2. Description of the Related Art In recent years, information processing devices such as notebook computers have been reduced in weight, size, and thickness, and have been improved in portability such as being used outdoors. In such an information processing device having portability, a hard disk drive is used as a storage device for storing information. In order to expand the storage capacity or maintain the confidentiality of stored information, such storage devices are frequently attached to and detached from the information processing device. Further, the removed storage device can be carried by itself or stored separately.

As a result, when the information processing device is carried, the storage device held in the information processing device is damaged by shock or vibration applied via the information processing device. Further, the storage device carried by itself is subjected to a shock or vibration directly, unlike the case where the storage device is held in the information processing device, so that the storage device is further damaged. Further, even a storage device in storage is often damaged by unexpected shock or vibration depending on the environment of the storage location.

In order to avoid such a situation, various measures have been taken to prevent the storage device from being damaged by suppressing the shock and vibration exerted on the storage device, whether it is held or not held in the information processing device. There is.

A conventional shock absorbing holder and an information processing apparatus using the same will be described below with reference to FIGS. 23, 24, and 25.

FIG. 23 shows an information processing apparatus incorporating a storage device held by a conventional shock absorbing holder. In addition, in FIG.
It shows a state in which the opening / closing lid L of the storage device storage portion 1c of Pp is opened. In the information processing device DPp, a keyboard 4 is arranged in an approximately upper half portion of the housing 1, and a storage portion 1c for a component such as a storage device that needs to be attached and detached is provided in a lower half portion. The storage unit 1c stores the main circuit board 2 and a storage device unit SU in which a hard disk drive is held by a shock absorbing holder. The storage device unit SU is connected to the main circuit board 2 by a signal cable 6. An opening / closing lid L is attached to the upper surface of the storage section 1c. Further, a display unit 5 is attached to the upper end of the housing 1 so as to be openable and closable.

FIG. 24 shows the structure of the storage device unit SU. The storage device unit SU includes a hard disk drive 3, a shock absorbing holder 51, and a cover 52. The shock absorbing holder 51 is formed of a material having low hardness and low resilience into a box-like container shape having a recess 51c having a shape matching the shape of the hard disk drive 3. The cover 52 is formed of the same material as the shock absorbing holder 51 into a flat plate shape.

The storage device unit SU is constructed by housing the hard disk drive 3 in the recess 51c of the shock absorbing holder 51, and pressing the hard disk drive 3 by fitting the cover 52 into the recess 51c from above. As described above, the signal cable 6 of the hard disk drive 3 is made to extend outside the storage device unit SU from between the shock absorbing holder 51 and the cover 52 so that it can be connected to the main circuit board 2.

FIG. 25 shows a state of the storage device unit SU when the information processing device DPp receives an impact from the side surface direction. An arrow Fa is displayed on the housing 1 of the information processing device DPp.
When a shock is applied from the direction of, the hard disk drive 3
Causes a force to move in the Fr direction which is the opposite of the Fa direction. However, the shock absorbing holder 51 and the cover 5
Since 2 is made of a material having low hardness and low repulsion, the hard disk drive 3 of the shock absorbing holder 51 moves as the hard disk drive 3 moves in the Fr direction.
Is deformed to absorb the impact force acting on the hard disk drive 3. Due to such deformation, damage to the hard disk drive 3 due to impact is prevented.

When the hard disk drive 3 is removed from the housing 1 for carrying out capacity expansion or security protection and is carried or stored, the hard disk drive 3 is provided from the shock absorbing holder 51 and the cover 52, not as the storage unit SU. Take out and handle alone.

[0011]

As described above, as described above,
In order to enhance the shock absorbing effect in the information processing apparatus, a gel-like low hardness and low repulsion material is adopted for the shock absorbing holder 51. However, since the gel-like material has low resilience and low hardness, the shock absorbing holder 51 formed in the shape of a box is not self-supporting. In other words, without the aid of some other auxiliary means, the shock absorbing holder 51
Can't keep its box shape. Therefore, before installing the hard disk drive 3 in the housing 1, when installing the shock absorbing holder 51 in the housing portion 1c of the housing 1,
The shock absorbing holder 51 loses its shape.

