Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register capable of automatically calculating privilege information based on a total price of products registered for sale in one transaction and giving the privilege information to a customer.

[0002]

2. Description of the Related Art As a conventional electronic cash register of this type, when a closing key is used to instruct registration closing of one transaction, the total amount of goods registered for sale in the transaction is converted into points, and the points are converted into points. In some cases, the receipt was printed on the receipt together with the product sales detail information and total information of the transaction and issued to the customer.

In a store using such an electronic cash register, when the value obtained by adding the points of the receipt presented by the customer reaches a predetermined value, a privilege such as a discount or a gift presentation is given. , It is possible to establish the customer.

[0004]

However, in this case, since the customer collects several receipts issued each time he / she purchases before using them, it is troublesome to manage the receipts collectively. Yes it was not practical.

Therefore, conventionally, a magnetic card reader / writer is attached to an electronic cash register, a magnetic card for accumulating points is issued to a customer, and the points calculated by each shopping are accumulated in the magnetic card. there were. In this case, the customer is required to carry one magnetic card at all times and present it to the store every time he / she makes a purchase, so that the effect of the fixation is great.

However, for the store side, an electronic cash register to which a magnetic card reader / writer is attached must be introduced, and a magnetic card must be issued to each customer, resulting in a significant increase in equipment costs. there were.

Therefore, the present invention intends to provide an electronic cash register capable of accumulating and processing privilege information calculated by each shopping without burdening the customer and without increasing the facility cost on the store side. It is what

[0008]

According to the present invention, when a registration closing instruction for one transaction is instructed by a closing key, a receipt is printed from a printer on which sales detail information and total information of products registered for sale in the transaction are printed. In addition, in the electronic cash register that automatically calculates the privilege information for the total amount of money, privilege information input means for inputting privilege information,
The privilege information storage unit stores the privilege information when the privilege information is input by the input unit before the key input of the closing key, the privilege information newly calculated according to the key input of the closing key, and the storage unit. It is provided with a privilege information accumulating means for adding the stored privilege information, and a privilege ticket issuing means for issuing from the printer a privilege ticket on which the privilege information accumulated value obtained by the accumulating means is printed.

[0009]

According to the present invention having such a structure, if one customer registers the sale of the purchased product and then inputs the closing key to instruct the closing of the sale, the sales of the registered sale of the product will be performed. The printer issues a receipt on which the detailed information and the total information are printed, the privilege information for the total amount is automatically calculated, and the privilege ticket on which the privilege information is printed is issued from the printer.

Then, the customer presents the privilege ticket to the store at the next shopping. On the other hand, the store side inputs the privilege information of the privilege ticket by the privilege information input means before instructing the registration closing of the product purchased by the customer with the closing key. Then, the input privilege information is stored in the privilege information storage means. After that, when the closing key is keyed in, the privilege information for the total amount of shopping for this time is calculated, and the privilege information for the privilege ticket issued by the previous shopping is stored in the storage means. Is added to. Then, the added value of the privilege information after addition is newly printed and issued as a privilege ticket.

Therefore, the customer always carries one privilege ticket, and the privilege can be obtained only by presenting the privilege ticket to the shop side every time shopping is performed, so that the customer can be fixed. On the other hand, the store side does not need to make any capital investment other than changing the program, and can be implemented at low cost.

A display 15 for a customer is attached to the upper surface of the housing 10, and a drawer 16 for storing cash or the like is provided on the lower surface so as to be openable and closable. Further, a bar code scanner 17 for reading a bar code printed or attached to a product by a label is connected to an electronic cash register via a cable 18.

The mode switch 11 is for turning on the power,
Control OFF, "Register", "Check", "Settlement"
It selects various business modes such as "setting" and informs the central processing unit of the execution thereof, which can be switched with a key.

As shown in FIG. 5, the keyboard 12 includes a numeral key 12a for inputting numerical data, a plurality of department keys 12b preset with department codes for classifying each product, and a subtotal key 12c. Various function keys such as a ticket key 12d, a deposit / cash total key 12e, a clear key 12f, and a cancel key 12g are provided.

Here, the ticket key 12d is a closing key that is input when paying all or part of the product price with the accumulated bonus points of the privilege ticket 2, and the deposit / cash total key 12e is the total price of the product. Alternatively, it is a closing key that is input when paying a part in cash.

