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, in the central control unit 1, the request music pieces stored in the RAM 25 in each of the terminal units 2 ₁ to 2 _n are input in a predetermined order, the playing order is determined by a method described later, and the automatic change disc player 3 is set in accordance with the playing order. Control and respond to requests. In addition, each terminal section 2 ₁ to 2 _n
In response to a request for information such as a music title list from the central control unit 1, the central control unit 1 supplies the information to the requesting terminal unit and displays it.

Next, the operation of the terminal portion 2 ₁ according to the operation flow of the microprocessor 21. The microprocessor 21 repeatedly executes the operation input routine and the data read / display routine. In the operation input routine, as shown in FIGS. 2A to 2C, first, it is determined whether or not the key operation of the keyboard 26 has been performed (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 it is not the operation of the data display request key, it is determined whether or not it is the operation of the character key (step 53). If it is not a character key operation, it is determined whether it is a selection key operation (step
If the selection key is not operated, it is further determined whether or not the request display key is operated (step 55).

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

When the music title list is selected, predetermined list classification display data is output to the input / output interface 23 to request a list classification designation (step 65). The input / output interface 23 supplies a video signal corresponding to predetermined list classification display data to the CRT monitor 27, and "1. By genre", "2. By artist", "3.50 By sound order" is displayed on the screen of the CRT monitor 27. Alternatively, it is displayed whether to specify “4. Cancel”. In addition, a display indicating that any one is selected from these by operating the arrow keys for moving the cursor and the selection key is operated is also displayed. Therefore, it is determined whether or not the selection key is operated (step 66), and if the selection key is operated, the content corresponding to the cursor position is read (step 67), genre, artist, 50
It is determined whether any one of the note order and the cancel is selected (steps 68 to 70). When the genre classification is selected, predetermined genre classification display data is output to the input / output interface 23 to make a genre classification designation request (step 71). The input / output interface 23 CRTs the video signal according to the predetermined genre classification display data.
It is supplied to the monitor 27, and "1. Kayokyoku", "2. Enka", "3. New Music" or "4.
Whether to specify "Lock" is displayed. In addition, a display indicating that any one of these keys is operated by operating the arrow key for moving the cursor and the music selection key is operated is also displayed. Therefore, it is determined whether or not the select key is operated (step 72), and if the select key is operated, the contents corresponding to the cursor position are read (step 7).
3), it is determined whether any of the popular songs, enka, new music and rock is selected (step
74-77). A masterpiece list request command for one of genres of popular songs, enka, new music, and rock is generated according to the discrimination result (steps 78 to 81).
When the artist type is selected, a song name list request command by artist is generated (step 82), and when the 50-sound order is selected, a song name list request command by 50-sound order is generated (step 83), Otherwise, that is, in the case of cancellation, a screen erase command is generated (step 84). Each music title list request command is output to the input / output interface 12 via the input / output interface 22 and 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, the operation input of the character key for designating the artist may be requested and the song name list request command of the designated artist may be generated. Further, in the case of the Japanese syllabary order, it may be possible to request which one of "A, I, U ..." Is designated and generate a music title list request command of the designated tone.

The genres are not limited to the above-mentioned songs and the like, but may be 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 is operated (step
85). If the cancel key is operated, step 84
If the cancel key is not operated, the process proceeds to step 66 and the operation of the selection key is determined. This also applies to steps 89 and 90. If cancel is designated or the cancel key is operated, the process may return to step 57.

When 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 88). Therefore, every time the character key of the keyboard 26 is operated, the 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 the song name list is being displayed (step 9
1). If the song name list is being displayed, it is assumed that the song name at the cursor position on the screen of the current CRT monitor 27 has been selected and the song name data is read (step 92), requesting the input of the requester name as the song designated caller information. Output the display data to the input / output interface 22 (step 9
3), it is determined whether or not the requester name is input (step 94). Therefore, for example, on the screen of the CRT monitor 27, "requester name?" Is displayed in a part other than the song name list display part or a window, and the user is requested to input the requester name. Enter the requester's name with the key and operate the select key at the end. The character corresponding to the operated character key is displayed on the screen of the CRT monitor 27 as in step 88, and the "requester name?"
Will be erased with the display of. If the requester name is input, the requester name is read as requester data (step 95), and RAM2 is displayed as shown in FIG.
The read song title data and requester data are stored in order in the request song area formed in 5 (step 96). If the song name list is not being displayed, it is judged whether or not the character code string is held in the input buffer (step 99). If the character code string is held by the character key operation, that character code string is used as the song name data. Read as (step 100), go to step 93 RAM
The read song title data and requester data are stored in the request song area formed in 25. Further, as shown in FIG. 9, the request music area is also provided with an area for storing the read title data indicating that the written music title data and requester data have been read by the central control unit 1.

