Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register, and more particularly to an electronic cash register in which payments can be made using a card.

Conventionally, electronic cash registers used, for example, in supermarkets,
There are known devices that are equipped with a card reader and allow payment by card. In such an electronic cash register, a card reading operation is performed at the beginning of a transaction, and after checking the read card data, details such as the price, quantity, department code, etc. of the sold merchandise are registered.

However, in the conventional method, before registering details, it is necessary to ask the customer whether to pay by cash or card.
Since it is impossible to change the payment method after registering the statement, there is an inconvenience in that the degree of freedom in operating the electronic cash register is restricted. This method has the disadvantage that it cannot be used in places where it is difficult to accept payment method inquiries in terms of business practices. Furthermore, there was also the inconvenience that it was not possible to select or change the payment method between cash and card depending on the accumulated amount at each point in time or the final total amount.

SUMMARY OF THE INVENTION In view of the problems with the conventional type described above, an object of the present invention is to provide an electronic cash register that allows commercial transactions using a card, and to perform a card reading operation at any time before the transaction is completed. Based on the concept of making it possible to use electronic cash registers, the system eliminates the need to inquire about payment methods from customers before registering their details, and allows them to select or change payment methods at any time, increasing the degree of freedom in operating electronic cash registers. There is a particular thing.

The present invention is an electronic cash register that enables a plurality of types of commercial transactions including those using cards, and includes a card reader that reads data recorded on the card, and a card reader that reads data recorded on the card. a first memory storing information read by the card reader; and alternatively at least information specifying a card transaction and information instructing to perform a closing operation process for another form of commercial transaction. an input means for inputting an input, a detection means for detecting when an input is made by the input means, and detecting which of these pieces of information the input is an input; If the first memory is set when the detection means detects that information specifying a transaction by card has been input, a closing operation for the card transaction is performed while the first memory is set. The present invention is characterized in that it is provided with a control means for displaying a card reading request if the card reading request is not made.

According to this, information specifying a transaction by card can be entered after the registration process and before the closing operation, so the card reading operation, that is, the selection of whether to pay by card or by cash, etc. can be completed. This can be done at any time before the transaction (before the end of the transaction). Therefore, the payment method can be freely selected or changed depending on the accumulated amount or total amount of the payment, and the customer is asked about the payment method before registering the details. Transactions are made without need.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 schematically shows a key arrangement on a keyboard KB of an electronic cash register (hereinafter referred to as ECR) according to an embodiment of the present invention. In the same figure, NK is a numeric key, 0 to 9 keys, 2
It has a 00 key for inputting consecutive zero digits and a clear key CL. DK is a department key, and five types of department codes from D1 to D5 can be entered.
The card sales key CK is a key to specify payment by card, the subtotal key STK is a key to press to obtain the subtotal, and the cash sales key CTK is a key to enter the deposit for cash sales and the total payment amount. This key is used when finding the . Further, the changeover switch SW is a switch that specifies the power on/off and operation mode of the ECR.

As shown in Figure 2, the ECR hardware includes a central processing unit CPU, a keyboard KB, a memory MM, and a display tube that displays numbers and characters.
DSP, printer PRT that prints receipts, etc.
It consists of a cassette tape device CMT, a magnetic card reader CRD, etc. The cassette tape device CMT is used to store the sales amount for each customer in the case of transactions using magnetic cards, so-called credit sales.

FIGS. 3A and 3B relate to one embodiment of the present invention.
This shows the key operation procedure in ECR. In the present invention, a card reading operation, such as inserting the card into the card slot of the ECR, may be performed before registering the details as shown in FIG. 3A, or as shown in FIG. 3B. As shown in the figure, after registering the details, the card sales key CK may be pressed and then the card reading operation may be performed. Alternatively, it is also possible to perform a card reading operation while registering details. Note that detailed registration is performed, for example, by pressing a number key NK indicating the sales amount and a department key DK indicating the department code of the sold product. In other words, Figures A and B show the procedure for registering details when a product with a department code of D1 and a price of 100 yen and a product with a department code of D2 and a price of 200 yen are sold. ing.

