FIG. 10 shows the memory unit 10 shown in FIG.
7 is a diagram showing a specific configuration of FIG. The configuration will be described with reference to FIG.

As shown in the drawing, the information indicating the storage state of the disk includes information on the presence or absence of the disk at the storage position address indicating whether the disk is stored, and the information recorded on the disk stored at the storage position address. (For example, in the case of a DVD-Audio disc, music information such as a track number of a table of contents music recorded in a storage area corresponding to TOC of a compact disc called Simple Audio Manager (hereinafter referred to as a SAMG). ) Indicating whether the disk has been read by the disk reproducing means 100 at least once, and a disk indicating whether the disk stored at the storage position address is a double-sided reproduction disk or a single-sided reproduction disk. Type information and stored in the storage location address Disk storage orientation information, i.e., the case of duplex reproduction disk, A plane reference surface described above,
In the case of a single-sided playback disc, this information indicates which side of the B side is stored and stored, and in the case of a single-sided reproduction disc, which side of the A side or the label side is stored on the reference surface. Although not shown, the memory unit 107 also records surface information of the disk stored at the storage position address and program information of the surface.

The surface information of the disk indicates the A surface and the B surface for a double-sided reproduction disk, and indicates the A surface and the label surface for a single-sided reproduction disk. In the case of a double-sided playback disk, the program information on the surface of the disk is the track number recorded on the A side, the title name corresponding to the track number, the track number recorded on the B side, and the track number. In the case of a single-sided playback disc, it indicates the song number recorded on the A side and the title name corresponding to the song number. Since no information is recorded on the label side, there is no program information.

Next, the meaning of the data ("0", "1") shown in FIG. 10 will be described. “0” in the disk presence information indicates that no disk is stored at the storage position address, and “1” indicates that a disk is stored at the storage position address. "0" in the disk usage information means that the information recorded on the disk stored at the storage position address has not been read by the disk reproducing means 100, and "1" indicates that the information has already been read. It means that it has been read. "0" in the disc type information indicates that the disc stored at the storage position address is a double-sided playback disc, and "1" indicates that the disc is a single-sided playback disc. "0" of the disk storage direction information
Means that the A side of the disk is positioned on the reference plane and is stored in the disk storage unit 23, and "1" indicates that the B side of the disk is positioned on the reference plane in the case of a double-sided playback disk; In the case of a single-sided reproduction disk, it means that the label surface is positioned and stored in the disk storage unit 23.

When the presence / absence information of the disk is "0", no disk is stored in the disk storage section 23, so that the disk use information, the disk type information, and the disk storage direction information may originally exist. Will be no information,
In the present embodiment, it is uniquely set to “0”. This state is referred to as an initial state.

The information indicating the storage state of the disk described above is obtained as follows. The presence / absence information of the disk is transmitted to the disk presence / absence detecting means 102 (sensor 2
6a and 26b).
For example, immediately after the user exchanges a disk and closes the lid 21, the disk storage unit 23 is rotated by the disk storage unit driving means 103 (the drive motor 25, the small gear 25a and the gear unit 23a), and the sensors 26a and 26b To detect the edge of the disc.

The disk use information, disk type information, disk storage direction information, disk surface information, and program information on the surface have the disk presence information of “1”.
Information stored on the disc at the storage location address of
That is, in the case of a double-sided playback disk, information recorded on the A side and the B side, and in the case of a single sided playback disk, information obtained by reading the information recorded on the A side by the disk playback means 100 (the pickup 36 or the like) It is.

Next, the relationship between the storage state of the disk stored in each storage position address of the disk storage unit 23 and the data in the memory unit is recorded in storage position addresses "1" to "6" shown in FIG. A description will be given using the data set.

