If country code 110 is determined to be 49 (ie Japan)
If it is determined that the product manufacturer code 120 of the JAN code is read, the process proceeds to S5. Further proceeding to S6, among the PLU masters divided and stored based on the product maker code 120 read in S5,
It is determined which divided PLU master. That is, n
MF # 1, MF # 2, MF # 3 ...
..Which split PL in the split PLU master of MF # n
It is to judge whether it is a U master. Then, in S7, the number of the divided PLU master determined in S6 is read, and in S8, a search is performed in the corresponding divided PLU master. As a result, information such as the unit price, product name, department code, and discount rate is read in S9, and in POS terminal 2
Is displayed on the display device and the receipt is issued in S11. Then, in S12, a series of operations of the POS system 1 ends.

If the country code 110 is not 49 in S4, the process proceeds to S13. In S13, if the JAN code is a standard type with 13 digits and the country code 110 is 04, or if the JAN code is a shortened type with 8 digits and the country code 110 is 0, Since it is in-store marking, according to each standard, P
LU processing is performed. In-store marking is performed in the case of perishable foods, etc., and is a type that is printed with a specified code after weighing.

In S14, the country code 110 is 20-2.
Since 9 is a reserve of EAN, processing is performed by EAN or the like, or it is excluded from the target of the PLU master.

It can be set to # 8, and each file can be set to about 20,000. And the main product master, JAN
Code, EAN code, UPC code, in-store (P
It is also possible to sequentially transfer the files in the order of (LU) code to the PLU master and create a file with the specified number of files.

In this case, the start code and the end code can be written in each master management table when the file is created. Then, PLU processing and maintenance are performed in the management table. Further, the code number of the clearance between each master can be registered in a spare file.

Further, the total number of records of all PLU masters is divided by the number of files to obtain the average number of records,
It is also possible to compare this with the number of records stored in each of the product masters divided into a plurality of pieces, and to generate an alarm signal when they are separated by a certain amount or more. In the present embodiment, an alarm is issued when the amount is over 20% or under 20%, but it can be changed as appropriate. And FIG.
It is also possible to display as an indicator, as shown in. The user can make appropriate appropriate allocation based on these displays and warnings.

In the PLU-MF, when the number of set records exceeds, PLU-MF # 99 is automatically set.
It can also be configured to write to. Furthermore, the corresponding P
PLU-MF is automatically used even if LU-MF does not exist.
You may write in # 99 and may perform PLU processing again.
