Note that the preset data area also stores data for fixed price products, but since the fixed price products are not directly related to the present invention, a description thereof will be omitted. Next, each process of this embodiment with the above configuration will be explained. ◎Price calculation process (Figure 5) Step SAI: The store clerk selects the product key corresponding to the product that the customer wishes to purchase from among the product keys displayed on the touch panel of the sales data processing device 1's display section 6 for the store clerk. When touched, the product number (PLU, NO) of the corresponding product is displayed. In this case, for example, "Toriniku J
When you touch the part that says (chicken), the product number r1234J of "Toriniku" is input. Incidentally, the product number can also be input by operating the numeric keypad "IJr2JF3Jr4J and F product number" keys of the keypad section 7. Step SA2 When the product number that the customer wishes to purchase is input, the CPU], 1 is the product file 13B in the RAM 13.
is searched using the product number as a search key, and the product data (product name/unit price (1)
), unit price (2), and unit price (3)) are read out and stored in each register in the working area 13A, and the stored contents of the register are displayed on the clerk display section 6 and the customer display section 17.
Display to. In this case, since there is no product placed on the 1m2 scale (weighing value Og), the store clerk display section 6 and the customer display section 1
7 displays the unit price (1) when the weight value is the lowest (weight 1w≦200g). If the customer-purchased product has already been weighed before inputting the product number, the unit price selected based on the weighed value of the customer-purchased product will be displayed in the process of step SA4, which will be described later. Step SA3: When the store clerk places M the amount of product that the customer desires to purchase on the weighing plate 2, the weight W of the product is measured by the weighing unit 16.
is measured and input to CPU II. This results in
The CPU II stores the weight iW of the product in a register in the working area 13A of the RAM 3, and displays it on the clerk's display section 6 and the customer's display section 17. Product file 1 of STAY 7' S A /I: CPU]

is selected (step 5A42). In this case, the unit price (1) displayed on the display section 6 for two members and the display section 17 for customers at Step SA 2 does not change. On the other hand, if the weight W is 20
If it exceeds 0g, it is determined whether it is 500g or less (Step SA 43), and if it is 500g or less, the unit price (2) is selected as the product unit price (Step SA 44). If it is very sharp, select unit price (3) as the product unit price (Step 5)
A45). In addition, in the case of step 5A44 and step 5A45, -
In step SA2, the store clerk display section 6 and the customer display section 1 are
The unit price (1) displayed in 7 is cleared, the unit price (2) and the unit price (3) are displayed, and it is also displayed that the unit price is the service price because the customer purchased a large quantity of products. In this case, the store clerk will explain this to the customer when the display is made. Step SA5: The CPU 1.1 calculates the price of the product by multiplying the unit price of the product selected in step SA4 by the product weight W. Step SA6: Then, the CPU II displays the product price calculated in step SA5 on the store clerk display section 6 and the customer display section 17. In addition, when calculating and displaying the price based on the unit price selected according to the measured value of the product purchased by the customer, in order to make it possible for the customer to confirm the degree of profit, the unit price (A) of the product with a weight of Og is calculated and displayed.
The price (, P) calculated from (highest unit price - normal unit price) and the discount amount Q (-1h stage (P) - price (1") calculated from the unit price according to weight W) are displayed for customers. 17 and the clerk's display section 6. ◎Discount amount printing process (Fig. 7) In the discount amount printing process, the unit price (A) when the weight is Og.
Print the price (P) calculated from (the highest unit price - usually 11 prices) and the discount amount Q (- price (P) - price (1)'' calculated from the unit price according to weight W)) on the receipt. (In this embodiment, when issuing a receipt, only the fIi stage (P) of the discount 111 is displayed on the customer display gtSl 7.) When the customer touches the product key corresponding to the product he/she wishes to purchase among the product keys displayed on the touch panel, the product number (PLU, NO) of the corresponding product is input.Step SB2 Product the customer wishes to purchase When the number is input, the CPU II searches the product file 13B in RAM 3 using the product number as a search key, and retrieves the product data (product name/unit price (1)) stored corresponding to the product number.
, unit price (2), and unit price (3)) are read out and stored in each register in the working area 13A, and the stored contents of the register are displayed on the clerk display section 6 and the customer display section 17. Step SB3: The clerk places the amount of products desired by the customer on the weighing plate 2.The weight W of the product is measured by the weighing section 16 and input to the CPU II. As a result, C
The PUII stores the weight W of the product in the register in the working area 13A of the RAM 13, and also
and displayed on the customer display section 17. Step SB4: The CPU 11 multiplies the unit price (A) (highest unit price - normal unit price) when the product weight is assumed to be Og by the product type i1W to calculate the non-discounted price (P). Step SB5: Then, the CPU II displays the above-mentioned non-discounted price (P) on the clerk's display section 6 and the customer's display section 17. Step SB6: Above steps SB3 to S

