The keyboard 26 includes an alphabetic or katakana character key, a numeric key, a song selection key, a song name list request key, a request display key, an arrow key for moving the cursor on the screen of the CRT monitor 27, a cancel key (both not shown), and the like. The key is provided. The input / output interface 23 is provided with a video RAM (not shown) for 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 contents of the video RAM are changed according to the display data from 21. Terminal unit 2 ₂ to 2 _n may have the same structure as the terminal unit 2 _1. Incidentally, the terminal unit 2 ₁ to 2 _n further one for each table in the installation chamber of the automatic music selection playing apparatus may be provided in a different location other than the installation room. In addition, the CRT monitors 18, 27 and the CRT described later
It is obvious that a display device using a liquid crystal display or the like may be used instead of the monitor 31.

The auto-change disc player 3 is connected to the input / output interface 13 and performs operations such as disc selection, song selection, and performance according to each command supplied from the microprocessor 11 via the input / output interface 13. A video signal output from the auto-change disk player 3 based on the performance of the disk is supplied to a large-sized CRT monitor 31, and an audio signal output simultaneously with the video signal is supplied to a speaker device 33 via an amplifier 32.

In the automatic music selection playing apparatus having such a configuration is stored in each terminal unit 2 ₁ to 2 RAM 25 in _{the n} request song i.e. it accepts designation song information in order. On the other hand, the automatic change disc player 3 according to the playing order determined playing order by a method to be described later by entering the requested song stored in RAM25 in the central control unit 1, each terminal unit 2 ₁ to 2 _n in a predetermined order Control and respond to requests. Furthermore, each terminal 2 ₁ by the method described below
2 Central control unit 1 according to the information request such as the song title list from _n
Supplies the information to the requesting terminal unit for display.

Next, the microprocessor 21 operation of the terminal portion 2 ₁
The operation will be described according to the operation flow. Microprocessor 21
Repeatedly executes the operation input routine and the data reading and displaying routine. In the operation input routine, the second
First, as shown in FIGS. 7A to 7C, it is determined whether or not a key operation on the keyboard 26 has been performed (step 51). If there is a key operation, it is determined whether or not the operation is a data display request key operation (step 52). If the operation is not a data display request key operation, it is determined whether or not the operation is a character key operation (step 53). If the operation is not a character key operation, it is determined whether or not the operation is a selection key operation (step 54). If the operation is not a selection key operation, it is further determined whether or not a request display key operation is performed (step 55).

For example, when a key is operated on the keyboard 26, a predetermined code corresponding to the key is stored in an input buffer (not shown) in the input / output interface 23 in the order of the key operation. 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 to make a data classification designation request (step 5).
7). The input / output interface 23 supplies a video signal according to the predetermined data classification display data to the CRT monitor 27,
On the monitor 27 screen, it is displayed which of "1. music name list", "2. music information during performance" and "3. request performance order" is designated. Further, a display indicating that any one of these is selected by the device of the arrow key for moving the cursor and the selection key is operated is simultaneously displayed. Therefore, it is determined whether or not the selection key has been operated (step 58). If the selection key has been operated, the contents corresponding to the cursor position are read (step 59), the music title list, the music information being played, and the requested performance. It is determined whether any of the orders has been selected (steps 60 to 62). If the song name list has been selected, the process proceeds to step 65. When the music information being played is selected, a music information requesting command for playing is generated (step 63), and when the request playing order is selected, a request playing order list request command is issued (step 64). ). Note that the request performance order here is the order of the requested songs to be played, and does not include the order of the requested songs that have already been played. Further, the data classification is not limited to the above-mentioned music title list and the like, and data classifications such as the top ten of the requested music can also be considered.