As described above, when the shock absorbing holder 51 is not self-supporting and is deformed, it is very difficult to assemble the memory device unit SU. In addition, the storage device unit S
Since the shock absorbing holder 51 is deformed during the assembling of U, stable shock absorbing performance and holding performance cannot be secured even in the storage device unit SU that can be assembled somehow.

Conventionally, the following three methods have been adopted as measures against these problems. The first method is to increase the hardness of the material of the shock absorbing holder 51 and prevent it from losing its shape. In the second method, the thickness of the material of the shock absorbing holder 51 is increased more than necessary to ensure the self-supporting property. In the third method, for example, the hard disk drive 3 that accommodates the concave portion 51c of the shock absorbing holder 51 is made slightly larger so that the hard disk drive 3 can be accommodated even if the shock absorbing holder 51 is deformed.

However, as in the first method and the third method, if the hardness of the material of the shock absorbing holder 51 is increased or the recess 51c is made larger than the hard disk drive 3 by one size, the housing 1 is shocked. When receiving the shock, the shock absorbing holder 51 cannot sufficiently receive the hard disk drive 3, and the hard disk drive 3 cannot be sufficiently protected from shock. Also in the second method,
If the thickness of the shock absorbing holder 51 is increased more than necessary,
As will be described later, it goes against the demand for lighter, smaller, and thinner information processing devices.

Further, when a gel material having a high impact absorbing capacity is used as the impact absorbing holder 51, there are the following problems. That is, since the gel material has a high viscosity, the shock absorbing holder 51 adheres to the housing 1,
It is difficult to attach / detach the storage device unit SU to / from the housing 1.
The gel material has low heat conductivity, and it is difficult to dissipate heat generated from the hard disk drive 3. As a result, the held hard disk drive 3 is likely to overheat.

Further, in recent years, in order to improve the portability of the information processing apparatus, the size and thickness of the information processing apparatus have been further reduced. Therefore, it is essential to reduce the thickness of the shock absorbing holder. Similarly, the hard disk drive is also thinned, and has a so-called flat shape. As described above, in the storage device unit SU in which the flattened hard disk drive 3 is housed in the thinned shock absorbing holder 51, the hard disk drive 3
A case where an impact is applied to the side surface 3a in the Fa direction will be described below with reference to FIG.

The impact force is concentrated on a narrow area of the side surface 3a of the thinned hard disk drive 3. That is, the impact force that acts on the hard disk drive 3 in the Fr direction is applied to the hard disk drive 3 by the shock absorbing holder 51.
Must be received and absorbed by the narrow side surface 3a. Therefore, in such a thinned hard disk drive 3, the impact force per unit area of the side surface 3a is several times that of the storage device unit SU incorporating the non-thinned hard disk drive 3. Nevertheless, the amount of the impact absorbing holder 51 that can be used for absorbing impact force is a fraction. as a result,
The hard disk drive 3 bites into the shock absorbing holder 51, and the shock absorbing effect of the shock absorbing holder 51 is reduced.

Furthermore, when a material having a low hardness and a low coefficient of restitution represented by a gel material is used for the shock absorbing holder 51, the shock absorbing holder 51 is worst in the worst case when the wall thickness is thin. The movement of the hard disk drive 3 cannot be absorbed. Then, the side surface 3 of the hard disk drive 3
The a hits the housing 1 and other structural parts through the shock absorbing holder 51. In such a case, it goes without saying that the hard disk drive 3 suffers a great deal of damage.

On the other hand, the impact force parallel to the bottom surface of the storage device unit SU, that is, the impact force perpendicular to the bottom surface of the recess 51c or the bottom surface or top surface of the cover 52 is applied to the recess 5.
When acting on the central portion of the bottom surface of 1c, the impact force is evenly received on the bottom surface of the recess 51c or the vast area of the lower surface of the cover 52. As a result, the impact force is absorbed by the large amount of impact absorbing holder 51, and the hard disk drive 3 is not damaged as in the case described above.

