Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sales data processing device such as an electronic cash register, a POS system or the like.

[Conventional technology]

At a retail store, issue discount coupons with certain discount conditions for sales promotion, such as discount conditions that become effective when a certain number of target products are purchased at the same time and consume those discount tickets. When a person purchases a product, it is given a predetermined discount when it is used.

Conventionally, it is possible to set a certain discount amount for each product in advance, and if you register the sales of that product, you can realize an electronic cash register that calculates the discount amount for each product and calculates the sales amount. However, various discount conditions, for example, it is possible to determine whether or not the target product has been purchased by two or more or three or more, and a predetermined discount can be provided is realized. Didn't. Therefore, when giving a discount with a discount ticket, the cashier must check if a certain number of products subject to the discount ticket have been purchased at the end of one registration and perform the discount operation. There wasn't.

[Problems to be solved by the invention]

As described above, when the checker itself checks whether the discount conditions such as a discount ticket are satisfied at the end of one registration, not only the checker's burden is increased but also the time required for one registration operation becomes long. However, there is a problem that the efficiency of the registration process is reduced. Therefore, there is also a problem in that different discount conditions cannot be set for various product groups or various discount tickets cannot be issued due to problems in processing efficiency.

The object of the present invention is to determine whether or not the content of one registration satisfies the coupon condition of the presented coupon when the customer presents the coupon, and if it is determined that the coupon condition is satisfied, , The coupon unit price corresponding to the coupon is to be discounted from the sales amount.

[Means for solving problems]

 The means of the present invention are as follows.

The setting means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) sets the coupon condition and the coupon unit price corresponding to the coupon code. The storage unit 2 cumulatively stores the number of registered products sold for each coupon code.

The coupon ticket reading means 3 includes, for example, an optical barcode reader, and reads the coupon code of the coupon ticket presented by the customer.

The determination unit 4 determines whether or not the number of sales for each coupon code corresponding to the coupon code read by the coupon ticket reading unit 3 satisfies the coupon condition.

The discount means 5 subtracts the coupon unit price corresponding to the coupon code from the sales amount when the determination means 4 determines that the coupon condition is satisfied.

[Action]

 The operation of the means of the present invention is as follows.

The coupon condition (for example, the number of sales is 2 or more) and the coupon unit price (for example, $ 0.10) are set in the setting means 1 in correspondence with the coupon code, and when the sales data of the product is registered, the product is targeted for the coupon. If it is a product, the number of sales of the registered products is cumulatively stored in the storage means 2 for each coupon code.

When the customer presents the coupon, the coupon reading means 3 reads the coupon code of the presented coupon. The discriminating means 4 discriminates whether or not the sales quantity for each coupon code corresponding to the coupon code read by the coupon ticket reading means 3 satisfies the coupon condition, and the determining means 4
When it is determined that the coupon conditions are satisfied, the discount means 5 subtracts the coupon unit price corresponding to the coupon code from the sales amount.

Therefore, when the customer presents the coupon ticket, the checker does not need to check whether or not the contents of one registration satisfy the coupon conditions corresponding to the presented coupon ticket, and the checker's burden is reduced and the coupon is reduced. The checker does not need to input the coupon unit price corresponding to the ticket, and the efficiency of the sales registration process can be improved.

〔Example〕

An embodiment will be described below with reference to FIGS. 2 to 9.

FIG. 2 is a circuit block diagram of an electronic cash register (ECR). CPU21 processes data input / output, writes to RAM24,
It is a central processing unit that performs read processing, control of various operating procedures, and the like, and executes a control program stored in the ROM 22 connected to the CPU 21 to perform those processing. The input unit 23 is a key switch for switching the operation mode to registration, inspection, settlement, setting, etc., a numeric keypad for entering numerical values such as the number of sales, a code number for each product, a department key used for product category classification, and Close the registration "Current /
It is composed of function keys such as "deposit" key and a scanner for reading the bar code given to each product, and the signal from these keys or the scanner is CPU21.
Is output to. The CPU 21 has a RAM 2 having a coupon value table and a coupon registration buffer, which will be described later.
4 is connected.

In addition to this, when the PLU code etc. determined for each product is input by the scanner of the input unit 23, the PLU code is transmitted to the master ECR via the inline line 25, and the unit price data etc. which are further transmitted are received. Transmission unit 2
6, a display unit 27 that displays the amount of sales, the number of units sold, etc., a printing unit 28 that prints those data on a receipt, and a drawer unit 29 that stores cash that opens when a closing key for one registration is operated. .

