Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a general customer who can register a product using a normal unit price and a member customer can register a product using a member unit price lower than the normal unit price.
The present invention relates to a merchandise sales data processing method and a merchandise sales data processing system for giving points according to the purchase amount to general customers and member customers.

[0002]

2. Description of the Related Art A merchandise sales data processing system has a merchandise registration function for a customer purchased merchandise, an accounting processing function including calculation of a total price, and the like. In addition, as a measure of customer service, there is a case where a differentiated discount function is provided for regular customers (member customers) to provide services such as discounts (discounts) that are differentiated from ordinary customers.

Further, in many cases, a common point providing function for providing service points proportional to the level of the sales amount (purchase amount) is provided. The point is an index for obtaining a prize or receiving a discount, which is given in accordance with a purchase amount (for example, referred to as a subtotal amount or a total amount) in one transaction in which a product is registered.

[0004] That is, when an operator inputs a product code of a customer purchased product using a scanner or a keyboard, a control unit (computer) searches a product file (or a product master file of a higher-level device) and stores the product code in the product code. The corresponding product data [product name (for example,
"Potato chips"), unit price, etc.], and register the product in the sales file.

[0005] In the case where a differentiated discount function is provided, the unit price used for registering this product is a regular unit price (for example, "300
Yen)), the lower the unit price of the member (for example, “100 yen”)
Is used. It provides differentiated services (discounts) to its members.

[0006] The receipt printing unit price creation means for the member customer converts the member unit price ("100 yen") of the member's purchased product ("potato chips") into the normal unit price ("300 yen").
Yen)), the receipt printing unit price for member customers (“30
Then, the member preferential discount discount calculating means converts the member unit price (“100 yen”) to the normal unit price (“300 yen”).
The member discount “¥ 200” is calculated by subtracting “yen”).

Thus, as shown in FIG. 10 (B), the general customer receipt printing unit price to be printed on the receipt 75B for ordinary customers is the normal unit price (300 yen), whereas FIG. The printing unit price of the receipt for the member to be printed on the receipt 75AP of the member customer shown is replaced with the created unit price (300 yen), and the calculated discount for the member preferential treatment (-200 yen) is printed. It is printed on the receipt 75AP in association with the unit price (300 yen).

The same applies to the product ("wine") shown in FIGS. 10 (A) and 10 (B).

Further, the means for calculating the purchase amount for the member customer calculates the purchase amount of the member customer by the member unit price ("100" of potato chips).
And the price of wine "1000 yen") (1100 yen = 100 + 1000) .The general customer purchase price calculation means calculates the general customer purchase price by the normal unit price (potato chips "300 yen" and "2000" of wine
Yen ") (2300 yen = 300 + 2000). The subtotal amount to be printed on the receipt is the calculated general customer purchase amount (2300 yen) for general customers (receipt 75B) and member customers (Receipt 75
AP), the calculated purchase price for the member customer (110
0 yen).

[0010] When the merchandise registration for all of the merchandise purchased by the customer is completed, a closing operation as one transaction end declaration is performed, and the purchase amount (total amount) in one transaction is calculated. That is, the consumption tax (“55 yen” for the member customer, “115 yen” for the general customer) and the total (“1155 for the member customer”)
Yen "," 2415 Yen "for general customers) is calculated, and in this case, cash payment is made.

[0011] Further, when a point providing function is provided,
The control unit (CPU) converts the purchase amount [in this case, subtotal amount ... for general customers (2300 yen), for member customers (1100 yen)] based on the awarded point calculation program stored in the memory (for example, ROM). The corresponding assigned points Pi [for general customers (23 points), for member customers (11 points)] are calculated and temporarily stored in the memory (RAM).

Thereafter, the current point P is calculated by adding the given point Pi to the previous service point (P), and a sheet on which the current point P is printed out is issued. In the case where a point card system is provided, point card processing such as cumulative writing of the current point P is performed in place of the previous service point (P) stored in the point card.

