[0011]
A CPU (Central Processing Unit) 11 performs various control operations in accordance with various processing programs for mobile terminals stored in the storage device 15 in accordance with instructions input from the input unit 12 and the wireless communication control unit 14. Specifically, the CPU 11 executes a media non-insertion notification process described later.
[0012]
The CPU 11 receives a signal indicating whether or not the external recording medium M is loaded from the I / F 18 and stores the attachment / detachment state of the external recording medium M in a media flag in the storage device 16 based on this input signal. The media flag is a flag indicating the attachment / detachment state of the external recording medium M, and the CPU 11 sets “1” if the external recording medium M is inserted in the mobile terminal device 1 and “0” if it is not inserted. .
[0013]
In the media non-insertion notification process, the CPU 11 receives a signal indicating that the cellular phone 1 has been disconnected from the charger 2 from the charging terminal 19 or when the cellular phone 1 is switched from OFF to ON. Further, referring to the media flag, if the media flag is “0”, it is notified that the external recording medium M has not been inserted.
[0014]
If the CPU 11 determines that the mobile phone 1 is disconnected from the charger 2 based on the input signal from the I / F 18 in the media non-insertion notification process, the power control is performed if the power of the mobile phone 1 is OFF. The unit 20 is controlled and switched to ON. Thereby, it is possible to notify that the external recording device is not inserted using the display unit 13 and the transmission / reception unit 17.

[0025]
The external recording medium M is a recording medium that can be attached to and detached from the mobile phone 1. As the external recording medium M, for example, a SIM (Subscriber Identity Module) card in which information related to the user, a telephone book having a plurality of telephone numbers, personal identification information for credit settlement, and the like can be used. In addition, a USIM (Universal Subscriber Identity Module) card, a UIM (User Identity Module) card, or the like can also be used.
[0026]
Next, the operation will be described.
FIG. 2 is a flowchart showing media non-insertion notification processing. As shown in FIG. 2, based on the input signal from the charging terminal 19, the CPU 11 determines whether or not the mobile phone 1 is disconnected from the charger 2 and charging is interrupted (step S1).
[0027]
If charging is not interrupted (step S1; NO), it is determined whether or not an instruction to switch the power supply from OFF to ON is input from the input unit 12 (step S2). If there is no input (step S2; NO) Returning to step S1, when an instruction to turn on the power is input (step S2; YES), the power supply control unit 20 switches on the power (step S4).
[0028]
On the other hand, when the CPU 11 determines that the charging is interrupted in step S1 (step S1; YES), the CPU 11 determines whether or not the power is OFF (step S3), and if the power is OFF (step S3; YES). ) The power supply control unit 20 switches on the power (step S4), and the process proceeds to step S5. If the power is turned on in step S3 (step S3; NO), the process proceeds to step S5 as it is.
[0029]
Next, the CPU 11 refers to the media flag stored in the storage device 16 and determines whether or not the external recording medium M is inserted (step S5). When the media flag is “1”, that is, when the external recording medium M is inserted (step S5; YES), the CPU 11 ends the media non-insertion notification process as it is. On the other hand, when the media flag is “0”, that is, when the external recording medium M is not inserted (step S5; NO), the LED of the display unit 13 is turned on, and the external recording medium M is not displayed on the display unit 13. A message indicating insertion is displayed, and a warning sound is generated from the transmitter / receiver 17 (step S6).
[0030]
Next, the CPU 11 monitors the change in the input signal from the I / F 18 (step S7). If there is no change in the input signal from the I / F 18 (step S7; NO), the CPU 11 continues to stand by and determines that the external recording medium M has been inserted due to the change in the input signal from the I / F 18 (step S7). (S7; YES), the media flag of the storage device 16 is set to “1” (step S8), the notification by the display unit 13 and the transmission / reception unit 17 is terminated (step S9), and the media non-insertion notification process is terminated. .
[0031]
As described above, the CPU 11 of the portable terminal 1 stores the attachment / detachment state in the media flag in the storage device 16 every time the external recording medium M is attached / detached. Further, in the media non-insertion notification process, the CPU 11 sets the media flag when the mobile phone 1 is disconnected from the charger 2 or when an instruction to switch the power supply from OFF to ON is input via the input unit 12. If the external recording medium M is not inserted into the mobile phone 1 with reference to it, it is notified that it has not been inserted.
[0032]
Therefore, according to the present invention, even when the power of the portable terminal is OFF, the notification can be made by turning on the power if the external recording medium is not inserted. This prevents the portable terminal from being carried without an external recording terminal, and can be used without restricting the functions of the portable terminal even when away from home.
[0033]