When it is determined in step 55 that the request display key has been operated, all the song title data DA ₁ , DA ₂ ... Stored in order from the first song in the request song area in the RAM 25 are read (step 97), and each of the read items is read. Input / output interface for display data corresponding to song title data 23
(Step 98). As a result, the song names currently requested are displayed on the screen of the CRT monitor 27 in the order of requests.

On the other hand, if there is no key operation of the keyboard 26 in step 51, it is determined whether or not there is a bar code input (step 101). The bar code reader 28 is printed for each song name in a song name list book such as karaoke, or CR
The bar code displayed on the screen of the T-monitor 27 together with the track names in the track name list is read, and the read bar code is a bar code input buffer (Fig. (Not shown). If there is a bar code input, the bar code is read from the bar code input buffer as song title data (step 102) and the process proceeds to step 93 and RAM 25
The read song title data is stored in the request song area formed therein.

The cursor movement operation by the arrow keys is controlled according to the operation of the arrow keys in another routine.

Next, in the data read and display routine, as shown in FIG. 3, the microprocessor 21 first determines whether or not the data is supplied from the central control unit 1 (step
111). When the data is supplied from the central control unit 1, it is read (step 112), and the read data is any of the music title list data, the music content data being played, the requested performance order data, and the memory cancellation data. It is determined whether or not (steps 113 to 116). If the music title list data is stored in a predetermined area of the RAM (step 117), the music title list data is output to the input / output interface 23 as display data for displaying the music title list on the CRT monitor 27 (step 118). As a result, the requested song list is displayed on the CRT monitor 27,
At this time, the music title 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). As a result, the CRT monitor 27 displays 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 CRT monitor 27 displays the current request performance order. On the other hand, in the case of the memory cancel data, the first song in the requested song area of the RAM 25 is erased because it was played in response to the request, and the remaining request order is moved up by 1 and rewritten (step 121). That is, the song title data DA ₁ , the requester data DB ₁ and the read completion data DC ₁ are erased, DA ₂ is set as DA ₁ , DB ₂ is set as DB ₂ .
_The request order is increased to ₁ and DC ₂ to DC ₁ .

When a request read command, which will be 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, the variable g is set to 1 as shown in FIG. 4 (step 131), and it is determined whether or not the song title data is stored in the gth request song area in the RAM 25 (step 132). If no song title data is stored in the requested song area, the unrequested data is output to the input / output interface 22 so as to be supplied to the central control unit 1 (step 133). If the song title data is stored in the gth requested song area, it is determined whether the song title data has already been read (step 134). If already read, step 1 below
38: Requested song area read completion data DC
Since g is set to 1, if DCg = 0, it is determined that the initial setting remains and the data has not been read yet.
If DCg = 1, it has been read, so 1 is added to the variable g (step 135), and the routine proceeds to step 132. If DCg = 0, song name data and requester data are read in order from the g-th request song area (step 13).
6) The read music title data and requester data are sequentially output to the input / output interface 22 so as to be supplied to the central control unit 1 as one request data together with the terminal number data (step 137). Then, the read completion data DCg of the requested music area is set to 1 (step 138).

