  It should be noted that the usage time can be set at the store side when the user enters the store.
[0037]
  Next, when the music selection button 66 of the transmitter 60 is pressed, the music selection is enabled, and then the numeric key 68 is pressed to input the music number of the music to be sung. At this time, each time the numeric key is pressed, the symbols A, B and 0-9 of the pressed key are displayed on the liquid crystal display 62, the CRT 12, 14 and the music number display 25 of the control device 20, and You can check it.
  Note that the fact that the music is being selected can be confirmed by blinking the displayed code.
[0038]
  When the input of the song number is completed and the performance button 64 is pressed, the entered song number is confirmed, and the song number display disappears after the blinking stops, and the CPU 37 transmits the song data corresponding to the song number. A request is made to the host computer 84. Then, the host computer 84 reads out the telephone number stored in the ROM 39 and confirms whether the telephone number is a contracted regular one. After the confirmation, the requested song data is The data is received from the host computer 84 via the telephone line 31, converted into data that can be processed by the CPU 37 by the communication modem 42, and stored in the hard disk memory 43.
[0039]
  Subsequently, the music data is read from the hard disk memory 43, and the MIDI data included in the music data is input to the audio control circuit 44 and written to the sound source data corresponding to the MIDI data. By this writing, the sound source data output from the MIDI sound source 441 is converted into an analog music signal that can be amplified by the amplifier 16.

  That is, the user can sing (karaoke) the selected song through the microphone 81 or the microphone 82 while watching the background video 200 and the lyrics video 202 displayed on the screens of the CRTs 12 and 14.
[0042]
  Next, the reserved music performance control by the CPU 37 will be described with reference to the flowcharts of FIGS.
  First, the composition of music data will be described with reference to FIG. As shown in FIG. 5, the song data 100 includes song data D1 composed of MIDI data, lyrics video data, and the like, maximum value data of the cue time of the song (the time required to play after selecting the song data 100) Data indicating the maximum value) t1, total performance time data (data indicating the time required to play all the song data 100) t2, prelude time data (data indicating the time required to reproduce the prelude portion) t3, 1 Performance time data (data indicating the time required to reproduce the portion showing the first song) t4, interlude time data (data indicating the time required to reproduce the interlude portion) t5, second performance time data (number 2) (Data indicating the time required to reproduce the portion indicating the song of No. 3)) t6, time data after the third (data indicating the time required to reproduce the portion subsequent to the portion indicating the song No. 3) t7 and Postlude time data composed of t8 (data indicating the time required to play the postlude portion).
[0043]
  As shown in FIG. 6, the CPU 37 performs control (step 100) for playing the selected music (step 100) and calculation of the remaining usage time (step 300) when the performance is finished (step 200). The main processing content is that the remaining usage time is calculated according to the steps shown in FIG.
  First, the end time data stored in the EEPROM 52 is read (step 310), the current time data is read from the real-time clock 41 (step 320), and the end time data is subtracted from the read current time data to obtain the remaining usage time. R is calculated (step 330).
[0044]
  Subsequently, it is determined whether or not the usage time R is the start time of 20 minutes or less previously stored in the EEPROM 52 (step 340), and if it is 20 minutes or less, the music of each reserved song stored in the EEPROM 52 is determined. Is read out (step 350), and the total performance time Ta of all reserved songs is calculated based on the read total performance time data t2 (step 360).
  That is, the total performance time Ta of all reserved songs is calculated by adding the total performance time data t2 of each reserved song. For example, when there are five reserved songs and the total performance time data t2 of the first song from the total performance time data t2 of the first song is 5 minutes, 5 minutes, 6 minutes, 7 minutes, and 4 minutes, respectively. The total performance time Ta of all reserved songs is (5 minutes + 5 minutes + 6 minutes + 7 minutes + 4 minutes) = 27 minutes.
[0045]
  Next, the time required to cue each reserved song is the total performance time of all the reserved songs calculated above.InThe total reserved music completion time Tb required to complete the performance of all the reserved music is calculated by addition (step 370).
  That is, the maximum value data t1 of the cue time for each reserved song is added for the number of reserved songs, and the calculated total performance time Ta of all the reserved songs is added to the added value. For example, if the head search time of each song is the same 3 seconds, in the above example, the total reserved song completion time Tb = (3 seconds × 5) +27 minutes = 27 minutes 15 seconds.