[0013] Thus, the customer receives the total number of service points (Pi) assigned to each purchase, that is, the current point P.
(For example, “398”), a discount or a premium can be obtained. On the other hand, at stores, it is possible to obtain customer attraction and promote sales.

Here, in the case of a member customer, the means for calculating the total purchase price is determined by the sum of the member discount discount [−1200 yen = −20].
0 + (− 1000)] to calculate the total amount of the bargain (1200 yen with the inverted sign) and FIG.
As shown in (A), the total purchase price (1200 yen) calculated in association with the current point (11 points) printed on the receipt 75AP is printed.

[0015]

By the way, in the actual operation, if both services are provided by the differentiated discount function and the common point giving function, the members and general customers who can greatly contribute to the sales of the store will be connected. It is understood that, since the unit price at the time of merchandise registration differs between purchases of the same merchandise, a difference occurs in the purchase price in terms of providing a differentiated discount service.

However, if we focus on the concept that points as a common point acquisition function (service) for attracting customers are given according to the purchase price, the purchase price will be lower when the unit price of the member is used. The customer is disadvantaged in terms of point giving as compared to the general customer. It has been increasingly pointed out that member customers have not really enjoyed the differentiated discount service.

An object of the present invention is to provide a commodity sales data processing method and a commodity sales data which can execute both a differentiated discount function and a common service point giving function while preventing a member customer from being disadvantagedly differentiated. It is to provide a processing system.

[0018]

According to a first aspect of the present invention, a general customer is registered by using a normal unit price by computer processing and a product is registered by using a member unit price lower than the normal unit price with a member customer. In addition, in the merchandise sales data processing method for giving points according to the purchase amount, the merchandise registration and the point awarding for the general customer are performed using the normal unit price, and the merchandise registration for the member customer sets the member unit price. This method is a commodity sales data processing method that uses the normal unit price to give the points despite the use of the points.

In this invention, a general customer registers a product using a normal unit price, but a member customer registers a product using a member unit price. The unit price (for example, 100 yen) of one product (for example, potato chips) is lower than the normal unit price (for example, 300 yen), so that a substantial discount service is provided to the member customers. It is a differentiation that is superior to member customers.

However, focusing on the concept that points as a service for attracting customers are given in accordance with the purchase price, if the unit price of the member (100 yen) is used, the purchase price (100 yen) is the purchase price of ordinary customers. (300 yen). In other words, the member customer is disadvantageously differentiated with respect to the point giving as compared with the general customer. Therefore, a low member unit price (100
In spite of the fact that the purchase is made using the same unit price (300 yen) as in the case of the general customer, the point is given to the member customer despite the fact that the purchase is performed using the same unit price (300 yen).

[0021] Therefore, the same service as that of a general customer is provided to the member customer without being disadvantageously differentiated with respect to the point giving, while ensuring the superior differentiation of discounting the product registration using the unit price of the member. Can be. That is,
It is possible to execute both the differentiated discount function and the common point grant function while preventing the member customer from being disadvantagedly differentiated.

According to the second aspect of the present invention, a general customer can register a product using a normal unit price and a member customer can register a product using a member unit price lower than the normal unit price. In a merchandise sales data processing system formed so that points corresponding to the purchase amount can be given to each of the member customers, a general customer product registration control means for performing the product registration for the general customer using the normal unit price And a general customer point giving control means for giving the current point according to the general customer purchase amount using the normal unit price, and a member customer product for registering the product using the member unit price for the member customer. A registration control means and a member customer point grant control means for granting points this time according to the purchase price for the member customer using the normal unit price. Product sales that can provide the same points this time without discrimination with ordinary customers using normal unit prices while guaranteeing the provision of discount services using differentiated member unit prices that are lower than the normal unit price It is a data processing system.

In this invention, for the general customer, the general customer product registration control means registers the product using the normal unit price (300 yen), and the general customer point assignment control means performs the normal unit price (300 yen). ) Is given this time point (3 points) according to the purchase amount for general customers.

