First, when recording or reproducing information on or from the optical disc 1 not stored in the disc storage section 33, the disc tray 11 is driven by the tray drive motor 41 to move the disc tray 11 as shown in FIGS. As described above, the state is protruded outside the device case 32. in this case,
The recording / reproducing unit 35 in the device case 32 is rotated so that the turntable 37 is in a horizontal state.

When the disc tray 11 projects from the apparatus case 32, the optical disc 1 on which information is recorded or reproduced by the user is placed on the disc mounting portion 11c of the sub-tray 11b of the disc tray 11.
Is set to When the user instructs the recording or reproduction of the optical disk 11 by the user, the disk drive 11 drives the disk drive 11 to drive the disk tray 11.
It is slid into the device case 32.

At this time, the tray main body 11a and the sub-tray 11b of the disc tray 11
1d and 11e are integrally engaged with the front tray driving gear 39, and the tray main body 11a and the sub-tray 11b are integrally slid into the apparatus case 32. Then, as shown in FIG.
When the apparatus 1a and the sub-tray 11b are housed in the apparatus case 32, as shown in FIG.
Only the rack 11e of 1b meshes with the rear tray drive gear 40, and the sub-tray 11b slides on the tray main body 11a toward the center of the disk storage unit 33,
It is located on a horizontal recording / reproducing unit 35 provided at the center of the disk storage unit 33.

When the recording / reproducing unit 35 is in a horizontal state, as shown in FIG. 17, the guide main body 73a of the disc guide 73 provided on the rotating block 53
For example, the guide rail 73 b is rotated upward by 25 degrees in contact with the boss 78 provided on the inner peripheral wall 57.

It is necessary to form an interval d3 between the two, but by rotating the guide rail 73b, the sub-tray 1
Since the space d1 is formed between the device 1b and the space 1b, the space d3 becomes unnecessary. Therefore, the height of the entire apparatus can be reduced by a length corresponding to the space d3.

When the sub-tray 11b is slid onto the recording / reproducing unit 35, the recording / reproducing unit 35
Is located near the turntable 49 which is the innermost part of the scanning movement range. Thus, the optical pickup 36 has no possibility of interfering with the sliding sub-tray 11b.

When the sub-tray 11b is positioned on the recording / reproducing unit 35, the sub-tray 11b
The optical disk 1 mounted on the disk mounting portion 11c of
The recording / reproducing unit 35 held horizontally by the rotating block 53 is opposed to the recording / reproducing unit 35 via the space of the sub-tray 11b.

In such a state, the unit base 35a of the recording / reproducing unit 35 is moved by the elevating mechanism.
The optical disk 1 is raised by 8.6 mm with respect to the sub-tray 11b, and is held by the turntable 37 on the sub-tray 11b. Further, when the unit base 35a is raised, the magnet 50 of the clamper 49 disposed above the turntable 37 is turned on.
Is sucked. Thus, the optical disc 1 is held between the clamper 49 and the turntable 37.

When the optical disc 1 is held between the clamper 49 and the turntable 37, the rear tray drive gear 40 is rotated in the reverse direction, and the sub-tray 11b is moved approximately 100 mm from the center of the disc storage section 33 toward the tray main body 11a. Slide across.

In such a state, the recording or reproducing operation of the information on the optical disk 1 is started, the turntable 37 is rotated by the motor 37a, and the optical pickup 36 is moved in the horizontal direction along the diameter direction of the optical disk 1. Will be slid. Thereby, recording or reproduction of information is performed on the optical disc 1.

When the recording or reproduction of information on the optical disk 1 is completed, the above-described operation is repeated in the reverse order, so that the optical disk 1 is placed on the disk tray 11 and Are projected outside the device case 32. Then, after that, the disc tray 11 is
The optical disk 11 is taken out from.

The optical disc 1 placed on the disc tray 11 is held horizontally on the turntable 37, after recording or reproduction of information is completed, or after recording or reproduction of information. Without doing
It can also be stored in a predetermined slit 34 in the disk storage section 33.

In this case, the user is instructed to store the optical disc 1 carried into the apparatus case 32 from the disc tray 11 in the slit 34 of the disc storage section 33, and the user inputs information on the optical disc 1 Is registered in the control unit of the disk recording / reproducing apparatus. The control unit selects the slit 34 in the disk storage unit 33 where the optical disk 1 is not supported, and stores the number of the slit 34 and the information of the registered optical disk 1 as a set.

When the control section designates the slit 34 of the disc storage section 33 for storing the optical disc 1, the disc storage section 33 is positioned so that the slit 34 is positioned in the direction indicated by the arrow E in FIG. Is rotated, and the designated slit 34 of the disk storage portion 33 is set at the position indicated by the arrow E in FIG. 1 and faces the slit portion provided on the inner peripheral wall portion 57.