When the song name list is selected, predetermined list classification display data is output to the input / output interface 23 in order to make a list classification designation request (step 65). The input / output interface 23 supplies a video signal according to the predetermined list classification display data to the CRT monitor 27, and displays “1. genre”, “2. artist”, “3.50 sound order” on the CRT monitor 27 screen. Or "4. Cancel" is displayed. In addition, a message indicating that one of these is selected by operating the arrow keys for moving the cursor and the selection key is operated is simultaneously displayed. Therefore, it is determined whether or not the selection key has been operated (step 66). If the selection key has been operated, the content corresponding to the cursor position is read (step 67).
It is determined whether any one of the sound order and the cancel is selected (steps 68 to 70). When the genre classification is selected, predetermined genre classification display data is input / output interface 23 to make a genre classification designation request.
(Step 71). I / O interface 23
Is a video signal according to the specified genre classification display data.
It is supplied to the T monitor 27 and displayed on the CRT monitor 27 screen as "1.Kyokyoku", "2.Enka", "3.New music" or "4.
"Lock" is displayed. In addition, a display indicating that any one of them is selected by operating the arrow keys for moving the cursor and the music selection key is operated is simultaneously displayed. Therefore, it is determined whether or not the selection key has been operated (step 72). If the selection key has been operated, the content corresponding to the cursor position is read (step 7).
3) It is determined whether any one of the popular song, enka, new music and rock has been selected (steps 74 to 77). Kayo, enka,
Generates a music name list request command for one of the genres of new music and rock (steps 78 to 8)
1). If artist-specific is selected, an artist-specific music name list request command is generated (step 82). If alphabetical order is selected, a musical-name-list request request is generated (step 83). Otherwise, that is, in the case of cancellation, a screen erase command is issued (step 84).
Each song name list request command is output to the input / output interface 12 via the input / output interface 22, and is read in the interrupt operation of the microprocessor 11 in the central control unit 1 described later. The screen deletion command is output to the input / output interface 23, and all the display on the screen of the CRT monitor 27 is deleted.

In the case of each artist, an operation input of a character key for designating an artist may be requested, and a command for requesting a song name list of the designated artist may be generated. In the case of the order of the Japanese syllabary, it may be possible to request which one of "Oh, Uh, ..." to be specified, and to issue a music title list request command of the specified sound.

The genre is not limited to the above-mentioned pop songs and the like, but may include tango, chanson, jazz and the like.

If the select key is not operated in step 66,
It is determined whether or not the cancel key has been operated (step 85). If the cancel key is operated, step
The flow shifts to 84, and if the cancel key is not operated, the flow shifts to step 66 to determine the operation of the select key. This is the same in steps 89 and 90. If cancel is specified or the cancel key is operated, the process may return to step 57.

If the character key is operated in step 53, the code of the input buffer in the input / output interface 23 is read (step 87), and the display data is output to the input / output interface 22 to display the input character on the CRT monitor 27 (step 87). Step 88). Therefore, each time a character key on the keyboard 26 is operated, a character corresponding to the operated character key is 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 or not a song title list is being displayed (step 54).
91). When the song title list is displayed, the current CRT monitor 27
Assuming that the song title at the cursor position on the screen has been selected, the song title data is read (step 92), and display data requesting the input of the requester name as song designation sender information is output to the input / output interface 22 (step 92).
93) It is determined whether or not the requester's name has been input (step 94). Therefore, for example, “requester name?” Is displayed on the screen other than the song title list display portion on the screen of the CRT monitor 27 or in a window, and the user is required to input the requester name. Enter the requester name with the key and operate the selection key at the end. The character corresponding to the operated character key is displayed on the screen of the CRT monitor 27 in the same manner as in step 88, and the last operation of the select key causes the "requester name?"
Will be deleted along with the display. If the requester's name is entered, the requester's name is read as requester data (step 95), and RAM2 is read as shown in FIG.
The read song name data and requester data are sequentially stored in the requested song area formed in step 5 (step 96). If the song name list is not being displayed, it is determined whether or not a character code string is held in the input buffer (step 99). If the character code string is held by operating the character keys, the character code string is read. Read as data (step 100), proceed to step 93, R
The read song name data and the requester data are stored in the request song area formed in the AM 25.

Song data DA1 ₁ when it is determined that the request display key is operated stored sequentially from the first track in the request song area in RAM25 in step 55, DA1 ₂ ...
Is read out (step 97), and the display data corresponding to each read-out song name data is input / output interface.
Output to 23 (step 98). This allows the CRT monitor 27
The title of the song currently being requested is displayed on the screen in the order of the requests.

On the other hand, if there is no key operation on the keyboard 26 in step 51, it is determined whether or not a bar code has been input (step 101). The barcode reader 28 is printed on a song title list book such as karaoke for each song title, or
The barcode displayed along with the song title in the song title list is read on the screen of the CRT monitor 27, and the read barcode is a barcode input buffer (see FIG. (Not shown). If there is a barcode input, the barcode is read from the barcode input buffer as song name data (step 102), and the flow advances to step 93 to go to the RAM.
The read song name data is stored in the request song area formed in the file 25.