[0046]
  Subsequently, it is determined whether or not the calculated all-reserved song completion time Tb is 20 minutes or more (step 380). That is, it is determined whether the five reserved songs can be completed within 20 minutes of the remaining usage time. Next, when not playing (step 390), the CRT 12 and 14 say, “The remaining time is less than 20 minutes. There is not enough time to play all the reserved songs from the beginning. The next song cannot be played within the remaining time.To play from the beginning until the time is up, press “Yes” on the transmitter, or press “No” to cut a part of the song and play all songs Please give me. Is displayed (step 400).
[0047]
  Here, when the selection button 76 indicating "Yes" is pressed, the CRTs 12 and 14 display "All songs playing mode will be entered and cannot be reserved" (step 420), and all songs playing the reserved songs are played. The process is shifted to the mode (step 430).
  In other words, when the end time may be reached in the middle of a reserved song, the reserved song can be played from the beginning until the end time is reached by selecting the all-music performance mode.
[0048]
  On the other hand, if the selection denial button 77 indicating “NO” is pressed in step 410, that is, if the all-music performance mode is not selected, the end time stored in the EEPROM 52 is skipped to step 440 shown in FIG. Data is read and current time data is read (step 450). Then, the remaining time R is calculated (step 460), the follower time data t8 of each reserved song is read from the EEPROM 52, and the total completed time T1 is calculated when all the reserved songs are cut off from the subsequent part. (Step 470).
  That is, a value is calculated by subtracting the sum of the follower time data t8 of each reserved song from the total reserved song completion time Tb. For example, when the ending times of the first to fifth songs of the reserved songs are 30 seconds, 20 seconds, 25 seconds, 30 seconds, and 30 seconds, respectively, 30 seconds + 20 seconds + 25 seconds + 30 seconds + 30 seconds) = 2 minutes 15 seconds.
  Therefore, the total completion time T1 = 27 minutes 15 seconds−2 minutes 15 seconds = 25 minutes.
[0049]
  When the remaining usage time R is longer than the total completion time T1, that is, when all the reserved songs that have been cut off after the remaining usage time can be completed (step 480), the CRTs 12 and 14 indicate “ All tunes will be cut and played "(step 490), and the process proceeds to the posterior cut mode for cutting and playing the posterior portion of each reserved song (step 500).
  In this way, everyone who has reserved a song can sing equally by cutting the later performance part.
[0050]
  In the above example, since the total completion time T1 (25 minutes) is longer than the remaining usage time R (20 minutes), the process proceeds to step 510 and the total completion time when all of the reserved songs are cut from No. 3 and beyond. T2 is calculated.
  That is, a value is calculated by subtracting the total of the time data t7 from the third and subsequent times of each reserved music from the total reserved music performance time Tb. For example, if the time data t7 from the third song on the first song to the fifth song of the reserved song is 1 minute 30 seconds, 1 minute 20 seconds, 2 minutes, 1 minute 50 seconds, 1 minute 15 seconds, respectively, the reserved song The total of the time data t7 and thereafter is (1 minute 30 seconds + 1 minute 20 seconds + 2 minutes + 1 minute 50 seconds + 1 minute 15 seconds) = 7 minutes 55 seconds.
  Therefore, the total completion time T2 = 27 minutes 15 seconds−7 minutes 55 seconds = 19 minutes 20 seconds.
[0051]
  Subsequently, when the remaining usage time R is longer than the total completion time T2, that is, when all the reserved songs cut after the third in the remaining usage time can be completed (step 520), the CRTs 12 and 14 indicate “ This will cut and play the third and subsequent songs of all the songs. "Is displayed (step 530), and the process proceeds to the third and later cut mode processing where the third and subsequent songs of each reserved song are cut and played. (Step 540). In the above example, since the total completion time T2 (19 minutes 20 seconds) is shorter than the remaining usage time R (20 minutes), the process proceeds to step 530 and step 540, and shifts to the third and subsequent cut mode processes.
  In this way, all those who have reserved a song can sing equally by cutting the third and subsequent songs.
[0052]
  On the other hand, if the total completion time T2 is longer than the remaining usage time R in step 520, that is, if all of the reserved songs are played after cutting No. 3 and later, the total usage time is within the remaining usage time. If the performance cannot be performed, the process proceeds to step 550 shown in FIG. 9 to calculate the total performance time T3 when all the reserved songs are preluded and the third and subsequent pieces are cut.
  That is, a value is calculated by subtracting the total value of the prelude time data t3 of each reserved song and the total value of the time data t7 and subsequent times from all the reserved song completion times Tb.
[0053]
  Subsequently, when the calculated total playing time T3 is shorter than the remaining usage time R (step 560), the CRTs 12 and 14 are set to “play all songs from this and cut the third and subsequent songs. ”Is displayed (step 570), and the process shifts to the prelude and the third and subsequent cut modes in which each reserved song is played by cutting the prelude part and the third and subsequent pieces (step 580).
