Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic cash register capable of issuing lottery cash registers.

[Technical background of the invention and its problems] Conventional electronic cash registers stamp stamps such as "Thank you very much" [Thank you very much for your business] on receipts, but product sales data, J1 data, etc. The numerical value is printed by the printer. Note that the same applies to the 1st edition, although there is no stamp printing.

Therefore, if you try to issue a lottery receipt using a conventional electronic main cash register, you will have to print out the lottery numbers. However, double issuance of lottery numbers is not allowed, so if this were to be done in a region or nationwide, the number of cash registers would be enormous, making it difficult to coordinate between each register, and lottery numbers using printers would be difficult. There is a problem in that it is easy to forge a service number. For this purpose, for example, a method can be considered in which serial numbers for lottery tickets are printed in advance on receipt paper at regular intervals, and the receipt paper is sold by local governments or the government to various businesses. However, in this case, only one lottery number is allowed on one receipt, and the number of data that can be printed on one receipt is limited.
~Positioning of the cut becomes a problem. Another problem is how to position a new receipt paper when it is loaded into the printer, or how to position the receipt paper when a receipt paper that has been removed during registration is reloaded. That is, this is the beginning of the receipt paper, and if this is not done correctly, the printing on the paper may be inadvertent, and there is a risk that data may be printed over the lottery numbers.

[Purpose of the Invention] This invention has been made in view of the above circumstances, and it is a method for making sure that the receipt is always cut in a predetermined position when using receipt paper on which lottery tickets are printed in advance. It is possible to reliably insert one lottery number into each of the cash registers 1 and 2, and to always accurately and accurately locate the beginning of the cash register 1 paper, regardless of whether the paper is a new register paper or a reloaded receipt paper. The purpose is to provide an electronic cash register that is easy to use.

[Summary of the Invention] This invention registers product sales data input into each phase by operating a data input means, displays the product sales data and total data on a display, and prints out the data using a printer. In an electronic cash register that issues cash registers, a number of first detection marks are printed on one side of the paper at approximately constant intervals, and a second detection mark is printed on the other side of the paper, with the second detection mark being printed from the first detection mark. A large number of prints are performed at substantially the same intervals as the first detection marks at positions shifted in the opposite direction to the feed direction of the paper, and numerical values are printed at substantially the same positions in the non-printing area between at least the first detection marks. Receipt paper on which different lottery numbers are printed one by one, a printer for printing product sales data, totals, etc. on the printing area of this receipt paper, and a feed for controlling paper feeding from cash register 1. A printer t1. having a mechanism and a cutter for cutting receipt paper. lil, a first sensor that detects the first detection mark, a second sensor that detects the second detection mark, and a feed mechanism and a cutter in response to the detection operation of the detection mark by the first sensor. Control and checkout
1 - Receipt cut control means that cuts the paper at a predetermined cutting position slightly shifted from the first detection mark in the feed direction of the paper; and a printer that cuts the receipt paper in response to the detection operation of the detection mark by the second sensor. a receipt paper positioning means for positioning the printing start position in the printing area by the printer; a receipt/feed key for feeding the receipt paper; a feed counter that counts the number of feed lines; a line counter that counts the allowable number of print lines of product sales data on receipt paper; printing control means for prohibiting printing of at least the product sales data until the detection mark is detected, and the first sensor detects the first detection mark before the feed counter counts a preset count number. In this case, the operation of the receipt cut control means is prohibited, and the feed counter reaches the set count number by 1.
- When the first sensor detects the first detection mark after the receipt cut, the operation of the receipt cut control means is permitted.

6, the 7M mark 27 as the second detection mark, and the EM mark 29 as the first detection mark. Consisting of an 8-digit serial number that varies according to
9 and are sequentially printed on the front side of paper 18.26. The 7M mark 27 and EM mark 29 are on paper 1.
8. The TM mark 27 is printed on the back side of 26 at approximately constant intervals on each side, and the TM mark 27 is the 2M mark 29
The paper 18, 26 is printed with a shift of several lines in the opposite direction to the feeding direction of the paper 18, which is indicated by a solid arrow in the figure. It should be noted that on the surface of the paper, an explanatory text 30 containing a message related to the lottery is printed at a position shifted by several lines in the feeding direction of the paper from the position of the 2M mark 29.

