Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data processing apparatus having a function of providing a service according to a purchase result of a customer in a form according to a sales policy of a store.

"Prior art" Recent sales data processing equipment (customer management system)
It has a customer service management function, that is, a function of registering and managing the purchase results of customers and providing service data based on the purchase results, and is popular among stores, especially small-scale stores. As this kind of sales data processing device,
Two types of sales data processing apparatuses are provided, in accordance with the service sales provision system on the store side, a sales data processing apparatus having a collective rebate processing function and a sales data processing apparatus having an immediate rebate processing function. In each of these two types of sales data processing devices, the customer is mainly identified by inputting a card, and individual processing of the customer data is performed.
For this reason, the store issues a membership card for inputting customer identification data to customers who have become members. With the former device of the two types of sales data processing devices, the store side can implement a service based on the collective rebate system. This batch rebate method is that the store issues a service ticket according to the purchase result periodically and collectively to the customer who became a member, and provides services such as discounts to the customer who brought this service ticket It is. On the other hand, with the latter device,
The store can implement a service based on the immediate rebate method. In the instant rebate method, a discount service according to the purchase performance of the customer is immediately and automatically performed when the purchase of the product is settled.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional sales data processing devices, the price of the product purchased by the customer is simply and uniformly collected irrespective of the type of the product. In this case, the total purchase price is obtained, and the service data corresponding to the total purchase price is output. For this reason, the following inconvenience has occurred.

First, not all customers are members, and in fact, some customers are non-members. Then, in order to increase the effect of attracting customers, a discount service may be provided to specific products for customers other than the members. Also in this case, the above-mentioned conventional sales data processing apparatus processes the specific product, that is, the so-called special price product, as the product targeted for the rebate service without being distinguished from the non-special price product.

For this reason, the member receives further discount processing based on the special price (discount price), and the service becomes excessive, which is not appropriate.

Also, between members, the services of members who shop mainly for bargains and members who do not do so vary in service, which is not appropriate.

Further, according to the above-mentioned conventional sales data processing device, even if there are products whose discounts are regulated by laws or regulations prohibiting discount sales, these regulated products are
Processed as a rebate service target product. As a result,
It may be a substantial discount sale, which may violate laws and regulations,
It is inconvenient.

In addition, when a service clerk issues a service ticket by himself, it is possible to perform a detailed service such as issuing a service ticket twice for a specific product. Cannot simultaneously execute several types of services having different service contents.

The present invention has been made in view of the above circumstances, and has as its object to provide a sales data processing device having a function of providing a service according to a customer's purchase performance in a form according to a store's sales policy. And

[Means for Solving the Problems] The invention according to claim 1 comprises storage means for cumulatively storing the purchase results of a customer who is a member, and after the purchase settlement, stores the contents of the storage means based on the purchase results of the customer. In a sales data processing device that performs a renewal process and performs a rebate service according to the accumulated purchase results stored in the storage means, the product is a service target product for the member corresponding to the identification data of the product.

A means for adding to the cumulative purchase price of the service target product in the memory; and a service price calculation means for calculating the service price (point) based on the cumulative purchase price of the service target product stored in the price memory. The above problem has been solved.

The invention according to claim 2 is provided with storage means for cumulatively storing the purchase results of the customer as a member, and after the purchase settlement, updates the storage contents of this storage means based on the purchase results of the customer and stores the updated contents in the storage means. In a sales data processing device for performing a rebate service in accordance with the stored cumulative purchase results, a unit price memory for storing a unit price or a price of the product corresponding to the product identification data, and a unit price memory corresponding to the product identification data. It is determined whether the product is a service target product for the member. If the product is a service target product, the determination data memory storing determination data indicating the type of service to be provided; and the unit price memory. Means for setting the discrimination data in the discrimination data memory while writing the unit price or price of the product, and inputting customer identification data for identifying the member And means that, for each customer identification data,
The unit price or the price and the discrimination data corresponding to the product identification data are read out from the price memory for storing the total purchase price of the service target product of the member and the unit price memory and the discrimination data memory. Determining means for determining whether or not the product is a service-target product; and, if the determination means determines that the product is a service-target product, a rebate service from the purchase price of the product based on the type of service. Means for calculating a target amount and adding the rebate service target amount to the cumulative purchase price of the service target product in the price memory; and a service price based on the cumulative purchase price of the service target product stored in the price memory. The above problem is solved by providing a service amount calculating means for calculating (point).

