Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is capable of loading a plurality of cartridges each containing a disk-shaped information recording medium (hereinafter referred to as a disk), and any one of the cartridges can be loaded. The present invention relates to a so-called autochanger type disk drive device that records and reproduces information signals on and from a selected built-in disk.

Conventional Technology Conventionally, the main method for autochangers that selectively drives one of multiple discs is to place multiple discs on one tray and rotate the tray to select the disc. The carcell type to be performed,
There is a disk magazine type in which a plurality of disks are loaded into a magazine, the magazine is inserted into a drive device, and disks are selectively taken out from the magazine and driven. These are mainly compact discs (hereinafter referred to as C
Write it as D. ), and a conventional example of the above-mentioned car cell type is disclosed in Japanese Patent Application No. 1-54034, and a conventional example of the disk magazine type is disclosed in Japanese Patent Application Laid-open No. 103466/1983, for example.

has been released, and the spread of 8cm CDs in particular is rapidly progressing.In line with this, an autochanger-type disc drive device that can drive two types of discs with different diameters with the same device has been developed, and will become the mainstream in the future. It is expected that

Problems to be Solved by the Invention However, in the conventional disk drive device described above, a plurality of disks are loaded in the same tray or magazine, and in the case of a carousel type, the disks are arranged on the same plane, so the dimensions of the tray are The number of disks that can be loaded is limited due to physical constraints, and the disk magazine type has the disadvantage that it is not possible to increase the number of disks that can be loaded due to dimensional constraints of the magazine. In other words, when attempting to increase the number of disks to be loaded, there is a problem in that the size and thickness of the disk drive device increases.

Means for Solving the Problems In response to these problems with conventional disk drive devices, the inventor focused on the fact that autochangers capable of driving the two types of disks mentioned above would become mainstream, and loaded them into disk drive devices. We considered increasing the number of discs that can be loaded by changing the orientation of the disc depending on its diameter. In order to realize this, the disk drive HW of the present invention includes a spindle motor for rotationally driving the disk, a pickup for recording or reproducing information signals on the disk, and a pickup for moving the pickup in the radial direction of the disk. a first base on which the spindle motor, the pickup, and the transfer means are mounted; the first base is rotatably supported and mounted, and the first base is rotatably supported; The device includes a second base that is capable of reciprocating movement, and the only driving means that rotates the first base and reciprocates linearly the second base.

Further, the driving means is provided with a fixed base, and a first pulley having a connecting portion on the outer circumference and rotatably supported on the fixed base;
an engaging portion provided on a first base and capable of engaging with and disengaging from a connecting portion of the first pulley; a second pulley rotatably supported on the fixed base; and a transmission means that is stretched between the second pulley and has a portion fixed to the engaging portion, and a drive motor that drives the transmission means.

Effect: With the above-described configuration, two types of disks loaded in at least two different orientations in the same disk drive device can be driven and played by the same pickup, pickup transport means, and spindle motor. As a result, specifically, a disk with a relatively large diameter (12cmC
By loading the discs D) horizontally and the smaller diameter discs (8 cm CD) vertically, the total number of discs that can be loaded can be increased without making the disc drive device thicker.

Hereinafter, the disk loading operation of the disk drive device of this embodiment will be explained with reference to the drawings.

First, the cartridge loading operation will be explained using FIGS. 1, 4, and 18 to 20.

The cartridge 100 containing the small-diameter disk 2 is loaded into the slot 11 through the insertion opening 11a of the cartridge accommodating portion 10 exposed to the operation panel 3a.

Here, the cartridge 100 is loaded in such a position that the notch 103 faces the base plate 3b of the disk drive device 3 and the opening 104 is located inside the disk drive device 3, as shown in FIG. When the cartridge 100 is inserted in the direction of arrow N to a predetermined position, further insertion is restricted by stoppers ISa and 15b provided near the outlet ILb of the slot 11.
Loading is complete.

At this time, the label area 105 of the cartridge 100 is located near the insertion opening 11a of the cartridge storage section 10 and is visible from the outside. Therefore, the operator writes the contents of the small-diameter disk 2 stored in the cartridge 100 on a label, and writes this on the label area 10.
5, even if the cartridge 100 is loaded in the cartridge storage unit 10, that is, the disk drive device 3, the contents can be known without taking out the cartridge 100.