FIG. 4 is a block diagram showing a control circuit of the electronic cash register, 21 is a CPU (central processing unit) which constitutes the main body of the control unit, and 22 is program data and code for the CPU 21 to control each unit. / ROM with pre-stored barcode conversion table etc.
(Only memory), 23 is a RAM in which various memory areas for storing data processed by the CPU 21 are formed.
(Random access memory), which are connected to each other by a bus line 24.

A clock circuit 2 for measuring the date and time
5, a keyboard controller 26 that controls the keyboard 12, a display controller 27 that controls the respective display devices 14 and 15, a printer controller 29 that controls a printer 28 that issues and prints the receipt 1 and the privilege ticket 2, and the bar code. Scanner interface 3 that captures barcode data read by the scanner 17
0, a communication interface 31 for controlling data transmission / reception to / from a host device (not shown) externally connected via a communication line, and a signal from the mode switch 11 are input and the drawer 16 is opened. An I / O port 32 that outputs an opening command signal to the drawer opening device 16a is connected to the CPU 21 via the bus line 24.

As shown in FIG. 6, the RAM 23 has a sales registration memory 23a for storing sales data of products registered for sale, and a work memory having a plurality of work areas A to H used by the CPU 21 for calculation. 23b, a flag memory 23c that stores a registration flag that is set during product registration for one transaction and a shortage flag that is set when the amount of payment is insufficient, and various data necessary for calculating privilege points. A point management table 23d and the like set in advance are formed.

Here, in the point management table 23d, "issue unit", which is a unit of the amount of money to which the privilege points are given, "issue point" which is the number of privilege points given in this "issue unit", and a privilege "Unit of use" which is the unit of the number of points when using points for payment, "Point amount" which is the amount of 1 point used for payment in this "unit of use", the number of days until the expiration date of the privilege ticket Data is set for each item of "a certain number of days until expiration" and "a point number of less than" which is a point number given to the amount of money less than the "issue unit".

Therefore, the CPU 21 is programmed so as to execute the control shown in FIG. 7 when the bar code scanner 17 performs a bar code reading operation, that is, scanning.

That is, when the bar code of the product code is read by the bar code scanner 17 while the "registration" mode is selected by the mode switch 11, the register flag in the flag memory 23c is checked.
When the registration flag is reset, the first product registration in one transaction is performed, so the registration flag is set and the work areas A to H of the work memory 23b are cleared. If the in-registration flag is set, the product for one transaction is being registered and the second and subsequent products have been registered, so the above processing is not performed.

Next, an inquiry message for the read product code is created, and an inquiry about product information is made to the host device via the communication interface 31. As a result, the host device responds with product information such as the product name and unit price corresponding to the product code in the inquiry message. If this response is received, the unit price is multiplied by the sales point to calculate the sales amount, Acquires product sales data such as product code, number of sales, and sales amount.

Then, the product sales data is stored in the sales registration memory 23a. In addition, the above sales amount is added to the contents of work area A, and the addition result is work area A.
Store again. Therefore, the work area A stores the total price of the registered products in one transaction. Further, the product sales detailed information such as the product name and the sales amount is displayed on each of the display devices 14, 1.
5, the printer 28 is drive-controlled to print out on the receipt 1, and this processing is ended. In addition,
If the host device does not normally respond to the product information, a product code that has not been set in the host device has been read, and the barcode input is regarded as an error.

On the other hand, the mode switch 11 causes "registration".
Bar code scanner 17 with mode selected
Even when the bar code 2f of the privilege code printed on the privilege ticket 2 is read by, the registration flag is also checked. When the registration flag is set, the validity period 4a and the store code 4b of the privilege code 2f are checked to determine the validity of the privilege ticket.

Here, if the store code is valid and valid, the privilege ticket is determined to be valid. Then, the cumulative points 4c of the privilege code 2f are added to the contents of the work area B, the addition result is stored again in the work area B, and this processing is ended. Therefore, the total points of the privilege ticket 2 are stored in the work area B. Here, the barcode scanner 17 constitutes a privilege information input means, and the work area B constitutes a privilege information storage means.

If the registration flag is reset, or if the validity ticket has expired or the privilege ticket is not valid, the bar code input is an error. Further, the CPU 21 is programmed to execute the control shown in FIG. 8 when the ticket key 12d of the keyboard 12 is pressed.

