Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slip printing device that is used by being connected to an electronic cash register or a terminal of a PO8 (point of sale) system.

[Prior Art] Electronic cash registers that perform sales registration processing for each sold product can issue various slips such as delivery slips and credit slips by connecting a slip printer to a slip printer. There is. However, since each of these slips has a different printing format, the electronic cash register's CPU (central processing unit)
, programs corresponding to the printing format of each slip are managed for each slip type. Then, when the type of issued slip is designated by operating a slip type designation key, etc., the slip data is edited according to the selected slip type, and the slip data is sent to the slip printer together with the format data.

In a slip printer, after confirming that the slip paper is inserted into the slip paper insertion slot, the slip paper is transported and the slip data is printed on the slip paper in the format specified by the format data.

[Problems to be Solved by the Invention] As described above, conventionally, it has been necessary to manage a program corresponding to the printing format of a slip for each slip in the control unit that controls the slip printer (for example, the CPU of an electronic cash register). Ta. For this reason, some stores have requests to change the printing format of each slip as appropriate, but in that case, complicated program changes are required.
I had no choice but to waste time and effort.

Furthermore, in conventional slip printers, as long as a sheet of paper is inserted into the slip insertion slot, slip data is printed on the sheet according to a predetermined printing format in response to a slip type designation operation.

For this reason, even if a slip paper of a different type than the one specified by the slip type specification operation is inserted, the slip will be printed, resulting in a waste of slip paper, and the printing will erase the slip data. There was a problem where you had to re-register because it would be deleted.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a slip printing device that can print various slips with different printing formats without managing programs corresponding to the printing formats of various slips, and that can easily change the printing format. It is.

Furthermore, it is an object of the present invention to provide a slip printing device that can prohibit a slip printing operation when a slip sheet different from the type specified by the slip type designation operation is inserted.

[Means for Solving the Problems] The present invention edits the slip data according to the slip type specified by the slip type designation operation, and corresponds to the slip type while conveying the slip paper inserted into the slip insertion slot. In a slip printing device that prints slip data in a printing format that corresponds to the printing format, a barcode reading means for reading a barcode from slip paper on which a barcode string corresponding to the printing format is printed is arranged near the slip insertion slot, and the barcode reading means is arranged near the slip insertion slot. A printing item recognition means for recognizing a printing item from a barcode read by a reading means, and a slip for printing slip data corresponding to the printing item recognized by the recognition means on slip paper on which the barcode string is printed. The printer is equipped with a printing control means.

Then, a barcode row corresponding to the print format is printed near one side of the slip paper in parallel to the conveying direction in units of one feed, and a barcode reading device prints a barcode row on the slip paper near the slip insertion slot. It is desirable to fix the barcode at a position where the code can be read, and read the barcode sequentially each time a slip is fed.

In addition, on the slip paper, a barcode corresponding to the slip type is printed at the beginning of the barcode string corresponding to the printing format, the slip type is recognized from the first barcode read by the barcode reader, and the slip type is specified by the slip type specification operation. It is preferable to provide means for comparing and collating the specified slip type and prohibiting the slip printing operation if there is a mismatch.

Further, a means may be provided for detecting that a slip (paper) is inserted into the slip insertion slot based on the output of the barcode reading device.

[Function] With a slip printing device that takes such measures, if a slip with a barcode string corresponding to the printing format printed is inserted into the slip insertion slot, and the slip type is specified using the slip type specification operation, , the slip data is edited according to the type, the barcode of the slip is read by a barcode reading device, the print item is recognized from the barcode, and the corresponding slip data is printed on the slip.

By using slip paper on which barcode rows corresponding to the printing format are printed parallel to the conveyance direction in units of feed, the barcode reading device is fixed at a position near the slip paper insertion slot where the barcode can be read. Just leave it there.

In addition, by using slip paper with a barcode corresponding to the slip type printed at the beginning of the barcode string corresponding to the printing format, the type of slip paper can be recognized by reading the first barcode with a barcode reading device, and the slip paper If the slip type does not match the slip type specified by the type designation operation, the slip printing operation is prohibited.

Moreover, it is confirmed that the slip paper is inserted into the slip insertion slot based on the output of the barcode reading device.

In addition to the R/J printer interface 27 that drives and controls the R/J printer, the display control circuit 28 that drives and controls each of the displays 6.8, and the like, there is also a code reading unit that reads codes from the barcode league head 15 in the slip printer 2. A barcode decoder circuit 29 that takes in and decodes signals, and a slip printer interface 30 that connects the slip printer 30 to the CPU via the path line 21.
20.

