Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an electronic cash register capable of issuing lottery receipts.

[Conventional technology] For example, in conventional electronic cash registers, characters such as ``account statement'' and ``Thank you for your continued support'' are stamped on the receipt, but numerical values such as product sales data and total data are printed on the printer. It is now printed as follows. Note that the same applies to journals, although there is no stamp printing. Therefore, if you try to issue a lottery receipt using a conventional electronic cash register, you will have to print the lottery number.

[Problem to be solved by the invention] However, since double issuance of lottery numbers is not allowed, if this were to be done regionally or nationally, the number of cash registers used would be enormous, and coordination between each register would be difficult. There is also the problem that lottery numbers are easily forged by printers. For this purpose, for example, a system may be considered in which serial numbers for lottery tickets are printed in advance on receipt paper at regular intervals, and the receipt paper is then sold by local governments or the government to various businesses. However, in this case, since only one lottery number is allowed on one receipt, the number of data that can be printed on one receipt is limited, and positioning of the receipt cut becomes a problem. Another problem is what to do if the number of items purchased by one customer cannot fit on one receipt.

This invention was made in view of the above circumstances, and it is possible to reliably include one lottery number on each receipt when using receipt paper on which lottery numbers are printed in advance, and it is also possible to print the lottery numbers on the receipt paper. To provide an electronic cash register which is free from the risk of overprinting data and which can sufficiently cope with the purchase of more than one customer on a single receipt. .

Another object of the present invention is to provide an electronic cash register in which there is no possibility that the printer will print data while the receipt paper is not set.

A further object of the present invention is to provide an electronic cash register that allows easy confirmation of data between receipts even when two or more receipts are issued to one customer.

Furthermore, the present invention provides an electronic cash register that can easily verify that even if two or more receipts are issued to one customer, each receipt was issued by the same registration operation. With the goal.

[Means for Solving the Problems] The present invention registers product sales data input for each customer by operating a data input means, displays the product sales data and total data on a display, and displays the product sales data and total data on a printer. In electronic cash registers that print out and issue receipts, at least a large number of detection marks are printed vertically at approximately constant intervals, and each of the detection marks is located at approximately the same position and has a different numerical value for lottery tickets. Receipt paper on which numbers are printed one by one; a printer for printing product sales data, totals, etc. on the receipt paper; a feed mechanism for feeding and controlling the receipt paper; and a cutter for cutting the receipt paper. a first and second printer mechanism that detects the detection mark on the receipt paper at different timings;
and a receipt that controls the feed mechanism and the cutter in response to the detection operation of the detection mark by the first sensor and cuts the receipt paper at a predetermined cutting position other than the printing position of the lottery number. a cut control means; a receipt paper positioning means for positioning the receipt paper at a printing start position in the print area of the printer in response to the detection operation of the detection mark by the second sensor; a line number counter that counts the number of printed lines; and a print control means that prohibits printing of the product sales data until the detection mark is detected by the first sensor when the line number counter counts the allowable number of printed lines. It was established.

The present invention also includes a data input prohibiting means for determining that the receipt paper is not set when the first and second sensors perform mark detection operations at the same time, and prohibiting data input from the data input means. This is what I did.

Further, in the present invention, when the line counter counts the permissible number of print lines of the product sales data during registration of the product sales data, at least the total data up to that point is printed, and the first product on the receipt paper to be issued next is printed. A total data printing means is added to print the same total data again at the sales data printing position.

This invention also includes a receipt number printing means that prints the same receipt number as the previous one on the next receipt paper when the line counter counts the allowable number of print lines during product sales data registration. It is.

[Operation] In the present invention having such a configuration, when the first sensor detects the detection mark on the receipt paper at the time of registration, the feed mechanism operates to control the feeding of the receipt paper, and the cutter operates to cut the receipt paper into a lottery ticket. Cut at a predetermined cutting position other than the printed position of the application number.

