[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive for driving a disk-type recording medium (hereinafter, referred to as a CD) such as a CD (compact disk), a CD-ROM, or a magneto-optical disk. The present invention relates to a disk drive capable of driving a CD having a size.

[0002]

2. Description of the Related Art CDs are used as computers and other external storage devices. Recently, as a disk drive device for driving the CD, an opening / closing lid provided in the drive device body or a drive device body has been used. On the other hand, there is provided a system in which a CD is automatically set in a drive device when a CD is held on a tray that appears and disappears. In this type of drive device, a holder for guiding the peripheral portion of the CD is provided on the opening / closing lid or the tray. If the CD is held by this holder, the opening / closing lid is closed thereafter, or the tray is moved to the drive device side. When the CD is moved, the CD is automatically set in the drive device with the center hole of the CD guided by the guide taper of the turntable.

In recent years, an 8 cm CD having a diameter smaller than that of a 12 cm CD has also been provided. In a disk drive of this type, these 12 cm CDs and 8 c
It is required that both mCDs can be driven. In this case, the 8 cm C
When D is held on the tray, the center hole of 8 cmCD may not be able to be correctly guided to the guide taper of the drive device due to the difference in diameter from the 12 cmCD.

[0004] Therefore, an apparatus for changing the position of the holder has been proposed in the past. For example, Japanese Utility Model Application No. 5-5963
In JP-A-9, a holding portion for an 8 cm CD is provided so as to be movable with respect to an opening / closing lid of a drive device, and a 12 cm CD is provided.
In the case of D, the holding portion for the 8 cm CD is retracted to use the holding portion for the 12 cm CD, and in the case of 8 cm CD, the holder for the 8 cm CD is moved forward so that the 8 cm CD is held.
The center hole of the CD is set at the same position as the 12 cm CD. A similar technique is disclosed in Japanese Utility Model Application 1-15.
It is also proposed in Japanese Patent Publication No. 1452, and has a configuration in which a holder as a holding portion can be advanced and retracted by an operation lever.

[0005]

In such a conventional configuration, the mechanism for changing the position of the holder is relatively complicated, and the operation for changing the position is also complicated. . Further, these conventional techniques have a configuration in which a CD is held by a tiltable opening / closing lid. In such a configuration, the CD may be held in an inclined state along the opening / closing lid. When the center hole of the CD is set at a predetermined position, only the lower edge of the CD may be held by the holding unit or the holder. However, in a drive device having a vertical structure in which it is required to hold a CD in a vertical state with respect to a tray in a vertical state, the CD is
Cannot be held in an inclined state, the conventional structure described above cannot be used as it is, and the configuration of the holder tends to be complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a disk drive capable of simplifying the structure of a holder and facilitating a position setting operation thereof and setting a CD having a different diameter to a vertical disk drive. Is to provide.

[0008]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment in which the present invention is applied to a CD-ROM drive device which is an external storage device of a computer. A rectangular tray 3 is configured to be able to protrude and retract from a drive device main body 4 through a rectangular slit 2 provided on a front panel of the CD-ROM drive device 1. The CD-ROM 100 is held along the inner surface of the vertical bottom wall 5 of the tray 3, and the tray 3 is stored in the drive device main body 4 while maintaining the held state, thereby holding the CD-ROM 100 on the tray 3. C
The D-ROM 100 is pressed from behind by the pressing device (not shown) toward the drive device main body.
The center hole 101 of the ROM is guided to a guide taper of a turntable (not shown) in the drive device main body 4, and is integrated therewith and driven to rotate. Since the driving mechanism itself is already widely known, a detailed description is omitted here.

The bottom wall 5 of the tray 3 is provided with a center window 6 required for pressing a CD against the turntable of the drive unit body. A pair of arc-shaped windows sandwiching the center window 6 is provided. Holders 7 and 8 are provided so as to oppose in the vertical direction. These holders 7 and 8 are CD-RO
By sandwiching the opposite peripheral region of M100, CD-RO
M can be held such that its center hole 101 is at a predetermined position. As shown in FIG. 2, the holders 7 and 8 have arc walls 71 and 81 along their outer edges.
Are integrally formed as plate-like member holder pieces 72 and 82. The arc walls 71 and 81 are, for example, 12 cmC.
D having a curvature corresponding to the circumferential curvature of the holder piece 7.
2, 82, it stands vertically from the surface. The holder pieces 72, 82 are housed in a pair of cutouts 51, 52 provided at positions sandwiching the center window 6 of the tray bottom wall 5, and are L-shaped provided on both sides of the holder pieces 72, 82. By engaging the guide projections 73 and 83 with the inner edges of the notches 51 and 52, the holders 7 and 8 can be attached to the notches 51 and 52, respectively.
Can be moved in the radial direction of the tray bottom wall. In this case, since the guide projections 73 and 83 are frictionally engaged with the inner edges of the notches, when the holders 7 and 8 are moved along the notches 51 and 52, the frictional force causes the respective holders 7 and 83 to move. Reference numeral 8 indicates the moving position.

