The process ends (step S22).

Next, referring to the flowchart of Fig. 3, the operation of conducting a call by telephone number provided from a radio station will be described in detail.

First, in a state in which a broadcast program of a specific radio broadcast frequency channel tuned from the tuner 10 is being reproduced (step S30), the control unit 40 uses the additional information extraction unit 42 to output a radio broadcast signal from a radio station. It is judged whether or not the broadcasting station telephone number information data additionally inserted into the terminal is extracted (step S31).

As a result of the determination, when it is determined that the phone number information data of the radio station has been extracted by the additional information extracting unit 42, the control unit 40 stores the phone number information data provided from the additional information extracting unit 42. It is stored in the data storage space of (step S32).

In this state, the control section 40 determines whether or not the broadcast station call mode is set by the one-key operation by the user operation of the function input section 36 (step S33).

As a result of the determination, when the function input unit 36 is one-key operated and it is determined that the broadcasting station call mode is set, the control unit 40 performs automatic dialing by the dialing circuit 28 according to the previously stored broadcasting station telephone number information data. The call connection for participation in the currently broadcast radio broadcast program is attempted (step S34).

Accordingly, the controller 40 determines whether a call connection is made with the radio station (step S36), and if it is determined that a call connection is not made with the corresponding radio station side, the user controls the function input unit 36. It is determined whether or not the call connection attempt is canceled by step S36.

In the result of the determination of step S36, when it is determined that the call connection attempt is canceled by the user operation of the function input unit 36, the controller 40 controls the call connection unit 26 to perform the call connection attempt. It cancels (step S37).

However, according to the determination result of step S35, when it is determined that the call connection is made with the radio broadcasting station side, the control unit 40 mutes the audio signal processing operation of the audio signal processing unit 20 to Instead of preventing the audio output from being reproduced and output through the speaker 24, normal voice call with the person in charge of the corresponding radio broadcasting program is possible through the call / signal voice signal processing by the call voice processor 32 (step S38). ).

Then, the control section 40 determines whether or not to perform the operation for releasing the call connection by the user's manipulation of the function input section 36 (step S39).

As a result of the determination, if it is determined that the user is releasing the call connection through the operation of the function input unit 36, the controller 40 controls the call connection unit 26 to release the call connection and the audio signal processing unit 20. The muting state is released to switch to the normal playback state of the radio broadcast (step S40).
