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 to a predetermined position in the direction of the arrow N, a stopper 15at 15b provided near the outlet itb of the slot 11 restricts further insertion, and loading is completed.

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, the contents of the cartridge 100 can be known without taking it out, even if the cartridge 100 is loaded in the car IJ storage unit 10, that is, the disk drive device 3.

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 5
0 (first position). 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 moves from the ejection position C to the standby position B while maintaining a substantially parallel attitude to the base plate 3b. Relay 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 from the standby position B to the top of the playback position A 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 indicated by the arrow, and the first clamper 6 presses the large diameter disk 1 against the turntable 31, 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, the loading of the large-diameter disk IQ using the tray 5 is completed.

As is clear from the above description, in the disk drive device of the present invention, the large-diameter disk 1 is mounted on the disk drive device 3 in a substantially horizontal position by the tray 5 that moves in and out horizontally, and the small-diameter disk 2 is mounted in a substantially horizontal position. In a vertical position,
That is, it is mounted at an angle of approximately 90 degrees with respect to the large diameter disk 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, disk drive device 3
The width direction of the IJ edge 100 corresponds to the thickness direction of the cartridge 100, but the dimension in the same direction is determined by the width dimension regardless of the number of loaded cartridges 100. The cartridge 100 stores a small-diameter 8 cm CD, and 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 60 are in a predetermined initial state, but the operation when the initial state is different from the above explanation is as follows. be.

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 executes a predetermined operation for moving the tray 5 from the state where it protrudes outside the disk drive device 3 (ejection position C), the tray 5 moves from the ejection position C to the standby position B, and waits there. state. A return instruction for the first base 20 and the second base 40 is issued from an instruction means (not shown) in the disk drive device 3, and after they have returned to the first position shown in FIG. 2, the tray 5 operates. is restarted, and 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 5 of the tray 5.
It is placed on a. When the tray 5 further rises to the height of the tray ejection window 4, it moves horizontally to the standby position B, completing the transfer operation. After that, the operator performs a predetermined operation to move the tray 5 to the standby position B and the ejection position C.
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 pulley 56. Drive pulley 56
When rotates, the rotation is transmitted to the driven pulley 57 via the wire S8.

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

When the driven pulley 57 rotates in the upward direction of the arrow, 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 crimp surface 24 of the first base 20 is crimp-bonded to the upper crimp 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
The rotation of the base 20 is prevented, and the base brake) 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 50b 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 S3 further rotates, 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 1-3b, and the roller base 6
0 prevents excessive movement to the left.

At the connection position, a roller base 6o that is slidably engaged with the guide rod 51 is waiting, and a second roller base 6o 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 60 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.

In FIGS. 10 to 12, the drive motor 53 rotates further, and the second base 40 maintains connection with the roller base 60 while storing the small diameter disk 2 (IJ).
100 (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 sliding, the pull-out lever 67
The hook portion 87a moves under the notch 16 formed in the cartridge storage portion 10.

Next, we will explain the operation related to ejecting the disc. In Figs.
7 is driven by a pull-out lever driving means (not shown), and the claw 102a of the slide arm 102 of the cartridge 100 loaded in the slot 11 is engaged and moved in the direction of arrow P by the hook portion 87a 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 85a by a pinch arm 66, and the small diameter disk 2 is held between them. Thereafter, as the second pull-out rollers 65a and 85b rotate, the small-diameter disk 2 is further regulated by the linear guide portion 82a and further moved toward the point indicated 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 pull-out roller E34a,
64b and the second bow rollers 65a and 65b stop rotating, and the disk transfer operation ends.

The small-diameter disk 2 is held between the second pull-out roller 85a 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 66
rotates the second pull-out roller 25b in the direction of releasing the pressure on the second pull-out roller 65a, 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.
Because it is not locked between the stoppers 15a and 15b,
Ejection of the disk drive device 3 to the outside and loading into the slot 11 of the cartridge storage section 10 becomes possible.

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. After that, the pinch arm 66 rotates the second pull-out roller 65b in the direction of the second pull-out roller f35a,
The small diameter disk 2 is held. When the small-diameter disk 2 is held between the second pull-out roller 65a 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 65 a and 65 b 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, the second pull-out roller 85
When a, 65 b rotate, the small diameter disk 2 is moved to the end 102 of the slide arm inside the cartridge 100.
It reaches the position where it contacts b. At this point, the grip between the second pull-out rollers 65a and 85b is released, and the small-diameter disk 2 is now in a state of being transferred by the first pull-out rollers 84a and 64b instead. Thereafter, the pull-out lever 67 moves toward the operation panel 3a, and the first pull-out roller 8
4a and 84b, the small-diameter disk 2 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 40 is released, and only the second base 40 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 is 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 this is easily understood, the explanation here will be 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 within the scope of the invention.

Effects of the Invention As described above, in the disk drive device of the present invention, a plurality of cartridges each storing one disk therein are detachably attached to each other, and at least a portion of each of the cartridges is visible from the outside. a storage means that can be loaded into the storage means; and an ejection means for selectively taking out a disk from the cartridge loaded in the storage means;
The storage device is equipped with a recording/reproducing means for recording or reproducing an information signal on the taken-out disc, and a locking means for locking the cartridge from which the disc has been taken out so that it cannot be taken out from the storage means. The cartridges can be viewed from the outside even when loaded into the drive device, and if a label is attached, the contents can be identified individually. Moreover, each cartridge can be taken out from the drive device at will, except for the cartridge in which the disk has been taken out into the drive device. On the other hand, since the cartridge with the disk taken out into the drive device is locked in the storage means,
This prevents the mistake of accidentally removing just the cartridge.