That is, when the ticket key 12d is key-inputted in the "registration" mode, it is judged whether or not the numeral data is inputted by the numeral key 12a, and if so, the numeral data is inputted. Is less than or equal to the content of work area B. When the numerical data is less than or equal to the contents of the work area B, the payment of points is instructed within the range of the accumulated points of the privilege ticket. Stored in work area C.

Next, the contents of the work area C are divided by the "unit of use" in the point management table 23d, the fractional part is rounded down, the result is multiplied by the "unit of use", and the "point amount of money" in the point management table 23d is multiplied. To calculate the amount paid by points. Then, the point payment amount is stored in the work area D.

Next, from the contents of the work area D, that is, the point payment amount, the contents of the work area A, that is, 1
The total amount of transactions (tax included amount) is subtracted, and the result is stored in the work area E. Here, when the content of the work area E is negative (negative), the payment amount is insufficient, so the shortage flag of the flag memory 23c is set, and the content of the work area E is displayed as the shortage amount. This is displayed on the containers 14 and 15 and the processing is terminated.

On the other hand, when the content of the work area E is zero or positive (plus), the amount of payment is sufficient, so the content of the work area E is used as the amount of change for each display unit 1.
4 and 15 are displayed. Further, the printer 28 is drive-controlled to print out the contents of the work areas D and E as receipt information on a receipt.

Next, the contents of work area A, that is, 1
If the total amount of transactions is divided by the "issue unit" in the point management table 23d, it is determined whether or not there is a number below the decimal point. And if there is no number below the decimal point,
The division result is multiplied by the “issue point” in the point management table 23d to obtain the special point this time. When there is a numerical value below the decimal point, the division result is multiplied by the “issue point” in the point management table 23d, and the “less than number of points” in the point management table 23d is added to obtain the present privilege point. Then, this privilege point this time is stored in the work area F.

Next, the contents of the work area F are added to the contents of the work area B, and the result, that is, the accumulated value of the previous point accumulated value and the present privilege point is stored in the work area G. Then, the contents of the work area G are set as the cumulative points 4c in the privilege code 2f, and the date obtained by adding the "expiration date" in the point management table 23d to the current date counted by the clock circuit 25 is the expiration date 4a. As a result, the privilege code 2f is created together with the preset store code 4b. (Means for accumulating privilege information)

Next, the printer 28 is drive-controlled to print the privilege ticket 2 after the receipt 1. In this case, the privilege code 2f is converted into a bar code by the code / bar code conversion table of the ROM 22 and printed. Further, the contents of the work area G as the bonus point cumulative value 2d, the work area B as the point information 2e,
Print the contents of C and F respectively. After that, the receipt 1 and the privilege ticket 2 are issued successively, the registering flag is reset, and this processing ends. (Bonus Ticket Issuing Means) Further, the CPU 21 is programmed to execute the control shown in FIG. 9 when the deposit / cash total key 12d of the keyboard 12 is pressed.

That is, when the deposit / cash total key 12d is keyed in the "registration" mode, the insufficient flag in the flag memory is first checked. Then, when this shortage flag is set, it is determined whether or not the numeric data is input by the numeric key 12a. If yes, the numeric data is equal to or greater than the contents of the work area E. Or not. And the numerical data is work area E
In the case of more than the contents of, since the payment in cash is instructed for the shortage of the payment, the numerical data, that is, the amount of cash to be paid for is stored in the work area H.

Next, the change amount is obtained by subtracting the content of the work area E, that is, the remaining payment amount from the content of the work area H, that is, the cash payment amount, and the change amount is stored in the work area E. Then, the contents of the work area E, that is, the change amount is displayed on each of the display devices 14 and 15. Further, the printer 28 is drive-controlled to print out the contents of the work areas H and E as payment information on the receipt 1.

Thereafter, the privilege points at this time are calculated and a privilege code is created in the same manner as in the case of the input processing of the ticket key 12d described above. Then, the privilege ticket 2 is printed after the receipt 1, and the receipt 1 and the privilege ticket 2 are issued from the receipt issuing port 13. Then, the in-registration flag and the shortage flag are reset, and this process ends.

On the other hand, during registration, the deposit / cash key 12e
When the key input is performed and the shortage flag is reset, it is determined whether or not the numeric data is input by the numeric key 12a. If yes, the numeric data is stored in the work area A. It is determined whether or not the content is greater than or equal to.
If the number data is more than the contents of work area A, the full payment of cash is instructed.
The number data, that is, the amount of cash used for payment is stored in the work area H.

