Description

[Detailed Description of the Invention] [Industrial Application Field] This invention involves printing consecutive numbers such as lottery numbers at regular intervals on paper such as receipts or journals, and printing them on the paper. The present invention relates to an electronic cash register that prints product sales data registered in the electronic cash register.

[Conventional technology] In conventional electronic cash registers, for example, characters such as "account statement" and "thank you for your continued support" are printed in the stamp on the receipt, but numerical values such as product sales data and total data are printed by a printer. It is now possible to do so. Note that the same applies to journals, although there is no stamp printing.

Thus, for example, if a conventional electronic cash register is used to issue a receipt containing a lottery number, the lottery number will also be printed.

However, lottery numbers are not allowed to be issued twice, so if this were to be implemented regionally or nationally, the number of cash registers would be enormous, making coordination between the registers difficult. There is also the problem that lottery numbers can be easily forged using printers.

For this purpose, for example, a system can be considered in which lottery numbers 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.

[Problem to be solved by the invention] However, even with this method, if the receipt jams for some reason, the receipt will not be fed correctly, and as a result, data will be printed on the printed lottery ticket. Inconveniences occur, such as overprinting or the data itself being overprinted, making the lottery receipt unreliable. There was also a risk that the printer would be damaged.

This invention was made in view of the above circumstances, and in printers that print product sales data using paper on which lottery numbers, etc. are printed in advance, accidents have occurred where the paper gets jammed during feeding. To provide an electronic cash register which can sometimes prohibit the next registration process until a paper jam is cleared, prevent double printing, and prevent damage to a printer.

[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 device, and displays the product sales data and total data on a display device. In electronic cash registers that are printed out on paper, at least a large number of detection marks are arranged vertically at approximately regular intervals in the center column, and each detection mark is located at approximately the same position between the detection marks and has a different numerical value, such as a lottery number. A sheet of paper on which consecutive numbers are printed one by one, a sensor that detects a detection mark on this sheet of paper, and a sheet of paper that positions the sheet of paper at the printing start position in the printing area by the printer in response to the detection operation of the detection mark by this sensor. A positioning means, a mark detection flag that is set in response to the first product sales data registration operation after the sensor detects the mark, and is reset when the sensor no longer detects the mark, and a paper positioning means that positions the paper. The mark detection flag is set even if the paper is positioned by the paper positioning means. A registration system is provided for prohibiting the registration process of product sales data and the printing of product sales data on the paper if the product sales data is registered.

Further, the present invention is provided with means for canceling the prohibition of registration processing and printing when the mark detection flag is reset in a state where registration processing and printing are prohibited and held by the registration shrine control means.

[Operation] In the present invention having such a configuration, when the mark printed on the paper is detected by the sensor, the paper is fed and the printer is set at the printing start position in the printing area. Then, the mark detection flag is set by the first registration operation of product sales data after the mark is detected by the sensor, and then when the paper is fed and the sensor goes out of the mark detection state, the mark detection flag is reset.

However, if the mark detection flag remains set even after the next paper is fed for positioning, it is determined that a paper jam has occurred, and the product sales data registration process and printing on the paper are prohibited. .

Further, even if registration processing and printing are prohibited and held in a paper jam state, the prohibited state can be canceled if, for example, the position of the paper is corrected and the mark detection flag is reset.

A responsible person code memory 535 and the like are formed. FIG. 9 is a diagram showing the arrangement relationship of lottery numbers 28, 1M marks 27 and 6M marks 29 printed in advance on the receipt paper 18 and journal paper 26, and the lottery numbers 28 change continuously, for example. It consists of an 8-digit serial number and is printed sequentially at regular intervals. Also, the 7M mark 27 is exactly the lottery number @2.
The EM mark 29 is located on the back side of the paper and is printed vertically at approximately regular intervals on one side of the paper, and the EM mark 29 is located on the back surface slightly above the printing position of the lottery number 28. are printed vertically on the other side at approximately regular intervals. Note that an explanation 130 containing messages related to the lottery is printed on the surface of the paper where the two EM marks are located.