The storage position address “1” indicates that no disk is stored in the disk storage section 23. In this state, the disk use information, the disk type information, and the disk storage direction information are information that cannot exist.
However, as described above, in the present embodiment, when the disk is not stored in the disk storage section 23, “0” is uniquely set. Therefore, the data at the storage position address "1" has the presence / absence information of the disk "0", the use information of the disk "0", the type information of the disk "0", and the storage direction information of the disk "0". . That is, it is in the initial state.

The storage position address "2" is a state where the disk is stored in the disk storage section 23, but the recorded information has not been read by the disk reproducing means 100 at all. In this state, the disk type information and the disk storage direction information are not obtained, but “0” is set in the disk type information and the disk storage direction information as in the initial state. Therefore, the data of the storage position address "1" has the disk presence / absence information of "1", the disk use information of "0", the disk type information of "0", and the disk storage direction information of "0". .

At the storage position address "3", the double-sided reproduction disk is stored in the disk storage section 23, and the information recorded on the A and B sides of the double-sided reproduction disk has already been read by the disk reproduction means 100. ,Also,
The double-sided reproduction disk is in a state where the surface A is stored with the reference surface positioned at the reference surface. Therefore, the presence / absence information of the disk is “1”, the use information of the disk is “1”, the type information of the disk is “0”, and the storage direction information of the disk is “0”. Although not shown, at this point, the surface information of the A and B surfaces of the double-sided playback disc and the program information of the surface are recorded in the memory unit 107.

At the storage position address "4", the double-sided reproduction disk is stored in the disk storage section 23, and the information recorded on the A and B sides of the double-sided reproduction disk has already been read by the disk reproduction means 100. ,Also,
The double-sided playback disk is in a state where the side B is stored with the reference surface positioned. Therefore, the presence / absence information of the disk is “1”, the use information of the disk is “1”, the type information of the disk is “0”, and the storage direction information of the disk is “1”. Although not shown, at this point, the surface information of the A and B surfaces of the double-sided playback disc and the program information of the surface are recorded in the memory unit 107.

The storage position address "5" indicates that the single-sided reproduction disk is stored in the disk storage section 23, and the information recorded on the A side of the single-sided reproduction disk has already been read by the disk reproduction means 100. The single-sided reproduction disk is in a state where the side A is stored with the reference plane. Therefore, the presence / absence information of the disk is “1”, the use information of the disk is “1”, the type information of the disk is “1”, and the storage direction information of the disk is “0”. Although not shown, at this time, the program information on the A side of the single-sided playback disk is stored in the memory unit 107.
Will be recorded.

The storage position address "6" indicates that the single-sided reproduction disk is stored in the disk storage section 23, and the information recorded on the A side of the single-sided reproduction disk has already been read by the disk reproduction means 100. The single-sided reproduction disk is stored with the label surface positioned at the reference surface. Therefore, the presence / absence information of the disk is “1”, the use information of the disk is “1”, the type information of the disk is “1”, and the storage direction information of the disk is “1”. Although not shown, at this time, the program information on the A side of the single-sided reproduction disk is recorded in the memory unit 107. Next, the operation of the disc changer device of the first embodiment having the above-described configuration will be described with reference to the drawings and the flowchart of FIG. In the description of the operation, the above-described disc will be described as a DVD-Audio disc (hereinafter referred to as a DVD disc) in which a double-sided playback disc and a single-sided playback disc exist.

First, the operation of the user storing or exchanging a DVD disk in the disk storage section 23 and the operation of detecting the presence or absence of a disk in the disk storage section 23 will be described.

When the user opens the lid 21 of the disc changer device shown in FIG. 1, the DVD disc can be exchanged. At this time, the DVD at all the storage location addresses of the memory unit 107 shown in FIG.
The initial state is the information indicating the storage state of the disk or the information indicating the storage state of the DVD disk at the storage position address within the range where the DVD disk can be exchanged through the opening of the lid 21.

The user opens the lid 21 of the disc changer device, takes out the DVD disk to be exchanged from the disk storage unit 23, stores the DVD disk to be reproduced in the disk storage unit 23, and closes the lid 21.

