Next, the verification operation of the identification code verification apparatus 100 of this embodiment will be described.
FIG. 8 is a flowchart showing the operation of the identification code verification system of this embodiment.
In step (hereinafter referred to as S) 101, the verification machine registration data generation device 10 generates verification machine registration data and print data using the verification machine registration data generation means 11.
For example, the verifier registration data generation apparatus 10 starts a dedicated label layout creation / issuance program for operating a personal computer as the verifier registration data generation apparatus on the personal computer, so that the verifier registration data generation apparatus 10 Can be used as Then, based on the information input from the personal computer as the verification machine registration data generation device 10, verification machine registration data is generated. The verification machine registration data generation apparatus 10 generates print data for printing on the barcode label 52.
The verification machine registration data generation device 10 refers to the already generated verification machine registration data so that a different ID is assigned to each data when generating the verification machine registration data, and operates so as not to use the same ID. To do.

  In S <b> 102, the printer 20 acquires the print data generated by the verification machine registration data generation unit 11 by the printer control unit 21, and detects the label printing start position by the position detection mark 55 on the back surface.

In S103, the printer control unit 21 prints the dot pattern 52b, the barcode 52c, the barcode on the barcode label 52 on the conveyed continuous paper 50 by the printing unit based on the print data acquired in S102 and the detected label printing start position. Print data such as the code 52d is printed.
Further, the printer 20 can print the dot pattern 53b and the barcode 53c of the barcode label 53 of different types having different label sizes and types in the same manner.

  In S104, the identification code verifying apparatus 100 is generated by the verifier registration data generating unit 11 and the barcode 52c, the printing position and the print content of the barcode 52d, which are the printing results printed on the barcode label 52 in S103. The verification machine registration data is verified and verified.

  FIG. 9 is a flowchart showing a verification operation performed by the identification code verification apparatus 100 of the identification code verification system of this embodiment. The flowchart of FIG. 9 is a subroutine flow showing in detail the verification operation in S104 of FIG.

In S201, the verification machine registration data acquisition unit 131 of the identification code verification apparatus 100 includes the verification data and the ID that identifies the verification data generated by the verification machine registration data generation unit 11 of the verification machine registration data generation apparatus 10. Get verifier registration data.
In this embodiment, the verifier registration data acquisition unit 131 acquires verifier registration data from the verifier registration data generation apparatus 10 via the network 30, but verifier registration data stored in the memory card 40 or the like. May be obtained via the external memory interface 110.

  In S <b> 202, the scanner 140 reads the dot pattern 52 b printed on the barcode label 52 of the continuous paper 50. In the case of the barcode label 53, the dot pattern 53b is similarly read.

  When the identification code verification device 100 performs reading to verify the barcode label 52, the continuous paper 50 is inserted into the identification code verification device 100 from the insertion opening 116. When the continuous paper 50 is inserted from the insertion port 116, the insertion sensor 117 detects the presence of the continuous paper 50 and transmits a paper presence detection signal to the CPU 130 via the paper detection unit 104. Note that the insertion sensor 117 always monitors whether or not the continuous paper 50 is inserted from the insertion port 116.

  When a paper insertion detection signal is issued, the CPU 130 drives a motor (not shown) to drive the first transport roller 118, the second transport roller 122, and the paper discharge roller 123, respectively, the drive roller 118a, the drive roller 122a, and the drive roller 123a. Start driving. The continuous paper 50 inserted into the identification code verification device 100 is transported along the transport path and guided to the first transport roller 118. The continuous paper 50 is transported toward the discharge port 125 on the downstream side in the transport direction while being sandwiched between the driving roller 118a and the driven roller 118b. When the continuous paper 50 is conveyed by the first conveying roller 118, it is detected by the transmission sensor 119 or the reflection sensor 120. At this time, the transmission sensor 119 or the reflection sensor 120 depends on whether or not the position detection mark 55 is attached to the surface opposite to the surface on which the barcode label 52 of the mount 51 is temporarily attached, that is, depending on the type of the continuous paper 50 to be used. Either of these is used. Both sensors are used to detect the position of the bar code label 52.

