FIG. 4 is a flowchart showing cellular phone processing performed in a cellular phone with a personal computer function.
First, when the power is turned on, the microcomputer 30 reads the portable OS stored in the nonvolatile memory 28, and then executes a program execution process on the OS (step S10). In this processing, the microcomputer 30 executes processing related to incoming calls and calls, processing related to mail transmission / reception, and the like based on a predetermined program.

Next, the microcomputer 30 determines whether or not the external device 50 is connected (step S11). If it is determined that the external device 50 is not connected, the process returns to step S10. On the other hand, if it is determined that the external device 50 is connected, the process proceeds to step S12.

In step S12, the microcomputer 30 performs connection processing. Although details will be described later with reference to FIG. 5, in this process, the microcomputer 30 restarts and switches the OS from the portable OS to the OS for PC. Accordingly, it is possible to perform input / output of signals and transmission / reception of data to / from various devices included in the external device 50 via the connection terminal 34. Therefore, for example, instructions, characters, and the like can be input from the keyboard 64 provided in the external device 50, and a screen image or other image to be displayed on the liquid crystal panel 14 can be displayed on the display device 66. Thereafter, the process proceeds to step S13.

In step S13, the microcomputer 30 performs a program execution process on the PC OS. In this process, the microcomputer 30 executes a process related to a function as a personal computer. At this time, the microcomputer 30 executes a process for maintaining the waiting state for the incoming call in parallel.

Next, in step S <b> 14, the microcomputer 30 determines whether to disconnect the connection with the external device 50. In this process, the microcomputer 30 determines whether or not an instruction input for disconnection has been made by the user. When it is determined that the connection with the external device 50 is to be disconnected, the microcomputer 30 executes a disconnection process (step S15). Although details will be described later with reference to FIG. 6, in this process, the microcomputer 30 restarts and switches the OS from the PC OS to the portable OS. Thereafter, the process proceeds to step S10.

If it is determined in step S14 that the connection with the external device 50 is not disconnected, the microcomputer 30 determines whether there is an incoming call (step S16). When this process is executed, the microcomputer 30 functions as an incoming call detection means for detecting an incoming call.

If it is determined in step S16 that there is no incoming call, the process returns to step S13. On the other hand, if it is determined that there is an incoming call, the microcomputer 30 executes an incoming call process (step S17). Although details will be described later with reference to FIG. 7, in this process, the microcomputer 30 restarts and switches the OS from the PC OS to the portable OS, and then notifies the incoming call. After the process of step S17, the process returns to step S10.

FIG. 5 is a flowchart showing a subroutine of processing at the time of connection performed in the mobile phone with a personal computer function.
First, the microcomputer 30 ends the program execution process based on the portable OS (step S20) and turns off the power (step S21). At this time, the microcomputer 30 is set to read the PC OS from the hard disk drive 58 of the external device 50 when the power is turned on. Specifically, a setting is made so that a predetermined bias value is applied to the segment base of each descriptor of the GDT (global descriptor table) stored in the nonvolatile memory 28, and the hard disk drive 58 of the external device 50 is turned on when the power is turned on. The OS for PC is read from. In this embodiment, a case where the OS is switched by restarting will be described, but the OS switching method is not limited to this example.
In the present embodiment, a case where the power is turned off and the OS is switched will be described. However, the present invention is not limited to this example, and after the running OS is terminated without turning off the power, The OS may be switched by reading another OS.

In step S22, the microcomputer 30 is turned on again and started. Next, the microcomputer 30 reads the PC OS from the hard disk drive 58 of the external device 50 according to the setting at the time of power-off (step S23), and starts execution of a program based on the PC OS (step S24). Thereby, the mobile phone 10 functions as a personal computer integrated with the external device 50. After the process of step S24, this subroutine is terminated.

FIG. 6 is a flowchart showing a subroutine for processing at the time of disconnection performed in the mobile phone with a personal computer function.
First, the microcomputer 30 ends the program execution process based on the PC OS (step S30), and turns off the power (step S31). At this time, the microcomputer 30 is set to read the portable OS from the nonvolatile memory 28 when the power is turned on.

Next, in step S32, the microcomputer 30 is turned on again and started. Next, the microcomputer 30 reads the portable OS from the hard disk drive 58 of the external device 50 in accordance with the setting when the power is turned off (step S33), and starts the execution processing of the program based on the portable OS (step S34). After the process of step S34, this subroutine is terminated.

FIG. 7 is a flowchart showing a subroutine of processing at the time of incoming call performed in the mobile phone with the personal computer function.
First, the microcomputer 30 interrupts the program execution process based on the PC OS (step S40), and stores the operating environment of the PC OS in the nonvolatile memory 28 in the interrupted state (step S41). Therefore, next time when the PC OS is activated (step S12), the operation environment is read out, and the program execution is resumed in the operation environment stored in step S41. When executing the processing of step S40 and step S41, the microcomputer 30 functions as a saving processing means for performing processing for saving the operating environment to the nonvolatile memory 28 when the incoming call is detected.

Next, in step S42, the microcomputer 30 turns off the power. At this time, the microcomputer 30 is set to read the portable OS from the nonvolatile memory 28 when the power is turned on.

Next, in step S43, the microcomputer 30 is turned on again and started. Next, the microcomputer 30 reads the portable OS from the non-volatile memory 28 according to the setting at the time of power-off (step S44), and starts execution of a program based on the portable OS (step S45). When executing the processes of steps S44 and S45, the microcomputer 30 functions as a switching means for switching the personal computer OS to the mobile phone OS.

Next, in step S46, the microcomputer 30 outputs a sound from the incoming call notification speaker 36, performs control to display an image or a moving image on the liquid crystal panel 14, notifies the incoming call, and ends this subroutine.

FIG. 8 is a flowchart showing a subroutine of power management processing performed in the mobile phone with a personal computer function. This subroutine is called and executed at a predetermined timing separately from the subroutine shown in FIG.

First, the microcomputer 30 determines whether or not the external device 50 is connected (step S70). If it is determined that the external device 50 is not connected, the microcomputer 30 determines whether or not the AC adapter 36 is connected (step S71). If the AC adapter 36 is not connected (step S71: NO) ), The power management function is executed (step S72), and this subroutine is terminated.

On the other hand, when it is determined that the external device 50 is not connected (step S70: NO), or when it is determined that the AC adapter 36 is connected (step S71: YES), the microcomputer 30 has a power management function. Is disabled (step S73), and this subroutine is terminated.

As described above, according to the mobile phone 10 according to the present embodiment, execution of a program is controlled based on the PC OS stored in the external device 50 in a state connected to the external device 50. Then, when the incoming call is detected, the PC OS operating environment controlled by the microcomputer 30 is saved in the nonvolatile memory 28. When the saving process is completed, the PC OS is activated. Switching to the portable OS, the incoming call is notified when the switching is completed. That is, even when there is an incoming call when connected to the external device 50 and used as a personal computer, the user is inadvertently removed because the incoming call is notified after the operating environment is saved. Can be avoided. In addition, since the incoming call is notified after the operating environment is evacuated, the user can make a call without worrying about the situation that the data created before the incoming call is lost. . In addition, since the incoming call is notified when the switching from the PC OS to the portable OS is completed, it can be removed from the external device 50.
Further, since the operating environment before the incoming call is saved, it is possible to start the work from the state before the incoming call by connecting to the external device 50 again after the call.
