The issued character data is displayed. Therefore, the two-dimensional code reader 10 of the second embodiment does not include a liquid crystal display as shown in FIG. 8, and data is transmitted to the computer 50 side via the cable 18 by the communication interface 48.

The configuration of the multilingual QR code is the same as that in the first embodiment. However, in the first embodiment, the designation of the reading language is set by the operation switch 42, but in the second embodiment, the language is designated by reading the QR code for writing the control software. Specifically, once the control software writing QR code QC shown in FIG. 5B is read once, it becomes possible to read the character information of the specified language from the multilingual QR code Q. .

The reading process of the control software writing QR code QC and the multilingual QR code Q shown in FIG. 5B by the two-dimensional code reader 10 of the second embodiment will be described with reference to FIG.
Here, first, the processing when the QR code QC for writing control software is read will be described. An image of the QR code QC for writing control software is acquired (S22), and is decoded into binary information based on the acquired contrast for each cell (S24). If decoding is possible (S26: Yes), it is determined whether the corresponding language information (control software) is read (S38), but here, the QR code QC for writing control software is read (S38: Yes) First, the corresponding language information, that is, “932” indicating Japanese, the identifier “01” indicating the numeric mode (common character), and the identifier indicating the alphabetic symbol mode (common character) Control information (control software) for reading the recording area including “02” is written in the memory 35 (S40). Then, the corresponding language information (control software) performed on the computer 50 side is transmitted to the computer 50 side. Thereafter, the determination in step S44 as to whether or not there is a host (computer) compatible language is No, and the processing is terminated by reading the terminator provided in the QR code QC for writing control software (S50: Yes).

Next, processing when the multilingual QR code Q is read will be described. An image of the multilingual QR code Q is acquired (S22), and is decoded into binary information based on the acquired contrast for each cell (S24). If decoding is possible (S26: Yes), it is determined whether the corresponding language information (control software) is read (S38). Here, since the multilingual QR code Q is read (S38: No), S44 is performed. And the corresponding language identifier of the host (computer 50), that is, “932” indicating Japanese, the identifier “01” indicating the numeric mode (common character), and the alphabetic symbol mode (common character). It is determined whether or not the identifier “02” indicating “?” Has been read (S44). Here, for example, when the recording area E1 described above with reference to FIG. 3B is read and the identifier [932] indicating Japanese is included in the identification area ei (S44: Yes), The recording area E1 is specified (S46). Then, the data in the recording area E1 is transmitted to the host (computer 50) side (S48). This process is continued until the terminator is read (S50: No), and when the terminator is read (S50: Yes), the process ends.

Next, processing on the computer 50 side when the control software writing QR code QC is read by the two-dimensional code reader 10 will be described with reference to FIG.
Data is received (S52), and it is determined whether the corresponding language information (control software) transmitted from the two-dimensional code reader 10 side on the computer 50 side is transmitted (S54). Here, since the control software performed on the computer 50 side is transmitted from the two-dimensional code reader 10 side (S54: Yes), the corresponding language information (control software) is installed in a memory (not shown) of the computer 50. (S56). Then, upon reception of the read data of the terminator provided in the control software writing QR code QC (S58: Yes), the process is terminated.

Finally, processing on the computer 50 side when the multilingual QR code Q is read by the two-dimensional code reader 10 will be described. Note that the code page can be read by the application software of the computer 50 by using, for example, Win32 API GetACP (), GetOEMCP (), or the like. First, reception of data is started (S52). Here, the determination in S54 as to whether the corresponding language information (control software) has been transmitted is No, and the determination in S58 as to whether the terminator has been read out becomes No, and the record corresponding to the corresponding language identifier of the host (computer 50). It is determined whether the area data has been sent (S60). Here, when the data in the recording area corresponding to the corresponding language identifier is sent (S60: Yes), it is determined whether the characters of the sent data are displayable characters (S62). (S62: Yes), the data is decoded into characters and displayed on the display 52 (S66). On the other hand, when the character cannot be displayed (S62: No), a process of skipping the character is performed (processed as a space). Then, upon reception of the data read from the terminator T provided in the multilingual QR code Q (S58: Yes), the process is terminated.

In the second embodiment, since the designation of the reading language is performed by reading the control software writing QR code QC including the control information for performing the designation, the reading language can be easily designated. In the second embodiment as well, the language can be specified by a switch operation as in the first embodiment.

In the second embodiment, when the information on the recording area is displayed as read data on the computer 50 side, it is determined whether the character information can be displayed on the display 52, and only the character information that can be displayed is decoded. To display. For this reason, a phenomenon such as garbled characters does not occur.

In the second embodiment described above, the reading language is designated by the QR code. However, it is also possible to install the control software directly on the computer and transfer necessary control information from the computer side to the two-dimensional code reader 10. It is possible. In the second embodiment, the two-dimensional code reader 10 transmits only information on a recording area of a preset corresponding language to the computer 50 side. However, all information is transmitted from the two-dimensional code reader 10 to the computer 50 side. It is also possible to configure such that the transmission area is in the computer 50 and the recording area of the setting-corresponding language is specified and decoded into character data. However, the configuration in which transmission data is selected by the two-dimensional code reader 10 has an advantage that the amount of data transmission can be reduced. On the other hand, in the method of transmitting all data, the processing burden on the two-dimensional code reader 10 side is increased. There is a low advantage.
