The two are connected to each other by an address bus and a control signal bus (both not shown). keyboard 26, CRT
A monitor 27 and a barcode reader 28 are connected to the input/output interface 23. The keyboard 26 has alphabetic or katakana character keys, numeric keys, song selection keys, song name list request key, request display key, CR
Keys such as arrow keys and a cancel key (both not shown) for moving the cursor on the screen of the T monitor 27 are provided. The input/output interface 23 is equipped with a video RAM (not shown) corresponding to the number of images or characters displayed on the CRT monitor 27, and a video signal corresponding to the contents of the video RAM is supplied to the CRT monitor 27, and the microprocessor The contents of the video RAM are changed according to the display data from 21. The terminal portions 22 to 2n are also configured similarly to the terminal portion 21. In addition, terminal part 2
1 to 2n are provided one for each table in the installation room of this automatic music selection and performance device, and furthermore, they are provided in a different place other than the installation room. Furthermore, it is obvious that a display device using a liquid crystal display or the like may be used instead of the CRT monitors 18 and 27 and the CRT monitor 31 described later.

The auto change disc player 3 is connected to an input/output interface 13 and is powered by a microprocessor 11.
Operations such as disc selection, song selection, and playing are performed in accordance with instructions supplied from the input/output interface 13 from the controller. A video signal from the performance of the disc outputted from the auto-change disc player 3 is supplied to a large CRT monitor 31, and an audio signal outputted simultaneously with the video signal is supplied to a speaker device 33 via an amplifier 32.

In the automatic music selection and performance apparatus having such a configuration, each of the terminal sections 21 to 2o receives requested music, that is, designated music information, and stores it in the RAM 25 in order. on the other hand,
In the central control section 1, R at each terminal section 21 to 2n
Request music stored in the AM 25 is input in a predetermined order, a performance order is determined by a method to be described later, and the auto-change disc player 3 is controlled in accordance with the performance order to respond to the request. Further, in accordance with a request for information such as a list of song titles from each of the terminal sections 21 to 2n, the central control section 1 supplies the information to the requesting terminal section for display by a method to be described later.

Next, the operation of the terminal section 21 is controlled by the microprocessor 2.
The explanation will be given according to the operation flow of No. 1. The microprocessor 21 repeatedly executes an operation input routine and a data reading and display routine. In the operation input routine,
As shown in FIGS. 2(a) to (C), first, the keyboard 2
It is determined whether or not there is a key operation of 6 (step 51).
). If there is a key operation, it is determined whether or not it is an operation of the data display request key (step 52).

If the operation is not a data display request key, it is determined whether the operation was a character key (step 53). If it is not a character key operation, it is determined whether or not it is a selection key operation (step 54), and if it is not a selection key operation, it is further determined whether or not a request display key is operated (step 55).

For example, when a key on the keyboard 26 is operated, a predetermined code corresponding to that key is stored in an input buffer (not shown) in the input/output interface 23 in the order of the key operation, so that the code can be operated from this code. It is possible to determine which key the key is. Therefore, if the operated key is a data display request key, predetermined data classification display data is output to the input/output interface 23 in order to request data classification designation (step 57). The input/output interface 23 supplies a video signal according to predetermined data classification display data to the CRT monitor 27, and displays a "list of 10 song names" on the screen of the CRT monitor 27.
, "2. Music information currently being played" and "3. Requested performance order" to be specified. At the same time, a message indicating that one of these is to be selected by operating the arrow keys for moving the cursor and operating the selection key is also displayed at the same time. Therefore, it is determined whether or not the selection key has been operated (step 58), and if the selection key has been operated, the content corresponding to the cursor position is read (step 59).
), the song title list, information on the song being played, and the requested performance order is determined (steps 60 to 62). If the song title list is selected, the process moves to step 65. If the information on the song being played is selected, a command to request information on the song being played is generated in step 63.
), if the requested performance order is selected, a request performance order list request command is generated (step 64). Note that the requested performance order referred to here is the order of requested songs that will be played from now on, and does not include the order of requested songs that have already been played. Furthermore, the data classification is not limited to the above-mentioned list of song titles, etc., but may also include data classification such as the top ten requested songs.

