Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an audio reproducing apparatus.

[0002]

2. Description of the Related Art A CD player or MD player has a resume function. When a stop button is operated during reproduction, a reproduction position (reproduction address) at that time is stored in a memory and a stop mode is entered. When the playback button is operated during the stop, the playback position stored when the stop mode is entered is read from the memory, and the playback of the CD or MD is resumed from the read playback position.

[0003] Therefore, when the reproduction button is operated from the stop mode, reproduction of music or the like can be resumed from the position where the stop mode was previously set. That is, the same operability as when using a headphone stereo, cassette deck, or the like is obtained.

[0004]

However, when the reproduction is resumed from the stop mode as described above, when the reproduction is resumed from the position where the previous stop mode was set, the reproduction is almost resumed from the middle of the music in most cases. That's pretty uncomfortable as music.

[0005] For example, if you are listening to a CD or MD when commuting, when you go to work, you start listening to the music you were listening to while you were home while you were coming home the previous day, which is quite uncomfortable from the standpoint of listening to music. It is.

[0006] In addition, stationary CD players and MD players generally have a timer playback function (a function for automatically entering a playback mode when the power is turned on) and a music order playback function (a designated music piece is designated). A function for playing back in the specified order), a repeat playback function (a function for repeatedly playing back a specified song), and the like are provided, but when the timer playback function and the song order playback function are used together, a trouble may occur.

That is, if the time at which the power of the player is turned on and the time at which the player is turned off are set in the timer and the timer reproduction function is set to be valid, for example,
The music reproduced from the player can be set as an alarm. After waking up, the music to be played is
When you go to work, you can automatically turn off the power.

However, in this case, when the timer is turned on, the reproduction is started from the first tune specified by the tune order reproduction function every day, so that the power of the player is turned on by the timer. If the time period is shorter than the total playing time of the song specified by the song order playback function, there are songs that are always played every day and songs that are never played.

In this case, such a trouble can be avoided by enabling the resume function and starting reproduction from the previously stopped position when starting reproduction as described above. However, in that case, most of the time, the reproduction is started from the middle of the music by the resume function, which is also uncomfortable and especially inappropriate for wake-up.

[0010] The present invention is to solve the above problems.

[0011]

Therefore, according to the present invention, digital audio data recorded on a randomly accessible recording medium is reproduced, and
An audio reproducing apparatus that obtains and outputs an analog audio signal from the digital audio data, has a play button, a stop button, and a non-volatile memory, and operates the stop button during reproduction. At this time, the data indicating the track being reproduced is held in the memory, and when the play button is operated next, the data is read from the memory, and the stop button is operated according to the read data. This is an audio reproducing apparatus in which reproduction is started from the head position of the track being reproduced. Therefore, when the reproduction is resumed from the stop mode, the reproduction is started from the head position of the track including the reproduction position regardless of the reproduction position at the time of the previous stop mode.

[0012]

FIG. 1 shows an embodiment in which the present invention is applied to a portable type MD player. Reference numeral 10 denotes an MD. The MD 10 is configured by storing a magneto-optical disk (or optical disk) 11 in a dedicated cartridge 12.

At the time of reproduction, the disk 11 is rotated by the spindle motor 31, and the rotation is controlled by the servo control circuit 32 so that the linear velocity of the disk 11 becomes constant. Also, disk 1
An optical pickup 21 is disposed on one surface of the cartridge 1 so as to face through a shutter opening of the cartridge 12.
The focus and tracking of the optical pickup 21 are controlled by a servo control circuit 32, and the optical pickup 21
3, the disk 11 can be moved in the radial direction.

Further, a microcomputer 34 is provided for system control. In this case, the microcomputer 34 has a normal mode and a standby mode, and performs a normal operation in the normal mode, but waits for an input by the user with the minimum power consumption in the standby mode. The microcomputer 34 is provided with, for example, a reproduction routine 100 shown in FIG. 2 as a part of a program for managing the operation. Although the details of this routine 100 will be described later, FIG. 2 shows only parts related to the present invention for simplicity.

Operation buttons 35 such as a play button and a stop button are constituted by non-lock type normally open switches and connected to the microcomputer 34, and the microcomputer 34 has a display 36.
The display 36 displays various information related to the reproduction of the disk 11, such as the track number of the music being reproduced and the playing time of the music being reproduced.