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 22 detects the 7M mark 27, the stamp printing position S on the receipt paper 18 is changed to the meta 2 frame. 13 position, and the date printing position is located between the printing drum 11 and the printing hammer 1.

．． 24 and 1M sensors 22 and 25 respectively when the EM mark 29 and the 1M mark 27 are detected. This processing is performed based on the program data of the ROM 52.

In this process, first, it is checked whether the control switch 4 is in the "registration" mode.

If it is in the "registration" mode, then it is checked whether the registration flag UR has been reset. And if the registration flag UR is reset, each 1M sensor 22.2
5 and each EM sensor 21. 1M mark 27 by 24
and detecting the 6M mark 29. If the 1M mark 27 is detected on both the receipt paper 18 and the journal paper 26, and the 6M mark 29 is not detected, and both the receipt mark detection flag FR and the journal mark detection flag FJ are reset, then the receipt paper 18
Then, it is determined that the journal paper 26 is correctly set, and the paper lamp of the status display 72 is turned off hlWJ. Further, the 1M mark 27 may not be detected on either the receipt paper 18 or the journal paper 26, or even if the 1M mark 27 is detected, the 6M mark 29 may not be detected on either the receipt paper 18 or the journal paper 26.
is detected, or even if the 1M mark 27 is detected and the 6M mark 29 is not detected, either the receipt mark detection flag FR or the journal mark detection flag FJ may be set. 18 or the journal paper 26 is judged to have an abnormality, and the paper lamp is blinked. That is, 1M mark 27
If it is not detected, either the paper is not set correctly or the paper is not for lottery tickets.
Further, if both the 1M mark 27 and the 6M mark 29 are detected at the same time, this is a phenomenon that occurs because no paper is set at all, and it is detected that no paper is set. Furthermore, the fact that the receipt mark detection flag FR and the journal mark detection flag FJ are set means that the receipt and journal have not been fed at all since the previous mark detection, which means that paper clumping is detected. . Further, if either the receipt mark detection flag FR or the journal mark detection flag FJ is set, the receipt feed key 39
, enables operation of the journal sending key 40, and when that key is operated, sending key processing to be described later is performed.

Furthermore, when the TM mark is no longer detected on the receipt paper 18 while the registration flag UR is set, the receipt mark detection flag FR is reset, and the journal paper 2
When the TM mark 6 is no longer detected, the journal detection flag FJ is reset and the paper lamp is controlled to turn off.

If it is determined that the receipt paper 18 is correctly set, the key is placed on standby. and the feed key 39.
If there is an operation of 40, forward key processing is performed. Also, if the key is not a feed key, the department key 32 or the deposit/cash key 3
5 or other key personnel. If it is the department key 32, it is checked whether or not the numeric entry of the product sales amount data using the numeric key 31 entered manually before that key is correct. If this arithmetic is incorrect, handle an error. 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 from the clock circuit 66 is printed by the printer 61.

Next, feed only one line, and set the registration flag UR.
, clear the line counter LINECTR to zero,
The sheet number counter PAGECTR is sequentially set to 1. Roughly sets the receipt mark detection flag FR and journal mark detection flag FJ. On the other hand, if the registration flag UR is set, this process is passed.

Next, it is checked whether the line number counter LINECTR is counting 10 lines, which is the allowable number of print lines. 10
If the rows are not counted, the process of registering the product sales data in the departmental sales memory 531, the process of displaying the department code and amount on the display 71, and the process of printing the department code and amount on the receipt paper 18 by the printer 61 are performed. This is performed sequentially, and finally the contents of the line counter LINECTR are incremented by one. And again 7M mark 27 and E
The program routine returns to the M mark 29 detection process.

Also, when the line number counter LINECTR counts 10 lines, the printer 61 prints the total up to that point as a subtotal amount, feeds one line, and then presses the 2M sensor 21.
．． 24 to detect the EM mark 29. This is EM
This process is repeated until the mark 29 is detected. In other words, the receipt paper 18 until the EM mark 29 is detected.
and journal paper 26 will be fed.

