FIG. 6 is a block diagram of a simple configuration of folding portable telephone apparatus according to an embodiment of the invention. In FIG. 6, radio waves coming from an antenna 20 are received by the receiver (not shown) of a radio communications section 21 and received information is transferred to a controller 22. The controller 22 displays the received information such as telephone numbers on the first display 4 on the outer surface of the main body or on the second display 8 on the inner surface of the main body.
The controller 22 converts received information to voice information and outputs the voice information from a receiver (speaker) 23. The transmitter (microphone) 24 transfers the user's voice to the controller 22 and transmits the information to the distant party via a transmitter (not shown) of the radio communications section 21 and the antenna 20. A key operation area 26 composed of a ten-digit keypad and a scroll key is adapted to input signals to the controller 22 via key operation and to store telephone number information, etc. in the memory 25 via the controller 22.
Folding/unfolding state detector 27 on the main body detects the folding/unfolding state of the main body and communicates the result to the controller 22. The controller for a pocket game 28 comprises game programs and a CPU, and displays the pocket game playing state on the first display 4 on the outer surface of the first case body, via input operation from the key operation area 26 on the outer surface of the first case body.
The controller for a pocket game 28 suspends the operation of the game when the controller for a pocket game 28 receives a suspend instruction from the controller 22. An earphone microphone jack 37 is adapted to connect an earphone microphone 37 having an earphone 33 and a microphone 34 to the controller 22 so that the user can hear the sound of a pocket game with the main body folded and input a voice command.
FIG. 7 is a flowchart showing the operation in which folding portable telephone apparatus according to the first aspect of the invention starts a call from the call incoming wait state irrespective of whether the main body is folded or unfolded. With the folding portable telephone apparatus powered on and in the call incoming wait state (step 1), when there is a incoming call (step 2), ringing starts or a call incoming indicator or a backlight on the display blinks (step 7).
The controller 22 obtains folding/unfolding state information from the cover opening/closing state detector 27 and determines whether the body is folded or unfolded (step 4). When the body is folded, the controller 22 displays caller information, i.e., the telephone number of the caller or caller's name on the first display 4 on the outer surface of the folded main body (step 5). When the user presses the call start button 5a (step 6), the user starts conversation using the earphone microphone 36 connected to the earphone jack 37 (step 7).
When the body is unfolded, caller information is displayed on the second display 8 on the inner surface of the main body (step 8). When a call start key 12a is pressed (step 9), the folding portable telephone apparatus starts a call by using the receiver 23 and the transmitter 24. Thus, according to the invention, the user can start conversation when the incoming call, irrespective of whether the main body is folded or unfolded.
With the main body folded, the user cannot directly enter a telephone number using the ten-digit keypad 10. As shown in the flowchart of FIG. 8, the user can register telephone numbers as a telephone directory in a memory 25 and scroll through and display the telephone numbers by using the navigation key 7 which is a scroll key, then press the call start button 5a to start call origination.
FIG. 9 is a flowchart showing the operation in which folding portable telephone apparatus according to the invention which can be used as typical portable telephone apparatus as mentioned earlier is used as a pocket game machine. When the folding portable telephone apparatus is powered on, the apparatus enters the call incoming wait state (step 21). When the start button 5a on the outer surface of the first case body (step 22), the controller for a pocket game 28 is activated and the pocket game starts (step 23). The user plays the game by using the A button 6, B button 5a and the navigation key 7 to play the game while hearing the sound of the pocket game via the earphone microphone provided on the side of the main body. The pocket game continues as long as no incoming call.
When there is an incoming call (step 24), the controller 22 issues a suspend instruction to the controller for a pocket game 28 and displays caller information, i.e., the telephone number of the caller or caller's name on the first display 4 which displayed the game in progress until then. The user checks the caller information. When the user presses the call start button 5a (step 26), the user starts conversation using the earphone microphone 36.
When the call release button 5b is pressed (step 28), the call is released (step 29). Because the pocket game is only suspended, when the start button 5b is pressed instantaneously for a short period (step 30), the pocket game restarts (step 34). When the game is over (step 35), the pocket game ends and the apparatus returns to the call incoming wait state again (step 36).
Even in case there is an incoming call and the caller information is displayed (step 25), when the call start button 5a is not pressed (step 26) but the start button for a pocket game 5b is pressed (step 32), a message stored in the memory 25 in advance, for example, a message “Sorry. The party at this number is not available now. Please use the automatic recording service.” is sent (step 33) to release the call and restart the game (step 34). When the game is over (step 35), the pocket game ends and the apparatus returns to the call incoming wait state again (step 36).
FIG. 10 is a flowchart showing the operation in which folding portable telephone apparatus according to the second embodiment of the invention is used as a pocket game machine. FIG. 10 differs from FIG. 9 in that, when an incoming call (step 44), the call incoming indicator or the backlight on the display blinks or ringing starts as a call incoming display, without forcibly suspending the pocket game as in step 25 in FIG. 9, and the user is asked for some operation (step 45).
When the user unfolds the main body at the right time in the proceeding of the pocket game, the folding/unfolding state detector 27 detects that the main body is open (step 46). The controller 22 issues a suspend instruction to the controller for a pocket game 28 to suspend the game and displays caller information on the second display 8 (step 47). When the user presses the call start key 12a (step 48), the user starts conversation using the transmitter 15 and the receiver 16 (step 49).
When the call release button 5b is pressed (step 50), the call is released. When the folding/unfolding state detector 27 detects that the main body is open, it may be assumed that the call start key 12a is pressed and step 48 maybe omitted. When the folding/unfolding state detector 27 detects that the main body is folded, it may be assumed that the call release key 12b in step 50 is pressed.
Even in case the call is released in step 51 and the main body is folded, the pocket game is only suspended. When the start button 5b is pressed instantaneously for a short period (step 52), the pocket game restarts (step 56). When the game is over (step 57), the pocket game ends and the apparatus returns to the call incoming wait state again (step 58). The remaining procedures are omitted because they are the same as the flowchart in FIG. 9.