The CPU unit 108 notifies that the lid 21 has been closed.
Is detected, the CPU unit 108 sets the disk storage unit 2
3 is controlled to rotate the disk storage unit driving means 103. When the disk storage unit 23 is rotated, the disk presence / absence detection unit 102 detects the presence or absence of a disk at the storage position address of the disk storage unit 23.

That is, the CPU 108 controls the disk storage unit driving means 103 so that the small gear meshed with the gear 23a formed at the lower part of the inner periphery of the disk storage 23 shown in FIGS. The disk storage section 23 is rotated by the rotation of the drive motor 25 a by the driving force of the drive motor 25. Further, when the disk storage part 23 is rotated, a pair of sensors 26a and 26b provided on the under base 22 with the inner and outer circumferences of the disk storage part 23 shown in FIG. Then, the storage position address where the DVD disk is stored is detected. At this time, the disk presence / absence information of the memory unit 107 is updated from “0” in the initial state to “1”.

The operation for selecting the storage position address and the program information of the DVD disk to be reproduced by the user will be described. In the flowchart of FIG. 11, the user performs an operation of selecting a storage location address and program information of a DVD disc to be reproduced.

As described above, the user operates the jog dial 71 shown in FIG.
The presence / absence information of the disk, the surface information of the disk, and the program information of the surface are displayed on the display unit 70. Further, by referring to the storage position address, the presence / absence information of the disk and the program information, a selection switching button 72 Then, the user operates the selection decision button 73 to select the storage position address and the program information of the DVD disk to be reproduced.

For the storage position address where the presence / absence information of the disk recorded in the memory unit 107 is “0”, the surface information of the disk and the program information of the surface are not displayed on the display unit 70. Further, even if the presence / absence information of the disk is “1”, the storage position address of the use information of the disk is “0” because the disk surface information and the program information of the surface are not recorded in the memory unit 107. On the display unit 70, only the storage position address and the presence / absence information of the disk are displayed. That is, in this case, the user selects only the storage position address with reference to the information on the presence or absence of the disk.

Further, regarding the storage address where the use information of the disk recorded in the memory unit 107 is “1”,
Since the surface information of the disk and the program information of the surface are recorded in the memory unit 107, the display unit 70 displays the storage location address, the presence / absence information of the disk, the surface information of the disk, and the program information of the surface (track number and Title name)
Is displayed. That is, in this case, the user selects both the storage location address and the program information.

If the user erroneously selects a storage position address for which the presence / absence information of the disk is "absent", the display section 70 displays "No disk is stored at the specified address". To end the processing.

Next, the reproducing operation of the DVD disk stored at the storage position address selected by the user will be described. In the flowchart of FIG.
The unit 108 refers to the disk usage information recorded in the memory unit 107 and determines whether the SAMG information recorded on the DVD disk at the storage position address selected by the user has already been read.

First, referring to the flowchart of FIG. 11, a description will be given of a reproducing operation when the CPU unit 108 determines that the SAMG information recorded on the DVD disk at the storage position address selected by the user has already been read. I do. In this case, since the SAMG information recorded on the DVD disk at the storage position address selected by the user has already been read (the use information of the disk recorded in the memory unit 107 is “1”), This means that the selection means 106 selects the program information together with the storage position address.

The CPU unit 108 refers to the disc type information stored in the memory unit 107 and checks whether the DVD disc at the storage position address selected by the user is a double-sided or single-sided reproducing disk. I do. Next, when the type information of the disk is confirmed, the storage direction information of the storage position address is referred to, and whether the DVD disk is stored with the side A positioned at the reference plane, or
Check that the surface (or label surface) is stored with the reference surface positioned.

By confirming the storage direction information of the disk at the storage position address selected by the user, the CPU unit 108 determines whether the A surface or the B surface (or the label surface) of the DVD disk is located on the reference surface and stores the disk. Part 2
3 is selected, and either the first disk transport means 101a or the second disk transport means 101b is selected according to the information recording surface on which the music of the program information selected by the user is recorded.