If the song title list is selected, predetermined list classification display data is output to the input/output interface 23 in order to request list classification designation (step 65). The input/output interface 23 supplies a video signal according to predetermined list classification display data to the CRT monitor 27, and displays "1. by genre", [2. by artist], and r3. by alphabetical order on the screen of the CRT monitor 27. ” or “4. Cancel” is displayed. You can also select one of these by operating the arrow keys for moving the cursor.
At the same time, a display indicating that one should be selected and the selection key operated is also displayed. Therefore, it is determined whether the selection key has been operated or not (step 66), and if the selection key has been operated, the content corresponding to the cursor position is read (step 67), and the information is sorted by genre, artist, alphabetical order, and cancel. It is determined whether any of them has been selected (steps 68 to 70). If genre is selected, predetermined genre classification display data is output to the input/output interface 23 in order to request genre classification designation (step 71). The input/output interface 23 supplies a video signal according to predetermined genre classification display data to the CRT monitor 27, and displays "1. Popular songs,""2.Enka,""3. New music," or "New music" on the screen of the CRT monitor 27.
4° Lock” is displayed. At the same time, a message indicating that one of these songs should be selected by operating the arrow keys for moving the cursor and operating the song selection key is also displayed. Therefore, it is determined whether the selection key has been operated or not (step 72), and if the selection key has been operated, the content corresponding to the cursor position is read (step 73), and one of popular songs, enka, new music, and rock is read. Determine whether or not is selected (
Steps 74-77). One of popular songs, enka, new music, and rock depending on the discrimination results.
A command to request a song title list of two genres is generated (steps 78 to 81). If "by artist" is selected, a command to request a list of song names by artist is generated (step 82); if "by alphabetical order" is selected, a command to request a list of song names by 50 syllabary order is generated (step 83); otherwise In other words, in the case of cancellation, a screen erase command is generated (step 84). Each song name list request command is sent to the input/output interface 1 via the input/output interface 22.
2, and is read in an interrupt operation of the microprocessor 11 in the central control unit 1, which will be described later. The screen erase command is output to the input/output interface 23, and the entire display on the screen of the CRT monitor 27 is erased.

In addition, in the case of specifying by artist, a command to request a list of song titles of the specified artist may be generated by requesting input of a character key to specify the artist. Also, in the case of 5o alphabetical order, “Ah, I, Ka...
It is also possible to request the user to specify which one of the notes and generate a command to request a list of music titles for the specified note.

Furthermore, the genres are not limited to the above-mentioned popular songs, but also include tango, chanson, jazz, etc.

If the selection key is not operated in step 66,
It is determined whether the cancel key has been operated (step 85). If the cancel key is operated, the process moves to step 84, and if the cancel key is not operated, the process moves to step 66, where it is determined whether the selection key has been operated.

This also applies to steps 89 and 90. Note that if cancellation is specified or the cancel key is operated, the process may return to step 57.

If a character key is operated in step 53, the code in the input buffer in the input/output interface 23 is read (step 87), and display data is output to the human output interface 22 in order to display the input characters on the CRT monitor 27 (step 87). Step 88). Therefore, each time a character key on the keyboard 26 is operated, the characters corresponding to the operated character key are displayed in order from a predetermined position on the screen of the CRT monitor 27.