The barcode reader 15 and the barcode decoder circuit 29 constitute a barcode reader, and FIG. 3 is a circuit diagram of this barcode reader. The barcode league head 15 has a configuration in which a phototransistor 32 as a light receiving element receives reflected light emitted from a photodiode 31 as a light emitting element, and an output signal from the phototransistor 32 is sent to a barcode decoder. Amplifier 3 of circuit 29
After amplification in step 3, the signal is input to the waveform shaping circuit 34 as a code reading signal α as shown in FIG. 4, for example. The white part of the barcode has a high reflectance, so the level of this code reading signal α is high, and the black part has a low reflectance +τ, so the level is low. After shaping the waveform of 10 waves, the level is inverted, for example. It is output to the decoder 35 as a pulse signal β as shown in FIG. In this case, the white part of the barcode becomes a low level, and the black part becomes a high level. The decoder 35 decodes the pulse signal β, decodes the character code corresponding to the barcode, and outputs it to the CPU 20.

Further, as shown in FIG. 6, the slip paper 13 used in this embodiment has a barcode row 40 printed in parallel to the transport direction X in the vicinity of one side of the paper in units of one feed. . The barcode 41 at the beginning of the barcode string 40 is a barcode corresponding to a character code set according to the type of slip. It is set as follows.

The leading barcode 41 is printed at a position where the slip paper 13 is read by the barcode league head 15 when the slip paper 13 is inserted into the slip insertion slot 12 of the slip printer 2 and conveyed by one feed.

In addition, barcodes 42 to 47 are barcodes corresponding to the character codes set for each print item making up the print format, and the character codes corresponding to the print items are set as shown in Table 2 below. has been done.

Table 2 Therefore, in the case of the delivery slip in Figure 6, barcode 41
corresponds to the character code "0°," below, barcode 42 is the character code C, barcode 43 is the character code "b",
The barcode 44 corresponds to the character code a, the barcode 45 corresponds to the character code barcode 46 corresponds to the character code "+", the barcode 47 corresponds to the character code "tm," and the <- code 48 corresponds to the character code ``''/''. , the areas of each print item corresponding to the barcodes 42 to 48 of the print format are the barcode reader head 15 and the print head 14, respectively.
are printed in advance at a distance p from the

Note that the resolution of a barcode is, for example, if one digit that can represent 22 character types is represented by one feed using the NW-7 code, (feed amount of one digit) / (l feed amount) - 4,23u
/20+IJl"=i0.212a, which is the resolution of a barcode league head for boat fishing.

The CPU 20 is programmed to execute the process shown in FIG. 7 when the slip type designation key on the keyboard 4 is operated.

That is, as ST (step) 1, the slip data is edited to be printed on the slip according to the slip type specified by the key operation, and is stored in the RAM 23. Then,
The output signal from the barcode league head 15 is decoded by the barcode decoder circuit 29, the result is taken in, and ST2
Insert slip paper 1 into slip insertion slot 12 of slip printer 2.
3 is inserted. In this step, if the slip paper 13 has been inserted, the barcode league head 15 will detect the white of the paper and all the outputs of the waveform shaping circuit 34 will be at a low level, so it is determined that paper is present at this time, and conversely, the slip paper 13 is inserted. If the paper 13 is not inserted, the barcode league head 15 detects a dark area in the insertion slot, and all outputs of the waveform shaping circuit 34 become low level, so that it is determined that there is no paper. If there is no paper, the buzzer 24 is sounded as an error, and the process is ended.

On the other hand, if there is paper, the slip printer interface 30 sends a feed command and inserts the paper into the insertion slot 1.
The slip paper 13 inserted into the slot 2 is fed one time in the X direction. Then, the result of decoding the output signal from the barcode league head 15 by the barcode decoder circuit 29 is taken in again.

At this time, the first barcode 41 of the barcode string 40 printed on the slip paper 13 is read by the barcode league head 15, so the slip type corresponding to the character code decoded as ST3 and the slip specified by key operation are read. Determine whether the types match. If there is a mismatch, the buzzer 24 sounds as an error because a slip with a format different from that intended for printing has been inserted, and a command is output to the slip printer interface 30 to reverse feed the slip paper 13 to perform the slip printing operation. prohibited.

On the other hand, if the two match, a slip with a format corresponding to the printing purpose has been inserted, so the result of decoding the output signal from the RAD 15 by the barcode decoder circuit 29 is read into the barcode reader again. At this time, the second barcode 42 of the barcode string 40 printed on the slip paper 13 is read by the barcode league head 15, so four print items corresponding to the decoded character code are selected, and this print item is read by the barcode league head 15. Execute processing accordingly.

That is, if the result of decoding the barcode is the character code "a", the amount data is read out from the edited slip data stored in the RAM 23 and sent to the slip printer interface 30, and then the feed command is sent. Send. Similarly, if the barcode decoding result is the character code "b", the unit price 2 quantity data is read out, if the character code is "C", the product name data is read out, and if the character code is "+", the shipping fee data is read out. If the character code is "t", the total data is read out and sent to the slip printer interface 30, and then a feed command is sent out.

