Since the amount of light emitted from the illumination unit of the scanner is constant, if the conveyance speed of the printing medium changes (the conveyance speed increases), the exposure amount for the barcode becomes excessive and insufficient, and reading errors often occur. For this reason, the printing medium on which the barcode to be read is printed is conveyed at a slow conveyance speed (printing speed) that matches the exposure amount that can be read by the scanner, or the conveyance is temporarily stopped at the reading timing of the scanner. This is handled by an intermittent conveyance operation that resumes conveyance after reading. However, if the transport speed is slowed or intermittent transport is performed, there is a problem that the amount of issue per unit time in the printer decreases.

In the LED irradiation amount table, the higher the conveyance speed, the larger the irradiation amount from the LED, and the lower the conveyance speed, the smaller the irradiation amount from the LED, and the conveyance is performed without decelerating or stopping the conveyance. An optimum irradiation amount of the LED capable of reading the barcode 65 of the continuous paper 61 conveyed at the speed is set. In addition, the code type of the identification code to be verified by the verification device and the printing position of the identification code can be input from the input unit and set as setting information in the external memory 54 or the like, thereby speeding up the processing. And accuracy can be improved.

  Based on the structure described above, the barcode verification operation in the verification apparatus will be described with reference to the flowchart of FIG. Information such as a bar code 65 is printed while the label 63 is conveyed by the printing unit 4 of the printer 1, and the continuous paper 61 discharged from the discharge port 7 is guided to the guide plate 35, and is inserted into the verification device 20 from the insertion port 23. It is inserted inside. When the continuous paper 61 is inserted from the insertion port 23, the insertion sensor 24 detects the presence of the continuous paper 61 and transmits a paper presence detection signal to the CPU via the paper detection unit 45 (step S1). The insertion sensor 24 always monitors whether or not the continuous paper 61 is inserted from the insertion port 23.

  When a paper insertion detection signal is issued, a motor (not shown) is driven to start driving of the first transport roller 25, the second transport roller 30, and the discharge roller 32, ie, the drive rollers 25a, 30a, and 32a (step S2). . The continuous paper 61 inserted into the verification device is transported by the platen roller 9 of the printer 1 along the transport path and is guided to the first transport roller 25. The continuous paper 61 is transported toward the discharge port 34 on the downstream side in the transport direction while being sandwiched between the driving roller 25a and the driven roller 25b. When the continuous paper 61 is conveyed by the first conveying roller 25, it is detected by the transmission sensor 26 or the reflection sensor 27 (step S3). At this time, depending on whether or not an identification mark is attached to the surface opposite to the surface on which the label 63 of the release paper 62 is temporarily attached, that is, depending on the type of the continuous paper 61 used in the printer 1, Either one is used, and any sensor is used to detect the position of the label 63. When the reflection sensor 27 does not detect the identification mark, detection by the transmission sensor 26 is performed, and when the reflection sensor 27 detects the identification mark, automatic switching such as detection by the reflection sensor 27 is performed. It may be selected from the input unit as to which one of the transmission sensors 26 is used, the selected information is stored as setting information in the external memory 54, and which sensor is used is determined based on the setting information. .

  Next, the continuous paper 61 is guided between the rotary encoder 28a and the guide roller 28b, and the rotary encoder 28a and the guide roller 28b rotate following the conveyance of the continuous paper 61. The conveyance speed of the continuous paper 61 is detected by the rotation of the rotary encoder, and is transmitted to the CPU via the speed detection unit 46 (step S4).

  Based on the conveyance speed detected by the speed detection unit 46, the dose corresponding to the detected conveyance speed is read from the LED dose table stored in the external memory 54 (step S5). Based on the irradiation amount read from the external memory 54, light is emitted from the LED illumination 70 toward the barcode 65 of the label 63 that passes directly under the scanner unit 29 (step S6).

  The light emitted from the LED illumination 70 and reflected by the bar code 65 is received by the line CCD sensor 73, analyzed by the reading control unit 47, and the information of the bar code 65 is read (step S7).

