Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a disk driver for recording or reproducing a disk such as a compact disk.

[0002]

2. Description of the Related Art Conventionally, there has been known a disk driver for recording or reproducing a disk such as a compact disk by using a magazine accommodating a plurality of disks.
The magazine used in this disc driver is one in which the inside is divided into multiple stages by partition plates, the disc storage parts for storing one disc each are stacked, and a disc insertion opening for inserting a disc is provided on one side surface. is there. And
The disk driver is provided with a disk storage section for detachably mounting the magazine in the housing and a recording / reproducing section for recording or reproducing the disk. And
In such a disc driver, there are a type in which a recording / reproducing unit having a turntable for mounting a disc and rotating is fixed to the lower part of the housing, and a type in which the recording / reproducing unit itself moves up and down to a desired disc position. There are two types.

In the former case, it is necessary to vertically lower the disk pulled out from the magazine to the lower part of the housing where recording or reproduction of the disk is performed. For this reason, the entire disc must be completely withdrawn from the magazine. On the other hand, in the latter, recording or reproducing of the disc is performed at the position of each disc. For this reason, it is sufficient for the disc to be pulled out horizontally from the magazine, and a large vertical descent is unnecessary. Therefore, in the latter case, the size of the disk driver is reduced by recording or reproducing the disk while leaving a part of the disk in the magazine. The present invention is applied to this type of disk driver.

In the recording / reproducing section of this type of disc driver, a turntable is provided above the turntable and a clamper for clamping the disc on the turntable, and a magazine is recorded on both sides of the disc. A pair of disc rollers for transporting between the reproducing units are provided. In this type of apparatus, a desired disc pulled out from a magazine is conveyed onto a turntable by a disc roller, fixed on the turntable by a clamper, and then recorded or reproduced.

[0005]

However, the conventional device of this type has the following problems. That is, in general, the center of the turntable is projected upward, but in the conventional device, the turntable is fixed on the recording / reproducing unit and cannot move up and down on the recording / reproducing unit itself. . Therefore, in order to prevent the disc being conveyed from coming into contact with the protruding turntable, hold the turntable at a position lower than the disc in the magazine and drop the conveyed disc onto the turntable so as to cover it from above. I was out. At this time, the pair of upper and lower rollers carrying the disc must be retracted from the disc so as not to interfere with the rotation of the disc, but the upper roller does not come into contact with the disc as the disc descends. Therefore, only the lower roller was retracted downward. At this time, since some of the discs are still located in the magazine, it is necessary to increase the thickness of each disc storage portion in order to secure the falling width of the drop in each disc storage portion. Therefore,
There is a problem that the entire magazine becomes thick and it is difficult to make the disk driver thinner.

Further, in the conventional apparatus, the recording / reproducing section side of each partition plate of the magazine is linear and directly faces the disc insertion slot. Therefore, the disc rotating on the turntable easily contacts the partition plates, and it is necessary to further widen the partition plates to prevent the contact. As a result, the entire magazine becomes thicker, and it is more difficult to make the disc driver thinner.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and an object thereof is to enable recording or reproduction without completely pulling out a disc from a magazine, and more than conventional ones. It is to provide a thinned disk driver.

[0008]

To achieve the above object, the disk driver of claim 1 is the conventional disk driver described above, in which the turntable and the clamper are brought close to each other from above and below to clamp the disk. It is characterized in that it is provided with a clamp means and a retracting means for retracting the disc rollers by vertically separating them from each other when the disc is clamped.

According to a second aspect of the present invention, a disk driver is provided with a plurality of disk storage sections for storing one disk each, and each disk storage section is partitioned by a partition plate. On the recording / reproducing section side, using a magazine provided with a cutout portion matching the shape of the disc end portion, with the end portion of the disc positioned in the cutout portion,
It is characterized by recording or reproducing a disc.