When the EM mark 29 is detected, only one line is fed, and then the register number stored in the register number memory 533 is printed and the serial number memory 53
The serial number N stored in 4 is printed, and then only two lines are fed. At this point, the receipt paper 18 is positioned exactly as shown in FIG.

Then, the stamp 13 prints a stamp on the receipt paper 18 to be issued next, the cutter 15 cuts the receipt paper 18, and the previous receipt is issued from the receipt issuing port 5.

Note that this stamp printing and paper cutting are not performed on the journal paper 26. Next, the number counter PA
GECTR is counted up by one, the date is printed on the receipt paper 18 and journal paper 26 to be issued next, and after feeding only one line, the subtotal amount is printed and 1 is added to the line number counter LINECTR. set.

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 LINECTR is counted up. The program routine then returns to the process of detecting the 7M mark 27 and EM mark 29 again.

When the above-mentioned key is the deposit/account key 35, first check whether the registration flag LIR has been reset, and if it has been reset, it is determined that the deposit/account key 35 has been operated even though registration is not in progress. Make a judgment and handle the error. Also, if it is set, the line number counter LINECTR
If the content is not 10 lines, feeding control of the receipt paper 18 and journal paper 26 is performed until 10 lines are counted. Then, when the line number counter LINECTR counts 10 lines, memory processing for deposits and totals, that is, processing for registering sales total data in the cash sales memory 532, etc. is performed. 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 printing of the time called from the clock circuit 66. Next, the EM mark 29 is the 2M sensor 21.
The receipt paper 18 is fed until the EM mark is detected at 24, and when the EM mark is detected, only one line is fed, then the register number is printed, and the contents of the series number memory 534 are incremented by 1, and then the series is fed. Print the numbers sequentially. Further, only two lines are fed, and then stamp printing and receipt cutting are performed in sequence.Finally, the registration flag UR is reset and the program routine returns to the process of detecting the 7M mark 27 and 5M mark 29. In this case as well, in the case of the journal paper 26, stamp printing and paper cutting are not performed.

In addition, in this program processing, all printing such as date printing, subtotal nod printing, register number printing, serial number printing, department code and amount printing, manager code and total amount printing, and time stamp printing are always accompanied by a one-line feed. It is something that is done.

The processing of the feed keys 39 and 40 is performed as shown in FIG. For example, regarding the receipt feed key 39, first the feed counter FCTR is reset, and if there is no paper jam, the receipt mark detection flag FR is reset. As long as the manual input of the feed key 39 is maintained and no mark is detected, the feed flag FF is set and the receipt paper 18 is fed. The detection of the 7M mark 27 by the TM sensor 22 takes priority over the detection of the 5M mark 29 by the 6M sensor 21 until the feed counter FCTR counts the number of feed lines of 8. When the 7M mark 27 is detected in this detection process, one line is fed, the feed flag FF is set, and the feed counter FCTR 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 FF is reset and the program routine returns to the beginning.

In addition, when the feed line count of the feed counter FCTR exceeds 8 lines, the 5M mark 29 is detected by the 6M sensor 21.
and the 7M mark 27 by the TM sensor 22, and the one detected first is given priority. At this time, the following mark detection processing is performed. That is, when the 5M mark 29 is detected first by the 6M sensor 21, one line is fed, and then the register number and the serial number are sequentially printed. Next, 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 FF is reset and the program routine is returned to the beginning. Also T
When the 7M mark 27 is detected first by the M sensor 22, as in the case where the 7M mark 27 is detected first by the TM sensor 22, only one line is fed, and then the feed flag FF is set and the feed key 39 is pressed. Wait for the key to stop manually. At this time as well, the feed key 39
When key power is stopped, the feed flag FF is reset and the program routine is returned to the beginning. Incidentally, when normal receipt paper is loaded or when no receipt paper is loaded, the rotation of the feed mechanism, that is, the feed roller 16 is controlled as long as the key force of the feed key 39 is present.

