BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sales data processing device capable of processing payment for sales products through credit transactions.

0002

[Prior Art] A conventional product sales data processing device of this type connects each credit company's host computer online, and also uses a card reader that can read card information of credit cards issued by each credit company. and a slip printer for printing credit slips. Further, the keyboard is provided with keys for inputting product sales data, a closing key for instructing closing of one transaction, etc., and is also provided with keys for inputting credit payment amount, payment method, etc.

[0003] When product sales data such as the number of products sold and the sales amount are input by key operations on the keyboard, the sales are registered in the sales data registration memory and the sales amount is stored in the total amount memory for each transaction. Store the cumulative total. When the closing key is operated to instruct payment by credit card transaction for the total amount in the total amount memory, the card reader reads card information such as the card issuing company code and membership number recorded on the credit card. After that, when the credit card payment amount and payment method are entered from the keyboard, the entered card information, payment amount, and payment method information is sent to the host computer of the relevant credit company to check the validity of the credit transaction (credit card payment method). Inquire whether the card is valid, whether the member has not yet exceeded the unpaid limit, whether the payment amount is within the single use limit, etc.) As a result, when the validity of the transaction is approved, the slip printer is driven and controlled to print out a credit slip.

[0004] By the way, some credit card customers have contracts with multiple credit companies and pay for one purchase through credit transactions with two or more companies. processed transactions separately for each credit company. For example, if a customer who purchases product a and product b offers a credit transaction with two credit companies A and B, the store will make the payment for product a a credit transaction with credit company A, and the store will pay for product b. Payment is made as a credit transaction with credit company B. and,
First, with a credit card from credit company A attached to a card reader, product a is registered for sale, and then the credit transaction closing key is operated. Then, product a
The payment is processed as a credit transaction with credit company A, and a credit slip is issued. Next, with the credit card of credit company B attached to the card reader, after registering product b for sale, the user operates the credit transaction closing key. Then, the price for product B will be processed as a credit transaction with credit company B.
A credit slip will be issued.

[0005]

[Problems to be Solved by the Invention] As described above, in the conventional product sales data processing device of this kind, when one customer pays for a product through credit transactions with multiple credit companies, Because transactions had to be processed separately, product registration operations were required for each transaction, resulting in poor work efficiency.

[0006] Accordingly, the present invention makes it possible to perform the product registration operations for the transactions at once when the payment for one transaction is made in credit transactions with multiple credit companies, thereby making it possible to efficiently process the credit transaction registration operations. The present invention aims to provide a product sales data processing device.

[0007]

[Means for Solving the Problems] The present invention provides a memory for registering sales data that is connected online to host computers of a plurality of credit card companies, and when product sales data such as the number of products sold and sales amount is input. At the same time, the sales amount is cumulatively stored in the total amount memory for each transaction, and when payment by credit transaction is instructed for the total amount in the total amount memory due to the closing operation of one transaction, the corresponding credit company In the product sales data processing device that inquires of the host computer about the validity of the credit transaction and prints out the credit slip when the validity is approved, input the payment amount by credit within the range of the total amount in the total amount memory. payment amount input means; 1.
A payment amount processing means that processes a credit transaction for the payment amount when the payment amount is input by the payment amount input means in a state where payment by credit transaction is instructed by the transaction closing operation, and the credit transaction is processed by the processing means. a reduction means for subtracting the paid amount from the total amount in the total amount memory; a remaining amount determining means for determining whether there is a remaining amount in the total amount memory after the payment amount has been reduced by the reduction means;
If this determination means determines that there is a remaining amount, the payment amount input means is allowed to input a payment amount within the range below the remaining amount, and one transaction is continued; if it is determined that there is no remaining amount, one transaction is terminated. and control means.

[0008]

[Operation] With the product sales data processing device configured as described above, when product sales data such as the number of products sold and the sales amount is input, the sales are registered in the sales data registration memory and the sales amount is recorded for each transaction. The total amount is accumulated and stored in the memory. Then, by instructing payment by credit transaction by closing one transaction, and at this time, inputting the payment amount by credit within the range of the total amount in the total amount memory using the payment amount input means, the host computer of the corresponding credit card company The validity of the credit transaction for the payment amount is queried, and if the validity is approved, a credit slip is printed out.

