  If the result of determination is that the flying object 100 is in flight (step S101, Yes), the controller 10 determines whether a predetermined event has occurred (step S102).

  If a predetermined event occurs as a result of the determination (step S102, Yes), the controller 10 determines whether the security lock state is set (step S103).

  When the controller 10 is in the security lock state as a result of the determination (step S103, Yes), the controller 10 determines whether the distance to the user measured in the flying object 100 is less than the threshold (step S104). The user is a user of the mobile terminal 1 mounted on the flying object 100.

For example, a fingerprint sensor that acquires a fingerprint through an operation on the connection frame 130 may be mounted on the sensor unit 125 and the acquired fingerprint data may be transmitted to the mobile terminal 1. For example, the mobile terminal 1 may directly determine whether the user has approached a predetermined distance range based on the measurement result of the distance image sensor 125b.

The portable terminal 1 may be set so as to be in the security lock state again when it is detected that it is not in flight after releasing the security lock during flight. Since such a portable terminal 1 does not enter a security locked state until it is detected that it is not in flight once the security lock is released during the flight, the user releases the security lock during the flight of the portable terminal 1. The mobile terminal 1 in flight can be operated without performing the operation many times. Moreover, since the portable terminal 1 will be in a security lock state again, if it detects that it is not in flight, it can ensure a certain security level.

  When the security lock is released during the flight, the portable terminal 1 may not be in the sleep state until it is detected that the predetermined operation instruction is not received even if the state where the predetermined operation instruction is not received continues. The portable terminal 1 may be set to sleep when it detects that it is not in flight after releasing the security lock during flight. Since such a portable terminal 1 does not enter a sleep state until it is detected that it is not in flight once the security lock is released during the flight, the user returns from the sleep state during the flight of the portable terminal 1. It is possible to operate the mobile terminal 1 in flight without performing the operation.