[0010]

The present invention having the above structure has the following functions. That is, according to the first aspect of the invention, the turntable and the clamper clamp the disc by vertically approaching each other by the clamp means. Therefore, the turntable is mounted so that the turntable retracts downward and does not come into contact with the disc while the disc is transported, and the disc is scooped up from below after the transport. Therefore, the disc can be transported and clamped on the same surface, and it is not necessary to secure a height for dropping the disc into the disc storage portion. Therefore, the entire magazine becomes thin, recording or playback is possible without completely pulling out the disc from the magazine, and
It is possible to provide a disk driver that is thinner than before.

According to the disk driver of claim 2,
When the disc is rotated, the end of the disc is located in the notch of each partition plate of the magazine.Therefore, when viewed from the vertical direction, the protruding disc end and the recessed partition plate end are combined with a certain spacing. Will be recorded or played. Therefore, there is no partition plate above and below the disc,
Even if the space between the partition plates is narrower than in the conventional case, the disk does not come into contact with the partition plates during rotation.

Further, the apparatus is provided with a control circuit for controlling these drive mechanisms in a predetermined order.

(2) Operation of the embodiment The disc performance using the disc player of this embodiment is as follows.
This is done as follows.

[Mounting of Magazine] First, the disc 2 is inserted into each disc storage portion 16 from the disc insertion opening 18 of the magazine 3. Next, the magazine 3 is inserted into the main body of the apparatus. At the start of mounting the magazine, the cam roller 23 of the lock plate 13 is located on the back side of the eject cam 25 as shown in FIG. 26 is maintained at a position where it can relatively enter the lock groove 22 of the magazine 3. Then, when the magazine 3 containing a plurality of discs 2 is inserted into the magazine storage portion A from the magazine mounting opening 4, the magazine 3 engages with the eject claw 24 and opposes the biasing force of the eject spring 14 to eject the plate 15. Push to the back side and move. Therefore, the cam roller 23, as shown in FIG.
The lock roller 26 moves relatively to the front side of the eject cam 25, and the lock roller 26 is pressed against the left side of the lock groove 22.
When the magazine 3 is inserted all the way into the magazine storage portion A, the lock roller 26 relatively enters the bent portion of the lock groove 22, locks the magazine 3, and the mounting is completed.

[Guidance of Disk Playing Section] Next, the disk playing section B is guided to a position corresponding to each disk 2 in the magazine 3. That is, when the slide link 12 is rotated by the driving force of the driving source controlled by the control circuit,
The slide plates 5 and 6 shown in FIG. 6 slide in mutually opposite directions. At this time, since the disc playing portion B is fixed in the front-rear and left-right directions and can only move up and down, each guide pin 10 moves relatively to a desired horizontal portion in the guide cam grooves 7, 8. And, since each of these horizontal portions is provided at a height corresponding to each disk position in the magazine 3,
The disc playing portion B moves up and down to the desired position of the disc 2 to which the horizontal portion corresponds. As a result, the disc playing section B can take out the desired disc 2 from the magazine 3.

[Conveying Disc to Disc Playing Section B] Next, the disc 2 to be played is conveyed from the magazine 3 onto the turntable 31. That is, first, at the start of disc transportation, as shown in FIG. 13, the power link 61 is in the neutral position. Therefore, as shown in FIG. 11, the roller arm 41 and the roller arm 43 are closed to be close to each other by the action of the arm cam grooves 51 and 53 into which the arm pins 62 and 63 of the front power plate 58 are inserted. In addition, the roller arm 42 and the roller arm 44
Also, as shown in FIG. 12, the rear power plate 6
No. 0 arm pins 66, 67 are inserted into the arm cam groove 5
It is closed by the action of 2,54. Therefore, the disc rollers 36, 37 attached to the tips of the roller arms 41, 42, 43, 44 are closed so as to be close to each other, as shown in FIGS. As a result, the disc rollers 36 and 37 can carry the both sides of the disc 2 sandwiched therebetween.

