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

  The law related to tax reform in 2015 was passed at the House of Councilors' Meeting on March 31, 2015, and was enacted. This law will raise the consumption tax rate to 10% in April 2017. A reduced tax rate system will also be introduced as a measure against low-income earners accompanying the 10% increase in the consumption tax rate.

  The reduced tax rate system introduced this time is a system that keeps the consumption tax rate at 8% for some products that have a large impact on low-income earners. Items subject to the reduced tax rate system are transfer of food and beverages and subscription fees for newspapers issued at least twice a week. However, in the transfer of food and beverage products, the provision of meals by business operators operating restaurants and restaurants in places with certain food and beverage facilities is excluded from the items subject to the reduced tax rate system. In other words, the standard tax rate applies to food and beverage items that are eaten out.

  Specifically, examples of where the reduced tax rate is applied without eating out include take-out of beef bowls and hamburgers, delivery of soba noodles, delivery to pizzerias, snacks at stalls, sushi and souvenirs, Convenience store lunches and side dishes are listed. In addition, examples where the standard tax rate is applied for eating out are provided on the premise of eating and drinking at beef restaurant, hamburger shop, soba restaurant, pizza shop and sushi restaurant, snacks at food court, eating and drinking at convenience store eat-in corner Food and drinks, catering and business trips are listed.

  The provision of meals under the reduced tax rate system is classified as eating out if it is performed at a place where a business such as a restaurant business under the Food Sanitation Act has installed facilities for eating and drinking on the spot. In addition, cooking at a place designated according to the order of the other party is also classified as a restaurant here.

  As an invention corresponding to such a plurality of tax rates, there is an invention described in Patent Document 1, for example. As a means for solving the abstract of Patent Document 1, “In ECR1, a packed product including a plurality of taxable products is subjected to a tax amount calculation method set in advance in the TAX table setting memory 54 by a single product registration process. The tax amount of each taxable product is calculated, and the taxable amount can be printed on the receipt for each taxable product. "

When “external tax (standard tax rate)” or “external tax (reduced tax rate)” is stored in the calculation method column, the unit price before tax is stored in the unit price column. In the tax rate column, the tax rate corresponding to the product is stored in percentage units.

FIG. 5 is a diagram illustrating the configuration of the input unit 18 of the electronic cash register 1.
The input unit 18 includes a group of keys arranged in a matrix of 7 rows and 6 columns, and these key groups are divided into approximately four groups. Keys used for merchandise registration are mainly arranged in the lower left section and the lower right section. Here, the lower left section and the lower right section of the key group will be described, and the description of the upper left section and the upper right section will be partially omitted.

The “C” (clear) key belonging to the lower left section is used when the operator makes an input error. The “x / date and time” key is used for multiplication registration and is used for displaying time and date. The “10,000 yen” key is used when a 10,000 yen bill is deposited.
Numeric keys such as “9” to “0”, “00”, “•” are used for inputting numerical values.

  The “department 1” key to the “department 5” key belonging to the lower right section are used when an operator registers a product. The “subtotal” key is used when viewing the total of registered amounts (intermediate total). The “current / deposit” key is used for completion of registration and deposit.

  In addition, the “deposit” key is used when depositing. The “withdrawal” key is used at the time of withdrawal, and also at the time of issuing an electronic journal report. The “−” key is used for discounting, and the “%” key is used for discounting. The “trust” (credit sales) key is used when selling a credit card, and the “ticket” (ticket sales) key is used when selling with a gift certificate. The “# / alternate” key is used for number printing or currency exchange. The “PLU” key is used when a product is designated by a PLU number.

FIG. 6 is a flowchart showing the product registration process.
The CPU 11 of the electronic cash register 1 repeats the processes of steps S10 to S23 for each transaction with the customer. Display examples of the display unit 14 and the customer display unit 15 at this time are shown in FIGS. Moreover, every time an operator registers a product, the CPU 11 repeats the processes of steps S10 to S17.
The CPU 11 determines which key of the input unit 18 has been input (step S10).

