[Prior art]
2. Description of the Related Art In recent years, information processing apparatuses such as notebook personal computers have been improved in portability, such as being used outdoors, which has been reduced in weight, size, and thickness. In the information processing apparatus having such portability, the disk device described above is used as a storage device for storing information. Opportunities to attach and detach these storage devices from the information processing device as needed to expand the storage capacity or keep the stored information confidential. The removed storage device is carried by itself or stored separately.
[0003]
As a result, vibrations and shocks when being carried are applied to the storage device held inside the information processing apparatus via the information processing apparatus. Further, when the portable device is removed from the information processing device and carried, vibrations and impacts are directly applied to the disk device, so that a greater damage is caused. In order to avoid such a situation, a device has been devised to prevent damage to the disk device when it is held in or removed from the information processing apparatus.

[0014]
(Embodiment 1)
In the first embodiment, a hard disk device will be described as an example of a disk device according to the present invention.
[0015]

[0016]
1, 2, and 3, 1 is an impact resistant hard disk device, 2 is an upper case, 3 is a lower case, 5 is a tag, 6 is a signal cable, 7 and 8 are openings, and 9 is a hard disk device, 10a and 10b. 10c, 10d, 10e, and 10f are resin sheets, 11a, 11b, 11c, 11d, and 11e are creases, 12 are cut lines, 13a, 13b, 13c, 13d, 13e, and 13f are resin sheets 10a and 10b, respectively. It is an independent shock absorbing sheet affixed on the resin sheet 10c, the resin sheet 10d, the resin sheet 10e, and the resin sheet 10f.
[0017]
As shown in FIG. 1A, the hard disk device 9 according to the first embodiment is housed in aluminum cases 2 and 3, and the signal cable 6 connected to the information processing device and the shock-resistant hard disk device 1 are connected. A tag 5 for removal from the information processing apparatus is exposed from openings 7 and 8 provided in the cases 2 and 3. The hard disk device 9 is a flat rectangular parallelepiped, and includes a disk, a drive motor, a recording unit, a drive circuit, and the like, and is covered with a metal case. A gap between the hard disk device 9 and the cases 2 and 3 is filled with a cushioning material composed of the resin sheet 10 and the shock absorbing sheet 13 to protect the hard disk device 9 from impact. The outer dimensions of the hard disk device 9 are a height 7 mm, a width 70 mm, a length 100 mm, and the cases 2 and 3 are boxes made of an aluminum plate with t3 = 0.3 mm.
[0018]
The configuration of the cushioning material will be described with reference to FIGS. The resin sheet 10 of Embodiment 1 is a polyester film of t2 = 0.2 mm. The resin sheet 10 is provided with a fold line 11. When the resin sheet 10 is folded at an angle of 90 ° along the fold line 11, a rectangular parallelepiped larger than the hard disk device 9 is formed. A cut 12 is formed in the resin sheet 10, and a tag 5 that rotates with the crease 11 as a fulcrum when it is raised along the cut 12 is formed.
[0019]
Here, the shock absorbing sheet 13 used in the first embodiment will be described. The material is a commercially available urethane foam, a t1 = 3.5 mm sheet with a skin formed on the surface layer, and a flexible closed-cell polyurethane foam having a density of 0.06 g / cubic cm (closed cell ratio of about 70%). is there. When the bubble rate is 40% or less, when shock is received, the air in the bubbles is pushed out in a short time and the buffering capacity is lost. In the case of a self-foaming rate of 60 to 80%, it takes an appropriate time for the air in the bubbles to be extruded, and it also takes an appropriate time to return to the original state, so that the buffering capacity is large (Japanese Patent Laid-Open No. 6-136084). Etc.).
[0020]
The shock absorbing sheet 13 made of the above material is cut out in accordance with the pattern shown in FIG. 2 and is cut into six pieces and bonded onto the resin sheet 10. The shock absorbing sheets 13a and 13b are opposed to the upper and lower surfaces of the hard disk device 9, and the areas of the shock absorbing sheets 13a and 13 are the same as the areas of the upper and lower surfaces. In FIG. 3, the surfaces of the shock absorbing sheets 13a and 13b face the paper surface. The shock absorbing sheets 13c, 13d, 13e, and 13f are opposed to the side surface of the hard disk device 9, and are slightly larger than the area of the side surface, and in FIG. 3, each adhesive surface faces the direction of the paper surface. .