Note that the cursor movement operation using the arrow keys is controlled in another routine according to the operation of the arrow keys.

Next, in the data reading and displaying routine, as shown in FIG. 3, the microprocessor 21 first determines whether or not data has been supplied from the central control unit 1 (step S1).
111). If the data is supplied from the central control unit 1, it is read (step 112), and the read data is any of the music name list data, the music content data being played, the requested performance order data, and the memory cancel data. It is determined whether or not this is the case (steps 113 to 116). If it is the song title list data, it is stored in a predetermined area of the RAM (step 117), and the song title list data is output to the input / output interface 23 as display data 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,
At this time, the song name list can be scrolled and displayed by operating the arrow keys. In the case of the music content data being played, the music content data being played is output to the input / output interface 23 as display data (step 11).
9). This causes the CRT monitor 27 to display the lyrics and images of the song being played. In the case of request performance order data, the request performance order data is output to the input / output interface 23 as display data (step 120). As a result, the current request performance order is displayed on the CRT monitor 27. On the other hand, in the case of the memory cancel data, since the performance has been performed in response to the request, the first music in the requested music area of the RAM 25 is erased, and the remaining request order is moved up by one and rewritten (step 121). That is, to erase the Song data DA1 ₁ and request user data DB1 _1, DA1 ₂ in the DA1 _1, also than advancing the request order to the DB1 ₂ to DB1 _1.

When a request read command described later is supplied from the central control unit 1, the microprocessor 21 stops the processing operation of the routine currently being processed and shifts to the processing of the interrupt routine. In this interrupt routine, it is determined whether or not song name data is stored in the request music area in the RAM 25 as shown in FIG. 4 (step 131). Outputs unrequested data to the input / output interface 22 to supply it to the central control unit 1 (step 132). If song name data is stored in the requested song area, song name data and requester data are read out in order from the first song in the request song area (step 133), and the read song title data and requester data are converted to terminal number data. At the same time, the data is sequentially output to the input / output interface 22 to be supplied to the central control unit 1 as one request data (step 134). And a predetermined number A (for example,
It is determined whether or not the request data has been transmitted only in 2) (step 135). If the request data does not reach the predetermined number A, 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 routine returns to the routine being processed. When transmitting the song name data and the requester data to the central control unit 1, the control unit notifies the central control unit 1 of the start and output of the data transmission by a control signal. If the number of requested songs does not reach the predetermined number A, the number of requested songs at that time is transmitted.

Although described operation of the terminal unit 2 _1, the same operation as the terminal unit 2 ₁ is also in the terminal unit 2 ₂ to 2 _n is performed.

Next, the operation of the central control unit 1 will be described according to the operation flow of the microprocessor 11. The microprocessor 11 repeatedly executes routines such as a request reading routine, a request performance priority setting routine, a request performance order determination routine, a performance routine, and a request data sending routine. First, in the request reading routine executed every predetermined period, as shown in FIGS. 5 (a) to 5 (c), the terminal number is first set in the designated terminal area formed in the RAM 16 as shown in FIG. Is determined (step 136). If the terminal number is stored, it is determined whether the variable x is equal to 0 (step 137). The variable x is initialized to 0 when the power is turned on, and is also set or calculated as will be described later and changes. If x = 0, the frequency y for performing the designated mode for reading the request only from the designated terminal unit is read (step 138), and the variable x is made equal to the read frequency y (step 139). For example, the frequency y can be input simultaneously with the key operation input for storing the terminal number in the designated terminal area, and can be stored in a predetermined position in the RAM 16. After executing step 139, it is determined whether the variation x is equal to 1 (step
140). If it is determined in step 137 that x ≠ 0, step 140 is immediately executed. If x = 1, to process the normal mode subroutine to read requests from all of the terminal unit 2 ₂ to 2 _n (step 141), x
If $ 1, the designated mode subroutine is processed (step 142).

