There is no switching to another input source such as a tuner. Further, when the switching amplifier 2 is set to the audio priority mode, when the reading audio signal is input, the audio selector 21 and the video selector 23 of the switching amplifier 2 are switched to another input source. However, if the reading is a narration with a pause, then the voice selector 21
And the video selector 23 may be switched to another source. However, in this embodiment, since the inaudible sound is always generated and input to the switching amplifier 2 as described above, the audio selector 21 and the video selector 23 are always set to the music playing apparatus 1 side.

In this embodiment, when the reading data is reproduced, the sound source 16 synthesizes the non-audible sound and the switching amplifier 2
And the pattern generation unit 19 generates a plain video signal and outputs it to the switching amplifier 2. However, it is determined whether the selector of the switching amplifier is in the audio priority mode or the video priority mode, In the audio priority mode, only the non-audible sound is synthesized and no solid video signal is generated, and in the video priority mode, only the solid video signal is generated and the non-audible sound is not synthesized. Thus, the object of the present invention can be achieved.
