Abstract

PURPOSE:To prevent damage of a disk and maintain reliability of recording information by taking out the disk by a vacuum chuck or an electromagnetic chuck. CONSTITUTION:When a cartridge case 1 in which a disk 4 is accommodated is inserted into an outlet 9 of a driving device 5, an opening and closing mechanism 6 of the driving device 5 opens a cover 3 of the case 1. Then, a vacuum chuck 7 is moved and holds a flat section 11 of the disk 4. After the case 1 is returned to the outlet 9, an user takeout the case 1 from the outlet 9. Finally, the chuck 7 holds the disk 4 and is fitted into a spindle 8 for rotating the disk and a preparation for driving the disk is completed. A mounting of the cartridge 1 to the driving device 5, a taking out of the disk 4 and a return of the case 1 are all automatically performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc cartridge in which a disc such as an optical disc, a magnetic disc, a video disc, or a compact disc is housed in a cartridge case.

(Prior art) This type of disk cartridge protects the disk and
In addition, the disc is housed in a cartridge case so that the user can mount it in the disc drive device without touching the disc directly.

In order to drive a disc, there is a method in which the disc is housed in a cartridge case, is mounted on a disc drive device, and information is recorded or reproduced through a window provided in the cartridge case.

In other methods, the drive automatically pries open the cartridge case opening and mechanically hooks or grips the disk, extracting it from the cartridge case and driving it.

(Problems to be Solved by the Invention) In the method of driving the disc while it is housed in the cartridge case, the cartridge case does not remain in the hands of the user, and the data content of the disc written on the cartridge case cannot be viewed.

Furthermore, in the method in which the disc is removed from the cartridge case, the disc is mechanically hooked or grabbed using a claw or the like to be removed from the cartridge case, which can result in severe damage to that part of the disc and greatly reduce the durability of that part. However, there was a problem in that the structure of the disk became complicated.

The present invention attempts to solve these problems.

[Means for solving problems]

In order to solve the above problems, the disk cartridge of the present invention includes an opening formed to allow a vacuum chuck or an electromagnetic chuck of a disk drive device to be introduced into the cartridge case, and a hinge that covers the opening and opens and closes the opening. It is characterized by comprising a lid, and a substantially flat part provided on the disk and held by the vacuum chuck or a part made of a ferromagnetic material held by the electromagnetic chuck.

[Effect]

With the above structure, in the disk cartridge of the present invention, the disk can be held and taken out by a vacuum chuck or an electromagnetic chuck, so that the disk is not damaged when taking out the disk.

〔Example〕

FIG. 1 is a schematic sectional view showing a disk cartridge according to a first embodiment of the present invention.

An opening 10 is formed in the cartridge case 1 housing the disk 4 so that the vacuum chuck 7 of the disk drive device 5 can be introduced into the cartridge case 1. A lid 3 that can be opened and closed is attached. Note that a flat portion 11 is formed on the surface of the disk 4 so that the vacuum chuck 7 can hold the disk 4.

When the cartridge case 1 containing the disk 4 is inserted into the entrance/exit 9 of the disk drive device 5, the opening/closing mechanism 6 of the drive device 5 opens the lid 3 of the cartridge case 1, and then,
The vacuum chuck 7 moves and the flat part 1 of the disk 4
Hold 1. Next, the cartridge case 1 is inserted into the entrance/exit 9.
After being returned to , the user pulls out the cartridge case 1 from the entrance 9 of the drive device 5 . Finally, the vacuum chuck 7 holds the disk 4 and fits it into the spindle 8 for rotating the disk, completing preparations for driving the disk.

To install the disk cartridge 1 into the drive device 5, the user inserts the disk cartridge a little into the entrance/exit 9, moves the cartridge case 1 to a predetermined location in the device, and closes the lid 3 of the cartridge case 1. Opening/closing, ejection of disk 4 by vacuum chuck 7, and entrance/exit 9
The return of the cartridge case 1 up to this point is all done automatically.

FIG. 2 is a schematic sectional view showing a second embodiment of the invention. In the first embodiment shown in FIG. 1, the lid 3 constituting the entire top surface of the cartridge case 1 was designed to be opened, but in this embodiment, the lid 3 that partially opens the top surface of the cartridge case 1 is used. is the provision.

Next, third and fourth embodiments of the present invention will be described.

In these embodiments, the disk is held by an electromagnetic chuck of the drive device, and the lid of the cartridge case is fitted into the case.

FIG. 3(a) is a schematic sectional view showing a disk cartridge according to a third embodiment of the present invention, and FIG.
It is a partially enlarged view when the lid of a) is closed.

1. While the lid opening/closing mechanism of the drive device pushes the convex portion 12 provided at the end of the lid 3 in the direction of arrow A. Hook the recess 13 and move the arrow B.
Open in the direction.

The center jig 14 of the disk 4 is made of ferromagnetic material and can be held by an electromagnetic chuck.

FIG. 4(a) is a schematic sectional view showing a disk cartridge according to a fourth embodiment of the present invention, and FIG.
It is a partially enlarged view when the lid of a) is closed.

In this embodiment as well, the disk is held by the electromagnetic chuck of the drive device, and the lid of the cartridge case is fitted into the case; however, the lid 3 is provided on the side surface of the cartridge case 1.

The lid opening/closing mechanism of the drive device pushes the protrusion 12 provided at the end of the lid 3 in the direction of arrow A, and hooks the recess 13 to open it in the direction of arrow B.

The center jig 14 of the disk 4 is made of ferromagnetic material and can be held by an electromagnetic chuck.

a third holding the disc by the above electromagnetic chuck;
In the fourth embodiment, the entire center jig 14 is made of a ferromagnetic material, but only the surface of the center jig 14 may be made of a ferromagnetic material. A spacer (not shown) may be made of a ferromagnetic material and held by an electromagnetic chuck.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these embodiments and can be modified in various ways.

〔Effect of the invention〕

As explained above, the disk cartridge of the present invention has a structure in which the disk can be taken out by a vacuum chuck or an electromagnetic chuck, thereby preventing the disk from being damaged by the disk ejecting mechanism when loading and unloading the disk as in the conventional case. be able to. Therefore, the structure of the disk can be simplified because there is no need for a special structure to improve the reliability of recorded information and to increase the resistance of parts that were conventionally easily damaged.