Further, the microcomputer 34 includes:
The resume mode switch 37 and a nonvolatile memory, for example, a flash memory 38 are connected. In this case, when the MD player resumes playback from the stop mode, the switch 37 restarts playback in the first mode (hereinafter, referred to as “track resume mode”) or in the second mode (hereinafter, “track resume mode”). This is for the user to set whether to resume the reproduction in the “tape resume mode”. The memory 38 is for resume,
Track number TNO when resuming playback from stop mode
And the address ADR.

At the time of reproduction, the optical pickup 21
, A signal is read from the disk 11, and this signal is supplied to the servo control circuit 32 through the RF amplifier 22 to execute focus servo and tracking servo.

Further, at the time of reproduction, a reproduction signal from the RF amplifier 22 is supplied to a decoder circuit 23 and subjected to EFM demodulation, error correction is performed, and digital audio data is taken out. Through buffer memory 2
5 and read out in order to form continuous digital audio data.

The digital audio data is supplied to a decoder circuit 26 through a memory controller 24.
The digital audio data is supplied to the D / A converter 27, where it is subjected to D / A conversion into original stereo analog audio signals L and R. , R are taken out to the output terminal 28. Therefore, the stereo audio signals L and R are reproduced from the MD 10.

Further, at the time of reproduction, an output signal of the RF amplifier 22 is supplied to a decoder circuit 29 to extract an absolute address signal. The absolute address signal is supplied to a microcomputer 34 through the decoder circuit 23, and the servo control circuit 32 It is used for controlling the reproduction position of the optical pickup 21 in the disk radial direction. In the microcomputer 34, address information in sector units is also extracted from the reproduction signal, and is used for managing the reproduction position of the optical pickup 4.

Then, the routine 100 is executed in the microcomputer 34 as follows.

That is, when the MD 10 is set in the player, the microcomputer 34 shifts from the standby mode to the normal mode, and the processing of the routine 100 starts from step 101. Next, in step 102, the track number "1" of the first track is set. And the first address of the first track, for example, "00 cluster 00 sector" are written in the memory 38 as the track number TNO and the address ADR.

Then, in step 103, the operation of the reproduction button of the operation buttons 35 is awaited. This state is a stop mode. In this stop mode, the microcomputer 34 transits from the normal mode to the standby mode again.

Then, when the play button is pressed, the microcomputer 34 shifts from the standby mode to the normal mode again, and the processing proceeds from step 103 to step 1.
Then, at step 111, the memory 38
, The track number TNO and the address ADR are read, and in this case, TNO = 1 and ADR = 00: 00 are read,
Next, at step 112, the mode indicated by the switch 37 is determined.

When the switch 37 is set to the track resume mode, the processing proceeds to step 1
12 to step 113, in which the reproduction position of the optical pickup 21 is set to step 1
In step 115, the track number TNO is set at the head position of the read track, and then in step 115, reproduction is started from the set position. In this case, TNO = 1
Therefore, the reproduction is started from the head position of the first track.

If the switch 37 is set to the tape resume mode in step 112, the process proceeds from step 112 to step 114,
In step 114, the reproduction position of the optical pickup 21 is set to the address ADR read in step 111, and then reproduction is started from that set position in step 115. In this case, ADR = 00: 00
Since this is the start address of the first track, reproduction is started from the start position of the first track.

Thus, when the MD10 is set in the player and the play button is pressed for the first time, the reproduction is started from the beginning of the first track. The signal processing method for reproducing the audio signals L and R from the disk 11 is as described above.

Then, in step 115, the disk 1
When the reproduction of No. 1 is started, the process proceeds to step 116, in which the track number of the track being reproduced is compared with the track number TNO written in the memory 38 to perform reproduction. It is determined whether or not the current track has advanced to the next track. If the current track has not advanced to the next track, the process proceeds to step 11.
6 to step 118.

In step 118, it is determined whether or not the stop button of the operation buttons 35 has been pressed. If not, the process returns from step 118 to step 116. Therefore, step 115
, The reproduction is continued, and steps 116 and 118 are repeated during the reproduction.

