Therefore, the wiring of the video cable between the control device 30 and each monitor can be re-wired, or the video can be re-wired. The video displayed on the monitor 20 and the monitor 22 can be switched without adding an output system. In particular, the monitor 22 used by the singer on the stage for monitoring has a smaller screen than the monitor 20. Therefore, if the same synthetic image as the monitor 20 is displayed, the lyrics in the subtitle image may be difficult to read. Since only images relating to karaoke can be displayed on 20, the singer does not have to worry.

Further, in the video processing circuit 39 of the control device 30, there is provided a judgment changing circuit 39d for changing the judgment result of the CPU 37a. This judgment changing circuit 39d.

By operating d, it is possible to change to a determination result different from the above determination result, for example, a determination result in which the monitor 22 displays the same image as the monitor 20.

Thus, for example, when an emergency call is made during karaoke or an emergency image such as a fire is sent from the store side, the content is displayed on the monitor 22. You can also inform the singer. In the above embodiment, the case where the number of monitors is two has been described. However, assuming that three or more monitors are connected in advance, the total value of the input impedance of the monitors for each number is calculated, and the total value is calculated. The detection signal corresponding to the value (for example, a signal obtained by changing the duty ratio of the pulse signal) is output from the resistance detection circuit 24, and the control content of the CPU 37a is controlled by the form and size (for example, the duty ratio) of the detection signal. Can be changed.

Further, in the above embodiment, the connection state detecting means determines the number of monitors connected based on the input impedance of the monitor. However, it is turned on by inserting a pin plug into each video output terminal of the control device. It is also possible to provide a micro switch for turning off and determine the number of connected monitors by the number of the switches. Further, by connecting the video output of the TV tuner to the information video signal code 81, a normal TV broadcast can be displayed on the screens of the monitors 20 and 22 alone or in a divided manner.

Further, the information video data storage section 84
It is also possible to store a message from a store where the karaoke device 10 is installed, for example, data such as time extension fee, new song information, food and drink menu, and display it on the screen of the monitor 20. In this case, the information video data memory area 38c may be formed in the hard disk memory 38 (see FIG. 3), and the information on the store side may be stored in the area. Further, when a scoring device for scoring singing ability is provided, the scoring result can be displayed as one of the information images.

The musical sound reproducing apparatus of the present invention can be applied to a karaoke apparatus for performing karaoke using an LD player for reproducing a disc storing both music data and background data, and of course, does not perform karaoke. It can also be applied to (audio & visual) devices.