In the apparatus according to the embodiment of the present invention configured as described above, 6

Two lines of feed are performed and the receipt is cut, but the journal paper 26 is not cut at this time. ), then the 7M mark 2 on the receipt paper 18 to be issued next.
7 is now detected by TM sensor 22.25,
In addition, the lottery number is printed in the same position as the 7M mark 27, so each receipt issued always has 1.
Only one lottery number 28 is included, and there is no risk of two lottery numbers appearing on a single receipt. Furthermore, when printing is started manually on the receipt paper 18 and the journal paper 26, the TM sensor 22.25 always detects the M mark 27, and the line counter LINECTR always detects the M mark 27.
When 10 lines, which is the allowable number of lines to be printed, is counted, subsequent key data printing is prohibited and the 6M sensor 21
．． Since the receipt is fed until the 5M mark 29 is detected at 24, there is no risk of data being erroneously printed over the lottery number.

In addition, when the sales data for 10 items is printed on the first receipt for at least 10 items purchased by a customer that fit on a single receipt, that receipt will be issued, and for the 11th and subsequent items. Sales data is printed on the next receipt paper to be issued by the detection of the EM mark 29 and TM mark 27, so two or more receipts will be issued to - customers, but only once. With this registration operation, the customer can register the purchased products without any trouble.

Also, when the receipt paper 18 or the journal paper 26 is not set, the 6M sensor 21, 24 and the TM
The sensors 22 and 25 will simultaneously detect the EM mark and the 7M mark, and this will cause the paper lamp to blink to notify that an abnormality has occurred in the paper, and prohibit key manual judgment, so the receipt paper 18 and There is no risk that the printer 61 will print data without the journal paper 26 being set.

By the way, if an accident occurs in which the receipt paper 18 or the journal paper 26 jams in this device, the receipt mark detection flag FR and the journal mark detection flag FJ are set at the start of the previous registration, and the TM sensor 22 .25 is TM mark 27
Since the paper jam continues to be detected, the paper lamp blinks to notify you of the paper jam. As a result, the user knows that the paper is jammed and can reset the paper.

Moreover, in this case, manual input of the keys is prohibited until the paper jam is cleared, so that no product sales data is registered or printed at all. Therefore, damage to the printer due to overprinting or operation of the printer with paper jams can be prevented.

Also, if there is a paper jam, for example, you can correct the position of the paper and
By removing the mark 27 from detection, key manual input for registration is permitted. In this way, the state in which registration and printing are prohibited due to a paper jam can be easily canceled.

In this embodiment, the 2M sensor and the 1M sensor are provided at the same position, thereby detecting the EM mark and 7M mark at different positions to control the timing of receipt cutting and the positioning of the data printing start position. Although the above description is not limited to this, even if a 2M sensor and a 1M sensor are provided at different positions on the same vertical line, and one mark is detected by both sensors, the mark cannot be detected. The detection timing can be shifted and the same control can be performed.

[Effects of the Invention] As detailed above, according to the present invention, when an accident such as a paper jam occurs during feeding, the next registration process can be prohibited until the paper jam is cleared, and overlapping printing can be prevented. Furthermore, it is possible to provide an electronic cash register that can prevent damage to the printer.

Further, according to the present invention, it is possible to provide an electronic cash register that is easy to handle and can easily cancel the prohibition of registration processing and printing due to a paper jam.