Then, when the track being reproduced advances to the next track by continuing the reproduction, this is determined in step 116, and the process proceeds to step 11
From 6, the process proceeds to step 117. In this step 117, the track number TNO of the memory 38 is incremented by “1”, and thereafter, the process proceeds to step 118.

When the reproduction of the MD 10 is started, the reproduction is continued, and the reproduction position on the disk 11 gradually changes as shown by the solid line PB1 in FIG. During playback, the stop button is monitored and the track number TNO in the memory 38 is updated to the track number of the track being played. This state is a reproduction mode state.

When the stop button is pressed at an arbitrary point in time when an arbitrary track is being reproduced, for example, as shown in FIG. The process proceeds from step 118 to step 121, as determined by step 118. At step 121, the reproduction address Am of the disk 11 reproduced at this time tm is written to the memory 38 as the address ADR.

Next, at step 122, a predetermined control signal is supplied from the microcomputer 34 to the servo control circuit 32 to stop the player, and thereafter, the process returns to step 103 and waits for the operation of the play button. That is, the stop mode is set.

At this time, since the reproduction is stopped, the track number TNO in the memory 38 is not updated, and the track number of the track being reproduced when the stop button is pressed. In FIG. The number remains n.

When the playback button is pressed in the state where the playback mode is changed to the stop mode,
Again, the process proceeds from step 103 to step 111 as described above, and further proceeds to step 112.

When the switch 37 is set to the track resume mode in step 112, the optical pickup 21
Is set to the head position of the track with the track number TNO read in the immediately preceding step 111, and then in step 115, the reproduction is started from the set position.

In this case, the track number T in the memory 38
Since NO is the track number n when the stop mode was previously set in step 121, the solid line P in FIG.
As indicated by B2, the reproduction is started from the head position of the track of the track number n.

Thus, when the play button is pressed when the switch 37 is set to the track resume mode, playback is performed when the previous stop button is pressed, regardless of the playback position when the previous stop button was pressed. The reproduced track is reproduced from the head position. Thereafter, the reproduction is continued, and the above-described processing is repeated each time the stop button or the reproduction button is pressed.

On the other hand, when the switch 37 is set to the tape resume mode in step 112, the reproduction position of the optical pickup 21 is set to the track position indicated by the address ADR read in step 111 in step 114. And then step 1
15 starts reproduction from the set position.

In this case, the address ADR of the memory 38
Is the address Am when the stop mode was previously set in step 121, so that the reproduction is started from the track position of the address Am as shown by the broken line PB3 in FIG.

Thus, when the play button is pressed when the switch 37 is set to the tape resume mode, the reproduction is resumed from the reproduction position at the time when the stop button was previously pressed. After that, the playback continues,
Each time the stop button or the play button is pressed, the above processing is repeated.

As described above, in the above-mentioned MD player, when the resume mode is set to the track resume mode, when the reproduction is resumed from the stop mode, the reproduction is performed when the previous stop button was pressed. Since the reproduced track is reproduced from the head position, the reproduction is always restarted from the beginning of the music, and the discomfort is eliminated.

When the resume mode is set to the tape resume mode, when the reproduction is resumed from the stop mode, the reproduction is resumed from the position where the reproduction was previously performed when the stop button was pressed. Because
If one song is listening to a long classical song or the like, the same song will not be heard from the beginning each time playback is resumed.

FIGS. 4 and 5 show a reproduction routine 20 applicable to a stationary MD player having a timer reproduction function.
This is the case of 0. Note that the MD player in the following description is configured in the same manner as the player in FIG. 1, but when the power is off, the microcomputer 34 is backed up by a built-in battery and stands by in a standby mode.

That is, in the case of the routine 200, when the power switch is turned on, the microcomputer 34
Transitions from the standby mode to the normal mode, and the processing of the routine 200 starts from step 201.
Then, in step 202, the MD10 is given to the player.
It is determined whether or not is set. If not, the process proceeds from step 202 to step 2
In step 203, the process waits for the MD 10 to be set in the player.

When the MD 10 is set in the player, the process proceeds to step 204, where the process proceeds to step 20.
4, the track number “1” of the first track and the start address of the first track, for example, “00 cluster
00 sector "is written in the memory 38 as the track number TNO and the address ADR. Then, the process proceeds to step 205.