* Step SP10 The clerk inputs the PLU number of the product that the customer wants to purchase, for example, “pork loin”. In this case, if the input using the preset key 4 is enabled for the product “pork loin”, the corresponding key of the preset key 4 is pressed to input the PLU number KD. If the input using the preset key 4 is not possible, the input is performed by operating the product number key of the function key 6 and the numeric keypad 5.

◇ Step SP11 When the CPU 21 receives the supply of the PLU number data KD via the operation unit controller 23, the CPU 21 follows the procedure shown in FIG.
The product data is read and displayed. CPU21
First, in step SP111, whether or not the preset key 4 has been pressed, that is,
It is determined whether a PLU number has been input. here,
If "YES" is determined, the process proceeds to step SP112, searches the preset key memory 27g, reads out the corresponding PLU number, and then proceeds to step SP113. On the other hand, step SP1
If it is determined as "NO" in 11, that is, if the PLU number is directly input from the function keys 6 and the ten keys 5, the process proceeds to step SP113. In step SP113, the CPU 21 searches the PLU file 27e, and checks in step SP114 whether the PLU file 27e has a corresponding PLU number. As a result,
If there is a corresponding PLU number, the process proceeds to step SP115, where product data relating to “pork loin” is read and displayed on the first display unit 2a and the second display unit 2b. FIG. 13 shows a display example of product data relating to “pork loin”, for example, “100 g unit price = 250 yen” or the like. On the other hand, if there is no corresponding PLU number, the process proceeds to step SP116,
Display an error message.

* Step SP12 The clerk determines whether or not the product the customer wants to purchase is a weighed product. If the product is a weighed product such as "pork loin", the process proceeds to step SP13.
If the product is a fixed price product, the process proceeds to step SP16.

It should be noted that whether the product is a weighed product or a fixed price product is distinguished by a flag. The unit price is stored in the case of a weighed product, and the price is stored in the case of a fixed price product.

* Step SP13 If the product the customer wants to purchase is a weighed product, the clerk places the product on the weighing dish 1a in a desired amount.
When the product is placed on the weighing dish 1a, the load cell 1b outputs weight data (weighing signal) WD of the product,
The data is sent to the CPU 21 via the load cell controller 20.

Step SP14 Upon receiving the supply of the weight data WD via the load cell controller 20, the CPU 21 executes a purchase price calculation process and a weight / purchase price display process according to the procedure shown in FIG. First, in step SP141, the CPU 21 waits for the supplied weight data WD to stabilize. When the weight data WD is stabilized, the process proceeds to step SP142, where the weighing pan 1a
The unit price (per 1 g) of the above product “pork loin” is multiplied by the weight data WD, for example, “300 g”, and the purchase price of the product “pork loin” is calculated. When the purchase price is calculated, the process proceeds to step SP143, and the weight, the unit price, and the purchase price of the product “pork loin” on the weighing dish 1a are displayed on the first display unit 2a and the second display unit 2b. FIG. 15 shows a display example in step SP143, in which the weight of “pork loin” “300 g”, the purchase price “750 yen”, and the like are displayed.

* Step SP15 Here, if the clerk has obtained the weight placed on the weighing dish 1a as desired by the customer, the clerk proceeds to step SP16.
Proceed to. On the other hand, if the weight desired by the customer has not been obtained, the process returns to step SP13. In this case,
If the amount of goods on the weighing pan 1a has not reached the desired amount (when the weight is insufficient), add more. If the amount exceeds the desired amount (when the weight is excessive), reduce the amount by the excess amount. .

* Step SP16 Here, the clerk presses the "+ A" key of the function key for instructing addition. In addition, the function keys for instructing addition are “+ A” key, “+ B” key,
Four keys, a “+ C” key and a “+ D” key, are provided.
This is to enable simultaneous (parallel) customer service processing for four customers with one device. In this embodiment, a case will be described in which one store clerk handles one customer.

Step SP17 Upon receiving the signal supply from the "+ A" key, the CPU 21 calculates and displays the total purchase price according to the procedure shown in FIG. The CPU 21 first proceeds to step SP1
At 71, the receipt data shown in FIG.
This customer's purchased product data)
After the transfer to d, in step SP172, the total purchase amount and the total number of the customer at the time of the present shopping at this time are calculated. Here, the total number, for example, “3” indicates that the number of executions of step SP16, that is, the number of times the “+ A” key is pressed is three. Next, step SP17
Proceeding to step 3, the result calculated in step SP172, that is, the total purchase amount, for example, “2537” yen, is stored in the receipt buffer 27d, and displayed on the first display unit 2a and the second display unit 2b. FIG. 17 shows a display example in step SP173, in which the total purchase price “2537” yen is displayed.

