The data read by the optical pink-up 16 is a high frequency analog signal. Here, the data recorded on the disk 12 will be explained with reference to FIG. FIG. 3 shows an outline of the track 18 on which data is recorded, and it is actually formed in a spiral shape on the surface of the disk 12. A lead-in area 20 and a lead-out area 2 indicate the beginning and end of the track 18, respectively.
2 is provided.

A system reserve area 24, a disc label area 26, a bus table area 28, and a directory area 30 are arranged after the lead-in area 20, and these areas are system areas occupied by the CD-I player system. After the system area, an index area 32, a name file area 34, and a data area 36 are arranged. These areas are called program areas and are areas that users can use freely.

The index area 32 has a data area 36 which will be described later.
The physical address, etc. of each data within is recorded. In the name file area 34, an identification code of data in the data area 36 is recorded.

The data in the data area 36 is AD-PCM (A-da
pt(ve 1)elta-Pulse Code
The information is recorded by signal processing using a modulation method, and the data area 36 is time-divided into eight channels. In other words, in the diagram showing a part 36a of the data area 36 in FIG. 3, the numbers 1 to 8 indicate each channel. For example, if only the signal corresponding to "l" is reproduced, This is a recording method that allows you to obtain data. Note that the control unit 10 controls the index area 32
data area 3 by referring to the physical address in
6. Random access (including index sequential access) is possible. In this embodiment, the first to eighth channels are assigned to the first, third, fifth, and seventh channels, and the second channel is assigned to the score channel.
In the channel, audio data corresponding to the musical score data recorded in the first channel is recorded in synchronization with the musical score data. Similarly, the fourth channel has audio data corresponding to the score data of the third channel, the sixth channel has audio data corresponding to the score data of the fifth channel, and the eighth channel has sound data corresponding to the seventh channel. Acoustic data is recorded. That is, the second, fourth
, the sixth and eighth channels are assigned to the audio channels.

In FIG. 1, 38 is a digital processing section, which removes noise, corrects the phase, etc. of the analog signal sent from the control section 10, and converts it into a digital signal.

Reference numeral 42 denotes an input key, which is used to select the name of a piece of music for which a musical score is to be printed from the list of song names displayed on the display 44, and to input other instructions to the production section 10.

Reference numeral 45 denotes a fee detection unit that determines whether an appropriate fee has been charged and sends the result to the control unit IO.

Note that the control section 10, disk 12, motor 14, optical pickup 16, and digital processing section 38
Compact Disk-Interactive)
A playback section of the system is configured.

Reference numeral 40 denotes a distribution section, which includes a microprocessor (not shown) and a distribution circuit (not shown) controlled by the microprocessor.

The contents of the data area 36, which have been converted into digital signals, are sequentially sent from the digital processing section 38 to the distribution circuit. The microprocessor in the distribution section 40 distributes this digital signal into a music score channel and an audio channel.

Next, the audio output section connected to the audio channel output side of the distribution section 40 will be explained.

A decoder 46 decodes the digitized audio data signal sent from the distribution section 40.

60 is a digital to analog converter (D/A converter)
, one for each channel, converts the digital audio signal from the decoder 46 into an analog audio signal.

A buffer amplifier 62 amplifies the analog signal output from the D/A converter 60.

64 is a low-pass filter, and D/A converter 60
This is a filter circuit for extracting only the necessary low frequency components from the output from the

66 is also a buffer amplifier, which amplifies the acoustic analog signal that has passed through the low-pass filter 64 to a predetermined level.

A speaker 72 outputs the signal amplified by the buffer amplifier 66 as an audible acoustic signal.

Note that headphones or earphones may be provided instead of the speaker 72.

Reference numeral 80 denotes a cassette tape recorder as a recording section, which records the audible audio signal amplified by the buffer amplifier 66 onto a cassette tape (not shown). Although the cassette tape is inserted into the tape recorder 80 by the purchaser, it may also be prepared in advance within the main body of the printing/recording machine.

Next, the musical score printing section connected to the musical score channel output side of the distribution section 40 will be explained.

A decoder 74 decodes the digitized musical score data signal sent from the distribution section 40.

76 is a amplifier which amplifies the digital signal output from the decoder 74.

78 is a printer, which takes in the signal amplified by the buffer amplifier 76 as print data according to a command from the control unit 10, and prints a musical score.

The operation of the musical score printing/recording machine configured as described above will be explained.

The purchaser first enters the title of the sheet music he or she wishes to purchase on Display 4.
4. Use the input key 42 to select a song from the list of song titles displayed. At this point, the purchaser has not inserted the fee, so the charge detection section 45 has not sent the charge input signal to the control section 10.