Furthermore, when the cartridge 100 is fully loaded, the notch 103 is in the notch 1 of the cartridge storage section 10.
6, and the small-diameter disk 2 can be removed by the pull-out lever 67 through the notches 103 and 16.

Next, referring to FIGS. 2 to 4, an explanation will be given of the operation when reproducing a disc placed on the tray 5. Although the above-mentioned disk may be either the large-diameter disk 1 or the small-diameter disk 2, the case where the large-diameter disk 1 is placed will be explained here.

First, in the initial state, the second base 40 is the guide base 6
It is located at the leftmost position on 0 (first position date). Further, the first base 20 mounted on the second base 40 is held in a horizontal position. Further, the roller base 60 comes into contact with the position regulating member 52 and is regulated from moving to the left.

The tray 5 is connected to the disk drive device 3 through the tray ejection window 4.
is discharged outside. When the operator places the large-diameter disk 1 in the large-diameter recess 5a of the tray 5 and performs a predetermined operation, the tray 5 relays from the ejection position C to the standby position B while maintaining a substantially parallel attitude to the base plate 3b. Playback position A
Continuously move up to.

Here, the movement path from the discharge position C to the standby position B is a straight path in the horizontal direction. Next, the disk placed above the playback position A from the standby position B is moved to the spindle motor 3.
It moves in the horizontal direction until it comes to a position concentric with the drive shaft 32a of Base Play) 3b, and then starts descending in a substantially perpendicular direction with respect to the base play) 3b. When the tray 5 descends to the position of the turntable 31, the large-diameter disk 1 on the tray 5 is placed on the turntable 31. Thereafter, as only the tray 5 further descends, the clamper arm 7 rotates in the direction of the arrow, and the first clamper 6 presses the large diameter disk 1 against the turntable 81, thereby performing disk clamping. At the same time, a centering hub 31a built into the turntable 31 fits into the center hole of the large-diameter disk 1 to center it.

With the above operations, mounting of the large-diameter disk 1 using the tray 5 is completed.

As is clear from the explanation up to this point, in the disk drive device of the present invention, the large diameter disk 1 is mounted in the disk drive device 3 in a substantially horizontal posture by the tray 5 that moves in and out in the horizontal direction, and the small diameter disk 2 is mounted in a vertical position, that is, at an angle of approximately 90 degrees with respect to the large diameter disc 1. In this case, the width direction of the disk drive device 3 corresponds to the thickness direction of the cartridge 100 in which the small diameter disk 2 is stored. If you try to increase the number of cartridges 100 that can be loaded, the required storage space, that is, the cartridge storage section 10, will increase in size, but the direction of size expansion is in the width direction of the disk drive device 3, and it is difficult for the disk drive device 3 to have a layout. This is a direction with plenty of room. On the other hand, the width direction of the cartridge 100 corresponds to the thickness direction of the disk drive device 3, and the dimension in the same direction is determined by the width dimension regardless of the number of cartridges 100 loaded. The cartridge 100 stores a small diameter 8cm CD,
The external dimensions of the cartridge 100 are equivalent to the thickness of a conventional disk drive device. In other words, by arranging the large-diameter disk 1 and the small-diameter disk 2 in the above-described posture, the number of disks that can be installed can be dramatically increased while keeping the size (external dimensions) of the disk drive device the same as before. be able to.

On the other hand, the above explanation of the operation of the tray 5 is for the case where the second base 40 and the roller base 80 are in a predetermined initial state, but the operation when the initial state is different from the above explanation is as follows. It is.

For example, if the first base 20 is in a vertical position as shown in FIG. 6, or if the second base 40 is not at the left end of the guide base 50 as shown in FIG. When the operator performs a predetermined operation for moving the tray 5 from the position B protruding outside the disk drive device 3 (ejection position C), the tray 5 moves from the ejection position C to the standby position B, There it becomes a standby state. An instruction means (not shown) in the disk drive device 3 issues an instruction to return the first base 20 and the second base 40, and after they have returned to the first position shown in FIG.
The operation is restarted, and the mounting of the large-diameter disk 1 is executed.

When the installation of the large-diameter disk 1 is completed, it becomes possible to reproduce information signals from the disk. Upon receiving the instruction from the instruction means, the spindle motor 32 rotates and drives the large diameter disk 1 to rotate. Further, the traverse motor 33 rotates and moves the pickup 30 in the radial direction of the large diameter disk 1 via a gear train, thereby performing disk access. The pickup 30 reads and reproduces information signals recorded on the large-diameter disk 1, and the spindle motor 32 is rotationally controlled so that the circumferential speed of the disk at the information position to be reproduced by the pickup 30 is constant.