In the case of the normal mode subroutine, the variable m is made equal to 1 (step 143), and it is determined whether or not the terminal unit 2m is in use (step 144). For example, “in use” means that the terminal unit 2m is in a power-on state, and whether each terminal unit 2 ₁ to 2 _n is in use or not in use is set in the central control unit 1 by, for example, a user operating a key or the like. You. If the terminal unit 2m is in use, a request read command is issued to the terminal unit 2m (step 145). Request read instruction if the output interface 12 by a control signal supplied to the input-output interface 12 input-output interface of the terminal portion 2m (Terminal unit 2 _1, input-output interface 2
2) supplied to. After the request read command is issued,
It is determined whether or not request data including terminal number data, song title data and requester data is supplied from the terminal section 2m (step 146), and if request data is supplied, the request data is read (step 147). , Write to the 2m request song area in RAM 16 (step 148). And terminal part 2m
It is determined whether all the predetermined number A of request data supplied from the terminal unit 2 have been read (step 149).
When all the request data from m have been read, 1 is added to the variable m (step 150). On the other hand, if the request data is not supplied from the terminal unit 2m, it is determined whether or not the unrequested data is supplied (step 151). If the unrequested data is supplied, the process proceeds to step 150. Also, if it is determined in step 144 that the terminal portion 2m is not in use, the process proceeds to step 150. After adding 1 to the variable m in step 150, it is determined whether or not the variable m is larger than the number of terminals n (step 152). If m ≦ n, the process proceeds to step 144,
If m> n, this routine ends. By the process of reading requests routine, each terminal unit 2 ₁ to 2 _n
Request Song and requester name of the predetermined number A is written as a data in both of each lot to 2 ₁ to 2 _n request song area of the Save path in RAM16 request. In addition, RA
2 ₁ to 2 _n request song area each terminal unit in the M16 2 ₁
It is formed similarly to the request song area in RAM25 of to 2 _n, is adapted to be also stored terminal number.

In the case of the designated mode subroutine, the variable w is made equal to 1 (step 153), and w of the designated terminal area is set.
The terminal number which is stored second is read out as the number m (step 154), and the process proceeds to step 155. Step 155
To 160 are the same as steps 144 to 149. Therefore, when all the request data supplied from the terminal unit 2m is read in step 160, it is determined whether or not all the terminal numbers stored in the designated terminal area are read (step) 161,
If not all terminal numbers have been read, the variable w
Is incremented by 1 (step 162) and the process returns to step 154. When all the terminal numbers stored in the designated terminal area have been read, this routine ends. If the request data is not supplied from the terminal unit 2m in step 157, it is determined whether or not the unrequested data is supplied (step 163). If the unrequested data is supplied, the process proceeds to step 161.

In this designated mode, _if the requested data is stored in each of the terminal units 2 ₁ to 2 _n but it is not the designated terminal unit, the requested song name and requester name are written in the 2 ₁ to 2 _n requested song area in RAM 16. There is no.

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

For example, if the frequency read y is 1, since the x = 1, read requests from all of the terminal portion 2 ₁ to 2 _n in the normal mode is executed. When the read frequency y is 2, x = 2. Therefore, in the first processing cycle, the request is read from the terminal portion of the specified terminal number in the specified mode, and x = 1 in the next processing cycle. read requests from all the terminal sections 2 ₁ to 2 _n in the normal mode, since the further the x = 0, at the next processing cycle, reload the frequency y. Therefore, when the request data is read in the designated mode, the frequency of playing the requested music in the designated terminal unit can be increased.

The writing of the terminal number of the designated terminal area in the RAM 16 and the frequency y of the predetermined position are performed by operating the keyboard 17. 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 18 screen, A number is input, and the terminal number input by operating the setting key is written in a designated terminal area in the RAM 16, and the frequency is written in a predetermined position. The frequency y is 1
This is an integer above, and is automatically set to 1 when not input. Further, without judging whether the terminal unit 2m is in use or not, if the request data is not supplied to the request read command and there is no response, the terminal unit 2m is set to be not in use. Is also good.

The normal mode and the designated mode may not be automatically switched as described above, but the normal mode and the designated mode may be switched by a command from the keyboard 17 of the central control unit 1.