In step S10, if the numeric key of the input unit 18 is pressed, the CPU 11 updates the numbers in the display unit 14 and the customer display unit 15 (step S11), and returns to the process in step S10.
If the “x” key is pressed in step S10, the CPU 11 proceeds to step S12 in which the numbers on the display unit 14 and the customer display unit 15 are determined as the product quantity, and returns to the process in step S10. More specifically, when the operator inputs the product quantity, the operator may input the product quantity using the numeric keys and then press the “x” key.

If the “department 1” key is pressed in step S10, the CPU 11 proceeds to step S13 to determine the numbers of the display unit 14 and the customer display unit 15 as the standard tax rate and the internal tax system, and the “department 2” key. If is pressed, the process proceeds to step S14 where the numbers on the display unit 14 and the customer display unit 15 are determined as the reduced tax rate and the internal tax system, and the process returns to step S10.
More specifically, when the operator inputs a product price with a numeric key and then presses the “Department 1” key, the price of the product at the standard tax rate is input by the internal tax method. Further, when the operator inputs the product price with the numeric keys and then presses the “department 2” key, the price of the product with the reduced tax rate is input by the internal tax method.

In step S10, if the “department 3” key is pressed, the CPU 11 determines the numbers on the display unit 14 and the customer display unit 15 as the standard tax rate and the external tax system (step S15), and the “department 4” key. Is pressed, the numbers on the display unit 14 and the customer display unit 15 are determined as the reduced tax rate and the external tax system (step S16), and the process returns to step S10.
More specifically, when the operator inputs the price of the commodity at the standard tax rate by the external tax method, it is preferable to press the “department 3” key after inputting the commodity price with the numeric keys. Further, when the operator inputs the price of the reduced tax rate product by the external tax method, it is preferable to press the “Department 4” key after inputting the product price with the numeric keys.
If the “PLU” key is pressed in step S10, the CPU 11 proceeds to step S17 to determine the product, unit price, tax rate, and calculation method using the numbers on the display unit 14 and the customer display unit 15 as PLU numbers. Thereafter, the process returns to step S10. More specifically, when a product is designated by the PLU number, the operator may input the PLU number with a numeric key and then press the “PLU” key.

In step S10, if the “subtotal” key is pressed, the CPU 11 calculates a subtotal and a difference (step S18). Here, the difference is the difference between the standard tax amount and the reduced tax amount. That is, if the product or service for which the sales registration has been received is a product to which the reduced tax rate (first tax rate) is applied, the CPU 11 The difference between the tax-included price and the tax amount or tax-included price when the standard tax rate (second tax rate) is applied to this product or this service is derived. That is, if the product for which the sales registration has been received is a product to which the reduced tax rate (first tax rate) is applied, the CPU 11 determines the tax amount when the reduced tax rate is applied to this product and the standard for this product. A difference from the tax amount when the tax rate (second tax rate) is applied is derived, and the derived difference is output to the display unit 14 and the customer display unit 15.
The CPU 11 determines which key of the input unit 18 is input while alternately displaying the subtotal and the difference on the display unit 14 and the customer display unit 15 (step S19). If the number key is pressed, the CPU 11 updates the numbers on the display unit 14 and the customer display unit 15 (step S21), and returns to the process of step S20.
In step S20, if the “cash / deposit” key is pressed, the CPU 11 calculates and displays the change (step S22), causes the printing unit 16 to print a receipt (step S23), and performs the processing of FIG. finish. A print example of the receipt at this time is shown in FIGS. 8, 9, and 11 to be described later.

FIGS. 7A to 7E are diagrams showing display examples of accounting in the case of the internal tax system. In the display examples of FIGS. 7A to 7E, the operator inputs an item of 2200 yen to which the standard tax rate is applied and an item of 1080 yen to which the reduced tax rate is applied, and displays a subtotal. This is an example when a deposit of 4000 yen was received later.

When registering this product, the electronic cash register 3 pulls out a drawer (not shown) and deposits a deposit. The product registration is not limited to PLU input, and product information may be read by a barcode reader, or buttons corresponding to each product may be displayed on the touch panel display 34.

