Hereinafter, with reference to the accompanying drawings will be described in detail the method for displaying the amount of money in an electronic cash register according to an embodiment of the present invention.

2 is a block diagram of a memory storage area for a method for displaying the amount of money of the electronic cash register of the present invention. As shown in FIG. 2, in order to execute the method for displaying the amount of money of the electronic cash register of the present invention, an area S1 for storing the total amount calculated by registering and processing a product purchased by the consumer on the RAM 60, There is a need for an area S2 for storing the payment amount paid as the commodity price and an area S3 for storing the balance to be returned to the consumer, which is a sum subtracted from the payment amount.

After the calculation is completed, the stored amounts are alternately displayed in the order of the total amount and the balance, the payment amount and the balance, and the two amounts are divided and displayed on the display 90.

3 is a flowchart illustrating a method for displaying the amount of money of the electronic cash register of the present invention. As shown in FIG. 3, the ECR first performs a kisscan in step S100, and as a result, it is determined whether there is a key input in step S105. If there is no key input, it continues to kisscan, and if there is a key input, it is determined whether the item key is input in step S110. If not, the function of the corresponding function key is processed in step S115, and if the item key is input, the step ( The registration process is performed in 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 entered, that is, if there are no more items purchased by the consumer, the total amount is calculated in step S140. The amount is displayed on the display 90 and printed by the printer 80. At this time, the total amount of money is stored in the specific storage area S1 on the RAM 60. Then, when the clerk tells the consumer the total amount, the consumer pays the amount of the bill in more than the total amount, and in step S150, when the clerk inputs the amount paid by the customer, the amount appears on the display 90. It is printed by the printer 80 and stored in the storage area S2 on the RAM 60. Then, in step S160, it is determined whether the end key is input, and if the end key is not input, an error is displayed. If the end key is input, the balance is calculated by subtracting the total amount of goods from the amount paid by the consumer in step S170. This value is stored in the storage area S3.

In step S180, the total amount of goods purchased by the consumer stored in the storage areas S1 and S3 and the balance to be returned to the consumer are retrieved and displayed on the display 90 at the same time. Then, when a certain time passes, the payment amount that the customer stored in the storage areas S2 and S3 and the balance to be returned to the customer are retrieved at step S185 and displayed on the display 90 at the same time. In the next step (S190) it is determined whether the receipt is finished, that is, the step (S180) or less is repeated until the product information of the next customer. The total amount and balance, payment amount and balance are displayed alternately, so the effect of confirming the amount becomes apparent.

As shown in FIG. 4, since the total amount of goods purchased by the consumer is 6500 won and the amount paid by the consumer is 10,000 won, the balance shown by the consumer is 3500 won, which is displayed on the display 90. (A) shows from the left that the total amount of goods purchased by the consumer is 6,500 won, the balance is a balance mark to distinguish the two amounts, and the balance of 3,500 won to be received by the consumer is divided and displayed on the display 90. Able to know. At intervals of time, the display 90 changes from the screen (A) to the screen (B), where the screen (B) shows the balance of 10000 won, the balance paid by the consumer from the left, to distinguish the two amounts. It can be seen that the balance indication mark and the balance 3500 won to be received by the consumer are divided and displayed on the display 90. At this time, one of the two amounts may be blinked to facilitate the distinction, that is, the balance may be displayed normally and the total amount and the paid amount may be blinked at the time of display in order to more clearly confirm the effect of the amount.

The screens (A) and (B) will be displayed alternately until the next customer's product information is entered.
