Description

[Detailed Description of the Invention] Industrial Application This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an improvement of ECR in which the department and amount of the product are recorded on each product using a barcode, and data regarding each product is registered by reading the barcode.

Conventional techniques There are two methods for inputting product-related data using an ECR: a keyboard input method and a barcode reading method. In the keyboard input method, an operator operates a keyboard to input the department and price of the sold product. In the barcode reading method, information such as the department and price of the product is recorded on the product in advance using a barcode, and the barcode is read and input using a barcode reading means called a scanner. Such a barcode reading method has the advantage that it is not necessary for the operator to operate a keyboard, so data related to the product can be registered quickly.

Incidentally, the selling price of fresh foods such as meat and fish is determined based on the unit price per duram, and the price is recorded on the product using a barcode. The quantity of sold products increases by 1 for each product registered.
be done. However, in the case of fresh foods, the important point is how many grams are sold rather than the quantity of products sold.

Problems to be Solved by the Invention Conventional EGR cannot calculate the total quantity of sold products per unit duram.

Therefore, the main object of the present invention is to provide an ECR that registers data regarding products by reading barcodes and can calculate the total quantity of 1c products sold, for example, per unit duram. That's true.

Specific Means for Solving the Problems This invention provides a barcode reading means for reading a barcode recorded on a product and indicating the category and amount of the product, and a barcode reading unit that reads a barcode recorded on a product and indicating the category and amount of the product, and The unit price storage means stores the unit price of each product in advance, the quantity storage means stores the sales quantity of each product for each department, and the control means controls these means.

The action control means reads the unit price per unit quantity corresponding to the department included in the barcode from the unit price storage means by the barcode reading means, and reads the unit price per unit quantity;
The quantity of sold products is calculated based on the amount included in the barcode, and the calculation result is stored in the quantity storage means in correspondence with the corresponding department.

The present invention will be explained in more detail below along with embodiments shown in the drawings.

The deposit/total key 243 is operated to perform calculations such as change when the customer pays cash. The @ key 244 is operated to register the input quantity when a customer purchases the same product and the operator inputs the quantity using the numeric keypad 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, keyboard 3, front display 4, and customer display 5 shown in FIGS. 2 and 3 described above are shown. and printer 6 are connected to CPU 9, respectively. A ROM 10 and a RAM 11 are connected in relation to the CPLI 9. The ROM 10 stores in advance programs necessary for the CPU 9 to operate. The RAM 11 stores data as shown in FIGS. 5A and 5B, which will be described later.

5A and 5B are diagrams showing data stored in the RAM 11 shown in FIG. 4. Figures 5A and 5
Referring to Figure B, the RAM 11 mainly includes an area 12 as a totalizer and counter, and a PLIJ file 13. The totalizer and counter are for storing the total amount and total number of products registered so far.

As shown in FIG. 5B, the PLU file 13 includes an area 131 for storing the PLU code, an area 132 for storing the product name, that is, the disc libter, an area 133 for storing the unit price, that is, the unit price per unit gram, and the area 133 for storing the product name, that is, the disc libter. It includes an area 134 for storing the total amount and an area 135 for storing the quantity per gram.

FIG. 1 is a flowchart for explaining the specific operation of an embodiment of the present invention, and FIG. 6 is a diagram showing an example of a barcode.

Next, with reference to FIGS. 1 to 6, a specific operation of an embodiment of the present invention will be described.

The operator takes out the products purchased by the customer from the shopping section 7 and places them on the scanner 2. A bar code 14 as shown in FIG. 6 is recorded on each product. This barcode 14 includes product code 141 and unit price check digit 1
42 and unit price 143. The scanner 2 reads the barcode and provides it to the CPU 9. The CPU 9 checks the barcode given from the scanner 2 and determines whether or not the barcode includes a unit price code.

This is because a barcode does not necessarily include a unit price code. In other words, only the product code is recorded in the barcode, and the unit price preset in the memory may be read out and registered based on the product code. If the barcode includes a unit price code, the C, PU 9 displays the unit price on the front display 4 and the customer display 5, and further prints the unit price on the receipt using the printer 6.

Furthermore, the CPU 9 searches the PLU file 13 included in the RAM 11 based on the product code 141 read from the barcode, refers to the PLU code area corresponding to the product code, and calculates the Yukot unit price from the area 133. Read out. Then, the unit price code in the barcode is divided by the unit price read from the PLU file 13 to obtain the number of grams of the product, and this is registered in the area 135 of the PLU file 13. Roughly, the unit price in the barcode is registered in the total area 134.

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

If the customer has purchased multiple items of the same item, the operator inputs the number using the numeric keypad 22 and operates the @ key 244. CPLI9 is @key 24
4 is not operated, the data in the quantity area 135 corresponding to that product in the PLU file 13 is incremented by 1.

If the @ key 244 is operated, the data in the quantity area 135 is incremented by the number input from the numeric keypad 22.

Then, 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 Total area 134
Register.

The above-described series of operations is performed for each product purchased by the customer, and when the registration of all products is completed, the deposit/total key 243 is operated to calculate the total.

As described above, according to this embodiment, if the unit price code is included in the barcode, the PLU file 13
You can read out the unit price of that product, divide the unit price read from the barcode by the unit price to find the quantity per gram, and register that quantity. You can know how many grams of a product has been sold, and you can obtain useful information for sales and inventory management.

Effects of the Invention As described above, according to this invention, when registering perishable foods, it is possible to indicate, for example, how many grams of the product have been sold in terms of quantity, which is very useful information for sales and inventory management. can be obtained.
