in the product list 130 (see FIG. 4).
In step S82, the CPU 110 as the switching means determines whether or not there is a product for which the tax rate category 134 is set to "mark / light". When it is determined that there is no product for which the tax rate category 134 is set to "mark / light" (step S82 → NO), the CPU 110 proceeds to step S83, and when it is determined that the product exists (step S82 → YES). The CPU 110 proceeds to step S85.
In step S83, the CPU 110 as the switching means sets a single tax rate mode (second sales mode) as the sales mode.
In step S84, the CPU 110 as the dividing means sets the memory setting 135 to "non-divided" for all the products in the product list 130.

In step S85, the CPU 110 as the switching means sets a plurality of tax rate modes (first sales mode) as the sales mode.
In step S86, the CPU 110 as the division means sets the memory setting 135 to "division" for the predetermined product in the product list 130. The product in which the memory setting 135 is set to "split" may be, for example, a product in which the tax rate category 134 is set to "mark / light". However, the present invention is not limited to this, and for example, the memory setting 135 may be set to "divided" for all the products in the product list 130.

Further, in the memory setting process of FIG. 14, only the memory setting 135 is set based on the sales mode setting, but the target of the setting is not limited to the memory setting 135, and the display setting and printing are performed. The setting, the operation setting, and the like may be set based on the sales mode.

≪Modification example: Inspection by product≫
In the settlement process (see FIG. 11), for example, the cumulative sales amount for each product for one day is totaled and the sales report is printed. The cumulative sales quantity and cumulative sales amount of the specified product may be output by a specific operation. For example, after the mode switch 179 is set to "inspection", when the product number is input by the numeric keypad 171 and the PLU key 172 is pressed, the CPU 110 performs the cumulative sales stored in the memory area 140A-2 of the corresponding product. The number and the cumulative sales amount stored in the memory area 140A-3 are displayed on the display unit 160. If the product is a product with multiple tax rates, the CPU 110 will add the cumulative sales quantity stored in the divided memory areas 140A-2-1 and 140A-2-2 to the cumulative sales quantity and the divided memory area 140A-. The cumulative sales amount, which is the sum of the cumulative sales amounts stored in 3-1 and 140A-3-2, is displayed.

For multiple tax rate products, when the product number is entered with the numeric keypad 171 and the take-out key 173 is pressed, the CPU 110 stores the cumulative number of units sold as the reduced tax rate applied product stored in the memory area 140A-2-1 of the corresponding product. And the cumulative sales amount as the reduced tax rate applied product stored in the memory area 140A-3-1 may be displayed on the display unit 160. Further, when the product number is input by the ten key 171 and the in-store key 174 is pressed, the CPU 110 stores the cumulative number of sales as a standard tax rate applied product and the memory area 140A stored in the memory area 140A-2-2 of the corresponding product. The cumulative sales amount of the standard tax rate applied product stored in -3-2 may be displayed on the display unit 160.

≪Modification example: Inspection of all products≫
In the above modification, the cumulative sales amount of the specified product is displayed. The cumulative sales amount of all products may be displayed. For example, if the x key 177 is pressed after the mode switch 179 is set to "inspection", the CPU 110 may display the cumulative sales amount of all products. In order to derive the cumulative sales amount of all products, a settlement process (see FIG. 11) that does not include printing may be executed.

≪Other variants≫
In the above-described embodiment, each product is registered in the sales registration. Specifically, the product number is entered with the numeric keypad 171 and then the PLU key 172 is pressed to register the product (see FIG. 7). The product may be registered as sales for each product division, and the sales registration report may also be printed for each product division. Specifically, a product in a certain product department may be a product with a plurality of tax rates, and it may be registered at the time of sales registration whether it is a take-out product or an in-store product, and the standard tax rate and the reduced tax rate are distinguished and the sales are registered. The flow of the sales registration process is the same as that of the above-described embodiment except for the difference between the product number and the product department number.

In the above embodiment, the memory setting 135 is set to "split" or "non-split" prior to the sales registration process, but the memory setting 135 is set based on the timing when the product is specified in the sales registration process. You may do it. Specifically, after the product is specified in step S41 of FIG. 10, it is determined whether or not "mark / light" is set in the tax rate category 134 of the product, and "mark / light" is set in the tax rate category 134. If it is set, "split" may be set in the memory setting 135, while if the tax rate classification 134 is set to something other than "mark / light", the memory setting 135 may be set to "non-split".
In addition, as the timing for setting the memory setting 135, for example, in the sales registration process, the timing when one product is registered as sales in two sales modes (the timing when sales are registered as both a take-out product and an in-store food and drink product). ) May be. That is, the memory setting 135 may be set at a predetermined timing, and is not particularly limited.