The journal printer 14 prints the product name (Trinik)/unit price (200 yen) on the receipt R as shown in FIG. 8, for example.
/Purchase weight (400g)/Undiscounted price (800g)
yen)/discount amount (80 yen), etc. The receipt R is issued from the receipt issuing port 5 of the sales data processing device 1 and handed to the customer by the clerk. The discount amount printing process in Figure 7 is an example in which product data is printed on a receipt each time one product is registered, but when the same customer purchases multiple products, each product data is stored in the receipt printing buffer. You may memorize the information and then print and issue a receipt when purchasing the last item and paying the bill. In this case, if the same customer purchases the same product multiple times with other products in between, the unit price will be determined based on the total weight, and the discount amount will be deducted from the price calculated based on the unit price. It is also conceivable to configure it so that it is determined and printed. For example, a customer received 40 yen the first time they tried ``Toriniku''.
When purchasing 0g and purchasing 200g a second time, the unit price is determined by the total purchased weight of 400g + 200g = 600g, and the discount amount is calculated and displayed. In this embodiment, a sales data processing device integrated with an ECR has been described, but the present invention can also be applied to a weighing label printer for pricing pre-packed products. Also,
Although the sales data processing device of this embodiment is a stand-alone type, it is a parent-child type or store controller type system, and each child device or each terminal calls and uses the product file stored in the parent device or store controller. It is also possible to do this.

[Modified example]

■ In the above embodiment, as shown in FIG.
The system is structured so that customers can select one according to the weight of the product they have purchased. In the case of the above embodiment, the weight classification, which is the basis for selecting which of the plurality of unit prices, is the same for each product, but it is not limited to this. For example, as shown in FIG. Weight classification when selecting unit price in 23B (
Weight (1): 200g, Weight (2): 500g
) may be stored. In other words, in Figure 9, if the weight is 200g or less, the unit price to be selected is 200 yen,
This indicates that if the weight exceeds 200g and is less than 500g, the unit price to be selected is 180 yen, and if the weight exceeds 500g, the unit price to be selected is 150 yen. This configuration has the advantage that weight categories can be set for each product. In this case, since products with high unit prices tend to be purchased in small quantities by customers, it may be possible to adopt a setting method in which weight categories are subdivided for products with high unit prices compared to products with low unit prices. . ■In the above embodiment and the above modification ■, a plurality of unit prices for one product are stored in the product file, but the invention is not limited to this. For example, as shown in FIG. In addition to storing one unit price for one product, a discount amount (discount rate) for each weight category may also be stored. In other words, in Figure 10, if the weight is 200g or less, the discount is 0 yen, if the weight exceeds 200g and is 500g or less, the discount is 20 yen (equivalent to a discount ('')), and if the weight exceeds 500g, the discount is 0 yen. In that case, there will be a discount or 50 yen (discount (2)
). ■In the above modification ■, one unit price and discount amount for each weight category are stored for one product in the product file 33B, but the invention is not limited to this. One 11 for one product in 43B
11[11i, weight classification, and discount amount for each weight classification may be stored. In other words, in Figure 1J, if the weight is 200g or less, the discount is 0 yen, and if the weight exceeds 200g but is 500g or less, the discount is 20 yen (discount (1)
), and if the weight exceeds 500 g, there is a discount of 50 yen (corresponding to discount (2)). ■ In the above embodiments and modifications ■ to ■, the weight category and the discount amount are set individually, but the product file 53B is not limited to this, for example, as shown in FIG. 12.
A discount amount (or discount rate) that is given each time a predetermined weight exceeds a predetermined weight may be stored therein. That is, FIG. 12 shows that after the weight of the product exceeds 200g, a discount of 20 yen is set for each weight exceeding 200g. For example, if the unit price is 200 yen when the weight W is 200g or less, the unit price is 180 yen if the weight W exceeds 2QOg and is 400g, and the unit price is 600g when the weight W exceeds 400g.
The unit price in the following cases will be 160 yen. In this case, in order to prevent the situation where the unit price becomes 0 yen when the customer purchases a large amount of products, it is necessary to set the limit value (maximum value) of the discount to a predetermined value such as 80 yen. It is desirable to set it to the amount of money. ■'' In the case of Example 2 and the above modifications ■ to ■, for example, in the case of modification ■, when a customer purchases 400g of a product, the unit price is 180 yen/100g, so the price of the product is 400X ( 180/101)) -720 yen, but it is not limited to this and may be calculated as follows. In this variation ■, when a customer buys 400g of a product, for example, the unit price is 2 for up to 200g of the 400g.
[Calculated at 10 yen, remaining 201 exceeding 200 g
Unit price 180 for 1g (400g-200g)
It is calculated in yen, 400 yen - 200g x (
200 yen/+ug), 360 yen-200g
g (1 yen/IQOg), the price of 400g of product is 760 yen. That is, in this modification (2), only the weight exceeding the weight category is calculated using the unit price of the weight category. This modification example ■ is the above-mentioned example or the above modification example ■
~■ It is also applicable to each case. Furthermore, the expression "product number" used in the specification of this application means the symbols assigned to each product to identify the product, and in the examples, numbers are used.