In step 202, when the MD 10 is set in the player, the process proceeds from step 202 to step 205.

Therefore, when the power is turned on with the MD 10 not set in the player, the memory 38
The track number TNO and the address ADR are set to the initial values, and when the power is turned on with the MD 10 set, the track number TNO and the address ADR of the memory 38 become the values when the power was last turned off.

In step 205, it is determined whether the timer reproduction function is set to ON (valid) or OFF (invalid).
The process proceeds from step 205 to step 206, in which the operation of the reproduction button of the operation buttons 35 is awaited. This state is a stop mode state.

Then, when the play button is pressed, the process proceeds from step 206 to step 211.

If it is determined in step 205 that the timer reproduction function is ON, the process proceeds from step 205 to step 211.

Therefore, when the power is turned on, if the timer reproduction function is off, if the reproduction button is pressed, the processing proceeds from the stop mode to the end, and if the timer reproduction function is on, the special button operation is performed. The processing proceeds from the stop mode to the next step without performing the operation.

In step 211, the track number TNO and the address ADR are read from the memory 38. In this case, TNO = 1 and ADR = 00: 00 are read. Is determined.

When the switch 37 is set to the track resume mode, the processing proceeds to step 2
12 to step 213, in which the reproduction position of the optical pickup 21 is
In step 215, reproduction is started from the set position at the head position of the track with the read track number TNO. In this case, since TNO = 1, reproduction is started from the head position of the first track.

If the switch 37 is set to the tape resume mode in step 212, the process proceeds from step 212 to step 214,
In step 214, the reproduction position of the optical pickup 21 is determined by the address A read in step 211.
DR is set, and then reproduction is started from the set position in step 215. In this case, ADR = 00: 00, and since this is the start address of the first track, reproduction is started from the start position of the first track.

Thus, when the MD 10 is set on the player and the reproduction is first started, the reproduction is started from the head of the first track. The signal processing method for reproducing the audio signals L and R from the disk 11 is as described above.

Then, in step 215, the disk 1
When the reproduction of No. 1 is started, the process proceeds to step 216. In this step 216, the reproduction is performed by comparing the track number of the track being reproduced with the track number TNO written in the memory 38. It is determined whether the current track has advanced to the next track. If the current track has not advanced to the next track, the process proceeds to step 21.
6 to step 218.

In step 218, it is determined whether the stop button has been pressed. If not, the process proceeds from step 218 to step 219. In step 219, it is determined whether the power has been turned off. If it is determined that it has not been turned off, the process returns from step 219 to step 216.

Therefore, when the reproduction is started in step 215, the reproduction is continued, and steps 216, 118, and 219 are repeated during the reproduction.

When the track being reproduced advances to the next track as the reproduction is continued, this is determined in step 216, and the process proceeds to step 21.
6, the process proceeds to step 217. In this step 217, the track number TNO of the memory 38 is incremented by "1", and thereafter, the process proceeds to step 218.

When the reproduction of the MD 10 is started in this way, the reproduction is continued, and the reproduction position on the disk 11 gradually changes as shown by the solid line PB1 in FIG. During playback, the state of the stop button and the power supply are monitored, and the track number TNO in the memory 38 is updated to the track number of the track being played back. This state is a reproduction mode state.

When a stop button is pressed at an arbitrary point in time when an arbitrary track is being reproduced, for example, as shown in FIG. The process proceeds from step 218 to step 221 in which the track number n of the track being reproduced at time tm and the reproduction address Am of the disk 11 are stored in the memory 38 by the track number TNO and the address. Written as ADR.

Subsequently, in step 222, a predetermined control signal is supplied from the microcomputer 34 to the servo control circuit 32 to stop the player, and thereafter, the process returns to step 206 to wait for the operation of the play button. . That is, the stop mode is set.

At this time, since the reproduction is stopped, the track number TNO in the memory 38 is not updated, and the track number of the track being reproduced when the stop button is pressed, in the case of FIG. The number remains n.

Then, when the playback button is pressed in the state where the playback mode is changed from the playback mode to the stop mode,
Again, the process proceeds from step 206 to step 211 and further to step 212 as described above.

