JPH087005A - Single product registration method and pos terminal equipment - Google Patents

Abstract

PURPOSE:To reduce the number of product masters for retrieving PLU in a POS terminal equipment. CONSTITUTION:A bar code numeric string is divided into the part of a code becoming the key of retrieval using a price look up table 4 and the part of other codes showing detailed information on a single product. Thus, only one of the products whose unit prices and product names are the same is set as the product master. A bar code which is read by a bar code scanner 1 is stored in an external storage device 3 with other sales information. Then, the single product is more minutely managed by the remained codes which are not considered to be the keys at the time of retrieval.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single item registration method by reading a bar code attached to a product and a POS terminal device.

[0002]

2. Description of the Related Art Conventionally, in a POS (point-of-sale information management) terminal device that performs a single item registration by reading a bar code attached to a product, all the bar code numeric strings are defined as product codes, and PLU (Price Look) is used. up)
Method to obtain product information such as unit price and name by searching (P
LU method) and a registration method (non-PLU method) that does not require a PLU search by adding a department code or unit price in a bar code numerical sequence and does not have a product master.

[0003]

In the method of performing PLU search, it is necessary to have a master table for all products in a table.
In particular, when only the colors and sizes of clothing differ, many product masters must be managed compared to the number of product types handled.

On the other hand, in the method that does not perform the PLU search, since there is no product master,
Although the department and price can be obtained, there is no information such as the product name and tax classification such as external tax / internal tax / tax exemption, and the name and tax classification of the department to which the user belongs are used for sales registration. Therefore, there is a problem that fine grain registration cannot be performed for each individual item.

An object of the present invention is to provide a single-item registration method which can reduce the number of product masters while performing PLU search.

Another object of the present invention is to provide a POS terminal device for implementing the above method.

[0007]

According to the method for registering a single item of the present invention, in a POS terminal device having a bar code scanner for reading a bar code attached to a product and a product master table, a preset bar code is set. It is characterized in that the PLU search is performed on the product master table using only the digit position. In this case, detailed information of a single item is included in the remaining digit positions of the barcode.

The POS terminal device of the present invention comprises a bar code scanner for reading a bar code attached to a product, a product master table, an external storage device for storing the bar code and sales information read by the bar code scanner,
A control device for performing a PLU search for a product master table by using only a preset digit position in a bar code read by a bar code scanner and performing a single product registration.

[0009]

[Function] By dividing the barcode numeric string into the code part that is the key for the search using the price lookup table and the other code part that represents the detailed information of a single item, the unit price and product name are the same. 1 for some products
Only one is set as a product master. On the other hand, the bar code read by the bar code scanner is stored in an external storage device together with other sales information, and finer individual item management is performed by the remaining codes that are not considered as a key at the time of retrieval.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a POS terminal device of the present invention. Reference numeral 1 is a bar code scanner for reading a bar code attached to a product, 2 is a printer for printing sales receipts, 3 is an external storage device for storing sales information, and 4 is an SRAM in which a price lookup table 5 is stored. , 6 are control devices.

FIG. 2 shows the code structure of the bar code according to the present invention. 1 indicated by barcode 11
Of the three-digit code, the leftmost first digit "2" represents in-store marking, which is distinguished from the conventionally used barcode. The second digit that follows represents the length of the code part that is the target of the PLU search, that is, "6" is the 6th digit from the third digit to the eighth digit, "100123" is P.
It is a key for LU search. The "X" in the rightmost digit is a check digit. Of the remaining barcode numerical value sequence not used as a key for PLU search, the part "0102" excluding the check digit is used to represent detailed information of a single item such as color and size of clothing.

Next, the details of the operation of this embodiment will be described with reference to FIG. Note that FIG. 3 shows the control device 6
3 is a flowchart showing the operation of FIG.

The bar code numerical value sequence read by the bar code scanner 1 is sent to the control device 6. Control device 6
Receives the barcode numerical value sequence (step S1), determines whether the first digit on the left side of the numerical value sequence is "2" (step S2). If it is "2", the value of the second digit is read (step S3). In this case, since it is "6", the numerical sequence "100123" of the third to sixth digits is fetched (step S4), and the price lookup table 5 is searched using this as a key (step S5).

Sales are registered using the single item information such as the unit price and the product name obtained by searching the table 5 (step S6), and the sales receipt is issued from the printer 2 (step S7). Further, the read barcode is stored in the external storage device 3 together with the sales information.

Next, the control device 6 extracts from the portion (stored in the external storage device 3) excluding the check digit of the remaining bar code numerical value sequence not used as a key at the time of retrieval, for example, the color of clothing. Read detailed information on individual items such as size and size.

As described above, it is possible to register a single product by setting only one product having the same unit price and the same name as a master, and to determine which kind of product is sold from the outside. The sales information stored in the storage device 3 can be used for discrimination, and fine grained individual item management can be performed.

On the other hand, if the first digit on the left side of the read bar code is not "2" in step S2, PLU search is performed using all the bar code numerical value columns as keys (step S9), and individual products are registered. This is similar to the conventional method.

[0019]

As described above, according to the present invention, the PLU search is performed by using a part of the read bar code as a key, the single item registration is performed, and the remaining number string includes the detailed information of the single item. Therefore, there is an effect that the number of product masters can be reduced, maintenance can be facilitated, and this can be realized with a small memory capacity while performing the fine-grained individual product registration equivalent to that of the conventional one.
