Description

Description: TECHNICAL FIELD The present invention relates to a bar code processing device for a weighing and pricing machine used in a retail store or the like in which a point-of-sale information management system (POS system) is introduced.

(Prior art and its problems) In the POS system introduced in retail stores and the like, a POS register in which the manufacturer code and the product code are represented by a bar code and the selling price of each product is stored in advance is prepared. Every time, by reading the bar code of the product, the POS register reads the price of the product to register the sales price (hereinafter referred to as PLU system), and the product code and the sales price are represented by the bar code, and the price is directly read. There is a system (hereinafter referred to as non-PLU system), and both are usually used together.

The PLU method is used when the same product has the same selling price, and the non-PLU method is used when the selling price is different depending on the weight even for the same product such as fresh food.

By the way, in a retail store such as a supermarket, a bar code is often printed on a product or a product having a label attached to the product is arranged at a store and then discounted by a time service or the like. In such a case, the PLU type product is
This can be dealt with by clearly indicating the price to be discounted to the product and correcting the stored contents of the selling price in the POS register, but in the product of the non-PLU system, the selling price is included in the bar code itself. It is necessary to re-attach the barcode label or use the input key of the POS register to input.

When relabeling with one of the conventional methods, the product at the store is temporarily pulled up and the label is issued again by the weighing and pricing machine, but the normal pricing work must be interrupted. , Once the store products are empty,
The fact that it is discounted cannot be identified on the label,
Time service has the disadvantage that you have to re-apply the normal label after the service time has passed,
This method is not widely adopted.

What is most often used at present is that a clerk attaches a discount sticker (for example, 100 yen discount for a certain product) to the product purchased at the store. Or write down the discounted price with a felt-tip pen, etc., and then at the time of payment
This is a method of inputting the correction amount with the key in the S register.

However, in the case of this method, there is a problem that the cashier operation becomes more frequent than usual, and the merit of simplifying the cashier operation, which is one function of the POS system, is lost.

(Object of the Invention) An object of the present invention is to perform a settlement in a POS register without manual operation when there is a price change after a bar code is displayed on a product in a POS system.

(Summary of the Invention) A bar code processing device of the present invention is a device for reading bar code data recorded in a bar code, a device for inputting discount information of a product, and a selling price after discounting from the read selling price. Comprising a controller having a calculation unit for calculating and a display unit for displaying the calculated selling price, and by inputting the barcode data into the controller, obtaining new barcode data from the barcode data. It is characterized by.

Further, the controller is provided with a printer to print new bar code data on the label.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of the present invention. As shown in the figure, a barcode scanner A for reading a barcode and a controller B are connected by a cable C. Controller B
Is provided with a key a, a display section b, a printer c, a calculation section d, etc. In addition to inputting various information from the key a,
Discount information related to the present invention is input. As the discount information, (1) x% is reduced from the list price of the product.

(2) The price of the product will be reduced by y yen.

(3) Reduce z yen uniformly.

Etc.

The controller B calculates the selling price after discount from the selling price read by the barcode scanner A, displays the selling price, and issues a new barcode label. In this case, the bar code label is the product code as it is, and only the price is corrected by the calculation result and printed.

FIG. 2 is a schematic block diagram of the present invention and corresponds to the block diagram of FIG. FIG. 3 is a flow chart showing the processing procedure of this embodiment.

As shown in FIG. 2 and FIG. 3, in the present invention, the bar code of the label attached to the discounted product is read by the bar code scanner A and input to the operation unit d of the microcomputer configuration of the controller. The calculation unit d calculates the post-discount selling price from the read selling price by using the discount information input in advance according to the above (1) to (3). Next, the read product code and the calculated selling price are displayed on the display section b, and the barcode is printed on the label, and this is overlaid on the label of the discounted product.

As a result, at the time of payment, the correction amount is input to the cash register for POS, which simplifies the register operation.

FIG. 4 is a schematic block diagram of an embodiment of the present invention.
In this embodiment, the controller is a cash register for POS, stores the discount information of the discounted product in the memory M of the cash register, and discriminates the discounted product when the bar code is read. To determine the selling price. Therefore, in this case, the label issuing device is unnecessary.

FIG. 5 is a flowchart showing the processing procedure of the second embodiment.

Next, this flowchart will be described.

(1) Check whether the barcode data is stored in the barcode scanner A (step P ₁ ),
If there is no data, then it is confirmed whether the key is on (step P ₂ ). If it is key-on, it is determined whether the registration processing of the data (step P _3).
If it is data registration processing, discount information is preset (step P ₄ ). If it is not the registration process, other key processes such as total calculation display and price correction are performed (step P ₅ ).

(2) If there is data in the process of step P ₁ , the bar code information is input and stored in a predetermined area of the memory (step P ₆ ). Next, it is determined whether the item discount or items (Step P _7), if the value引商article reads discount information of the commodity, to calculate displays a selling price value, net (step P ₈ ). This process is the first
The same procedure as in the above embodiment is performed. Subsequently, the selling price is cumulatively added (step P ₉ ).

In the above example, the bar code scanner A and the controller B are described as separate bodies, but the bar code scanner A, which is a bar code reading means, may be provided at an appropriate position of the controller B to be integrated. it can.

(Effects of the Invention) As described above, according to the present invention, when there is a price change after a barcode is displayed on a product in a POS system,
Since the settlement at the POS register can be performed without manual operation, and the new selling price can be displayed and a label with new bar code data printed can be issued, the effect of simplifying the cash register operation can be obtained.
