FIG. 5 is a schematic block diagram showing the configuration of the master 60. The master 60 has a master function of controlling the satellite 40 and the like in addition to the same function as the satellite 40. Keyboard 62 and display 6 that are modules related to the master function
4. The ROM 65, the RAM 66, the communication control section 67, and the main control section 68 have different numbers from those of the satellite 40 because the configuration or the contents are different.

Hereinafter, the discount processing in merchandise registration by the satellite 40 will be described with reference to FIG. 2, FIG. 7 to FIG.

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

First, the registration method of the product registration is determined (S2).
Hereinafter, S and numerals in parentheses indicate step numbers. If the registration is a department registration, step S4 is performed. If the registration is a single item, the process proceeds to step S6. In the case of single item registration, the product code attached to the product is read by the scanner 41 of the terminal,
If the number is plural, the number is input from the keyboard 42 (S6). The PLU file unit 20 is accessed via the communication control unit 47, and a PLU record corresponding to the product code is read from the PLU file 26. Fig. 7 (A)
Shows an example of a PLU file. The read product data such as the product name, unit price, department, and discount status are stored in the first RAM 46.
It is stored in the sales merchandise transaction data storage area of the transaction data buffer shown in FIG. At the same time, the sales amount and sales points of the PUL record are updated (S8). In this description, as shown in FIG. 7, the discount status can be set in three categories I, II, and III. Product name, unit price, quantity,
The amount is displayed on the display 44, and is printed on the receipt paper by the printing machine 43. (S10). Amount, points and their cumulative amount are R
It is stored in the total sales amount and total sales points area of the transaction data buffer of AM46 (S12). The department record to which the product belongs is read from the department file in the RAM 46 (FIG. 8A). Cumulative amounts such as the section sales amount and the section sales points are calculated and updated (S14).

Next, it is determined whether or not the purchased product has a discount. First, the discount parameter of the RAM 46 is read (S16). The discount parameter is usually set by the program mode and the supervisor mode of the in-store processor, the master 60 and the satellite 40 when the terminal is started. As shown in FIG. 9A, up to three discount parameters can be set in accordance with the three sections I, II, and III of the PLU record (FIG. 7A).

It is determined whether or not 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 proceeds to step S36 without performing the discount process,
Product registration continues.

If the discount flag is set in the discount parameter, a comparison is made as to whether a bit has been set for each category for each of the discount status and the discount parameter that have already been read (S20). As a result, if the bit is set in only one of the discount parameter and the discount status (S22), the process proceeds to step S36 without performing the discount process, and the commodity registration is continued. If the flag is set in both the discount parameter and one of the discount status categories (S22), the process proceeds to step S24 to perform a discount process. A discount rate corresponding to a category in which a flag is set in both the discount parameter and the discount status (hereinafter referred to as a discount category) is read from the department record. If one discount rate is read (S26),
Proceeding to step 30, the discount amount is calculated from the discount rate. When there are a plurality of discount categories and a plurality of discount rates are read out (S26), for example, if the program is set to adopt the maximum value of the discount rates, the discount rate is selected from among the plurality of discount rates. You get one maximum discount rate. (S28). The discount amount is calculated from the obtained maximum discount rate and amount (S30). The calculated discount amount is displayed, printed, and stored in the transaction data storage area of the transaction data buffer (S32). The total discount amount is calculated, and the total discount amount is updated (S34).

 One product registration is completed as described above.

The same process is repeated until the registration of all the purchased commodities is completed (S6 to S36). When the 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 the closing key are input from the keyboard 42, a change is calculated. The deposit amount and the change are displayed on the display 44, and are printed on the receipt paper by the printing machine 43. Trailer line information is read from the transaction data, printed on receipt paper, and issued as a receipt (S40).
When the issuing process is completed, the product data buffer stored in the transaction data is cleared (S42). One commodity transaction ends as described above.

Next, specific examples are shown in FIG. 7 (B), FIG. 8 (B),
This will be described with reference to FIG.

Assume that the discount parameter is set to the state shown in FIG. 9 b1 (discount designation corresponding to the category I) and a commodity transaction is performed.

In this case, the products of the product codes 001001 and 001002 have their bits set in the category I of the discount status.
The discount rate of discount category I is applied to these products. Since these products (product codes 001001 and 001002) have a department number of 15, a discount rate of 5% for the discount category I of the department number 15 in the department file of FIG. 8B is applied. Product code
Since the bits of 000001, 000002, 001000, 001003, and 001004 have no bit set in the discount status category I, these items are excluded from the discount items.

Now, the discount parameter is changed to the state shown in Fig. 9 b2 (Category I, II
It is assumed that the setting is changed to (discount designation corresponding to).

In this case, since the discount statuses I and II are set for the product with the product code 001001, the two categories I and II have discount suitability. Since the product with the product code 001001 has a department number of 15, the discount rate of 5 or 10% (FIG. 8 (B)) of the discount category I or II of the department number 15 of the department record corresponds to the larger discount rate. If you decide to use, 10% will be applied. Note that the product of the product code 001002 has a bit only in the discount category I, and no bit is set in the discount category II, so that a discount of 5% of the discount category I is performed. The products with the product codes 000001 and 000002 have a discount category of II, and a discount of 10% is provided for category II of category II. The product with the product code 001004 has a discount category of II and a category number of 16
The discount rate of II is 5%.

As described above, since the designation of the discount category can be changed by changing the discount parameter, the discount rate can be easily changed as compared with the case of changing for each product.

In addition, the discount parameter category III is reserved as a bargain category, a bit is set in the discount category III of the bargain target product when creating a PLU file, and when the bargain is started, the discount parameter is set in FIG. 9 b3. Condition (Category III
It is assumed that the setting has been changed to (specify the discount corresponding to).

In this case, since the products with the product codes 001002 and 001003 of the section number 15 have the bargain category III set, the category III is discounted at a discount rate of 30%.

As described above, by combining the discount status and the discount parameter, it is possible to easily change a target discount rate such as a bargain or a time zone discount.

As described above, the satellite 40 has been described in the present embodiment, but exactly the same processing is performed in the merchandise registration of the master 60.

Further, in this embodiment, the discount parameter is provided for each terminal. However, a more detailed discount process can be performed by providing the discount parameter for each department.

Further, a similar discount status is provided in the department record, and the same can be applied to the discount processing in the registration of each department.

〔The invention's effect〕

As described above, according to the POS system of the present invention, the discount status information is stored for each product in the PLU file, the discount rate corresponding to the discount status information is stored in each terminal in each unit, and the discount parameter is set. Since the discount rate is specified and the discount rate of each product is determined by the discount parameter of the terminal and the discount rate of each department, (1) Many products can be prepared in a short time without requiring much time as in the change of the PLU file. The discount rate can be changed.

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

(3) Since the discount rate is changed for each department and data relating to discounts of many commodities are changed by one input, the number of input of changed data is small, and as a result, input errors are small.
Also, checking can be easily performed.