[0021]
As shown in FIG. 3, the resin sheet 10 and the impact absorbing sheet 13 are placed, and the bottom surface of the hard disk device 9 is overlaid on the resin sheet 10a. By raising the resin sheets 10b, 10c, 10d, 10e, and 10f along the fold line 11, the hard disk device 9 can be wrapped with a buffer sheet. When the package is packed in the lower case 3, the upper case 2 is covered from above, and the signal cable 6 and the tag 5 are pulled out from the openings 7 and 8, the impact resistant hard disk device 1 of FIG. 1 is completed.
[0022]
The dimensions of the hard disk device 9 are height H, width W, length L, the thickness of the shock absorbing sheet 13 is t1, the thickness of the resin sheet 10 is t2, and the thickness of the cases 2 and 3 is t3. The size of the shock absorbing sheets 13a and 13b and the resin sheets 10a and 10b is W × L, the size of the shock absorbing sheets 13c and 13e, and the resin sheets 10c and 10e are W × (H + 2 × t1 ), and the shock absorbing sheets 13d and 13f. The sizes of the resin sheets 10d and 10f are L × (H + 2 × t1 ). The internal dimensions of case 3 are (H + 2 × (t1 + t2)), (W + 2 × (t1 + t2)), and (L + 2 × (t1 + t2)).
[0023]
In FIG. 1, a sectional view in the direction of arrow A is shown in FIG. The top and bottom surfaces of the hard disk device 9 are in direct contact with the shock absorbing sheets 13a and 13b. On the other hand, the four side surfaces of the hard disk device 9 are in contact with the shock absorbing sheets 13c, 13d, 13e, and 13f through the resin sheets 10c, 10d, 10e, and 10f. The height of the shock absorbing sheets 13 c, 13 d, 13 e, and 13 f is thicker than the height of the side surface of the hard disk device 9 by two shock absorbing sheets 13. That is, the height of the hard disk device 9 is 7 mm, which is twice as large as 14 mm.
[0024]
In general, the disk device is a flat rectangular parallelepiped, and the cross-sectional area of the side surface is smaller than the cross-sectional areas of the top surface and the bottom surface. Accordingly, the buffering effect is reduced with respect to impacts in the left and right and front and rear directions. In Embodiment 1, a polyester film of t2 = 0.2 mm was used as the resin sheet 10. Since the resin sheet 10 has sufficient rigidity with respect to instantaneous force, the shock absorbing sheet 13 at the height H part cushions the shock and the shock absorbing sheet 13 is bonded to the opposite surface, such as the top and bottom surfaces. The cross-sectional area is twice that of the case. When the side surface of the hard disk device 9 is in direct contact with the shock absorbing sheet 13, even if the height of the shock absorbing sheet 13 is (H + 2 × t1), only the substantial H equivalent supports the shock. . When t2 is less than 0.1 mm, the waist is weak and the effect of expanding the shock absorption cross section is reduced.
[0025]
FIG. 5 is a perspective view showing a state in which the impact-resistant hard disk device 1 according to the first embodiment is attached to the information processing device 20. The impact resistant hard disk device 1 is supported by the storage frame 22. When the lid 21 is opened, the tag 5 is folded on the upper surface. When the connecting cable 6 is pulled out from the connector and the tag 5 is pulled upward, the shock-resistant hard disk device 1 can be removed. The removed impact-resistant hard disk device 1 is small and lightweight and can be put in a pocket. In addition, since it has sufficient impact resistance, the stored information is not destroyed even if it is carried around naked.
[0026]
When the upper case 2 is opened and the resin sheet 10b is pulled out, the hard disk device 9 can be removed while being wrapped in the resin sheet 10. In the conventional apparatus in which the resin sheet 10b is not provided, the connection cable 6 may be pulled out, which may cause damage to the connection cable 6.
[0027]
Moreover, polycarbonate, vinyl chloride, etc. can be used as the resin sheet.
[0028]
Moreover, a polyethylene foam etc. can be used as a foam.
[0029]
In the first embodiment, substantially equal to the total thickness of equal Oite the average distance is six directions from the outer peripheral surface of the disk device to the outer casing peripheral surface, and said average distance (resin sheet + impact-absorbing sheet) However, when the disk device has directionality with respect to impact, the thickness of the impact absorbing sheet may be set corresponding to the directionality.
[0030]
Moreover, the thickness of the buffer means can be reduced by making the total thickness of (resin sheet + impact absorbing sheet) larger than the gap between the outer peripheral surface of the disk device and the inner peripheral surface of the outer case. Moreover, when using a hydrophobic urethane foam, airtightness can be improved and moisture permeability can be improved by compressing and filling a urethane foam.
[0031]
【The invention's effect】
