Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register used in stores that uses receipts as discount coupons.

[Prior Art] For example, Japanese Patent Application Laid-Open No. 2-100199 discloses that each time a transaction is closed, a discount amount is automatically calculated according to the total amount of the transaction, and the discount amount is converted into a bar code. An electronic cash register has been disclosed which has a function of printing out a receipt from the cash register and a function of having a barcode reader and determining a discount amount from the barcode read by the barcode reader and processing the discount. By using such an electronic cash register, issued receipts can be used again as discount coupons, which has the advantage of increasing customer retention.

However, if we set an expiration date on this type of discount coupon,
The cashier needs to determine whether the discount voucher is within its validity period based on the date of issue of the receipt.

Furthermore, if a similar discount coupon had been issued at another store, the cashier had to judge from the logo on the receipt, etc. whether the discount coupon could be used at the store.

[Problems to be Solved by the Invention] As mentioned above, in conventional electronic cash registers of this type, discount processing is executed when the barcode of the discount coupon printed on the receipt is read with a barcode reader. , the validity of the discount coupon had to be determined by the cashier each time. Therefore, the judgment work becomes a burden on the cashier, and an invalid discount ticket may be processed for discount due to a judgment error.

Therefore, the present invention aims to provide an electronic cash register that can reduce the burden on the cashier by automating the determination of the validity of discount coupons, and can also reliably prevent the problem of discounts being given with invalid discount coupons. It is.

[Means for Solving the Problems] The present invention accumulates sales data of registered products in a memory each time a sales product is registered, and registers the sales data for each transaction each time a closing operation is performed. In an electronic cash register that issues a receipt on which detailed data and total data of products purchased are printed, a receipt code is edited from data regarding the discount generated by the transaction and data regarding the validity of the receipt in response to a closing operation. a code editing means, a receipt code printing means for printing the receipt code edited by the editing means on the receipt, a receipt code reading means for reading the receipt code printed on the receipt by the printing means;
a validity determining means for determining the validity of a receipt on which a receipt code is printed when a receipt code is read by a receipt code reading means before a closing operation is performed, and a case where the receipt is determined to be valid by the determining means; The apparatus is equipped with discount processing means for discounting the transaction based on discount data in the read receipt code.

[Function] If the electronic cash register has this configuration,
When a sales product is registered and a post-closing operation is performed, a receipt code is edited from the total data of the transaction and data regarding the validity of the receipt, and the receipt code is printed and issued on the receipt for the transaction. . The receipt issued in this way can be used as a discount coupon for the next purchase.

In this case, when the receipt code reading means reads the cash register code before the closing operation is performed, the validity of the receipt is determined from the validity data in the receipt code. When it is determined that the discount ticket is a valid receipt, the transaction is discounted based on the total data in the read receipt code.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of a receipt l issued from the electronic cash register of this embodiment.

As shown in the figure, receipt 1 includes detailed data 2 of the product registered for sale, total data 3, purchase date 4, and purchase time 5.
, in addition to receipt number 6, the date of purchase.

A receipt code barcode 7 consisting of a purchasing store code, a receipt number, a purchase amount, and a check digit (CD) of the purchase amount is printed.

8 in the figure is a logo mark of a store name, etc.

FIG. 2 is a block diagram of an electronic cash register, in which a CPU (central processing unit) 11 constitutes the main body of the control unit.
ROM 13 and RAM 14 via the pass line 12.
a storage section, and a clock circuit 15 for measuring date and time.
A keyboard that controls an I10 boat 17 into which a signal is input from a mode switch 16 for switching the business mode, and a keyboard 18 provided with a product registration key, a subtotal key, a closing key, etc. A controller 19, a display controller 21 that controls a display 20 that electronically displays the product name, price, total amount, etc. of products registered for sale, a printer controller 23 that controls a printer 22 that prints on receipts, journals, etc., and a bar code. Each part of a scanner controller 25 that controls a barcode scanner 24 as a receipt code reading means that scans and reads the receipt code is connected.

The ROM 13 stores fixed data such as program data and a numeric code/barcode conversion table.

On the other hand, as shown in FIG. 3, the RAM 14 includes, in addition to the sales registration memory 31, a date memory 32 in which the current date clocked by the clock circuit 15 is stored, and store information set in advance. a store code memory 33 in which the code is stored;
Receipt number counter 34 for counting a series of receipt numbers 1 Total amount memory 3 for storing the total amount of the transaction
5. Discount management table 36 in which the expiration date of the receipt used as a discount ticket, the discount target store code and the discount rate for the previous purchase amount are preset, and the receipt code printed on the receipt used as a discount ticket is saved. Various memories such as a used receipt code file 37 are formed.

The CPU II is program-controlled to execute the process shown in FIG. 4 when one transaction is started with the "registration" mode selected by the mode switch 16. First, when a bar code (product code) attached to a product is scanned by the scanner 24 or a product registration key on the keyboard 18 is operated to register the product for sale in the transaction, product registration processing is executed.

That is, the sales data of the registered product is accumulated in the sales registration memory 31. Further, the price of each registered product is added up in a total amount memory 35. Furthermore, the product name and price of the registered product are displayed on the display 20, and the printer 22 is driven to print them out on a receipt and a journal.

Next, when the subtotal key on the keyboard 18 is operated, subtotal output processing is executed. That is, total amount memory 3
Display unit 2 displays the amount data stored in 5 as a subtotal.
0 and drives the printer 22 to print on the receipt and journal.