Next, the amount to be paid is subtracted from the total amount in the total amount memory. As a result, if there is a remaining amount in the totalizer memory, input of the payment amount by the payment amount input means is permitted within the range below the remaining amount. In this state, if a payment amount that is less than or equal to the remaining amount is entered, the host computer of the relevant credit company is queried as to the validity of the credit transaction for the payment amount, and if the validity is approved, a credit slip is generated. Printed out. In this way, one transaction ends when the remaining amount in the total amount memory is exhausted.

A keyboard 12 is provided at the front of the top surface for inputting product sales data, etc., and a display 13 is provided at the center of the top surface for displaying the sales amount, total amount, etc. A mode switch 21 is also provided on the front. Furthermore, a card reader 14 for reading card information such as the card issuer code and membership number recorded on the credit card is attached to one side, and a drawer 15 for storing cash etc. is attached to the bottom side. installed. A printer for printing receipts and journals is built into the housing of the electronic cash register 11, and a receipt printed by this printer is issued from a receipt issuing port 16 formed on the back side of the display 13. It is now possible to do so.

Reference numeral 17 in the figure is a slip printer for printing credit slips, and the printed credit slips are issued from a slip issuing port 18 formed at the top of the housing. The electronic cash register 11 and the slip printer 17 are electrically connected via a signal cable 19. In addition, the above electronic cash register 1
1 is connected to a host computer of each credit company via a transmission line 20 such as a telephone line.

The mode switch 21 is used to turn on the power,
It is a control switch for controlling off and selecting various business modes such as "registration", "settlement" and "setting". This is a business that prints information on journals and issues receipts, and when payment for products sold through credit transactions is declared, a credit inquiry is made to the host computer of the relevant credit company, and when a sales approval response is received, a slip printer is sent. From 17 onwards, credit slips will be printed and issued.

As shown in FIG. 3, the keyboard 12 includes numeric keys 31 for inputting numerical data such as the number of products sold and prices, and a plurality of preset department codes for classifying each product. A department key 32, a multiplication key 33 used to input a multiplier, a subtotal key 34 that instructs to output the subtotal amount, a credit card key 35 that instructs the closing of product registration when paying by credit, and a credit key 35 when paying by cash. a current key 36 for instructing the closing of product registration;
In addition to normal keys such as the clear key 37 used to clear errors and clear numbers, the payment method key 38 is used to enter payment methods such as "split", "lump sum", "combined with bonus", etc., and the credit payment amount is entered. A credit transaction key for a payment amount key 39 is provided.

FIG. 2 is a block diagram showing the circuit configuration of the electronic cash register 11. In the figure, reference numeral 41 denotes a CPU (central processing unit) 41 constituting the main body of the control unit, which performs various data processing based on input data from the keyboard 12, etc., and is connected to a ROM ( read-only memory) 43 and RAM (
random access memory) 44. Also, a clock circuit 45 that measures the current date and time, an I/O port 46 that receives a signal from the mode switch 21 and outputs an open drive signal to the drawer 15, and a A communication interface 48 controls data transmission and reception between the host computers 47a, 47b, . Display controller 50 that displays characters, etc. corresponding to
, a printer controller 52 that drives and controls a printer 51 that prints on receipts and journals, a card reader interface 53 that takes in card information read by the card reader 14, and a printer 17 connected to the slip printer 17 via the signal cable 19. Each section, such as a printer interface 54 that controls data transmission and reception, is connected to the CPU 41 via the bus line 42.

The ROM 43 stores in advance fixed data such as program data for the CPU 41 to control each section and character generator data for display characters or printed characters.

The total amount of RAM43, as shown in FIG. 4, is a memory for sales data registration for sales registration processing, and the total amount for the sales amount of registered products for each transaction. A memory 62, a payment amount memory 63 that stores the credit payment amount, a card information buffer 64 that temporarily stores the credit card information read by the card reader 14, and is set to "0" when the credit card is attached to the card reader 14. Various memory areas such as a flag memory 65 for the card flag F are reserved.

