Further, the card reader 4 constitutes an input means for inputting the customer code through a medium called a magnetic card.

FIG. 3 is a control block diagram of the POS terminal 1. As shown in the figure, the CPU (central processing unit) 10 constituting the main body of the control unit controls the respective units by the CPU 11 via a bus line 11. A ROM (Read Only Memory) 12 in which program data and the like for storing data and a RAM (Random Access Memory) 13 in which various memory areas for storing data processed by the CPU 11 are formed are connected. ing.

A clock circuit 1 for measuring date and time
4. The signal of the mode switch 15 for switching various business modes such as “registration”, “inspection”, “payment”, “setting”, etc. is input, and the opening drive signal is output to the drawer 16 for storing cash etc. An I / O port 17, a communication interface 18 for controlling data transmission and reception with the store processor 2 through the communication line 3, a keyboard controller 20 to which a key signal corresponding to an input key is input from a keyboard 19. A display controller 22 that drives and controls the display 21 to display characters and the like corresponding to the display data, and a printer controller 24 that drives and controls the printer 23 to print characters and the like corresponding to the print data on receipts and journal sheets, Card reader interface 25 for inputting magnetic card information read by the card reader 4 Each part of the like are connected to the CPU10 through the bus line 11.

As shown in FIG. 4, the keyboard 19 is provided with a plurality of numeric keys 19a for inputting numerical data such as sales amount and sales quantity of products, and department codes for classifying each product. In addition to a product registration key such as a department key 19b, a multiplication key 19c for inputting a multiplier, a subtotal key 19d for outputting a subtotal amount, and a current total key 19e for declaring registration closing by cash transaction, a clear key 19
f, ten thousand ticket key 19g, discount key 19h, extra key 19
i, # key 19j, currency exchange key 19k, recovery key 19l,
Various function keys such as a PLU (price look up) key 19m, a return key 19n and a cancel key 19p are provided.

As shown in FIG. 5, the RAM 13 is a customer for storing one customer information (customer code, customer name, contribution point, discount rate) called from the customer file 5 of the store processor 2. Information memory 13a,
Also, a total price memory 13b for storing the total price of the products purchased by one customer is formed.

Then, the CPU of each POS terminal 1
11 is programmed to execute the control shown in FIG. 6 in a state where the "registration" mode is selected by the mode switch 15.

That is, as ST (step) 1, the card reader interface 25 is controlled, and the card reader 4
It is determined whether the card information of the magnetic card has been read by. If the card information is not read, ST2
As a result, the keyboard controller 20 is controlled to determine whether there is a key input on the keyboard 19. If there is no key input, the process returns to ST1.

When the card information is read in ST1, the card information is analyzed in ST3 and it is determined whether the card information is a customer card issued to a specific customer. In the case of the card information of the customer card, a customer information inquiry message is created based on the customer code included in the card information in ST4, and this message is sent via the communication interface 18 and the communication line 3 to the store processor. Send to 2.

Here, in the store processor 2, when the customer information inquiry message is received, the customer file 5 is searched using the customer code in the message as a key,
The customer information of the matching customer code is called and transmitted to the inquired POS terminal 1 together with a normal response.

Therefore, the POS that made the inquiry about the customer information.
When the CPU 11 of the terminal 1 receives the normal response from the store processor 2 via the communication interface 18 as ST5, it stores the customer information included in the message as ST6 in the customer information memory 13a of the RAM 13, Go to processing.

When the card information other than the customer card is read in ST3, other processing is executed. Further, if an abnormal response is received from the store processor 2 in ST5, or if no response is received within a predetermined time, whether the information of the customer card not managed by the customer file 5 is read. , There is an abnormality in the communication function connecting the POS terminal 1 and the store processor 2, and therefore an error occurs.

On the other hand, if there is a key input in ST2, the type of the input key is determined. And ST7
If the input key is the discount key 19h, it is determined in ST8 whether the customer information is stored in the customer information memory 13a. If it is stored, the total amount memory 13b is calculated at ST9 with the discount rate in the customer information.
The discount processing of the total amount stored in is executed (discount processing means). After that, the process proceeds to the next process. If there is no customer information in ST8, other processing is executed.

If the input key is the current total key 19e in ST10, it is determined in ST11 whether the customer information is stored in the customer information memory 13a. Only in the case where it is stored, in ST12, the customer code in the customer information is added and the total amount data in the total amount memory 13b is transmitted to the store processor 2.

