Abstract

PURPOSE:To lighten a burden on a casher by accumulating and recording points calculated for a sales total amount and executing discounting processing accord ing to this accumulated points on a memory card. CONSTITUTION:When discounting data are inputted by a discounting data input means 16 under a state in which the total amount of a customer at this time is calculated in a sales counter 42, a discounting amount corresponding to the discounting data is reduced from the amount in the sales counter 42, and points corresponding to the discounting data are subtracted from an accumulated point memory 43. When an adding up key is operated after that, the points corresponding to the discounted sales amount are calculated and added to the subtracted accumulated points in the accumulated point memory 43, and a memory card 8 is ejected after this accumulated points after the adding and the updating are written onto the memory card 8. Thus, the burden on the casher can be lightened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in a store that calculates a certain ratio of points based on the total amount of purchases and gives benefits to customers based on the cumulative number of points. This invention relates to electronic cash registers.

[Conventional technology] In order to retain customers who frequently visit the store, some stores and supermarkets, for example, offer discounts to customers who have purchased more than a standard amount in their previous purchases. Some stores issue service coupons with points multiplied by a certain percentage, and when the customer submits the service coupon the next time they shop, the amount equivalent to the service coupon will be discounted from the total price. At such stores, the operator of the electronic cash register (cashier) asks customers whether or not they have submitted a service ticket each time they register a sale, and if a service ticket is submitted, the value is calculated based on the points. The closing key was operated after calculating the discount amount and registering the discount.

[Problem to be solved by the invention] However, in this case, the customer must himself manage the service coupons that are issued each time he makes a purchase that exceeds the standard amount.
Not only does this create a sense of complication for the customer, but there is also the risk that the customer may lose the service ticket, so it cannot be said that the service quality is sufficient. In addition, the cashier has to issue service coupons according to the total amount of sales, and also has to calculate the discount amount when payment is made using a service coupon, which is a heavy burden.

This kind of problem can be solved by having the customer carry a memory card, and instead of issuing a service ticket, the points of the service ticket are accumulated on the memory card, and discounts can be processed according to the accumulated points of this memory card. It can be solved by doing so.

Therefore, the present invention enables points calculated for the total amount of sales to be accumulated and recorded on a memory card, and discount processing can be easily performed according to the accumulated points of this memory card, thereby further improving serviceability. The present invention also aims to provide an electronic cash register that can reduce the burden on cashiers.

[Means for Solving the Problems] The present invention cumulatively registers the sales data of each sales product input through the input unit in the storage unit, adds up the sales amount with a sales totalizer, and operates the key operation. A card reader that writes/reads the cumulative points from an inserted memory card in an electronic cash register that responds to print out sales data and the total amount and also clears the sales totalizer. A writer, a cumulative point memory for storing cumulative points read by the card reader/writer, a discount data input means, and a sales totalizer when discount data is input by the discount means before the closing key is operated. a discount processing means that subtracts the discount amount corresponding to the discount data from the amount of the discount data, and subtracts the points corresponding to the discount data from the cumulative points in the cumulative point memory; and the sales total in response to the closing key operation. A point calculation means for calculating points corresponding to the amount in the device, and a point calculation means for adding and updating the points calculated by this calculation means to the cumulative points in the cumulative point memory, and writing them to the memory card inserted in the card reader/writer. and cumulative point update processing means.

[Function] With an electronic cash register that takes such measures, when a customer inserts a memory card brought into the card reader/writer, the customer's cumulative points up to the previous time are read and stored in the cumulative point memory. . Then, when the customer's current total amount is calculated in the sales totalizer, if you operate the closing key, points are calculated from the total amount and added to the cumulative points in the cumulative point memory, and after this addition is updated. The card is ejected after the accumulated points have been written to the memory card.

On the other hand, when the customer's current total amount is calculated in the sales totalizer, if discount data is input using the discount data input means, the discount amount corresponding to the discount data will be calculated from the amount in the sales totalizer. is reduced, and the points corresponding to the discount data are subtracted from the cumulative point memory. After that, when you press the close key, points corresponding to the discounted sales amount are calculated and added to the subtracted cumulative points in the cumulative point memory, and the updated cumulative points are written to the memory card. The card is then ejected.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the external configuration of the electronic cash register of this embodiment. As shown in the figure, a keyboard 2 for inputting sales data of each sales item is provided in the center of the front of the housing 1. A cashier's display 3 is provided at the upper part of the front surface for electronically displaying the sales amount, total amount, etc. of each sales item manually entered. Further, a receipt issuing port 4 is formed in the center of the front surface of the housing 1 adjacent to the keyboard 2. A drawer 5 for storing cash and the like is installed on the lower surface of the housing 1, and a customer display 6 having the same configuration as the cashier display 3 is attached on the upper surface of the housing 1.

Further, a card reader/writer 7 is attached to the lower side of the cashier display 3 for reading and writing card data to a memory card 8 constituted by a magnetic card.

