It is realized the media.

Next, the essential points of the operation of the handset C having the above configuration will be described with reference to the flowchart shown in FIG.

FIG. 3 is a flowchart showing an operation procedure of the call waiting process by the handset C. As shown in FIG. 3, first, the CPU 1 performs a call process with one other party. (S1). In this call processing, it is assumed that the input and output levels of the sound input unit 11 and the sound output unit 12 are in the normal state, and the call is being performed in the normal call mode.

Then, the CPU 1 determines whether or not a call signal from another caller is received via the radio unit 15 during a call with one other party (S2), and the call signal is received. If this is the case (S2: YES), the CPU 1 determines whether or not caller information relating to the telephone number of the caller is added to the received call signal (S3).

When the caller information is added to the caller information (S3: YES), the CPU 1 displays the received caller telephone number on the display panel C4 (S4).

At almost the same time as displaying the source telephone number,
The CPU 1 switches from the normal call mode via the sound input unit 11 and the sound output unit 12 to the hands-free call mode (S5). In other words, in a call with one other party, a call is made by voice with the handset C placed close to the ear. During the call, a call signal is received from another caller, and the caller's call is received. Phone number is display panel C4
Is displayed, the input / output level is increased at the same time, and the mode is switched to a hands-free call in which a call can be made even at a position away from the handset C. Thus, it is possible to visually confirm and confirm the telephone number of the caller displayed on the display panel C4 while talking with the other party while the handset C is kept away from the ear. When switching to such a hands-free call, the input and output levels of the speaker and the microphone are not changed to a predetermined value at once, but are changed gradually.

After switching to the hands-free call mode,
The CPU 1 determines whether the hands-free switch C3b has been pressed by a user operation (S6), and the hands-free switch C3b is not pressed (S6: N).
O), when the catch button C3c is pressed by the user's operation (S7: YES), the CPU 1 switches from the hands-free call mode to the normal call mode (S7).
8).

Almost simultaneously with the operation of S8, the CPU 1
Switches the call partner in the call process to the call source received from one contact (S9). That is, after confirming the telephone number of the caller, the call partner is switched by operating the catch button C3c.

The call processing with the caller is completed by closing the line or the like, and the catch button C is again operated by the user.
When 3c is pressed (S10: YES), the CPU 1
Perform call processing with the other party that was in the first call (S
11) After that, the line is closed and the routine is terminated.

If the catch button C3c is not pressed in S10 (S10: NO), the CPU 1 proceeds to S9
Return to and continue the call processing with the caller.

In S7, if the catch button C3c is not pressed (S10: NO), the CPU 1 returns to S6 and repeatedly executes a process for determining whether or not the hands-free switch C3b is pressed.

In S6, the hands-free switch C3
If b is pressed (S6: YES), the CPU 1 proceeds to S
Returning to step 1, the communication process with the other party in the normal call mode is executed.

If no caller information is added to the call signal in S3 (S3: NO), the CPU 1 determines whether or not the catch button C3c is pressed by a user operation (S12). When C3c is pressed (S12: YES), the CPU 1 executes a series of operations from S9. In other words, when the calling telephone number is not added to the calling signal and only the ringing tone is output, the calling telephone number is not displayed on the display panel C4, and the call is switched to the hands-free call. The call partner can be switched to the caller in the normal call mode without any problem.

If the catch button C3c is not depressed in S12 (S12: NO), the CPU 1 proceeds to S1
And returns to the normal call mode to execute a call process with one other party.

In S2, when the call signal is not received (S2: NO), the CPU 1 returns to S1 and executes a communication process with one other party in a normal communication mode.

Therefore, according to the telephone provided with the handset C having the above configuration and operation, when a call signal from another caller is received during a call with one party via the handset C, A display panel C4 provided in the handset C
The telephone number of the caller is displayed on the
At the same time. In other words, the display panel C4 provided on the handset C must be in a posture in which it can be visually recognized in order to confirm the source telephone number. At this time, the input / output level of the handset C is simultaneously increased, Since a so-called hands-free call function is exhibited, the handset C can be temporarily separated from the ear and the display panel C4 can be viewed while maintaining a call state with the other party, without requiring any switching operation. The telephone number of the caller who has received the telephone call with the other party can be confirmed by the display panel C4.

In the present embodiment, the handset C used as a handset phone has the above-described functions. However, such a function may be provided in the telephone body A. In this case, the telephone main body A wirelessly controls various operations of the handset C.

Further, the handset C is provided with a speaker for outputting voice from the other party, but another speaker for outputting a large volume is provided outside the gripping portion of the handset C, and the hand is provided. When a free call is performed, a configuration may be adopted in which sound is output via a speaker for outputting a large volume.
