The display table 2 is a read-only ROM, the contents of which are preliminarily defined and stored as "tune" for reservation, "tune" for confirmation, and "tune" during performance. There is. The light emitting diode (LED) 19 is arranged behind the character “eye” on the information display board 20.
The other light emitting diodes are omitted. RAM2
Reference numeral 8 denotes a writable and readable FIFO (first in, first out memory) type storage device, which may be included in the karaoke control unit 11.

The requested music pieces are stored in the RAM 28 by numbering them in the order in which they are input. The music piece entered earlier has a smaller number, and the music piece being played is number 1. When the performance is finished, the song is erased and the number of the waiting song is decremented by 1. For example, in FIG. 1, the song number 881 is the first requested song, and the song number 091 is the second requested song. When the confirmation key 29 is pressed and the song number 091 is entered from the ten-key switch 8, the song number display section 21 displays the song number "0901", and the song number display section 6 displays the "02" song.

The karaoke controller 11 includes a separate storage device 9

The V image is combined with the telop of the lyrics character by the image combining circuit 17 and displayed on the display device 15 as a background image. The storage device 9 may be an LD in which not only music / lyrics signals but also background video data are stored at the same time, and a laser player may simultaneously play back music and images. In addition, the singing voice of the singer from the separately provided microphone 18 is converted into the voice synthesizing circuit 1.
At 6, the music is combined with the music of the music signal and broadcast from the speaker 14. The set key 22 in the ten-key switch 8 mainly commands the operation of requesting a music piece, and the ten-key pad is for inputting numerical values. In addition to the song request, the commands include a volume control command for volume, and additional commands for various sound effects such as cheering sound effects such as work and clapping sounds.

The set value input from the ten-key switch 8 is stored in the setting control circuit 34 and controls the operation of the MIDI circuit 10. The set values such as the tempo are displayed on the display 31 after the input is confirmed. The numerical code from the numeric keypad is decoded by the CPU 5, and the numeral is displayed on the music number display section 21 such as a liquid crystal display.

When the CPU 5 receives an input signal from the set key 22 on the ten-key switch 8, it outputs a lighting pulse to the LED driver 7. The LED driver 7 causes the light emitting diode 19 to emit light or blink according to the lighting pulse. Once the LED driver 7 receives the turn-on pulse, it keeps that state and keeps the light-emitting diode 19 emitting light until the turn-off pulse comes. Further, when the CPU 5 receives an input signal from the performance start key 25, it outputs an extinguishing pulse to the LED driver 7. The LED driver 7 turns off the light emitting diode 19 according to the turn-off pulse. Once the LED driver 7 receives the turn-off pulse, it keeps that state and keeps turning off the light emitting diode 19 until the turn-on pulse comes.

That is, when the CPU 5 receives an input signal from the set key 22 on the ten-key switch 8, it recognizes that it is a song reservation, selects the "tune" of the ROM 2 reservation, and sends a lighting pulse to the LED driver 7. Output. In the case of request confirmation, since an input signal from the confirmation key 29 is generated, it is recognized that the confirmation is a tune, the "tune" of confirmation in the ROM 2 is selected, and a lighting pulse is output to the LED driver 7.

Further, when the CPU 5 receives an input signal from the performance start key 25, it recognizes that the performance operation is started and selects the "song" being played, and therefore outputs an extinguishing pulse to the LED driver 7.

Next, the operation of the CPU 5 of the karaoke control section 11 will be described with reference to the flowchart of FIG. The power is turned on and the flow starts. In step S1, C
The PU 5 checks whether or not there is a reception from the set key 22, and if there is a reception, it goes to step S4 and turns on the LED 19. Then, the "eyes" of the music number display portion 6 are raised by the light, the characters are combined with the "music" originally displayed by the light of another LED, and the "music" is displayed as shown in FIG. Therefore, at the time of reservation input, what “tune” of the reservation is displayed.

In step S1, if there is no reception from the set key 22, the process proceeds to step S2, and the CPU 5 checks whether or not there is a reception from the confirmation key 29. If there is reception, the process proceeds to step S4 to turn on the LED 19. Therefore, when confirming the reservation, the reservation confirmation operation is performed when the number of reserved "songs" is displayed to display what the "song" is.

In step S2, if there is no reception from the confirmation key 29, the process proceeds to step S3, and the CPU 5 checks whether or not there is reception from the performance start key 25. If there is reception, the process proceeds to step S5 to turn off the LED 19. Then, the "eyes" of the music number display portion 6 disappear, and only the "music" originally displayed by the light of another LED is displayed as the "music" as shown in FIG. Therefore, at the time of performance, reserved "song"
Display the number.

If there is no reception from the performance start key 25 in step S3, the process returns to step S1 to wait for the next command. By selectively turning on or off the "eye" of the characters "tune" after the numeral portion 28 of the music number display portion 6,
It is possible to display two types of information on the display section at some places. The present invention can also be applied to the case of a communication karaoke device that receives music data from a remote host database.