The recording / reproducing unit 35 rotates from a horizontal state to a vertical state. In this case, the sub tray 11
b slides toward the tray body 11a for about 100 mm from the upper position of the recording / reproducing unit 35, which has been in the horizontal state, so that the rotating block 53 moves from the horizontal state to the vertical state. When rotating, there is no possibility of interference with the sub-tray 11b.

When the rotation block 53 rotates from the horizontal state to the vertical state, the optical disc 1 sandwiched between the turntable 37 and the clamper 49 of the recording / reproducing unit 35 also rotates from the horizontal state to the vertical state. . The optical disc 1 is configured such that the rotating block 53 is
Is rotated about a horizontal axis centered at an angle of 45 degrees with respect to the sliding direction of the rotating block 5.
3 is vertical along the axis which is the center of rotation. Therefore, the optical disk 1 in the vertical state is inclined at an angle of 45 degrees in a horizontal plane with respect to the sliding direction of the disk tray 11.

In this case, the pair of disk holding members 65b of the disk transfer mechanism 65 are located at the center of the disk storage portion 33 so as to fit over the optical disk 1 which is in a vertical state, as shown in FIG. It is slid so as to be located above the provided recording / reproducing unit 35.

In such a state, the unit base 35a of the recording / reproducing unit 35 is moved in the direction opposite to the operation for holding the disk 1 by the lifting mechanism, that is, in the direction in which the turntable 37 is separated from the clamper 49. Activated, turntable 37 and clamper 49
Is released from holding the optical disk 1. This allows
The lower part of the optical disk 1 in the vertical state is the disk guide 73.
Is supported by the guide rail portion 73b. In this case, the upper part of the optical disk 1 in the vertical state is located between the pair of disk holding members 65b of the disk transfer mechanism 65.

Thereafter, the disk transfer mechanism 65 is driven, and the pair of disk holding members 65b are moved to the transfer main body 65.
The slider is integrally slid upward along the line a. Thus, the optical disk 1 in the vertical state is moved toward the disk storage section 33 by the disk holding member 65b. The lower portion of the optical disc 1 is supported by a guide rail 73b, and the optical disc 1 moved by the disc holding member 65 rolls on the guide rail 73b. In this manner, the optical disc 1 is transported along a direction inclined by 45 ° with respect to the sliding direction of the disc tray 11.

In this case, the slit 34 of the disk storage unit 33 designated by the control unit is set at the position shown by the arrow E in FIG. 1 and is in a state corresponding to the slit provided on the inner peripheral wall 57. The optical disc 1 conveyed by the disc holding member 65 of the disc transfer mechanism 73
Is transferred to a predetermined slit 34 of the disk storage 33 through a slit provided in the inner peripheral wall 57. Thus, the optical disc 1 is stored in the slit 34.

In this way, the optical disk 1 placed on the disk tray 11 by the user is stored in the slit 34 of the disk storage section 33. In this case, the control unit stores the information of the optical disc 1 stored in the slit 34 together with the number of the slit 34.

When the optical disk 1 is mounted on the optical disk 1, the control unit specifies the slit 34 in which the optical disk 1 is to be stored by simply registering information on the optical disk 1 to be mounted. The information of the optical disk 1 to be stored is stored in the control unit as a set. As a result, the control unit can accurately manage the stored optical disc 1.

In the disk recording / reproducing apparatus of the present embodiment, information can be recorded or reproduced with respect to each disk 1 stored in each slit 34 of the disk storage section 33.

In this case, when the user specifies information on the optical disc 1 to be recorded or reproduced to the control unit,
A pair of disk holding members 65b of the disk transfer mechanism 65
Is slid upwardly of the disk storage section 33, and
The rotating block 53 is rotated so that the recording / reproducing unit 35 is in a vertical state. By the rotation of the rotation block 53, the guide main body 73a of the disk guide 73 becomes horizontal with respect to the slit provided in the inner peripheral wall 57 along the radial direction.

The control unit designates the number of the slit 34 of the disk storage unit 33 in which the optical disk 1 is stored, based on the information on the optical disk 1 instructed, and the slit 34 is moved by the arrow E in FIG. So that the position shown by
The disk storage 33 is rotated. Then, the designated slit 34 is brought into a state of facing the slit portion provided on the inner peripheral wall portion 57.

In such a state, the disk transfer mechanism 65 is driven to drive the pair of disk holding members 65b.
Is integrally slid along the transfer main body 65a from above the disk storage 33 to above the recording / reproducing unit 35. Thus, the optical disc 1 held vertically on the predetermined slit 34 of the disc storage section 33 is transported toward the center of the disc storage section 33 by the disc holding member 65b. Optical disc 1 conveyed by disc holding member 65b
Is transferred to the guide rail portion 73b of the disk guide 73 through a slit portion provided in the inner peripheral wall portion 57, and rolls on the guide rail portion 73b. In this manner, the optical disk 1 is transported along a direction inclined by 45 ° in a horizontal plane with respect to the sliding direction of the disk tray 11.

