Description

The present invention relates to a receipt issuing device used for an electronic cash register or a POS (point of sale information management) terminal.

[Prior Art] For example, in a POS terminal, when a product code of a sold product is input from a keyboard, a product name and unit price set in advance corresponding to the product code are called, and a price is calculated based on the unit price. The price is printed out on the receipt. In addition, fixed data indicating the content of the price, such as the product name and the product code, is printed at the same time corresponding to the price.

In this case, the number of characters that can be printed on one line of the receipt is limited. On the other hand, the number of characters varies depending on the number of points purchased. Therefore, depending on how the product name is set, the price and the corresponding fixed data may not be printed in one digit. In such a case, conventionally, a part of the fixed data is omitted and edited so that the fixed data is contained in one line, and then the print output is performed on the receipt.

For example, Figures 6 and 7 are examples of printing on Receipt 1 that can print up to 22 characters per line. In this case, the tax type mark (but not printed for non-taxed products) is printed with 2 characters, the product code is printed with the next 4 characters, and the product name and price are printed with the remaining 16 characters. However, a space for at least 2 characters is required between the product name and the price.

In the case of the example shown in FIG. 6, the price of the sold product is 150 yen and 3
Since it is a character, the name (11 characters) and the price of 3 characters fit within 16 characters even if the space of 2 characters is taken into consideration. Therefore, the sixth
As shown by P in the figure, the product code, the product name, and the price are all printed in one line.

On the other hand, in the case of the example in FIG.
Since it is 00 yen and has 4 characters, considering the space for 2 characters, the name (11 characters) and the price of 4 characters cannot fit within 16 characters. Therefore, as shown by Q in FIG. 7, the final letter "K" of the name is omitted and the product code, the product name and the price are printed in one line.

[Problems to be Solved by the Invention] As described above, in the conventional apparatus for printing and issuing money data such as the price of the sold product and the total price thereof on the receipt together with the fixed data indicating the data content, When the number of characters between the fixed data and the corresponding fixed data does not fit in one line of the receipt, omit part of the fixed data
I was editing to fit in the line. Therefore, there was a problem that the omitted fixed data became unclear.

Therefore, according to the present invention, when the number of characters of variable data such as monetary data and fixed data corresponding to the variable data does not fit on one line of the receipt, the variable data and the fixed data have predetermined positions corresponding to two consecutive lines. It is intended to provide a receipt issuing device in which fixed data can be printed in a perfect form without omission of fixed data, and the variable data printed on two lines and the fixed data can be easily confirmed. is there.

[Means for Solving the Problems] According to the present invention, variable data relating to the price of each product sold to one customer is printed at a predetermined position on a receipt together with fixed data including a product name indicating the data content. Every time the variable data to be printed on the receipt is generated, the receipt issuing device that issues the judgment determines whether the result of adding the number of characters of the variable data and the number of characters of the product name of the fixed data is less than or equal to the preset number of characters. And a print control means for printing variable data and fixed data at predetermined positions corresponding to each of two consecutive lines when the number of characters exceeds a predetermined number. is there.

[Operation] By taking such a means, every time variable data to be printed on the receipt is generated, it is determined whether or not the number of characters of the variable data and the number of characters of the product name of the fixed data are added is less than or equal to a predetermined number of characters. To do. If it is determined that the number of characters is less than or equal to the predetermined number of characters, the fixed data and the variable data are printed at the predetermined positions on the same line. On the other hand, when it is determined that the number of characters exceeds the predetermined number, the variable data and the fixed data are printed at the predetermined positions corresponding to each of two consecutive lines.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the present embodiment, a case will be described in which the POS terminal that conventionally issued the receipt 1 as shown in FIGS. 6 and 7 is improved.

FIG. 1 is a block diagram showing a schematic configuration of the POS terminal. In the figure, 11 is a CPU (central processing unit) that constitutes the main body of the control unit, and incorporates various arithmetic circuits, memory control circuits, etc. to execute various arithmetic processes based on input data and to connect the bus line 12 ROM (Read Only Memory) where fixed data such as program data is stored via
A memory 13 and a RAM 14 that stores variable data such as input data and arithmetic processing data are operated.

In addition, a clock circuit 15 that measures the current time, a transmission control circuit 18 that controls data transmission / reception with a file processor 17 that is a higher-level model connected via a line 16, and "registration".
From the keyboard 21 where various keys such as I / O port 20 for inputting signals from the mode switch 19 that switches various business modes such as “payment” and “setting”, product code input keys, registration closing keys, etc. A keyboard circuit 22 for inputting and processing key data, a display control circuit 24 for driving and controlling a display device 23 for displaying the product name, price, total amount of sold products,
The printer drive circuit 26 of the printer 25 that prints on receipts and journals, and the I / O port 29 that outputs a drive signal to the drawer opening device 28 that opens the drawer 27, etc. to the CPU 11 via the bus line 12. It is connected.

The file processor 17 is composed of, for example, a host computer, and has a product file 30 in which product information such as product name, unit price, tax type, etc. of the product is preset corresponding to the product code given in advance for each product. There is.

FIG. 2 shows a data format for one product in the product file 30. As shown in the figure, an area for four characters is secured as a product code, an area for 11 characters is secured as a product name, and a unit price is 5 An area for characters is secured, and an area for two characters is secured as a tax type.

On the other hand, the RAM 14 has a sales registration memory for accumulating sales data of each registered product, a total amount memory for storing the total amount of the products sold to one customer, and an external product among the products sold to one customer. Various memories such as an external tax total memory for storing the total amount of tax products are formed. Further, as shown in FIG. 3, a print buffer 31 for storing print data for one line of receipt (22 characters) and a region 32 of the print control flag F are also formed.