When the switch 37 is set to the track resume mode in step 212, in step 213 the optical pickup 21
Is set to the head position of the track with the track number TNO read out in the immediately preceding step 211, and then the reproduction is started from that set position in step 215.

In this case, the track number T in the memory 38
Since NO is the track number n when the stop mode was previously set in step 221, the solid line P in FIG.
As indicated by B2, the reproduction is started from the head position of the track of the track number n.

Thus, when the play button is pressed when the switch 37 is set to the track resume mode, regardless of the playback position when the previous stop button was pressed, the playback was performed when the previous stop button was pressed. Playback is resumed from the beginning of the track. Thereafter, as described above, the reproduction is continued, and each time the stop button or the reproduction button is pressed, the above-described processing is repeated.

When the switch 37 is set to the tape resume mode in step 212, the reproduction position of the optical pickup 21 is set to the track position indicated by the address ADR read in step 211 in step 214. And then step 2
15 starts reproduction from the set position.

In this case, the address ADR of the memory 38
Is the address Am when the stop mode was previously set in step 221, so that the reproduction is started from the track position of the address Am as shown by the broken line PB3 in FIG.

Thus, when the playback button is pressed while the switch 37 is set to the tape resume mode, the playback is restarted from the playback position at the time when the stop button was previously pressed. Thereafter, as described above, the reproduction is continued, and each time the stop button or the reproduction button is pressed, the above-described processing is repeated.

On the other hand, when the power is turned off during, for example, time tm during reproduction, this is determined in step 219, and the process proceeds from step 219 to step 231. In this step 231, the track of the track being reproduced at time tm Number n and playback address A of disk 11
m stores the track number TNO and the address A in the memory 38.
Written as DR.

Subsequently, in step 232, a predetermined control signal is supplied from the microcomputer 34 to the servo control circuit 32 to stop the player, and then in step 233, the microcomputer 3
4 transitions from the normal mode to the standby mode and waits until the power is turned on. This is the state when the power is turned off after performing the reproduction even once.

When the power is turned on while the power is turned off in this way, the process also starts from step 201 as described above.
Since 0 has been set, the processing proceeds to steps 203 and 2
Skip step 04 and proceed to step 205.

If the timer playback function is set to ON in step 205 or if the playback button is pressed in step 206, the process proceeds to step 211 as described above, and further proceeds to step 212.
Proceed to.

When the switch 37 is set to the track resume mode in step 212, in step 213 the optical pickup 21
Is set to the head position of the track with the track number TNO read out in the immediately preceding step 211, and then the reproduction is started from that set position in step 215.

In this case, the track number T in the memory 38
Since NO is the track number n at the time when the reproduction was stopped last time in step 221, the solid line PB2 in FIG.
As shown by, the reproduction is started from the head position of the track of the track number n.

Thus, when the switch 37 is set to the track resume mode, regardless of the playback position at the time when the previous playback was stopped, the track being played back at the previous stop is played back from the head position. Is done. Thereafter, the reproduction is continued, and the above-described processing is repeated each time the stop button or the reproduction button is pressed, or each time the power is turned on / off.

When the switch 37 is set to the tape resume mode in step 212, the reproduction position of the optical pickup 21 is set to the track position indicated by the address ADR read in step 211 in step 214. And then step 2
15 starts reproduction from the set position.

In this case, the address ADR of the memory 38
Is the address Am at the time when the reproduction was previously stopped in step 221, so that the reproduction is started from the track position of the address Am as shown by the broken line PB3 in FIG.

Thus, when the switch 37 is set to the tape resume mode, the reproduction is resumed from the reproduction position where the previous reproduction was stopped. Thereafter, the reproduction is continued, and the above-described processing is repeated each time the stop button or the reproduction button is pressed, or each time the power is turned on / off.

MD having routine 200 as described above
When the resume mode is set to the track resume mode in the player, when resuming playback from the stop mode, the track that was playing when the previous playback was stopped will be played from the beginning position. Therefore, the reproduction is always restarted from the beginning of the song, and the discomfort is eliminated.

Also, since the track at the time of the previous stop of playback is played back from its head position, when the timer playback function and the music order playback function are used together, the power of the player is turned on by the timer. Even when the period is shorter than the total playing time of the song specified by the song order playback function, there is no occurrence of a song that is never played, and the BGM
Comfortable for wake up.