  When the reflection sensor 120 does not detect the position detection mark 55, detection by the transmission sensor 119 is performed. When the reflection sensor 120 detects the position detection mark 55, for example, automatic switching such as detection by the reflection sensor 120 is performed. Further, it may be selected in advance which one of the reflection sensor 120 and the transmission sensor 119 is used. In this case, the selected information may be stored as setting information in the memory card 40, and it may be determined which sensor is used based on the setting information.

Next, the continuous paper 50 is guided between the rotary encoder 121a and the guide roller 121b, and the rotary encoder 121a and the guide roller 121b rotate following the conveyance of the continuous paper 50. The conveyance speed of the continuous paper 50 is detected by the rotation of the rotary encoder 121a, and the detected conveyance speed is transmitted to the CPU 130.
Based on the detected conveyance speed, light is emitted from the LED illumination 141 toward the barcode label 52 that passes directly under the scanner 140.

In S203, the print information acquisition unit 132 acquires the dot pattern 52b read by the scanner 140 in S202.
In S204, the ID recognition unit 133 recognizes the ID corresponding to the dot pattern 52b acquired by the print information acquisition unit 132 in S203. That is, the ID recognizing means 133 recognizes that the ID of the dot pattern 52b that has been read is ID: 1 by referring to a table (not shown) that indicates the ID. This recognized ID is an ID that identifies the barcode label to be verified (hereinafter referred to as verification target ID).

In S205, the verification unit 134 is notified of the verification target ID from the ID recognition unit 133, and specifies corresponding verification data from the verification target ID. Specifically, for example, the dot pattern 52b represents ID: 1 in the table of FIG. This ID: 1 specifies the barcode type: JAN code and CODE 39, the barcode content: 0123456789012 and ABC01234456789, the data ceiling width: B1 and B2, and the data printing position: F1 and F1 + B1 + F2 as verification data.
The same applies to the barcode label 53. That is, the dot pattern 53b represents ID = 2 in the table of FIG. This ID: 2 specifies the barcode type: CODE39, the barcode content: DEF0123456, the data ceiling width: A1, and the data printing position: F0 as the verification data.

In S <b> 206, the scanner 140 reads the barcode 52 c and the barcode 52 d printed on the barcode label 52 of the continuous paper 50.
In S207, the print information acquisition unit 132 acquires the barcode 52c and the barcode 52d read by the scanner 140.

  Note that the operation of S206 is performed continuously from the operation of reading the dot pattern 52b in S202. The operations of S203, S204, and S205 are performed in a very short time immediately after reading the dot pattern 52b in S202. Accordingly, in steps S202 to S207, the first conveyance roller 118, the second conveyance roller 122, and the like continue to convey the continuous paper 50 without stopping the operation, and the reading operation by the scanner 140 is continuously performed without stopping. .

  In S208, the verification unit 134 uses the barcode 52c and barcode 52d read by the scanner 140 in S206 and the verification data corresponding to the verification target ID specified in S205, and reads the barcode 52c and barcode 52d read. It is verified whether or not the content and position match the verification data.

Specifically, for example, for the barcode label 52, whether the barcode 52c is at the F1 data printing position, whether the data top / bottom width is the size of B1, or whether the barcode content is “012345789902”. Validate. Further, it is verified whether the barcode 52d is at the data printing position of F1 + B1 + F2, whether the data vertical width is the dimension of B2, and whether the barcode content is “ABC01234456789”. Note that if the data printing position and the top and bottom width dimensions are within the preset allowable range, it is determined that the data is correctly printed.
Further, when the barcode label 53 is verified, the verification is performed in the same manner.

  When the verification data matches the read barcode 52c and barcode 52d, the barcode label 52 on the continuous paper 50 is conveyed toward the discharge port 125, and the process returns to S104 in FIG. When the trailing edge of the conveyed continuous paper 50 is detected by the discharge sensor 124, the driving of the driving roller 118a, the driving roller 122a, and the driving roller 123a is stopped and the verification operation is finished. When the verification of the next barcode label 52 is continued, the verification operation is continued without stopping the driving.

