2. Description of the Related Art A merchandise sales data processing device processes data that has been registered and accounted for. Product registration function,
By reading and inputting the product information using a scanner and inputting the number and the like using a keyboard as necessary, the product information including the product name and price (unit price) obtained from the product file is stored (product registration) in the sales file. Function. Perform for all products purchased by customers.

The accounting function is a function for executing an accounting process including calculation of a total amount, a change amount, and the like using each registered product information after product registration. Although the closing operation as one transaction end declaration is a condition, registered merchandise information relating to the one transaction is collectively performed.

[0004] In this accounting process, a process of giving service points to be provided to customers as profit returns from stores is performed. That is, when the total amount (purchase amount ... purchase amount ... transaction amount) is calculated by the closing operation after product registration, for example, the criterion obtained according to the total amount stored in the point reference table is multiplied by the total amount. This time point calculated by the above is given. The points this time are accumulated and accumulated in the accumulated points up to that time. For example, it is stored in a point card so that the customer can know the accumulated points up to that point. Thus, the customer can receive the service (prize, discount, etc.) according to the accumulated points.

[0005]

By the way, the provision of service points has a strong color of returning profits to customers who purchase a large amount of money. However, in the conventional giving method, the reference stored in the point reference table (for example, 1 point / 100 yen)
Therefore, there is a dissatisfaction that the service to regular customers who purchase a large amount of money is low while the service is uniform and fair. That is, it is inferior in follow-up to customer differentiation for inducing purchase will.

Therefore, there have been proposed methods of inputting a correction constant to be added to the criterion personally prior to the accounting process, determining a rank for each member, and gradually changing the point criterion for each rank. However, in any case, key input and rank setting work for each customer are complicated and time-consuming. Moreover, since it is likely to be arbitrarily or semi-fixed, it is inferior in follow-up to the specific purchase price and the effect of differentiation is low.

[0007] It is an object of the present invention to provide a merchandise sales data processing apparatus and method capable of objectively and accurately differentiating a purposeful service and having high follow-up performance. Further, a computer-readable storage medium storing a product sales data processing program is provided.

The embodiment will be described.

In the RAM 23, a customer point master file 23M capable of storing the total acquired points of the previous term and the total acquired points of the present term for each customer shown in FIG. 3 and an additional magnification corresponding to the total acquired points shown in FIG. A point magnification table 23R is provided. All are HD
Backed up at D28.

In this embodiment, "member number" is intended for a special member having a large purchase price among members. However, it can be implemented for all members.

Further, in this embodiment, the customer point master file 23M is provided with a cumulative point column, a rank column, and the like. In the cumulative point column, the current point received from the terminal 10 is basically stored as it is, but if the current point is recalculated using the additional magnification, the current point is replaced with the current point. Is accumulated. If the customer receives the return service, the accumulated points are deducted.

The additional magnification extraction control means on the host machine 20 side refers to the customer point master file 23M and the point magnification table 23R when the terminal 10 has been given the current point, and responds to the total acquired points of the customer. The means for extracting the additional magnification is formed from the ROM 22 and the CPU 21 in which the additional magnification extraction control program is stored, and is executed in ST47 of FIG.

In this embodiment, ranking is used in combination for convenience of processing and high-speed processing. Referring to FIG. 3 and FIG. 4, the total acquired points of the previous term “12449” of FIG.

At this time, the rank is read (ranked) and stored in the customer point master file 23M (ST35).

Then, the total acquisition points of the current term are transferred to the total acquisition points of the previous term and stored, and thereafter, the total acquisition points of the previous term are cleared (ST35). This is performed for all customers registered in the customer point master file 23M (ST36).

Here, additional magnification extraction control means (21, 21)
2) receives the current point (“100”) from the terminal 10 in the message shown in FIG. 8A (YES in ST40 of FIG. 7).
Then, the customer point master file 23M is searched, and the additional magnification ("3") corresponding to the previous total acquired points ("12459") is extracted by referring to the point magnification table 23R (ST46) (ST47). In this embodiment, extraction is performed by using the rank (“2”) in place of the previous total acquired points (“12449”).

In this embodiment, the accumulation means (CP
U21, ROM22), in principle, accumulate the current point ("100") given by the terminal 10 as it is in the accumulated point column (ST42). However, when the recalculation described later in detail is performed, the recalculated points are accumulated instead of the current point. If the customer receives a service return, it will be deducted.

This time point recalculation means (CPU 21, R
The OM 22) multiplies the current point (“100”) given by the terminal 10 by the additional magnification (“3”) extracted (ST47) and recalculates the current point (ST48).
I do. After recalculation in this case, the current point is “30
0 "(= 100 * 3).

This term total point accumulation means (CPU 2
1, the ROM 22) stores the current point (“30
0 ”) is stored in the customer point master file 23M, and the customer's total acquired points for the current term (for example,“ 1 ”)
("2000"). The points ("300") are re-calculated using the additional magnification ("3") instead of the points ("100"). Differentiation can be further enhanced:
The ability to follow the purchase price (transaction price) can be greatly improved.

Thus, the re-calculated current point transmitting means (CPU 21, ROM 22) transmits (responds) the re-calculated current point ("300") to the terminal 10 (S).
T50).

Furthermore, in this embodiment, the total acquired points (“15001”) for the current term are compared with the total acquired points (“12
459 ″) or more (Y in ST43).
ES) shows the total points acquired this term (for example, "1500
1 ”) is extracted (ST4).
4, ST45). Respect and advance the performance of large purchases to enhance service and customer differentiation. After recalculation in this case, the point this time is “4
00 "(ST48).

In the terminal 10, the information is provided by its own device 10 (S in FIG. 5).
T15) In place of the current point ("100"), the current point ("300") after recalculation received from the host machine 20 (YES in ST17) is given to the customer (ST18).
I do. Therefore, in the case of the conventional example (ST19)
You can receive three times as many service points as "100" points.

According to the first embodiment, however, the host device 20 has the customer point master file 23M, the point magnification table 23R, and the additional magnification extraction control means (2