However, an impact force that is non-parallel to the bottom surface of the storage device unit SU, that is, an impact force that is oblique to the bottom surface of the recess 51c or the bottom surface of the cover 52, is
In particular, when the hard disk drive 3 works near the end of the bottom surface of the recess 51c, the hard disk drive 3 tries to move in an oblique Fs direction with respect to the bottom surface of the recess 51c or the side wall of the housing 1. In this case, the impact force is the side surface 3 of the hard disk drive 3.
Concentrate on edge part C, which is much narrower than a. As a result,
The edge portion C of the hard disk drive 3 easily bites into the shock absorbing holder 51 and hits the housing 1. Also,
In the worst case, the edge portion C of the hard disk drive 3 destroys the shock absorbing holder 51 and further directly hits the housing 1 to severely damage the hard disk drive 3 itself.

As described above, when it is intended to obtain a high shock absorbing effect by using a material having a low hardness and a low coefficient of restitution for the shock absorbing holder 51, convenience of assembling the information processing apparatus, downsizing, And the heat dissipation is significantly impaired. Further, from the viewpoint of maintenance and security, when the hard disk drive 3 is removed from the information processing device DPp and managed independently, in the conventional configuration, the hard disk drive 3 is once removed from the shock absorbing holder and is in an unprotected state. Becomes For this reason, in such an unprotected state, the hard disk drive 3 is inadvertently impacted by being dropped or the like, and the hard disk drive 3 is often damaged.

When the hard disk drive 3 is detached and handled alone, the signal cable 6 drawn out from the hard disk drive is cumbersome to handle, and there is a problem such as disconnection, so the hard disk drive 3 must be handled with caution. . Further, even when the hard disk drive 3 is housed in the information processing device DPp again, it is difficult to assemble the storage device unit SU.

The present invention solves the above-mentioned problems, and is a shock absorbing holder that is mounted on a shock-sensitive device such as a hard disk drive to protect the shock-sensitive device from shock or vibration. Therefore, it is an object of the present invention to provide an impact absorbing holder having a thin material and a small thickness. Furthermore, it can be easily mounted on such a shock-sensitive device, adheres closely to the mounted shock-sensitive device to ensure stable shock absorption performance, and should be handled as a stand-alone condition with the shock-sensitive device removed from the information processing device. It is an object of the present invention to provide a shock absorbing holder capable of It is another object of the present invention to provide a shock absorbing unit configured by mounting such a shock absorbing holder on a shock sensitive device, and a small and lightweight information processing device including the shock absorbing unit.

As a result of the configuration as described above, the shock absorbing holder SAH has a rectangular annular shape having a generally U-shaped cross-sectional shape, as typically shown in the cross-sectional views of FIGS. 2 and 3. It has a space CS surrounded by an outer wall inside. The internal space CS is a rectangular space defined by a height H1, a width L1, and a length L2. In addition, this rectangular space CS
In addition, since the shock-sensitive device to be protected from a shock is housed and held, this rectangular space CS is called a housing space CS in this sense. Hereinafter, with reference to FIGS. 4, 5, 6 and 7, a method of housing the shock sensitive device in the housing space CS of the shock absorbing holder SAH will be described in detail.

First, a hard disk drive 3 will be described with reference to FIG. 4 as an example of a shock sensitive device for holding the shock absorbing holder SAH in the accommodation space CS according to this embodiment. The hard disk drive 3 is the same as that stored in the storage device unit SU incorporated in the information processing device DPp described with reference to FIG. The hard disk drive 3 usually has a height HH and a width LH.
1, and has a substantially rectangular parallelepiped shape defined by the length LH2.

Shock absorbing holder SAH according to the present embodiment
And the hard disk drives 3 housed and held thereby, the relationship shown in the following formula is established. L1 <LH1 = L1 + ΔL1 (1) L2 <LH2 = L2 + ΔL2 (2) H1 ≦ HH = H1 + ΔH1 (3)

Note that ΔL1, ΔL2, and ΔH1 are
Hardness and elongation of the material forming the shock absorbing holder SAH, width LH1 and length LH of the hard disk drive 3
2 and a value that is appropriately determined based on the height HH. That is, the shock absorbing holder SAH is configured to have a housing space CS that is smaller than the volume of the shock sensitive device that is housed and held.