It is determined whether or not the bar code 65 analyzed by the reading control unit 47 can be read (step S8). If the bar code 65 can be read, it is conveyed toward the discharge port 34 by the discharge roller 32.
If it is determined in step S8 that the bar code 65 analyzed by the reading control unit 47 is unreadable, the error control unit 31 is driven by the print control unit 48, and the label on which the unreadable bar code 65 is printed. Error printing 68 is performed on 63 as shown in FIG. 7 (step S10).

  FIG. 7 is a plan view of continuous paper on which error printing has been performed. As shown in FIG. 7, the printing unit 4 is attached to the labels 63a, 63b, and 63c temporarily attached on the release paper 62 in order from the downstream side in the transport direction. Thus, the character information 66 and the barcode 65 as an identification code are printed. The bar code 65 printed on the label 63a is printed neatly with no defective printing, and is judged to be readable by the reading control unit 47 without any reading error, and no error printing is performed. On the other hand, due to damage to the heating element of the thermal head 8 or the like, a print omission 67 occurs in a part of the character information 66 or bar code 65 printed on the labels 63b and 63c. It is determined that the data cannot be read, and the error printing unit 31 performs error printing 68.

  Next, the trailing edge of the conveyed continuous paper 61 is detected by the discharge sensor 33 (step S9), and when detected, driving of the drive rollers 25a, 30a, and 32a is stopped and the verification operation is finished. If the discharge sensor 33 does not detect the trailing edge of the continuous paper 61 in step S9, it is determined that there is an error such as a paper jam and the error is notified by a buzzer or a display unit (step S11).

  Further, in step S9, instead of detection by the discharge sensor 33, the trailing edge of the continuous paper 61 is detected by stopping the rotation of the rotary encoder 28a, and it is considered that the discharge is performed from the discharge port 34 after a predetermined time has elapsed from this detection signal. it can.

  As described above, in the embodiment of the present invention, the conveyance speed at which the continuous paper 60 is conveyed is detected by the rotary encoder 28a, and the barcode 65 printed on the label 63 can be read while being conveyed at this conveyance speed (optimum). By reading the value from the table and controlling the drive current by means such as controlling the current value for driving the LED based on this value or changing the rate of the LED drive current pulse, the transport speed in the printer 1 changes. Even in this case, the bar code 65 printed on the continuous paper 61 can be read.

In addition to the structure of the control unit 40, the control unit of the verification apparatus according to the second embodiment includes a determination unit that determines the reading performance (reading grade) of the barcode 65 read by the scanner unit 29. Since the reading of the bar code 65 is also caused by the performance of the bar code scanner, an error may occur if the bar code 65 that has not been read by the verification device is read by a bar code scanner having a low performance. For this reason, a barcode that can be read by any barcode scanner having a low reading performance by making a barcode 65 having a reading performance below a certain level as an error is provided with a determination means for determining the reading performance that is the barcode 65 printing quality. Can be provided.
The reading grade is determined based on a verification method stipulated in standards such as ANSIX 3.182 and JISX0502. Judged by grade. In actual operation, a reference grade reading grade that is an error in advance is input from the input unit, the reading grade of the reference value input from the input unit is compared with the reading grade determined by the determining means, and the determined reading grade is determined. Is below the reading grade of the reference value input and set from the input unit, the error printing unit 31 is driven to perform error printing 68. When error printing is performed, the conveyance of the continuous paper 61 is stopped and a buzzer, a display unit, or a computer connected to the verification device 20 is notified.

In the embodiment of the present invention, the object to be verified by the scanner unit is a barcode. However, the present invention is not limited to this, and any identification code that can be read by a reading method using reflected light of irradiated light may be used. Etc. Further, by using a CCD image sensor as the scanner unit, it can be applied to recognition of character data such as a date other than the identification code, or a seal.
It can be applied to recognition of marks and the like.
