Abstract

PURPOSE:To fixedly reflect a discount to point calculation by calculating points corresponding to a discount when subtotal discount is executed and subtracting the points corresponding to the discount from the total value of points. CONSTITUTION:When a discount corresponding to a subtotal is specified by a discount key 25 and a discount ticket key 26 after depressing a subtotal key 23 on a keyboard 12, the discount is converted into points based upon point reference amount, and the discount points are stored in a discount point accumulating total memory in a RAM 4. In response to totalizing operation based upon a deposit/cash counting key 24, a discount point accumulating value is subtracted from a registered point accumulating value accumulatively stored in a registered point accumulating memory in the RAM 4 to calculate a benefit point. Thereby, the discount corresponding to the subtotal is reflected to the calculation of benefit points and a fixed point discount corresponding to the subtotal discount is executed independently of the point magnification of the registered commodity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device that can automatically calculate bonus points commensurate with the total amount of products purchased by a customer.

[Prior Art] Some retail stores, such as supermarkets and specialty stores, accumulate reward points calculated based on the sales amount of products purchased by customers on memory cards issued to the customers.
Some stores operate stores with the aim of retaining customers by offering services such as prizes based on the cumulative point value stored in the memory card.

Product sales data processing devices such as electronic cash registers used in such stores accumulate the sales amount of products registered for sale through product registration operations in a total amount memory, and store the sales amount in a point reference amount memory. Points are calculated by dividing by a preset point reference amount, and then multiplying the quotient by a predetermined multiplier for the product. Then, through the closing operation, the total amount in the total amount memory is printed on the receipt, the total value of points calculated for each product registration is rounded down to the nearest decimal point, and that value is attached to the card reader/writer as bonus points. A device is known in which the cumulative total is recorded on a memory card.

By the way, one of the services provided to customers is discounts, and the methods of discounting include discounts based on the sales amount of the product, known as product discounts, and discounts based on the customer's total amount (subtotal amount), known as subtotal discounts. However, conventionally, for product discounts, points are calculated based on the sales amount after the discount, and for subtotal discounts, reward points are provided to customers calculated based on the total price before the discount. The reality was that it was happening.

[Problems to be Solved by the Invention] As described above, in the conventional device, the point values calculated for each registration of each product through the tightening operation are totaled and the total value is provided to the customer as bonus points. , the discount amount due to subtotal discount is not reflected in point calculation,
For store openings, there was a problem in that the system provided double services through bonus points and subtotal discounts.

Therefore, the present invention calculates points for the discount amount when a subtotal discount is given, and subtracts the points for the discount amount from the total value of points calculated for each product registration. The present invention aims to provide a product sales data processing device that can uniformly reflect discount amounts in point calculations.

[Means for Solving the Problems] A product sales data processing device of the present invention includes a keyboard provided with at least a number key, a subtotal key, a closing key, and a subtotal discount key for instructing a discount on a subtotal amount; A total amount memory that stores the cumulative sales amount of products registered for sale through a registration operation for one transaction, and a registration point calculation that calculates registered points for the sales amount of products registered for sale through a product registration operation based on point standard values. means, a registered point accumulation memory that stores the registered points calculated by this calculation means for one transaction, and calculates discount points for the subtotal discount amount obtained by operating the subtotal discount key based on the point reference value. a discount point calculation means for calculating the discount points, a discount point accumulation memory for storing the discount points calculated by the calculation means for one transaction; and a discount point accumulation memory for storing the discount points calculated by the calculation means in response to the closing key operation. It is equipped with a point subtraction means for subtracting the cumulative discount point value stored in the discount point cumulative memory from the registered point cumulative value, and a point recording means for recording the point value calculated by the subtraction means. be.

C Effect: With the present invention having such a configuration, when the sale of a product purchased by a customer is registered through the product registration operation, the sales amount of the product is accumulated in the total amount memory, and the registration for the sales amount is Points are calculated and accumulated in the registered point accumulation memory. In this state, when the subtotal key is input, the amount in the total amount memory is displayed as the customer's subtotal amount. Thereafter, when a discount for the subtotal amount is instructed by inputting the subtotal discount key, discount points for the discount amount are calculated and accumulated in the discount point accumulation memory. After that, when the closing key is operated, the discount point cumulative value in the discount point cumulative memory is subtracted from the registered point cumulative value in the registered point cumulative memory to calculate benefit points. For example, the total amount is recorded on a memory card owned by the customer. Therefore, the discount amount due to the subtotal discount will be reflected in the benefit 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 this embodiment, a case will be described in which bonus points calculated based on the sales amount of products purchased by a customer are cumulatively recorded on a magnetic card serving as a memory card issued to the customer. In this case, on the magnetic recording surface of the magnetic card, in addition to the customer code and store code for identifying the customer,
A storage area for reward points is provided.