FIG. 5 shows a state where the hard disk drive 3 shown in FIG. 4 is housed and held in the housing space CS of the shock absorbing holder SAH. In the present embodiment, the shock absorbing holder SAH is made of a material having low hardness and low resilience represented by the above gel material. Therefore, the hard disk drive 3 which is larger than the accommodation space CS
When the housing is housed in the housing space CS, the side walls S1, S
2, S3, and S4, upper plates Tp1, Tp2, Tp3, and Tp4, and lower plates Bp1, Bp2, Bp3, and Bp4. Accommodating space CS
Can be inserted inside.

After insertion, the shock absorbing holder SA is expanded.
Each part of H tries to return to the original length. However, the shock absorbing holder SAH accommodates the hard disk drive 3 having a volume larger than the original capacity in the accommodation space CS. Therefore, the shock absorbing holder SAH is controlled by the hard disk drive 3 by using the ΔL1, ΔL2, and ΔH.
It will be in a stretched state by 1. With the pulling force according to this extension, the shock absorbing holder SAH can be securely held in a state of being in close contact with the hard disk drive 3.

FIGS. 6 and 7 are sectional views taken along line VI-VI and VII- of the shock absorption holding unit SAHB shown in FIG.
VII cross sections are shown respectively. Shock absorption holding unit SA
In the HB, the storage space CS of the shock absorbing holder SAH
By accommodating the hard disk drive 3 therein, the height H1, the width L1, and the length L2 of the accommodation space CS when the shock absorbing holder SAH is alone are H1 ′ and L, respectively.
It is extended to 1'and L2 '. Further, the heights H2 and H3 of the shock absorbing holder SAH are also H2 ′.
And H3 '.

As described above, the shock absorbing holder SA
Since H is in close contact with the housed hard disk drive 3, these dimensions H1 ', L1', and L2 'are
Dimensions HH and LH of hard disk drive 3 respectively
1 and LH2 are almost the same. Therefore, the relationship shown in the following formula is generally established. L1 ′ = LH1 = L1 + ΔL1 (4) L2 ′ = LH2 = L2 + ΔL2 (5) H1 ′ = HH = H1 + ΔH1 (6)

Further, as a result of the above-mentioned expansion (ΔL1, ΔL2, and ΔH1), another dimension T of the shock absorbing holder SAH is obtained.
1, T2, Td, and T4 decrease to T1 ′ and T1, respectively.
2 ', Td', T4 '. In this case, the reduction amounts ΔT1, ΔT2, ΔTd, and ΔT4 of the respective dimensions are the above-described extension amounts (ΔL1, ΔL2, and ΔH1) and the physical characteristics of the constituent material of the shock absorbing holder SAH. Depends on

As shown in FIGS. 5, 6, and 7, a rectangular U-shaped casing of the hard disk drive 3 is provided on the outer periphery of a U-shaped member made of a material having low hardness and low repulsion. Absorption holder SAH formed of an outer wall having a uniform cross-sectional shape is mounted in a state of enclosing the outer circumference of the housing of hard disk drive 3. The shock absorption holding unit SAHB configured as described above is incorporated in the information processing device DPp in the same manner as the storage device unit SU described with reference to FIG. 23.

The shock absorbing and holding unit SAHB configured as described above has the following characteristics even when it is used alone or in a state where it is incorporated in the information processing device DPp. By extending the shock absorbing holder SAH and fitting each side of the hard disk drive 3 into the U-shaped outer wall of the shock absorbing holder SAH, the contracted force of the stretched shock absorbing holder SAH causes The hard disk drive 3 is held in the accommodation space CS. In this way, the work of wrapping the outer periphery of the hard disk drive 3 with the shock absorbing holder SAH is extremely easy.