* Step SP18 If there is still another product that the customer wants to purchase, the process returns to step SP10, and the above process is repeated for the other product that the customer wants to purchase. on the other hand,
If the customer no longer has the item he wants to buy, the clerk asks the customer, "Are you sure you want to enter the checkout process?" And if the customer says "Good," Then, the process proceeds to the next step SP19.

* Step SP19 Here, the clerk asks the customer, "Are you a member of our shop?"
On the other hand, if the customer answers "is a member", the process proceeds to step SP20, and if the customer answers "not a member", the process proceeds to step SP34. Note that the customer in this example is a member.

* Step SP20 Here, the clerk asks the customer, "Do you have a member card (barcode card 17)?" If the customer does not bring a member card, the process proceeds to step SP21. If the customer does bring a member card, the process proceeds to step SP24.

* Step SP21 Here, the clerk presses the "customer" key of function key 6.

Step SP22 When the CPU 21 receives a signal from the "customer" key, the CPU 21 calls the input guide screen shown in FIG. 18 from the screen data file 27h, and displays the first display section 2a and the second display section.
Display on 2b. In the input guide screen, "First, the ten key 5 is operated to input a customer code, and then" customer "
Press the key. Alternatively, first enter the customer's phone number and then press the "↑" key. Is displayed.

* Step SP23 The clerk inputs the customer code heard from the customer or the customer's telephone number according to the input procedure displayed on the input guide screen.

* Step SP24 In step SP20, if the customer has a member card, the clerk receives the member card from the customer and causes the barcode reader 15 to read the customer number (barcode data). In this case, if the membership card cannot be read because the membership card is deformed or damaged,
The clerk executes the processing from step SP21 to step SP23.

SPStep SP25 When the CPU 21 receives the customer number read in step SP24, the customer code input in step SP23, or the customer's telephone number,
According to the procedure shown in the figure, the customer data reading process is executed. First, in step SP251, the CPU 21 determines whether or not a member card input has been made. As a result, "YES"
In this case, the process proceeds to step SP253 to search the customer file 27f for customer data corresponding to the customer number. On the other hand, if “NO”, the process proceeds to step SP252 to determine whether or not a customer code has been input. As a result, in the case of “YES”, the process proceeds to step SP254 to obtain customer data including the customer code, and
Search within. On the other hand, in the case of “NO”, that is, in the case of inputting a telephone number, the process proceeds to step SP255 to search the customer file 27f for customer data including the telephone number. After the search, in step SP256, it is determined whether or not there is corresponding customer data. As a result, if a conclusion of “Yes” is obtained, step SP257
To read the customer data. On the other hand, if a conclusion of “not present” is obtained, the process proceeds to step SP258, where an error message is displayed.

◇ Step SP26 In step SP26, it is determined whether or not today is the customer's birthday according to the procedure shown in FIG. First, in step SP261, the CPU 21 reads, from the clock unit 28, date data indicating the current date, and in the next step SP262, reads the month indicated by the date data and the customer data. It is determined whether or not the recorded “birth month” of the customer matches. At this time, if a negative result is obtained, the process proceeds to step SP29. On the other hand, if a positive result is obtained, the process proceeds to the next step SP263, in which it is determined whether or not the “day” displayed by the date data matches the “birth date” of the customer recorded in the customer data. to decide. At this time, if a negative result is obtained, the process proceeds to step SP29. On the other hand, if a positive result is obtained, the next step SP264
Then, it is determined whether or not shopping has been performed today and a birthday service has been received at that time. If the result of this determination is "YES", the flow proceeds to step SP29. On the other hand, if “NO”, the process proceeds to the next step SP27. It should be noted that whether or not the birthday service has already been received today is determined by storing the customer number of the member who has performed the birthday service on that day.

SPStep SP27 Next, the CPU 21 reads the twenty-first data from the screen data file 27h.
The birthday service message screen shown in the figure is called up and displayed on the first display unit 2a and the second display unit 2b for a certain time and a buzzer sounds. Note that a sound may be emitted instead of the buzzer.

* Step SP28 The clerk presents a souvenir (birthday gift) to the customer whose birthday service message screen is displayed.