The card used in this electronic cash register is issued by the store to customers who come to shop, and the magnetic stripe 8a of this card has the following information as shown in Figure 2.
At least an area M1 for storing a membership number set for each customer and an area M2 for accumulating points calculated corresponding to sales amounts are formed. At the time of card issuance, "0" is stored in the cumulative point area 2.

As shown in FIG. 3, the keyboard 2 includes a number key 11 for inputting the sales amount of the sold product, a department key 12 for inputting the department to which the sold product belongs, and a subtotal key 12 for calculating the subtotal amount. In addition to product registration keys such as the subtotal key 13 for cash payment, and the deposit/cash total key 14 as a closing key for instructing registration details by cash payment, the sales registration uses the memory card 8 of this embodiment. Various function keys are provided, such as a card key 15 for commanding , and a discount key 16 for inputting discount data.

In addition, on the keyboard 2 above, you can control the power on/off, as well as "Register", "Payment", "Settings", and "Inspection".
A control key 17 is provided for selecting various business modes such as , etc., and instructing the central processing unit to execute the mode.

FIG. 4 is a block diagram showing the internal configuration of the electronic cash register. In the figure, reference numeral 21 denotes a central processing unit (hereinafter abbreviated as CPU), which incorporates an arithmetic circuit, a memory control circuit, etc., and performs predetermined arithmetic processing according to various input data. ROM2 that stores programs, etc. for executing each of the above-mentioned tasks;
B, and RAM 24 as a storage unit for registering sales data.
and operate. - Also, the I10 port 25 sends and receives command signals from the control key 17 and card data to the card reader/writer 7, the printer drive circuit 27 of the printer 26 that prints on receipts, and the drawer opening device 28 of the drawer 5. Two I10 boats that send drive signals, a display controller 30 that sends drive signals to each display 3.6, a keyboard controller 31 that inputs key signals from the keyboard 2, and a drive signal to the buzzer drive circuit 33 of the buzzer 32. An I10 boat 34 for sending data, a transmission control circuit 35 for communicating with an upper host computer (HC) via an inline line, and the like are connected to the CPU 21 via the path line 22.

As shown in FIG. 5, the RAM 24 stores a sales registration file 41 for accumulating sales data such as the number of sales items and sales amount of registered products by department, transaction, etc.
A sales totalizer 42 that calculates the total amount of products sold to customers, and a cumulative point memory 4 that stores the cumulative points read from the card 8 inserted into the card reader/writer 7.
3. A standard amount memory 44 for storing a standard amount for calculating points for one total amount, a discount amount memory 45 for storing a discount amount input by key operation of the discount key 16, and Work memories 46A, 46B, etc. used for arithmetic processing are formed.

After the CPU 21 executes a predetermined initial process when the power is turned on, when the control key 17 is set to the "registration" mode, the CPU 21 performs the sales registration process for the customer using the card 8 according to the flowchart shown in FIG. The program is configured to run. That is, when the card key 15 is input at Pl and the card 8 is inserted into the card reader/writer 7 at P2, the card reader/writer will read the membership number, cumulative points, etc. stored in the magnetic stripe section 8. The card information is read and sent to the host computer via the transmission control circuit 35 to confirm the reliability of the card. Then, if the reliability is confirmed in P3, the cumulative points of the read card information are stored in the cumulative point memory 43 of the RAM 24.

Next, when sales data such as the sales amount of the sales item and the department code is input via the keyboard 2 at P4, this sales data is registered in the sales registration file 41 by department code, and the sales amount is calculated as the sales total. 42. Further, the department code and sales amount are displayed on the displays 3 and 6 and printed out on a receipt by the printer 26.

Thereafter, when the subtotal key 13 is pressed manually at P5, the total amount calculated by the sales totalizer 42 is displayed on the display 3.6 and is printed out on the receipt. Subsequently, when the discount key 16 is pressed after entering the discount amount in P6, the discount amount is stored in the discount amount memory 45 and printed on the receipt. Next, the discount amount memory 45 is calculated from the cumulative points of the card 8 stored in the cumulative point memory 43.
The cumulative points after discount processing are calculated by subtracting the discount amount in , and these points are stored in the work memory 46A. Then, it is checked whether the point in the work memory 46A is 0 or more, and if it is negative, an error occurs and the buzzer 3
2 to indicate that discounts are not possible. On the other hand, if the points in the work memory 46A are 0 or more, the discount is permitted and the data in the cumulative point memory 43 is rewritten to the points in the work memory 46A.

Further, the contents of the sales totalizer 42 are rewritten to the amount obtained by subtracting the discount amount in the discount amount memory 45.