Further, the shock absorbing holder SAH cannot stand on its own, but if the hard disk drive 3 is fitted to form the shock absorbing holding unit SAHB, it will not lose its shape. Therefore, the information processing device DPp can be easily attached to and detached from the housing 1 in the form of the shock absorbing and holding unit SAHB.

Further, even when the hard disk drive 3 is removed from the housing of the information processing device in the state of the shock absorption holding unit SAHB for the purpose of maintenance or the like, the hard disk drive 3 is safely accommodated and held by the shock absorption holder SAH. To be done.

Since the shock absorbing holder SAH is made of a material having low resilience and low hardness such as a gel material, even if a shock is applied to the shock absorbing holder SAHB,
The shock absorbing holder SAH has the effect of reducing the shock transmitted to the hard disk drive 3 housed therein. This shock propagation attenuation amount is related to the hardness and the low coefficient of restitution of the shock absorbing holder, and the lower the shock absorbing holder is, the thinner and the highly efficient shock absorbing ability can be exhibited.

By using a material having such a property, the shock absorbing holder SAH is absorbed before being transmitted to the hard disk drive 3 in which it is housed,
The hard disk drive 3 can be protected from damage due to impact. The same applies when a shock is applied to the housing of the information processing device while the information processing device is being carried.

Shock absorbing holder SAH in the present embodiment
As a constituent material of, preferably, hardness ASKER / F
By adopting the gel-like polystyrene of P30 to 80, it is possible to obtain the maximum shock absorbing effect and the necessary stretching amount for enclosing and housing the outer shape of the shock sensitive device.

In the shock absorbing holder SAH, the inner dimension of the annular outer wall is set smaller than the outer dimension of the hard disk drive 3, whereby the shock absorbing holder SAH.
When the hard disk drive 3 is mounted on the hard disk drive 3, the degree of adhesion between the shock absorbing holder SAH and the hard disk drive 3 increases, and the shock absorbing effect improves.

Further, the projections P1a, P1b, P2 provided so as to project outside the outer wall of the shock absorbing holder SAH.
Each of a, P2b, P3a, P3b, P4a, and P4b is a shock absorption holder SH when the shock applied to the shock absorption holding unit SAHB or the shock absorption holder SAH.
It is received before being transmitted to the side wall portion S which is the AH main body, the upper plate Tp, and the lower plate Bp. Then, by deforming the projection P itself, the shock is largely absorbed before the shock is transmitted to the shock absorbing holder SAH main body. And
Shock absorbing holder S for absorbing the shock that cannot be completely absorbed by protrusion P
Absorb by AH body. In this way, the projection P and the main body of the shock absorbing holder SAH are deformed in two stages to improve the shock absorbing ability of the shock absorbing holder SAH. Further, the projection P also has an effect of ensuring a space for releasing the deformation amount of the shock absorbing holder SAH deforming for shock absorption.

In the present embodiment, the protrusions P are evenly provided on the side walls S1, S2, S3, and S4, which are opposite to each other on the side faces thereof, but they may be provided only in the weak impact direction. It is good, and it may be provided in a concentrated manner particularly in a place where it is likely to receive an impact. As an example of such a place,
Each corner portion of the shock absorbing holder SAH can be mentioned.

In this embodiment, even when the hardness of the shock absorbing holder is low and the thickness of the shock absorbing holder is thin, the shock absorbing holder retains its self-supporting property when it is stretched and mounted on the hard disk drive 3. Therefore, it is possible to use a shock absorbing holder having a lower hardness, a thin wall, and a high shock absorbing capacity, and a highly efficient shock absorbing capacity can be realized.

Further, since the shock absorbing holder is integrated, the handling is easy and the shock absorbing capacity is stable.

The recesses Ra and Rb provided on the upper surface of the shock absorbing holder SAH ensure a space for allowing the deformation amount to escape when the shock absorbing holder receives a shock.
As an air passage, it has an effect of helping to dissipate heat from the hard disk drive 3.

Further, even if the shock absorbing holder SAH contains a metal filler or has an opening on the side surface, the heat radiation from the hard disk drive 3 can be performed.

