Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register (hereinafter referred to as EC
Called R. ) Concerning.

[0002]

2. Description of the Related Art Conventionally, there is a method of selling a product in which a discount is made in accordance with a predetermined rule when a purchased product satisfies a predetermined condition such as a total number or a combination. For example, when a certain product is purchased in a batch of n pieces, a so-called bulk sale is offered, in which m yen is discounted, or when a product a, a product b and a product c are purchased, m is purchased.
There is so-called combination selling that offers yen discounts. Also,
As a sales method similar to this combination sales, for example, a so-called wagon sale in a department store or the like, which is a target of a discount, is selected from a plurality of kinds of products having mutually different unit prices, and a predetermined number, for example, 3 A selling method is used in which when an individual is purchased, a predetermined fixed amount, for example, 290 yen is charged.

FIG. 12 is a flow chart showing the operation at the time of sales registration by the conventional ECR in the case of the above-mentioned wagon sale, and FIG. 13 is a key input operation and display contents at this time (print contents of receipt here). FIG. In FIG. 12, in step a1, department registration, PLU (Price Look Up) registration described later, or JAN (J
apanese Article Number) Register the product by registration. In step a2, it is determined whether or not the product registration is completed. If it is completed, the registration is closed in step a3 and the billing amount is calculated in step a4. When the product registration is not completed in step a2, the process returns to step a1 and the process is continued until all the product registrations are completed.

This sales registration operation is performed by three products represented by a PLU code, for example, 1 represented by PLU0001.
Fig. 13 shows a product A of 00 yen, a product B of 110 yen represented by PLU0002, and a product C of 120 yen represented by PLU0003. As shown, product registration is input in order using the "1", "2", "3" keys and the PLU key. At this time, when the third product (here, product C) is input, the ECR is automatically discounted from the third registered product C (here, 40 yen for the total price of 290 yen). Make a discount). After the product registration is completed, the cash / exchange key is used to perform the closing registration, and the invoiced amount of 290 yen is printed.

Further, in the above-mentioned wagon sale, 3
There is also a selling method such as a so-called multi-level discount in which a condition is further added to the selling condition that the price is 290 yen when the individual is purchased, for example, 450 yen when the 5 is purchased.

[0006]

As described above, in the wagon sale, when the predetermined number of merchandise registrations in the ECR, for example, three, are input, the total amount of money is set to a predetermined fixed amount. The discount is automatically applied from the second registered product.

[0007] Here, in the wagon sale that costs 290 yen when three of the above-mentioned products A, B and C are purchased,
For example, when two products A, one product B, and one product C are purchased, the following cases can be considered as a method of registering products in the ECR.

[0008]

[Table 1]

As shown in Table 1, when the order of product registration in the ECR is A → A → B → C, the third product B registered so that the total amount of the three products is 290 yen. The discount is automatically applied from the unit price of. Then, the unit price of the fourth registered commodity C of 120 yen is added, and the subtotal is calculated to be 410 yen.

If the order of product registration is C → B → A → A, the unit price of the product A registered third is automatically discounted, and the unit price is registered fourth. The unit price of the product A of 100 yen is added to calculate the subtotal of 390 yen.

As described above, in the wagon sale, there is a problem that the total amount of money varies depending on the order of registration of the products in the ECR even if the products have the same combination.

The ECR described above is a multi-step discount having a plurality of combination conditions because the discount calculation is performed when a predetermined number of products are input during product registration, that is, when the combination conditions of the products are satisfied. There is a problem that we cannot deal with the wagon sale.

Therefore, an object of the present invention is to provide an electronic cash register which can cope with a wagon sale in which multi-step discounts can be performed without causing a difference in the total amount depending on the order of product registration. That is.

Here, the processing operation when the eraser, the ballpoint pen, and the ruler are purchased in the number of 2, 3, and 4 respectively under the discount condition for the combination number 01 described above will be described.

At step b1, it is judged whether or not the product information is input to the ECR1. If the product information is input, the product is registered by PLU registration at step b2. At step b3, it is judged whether or not the registered merchandise has a pointer number set, and if it is the merchandise that has been set, that is, if the merchandise is a wagon sale target merchandise, at step b4, the sales quantity file 11 Individual storage area 62a-
The sales quantity of 62c is cumulatively added according to the product registration, and it is determined in step b5 whether or not the product registration is completed. If the product registered in step b3 is not the product for which the pointer number is set, that is, if the product is not the target product of the wagon sale, the process of step b4 is not performed and step b
Go to 5. If the product registration is not completed in step b5, the process returns to step b2 to continue the product registration process, and if the product registration is completed in step b5, that is, the individual storage areas 62a, 62b of the sales quantity file 11, 6
When the sales quantities of 2c are 4, 3 and 2, respectively, tightening registration is performed in step b6. At step b7, the discount calculation according to the discount condition associated with the combination number 01 is performed to calculate the total amount. The calculation method at this time will be described below.