Detailed Description of the Invention and Field of Industrial Application] This invention involves printing consecutive numbers, such as lottery numbers, on paper such as receipts or journals at regular intervals in advance, and registering them on the paper. This invention relates to an electronic cash register that prints product sales data. [Conventional technology] Conventional electronic cash registers, for example, print stamps on receipts such as ``account statement'' and ``every time you have it or do it.'' However, numerical values such as product sales data and total data are printed by the printer. Note that the same applies to journals, although there is no stamp printing. Therefore, for example, if you try to issue a receipt with a lottery number on it using a conventional electronic cash register, the lottery number will also be printed. However, since lottery numbers are not allowed to be issued twice, if this were to be implemented regionally or nationally, the number of cash registers would be enormous, making coordination between each register difficult. For this reason, for example, lottery numbers are printed on receipt paper at regular intervals, and the receipt paper is sold by local governments and governments to various businesses. [Problem to be solved by the invention] However, even with this method, if a paper jam occurs for some reason, the receipt will not be fed correctly, and as a result, the printed lottery ticket will be Inconveniences occur, such as the data being overprinted on the paper, or the data itself being overprinted, making the lottery receipt unreliable.Also, there is a risk that the printer may be damaged. This was done in consideration of this situation, and in cases where product sales data is printed using paper on which lottery numbers, etc. are printed in advance, if an accident such as paper jamming occurs during feeding, paper jams can occur. It is an object of the present invention to provide an electronic cash register that can prohibit the next registration process until the registration process is canceled, can prevent overprinting, and can prevent damage to the printer. [Means for Solving the Problems] This invention The electronic cash register 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 prints out the data on paper using a printer, at least A sheet of paper on which a large number of detection marks are printed vertically arranged at substantially constant intervals, and successive numbers such as lottery numbers, etc., each having a different numerical value are printed one by one located at substantially the same position between the detection marks; A sensor that detects the detection mark on the paper, a paper positioning means that responds to the detection mark detection operation by this sensor and positions the paper at the printing start position in the printing area of the printer, and the first product after the mark is detected by the sensor. The mark detection flag is set in response to the sales data registration operation and is reset when the sensor no longer detects the mark, and the mark detection flag is set when the paper is positioned by the paper positioning means and the mark detection flag is reset. If the registration process of sales data and the printing of product sales data on the paper are permitted, and the mark detection flag is set even if the paper is positioned by the paper positioning means, the registration process of product sales data and the printing of the product sales data on the paper are permitted. and registration control means for prohibiting and maintaining printing of product sales data. Further, the present invention is provided with means for canceling the prohibition of registration processing and printing when the mark detection flag is reset in a state where registration processing and printing are prohibited and held by the registration control means. [Operation] In the present invention having such a configuration, when the mark printed on the paper is detected by the sensor, the paper is fed and the printer is set at the printing start position in the printing area. Then, the mark detection flag is set by the first registration operation of product sales data after the mark is detected by the sensor, and then when the paper is fed and the sensor goes out of the mark detection state, the mark detection flag is reset. However, if the mark detection flag remains set even after the next paper is fed for positioning, it is determined that a paper jam has occurred, and the product sales data registration process and printing on the paper are prohibited. . Furthermore, even if registration processing and printing are prohibited and held in a paper jam state, the prohibited state can be canceled if, for example, the position of the paper is corrected and the mark detection flag is reset.

A person-in-charge code memory 535 storing the information is formed. FIG. 9 is a diagram showing the arrangement relationship of lottery numbers 28.7M marks 27 and EM marks 29 that are preprinted on the receipt paper 18 and journal paper 26, and the lottery numbers 28 change continuously, for example. It consists of an 8-digit serial number printed sequentially at regular intervals. Also, the 7M mark 27 is exactly the room lottery number 28.
The two EM marks are located on the back side of the paper and are printed vertically at approximately constant intervals on one side of the paper, and the two EM marks are located on the back side slightly above the printing position of the room lottery number 28. They are printed vertically on the other side of the paper at approximately constant intervals. Furthermore, on the surface of the paper where the EM mark 29 is located, an instruction manual 3o is printed that includes messages related to the lottery. FIG. 10 is a diagram showing the positional relationship between the receipt paper 18 and each part of the printer mechanism. When the first 7M sensor 22 detects the 7M mark 27, the stamp printing position Is on the receipt paper 18 is at the stamp 13 position. and the date printing position is between the printing drum 11 and the printing hammer 1.