  In this way, everyone who has reserved a song can sing equally by cutting the prelude part of the song and the third and subsequent songs.
[0054]
  In addition, even if the total completion time T3 is longer than the remaining usage time R in step 560, that is, even if the prelude portion of each reserved music and the third and subsequent songs are cut, all reserved music will be used within the remaining usage time. If the performance cannot be performed, the process proceeds to step 590, where the total completion time T4 is calculated when all the performance parts of the reserved music are the prelude and the first.
  That is, a value obtained by adding the total value of the prelude time data t3 of each reserved music and the total value of the first performance time data t4 is calculated.
[0055]
  Subsequently, if the calculated total playing time T4 is shorter than the remaining usage time R (step 600), the CRTs 12 and 14 will “play all the preludes and only the first. Is displayed (step 610), and each reserved song is transferred to the prelude portion and the first performance mode only (step 620).
  In this way, everyone who has reserved a song can sing equally by playing only the prelude part of the song and No. 1.
[0056]
  Further, in step 600, when the total completion time T4 is longer than the remaining usage time R, that is, when each reserved song is played only in the prelude part and No. 1, all the reserved songs are within the remaining usage time. If it cannot be performed, the process proceeds to step 630, and the total completion time T5 is calculated when all the preludes of the reserved music are cut to be only No. 1.
  That is, a value obtained by adding the total value of the first performance time data t4 of each reserved music is calculated.
[0057]
  Subsequently, when the calculated total playing time T5 is shorter than the remaining usage time R (step 640), the CRTs 12 and 14 are set to “play all songs from the first pre-cut only. "" Is displayed (step 650), and only the number 1 of the prelude cut that plays only the number 1 of the prelude portion of each reserved music is shifted to processing of the performance mode (step 660).
  In this way, all those who have reserved a song can sing equally only the number 1 that cut the prelude part of the song.
[0058]
  In addition, even if the total completion time T5 is longer than the remaining usage time R in step 640, that is, even if each reserved song is played only in the first cut of the prelude, all the reserved songs are within the remaining usage time. If the performance cannot be performed, the process proceeds to step 670, where the remaining usage time R is divided by the number of reserved songs to calculate a performance time tc per song. Subsequently, the CRTs 12 and 14 display "All songs will be played only for tc time" (step 680), and the process shifts to the tc time performance mode processing for playing each reserved song for tc time (step 680). 690).
  In this way, all those who have reserved a song can sing equally by tc time.
[0059]
  As described above, according to the karaoke apparatus of the present embodiment, when the remaining usage time decreases, all the reservation persons sing equally so that no person who cannot sing the reserved song appears. Can be able to. In addition, if all of the reserved songs are played from the beginning of the song and do not fit within the remaining usage time, a portion of the song can be cut and everyone can sing equally. In this case, you can decide the priority to cut the part to be cut, such as the posterior part of the song, the third and later, the prelude part and the third and later, and avoid singing important parts of the song as much as possible. You can keep singing fun.
[0060]
  The song data 100 includes chorus part performance time data t9 indicating the time required to play the characteristic portion of the song, the so-called chorus portion. For example, in step 670 of the above embodiment, each reserved song The total value of the chorus partial performance time data t9 is calculated, and in step 680, the CRTs 12 and 14 display "All songs are played only from the chorus part." In step 690, each reserved song is chorused. It can also be configured to shift to the process of the chorus partial performance mode in which only the portion is played. In addition, the priority order of the portions to be cut in the reserved music is not limited to the above embodiment, such as the music sequel, the third, the second, the third, and the sequel.

【The invention's effect】
  As described above, according to the present invention, when the remaining usage time reaches a certain time, the reserved song can be sung at least a part of the song. Give equal opportunity to sing to all who bookKaraoke equipmentCan be realized.
  In addition, since a song that cannot be reproduced within the above usage time can be notified, it is possible to know who has reserved the song that cannot be reproduced. This allows you to decide how to give up playing, or how to use the remaining usage time, such as when a person who has made a reservation to play within the remaining time gives up playing the song to a person who knows that it cannot play within the above usage time. Can be decided.
  Furthermore, if the reserved music cannot be completed within the remaining usage time, first, it is determined whether the predetermined section of the reserved music is cut, and whether it falls within the usage time. Sections can be added sequentially.
  Therefore, since the important part in a song can be sung as much as possible, a singer's satisfaction can be heightened rather than singing from the head of a song and being interrupted on the way.
