Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to an electronic cash register used as a terminal for product sales registration in a (point-of-sale information management) system, and in particular, to one having a function of issuing a ticket such as a receipt or a credit sales voucher using receipt paper. .

[0002]

2. Description of the Related Art Generally, an electronic cash register has a printer for printing and issuing a receipt.

FIG. 9 shows the main structure of the printer. In this printer, a belt-shaped receipt paper 1 pulled out from a roll body is used as a paper guide platen 2a on the platen inlet side.
2b so that the platen 3 is wound around a half circumference, and further guided by the paper guides 4a and 4b on the platen outlet side to pass through the cutter unit 5, and then discharged to the outside from a receipt discharge port (not shown). A conveyance path for the receipt paper 1 is formed.

The platen 3 and a paper feed drive roller (not shown) are intermittently rotated by driving the stepping motor 6 to convey the receipt paper 1 by a predetermined amount along the conveyance path. Each time a fixed amount of conveyance is performed, one line of data is printed on the receipt paper 1 by the line thermal type print head 7 provided so as to face the platen 3. Here, the print head 7 and the platen 3 form a printing unit.

Further, for example, by operating the cutter unit 5 in response to an operation input of a closing key that declares the end of registration of all the products purchased in one transaction, the receipt paper 1 is cut and one transaction is completed. Issue a receipt.

Here, the print position P by the print head 7 and the cutting position Q in the cutter unit 5 have to be separated from each other due to the structure of the printer. Therefore, if the distance between the printing position P and the cutting position Q is converted into the number of printing lines and it is X lines, after the data of the last line of the receipt (transaction number, responsible person number, etc.) is printed by the operation input of the closing key. , It was necessary to control so as to cut the receipt paper 1 after feeding X rows.

Therefore, conventionally, after printing the data of the last line of the receipt for one transaction, the receipt paper 1 is fed while printing the store name, logo mark, etc. as the header data of the receipt for the next transaction, and the X line is fed. If it is done, the receipt paper 1 is controlled so as to be cut so that no unnecessary blank space is generated at the upper part of the issued receipt.

Some electronic cash registers equipped with this type of printer have a receipt ticket issuing function. This receipt ticketing function is provided with a receipt key for instructing receipt ticketing, and when the receipt key is operated after the closing key is operated, the registration end is declared by the closing key operation input. It is a function of creating receipt data relating to a transaction, printing the receipt data on the receipt paper 1 by the printer, cutting the receipt paper 1, and issuing a receipt.

FIG. 10 shows an example of receipt printing when a receipt is issued. That is, there is a transaction with a total amount of 1000 yen (transaction number 9999), and in response to the closing key operation for this transaction, the area G1 is first printed, cut at the cutting line L1, and the receipt R1 is issued. . Next, in response to the receipt key operation, the area G2 is printed, cut along the cutting line L2, and the receipt R2 is issued.

It should be noted that the receipt R2 is a landscape format in which characters are rotated 90 degrees to the left with respect to the receipt R1. r4 and the like are provided, and the total transaction amount is printed in the amount column r2 and the date data is printed in the date column r4.

[0011]

However, the conventional electronic cash register having the receipt ticket issuing function has the following problems to be solved. That is,
Due to the structure of the printer, in order to reduce the blank area of the receipt, after printing the data of the last line of the receipt R1 or after printing the data of the last line of the receipt R2, the header data of the receipt for the next transaction (store name / logo part ) Since it is necessary to cut the receipt paper 1 after printing H,
As shown in, the header data H was also printed on the receipt R2. This header data H is completely unnecessary for the receipt R2 and is not well formed. Therefore, the printed portion of the header data H is separated and handed to the customer, but the separated printed portion of the header data H is forced to be discarded, resulting in waste of paper.

When a receipt is issued to a customer, it is convenient if the copy can be stored at the store side. Currently, the exclusive receipt paper used in many stores is a copy type,
The reality is that one is given to the customer and the rest is kept as a reserve by the store.

Therefore, it is desirable that an electronic cash register having a receipt ticket issuing function is configured to issue two identical receipts in succession so that copies can be stored. However, in this case as well, since the header data is printed on both receipts, it is necessary to cut off the print portion of the header data at least for the person handing it to the customer, and waste of paper cannot be avoided.

Such a problem also applies to an electronic cash register or the like having a function of processing a payment service by credit and printing and issuing a credit sales voucher after issuing a receipt for the transaction using a receipt paper.

