Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a product sales data processing device capable of automatically calculating privilege points commensurate with a total price of products purchased by a customer.

[Prior Art] Some retail stores, such as supermarkets and specialty stores,
The reward points calculated based on the sales amount of the product purchased by the customer are cumulatively stored in the memory card issued to the customer, and the service such as a gift is provided by the cumulative point value stored in the memory card. There are some stores that are operating with the aim of retaining customers.

As a product sales data processing device such as an electronic cash register used in such a store, the sales amount of the products registered by the product registration operation is accumulated in the total amount memory, and the sales amount is calculated as the point reference amount memory. Is divided by a point reference amount set in advance, and the quotient is multiplied by a predetermined multiplying factor to calculate points. Then, by tightening, the total amount in the total amount memory is printed on the receipt, and the total value of the points calculated for each product registration is rounded down, for example, after the decimal point, and that value is attached to the card reader / writer as a privilege point. It is known that a memory card is used for cumulative recording.

By the way, there is a discount as one of the services to customers,
As the discount method, there are a so-called product discount and a so-called subtotal discount for the total amount of money (subtotal amount) of the customer, which is conventionally the product discount after the discount. In the actual situation, the points are calculated for the sales amount of, and for the subtotal discount, the privilege points calculated for the total amount before the discount are provided to the customer.

[Problems to be Solved by the Invention] As described above, in the conventional device, the point values calculated for each registration of each product by the tightening operation are totaled and the total value is provided to the customer as privilege points. However, the discount amount due to the subtotal discount is not reflected in the point calculation, and there is a problem that the store side provides a double service of a privilege point and a subtotal discount.

Therefore, the present invention calculates the point for the discount amount when the subtotal discount is performed, and subtracts the point for the discount amount from the total value of the points calculated for each registration of each product, thereby reducing the subtotal discount. An object of the present invention is to provide a product sales data processing device capable of constantly reflecting the discount amount due to the points calculation.

[Means for Solving the Problem] The present invention provides a registration means for registering data of sales commodities, a total amount memory for totaling one transaction of sales amount data of each sales commodity registered by the registration means, and one transaction. Subtotal key for instructing subtotal output of each registered sale product, 1
It has a subtotal discount key for entering the discount amount for the subtotal amount of the transaction, and a closing key for declaring the end of registration of one transaction. When the subtotal key is entered, the data in the total amount memory is output as the subtotal amount, and the subtotal When the discount key is entered, the discount amount is deducted from the data in the total amount memory, and when the closing key is entered, the data in the total amount memory is used as the total amount for the closing process. Each time the data of the sale item is registered by the means, the registration point calculation means for calculating the registration point from the sale price of the commodity and the preset point reference value, and the registration points calculated by the calculation means are made one transaction. Every time the discount amount for the subtotal amount is entered with the total memory of registered points for totaling the minutes and the subtotal discount key, the discount point and the point standard are used for the discount point. A discount point calculation means for calculating the door, a discount point is calculated by the calculator 1
A discount point total memory for totaling transactions, and point subtraction means for subtracting the point data in the discount point total memory from the point data in the registered point total memory when the registration end of one transaction is declared by the closing key. ,
The point data calculated by this subtraction means
It is provided with point recording means for recording as privilege points for transactions.

[Operation] According to the present invention having such a configuration, the registration means 1
After the data of all the products sold by one customer are registered,
When the subtotal key is entered, the total price memory stores the total price of all products for sale. Moreover, the total value of the registration points calculated for all the sold products is stored in the registration point total memory. Next, when the discount amount for the subtotal amount is entered with the subtotal discount key, the discount amount is reduced from the data in the total amount memory, and the discount points for this discount amount are calculated, and the total discount point memory Stored in. Then, when the registration end of one transaction is declared by the closing key, the closing processing is performed with the data in the total amount memory as the total amount, and the discount point total is calculated from the point data in the registered point total memory. The point data in the memory is subtracted to calculate bonus points for one transaction, and the bonus points are cumulatively recorded in, for example, a memory card owned by the customer. Therefore, the discount amount due to the subtotal discount is reflected in the privilege points provided to the customer.

