DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproduction volume setting device for a recording / reproducing apparatus which records information on a disk-shaped recording medium (disk) and reproduces the recorded information.

[0002]

2. Description of the Related Art Recently, a CD for recording music information such as a music signal on a disk and reproducing the recorded music information.
Recording and playback devices such as (compact disk) players and MD (mini disk) players have become widespread.

In such a CD player or MD player, for example, when a music signal or the like reproduced from one CD by another player is recorded on one MD, the recording level (recording level) is generally determined. I have. In the case where music signals and the like individually reproduced from a plurality of CDs and the like by other players are sequentially recorded on one MD,
Since the reproduction volume level of a music signal or the like reproduced from each CD is different, the recording level at the time of recording on the MD differs depending on the music. Therefore, if this is reproduced as it is, the volume level transmitted from the headphone speaker differs for each song, so that the user has to operate the volume each time to adjust the reproduction volume level to a desired volume.

On the other hand, in order to solve such a problem at the time of reproduction, a recording signal recording level setting method for maintaining a recording level at the time of recording (at the time of recording) (Japanese Patent Laid-Open No. 63-13168). ) Has been proposed (this is referred to as prior art 1). According to the method of the prior art 1, the same signal level as the maximum signal level of a music signal or the like is recorded as a level information signal at the beginning of the music signal or the like and recorded on a disc, and the music signal reproduced from the disc is recorded. When recording the same on another disk, the recording level of a music signal or the like is set according to the peak level of the obtained level information signal.

Thus, music signals and the like individually reproduced from a plurality of discs on which level information signals are recorded are
For example, when recording on another disk, each music signal can be recorded at the recording level corresponding to the peak level of the level information signal, so that the music signal reproduced at each reproduction level is recorded at the same recording level. can do.

Therefore, when a disk on which a music signal or the like is recorded is reproduced in this way, even if the music to be reproduced changes, the volume transmitted from the headphone speaker is almost the same as the volume transmitted during reproduction of the previous music. Since it does not change, the trouble of the user operating the volume each time is eliminated. In addition, a so-called multiple recording technique has been provided in which a music signal or the like is reproduced from a certain recording medium by using such a technique, and at the same time, another music signal or the like is mixed and recorded on another recording medium. (JP-A-6-215534).

[0007]

As described above, according to the prior arts 1 and 2, at the time of recording, a music signal or the like individually reproduced from another disc can be recorded on one disc at the same recording level. Therefore, each music signal or the like is reproduced at the same volume level without the user having to operate the volume each time during reproduction. By the way, the preferable volume level at the time of reproduction depends on the user's own sensibility and differs for each user. Therefore, even if the volume is preferable for a certain user, the volume is too large for another user. In some cases.

In other words, the above-mentioned prior art is designed to automatically record at a fixed level during recording.
Since the volume level at the time of reproduction is not considered at all, the volume level at the time of reproducing a music signal or the like recorded at that recording level is preferably a level for one user, but is preferable for another user. There could be no level. In addition, some users request that the volume at the time of reproduction be set to a desired volume for each recorded song. There is also a preferable volume level depending on the music to be reproduced. However, the above-mentioned prior art has a problem that only the volume level of a music signal or the like at the time of reproduction can be kept constant, and such a request at the time of reproduction cannot be satisfied.

The present invention has been made in order to solve such a problem, and an object of the present invention is to maintain a constant sound volume level during reproduction regardless of a recording level during recording. Another object of the present invention is to provide a playback volume setting device for a recording / playback device, which is capable of automatically setting a volume level for each tune at the time of playback to a volume level suited to the user's preference.

However, FIG. 3 is a flowchart of the recording operation before setting the reproduction volume, and FIG. 4 is a flowchart of the reproduction volume setting operation. Also, FIG.
A state of recording music information such as a music signal in D1 is shown. In an MD player, each piece of music information D1, D2, D
3 have areas T1, T2, T3,... Called TOC (Table Of Contents) for recording data information of the music. Therefore, in the present embodiment, it is assumed that volume level data described later is recorded in the head areas T1, T2, T3,... Called this TOC.

