The present invention relates to a system for processing merchandise sales information, and more particularly, to a method of printing merchandise sales information.

Generally, a system for processing product information includes an electronic cash register and a point of sales terminal.

키→금액키→제품키 순으로 진행되었으며, 제 1 도(b)와 같이 인쇄되는 경우는 상품 및 금액을 등록한 후 반복키를 사용하는 경우가 있었다.In such a system, a conventional receipt printing form is implemented as shown in Figs. 1 (a) and (b). That is, when printed as shown in FIG.

In the order of key → amount key → product key, when printed as shown in FIG.

However, the printing method of FIG. 1 (b) does not use a quantity key, and in the case of the same article, it is printed by the sales number, resulting in the receipt printing speed and waste of printing paper, and inconvenient for customer confirmation. In the printing method of FIG. 1 (a), the product key is input after the quantity key differently from the human perception order, which may cause an error in key operation, and the product is misidentified as a product having a different price and quantity after printing. There was a problem that could have been.

Accordingly, an object of the present invention is to provide a receipt printing method that can reduce the amount of printing in a system for processing product sales information and at the same time convert the printing form into a form that is easy for the customer to understand.

Hereinafter, the present invention will be described in detail with reference to the drawings.

2 is a system block diagram for carrying out the present invention, wherein the keyboard central processing unit 10 outputs status information and data after decoding a key input on a keyboard to determine whether it is a normal key input, and based on the status information and data. A central processing unit 20 for outputting product sales information by executing calculation and table search, and a printer central processing unit for controlling the printer 40 to print a receipt for the product sales information ( 30) and a display central processing unit 50 for controlling the display unit 60 to display the product sales information. FIG. 3 is a flow chart for carrying out the present invention. The first process of printing the product date and time and the product name, and after checking the quantity key or not after performing the first process, calculates the total price by multiplying the quantity of the quantity key and the corresponding product by unit price Is a second process, and a third process of checking whether or not the closing key is not a quantity key in the second process, and returning it if it is not, and calculating and printing the combined price for all goods at the closing key date and time at the third process. A fourth step of returning after printing the initial message; a fifth step of checking whether the state item and the current state item are the same when the first product is not registered in the first step; and the first step when the item is the same in the fifth step. In the case of the above, after the product name is printed, the number of products is increased, the product calculates the total price, and for subsequent input, only the product unit is increased, the total price of the product is calculated, and the sixth process proceeds to the second process; If the item is different in step 5, after printing the total price of all items, printing the trade name of the current input item, and setting information on the number of items and the unit price, the second It comprises a seventh step of proceeding to the process.

Figure 4 is a printing form of the receipt printed according to the present invention, (a) section prints the goods and date, etc. in the initial message area of the receipt, (b) section is the corresponding product name, price, quantity and Section (c) is an area for printing product sales information such as total price, and section (c) is an area for printing information corresponding to subtotal.

Based on the above configuration, the present invention will be described in detail with reference to FIGS.

2 is a block diagram of a POS terminal of a merchandise sales information processing system for carrying out the present invention, which can process various information and data generated at the point of merchandise sales, and a receipt printing method according to the present invention. The printer central processing unit 30 receives the data of the main central processing unit 20 and processes it.

First, when a product is registered in step (A1), it is checked whether the product registration is the first product registration in step (A2). That is, step (A2) is a step of checking whether the product is registered for the first time after the closing key when registering the product. If the product is registered in the state where the OP FLG is 0, the product is determined as the first product.

If the first product registration in step (A2), proceed to step (A3) to print the product name of the current input, store the item code of the current input in the item register (ITEM Register) to indicate that the first product is registered Set the OP flag (OPFLG) to "1".

key)이고, 나머지 형태는 상품등록키형태이다.After performing step (A3), there may be two types of key inputs. One type is a quantity key (

key), and the remaining forms are product registration key forms.

First, the case of entering a quantity key will be described.

If the quantity key is input in step (A4), the number data (EA) generated by the numeric keys is set in step (A5), and the input quantity (EA) is input to the number of products IN0 + EA register (IN0 register) in step (A6). Add (IN0 ← IN0 + EA) and calculate the total price of the product (Tprice ← Tprice + EA * price). At this time, in step (A7) it calculates as much as the price of the corresponding product by the quantity key, and proceeds to step (A5) without printing.

Secondly, the procedure when the product key is input again with the first product registered is explained.