However, for the member customer, the product registration control means for the member customer registers the product using the unit price of the member (100 yen), but the point grant control means for the member customer sets the normal unit price (300 yen). This time point (3 points) is given according to the purchase amount (300 yen) for the member customer used.

In other words, with respect to the purchase amount of the member customer, the provision of the discount service using the differentiated member unit price lower than the normal unit price is assured, and the point awarding this time is the same as that of the general customer using the normal unit price without discrimination. This time points are given. Therefore, it is possible to execute both the differentiated discount function and the shared point giving function while avoiding the disadvantageous differentiation of the member customer, and the handling is simple.

The invention according to claim 3 is a member preferential discount discount calculating means for calculating the member preferential discount by subtracting the normal unit price from the member unit price, and a member preferential discount discount calculated for each registered product. A total purchase price calculating means for calculating a total purchase price as a sum is provided, and the total purchase price calculated in association with the present point printed on the receipt and the same amount as the purchase price for the member customer are provided. It is a merchandise sales data processing system that prints a target point amount on a receipt.

In this invention, the member discount discount calculating means calculates the member discount (−20) obtained by subtracting the regular unit price (300 yen) from the member unit price (eg, 100 yen) for the product A.
0 yen). As for the product B, the member discount (−1000 yen) is calculated by subtracting the normal unit price (2000 yen) from the member unit price (eg, 1000 yen).

Further, the total purchase price calculating means calculates the sum (1200 yen = 2 yen) of the calculated member discount discount (200 yen, 1000 yen with inverted sign) for each of the registered products A and B.
00 + 1000) as the total price (1200 yen)
Is calculated.

Thus, the total purchase price (1200 yen) calculated in relation to the current point (for example, 23 points) printed on the receipt and the member customer points of the same amount as the member purchase amount (2300 yen) Print the target amount (2300 yen) on the receipt

Therefore, in addition to providing the same operation and effect as in the case of the second aspect of the present invention, a differentiated discount service of the total purchase price (1200 yen) is provided to the member customer, Point target amount (2300
(Yen) is given as the same product price (2300 yen) as that of a general customer. In other words, it is possible to re-appeal to the member that the dual service is provided, and it is also safe for the member customer because it is possible to confirm that the point is given after the differentiated discount service has been performed.

Further, the invention according to claim 4 includes a plurality of terminals connected to the data communication network and a higher-level device having a collective management function for each terminal. When an inquiry about a designated customer is received, if the designated customer is a general customer by referring to the product master file, the terminal can respond to the terminal with the normal unit price for the designated product, and the designated customer is a member customer. For the inquiry that is, the member unit price and the normal unit price for the designated product are formed so as to be able to respond to the terminal.
When the designated customer is a general customer, the data processing including the product registration and the point assignment is performed using the normal unit price returned from the higher-level device, and when the designated customer is a member customer, the normal unit price is returned from the higher-level device. This is a merchandise sales data processing system formed to be executable using both the member unit price and the normal unit price.

In this invention, when the host machine receives a product inquiry including a product designation and a customer designation from each terminal, the host device refers to the product master file and, for an inquiry in which the designated customer is a general customer, the inquiry about the designated product. Is returned to the terminal, but for an inquiry in which the designated customer is a member, both the membership unit price and the normal unit price for the designated product are returned to the terminal.

Each terminal executes data processing including merchandise registration and point assignment using a normal unit price returned from a higher-level device when the designated customer is a general customer, but executes the data processing including a member customer when the designated customer is a member customer. Is executed using both the member unit price and the normal unit price returned from the host machine.

Therefore, in addition to providing the same operation and effect as in each of the inventions of claims 2 and 3, in addition, each terminal has the same member unit price and the same unit price for the same product from a common host machine. Therefore, it is possible to reduce the memory capacity of each terminal while ensuring accurate and accurate product sales data processing without variation.

Has a batch management function.

In the HDD 84, a product master file 84MF (shown in parentheses in FIG. 3) shown in FIG.
A sales master file 84MU and the like are formed.
It is developed and used in M33.