If the discharge sensor 124 does not detect the trailing edge of the continuous paper 50, it is determined that the paper jam has occurred, and the buzzer 112 or the display unit 114 notifies the error. Instead of detection by the discharge sensor 124, the trailing end of the continuous paper 50 can be detected by stopping the rotation of the rotary encoder 121a, and it can be considered that the discharge is made from the discharge port 125 after a predetermined time has elapsed from this detection signal.
If the verification data does not match the barcodes 52c and 52d, the process proceeds to S207.

  In S209, the identification code verification device 100 performs a process of warning that the barcode label is not printed correctly. For example, the fact that the barcode label is defective is displayed on the display unit 114 of FIG.

  By performing the verification operation described above, it is possible to easily verify a plurality of different barcode labels. That is, the barcode label 53 is given an ID different from that of the barcode label 52 by the dot pattern 53b. Therefore, the identification code verification apparatus 100 is in the process of verifying the barcode label 52, when the barcode label 53 of information having a size different from that of the barcode label 52 is inserted as the next verification target. Also, necessary verification data can be specified from the ID. Further, the identification code verification device 100 can easily perform verification without newly inputting or selecting verification data.

  As described above, according to the first embodiment, the printer 20 prints the dot pattern corresponding to the verification data on the barcode label on a one-to-one basis. The identification code verification device 100 identifies verification data corresponding to the verification target ID recognized from the dot pattern, and verifies the barcode label based on the verification data. Therefore, even if the identification code verification device 100 is provided as a device independent of the printer, it can verify the barcode label. For example, barcode labels 52 and barcode labels 53 printed in advance by a printing factory, a home printer, or the like can be verified later by an identification code verification device 100 installed in a completely different place. is there. In this way, verification can be performed at a desired timing and location.

  Further, even if the barcode label is a barcode label of various types having different label sizes, types, etc., different IDs are given to the barcode label types depending on the dot pattern. Therefore, the identification code verification device 100 can specify the content (verification data) to be automatically verified from the ID without re-inputting or selecting data necessary for verification. Therefore, even when a plurality of types of barcode labels are verified, the operator can perform verification without performing a special operation.

  Furthermore, since a dot pattern representing only an ID is used on the barcode label, information printed for verification on the barcode label necessary for verification can be reduced. Therefore, it is not necessary to print a barcode for verification or the like having a large amount of information corresponding to the verification data. Therefore, the printing area of the label can be effectively used, and unnecessary verification printing can be made inconspicuous when used as a label.

Therefore, the same reference numerals are given to the portions that perform the same functions as those in the first embodiment described above, and repeated descriptions are omitted as appropriate.
The printer 20 of the first embodiment acquires only information to be printed on the print medium as print data, whereas the printer 20B of the second embodiment acquires verification machine registration data.
The printer control unit 21B generates print data of the barcode label selected by the operator from the acquired verification machine registration data, and prints it on the print medium.
The verification machine registration data acquisition unit 131 of the identification code verification apparatus 100 acquires verification machine registration data acquired by the printer 20B from the printer control unit 21B of the printer 20B.
That is, in the second embodiment, the verification machine registration data generated by the verification machine registration data generation apparatus 10 is acquired by the identification code verification apparatus 100 via the printer 20B. Others are the same as in the first embodiment.

  According to the second embodiment, the verification machine registration data generated by the verification machine registration data generation device 10 need only be sent to the printer 20B. Therefore, it is possible to simplify the work of separately generating the verification machine registration data and the print data and sending them to the identification code verification device or the printer.

(Third embodiment)
FIG. 11 is a diagram showing a third embodiment of an identification code verification system using the identification code verification device 100C according to the present invention.

That is, the scanner 140C only needs to be able to read the print medium and output the data. Further, the identification code verification device 100C only needs to be able to acquire the print medium unique information and the identification code from the scanner 140C, and to perform arithmetic processing and output of the result as the verification device. Therefore, a general-purpose scanner can be used as the scanner 140C. A general-purpose personal computer can be used as the identification code verification device 100C. In that case, a program capable of realizing the operation necessary for the identification code verification apparatus may be installed in the personal computer and executed.