◇ Step SP29 In step SP29, calculation / display processing of customer data is performed according to the procedure shown in FIG. CPU21
First, in step SP291, the payment amount for the purchased commodity is calculated, and the calculation result is stored in the payment amount register. Here, the payment amount is obtained by subtracting the rebate amount from the total purchase amount (in this example, “2537” yen). Here, the rebate amount is obtained by adding the rebate amount A and the rebate amount B in the customer data. Next, the presence or absence of the rebate amount A and the rebate amount B is determined (step SP292, step SP293). When the rebate amount A is “Yes”, for example, “300” yen (step S
P292) The process proceeds to step SP294 to clear the rebate target amount memory and the rebate amount A memory in the customer file 27f. When the rebate amount A is "none" (step SP292) and the rebate amount B is "present" (step SP293), the process proceeds to step SP295 and the rebate amount B in the customer file 27f.
Clear memory. When both the rebate amount A and the rebate amount B are “absent” (steps SP292 and SP293), the process immediately proceeds to step SP298, and the display operation of the total purchase amount, that is, the payment amount is executed. Step SP294
Alternatively, after the clearing process in step SP295, the process proceeds to step SP296 to determine whether or not the calculated payment amount is negative. In the case of "minus", the process proceeds to the next step SP297, where the absolute value of the payment amount is stored in the carry-over amount register and the contents of the payment amount register are cleared. After transferring the contents of the carry-over amount register to the rebate amount B memory in the customer file 27f, the process proceeds to the next step SP298, where the total purchase amount, the rebate amount, the carry-over amount and the payment amount are displayed on the first display unit 2a. It is displayed on the second display section 2b. Step SP29
In step 6, if the payment amount is “plus”, the process proceeds to step SP298, and the display operation is immediately executed. FIGS. 23 and 24 show a display example in step SP298. FIG. 23 shows a display example in a case where the payment amount is “plus” in step SP296. In this example, the total purchase amount “ 2537 "yen, rebate amount" 300 "yen, carry-over amount" 0 "yen, and payment amount" 2237 "yen. Also, the 24th
The figure shows a display example when the payment amount is “minus” in step SP296.

* Step SP30 At this point, the clerk looks at the rebate amount column in the displayed customer data and determines whether or not there is a rebate amount.
If the rebate amount is "Yes", proceed to step SP31,
If the rebate amount is not present, the process proceeds to step SP34.
In this example, since the rebate amount is “300” yen, the process proceeds to step SP31.

* Step SP31 Here, the clerk asks the customer whether he / she wants a "full amount" rebate or a "partial" rebate. If "all amount" rebate is desired, the process proceeds to step SP34, and if "partial" rebate is desired, the process proceeds to step SP32.

* Step SP32 Here, the clerk inputs the desired rebate amount, that is, the rebate amount desired by the customer, by operating the ten keys 5 and the "deposit" key of the function keys 6. The input desired rebate amount is stored in the numerical amount register. In addition,
In this example, it is assumed that the customer desires a fraction “37” yen of the total purchase amount “2537” yen as the rebate amount.

◇ Step SP33 In step SP33, the display operation of the rebate result is performed according to the procedure shown in FIG. First, in step SP331, the CPU 21 determines whether or not the desired rebate amount is smaller than the rebate amount. In this example, the desired rebate amount "37" yen is smaller than the rebate amount "300" yen, so the process proceeds to step SP332, and the total purchase amount "2537"
Subtract the desired rebate amount (numerical amount) "37" yen from the yen. When the calculation result ("2500" yen) is obtained, the contents of the payment amount register are stored in the content of the calculation result ("2500").
Yen). Next, in step SP334, a desired rebate amount “37” yen is subtracted from the rebate amount “300” yen. When the calculation result ("263" yen) is obtained, the contents stored in the carry-amount register are stored in the content of the calculation result ("26
3 "circle). Then, the contents stored in the rebate amount B memory and the contents stored in the carry-over amount register in the customer file 27f are added. When the addition result is obtained, the content stored in the rebate amount B memory is rewritten to the addition result. Next, the process proceeds to step SP335, where the total purchase amount, the rebate amount, the carryover amount, the payment amount, and the like are displayed on the first display unit
2a and the second display section 2b. Figure 26 shows the steps
The display example of SP335 is shown, and the total purchase price “2537”
Yen, rebate amount “37” yen, carry-over amount “263” yen and payment amount “2500” yen are displayed. On the other hand, if the CPU 21 determines in step SP331 that the desired rebate amount is larger than the rebate amount, the CPU 21 proceeds to step SP333 and displays an error message.