At the same time, the middle power plate 59 is
As shown in FIGS. 13 and 14, it is located on the front side by the action of the indirect connection cam groove 73 into which the indirect connection pin 72 of the indirect connection arm 71 is inserted. Therefore, the drive plate 30 is, as shown in FIGS. 9 and 14, driven by the action of the drive cam groove 64 into which the drive pin 65 is inserted.
It is located below. Therefore, the drive plate 3
The turntable 31 provided on the 0 is located below. On the other hand, as shown in FIG. 9, the clamper unit 38 includes the clamp cam groove 5 in which the clamp pin 68 is inserted.
It is located above by the action of 7. Therefore, the turntable 31 and the clamper unit 38 are open so as to be vertically separated from each other. Therefore, the turntable 31 protruding upward does not come into contact with the disc 2 being conveyed.

Next, when the power link 61 is rotated to the left by the driving force, the rear power plate 60 is connected to the back side of the power link 61, and therefore moves to the magazine storage section A side. At this time, the end portion of the rear power plate 60 on the magazine storage portion A side comes into contact with the end portion of the load plate 35 that faces the rear power plate 60, and moves the load plate 35 in the same direction. Therefore, as shown by the broken line in FIG.
The other end of the load plate 35 rotates the disc lever 21, and the disc 2 is pushed out from the disc insertion opening 18.

As shown in FIG. 12, the ejected disc 2 is sandwiched between the disc rollers 36 and 37, and the disc rollers 36 and 37 are rotated by the driving force of the drive source controlled by the control circuit. , The disc 2 is conveyed onto the disc playing portion B. Since the disc roller 36 is closer to the disc playing portion B side than the disc roller 37, the disc 2 is guided by the disc roller 36 with the disc roller 37 as a fulcrum.
It is pressed against the upper surface of each of the horizontal portions 7 and 48 and kept horizontal.

Thus, the disc 2 is the turntable 3
Even when moving upward, the states of the disk rollers 36, 37, the turntable 31, and the clamper unit 38 are maintained by the action of the cam grooves 51, 52, 53, 54, 57, 64. Therefore, the disk rollers 36, 3
The disk 7 can be carried while sandwiching the disk 2, and the turntable 31 and the clamper unit 38 do not contact the disk 2 and do not interfere with the transportation.

When the sensor on the disc playing portion B senses that the disc 2 has reached the turntable 31, the driving force of the driving source controlled by the control circuit causes the power link 61 to rotate to the right. Therefore, each cam groove 51, 5
By the action of 2, 53, 54, 57 and 64, the disc rollers 36 and 37 are opened so as to be separated from each other in the vertical direction and retracted from the disc, as shown in FIG. In synchronization with this, the turntable 31 and the clamper unit 38
Close as shown in FIG. Therefore, the turntable 31 is mounted so that the disc 2 is scooped up from below. Further, the clamper unit 38 fixes the disc 2 so as to press it onto the turntable 31 from above. This allows the disc 2
Is fixed on the turntable 31 at the same height, and the disc transportation to the disc playing portion B is completed.

On the other hand, the disc rollers 36 and 37, which are separated vertically as described above, do not contact the disc 2 in this state and do not interfere with the disc performance. Even in this state, a part of the disc 2 remains in the magazine 3,
The end portion of the disk 2 is located in the cutout portion 19 of the partition plate 17. Therefore, there is no partition plate 17 above and below the disk 2, and the disk 2 does not come into contact with the partition plate 17 even if the disk 2 rotates for playing.

[Transfer of Disc to Magazine] The disc 2 which has finished playing is conveyed into the magazine 3 and returned to the original disc storage rack 16. That is, the power link 6
1 returns to the neutral position again and each cam groove 51, 52, 5
By the action of 3, 54, 57 and 64, the turntable 31 and the clamper unit 38 are opened so as to be vertically separated from each other as shown in FIG. 9, and the disc roller 36 and the disc roller 37 are separated from each other. As shown in
Close again close to each other.

For this reason, the turntable 31 and the clamper unit 38 do not contact the disc 2 and do not interfere with the transport of the disc 2, so that the disc 2 remains at the same height between the disc rollers 36 and 37. Be caught. The disc rollers 36 and 37 are rotated in the opposite direction to the disc 2 conveyance to the magazine 3, the disc 2 is conveyed into the magazine 3, and the disc 2 conveyance to the magazine 3 is completed.