When the optical disc 1 is transported by the disc holding member 65b to a position between the turntable 37 and the clamper 49 in the vertical state in the recording and reproducing unit 35, the turntable 37 is moved up and down by the lifting mechanism of the recording and reproducing unit 35. The optical disk 1 is moved so as to approach the clamper 49 so that the turntable 37 and the clamper 4 are moved.
9 is held.

Thereafter, the rotation block 53 is rotated from the vertical state to the horizontal state, and the recording / reproducing unit 35 is rotated from the vertical state to the horizontal state. As a result, as shown in FIG. 17, the guide main body 73a of the disc guide 73 provided on the rotating block 53 comes into contact with the boss 78 provided on the inner peripheral wall 57 and rotates, so that the guide rail portion is rotated. 73b

In this state, as described above, the turntable 37 is rotated, and information is recorded or reproduced on the optical disc 1 held by the turntable 37 and the clamper 49 by the optical pickup 36. Will be

After that, when recording or reproducing information on another optical disk 1 stored in the disk storage section 33 continuously, the optical disk 1 held by the recording / reproducing unit 35 is As described above, after being stored in the predetermined slit 34 of the disk storage unit 33, the designated new optical disk 1 is transported to the recording / reproducing unit 35 in the same manner as described above, and the recording / reproducing unit 35
Is rotated from a vertical state to a horizontal state, and then information is recorded or reproduced with respect to the optical unit 1.

Further, when the optical disc 1 is carried out of the apparatus case 32 after the recording or reproduction of information on the optical disc 1 stored in the disc storage section 33 is completed, the recording / reproducing unit is carried out in the same manner as described above. The optical disk 1 held at 35 is placed on the disk tray 11 and is carried out of the apparatus case 32 by sliding the disk tray 11.

Similarly, when the optical disc 1 stored in the slit 34 of the disc storage section 33 is carried out of the apparatus case 32, the optical disc 1 is once held by the recording / reproducing unit 35 and then recorded. The reproduction unit 35 is set in a horizontal state, and is carried out of the apparatus case 32 by the disc tray 11 without recording or reproducing information on or from the optical disc 1.

In the disk recording / reproducing apparatus of this embodiment,
As described above, the recording / reproducing unit 35 that can rotate between the horizontal state and the vertical state is provided at the center of the rotatable annular disk storage portion 33, and the recording / reproducing unit is provided from outside the device case 32. The disc tray 11 is provided with access to the slit 35 of the disc storage unit 33 from outside the device case 32 using the disc tray 11 and the recording / reproducing unit 35. 1 can be stored.

For this reason, the user needs the disk storage unit 3
3, the optical disc 1 is directly inserted into the slits 34 at narrow intervals.
There is no need to store the optical disk 1, and it is not necessary to directly take out the optical disk 1 from the narrowly spaced slits of the disk storage unit 33. For this purpose, the optical disc 1 is manually inserted into each slit 34 of the disc storage unit 33 by a user.
Since there is no need to consider the handling of
The interval of 4 can be set narrow so that the optical disk 1 is mechanically loaded and unloaded. As a result, the number of stored optical disks 1 in the disk storage unit 33 can be increased.

When recording or reproducing information on or from the optical disk 1 that is not stored in the disk storage unit 33, the optical disk 1 does not need to be set in the disk storage unit 33. As described above, the optical disk 1 may be placed on the disk tray 11, and the operability is excellent.

Further, using the disc tray 11,
Since the optical disk 1 can be loaded and unloaded to and from the disk storage unit 33, the user only needs to register information on the optical disk 1 to be loaded and unloaded,
The control unit can accurately manage information on the slit 34 in which each optical disc 1 is stored.

The opening 72 is opened by the opening / closing door 71 provided in the apparatus case 32 for the disk storage section 33, so that the user can directly load and unload the optical disk 1. In this case, , The control unit detects that the opening and closing door 71 is opened,
The storage state of the optical disc 1 in each slit 34 stored in the control unit is reset.

In the disk recording / reproducing apparatus of the present embodiment, the recording / reproducing unit 35 which holds and rotates the optical disk 1 is rotated from the horizontal state to the vertical state. Thus, the optical disc 1 can be rotated from the horizontal state to the vertical state. Therefore, when the optical disc 1 is transported between the disc tray 11 on which the optical disc 1 is placed in a horizontal state and the disc storage section 33 in which the optical disc 1 is supported in a vertical state, the recording / reproducing unit 35 is used. Can be. As a result, a mechanism for transporting the optical disk 1 between the disk tray 11 and the disk storage section 33 is simplified, reliability is improved, and the entire apparatus is downsized.