For example, the DVD disk at the storage position address selected by the user is stored in the disk storage unit 23 with the A side of the DVD disk positioned at the reference plane. The selection of the disk transport means when the information is recorded on the A side is performed as follows.

First, the CPU section 108
With reference to the storage direction information of the disk at the storage position address selected by the user stored in the storage area 23, the side A of the DVD disk at the storage position address selected by the user is positioned in the reference plane and stored in the disk storage section 23. Make sure that Next, the CPU unit 108 controls the D side so that the side A on which the music of the program information selected by the user is recorded faces the pickup 36 of the disk reproducing unit 100.
The first disk transport unit 101a is selected as a unit for transporting the VD disk to the disk reproducing unit 100.

The disk storage position detecting means 104 (slit plate 50 and photocoupler 51) is
08 first disk transport means 101a selected by
Alternatively, the rotation angle position is detected so that the DVD disk at the storage position address selected by the user is brought up to the disk transferable position of the second disk transfer unit 101b, and the disk storage unit driving unit 103 engages with the small disk gear engaged with the gear 23a. When the gear 25a is rotated by the driving force of the drive motor 25, the disk storage unit 2 is rotated to the rotation angle position.
3 is driven to rotate.

The first disk transport means 101a or the second disk transport means 101b transports the DVD disk brought to the position where the disk can be transported to the disk reproducing means 100, and the disk reproducing means 100 transmits the DVD.
The tune of the program information selected by the user recorded on the D disk is reproduced.

That is, the slider 37 as a moving mechanism of the first disk transport means 101a and the second disk transport means.
Is driven, and the DVD disk is pulled out of the slider 37.
It is pulled out by the reset rollers 37a and 37b.
The pulled-out DVD disk is guided by the guide pocket 39a and is moved to the concave portion 39c provided at the center of the bottom of the guide member, that is, in the vicinity of the reproduction position. As described above, the DVD disk on the concave portion 39c is supported so that the center thereof is slightly lower than the center position of the spindle 33 and the clamper 40. Recess 3
When the DVD disk is moved onto 9c, the mechanical holder 2
9 drives and the spindle 33 fits into the center hole 20a of the DVD disk. At the same time, the clamper 40 operates according to the clamp arm 41 via the link mechanism 42, and the DVD
The disc is clamped and lifted slightly upwards. Therefore, the engagement state with the concave portion 39c of the DVD disk is released, and the DVD disk becomes a reproducible state. DVD
When the disc is ready for reproduction, the pickup 36
To play the song of the program information selected by the user.

Next, in the flowchart of FIG.
The U unit 108 stores the D of the storage position address selected by the user.
A reproduction operation when it is determined that the SAMG information recorded on the VD disk has never been read will be described. In this case, the SAMG information recorded on the DVD disk at the storage position address selected by the user is 1
Since it has not been read (the use information of the disk recorded in the memory unit 107 is “0”), the user has selected only the storage position address by the disk selection unit 106 at this time. .

In the memory unit 107, the disk type information and the disk storage direction information of the storage position address selected by the user are set to "0" as in the initial state. The surface information of the disk at the storage position address and the program information of the surface are not recorded.

Therefore, first, the disc use information, disc type information and disc storage direction information recorded in the memory unit 107 at the storage position address selected by the user are updated from the uniquely set “0”. Then, an operation for recording the disk surface information and the program information of the surface in the memory unit 107 is performed. The operation will be described below.

First, the CPU unit 108
Refer to the usage information of the disk at the storage position address selected by the user recorded in. At this time, since the SAMG information recorded on the DVD disk at the selected storage position address has not been read at all, that is, the disk usage information recorded in the memory unit 107 is “0”, The disc type information and the disc storage direction information are set to “0” as in the initial state.