As described above, in this embodiment, the shock absorbing holder can be made to have a lower hardness and a thinner wall as compared with the conventional example, the information processing apparatus can be downsized, and the shock absorbing capacity with high efficiency can be realized.

In the present embodiment, the shock absorbing holder having the characteristics of low hardness and low repulsion has a shape in which a U-shaped cross section shorter than the outer peripheral length of the hard disk drive casing is formed in an annular shape. , Any shape that has an internal dimension smaller than the external dimensions of the hard disk drive housing and that is stretched when attached to the hard disk drive and that does not come off, for example, from the top or bottom of the hard disk drive housing You may make it attach two impact absorption holding bodies so that it may pinch | interpose.

Further, in this embodiment, the protrusion P
Is formed in a substantially rectangular shape, but may be formed in a spherical shape, an elliptic spherical shape, or any other shape as long as the shape is suitable for absorbing the shock applied to the shock absorber SAH. Also,
Such a shape of the protrusion P absorbs a shock in relation to the surroundings where the shock absorber SAH housing the hard disk drive 3 is installed or stored, and effectively protects the housed shock sensitive device. It is preferable to determine such a shape that it can be held together.

Further, when further thinning and space saving are required, it is also effective not to provide the projection P on the shock absorber SAH. In this case, the shock absorbing effect due to the deformation of the protrusion P cannot be expected, but the shock can be absorbed by the frame itself of the shock absorber SAH. If the shock absorber S
When the impact absorbing ability of the AH frame is insufficient, the impact absorbing ability of the entire frame can be increased by setting the wall thickness of any or all of the walls S, Tp, and Bp of the frame to be larger. Can be improved. In this way, even if the wall thickness of the frame body is increased, the shock absorber SAH containing the shock sensitive device is housed.
The outer size of can be suppressed to be smaller than that having the protrusion P.

(Second Embodiment) With reference to FIGS. 8, 9, 10, 11, and 12, a shock absorbing and holding unit according to a second embodiment of the present invention will be described. As shown in FIG. 8, the shock absorbing and holding unit SAHBP according to the present embodiment has a structure in which the shock absorbing and holding unit SAHB according to the above-described first embodiment is further housed in the case assembly H. The case H is composed of a lower case 7 and an upper case 8 which are fitted to each other. In the case H, the signal cable 6 of the hard disk drive 3 is taken out and the space H
6 and a void Hr for letting out the heated air coming out from the cooling recess Ra (Rb) provided in the shock absorption holding unit SAHB.

Next, FIG. 9, FIG. 10, FIG. 11 and FIG.
With reference to, the method of configuring the shock absorption holding unit SAHBP will be described in order. As shown in FIG. 9, the lower case 7
Is a substantially rectangular flat plate portion 7p including the outer shape of the shock absorbing and holding unit SAHB, and the shock absorbing and holding unit SAHB.
Side walls 7s1, 7s2, 7s3, and 7s4 having a shape that substantially covers the respective side walls S1, S2, S3, and S4 of
It is composed of a sheet material having. These side walls 7s
As will be described later, 1, 7s2, 7s3, and 7s4 are bent substantially perpendicular to the flat plate portion 7p to form a lower case 7 having a space capable of accommodating the shock absorption holding unit SAHB. The side wall portions 7s1 and 7s2
Has substantially rectangular holes 7h when the shock absorbing and holding unit SAHB is housed, the projections P1a, P1b, P
2a and P2b are preferably provided at positions where they do not abut.

As shown in FIG. 10, the shock absorption holding unit SAHB is placed on the flat plate portion 7p described above. At this time,
Protrusions P1a and P1 provided on the shock absorbing holder SAH
b, P2a, and P2b directly contact the flat plate portion 7p. Therefore, the shock absorption holding unit SAHB is
Spaces are held between p1, Bp2, Bp3, and Bp4 with the flat plate portion 7p.