Next, the request performance priority setting routine
Interrupt processing is performed by operating the 17 setting keys.
In the request performance priority setting routine, first, as shown in FIG. 6, predetermined performance priority setting display data is output to the input / output interface 14 in order to make a request for requesting performance priority (step 165). The input / output interface 14 supplies a video signal corresponding to the predetermined performance priority setting display data to the CRT monitor 18, and the screen of the CRT monitor 18 displays “priority number 1:?” And “priority number 2:?” It is displayed as ...... The user inputs a part, for example, the terminal number to be played in favor of the request of the terminal part 2 ₁ ~2 _n by the operation of the numeric keys of the keyboard 17 of the "?". This does not need to prioritize for all of the terminal portion 2 ₁ to 2 _n, it may be performed only for the terminal unit to be prioritized. Therefore, it is determined whether or not the numeric key is operated (step 166), and if the numeric key is operated, the numeric code corresponding to the operation is read and the numeric code is output to the input / output interface 14 as the character display data. I do. (Step 167). As a result, the number corresponding to the operated number key is displayed as the terminal number to be played preferentially in the "?" Part on the screen of the CRT monitor 18. Then, it is determined whether or not the setting key has been operated (step 168), and if the setting key has been operated, the input terminal number data of each priority order is read from the first (step 169) and shown in FIG. As shown, data is written in the performance priority area formed in the RAM 16 in order from the first (step 170).

Therefore, by the processing of the request performance priority setting routine, the terminal numbers are stored in the performance priority area in the RAM 16 in the order in which the priorities are set, and the terminal numbers for which no priority is set are set in random or request transmission order. If the request performance priority setting routine is not processed, the performance priority area is initially set in terminal number order or request transmission order. When the cancel key is operated in steps 166 and 168, the present routine may be terminated.

In the request performance order determination routine, first, as shown in FIG. 7, both the variable s and the variable t are made equal to 1 (step 171), and the s-th terminal number in the performance priority area is read as m (step 172). ), It is determined whether the requested song title data is written in the 2m requested song area (step 173). That is, as shown in FIG. 12, the terminal number of the first priority is n-
If it is 8, then m = n−8. If the requested song name is written in the 2m request song area, the song title data and requester data of the first song in the 2m request song area are read out (step 174), and the RAM is read as shown in FIG.
The terminal number data is written together with the terminal number data in the t-th music piece in the performance order area formed in step 16 (step 175), 1 is added to the variable t (step 176), and 1 is added to the variable s (step 177). If the requested song name is not written in the 2m requested song area, the process immediately proceeds to step 177. After step 177, it is determined whether or not the variable s is larger than the number of terminals n (step 178).
If ≦ n, the process returns to step 172, and if s> n, the processing of this routine is terminated. By the processing of the request performance order determination routine, a total of t requested music pieces are written in the performance order area in the performance order. Note that the request performance order determination routine is processed every time the request reading routine is performed, but may be performed after the request performance priority setting routine is interrupted. Further, when s> n, when the number of t songs written in the performance order area is less than the predetermined number of songs, the song name data and requester data of the second song of the 2m request music area are read and written in the performance order area. May be. By doing so, the order of performance can be in the order of request, or completely random,
Alternatively, the order can be set to an order such as a desired priority.

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 one. Equalize (step 181), and read out the terminal number data, music name data and requester data of the u-th music from the performance order area of the RAM 16 (step 18).
2) The read song name data is supplied to the auto change disc player 3 (step 183), and the performance start command data including the song title data and the requester data is output to the terminal portion of the read terminal number. (Step 184). The performance start command data is supplied to the terminal section of the terminal number read out from the input / output interface 12. In the terminal section supplied as described above, the next music piece name and requester name are displayed on the CRT monitor 27, and the requester To prepare to sing. After execution of 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 in the auto change disc player 3. When the predetermined time has elapsed, a performance start command is issued to the automatic change disc player 3 (step 186), and this routine ends.

If the performance key is not operated in step 180, it is determined whether or not a performance end command is 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 portion of the terminal number, the first song of the request song area of the terminal number in the RAM 16 is erased, and the remaining request order is all 1's. Move forward and rewrite. (Step 188). Then, 1 is added to the variable u (step 189), and the variable u
Is larger than the above-mentioned variable t, that is, the number of pieces of music stored in the performance order area (step 190).
If u ≦ t, the process proceeds to step 182, and if u> t,
This routine is terminated and the request performance order determination routine is entered. The requested music piece played may be stored in the auxiliary storage device 20 together with the playing order.