After that, when the deposit/cash key 14 is input on Pl,
At step 8, the total amount in the sales totalizer 42 is accumulated for each cash transaction in the sales registration file 41, and is printed out on a receipt. Further, by dividing this sales amount by the standard amount in the standard amount memory 44, points corresponding to the current sales amount are calculated and stored in the work memory 46B. Next, the points in the work memory 46B are added to the cumulative points in the cumulative point memory 43 to calculate a new cumulative point, and the contents of the cumulative point memory 43 are rewritten to the new cumulative points. Then, the new accumulated points are printed out on a receipt, and this receipt is issued from the receipt issuing port 4.

Next, the new cumulative points in the cumulative point memory 43 are written in the area M2 of the magnetic stripe portion 8a of the card 8 by the card reader/writer, and the card 8 is ejected. After that, the sales totalizer 42, the cumulative point memory 43. The discount amount memory 45 and work memory 46 are cleared and the process ends.

On the other hand, if there is no key power for the discount key 16 at P6 and the deposit/total key 14 is input at Pl, the same processing as that from P8 described above is executed and the process ends.

When using the electronic cash register of this embodiment configured in this way at a store that provides points ``1'', which is equivalent to 1 yen for a single sale of ``100 yen'', it is necessary to set the standard amount in advance. A reference amount "100 yen" is set in the memory 44. Now, if a customer comes to checkout at this store with Card 8, which has already accumulated R650J of points from previous purchases, the cashier receives Card 8 from the customer, inserts it into the card reader writer, and holds the card key. Enter 15. Then, after the reliability check of the card 8 is performed, the cumulative points r650J of this card 8 are stored in the cumulative point memory 43. Thereafter, the cashier operates the keyboard 2 to register the products purchased by this customer. For example, r10'00Jr division 1", "20
00""Department 2J, r3000J rDepartment 3" and then operate the subtotal key 13, the total amount in the sales totalizer 42 "r6000 yen" will be displayed on the display 3.6 and will be printed on the receipt. Ru.

Here, the cashier asks the customer whether or not he or she would like to receive a discount based on the accumulated points. If the customer does not wish for a discount, he or she operates the deposit/total key 14. Then,
The total amount of cash transaction r6,000 yen" is printed, and this total amount of r6,000J yen and the standard amount of r100 are printed.
Points "60" are calculated from J yen, and these points "60" are added to the previous cumulative points r650J to calculate new cumulative points r710J. Then, this new cumulative point r710J is printed on the receipt, and the receipt is issued.

Further, this new cumulative point r710J is written in area M2 of the card 8, and the card 8 is ejected. The cashier then hands the receipt and card 8 to the customer in exchange for the payment of r6000J yen.

On the other hand, if a customer desires a discount, the desired discount amount (
After inputting a number (for example, 600 yen), the discount key 16 is operated. Then, the discount amount r600J is subtracted from the point r650J in the cumulative point memory 43, and this difference is
50" is more than 0, so discount is allowed, and this difference "5o"
is stored in the cumulative point memory 43. In addition, the discount amount is r600 yen from the sales total 42 amount r6000 yen.
is reduced, and this difference of 5,400 yen is stored in the sales totalizer 42. Thereafter, the deposit/total key 14 is operated. Then, the total amount due to cash transactions is r5,400 yen.''
is printed, and the point "54" is calculated from this total amount r5400J yen and the standard amount rloOJ yen, and this point "54" is added to the point "50" in the cumulative point memory 43 to make a new cumulative point r10.
4J is calculated. And this new cumulative points rl
04J is printed on the receipt, and a receipt as shown in FIG. 7 is issued. Also, this new cumulative point rl
04J is written in area M2 of card 8, and card 8 is ejected.

The cashier then hands the receipt and card 8 to the customer in exchange for the payment of r5,400J yen.

In this embodiment, points calculated according to the total amount of sales can be automatically accumulated on the memory card 8, and discounts can be given as appropriate according to the accumulated points on the memory card 8. , the customer is given the same benefits as with a service ticket. In this case, the customer only has to manage one memory card issued by the sender, so it is less complicated and easier to manage than when managing service tickets, and there is no risk of losing them. It becomes less. Therefore, more detailed services can be provided.

In addition, by simply entering the discount amount and operating the discount key 16, the discount is automatically processed according to the accumulated points on the memory card 8, and the discount is automatically processed according to the sales amount after the discount. Since the new accumulated points updated by the cashier are also automatically written to the memory card 8, the burden on the cashier can be significantly reduced compared to the case where service tickets are issued, and processing efficiency can also be improved.

In addition, in the above embodiment, a case was shown in which a discount amount is input as discount data, but discount points are input, the discount points are converted to a discount amount, and the discount is processed from the total sales amount. Good too. Furthermore, it goes without saying that the memory card 8 may be not only a magnetic card but also an IC card or the like. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, points calculated for the total sales amount can be accumulated and recorded on a memory card, and discounts can be easily processed according to the accumulated points of this memory card. It is possible to provide an electronic cash register that can further improve serviceability and reduce the burden on the cashier.
