The subtotal key 242 is operated when obtaining the total of the amount data of the products registered so far. The deposit / cash total key 243 is operated to perform calculation such as change when the customer pays cash. When the customer purchases the same product, the @ key 244 is operated in order to register the entered quantity if the operator inputs the quantity from the ten key 22 and then operates the @ key 244.

FIG. 4 is a schematic block diagram of an embodiment of the present invention.
In FIG. 4, the scanner 2, the keyboard 3, the front display 4, the customer display 5 and the printer 6 shown in FIGS. 2 and 3 are connected to the CPU 9, respectively. CP
ROM10 and RAM11 are connected in relation to U9. ROM10 is CPU
The programs necessary for 9 to operate are stored in advance. The RAM 11 stores data as shown in FIGS. 5A and 5B described later.

FIGS. 5A and 5B are diagrams showing data to be stored in the RAM 11 shown in FIG. Referring to FIGS. 5A and 5B, RAM 11 mainly includes area 12 as a totalizer and counter and PLU file 13. The totalizer and counter store the total amount and total number of products registered so far. As shown in FIG. 5B, the PLU file 13 has an area 131 for storing the PLU code.
And an area 13 that stores the product name, that is, the descriptor

FIG. 1 is a flow chart for explaining a concrete operation of one embodiment of the present invention, and FIG. 6 is a diagram showing an example of a bar code.

Next, the specific operation of the embodiment of the present invention will be described with reference to FIGS. The operator takes out the product purchased by the customer from the shopping basket 7 and uses the scanner 2
Place it on top. A bar code 14 as shown in FIG. 6 is recorded on each product. This barcode 14 is the product code
141, unit price check digit 142, unit price 143 and the like. The scanner 2 reads the bar code and gives it to the CPU 9.
The CPU 9 checks the bar code given from the scanner 2 and determines whether or not the unit price code is included in the bar code. This is because the barcode does not always include the unit price code. That is, only the product code may be recorded in the bar code, and the unit price preset in the memory based on the product code may be read and registered. If the unit price code is included in the bar code, the CPU 9 displays the unit price on the front display 4 and the customer display 5, and the printer 6 prints the unit price on the receipt.

In addition, CPU9 reads the product code 141 read from the bar code.
The unit price is read from the area 133 by searching the PLU file 13 included in the RAM 11 and referring to the area of the PLU code corresponding to the product code. Then, the unit price code in the bar code is divided by the unit unit price read from the PLU file 13, the number of grams of the product is obtained, and this is registered in the area 135 of the PLU file 13. Further, the unit price in the barcode is registered in the total area 134.

If the unit price code is not included in the barcode, based on the product code read from the barcode,
The PLU file 13 is searched and the area of the corresponding PLU code is searched.
The preset unit price is read out from 133, displayed on the front display 4 and the customer display 5, and printed on the receipt by the printer 6.

If the customer purchases a plurality of the same products, the operator inputs the number from the ten key 22 and operates the @ key 244. If the @ key 244 is not operated, the CPU 9 increments the data of the quantity area 135 corresponding to the product in the PLU file 13 by 1. If the @ key 244 is operated, the data in the quantity area 135 is incremented by the number input from the ten key 22. If the @key 244 is not operated, the unit price is registered in the total area 134 of the PLU file 13, and if the @key 244 is operated,
The unit price is multiplied by the quantity, and the result is registered in the total area 134.

After the series of operations described above is performed for each product purchased by the customer and registration of all products is completed, the deposit / cash total key
Operate 243 to perform total calculation.

As described above, according to this embodiment, when the unit price code is included in the bar code, the unit unit price of the product is read from the PLU file 13, and the unit price read from the bar code is divided by the unit unit price. Then, you can obtain the quantity per gram and register that quantity.
It is possible to know not only the number of products but also how many grams of the product has been sold, and it is possible to obtain useful information for sales and inventory management.

EFFECTS OF THE INVENTION As described above, according to the present invention, when registering a perishable food product, for example, it is possible to show how many grams of a product have been sold by a quantity, which is very useful information for sales and inventory management. Can be obtained.