FIG. 15 is a block diagram showing a configuration of the electronic cash register 3.
In FIG. 15, the electronic cash register 3 includes a CPU 31, a RAM 32, a ROM 33, a touch panel display 34, a customer display unit 35, a printing unit 36, an external interface 37, an input unit 38, and a storage unit 39. Connected by.

  The CPU 31 stores, in the RAM 32, application programs specified from various application programs corresponding to the electronic cash register 3 stored in the ROM 33 and the storage unit 39 and various instructions input from the touch panel display 34 and the input unit 38. Expand to the working memory. Further, the CPU 31 executes various processes in accordance with the application program developed in the work memory in accordance with the input instruction and the input data, stores the processing results in the work memory in the RAM 32, and displays the touch panel display 34 and the customer display unit 35. To display. Then, the processing result stored in the work memory is stored in the storage destination in the storage unit 19 instructed from the touch panel display 34 or the input unit 38.

  In addition, the CPU 31 analyzes the instruction content input from the touch panel display 34 in a product registration process (see FIG. 17) to be described later. If the instruction content is PLU designation, the PLU file 391 stored in the storage unit 19 is analyzed. Is registered, the product related to the corresponding PLU is registered, and the tax amount of this product is calculated. Then, the CPU 31 analyzes the instruction content input from the touch panel display 34 in the entire process, and executes the tightening process when the instruction content is tightening, or performs processing according to other instruction content.

The input unit 38 is, for example, a power switch or a reset switch, and outputs a pressing signal indicating that these switches have been pressed to the CPU 31.
The touch panel display 34 is formed by laminating a transparent touch panel on the surface of a display device such as a liquid crystal display, and has both a display function and an input function. This touch panel (touch screen) senses coordinates designated by an input pen, fingertip, etc., detects position coordinates designated by a coordinate reading principle such as an electromagnetic dielectric method, a magnetostrictive method, and a pressure sensitive method, and outputs them to the CPU 31. To do. The CPU 31 displays various keys on a display device that constitutes the touch panel display 34, and detects that the display area of these keys has been tapped with the touch panel. Thus, the CPU 31 embodies functions such as a numeric key, a “PLU” key, and a “subtotal” key, and accepts sales registration of goods or services. Further, the CPU 31 derives a tax amount or a tax-inclusive price based on a predetermined tax rate for the product or service for which the sales registration is accepted, and outputs the tax amount or the tax-inclusive price on the touch panel display 34.
The “x” key embodied on the touch panel display 34 is used for multiplication registration and is used for displaying time and date. Numeric keys such as “9” to “0”, “00”, “•” are used for inputting numerical values. The “subtotal” key is used when viewing the total of registered amounts (intermediate total). The “current / deposit” key is used for completion of registration and deposit. The “PLU” key is used when a product is designated by a PLU number.

The customer display unit 35 is configured by a liquid crystal display, an organic EL display, or the like, and supports kanji / hiragana / katakana display. The CPU 31 derives a tax amount or a tax-inclusive price based on a predetermined tax rate for the product or service for which the sales registration is accepted, and outputs the tax amount or the tax-inclusive price on the customer display unit 35.
The printing unit 36 is, for example, a thermal transfer printer, and prints and outputs receipt information on roll paper (receipt paper). In accordance with the instruction from the CPU 31, the printing unit 36 is configured to apply the tax amount of the applicable product or application service of the reduced tax rate and the standard tax rate applied to the applicable product or application service based on the price and tax rate of the product or service. The difference from the tax amount is output on the receipt.
The external interface 37 is for connecting a drawer 41, a barcode scanner 42, and the like, for example.
The drawer 41 is a part that stores cash and can be pulled out by the operator operating the electronic cash register 3. The barcode scanner 42 is a part that reads a barcode of a product by an operator's operation.