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 at every predetermined cycle, as shown in FIG.
The variable m is made equal to 1 (step 143) and the terminal part 2
It is determined whether _m is in use (step 144). For example, “in use” means that the terminal unit 2 _m 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. To be done. If the terminal 2 _m is in use,
A request read command is issued to the terminal unit 2 _m (step 145). Request read command (in the case of the terminal unit 2 _1, input-output interface 22) from the output interface 12 by a control signal supplied to the output interface 12 the terminal section 2 _m output interface supplied to. After the request read command is issued, the request data consisting of terminal number data, song name data, and requester data is displayed in the terminal section.
It is determined whether or not the data is supplied from 2 _m (step 146), and if the request data is supplied, the request data is read (step 147) and the terminal number data is stored in the request data area (Fig. 10) in RAM16. At, song title data Bt and requester data Ct are written (step 148). Here, t is a variable indicating the reading order, and is initialized to 1 when the power is turned on. Then, it is determined whether or not the request data has been read from the terminal section 2 _{m in} the period up to the tkth before this time (step 149). k is a predetermined value, for example, 10. t-
If the request data is read from the terminal unit 2 _{m in} the period up to the kth, the read frequency data Dt is set to 0 (step 150), and if the request data is not read from the terminal unit 2 _m , the read frequency data Dt is set to 1 (step 151). Read frequency data D
As shown in FIG. 10, t is written in the request data area together with the terminal number data At, music title data Bt and requester data Ct. After obtaining the read frequency data Dt, 1 is added to the variable t (step 152) and 1 is added to the variable m (step 153). On the other hand, if the request data is not supplied from the terminal unit 2 _m, it is determined whether or not the non-request data is supplied (step 15
4) Step 1 if unrequested data is supplied
Continue to 53. Also, in step 144, the terminal area 2 _m
Also when it is determined that is not in use, the process proceeds to step 153. After adding 1 to the variable m in step 153, it is determined whether or not the variable m is larger than the number of terminals n (step 155). If m ≦ n, the process proceeds to step 144 and m> n.
If so, this routine ends. By the process of reading requests routine, if the request at each terminal unit 2 ₁ to 2 _n, written in the request data area of the reading order in the RAM16 terminal number, request Song, as large and small data requestor name and reading frequency Be done.

If the request data is not supplied and there is no response to the request read command without determining whether the terminal unit 2 _m is in use, the terminal unit
2 _m may be unused.

In the request performance order determination routine, as shown in FIG. 6, first, the variable q is made equal to the value of the variable s (step 171), and the variable p is made equal to the value of the variable r (step 172). Both variables s and r have an initial value of 1 when the power is turned on.
Is set to. The variable s in step 171 indicates a value obtained by adding 1 to the request data number that defines the performance order of the request data area up to the last routine process. The variable r in step 172 indicates a value obtained by adding 1 to the final number of the performance order defined in the previous routine processing. After setting the variables q and p, it is determined whether or not the sth data is written in the request data area (step 173). If the sth data is written, the sth data in the request data area is determined. The read frequency data Ds is read and it is determined whether the read frequency data Ds is equal to 1 (step 174). If Ds = 1, it is the request data from the terminal section with a relatively low request frequency, so in order to respond to the request with priority, the terminal number data As, the song name data Bs, and the requester data from the sth position in the request data area.
Cs is read (step 175), and the terminal number data As, the song title data Bs, and the requester data Cs are written in the rth position of the performance order area (FIG. 12) formed in the RAM 16 (step 176). Then, 1 is added to the variable r (step 177), and 1 is added to the variable s (step 178).
On the other hand, if Ds = 0, it means that the request data is from a terminal unit having a relatively high request frequency, and therefore the process proceeds to step 178 to search for request data from a terminal unit having a low request frequency. After the execution of step 178, it is determined whether or not the value obtained by subtracting the variable q from the variable s is a predetermined value x or more (step 179). The predetermined value x indicates the maximum number of requests for which the performance order should be determined each time this routine is processed. If sq <x, the process returns to step 173, and if sq ≧ x, the performance order for the request from the terminal section with a relatively low request frequency is determined, so that the performance from the terminal section with a relatively high request frequency is determined. The process moves to step 180 to determine the performance order of the request data. Also, in step 173,
If it is determined that the data has not been written to the sth position of the request data area, the number of requests s or more has not been read.

In step 180, the variable s is made equal to the variable q, and the process goes to steps 181-186. The steps 181 to 186 find the request data from the terminal section having a relatively high request frequency and determine the performance order, and the other steps are the same as the steps 173 to 178.