If it is determined in step 54 that the selection key has been operated, it is determined whether the song title list is being displayed (step 91). If the song title list is being displayed, the song title at the current cursor position on the screen of the CRT monitor 27 is assumed to be selected and the song title data is read (step 92);
Display data requesting the input of the request book title as song specification sender information is outputted to the input/output interface 22 (step 93), and it is determined whether the request book title has been input (step 94). Therefore, for example, "Request book name?" is displayed on the screen of the CRT monitor 27 in a part other than the song title list display area or in a window, and the user is requested to input the request book name. Enter the request document title and finally operate the selection key. Note that the character corresponding to the operated character key is displayed on the screen of the CRT monitor 27 as in step 88, and is erased together with the display of the above-mentioned "Request book title?" by the last operation of the selection key. If the request book title is input, the request book name is read as requester data (step 95).
), the read song title data and requester data are stored in order in the requested song area formed in the RAM 25 as shown in FIG. 10 (step 96).

If the song name list is not displayed, determine whether a character code string is held in the input buffer (step 9), and if a character code string is held by operating a character key, change that character code string to the song name. Read as data (step 100), proceed to step 93, and store it in the RAM 25.
The read song title data and requester data are stored in the requested song area formed within the music area.

If it is determined in step 55 that the request display key has been operated, the song title data DA l stored sequentially from the first song in the requested song area in the RAM 25.
+, DA 12... Step 9
7) Output display data corresponding to each of the read song title data to the input/output interface 23 (step 98). As a result, the title of the currently requested song is displayed on the screen of the CRT monitor 27 as a request.

On the other hand, if there is no key operation on the keyboard 26 in step 51, it is determined whether or not a barcode has been input (step 101). The barcode reader 28 prints each song title in a song title list book for karaoke etc.
Alternatively, the barcode displayed on the screen of the CRT monitor 27 along with the song name in the song name list is read, and the read barcode is sent to the input/output interface 23 in a barcode input buffer ( (not shown). If a barcode is input, the barcode is read from the barcode input buffer as song title data (step 102), and the process proceeds to step 93, where the read song title data is stored in the requested song area formed in the RAM 25.

Note that the cursor movement operation using the arrow keys is controlled in accordance with the operation of the arrow keys in other routines.

Next, in the data reading and display routine, as shown in FIG. 3, the microprocessor 21 first determines whether data has been supplied from the central control unit 1 (step 111). If data is supplied from the central control unit 1, it is read (step 112), and the read data is any of song title list data, currently playing song content data, requested performance order data, and memory cancel data. (Steps 113 to 11)
6). If it is song title list data, it is stored in a predetermined area of the RAM (step 117), and the song title list data is output as display data to the input/output interface 23 in order to display the song title list on the CRT monitor 27 (step 118). As a result, the requested song title list is displayed on the CRT monitor 27, and at this time, the song name list can be scrolled and displayed by operating the arrow keys. In the case of content data of the song being played, the content data of the song being played is used as display data at the input/output interface 2.
3 (step 119). As a result, the lyrics and video of the song being played are displayed on the CRT monitor 27.

In the case of requested performance order data, the requested performance order data is used as display data at the input/output interface 2.
3 (step 120). As a result, the current requested performance order is displayed on the CRT monitor 27. On the other hand, in the case of memory cancel data, since it was played in response to a request, the first song in the requested song area of the RAM 25 is erased, and all remaining requests are incremented by 1 and rewritten (step 121). That is, song title data DAl+ and requester data DBI,
, DAl2 to DAl, and DB12 to DB
The requests are moved up so that it becomes l+.

When the microprocessor 21 is supplied with a request read command, which will be described later, from the central control unit 1, it stops the processing operation of the routine currently being processed and shifts to processing of the interrupt routine. In this interrupt routine, as shown in FIG. 4, it is determined whether or not song title data is stored in the requested song area in the RAM 25 (step 131).
If no song title data is stored in the requested song area, the no-request data is output to the input/output interface 22 to be supplied to the central control unit 1 (step 132).
). If song title data is stored in the requested song area, the song title data and requester data are sequentially read from the first song in the requested song area (Step 133), and the read song title data and requester data are stored as terminal number data. At the same time, the data is sequentially outputted to the input/output interface 22 in order to be supplied to the central control unit 1 as one request data (step 134).