The tip of the cutter 8 is 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 controls each of the 2M sensors 21.
24 and each 7M sensor 22.25 with the EM mark 2
This is a flowchart showing the processing when the 9 and 7M marks 27 are detected, and this processing is performed based on the program data of the ROM 52. In this process, first, it is checked whether the control switch 4 is in the [registration J mode]. If it is in the "registration" mode, then it is checked whether the registration flag UR has been reset. And if the registration flag UR is reset, each 7M sensor 22.2
5 and 7M mark 27 by each 2M sensor 21.24
and detects the EM mark 29. If the 7M mark 27 is detected on both the receipt paper 18 and the journal paper 26, and the 2M mark 29 is not detected, and both the receipt mark detection flag FR and the journal mark detection flag FJ are reset, then the receipt paper 18
Then, it is determined that the journal paper 26 is correctly set, and the paper lamp of the status indicator 72 is controlled to turn off. In addition, the 7M mark 27 may not be detected on either the receipt paper 18 or the journal paper 26, or the 7M mark 27 may not be detected on either the receipt paper 18 or the journal paper 26.
Even if the M mark 27 is detected, the 2M mark 29 may be detected on either the receipt paper 18 or the journal paper 26, or even if the 7M mark 27 is detected and the 2M mark 29 is not detected. If either the receipt mark detection flag FR or the journal mark detection flag FJ is set, it is determined that there is an abnormality in the receipt paper 18 or the journal paper 26, and the paper lamp is blinked. In other words, if the 7M mark 27 is not detected, the paper may not be set correctly, or
This is because paper other than lottery paper is set. Also, if both the 7M mark 27 and 2M mark 29 are detected at the same time, this is a phenomenon that occurs because no paper is set at all. ing. Furthermore, the fact that the receipt mark detection flag FR and the journal mark detection flag FJ are set means that no receipt or journal has been fed since the previous mark detection, and a paper jam is detected. In addition, the receipt mark detection flag F
R and journal mark detection flag FJ (\If either is set, the receipt feed key 39,
The journal sending key 40 is enabled to be operated, and when the key is operated, sending key processing to be described later is performed. Furthermore, when the TM mark is no longer detected on the receipt paper 18 while the registration flag UR is set, the receipt mark detection flag FR is reset, and the journal paper 2
When the TM mark 6 is no longer detected, the journal detection flag FJ is reset and the paper lamp is controlled to turn off. If it is determined that the receipt paper 18 is correctly set, the key is placed on standby. and the feed key 39.
If there is an operation of 40, forward key processing is performed. Also, if the key is not a feed key, the department key 32 or the deposit/cash key 3
5 or other key personnel. If it is the department key 32, it is checked whether or not the numeric entry of the product sales amount data using the numeric key 31 entered manually before that key is correct. If this arithmetic is incorrect, handle an error. 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 from the clock circuit 66 is printed by the printer 61. Next, feed only one line, and set the registration flag UR.
, clear the line counter LINECTR to zero,
The sheet number counter PAGECTR is sequentially set to 1. Furthermore, a receipt mark detection flag FR and a journal mark detection flag FJ are set. On the other hand, if the registration flag tJR is set, this process is passed. Next, it is checked whether the line number counter LINECTR is counting 10 lines, which is the allowable number of print lines. 10
If the rows are not counted, the process of registering the product sales data in the departmental sales memory 531, the process of displaying the department code and amount on the display 71, and the process of printing the department code and amount on the receipt paper 18 by the printer 61 are performed. This is performed sequentially, and finally the contents of the line counter LINECTR are incremented by one. And again 7M mark 27 and 2
The program routine returns to the M mark 29 detection process. When the line counter LINECTR counts 10 lines, the printer 61 prints out the total up to that point as a subtotal amount, then clears the feed counter FCTR, feeds one line, and then prints out the total up to that point as a subtotal amount. E
Detects the M mark. This is continued until the feed counter FCTR counts 22 lines unless the 2M mark 29 is detected. In other words, if the 2M mark 29 is detected before the feed counter FCTR counts 22 lines, this process ends, and even if the 2M mark 29 is not detected, this process ends when the 22 line feed process ends. It turns out. When this process is completed, 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 and only feeds two lines. At this point, the receipt paper 18 is positioned exactly at the position shown at No. 10@. Then, the stamp 13 is used to print a stamp on the receipt paper 18 to be issued next,