Further, when the second sensor detects the detection mark on the receipt paper, the receipt paper is positioned at the printing start position in the printing area by the printer. When the product sales data is printed on the receipt paper, the line counter counts the number of printed lines, and when this counted line number reaches the allowable number of printed lines, printing is prohibited after that, and this is determined by the first sensor. This will continue until the detection mark is detected.

Furthermore, in the present invention, when the first and second sensors perform mark detection operations at the same time, it is determined that the phenomenon has occurred because the receipt paper has not been set, and data input from the data input means is stopped. prohibit.

In addition, in the present invention, when the line number counter at the time of registration counts the allowable number of print lines, the total up to that point is printed on the receipt paper, and then printing on the next receipt paper is started, and Also, the same total as the total printed on the previous receipt paper will be printed at the first printing position.

In addition, in the present invention, printing of sales data for which the line number counter counts the allowable number of print lines at the time of registration is transferred from the previous receipt paper to the next receipt paper. The same receipt number will be printed.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

A person-in-charge code memory 535 storing the information is formed.

FIG. 9 shows the lottery number 2 preprinted on the receipt paper 18 and journal paper 26.
8. This is a diagram showing the arrangement relationship between the TM mark 27 and the EM mark 29. The lottery number 28 is composed of, for example, an 8-digit serial number that changes continuously, and is printed in sequence at regular intervals. Also mentioned above
The TM marks 27 are located exactly on the back side of the lottery numbers 28 and are printed on one side of the paper at approximately regular intervals and arranged vertically, and are further aligned with the EM marks 2.
9 are located on the back surface slightly above the printing position of the lottery numbers 28 and are printed vertically on the other side of the paper at approximately constant intervals. In addition,
On the surface of the paper where the EM mark 29 is located, there is an instruction sheet 3 containing messages related to the lottery.
0 is printed.

FIG. 10 is a diagram showing the positional relationship between the receipt paper 18 and each part of the printing mechanism. When the first TM sensor 22 detects the TM mark, the stamp printing position S on the receipt paper 18 is at the stamp 13 position. The date printing position D is one line before the position where the printing drum 11 and the printing hammer 12 face each other, and the leading edge of the receipt paper 18 is at the cutter 15 position. In addition, the date printing position D
A serial number N is printed three lines above, and a register number R is printed four lines above.

FIG. 11 shows that the CPU 51 uses the first EM sensor 21 and the first TM sensor 22 to
This is a flowchart showing the processing when the mark 29 and the TM mark 27 are detected. This processing is performed based on the program data of the ROM 52. Note that this process will be described for the case of receipt paper, but
The same applies to journal paper, except that stamp printing and receipt cutting are not performed on journal paper.

This process first checks whether the control switch 4 is in the "registration" mode.
If it is in the "registration" mode, it is checked whether the next registration flag UR has been reset. And if the registration flag UR is reset, the first
TM sensor 22 and first EM sensor 21
Detection processing of the TM mark 27 and EM mark 29 is performed using the following method. Then, TM mark 27 is detected,
If the EM mark 29 is not detected, it is determined that the receipt paper 18 is correctly set, and the paper lamp of the status indicator 72 is controlled to turn off.

Also, TM mark 27 is not detected,
If both the TM mark 27 and the EM mark 29 are detected at the same time, it is determined that there is an abnormality in the receipt paper 18, and the paper lamp is blinked. (Data input prohibition means) In other words, if the TM mark 27 is not detected, the paper may not be set correctly, or
This is because non-lottery paper has been set. Also, if both the TM mark 27 and EM mark 29 are detected at the same time, this phenomenon occurs because no paper has been set at all. Detected.

If it is determined that the receipt paper 18 is correctly set, the system waits for key input. Then, if there is a key input, a mode check is performed and "Register"
If it is the mode, it is determined whether the key input is the department key 32, deposit/account key 35, or another key input. If it is the department key 32, it is checked whether the number digits entered in the product sales amount data by the number key 31 entered are correct. If this number digit is incorrect, an error will be handled. If it is correct, then it is checked whether the registration flag UR has been reset. If it has been reset, it is determined that this is the first department registration, and the date data of the clock circuit 66 is printed by the printer 61. Next, only one line is fed, and the registering flag UR is set, the line counter LiC is cleared to zero, and the sheet number counter PEG is set to 1. Also, if the registration flag UR is set, this process is passed.