Then, it is determined whether or not a predetermined number A (for example, 2) of request data has been sent (step 135).
If the number has not been reached, the process returns to step 114 to read out the next song title data and requester data. When the predetermined number A is reached, the process returns to the routine that was being processed. When sending the song title data and requester data to the central control unit 1, a control signal notifies the central control unit 1 of the start and output of data sending. Note that if the number of requested songs has not reached the predetermined number A, only the number of requested songs at that time is sent out.

Although the operation of the terminal section 21 has been described, the same operation as that of the terminal section 21 is performed in the terminal sections 22 to 2n.

Next, the operation of the central control unit 1 will be explained according to the operation flow of the microprocessor 11. microprocessor 11
repeatedly executes routines such as a request reading routine, a request performance priority setting routine, a request performance order determining routine, a performance routine, and a request data sending routine.

First, in the request reading routine that is executed at predetermined intervals, as shown in FIGS. 5(a) to 5(e), a terminal number is first stored in the designated terminal area formed in the RAM 16 as shown in FIG. If the terminal number is stored, it is determined whether the variable X is equal to 0 (step 137). The variable X is initially set to 0 when the power is turned on, and is changed by being set or calculated as described below. If x-0, the frequency y of performing the specified mode of reading requests only from the specified terminal part
is read (step 138), and the variable X is made equal to the read frequency y (step 139). For example, the frequency y may be input at the same time as key operation input to memorize the terminal number in the designated terminal area.
It can be stored at a predetermined location within. Step 13
After executing step 9, it is determined whether the variable X is equal to 1 (step 140). Further, if it is determined in step 137 that X≠0, step 140 is immediately executed. x
If -1, a normal mode subroutine for reading requests from all terminal units 22 to 2o is processed (step 41), and if X≠1, a specified mode subroutine is processed (step 142).

In the case of the normal mode subroutine, the variable m is set equal to 1 (step 143), and it is determined whether the terminal unit 2m is in use (step 144). The term "in use" means, for example, that the terminal section 2m is powered on, and whether each of the terminal sections 21 to 2n is in use or not is set in the central control section 1 by, for example, a key operation by the user. If the terminal section 2m is in use, a request read command is issued to the terminal section 2m (step 145). The request read command is supplied to the input/output interface 12 and sent from the input/output interface 12 to the terminal section 2m by a control signal.
The input/output interface (in the case of the terminal section 21, the input/output interface 22) is supplied with the input/output interface. After the request read command is generated, the terminal number data,
It is determined whether or not request data consisting of song title data and requester data is supplied from the terminal section 2m (step 146). If the request data is supplied, the request data is read (step 1).
47), and writes it to the 2m request song area in the RAM 16 (step 148).

Then, it is determined whether all the predetermined number A of request data supplied from the terminal section 2m have been read (step 149), and when all the request data from the terminal section 2m has been read, 1 is added to the variable m (step 149). 150). On the other hand, if request data is not supplied from the terminal section 2m, it is determined whether or not no-request data is supplied (step 151), and if no-request data is supplied, the process proceeds to step 150.

Further, if it is determined in step 144 that the terminal section 2m is not in use, the process also proceeds to step 150. In step 150, the variable m is set to 1.

After the addition, it is determined whether the variable m is greater than the number of terminals n (step 152); if m≦n, the process moves to step 144; if man, the routine ends. By processing this request reading routine,
When a request is made in each of the terminal sections 21 to 2n, at most a predetermined number A of requested song titles and requested book titles are written as data in each of the request song areas 21 to 2n in the RAM 16. In addition, 21 in RAM16
~2n request song area is each terminal section 21~2o
The requested music area is formed in the same way as the requested music area in the RAM 25, but the terminal number is also stored therein.