A receipt paper 18 is cut by a cutter 15 and the previous receipt is issued from a receipt issuing port 5. In addition,
This stamp printing and paper cutting are not performed on the journal paper 26. Next, the number of sheets counter PAGEC
Count up TR by one, print the date on the receipt paper 18 and journal paper 26 to be issued next, feed only one line, print the subtotal, and set 1 to the line counter LINECTR. set. 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 LINECTR is counted up. The program routine then returns to the process of detecting the 7M mark 27 and EM mark 29 again. When the above-mentioned key is the deposit/cash total key 35, it is first checked whether or not the registration flag UR has been reset, and if it has been reset, it is determined that the deposit/cash total key 35 has been operated even though it is not being registered. Make decisions and handle errors. If it is set, the contents of the line counter LINECTR are checked, and if the contents are not 10 lines, feeding control of the receipt paper 18 and journal paper 26 is performed until 10 lines are counted. and line counter LI
When NECTR 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. 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 printing of the time called from the clock circuit 66. Subsequently, the feed counter FCTR is cleared, one line is fed, and then the EM mark is detected by the EM sensors 21 and 24. This is continued until the feed counter FCTR counts 22 lines unless the EM mark 29 is detected. In other words, if the EM mark is detected before the feed counter FCTR counts 22 lines, this process ends, and even if the EM mark 29 is not detected, 22
This process ends when the row feed process ends. When this process is completed, only one line is fed, then the register number is printed, and the contents of the serial number memory 534 are incremented by 1, and then the serial number is sequentially printed. Further, only two lines are fed, and then stamp printing and receipt cutting are performed in sequence.Finally, the registration flag UR is reset and the program routine returns to the process of detecting the 7M mark 27 and EM mark 29. In this case as well, in the case of the journal paper 26, stamp printing and paper cutting are not performed. 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, responsible person code and total amount printing, and time stamp printing are always accompanied by a one-line feed. It is something that is done. The processing of the feed keys 39 and 40 is performed as shown in FIG. For example, regarding the receipt feed key 39, first the feed counter FCTR is reset, and if there is no paper jam, the receipt mark detection flag FR is reset. As long as the manual input of the feed key 39 is maintained and no mark is detected, the feed flag FF is set and the receipt paper 18 is fed. Then, the detection of the 7M mark 27 by the TM sensor 22 takes precedence over the detection of the EM mark 29 by the EM sensor 21 until the feed counter FCTR counts the number of feed lines of 8. When the 7M mark 27 is detected in this detection process, one line is fed, the feed flag FF is set, and the feed counter FCTR counts up by one and waits for the end of the operation of the feed key 39. When the operation of the feed rekey 39 is completed, the feed flag FF is reset and the program routine returns to the beginning. Also, when the feed line count of the feed counter FCTR exceeds 8 lines, the EM mark 29 is detected by the EM sensor 21.
and the 7M mark 27 by the 7M sensor 22, and the one detected first is given priority. At this time, the following mark detection processing is performed. That is, when the EM mark 29 is first detected by the EM sensor 21, the register number is printed, one line is fed, and then the serial number is printed in sequence. Next, 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 FF is reset and the program routine is returned to the beginning. Also, if the 7M mark 27 is detected first by the 7M sensor 22, just like when the 7M mark 27 is detected by the 7M sensor 22 as described above, only one line is fed, and then the feed flag FF is set and the feed key 39 is pressed. The key is to wait for human power to stop. At this time as well, when the manual input of the feed key 39 is stopped, the feed flag FF is reset and the program routine is returned to the beginning. Incidentally, when normal receipt paper is loaded or when no receipt paper is loaded, the rotation of the feed mechanism, that is, the feed roller 16 is controlled as long as the key force of the feed key 39 is maintained. In the apparatus according to the embodiment of the present invention configured as described above, E
1 when M sensor 21.24 detects EM mark 29
Feed line, print register number, print sequence number,