Next, the line number counter LiC is 10, which is the allowable number of print lines.
Check whether rows are being counted or not. Ten
If no rows are counted, departmental sales memory 5
31, displaying the department code and amount on the display 71, printing the department code and amount on the receipt paper 18 using the printer 61, and finally displaying the line number counter LiC. Make the content count up by one. The program routine then returns to the control switch 4 mode check process again. Also, when the line counter LiC counts 10 lines, the total up to that point is printed out as a subtotal amount by the printer 61 (total data printing means), and after feeding one line, the first EM sensor EM by 21
The mark 29 is detected. This is EM mark 29
This is repeated until detected. In other words
Receipt paper 1 until EM mark 29 is detected
8 will be fed. (Print control means) When the EM mark 29 is detected, only one line of feed is performed, and then the register number memory 53
3 and the serial number N stored in the serial number memory 534 (receipt number printing means), and then only two lines of feed are performed. At this point, the receipt paper 18 is positioned exactly as shown in FIG. Then, a stamp 13 is used to print a stamp on a receipt paper 18 to be issued next, a cutter 15 is used to cut the receipt paper 18, and the previous receipt is issued from the receipt issuing port 5. (Receipt cut control means) It also increments the sheet number counter PEG by one, prints the date on the next receipt paper 18 to be issued, and then feeds only one line before printing the subtotal amount (total data printing means)
Set the line number counter LiC to 1. Thereafter, in the same manner as described above, the registration process in the departmental sales memory 531, the display of the department code, the printing process are performed, and the line number counter LiC is counted up. The program routine then returns to checking the mode of the control switch.

When the above-mentioned key input is the deposit/account key 53, it is first checked whether the registration flag UR has been reset, and if it has been reset, it is determined that the deposit/account key 53 has been operated even though registration is not in progress. Make decisions and handle errors. Also, if it is set, the contents of the line number counter LiC are checked and the contents are
If the count has not reached 10 lines, feed control of the receipt paper 18 is performed until 10 lines have been counted. When the line counter LiC counts 10 lines, memory processing for deposits and totals, that is, processing for registering total sales data in the cash sales memory 532, etc. is performed. In addition, the display processing of the total amount, the display processing of the change amount, the printing processing of the responsible person code and the total amount stored in the responsible person code memory 535, and the clock circuit 6
The times called from 6 are sequentially printed.

Next, EM mark 29 is the first EM sensor 2
The receipt paper 18 is fed until the EM mark is detected at 1. When the EM mark is detected, only one line of feed is performed, and then the register number is printed, and the contents of the serial number memory 534 are incremented by 1, and then the series is Print the numbers sequentially. Furthermore, after performing only two lines of feed, stamp printing and receipt cutting are performed in sequence (receipt cutting control means).Finally, the registration flag UR is reset, and the program routine returns to the control switch 4 check processing.

In addition, in this program processing, date printing,
Subtotal amount printing, register number printing, serial number printing,
All printing, such as department code and amount printing, manager code and total amount printing, time stamp printing, etc., is always 1.
This is done with a line feed.

