Abstract

PROBLEM TO BE SOLVED: To secure a proper operating condition of a hard disk by making the mounting section of a mounting member displaceable against a mounting surface, to absorb dimensional tolerances of the disk and the mounting section, and properly mounting the disk on the member to avoid an unnecessary external force applied to the disk from the member. SOLUTION: A hard disk 22 is inserted into the opening of the right side of a mounting member 9 and mounted to the member 9 by the screws which connect the top surface of the disk 22 to a top side mounting section 15 of a top section wall 10 and the bottom surface of the disk 22 to a bottom side mounting section 16 of a bottom section wall 11. While mounting the disk 22 to the member 9, the dimensional tolerance of the disk 22 or the member 9 is absorbed because the section 15 formed on the wall 10 is formed in a tongue shape and the disk 22 is mounted on the member 9 without an unnecessary external force that may be exerted on the disk 22 by the member 9.

As described above, when the mounting member 9 is inserted into the arrangement portion 8, the two are connected to each other so that the power supply unit of the main body 2 and the hard disk 22 are electrically connected.

In the state where the mounting member 9 is mounted on the disposing portion 8 of the main body 2 as described above, the drive of the hard disk 22, that is, the rotation of the disk disposed inside the hard disk 22 and the rotation of the head are performed. Access or the like is performed, and recording or reproduction of digital data such as video and audio is performed.

As described above, by forming the tongue-shaped upper mounting portions 15 of the mounting member 9, the hard disk 22 is mounted on the disposing portion 8 without unnecessary external force from the mounting member 9. The hard disk 22
Vibration hardly occurs when this is driven, and the hard disk 2
2 can ensure the proper operation state.

In the mounting member 9, since the bent portions 10b and 11a are formed on the left edges of the upper wall 10 and the lower wall 11, which are the mounting surfaces for mounting the hard disk 22, the upper wall 10 and the lower The rigidity of the wall 11 is high,
The bending rigidity is high so that the upper wall 10 and the lower wall 11 are not easily formed into a vertical cross-sectional shape and have a downward or upward convex shape. Accordingly, vibration is less likely to occur when the hard disk 22 is driven, and an appropriate operating state of the hard disk 22 can be secured.

Further, in the mounting member 9, the base end edges of the upper mounting portions 15, 15 and the lower mounting portions 16, 16 have step portions 15a, 15a,... Or step portions 16a, 16a,
Are formed in the shape of a step extending in the left-right direction, so that the steps 15a, 15a,.
6a, the bending rigidity is increased so that the upper wall 10 and the lower wall 11 are hardly formed into a downward or upward convex shape in a cross-sectional shape. Therefore, vibration is less likely to occur when the hard disk 22 is driven, and a more appropriate operating state of the hard disk 22 can be ensured.

In addition, the upper wall 10 of the mounting member 9 has a narrowed portion 10 extending in the front-rear direction at a position on the right side of the mounting member 9.
a is formed on the right side of the upper wall 10 and the rigidity of the bent portion 10b is hardly increased by the bent portion 10b as compared with the left portion.
By forming a, the rigidity of this rightward portion of the upper wall 10 is increased. Therefore, even when the aperture portion 10a is formed, vibration is less likely to occur when the hard disk 22 is driven, and an appropriate operation state of the hard disk 22 can be ensured.

By forming the tongue-shaped upper mounting portions 15, 15 formed on the upper wall 10, the rigidity of the upper wall 10 is slightly reduced as compared with the case where the upper mounting portions 15, 15 are not formed. The portion 10a is slightly longer than the interval between the screwing portions 15b, 15b, and is formed so that both front and rear ends are located in front of the front screwing portion 15b or behind the rear screwing portion 15b. Therefore, a decrease in rigidity of the portion where the upper mounting portions 15 are formed is prevented.

The mounting members 9, 9,... Have a plate thickness of 1.2 mm, which is greater than the conventional mounting member having a plate thickness of 1.0 mm. As a result, the overall rigidity is increased as compared with the conventional mounting member.

In the above description, the mounting member 9 in which the throttle portion 10a is formed only on the upper wall 10 is shown. However, the present invention is not limited to this, and the throttle portion is formed on the lower wall 11 in order to further increase the rigidity of the mounting member 9. And the front wall 12, the rear wall 1
3. The rigidity of the mounting member 9 can be further increased by forming it on the side wall 14.

Also, the bent portion is formed on another portion of the mounting member 9, for example, on the right edge of the upper wall 10 or the lower wall 11 in order to increase the rigidity of the mounting member 9. Rigidity can also be increased.

[0055]

As is apparent from the above description, the mounting structure of the hard disk of the present invention is such that the mounting surfaces facing the opposite sides of the hard disk in the state of being housed inside the mounting member have respective mounting surfaces of the mounting member. A mounting structure of a hard disk attached to a mounting portion formed on the surface,
Since the mounting portion formed on one mounting surface is in the shape of a tongue, the hard disk is mounted on the mounting member without unnecessary external force from the mounting member, and vibration hardly occurs when driving the hard disk, Can maintain an appropriate operation state.

According to the second aspect of the present invention, since the bent portion is formed on at least one side edge of the mounting surface of the mounting member, the rigidity of the mounting surface is increased, and further vibration occurs when the hard disk is driven. It is difficult to secure an appropriate operation state of the hard disk.

According to the third aspect of the present invention, the base edge continuous with the mounting surface of the mounting portion is formed such that portions other than the base edge of the mounting portion are substantially parallel to the mounting surface on the hard disk side of the mounting surface. It is formed as a step so as to be located, and the step is extended in the direction perpendicular to the direction in which the bent part extends, so the rigidity of the mounting surface is further increased, and vibration is less likely to occur when driving the hard disk Thus, the proper operation state of the hard disk can be further ensured.

Another mounting structure for a hard disk according to the present invention is a hard disk mounting structure in which a hard disk is mounted on a mounting member in a state where the hard disk is housed in a mounting member having at least one opening. Since the side edge opposite to the edge is bent to form a bent portion, and a punched narrow portion formed in the opening edge side in the same direction as the bent portion extends, the rigidity of the mounting member is increased, and the hard disk is hardened. Vibration is less likely to occur at the time of driving, and a proper operating state of the hard disk can be ensured.

According to the fifth aspect of the present invention, a tongue-shaped mounting portion for mounting a hard disk is formed by punching a part of the mounting member so as to be spaced apart in the extending direction of the narrowing portion. Since the portion is formed to be equal to or longer than the interval between the mounting portions, the rigidity of the mounting member due to the formation of the mounting portion is prevented, the vibration is less likely to occur when the hard disk is driven, and the hard disk Can secure a more appropriate operation state.

It should be noted that the specific shapes and structures of the respective parts shown in the above-described embodiment are merely examples of the embodiment when practicing the present invention.
These should not be construed as limiting the technical scope of the present invention.