FIG. 4 shows each area provided in the memory MM of the ECR according to one embodiment of the present invention shown in FIG. That is, in the memory MM, there is a card read flag indicating that the card has been read.
FR, card reading buffer BR that stores the membership number and other card data, numeric buffer BN that stores the numeric data corresponding to the numeric key NK when the numeric key NK is pressed, and temporarily stores amount data. Amount buffer BA, transaction total buffer that sequentially stores the total transaction amount in one transaction
There are various buffers such as BT. Further, in the memory MM, a CMT output counter M that counts how many times data has been written to the cassette tape device CMT and an item buffer counter N that counts the number of registered products in one transaction are provided as counters. ing. Furthermore, the memory
In order to store the department code and amount for one transaction in order to write data to the cassette tape device, the MM has an item buffer that has multiple sets of department code field BiD and amount field BiA.
Bi is provided.

FIG. 5 shows the registration processing procedure performed by the central processing unit in the ECR. In the procedure shown in the same figure, first, use the magnetic card reader.
It is determined whether or not the card has been read in the CRD (step 101), and if the card has been read, the read data from the card reader CRD is stored in the card read buffer BR (step 101).
102), and sets the card reading flag FR to 1 (step 103). After the card reading flag FR is set to 1, or if the card has not been read as described above, the presence or absence of a key input is determined (step 104), and if a key input has been performed, the type of key that was pressed is determined. The following processing is performed for each. That is, if the numeric key NK is pressed (step 105), the numeric data from the key is stored in the numeric buffer BN (step 106) and the process returns to the starting point. If the department key DK is pressed (step 107), the contents of the number buffer BN are transferred to the amount buffer BA (step 107).
108) Clear the corresponding number buffer (step 109),
Next, set the contents of the item buffer counter N to 1.
(step 110) and presses the department key
The department code from DK is item number N
2nd department code field BiD _N and metal bar BA
The contents of the Nth amount column of the item value
BiA _N (steps 111 and 112), and then add the contents of the amount buffer BA to the contents of the transaction total buffer BT to obtain the transaction total buffer BT.
(Step 113), and then stores the department code corresponding to the pressed department key DK and the amount buffer BA as the transaction amount corresponding to the department code.
Print the contents of from the printer PRT (step
114). If the cash sell key CTK is pressed (step 115), the contents of the transaction total buffer BT are printed by the printer PRT (step 116).
After that, the item buffer counter N, card reading flag FR, and transaction total buffer BT are all cleared (steps 117 to 119). if,
If the card selling key CK is pressed (step 120), it is determined whether the card reading flag FR is set to 1 (step 121). As a result of this judgment, if the card reading flag FR is 1
If the card is not set to 1, the display DSP will display a card reading request requesting that the card be inserted into the card slot (step 1).
122). If the card is actually read after the card read request is displayed (step 123), the read data from the card reader CRD is stored in the card read buffer BR (step 124), and the card read flag is set. Set FR to 1 (step 125). If the card reading flag FR is set to 1 in this way, or as a result of the above judgment, the card reading flag FR has already been set to 1.
If it is set, the next process is to check the card data set in the card reading buffer BR, such as checking the expiration date (step 126). As a result of this check, if there is any problem, such as the expiration date has already passed, an error message is displayed, such as by sounding an error buzzer (steps 127, 128).
If there are no particular inconveniences (step 127), the printer
The member number in the card reading buffer BR and the total transaction amount in the transaction total buffer BT are printed from the PRT (steps 129, 130), and the CMT output counter is set to 1 (step 131). next,
The contents of the Mth column of the item buffer, i.e. BiD _M
Then, the contents of BiA _M are written to the cassette tape device CMT (step 132), the CMT output counter M is incremented by 1 (step 133), and the value of the item buffer counter N is decreased by 1 (step 134). Repeat this operation until the value of the item buffer counter N becomes 0, and after reaching 0 (step 135), the total transaction amount in the transaction total buffer BT and the membership number in the card reading buffer BR are combined. Write to cassette tape device CMT (step 136), card read flag
Clear both FR and total transaction buffer BT (steps 137 and 138).

According to the above processing procedure, at the processing start point, it is first determined whether or not the card has been read, and then the key input processing is performed.
Each time a key is pressed, it is determined whether or not the card has been read, and the card data is read, so that the card can be read at any time during statement registration.

Therefore, according to the present invention, the card reading operation, that is, the selection of whether to pay by card or by cash, etc., can be performed at any time before the closing operation of the registration process (before the end of the transaction). As a result, payment methods can be freely selected or changed depending on the cumulative amount or total amount of payments, and there is no need to inquire about payment methods from customers before registering details, making it easier to operate electronic cash registers. The degree of freedom increases.