At this time, in step (A10) it is checked whether the item registered in the previous state and the item of the input is the same, and if it is the same, in step (A11) it is checked whether the value of the number of goods (IN0) is "1". In this case, if the number of products is "1" in step (A11), the process proceeds to step (A12) to print the unit price of the corresponding product, and in step (A13), the current input is added by adding "1" to the number of products (IN0) in the previous state. After that, the total price (Tprice ← Tprice + unit price) for the current product is calculated. If the number of products (IN0) is 2 or more in step (A11), the unit price of the product is already printed. Proceeding to step A13 without performing the step, the number of products is increased by one (IN0 ← IN0 + 1), and the current price of the corresponding product is calculated (Tprice ← Tprice + unit price). After performing step (A13), the process proceeds to step (A4). Steps (A4) to (A6) add the input quantity (EA) to the number of products (IN0) when the quantity key is input after product registration, and calculate the total price of the corresponding product according to the input quantity. The process of calculating the total price of the product according to the quantity entered after printing the unit price of the corresponding product when the same item as the previous state item is input.

Therefore, the product can be registered in two forms as described above, in which case the total price of the product is not printed.

Third, the process of printing the product price and registering the following product information will be explained.

When the current input item is different from the item in the previous state in step (A10), since the current input product is different from the product in the previous state, the price of the input product in the previous state must be printed. If the number of items is "1", it is checked. If the number of items is "1", the steps (A11) to (A13) or the steps (A4) to (A6) are not performed (that is, product registration). The number is "1"), so proceed to step (A16) to print the unit price for the product, and if the number of items is "1" or more, the steps (A11)-(A13) or (A4)- Since the step (A6) has been performed (that is, the number of the product registration number is "2" or more), the process proceeds to the step (A15) to print the number and the total price of the product. After performing the steps (A15) or (A16), in step (A17), the product name of the current input item is printed, and in step (A18), the price of the corresponding product name is set through the main central processing unit 20, and then set. After performing step (A19), the number of items is set to 1, the unit price of the corresponding product set in step (A18) is set, and then the process proceeds to step (A4).

After printing all the desired product sales information through the above process and inputting the finishing key, in step (A7), the finishing key is recognized, and in step (A8), the OP flag (OPFLG) indicating the presence or absence of the first product registration is reset ( "0") to prepare for the next customer's receipt print, calculate the price for the total sales product, obtain the total price, close the receipt of cash and change, and proceed to step (A9) to proceed as shown in FIG. After printing the initial message of receipt, proceed to step (A1) and prepare for the next state.

The process will be described again with reference to FIG. 4 as an embodiment.

The initial message of the receipt as shown in FIG. 4 (a) is already printed when the receipt is printed for the previous customer.

In step (A2), the current product registration prints the product name in the initial product registration date and time (A3) step after the closing key (DEPT 01), stores the current input item code in the item register in the previous state, and then registers the first product. Set an OP flag indicating.

Then, if the same product ("DEPT 01") is registered again, the current item and the previous state items are the same in step (A10), so in step (A11) it is checked whether the number of items (IN0) is 1. At this time, since the number of products is "1", the unit price "100" of "DEPT 01" is printed in step (A12). In step (A13), the number of products is increased to 2 and the total price is calculated as 200 and returned.

When the same product ("DEPT 01") is registered again, after performing steps (A10) and (A11), the number of products is increased to 3 in step (A13), and the total price is calculated as "300". Then, if the item ("DEPT 02") different from the previous state item ("DEPT 01") is input, it is checked in step (A14) that the number of products (IN0) is 1, but the number of products of "DEPT 01" is "3" (A15). In step), print "3 x 300". After (A17) prints the current input trade name "DEPT 02" and in step (A18) in step (A18) after reading the unit price "200" of the "DEPT 02" from the main central processing unit 20 (A19) The number of products of "DEPT 02" is set to "1", and the total price is set to "200".

After determining the sales information for the "DEPT 02" by performing steps (A11)-(A13), and then performs the step (A15) again to print the quantity and total price for the "DEPT 02". In this case, when the quantity key is used, the above process may be performed in steps (A5) to (A6). After the closing key is entered, it is reset to the OP flag "0" indicating whether the first product is registered and the total price for all products (DEPT 01, DEPT 02) is added together, and the total price "700" is printed. Prints a receipt initial message such as) and returns it.

As described above, printing papers can be saved by collecting and selling product sales information for the same item, and printing forms can be performed in the order of product name → unit price → quantity → total price for easier understanding by customers. There is an advantage that can provide.
