How to display the balance of an electronic cash register

The present invention relates to a balance display method of a cash register, and more particularly, to a balance display method of an electronic cash register which simultaneously displays the amount paid by the consumer as a commodity value and the balance minus the commodity value on one display. will be.

In general, a cash register refers to a device used to facilitate information management by processing various data associated with the sale of a product and informing the user of the result. It ranges from point of sales system to comprehensively manage the distribution economy such as research. Hereinafter, in the present specification, the term Electronic Cash Register (ECR), which means an electronic cash register controlled by a microprocessor, is used as a broad concept including a low-end cash register to a POS terminal.

1 is a system block diagram of a general electronic cash register. As shown in FIG. 1, a general ECR system kisses a key input unit 20 and a key input unit 20 generating a mode designation signal and various key codes for money registration, and a mode of the ECR according to the received key code. The central processing unit 10 for performing various functions in the designated mode, the ROM 70 in which the system operation program is embedded, the RAM 60 storing various data including deposit and withdrawal details, and the central processing unit ( Under the control of 10), a printer 80 for issuing documents for customer receipts and various processing results, a display 90 for displaying various information related to money transactions, etc. under the control of the central processing unit 10, and a predetermined key operation. And a drawer drive unit 50 for withdrawing the cash storage drawer at the time and a Real Time Clock (RTC) 100 providing information about the date and time. In addition, a bar code reader 30 for inputting bar code information of a product may be added to the high-end model ECR, and reference numeral 40 denotes an interface controller for relaying the bar code reader 30 and the central processing unit 10.

In the conventional ECR as described above, when the clerk tells the consumer the final total amount, the customer pays the amount. When the clerk enters the amount paid by the customer and hits the end key, the product is subtracted from the payment amount. The balance is shown on the display 90. That is, since only the last balance is displayed on the display 90, the customer cannot confirm whether the clerk recognizes the amount paid by the consumer and thus subtracts the commodity value.

The present invention has been made to solve the above-described problem, and provides a balance display method of the electronic cash register that displays on the display the amount paid by the consumer as a commodity value and the balance obtained by subtracting the commodity value at the same time Its purpose is to.

The balance display method of the electronic cash register of the present invention for achieving the above object is a balance display method of the cash register to display the balance obtained by subtracting the product value from the amount paid by the consumer purchased product value on the display of the cash register. The method of claim 1, further comprising: storing the amount paid by the consumer and the balance in different memory areas; And simultaneously displaying the respective amounts of money stored in the memory area on the display.

Hereinafter, a balance display method of an electronic cash register according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of a memory storage area for the balance display method of the electronic cash register of the present invention. As shown in FIG. 2, in order to execute the balance display method of the electronic cash register of the present invention, an area S1 to store a payment amount paid by the consumer as a commodity value in the memory and a balance amount to be returned to the consumer The area S2 to store the data is required. The amounts stored in this way are displayed together on the display 90 after the calculation is completed.

3 is a flowchart illustrating a balance display method of an electronic cash register of the present invention. As shown in FIG. 3, first, the ECR checks whether there is a key input through the kisscan in step S100, and if there is a key input, determines whether it is an item key input in step S110. The function of the key is processed, and if an item key is input, registration processing is performed in step S120. In step S130, if it is determined whether the subtotal key has been entered, the registration process continues according to the item key input, and if the subtotal key is input, that is, if there are no more purchase items, the total amount is calculated in step S140.

When the clerk tells the customer the total amount, the consumer pays the amount more than the total amount in bills. If the clerk inputs the amount paid by the customer in step S150, the amount is stored in the storage area S1. Then, if the end key is input in step S160, a balance obtained by subtracting the total amount of goods from the amount paid by the consumer in step S170 is calculated, and this value is stored in the storage area S2.

In step S180, the payment amount paid by the consumer stored in the storage areas S1 and S2 and the balance to be returned to the consumer are retrieved and displayed on the display 90 at the same time. Then, the receipt is issued in step S190, and the contents stored in S1 and S2 are deleted and then terminated.

4 is a view showing a form displayed when the balance display method of the electronic cash register of the present invention is executed. As shown in FIG. 4, when the consumer pays 5,000 won and receives the 1,500 won, the display 90 shows a form in which the consumer pays 5000 won, the remaining amount and the two amounts. It can be seen that the balance indication mark for distinguishing and the balance 1,500 won to be received by the consumer are displayed together.

The balance display method of the electronic cash register of the present invention is not limited to the above-described embodiments, and may be modified in various ways within the scope of the technical idea of the present invention.

According to the balance display method of the electronic cash register of the present invention as described above, the amount of money paid by the consumer and the balance to be received by the consumer are displayed together on the display, so that the clerk recognizes the amount paid by the consumer and subtracts the product value. Since it is possible to check the status of the receipt, it is effective to avoid the trouble of checking it again after the receipt is issued.