In the case of a specified mode subroutine, set the variable W equal to 1 (step 153) and set the W of the specified terminal area.
Step 154) reads out the terminal number stored number m as number m, and the process proceeds to step 155. Steps 155 to 160 are similar operations to steps 144 to 149. Therefore, when all the request data supplied from the terminal unit 2m has been read in step 160, it is determined whether all the terminal numbers stored in the designated terminal area have been read out (step 161), and all the terminal numbers have been read out. If not, add 1 to the variable W (step 162).
, return to step 154. Once all terminal numbers stored in the designated terminal area have been read out, this routine ends. If request data is not supplied from the terminal unit 2m in step 157, it is determined whether or not no-request data has been supplied (step 163), and if no-request data has been supplied, the process proceeds to step 161.

In this specification mode, even if request data is stored in each terminal section 21~2°, the requested song title and request book title will not be written to the requested song area 21~2n in the RAM 16 unless it is the designated terminal section. It is.

After the subroutine processing in the normal mode or specified mode, 1 is subtracted from the variable X (step 164), and this routine ends.

For example, when the read frequency y is 1, it becomes X -1, so the normal mode is executed and requests are read from all the terminal units 21 to 2n. Also, if the reading frequency y is 2, it becomes , requests are read from all the terminal units 21 to 2n in the normal mode, and since it becomes x-0 in the next processing cycle, the frequency y is read again. Therefore, when request data is read in the specified mode, the frequency with which the requested music of the specified terminal section is played can be increased.

Note that the terminal number of the designated terminal area in RAM 16 and the frequency y of the predetermined position can be written using keyboard 1.
Perform step 7. For example, when a predetermined key operation is performed, the microprocessor 11 displays a predetermined number of "designated terminal number:?" and "frequency:?" on the CRT 1g screen.
'' is displayed and the terminal number is entered manually using the numeric keys at the ``?'' part, and the input terminal number is written in the designated terminal area in the RAM 16 by operating the setting key, and the frequency is also written in a predetermined position.

Further, the frequency y is an integer greater than or equal to 1, and is automatically set to 1 if it is not input. Furthermore, without determining whether or not the terminal section 2m is in use, if no request data is supplied to the request read command and there is no response, the terminal section 2m is determined to be not in use. Also good.

Further, instead of automatically switching between the normal mode and the specified mode as described above, the switching between the normal mode and the specified mode may be performed by a command from the keyboard 17 of the central control unit a.

Next, the request performance priority setting routine is
Interrupt processing is performed by operating the setting key 7.

In the requested performance priority setting routine, as shown in FIG. 6, first, predetermined performance priority setting display data is output to the input/output interface 14 in order to request performance priority designation (step 165). The input/output interface 14 supplies a video signal according to predetermined performance priority setting display data to the CRT monitor 18, and "Priority number 1: ?" and "Priority number 2: ?" are displayed on the screen of the CRT monitor 18. It will be displayed as... The user says “
? For example, by operating the numeric keys on the keyboard 17, the terminal number for which the request among the terminal sections 21 to 2n should be given priority and played is entered in the section ``.''. It is not necessary to prioritize all the terminal sections 21 to 21, and it is sufficient to perform this only on the terminal sections that should be prioritized. Therefore, it is determined whether or not a numeric key has been operated (step 166). If a numeric key has been operated, the numeric code corresponding to that operation is read and the numeric code is output to the input/output interface 14 as character display data. (Step 167). This allows CRT
The number corresponding to the operated number key is displayed on the screen of the monitor 18 as the terminal number to be played with priority. Then, it is determined whether or not the setting key has been operated (step 168). If the setting key has been operated, the terminal number data of each input priority level is
The data is read from the first place (step 169), and written in order from the first place to the performance priority area formed in the RAM 16 as shown in FIG. 12 (step 170).

Therefore, through the processing of this request performance priority setting routine, terminal numbers are stored in the performance priority area in the RAM 16 in the order in which the priorities are set, and terminal numbers for which priorities are not set are set randomly or in the order in which the requests are sent.

