Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a price lookup (hereinafter abbreviated as PLU) search method, and more particularly, to POS (Poi).
The present invention relates to a price lookup search method for searching the price (price) of a product read by a barcode in an nt of sales device.

[0002]

2. Description of the Related Art A bar code scanner, a key input device, and a display device are operated under the control of a memory containing a control program and a CPU operated by the control program contained in the memory to print or paste products. A POS device that reads a bar code with a bar code scanner to retrieve and output the price of a product is well known.

Conventionally, the product data read by a bar code in a POS device has been searched by accessing a PLU storage device attached to the POS device or separately connected.

[0004]

DISCLOSURE OF THE INVENTION The conventional PLU described above
In the search method, the bar code data of the product to be read by the bar code scanner of the POS device and the price data must be registered in the PLU storage device in advance. It has the disadvantage of having to register with the department.

Also, when a store introduces a product with a new bar code and performs a PLU search, the PL is used until the new bar code and price data are registered in the PLU storage unit of the POS device.
There is a drawback that U search cannot be performed.

[0006]

According to the method of the present invention, a POS device for retrieving product data indicating a product price read by a barcode from a PLU storage device that stores the product price specified by a barcode. In the PLU search method,
The POS device has an online control unit for controlling transmission / reception of barcode data and product data online.

Further, a CPU, a memory, a PLU master storage device for storing bar code data and product data, and an online control unit for controlling transmission and reception of bar code data and product data online are provided, and each control is performed on the memory. It has a host computer with a control program to perform.

Further, the host computer has means for registering the bar code data and the product data in the manufacturer of the product on which the bar code is printed and pasted in its own PLU master storage device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In this embodiment, two POs in two stores
This is the case with the S device. The host computer 10 in the PLU master management center uses the memory 1
1, a CPU 12, an online control unit 13, and a PLU master storage device 14. The PLU master storage device 14 includes bar code data 15 and product data 16 corresponding to the bar code data 15.

Next, as the POS device, the POS device 2 of the store A
0 and the configuration of the POS device 40 of the store B will be described. Each POS
The devices 20 and 40 include display devices 21 and 41 CPU2, respectively.
2, 42, key input devices 23, 43, online control units 24, 44, PLU storage devices 25, 45, memory 28,
48 and bar code scanners 30 and 50 are provided. PLU
In the storage devices 25 and 45, bar code data 26 and
46 and product data 27, 47 are stored. Each PO
Control programs 29 and 49 are provided on the memories 28 and 48 for controlling the operation of the S device.

There are manufacturers A and B who manufacture products with a bar code printed or attached, and stores A and B sell the products of the manufacturers A and B, respectively.

Next, the operation will be described. In the host computer 10 of the PLU master management center, the barcode data of the products manufactured by the barcode product manufacturers A and B and the product data are registered in the PLU master storage device 14. At the PLU master management center, the bar code data and product data of the bar code product manufacturers A and B are added to and updated in the PLU master storage device 14 of the host computer 10. In the POS device 20 of the store A, the PO
If the PLU in the S device is used for the first time, P
No bar code data or product data is registered in the LU storage device 15. Therefore, the POS device 20 of the store A
The online control unit 24 and the online control unit 13 of the host computer 10 are connected by a communication line.

First, the POS device 20 of the store A reads the bar code with the bar code scanner 30. For the read barcode data, the barcode data 26 in the PLU storage unit 25 is searched. However, since no bar code data is registered in the PLU storage unit, the read bar code data is transferred from the online control unit 24 to the host computer 10. Host computer 10
Then, the bar code data 15 in the PLU master storage device 14 is searched based on the bar code data received from the online control unit 13. The product data obtained by searching the bar code data 15 is registered in the PLU storage unit 25 of its own, and the sales process is performed.

Similarly, for the next product, first, after searching the bar code data 26 in its own PLU storage unit 25, the product code for which the bar code data is not registered is returned to the host computer 10, and the product obtained is obtained. Data will be registered in 25. Already once in the POS device 20, PLU
When the barcode of the product registered in the storage unit 25 is read, the PLU storage unit 25 is searched first, and the sales process is performed from there. In the POS device 20 of the store A, if the bar code read by the bar code scanner 20 is not registered in its own PLU storage unit 25, and is also not registered in the PLU master storage unit 14 of the host computer 10, In the POS device 20 of the store A, P
The LU storage unit 25 registers the bar code data and the product data of the product, and the online control unit 24 transmits the bar code data and the product data to the host computer 10. The host computer 10 registers the bar code data and product data received from the online control unit 13 in the PLU master storage device 14.

Next, when the POS device 40 of the store B operates for the first time, as in the case of the store A, the online control unit 44 of the POS device 40 and the online control unit 13 of the host computer 10 are connected by a communication line, PLU similar to A
Search and register in the PLU storage unit. Here, since the bar code of the product registered in the store A is registered in the PLU master storage device of the host computer 10 in the store B, there is no need to register it in the store B, and Can be used for PLU search. Similarly, in the POS device 40 of the store B, the PLU storage unit 4
The bar code data and the product data registered in No. 5 can be used in the store A. Further, the host computer 10 of the PLU master management center registers new bar code data and product data of the bar code manufacturers A and B in the PLU master storage device 14, so that the POS device 20 of each of the store A and the store B is registered. , 40, the PLU can be searched without registering the bar code data and the product data of the new product at the bar code product manufacturers A and B in the PLU storage units 25 and 45 of each POS device.

[0017]

As described above, according to the present invention, the host computer having the PLU master storage device is used, the barcode data and the product data of the barcode product manufacturer are registered in the host computer, and the online data is stored in the POS of each store. By having a control unit and means for transmitting and receiving bar code data and product data to and from the online control unit of the host computer, the store installs the POS device, and the PLU is installed.
Even if an attempt is made to search, there is an effect that the PLU search can be performed without registering the barcode data and the product data in the PLU storage section of the POS device.

Further, when performing PLU search for a new multi-item bar code, there is an effect that the PLU search can be performed without registering bar code data and product data of all new products.