FIG. 10 is a diagram showing the positional relationship between the receipt paper 18 and each part of the printer mechanism. When the first TM sensor 4)-22 detects the TM mark 27, the stamp printing position S on the receipt paper 18 is The printing position is located 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 located at the cutter 15 position. Note that a serial number N is printed three lines above the date printing position, and a register number R is printed four lines above.

FIG. 11 shows that the CPU 51 is connected to the first EM sensor +1.
-21 and the first TM sensor 22 detecting the 2M mark 29 and 1M mark 27 on the receipt paper 18. This process is performed based on the program data in the ROM 52. Note that this process will be described for the case of receipt paper, but it is the same for journal paper, however, in the case of journal paper, stamp printing and receipt cutting processes are not performed.

In this process, first, it is checked whether or not the receipt paper 18 feed key 39 has been pressed. If the feed key 39 is not pressed manually, then it is checked whether the roll switch 4 to the controller 1 is in the "registration" mode. "
In the "registration" mode, it is next checked whether the registration flag UR has been reset. If the registration flag UR is reset to 1~, the first TM sensor 22
Then, the first EM sensor 21 detects the 1M mark 27 and the EM mark 29. If the 1M mark 27 is detected and the 2M mark 29 is not detected, it is determined that the registers 1 to 18 are correctly set, and the paper lamp of the status indicator 72 is controlled to turn off. Also T
If the M mark 27 is not detected or if both the 1M mark 27 and 2M mark 29 are detected at the same time, it is determined that there is an abnormality on the receipt paper 18, and the paper lamp is blinked. In other words, if the TM mark 27 is not detected, the paper has not been let in correctly, but paper that is not for lottery tickets has been put into the cellar 1. Also, if the 1M mark 27
If both the and E-1 mark 29 are detected at the same time, this is a phenomenon that occurs because no paper is set at all, and it is thereby detected that the C paper is not set. If it is determined that the paper 18 has been correctly loaded into the cash register 1, the machine waits for the key to be manually operated.

Then, if there is key power, a mode check is performed, and if it is in the "registration" mode, it is determined whether the key person is the department key 32, deposit/execution key 35, or some other key power. 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 manually before that key 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 printer 6
1 prints the date data of the hour 81 circuit 66.

Next, feed only one line, and set the registration flag UR.
, clearing the line counter LiC to zero, and setting the sheet number counter PEG to 1 are performed in sequence. Also, if the registration flag UR is set, this process is passed.

Next, it is checked whether the line number counter LiC has cleared 10 lines, which is the allowable number of print lines.

Count 10 lines
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 contents of the line counter LiC. Increase the count by 1.

Then, the program routine returns to the process of detecting the 1M mark 27 and the EM mark 29 again. Also, line number counter L
When the iC has counted 10 lines, the printer 61 prints out the total up to that point as a small cut amount, and after feeding one line, the first E fvl sensor 21 detects the E M mark 29. This is repeated until the EM mark 29 is detected. 2M mark 2 if you recover
The receipt paper 18 will be fed until 9 is detected. Then, when the E IV+ mark 29 is detected, only one line is fed, and then the printing process of the register number stored in the register number memory 533 and the printing process of the serial number N stored in the serial number memory 534 are performed. and then feed only two lines. At this point, the receipt paper 18 (exactly positioned at the position shown in FIG. , and issue the previous register 1 to 0 from the register 1 issue port 5. Also, the sheet number counter PEG is raised by 1 to print the print area on the receipt paper 18 to be issued next. Print the date at the printing start position, then feed only one line, then print the subtotal amount, and press the line number counter L.
Set 1 to IC. Thereafter, in the same manner as described above, the registration process in the departmental sales memory 531, the display of the department code, and the printing process are performed, and the line number counter LiC is counted up. And again 7M mark 27 and 2M mark 2
The program routine returns to the detection process at step 9.