* Step SP34 Here, the clerk informs the customer of the payment amount. When the clerk receives the deposit amount, for example, "3000" yen from the customer, he enters the deposit amount with ten keys 5 and then "prints".
Press the key.

◇ Step SP35 In step SP35, change calculation / display processing is executed in accordance with the procedure shown in FIG. First, in step SP351, the CPU 21 subtracts the payment amount "2500" from the deposit amount "3000" to calculate the change "500". Next, in step SP352, the change is displayed. FIG. 28 is a display example of change.

{Step SP36} In step SP36, the PLU file 27e and the customer file 27f are updated according to the procedure shown in FIG. First, in step SP361, the CPU 21 initially sets the calling number N of the receipt data to “1”. Next, in step SP362, the “1” -th receipt data in the receipt buffer 27d is read. Next, from the PLU number of the read receipt data, the PLU data such as the total purchase price and the total weight of the product is read from the PLU file 27e. Then, the purchase price and the weight data in the receipt data are respectively added to the total purchase price and the total weight in the PLU data, and the respective cumulative values are obtained. After the addition processing, the stored contents of the total purchase price column and the total weight column in the PLU data are rewritten to the obtained total values.
Next, the process proceeds to step SP363 to determine whether the customer is a member. If “NO”, step SP370
Then, if “YES”, it is determined based on the flag A included in the read receipt data whether the product is a rebate target product that can receive double rebate amount (step SP364). , Step SP365). When the flag A is “2” (step SP364), the process proceeds to step SP366, where the purchase price of the product is multiplied by “2”, and the obtained result is set as a new increase in the rebate target amount. When the flag A is “1” (step SP365), the process proceeds to step SP367, and the purchase price of this product is set as a new increase of the rebate target amount. When the flag A is “0” (step SP365),
Since the product is not a rebate target, the process proceeds to step SP370 without performing the rebate process. After the new increase of the rebate target amount is determined in step SP366 and step SP367, the process proceeds to step SP368, where the customer file 27f
Read the rebate target amount data in the above, add the new increase of the rebate target amount to the read rebate target amount,
Calculate the total value of the rebate target amount. After the calculation, the storage content of the rebate target amount memory in the customer file 27f is rewritten to the calculated total value. Next, the process proceeds to step SP369, where the rebate amount is calculated based on the rewritten rebate amount, and stored in the rebate amount A memory in the customer file 27f. Here, there are a straight-line method and a fixed-rate method as a calculation method of the rebate amount, and any method may be applied. As an example of the fixed amount method, there is an example in which a fixed amount, for example, 1,000 yen is rebated every time the rebate target amount exceeds, for example, 50,000 yen. In addition, as an example of the declining balance method, if the rebate target amount is 10,000 yen or less, 0% of the rebate target amount, 1% if it exceeds 10,000 yen, 2% if it exceeds 20,000 yen
Is used as the rebate amount. Then, in the next step SP370, if this is the last number, the update processing in this step SP36 ends. On the other hand, if this is not the last number, the process proceeds to step SP371, where 1 is added to the calling number N [= 1] to be “2”. Then, the process returns to step SP362 again, and repeats the above processing for the “2” -th receipt data. Thus, after the processing up to the “N” th receipt data is repeated one after another, in step SP370, if the “N” th is the last number, the update processing in step SP36 ends.

◇ Step SP37 In step SP37, receipt printing is executed in accordance with the procedure shown in FIG. First, in step SP372, the CPU 21 initializes the calling number N of the receipt data to “1”. Next, in step SP373, after calling the "1" -th receipt data in the receipt buffer 27d, the "item name", "weight",
The product data such as "purchase price" is transferred to the print buffer 27c, and printed on receipt paper by the thermal printer 8. After the printing is completed, the product data in the receipt bar 27d is cleared. Then, in step SP374,
If this is the last number, the update processing in step SP37 ends. On the other hand, if this is not the last number, the process proceeds to step SP375, where 1 is added to the calling number N [= 1].
To obtain “2”. And again, step SP37
Returning to step 3, the above printing process is repeated for the "2" -th receipt data. In this way, after the processing up to the “N” th receipt data is repeated one after another, step SP374
, If the “N” th is the last number,
Proceed to SP376, "Total purchase amount", "Rebate amount",
The “deposit amount”, “change”, “customer name” and the like are transferred to the print buffer 27c, and are printed by the thermal printer 8 on receipt paper. FIG. 31 shows an example of printing in step SP373 and step SP376.

* Step SP38 Here, the clerk hands the change and receipt to the customer. Thus, all the processes are completed.