Further, when the resume mode is set to the tape resume mode, when the reproduction is resumed from the stop mode, the reproduction is resumed from the position where the previous reproduction was stopped. So 1
If you are listening to a long classic song, you will not hear the same song from the beginning each time you resume playback.

In the above description, the MD10 is used as a recording medium for digital audio data. The recording medium may be any medium that can randomly access digital audio data. For example, a semiconductor memory may be used. it can.

FIG. 6 shows a portable player using a semiconductor memory as a recording medium for digital audio data.

That is, reference numeral 40 denotes a recording / reproducing memory cartridge, which is structured such that a nonvolatile memory, for example, a flash memory 41 is housed in a predetermined cartridge 42 and can be attached to and detached from a player. The digital audio data is written in the memory 41 after being compressed according to, for example, the MPEG3 standard. Further, a management area for digital audio data written in the memory 41 is prepared in the memory 41. For example, one piece of music is managed as one track (file).

A memory controller 51 is provided as a control circuit for reading digital audio data from the memory 41, and the microcomputer 34 is connected to the memory controller 51 for system control. In this case, the microcomputer 3
Reference numeral 4 has a normal mode and a standby mode. In the normal mode, normal operation is performed, but in the standby mode, an input by a user is waited for with minimum power consumption. The microcomputer 34 is provided with, for example, a reproduction routine 100 shown in FIG. 2 as a part of a program for managing the operation.

Further, operation buttons 35 such as a reproduction button and a stop button are constituted by a non-lock type normally open switch and connected to the microcomputer 34. When the operation button 35 is operated, the operation button 35 corresponds to the operated button. Commands and data are stored in the microcomputer 5
1 to the memory controller 51
The readout of the digital audio data written in and the readout address thereof are controlled.

A display 36 is also connected to the microcomputer 34. The display 36 displays various information related to the reproduction of the memory 41, such as the playing time of the music being reproduced and the track number of the music being reproduced. . Further, the microcomputer 34 is connected with a resume mode switch 37 and a nonvolatile memory, for example, a flash memory 38.

Then, the memory cartridge 4 is provided to the player.
When 0 is set, and when the play button or the stop button of the operation buttons 35 is pressed, the routine 100 is executed in the microcomputer 34 as described above.

At the time of reproduction, data is read from the memory 41 by the memory controller 51, and the data is transmitted to the decoder circuit 5 through the memory controller 51.
The digital audio data is supplied to the D / A converter 57, and the digital audio data is D / A converted to the original stereo analog audio signals L and R. L, R
Is output to the output terminal 58. Therefore, memory 4
1 means that the stereo audio signals L and R have been reproduced.

In this player, when the resume mode switch 37 is set to the track resume mode, when the reproduction is resumed from the stop mode, the track which was reproduced when the previous stop button was pressed is used. Since the reproduction is started from the head position, the reproduction is always restarted from the beginning of the music, and the discomfort is eliminated.

When the resume mode switch 37 is set to the tape resume mode, when the reproduction is resumed from the stop mode, the reproduction is resumed from the position where the reproduction was performed when the stop button was previously pressed. Therefore, if one song is listening to a long classical song or the like, the user does not listen to the same song from the beginning each time the reproduction is resumed.

FIG. 7 shows the routine 200 of FIGS. 4 and 5.
This is a case where a repeat playback function is added to. However, illustration and description of steps overlapping with the routine 200 of FIGS. 4 and 5 are omitted.

Then, in the routine 200 shown in FIG.
Then, in step 241, it is determined whether or not the reproduction of the last track of the MD 10 has been completed.
If not, the process proceeds from step 241 to step 218. Therefore, steps 216, 217, 241, and 218 are repeated during reproduction.

When the reproduction of the last track of the MD 10 is completed, this is determined in step 241.
The process proceeds from step 241 to step 242. In this step 242, the track number T
NO is set to "1", and thereafter, the process proceeds to step 21.
Return to 3. Therefore, in the case of the routine 200 shown in FIG. 7, all the songs (tracks) are connected in a ring shape, and the songs whose reproduction has been stopped last time can be played back in order, thereby realizing the repeat playback.
