In the automatic music selection playing apparatus having such a configuration is stored in each terminal unit 2 ₁ RAM 25 request songs in ~2n i.e. it accepts designation song information in order. On the other hand, the central control unit 1 inputs the requested music pieces stored in the RAM 25 in each of the terminal units 2 _{1 to} 2n in a predetermined order, determines the performance order by a method described later, and controls the automatic change disc player 3 in accordance with the performance order. And respond to the request. In addition, each terminal section 2 _{1 to} 2n
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 of "1. song name list", "2. song contents information being played" and "3. request playing order" to be 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 is operated (step 5
8) If the selection key is operated, the content corresponding to the cursor position is read (step 59), and it is determined whether the song name list, the song content information being played, or the requested playing order is selected. (Steps 60-62). If the song title list is selected, the process proceeds to step 65. If the music content information being played is selected, a music content information request command for the performance is issued (step 63), and if the request performance order is selected, a request performance order list request command is generated (step 63). 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, the predetermined genre classification display data is input / output interface 23 to request the genre classification designation.
(Step 71). Input / output interface 23
CR the video signal according to the specified genre classification display data
It is supplied to the T 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 songs, enka, new music, and rock is selected (step
74-77). According to the discrimination result, a music title list request command for any one of genre of song, enka, new music and rock is generated (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's name is entered, the requester's 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 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 assigned to the song name. Read as data (step 100), go to step 93 and enter R
The read song title data and requester data are stored in the request song area formed in AM25.

When it is determined in step 55 that the request display key has been operated, all the song title data DA1 ₁ , DA1 ₂ ... Stored in order from the first song in the request song area in the RAM 25 are read (step 97), and the respective read song titles are read. Display data corresponding to data is input / output interface 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 / 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 11).
1). 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). This gives C
The requested song name list is displayed on the RT 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 content data being played is output to the input / output interface 23 as display data (step 119). As a result, the CRT monitor 27 displays song content information such as the song title and lyrics of the song being played. This display format is, for example, a song title, a composer's name, a poet's name, a professional singer, and a lyrics, which can be scrolled and viewed by operating the arrow keys. 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). This allows the CRT monitor
At 27, the current order of requested performances is displayed. 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, song name data D
Erase A1 ₁ and requester data DB1 ₁ and DA1 ₂ to DA1 ₁
In addition, the request order is advanced so that DB1 ₂ becomes DB1 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, as shown in FIG. 4, it is judged whether or not the song title data is stored in the requested song area in the RAM 25 (step 131), and if the song name data is not stored in the requested song area, Outputs unrequested data to the input / output interface 22 to supply it to the central controller 1 (step 132). If the song title data is stored in the requested song area, song title data and requester data are read in order from the first song in the requested song area (step 133), and the read song title data and requester data are used as terminal number data. At the same time, the request data is sequentially output to the input / output interface 22 so as to be supplied to the central control unit 1 (step 134). Then, a predetermined number A (for example,
It is determined whether or not the request data has been sent out only 2) (step 135). If the predetermined number A is not reached, the process returns to step 114 to read the next title of music title data and requester data. When the number reaches the predetermined number A, the process returns to the routine being processed. When the song title data and the requester data are sent to the central control unit 1, the central control unit 1 is notified of the start and output of the data by a control signal. If the number of requested music pieces does not reach the predetermined number A, only the requested number of music pieces 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 2n 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 stored (step 136), and 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 at which the specified mode for reading the request from only the specified terminal section is performed
Is read (step 138) and the variable x is made equal to the read frequency y (step 139). The frequency y is, for example,
The terminal number can be stored at a predetermined position in the RAM 16 at the same time when the key operation is performed to store the terminal number in the designated terminal area. After executing step 139, it is determined whether or not the variable x is equal to 1 (step 14
0). If x ≠ 0 is determined in step 137, 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 2n (step 141), x ≠
If it is 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 section 2m is in use (step 144). For example, "in use" means that the terminal unit 2m is in a power-on state. Whether the terminal units 2 _{1 to} 2n are in use or not in use is controlled by the central control unit 1.
In, for example, it is set by a user by operating a key or the like. If the terminal section 2m is in use, the terminal section
A request read command is generated for 2 m (step 145). Terminal portion 2m output interface from output interface 12 by the control signal requests reading command is fed to the output interface 12 (in the case of the terminal unit 2 _1, input-output interface 22)
Is supplied to. After the request read command is issued, it is determined whether the request data including the terminal number data, the song name data, and the requester data is supplied from the terminal unit 2m (step 146). If the request data is supplied, the request is sent. The data is read (step 147) and written in the 2m request music area in RAM 16 (step 148). Then, it is determined whether or not all the request data of the predetermined number A supplied from the terminal section 2m have been read (step 149), and when all the request data from the terminal section 2m have been read, the variable m
Is incremented by 1 (step 150). On the other hand, if the request data is not supplied from the terminal portion 2m, it is determined whether or not the non-request data is supplied (step 15
1), if unrequested data is supplied, step 1
Go to 50. In step 144, the terminal area 2m
Also when it is determined that is not in use, the process proceeds to step 150. After adding 1 to the variable m in step 150, it is judged 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 and m> n.
If so, this routine ends. By the process of reading requests routine, each at most request Song and request name of the predetermined number A is written as data into 2 ₁ to 2n request song area in RAM16 Once the request at each terminal unit 2 ₁ to 2n . In addition, the 2 _{1 to} 2n request song area in RAM 16 is the area of each terminal 2 _{1 to} 2n.
It is formed in the same way as the request song area in RAM25, but the terminal number is also stored.