First, of the sales quantities stored in the sales quantity file 11, it is determined whether or not the discount conditions are satisfied in order from the individual storage area 62a. Here, the basic quantity of 5 is established once by 4 rulers and 1 ballpoint pen. Therefore, the discount amount at this time is

[0032]

## EQU00001 ## (120.times.4 + 110.times.1)-(450.times.1) = 140 yen is calculated. Next, it is further determined whether or not the condition is satisfied with respect to the remaining number which is not the target of the condition. As a result, 2 ballpoint pens and 1 eraser will make the basic quantity 3
The individual is established once. Therefore, the discount amount at this time is

[0033]

## EQU00002 ## (110.times.2 + 100.times.1)-(290.times.1) = 30 yen is calculated. Since the condition is satisfied, the total discount amount is calculated as 170 yen and the total amount is calculated. In addition,
As described above, in the sales quantity file 11, the data are arranged in order from the one with the highest unit price, so that the determination of the satisfaction of the condition is made from the one with the highest unit price. Therefore,
The best discount for customers is realized.

At step b8, the calculated total amount and the like are printed on a receipt and displayed. FIG. 8 shows an example of printing the receipt 70 at this time.

As shown in FIG. 8, on the receipt 70, the unit price and the sales quantity, the product name and the subtotal amount are printed for each purchased product. Further, in the receipt 70, in order to show that the discount calculation is performed under the discount condition related to the combination number 01 stored in the combination file 7, the texts of the discount 2 and the discount 1, that is, “nebiki 2” and “nebiki 1”.
Then, the number of times each discount condition is satisfied and the discount amount under each discount condition are printed, and finally the total amount is printed.

At step b9, calculation processing such as consumption tax is performed, and the process returns to step b1.

When the product information is not input in step b1, it is determined in step b10 whether the subtotal key 23 is pressed. When the subtotal key 23 is pressed, the same processing as the discount calculation in step b7 is performed to calculate the subtotal amount, that is, the total amount at this point, the subtotal amount is displayed in step b12, and the process proceeds to step b5. Continue processing. If the subtotal key is not pressed in step b10, the process proceeds to another process.

The above processing has been described for the case of the discount condition of the combination number 01, but in the following, the calculation method of the discount amount for the discount condition of the combination number 02 stored in the individual storage area 47b of the combination file 7 will be described. Will be described. Here, eraser, ballpoint pen, and ruler are 3, 5,
The processing operation when seven pieces are purchased will be described.

First, of the sales quantities stored in the sales quantity file 11, it is sequentially determined from the individual storage area 63a whether or not the discount condition is satisfied. here,
With four rulers, the basic quantity of four is established once. Therefore, the discount amount at this time is

[0040]

## EQU00003 ## (120.times.4) -350 = 130 yen is calculated. Also, the basic quantity of 4 is established twice with 3 rulers, 1 ballpoint pen, and 4 ballpoint pens. Therefore, the discount amount at this time is

[0041]

## EQU00004 ## (120.times.3 + 110.times.5) -350.times.2 = 210 yen is calculated. In addition, 2 erasers and 1 of the basic quantity is 1
It holds twice. Therefore, the discount amount at this time is

[0042]

## EQU00005 ## (100.times.2) -190 = 10 yen is calculated. Since the condition is satisfied with this, the total discount amount is

[0043]

[Equation 6] 130 + 210 + 10 = 340 yen is calculated, and the total amount of money is calculated.

FIG. 9 is a diagram showing a printing example of the receipt 80 at this time. As shown in FIG. 9, the receipt 80 is printed with the unit price and the sales quantity, the product name (here, PLU code), and the subtotal amount for each purchased product. Further, in order to indicate that the discount calculation is performed on the receipt 80 under the discount condition associated with the combination number 02 stored in the combination file 7, the texts of the discount 2 and the discount 1, that is, "Wagon 1-2" and "Wagon 1-". 1 ”, the number of times each discount condition is established, and the discount amount under each discount condition are printed. In addition, the taxable amount such as consumption tax is also printed, and finally the total amount is printed.