In addition, the rotation center line when the recording / reproducing unit 35 is rotated between the horizontal state and the vertical state is approximately 45 degrees in the horizontal plane with respect to the sliding direction of the disk tray 11 slid horizontally. Angled in degrees. Thus, when the recording / reproducing unit 35 is rotated vertically, the optical disc 1 held by the recording / reproducing unit 35 is inclined at an angle of about 45 degrees in a horizontal plane with respect to the sliding direction of the disc tray 11. The state is vertical. The optical disk 1 is slid in the horizontal direction along the inclination direction, and the sliding direction is the diagonal direction of the device case 32 having a rectangular parallelepiped shape. A mechanism or the like for sliding the optical disc 1 can be arranged using the space formed at each corner in the rectangular parallelepiped device case 32 for storing the optical disk 1.

As described above, by effectively utilizing the space at the corner of the device case 32,
The whole device can be further miniaturized.

The scanning direction of the optical pickup 36 mounted on the recording / reproducing unit 35 is
When the disk tray 5 is in a horizontal state, as shown by an arrow D in FIG. 6, the disk tray 11 is in a horizontal direction parallel to the central axis of rotation of the recording / reproducing unit 35. Is inclined at approximately 45 degrees with respect to the sliding direction of. As a result, the recording / reproducing unit 3
Even if 5 rotates 90 degrees around the rotation center line and becomes vertical, the scanning direction of the optical pickup 36 is a horizontal direction parallel to the center axis of rotation of the recording / reproducing unit 35. . Thereby, the recording / reproducing unit 3
Although 5 rotates over 90 degrees, the rotation range can be reduced, and the device case 32 can be reduced in size.

For example, when the recording / reproducing unit 35 is in a horizontal state, when the recording / reproducing unit 35 is rotated in a horizontal state about a rotation center axis inclined at an angle of approximately 45 degrees in a horizontal plane with respect to the sliding direction of the disc tray 11, When the scanning direction of the pickup 36 is set to be parallel to the sliding direction of the disc tray 11, when the recording / reproducing unit 35 is rotated from the horizontal state to the vertical state, as shown in FIG. The recording / reproducing unit 35 is in a state of being inclined in a direction perpendicular to the horizontal plane, and a part of the recording / reproducing unit 35 is protruded largely upward. As described above, in order to cover a part of the recording / reproducing unit 35 projecting upward with the device case 32, it is necessary to enlarge the device case 32. However, in the present embodiment, such a problem does not occur. .

In addition, since the scanning direction of the optical pickup 36 is horizontal, the optical pickup 36 does not have the possibility of being affected by gravity when scanning the optical pickup. Can be scanned.

[0113] As shown in FIG.
When the scanning direction is tilted in the direction perpendicular to the horizontal plane, the optical pickup 36 is affected by gravity. In such a case, when vibration is externally applied to the optical pickup 36, a large downward force acts on the optical pickup 36 due to the effect of gravity, and the optical pickup 1 cannot scan stably. There is a possibility that the recorded information cannot be read accurately.

In the disc recording / reproducing apparatus of this embodiment, the recording / reproducing unit 35 is rotated horizontally so that information is recorded or reproduced on / from the optical disc 1 while the held optical disc 11 is kept horizontal. But
With the recording / reproducing unit 35 rotated vertically so that the held optical disk 1 is vertical,
May be recorded or reproduced. In this case, after the optical disk 1 held vertically in the disk storage unit 33 is held by the recording / reproducing unit 35 in the vertical state, information can be recorded or reproduced on the optical disk 1 immediately. Therefore, recording or reproduction of information on the optical disk 1 can be started quickly.

In the disk recording / reproducing apparatus of this embodiment,
Since the opening 72 and the opening / closing door 71 for opening and closing the opening 72 are provided at the front of the device case 32, a large number of optical disks 1 stored in the disk storage 33 can be quickly taken out. In addition, a large number of optical disks 1 can be quickly stored in the disk storage unit 33.

Since the opening 72 and the door 71 are provided above the disk tray 11, even if the disk tray 11 protrudes from the apparatus case 32, the opening 72 is opened by the door 71. When opened, the optical disk 1 can be taken out or stored in the disk storage section 33, which also improves operability.

When the opening 72 is opened and closed by the opening / closing door 71 and the optical disk 1 is taken out or stored in the disk storage section 33, the disk storage section 33 is opened.
It is no longer possible to monitor the storage state of the optical disk 1 in each slit 34, but in this case,
The control unit resets information on the storage state of the optical disc 1 in each slit 34 by a switch that detects the opening and closing of the optical disc 1. After that, the user registers information on the storage state of the optical disc 1 in each slit 34 in the control unit.