Therefore, the control unit 10 does not permit the printer 78 to print out, nor does it permit the tape recorder 80 to record. The purchaser selects the song title and clicks
When a "preview" command is sent from 42 to the control section 10, the disk 12 is rotated by the motor 14 controlled by the control section 10, and the optical pickup 16 picks up the disk 12.
The reading of the upper track 18 is started. After confirming that the disc 12 is a CD-1 disc based on the information in the lead-in area 20, the control unit 10 reads the physical address of the musical score data and audio data of the selected song title from the index area 32, and performs optical pickup. 16, both selected pieces of data in the data area 36 are accessed at random, and the musical score data and audio data are read out in this order. The read data is converted into an analog signal and sequentially sent to the digital processing section 38. In the digital processing section 3, the analog signal is converted into a digital signal and sent to the distribution circuit of the distribution section 40. The sequential digital signals sent to the distribution circuit are managed by the microprocessor of the distribution section 40, divided into musical score channels and audio channels, and sent to decoders 46.74 for each channel.

This distribution occurs sequentially, but because it is distributed at the speed of electrons, it appears to humans that the distribution is occurring simultaneously.

On the audio channel side, after a digital signal indicating the content of audio data is decoded by a decoder 46, the digital signal is converted into an analog signal by a D/A converter 60, amplified by a buffer amplifier 62, and then passed through a low-pass filter 64. Only the acoustic signal is taken out and amplified again to a predetermined level by the buffer amplifier 66. Then, the selected music is reproduced from the speaker 72 as an audible acoustic signal. At this time, as described above, the control section 10 commands the tape recorder 80 to stop, so even if a cassette tape is set in the tape recorder 80, no recording is performed.

On the other hand, on the score channel side, after the digital signal indicating the content of the score data is decoded by the decoder 74,
The signal is amplified by a buffer amplifier 76 and sent to a printer 78. However, since no fee has been entered at this point, the control unit 10 instructs the printer 78 to stop, so the sheet music is not printed out. Note that the control unit 10 may cause the distribution unit 40 to stop outputting to the musical score channel side, instead of stopping the printer 78, at the stage before the fee is charged.

When the purchaser confirms the selected music through the speaker 72 and decides to purchase, the purchaser sets the cassette tape in the tape recorder 80, inserts the fee, and inputs the music score purchase and music selection using the input key 42. In this case, when purchasing the musical score of a song that has been previewed, inputting the song selection may be omitted. When the fee is charged, the fee detecting section 45 sends a signal indicating that the fee is being charged to the control section 10, and the control section 10 releases the stoppage of the printer 78 and tape recorder 80. Thereafter, the musical score data and audio data are read out from the disk 12, and the selected music is output from the speaker 72, in the same way as in the above-described procedure. At the same time, the tape recorder 80 is activated to record the music on the cassette tape. On the other hand, musical scores are printed out from the printer that is deactivated on the 7th. All the purchaser has to do is take out the printed sheet music and the recorded cassette tape.

[Second example] A second embodiment will be described with reference to FIG.

Note that the same components as in the first embodiment are given the same reference numerals as in the first embodiment, and explanations thereof will be omitted.

In the second embodiment, the musical score data and audio data digitized by the digital processing unit 38 are sequentially transferred to the first
are simultaneously sent to the second selection section 100 and the second selection section 102.

The first selection unit 100 includes an audio output unit (decoder 46, D
/A converter 60, buffer amplifiers 62, 66, low-pass filters 64, and speakers 72) are connected, and the first selection section 100 extracts only acoustic data from the digital signal sent from the digital processing section 38. and sends it to the audio output section. As a result, an audible acoustic signal is output from the speaker 72, and the audible acoustic signal is recorded by the tape recorder 80, which is a recording section.

On the other hand, the second selection section 102 includes a printing section (decoder 74,
A buffer amplifier 76 and a printer 78) are connected, and the second selection section 102 extracts only the musical score data from the digital signal sent from the digital processing section 38 and sends it to the musical score printing section.

If the control unit 10 makes the printer 78 movable, the musical score is printed out from the printer 78.

The other configurations and functions of the second embodiment are completely the same as those of the first embodiment, so their explanation will be omitted.

Various preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments. Of course, many further modifications can be made without departing from the spirit of the invention, such as stopping the output of the invention.

(Effects of the Invention) When using the musical score printing/recording machine according to the present invention, the music expressed in the musical score to be printed can be heard as an audible sound signal from the acoustic output section, so that the music printed with the musical score can be heard as an audible sound signal. You can know it intuitively. Especially if multiple arrangements of the same song are available, you can definitely choose the one you want. In addition, the recording section can record audible acoustic signals on a cassette tape, etc., so by playing back the cassette tape, you can listen to the performance that matches the score many times, so you can listen to it repeatedly when practicing. This has the effect of increasing the effectiveness of practice.