In the case of the designated mode subroutine, the variable w is set equal to 1 (step 153), the wth terminal number stored in the designated terminal area is read as the number m (step 154), and the process proceeds to step 155. Steps 155 to 160 are the same operations as steps 144 to 149. Therefore, when all the request data supplied from the terminal section 2m is read in step 160, it is determined whether all the terminal numbers stored in the designated terminal area have been read (step 161), and all terminal numbers are read. 1 for variable w if not
Is added (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. Also step
If the request data is not supplied from the terminal portion 2m in 157, it is determined whether or not the non-request data is supplied (step 163), and if the non-request data is supplied, the process proceeds to step 161.

If not the terminal unit designated be stored request data at each terminal unit 2 ₁ to 2n in this specification mode, 2 ₁ to 2n request song Request Song and requester name to the area it is not written in the RAM16 Of.

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, when the read frequency y is 1, x = 1, so normal mode is executed and all terminal units are executed.
2 Read requests from _{1 to} 2n. Further, when the read frequency y is 2, x = 2. Therefore, in the first processing cycle, the request is read from the terminal unit with the specified terminal number in the specified mode, and in the next processing cycle, x = 1. read requests from all the terminal sections 2 ₁ to 2n in the normal mode, since the further the x = 0, at the next processing cycle, reload the frequency y.
Therefore, when request data is read in the specified mode,
It is possible to increase the frequency with which the requested song of the designated terminal section is played.

The terminal number of the designated terminal area in the RAM 16 and the frequency y at a predetermined position are written 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 screen of the CRT 18, and the "?" Input the number, and write the terminal number input by operating the setting key to the designated terminal area in RAM16,
In addition, the frequency is written in a predetermined position. The frequency y is an integer of 1 or more, 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.

Alternatively, 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 is performed by the keyboard 17
An interrupt is processed by operating the setting key of. In the request performance priority setting routine, as shown in FIG. 6, first, predetermined performance priority setting display data is output to the input / output interface 14 to make a request performance priority specification request (step 165). The input / output interface 14 supplies the video signal according to the predetermined performance priority setting display data to the CRT monitor 18, and "Priority 1:?" And "Priority 2:?" Are displayed on the screen of the CRT monitor 18. It is displayed as ……. For example, the user can use the keyboard in the "?"
By the operation of the 17 numeric keys to enter the terminal number to be played in favor of the request of the terminal part 2 ₁ ~2n. This does not need to prioritize for all of the terminal portion 2 ₁ to 2n, 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. Yes (step 167). This allows CRT
The number corresponding to the operated numeric key is displayed as the terminal number to be played preferentially in the "?" Part on the screen of the monitor 18. Then, it is determined whether or not the setting key is operated (step 168), and if the setting key is operated,
The input terminal number data of each priority is read from the first (step 169), and the RAM is read as shown in FIG.
Writing is performed in order from the first in the performance priority area formed in 16 (step 170).

