Further, only the barcode 9 is printed in the arrangement of H1 to H5, and other information such as the character information 8 is not mixed in the arrangement of H1 to H5. This facilitates reading by the reading unit 81 and realizes accurate reading.

  The reading unit 81 captures the barcode 9 and performs pattern matching for information reading on the captured image. As described above, in the present embodiment, the printed barcode 9 is once captured as an image, which contributes to more accurate reading of the barcode 9.

  In the embodiment described above, for example, a part of the configuration can be appropriately changed as follows. Of course, other modifications not exemplified below are also possible.

  (A) In the above embodiment, the barcode 9 is printed in units of a pair of small pieces (see FIG. 2B), but the barcode 9 may be printed for each tablet. . Also in this case, the container film 3 of the sealing film 4 is printed on the basis of the printing means 40 for printing the barcode 9 in accordance with the mark 7 attached to the sealing film 4 and the mark 7 attached to the sealing film 4. The structure provided with the position adjustment means 22 which adjusts the attachment position with respect to is effective.

  (B) In the above embodiment, the barcode 9 is printed as a code. However, another one-dimensional code may be printed. Further, a two-dimensional code such as a QR code may be printed. Use of a two-dimensional code is advantageous in that the amount of information that can be described is further increased as compared to a one-dimensional code.

  (C) In the above embodiment, the barcode 9 includes information on the tablet 5 such as the lot number, expiration date, content, content, titer, and medicinal effect. On the other hand, the barcode 9 may include further information, or a part of the information may be included.

  (D) In the second embodiment, the reading unit 81 captures the barcode 9 and reads the barcode 9 by pattern matching based on the captured image.

  On the other hand, paying attention to the fact that the scanning direction of the bar code 9 is parallel to the transport direction as shown in FIG. The barcode 9 can be read using the above.

  (E) In the above embodiment, the display means 82a of the inspection means 82 displays the information of the barcode 9 read by the reading means 81 and the inspection result as to whether or not the information is correct. However, other information may be displayed. For example, an image of the captured barcode 9 may be displayed, or information indicating whether the barcode 9 has been mechanically read may be displayed.