After that, the change amount is obtained and displayed on the respective display units 14 and 15 in the same manner as in the case of the balance payment described above. Further, the printer 28 is drive-controlled to print out the payment information on the receipt 1. Furthermore, the privilege points for this time are calculated and a privilege code is created. Then, the privilege ticket 2 is printed after the receipt 1, and the receipt 1 and the privilege ticket 2 are issued from the receipt issuing port 13. After that, the registering flag is reset, and this process ends.

In a store using this embodiment having such a configuration, the keyboard 1 of the host device or the electronic cash register is previously set in the "setting" mode before the store is opened.
2 is used to set each data of the point management table 23d. Incidentally, in this embodiment, the “issue unit” is 10
0 yen, "issue point" 1 point, "unit of use" 10 points, "point amount" 1 yen, "expiration days" 30 days, "less than point" 1 point To do.

During business, the "registration" mode is set, and the bar code scanner 17 reads the product code to register the sales of the product purchased by the customer. Then, the total amount (including tax) of the products purchased by the customer is stored in work area A.

If the customer is a new customer, the payment for the merchandise in cash is accepted. Then, when payment is made in cash, after registering the payment amount, deposit /
Input the current total key 12e. Then, privilege points for the total amount are automatically calculated, and a privilege code including information on the privilege points and the expiration date is created. Then, the privilege ticket 2 in which the privilege code is bar-coded is printed, and is issued following the receipt 1 on which the detailed information of the purchased product and the payment information thereof are printed.

Thus, the customer who receives the privilege ticket 2 presents the privilege ticket 2 to the store when paying for the next shopping. On the other hand, upon receipt of the presentation of the privilege ticket, the store side operates the bar code scanner 17 to read the bar code 2f of the privilege code printed on the privilege ticket 2 before keying the registration closing key. Then, the cumulative points 4c of the privilege code 2f are stored in the work area B.

After that, when the customer pays only in cash and enters the deposit / cash total key 12e to declare the deadline for registration, privilege points for the total amount of shopping this time are automatically calculated, and This privilege point is added to the accumulated points up to the previous time in work area B.
Then, a privilege code is created based on the accumulated points obtained by adding the privilege points this time, a privilege ticket 2 is printed, and the ticket is issued subsequent to the receipt 1.

When the customer who presents the privilege ticket pays part or all of the price using the accumulated points up to the previous time, the store side sets the number of points used by the customer for payment and then the ticket key. Key in 12d. Then, the payment amount corresponding to the number of points used is automatically calculated, and the payment amount and the total amount are compared. When the payment amount is equal to or more than the total amount, the deviation is displayed as change. On the other hand, when the total amount exceeds the payment amount, the deviation is displayed on the display as a shortage amount, and the customer pays the shortage amount in cash.

Thus, even when the accumulated points up to the previous time are used for payment, the privilege points of this time are added to the accumulated points of which the payment is subtracted to calculate the accumulated points of this time, and the privilege ticket 2 is obtained. It will be printed and issued after receipt 1.

As described above, according to the present embodiment, the customer can carry the latest one of the privilege tickets issued each time he / she shop, and simply present it to the shop side at the appropriate time. The privilege ticket 2 can be easily managed because the privilege ticket 2 is received. Therefore, since the privilege is given to the customer without burdening the customer, it can be easily spread and the customer can be firmly established.

Moreover, since the printer 28 for printing the receipt prints and issues the privilege ticket information on the receipt paper, there is no need to issue a magnetic card to each customer, and in addition to changing the conventional program. There is no need for a special device such as a magnetic card reader and writer, and the facility cost for introducing this embodiment to a store side is low, and the profit can be greatly increased.

In the above embodiment, the privilege code 2f of the privilege ticket 2 is printed as a bar code, and the accumulated points up to the previous time are input by reading with the bar code scanner 18, but the privilege key 12a is used. The cumulative points 2d printed on 2 may be keyed in. Further, the receipt 1 and the privilege ticket 2 may be issued separately.

Further, in the above embodiment, the case where the privilege information is converted into points and accumulated is shown, but the amount of money as a privilege may be accumulated as it is. Of course, various modifications can be made without departing from the scope of the present invention.

[0053]

As described above in detail, according to the present invention, the privilege information calculated by each shopping is accumulated without burdening the customer and without increasing the facility cost of the store. An electronic cash register that can be processed can be provided.