According to the above configuration, it is possible to set determination data as to whether or not the product is a rebate target product for each product configuration data (item).
Data for calculating the rebate target amount, that is, how many times the purchase price is set as the rebate target amount can be set. Also, the change is easy. Therefore,
Products to be sold can be arbitrarily classified into non-rebate products, normal rebate products, double rebate products, and the like, and service data corresponding to each can be obtained. Thereby, a more appropriate and detailed rebate service can be implemented. Also, any amount desired by the customer can be rebated within the range of the rebate amount, that is, the rebateable amount. For example, if a fraction of the total purchase price occurs, the customer can request a rebate only for this single unit. Also, the store can reduce the number of complicated bulk change processes, so that the sales process can be speeded up. Also, even if the total purchase price is smaller than the rebateable amount, rebate can be performed only for the total purchase price.

In the above-described embodiment, the case where the flag A (determination data) is input and set by the operation unit 3 has been described, but data may be set online by receiving data online from a store controller or another electronic balance. It is also conceivable to receive and set data from a store controller or another electronic balance via storage means such as a cassette tape recorder or a floppy disk.

Further, the apparatus itself may not have the determination data memory, and may receive the determination data in real time online from a store controller or another apparatus (master) to which a store controller function is added. As described above, a plurality of devices may use a common determination data memory.

Further, in the above-described embodiment, the content of the discrimination data is set to “0”, “1”, and “2” for each PLU data, that is, the rebate target amount is set to 0 times, 1 time, and 2 times the purchase price. Has been described, but the present invention is not limited to this, and may be set to a value (integer) larger than that, or a value (decimal) of, for example, 1.5 times. .

Further, in the above-described embodiment, the case where the rebate target amount does not include the total purchase amount for the current rebate target product is described, but the sum of the purchase total amount for the present rebate target amount is treated as the rebate target amount. You may do it. In the case of handling in this way, even if the rebate target amount up to the previous time is 49,000 yen, if the total purchase price of this time is 1,200, the added value of these is 50,200
A rebate amount is calculated based on the yen.

Further, in the above embodiment, the rest of the rebate amount not used this time is stored as a carry-over amount.However, the carry-over amount is converted into a rebate amount and stored in the form of a rebate amount. May be.

Further, in the above-described embodiment, the case where the service non-execution period is not particularly provided has been described. However, even if the rebate target amount is equal to or more than a predetermined amount, the rebate is not performed during the service non-execution period. , May be performed only during a predetermined service period.

Further, in the above-described embodiment, the case where the customer number is input by using a bar code card has been described. In addition, a customer number can be input using a keyboard. Alternatively, voice input may be used.

Further, in the above-described embodiment, the case where the present invention is applied to the electronic balance is described. However, the present invention is not limited to this case. It can also be applied to systems.

Further, in the above-described embodiment, the case where the PLU number is used as the product identification data is described. However, the present invention is not limited to this, and other codes and numbers may be used as long as they can identify the product. For example, in an ECR system or a POS system, a JAN code by barcode input may be used.

Further, in the above-described embodiment, the case has been described in which the update registration of the product data in the PLU file and the customer data in the customer file is performed at the time of receipt printing. In this way, for example, when the total purchase price is displayed, even if the product is overbought and returned, it is possible to avoid the complexity of correcting the storage contents of the PLU file and the customer file. However, the present invention is not limited to this, and may be performed when data is stored in the receipt buffer.

[Effects of the Invention] As described above, the invention according to claim 1 includes storage means for cumulatively storing purchase results of a customer who is a member, and stores the contents of the storage means after purchase settlement. In a sales data processing device that performs a renewal process based on and performs a rebate service according to the accumulated purchase results stored in the storage means, setting whether or not the product is a rebate service target product for each product Calculate the rebate service amount by automatically excluding discounted products such as bargains and products that are legally prohibited from being discounted, such as cigarettes, without increasing the burden on the clerk. Of purchase results data of customers, which is the basis of the purchase. For this reason, the conventional inconvenience that the service for the member becomes excessive as compared with the non-member or the product for which the discount is prohibited is substantially discounted is solved.

Further, according to the invention described in claim 2, when the product is a product targeted for rebate service, the service target amount of the product (usually the price of the product) is doubled or tripled. The service for a specific product such as an advertising product or a close-out product can be weighted more than the service for another product without increasing the burden on the clerk, and the degree of service can be set for each product. More appropriate and detailed rebate services can be implemented in accordance with the store's sales policy.
