Output to (17).

If the chorus data for the song selected by the user exists, the chorus data is output from the magnetic storage medium 13 to the audio signal processor 15 under the control of the magnetic storage medium control unit 14 and converted into an audio signal before the signal. It is output to the combiner 17.

The signal synthesizing unit 17 synthesizes a voice signal of a user input through a musical instrument, a chorus sound, and a microphone and outputs the audio signal to the audio amplifier.

In addition, the caption data or related image data of the song selected by the user is converted into a video signal through the caption / image processing unit 18 and output to the monitor.

In this case, the related video may be input from an external image output device in addition to the magnetic storage medium 13, and in this case, the video may be received as an input.

However, in the conventional song accompaniment apparatus having the above-described configuration and operation, the following problems may occur due to storing not only chorus data but also song accompaniment data on a hard disk having a sufficient capacity.

That is, if the song accompaniment device is frequently used for a long time, the song accompaniment device must continuously read the hard disk in order to output a large amount of chorus data corresponding to the song selected by the user. This can cause the hard disk to malfunction or not work.

In this case, the song accompaniment data and the like cannot be read, and eventually the entire song accompaniment device becomes unusable.

Therefore, an object of the present invention is to store chorus data occupying a large data capacity in a song accommodating device separately from song accompaniment data by using a separate storage medium, even if the chorus data storage medium malfunctions or does not operate. The song accommodating device provides a song accommodating device having a memory for storing chorus data that can be normally operated.