FIG. 1 is a block diagram of an electronic cash register, in which a CPU (central processing unit) serves as the main control unit.

The ROM 3 stores program data necessary for the CPU to control each section.

The RAM 4 includes various memories used for arithmetic processing by the CPUI. The clock circuit 5 measures the current date and time.

A mode switch 11 is connected to the I10 boat 6 for selecting and specifying various business modes such as "registration,""payment,""inspection," and "setting."
The selection designation signal from 1 is manually input. A keyboard 12 for inputting product sales data manually is connected to the keyboard circuit 7, and key signals from the keyboard 12 are input manually. A display 13 is connected to the display control circuit 8 to display the total sales price of the sold products, etc., and the display 13 is driven to display and output a number or character corresponding to the display data. . Connected to the I10 port 9 are a printer drive circuit 15 that drives the printer 14 to print on receipts and journals, and a drawer opening device 17 that opens the drawer 16.
Outputs the drive signal from. A card reader/writer 18 that reads and writes data to a magnetic card is connected to the card reader/writer control circuit 10, and data is exchanged with the card reader/writer 18.

As shown in FIG. 2, the keyboard 12 has "00
” and number keys 21 from “0” to “9”, and a plurality of department keys 2 in which department codes for classifying each product are preset.
2. In addition to product registration keys such as a subtotal key 23 and a deposit/cash total key 24 as a closing key for cash transactions, a discount key 25 indicating that the number data is the discount amount, and number data. Discount ticket key 26 indicating that is the amount of the discount ticket
, various value quotation keys of a discount key 27 indicating that the set number data is a discount rate are provided.

As shown in FIG. 3, the RAM 4 stores a departmental sales file 31 in which the cumulative number of sales and sales amount of each product is registered for each department code, and a departmental sales file 31 that stores the sales amount of products registered for sale through product registration operations for one transaction. A total amount memory 32 that stores the cumulative total, and a standard amount memory 33 that stores and sets a standard amount as a fixed point standard value used for point calculation.
, a point memory 34 that stores bonus points, a first point work memory 35 as a registered point accumulation memory that stores a total of registered points for one transaction for the sales amount of products registered for sale through product registration operations, and a subtotal key operation. A second point work memory 36 as a memory for accumulating discount points that stores discount points for one transaction for the subtotal discount amount obtained by subsequent price quotation key operations, and a magnetic card is attached to the card reader/writer 10. A flag memory 37 for a card flag CF, which is set (1) when the subtotal flag is set, and a subtotal flag SF, which is set by inputting the subtotal key 23, is formed.

Further, the departmental sales file 31 is provided with a point multiplier area 38 for storing point multipliers set for each department code.

Therefore, the CPUI is set to r by the mode switch 10.
The program is controlled to execute the process shown in the flowchart of FIG. 4 while the registration mode is selected. That is, first, in ST (step) 1, it is determined whether or not a key on the keyboard 12 is being input. If no information has been input, it is determined in ST2 whether or not a magnetic card for accumulating points is attached to the card reader/writer 18. 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 the magnetic card for accumulating points has been inserted into the card reader/writer 18, so after setting the card flag CF, the card reader/writer The card data of the magnetic card read by the writer 18 is taken in, the benefit points in the card data are stored in the point memory 34, and this processing is completed.

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

On the other hand, even if it is detected in ST2 that no magnetic card is attached to the card reader/writer 18, ST4
The state of the card flag CF in the flag memory 37 is checked. If the card flag CF is set, this means that the point accumulation magnetic card attached to the card reader/writer 18 has been removed, so the process is ended after the card flag CF is reset.

On the other hand, if the card flag CF has been reset in ST4, the state in which the point accumulation magnetic card is not attached continues, so this process is ended without doing anything.

