After searching for the new member 4 to be added, existing member A taps the member addition button 38B. The input data acquisition unit 20 acquires input data generated by tapping the member addition button 38B (step S21).

[0134] The group creating unit 21 adds a new member 4 based on the input data acquired in step S21 (step S22). The added new member 4 is registered in the group storage unit 26.

[0135] Furthermore, when the add member button 38B is tapped, the display control unit 25 displays the member setting screen 39 shown in Figures 17 and 18. Existing member A inputs the role of the new member 4, checks a check box 39E to set the usage authority for the application software 15, and then taps the confirm button 39F. The input data acquisition unit 20 acquires the input data generated when the confirm button 39F is tapped (step S23).

[0136] The access permission unit 23 determines whether the existing member A has the authority to set the new member 4's usage authority for the application software 15 (step S24). The existing member A's usage authority for the application software 15 is stored in the group storage unit 26. The access permission unit 23 determines whether the existing member A has the authority to set the new member 4's usage authority based on the existing member A's usage authority stored in the group storage unit 26.

[0137] In step S24, if it is determined that existing member A has the authority to set usage rights for new member 4 (step S24: Yes), the authority setting unit 24 sets usage rights for the application software 15 for the new member 4 based on the input data acquired in step S23 (step S25).

[0138] In step S24, if it is determined that existing member A does not have the authority to set usage rights for new member 4 (step S24: No), the authority setting unit 24 does not set usage rights for the application software 15 for the new member 4.

[0139] If the existing member A has the authority to add the new member 4, it is not necessary to determine (step S24) whether the existing member A has the authority to set the usage authority of the application software 15 for the new member 4. If the existing member A has the authority to add the new member 4, the processing of step S24 may not be performed, and the authority setting unit 24 may set the usage authority of the application software 15 for the new member 4 based on the input data acquired in step S23.

[0140] <Viewing of inspection sheet by member> Figure 34 is a flowchart showing the procedure for member A to view the inspection sheet. To view the inspection sheet, member A taps the inspection button 33D on the individual vehicle screen 33 shown in Figure 9. The input data acquisition unit 20 acquires the input data generated by tapping the inspection button 33D (step S31).

[0141] The access permission unit 23 determines whether or not member A has the authority to view the checklist (step S32). Member A's authority to view the checklist is stored in the group storage unit 26. The access permission unit 23 determines whether or not member A has the authority to view the checklist based on member A's use authority for application software 15, which is stored in the group storage unit 26.

[0142] In step S32, if it is determined that member A has the authority to view the inspection sheet (step S32: Yes), the access permission unit 23 permits member A to view the inspection sheet. Based on the input data acquired in step S31, the display control unit 25 causes the display device 11 to display the inspection screen 34 shown in Fig. 10 (step S33).

[0143] If it is determined in step S32 that member A does not have the authority to view the inspection sheet (step S24: No), the access permission unit 23 prohibits member A from viewing the inspection sheet. The display control unit 25 does not display the inspection screen 34 on the display device 11.