Next, when the closing key of the keyboard 18 is operated before the bar code is scanned by the scanner 24, the closing process is executed. That is, the amount data in the total amount memory 35 is set as the total amount, the amount of change is obtained by subtracting the total amount from the deposited amount, and the amount of change is displayed on the display 20. The printer 22 is also driven to print out the total amount, deposited amount, and change amount on a receipt and journal. Furthermore, a receipt number counter 34
is counted up, and the count value is printed out as a receipt number on the receipt and journal together with the time data (purchase time) clocked by the clock circuit 15. Next, a receipt code is edited from the contents of the date memory 32, store code memory 33, receipt number counter 34, and total amount memory 35 (receipt code editing means). Here, the contents of the total amount memory 35 are the total data of the transaction, and the date memory 32 and store code memory 33
The content of is data regarding the validity of the receipt. Next, the edited receipt code is converted into a barcode using the numeric code/barcode conversion table in the ROM 13. Then, the printer 22 is driven to print out the barcode of the receipt code on the receipt (receipt code printing means). Thereafter, the above-mentioned receipt issuance process is performed, and the registration work for one transaction is completed. In the above-mentioned receipt issuing process, a logo mark and date data (purchase date) clocked by the clock circuit 15 are printed on the receipt of the next transaction.

On the other hand, if a barcode is scanned by the scanner 24 before the close key of the keyboard 18 is operated, if the barcode is a barcode attached to a product, the process returns to the product registration process.

On the other hand, in the case of a bar code printed on a receipt, that is, a receipt code, the discount process shown in FIG. 5 is executed. In other words, the receipt code includes the date of purchase and store code as shown in Figure 1.

Since it consists of a receipt number, a purchase amount, and a check digit for the purchase amount, this is analyzed, and four validity checks are performed based on the analysis results. First, it is determined whether the check digits are correct. If they match, proceed to the next check, but if they do not match, an error occurs.

In the next check, it is determined whether the receipt code is unused. That is, the used receipt code file 37 is searched to determine whether or not the same code as the concerned receipt code is stored.

If the file has not been saved, it will proceed to the next check, but if it has been saved, an error will occur. In the next check, it is determined whether the receipt on which the receipt code is printed is valid as a discount ticket for a limited time. That is, the expiration date preset in the expiration date area of the discount management table 36 is compared with the purchase date in the receipt code. If the purchase date is on or after the expiration date, the item is valid for a limited period of time, so proceed to the next check; however, if the purchase amount is before the expiration date, the item has expired and an error occurs. In the next check, it is determined whether the receipt on which the receipt code is printed is a receipt issued by a store eligible for discount. That is, the store code preset in the discount target store code area of the discount management table 36 is compared with the store code in the receipt code. If a store code that matches the store code in the receipt code is preset, it is determined that the receipt code is valid, but if it is not preset, an error occurs. (Effectiveness Judgment Means) If effectiveness is judged by the above four checks, the discount management table 36
Search the previous purchase amount area and check the area that includes the purchase amount in the receipt food. Then, the discount rate corresponding to that area is read out. In other words, the purchase amount in the receipt code is data regarding discounts. Next, a discount calculation is performed on the amount data in the total amount memory 35 using the above discount rate, and the printer 22 is driven to print out the discount amount on a receipt and a journal. In addition, the amount data after discount is stored again in the total amount memory 35, and the display 20
to be displayed. Thereafter, the read receipt code is stored in the empty area of the used receipt code file 37, and this discount processing is completed. (Discount processing means) After that,
When the closing key on the keyboard 18 is operated, the above-described closing process and subsequent processes are executed, and the registration work for one transaction is completed.

In this embodiment configured in this way, when the customer registers the purchased product and closes the registration,
In addition to detailed data 2 and total data 3 of registered products, a receipt code consisting of the purchase date, purchase store code, receipt number, purchase amount, and check digit of the purchase amount is converted into a barcode 7, printed on the receipt L, and issued. be done. The receipt 1 thus issued is used as a discount ticket for the next shopping trip. That is, when a customer pays at the cash register, he/she presents the receipt 1 from the previous shopping to the cashier. After outputting the customer's subtotal, the cashier scans the barcode 7 printed on the receipt 1 using the scanner 24.
Read with Then, check whether the digits of the purchase amount are correct, whether the receipt is an unused discount coupon, or whether it was issued within the expiry date.
Each receipt is automatically checked to see if it was issued by a store eligible for the discount. If all conditions are satisfied, the validity of the receipt is determined, and a discount is applied to the current total amount based on the purchase amount in the receipt code.

As described above, according to this embodiment, in addition to data related to discounts, that is, the purchase amount, data related to the effectiveness of discounts, such as date of purchase, store code, check digit, etc., are converted into barcodes and issued as receipts. It is printed on. By reading the barcode printed on the issued receipt with a scanner 24, the validity of the discount ticket is automatically determined, and the discount is processed only when it is determined that the ticket is valid.

Therefore, the cashier does not need to confirm the validity of the discount ticket, which reduces the burden on the cashier and reliably prevents the problem of discount processing being performed with an invalid discount ticket.

In the above embodiment, the receipt code is converted to a bar code, but it is also possible to print the receipt code as a numeric code and read the numeric code using an optical character reader (OCR). Further, in the above embodiment, the purchase amount is shown as the data regarding the discount, but the present invention is not limited to this. For example, the barcode data may include a discount rate calculated based on the purchase amount.

[Effects of the Invention] As detailed above, according to the present invention, the burden on the cashier can be reduced by automating the determination of the validity of discount coupons, and the problem of discounts being given with invalid discount coupons can be reliably prevented. We can provide electronic cash registers that can
