DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a POS (POIN DOWN OF 5 ALE) system having a discount processing function.

[Prior Art] Conventionally, as a POS system having a discount processing function, there is, for example, Japanese Unexamined Patent Publication No. 63-225897 ``Transaction Processing Device 0.'' This invention sets one discount rate for each product and registers the product. When a product code is input, the unit price and discount rate of the corresponding product are read out from the product code, and discount processing is performed for each product.

[Problems to be Solved by the Invention] However, the above-mentioned prior art has the following problems. There is a problem in that it takes a lot of time to change the discount rate on a daily basis or to change the discount rate for each product once set in one PLU file such as a time discount service. Additionally, there is a problem in that changing discount rates for many products tends to result in errors in data input.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and stores department information and discount status information for each product in a PLυ file, and stores a discount rate corresponding to the discount status information for each department in each terminal. A discount function that allows you to easily change the discount rate by simply changing the discount rate and discount parameters for each department in the terminal without changing the PLU file by storing the information and specifying the discount parameters. It provides a POS/Stem with
Ru.

[Means for Solving the Problems] FIG. 1 is a diagram showing the principle of the POS system of the present invention. In the figure, the PLO file 2 of the PLU file unit is a PLO file consisting of a product code, department number, price, and discount status information specifying one or more discount categories.
An LU record is stored for each product.

The department file 4 of the POS terminal stores a plurality of discount rates corresponding to discount categories that can be specified by the discount status information of the PLtJ file 2 in the middle of the department.

The discount data storage means 6 stores discount parameters that specify which of a plurality of discount categories is to be used.

The changing means 8 changes the discount parameter and discount rate depending on the situation.

The confirmation method IO selects the corresponding PLU from the PLU file unit according to the input product code of the purchased product.
Read discount status information in record and PO
The discount parameters are read from the discount data storage means 6 in the S terminal and the two pieces of information are compared to determine the discount category.

The discount rate reading means 12 reads the corresponding discount rate from the department file 4 according to the discount classification obtained from the determining means IO. Further, the selection means included in the discount rate reading means 12 is configured to select, when a plurality of discount categories are obtained from the confirmation means,
According to the obtained plurality of discount categories, several corresponding rI discount rates are read out from the department file, and one prespecified discount rate is selected.

[Operation] The confirmation means IO of the POS terminal reads the discount status information in the corresponding PLU record from the PLU file 2 according to the input product code of the purchased product, and also reads the discount parameters from the discount data storage means 6 in the POS terminal. When the discount rate reading means 12 compares both pieces of information and determines the category in which both pieces of information are set as the discount category, the discount rate reading means 12 extracts the discount corresponding to the discount category from the department file according to the confirmed discount category. Read the rate. Note that if there are a plurality of discount categories obtained, the numerical values of the obtained discount rates are compared to determine the discount rate of one pre-designated rank. Further, the discount rate determined can be changed by changing the discount parameter and the discount rate method using the changing means as needed.

As shown in Figure 8 (8), the department file of the present invention is composed of department records that store sales amounts, sales points, and discount rates corresponding to PLU Left's discount status information for each department. .

Furthermore, Figure 9 (A) shows the contents of the discount parameters.

Figure 5 is a schematic block diagram showing the configuration of the master 2. The mask 60 has the same function as the satellite 40 as well as a mask function for controlling the satellite 40 and the like. Keyboard 62, display 64, ROM 65, RAM 66, communication control unit 67, which are modules related to the mask function;
The main control unit 68 has the same structure or content as the satellite 40, so it is given the number ``wing''.

Below, discount processing in product registration by the satellite 40 will be explained with reference to FIGS. 2 and 7 to 9.

FIG. 2 is a flowchart showing the discount processing procedure. The discount process is stored as a registration process and a discount process program in the ROM 45, and is read out and executed by the CPU 48.

First, the method of product registration is determined (S2).

Below, S and numbers within 0 indicate step numbers. If it is a department registration, step S4 is performed, and if it is a single item registration, the process advances to step S6. In the case of single item registration, the product code affixed to the product is read by the scanner 41 of the terminal, and if the number is the number of items in a litter, the number is input from the keyboard 42 (S6). PLU via communication control unit 47
When the file unit 20 is accessed, the PLLI/code corresponding to the product code is read from the PLLI file 26. yg7 Figure (A) shows an example of a PLU file. The read product data such as product name, unit price, department, discount status, etc. are stored in the sales product transaction data storage area of the transaction data file shown in FIG. At the same time, the sales amount of PUL records,
The number of sales points is updated (S8). In this explanation, as shown in Figure 7, the division status is 3 (classification of I!, ■, m
It is possible to set The read product name, unit price, quantity, and amount are displayed on the display 44 and printed on l143.
printed on paper. (SI O). The amount, points, and their cumulative amount are stored in the total sales amount and total sales points area of the transaction data buff 7a of the RAM 46 (S1
2). From the department file in the RAM 46, the department record system 8 (A) to which the product belongs is read out. The cumulative amount of department sales amount, department sales points, etc. is calculated and updated (SI
4).

