As a first modified example, the portable terminal 80 in the present embodiment may not have the forced reset start program storage section 110.

FIG. 4 shows the data structure of the program holding unit 108 of the portable terminal 80 in this example. The program holding unit 108 has a program identification information field, an external acquisition field, an acquisition date and time field, a restart activation field, a startup selection field, a reset activation field, and a program field.

The program identification information field stores program identification information for identifying a program. The external acquisition field stores a flag in association with a program acquired from the outside. This makes it possible to identify the program acquired from the outside. The acquisition date / time field stores the acquisition date / time when the program is acquired from the outside. On reboot field, after reset,
Alternatively, the flag is stored in association with the program to be started at the time of restart when it is not normally ended. The start selection field stores a flag in association with a program that the user should select whether to start the program at the time of restart. The start-on-reset field stores a flag in association with the program that was started when the forced reset unit 104 resets the program. In this case, the forced reset unit 104, before resetting,
Add a flag to the corresponding program. The program field stores a program.

In this way, the program holding unit 108
Various information is stored in association with the program identification information. Therefore, the program starting unit 102 can recognize the program to be started at the time of restart using the information stored in the program holding unit 108. Further, the display unit 820 can use the information stored in the program holding unit 108 to display the program identification information of the program that should receive an instruction from the user as to whether or not the program should be started at the time of restart.

Further, for example, the display unit 820 may display a list of program identification information of programs acquired from the outside. Further, for example, the display unit 820 may display a list of program identification information of programs to be started at the time of restart. Further, for example, the display unit 820 may display a list of the program identification information of the programs for which it should be determined whether or not to start at the time of restart, according to an instruction from the user.

The display unit 820 may also display so that it can be recognized whether or not the displayed program was activated at the time of forced reset.

As described above, the display section 820 displays various information stored in the program holding section 108 in association with the program identification information. Therefore, the user can obtain information about the program to be started when the mobile terminal 80 is restarted.

As a second modification, when the portable terminal 80 in the present embodiment receives the activation prohibition instruction, it stops the activation of the program indicated by the activation inhibition instruction. The program indicated by the start prohibition instruction may be deleted from the program holding unit 108. Also in this case, it is possible to avoid starting the defective program.

As a third modification, the program start prohibiting unit 106 in this embodiment is the instruction receiving unit 100.
Although the restart of the program indicated by the start prohibition command received via is prohibited, the restart of the program acquired from the outside may be prohibited instead.

As a fourth modification, at the time of restart, the display unit 820 displays the forced reset start program storage unit 11
Of the programs stored in 0, only the programs acquired from the outside may be displayed. As a result, the user can specify the defective program relatively easily.

As a fifth modification, the portable terminal 80 in the present embodiment receives a start prohibition instruction from the user at the time of restart, but the timing of receiving the start prohibition instruction is limited to that in the embodiment. is not. The mobile terminal 80 may accept a start prohibition instruction at the time of forced termination, for example.

As a sixth modified example, the forced reset activation program storage unit 110 in the present embodiment may store only the program acquired from the outside. As a result, the load on the mobile terminal 80 can be reduced.