If the result of decoding the barcode is the character code "," it is non-print data, so a feed command is sent immediately. Also, if the result of decoding the barcode is the character code "/#, it is end data, so this process ends. do.

In this embodiment with such a configuration, when the slip paper 13 shown in FIG. 6 is inserted into the slip insertion slot 12 of the slip printer 2 and the delivery slip designation key on the keyboard 4 of the electronic cash register 1 is operated, After the slip data regarding the conveyance slip is edited, the presence or absence of paper is determined from the output of the barcode league head 15. in this case,
The barcode read head 15 reads the white portion above the slip paper, and the output of the waveform shaping circuit 34 becomes low level, so it is determined that paper is present, and the slip paper 13 is conveyed by one feed.

Next, the first barcode of the barcode string 40 printed on the slip paper 13 is read by the barcode league head 15, its character code is decoded, and the slip type is recognized based on Table 1. Then, the recognized slip type and the slip type specified by the key operation are compared and checked to determine whether they match. In this case, since the two match, the slip paper 13 is conveyed by one feed.

Next, the second barcode 42 in the barcode sequence 40 is read by the barcode league head 15, its character code is decoded, and the printed item is recognized based on the second table. In this case, the character code is “C” and the item is “Product name”.
Therefore, the product name data is sent from the edited slip data to the slip printer 2, and the print head 14 prints the product name. After that, the slip paper 13 is conveyed by one feed, and the third barcode 4 in the barcode row 40 is
3 is read and the same printing process is performed.

In this way, barcodes 42 to 48 of the barcode string 4 are read out in sequence every time the e-feed is performed, and the corresponding slip data is printed on the slip paper 13 in a printing format corresponding to this barcode. Then, when the barcode corresponding to the character code "/" of the print item "end" is read, the printing process ends.

As described above, according to this embodiment, by using slip paper on which a barcode string corresponding to the printing format is printed, the printing process of the slip data is performed according to the printing format of this barcode string, and the required slip is printed. Therefore, it is possible to issue a slip having an arbitrary print format without managing a program corresponding to the print format. Therefore, even when changing the printing format of a slip, it is only necessary to change the barcode string printed on the slip paper, so it can be easily carried out, and the format can be changed in a short time, improving practicality.

Further, as shown in FIG. 6, by printing the barcode row 40 printed on the slip paper 13 in parallel to the conveyance direction in units of one feed, the barcode read head
5 need only be fixed at a position near the slip insertion slot 12 where the bar code of the slip paper 13 can be read, which simplifies the structure.

Furthermore, since the presence or absence of paper can be determined based on the reading output of the RAD 15 to the barcode league, the paper sensor required in conventional slip printers can be omitted.

In addition, by printing a barcode corresponding to the document type at the beginning of the barcode column on the document, it is possible to compare the document type recognized by reading this first barcode with the document type specified by the document type specification operation. Since the printing operation is prohibited after verification and if there is a discrepancy, there is no risk that printing will be executed even if a slip paper different from the slip paper intended for printing is inserted by mistake, and paper wastage can be prevented. Since there is no risk that the slip data will disappear due to printing, there is no need for re-registration.

Note that the present invention is not limited to the above embodiments.

For example, in the above embodiment, only the barcode string 40 corresponding to the printing format is printed on the slip paper 13, but as shown in FIG. The printing position may be designated by the number of digits, and a barcode string 50 in which data corresponding to the number of digits is converted into a barcode may be provided in parallel with the barcode string 40. By doing this, although two barcode league heads are required, the printing format can be set more freely. In this case, by using a high-density barcode that can express a two-character code in one feed, the barcode row can be made into one row, and an increase in the number of barcode reader heads can be avoided.

Further, in the above embodiment, the case where the barcode row is provided parallel to the transport direction The same effect can be obtained by printing a barcode string, reading this barcode string before starting the printing operation using a barcode league head that scans in the same direction as the print head 14, and printing the barcode string in the order in which it is read. However, in this case, a memory is required to store information on the read barcode string, and the configuration of the barcode league head becomes complicated.

In addition, it goes without saying that various modifications can be made to the slip type designation operation, the configuration of the barcode decoder circuit, etc. without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to print various types of vouchers with different printing formats without managing programs corresponding to the printing formats of various vouchers, and it is possible to easily change the printing format. It is possible to provide a slip printing device that can perform the following operations.

According to the second aspect, since the barcode reading device can be fixed near the slip insertion slot, it is possible to provide a slip printing device that does not have a complicated structure.

Further, according to claim 3, it is possible to provide a slip printing device that can prohibit the slip printing operation when a slip sheet different from the type specified by the slip type designation operation is inserted.

Furthermore, according to claim 4, since the presence or absence of paper can be determined based on the output of the barcode reading device, it is possible to provide a slip printing device in which a paper sensor can be omitted.
