Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disk automatic shark II 'fs m, and more particularly to a disk drive loading mechanism with a simple structure that is intended for IQ disks. By the way, here's a disclaimer.

2.2 shall refer to video discs, audio POM discs, and professional digital optical discs.

Conventionally, the disk automatic device K mechanism has a car cell, that is, a donut-shaped storage tube that stores the disk, but the size is large, it takes a long time to access, and the car cell rotates. There are many departments that consume a lot of power. In particular, 1. As mentioned above, a more economical mechanism is desirable for a moving table that is intended for about 10 disks.

The present invention has been made in view of the above circumstances, and its objectives are to eliminate the above-mentioned 1 unit of conventional disk automatic loading mechanism, to simplify the mechanism, to reduce the size of the device, and to provide easy access. To provide an automatic disk mounting MTM structure that takes less time and consumes less power.

The above-mentioned object of the present invention is to provide storage means for storing a plurality of discs or disc cartridges, a disc drive device for recording and reproducing information on the disc, and a disc drive device for storing a plurality of discs or disc cartridges; In automatic disk loading W4N of a disk device having a disk moving mechanism for taking out or storing a disk or a disk cartridge from the ore collecting means, loading and unloading the disk in the disk drive 1, and a control section for controlling each of the above-mentioned operations. ,
It is connected by an automatic disk loading structure characterized by a previously provided disk or disk cartridge transport means.

Hereinafter, the details will be explained based on the drawings of the embodiments of the present invention.
A.

In addition, there are two ways to store the hot spring cure, one in which the disk is placed in a cartridge, and another in which the disk is stored without putting it in a cartridge, so to speak.
In the following explanation, an example will be explained in which a disk is placed in a cartridge for storage.

FIG. 1 is a plan view of an automatic disk loading mechanism according to an embodiment of the present invention, and FIG. 2 is a front view thereof.

In the figure, 1 is a disk drive device, 6 is a cartridge moving mechanism, and 7 is a cartridge storage tube.

First, the operation from taking out the disk to loading it into the disk drive device 1 will be explained.

When the control section receives a command to select a predetermined disk from the host device, the cartridge moving mechanism 6 is rotated by the motor 6 in the direction of arrow a or a'.

position. To detect the position of the disc, for example, a bar hood 11 having a hood formed from the base is attached to the cartridge storage box 7, and the bar hood 11 is read out.

When the cartridge moving mechanism 6 is positioned at a predetermined position, the cartridge holder 8 in the cartridge moving mechanism δ moves into the cartridge storage box 7 and clamps the cartridge 9't. The mechanism for moving the cartridge holder 8t and the mechanism for clamping the cartridge 9 will be described in more detail with reference to FIGS. 311 and 4.

3 is a view of the car cartridge moving mechanism δ viewed from the direction of the arrow X in FIG. 2, and FIG. 4 is a sectional view taken along the Y-Y' direction of FIG. In FIG. 3, the cartridge guide 8 is transported in the direction indicated by the arrow by a rack and pinion mechanism driven by a motor (not shown). Since the cartridge holder 8 is guided by the holder guide 15,
The direction guided by the guide 15 (FIl arrow by
It is possible to move only in the direction indicated by height b'.

On the other hand, the cartridge 9 is positioned by a rail-shaped guide 7 & located on the lower side of the cartridge storage box 7. Then, the cartridge holder 8 is guided by a guide 7b located on the upper side of the cartridge storage box 7 and moves to a predetermined position (see FIG. 2).
“The cartridge 9 is caught by the clamping latch 16 provided on the cartridge holder 8.

Recesses 9m and 9'b are provided, and the rack 16 clamps the cartridge 9 by a wire 18 linked to a latch motor 17 (see FIG. 4).