[Magazine Ejection] When ejecting the magazine 3, the slide link 12 shown in FIG.
Slide in opposite directions. Therefore, each guide pin 10 relatively moves toward the lower ends of the guide cam grooves 77 and 8. At this time, the connecting pin 3 of the slide link 12
As shown in FIG. 8, 3 is in contact with the disc playing portion B side of the connecting hole 32 of the slide plate 75 by the urging force of the connecting spring 34.

When each guide pin 10 inserted into the guide cam groove 8 approaches the extension portion 9 as shown in FIG. 18, the guide pin 10 inserted into the guide cam groove 77 is shown in FIG. As shown, it abuts on the end of the guide cam groove 77.
Therefore, the slide plate 75 stops at that position. When the slide link 12 is further rotated rightward, as shown in FIG.
As shown in, the connecting pin 33 moves away from the disc playing portion B side of the connecting hole 32 and moves toward the magazine storing portion A side.

When the slide link 12 is rotated up to this point, as shown in FIG. 4, the eject pin 28 of the slide link 12 comes into contact with the lock plate 13 and moves the lock plate 13 to the disc playing portion B side. Therefore, the lock roller 26 of the lock plate 13 is released from the bent portion of the lock groove 22 of the magazine 3 and the lock is released, so that the magazine 3 is ejected from the magazine mounting port 4 by the eject plate 15, and the eject of the magazine 3 is prevented. finish.

(3) Effect of Embodiment As described above, according to this embodiment, the turntable 31 is provided.
Is retracted downward when the disc is being transported and the disc 2
Mount the disc 2 so that it does not come into contact with and is picked up from below. Therefore, it is not necessary to secure a height for dropping the disc 2 into each disc storage rack 16. That is, when dropping a disc as in the past,
A drop stroke (about 4 to 5 [mm]) that is equal to or greater than the height of the disc fitting protrusion of the turntable is required. However, when the disc does not need to be dropped as in the present embodiment, the drop stroke is not necessary. Becomes If multiple discs can be loaded using a magazine,
It is possible to reduce the thickness by the number of discs × the drop stroke (about 24 to 30 [mm] in the 6 disc storage type). Therefore, it is possible to provide a disc driver which is thinner than the conventional one and which can perform recording or reproduction without completely pulling out the disc 2 from the magazine 3 and which is thinner than the conventional one.

Further, since the end portion of the disc 2 during rotation is located at the notch of each partition plate 17 of the magazine 3, there is no partition plate 17 above and below the disc 2, and the spacing between the partition plates 17 is smaller than in the conventional case. Even if the disc becomes narrow, the disc 2 does not come into contact with the partition plate 17 during rotation. Therefore, it becomes easier to make the disk driver thinner.

Particularly, according to this embodiment, the disk rollers 36 and 37, the turntable 31, the clamper unit 3 are provided.
All of the opening and closing movements of No. 8 are controlled by any of the three cam plates of the front power plate 58, the middle power plate 59, and the rear power plate 60. Also,
These front power plate 58, middle power plate 59,
All of the rear power plates 60 are connected to and driven by a single power link 61. Therefore, according to the present embodiment, the disc rollers 36 and 3 that open and close respectively.
The 7, turntable 31, and clamper unit 38 can be realized with a simple configuration.

(4) Other Embodiments The present invention is not limited to the above embodiments, but includes the following other embodiments. For example, the retracting means of each disc roller and the clamping means of the turntable and the clamper unit are not limited to the configuration in which they are synchronized by the cam plate, and they can be controlled by other means. For example, each disk roller 36, 37, turntable 31, and clamper unit 38 can be provided with a driving means such as an actuator, and each driving means can be individually controlled by a control circuit.

Further, even when the cam plate is used, the mounting position of each shaft of each roller arm, clamp arm or drive plate and the shape of the cam groove of each arm can be appropriately changed.