In the device according to the embodiment of the present invention configured as described above, the first EM sensor 21 is connected to the EM mark 29.
When detected, it prints one line of feed, prints the register number, prints the serial number, and feeds two lines, then cuts the receipt at a position other than the print position of lottery number 28, and then prints the next sheet of paper to be issued. Since the 18 TM mark 27 is now detected by the first TM sensor 22, and the lottery number is printed at the same position as the TM mark 27,
Each issued receipt always contains only one lottery number 28, and there is no possibility that two lottery numbers 28 may be contained on one receipt. In addition, when printing is started on the receipt paper 18 by key input, the first TM sensor 22 always detects the TM mark 27, and when the line counter LiC counts 10 lines, which is the allowable number of print lines, Since data printing by key input is prohibited and the receipt is fed until the first EM sensor 21 detects the EM mark 29, there is no risk of data being erroneously printed over the lottery number. Furthermore, even if the number of purchased items by one customer is 10 or more that can fit on one receipt, the receipt will be issued as soon as the product sales data for 10 items is printed on the first receipt, and the sales of the 11th and subsequent items will be issued. About the data
The detection operation of the EM mark 29 and TM mark 27 will print them on the next receipt paper to be issued, so two or more receipts will be issued to one customer, but one registration operation will print them on the receipt paper to be issued next. Then, the registration process for the customer's purchased products is carried out without any problems. For example, 2 items priced at 123 yen in department "01",
When you purchase one item worth 1,500 yen in department "05", print out the subtotal amount after printing 3 lines of product sales data.
1,746 yen is printed, and then feed is performed until the line counter LiC counts 10 lines.Finally, the responsible person code ``2 Responsibility'' and the total amount ``1,746 yen'' are printed and the receipt is cut.Figure 12 A receipt as shown in will be issued. For example, department "01"
4 items worth 200 yen in category ``02'', 1 item worth 100 yen in category ``02'', 1 item worth 500 yen in category ``03'', 4 items worth 120 yen in category ``03'', 4 items worth 120 yen in category ``02'' When you purchase a total of 12 items, one item worth 1,200 yen in category ``04'' and one item worth 150 yen in category ``06,'' print the product sales data for 10 items on the first receipt. The subtotal amount "2910 yen" will be printed on the receipt as shown in Figure 13 a, and the remaining two items will be printed on the next receipt, and this receipt will contain the previously issued receipt. The same serial number ``No. 0124'' and the subtotal amount ``2910 yen'' are printed, and a receipt as shown in Figure 13b is issued.

In addition, when the receipt paper 18 is not set, the first EM sensor 21 and the TM sensor 22
At the same time, the EM mark and TM mark are detected.This causes the paper lamp to blink to notify that an abnormality has occurred in the paper, and also prohibits key input judgment, so that the receipt paper 18 can be left unset. There is no possibility that the printer 61 will print data. Furthermore, if one customer purchases 10 or more items, the product sales data for 10 items is printed on the first receipt, and the total value of those 10 items is printed on that receipt as the subtotal amount, and then the sales data for the 10 items is printed on the receipt. Same as the subtotal amount printed at the end of the previously issued receipt on the first line where the first product sales data is printed before printing the product sales data from number 11 on the next receipt. Since the subtotal amount is printed, even if two or more receipts are issued to one customer, the data between each receipt can be easily confirmed using the subtotal amount. Furthermore, when two or more receipts are issued to one customer, the same serial number is printed on each receipt without counting up the contents of the serial number memory 534. Therefore, it is easy to check whether each receipt was issued by the same registration operation.

In addition, in the above embodiment, the EM sensor and
Although we have described a method in which the TM sensor is installed at the same position and thereby detects the EM mark and TM mark at different positions to control the timing of receipt cutting and the positioning of the data printing start position, this is not necessarily limited to this. However, even if the EM sensor and TM sensor are placed on the same vertical line at different positions and both sensors detect one mark, the mark detection timing may be shifted. The same control can be achieved.

[Effects of the Invention] As detailed above, according to the present invention, when using receipt paper on which a lottery ticket is printed in advance, it is possible to reliably include one lottery number on each receipt, and it is also possible to It is possible to provide an electronic cash register which is free from the risk of overprinting print data on the number and which can sufficiently handle even if the number of items purchased by one customer is more than can fit on one receipt. be.

Further, according to the present invention, it is possible to provide an electronic cash register in which there is no possibility that the printer will print data while the receipt paper is not set.

Further, according to the present invention, it is possible to provide an electronic cash register that allows easy confirmation of data between receipts even when two or more receipts are issued to one customer.

Furthermore, the present invention provides an electronic cash register that can easily verify that even if two or more receipts are issued to one customer, each receipt was issued by the same registration operation. It is possible.
