Description

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

The 2015 tax reform-related law was passed and passed at the House of Councilors plenary session on March 31, 2015. According to this law, the consumption tax rate will be raised to 10% in April 2017. A reduced tax rate system will also be introduced as a measure for low-income earners following 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 the transfer of food and drink and the subscription fee for newspapers issued at least twice a week. However, among the transfers of food and drink, the provision of meals provided by businesses operating restaurants, etc. in places with certain eating and drinking facilities is excluded from the items subject to the reduced tax rate system. In other words, the standard tax rate is applied to the transfer of food and drink that corresponds to eating out.

Specifically, examples where the reduced tax rate is applied without eating out include take-out at gyudon restaurants and hamburger restaurants, delivery at soba restaurants, home delivery at pizza restaurants, light meals at food stalls, sushi and souvenirs, etc. Convenience store lunch boxes and side dishes are listed. In addition, examples where the standard tax rate is applied when eating out are provided on the premise of eating and drinking in the gyudon shop, hamburger shop, soba shop, pizza shop and sushi shop, light meal at the food court, eating and drinking at the eat-in corner of the convenience store. Food and drink, catering and business trip dishes are listed.

Under the reduced tax rate system, meals are classified as eating out if they are provided at a place where a business operator such as a restaurant business under the Food Sanitation Law has installed equipment for eating and drinking on the spot. Also, cooking at a designated place according to the order of the other party is also classified as eating out here.

Inventions corresponding to such a plurality of tax rates include, for example, the invention described in Patent Document 1. As a means for solving the abstract of Patent Document 1, "In ECR1, a tax amount calculation method set in advance in the TAX table setting memory 54 is performed by one product registration process for a pack product containing a plurality of taxable products. , The tax amount of each taxable product was calculated, and the taxable amount could be printed on the receipt for each taxable product. "

Japanese Unexamined Patent Publication No. 2003-256937

However, in the invention described in Patent Document 1, the difference from the standard tax rate under the reduced tax rate system had to be calculated by the customer by mental arithmetic or the like.
For example, if an item with a standard tax rate is registered as an internal tax of 2200 yen and an item with a reduced tax rate is registered as an internal tax of 2160 yen, the difference from the standard tax rate under the reduced tax rate system is 40 yen. However, this could not be read directly from the receipt or the display on the display. Therefore, each customer could not easily realize the merits of the reduced tax rate system.

Further, 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. 3 is a diagram illustrating a department table 191.
The department table 191 includes a department code column, a department name column, a calculation method column, and a tax rate column. This shows the correspondence between each department key and the tax calculation method.
Department 1 is the department in which the amount of the tax-included method is input for the item to which the standard tax rate of 10% is applied. Here, the tax-included method refers to a method of selling a product in which the consumption tax is included in the product price. When the user selects the department 1 key, "department 01" in the department name column is displayed on the display unit 14, and the tax amount and the tax amount are displayed at the "tax included" described in the calculation method column and the tax rate of 10% described in the tax rate column. The tax-included price is calculated.
The department 2 is a department in which the amount of the tax-included method is input for the item to which the reduced tax rate of 8% is applied. When the user selects the department 2 key, "department 02" in the department name column is displayed on the display unit 14, and the tax amount and the tax amount are displayed at the "tax included" described in the calculation method column and the tax rate of 8% described in the tax rate column. The tax-included price is calculated.
The department 3 is a department in which the amount of the tax-excluded method is input for the item to which the standard tax rate of 10% is applied. Here, the tax-excluded method refers to a method of selling products whose consumption tax is not included in the product price. When the user selects the department 3 key, "department 03" in the department name column is displayed on the display unit 14, and the tax amount and the tax amount are displayed at the "excluding tax" described in the calculation method column and the tax rate of 10% described in the tax rate column. The tax-included price is calculated.
The department 4 is a department in which the amount of the tax-excluded method is input for the item to which the reduced tax rate of 8% is applied. When the user selects the department 4 key, "department 04" in the department name column is displayed on the display unit 14, and the tax amount and the tax amount are displayed at the "excluding tax" described in the calculation method column and the 8% tax rate described in the tax rate column. The tax-included price is calculated.

FIG. 4 is a diagram illustrating a PLU file 192.
The PLU file 192 includes a PLU number column, a product name column, a unit price column, a calculation method column, and a tax rate column. This makes it possible to indicate the correspondence between the PLU number and the product, unit price, calculation method, and tax rate.
The product code related to the product is stored in the PLU number column. The product name related to the product is stored in the product name column. In the unit price column, the unit price in the tax calculation method applied to the product is stored. The calculation method column stores the calculation method of the tax amount applied to the product. For example, when "tax included (standard tax rate)" or "tax included (reduced tax rate)" is stored in the calculation method column, the unit price including tax is stored in the unit price column. When "excluding tax (standard tax rate)" or "excluding tax (reduced tax rate)" is stored in the calculation method column, the unit price excluding 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 showing a configuration of an input unit 18 of the electronic cache 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 roughly divided into four. The keys used for product 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 explanation 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 erroneous input. The "x / date and time" key is used for multiplication registration and for displaying the time and date. The "10,000 yen" key is used when depositing a 10,000 yen bill.
Numeric keys such as "9" to "0", "00", and "・" are used for inputting numerical values.

