Next, the operation of the above karaoke reproducing apparatus will be described. When a disc is newly stored in the disc storage portion 2 of the autochanger 1, the installation operation is first performed. In this installation operation, the system controller 7 stores a new disc in the disc storage portion 2 as shown in FIG. 4, and when it detects it (step S1), mounts the disc on the turntable of the player portion 4. Disc transport unit 3
To the disk set command (step S
2). When the disc transport unit 3 finishes mounting the disc on the turntable of the player unit 4, it is supplied to the system controller 7 as a mounting end signal. Therefore,
When the system controller 7 receives the mounting end signal (step S3), it commands the player unit 4 to rotate the disk (step S4), and commands the reading of data (step S5). The player unit 4 rotates the disc together with the turntable, and after the rotation reaches a predetermined rotation speed, reads and outputs data from the non-real time file area of the disc. The read data is supplied to the system controller 7 via the data separation circuit 6 and temporarily stored in a buffer memory (not shown) in the system controller 7. The system controller 7 sequentially writes the supplied data to the external RAM 13 (step S6), and determines whether or not the reading of the data by the player unit 4 is completed (step S7). For example, until the bit indicating the end of data supply is supplied and it is found that the reading of data is completed, step S6 is performed.
The data supplied by the execution of is written in the RAM 13. When the reading of the data is completed, an operation stop command is issued to the player unit 4 (step S8), and a disc return command is issued to the disc transport unit 3 (step S9). Therefore, the player unit 4
Stops the rotational drive of the turntable, and thereafter, the disc transport unit 3 transports and stores the disc on the turntable to the predetermined storage position of the disc in the disc storage unit 2. System controller 7 is step S9
After execution of, it is determined whether or not another new disk is stored (step S10). If another new disk is stored in the disk storage unit 2, the process proceeds to step S2, and if no other new disk is stored, the installation operation ends.

The data to be written in the RAM 13 may be all the above-mentioned data of the access information file and the karaoke information file, but at least the disc number peculiar to the disc, the address indicating the storage position of the disc storage portion 2 of the disc, the song title, and the singer. Name, lyricist name, composer name,
Song length, copyright code, song genre, song tempo,
Only the song data such as the difficulty level of the song and the multi-audio mode may be used.

The storage of a new disc can be obtained by an input from the operation unit 15 by the user. Further, a sensor for detecting the presence / absence of a disc is provided at each storage position of the disc storage unit 2, and an area for storing the detection result is provided in the RAM 13, and the detection outputs of all the sensors and the storage contents of the RAM 13 for each installation operation. And compare
The detection result may be written in the RAM 13 while determining whether a new disk is stored.

Further, in the above embodiment, the song data such as the song name is obtained at the time of installation of the disc in which the image data and the audio data are recorded. However, from a dedicated disc in which only the song data such as the song name is recorded. You may get song data when you install the disc. Alternatively, the song data of a plurality of discs on which image data and audio data are recorded is recorded on one of the plurality of discs, and these song data are obtained at the time of installation of this one disc. May be.

After the installation operation is performed as described above, karaoke reproduction of the song selected by the user becomes possible. First, in the music selection operation, the user inputs a music selection number by operating the number keys or the alphabet keys of the operation unit 15 or the remote control transmitter 23. The song selection number has a plurality of digits and is a number that designates the disc and the song recorded on the disc. When the key is operated, it is held in a buffer (not shown) in the operation unit 15. As shown in FIG. 5, the system controller 7 determines whether or not a music selection key (not shown) of the operation unit 15 is operated at a predetermined timing or by an interrupt operation (step S
11) If the music selection key is operated, the music selection number is read from the above buffer and written in the music selection list table of the RAM 13 (step S12). The music selection list table is formed in the RAM 13 and, as shown in FIG. 6, a music selection number and a recording flag which will be described later are written in the order of reproduction, and the order is advanced when the reproduction is completed. The song name corresponding to the read song selection number is read from the RAM 13 as information data (step S13), and the read data is supplied to the display character control circuit 20 (step S1).
4). The display character control circuit 20 generates display character data indicating the song title and writes it at a predetermined position in the V-RAM. The display character data is read out from the V-RAM, converted into a character image signal, and then output to the image synthesizer 21. When the character video signal is a signal indicating a predetermined color in the image synthesizer 21, the character video signal is output instead of the video image signal from the D / A converter 12 to be synthesized with the video image signal. Therefore, it is confirmed that the music title is displayed as a character image on the display 22 and the music selection by key operation is accepted.

The system controller 7 executes step S14.
After execution of, the copyright code corresponding to the read song selection number is read from the RAM 13 (step S15). RAM
Since the copyright code is included in the data written and read from the disk at the time of the installation operation, the data is read from the No. 13. The copyright code is a code indicating the copyright holder of the song. It is determined whether the selected song is a recordable song based on the read copyright code (step S16). In a ROM (Read Only Memory) 14 provided outside the system controller 7, as shown in FIG. 7, a copyright code, a copyright holder, and recordability are written in advance as a recordability data table. Regarding whether or not recording is possible, "1" can be recorded and "0" cannot be recorded.
Therefore, it is determined from the recordability data table whether or not the selected song is a recordable song. If the recording is possible, a recording enable display is made (step S17), and if the recording is impossible, a recording disable display is made (step S18). These displays may be displayed on the display 22 or may be a display (not shown) provided in the apparatus for recording permission / prohibition. When displaying on the display 22, the display character control circuit 20 generates display character data indicating that recording is possible or impossible in response to a command from the system controller 7, and V-
Written to RAM.