Therefore, by the processing of this request performance priority setting routine, the terminal numbers are stored in the performance priority area in the RAM 16 in the order of priority setting, and the terminal numbers without priority setting are set randomly or in the order of request transmission. If the request performance priority setting routine is not processed, this performance priority area is initially set in the order of terminal number or request transmission order. Further, when the cancel key is operated in steps 166 and 168, this routine may be ended.

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, if the terminal number with the first priority is n-8, then m = n-8. When the requested song name is written in the 2m requested song area, the song name data and requester data of the first song in the 2m requested song area are read (step 174), and the performance formed in the RAM 16 as shown in FIG. 13 is performed. It is written together with the terminal number data at the t-th music in the turn area (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 the variable s is larger than the number of terminals n (step 178), and s≤
If n, the process returns to step 172, and if s> n, the process of this routine ends. By the processing of this request performance order determination routine, a total of t request music pieces are written in the performance order area in the performance order. The request performance order determination routine is processed each time the request read routine is executed, but it may be processed subsequently 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, it is possible to set the performance order to the request order, a completely random order, or an order with 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), and when the performance key is operated, the variable u is set to 1. Equalize (step 181), read the terminal number data, song title data and requester data of the u-th song from the performance order area of the RAM 16 (step 182),
The read music title data is supplied to the auto change disc player 3 (step 183), and performance start command data including the music title data and 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 part of the terminal number read from the input / output interface 12, and in the terminal part supplied as described above, the name of the next performance song and the requester's name are displayed on the CRT monitor 27 and the requester Provoke the preparation for singing to. After executing step 184, it is determined whether a predetermined time has elapsed (step 185), and step 184 is executed until the predetermined time elapses. This predetermined time is longer than the performance start preparation time supplied in the automatic change disc player 3. When a predetermined time has elapsed, a performance start command is issued to the automatic change disc player 3 (step 186), and this routine is ended.

When the performance key is not operated in step 180, it is determined whether or not a performance end command is supplied from the automatic 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 it is determined whether or not the variable u is larger than the variable t, that is, the number of pieces of music stored in the playing order area (step 190). u ≦ t
If so, the routine proceeds to step 182, and if u> t, this routine is ended and the routine proceeds to the request performance order determination routine. After the performance order is newly determined in this request performance order determination routine, the process may proceed to step 181 without operating the performance key. 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 song designation information, the disc on which the song indicated by the data is recorded is selected from a predetermined storage position and set in a predetermined playing device. , 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-channel audio signal. A signal and a music content data signal of music content character information are obtained. The video signal is supplied to the CRT monitor 31 to display the lyrics and pictures of the requested song, and the audio signal is supplied to the speaker device 33 via 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. The music content data signal is supplied to an input buffer (not shown) in the input interface 13 and sequentially held temporarily. The microprocessor 11 determines whether or not the music content data is held in the input buffer during the performance (step 19).

It is determined which one of the music order list request commands by tone order is issued (steps 201 to 205). When the request command is the request performance order list request command, the variable v is made equal to the variable u (step 206), the music title data of the vth music is read from the performance order area in the RAM 16, and the requested music title is given to the terminal section. Data is output (step 207), 1 is added to the variable v (step 208), and it is determined whether or not the variable v is larger than the numerical value t (step 209). If v ≦ t, the process proceeds to step 207 and v>
If t, this routine ends. Therefore, the requested performance order data composed of the 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 request command for the music content information being played, the music content data is read from the music content data area in the RAM 16 (step 210) and the read data is output to the requesting terminal unit (step 210). 211). If the request command is a song name list request command, the song, enka,
Auxiliary storage device for song name list read command by genre of new music and rock, song name list read command by artist and song name list read command by 50-sound order
It occurs for 20 (steps 212 to 214). The auxiliary storage device 20 reads and outputs the corresponding music 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 and output the song title list data (step 21