[Embodiment] An embodiment in which the present invention is applied to a single electronic cash register will be described below. In the present embodiment, a case will be described in which the privilege points calculated based on the sales price of the product purchased by the customer are cumulatively recorded in a magnetic card as a memory card issued to the customer.

There is formed a card flag CF that is set (1) when a magnetic card is attached to the card and a flag memory 37 for the subtotal flag SF that is set by the input operation of the subtotal key 23.

Further, the sales file 31 for each section is provided with a point multiplication area 38 for storing the point multiplication set for each division code.

Therefore, the CPU 1 is program-controlled so as to execute the processing shown in the flowchart of FIG. 4 in a state where the "register" mode is selected by the mode switch 10. That is, first, as ST (step) 1, it is determined whether or not the key of the keyboard 12 is input. If it is not input, the card reader / writer 18
It is determined whether or not a magnetic card for accumulating points is installed. Here, when it is detected that a magnetic card for accumulating points is attached to the card reader / writer 18, the state of the card flag CF in the flag memory 37 is checked in ST3. If the card flag CF has been reset, it means that a magnetic card for accumulating points has been attached to the card reader / writer 18, so after setting the card flag CF, the card reader / writer control circuit 10 is used to read the card reader / writer. The card data of the magnetic card read by the writer 18 is taken in, the privilege points in the card data are stored in the point memory 34, and this processing ends.

On the other hand, if the card flag CF is set in ST3, the magnetic card for accumulating points continues to be attached, and this process ends without doing anything.

On the other hand, if it is detected in ST2 that no magnetic card is attached to the card reader / writer 18, the state of the card flag CF in the flag memory 37 is checked in ST4. If the card flag CF is set, the magnetic card for accumulating points accumulated in the card reader / writer 18 has just been removed.
After resetting, this process is completed.

On the other hand, if the card flag CF is reset in ST4, the magnetic card for accumulating points continues to be unmounted, and this process ends without doing anything.

When it is determined in ST1 that there is a key input from the keyboard 12, the input key signal is taken in through the keyboard circuit 7 and the type of the input key signal is determined. Here, if the input key signal is based on the input operation of the department key 22, it is recognized that the department of the product purchased by the customer has been registered, and the department key processing shown in FIG. 5 is executed. That is, the sales amount and the number of sales points of the section-registered product are added and registered in the cumulative sales area corresponding to the corresponding section code of the section-specific sales file 31. Further, the corresponding department code and the sales amount are displayed on the display 13 and the printer 14 is driven to print out on a receipt or the like. Further, the sales amount is added to the total amount memory 32. Next, the sales amount is divided by the reference amount in the reference amount memory 33, and the quotient is multiplied by the point multiplying factor in the point multiplying area corresponding to the relevant department code to calculate the registration point A (registered point calculating means). Then, this registration point A is added to the first point work memory 35, and this department key processing is ended.

If the input key signal is due to the input operation of the subtotal key 23, it is recognized that the customer's subtotal output is instructed, and the subtotal key processing shown in FIG. 6 is executed. That is, first, the contents of the total amount memory 32 are examined. Then, if the amount of money in the total amount of money memory 32 is "0" yen, it is an error because the subtotal key operation was performed before the division registration of the product purchased by the customer was performed. The amount in the total amount memory 32 is "0"
If the amount is larger than the yen, the amount is judged to be a subtotal amount, and after setting the subtotal flag SF in the flag memory 37, the subtotal amount is displayed on the display 13 and the printer 14 is driven to print out on a receipt or the like. Then, the subtotal key processing is ended.

If the input key signal is due to the input operation of the discount key 25, the value shown in FIG. Execute the pull key process. That is, first, the subtotal flag SF is checked. Then, if the subtotal flag SF is set, the amount is discounted to the subtotal amount. Therefore, the amount of money that has been registered immediately before is recognized as the discount amount, and the discount amount is subtracted from the total amount memory 32. Next, the discount amount is divided by the point reference amount in the reference amount memory 33 to calculate the discount point B (discount point calculating means). Then, the discount point B is added to the second point work memory 36, and the discount key processing is ended.