[0018] The CPU 41 receives numerical data input using the numeric keys 31 of the keyboard 12 while the "registration" mode is selected using the mode switch 21.
Next, when the department code is input using the department key 32,
Since the products belonging to the department code have been registered for sale with the sales amount of the numerical data, the program registers the product sales data in the sales data registration memory 61 and cumulatively processes the sales amount in the total amount memory 62. It is set.

Furthermore, the CPU 41 is programmed to execute the process shown in FIG. 5 in response to an interrupt from a one-second timer in the "registration" mode, for example. That is, when an interruption occurs, it is checked whether a credit card is inserted into the card reader 14 or not. Then, if a credit card is attached, the card flag F of the flag memory 65 is set, and if a credit card is not attached, the flag F is reset,
This interrupt processing ends.

Further, the CPU 41 is programmed to execute the process shown in FIG. 6 when the current total key 36 of the keyboard 12 is input in the "registration" mode. That is, the value stored in the total amount memory 62 is “
After confirming that the payment amount is larger than "0" and that the value stored in the payment amount memory 63 is "0", a normal cash transaction is processed for the value stored in the total amount memory 62. Thereafter, the total amount memory 62 is Clear it to "0" and end this process.

[0021] Note that the stored value of the total amount memory 62 is "0".
or the value stored in the payment amount memory 63 is “0”
If a larger value is detected, this current key input is treated as an error.

The CPU 41 is programmed to execute the process shown in FIG. 7 when the credit card key 35 of the keyboard 12 is input in the "registration" mode. That is, first, the card flag F in the flag memory 65 is checked, and if the flag F has been reset, it waits until it is set. When the flag F is set, since a credit card is attached to the card reader 14, the card information such as the credit company code and membership number recorded on the credit card is read and stored in the card information buffer 64. . Next, the system waits for the credit payment amount or credit payment method to be input using the payment amount key 39 or payment method key 38 of the keyboard 12.

[0023] Here, when numerical data is input to the number key 31 and then the payment amount key 39 is operated, the credit payment amount is input, so the credit payment amount and the value stored in the total amount memory 62 are Compare with. If the payment amount is less than the value stored in the total amount memory 62, the key-input credit payment amount is validated and written into the payment amount memory 63. (Payment amount input means)

[0024] Thereafter, the system waits for the credit payment method to be input. However, if the credit payment amount is re-entered within a range less than the value stored in the total amount memory 62, the re-input payment amount is made valid and written into the payment amount memory 63.

When a credit payment method is input using the payment method key 38, the value stored in the payment amount memory 63 is checked. Here, if the memory value is "0", the credit payment amount was not keyed in, but the payment method was keyed in, so
It is determined that a credit transaction has been instructed for the amount stored in the total amount memory 62, and the total amount memory 62
The stored value is written into the payment amount memory 63. Payment amount memory 6
If the stored value of 3 is greater than "0", it is determined that a credit transaction has been instructed for that payment amount. A normal credit transaction is then processed for the value stored in the payment amount memory 63. After the credit transaction, the value stored in the payment amount memory 63 is subtracted from the value stored in the total amount memory 62, and the result is written in the total amount memory 62. (Amount reduction means) Also, the payment amount memory 63 is cleared to "0". next,
The value stored in the total amount memory 62 is checked to determine whether there is any remaining amount in the total amount memory. (Remaining amount determination means)

Here, if the stored value in the memory 62 is greater than "0", it is determined whether there is a remaining amount of the total amount, and the system waits for the closing key of the credit key 35 or the cash key 36 to be input. If the trust key is input, the trust key process shown in FIG. 7 is executed again. On the other hand, when the current total key 36 is input, the current total key processing shown in FIG. 6 is executed. On the other hand, if the stored value of the total amount memory 62 is "0", it is determined that there is no remaining amount of the total amount, and this process is ended. (Transaction control means)

In this embodiment configured as described above, when one customer registers the sale of a product by operating the numeric key 31, department key 32, etc. of the keyboard 12, the product sales data is Sales are registered in the sales data registration memory 61, and the sales amount of the products purchased by the customer is accumulated and stored in the total amount memory 62. When the customer completes the sales registration operation for all the products purchased, the customer operates the closing key according to the customer's payment method.

