Next, an accounting process procedure by the sales data processing apparatus 1 will be described.
FIG. 6 is a flowchart showing the procedure of the accounting process by the sales data processing apparatus 1 in this embodiment.
First, in step S <b> 101, the sales data processing apparatus 1 accepts input of the number of people who purchase products (the number of trading customers). Specifically, the CPU 11 displays an input screen for inputting the number of products purchased on the store clerk display unit 14. The store clerk can specify the number of people using the operation unit 15 or the touch panel. The number of persons can be changed and input even during the flow shown in FIG.

Next, in step S102, the sales data processing apparatus 1 registers a product purchased by the customer (hereinafter referred to as a purchased product). Specifically, the CPU 11 temporarily stores, in the RAM 13, the result of the store clerk operating the sales data processing apparatus 1 reading the barcode added to the product using the scanner unit 18.
Next, in step S103, the sales data processing apparatus 1 displays the transaction information shown in FIG. The accounting information is the details of the product registered in step S102. Specifically, the CPU 11 refers to the data temporarily stored in the RAM 13 and the product file to generate transaction information. At this time, the CPU 11 calculates the purchase points, subtotal, taxable amount, total tax amount, and total amount of the purchased product. Then, the CPU 11 displays the generated transaction information on the salesclerk display unit 14.

FIG. 7 is an example of a screen displayed on the salesclerk display unit 14 of the sales data processing apparatus 1 in the present embodiment.
The screen shown in this figure displays a product list 71 as accounting information, the number of purchases of purchased products, a subtotal, a taxable amount, a total tax amount, and a total.
The product list 71 displays a list of product names, purchase quantities, purchase amounts, and the like of each purchased product. Here, “special” is displayed beside the purchase price in order to indicate that it is a special sale product. When the products displayed in the list include special sales products, it is possible to select the special sales products by touching the clerk display unit 14. When the number of family buttons 72 shown in FIG. 7 is touched, an input screen for the number of customers who purchase products (the number of transaction customers) is displayed on the store clerk display unit 14. As indicated by reference numeral 71, the purchase quantity of the egg, which is a special sale product, is 6 in this transaction. Since the customer purchase limit of the egg is 2, the accounting information is generated with the purchase price of 2 packs of eggs as the sale price and the purchase price of the remaining eggs as the normal price.

  Next, in step S104, an input of the purchase quantity of the product is accepted. Specifically, the CPU 11 displays a screen for inputting the purchase quantity of the selected product on the store clerk display unit 14. At this time, the CPU 11 adds and sets the amount of the product scanned by the scanner unit 18 as a purchase quantity and displays it on the screen. The store clerk can directly change the purchase quantity using the operation unit 15 or the touch panel. Further, the store clerk can change the quantity by selecting a product and inputting the purchase quantity after pressing the X key of the operation unit 15.

  Next, in step S105, the sales data processing apparatus 1 determines whether or not the registered product is a product that is restricted in purchase (sale product). If the purchase is restricted, the process proceeds to step S106. On the other hand, if the product is not subject to purchase restrictions, the process proceeds to step S117.

  Next, in step S106, the sales data processing apparatus 1 calculates a purchaseable quantity that is a quantity that allows the sale item to be purchased at a sale price in this transaction. Specifically, the CPU 11 calculates the purchaseable quantity by multiplying the input number of trading customers by the value of the one-customer purchase limit of the special sale product set in the product file.

Next, in step S107, the sales data processing apparatus 1 determines whether or not the purchaseable quantity of the special sale product exceeds the transaction number upper limit set for the special sale product in the product file. If the transaction upper limit is not exceeded, the process proceeds to step S108. On the other hand, when exceeding a transaction upper limit, it progresses to step S113.
In step S108, the sales data processing apparatus 1 determines whether or not the purchase quantity exceeds the purchaseable quantity. If the purchaseable quantity is not exceeded, the process proceeds to step S109. On the other hand, if the purchaseable quantity is exceeded, the process proceeds to step S110.
In step S109, the sales data processing apparatus 1 stores the purchase quantity in the RAM 13 in association with the sale price of the sale item.

On the other hand, in step S110, the sales data processing device 1 stores the purchaseable quantity in the RAM 13 in association with the sale price of the sale item as the first purchase quantity.
Next, in step S111, the sales data processing apparatus 1 calculates a purchase quantity that exceeds the purchaseable quantity. Specifically, the CPU 11 subtracts the purchaseable quantity from the purchase quantity to obtain the second purchase quantity.
Next, in step S112, the sales data processing apparatus 1 stores the calculated second purchase quantity in the RAM 13 in association with the normal price of the sale item.

On the other hand, in step S113, the sales data processing apparatus 1 determines whether the purchase quantity does not exceed the transaction number upper limit value. If the transaction number upper limit is not exceeded, the process proceeds to step S109. On the other hand, when exceeding the transaction number upper limit, it progresses to step S114.
In step S114, the sales data processing apparatus 1 stores the transaction number upper limit value as the first purchase quantity in the RAM 13 in association with the sale price of the sale item.
Next, in step S115, the sales data processing apparatus 1 calculates the purchase quantity exceeding the transaction number upper limit value. Specifically, the CPU 11 calculates the second purchase quantity by subtracting the transaction number upper limit value from the purchase quantity.
Next, in step S116, the sales data processing apparatus 1 stores the calculated second purchase quantity in the RAM 13 in association with the normal price of the sale item.