After execution of step 186, it is determined whether or not the value obtained by subtracting the variable p from the variable r is equal to or greater than the predetermined value x (step 18).
7). If r−p <x, the process returns to step 181, and r−p ≧
If x, the processing of this routine is completed. Step 181
If it is determined that the data has not been written to the sth position in the request data area, the request has not been read in the number s or more, and thus the processing of this routine ends. By the processing of the request performance order determination routine, for example, as shown in FIG. 11, terminal number data, music title data, and requester data are written in the performance order area from a terminal section having a relatively low request frequency.

Next, in the performance routine, as shown in FIG. 7, first, it is judged whether or not the variable r is larger than the variable u (step 200). The variable r indicates the number of requests for which the playing order has been determined, and the variable u indicates the number of requests for playing in accordance with the playing order. Therefore, if r ≦ u, there is no request in the playing order that has not been played. The variable v is set to 1 (step 201) and the execution of this routine ends. On the other hand, if r> u, there is a request to wait for the performance order that has not been performed, so it is determined whether the flag F ₁ is equal to 1 (step 202). If F ₁ = 0, it means that the music is not being played. Therefore, the terminal number data Au, the music title data Bu and the requester data Cu of the u-th piece of music are read out from the performance order area of the RAM 16 (step 203) and the automatic change disk player 3 is read. The read song name data Bu is supplied (step 204), and performance start command data including the song name data Bu and requester data Cu is output to the terminal portion of the read terminal number data Au (step 205). . The performance start command data is supplied to the terminal section of the terminal number Au read from the input / output interface 12, and in the terminal section supplied as described above, the next performance song name and requester name are displayed on the CRT monitor 27 to request. Prepare to sing to others. After execution of step 205, it is determined whether or not a predetermined time T _{1 has} elapsed (step 20
6), Step 205 is executed until the predetermined time T ₁ elapses. This predetermined time T ₁ is longer than the performance start preparation time required by the automatic change disc player 3. When a predetermined time T _{1 has} passed, a performance start command is issued to the auto change disc player 3 (step
207), the flag F ₁ is set equal to ₁ to indicate that the performance has started (step 208), and this routine ends.

If F ₁ = 1 in step 202, it means that the performance has been started, so it is determined whether or not the flag F ₂ indicating whether the background music is being played is equal to 1 (step 209). If F ₂ = 0, it means that the requested song has started playing, and the auto change disc player 3
It is determined whether or not a performance end command is supplied from (step 210). When the performance end command is supplied, the memory cancel data described above is output to the terminal part of the terminal number (step 211). Then, 1 is added to the variable u (step 212), the performance is finished, the flag F ₁ is reset to 0 (step 213), 1 is added to the variable v (step 214), and the variable v is set to a predetermined value. It is determined whether it is larger than y (step 215). Variable v
Is a variable for multiplying the predetermined value y, and is set to an initial value of 1 when the power is turned on or at step 218, and the predetermined value y indicates the number of songs to be continuously played in response to a request. v
If ≦ y, the process proceeds to step 200, and if v> y, the requested music is continuously played by the predetermined value y, so the background music performance start command is automatically issued to take a break for the predetermined time T _2. This occurs for the change disc player 3 (step 216). Then, the flags F ₁ and F ₂ are set to 1 to indicate that the background music performance has started (step 217) and the variable v is set.
Is set equal to 1 (step 218), and the execution of this routine ends.

In step 209, if F ₂ = 1, since it is being played in the background music, the time a predetermined time T ₂ to determine whether to play background music (step 219), the predetermined time T ₂ When the background music is played for the time, a background music playing stop command is issued to the auto change disc player 3 (step 220), and flags F ₁ and F are given.
Reset ₂ to 0 (step 221) and go to step 200 to respond to the request. This predetermined time T
₂ may be a fixed time, but may be a time equal to the playing time of one background music. Further, when the background music is not played for the predetermined time T ₂ in step 219 and the background music cancellation command is issued by a key operation or the like, the process may proceed to step 220.

The requested song played may be stored in the auxiliary storage device 20 together with the playing order.