Note that this performance priority area is initially set in the order of terminal number or request transmission order unless the request performance priority setting routine is processed. Furthermore, if the cancel key is operated in steps 166 and 168, this routine may be terminated.

In the requested performance order determination routine, as shown in FIG. 7, first, the variables S and t are both set equal to 1 (step 171), and the terminal number of S in the performance priority area is read as m (step 172). ), 2
It is determined whether the requested song title data is written in the m-requested song area (step 173). That is, if the terminal number with the highest priority is n-8 as shown in FIG. 12, it becomes m-n-8. If the requested song name is written in the 2m request song area, 2
Read out the song title data and requester data for the first song in the m-request song area (step 174), and write them together with the terminal number data in the t-th song in the performance order area formed in the RAM 16 as shown in FIG. 13 (step 175). , add 1 to the variable t (step 176)
, and adds 1 to the variable S (step 177).

If the requested song title is not written in the 2m requested song area, the process immediately moves to step 177. After step 177, it is determined whether the variable S is greater than the number of terminals n (step 178), and if s≦n,
Returning to step 172, if sin, the processing of this routine ends. Through the processing of this requested performance order determination routine, a total of t requested songs are written in the performance order area in the performance order area. Note that the request performance order determining routine is processed every time the request reading routine is performed, but it may be processed subsequently after the request performance priority setting routine is interrupted. In addition, in the case of s>n, if the number of t songs written in the performance order area is less than the predetermined number, the song title data and requester data of the second song in the 2m request song area are read out and written in the performance order area. It's okay. By doing so, the performance order can be the requested order, a completely random order, or a desired priority order.

Next, in the performance routine, as shown in FIG. 8, it is first determined whether or not the performance key of the keyboard 17 has been operated (step 180). If the performance key has been operated, the variable U is set to 1. Step 181) , RAM
Step 182) to read the terminal number data, song title data and requester data of the 0th song from the performance order area No. 16 (step 182), and supply the read song title data to the auto change disc player 3 (step 183).
), and outputs performance start command data including song title data and requester data to the terminal section of the read terminal number (step 184). The performance start command data is supplied to the terminal section of the terminal number read from the input/output interface 12, and in the terminal section supplied as described above, the title of the next performance song and the title of the requested book are displayed on the CRT monitor 27, and the requester is informed. It evokes preparations to sing against the audience. After executing step 184, it is determined whether a predetermined time has elapsed (step 185), and step 184 is executed until the predetermined time has elapsed.

This predetermined time is longer than the performance start preparation time required by the auto-change disc player 3.

When a predetermined period of time has elapsed, a play start command is issued to the auto-change disc player 3 (step 186).
This routine ends.

If the performance key is not operated in step 180, it is determined whether a performance end command has been supplied from the auto-change disc player 3 (step 187). When the performance end command is supplied, the above-mentioned memory cancel data is output to the terminal section of the terminal number, and the first song in the requested song area of the terminal number in the RAM 16 is erased, and all the remaining requests in the order are only 1. The data is incremented and rewritten (step 188).

Then, 1 is added to the variable U (step 189), and it is determined whether or not the variable U is greater than the variable t1, that is, the number of songs stored in the performance order area (step 1).
90). If U≦t, proceed to step 182, and u>
If t, this routine is ended and the routine moves to a requested performance order determination routine. Note that the requested music pieces that have been played may be stored in the auxiliary storage device 20 together with the order in which they are played.

In the auto-change disc player 3, when song title data as song designation information is supplied from the central control unit 1, a disk on which the song indicated by the data is recorded is selected from a predetermined storage position and set at a predetermined performance position. , the pickup (not shown) moves from the rest position to the performance position of the designated requested song. When a play start command is supplied from the central control unit 1, the disc rotates and the pickup optically reads music information from the disc, and a playback processing circuit (not shown) outputs a video signal and two channels of audio. I get a signal.