When the clamping of the cartridge 9 is completed, the rack/binion 5III (not shown) is operated in the avoidance direction as before, and the cartridge holder 8 with the cartridge 9Yt clamped is transferred in the direction of the arrow b'. Force - When the cartridge holder 8 returns to the cartridge moving mechanism, the cartridge holder 8 is in a position on the extension of the cartridge guide 3 so that the loading path to the cartridge guide 3 in the disk drive 1 is straight. The cartridge moving mechanism 6 rotates in the direction of arrow a or 1'. Further, if recording and reproduction are possible on both sides of the disc and it is necessary to reverse the disc, at this stage the cartridge moving mechanism 6 is rotated 180 degrees in the direction of arrow a or a'.

move.

When the rotation of the cartridge moving mechanism 6 is completed and the cartridge and the joint holder 8 are positioned on the extension line of the cartridge guide 3, the cartridge 8 with the cartridge 9 clamped by the rack and binion mechanism is transferred in the direction of the disk drive device l. Then, the cartridge 9 is inserted into the cartridge guide 3.

When the cartridge 9 is completely inserted into the cartridge guide 3, the latch motor 17 rotates in the opposite direction to release the clamp on the cartridge 9. After the clamp is released, the cartridge holder 4 operates to press the cartridge 9 toward the hub 2. As a result, the disk 10 in the cartridge 9 is moved by the disk drive motor 19.
The disk 1o can be rotated by being clamped to the hub 2 which is directly connected to the disk 1o.

FIG. 6 shows details of the clamping mechanism for the disk IO.

In the figure, 21 is a disk clamp, and 22 is a spring, and the cartridge guide 3 is pressed by the cartridge retainer via the spring 22 to the stopper 20. on the other hand,.

This is because the disk 10 is loaded into the chamber 2 before the cartridge guide 3 hits the stopper 20.

The disc 10 becomes floating inside the cart seeker 9,
It will be able to rotate freely. At this time, since the rotatable disk clamp 21 presses the disk 10 against the hub 2, the disk 10 is completely clamped to the hub 2. Further, while the disk 1o is clamped to the hub 2, the cartridge guide 3 is also clamped by a latch (not shown).

When the disk drive device 1 finishes recording and reproducing the disk 10, and the disk 1o is removed from the disk drive 2 and stored in the cartridge storage box 7, the above is performed.

This will be done by following the steps described above in reverse.

FIG. 6 shows an embodiment of the cartridge holder. Since the cartridge 9t is supported at the lower part of the cartridge holder 8', stability during movement of the cartridge 9 is improved. Limited to this.

Needless to say, the transfer mechanism and the drive mechanism can be formed by applying existing atomic technology. For example, the wire drive (clamp mechanism in Figure 4) is by a link mechanism or a motor.

It is possible to replace it with a direct drive.

Further, in the above embodiment, the case where there is only one disk drive device is shown, but the number of disk drive devices is not limited to one, but it is also possible to use a plurality of disk drives.

In this case, the access time, - the rotating di-suf [
The time it takes to stop the disk, remove the disk from the disk drive, load another disk, start rotating, and reach a steady rotation speed, or improve the reliability of the entire system. The effect Yt can be obtained.・To explain this in detail, when there are ・11 disk drives, the access time is approximately 10
For example, if two disk drives are provided, one disk drive can load another disk into the other non-operating disk drive while one disk drive is in operation. Access time is essentially -.

It can be considered as zero. Di.

It goes without saying that the system can be prevented from going down due to its flexibility in the event of a failure of the SF drive device.

Cartridge storage box with cartridge moving mechanism.

In addition to the above-mentioned bar code detection method, the positioning of the motor 7 with respect to each storage section may be performed by controlling the motor 6 as a step motor.

Further, in the above embodiment, an example was shown in which all the disks are stored in the car 4 storage t7 and handled, but it goes without saying that by changing the shape of the holder, etc., it is possible to directly handle the disks.

As described above, according to the present invention, the means for storing a disk or a disk cartridge is a fan-shaped rigid storage section, and the disk disposed between the storage section and the disk drive device is rotatable. The mechanism is simple, access time is short, and the slideable disk or disk cartridge transfer means is mounted on a base.
This has the remarkable effect of realizing a compact automatic disk loading mechanism that consumes less power and is suitable for cases where the number of disks is less than 10.
