Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a magnetic disk drive as an external storage device such as a personal computer or a word processor for driving a flexible magnetic disk. And a support structure for the magnetic disk.

[Conventional technology]

Conventionally, as a support structure of a magnetic disk in a magnetic disk drive device, for example, a schematic diagram of a main part in FIG.
The configuration shown in the plan view of the magnetic disk shown is known,
This will be described.

As shown in the figure, the conventional magnetic disk drive 1 has:
As a support structure for the magnetic disk, support protrusions 3 are provided on both sides of the frame 2.

The support projections 3 are provided on the magnetic disk drive 1.
Is provided at a position for supporting both sides of the magnetic disk 4 inserted into the disk.

Further, the support position of the support protrusion 3 will be described in detail, as shown in FIG.

That is, as shown in FIG. 4, the magnetic disk 4
Each corner 5a, 5b, 5c, 5d of the case body 5 is supported by the support projection 3.

This is because the variation in the manufacturing of the magnetic disk 4 and the warping of the case body 5 due to the deformation of the magnetic disk 4 are absorbed without supporting the central portion, and the magnetic disk drive 1
This is to prevent the case body 4 of the magnetic disk 5 from coming into contact with the carriage 6 for transferring the magnetic head disposed in the above.

[Problems to be solved by the invention]

However, in the conventional magnetic disk drive 1 described above, the support protrusions 3 supporting the case 4 of the magnetic disk 5 are configured to support only both sides of the case 4 of the magnetic disk, and the magnetic disk 5 Since it is configured to absorb variations in warp and the like in the manufacture of the magnetic disk in the central space, a supporting height is required in consideration of the deformation of the magnetic disk 5, and as a result, the thickness of the magnetic disk drive 1 is reduced. There is a problem that it becomes difficult to deal with the problem.

In addition, since the middle portion of the case body 4 does not have a support portion, when the case body of the magnetic disk 5 bends and deforms at the middle portion, there is a problem that the middle portion of the case body 4 comes into contact with the carriage 6.

The present invention was devised in view of the above-mentioned problems,
It is an object of the present invention to provide a magnetic disk drive device in which a case body of a magnetic disk is supported at an intermediate portion to forcibly restrict deformation of the case body.

[Means for solving the problem]

Therefore, as means for solving the above-mentioned problem,
The present invention relates to a magnetic disk drive for driving a magnetic disk housed in a case body, wherein a magnetic disk support of the magnetic disk drive is provided with a first support provided at a position corresponding to a corner of the case body. And second support portions provided on both sides of the head carriage of the magnetic disk drive device and at positions corresponding to both sides of the opening provided on the back surface of the case body.

[Action]

With this configuration, the support position of the case body of the magnetic disk is forcibly regulated, and interference with the carriage is prevented.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a main part of the magnetic disk drive according to the present invention.

As shown, the magnetic disk drive according to the present invention
Reference numerals 10 denote first support projections on both sides of the frame 11 at positions corresponding to the corners 5a, 5b, 5c, 5d of the case body 5 in which the magnetic disks 4, 4 are housed. There are twelve.

Further, the frame 11 has a configuration in which second support protrusions 14 are provided on both sides of the carriage 13 at a portion 11a where the carriage 13 is located at an intermediate portion thereof.

That is, the second support projections 14 are located at positions corresponding to both sides 5e, 5f of the opening 5g provided in the case body 5 storing the magnetic disk 4 shown in FIG.

For this reason, the case body 5 of the magnetic disk 4 mounted on the magnetic disk drive 10 is positioned at the intermediate portion thereof by the second support projections 14, and the case body 5 is prevented from warping or deforming. It is mounted in a state corrected by the support projections 14.

[Effect of the invention]

Therefore, according to the magnetic disk drive of the present invention, the case body of the magnetic disk includes the first support provided on both sides of the frame and the second support provided in the middle of the frame. Deformation such as warpage or bending is regulated.

Since the case body is mounted while being regulated, the case body and the carriage of the magnetic disk drive are prevented from coming into contact with each other, and the mounting distance between the carriage and the magnetic disk case body can be made shorter than before. As a result, the magnetic disk drive can be made thinner.