The host machine (80) is connected to each terminal (1).
0), a product inquiry (ST12, ST17) including a customer designation (ST11 in FIG. 4 showing the terminal) and a customer designation (ST11) is received.
Inquiry that the designated customer is a general customer with reference to the product master file 84MF shown in FIG. 3 (NO in ST11, ST17)
For the designated product (for example, “potato chips”), the normal unit price Pn (for example, “300
("Yen") to the terminal (10) (Y in ST18).
ES) is possible, and for the inquiry (YES in ST11, ST12) that the designated customer is a member customer, the member unit price Pk ("100 yen") and the normal unit price Pn ("300 yen") of the designated product are included in the inquiry. Terminal (10)
(YES in ST13).

In FIG. 1, an electronic cash register 10 forming a terminal is formed by connecting an external input / output device to a personal computer 20 including a standard input device (keyboard 43).

The personal computer 20 has a CPU 3
1, a HDD (hard disk device) 41, an FDD (floppy disk device)
42, keyboard 43, input / output port (I / O) 4
6 and 47 and a communication interface (I / F) 44 for performing data communication with the host machine (store controller 80) via the data communication network 45.

A scanner (SCN) 71 and a card reader / writer (R / W) 73 for a point card are connected to the input / output port 46.
The input / output port 47 includes a printer (PNT) 75 and other output devices (OTH: automatic opening type drawer, etc.) 76
Is connected.

Further, an operator display (FIU) 61 and a customer display (BIU) 65 constituting the display means 60 are connected to the controller 30 via a display controller 50. In addition, a touch panel 62 corresponding to an operator display (FIU) 61 and a touch panel 66 corresponding to a customer display (BIU) 65 are connected via each controller (CONT).

In the HDD (memory) 41, in addition to the product file 41F and the sales file 41UF shown in FIGS. 1 and 3, various files and various controls related to the product sales data processing shown in FIGS. The program is stored. Each file is developed in the RAM 33 and used.

When the designated customer is a general customer (NO in ST11 and ST17 in FIG. 4), each terminal (10) responds to the data processing including merchandise registration and point assignment from the host machine (80). If the designated customer is a member customer (ST11 in FIG. 4, ST12 in FIG. 4) using the normal unit price Pn given in ST18 (YES in ST18), the member responded from the host machine (80) (YES in ST13). It is formed executable using both the unit price Pk and the normal unit price Pn (ST14).

The merchandise data returned from the merchandise master file 84MF of the higher-level machine (80) is stored in the merchandise file 41F shown in FIG. 3 of each terminal (10), and merchandise data is directly transferred from the merchandise file 41F in the own machine. Can be obtained. In other words, the host machine (80) can be indirectly inquired and handled as a response.

When the operator inputs the product code (for example, “4912345678901” in FIG. 3) of the customer purchased product using the scanner 71 or the keyboard 43 (YES in ST10 in FIG. 4), the customer is identified as a member customer (for example, Member number) already entered (YES in ST11)
If it is, the member registration control means (CPU3
3, the ROM 32) searches for the product file 41F (copy of the product master file 84MF on the higher-level device side) and
The corresponding product code (“49123467890
1 ") [As the product inquiry code to the higher-level device, the member code (ST12)" 14912334789090 "
1 "]. Product data [product name (" potato chips "), unit price (Pk" 100 yen "and Pn
“300 yen”) and the like, and while temporarily storing (ST14), the product is registered in the sales file 41UF using the member unit price Pk (“100 yen”) (ST21).

If the customer is not a member (for example, a member number) is input (NO in ST11), that is, if the customer is a general customer, the commodity registration control means for general customers (CPU 31, RO
M32) retrieves the product file 41F (a copy of the product master file 84MF on the host machine side), and finds the product code (“4912345678901”) shown in FIG. 3 [the product inquiry code is “for general customers (ST17)” 0
Product data [product name (“potato chips”) ”, unit price Pn.
("300 yen") etc.] and temporarily store them (ST19).
Then, the product is registered in the sales file 41UF using the normal unit price Pn ("300 yen") (ST21).