When the above-mentioned key is in the top/cash total key 35, first check whether the registration flag UR has been reset, and if it has been reset, the deposit/cash total key 35 is operated even though it is not being registered. It is determined that this has occurred and handles the error. If it is set, the contents of the line number counter LiC are checked, and if the contents are not 10 lines, feeding control of the receipt paper 18 is performed until the 10 lines are completed. Then, when the line number counter LiC counts 10 lines, the memory processing for deposit and cash total, that is, the total memory for each 532.5
Performs processing such as registering total sales data to 33.534. It also sequentially performs display processing of the total amount, display processing of the change amount, printing processing of the responsible person code and total amount stored in the responsible person code memory 535, and further printing of the time called from the clock reading 66. Next is EM-Mark 2
The receipt paper 18 is fed until 9 is detected by the first EM sensor 21, and when the EM mark is detected, only one line is fed, and then the register number is printed and the serial number memory 534 is stored. After adding 1 to the contents, the serial numbers are printed in sequence. After feeding only two more lines, print the stamp, reset the 7-lag UR while registering the receipt cut, and restart the program routine.TIVI mark 27 and EM mark 29
Return to detection processing.

Further, if there is a key person [j] of the receipt feed key 39 in the first check, the feed counter FC is first reset. Then, unless the feed key is manually pressed and the mark detection is not set to 1, the feed flag FE is set to 1 and the paper register 1 to paper 18 are fed. ) From J run 1 onward, the detection of the 7M mark 27 by the first 7M sensor 22 takes priority over the detection of the E'M mark 29 by the first EM sensor 21. When the 7M mark 27 is detected in this detection process, one line is fed and the feed flag FE is set to 1.Furthermore, the feed counter FC counts up by one and waits for the end of the operation of the feed key 39. When the operation of the feed key 39 is completed, the feed flag FE is reset and the program routine returns to the beginning. Also feed counter FC
If the feed line count exceeds 8 lines, E
The 2M mark 29 is detected by the tvl sensor 21, and the 7M mark 27 is detected by the T~1 sensor 22, and the one detected first is given priority. At this time, the following mark detection processing is performed. That is, E.M.
When two EM marks are detected first by the sensor 21, one line is fed, and then a register number and a serial number are sequentially printed. Subsequently, two lines of feed are performed, then stamp printing and receipt cutting are performed in sequence, and the process waits until the feed key 39 is manually stopped. When the manual input of the feed key 39 is stopped, the feed flag FE is reset and the program routine is returned to the beginning.

Also, when the T fvl mark 27 is detected first by the 1M sensor 22, the J, Ru7
As in the case where priority is given to detecting the M mark 27, only one line is fed, and then the feed flag FE is set to 1~ to specifically search for the manual key stop of the feed key 39. At this time as well, when the 4-man power of the feed key 39 is stopped, the feed flag FE is reset to 1 to return the program routine to the beginning.

Note that when normal receipt paper is loaded or when no paper is loaded, the rotation of the feed couple, ie, the feed roller 16, is controlled as long as there is human power for the three feed keys.

In addition, in this program processing, all printing such as date printing, subtotal printing, register number printing, serial number printing, department code and amount printing, manager code and total amount printing, time stamp printing, etc. are not described in the program routine. is always accompanied by a one-line feed.