If the input key signal is due to the input operation of the discount ticket key 26, it is recognized that the discount ticket discount is instructed by the numerical value entered by the numeral key 21 immediately before, and the result is shown in FIG. Almost the same processing as the discount key processing shown is executed. That is,
First, check the subtotal flag SF. Then, if the subtotal flag SF is set, it is a discount voucher discount for the subtotal amount. Therefore, the amount of money registered immediately before is recognized as the discount amount due to the discount voucher, and the discount amount is subtracted from the total amount memory 32. . Next, the discount amount is divided by the point reference amount in the reference amount memory 33 to calculate the discount point B (discount point calculating means). Then, the discount point B is added to the second point work memory 36, and the discount ticket key processing is ended.

If the input key signal is due to the input operation of the discount key 27, it is recognized that the discount at the discount rate entered by the numeric key 21 was instructed immediately before, and it is also shown in FIG. A process similar to the discount key process is executed. That is,
First, check the subtotal flag SF. Then, if the subtotal flag SF is set, it is a discount for the subtotal amount, so the amount in the total amount memory 32 is multiplied by the discount rate that has been entered immediately before to calculate the discount amount. Subtract the discount amount. Next, the discount amount is divided by the point reference amount in the reference amount memory 33 to calculate the discount point B (discount point calculating means). Then, the discount point B is added to the second point work memory 36, and the discount key process is terminated.

The discount key 25, discount ticket key 26 and discount key 2 above
In each key process of 7, when the subtotal flag SF is reset, since the discount is on the product registered for sale immediately before, the corresponding product discount process is executed in the same manner as in the past.

If the input key signal is based on the input operation of the deposit / cash total key 24, it is recognized that the registration closing by the cash transaction is instructed, and the deposit / cash total key processing shown in FIG. 8 is executed. That is, first, the subtotal flag SF is checked. And
If the subtotal flag SF has been reset, it is an error because the deposit / cash total key 24 has been operated before the subtotal amount was calculated. When it is confirmed that the subtotal flag SF is set, first, the point data in the second point work memory 36 is subtracted from the point data in the first point work memory 35 (point subtraction means). Then, the value obtained by rounding down the decimal point of the point value obtained by the subtraction means is defined as a privilege point, and this privilege point is added to the point memory 34. Next, if the card flag CF is set, since a magnetic card for accumulating points is attached to the card reader / writer 10, the writing of the privilege point accumulated value in the point memory 34 is instructed to this magnetic card. (Point recording means). afterwards,
Change calculation, receipt issuance,
After opening the drawer, etc., the deposit / cash total key processing is completed.

The total amount memory 32, point memory 34,
The first and second point work memories 35 and 36 are cleared after the above-mentioned custody process is completed. The subtotal flag SF is also reset.

In the present embodiment configured as described above, each customer carries out shopping by bringing a magnetic card for accumulating points issued from the store. Then, when carrying out the accounting, he hands his magnetic card to the clerk. The store clerk who receives the magnetic card from the customer installs the magnetic card in the card reader / writer 10 of the electronic cash register, and then operates the number key 21 and the department key 22 of the keyboard 12 to operate the department of the product purchased by the customer Perform registration operation. Then, the registration point A for the sales amount of the department registered product is calculated by the point reference amount in the reference amount memory 33 and the point multiplication factor corresponding to the relevant department code, and the registration point A of each product is the first.
It is accumulated in the point work memory 35 of.

When the department registration is completed for all the products of the customer, the clerk operates the subtotal key 23. Then, the amount in the total amount memory 32 is displayed as the subtotal amount. Here, when the customer pays the amount corresponding to this sub-total amount in cash, the clerk enters the deposit amount with the numeric key 21 and then deposit / cash total key.
Input 24. Then, since the content of the second point work memory 36 is "0", the cumulative total of registered points in the first point work memory 35 is cumulatively recorded as a privilege point in the magnetic card possessed by the customer.

