The present invention relates to a method of operating a cash register and POS system, and more particularly, to a method in which the discount rate of a discount item is automatically applied during a discount period by presetting a discount period and an item.

In general, in the operation of an electronic cash register or a point of sales system (hereinafter referred to as POS), a discount key that is preset every time a sale of a discount item is processed during the sale period. %) Was always pressed for treatment.

For example, suppose that a customer bought a pants with a 30% discount rate.The key entry sequence required to press 10,000 with the numeric keys, press the item key for the pants, press 30, and then press the discount key (…%). .

Therefore, in the conventional cash register or POS, the discounted price should have been calculated by a number of key operations during the discount sales period. Therefore, it was necessary to perform an inefficient and inexpensive operation according to the number of sales items and the number of sales days. There was a problem causing operator error.

Accordingly, an object of the present invention is to provide a method of automatically setting a discount period and a discount rate of a discount item in a cash register or a POS so that the value of the discount item can be automatically adjusted according to the discount rate during the discount period by a simple key operation.

Hereinafter, the present invention will be described in detail with reference to the drawings. 1 is a system diagram of the present invention, a CPU 10 for controlling a system, a keyboard 20 serving as a key input unit, a ROM 30 incorporating a program, and a RAM storing data such as sales volume ( 40, a backup power supply unit 50 for protecting data of the RAM 40 in case of power failure, a display unit 60 for displaying the transaction status, a printer 70 for printing the transaction status, and a discount period. Timer 80 to control the time, a buzzer 90 to inform the error status, and a drawer (100) to operate at the end of the transaction by storing the transaction amount, etc. Figure 2 is a discount period and discount items FIG. 3 is a flowchart for processing items according to the preset state after performing FIG. 2, FIG. 4 is a mode switch on the keyboard, and FIG. 5 is a key matrix constituting the keyboard.

The present invention will be described in detail with reference to the first, second, third, fourth, and fifth embodiments in the above-described configuration.

The CPU 10 scans the keyboard 20 to check key input and analyzes input for a corresponding key when key data is input through the keyboard 20.

When setting and canceling the discount period, place the mode switch of the keyboard 10 as the fourth degree in the preset and press the corresponding key of the keyboard 20 as the fifth degree according to the program embedded in the ROM 30. The period is set and reset, and when the discount period is set, it is written in a predetermined area of the RAM 40, and the timer 80 controls the progress of the period.

In addition, the discount rate for the discounted item is also written in a predetermined area of the RAM 40, and the CPU 10 reads the preset amount from the RAM 40 and displays it on the display unit 60 according to the input item key. The amount of money is printed through the printer 70.

At this time, if an error occurs, the CPU 10 notifies the user of the error state by driving the buzzer. When the CPU 10 recognizes that the discount period has ended by the control of the timer 80, the transaction data input through the keyboard 20 then returns to its original state before the discount amount preset and performs the corresponding function.

The flow according to the invention proceeds as follows. Here, the preset amount refers to the amount that the preset amount is displayed and printed when the user presses the item key field instead of entering the amount by the numeric keys from the transaction after the preset when the user frequently trades the amount to be traded in a specific item key. .

When a user tries to perform a discount on some items during a certain period of time after purchasing a cash register or a POS, the flow rate is adjusted in consideration of the discount period and the discount rate for the items to be discounted in the same flow as in the second step.

First, the process of setting the discount period in FIG. 2 is performed by setting the keyboard 20 and the mode switch as shown in FIG. 4 to a preset position and entering the start point of the discount using the same key as in FIG. The key is selected to set the start point of the discount period, and the end point of the discount is set as described above.

In addition, select the item to be discounted and enter the amount and discount rate corresponding to the item.

)를 이용하여 세트 시키는데 제 2 도와 같이 세팅했다고 가정한다.Here, the item to be discounted is the item key (item of the keys such as the fifth degree of the keyboard 10)

Let's assume that we set with 2nd degree.

After performing the preset mode as shown in FIG. 2 and performing the item processing routine as shown in FIG. 3, the data preset in FIG. 2 is stored in the RAM 40.

When key data is input through the keyboard 10 as shown in FIG. 5, the CPU 10 analyzing the key data reads the time information from the timer 80 and compares it with a preset discount period. It clears the set discount rate, checks whether it is a preset amount, and checks whether the input key data is a preset item even at a discount date and time.

If the item is not a preset item, enter the instantaneous item amount using the numeric keys. If the item is a preset item, enter the item key. Read the discount rate of the item and move it to the instantaneous discount rate area of the RAM 40. Then, multiply the instantaneous item amount by the instantaneous discount rate to convert the discounted amount and subtract the discounted amount of the item from the instantaneous item amount. Displayed through (60) and printed on the resin through the printer 70, and adds the current content to the information of the item that has been accumulated and sold so far.

의 바지로 가정하여 설명한다.The item processing routine of FIG. 3 is a preset amount of 10,000 won and a discount rate of 30%

It is assumed to be pants.

이므로 프리세트 금액 10,000원을 램(40)의 순간 품목 금액 영역으로 옮기고 품목

의 할인율인 30%를 읽어 램(40)의 순간 할인율 영역으로 옮긴후 순간 품목금액인 10,000원과 순간 할인율인 30%를 곱하여 할인금액인 3,000원을 구한다.Item which is preset to read time information from timer 80, and to confirm discount period and to check whether it is a preset item

Move the preset amount of 10,000 won to the instantaneous item amount area of RAM 40

The discount rate of 30% is read and transferred to the instantaneous discount rate area of the RAM 40. The instantaneous item amount 10,000 won is multiplied by the instant discount rate 30% to obtain a discounted amount of 3,000 won.

정보에 내용을 추가시킨다.After subtracting the discounted amount from the instantaneous item price, 7,000 won becomes the instant item amount, which can be displayed through the display unit 60 and the printer 70.

키를 누르면 프린터(70)를 통하여 날자등의 정보를 인쇄하여 소비자에게 영수증을 제공할 수 있다.After the user of the same keyboard 10

When the key is pressed, the printer 70 may print information such as a date and provide a receipt to the consumer.

품목과 같이 할인되지 않는 품목의 판매도 프리세트 금액으로 판매가 가능하다.As above

An item can be issued a discounted discount during the discount period by pressing the item key without pressing the discount key.

Sales of items that are not discounted, such as items, can also be sold at preset prices.

정보에 현재의 내용을 추가한다.Also, at the end of the discount period,

If you press the key, the time information is read through the timer 80 and the discount period is not compared with the preset discount period.

Clear the preset discount rate for the key so that no discount is applied and move the preset amount of 10,000 won to the instant item amount area of the RAM 40.

The discount rate is transferred to the instantaneous discount rate area of the RAM 40. Since the discount rate is 0, the discount amount is also 0, and the item amount 10,000 won is displayed through the display unit 60 and printed on the resin paper through the printer 70.

Append the current content to the information.

As described above, in the case of a retailer with frequent sale periods and a large number of unit price presets, the amount of items can be calculated and displayed and printed by one key operation if only the discount period and the discount rate are preset. It can improve office efficiency, eliminate mistakes caused by user's malfunctions, and automatically recover after the discount period, and it is convenient to use. It is possible to calculate the price according to the discount rate without changing the product price attached to the label) and there is an advantage that can be displayed on the receipt.