When the STI determines that there is a key input from the keyboard 12, an input key signal is taken in via the keyboard circuit 7, and the type of the input key signal is determined. Here, if the input key signal is due to an input operation of the department key 22, it is recognized that the department registration of the product purchased by the customer has been performed, and the department key process shown in FIG. 5 is executed. That is, the sales amount and the number of sales items of this department-registered product are added and registered in the cumulative sales area corresponding to the corresponding department code of the departmental sales file 31. In addition, the corresponding department code and sales amount are displayed on the display 13, and the printer 14
drive to print out information on receipts, etc. Furthermore, the sales amount is added to the total amount 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 multiplier in the point multiplier area corresponding to the corresponding department code to calculate registered points A (registered point calculation means). Then, set this registration point A as the first
is added to the point work memory 35, and this department key processing is completed.

Assuming that the manual key signal is due to a manual operation of the subtotal key 23, it is recognized that the customer's subtotal output power has been instructed, and the subtotal key processing shown in FIG. 6 is executed. That is, first, the contents of the total amount memory 32 are checked. If the amount in the total amount memory 32 is "0" yen, it is determined as an error because the subtotal key operation was performed before the department registration of the product purchased by the customer. The amount in the total amount memory 32 is “
If it is larger than 0'' yen, that amount is determined to be the 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 it on a receipt, etc. Output and end this subtotal key processing.

Assuming that the input key signal is due to an input operation of the discount key 25, it is recognized that a discount has been instructed by the amount entered using the numeric key 21 immediately before, and the value shown in FIG. 7 is generated. Executes pull key processing. That is, first, the subtotal flag SF is checked. If the subtotal flag SF is set, the discount is for the subtotal amount, so the immediately preceding amount is recognized as the discount amount, and the discount amount is subtracted from the total amount memory 32. Next, the discount amount is stored in the standard amount memory 33.
Discount points B are calculated by dividing by the point standard amount within (discount point calculation means). Then, add this discount point B to the second point work memory 36,
This discount key processing ends.

Assuming that the input key signal is due to an input operation of the discount ticket key 26, it is recognized that a discount ticket discount has been instructed by the amount entered using the number key 21 just before, and the process shown in FIG. Executes almost the same process as the discount key process shown. That is, first, the subtotal flag SF is checked. And subtotal flag S
If F is set, it is a discount coupon discount for the subtotal amount, so the amount set immediately before is recognized as the discount amount due to the discount coupon, and the discount amount is subtracted from the total amount memory 32. Next, discount points B are calculated by dividing the discount amount by the point standard amount in the standard amount memory 33 (fii
! Subtraction point calculation method). And this discount point B
is added to the second point work memory 36, and this discount ticket key processing is completed.

If the input key signal is due to the input operation of the discount key 27, it will be recognized that a discount has been instructed at the discount rate entered using the numeric key 21 just before, and the message shown in FIG. Executes almost the same process as the discount key process shown in . That is, first, the subtotal flag SF is checked. If the subtotal flag SF is set, the discount is for the subtotal amount, so the discount amount is calculated by multiplying the amount in the total amount memory 32 by the discount rate set immediately before, and the discount amount is calculated from the total amount memory 32. Subtract the discount amount. Next, the discount point B is calculated by dividing the discount amount by the point standard amount in the standard amount memory 33 (discount point calculation means). Then, this discount point B is added to the second point work memory 36, and this discount key processing is completed.

In addition, in each key process of the above-mentioned discount key 251, discount ticket key 26, and discount key 27, if the subtotal flag SF is reset, the discount is for the product that was registered for sale immediately before, so the same procedure as before is applied. Execute the corresponding product discount process.

If the input key signal is an input operation of the deposit/account key 24, it is recognized that an instruction has been given to close the registration by cash transaction, and the deposit/account key process shown in FIG. 8 is executed. That is, first, the subtotal flag SF is checked. If the subtotal flag SF had been reset, the deposit/cash total key 24 was inputted before the subtotal amount was calculated, so an error is determined. After confirming that the subtotal flag SF is set, first, the first point work memory 35
The discount point cumulative value in the second point work memory 36 is subtracted from the registered point cumulative value in the second point work memory 36 (point subtraction means). Then, the point value obtained by this subtraction means is rounded down to the decimal point, and the value is set as a bonus point, and this bonus 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, an instruction is given to write the accumulated value of reward points in the point memory 34 to this magnetic card. (
point recording means). Thereafter, change calculation, receipt issuing, drawer opening, etc. are performed as normal deposit closing processing, and this deposit/cash key processing is completed.

In addition, the total amount memory 32, the point memory 34,
1st. The second point work memories 35 and 36 are cleared after the above-mentioned deposit closing process is completed.