On the other hand, when the customer presents a discount voucher of a predetermined amount after operating the subtotal key 23, the clerk enters the amount of the discount voucher with the numeric key 21 and then inputs the discount voucher key 26. Then, the discount ticket amount is discounted from the subtotal amount, and the discount point B for the discount ticket amount is calculated based on the point reference amount and stored in the second point work memory 36. In addition, when discounting or% discounting the subtotal as one of the services to customers, the clerk enters the discount key 25 or the discount key 27 after entering the discount amount or the discount rate. To do. Then, the discount is also performed from the subtotal amount, and the discount point for the point reference amount of the discount amount is calculated and added to the second point work memory 36. Here, when the customer pays in cash an amount commensurate with the discounted subtotal amount, the clerk enters the deposit amount and then inputs the deposit / cash total key 24. Then, the discounted point cumulative value in the second point work memory 36 is subtracted from the registered point cumulative value in the first point work memory 35, and the value is cumulatively recorded as a privilege point in the magnetic card possessed by the customer. To be done.

Now, assuming that the point reference amount is 100 yen (one point is given for 100 yen), for example, a product M with a sales amount of 1999 yen belonging to the department code [01] with a point multiplication factor of 3,
Sales amount belonging to the department code [03] with a point multiplication factor of 1
If there is a customer who purchased the product N of 2999 yen, the cumulative registration point value of the customer is 89.96. Here, if a discount of 1000 yen is given to the subtotal (4998 yen) of the customer and the customer uses a discount ticket of 500 yen, the cumulative discount point value of this customer is 15.00. Become. Therefore, the privilege points for this customer are rounded down to the nearest whole number.
74 points. In the past, the value (89 points) that was rounded down to the nearest whole number of registered points was given as privilege points, and points were given to larger amounts than the actual total amount of customers.

As described above, according to the present embodiment, when the discount key 25, the discount ticket key 26, or the discount key 27 indicates the discount amount for the subtotal amount after the operation of the subtotal key 23, the discount amount is pointed by the point reference amount. The converted points are accumulated as discount points in the second point work memory 36. And
In response to the tightening operation with the deposit / cash total key 24, the discount point cumulative value is subtracted from the registered point cumulative value cumulatively stored in the first point work memory 35 to calculate the privilege points. Therefore, the discount amount for the subtotal amount is reflected in the calculation of the privilege points, and a certain point reduction is made for the subtotal discount amount regardless of the point multiplication factor of the registered product. Therefore, it is possible to prevent a problem that the store side provides the customer with a double service of a privilege point and a subtotal discount. Moreover, since all customers will be able to fairly reduce points by subtotal discounts, there is no risk of customers complaining.

In addition, it is a simple calculation that you can calculate the discount point cumulative value for the subtotal discount amount by the same calculation method as the registered point cumulative value and subtract the discount point cumulative value from the registered point cumulative value after the closing operation. Since it can be realized, the program processing does not become complicated and can be processed in a short time.

In addition, in the above-mentioned embodiment, a magnetic card is illustrated as the card for accumulating points, but instead of the card reader / writer 18,
It goes without saying that it can be applied to an IC card by using the IC card interface. Also,
In the above-mentioned embodiment, the case where the privilege points for each customer are accumulated in the memory card (magnetic card) has been described, but it may be accumulated in the internal memory. In addition, the reward points will be printed and recorded for each transaction,
It may be of a type that does not accumulate in the memory medium.

In addition, the electronic cash register of the above-mentioned embodiment is POS
Of course, it can also be applied as a terminal in a (point-of-sale information management) system. In this case, the departmental sales file 31 may be formed in the upper controller.

[Effects of the Invention] As described in detail above, according to the present invention, when a subtotal discount is made, points for the discount amount are calculated,
A product sales data processing device that can reflect the discount amount due to the subtotal discount to the point calculation with a simple configuration by subtracting the points for the discount amount from the total value of the points calculated for each registration of each product it can.