The "Department 1" to "Department 5" keys belonging to the lower right section are used when the operator registers the product. The "subtotal" key is used to see the total registered amount (interim total). The "Current / Deposit" key is used to complete registration and deposit.

In addition, the "deposit" key is used at the time of deposit. The "Withdrawal" key is used not only when withdrawing money, but also when issuing an electronic journal report. The "-" key is used for discounts and the "%" key is used for discounts. The "credit" (credit selling) key is used when selling a credit card, and the "ticket" (ticket selling) key is used when selling a gift certificate. The "# / exchange" key is used when printing numbers or exchanging money. The "PLU" key is used to specify the product by 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. 7 and 8 described later. Further, every time the operator registers the 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, when the number key in 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 for determining the numbers of the display unit 14 and the customer display unit 15 as the product quantity, and returns to the process of step S10. Specifically, when the operator inputs the product quantity, it is preferable to press the "x" key after inputting the product quantity with the number keys.

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 tax-included method, and proceeds to the "department 2" key. When is pressed, the process proceeds to step S14 for determining the numbers on the display unit 14 and the customer display unit 15 as the reduced tax rate and the tax-included method, and returns to the process of step S10.
Specifically, when the operator inputs the product price with the number keys and then presses the "department 1" key, the price of the product at the standard tax rate is input by the tax-included method. Further, when the operator presses the "department 2" key after inputting the product price with the numerical keys, the price of the product with the reduced tax rate is input by the tax-included method.

In step S10, if the "department 3" key is pressed, the CPU 11 determines the numbers of the display unit 14 and the customer display unit 15 as the standard tax rate and the tax exemption method (step S15), and the "department 4" key. When is pressed, the numbers of the display unit 14 and the customer display unit 15 are determined as the reduced tax rate and the tax exemption method (step S16), and the process returns to the process of step S10.
Specifically, when the operator inputs the price of the product at the standard tax rate by the tax-excluded method, it is preferable to input the product price with the number keys and then press the "department 3" key. Further, when the operator inputs the price of the product with the reduced tax rate by the tax-excluded method, it is preferable to input the product price with the number keys and then press the "department 4" key.
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 in the display unit 14 and the customer display unit 15 as the PLU number. After that, the process returns to the process of step S10. Specifically, when the operator specifies a product by the PLU number, it is preferable to press the "PLU" key after inputting the PLU number with the number keys.

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

7 (a) to 7 (e) are diagrams showing an example of accounting presentation in the case of the tax-included method. In these 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 the subtotal. This is an example when a deposit of 4000 yen is received later.
FIG. 7A shows a display example of the display unit 14 and the customer display unit 15 when the operator sequentially presses “2”, “2”, “0”, “0”, and “department 1”. There is.

FIG. 7E shows a display example of the display unit 14 and the customer display unit 15 when the operator sequentially presses “4”, “0”, “0”, “0”, and “current / deposit”. ing.
"Change" is displayed on the first line of the display unit 14, and the change amount "720" is displayed on the second line. The change amount "720" is displayed on the customer display unit 15. This allows the operator to easily see that the change is 720 yen.

FIG. 8A is a diagram showing a first printing example of the receipt in the case of the tax-included method.
The receipt 2a is composed of a title column 21, a date and time column 22, a plurality of item columns 23a and 23b, a total column 24, a deposit column 25, and a change column 26 printed on the roll paper.
The title column 21 is printed as "calculation form", and the date and time column 22 is printed with the date and time of accounting. Below that, item columns 23a and 23b including the department and amount, "10% tax included" and the amount of consumption tax are printed. Further, the total amount of money "¥ 3,280" is printed in the total column 24. This total amount is the amount after reduction.
The deposit amount "4,000 yen" is printed in the deposit column 25, and the change amount "720 yen" to be returned to the customer is printed in the change column 26.

The receipt 2a is further printed with a reduction column 27 and a difference column 28.
In the column 27 before reduction, the amount before reduction "¥ 3,300" with all items as the standard tax rate is printed.

Display on. Then, the processing result stored in the work memory is saved in the storage destination in the storage unit 19 instructed by the touch panel display 34 or the input unit 38.

