DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

In FIG. 2, 1 is a merchandise sale product (hereinafter,
2 is a bag for the purchaser to put the product 1 in, and it is advisable to place it in the sales floor adjacent to the product 1. A label 3 having a bar code 4 representing a weight unit price (gram unit price, etc.), a weight sale classification code, and a product code is attached to an appropriate place of the bag 2. The barcode 4 may be printed directly on the bag 2. The purchaser takes the required amount of the product 1 in the bag 2 and directly carries it to the checkout place for payment.

Depending on the type of the product 1, it is possible to directly attach the label 3 to the product 1 or directly print the bar code 4. However, the product 1 in the bag 2
If you decide to put in, the optional number (weight) of product 1
It can be said that it can be handled collectively, which is convenient for improving the efficiency of settlement work.

In FIG. 1, reference numeral 10 denotes a POS terminal device installed at a checkout station, which includes a bar code reader 11, a keyboard 12, a measuring instrument (electronic scale) 13, as an input device, and an input / output device. Is connected to the auxiliary storage device 14. The product master file 15 is stored in the auxiliary storage device 14. Although not shown, the POS terminal device 10 is connected to a communication line network or a store controller, and directly or via the store controller.
It is possible to communicate with the center device of the system.

The POS terminal device 10 includes a display device 16 for displaying information to an operator or a purchaser, and a printing machine 17 for issuing receipts. In addition, the POS terminal device 10
Is a central processing unit (CPU) 21, a memory 22 for storing programs and data, and an input / output device (11, 1).
2, 13, 14, 16, 17), and an internal processing system including an I / O interface section 23 for interfacing with a store controller and a host interface section 24 for communication with a center device. The determination of the selling price of the merchandise sale product is realized by software in this internal processing system, and the program therefor is stored in the memory 22.
Memorized in.

Next, the processing at the time of settlement of the merchandise sold for sale will be described. The purchaser takes the required amount of the product 1 in the bag 2 and carries it to the checkout office. The store clerk puts the bag 2 containing the product 1 on the weighing machine 13 and weighs it, and also the bar code 4 of the bag 2 is read by the bar code reader 11.

The bar code reader 11 reads the information of the bar code 4, that is, the unit price for weight, the division code for merchandise sales and the product code, which is read as input data from the I / O interface section 23 into the CPU 21 and stored in the memory 22. Stored in the input buffer. The weight data weighed by the weighing device 13 is also read via the I / O interface 23 and stored in the input buffer on the memory 22.

When the metering sale classification code is input in the input buffer, the CPU 21 (settlement processing program) calculates the selling price by multiplying the weight unit price and the weight data in the input buffer, and calculates the selling price. The data is stored in the output buffer on the memory 22. The CPU 21 also
The product name corresponding to the input product code is read from the product master file 15 in the auxiliary storage device 14 and stored in the output buffer. Then, the information such as the product name, the weight, and the selling price obtained in the output buffer is displayed on the display device 16, and the information is printed on the printing machine 17 when the receipt is issued.

As described above, since the unit price of weight for determining the selling price of the merchandise to be sold is input from the bar code reader 11, it is not necessary to register the unit price of weight in the product master file 15. Therefore, even if the unit price of the weight-sales product is changed or the price is reduced before the store is closed, it is not necessary to update the product master file 15.

When the bag 2 (or the product 1) does not have the bar code 4 and the bar code reader 11 cannot input the product code or the unit weight, the weighing button on the keyboard 12 is pressed (the metering division code is input. Enter the unit price and product code. Even in this case, the selling price is determined by calculation, and only the product name is fetched from the product master file 15.

If the product is not a merchandise sale product, the merchandise sale classification code is not input. In this case, the CPU 21 reads not only the product name but also information such as the selling price from the product master file 15 based on the product code and displays or prints it.

In addition to the processing described above, various processings such as sales price integration, change calculation, and sales totalization are performed. However, since these processing contents are the same as those of the conventional POS terminal device, description thereof will be omitted.

[0020]

As described above, according to the present invention, it is possible to automatically determine the selling price of a merchandise selling product such as fresh food whose price fluctuates depending on the day or time, at the time of sale. At that time, the unit weight is read from the bar code and entered, so it is not necessary to register the unit weight of the weight-selling product in the product master file. This frees you from the hassle of performing update processing. Further, since the update process is not cumbersome, it becomes easy to flexibly set the price of the merchandise sale product in the store. For example, when the price is reduced by closing the store, it is sufficient to prepare a bag having a label printed with the weight unit price barcode to be reduced and replace it.