Next, each operation will be explained from a state in which a large diameter disc 1 placed horizontally is being played to a state in which a small diameter disc 2 stored in the cartridge 100 is being played.

FIG. 5 is a plan view showing the disk drive device of the present invention when a disk placed in a vertical position is being played back, FIG. 6 is a front view thereof, FIG. 7 is a side view thereof, and FIG. 13 is an operation diagram when the first base is in a horizontal position,
Figure 4 is an operation diagram when the first base is in a vertical position, Figure 5 is a perspective view when the first base is in a horizontal position, and Figure 16 is an operation diagram when the first base is in a vertical position. FIG.

Now, when the operator performs a predetermined operation from the state shown in FIGS. 2 to 4, the rotation of the spindle motor 32 is stopped, and the rotation of the large diameter disk 1 is stopped. Thereafter, the clamper arm 7 rotates upward, and the turntable 31 releases its pressure on the disk 1. The tray 5 starts rising from the playback position A while maintaining an attitude substantially parallel to the base plate 3b. When the tray 5 rises to the position of the turntable 31, the disc 1 is placed in the large diameter recess 5a of the tray 5.
will be placed on. The tray 5 further rises and reaches the tray ejection window 4.
When it rises to a height of , it moves horizontally to the standby position B, and the transfer operation is completed. Thereafter, by the operator performing a predetermined operation, the tray 5 can be freely reciprocated between the standby position B and the ejection position C, and the disc 1 can be easily taken out.

On the other hand, when the tray 5 comes to the standby position B, the drive motor 53 rotates and transmits rotational driving force to the intermediate gear 55, and further to the drive boob IJ56. Drive pulley 5
6 rotates, the rotation is transmitted to the driven pulley 57 via the wire 58.

Next, the rotation operation of the first base 20 will be explained.

When the driven pulley 57 rotates in the direction of arrow R, the first base 2
Since the engagement protrusion 22 of 0 and the engagement groove 57b of the driven pulley 57 are engaged, the first base 20 is
It rotates integrally with the driven pulley 57 around the center. In addition,
Since the driven pulley 57 is pivotally supported on the drive base surface 50a, the center of rotation of the first base 20 does not move. That is, the second base 40 rotates in the direction of arrow R around the rotation support shafts 23a, 23b of the first base 20 while remaining stationary.

Here, when the first base 20 is held in a horizontal position, the first crimping member 24 of the first base 20 is crimped to the upper crimping surface 40a of the second base 40 due to the biasing force of the reversing spring 47. be done. On the other hand, when the first base 20 is held in a vertical position, the second crimp surface 25a of the L-bulging protrusion 25 formed on the first base 20 is pressed against the second base by the biasing force of the reversing spring 47. 40
It is crimped onto the lower crimping surface 40b of.

Therefore, the first base 2 is integrated with the driven pulley 57.
0 rotates 90 degrees and the second crimp surface 25a of the first base 20 is crimp-bonded to the lower crimp surface 40b of the second base 40, the first
Rotation of the base 20 is prevented, and the base plate 3
It is held in a position substantially perpendicular to b.

The first base 20 is held in a vertical position, and the drive motor 5
3 further rotates to pull the engagement protrusion 22 in the direction of arrow S, and the second base 40 slides along the guide rod 51. Here, when the second base 40 slides, the guide rollers 44 of the second base 40 roll on the roller contact surface 5ob of the guide base 50 while the first base is biased to a vertical position. 20 while performing sliding movement. As the second base 40 slides, the engagement protrusion 22 of the first base 20 and the engagement groove 57b of the driven pulley 57
are removed, and the second base 40 continues to slide.

FIG. 8 is a plan view showing a state when the first base and the roller base are connected in the disk drive device of the present invention;
FIG. 9 shows its front view.

In FIGS. 8 and 9, when the drive motor 53 rotates further, the second base 40 reaches the connection position where the position regulating member 52 is arranged. Here, the position regulating member 5
2 is fixed to the base plate 3b, and the roller base 6,
O prevents excessive movement to the left.