First, the operation of recording music information on the MD1 will be described with reference to the flowchart shown in FIG.
The user first connects an external output terminal (not shown) of another player to the external input terminal 11 of the MD player.
Then, by operating a recording button (not shown) provided on the key input unit 14, the MD player is set to the recording mode (step S1), and another player is set to the reproduction mode.

Thus, a music signal or the like reproduced from a CD, MD, or the like by another player is input to the external input terminal 11.
Is input to the data processing unit 12, where data processing is performed as necessary, and the data is supplied to the pickup 3,
For example, the music information D1 is recorded on the track 21 (step S2). In this case, as a recording level (recording level) of the music information D1 to the MD1, a music signal or the like input from the external input terminal 11 is recorded at the same level.

Similarly, a music signal or the like reproduced from another CD or MD is transmitted from the external input terminal 11 to the data processing unit 1.
2, the data is processed as needed, and is given to the pickup 3 and recorded as music information D2 on, for example, the track 22 of the MD1 (step S3).
To step S2). Also in this case, the MD of the music information D2
The recording level (recording level) to the external input terminal 11
, Etc., is recorded at the same level. In this way, each track 21, 22, 22 of MD1
23,... Are sequentially recorded. When all pieces of music information are recorded (No in step S3), the recording operation ends.

Next, a reproduction volume setting operation for recording volume level data on the MD 1 on which the music information is recorded in this manner will be described with reference to a flowchart shown in FIG. The user reproduces the music information recorded in this way. That is, by operating a play button (not shown) provided on the key input unit 14, the MD player is set to the play mode (step S11). Thereby, for example, a music signal of the music information D1 of the track 21 is reproduced from the MD1 by the pickup 3, and is temporarily stored in the memory unit 4 under the control of the system controller 8. The music signals and the like stored in the memory unit 4 are sequentially read out under the control of the system controller 8, converted into analog music signals and the like by the D / A conversion unit 5, and output to the headphone speaker 7 via the volume control 6. Sent from.

At this time, the user manually operates the volume control 6 while listening to the sound (music or the like) transmitted from the headphone speaker 7 to adjust the desired volume (step S12). When the desired volume is reached, the volume registration button 14a is operated.

When the system controller 8 receives the operation signal of the volume registration button 14a from the key input unit 14 (step S13: Yes), the pickup 3
Is temporarily switched from the reproduction mode to the recording mode (step S14), and the data of the volume level adjusted by the volume control 6 at that time is supplied to the pickup 3 via the data processing unit 12. Then, by the pickup 3, the head portion of the track 21, that is, the head area (TOC) T1 of the recorded music information D1
At step S1.
5). For example, when the position of the volume control 6 when the volume control button 14a is operated is “level 4”,
In the head area T1 of the music information D1, data indicating "level 4" is recorded as a control value of the volume control 6.

At this time, the system controller 8
Controls the notification unit 13 to transmit a confirmation sound (electronic sound) such as “beep, buzz” from the headphone speaker 7 to inform the user that the volume level data has been recorded in the head area T1. I have. This confirmation sound is superimposed on the music being played back and output, but is output immediately after the user operates the volume registration button 14a, so that the user can listen to the electronic sound without discomfort. However, instead of providing such a notification unit 13,
Alternatively, the fact that the volume level data has been recorded in the head area T1 may be displayed on the display unit 15 together with the notification of the notification unit 13.

After recording the volume level data in this manner, the system controller 8 sets the pickup 3 to the reproduction mode again and continues to reproduce the music information D1 (step S16). In this case, the pickup 3 temporarily stops the reproduction mode, but a music signal or the like for about 2 to 3 seconds is stored in the memory unit 4 and is reproduced with a delay of about 2 to 3 seconds ( Therefore, if the volume level data is recorded during that time and the mode is shifted to the reproduction mode again, the music and the like transmitted from the headphone speaker 7 will not be interrupted.