On the back side of each of the holder pieces 72, 82, one rod 74, 8 is provided so as to face each other.
4 protrudes in the radial direction and extends along the back surface of the tray bottom wall 5. Micro racks 75 and 85 are formed on the opposing surfaces of the rods 74 and 84, and the racks 75 and 85 are supported on the back surface of the tray bottom wall 5 at a position sandwiched between the rods. The pinions 9 are engaged with each other at circumferential positions on opposite sides.

According to this configuration, as shown in FIG.
When a 12 cm CD 100A is set in the drive device 1, the holders 7, 8 are notched 51,
52, if it is moved to the outermost position,
Eight arc walls 71 and 81 are opposed to each other at an interval of 12 cm. Therefore, a 12 cm CD is provided between the holders 7 and 8.
-If the ROM 100A is held, the periphery of the CD-ROM is held in a state of being sandwiched between the upper and lower peripheral regions by the arc walls 71, 81 of the holders 7, 8, and the CD-ROM is in the vertical state. However, the tilt can be prevented, and the tray 3 can be made to enter the drive device 1, so that the center hole 101 of the 12-cm CD-ROM 100A is correctly guided to the guide taper of the turntable.

On the other hand, when an 8 cm CD-ROM is set, as shown in FIG. 3B, one holder 7 is manually moved toward the center, and a notch 51
To the innermost position. The rack 75 provided on the rod 74 rotates the pinion 9 by the movement of the one holder 7 toward the center, and the rotation of the pinion 9 moves the other rack 85 and the rod 84 in the opposite direction, ie, toward the center. Let it. Rack 75 for both holders,
85 are formed to the same standard, so that the other holder 8
Is moved by the same distance as one of the holders 7, and is moved to the innermost position of the notch 52. As a result, the respective arc walls 71, 81 of the holders 7, 8 are opposed to each other at an interval of 8 cm. Therefore, if the 8 cm CD-ROM 100B is held between these holders, this CD
-The periphery of the upper and lower regions of the ROM 100B is each arc wall 71,
81, the CD-ROM is prevented from tilting even when the CD-ROM is in a vertical state, and the tray 3 can be made to enter the drive device. This allows 8cmC to be placed in the same center hole position as the 12cmCD-ROM.
The center hole of the D-ROM is located and correctly guided to the guide taper of the turntable in the drive device.

As described above, in this holder configuration, when one of the holders is moved, the other holder disposed opposite to the holder moves in the opposite direction about the position where the center hole of the CD-ROM is set. It will be moved by the same distance and its radial spacing will be changed symmetrically with respect to the center hole position. This makes it easy to operate CD-ROM
Can be adjusted, and the CD-ROM can be held vertically. Further, the structure for moving each holder is only required to provide a rod having a rack formed in each holder and to dispose a pinion between the rods, and the structure is extremely simple.

In the above embodiment, two holders are shown. However, if space is possible,
Three or four may be provided at positions equally arranged in the circumferential direction. Further, in the above-described embodiment, the case where the tray is arranged in a vertical state is shown. However, when the CD is held by the tiltable opening / closing lid as in the above-described conventional technique, or the CD is drawn out of the tray. The present invention can be applied to any disk drive device in the case of holding in the horizontal direction. Further, in the present invention, since the position of each holder can be set arbitrarily, even if a CD having a diameter other than 12 cm and 8 cm is provided, this can be handled.

[0015]

As described above, according to the present invention, a plurality of holders for holding a facing area of a peripheral portion of a disk are provided on a tray for setting a CD in a drive device body, and these holders are arranged in a radial direction of the disk. Since interlocking means for interlocking movement are provided, if the position of some of the holders is changed, the positions of the other holders are also changed in conjunction with this, so that when holding CDs of different diameters, Operation becomes easy. Further, as a configuration for interlocking each holder, a rod protruding from each holder to the opposite holder side and having a rack formed on a part thereof, and a pinion meshed with each rack between racks of each rod are provided. By adopting such a configuration, there is also an effect that the structure can be simplified.