That is, regarding the differentiated discount function, the unit price used for registering the product (ST21) is as follows:
A member unit price Pk (for example, "100 yen") lower than the normal unit price Pn (for example, "300 yen") of FIG. It provides differentiated services (discounts) to its members.

Then, the member unit price processing (ST15 in FIG. 4)
Proceed to. First, receipt printing unit price creation means (C
The PU 31 and the ROM 32 store the member unit price Pk (“100”) for the product purchased by the member customer (“potato chips”).
In step S151, the unit generates a receipt printing unit price Pr ("300 yen") for the member customer in which "¥" is replaced with the normal unit price Pn ("300 yen") (ST151 in FIG. 6).

Next, the member discount discount calculating means (CPU
31, ROM32) is the member unit price Pk ("100 yen")
Is subtracted from the normal unit price Pn ("300 yen") to calculate the member discount ($ 200) ($ P = Pk-Pn) (ST152 in FIG. 6).

Thus, as shown in FIG. 9B, the general customer receipt print unit price Pr to be printed on the general customer receipt 75B is the normal unit price Pn (300 yen), whereas FIG. ) Is replaced with the member unit receipt printing unit price Pr to be printed on the member customer receipt 75A as the created unit unit price Pn (300 yen), and the calculated member preferential discount ΔP (-200 yen). It can be printed on the receipt 75A in association with the member customer receipt print unit price Pr (300 yen) (ST16).

In the case of ordinary customers, the normal unit price Pn (“300
The circle ") is printed as it is on the receipt 75B of FIG. 9B (ST20).

The above-described member unit price processing and the like are described in FIG.
The same applies to the products ("wine") shown in (A) and (B).

Returning to FIG. 4, after registering the product, the process proceeds to a subtotal amount (purchase amount) calculation process (ST22, FIG. 7). That is, the purchase amount calculation means for the member customer (CPU 31, ROM 3
2) is the sum (1100 yen = 100 + 100) of the purchase amount (subtotal amount Ask) of the member customer and the unit price of member Pk (“100 yen” for potato chips and “1000 yen” for wine)
0) (Ask = ΣPk) (ST2 in FIG. 4).
2. YES in ST221 in FIG. 7, ST222).

One general customer purchase price calculation means (CPU
31, ROM 32) contains the purchase amount (subtotal amount A) of ordinary customers.
sn) to the regular unit price Pn ("300 yen" of potato chips)
And "2000 yen" of wine (2300 yen = 3)
00 + 2000) (Asn = ΣPn) (ST22 in FIG. 4, NO in ST221 in FIG. 7, ST22)
3).

The subtotal amounts Ask and Asn to be printed on the receipts 75A and 75B are calculated using the calculated general customer purchase price (2300 yen) for general customers and the member unit price for member customers. The purchase price for member customers (1100 yen).

Subsequently, when the merchandise registration for all of the merchandise purchased by the customer has been completed, if a closing operation (YES in ST23 of FIG. 4) is performed as a declaration of completion of one transaction, the purchase amount (total amount At) in one transaction is reduced. The calculation is performed (ST24 in FIG. 6). That is, the consumption tax shown in FIGS. 9A and 9B (“55 yen” for member customers, “115 yen” for general customers) and the total (“1155 yen” for member customers, “2415
Yen ") is calculated, in this case cash payment.

After the calculation of the total amount At, the common point giving function is executed (ST26, ST28 in FIG. 5).

General customer point assignment control means (CPU 3
1, the ROM 32) performs the normal point giving process (S in FIG. 5).
NO in T25, ST28). That is, the memory (H
DD41), the purchase amount [in this case, the subtotal amount A
sn (2300 yen)], the current point Pi [for general customers (23 points)] is calculated and stored in the memory (RAM3
Store temporarily in 3).

Member point giving control means (CPU 3
1, the ROM 32), based on the member customer present point assignment calculation program stored in the memory (HDD 41), a member point assignment process (YES in ST25, ST2 in FIG. 5).
6, FIG. 8). This process is performed in three stages.