The storage unit 39 is configured by a rewritable storage medium such as a magnetic or optical storage medium or a semiconductor memory. In addition to the PLU file 391, the storage unit 39 stores system programs, various application programs corresponding to the system, data processed by these programs, and the like. The PLU file 391 will be described in detail with reference to FIG.
The CPU 31 refers to the PLU file 391 to determine which of the reduced tax rate and the standard tax rate is applied to each product or each service.

  A part or all of the programs, data, and the like stored in the storage unit 39 may be received from other devices such as a server and a client via a transmission medium such as a network line and stored. Further, the storage unit 39 may be a server recording medium built on a network. Furthermore, each program may be configured to be transmitted to a server or a client via a transmission medium such as a network line and installed in these devices.

FIG. 16 is a diagram for explaining the PLU file 391.
Similar to the PLU file 192 (see FIG. 4) of the first embodiment, the PLU file 391 includes a PLU number column, a product name column, a unit price column, a calculation method column, and a tax rate column. Thereby, the correspondence between the PLU number and the product / unit price / calculation method / tax rate can be shown.
The PLU number column stores a product code related to the product. In the product name column, the product name related to the product is stored. The unit price column stores the unit price in the tax calculation method applied to the product. The calculation method column stores the calculation method of the tax amount applied to the product. For example, when “tax (standard tax rate)” or “tax (reduced tax rate)” is stored in the calculation method column, the tax-included unit price is stored in the unit price column. When “external tax (standard tax rate)” or “external tax (reduced tax rate)” is stored in the calculation method column, the unit price before tax is stored in the unit price column. In the tax rate column, the tax rate corresponding to the product is stored in percentage units.

FIG. 17 is a flowchart showing the product registration process.
CPU31 of the electronic cash register 3 repeats the process of step S30-S39 for every transaction with a customer. Moreover, every time an operator registers a product, the CPU 31 repeats the processes of steps S30 to S33.
The CPU 31 determines which of the keys displayed on the touch panel display 34 has been input (step S30).

In step S30, if the number key on the touch panel display 34 is tapped, the CPU 31 updates the numbers on the touch panel display 34 or the customer display unit 35 (step S31), and returns to the process of step S30.
If the “x” key on the touch panel display 34 is tapped in step S30, the CPU 11 proceeds to step S32 in which the numbers on the touch panel display 34 and the customer display unit 35 are determined as the product quantity, and the process of step S30 is performed. Return. Specifically, when the operator inputs the product quantity, the operator may tap the numeric key on the touch panel display 34 to input the product quantity and then tap the “x” key.

  If the “PLU” key on the touch panel display 34 is tapped in step S30, the CPU 31 determines a product, a unit price, and a tax rate using the numbers on the touch panel display 34 and the customer display unit 35 as PLU numbers. Then, the process returns to step S30. More specifically, when a product is designated by the PLU number, the operator may input the PLU number with the numeric keys on the touch panel display 34 and then tap the “PLU” key.

  In step S30, if the “subtotal” key on the touch panel display 34 is tapped, the CPU 31 calculates the subtotal and the difference (step S34). Here, the difference is the difference between the standard tax amount and the reduced tax amount. The CPU 31 displays the subtotal and the difference on the touch panel display 34 and the customer display unit 15 (step S35). That is, if the product for which the sales registration has been received is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 uses the tax amount when the reduced tax rate is applied to this product and the standard for this product. A difference from the tax amount when the tax rate (second tax rate) is applied is derived, and the derived difference is output to the touch panel display 34 and the customer display unit 35.

Further, when the product for which the sales registration has been received is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 outputs the difference as the reduction information, and the product for which the sales registration has been received is the standard tax rate ( In the case of a product to which the second tax rate is applied, this difference is output to the touch panel display 34 or the customer display unit 15 as increase information.
If the numeric key on the touch panel display 34 is tapped (step S36), the CPU 11 updates the numbers on the touch panel display 34 and the customer display unit 15 (step S37), and returns to the process of step S36.
In step S36, if the “current / deposit” key on the touch panel display 34 is tapped, the CPU 11 calculates and displays the change (step S38), and causes the printing unit 36 to print a receipt (step S39). The process of FIG. 17 is terminated.