Next, it is determined whether the purchased product has a discount. First, the discount parameters in the RAM 46 are read out (SI6). Note that the discount parameters are normally set by the program mode and supervisor mode of the in-store processor, mask 60, and satellite 40 when the terminal is started up. The discount parameters, as shown in Figure 99 (A), are divided into the three categories 1. It can be set up to a maximum of 311 according to It and ■.

It is determined whether a bit for discounting is set in the discount parameter (S18). If the bit for discount is not set in any of the discount parameters, the process returns to step 536 without performing discount processing, and product registration is continued.

If the discount flag is set in the discount parameter,
For each of the discount status and discount parameters that have already been read out, a comparison is made to see if a bit is set for each category (S20). As a result, if the bit is set for only one of the discount parameters and discount status categories (S22), the process returns to step S36 without performing discount processing, and product registration is continued.

If the flag is set in both the discount parameter and discount status category (S22), a road discount process is performed in step S24. Indicators with flags set for both discount parameters and discount status (
The discount rate corresponding to the discount category (hereinafter referred to as discount category) is read out from the department record.

If the number of read discount rates is one (S26), the process proceeds to step 30 and the discount amount is calculated from the discount rate.

If there are multiple discount categories and multiple discount rates are read out (S26), for example, if the program is set to adopt the maximum value of the discount rates, the One maximum discount rate can be obtained from . (32g). The discount amount is calculated from the obtained maximum discount rate and monetary value 1 (S3
0). The calculated discount amount is displayed, printed, and stored in the transaction data storage area of the transaction data buffer (S32).
The cumulative discount amount is calculated and the total discount amount is updated (S
34).

Registration of one product is completed in the above manner.

The same process is repeated until registration of all purchased products is completed (S6 to 536).

When product registration is completed (S36), the total calculated from the total sales amount and the total discount amount is displayed and printed (
S38). When the customer's deposit amount and closing key are input from the keyboard 42, change is calculated. The deposited amount and change are displayed on the display 44, and printed on the note paper by the printing machine 43. Trailer line information is read out from the transaction data, printed on sheet paper, and then issued as a sheet (S40). When the issuance process is completed, the product date basis stored in the transaction data is cleared (342). One product transaction is completed as described above.

Next, a specific example will be explained using FIG. 7(B), FIG. 8(B), and FIG. 9(B).

It is assumed that the discount parameter is set to the state shown in FIG. 3 bl (discount designation corresponding to category ■) and a merchandise transaction is performed.

In this case, for the products with product codes 001001 and 001002, the bit is set in the discount status category ■, so the discount rate of the discount category ■ is applied to these products. These products (product code 001001.00100
In case 2), since the department number is 15, the discount rate of 5% of the discount category I of the department number 15 in the department file in FIG. 8(B) is applied. Product code 000001.00000
For the products of 2.001000.001QO3 and 001004, the bit is not set in the discount status category ■, so these products are excluded from the discount products.

Now, set the discount parameters as shown in Figure 3 b2 (categories ■, ■
In this case, the product with the product code 001001 has the discount status 11 ■ set, so the two categories summer and ■ have discount suitability. This product code 001001
The product has a department number of 15, so the discount category 1 for department number 15 in the department record. The discount rate of II is 5.10% (Figure 8 (B)), and if you decide to use the one with the larger discount rate, 10% will be retained. In addition, the product with product code 001002 has 2 bits only in discount category I.
Since no bit is set in the discount category ■, a 5% discount for the discount category ■ is applied. Product code 000001
．． The discount category for the product 000002 is ■, and the discount rate of category ■ for department number 1 is 10%. The product with the product code 001004 has a discount category ■, and a discount rate of 5% is applied to the category ■ of the department number 16.

As described above, the designation of the discount category can be changed by changing the discount parameter, so the discount rate can be changed more easily than changing it for each product.

In addition, when you reserve the discount parameter category ■ as the I-Egen category and set a bit in the discount category m of the Egen target product when creating the PLU file and start the bargain, set the discount parameter as shown in Figure 3. B3 condition! ! Assume that the setting is changed to (discount designation corresponding to category ■).

In this case, product code 001002.0 for department number 15
The product of 01003 is! Since the category ■ for Egeno is set, a discount of 30% is given for the category ■.

As mentioned above, by combining discount status and discount 1 < parameter, 1. <-gen, it is possible to easily change the desired discount rate such as time zone discount.

Although the satellite 40 has been described in this embodiment, completely similar processing is performed in the product registration of the master 60.

Further, although discount parameters are provided for each terminal in this embodiment, they may be provided for each department for more detailed discount processing.

Further, by providing a similar discount status in the department record, the discount processing number in the registration of each department can be similarly applied.

〔Effect of the invention 〕

As explained above, according to the PO8/Stem of the present invention, discount status information is stored for each product in the PLU file, and discount rates corresponding to the discount status information are stored in each terminal for each department, and discount parameters are stored. The discount rate for each product is determined using the discount parameters of the terminal and the discount rate of each department. You can change the discount rate for products.

(2) Since the discount rate can be easily changed in a short time, it is possible to easily implement a time discount service according to the sales situation.

(3) Discount rates can be changed on a department-by-department basis, and data related to discounts for many products can be changed with one input, resulting in less input of change data and, as a result, fewer input errors. It is also easy to check.