In this embodiment configured as described above, each customer carries out shopping by bringing a magnetic card issued by the store for accumulating points. Then, when paying the bill, the customer hands his or her magnetic card to the clerk. After receiving the magnetic card from the customer, the clerk attaches the magnetic card to the card reader/writer 10 of the electronic cash register, and then presses the number key 2 on the keyboard 12.
1 and department key 22 to register the department of the product purchased by the customer. Then, the registered points A for the sales amount of the department registered product are calculated based on the point standard amount in the standard amount memory 33 and the point multiplier corresponding to the corresponding department code, and the registered points A of each product are stored in the first point work memory 35. It is accumulated in .

When the department registration for all the customer's products is completed, the clerk operates the subtotal key 23 to input. Then, the amount in the total amount memory 32 is displayed as a subtotal amount. here,
When the customer pays in cash an amount commensurate with this subtotal amount, the clerk enters the payment amount using the number keys 21 and then inputs the deposit/cash total key 24. Then, since the content of the second point work memory 36 is "0", the registered point cumulative value accumulated in the first point work memory 35 is cumulatively recorded as privilege points on the magnetic card held by the customer.

On the other hand, when the customer presents a discount coupon of a predetermined amount after operating the subtotal key 23, the clerk enters the amount of the discount coupon using the number key 21 and then inputs the discount coupon key 26. Then, the discount coupon amount is discounted from the subtotal amount, and discount points B for this discount coupon amount are calculated based on the point reference amount, and the second point work memory 36
is stored in In addition, when giving a discount or a 96% discount to the subtotal amount as one of the services provided to the customer, the clerk enters the discount amount or discount rate and then presses the discount key 25.
Alternatively, the user inputs the discount key 27. Then, a discount will be applied from the subtotal amount, and discount points will be calculated for the point standard amount of the discount amount, and the second
is added to the point work memory 36. If the customer pays in cash the amount commensurate with the subtotal amount after the discount,
After entering the amount to be paid, the clerk operates the deposit/total key 24 to input the amount. Then, the cumulative discount point 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 privilege points on the magnetic card held by the customer. be done.

Now, let's assume that the point standard amount is 100 yen (one point is given for every 100 yen amount), and for example, the point multiplier is 3.
Suppose that a customer purchases product M with a sales price of 1,999 yen that belongs to the department code [o1] with a point multiplier of 1x, and product N with a sales price of 2,999 yen that belongs to the department code [o3] with a point multiplier of 1x. The cumulative registered point value is 89.96. Here, if a discount of 1000 yen is given to the customer's subtotal amount (4998 yen), and the customer uses a 500 yen discount coupon, the cumulative discount point value for this customer is 15. It becomes .00. Therefore, the reward points for this customer are rounded down to 74 points after the decimal point. Previously, the cumulative value of registered points was rounded down to the nearest whole number.
i! (89 points) are given as bonus points,
Points were awarded for amounts that were larger than the customer's actual total.

According to this embodiment, when a discount amount for the subtotal amount is instructed by the discount key 251 discount ticket key 26 or discount key 27 after operating the subtotal key 23, the discount amount is converted into points using the point standard amount. and is accumulated in the second point work memory 36 as discount points.

Then, in response to the closing operation using the deposit/cash total key 24, the discount point cumulative value is subtracted from the registered point cumulative value stored in the first point work memory 35 to calculate privilege points. Therefore, the discount amount on the subtotal amount is reflected in the calculation of reward points, and
Regardless of the point multiplier of registered products, a certain point reduction will be made to the subtotal discount amount. This prevents the inconvenience of providing dual services to store opening customers with bonus points and subtotal discounts. However, points are reduced fairly to all customers through subtotal discounts, so there is no risk of customers complaining.

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

In the above embodiment, a magnetic card was used as the point accumulating card, but it goes without saying that an IC card can also be used by using an IC card interface in place of the card reader/writer 18. Further, in the above embodiment, the case where the reward points for each customer are accumulated on a memory card (magnetic card) is shown, but it may be made to be accumulated on an internal memory. Alternatively, the system may be of a type in which bonus points are printed and recorded on the receipt for each transaction and are not accumulated in the memory medium.

It should be noted that the electronic cash register of the above embodiment is used as PO3.
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 created in a higher-level controller.

[Effects of the Invention] As detailed above, according to the present invention, when a subtotal discount is given, points are calculated for the discount amount, and the points are calculated from the total value of points calculated for each product registration. By subtracting points from the discount amount, it is possible to provide a product sales data processing device that can uniformly reflect the discount amount due to subtotal discount in point calculation with a simple configuration.
