TECHNICAL FIELD The present invention relates to a POS terminal,
In particular, the present invention relates to a POS terminal and a sales processing method thereof for facilitating change amount modification.

[0002]

2. Description of the Related Art With the spread of computers, POS (Po
The POS terminal (electronic cash register device) connected to the int of Sales system is widely used not only in the retail business such as supermarkets and convenience stores but also in many restaurants handling money such as family restaurants and hotels. There is.

In order to use such a POS terminal, the cashier inputs the amount of deposit from the customer for the sales amount into the POS terminal. Then, after the settlement is completed, the change amount and the receipt (receipt) displayed on the display screen of the POS terminal are given to the customer. However, for example, the sales amount is 1000
When the amount of money is less than or equal to yen, the customer usually first gives one or more 10,000 yen or 1000 yen bills to the cashier. After the cashier operates the POS terminal on the basis of this amount of money to start the settlement process, a customer who does not want to carry a large amount of coins often searches for coins and makes additional payment.

As described above, when the customer later pays additional change such as coins, the cashier recalculates the change by himself without relying on the POS terminal, and hands the change to the customer.
However, since the cashier has completed the payment processing using the POS terminal, the receipt paid by the customer does not reflect the additional payment amount of the customer. Therefore, the details before the additional payment are printed on the receipt. For example, suppose that the customer paid 1,500 yen to the cashier when the sales amount was 1,234 yen. Cashier deposit 15
Enter 00 yen into the POS terminal. The change screen of 266 yen is displayed on the display screen of the POS terminal, the receipt is issued, and the settlement is completed. Here, it is assumed that the customer additionally paid 34 yen. The cashier recalculates a new change by mental arithmetic, derives a new change of 300 yen, and hands it to the customer.

[0005]

In the conventional POS terminal, as in the above example, the POS terminal sells 123 dollars.
4 yen is displayed, and cashier makes the first deposit from the customer 1
After entering 500 yen into the POS terminal and completing the payment,
It is assumed that the customer additionally pays a change of 34 yen in order to make a change. In that case, the cashier should pay the change 3 to the customer by mental calculation, regardless of the POS terminal.
I have to recalculate 00 yen. This reduces the work efficiency of the cashier and may cause an error in the recalculation process.

Further, since the POS terminal has completed the payment processing, the receipt has the details printed before the additional payment by the customer, which may cause a trouble with the customer regarding the change amount. . On the other hand, if the customer's additional payment is refused, the customer's dissatisfaction remains and the customer satisfaction is deteriorated. Furthermore, if the customer's payment is slowly waited so that the customer's additional payment does not occur, the work efficiency of the POS terminal is reduced, a long queue is formed in front of the cashier, and customer satisfaction is reduced.

BEST MODE FOR CARRYING OUT THE INVENTION The configuration and operation of a preferred embodiment of a POS terminal and a processing method thereof according to the present invention will be described below.
It will be described in detail with reference to the accompanying drawings.

First, FIG. 1 is a block diagram showing the configuration of a preferred embodiment of a POS terminal according to the present invention. This PO
The S terminal 10 includes an input unit 11, a CPU (central processing unit) 12, a ROM (read-only memory) 13, and a RAM.
(Random access memory) 14, a display unit 15, the CPU 12 described above, and a bus 16 interconnecting each unit.

In the POS system (or electronic cash register device) 10 shown in FIG.
It is a well-known data input device such as a keyboard or a touch panel for inputting the product name, unit price, quantity (quantity), amount paid by the customer, etc. of the product purchased by the customer (or sold to the customer). The CPU 12 performs a calculation process of the total amount of the customer's purchased merchandise and the like input by the cashier through the input unit 11, the consumption tax, and the change to be given (returned) to the customer.

Next, the ROM 13 stores a program for the CPU 12 to perform a predetermined processing operation. RAM1
Reference numeral 4 temporarily stores various data input by the cashier from the input unit 11 and data processed by the CPU 12 based on the various data. The display unit 15 is a display device that displays data from the CPU 12, such as a liquid crystal display panel. Bus 16 is from each unit to CPU 12 or CP
It transmits control signals and data from U12 to each unit.