That is, in FIG. 8, the total purchase amount calculation means (CPU 31, ROM 32) calculates the sum of the member discount discount △ P [−1200 yen = −200 + (− 100)
0)] as the total purchase amount Atk (1 with the sign inverted).
200 yen) (Atk = | Σ △ P |) (ST2)
61).

The point target amount calculating means (CPU 3
1, ROM32) is the point P
Calculate the point target amount Atpt, which is the target amount (purchase amount for member customers) for calculating i (Atpt = ｔPn).
(ST262). This point target amount Atpt is
This is the sum of normal unit prices Pn for general customers ($ Pn). As a result, it is equal to the subtotal amount Asn (2300 yen) for general customers.

Further, the current point calculating means for the member customer (corresponds to a substantial point giving control means for the member customer).
[CPU 31, ROM 32] calculates the current point Pi [for member customers (23 points)] according to the calculated point target amount Atpt ("2300 yen") (ST26).
3) Then, it is temporarily stored in the memory (RAM 33).

Thus, the current point Pi for the member customer
(23 points) to the member receipt 75 of FIG. 9 (A).
A is printed (ST27 in FIG. 5). The current point Pi for general customers [for general customers (23 points)] is printed on the receipt 75B shown in FIG. 9B (ST29 in FIG. 5).

After that, the presently assigned points Pi
(23 points) to previous service points (P)
And the current point P is calculated, and a sheet on which the current point P is printed out is issued. If a point card system is provided, point card processing (ST30) such as cumulative storage (writing) of the current point P is performed instead of the previous service point (P) stored in the point card.

Thus, the customer can obtain a discount or a prize according to the total number of current points (Pi) awarded for each shopping, that is, the current point P (for example, "398"). On the other hand, at stores, it is possible to obtain customer attraction and promote sales.

According to this embodiment, the general customer product registration control means (31, 3) is provided to the general customer.
2) performs product registration (ST19, ST21 in FIG. 4) using the normal unit price (300 yen), and the general customer point giving control means (31, 32) performs the normal unit price Pn (300 yen +
2,000 yen) for general customers (2300 yen)
Are given (23 points in FIG. 5).

For the member customer, the merchandise item registration control means (31, 32) performs the merchandise registration (ST14, ST15, ST21) using the member unit price (100 yen). The point giving control means (31, 32) uses the normal unit price (300 yen) to purchase the member customer (300 yen).
The current point (23 points) according to (yen + 2000 yen) is given (ST26 in FIG. 5, ST263 in FIG. 8).

In other words, regarding the purchase amount of the member customer, the provision of the discount service using the differentiated member unit price Pk (“100 yen”), which is lower than the normal unit price Pn (“300 yen”), is secured while securing the point Pi of the current point Pi. Regarding the award, the same point Pi (“23 points”) that is the same as the ordinary point using the normal unit price Pn (“300 yen” + “2000 yen”) is provided without discrimination. Therefore, it is possible to execute both the differentiated discount function and the shared point giving function while avoiding the disadvantageous differentiation of the member customer, and the handling is simple.

The member discount discount calculating means (31, 3)
2) from the unit price Pk (“100 yen”) for the product (“potato chips”) to the normal unit price Pn (“300
Yen discount) minus member discount $ P (“-200 Yen”)
Is calculated (ST152 in FIG. 6). Product ("Wine")
For member discount Pk (“1000 yen”) minus regular unit price Pn (“2000 yen”)
(“−1000 yen”) is calculated (ST152 in FIG. 6). The discount for all members is $ 1200.

Further, the means for calculating the total amount of the purchase (31, 3
2) is a member discount discount P for each registered product (“potato chips”, “wine”) calculated in ST152 of FIG.
Yen ") (" 1200 yen "=" 200 "+" 100 ")
0 ”), and the total purchase price Atk (1200 yen) is calculated (ST261 in FIG. 8).

Thus, the receipt 75 shown in FIG.
This time point Pi printed on A ("23 points")