At the connection position, a roller base 60 that is slidably engaged with the guide rod 51 is waiting, and a second roller base 60 that is slidably moved is waiting.
The base 40 contacts the roller base 60. Furthermore, the second
The magnet 45 of the base 40 (the rectangular part with left-down inclined hatching) and the metal piece 61 of the roller base 60 (the rectangular part without hatching) are coupled to each other by magnetic attraction, and the second base 40 and The roller base 80 is connected.

After the second base 40 is connected to the roller base 60, it continues to slide along the guide rod 51. Here, when the roller base 60 slides, the guide roller 44 supported by the roller base 60 moves toward the guide base 50.
The posture of the roller base 44 is maintained while rolling on the roller rolling contact surface 50b.

Here, the second base 40 can select an arbitrary cartridge in the cartridge accommodating section 10 and move it to its removal position upon receiving an instruction from an instruction means (not shown). Here, the operation when the cartridge 100 loaded on the right end of the guide base 50 is selected will be described.

FIG. 10 is a plan view showing the disk drive device of the present invention when a disk placed in a vertical position is being played back, FIG. 11 is a front view thereof, and FIG. 12 is a side view thereof.

10 to 12, the drive motor 53 further rotates, and the second base 40 reaches the position of the cartridge 100 that stores the small-diameter disk 2 while maintaining the connection with the roller base 60 (the second position). In this state, the first base 20 can reproduce the selected small-diameter disc 2 in a posture that makes an angle of approximately 90 degrees with respect to the reproduction posture of the large-diameter disc 1. The moving operation of the second base is completed in the above manner. Here, when the roller base 60 is slidingly moving, the hook portion 87a of the pull-out lever 67 moves under the notch 16 formed in the cartridge storage portion 10.

Next, the operation related to ejecting the disc will be explained.

10 to 12, 17, and 18, when the sliding movement of the second base 40 is completed, the pull-out lever 6
7 is driven by a pull-out lever driving means (not shown), and the claw 102a of the slide arm 102 of the cartridge 10o loaded in the slot 11 is engaged and moved in the direction of arrow P by the hook portion 67a of the pull-out lever 67. When the pull-out lever 67 engages and moves, the end 102b of the slide arm 102 comes into contact with the side surface of the small-diameter disk 2, and the small-diameter disk 2 is ejected to the outside through the opening 104 of the cartridge lid.

The ejected small-diameter disk 2 is held between the first pull-out roller 64a and the first pull-out roller 64b, and is further transferred in the direction of arrow P as the first pull-out rollers 84a and 64b rotate. The second pull-out roller 65b is pressed against the second pull-out roller 65a by a pinch arm 66, and the small diameter disk 2 is held between them. Thereafter, as the second pull-out rollers 65a and 65b rotate, the small-diameter disk 2 is further regulated by the linear guide portion θ2a as shown by the arrow P.
The disc is moved in the direction of , and comes into contact with the centering guide portion, thereby preventing the disc from moving. After that, the first bowed rollers 64a, 6
4b and the second pull-out rollers 65a and f35b stop rotating, and the disk transport operation ends.

The small-diameter disk 2 is held between the second pull-out roller 65a and the second pull-out roller 85b, and is moved to the clamper arm 70.
rotates in the axial direction of the second clamper 63, and the second clamper 63 of the clamper arm 70 presses the small diameter disk 2 against the turntable 31. After that, pinch arm 68
rotates the second pull-out roller 25b in a direction to release the pressure on the second pull-out roller E35a, and the small-diameter disk 2 is released from being held. In the manner described above, the disk clamping operation of the small diameter disk 2 is completed.

When the clamping of the small-diameter disk 2 is completed, it becomes possible to reproduce information signals from the disk.

Upon receiving an instruction from an instruction means (not shown), the spindle motor 32 rotates and drives the small diameter disk 2 to rotate. Further, the traverse motor 33 rotates and moves the pickup 30 in the radial direction of the small diameter disk 2 via a gear train, thereby performing disk access. The pickup 30 reads and reproduces information signals recorded on the small-diameter disk 2, and the spindle motor 32 is rotationally controlled so that the circumferential speed of the disk at the information position to be reproduced by the pickup 30 is constant.