FIG. 3 is a block diagram of a POS (Point Of Salese) system. The electronic cash register (ECR) 31 of the master and the slave ECRs 32 and 33 are connected by the inline line 25, and the master ECR31 of the PLU file (Fig. 4) responds to the inquiry of the unit price from the slave ECRs 32 and 33. Read the corresponding unit price data and output the unit price data to the slave ECR. Each ECR has an OBR (Optical Bar Code Reader) 34, 35, 36, which can read the bar code attached to each product and register the product and a coupon ticket described later.

Next, FIG. 4 is a diagram showing the structure of a PLU (price lookup) file stored in the master ECR 31.
The PLU file has a storage area a ₁ for storing a PLU code preset for each product, an area a ₂ for storing the unit price,
Area a ₃ for storing a flag (which will be described later) indicating which coupon the product is a target product, and each slave
An area a ₄ for storing the total number of units sold in the ECRs 32 and 33 and an area a ₅ for storing the amount of sales are provided.

In response to the unit price inquiry from each slave ECR 32, 33, the master ECR 31 reads out the corresponding unit price data of the PLU file from the PLU code sent and sends it to the slave ECR which made the inquiry.

Further, FIG. 5 is a diagram showing the structure of a terminal memory file for storing the sales data of each ECR. As shown in the figure, the terminal memory file has a storage area B for storing subtotals at the time of sales registration, storage areas b ₁ , b for storing sales quantity and sales amount for each department.
_2. Areas C and D for storing the number of cash sales and the amount of cash sales are provided.

When registering sales, each ECR accumulates the number of units sold, the amount of sales, etc. for each department to which each product belongs, and further calculates the cumulative total sales and stores them in each terminal memory file.

Further, FIG. 6 is a diagram showing a bar code structure of a discount coupon. As shown in the figure, bits D ₁ and D ₂ are set to a code “05” indicating that they are coupons, bits D _{3 to} D ₇ are supplier (maker) codes, and bits D _{8 to} D ₁₀ are A family code that is set for each manufacturer to classify products, bits D ₁₁ and D ₁₂ are discount codes indicating discount amounts, coupon types, etc., and bit D ₁₃ is a check digit for checking reading errors.

Further, FIGS. 7A and 7B are diagrams showing the configurations of the coupon value table of RAM and the coupon registration buffer. In the coupon value table of FIG. 7 (a), a supplier code for each coupon ticket, an area e ₁ for storing a family code, and a product for which the coupon ticket is targeted are stored.
For example, an area e ₂ for storing the type of discount condition, that is, a coupon type such as whether the discount is valid when two or more are purchased, and an area e ₃ for storing the discount amount (coupon unit price) of the coupon ticket. Are provided in plurality. Then, codes of usable coupons and the like are preset in the storage areas e _{1 to} e ₃ .

Further, in the coupon registration buffer of FIG. 9B, the supplier code for each coupon ticket, the area d ₁ for storing the family code, and the cumulative total of the sales quantity of the products targeted by the coupon ticket are stored as described above. A plurality of regions d ₂ are provided respectively.

Next, the operation of the ECR32 having the above configuration is shown in FIG.
The operation will be described with reference to the operation flowchart of (b) and the operation example of FIG.

FIG. 8A is a flowchart showing the processing operation of sales registration for each product.

In the slave ECR32, when the barcode of the product is read by the scanner (OBR35) and sales registration is performed, the read barcode (PLU code) is sent to the master ECR31 to inquire the unit price of the product. Then, on the master ECR31 side, the unit price corresponding to the sent PLU code is read from the PLU file, the unit price data is sent to the slave ECR32 that made the inquiry, and the content of the flag set for each product, that is, the target coupon. Send data such as supplier code, family code, coupon type, etc., which indicates the ticket type, to the slave ECR32. On the slave ECR 32 side, the sent unit price data is temporarily stored in a sales accumulation buffer (not shown) of the RAM 22, and is displayed on the display unit 27 as the unit price of the product, and is printed on a receipt or the like (process S ₁ ).

An example of these operations is shown in FIG. 9 (1). As shown in the figure, when the barcode of the product is scanned and the product with PLU code "0001" is registered, the unit price is "$ 1.
00 ”is displayed and is printed on the receipt.

Next, it is determined whether the coupon code (supplier code, family code, code indicating the coupon type, etc.) is set for the product based on the content of the sent flag (process S ₂ ), and the coupon code is set. without it moves to process S _6, normal registration, executes the printing process.