Next, the CPU section 108 selects the selected DV.
The first disc is used as means for causing the disc reproducing means 100 to read the SAMG information recorded on the information recording surface located on the reference plane of the D disc, and for causing the disc reproducing means 100 to convey the DVD disk at the storage position address. The transport unit 101a is selected.

The disk storage position detecting means 104 detects the rotation angle position so as to bring the DVD disk to the selected disk transportable position of the first disk transport means 101a, and the disk storage part driving means 103 rotates the DVD disk. The disk storage unit 23 is rotationally driven to the angular position.

The first disk transport means 101a selected by the CPU section 108 transports the DVD disk brought to the disk transportable position to the disk reproducing means 100, and the disk reproducing means 100 transmits the DVD disc.
The SAMG information recorded on the information recording surface located on the reference surface of the VD disk is read by the pickup 36. At this time, if the SAMG information recorded on the information recording surface located on the reference surface cannot be read, the selected disk is a single-sided reproduction disk and the disc is stored so that the label surface is positioned on the reference surface. It is confirmed that it is done.

After the disc reproducing means 100 reads the SAMG information, the first disc transport means 101a
The original storage position address of the disk storage unit 23 is returned by following the reverse process of transporting the DVD disk of the selected storage position address to the disk reproducing means 100. When the DVD disk is returned to the original storage position address of the disk storage section 23, the SAMG recorded on the information recording surface located on the opposite side to the reference surface of the DVD disk next.
Performs an operation for reading information.

The disk storage section driving means 103 outputs the DVD returned to the original storage position address of the disk storage section 23.
The disk storage unit 23 is moved to the position where the disk can be carried to the position where the disk can be carried by the second disk carrying means 101b.
Drive 0 degrees.

The second disk transport means 101b transports the DVD disk brought to the disk transportable position to the disk reproducing means 100, and the disk reproducing means 100 is on the opposite side of the transported DVD disk from the reference surface. The SAMG information recorded on the information recording surface is read by the pickup 36. At this time, if the SAMG information recorded on the information recording surface located on the opposite side cannot be read, the selected DVD disk is a single-sided reproduction disk, and the information recording surface is located on the reference surface. It is confirmed that it is stored as follows.

When the reading operation of the SAMG information recorded on the information recording surface located on the side opposite to the reference surface of the DVD disk selected by the disk reproducing means 100 is completed, the memory unit 107 is rewritten, The disk use information, the disk type information and the disk storage direction information recorded in the unit 107 are updated from the uniquely set “0”, and the disk surface information of the storage position address and the program of the surface are updated. Information is recorded in the memory unit 107.

For example, the reading of the SAMG information on the information recording surface located on the side opposite to the reference surface of the DVD disk is completed, the storage state of the DVD disk is a double-sided reproduction disk, and the B surface is positioned on the reference surface. If it is found that the disk is used, the disk usage information at the storage position address of the memory unit 107 is unambiguously “1”, the disk type information is “0”, and the disk storage direction information is “1”. The surface information is updated from “0” that is set in the memory, and the surface information of the disk is recorded on the A surface and the B surface, and the program information recorded on the A surface and the program information recorded on the B surface are stored in the memory. Recorded in the unit 107.

As described above, the disc use information, disc type information and disc storage direction information recorded in the memory unit 107 of the storage position address selected by the user are updated from the uniquely set “0”. Further, the disk section information and program information on the side are stored in the memory section 1.
The operation for recording at 07 is completed.

Next, in the flowchart of FIG.
The CPU unit 108 updates the disk usage information, disk type information, and disk storage direction information recorded in the memory unit 107 from “0” which is uniquely set, and stores the disk position information of the storage position address. After the information and the program information on that surface have been recorded, the information recording surface located on the opposite side to the reference surface from which the disc reproducing means 100 last read SAMG information is either the A surface or the B surface (label surface). ) Is determined. Here, when it is determined that the side A is the side, the disc reproducing means 100 reads the SAMG information and then directly reproduces the first tune on the side A.

