That is, the mode of the mobile phone with GPS function 1 is set as an emergency mode (step S3).
Subsequently, the setting of the destination mail address for notifying the current location in the emergency mode is received and set from the user (step S4), and the process is terminated.

If the instruction to turn on the emergency mode is not accepted in step S2 (step S2: NO), the flag information is not stored in the storage unit 15 and is not in the emergency mode, that is, in the normal mode (step S5). ) To finish the process.
Next, position information transmission processing performed when the emergency mode is set will be described.

FIG. 4 is a flowchart used for explaining the position information transmission process in the emergency mode of the cellular phone 1 with a GPS function.
First, when the mobile phone 1 with GPS function is turned on, if the user presses the power button, that is, receives an instruction to turn off the power from the user (step S11: YES), the control unit 14 stores the information. It is checked whether flag information indicating that the emergency mode is on is stored in the unit 15, that is, whether or not the own device is set to the emergency mode (step S12).

  If the own device is set to the emergency mode (step S12: YES), the control unit 14 causes the GPS processing unit 7 to perform GPS positioning and obtains position information indicating the current location of the own device (step S13). . Subsequently, the control unit 14 creates an e-mail addressed to a preset e-mail address describing the position information, and transmits the e-mail via the wireless communication unit 5 (step S14).

Thereafter, the control unit 14 includes functional units other than the power supply circuit 11, the time measuring unit 12, and the control unit 14 illustrated in FIG. 2, that is, the operation unit 2, the display unit 3, the wireless communication unit 5, the GPS processing unit 7, and the speaker unit 8.

First, when the mobile phone with GPS function 1 is turned on, if the user presses the power button, that is, receives an instruction to turn off the power from the user (step S21: YES), the control unit 14 stores the storage unit. It is checked whether flag information indicating that the emergency mode is on is stored in FIG. 15, that is, whether the emergency mode is set (step S22).

If the emergency mode is set (step S22: YES), the control unit 14 performs a power-off process for stopping the power supply to the functional units other than the power supply circuit 11, the time measuring unit 12, and the control unit 14 illustrated in FIG. (Step S23).
The timing unit 12 starts timing after the power-off process is performed (step S24), and when a predetermined time (for example, 10 minutes) has elapsed (step S25: YES), the timing unit 12 notifies the control unit 14 to that effect. Notice.

The control unit 14 that has received the notification from the time measuring unit 12 performs a partial power-on process for resuming the power supply to some of the functional units of the own device (step S26).
After resuming power supply to some of the functional units, the control unit 14 causes the GPS processing unit 7 to perform GPS positioning, and acquires position information indicating the current location of the own device (step S27). Subsequently, the control unit 14 creates an e-mail addressed to a preset e-mail address describing the position information, and transmits the e-mail via the wireless communication unit 5 (step S28).

The control unit 14 returns to step S23 and repeats the operations of step S23 to step S28 shown in FIG.
In step S22, when the flag information is not stored in the storage unit 15, that is, when the emergency mode is not set (step S22: NO), the power-off process is performed as usual (step S29).

The mobile phone 1 with GPS function of this modified example performs the power-off process without acquiring and transmitting the position information when the power button is pressed, and after a predetermined time has elapsed, The process is resumed, and a series of processes of acquiring position information and transmitting an e-mail including the position information is repeated.
The process of this modification takes into account that it takes time for the GPS processing unit 7 to acquire position information. If the time from when the kidnapper presses the power button until the mobile phone 1 with GPS function is turned off becomes longer, it is assumed that the kidnapper is suspicious. The power-off process is performed without acquiring the position information, and then the position information is acquired and transmitted after the partial power-on process for restarting the power supply.