Therefore, according to the present invention, the structure of the printer is not changed, and the portion on which the header data of the receipt for the next transaction is printed is not discarded wastefully, and a receipt which is well-formed using the receipt paper can be used. It intends to provide an electronic cash register that can obtain a ticket and a copy of this ticket.

[0016]

SUMMARY OF THE INVENTION According to the present invention, data of a product registered for sale by a product registration unit is printed on a receipt paper pulled out from a roll body by a printing unit, and all the products can be purchased in one transaction. The receipt header data for the next transaction is printed on the receipt paper in response to the operation input of the closing key that declares the end of product registration, and then the receipt paper is cut by the cutter unit fixed on the downstream side of the printing unit. In addition to a printer that issues receipts, a ticket issuing key that issues a ticket is issued, and when the ticket issuing key is operated after the closing key is operated, the ticket related to the transaction in which registration end is declared by the operation input of the closing key Data is created, this ticket data is printed on the receipt paper by the printing unit, then the header data is printed, and then the receipt paper is cut off by the cutter unit. In the electronic cash register configured to do so, a duplicate ticket data creating means for creating the duplicate ticket data for the ticket data in response to the operation input of the ticket issuing key after the operation input of the closing key, and the creating means A printing means for printing the printed backing ticket data on the receipt paper in the printing section is provided, and the printing of the backing up ticket data is performed after the printing of the backing up ticket data by the backing ticket printing means. is there.

[0017]

According to the present invention having such a configuration, when the sales registration of all the products purchased in one transaction is performed by the product registration means and the termination of the registration is declared by the operation input of the closing key, the transaction is executed. A receipt will be issued. At this time, the receipt header data for the next transaction has already been printed on the receipt paper.

In this state, for example, when a ticket issuing key for instructing receipt issuance is operated, receipt data for the previous transaction and its copy data are created. Then, the copy data is first printed after the header data, and then the receipt data is printed. After that, if the receipt header data for the next transaction is printed, the receipt paper is cut at the boundary between the receipt data printing area and the receipt header data printing area for the next transaction, and the receipt receipt is printed. A book is issued.

Therefore, by separating this copy receipt at the boundary between the copy data printing area and the receipt data printing area, header data is not printed in the receipt data printing area, and the receipt data is not printed. It will be good. On the other hand, although the header data is printed in the copy data printing area, it is not a problem because it is a copy on the store side, and there is no waste of separating and discarding this header data printing portion.

Thereafter, the print data in the print buffer 33 is read line by line from the beginning, and the printer controller 2
It is sent to the printer 16 via 7 to print on the receipt paper 1 (copy ticket printing means).

In this way, when the printing of the receipt copy is completed, next the face value column 4 of the receipt body print format data preset in the print data setting table 34.
2 is the content of the item “receipt face value” area of the receipt item data memory 35, the date column 44 is the content of the item “receipt issue date” area, and the receipt number column 45 is the item “receipt number”. When the print data of the receipt main body is created by rewriting the contents of the area with the characters rotated by 90 degrees to the left, the print data is drawn in the print buffer 33.

Next, after the print line number counter N in the counter memory 36 is cleared to "0", the print data in the print buffer 33 is read line by line from the beginning and sent to the printer 16 via the printer controller 27. hand,
Printing is performed on the receipt paper 1. At this time, every time one line of print data is sent out, the print line number counter N is incremented, and this counter N performs printing corresponding to the distance between the print position P by the print head 7 and the cutting position Q by the cutter unit 5. If the number of lines X matches, a paper cutting command is supplied to the printer 16 to cut the receipt paper 1 by the cutter unit 5.

After that, the remaining print data in the print buffer 33 is read line by line from the beginning and sent to the printer 16 via the printer controller 27 to print on the receipt paper 1.

When printing of the receipt body is completed in this way, the print line number counter N in the counter memory 36 is cleared to "0" and the store name / logo preset in the print data setting table 34 is set. The copy print data is drawn in the print buffer 33. Then, the print data in the print buffer 33 is read line by line from the beginning and sent to the printer 16 via the printer controller 27 to print on the receipt paper 1. At this time, the print line number counter N is incremented each time one line of print data is sent.

When all the print data in the print buffer 33 has been sent out, an empty feed command for one line is supplied to the printer 16 to empty the receipt paper 1 and the print line number counter N is set. When the counter N is counted up and the counter N coincides with the number of print lines X, a paper cutting command is supplied to the printer 16 to cut the receipt paper 1 by the cutter unit 5. This is the end of the receipt key processing.

It should be noted that the printer 16 is configured to print data indicating that a receipt has been issued (for example, "receipt issuance") on the journal paper.