Then, the CPU 11 executes the process shown in the flow chart of FIG. 4 when the sale item is registered by operating the keys of the keyboard 21 while the “registration” mode is selected by the mode switch 19. It is program controlled. That is, when a product code is input by the product code input key of the keyboard 21, an inquiry message of the product code is created and an inquiry about product information is made to the file processor 17 via the transmission control circuit 18. .

Here, when the file processor 17 receives the inquiry message for the product code, the file processor 17 searches the product file 30 to check whether the inquired product code is set. If it is set, the product information such as the product name, unit price, tax type, etc. corresponding to the product code is read out and embedded in the normal response message and returned. If it is not set, a negative response message is sent. It is configured to reply.

Therefore, when the CPU 11 receives the normal response message from the file processor 17 via the transmission control circuit 18 within a fixed time, it calculates the price based on the unit price in the message. Then, this price is added to the sales registration memory and the total amount memory of the RAM 14. If the tax type in the message is "external tax", the above price is also added to the external tax total memory.

Then, the calculated price is displayed on the display unit 23 together with the product name in the message. Further, the number of characters (digits) of the above price and the number of characters of the product name are added, and it is checked whether the sum is "14" or less (determination means).

By the way, the above "14" is a value defined only in this embodiment,
The maximum character spectrum of one line of the receipt in this embodiment is 22 characters, and when printing the price of the sale item,
Print the tax type mark (but not printed for tax-excluded products) with the first two characters, and the product code with the next four characters,
This is because the product name and price are set to be printed with the remaining 16 characters, but a space of at least 2 characters is required between the product name and the price. In other words, if the sum of the number of characters in the price and the number of characters in the product name is 14 characters or less excluding spaces, it will not fit on one line of the receipt.

Then, the sum of the number of characters in the price and the number of characters in the product name is "1
In the case of "4" or less, after setting the print control flag F of the area 32 in the RAM 14 to "1", the tax mark corresponding to the tax type in the message is set in the first two characters area of the print buffer 31 ( (Do not set if "external tax"), the product code in the message for the next 4 characters, the product name in the message for the remaining 16 characters, and the calculated price is 2 between the product name and the price. Set a space for each character. Then, the printer 25 is drive-controlled to print one line of the contents of the print buffer 31 on the receipt and the journal. After that, since the print control flag F is set to "1", the print buffer 31 is cleared, and then this process ends.

On the other hand, if the sum of the number of characters in the price and the number of characters in the product name exceeds "14", the print control flag F in the area 32 in the RAM 14 is reset to "0" and then the print buffer 31
Set the tax mark in the first 2 characters of the area, the product code in the next 4 characters, and the product name in the remaining 16 characters. Then, the printer 25 is drive-controlled to print one line of the contents of the print buffer 31 on the receipt and the journal. Next, since the print control flag F is reset to "0", the flag is set to "1" and the print buffer 31 is cleared once. After that, the price is set so that the least significant digit of the price comes in the last area of the print buffer 31, and the printer 25 is drive-controlled to print one line of the contents of the print buffer 31 on the receipt and the journal. After that, since the print control flag F is set to "1", the print buffer 31 is cleared, and then this process ends. (Printing control means) In the present embodiment configured as described above, the product code "001", the product name "ABCDEFGHIJK", the unit price "150 yen",
Consider a case where the product A of the tax type “external tax” is set in the product file. In this case, when a customer who purchases the product A appears, the clerk operating the POS terminal operates the product code key on the keyboard 21 to key in the corresponding product code “001”. Then, the product code “001” is inquired to the file processor 17, the product file 30 is searched, and the product name “ABCDEFGHIJK” corresponding to the product code “001”, the unit price “150 yen”, the tax type “ "External tax" is obtained.

Here, when the customer purchases only one item, the price is "150 yen", and the number of characters (digits) of the price is three characters. On the other hand, the product name "ABCDEFGHIJK" has 1 character
It is one character. Therefore, since the result of adding the number of characters of the product name and the price is "14" or less, the price which is the amount data indicated by the fixed data of the tax mark, the product code and the product name is displayed in the print buffer 31. Set at the same time. As a result, the product name is printed in one line as shown in FIG. 6P.

On the other hand, if the customer purchases 10 items, the price is "1500 yen" and the number of characters (digits) of the price is 4 characters. Therefore, since the result of adding the number of characters of the product name and the price exceeds "14", the tax mark, the product code and the fixed data of the product name are first set in the print buffer 31. After printing the fixed data, the price is set in the print buffer 31. As a result, the fifth
As shown in Figures R1 and R2, the product name and price are printed in two lines.

As described above, according to the present embodiment, when the sum of the number of characters of the product name of the registered product for sale and the number of characters of the price of the registered product does not fall within the preset number, the product name and the price are different from each other. Since the lines can be printed separately, it is not necessary to omit a part of the product name and edit the data for one line as shown in the conventional example of FIG. Therefore, the product name can always be printed in receipts in full form regardless of the size of the price, making it possible to issue a receipt that is easy to understand.

Although the product name and price of the sold product are printed in one line or two lines in the above embodiment, the present invention is not limited to this, and the fixed amount of data indicating the total amount and the contents of the amount ( It can also be applied to “current total” etc.) and fixed data (“tax (3%)” etc.) indicating the tax amount and the content of the amount. Further, the present invention is not limited to the POS terminal, but can be applied to those which issue receipts such as electronic cash registers and electronic fee scales.

[Effects of the Invention] As described in detail above, according to the present invention, when the number of characters of variable data such as amount data and corresponding fixed data does not fit on one line of the receipt, the amount data and the fixed data are received. Is printed at a predetermined position corresponding to each of two consecutive lines, the receipt data can be printed in perfect form without omitting the fixed data, and the confirmation of the variable data and the fixed data printed on two lines is possible. You can easily.