In the device according to the embodiment of the present invention configured as described above, when the first EM sensor 21 detects the EM mark 29, it feeds one line, prints a register number, prints a serial number, and feeds two lines. Always in the correct position, i.e. 2
Cut to cash register 1 at a predetermined position slightly in the two-weed direction from M mark 29, and then check cash register 1 to be issued next.
The 7M mark 27 on the paper 18 is the first 1M sensor 22
2M mark 29 and Tfv
! Since the lottery number 111 is stamped between the mark 27 and the mark 27, the length of each issued cash register 1 is equal, and moreover, only one lottery number 28 is always included in the receipt. There is no risk of having two lottery numbers on one receipt. Also, when printing is started manually on the receipt paper 18, the first TM sensor 22 is always pressed.
has detected the 7M mark 27, and the line number counter L
When the iC prints 10 lines, which is the allowable number of lines to be printed, the subsequent keys prohibit manual data printing and start the first EM.
Since the receipt is fed until the sensor 21 detects the 2M 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 exceeds 10 items that fit into one cash register, when the sales data for 10 items is printed on the first receipt, that receipt will be issued, and the 11th receipt will be issued. For subsequent product sales data, please refer to E fvl mark 29 and 7M.
The detection operation of the mark 27 causes it to be printed on the receipt paper to be issued next, so although more than one receipt will be issued to - number of customers, one registration operation will print the item purchased by that customer. The registration process can be performed without any problems. For example, if you sell two products worth 123 yen in department "01" and
5", when you purchase one item for 150Q yen, after printing 3 lines of product sales data, 1746 yen, which is the amount of 1 small sum, is printed, and then the line counter LiC prints 10 lines from 1 to 1.
, and then finally enter the responsible code "2".
``Responsibility'' and ``Total amount N 746 yen'' are printed on the receipt, and a receipt as shown in FIG. 12 is issued. For example, if you sell 4 products worth 200 yen in department "01",
1 item worth 100 yen in category “02”, category “0-2J”
1 item of 500 yen in department "o3", 4 items of 120 yen in department "r04J", 1 item of 1200 yen in department "o6", 1 item of 150 yen in department "o6" for a total of 12 items. When you purchase a product, the product sales data for 10 items is printed in the first cash register 1~, and then the subtotal amount r2,910 yen is printed and the cash register 1~ as shown in Figure 13 (a) is printed. is issued, and the remaining two items are printed on the next cash register 1-, and this cash register 1~ has the same serial number r No. 0124 J and subtotal r 2910 yen as the previously issued receipt. ” will be printed and a receipt as shown in FIG. 13(b) will be issued.

When the feed key 39 is operated again, the feed counter FC counts the amount of feed exceeding 8 lines, and
When the 2M mark 29 is detected first by the M sensor 21, one line of feed, printing of a register number, printing of a serial number, two lines of feeding, and stamp printing are performed in order, and the register 1- is printed. This is done, and receipt feeding is stopped in this state. And then the next receipt is T.
The M sensor 22 has reached the position where the 7M mark 27 is detected. Therefore, for example, when a new receipt paper with a surplus part A is loaded into the printer 61 as shown in FIG. After the data is cut, the data is reliably printed at the printing start position in the printing area by manually pressing the department key 32. Also, when the feed key 39 is pressed manually, the feed counter F'C is 8.
TMt before running the line "J"? When the sensor 22 detects the 7M mark 27, it only feeds 11r and stops feeding the receipt, and then presses the department key 32.
Therefore, as shown in FIG. 14(b), for example, as shown in FIG. 14(b), the T M Even when the printer 61 is reloaded with a receipt that has only a few lines up to the print position of the mark 27, the data will be reliably printed at the print start position in the print area by pressing the department key 32. Whether you are loading a receipt or reloading a receipt that was removed midway through, it is always important to position the beginning of the receipt paper, that is, to position the print position at the print start position in the print area, accurately and at all times. It's easy to do.

[Effect between lights] As detailed above, according to the present invention, when using receipt paper on which lottery tickets are printed in advance, the receipt can always be cut at a predetermined position, making it possible to reliably form a single receipt. To provide an electronic cash register in which one lottery number can be inserted into the register, and the beginning of receipt paper can be accurately and easily retrieved regardless of whether the receipt paper is new or reloaded.
