Thus, the loading state is attained, the optical disk 2 is driven, the pickup 10 is moved along the guide rail 11 in the radial direction of the optical disk 2 to record or reproduce the optical disk 2.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a disk drive device that records and/or reproduces information by rotationally driving an information recording medium formed in a disk shape, and particularly relates to an optical recording medium. The present invention relates to a disk drive suitable for media.

[Conventional technology]

Optical disk drive devices usually employ an autoloading mechanism for recording and reproducing information by introducing an information recording medium (hereinafter referred to as a disk) placed on a tray into the device together with the tray. Conventional examples of such optical disk drive devices are shown in FIGS. 4 and 5.

FIG. 4 is a sectional view showing an unloaded state in which the tray of a conventional optical disk drive device advances from the device main body side, and FIG. 5 is a sectional view showing a loaded state in which the tray is housed in the device main body. .

First, in FIG. 4, the optical disk drive device 1 includes a tray 3 that stores a disk 2 via a sub-tray 4, which will be described later, and can move in and out of the device horizontally, and a drive means (not shown) that moves the tray 3 in and out of the device. ), a sub-tray 4 capable of moving the optical disc 2 81 and 1 Z downward within the tray 3, a lowering means (not shown) for the sub-tray 4, and a convex portion 5 inserted into the central circular hole of the disc 2. A turntable 6 that rotationally drives the disk 2, a motor 7 that rotationally drives the turntable 6, a clamper 8 that presses the vicinity of the central circular hole of the optical disk 2 against the turntable 6, an arm 9 that rotates the clamper 8 up and down, A pickup 10 that performs recording and reproduction of the optical disc 2, a guide rail 11 that guides the pickup 10 in the radial direction of the optical disc 2, and the pickup 10.
A linear motor (
(not shown).

Such an optical disk drive device 1 operates as follows.

First, as shown in FIG. 4, the optical disc 2 is placed in an unloaded state on the sub-tray 4'' in the tray 3. Next, the tray 3 is drawn into the apparatus 1 by a drive means (not shown), and when this drawing is completed, the sub-tray 4 is lowered toward the turntable 6 side. During the lowering process of the sub-tray 4, the optical disc 2 is left on the turntable 6h, and the sub-tray 4 finishes lowering at a position a little distance away from the optical disc 2. Furthermore, while the rotary tray 4 is being lowered, the clamper 8 is also lowered and presses the optical disc 2 against the turntable 6.

In this way, the loading state shown in FIG. 5 is reached, and the optical disc 2
rotates, and the pickup 10 is moved in the radial direction of the optical disc 2 along the guide rail 11 by a linear motor (not shown), thereby recording or reproducing information on the optical disc 2.

When recording or reproduction of the optical disc 2 is completed, the clamper 8 rises, and the sub-tray 4 also rises, releasing the optical disc 2 from the turntable 6, causing the tray 2 to protrude, and returning to the unloaded state shown in FIG. 4. The optical disc 2 can be removed.

[Problem that the invention seeks to solve]

Incidentally, in the optical disk drive device configured as described above, it is necessary to move the sub-tray 4 and the clamper 8 up and down, and each is provided with a drive mechanism for this purpose. In particular, it is necessary to avoid the sub-tray 4, the turntable 6 and the pickup 10, and to place the optical disc 2 stably.Furthermore, it is necessary to store the elevating means in the tray 2, which requires a complicated mechanism. Become. Also, clamper 8
Since it is lowered -L by the rotating arm 9, its stroke and occupied volume are large, and it has a complicated vertical movement mechanism at its base.

In this way, the subtray 4 and the clamper 8 not only complicate the mechanism of the optical disk drive device, but also become a factor that hinders the reduction in thickness. For example, this thinning of a personal computer with a built-in floppy disk device
This is required to make it possible to replace one floppy disk device with an optical disk device.

The present invention has been made in view of the problems of the prior art described above, and an object thereof is to provide a disk drive device that can promote thinning.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a tray on which a disk is placed horizontally and can be horizontally moved in and out of the apparatus, a drive means for moving the tray in and out of the apparatus, The disk drive apparatus includes a turntable for rotationally driving a disk, and includes loading means for moving the turntable substantially perpendicularly to a tray and loading the disk onto the turntable.

[Effect]

With the above configuration, the disc placed on the tray is introduced into the device along with this tray, and the turntable is vertically raised to load the disc, thereby creating a mechanism for lowering the sub-tray within the tray and a mechanism for lowering the disc. It becomes possible to load the disc even without a mechanism for lowering the clamper from the second position.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

1 to 3 are for explaining the present invention in detail. FIG. 1 is a sectional view showing the loaded state of the optical disk drive device with the tray stored, and FIG. 2 is a sectional view showing the loaded state with the tray stored. FIG. 3 is a sectional view showing a state in which the tray is in an unloaded state with the tray protruding.

In the following description, components that are the same as or can be considered to be the same as those of the conventional example are given the same reference numerals.

The explanation will first be about the overall structure and operation, and then the mechanism for raising and lowering a small frame equipped with a turntable and the like.

First, in FIG. 1, an optical disk drive device 1 stores an optical disk 2 and moves horizontally into and out of the device.

The tray 3 is flexible and does not have the subtray shown in the conventional example, and the drive means (for moving the tray 3 in and out of the device)
(not shown), a turntable 6 that includes a convex portion 5 inserted into the central circular hole of the optical disc 2 and rotates the optical disc 2
, a motor 7 that rotationally drives the turntable 6, a clamper 8 that presses the vicinity of the central circular hole of the optical disc 2 on the turntable 6, a pickup 10 that performs recording and reproduction of the optical disc 2, and a guide that guides the pickup 10 in the radial direction of the optical disc 2. It mainly consists of a rail 11, a linear motor (not shown) that moves the pickup 10 along the guide rail 11, and small frames J and 12 that move the motor 7 and the pickup 10 up and down integrally.

Such an optical disc drive bag M1 operates as follows. As shown in FIG. 1, the optical disc 2 is placed on the tray 3- in an unloaded state. The l-ray 3 is drawn into the device 1 by drive means (not shown). When this retraction is completed (FIG. 2), the small frame 12 rises approximately perpendicularly to the retracted tray 3, and this small frame 1
A turntable 6 provided on the optical disc 2 further raises the optical disc 2. Then, the optical disc 2 is pressed against the clamper 8 while keeping a slight distance from the tray 3. Along with this, the pickup 10 provided in the small frame 12
also approaches the optical disc 2.

In this way, the loading state shown in FIG. 3 is reached, and the optical disc 2
is rotated, and the pickup 10 is moved in the radial direction of the optical disc 2 along the guide rail 11 by a linear motor (not shown), thereby recording or reproducing the optical disc 2.

When the recording or reproduction of the optical disk 2 is completed, the small frame 12 descends substantially perpendicularly to the tray 3, and the optical disk 2 is separated from the clamper 8 and placed on the tray 3, so that the turntable 6 does not interfere with the movement of the tray 3. Stop descending at the height (Figure 2). Then, the tray 2 is pushed out to reach the unloaded state shown in FIG.
can be removed.

〔Effect of the invention〕

As explained above, in the present invention, a disc placed on a tray is introduced into an apparatus together with this tray, and the turntable is raised perpendicularly to the tray to load the disc. This eliminates the need for a mechanism for lowering the clamper or a mechanism for lowering the clamper from above the disk, which has the effect of making the disk drive device thinner and easier to use.