In this way, the user can select each track 2
Song information D2, D3,.
.. Is executed, the head area T2, T3,... Of each piece of music information D2, D3. The desired volume level data is recorded.
In the example shown in FIG. 2, "level 5" is recorded as volume level data in the head area T2 of the song information D2, and the song information D3
"Level 3" as volume level data in the head area T3 of
Is recorded, and “level 6” is recorded as volume level data in the head area T4 of the music information D4.

Next, the operation when reproducing the MD1 on which the volume level data is recorded as described above will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. That is,
When the user operates the play button (not shown) provided on the key input unit 14 to play the MD1 from, for example, the first track 21, first, data information including the volume level data of the head area T1 of the music information D1 is picked up by the pickup 3. It is reproduced and read by the system controller 8 (step S21). The system controller 8 controls the volume control 6 based on the volume level data included in the data information (step S22). That is,
Since the volume level data at this time indicates “level 4”, the system controller 8 sets the volume level 6
At the position where the volume is “level 4” (that is, the display unit 1
Adjust the volume to the position where the number displayed in 5 is “4”).

Thereafter, the music information (music signal, etc.) D1 reproduced from the MD1 by the pickup 3 is temporarily stored in the memory section 4 under the control of the system controller 8, and is sequentially read out at an appropriate timing. , Are converted into analog music signals and the like by a D / A converter 5, adjusted to a “level 4” volume by a volume control 6, and transmitted from a headphone speaker 7. This allows the user to listen to the song (music or the like) at a desired volume without operating the volume control 6 by himself.

Next, when the reproduction of the first music information D1 is completed and the reproduction of the next music information D2 is started (step S2).
3, if the result of step S24 is Yes), the music information D2
The data information including the volume level data of the head area T2 is reproduced by the pickup 3 and read by the system controller 8 (step S21). The system controller 8 controls the volume control 6 based on the volume level data included in the data information (step S22). That is, since the volume level data at this time indicates “level 5”, the system controller 8 sets the volume volume 6 to the position where the volume becomes “level 5” (that is, the number displayed on the display unit 15 is “level 5”). 5)).

Thereafter, the music information (music signal, etc.) D2 reproduced from the MD 1 by the pickup 3 is temporarily stored in the memory section 4 under the control of the system controller 8, and is sequentially read out at an appropriate timing. , Are converted into analog music signals and the like by the D / A converter 5, adjusted to the volume of “level 5” by the volume control 6, and transmitted from the headphone speaker 7. This allows the user to listen to the song (music or the like) at a desired volume without operating the volume control 6 by himself.

In this way, each time any piece of music information is reproduced (Yes in step S24 through step S23)
System controller 8) reads the volume level data recorded in the head area, and based on the volume level data, the volume controller 6
Is adjusted, the user can listen to songs (music and the like) reproduced one after another at a desired volume without operating the volume control 6 at all.

Next, the operation when the level change button 14b and the change registration button 14c are operated will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. For example, M
When the user gets on a crowded train or the like while listening to music by the D player or the like, the user normally operates the volume volume 6 manually to suppress the volume so as to prevent the sound from leaking and disturbing others. Things. At this time, if the operation of the volume control is mistaken, the sound suddenly becomes large and resonates with the ear, and conversely, the sound suddenly becomes small and becomes difficult to hear. That is, the operation of manually operating the volume control 6 to lower the volume to an appropriate level is not always a simple operation. Therefore, in the present invention, in addition to the above basic configuration, a level change button 14b and a change registration button 14c are provided so as to appropriately cope with such a situation.

First, the operation when only the level change button 14b is operated will be described. For example, while the music information D1 is being reproduced at the volume of “level 4” (step S3
1) When the user operates the level change button 14b (in the case of Yes in step S33 via step S32), the system controller 8 changes the volume of the music information D1 from "level 4" to, for example, 2 based on the operation signal. Set the volume control 6 so that the level becomes lower “level 2”.
Is automatically adjusted (step S34). As a result, the volume of the music information D1 is thereafter reproduced at "level 2".