Two lines of feed are performed and the receipt is cut, but the journal paper 26 is not cut at this time. ), then the 7M mark 2 on the receipt paper 18 to be issued next.
7 is now detected by 7M sensor 22.25,
In addition, the lottery number is printed in the same position as the 7M mark 27, so each receipt issued always has 1.
Only one lottery number 28 is included, and there is no risk of two lottery numbers appearing on a single receipt. Furthermore, when printing is started manually on the receipt paper 18 and the journal paper 26, the 7M sensor 22.25 always detects the 7M mark 27, and the line number counter LINECTR always detects the 7M mark 27.
When the EM sensor 21 counts 10 lines, which is the permissible number of lines to be printed, the EM sensor 21 prohibits the subsequent manual data printing.
．． Since the receipt is fed until the EM mark 29 is detected at step 24, 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 receipt will be issued from the 11th onwards. Product sales data is printed on the receipt paper to be issued next by the detection operation of the EM mark 29 and 7M mark 27, so more than one receipt will be issued to - number of customers. By repeating the registration operation once, the registration process for the customer's purchased products can be performed without any trouble. Also, when the receipt paper 18 or journal paper 26 is not set, the EM sensors 21, 24 and 7M
The sensors 22 and 25 simultaneously perform the operation of detecting the EM mark and TM mark, which causes the paper lamp to blink to notify that an abnormality has occurred in the paper, and prohibits key manual judgment. There is no risk that the printer 61 will print data without the journal paper 26 being set. By the way, if an accident occurs in which the receipt paper 18 or the journal paper 26 jams in this device, the receipt mark detection flag FR and the journal mark detection flag FJ are set at the start of the previous registration, and the 7M sensor 22. 25 is 7M mark 27
Since the paper jam continues to be detected, the paper lamp blinks to notify you of the paper jam. As a result, the user knows that the paper is jammed and can reset the paper. Moreover, in this case, manual input of the keys is prohibited until the paper jam is cleared, so that no product sales data is registered or printed at all. Therefore, damage to the printer due to overprinting or operation of the printer with paper jams can be prevented. Further, if the receipt feed key 39 is operated, for example, in a paper jam state, only this key is accepted and the feed key process is performed. In this process, the receipt paper 18
TM when the paper jam is cleared by forced feeding.
Since the mark 27 is no longer detected, the receipt mark detection flag FR is reset. However, after that, eight lines of feed are performed, and the TM mark is detected again.
Further, when the EM mark 29 is detected, printing of a register number, printing of a serial number, printing of a stamp, and cutting of the receipt are performed in sequence, and the machine waits for the next registration process. In other words, registration is now permitted. Of course, even at this time, if the receipt paper 18 is not fed by the feed key 39 and the TM mark 27 continues to be detected, the receipt mark detection flag FR will not be reset and registration will continue to be prohibited forever. By operating the feed key 39 in this manner, a paper jam can be easily cleared. Note that this operation is similarly performed when the journal feed key 40 is operated as a feed key. However, at this time there will be no stamp printing or receipt cutting. In this embodiment, the EM sensor and the 7M sensor are provided at the same position, thereby detecting the EM mark and the 7M mark at different positions to control the timing of receipt cutting and the positioning of the data printing start position. Although the above description is not limited to this, even if the EM sensor and the 7M sensor are placed on the same vertical line with their positions shifted, and one mark is detected by both sensors, the mark cannot be detected. The detection timing can be shifted and the same control can be performed. Further, in the embodiment described above, a feed key is used to clear a paper jam, but the present invention is not limited to this, and a dedicated switch may also be used. [Effects of the Invention] As detailed above, according to the present invention, when an accident such as a paper jam occurs during feeding, the next registration process can be prohibited until the paper jam is cleared, and overlapping printing can be prevented. Furthermore, it is possible to provide an electronic cash register that can prevent damage to the printer. Further, according to the present invention, it is possible to provide an electronic cash register that is easy to handle and can easily cancel the prohibition of registration processing and printing due to a paper jam. 4.
