Description

The present invention relates to a sales data processing apparatus and a sales data processing 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 of 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, and eating and drinking at the eat-in corner of the convenience store. Food and beverages, 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. "

Further, every time the operator registers the product, the CPU 11 repeats the processes of steps S10 to S18. In this flowchart, the process when the "current / 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, 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 resets the variable for the number of subtotal keys (step). After S18), the process returns to the process of 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 resets the variable of the number of subtotal keys (step S18). ), Then the process returns to 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 tax-included method of the standard tax rate, and proceeds to the "department 2" key. If 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, resetting the variable for the number of subtotal keys (step S18), and then in step S10. Return to processing.
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 tax exemption method of the standard tax rate (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 tax exemption method (step S16), the variable for the number of subtotal keys is reset (step S18), and then step S10. Return to the processing of.
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 for determining the product, the unit price, the tax rate, and the calculation method, using the numbers of the display unit 14 and the customer display unit 15 as the PLU number. After resetting the variable of the number of subtotal keys (step S18), the process returns to the process of step S10. Specifically, when the operator specifies a product by the PLU number, the operator may press the "PLU" key after inputting the PLU number with the number keys.

In step S10, if the "subtotal" key is pressed, 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 the first time, the CPU 11 outputs the subtotal amount of the entire sales to the display unit 14 and the customer display unit 15 (step S21), and if the "subtotal" key is pressed the second time, the product corresponding to the standard tax rate. After outputting the subtotal amount (step S22) and outputting the subtotal amount of the product corresponding to the reduced tax rate if pressed for the third time (step S23), the process returns to the process of step S10. The number of times the "subtotal" key is pressed is reset by the process of step S18 described above.
