Description of the Related Art Conventionally, a terminal device is installed at a place where it is used, and the terminal devices installed at a plurality of places are connected to a center device installed at a predetermined place so that each terminal device can A collective karaoke system has been proposed in which karaoke information corresponding to a request is output from a center device only to a requesting terminal device. The center device has a plurality of autochanger players, and stores a lot of music information including video and audio recorded on an optical disc, for example. Further, the terminal device includes an operation unit, a control device, a music information reproducing device for reproducing music information output from the center device, and the like.

By the way, when the requested music does not match the music title, it is necessary to confirm the music before playing the requested music and storing the music number in the storage device in the terminal device. is there. However, in the case of confirming a song by the conventional collective karaoke system, first, the number of the song to be confirmed is input from the terminal device as in the case of a normal request. Then, the music information corresponding to the number is output from the center device to the terminal device, and the music information reproducing device reproduces the music information on the terminal device. Then, when the user performs a cancel operation on the terminal device after confirming the song, the reproduction of the song is stopped. However, when the cancel operation is performed, the music number once stored in the storage device disappears.
Therefore, if the music is the music desired to be requested, the music number is input again and the music is reproduced from the beginning. If the music is different, the above operation is repeated.

As described above, since the conventional collective karaoke system does not have a trial listening function, the user himself / herself performs a trial operation by performing a cancel operation or an operation such as inputting a song number.

Therefore, the present applicant has proposed a collective karaoke system having a listening function that allows a user to easily listen to a desired song (filed on May 26, 1992, reference number 40).
400616, "Aggregate Communication System"). Hereinafter, the collective karaoke system having the conventional audition function will be described with reference to FIG.

FIG. 5 is a block diagram of a main part showing an example of a conventional collective karaoke system having a trial listening function.
In FIG. 1, a conventional collective karaoke system 1 includes a terminal device 2-1 including an operation unit 4, a determination unit 5, a transmission unit 6, an I / F (interface) 7A, a music information reproduction unit 8 and the like.

Each of the terminal devices 2-1 to 2-N has a storage device (not shown) that stores song numbers and the like.

The operation section 4 is a request number (a music number individually attached to music information (music) or a trial listening number corresponding to this music number) composed of numbers and alphabets.
And a display device for displaying the input request number.

The judgment section 5 has a function of judging whether the request number input to the operation section 4 is a normal reproduction request or a trial listening request. As a method of making the judgment unit 5 judge whether it is a normal reproduction request or a trial listening request, there is a method of using a request number which is judged as a trial listening request when a trial listening number set corresponding to an individually assigned music number is inputted. There is also a method of using the audition key for determining that the audition request is made when the audition request signal output by the user pressing the audition key provided separately from the music number key of the operation unit 4 is input. In the case of the former method, the trial listening number is converted into a music number corresponding to the trial listening number and output to the transmitting unit 6. Further, when the request number indicates a trial listening request, the determination unit 5 outputs a stop command signal for stopping the output of the music information signal at a fixed time after outputting the song number, after outputting the song number. When the time has passed, the data is output to the transmission unit 6.

Further, the transmitter 6 outputs the input request number and the terminal number (terminal identification number) of this terminal device as a request signal. In addition, I
/ F7A converts the request signal into a signal system suitable for the transmission line 14 and outputs the signal system to the transmission line 14, and when a signal is input from the transmission line 14, the signal is converted into the music information (voice information). Convert. In addition, the I / F7B

Further, the storage unit 12 stores a large number of optical discs and the like on which a lot of music information such as audio information and video information is recorded, and is also equipped with a plurality of devices for reproducing these. Further, the music information corresponding to the request number is taken out from the optical disc or the like, and the music information transmitting unit 1
Output to 2. The music information reproducing section 8 includes an amplifier for reproducing audio information of the music information transferred from the center device 3, a speaker, headphones, a display device for displaying video information, and a microphone. ..

Next, the operation of the collective karaoke system 1 will be described when a request is made using the terminal device 2-k. In the operation unit 4 of the terminal device 2-k,
When the request number is input, the determining unit 5 determines whether the request number is a normal reproduction request or a trial listening request by the above-described determination method.

When the request number is a request for audition,
When the audition request is made with the audition number, the judging section 5 converts the song number into a music number corresponding to the audition number and outputs this number to the transmitting section 6. Also, when a trial listening request is made with the trial listening key, the inputted song number is output.
Then, the transmitter 6 adds the terminal number to the request number and outputs it as a request signal.
From the center device 3 via the I / F 7A and the transmission path 14 to the center device 3, and the music information corresponding to the request signal is transmitted from the center device 3 to the terminal device 2-k that made the request. Is output to. Then, in the terminal device 2-k, the music information reproducing section 8 starts reproducing the music information.

Then, the judgment unit 5 outputs the request number and outputs the stop command signal again to the transmission unit 6 after a predetermined time has elapsed. The transmission unit 6 outputs the stop command signal to the center device 3 via the I / F 7A and the transmission path 14 in the same manner as the request signal. When this stop command signal is input to the storage unit 12, the music information being reproduced is stopped, and the output of the music information to the music information transmission unit 11 is stopped.
Then, the reproduction of the music information in the music information reproducing section 8 is also stopped. With such an operation, the collective karaoke system 1 can listen to a song by reproducing the first part of the song.

On the other hand, when the request number is a normal reproduction request, the stop signal is not output from the judging section 5 and the requested music piece is reproduced to the end.

[0015]

By the way, according to the above-described collective karaoke system 1, since the number of the music information reproducing section 8 of the terminal device is one, the music information requested by the terminal device is being reproduced. , It is impossible to play other music information at the same time. That is, since the listening cannot be performed while the music information is being played, the listening for the trial must be performed before the next music information is played after the playback of the music information is finished. It's useless.

Therefore, the present invention pays attention to the above points, and even when music information is reproduced in one terminal device,
