Next, in step s2, the microcomputer unit 14 determines whether or not the “AUTO” key part of the “LOG” key part on the two-dimensional code image detail setting screen 3B shown in FIG. If the “AUTO” key is selected, the process proceeds to step s3. If the “AUTO” key is not selected, the process proceeds to step s4.

  In step s8, the microcomputer unit 14 determines whether or not the “ENTER” key part on the two-dimensional code image detail setting screen 3B shown in FIG. 2B is selected. If the “ENTER” key part is selected, the process proceeds to step s9. If the “ENTER” key part is not selected, the process returns to step s5.

  In step s9, the microcomputer unit 14 updates the information stored in the nonvolatile memory unit 15A.

  In step s10, the microcomputer unit 14 determines whether or not the “MANUAL” key part of the “LOG” key part on the two-dimensional code image detailed setting screen 3B shown in FIG. 2B is selected. If the “MANUAL” key part is selected, the process proceeds to step s11. If the “MANUAL” key part is not selected and the “AUTO” key part is selected, the process returns to step s4.

  In step s11, the microcomputer unit 14 causes the time measuring unit 18 to reset the time measurement. Next, in step s12, the microcomputer unit 14 reads e-mail address information added to the log information stored in the nonvolatile memory unit 15A.

  In step s15, the microcomputer unit 14 converts the processing content information included in the log information into a two-dimensional code, and generates two-dimensional code image data corresponding to the converted two-dimensional code. Further, the microcomputer unit 14 outputs the generated two-dimensional code image data to the display unit 11.

  Next, in step s16, the display unit 11 controlled by the microcomputer unit 14 displays a two-dimensional code image based on the two-dimensional code image data.

  Next, in step s17, the microcomputer unit 14 determines whether or not a predetermined time has elapsed since the display of the two-dimensional code image on the display unit 11 based on the timing information of the timing unit 18. If it is determined that the predetermined time has elapsed, the process returns to step s4. If it is determined that the predetermined time has not elapsed, the process proceeds to step s18.

  In step s18, the microcomputer unit 14 determines whether an instruction to stop the display operation of the two-dimensional code image has been input by the remote operation device. If it is determined that an instruction to stop the display operation of the two-dimensional code image has been input, the process returns to step s4. If it is determined that no instruction has been input, the process returns to step s17. As described above, the display device 1 performs an operation for displaying a two-dimensional code image.

  In step a2, the control unit 26 determines whether or not the two-dimensional code image data stored in the two-dimensional code image data storage unit 22 should be transmitted to the external terminal device. When the e-mail address information is added to the two-dimensional code image data acquired by the imaging unit 21, the control unit 26 determines that it should be transmitted to the external terminal device, and proceeds to step a3. If the e-mail address information is not added to the code image data, it is determined that it should not be transmitted to the external terminal device, and the process proceeds to step a4.

  In step a3, the transmission unit 24 transmits the two-dimensional code image data to the external terminal device according to the e-mail address information.

  In step a4, the decoding processing unit 23 decodes the two-dimensional code image data, and acquires processing content information corresponding to the two-dimensional code.
