DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

Referring to FIG. 1, reference numeral 1 denotes a customer information display device as a whole, and a number of convenience stores 2A, 2
B ... one or more register terminal devices (3A
1), (3B1, 3B2)...

Register terminal devices (3A1), (3B1,
3B2) are each configured by a computer register having a personal computer 11, as shown in FIG. 2, and each of the convenience stores 2A, 2B,.
When, for example, the clerk 4 inputs the input information to the personal computer 11 via the bus 13 by operating the operation input unit 12, the personal computer 11
Drives the register unit 14 via the bus 13 to perform money deposit and withdrawal processing, and stores the processing data in the memory unit 16.

In the case of this embodiment, when a clerk inputs input data on a sales item name, a unit price, a quantity, and an amount received from the operation input unit 12, the personal computer 11 registers the input data and change data in a register. A receipt is displayed on the display of the unit 14 and printed by the printer of the register unit 14 to emit a receipt to be handed to the customer.

The register terminal devices (3A1) and (3A1)
B1, 3B2) are, as the memory unit 16, a product database 16X for storing sales data for each product, and customers for storing customer data on customers registered as members in the convenience stores 2A, 2B,. When the store clerk 4 operates the operation input unit 12 to read out the member identification number from the member card distributed to the member customer, the personal computer 11 transmits the member identification number of the member customer. The customer information corresponding to the number is read from the customer database 16Y, the customer information is updated based on the result of the product purchase this time, and the process of storing the customer information in the customer database 16Y is executed.

Is stored together with the response information as raw information.

[0015] Of these, as information representing the attributes of the customer,
For example, “customer name”, “address”, “telephone number”, “past history”, “rank by customer”, “last visit date”, “purchase amount of this year”, “monthly sales graph”, “ Breakdown "and" introducer "are used.

As described above, the customer information stored in the merchandise database 16X and the customer database 16Y of the memory unit 16 is transmitted to the data transmitting / receiving unit 1 via the bus 13 at a regular time (eg, 7:00 am) every day.
7, converted into transmission data in a data transmission / reception unit 17, and connected to a line coupler 19 connected to a transmission terminal 18.
To the data transmission line 20 via the

The data transmission line 20 is connected via a line coupler 24 to a server 23 of a customer information storage device 22 installed in a head office 21 of a convenience store, and the transmission data is transmitted by the server 23 to a head office product database. 2
5X and the headquarters customer database 25Y.

Thus, in the headquarters product database 25X and the headquarters customer database 25Y of the headquarters 21, customer information about the member customers of the convenience stores 2A, 2B,.

The customer information stored in the headquarters product database 25X and the headquarters customer database 25Y is stored in the register terminal devices (3A1), (3B1, 3B2) of the convenience stores 2A, 2B,. The customer data is updated so that the daily customer's shopping tendency or change in each convenience store 2A, 2B... Is reflected in the headquarters product database 25X and the headquarters customer database 25Y. The administrator of the headquarters operates the operation input unit 26 to
The customer information in the headquarters customer database 25 is read out to the monitor unit 27 by inputting a read command as necessary, and the convenience stores 2A and 2B
... The customer's daily shopping situation is grasped to analyze the customer's consumption behavior and rank as a whole organization, and the result information is converted into the customer data of the headquarters customer database 25Y by the server 23. It can be added as response information.

The customer data stored in the headquarters product database 25X and the headquarters customer database 25Y is updated via the data transmission line 20 to the convenience stores 2A, 2B,. Distributed. At this time, each register terminal device (3A
The personal computers 11 of (1), (3B1, 3B2)... Transmit the distributed customer data to the product database 16 via the transmission terminal 18, the data transmission / reception unit 17, and the bus 13.
X and the customer database 16Y, and using the stored customer data, when the member customer comes to the store and comes in front of the register terminal devices (3A1, 3B1, 3B2). The customer information is presented to the responding clerk 4 using the monitor unit 15, so that the clerk 4 can provide an appropriate service to the member customer based on the customer information.

In the above configuration, at 7:00 am every day, the server 23 of the customer information storage device 22
Store terminal devices (3A1) of stores 2A, 2B...
(3B1, 3B2) The customer information (consisting of raw information and correspondence information) stored in the product database 16X and the customer database 16Y of the headquarters is transmitted via the data transmission line 20 to the headquarters product database 25X and the headquarters customer database 25Y. In addition, the raw information and the corresponding information which have been accumulated so far are re-created using the raw information, and the headquarters product database 25X is used as new customer information.
Then, the customer information is stored in the headquarters customer database 25Y, thereby updating the customer information in the customer information storage device 22.

After that, the server 23 reads the updated customer information from the headquarters customer database 25 and, via the data transmission line 20, the convenience store 2A,
2B... Register terminal devices (3A1), (3B1, 3
B2) Distribute to.

At this time, the register terminal device (3A1)
(3B1, 3B2) Personal computer 11 of ...
Stores the distributed customer information in the product database 16X and the customer database 16Y of the memory unit 16,
Thus, the register terminal devices (3A1), (3B1, 3B2),... Of the convenience stores 2A, 2B,... And the customer information storage device 22 hold raw information and response information as the latest customer information. .

In this state, when a customer who comes to each of the convenience stores 2A, 2B,... Comes in front of the cash register terminal (3A1), (3B1, 3B2). Causes the personal computer 11 to read the member identification number by inserting the member card into the operation input unit 12.

At this time, the personal computer 11 reads out the response information from the customer information of the member customer stored in the customer database 16Y from the customer database 16Y and displays it on the display screen 15A of the monitor unit 15.

In the case of this embodiment, as shown in FIG. 3, a customer information image in which each customer information item of the following response information is displayed by an icon (ie, pictogram) is displayed on the display screen 15A of the monitor section 15. The IMG is displayed, and the clerk 4 indicates “What kind of service can be provided to the member customer who is currently serving to provide appropriate service”.
Inform

(Equation 1)

The rank is displayed as a percentage, and 3
0.00 [%] or less is regarded as “A's upper rank”, from 30.01 to 50.
00 [%] is regarded as “A middle rank” and 50.01 to 70.00
[%] Is set as “lower rank of A”, 70.01 to 80.00 [%]
As “B rank”, and 80.01 to 90.00 [%]
Medium rank ", 90.01-95.00 [%] is" lower rank B ", and 95.01-100.00 [%] is" higher rank C "
Then, “C middle rank” is assigned to the customer whose sales amount is 0 during the certain period (that is, one year).

The assignment process is executed in the server 23.

The customer rank information 31 is displayed on the display screen 15A shown in FIG.