Thereafter, when the reproduction of the music information D1 is ended, and then the reproduction of the music information D2 is started (step S35,
In the case of “Yes” in step S37 via S36), the system controller 8 reproduces the music information D2 at the volume of “level 5” in accordance with the volume level data recorded in the head area T2 as described above. (Step S31). Therefore, when the user operates the level change button 14b again (in the case of Yes in step S33 via step S32), the system controller 8
Is based on this operation signal, so that the volume of the music information D2 becomes “level 3”, which is two levels lower than “level 5”.
The volume control 6 is automatically adjusted (step S34).

As described above, the operation of the level change button 14b is effective only for the music information currently reproduced, and does not affect the reproduction of the next music information. In the above description of the operation, the level change button 14
The description has been given of the case where the volume level is lowered by a predetermined level (2 levels in the above example) by operating b. However, it is set that the volume level is raised by a predetermined level by operating the level change button 14b. Is also possible.

Next, the operation when both the level change button 14b and the change registration button 14c are operated will be described. Here, however, a case where the volume level is lowered by a predetermined level (two levels) by operating the level change button 14b will be described. For example, song information D1
During playback at the volume of “level 4” (step S31),
When the user operates the level change button 14b (Yes in step S33 after step S32), the system controller 8 first sets the volume of the music information D1 to "level 4" based on the operation signal of the level change button 14b.
Then, the volume control 6 is automatically adjusted so that the level becomes, for example, "level 2" lower by two levels (step S34). As a result, the volume of the music information D1 is thereafter reproduced at "level 2".

After the level change button 14b is operated, the system controller 8 operates the change registration button 14
c is operated (Step S3 via Step S35)
6 in the case of “Yes”), the MD1
Are updated to data in which the volume level data recorded in the head areas T1, T2, T3,... Of all pieces of music information D1, D2, D3,. (Step S38). That is,
The volume level data recorded in the head area T1 is rewritten from "level 4" to "level 2", and the volume level data recorded in the head area T2 is rewritten from "level 5" to "level 3". The volume level data recorded in T3 is rewritten from “level 3” to “level 1”, and the volume level data recorded in the head area T4 is rewritten from “level 6” to “level 4”. Thereby, even if the level change button 14b is not operated each time the music information to be reproduced is changed, all the music information is reproduced with the volume lowered by a predetermined level (that is, two levels in the present embodiment). Will be.

In the reproduction volume setting operation in the above embodiment, the music information is recorded on the MD 1 and, at the time of the reproduction,
Although the volume level of each piece of music information is set and recorded in the head area, the data of the volume level of the piece of music information may be simultaneously recorded in the head area when the music information is recorded in the MD1. Good.

In this case, it is necessary to simultaneously record and reproduce the music information. Therefore, in the system configuration shown in FIG. 1, the data is input from the external input terminal 11 between the data processing unit 12 and the pickup 3. It is necessary to provide a memory unit for temporarily storing music signals and the like. Performing recording and reproduction simultaneously in an MD player or the like is a well-known technique in the related art, and a detailed description of the operation is omitted here.

The recording operation of the volume level data in this case may be the same as the reproduction volume setting operation described above, but the operation of the volume registration button 14a by the user is unnecessary, and
It can be fully automated. Here, a brief description will be given of a reproduction volume setting operation in the case of fully automatic operation.

That is, the system controller 8 simultaneously performs control for recording the music information input from the external input terminal 11 on the MD 1 and control for reproducing the recorded music information (accurately, alternately, alternately). Is going. For this reason, a playback sound of the music information being recorded is transmitted from the headphone speaker 7. Therefore, the user manually operates the volume control 6 while listening to the reproduced sound,
Adjust to the desired volume. The system controller 8 reads the volume level data of the volume volume 6 that is manually adjusted, and when the recording of one piece of music information ends, for example, detects the end of recording of the piece of music information by measuring the length of silence time. Then, the read volume level data is recorded in the head area of the music information. This allows the user to
Even when the volume registration button 14a is not operated, the volume level data is automatically recorded in the head area only by manually operating the volume volume 6 when recording music information and adjusting the volume to a desired volume. Will be done.
