Abstract

PURPOSE:To prevent improper use of a coupon ticket by subtracting the number of commodities corresponding to identification code when said code indicated on the coupon ticket is inputted and prohibiting discounting when the number reduced to 0. CONSTITUTION:The code of a coupon is stored in a registering buffer 44 in an RAM4 and the amount of money of the coupon is stored in a register 45. Then, a manufacturer code buffer is searched to judge whether inputted manufacturer code is registered or not. If registered, the counter of a memory area corresponding to the code is made -1. If counted value of the counter 42 is not minus, the amount of money of the coupon is displayed on a display 5, and the amount of money of the coupon is printed by a printer 6. Further, the amount of money of coupon stored in the register 45 is subtracted from the total amount of money of the memory area 42. Error processing is performed when counted valu of the counter 42 reduced to minus.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an electronic cash register (hereinafter referred to as an ECR).
In particular, it relates to ECR in which when a customer uses a coupon (to purchase a product), a certain amount is discounted and data regarding the product is registered.

Description of the Prior Art Conventionally, coupons for specific products have often been sold at NI.

This coupon will be sent to R only when the customer purchases a product from the manufacturer. ml - Used for a service that provides a discount of a certain amount for customers who purchase products from a manufacturer.

Therefore, when a customer brings multiple coupons, products from the same manufacturer will be sold at a discount corresponding to the WzK of the coupons. but,
Some customers may use such Nari-Pon tickets to commit fraud such as purchasing products from other manufacturers and receiving discounts.

In such cases, fraud can be prevented by checking whether the manufacturer that issued the coupon and the manufacturer of the product purchased by the customer are the same or old. However, in supermarkets, etc., there are many products handled and many customers, so it is not easy to confirm whether the same manufacturer C is available, and the disadvantage is that it takes a lot of effort to register products. Ta.

Purpose of the Invention Therefore, the main purpose of the present invention is to provide an ECR that can register data related to a product only when the product of the same manufacturer as the coupon ticket is purchased.

Structure and Effects of the Invention The present invention can be summarized as follows.
, When the identification code of J@ product is input, that identification code and &! It is determined whether the identification code matches the identification code stored in the storage means, and if there is a match, the number of products stored in the storage means corresponding to the identification code is increased and displayed on the coupon. When an identification code is input, if the identification code matches the identification code stored in the storage means, the number of 1'+5 items stored in the storage means corresponding to the identification code is reduced to 8. ★The number of products is O
If it becomes ^1] It is configured to prohibit registration for first archery.

However, according to 11J of this issue, the number of coupons or the identification displayed on the coupons is less than the number of products with the same coat as the coupon. Since the discount can be applied to the prefecture thereafter, discount sales are prohibited even if products with different identification codes are purchased, and it is possible to effectively prevent coupons from being used in an unauthorized manner.

This invention will be explained in more detail with reference to the examples shown in the first and second sections.

Next (this invention with reference to Figures 1 to 6)
(I will explain the specific operation of the example.) When registering a product, iBerator enters the small code in Figure 4.
From near book-22 to human power 9-ru, "] LU key 2
Operate 41. Shown in Figure 4! l': In 1-1-, the first 24 and 1 is a code that does not represent the product registration of 8t, and the 33rd to 7th digits are the identification code.
A creator Ko)! The 8th to 12th digits indicate the price of each item, and the last digit indicates t.
,,i15 After inputting hood from the numeric keypad 22 according to the key operation procedure shown in FIG. 15, the PLtJ key 241 is operated. In the code shown in Figure 5, C1 is a code that represents the first two digits of the IJ coupon, the 183rd to 7th digits indicate the manufacturer's second code as an identification code, and the 84th to 10th digits indicate the item family number. The 11th and 12th digits indicate the coupon amount or discount amount,
Please check the last digit of ``F''.

First, when the operator registers the product according to the key operation h = + in Fig. 4, CPU 1 registers the product with
), and the key is 7-key 22.
Determine whether there is human power C from 4 If there is human power C from numeric keypad 22, store the input number data in number buffer (NBU) 44, and then store it before storage Vi46.
Set the flag (F K N ). Repeating this operation, the first button shown in FIG.
Enter the numerical data from the digit to the 13th digit to the number of strokes Baranoa 44
Store in.

Next, when the operator operates the PLU key 241,
The CPU 11 determines that the PLIJ key 241 has been operated, and determines that the flag FKN has been set. And then, the first two who were blown away by the late Bano 744.
Determine whether the number of digits (1#1 or 198 represents a coupon or not) is present. Ku/j
The F'LU file 47 shown in FIG. 3 is reached in accordance with the input "-1-". Then, it is determined whether or not the same P1U code exists in the PLU file 47, and if it exists, the manufacturer code buffer is reached and whether the same manufacturer code exists 4. Determine whether or not. If it does not exist, the manually entered manufacturer code is registered in the storage area 41 as a new code. If the same i! ! ! If the maker code exists, invert the corresponding counter by +1. Then, the CPU 1 reads out the single item price data from the PLU file 47 corresponding to the input PLU code, displays it on the display 5, and prints out the price etc. using the printer 6. Furthermore, the unit price data of the PLU is cumulatively added to the storage area 43, and the process returns to the -C initial state.

By repeating this operation, the operator registers the products purchased by the customer.

Therefore, each time a product with the same manufacturing code 1 is registered in the manufacturer code buffer, its counter 42 is
will be added to Korea.

If the customer presents a coupon with the purchase of the product, enter the "-" displayed on the coupon according to the key operation procedure shown in FIG. In other words, the tarpon code shown in FIG. When the p-t-u key 241 is operated, it is determined that the flag FKN is set, it is determined that the first digit of the input [-] code represents a coupon, and the number buffer is The input manufacturer code is stored in the second and third digits from the bottom stored in register 44 (directly, evc stores the coupon amount in register 45, and stores manufacturer code buffer in register 45). Determine whether or not it has already been registered.

If there is a corresponding manufacturer code, the counter in the storage area 42 corresponding to that code is decremented by 1. Then, it is determined whether the count value of the counter 42 is 0 or negative. If it is not negative, the coupon amount is displayed on the display 5, and the coupon amount is printed by the printer 6. The coupon amount stored in the register 45 is subtracted from the total amount in the area 42. When codes are input for the number of coupons presented by the customer,
When the above-described operation is repeated and the count value of the counter 42 becomes negative, error handling is performed. Therefore, even if a customer tries to request a discount by presenting a coupon code for a product that does not have the same manufacturer code as the coupon ticket, an error will be processed, thereby preventing fraudulent transactions.
