Thereby, the communication operation can be performed whether the housing is open or closed.

In the foldable portable communication device 1 according to the present embodiment, the CPU 110 controls the first display 17 when the first and second housings 11 and 12 are open. In the case where the first and second housings 11 and 12 are closed, a character or an image is displayed on the second display 21 to notify that the communication operation is being performed. The first and second indicators 17 and 21 may be controlled so as to perform the operations. As a result, it is possible to recognize on the display screen whether or not communication is being executed, and it is possible to prevent forgetting to disconnect the communication.

An example of the operation of the foldable portable communication apparatus according to the present embodiment having the above-described configuration will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. In the figure, when the power of the foldable portable communication device 1 is turned on, a standby state is set (step 500), and then whether or not the foldable portable communication device 1 is in the folded state, that is, the first and second two It is determined whether the two housings 11 and 12 are in a closed state based on the detection output of the open / close sensor 119 (step 501). If the determination in step 501 is negative, that is, if the two housings 11 and 12 of the foldable portable communication device 1 are in an open state,
Switch to data communication mode (step 50)
5).

On the other hand, when the determination in step 501 is affirmative, that is, when the folding portable communication device 1
When the two housings 11 and 12 are in the closed state,
The call operation start / stop function and the reception operation start / stop function are assigned to the operation keys 19 (step 502), and then the telephone number calling function is assigned to the second operation keys 20 (step 503). Further, in step 504,
The first display 17 is set to the non-operation state, and the second display 21 is set to the operation state. Next, at step 506, it is determined whether or not there is an incoming call.

If it is determined in step 506 that there is an incoming call, the telephone number of the called party is displayed on the second display 21 (step 507), and then the first operation key 19 is operated. As a result, the incoming call operation is activated (step 510), and the operation shifts to voice communication (step 51).
1). On the other hand, if it is determined in step 506 that there is no incoming call, it is determined in step 508 whether or not the second operation key 20 has been operated.

If the determination in step 508 is denied, the process returns to step 500 and enters a standby state. If the determination in step 508 is affirmative, the telephone number read by the telephone number calling function is displayed on the second display 21 (step 509). Further, when the first operation key 19 is operated in step 510 and a call is made, the flow shifts to voice communication (step 511).

Next, the processing contents in the data communication mode executed in step 505 in FIG. 5 are shown in the flowchart of FIG. In FIG. 6, when the operation mode is switched to the data communication mode, first, the second display 2
1 is turned off, the first display 17 is turned on (step 600), and then a telephone number and character input function, a call operation function, a call operation function, and a telephone number registration are entered on the keypad 18. A function such as an operation function is assigned (step 601). Further, in step 602, the data rate is set so as to be a data rate suitable for data communication, and the process shifts to data communication (step 603).

Next, FIG. 7 shows the processing contents of the voice communication executed in step 511 in FIG. In FIG. 7, the mode is shifted to the voice communication mode, voice communication is executed (step 700), and then it is determined whether or not the first operation key 19 is operated (step 701). If it is determined in step 701 that the first operation key 19 has not been operated, the process returns to step 700 to continue voice communication. In step 701, the first operation key 1
If it is determined that No. 9 has been operated, a call disconnection process is performed (step 702), a transition is made to a standby state (step 703), and voice communication is terminated.