Further, the CPU 31 analyzes the instruction content input from the touch panel display 34 in the product registration process (see FIG. 17) described later, and if the instruction content is a PLU designation, the PLU file 391 stored in the storage unit 19 Search for, register the product related to the corresponding PLU, and calculate the tax amount of this product. Then, the CPU 31 analyzes the instruction content input from the touch panel display 34 in the overall processing, and if the instruction content is tightening, executes the tightening process, or executes a process according to another instruction content.

The input unit 38 is, for example, a power switch, a reset switch, or the like, and outputs a pressing signal when these switches are pressed to the CPU 31.
The touch panel display 34 has a transparent touch panel laminated 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 the coordinates specified by the input pen, fingertips, etc., detects the position coordinates specified by the coordinate reading principle such as electromagnetic dielectric method, magnetostriction type, pressure sensitive type, etc., and outputs it to the CPU 31. To do. The CPU 31 displays various keys and the like on the display device constituting the touch panel display 34, and detects on the touch panel that the display area of these keys has been tapped. As a result, the CPU 31 embodies functions such as a number key, a "PLU" key, and a "subtotal" key, and accepts sales registration of a product or service. Further, the CPU 31 derives a tax amount or a tax-included price based on a predetermined tax rate for the product or service that has received the sales registration, and outputs the tax amount or the tax-included price on the touch panel display 34.
The "x" key embodied on the touch panel display 34 is used for multiplication registration and for displaying the time and date. Numeric keys such as "9" to "0", "00", and "・" are used for inputting numerical values. The "subtotal" key is used to see the total registered amount (interim total). The "Current / Deposit" key is used to complete registration and deposit. The "PLU" key is used to specify the product by PLU number.

The customer display unit 35 is composed of a liquid crystal display, an organic EL display, or the like, and supports kanji, hiragana, and katakana display. The CPU 31 derives a tax amount or a tax-included price based on a predetermined tax rate for the product or service that has received the sales registration, and outputs the tax amount or the tax-included 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). The printing unit 36 determines that the tax amount of the applicable product or service of the reduced tax rate and the standard tax rate are applied to the applicable product or service based on the price and tax rate of the product or service according to the instruction of the CPU 31. Output the difference from the tax amount on the receipt.

The drawer 41 is a portion for storing cash, and can be withdrawn by the operator operating the electronic cash register 3. The bar code scanner 42 is a portion that reads a bar code of a product by an operator's operation.

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

Further, the program, data, etc. to be stored in the storage unit 39 may be configured to receive and store a part or all of the program, data, etc. from another device such as a server or a client via a transmission medium such as a network line. Further, the storage unit 39 may be a recording medium of a server constructed on the network. Further, 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 illustrating a PLU file 391.
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, similarly to the PLU file 192 (see FIG. 4) of the first embodiment. This makes it possible to indicate the correspondence between the PLU number and the product, unit price, calculation method, and tax rate.
The product code related to the product is stored in the PLU number column. The product name related to the product is stored in the product name column. In the unit price column, the unit price in the tax calculation method applied to the product is stored. The calculation method column stores the calculation method of the tax amount applied to the product. For example, when "tax included (standard tax rate)" or "tax included (reduced tax rate)" is stored in the calculation method column, the unit price including tax is stored in the unit price column. When "excluding tax (standard tax rate)" or "excluding tax (reduced tax rate)" is stored in the calculation method column, the unit price excluding 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.
The CPU 31 of the electronic cash register 3 repeats the processes of steps S30 to S39 for each transaction with the customer. Further, every time the operator registers the 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, when the number keys on the touch panel display 34 are tapped, the CPU 31 updates the numbers on the touch panel display 34 and 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 for determining the number of the touch panel display 34 or the customer display unit 35 as the product quantity, and proceeds to the process of step S30. go back. Specifically, when the operator inputs the product quantity, it is preferable to tap the number keys on the touch panel display 34, 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 the product, the unit price, and the tax rate using the numbers on the touch panel display 34 and the customer display unit 35 as the PLU number. Then, the process returns to the process of step S30. Specifically, when the operator specifies a product by the PLU number, it is preferable to input the PLU number with the number keys on the touch panel display 34 and then tap the "PLU" key.

In step S30, the CPU 31 calculates the subtotal and the difference if the "subtotal" key on the touch panel display 34 is tapped (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, when the product for which sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 sets the tax amount when the reduced tax rate is applied to this product and the standard for this product. The 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.

Furthermore, if the product for which sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 outputs this difference as reduction information, and the product for which sales registration has been accepted is the standard tax rate (first tax rate). If the product is to which the second tax rate) is applied, the difference is output to the touch panel display 34 or the customer display unit 15 as increase information.
If the number keys on the touch panel display 34 are 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, when the "current / deposit" key on the touch panel display 34 is tapped, the CPU 11 calculates and displays the change (step S38), causes the printing unit 36 to print the receipt (step S39), and causes the printing unit 36 to print the receipt. The process of FIG. 17 is terminated.