[0127] If it is determined that the disc is the B-side or the label side, the second disk transport means 101b follows the reverse process of transporting the DVD disk to the disk reproducing means 100, and returns to the original storage position of the disk storage part 23. Return to address.
The disk storage unit driving means 103 includes the disk storage unit 23
The disk storage unit 23 is rotated by 180 degrees so that the DVD disk returned to the original storage position address is brought to the disk transferable position of the first disk transfer means 101a.

The first disk transport means 101a transports the DVD disk brought to the disk transportable position to the disk reproducing means 100, and the disk reproducing means 100 reproduces the first music on the A side of the transported DVD disk. I do.

In the above description, the information indicating the storage state of the disk recorded in the memory unit 107 is updated from the uniquely set “0”, and the surface information of the disk and the program information of the surface are recorded. First, the CPU unit 108 causes the pickup 36 of the disk reproducing unit 100 to read the SAMG information on the information recording surface located on the reference surface of the selected DVD disk. Has been described.

However, the present invention is not limited to this, and the storage position address of the selected disk in the disk storage unit 23 is determined by the disk transferable position of the first disk transfer means 101a or the disk transferable position of the second disk transfer means 101b. May be determined by the CPU unit 108, and the disk transport unit closer to the disk transportable position may be selected. The operation in that case is as follows.

If the selected storage position address is close to the position at which the second disk transport means 101b can transport the disk, C
When the PU unit 108 determines, the CPU unit 108
The second disk transport unit 101b is selected as a unit for transporting the D disk to the disk playback unit 100, and the selected second disk transport unit 101b transports the DVD disk to the disk playback unit 100.

Therefore, first, the SAMG information on the information recording surface opposite to the reference surface of the DVD disk is read by the pickup 36 of the disk reproducing means 100, and the DVD disk is returned to the original storage position address.

Thereafter, the disk storage section 23 is rotated by 180 degrees to bring the DVD disk to the position where the first disk transport means 101a can transport the disk, and the first disk transport means reproduces the DVD disk into the disk reproducing means 100a.
Then, the SAMG information on the information recording surface located on the reference surface is read by the pickup 36 of the disk reproducing means 100.

When the read operation of the SAMG information on the information recording surface located on the reference surface is completed, the information indicating the storage state of the disk recorded in the memory unit 107 is updated from "0" which is uniquely set, and The surface information of the disk and the program information of the surface are recorded in the memory unit 107.

Next, the CPU unit 108 determines whether or not the information recording surface located on the reference surface from which the disk reproducing means 100 last read the SAMG information is the A surface. After reading the SAMG information, the reproducing means 100 reproduces the first tune on the A side as it is.
At 01b, the DVD disk is transported to the disk reproducing means 100, and the first tune on the A side is reproduced.

As described above, the first disk transport means 101a is not limited to firstly reading the SAMG information on the information recording surface located on the reference surface. It is also possible to select a disk transport means closer to the above, and by doing so, it is possible to reduce the time from the user's selection of the disk to the reproduction.

In the reproducing operation described above, the DV
The SAMG information of the D disk was read and recorded when the reproduction was selected for the first time after being stored in the disk storage unit 23. However, the SAMG information of all the DVD disks is automatically stored after the DVD disk is exchanged. The reading and the memory unit 107 may be rewritten in advance. Hereinafter, the operation of the automatic memory update will be described.

When the user operates the memory update button 74 when the DVD disc is not reproduced, for example, at night, C
The PU unit 108 detects that the button has been operated. Then, the disk storage unit 23 is rotationally driven by the disk storage unit driving unit 103, and the disk presence / absence detection unit 102 detects the presence or absence of a disk stored in the disk storage unit 23.

When the presence / absence of a disk is detected by the disk presence / absence detecting means 102, the presence / absence information of the disk recorded in the memory unit 107 is updated.
