Description

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

The tax reform related law of 2015 was approved and passed at the plenary session of the House of Councilors on March 31, 2015. Under 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 with 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. The items subject to the reduced tax rate system are the transfer of food and beverages and the subscription fee for newspapers issued twice or more a week. However, among transfers of food and drink, provision of meals by businesses engaged in restaurant business, etc. at 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 food and beverages that are eaten out.

Specifically, examples of reduced tax rates that apply to eating out are not limited to eating out, such as takeout at beef bowl restaurants and hamburgers, delivery of soba restaurants, delivery at pizzerias, snacks at stalls, sushi and souvenirs, Bento and side dishes of convenience stores are listed. In addition, examples of standard tax rates applied to eating out are provided on the premise of eating and drinking at beef bowl restaurants, hamburgers, soba restaurants, pizzerias, and sushi restaurants, light meals at food courts, and eating and drinking at convenience store eat-in corners. Food and beverages, catering and business trip meals are listed.

Provision of meals under the reduced tax rate system is classified as eating out if it is done at a place where a business operator such as a restaurant business under the Food Sanitation Law installs facilities for eating and drinking on the spot. Cooking at a designated place according to the order of the other party is also classified as eating out here.

An invention corresponding to such a plurality of tax rates is, for example, an invention described in Patent Document 1. According to the solution of the abstract in Patent Document 1, "In ECR1, according to a tax amount calculation method preset in the TAX table setting memory 54 by one-time product registration processing for a pack product including a plurality of taxable products. , The tax amount of each taxable product is calculated, and the taxable amount can be printed on the receipt for each taxable product.”

The unit price column stores the unit price according to the tax calculation method for the product. The calculation method column stores the calculation method of the tax amount for the product. For example, when “internal tax (standard tax rate)” or “internal 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 without tax is stored in the unit price column. The tax rate column stores the tax rate corresponding to the product in percent.

FIG. 5 is a diagram showing a configuration of the input unit 18 of the electronic cash register 1.
The input unit 18 includes a key group arranged in a matrix of 7 rows and 6 columns, and these key groups are divided into approximately four groups. 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 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" key is used for multiplication registration and also for displaying time and date. The "10,000 yen" key is used when depositing a 10,000 yen bill.
Numerical keys such as “9” to “0”, “00”, “·” are used for inputting numerical values.

The “Department 1” to “Department 5” keys belonging to the lower right section are used by the operator when registering products. The "subtotal" key is used to see the total (intermediate total) of registered amounts for each tax rate. The "cash/deposit" key is used at the time of registration completion and deposit. Further, the "total" key is used to view the total (intermediate total) of the registered amounts of sales.

In addition, the "payment" key is used when depositing money. The “withdrawal” key is used not only when withdrawing money but also when issuing an electronic journal report. The "-" key is used for discounting, and the "%" key is used for discounting. The "credit" (credit selling) key is used when selling credit cards, and the "ticket" (ticket selling) key is used when selling with gift certificates. The "PLU" key is used when designating a product by the PLU number.

FIG. 6 is a flowchart showing the product registration process.
The CPU 11 of the electronic cash register 1 repeats the processing of steps S10 to S22 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. Also, every time the operator registers a product, the CPU 11 repeats the processing of steps S10 to S18. In this flow chart, the processing when the "cash/deposit" key is pressed is omitted.

The CPU 11 determines which key of the input unit 18 has been input (step S10).
In step S10, the CPU 11 updates the numbers on the display unit 14 and the customer display unit 15 (step S11) if the number key of the input unit 18 is pressed, and resets the subtotal key count variable (step After S18), the process returns to step S10.
If the "x" key is pressed in step S10, the CPU 11 proceeds to step S12 in which the number on the display unit 14 or the customer display unit 15 is determined as the product quantity, and resets the variable for the number of subtotal keys (step S18). After that, the process returns to step S10. Specifically, when the operator inputs the product quantity, the operator may enter the product quantity with 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 for determining the number on the display unit 14 or the customer display unit 15 as the internal tax system of the standard tax rate, and proceeds to the "Department 2" key. If is pressed, the process proceeds to step S14 in which 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, the variable of the subtotal key count is reset (step S18), and then the step S10 Return to processing.
Specifically, when the operator inputs the product price with the numeric keys and then presses the "department 1" key, the price of the product with the standard tax rate is input by the internal tax system. 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 system.

In step S10, if the "department 3" key is pressed, the CPU 11 determines the number on the display unit 14 or the customer display unit 15 as the standard tax rate external tax system (step S15), and the "department 4" key. If 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), the variable for the number of subtotal keys is reset (step S18), and then the step S10. Return to processing.
Specifically, when the operator inputs the price of the product with the standard tax rate by the external tax method, the operator may press the "department 3" key after inputting the product price with the numeric keys. Further, when the operator inputs the price of the product with the reduced tax rate 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 for determining 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. After resetting the variable for the number of subtotal keys (step S18), the process returns to step S10. Specifically, when the operator designates a product by the PLU number, the "PLU" key may be pressed after inputting the PLU number with the numeric keys.

If the "subtotal" key is pressed in step S10, the CPU 11 derives the subtotal amount of the product corresponding to the standard tax rate and the subtotal amount of the product corresponding to the reduced tax rate (step S19). The CPU 11 determines the number of times the "subtotal" key is pressed (step S20). If the "subtotal" key is pressed for the first time, the CPU 11 outputs the subtotal amount of the entire sales to the display unit 14 or the customer display unit 15 (step S21), and if it is pressed for the second time, the product corresponding to the standard tax rate is displayed. The subtotal amount is output (step S22), and if it is the third press, the subtotal amount of the product corresponding to the reduced tax rate is output (step S23), and then the process returns to step S10. The number of times the "subtotal" key is pressed is reset by the processing in step S18 described above.

FIG. 11 is a flowchart showing the product registration process.
This product registration processing is executed by the operation of the CPU 211 of the product identification device 2.
First, the CPU 211 of the product identification device 2 determines which key has been input (step S30).

In step S30, if the ten-key pad of the keyboard 23 is pressed, the CPU 211 determines the product quantity (step S31), and the process returns to step S30.
If the keyboard 23 is not pressed in step S30, the CPU 211 determines whether the camera 27 images the product and scans the barcode (step S32). If the barcode is scanned in step S32, the CPU 211 identifies the product and the tax rate (step S33), multiplies the product quantity by the product unit price to calculate the price (step S34), and the subtotal in step S35. Proceed to the derivation process.

In step S30, if the subtotal key of the keyboard 23 is pressed, the CPU 211 derives each subtotal amount for this customer (step S35). Further, the CPU 211 outputs the subtotal amount of the product corresponding to the reduced tax rate to the display 221 or the customer display 24 (step S36), and outputs the subtotal amount of the product corresponding to the standard tax rate (step S37) to the customer. The total amount of sales is output (step S38), and the process returns to step S30. The small plan surface 7 displayed on the customer display 24 at this time will be described with reference to FIGS. 12 and 13 described later.

FIG. 12 is a diagram showing a first display example of the small plan surface 7.