In step S117, the sales data processing apparatus 1 determines whether or not the subtotal key provided in the operation unit 15 is pressed. If the subtotal key is pressed, the process proceeds to step S118. On the other hand, if not pressed, the process returns to step S102.
In step S118, the sales data processing apparatus 1 determines whether the correction / return key provided in the operation unit 15 has been pressed. If the correction / return key is not pressed, the process proceeds to step S120. On the other hand, if it has been pressed, the process proceeds to step S119.
In step S119, the sales data processing apparatus 1 performs the quantity correction of the product specified in the product list 71 and the return processing of the product that does not require purchase, and returns to step S102.

On the other hand, in step S120, the sales data processing apparatus 1 displays the transaction information shown in FIG. At this time, the CPU 11 refers to the data temporarily stored in the RAM 13 and generates the accounting information again.
FIG. 8 is an example of a screen when the number of business customers input in step S104 is 3 in the example shown in FIG. Here, the one-customer purchase limit, which is the maximum number of items that can be purchased by one customer at a special price, is two. For this reason, the purchaseable quantity, which is the quantity at which the product can be purchased at a special sale price in this transaction, is “number of customers (3) × one customer purchase limit (2) = 6”. However, since the maximum number of transactions, which is the maximum number of eggs that can be purchased at a sale price in one transaction, is 4, the number of eggs that can be purchased at a sale price is only 4 packs. For this reason, in the accounting information shown in this figure, as indicated by reference numeral 80, the purchase price of 4 packs of eggs is the sale price, and the purchase price of 2 packs of eggs is the normal price.

Next, in step S121, the sales data processing apparatus 1 registers the deposit amount received by the store clerk from the customer. The store clerk performs amount registration using the operation unit 15. Alternatively, the deposit amount received from the customer may be confirmed based on the amount deposited at the deposit input port 17b of the automatic change machine 17.
Next, in step S122, the sales data processing apparatus 1 determines whether or not a current key provided in the operation unit 15 is pressed. If the current key is pressed, the process proceeds to step S123. On the other hand, if the current key has not been pressed, the process returns to step S102.
In step S123, the sales data processing apparatus 1 prints and issues the receipt shown in FIG. 9 or 10 from the receipt printing unit 19. At this time, the CPU 11 generates accounting data to be printed on the receipt based on the accounting information generated in step S120 and the deposit amount.
In step S124, the sales data processing apparatus 1 stores the receipt-printed transaction data in the RAM 13, ends the current transaction, and prepares for the next transaction. The accounting data stored in the RAM 13 is transmitted to the store controller 2 as sales data via the LAN in a date closing process executed at the end of the day.

FIG. 9 is a schematic diagram illustrating an example of a receipt issued by the sales data processing apparatus 1 according to the present embodiment.
The example shown in this figure is a receipt that is issued when two family members purchase two eggs each of which is a special sale product. Here, the number of eggs that can be purchased by one customer is limited to 2 packs. Further, the upper limit of the number of transactions of egg is 4. In the area indicated by reference numeral 81 of the receipt shown in FIG. 9, the transaction information of the egg is printed. As for the egg, 4 packs are purchased at a special price of 98 yen, and 2 packs are purchased at a regular price of 128 yen. This is because the sale price is not applied to the quantity exceeding the upper limit of the number of transactions. In this figure, the limited number is a value of one customer purchase limit.

FIG. 10 is a schematic diagram showing another example of a receipt issued by the sales data processing apparatus 1 in the present embodiment.
In the receipt shown in this figure, the accounting information for the special sale product and the accounting information for the other products are printed separately. In the example shown in FIG. 10, the accounting information of the special sale product is printed in an area 91 different from the accounting information of the other products. At this time, in S120 described above, accounting information (purchased points and subtotals) only for the sale items and accounting information (purchasing points and subtotals) only for the other products are further calculated. Note that a cut line may be put in the broken line portion 92 of the receipt shown in FIG.

As described above, according to the present embodiment, it is possible to perform accounting processing for a sale item with a quantity corresponding to the number of input customers. For this reason, when multiple family members who have purchased a special sale product with a limited quantity that can be purchased by one customer purchase each, the number of people who purchase the product without accounting for each customer separately Can be accounted for in one transaction. As a result, the trouble and time for performing accounting processing separately for each customer are eliminated, so that customer waiting for accounting can be eased. Further, receipts for the number of people who purchase the products can be printed and issued together, so that consumables and expenses are not wasted.
In addition, since the amount of the purchase of the special sale product that exceeds the upper limit of the number of transactions is accounted for as the normal price, it is possible to prevent illegal sale of the special sale product, and it is appropriate to spread evenly to the customers who visited the store. Products can be sold at reasonable prices and quantities.
In addition, because it is possible to print separately the accounting information for special sales products and the accounting information for other products, it is easy to visually check the transaction details when corrections or returns are made on special sales products. Follow-up surveys are easier when such problems occur.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
For example, in the present embodiment, the merchandise displayed on the clerk display unit 14 is selected and the number of transactions is input, but the sales data processing device 1 automatically extracts the special sale merchandise and displays the clerk display unit. 14 may display a list of special sale products extracted. Alternatively, when the family number button 72 is touched, a list of sale items may be displayed on the display 14 for the clerk.
In this embodiment, the accounting information of the special sale product and other products is printed on one receipt. However, the accounting information of the special sale product and the accounting information of other products are printed on separate receipts. Also good.
In the present embodiment, the sales data processing apparatus 1 is a POS register. However, a portable terminal capable of accounting processing may be provided with the function of the sales data processing apparatus 1 shown in FIG.