In the present embodiment thus constructed, for example, a transaction (transaction number 9) for a total amount of 1000 yen is now performed.
999) and the closing key 12e for this transaction is operated and input, in the example of printing the receipt paper 1 shown in FIG. 6, the area G1 is printed and cut by the cutter 5 at the cutting line L1. The receipt R1 is issued from the receipt issuing port 17. At this time, the receipt header data (store name / logo portion) H1 for the next transaction is already printed on the receipt paper 1.

Next, when the receipt key 12a is operated and input, first, the face value column 46 of the receipt copy print format data shown in FIG. 4 (b) shows the item "receipt face value" in the receipt item data memory 35. In the contents of the area, the date column 47 is the item. In the contents of the receipt receipt date area, the receipt number column 4
8 is rewritten with the contents of the item “receipt number” area to create the receipt print data. Then, the print data is output to the printer 16 and the area G3 is printed.

Next, the face value column 42 of the receipt body print format data shown in FIG. 4 (a) shows the contents of the item "receipt face value" area of the receipt item data memory 35.
The date column 44 is rewritten to the contents of the item “receipt issuance date” area, and the receipt number column 45 is rewritten to the contents of the item “receipt number” area by rotating 90 ° to the left to create the print data of the receipt body. To be done. Then, this print data is output to the printer 16 and the area G4 is printed.

At this time, the cutter unit 5 is activated when X lines are printed from the beginning, the receipt paper 1 is cut at the cutting line L3, and the receipt copy R3 is displayed on the receipt issuing port 1.
Tickets will be issued from 7.

Next, the store name / logo print data is output to the printer 16 and the header data H2 of the receipt for the next transaction, that is, the area G5 is printed. After printing, the cutter unit 5 is activated, the receipt paper 1 is cut at the cutting line L4, and the receipt body R4 is issued from the receipt issuing port 17.

Therefore, the store handes the receipt body R4, which has been issued later, to the shopper, and stores the receipt copy R3, which was issued earlier.

Therefore, the receipt body R4 given to the shopper
Since header data such as store name and logo mark are not printed on the product, it looks good and gives a good impression to customers. On the other hand, due to the structure of the printer 16, the header data printed portion of the receipt for the next transaction, which must be printed in response to the operation input of the closing key 12e, is used as a part of the receipt copy R3. Since R3 is stored by the store side, there is no waste such as separating and discarding the header data print portion, which is efficient.

When the receipt body R4 is printed, the number of print lines is counted, and when the print line number X corresponding to the distance between the print position P by the print head 7 and the cutting position Q by the cutter unit 5 is reached, the cutter unit By operating 5 to cut the receipt paper 1, the receipt copy R3 and the receipt body R4 are automatically cut to issue a ticket. Therefore, it is not necessary to cut the receipt copy R3 and the receipt body R4.

Although the receipt copy R3 and the receipt body R4 are automatically cut and issued in the above embodiment, the cut line 7 is provided between the receipt copy R3 and the receipt body R4 as shown in FIG.
1 and the tally field 72 may be printed and ticketed without cutting, and the clerk may separate after tallying.

FIG. 8 shows the receipt key processing of the CPU 21 in the other embodiment. The RAM 22 is preset with print data corresponding to the cutout line 71 and the print area G6 of the tally field 72.

When the CPU 21 detects the operation input of the receipt key 12a subsequent to the operation input of the closing key 12e in the "registration" mode, each item data is set in the receipt item data memory 35, and each item data is set. The configuration from the receipt copy print format data to create the receipt copy print data, output it to the printer 16 and print the receipt is the same as that of the above-described embodiment.

Now, in another embodiment, the receipt copy R3
After completing the printing of, the print data corresponding to the cutoff line 71 and the print area G6 of the tally field 72 is drawn in the print buffer 33. Then, the print data in the print buffer 33 is read line by line from the beginning and sent to the printer 16 via the printer controller 27 to print on the receipt paper 1. As a result, the cutoff line 71 and the tally field 72 are printed following the print data of the receipt copy.

Thereafter, the print data of the receipt main body is created and printed as in the above-mentioned embodiment, and then the print data of the store name / logo portion is printed, and a blank feed of a predetermined line is performed to make the receipt main body R4. When X lines have been fed from the last line printing, the cutter unit 5 is operated to cut the receipt paper 1.

As a result, the receipt copy R3 containing the header data H1 and the receipt body R4 not containing the header data are integrated, and the cut line 71 and the tally column are provided between the receipt copy R3 and the receipt body R4. A ticket with 72 printed is issued.

According to this other embodiment, the clerk uses the tally field 7