Next, the change calculation procedure of the POS terminal 10 by the operation of the POS terminal 10 or the cashier shown in FIG. 1 will be described with reference to the flowchart shown in FIG. First,
The cashier receives the deposit from the customer (step S
0). Then, the cashier inputs this deposit into the input unit 11
The keyboard or the like is operated to input (step S1).
The CPU 12 of the POS terminal 10 subtracts the sales amount (including consumption tax) input in advance from this deposit to calculate the change (step S2). Next, the CPU 12 of the POS terminal 10 displays the deposit amount, the sales amount, the change, etc. on the display unit 15 (step S3).

The POS terminal 10 issues a receipt by a printing unit (not shown) based on the deposit, sales amount, consumption tax and change data sent from the CPU 12 (step S4). With the above processing, the normal settlement processing ends (step S5).

However, the POS terminal 10 and the settlement processing method therefor according to the present invention have the following features.
First, after the above-described normal sales process is completed, the sales data is saved in the RAM 14 (step S6). Then, it is determined whether or not to start the next customer sales process (step S7). When the next sales process is started (step S7: Y), the sales process of the previous customer is completed (confirmed), and the sales process of the next customer is performed in the same manner as step S0 and subsequent steps described above (step S8). .

On the other hand, when the next sales processing is not started (or before the sales processing of the next customer is started) (step S7:
N), it is judged whether or not there is a re-input of the deposit amount from the previous customer (step S9). When the deposit amount is re-input (step S9: Y), the cashier operates the input unit 11
Then, the total deposit amount is re-input (step S10), the process returns to step S2 described above, and the CPU 12 performs the following change calculation process again. If the total deposit amount is not re-input (step S9: N), the additional amount such as coins is re-input by the input unit 11 (step S11), the process returns to step S2 described above, and the change calculation by the CPU 12 is performed again. Process. In this way, the cashier can select and input either the full amount re-input of the deposit or the additional amount re-input.

Next, a specific example of the POS terminal sales processing operation according to the present invention will be described with reference to FIGS. FIG. 3A is a normal sales process shown in steps S0 to S4 in the flowchart of FIG. In other words, “sales data” is 720 yen for 3 items and consumption tax is 36 yen for a total of 756 yen, and “deposit data” from customers is 10 yen.
This is the case of 00 yen. In this case, the change 244 yen is displayed on the display unit 15 of the POS terminal. Further, in the "sales receipt", the above-mentioned sales data total of 756 yen, deposit 1000 yen and change 244 yen are displayed.

On the other hand, the example shown in FIG. 3B is an example in the case of re-inputting the "additional payment amount" in steps S0 to S7, S9 and S11 described above in the flowchart of FIG. That is, the “sales data” is 756 yen in total, which is 720 yen for the three items and 36 yen for the consumption tax, as in the case described above.
And pay 1000 yen as "deposit data",
This is the case when an additional 56 yen is paid. In this case, the display section 15 of the POS terminal 10 indicates 30
0 yen is displayed. Further, on the “sales receipt”, the above-mentioned sales data totaling 756 yen, deposit 1056 yen and change 300 yen are printed.

In the example shown in FIG. 3C, the "total deposit amount re-input" is performed in steps S0 to S7, S9 and S10 in the flowchart of FIG. Figure 3
As in the case of (B), the “sales data” is 3 items 72
The total is 756 yen, which is 0 yen and the consumption tax is 36 yen. And after paying 1000 yen as "deposit money", 56
This is a case where a mode is selected in which the yen is added and paid, and the cashier re-inputs the “total deposit amount” from the input unit 15.
In this case, 300 yen of change is displayed on the display unit 15 of the POS terminal 10. In addition, the sales receipt shows
It is similar to the case of (B).

The configuration and operation of the preferred embodiment of the POS terminal and the sales processing method thereof according to the present invention have been described above in detail. However, such an embodiment is merely an example of the present invention and does not limit the present invention in any way. Those skilled in the art can easily understand that various modifications and changes can be made according to a specific application without departing from the gist of the present invention.
