Subsequently, at step 12, it is determined whether or not the simultaneous play mode has been set, and when it is determined that the simultaneous play mode has been set, the routine proceeds to step 13, where the simultaneous play mode is set. Release and set to normal play mode, then step 1
4. Simultaneous button is turned off (indicator is off)
Then, after notifying the user of the normal play mode, the process returns to step 1 to wait for the next button operation.

That is, when the user selects a visual source and the simultaneous play mode is set, the process is performed so that the simultaneous play mode is automatically canceled regardless of the simultaneous button on the front panel. It is.

When it is determined in step 12 that the simultaneous play mode is not set, that is, when it is determined that the normal play mode is set, the processing of steps 13 and 14 is omitted. .

On the other hand, step 9 (the processing flow of FIG. 4)
When it is determined that the user's button operation does not instruct the selection of the visual source, the
Proceeding to (the processing flow of FIG. 5), it is determined whether or not the user's button operation instructs selection of an audio source. That is, it is determined whether the FM button, AM button, CD button, or MD button provided on the front panel has been operated.

When it is determined that the user's button operation instructs the selection of the audio source by the determination processing in step 15, the process proceeds to step 16 to determine whether or not the simultaneous play mode is set. When it is determined that the simultaneous play mode has been set, the process proceeds to step 17, where the second switch circuit 7 controls the selected audio source to select the selected audio source. After controlling the sound of the audio source to be output to the speaker 3,
The process returns to step 1 to wait for the next button operation.

That is, when the user selects an audio source and the simultaneous play mode is set, the sound of the selected audio source is output to the speaker 3 regardless of the visual source image output to the monitor 2. Is output to

On the other hand, when it is determined that the simultaneous play mode has not been set by the determination processing of step 16, that is, to determine that the normal play mode has been set, the process proceeds to step 18 and the visual Determine whether the source video is being output,
When it is determined that the image of the visual source is being output, the process returns to step 1 to wait for the next button operation without performing any processing on the second switch circuit 7.

That is, when a user selects an audio source and is outputting a video of a visual source while following the normal play mode, the selection of the audio source is ignored, and the sound of the output visual source is ignored. The data is output to the speaker 3 as it is.

On the other hand, when it is determined in step 18 that the video of the visual source is not being output, the process proceeds to step 19 (the processing flow of FIG. 6).
By controlling the second switch circuit 7 to select the selected audio source, the sound of the selected audio source is controlled to be output to the speaker 3 and then the next button operation is waited. Return to step 1 in order.

That is, when the user selects an audio source, if only the sound of the audio source is being output in accordance with the normal play mode, the sound of the selected audio source is output to the speaker 3. .