On the other hand, when the coupon code is set, the area d ₁ storing the coupon code in the coupon registration buffer is searched (process S ₃ ) to determine whether the same coupon code has already been set. (Processing S ₄ ). When the coupon code that makes the registered product a symmetrical product is already set (process S ₄ YES), the sales quantity in the storage area d ₂ of the coupon registration buffer is incremented by 1 (process S ₅ ), and the process S ₆ is performed. The normal registration process, that is, the unit price of the product,
Stores the number of sales, etc. in the terminal memory file and displays and prints the sales data.

On the other hand, when the same coupon code is not set in the coupon registration buffer (process S ₄ NO), the coupon code of the product is newly set in the coupon registration buffer (process S ₇ ), and further, as the sales quantity. "1" is set (processing S _8). After that, the same registration process as above
Execute S ₆ to finish the registration of one product.

The above processing is executed by scanning the bar code every time sales are registered.

Next, the operation when the coupon ticket is scanned after the PLU registration will be described with reference to the flowchart of FIG.

First, the coupon value table is searched from the read coupon code, and the discount amount (coupon unit price) by the coupon ticket, the coupon type, etc. are obtained (process S ₉ ). Further search the coupon registration buffer (process S ₁₀ ),
It is determined whether the same coupon code as the registered coupon is set (process S ₁₁ ). If the same coupon code is not set, the coupon registration is regarded as an error and the registration is invalidated.

If the same coupon code is set, (Process
S ₁₁ YES), then determine the type of registered coupon (process S ₁₂ ), and for BUY 1 type, that is, for discounting when one or more products subject to the coupon are purchased, sales number of coupon registration buffer Mr. -1 (processing S _13), executes the coupon registration processing (processing S _16), coupon bar display and print the discount amount calculated from the flow table, the sales total amount of money the discount amount Subtract from.

On the other hand, if the registered coupon ticket is BUY2 type, that is, the coupon is discounted when two or more products that are the target of the coupon ticket are purchased, similarly, first, the memory is stored corresponding to the coupon code in the coupon registration buffer. is checked sales quantity is, to determine whether sales quantity is two or more (processing S _14). If the number of sold products is not two or more, the coupon registration is invalidated. On the other hand, when the number of sales is two or more, the number of sales is decremented by 2 (process
S ₁₅ ), the coupon registration processing S ₁₆ is executed in the same manner as described above, and a discount is made according to the discount amount obtained from the coupon value table.

That is, after registering a product having a PLU code as shown in FIGS. 9A to 9C, a coupon ticket including a product having a PLU code “0010” as a target product is scanned as shown in FIG. If the coupon ticket is BUY2 type, the registration of the coupon ticket is invalid because "1" is set as the sales quantity of the product targeted for the coupon ticket in the coupon registration buffer. Next is no discount. If another coupon ticket that includes the product with PLU code “0001” as the target product is scanned, and the coupon ticket is also a BUY2 type coupon ticket that is valid when two or more target products are purchased, Since "2" is set as the sales quantity of the target product in the coupon registration buffer, the coupon registration becomes valid and the discount amount "$" is displayed as shown in FIG. 9 (5).
0.1 ”is displayed and printed. When the closing key for one registration is further operated, the discount amount is subtracted from the cumulative sales amount, and the total sales amount "$ 4.90" is displayed as shown in FIG. 6 (6) and printed on the receipt.

As described above, when the sales registration of individual products is performed, the contents of the product control flag a ₃ preset in the PLU file are determined according to the PLU codes of those products,
It is determined whether those products are the target products of the coupon ticket. If the product is a target product, the coupon code and the number of sales of products having the coupon code are sequentially stored in the coupon registration buffer.
And when a coupon is used at the end of one registration,
The bar code of the coupon ticket is read, the type of the coupon ticket is discriminated, and it is further judged whether or not the contents of sales registration satisfy the discounting condition. For example, if the used coupon ticket is of a type in which a fixed amount of discount is applied when two or more target products are purchased at the same time, the coupon registration buffer has two or more sales corresponding to the coupon code. If it is two or more, the coupon registration is validated and a certain amount of discount is given.

Therefore, even when discounting with a coupon ticket, the checker does not need to check whether the registered contents satisfy the discount condition of the coupon ticket used (whether the target product has been purchased over a certain number), and the checker Burden is reduced. Furthermore, since it is not necessary to check the registration contents that the checker used to perform, it is possible to set various discount conditions and issue various types of discount tickets, and execute those discounts with a higher efficiency of registration processing than before. it can.

[Effect of device]

According to the present invention, when the customer presents the coupon ticket, the checker does not need to check whether the contents of one registration satisfy the coupon condition corresponding to the presented coupon ticket, and the checker's burden is reduced. In addition, the checker does not need to input the coupon unit price corresponding to the coupon ticket, and the efficiency of the sales registration process can be improved.