In the auto-change disc player 3, when the song name data as song designation information is supplied from the central control unit 1, the disc on which the song indicated by the data is recorded is selected from a predetermined storage position and set to a predetermined performance position. Then, a pickup (not shown) moves from the rest position to the performance position of the designated request music. When a performance start command is supplied from the central control unit 1, the disc is rotated and the pickup optically reads out music information from the disc, for example, and a video signal and 2 are read by a reproduction processing circuit (not shown).
The audio signal of the channel is obtained. Video signal is CR
The tune and the picture of the requested music are supplied to the T monitor 31, and the audio signal is supplied to the speaker device 33 via the amplifier 32, and the melody of the requested music flows.
Next, when the performance of the designated request music is completed, a performance end command is issued to the central control unit 1 to stop the rotation of the disk, return the pickup to the rest position, and return the disk to the predetermined storage position. Is performed.

Here, the disc to be used is not only a disc manufactured with image information already containing character information such as lyrics,
A disk in which image information and character information are recorded independently can also be used. Using the latter disc, for example,
Only the lyrics information or image information containing the lyrics information is sent as a video signal to the terminal where the requester of the music being played is located, and video information not containing the lyrics information is sent as a video signal to the other terminals. Such complicated processing is also possible. That is, only the lyrics information, only the image information, or both the lyrics information and the image information can be arbitrarily sent from the central control unit 1 and displayed for each terminal unit.

On the other hand, the request data sending routine is shown in FIG.
This is an interrupt routine that is processed when each request command is supplied as shown in FIG. In this request data transmission routine, when a request command is supplied, the request command is a request for a request for a performance order list, a request for information on the tune being played, a request for a list of tune names by genre, a request command for a list of tune names by artist, and a 50-sound. It is determined which of the order-specific music name list request commands is present (steps 201 to 205). The variable v if the request command is a request playing order list request command
Equal to the variable u (step 206), read the song name data of the v-th song from the performance order area in the RAM 16, output the song name data to the requested terminal section (step 207), and add 1 to the variable v. (Step 208), and it is determined whether or not the variable v is larger than the numerical value t (step 208).
209). If v ≦ t, the process proceeds to step 207, and if v> t, this routine ends. Accordingly, request performance order data including music name data including the music name data currently being played is supplied to the requested terminal unit, and the requested performance order is displayed on the CRT monitor of the terminal unit.

Also, if the request command is a command for requesting information on the song being played,
The song name data of the u-th song is read from the performance order area in the RAM 16 (step 210), and a song content data read command such as lyrics corresponding to the song name data is issued to the auxiliary storage device 20 (step 211). When the request command is a song name list request command, a song name list read command for each genre of song, enka, new music and rock,
A command to read the music name list for each artist and a command to read the music name list for each syllabary are issued to the auxiliary storage device 20 (steps 212 to 214). The auxiliary storage device 20 reads out the corresponding music content data or music title list data from the recording medium in response to these read commands, and outputs the read music content data. Therefore,
The microprocessor 11 determines whether or not the auxiliary storage device 20 has read and output the music content data or the music title list data (step 215), and if the data has been read and output, the terminal requesting the data. It is relayed to the department (step 216). The music content data and Song list data informing transmission start and output of data by the control signal in the case of sending to the terminal unit 2 ₁ to 2 _n to the terminal unit 2 ₁ to 2 _n.

Image auxiliary storage device 20a corresponds to a read-only or recording and erasable recording medium, 2 from time to time each terminal unit based on the command of the microprocessor 11 ₁ to 2 _n of the CRT monitor 27
Alternatively, the image information is sent to the CRT monitor 31. This allows
All responses were end to a request from the terminal unit 2 ₁ to 2 _n, and when in the request wait state, information including a commercial message when some free time disk replacement or the like of the automatic change disc player 3 has occurred (e.g. , A request is being received) or a simple background image can be displayed on the CRT monitor 27 or 31.

In the embodiment described above, but between the central control unit 1 and the terminal unit 2 ₁ to 2 _n are connected by a cable such as a wired communication is performed, the central control unit 1 and the terminal portion
2 ₁ may be carried out wireless communication by providing each other wireless transceiver between to 2 _n.

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

Also, the requester data need not be the request sender name itself, but may be at least the content of the terminal number or more, for example, about A in the alphabet. If the requester data is not particularly required, an input request may not be made.

Further, in the above-described embodiment, the auto change disc player is used, but a tape player such as a VTR may 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.