In the automatic change disc player 3, when the central control unit 1 supplies song title data as a song designation command, the disc 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 specified request song. When a performance start command is supplied from the central control unit 1, the disc rotates and the pickup optically reads out music information from the disc, for example, and a reproduction processing circuit (not shown) outputs a video signal and a 2
The audio signal of the channel is obtained. Video signal is CR
The lyrics and pictures of the requested song are supplied to the T monitor 31, and the audio signal is supplied to the speaker device 33 through the amplifier 32, and the melody of the requested song flows.
Then, when the performance of the designated request music is completed, 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 returned to the predetermined storage position. Is performed.
Further, when a background music performance start command is supplied from the central control unit 1, a predetermined disc is selected and set at a predetermined performance position, and the pickup is randomly moved from the rest position to the performance position of the music and the background is played. When the music performance is started and the background music performance stop command is supplied, the rotation of the disc is stopped and the pickup is returned to the rest position, and the disc is returned to the predetermined storage position, similarly to the end of the performance of the requested song. Is done.

Here, the disc to be used is not limited to a disc manufactured by already including character information such as lyrics in image information, but also a disc in which image information and character information are recorded independently. When the latter disc is used, for example, only the lyrics information or the image information including the lyrics information is sent as a video signal to the terminal section where the request originator of the song being played is present, while the other terminals include the lyrics information. It is possible to perform complicated processing such as sending non-existing video information as a video signal. That is, only the lyrics information for each terminal part,
Either the image information alone or both the lyrics information and the image information can be arbitrarily sent from the central control unit 1 and displayed.

On the other hand, the request data transmission routine is as shown in FIG.
This is an interrupt routine that is processed when each request command is supplied as shown in (b). In this request data transmission routine, when a request command is supplied, the request command is a request performance order list request command, a song information request command during performance, a song name list request command by genre, a song name list request command by artist, and a Japanese syllabary. It is determined which one of the order-by-order song name list request commands (steps 231 to 235). If the request command is the request performance order list request command, the variable i
Is equal to the variable u (step 236), the song name data of the i-th song is read from the performance order area in the RAM 16, and the song name data is output to the requested terminal section (step 237), and 1 is added to the variable i. Then (step 238), it is determined whether or not the variable i is larger than the predetermined value z (step 239). If i ≦ z, the process proceeds to step 237, i> z
If so, this routine ends. Therefore, the requested performance order data composed of z number of music title data including the currently played music title data is supplied to the requested terminal unit and the requested performance order is displayed on the CRT monitor of the terminal unit.

If the request command is a song information request command during performance, RA
The song title data of the u-th song is read from the performance order area in M16 (step 240), 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 241). When the request command is a song name list request command, a song name list read command for each genre of songs, enka, new music and rock, a song name list read command for each artist, and a song name list read command for each syllabary order are stored in the auxiliary storage device 20. It occurs in response (steps 242-244). The auxiliary storage device 20 reads and outputs the corresponding music content data or music name 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 and output the music content data or the music title list data (step 245). If the data has been read and output, the data is requested. The output is relayed to the terminal unit (step 246). 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, the image information on the CRT monitor 27 or CRT monitor 31 of the terminal portion 2 ₁ to 2 _n any time based on the command of the microprocessor 11 Is sent. As a result, all the requests from the terminal units 2 ₁ to 2 _{n have} been responded to,
Information such as a commercial message (for example, information indicating that a request is being received) or a simple background image is displayed on the CRT monitor 27 or in a request waiting state or when some free time is generated due to a disc exchange of the auto change disc player 3 or the like. Can be projected on 31.

In the above-described embodiment, the central control unit 1 and the terminal units 2 ₁ to 2 _n are connected by a cable or the like to perform wired communication, but the central control unit 1 and the terminal unit 2 ₁ 2
It may be carried out wireless communication by providing each other wireless transceiver between to 2 _n.

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 result to the printer 19, or the auxiliary storage device. It may be stored in 20.

Further, the requester data does not have to be the request sender name itself, but may be at least the content of the terminal number or higher, for example, the character of the alphabet A.
Further, the requester data may not be requested unless particularly required.

Further, in the above-mentioned embodiment, the automatic 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.

Further, in the above-described embodiment, the case where the operation as the automatic music selection performance device is shared by the central control unit 1 and the terminal units 2 ₁ to 2 _n has been described, but each terminal unit is, for example, in the case of the terminal unit 2 _1. Only the keyboard 26, the CRT monitor 27, the bar code reader 28 and its input / output interface 23 are connected, and the input / output interface 23 and the input / output interface 12 of the central control unit 1 are connected so that all operations are performed by the microprocessor of the central control unit 1.