Here, in FIGS. 12 and 18, when the small-diameter disc 2 is being played, the pull-out lever 67 is moved by the arrow P.
Since the slide arm 102 is locked in the direction of the cartridge 100 and the cartridge 100 is locked between the pull-out lever 67 of the roller base 60 and the stoppers 15a and 15b of the cartridge storage section 10, the cartridge 100 is not inserted into the outside of the disk drive device 3. Evacuation becomes impossible. On the other hand, cartridges that are not being regenerated (not indicated by numbers) are removed from the drawer lever 67.
Since the disk drive device 3 is not locked between the stopper 15al and the stopper 15b, it is possible to eject the disk drive device 3 to the outside and load it into the slot 11 of the cartridge storage section 10.

Next, the operation when storing the small-diameter disk 2 in the cartridge 100 will be explained.

10 to 12 and 17, the rotation of the spindle motor 32 is stopped, and the rotation of the small diameter disk 2 is stopped. Thereafter, the pinch arm 66 rotates the second pull-out roller 85b toward the second pull-out roller 65a, thereby pinching the small-diameter disk 2. When the small-diameter disk 2 is clamped between the second pull-out roller 85a and the second pull-out roller 65a, the clamper arm 70 rotates in a direction away from the turntable 31, and the second clamper 63 clamps the small-diameter disk 2. is canceled. Next, when the second pull-out rollers 66a and 85b rotate, the small-diameter disk 2 is transferred toward the empty cartridge 100 to be stored, and begins to be inserted into the cartridge 100 through the opening 104. Furthermore, second pull-out rollers 65a, 8
6b rotates, the small diameter disk 2 reaches a position where it abuts the end 102b of the slide arm inside the cartridge 1oO. At this point, the second pull-out rollers 65a, 8
5b is released, and the small diameter disk 2 is replaced by the first
It is now in a state where it is transported by the pull-out rollers 64a and 84b. Thereafter, the pull-out lever 67 moves in the direction of the operation panel 3a, and the small-diameter disk 2 is transferred by the first pull-out rollers 64a, 64b.
is stored inside the cartridge 100.

The above explanation has been about the operation from a state in which the large-diameter disc 1 placed horizontally can be played back to a state in which the small-diameter disc 2 can be played in an attitude substantially perpendicular thereto. On the contrary, the operation from the state where the small diameter disc 2 can be played back to the state where the large diameter disc 1 can be played is basically the reverse of the above operation. That is, the drive motor 5
3 rotates, the rotational driving force is transmitted, and the driven pulley 57 rotates in the direction opposite to the arrow R, the second base 40 and the roller base 60 are integrally driven and moved to the left. When the roller base 60 reaches the position of the position regulating member 52 and comes into contact with it, the second base 40 and the roller base 60
The connection with the second base 4Q is released, and only the second base 4Q continues to move. When the second base 40 reaches the leftmost end of the guide base 50, the engagement protrusion 22 of the first base 20 and the engagement groove 57b of the driven pulley 57 engage with each other. At this point, the movement of the second base 40 is stopped, and the rotation of the first base 20 is started. When the first base 20 rotates until it assumes a horizontal position, the driven pulley 57 stops and the operation is completed.

Regarding the detailed operation, it will be easier to explain the operation from the state in which the large-diameter disc 1 placed horizontally can be played to the state in which the small-diameter disc 2 can be played in a substantially perpendicular position. Since it is easy to understand, the explanation here is omitted.

In this embodiment, it has been described that the second base 40 and the roller base 60 are magnetically connected and disconnected by the magnet 45 and the metal piece 61, but any other device can be used as long as the same attachment/detachment effect can be obtained. It doesn't matter what it is.

Further, the large diameter disc 1 and the small diameter disc 2 of this embodiment were at approximately 90 degrees to each other in their playback postures, but
This angle is not limited to 90 degrees, and may be set to any angle that is easy to design in accordance with the gist of the present invention.

Effects of the Invention As described above, the disk drive device of the present invention includes a first base on which a spindle motor, a pickup, and a means for transporting the pickup are mounted, and the first base is rotatably supported and mounted. Since it is equipped with a second base that can reciprocate linearly, each of the two types of disks loaded in the same disk drive device in at least two different orientations can be moved by the same spindle motor, pickup, and pickup. It can be driven and regenerated by means of transport.

Then, a disk with a relatively large diameter is placed horizontally,
By vertically loading disks with smaller diameters, the total number of disks that can be loaded can be increased without increasing the size of the disk drive device.

Further, since the rotation of the first base and the reciprocating linear movement of the second base are performed by a single driving means, it is possible to reduce the number of parts and downsize the device.