After that, a predetermined current tightening process is executed,
Go to the next process. Incidentally, the current closing process is the RAM 13
It is a process of adding the total amount of money to the transaction-specific totalizer formed in, and printing and issuing a receipt.

On the other hand, the store processor 2 has RA
A rewritable memory such as M is provided, and the contribution rate points p accumulated for each customer are divided into stages in this memory as shown in FIG. Is provided.

Therefore, the store processor 2 is the PO
When the total amount data is received from the S terminal 1 side through the communication line 3, first, as shown in FIG. 8, a contribution point to the total amount, for example, 1 point for every 100 yen is calculated (point calculation means).

Then, the customer file 5 is searched for the customer code in the received data, and the contribution point calculated this time is added to the contents of the contribution point area corresponding to the matching customer code (Poiton updating means).

Next, the discount rate table 30 is searched with the added contribution points to read the corresponding discount rate (discount data determining means). Then, the contents of the discount rate area corresponding to the customer code are compared, and if there is a change, the content of the corresponding discount rate area is changed to the discount rate read from the discount rate table 30 (discount data storage). means).

In a store in which the POS system of this embodiment having such a configuration is introduced, a customer card to which a customer code assigned to the customer is magnetically recorded is given to a particular customer who is given the discount service. At the same time as issuing, a customer file 5 in which the customer code and customer name of each customer are preset is created.

When a specific customer comes to pay for the purchased product, the operator of the POS terminal 1 first deposits the customer card possessed by the customer and reads the card information with the card reader 4. Let Then, the customer code included in the card information is inquired to the store processor 2, and the customer information (customer code, customer name, contribution point, discount rate) is returned from the store processor 2, and the customer information memory is returned. 13a.

Next, the operator operates the number registration key 19a, the department key 19b, the multiplication key 19c, etc. of the keyboard 19 to perform product registration for the product purchased by the customer. When the registration of all the products is completed, the total price is stored in the total price memory 13b.

In this state, the discount key 19h is keyed in. Then, the total amount in the total amount memory 13b is discounted at the discount rate in the customer information memory 13a. For example, if the total amount is 1000 yen and the discount rate is 3%, a discount amount of 30 yen is calculated, and the total amount is discounted to 970 yen.

Thereafter, when the customer makes a payment in cash commensurate with the total amount after discounting, the operator pays the current key 19
Key in e to close registration. Then, the total amount data after the discount calculation is transmitted to the store processor 2 together with the customer code in the customer information memory 13a.

In the store processor 2 which has received the total amount data, the contribution point is calculated from the total amount in the data. For example, the contribution point is 10
If one point is given for 0 yen and the total amount is 970 yen, 9 is calculated as the contribution point of this time.

Then, the present contribution point is added to the content of the contribution point area corresponding to the corresponding customer code in the customer file 5, that is, the cumulative value of the contribution points calculated for each shopping up to now. Further, the discount rate is determined from the contribution points after the addition based on the setting contents of the discount rate table 30. For example, when the setting content of the discount rate table 30 is as shown in FIG. 7, the discount rate is determined to be 3% when the contribution point is 100 points or less, and 5 when the contribution point is more than 100 points and 500 points or less. %, And if it is more than 500 points and 1000 points or less, it is determined as 10%.

Then, the contents of the discount rate area corresponding to the corresponding customer code in the customer file 5 are changed to the determined discount rate. For example, if a customer who has accumulated 95 contribution points up to the previous time added 9 points in this shopping, the discount rate was 3% up to this time, but 5% from the next shopping.

As described above, in this embodiment, the contribution points are accumulated for each customer, and the discount rate is set according to the accumulated contribution point value. Then, the total price of the purchased products is discounted at the discount rate set every time the customer makes a purchase. In this case, it is not necessary to key in the discount rate with the numerical key 19a, but it is only necessary to key in the discount key 19h after registration of the purchased product. Therefore, it is possible to perform discount calculation at a discount rate different for each customer without the need for a complicated operation of inputting the discount rate as a numerical value, and it is possible to improve operability.

The present invention is not limited to the above embodiment. For example, in the above-mentioned embodiment, the discount rate is set for each customer based on the contribution point so far, but the discount amount may be set.

Further, as a method of calculating the contribution point, for example, points are given when a particular product is purchased, or a contribution point and a discount rate are recorded in a customer card as a customer information management method. Needless to say, various modifications can be made without departing from the scope of the invention.

[0042]

As described in detail above, according to the present invention, the discounting operation of the proportion according to the customer's contribution points up to now can be performed only by entering the discount key without entering the discount data. It is possible to provide a product sales data processing device that can be processed and can be improved in operability.