Since the system controller 7 is capable of recording, after executing step S17, it is determined whether or not there is a recording reservation (step S19). This is determined by whether or not the recording reservation key of the operation unit 15 or the remote control transmitter 23 is operated. If there is a recording reservation, the recording flag of the above music selection list table is set (step S20). Since "0" indicating non-recording is written in advance as the initial value of the recording flag in the song selection list table, when the recording reservation key is operated, the recording flag indicating recording is made to correspond to the song selection number. Set to 1 ".

Next, the disk reproducing operation will be described. As shown in FIG. 8, when the system controller 7 first issues a command to start the reproduction by operating the keys of the operation unit 15 (step S21), the music selection number from the first reproduction order in the music selection list table formed in the RAM 13 is displayed. The recording flag is read (step S22). The disc address and the song number corresponding to the read song selection number are read from the RAM 13 (step S23), and a disc set command is issued to the disc transport unit 3 so that the disc having the read disc address is mounted on the turntable of the player unit 4. (Step S24). When the disc transport unit 3 finishes mounting the disc on the turntable of the player unit 4, it is supplied to the system controller 7 as a mounting end signal. Therefore, when the system controller 7 receives the mounting end signal (step S25), the player unit 4
To drive the disk to rotate (step S2
6) It is determined whether or not the disc reproduction can be started (step S27). For example, when the reproduction is prohibited by the key operation of the operation unit 15, the disk reproduction is not started. If the disc reproduction can be started, the disc reproduction from the track of the read music number is instructed (step S28). Therefore, the player unit 4 starts the reproduction of the music specified by the music selection number, and the reproduced video signal and audio signal are output to the display 22 and the speaker 19.

Further, it is judged from the read recording flag whether or not the recording is reserved (step S29). When the recording flag is set to "1", a recording start command is issued to the recording device 16 (step S30).
Since the audio signal including the singing sound is supplied from the amplifier 18 to the recording device 16, the recording on the compact disc is performed according to the recording start command.

The system controller 7 is step S30.
After execution of step S22, the recorded song information corresponding to the song selection number read in step S22 is read from the RAM 13 (step S
31). The recorded song information is at least a song name, a lyricist name, and a composer name, and information such as a singer, a recording date and time, and a place may be added. After these pieces of recorded music information are read out, they are output to the printer 17 (step S32). Printer 17
Prints recorded song information on a label designed to be attached to a compact disc. As a result, if the label is affixed to the label surface of the recorded compact disc, the recorded song is recorded. It goes without saying that the recorded music information may be directly printed on the label surface of the compact disc instead of the label.

The system controller 7 is step S32.
After execution of, it is determined whether or not the reproduction of the selected song is completed (step S33). This is discriminated from the time information in the control data supplied from the data separation circuit 6 by reproducing the disc. When the reproduction of the selected song is completed, a reproduction stop command is issued to the player unit 4 (step S3).
4) A disc return command is issued to the disc transport unit 3 (step S35). Therefore, the player unit 4 stops the disc reproducing operation, and the disc transport unit 3 transports the disc on the turntable to the predetermined storage position of the disc in the disc storage unit 2 after the rotation of the turntable is stopped. Store. System controller 7
After the disc return command is issued, the song order of the song selection list table is advanced by one song (step S36), and it is determined whether or not the song selection number is recorded first in the song selection list table (step S37). If the music selection number is recorded, the process returns to step S22 and the above operation is repeated. On the other hand, if the song selection number is not recorded, the reproducing operation is ended.

FIG. 9 shows another procedure of the installation operation. In this installation operation, in addition to the copyright code on the disc, the copyright holder, recording permission / prohibition, and recording permission / prohibition information registration date information are recorded, and the recording permission / prohibition data shown in FIG. The table is formed in the RAM 13 instead of the ROM 14. That is,
As shown in FIG. 9, steps S1 to S7 are the same as the installation operation shown in FIG. 4, and the read data is written in the RAM 13 via the system controller 7. In this writing operation, the copyright holder and the recording permission / prohibition data are not written in the recording permission / prohibition data table, but are simply written as data for each disc or song. When the reading of the data is completed, it is determined whether or not the recording permission information registration date read from the disc is the latest (step S41). If it is not a recording permission information registration date newer than the latest registration date stored in the RAM 13, the operation proceeds to step S8 to stop the operation of the player unit 4. On the other hand, if the recording permission information is newer than the latest registration date, the recording permission data table is updated with the read copyright holder information and recording permission information (step S42). Update according to the information registration date (step S43). After execution of step S43, the process proceeds to step S8. Steps S8 to S10 are the same as the installation operation shown in FIG.

Note that a service person such as maintenance and inspection of the karaoke reproducing apparatus described above may change the copyright holder and the recording permission / prohibition data of the recording permission / prohibition data table by operating a special key of the operation unit 15. Further, it is obvious that the recording medium on which the reproduced sounds of a plurality of songs are at least recorded is not limited to the disc, and may be another recording medium such as a tape.