Here, if the customer proposes payment in cash, the customer operates the cash key 36 as a closing key. Then, the printer 51 prints a receipt with the total amount stored in the total amount memory 62 as the cash payment amount, and the receipt is issued from the receipt issuing port 16. Also drawer 1
5 is opened and cash can be exchanged. But 1
The transaction ends.

On the other hand, if the customer proposes payment by credit card transaction, the credit card key 35 is operated as a closing key. Further, the customer inserts the credit card received from the customer into the card reader 14, and inputs the credit payment amount and payment method using the payment amount key 39 and payment method key 38.

[0030] Here, if the customer wishes to pay the entire amount of the total amount in a credit transaction with one credit card company, the key input of the payment amount key 39 is omitted, and the key input of the corresponding payment method key 38 is performed. Then, the value stored in the total amount memory 62 is set as the credit payment amount in the host computer of the credit company that issued the credit card, and the validity of the credit transaction is queried. As a result, if the validity of the transaction is approved, the document printer 1
7 is driven and a credit slip is printed out. One transaction is thus completed. Note that the payment amount, ie, the total amount, may be entered using the payment amount key 39.

[0031] On the other hand, if the customer is credit card company 1
When paying part of the total amount in a credit transaction with a company, the user inputs the amount to be paid using the payment amount key 39, and then inputs the corresponding payment method key 38. Then, the validity of the credit transaction for the credit payment amount keyed into the host computer of the credit company that issued the credit card is queried. As a result, when the validity of the transaction is approved, the slip printer 17 is activated and a credit slip is printed out. At this time,
The total amount memory 62 stores the amount obtained by subtracting the credit payment amount from the total amount. Here, when the current total key 36 is inputted, a receipt is printed by the printer 51 with the amount stored in the total amount memory 62 as the cash payment amount, and is issued from the receipt issuing port 16. Also drawer 1
5 is opened and cash can be exchanged. But 1
The transaction ends.

[0032] On the other hand, when a customer pays the total amount separately in a credit transaction with two credit card companies, first insert the credit card of the first credit card company into the card reader 14, and then The amount and payment method to be paid in a credit transaction with the company are entered using the payment amount key 39 and payment method key 38. Then, the validity of the credit transaction for the credit payment amount keyed into the host computer of the first credit company is queried. As a result, when the validity of the transaction is approved, the slip printer 17 is activated and a credit slip is printed out. At this time, the total amount memory 62 stores an amount obtained by subtracting the first company's credit payment amount from the total amount. Next, from the card reader 14
After removing the company credit card, Shinkei key 36
At the same time, the second company's credit card is inserted into the card reader 14. Next, the amount and payment method to be paid in the credit transaction with the second credit company are entered using the payment amount key 39 and payment method key 38. Note that the key input of the credit payment amount may be omitted. Then, the host computer of the second credit company is inquired about the validity of the credit transaction for the credit payment amount, that is, the amount obtained by subtracting the first company's credit payment amount from the customer's total amount. As a result, when the validity of the transaction is approved, the slip printer 17 is activated and a credit slip is printed out. At this time, the value stored in the total amount memory 62 becomes "0" and one transaction is completed.

[0033] According to this embodiment, when a customer pays the total amount separately in a credit transaction with two credit companies, after the customer registers the sale of the product he/she is purchasing, This can be done by sequentially entering the credit payment amount and payment method for each company. This holds true even if the number of credit card companies used by one customer increases. Therefore, compared to the conventional system in which transactions are separated for each credit company and product registration operations are required for each transaction, product registration operations can be performed all at once, so credit transaction registration operations can be performed efficiently.

[0034] In the above embodiment, the host computer of each credit card company is connected to a single electronic cash register 11 via the communication interface 48, but it is possible to connect multiple electronic cash registers and centrally manage them. The present invention can also be applied to a POS (point of sale) system in which a controller is connected in-line and a host computer of each credit company is connected to the controller. In this case, it is also possible for the controller to check the credibility of credit transactions without inquiring the host computer of the credit company. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[0035]

[Effects of the Invention] As detailed above, according to the present invention, when the price of one transaction is paid in credit transactions with multiple credit companies, the product registration operation for those transactions can be performed at once, and the credit card It is possible to provide a product sales data processing device that can efficiently process transaction registration tasks.