The video signal is supplied to the CRT monitor 31 on which the lyrics and pictures of the requested song are displayed, and the audio signal is supplied to the amplifier 3.
2 to the speaker device 33, and the melody of the requested song is played. 〉+7゛When the performance of the specified requested song is finished, a performance end command is issued to the central control unit 1, the rotation of the disc is stopped, the pickup is returned to the rest position, and the disc is stored in a predetermined position. Return to position is performed.

Here, the discs used can be not only discs manufactured with image information already containing text information such as lyrics, but also discs on which image information and text information are recorded independently. If the latter disk is used, for example, only lyrics information or image information including lyrics information can be sent as a video signal to the terminal section where the requester of the song being played is located, while the other terminal sections do not contain the lyrics information. Complex processing such as sending video information that is not available as a video signal is also possible. In other words, only the lyrics information is stored in the terminal layer.
Either only image information or both lyrics information and image information can be sent from the central control unit 1 and displayed.

On the other hand, the request data sending routine is shown in FIG. 9(a).

As shown in (b), this is an interrupt routine that is processed when each request command is supplied. In this request data sending routine, when a request command is supplied, the request commands are a request performance order list request command, a currently playing song information request command, a genre-based song name list request command, an artist-specific song name list request command, and a 50-tone request command. Determine which one is the sequential song name list request command (steps 201 to 205)
. If the request command is a request performance order list request command, set the variable V equal to the variable U (step 206), and set the RA
Read the Vth song title data from the performance order area in M16 and output that song title data to the requested terminal (step 207), add 1 to variable V (step 208), and confirm that the variable ■ is greater than the value t. It is determined whether it is large (step 209). If V≦t, the process moves to step 207, and if Vat, this routine ends.

Accordingly, requested performance order data consisting of song title data including title data of the song currently being played is supplied to the requested terminal section, and the requested performance order is displayed on the CRT monitor of the terminal section.

In addition, if the request command is a command to request information on the song being played, R
Step 210) to read the U-th song title data from the performance order area in AM16, and sends a command to read song content data such as lyrics corresponding to this song title data to the auxiliary storage device 2.
0 (step 211). If the request command is a song title list request command, a command to read the list of song names by genre of popular songs, enka, new music, and rock, a command to read the list of song names by artist, and 5
A command to read out the song title list in order of zero syllables is issued to the auxiliary storage device 20 (steps 212 to 214). The auxiliary storage device 20 reads and outputs the corresponding song content data or song title list data from the recording medium in response to these read commands. Therefore, the microprocessor 11 determines whether the auxiliary storage device 20 has read out and outputted the song content data or the song title list data (step 215), and if the data has been read out and outputted, requests the data. Relay output to the terminal section (step 21
6). When sending out the song content data and song title list data to the terminal sections 21-2n, a control signal notifies the terminal sections 21-2n of the start and output of data sending.

The image auxiliary storage device 20a is compatible with playback-only or recordable and erasable recording media, and the microprocessor 11

A wireless transmitter/receiver may be provided to each other to perform wireless communication.

In addition, the central control unit 1 calculates the request frequency for each requested song, calculates the charge for the number of request responses for each terminal, and prints out the calculation results to the printer 19, or 20 may be stored.

Further, the requester data does not have to be the request originator's name itself, but may be at least the terminal number or higher, for example, the letter A of the alphabet.

Further, the requester data may not be requested manually unless it is particularly necessary.

Furthermore, although an auto-change disc player is used in the above embodiment, a tape player such as a VTR may also be used. It is also possible to connect a plurality of auto-change disc players to the input/output interface 13 and operate them individually.

Furthermore, in the above-described embodiment, a case was explained in which the operation as an automatic music selection performance device was shared between the central control section 1 and the terminal sections 21 to 2n, but each terminal section, for example,