Next, as shown in FIG. 11, each side wall 7s
Each of 1, 7s2, 7s3, and 7s4 is bent toward the corresponding side wall S1, S2, S3, and S4 of the shock absorbing holder SAH. At this time, the side wall 7s
1 contacts the projections P1a and P1b provided on the side wall S1 of the shock absorbing holder SAH, and does not directly contact the side wall S1. In this way, a space is maintained between the side wall portion 7s1 and the side wall S1. Similarly, the side wall 7
s2, 7s3, and 7s4 are also bent, and the lower case 7 holds the shock absorbing and holding unit SAHB so as to wrap it while keeping a space between the lower case 7 and the shock absorbing and holding unit SAHB.

Next, as shown in FIG. 12, the shock absorbing holding unit SAHB held so as to be wrapped by the lower case 7 is inserted into the upper case 8. The upper case 8 includes a substantially rectangular flat plate portion 8p including the outer shape of the shock absorbing and holding unit SAHB, and a side wall S of the shock absorbing and holding unit SAHB.
1 and S2, and is composed of a sheet material having side wall portions 8s1 and 8s2 having a shape that substantially covers S2. Side wall 8s
1 and 8s2 are bent substantially perpendicular to the flat plate portion 8p to form a space capable of accommodating the shock absorption holding unit SAHB held by the lower case 7 described above. The lower case 7 is provided inside the side wall portions 8s1 and 8s2.
The protrusions 8i corresponding to the holes 7h provided in the side wall portions 7s1 and 7s2 are provided.

In the upper case 8 thus constructed, the lower case 7 holding the shock absorbing and holding unit SAHB is arranged so that the side wall portions 7s1 and 7s2 of the lower case 7 are inside the side wall portions 8s1 and 8s2 of the upper case 8, respectively. Insert to position. At this time, the protrusions 8i provided on the inner walls of the side wall portions 8s1 and 8s2 are fitted into the holes 7h provided in the side wall portions 7s1 and 7s2, so that the upper case 8 and the lower case 7 are securely coupled. It

Since the lower case 7 receives a pressure from the inside by the contained shock absorbing holder SAH, the sheet-like case 7 and the upper case 8 are connected to each other by the connection of the projecting portion 8i and the hole 7h. The hard disk drive 3 wrapped in the shock absorbing holder SAH is held inside to form an integrated unit, which is inserted into the information processing apparatus housing in this state. The upper case 8 may be a chassis for the convenience of mounting the shock absorption holding unit SAHBP thus configured to the information processing apparatus.

In the information processing apparatus of the present embodiment configured as described above, the hard disk drive 3 is wrapped in the shock absorbing holder SAH, and further wrapped in the sheet-like case 7 which can be bent and assembled. Since it can be inserted into the upper case (chassis) 8, it is possible to prevent the shape of the shock absorbing holder from being deformed when the upper case (chassis) 8 is inserted. Furthermore, since the surface of the shock absorbing holder SAH is viscous, by itself,
It is difficult to insert it into the information processing device housing. However, by housing the shock absorbing and holding unit SAHB in the case assembly H, the surface of the shock absorbing body SAH does not come into contact with the information processing device and can be easily attached to and detached from the housing. Then, the material of the shock absorbing holder SAH can be made to have a lower hardness, and the shock absorbing capacity can be greatly improved.

As described above, in this embodiment, it is possible to integrate the hard disk drive protected by the shock absorbing holder having a lower hardness than the conventional example.
The hard disk drive can be easily attached and detached as well as the shock absorption capacity.

In this embodiment, the sheet-shaped case 7 is inserted into the upper case (chassis) 8 and then inserted into the information processing apparatus housing. However, the sheet-shaped case 7 is directly inserted into the information processing apparatus. You may insert in a housing.

In this embodiment, the shock absorber SAH according to the first embodiment described with reference to FIGS.
The example in which the lower case 7 or the upper case 8 is further accommodated has been described. However, the shock absorber SAH can also be configured without the protrusion P as described above. It goes without saying that the shock absorber SAH having no protrusion P may be configured to be housed in the lower case 7 or the upper case 8.

(Third Embodiment) FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, and FIG.
With reference to FIG. 8, a shock absorbing holder and a shock absorbing holding unit according to a third embodiment of the present invention will be described. In the present embodiment, the hard disk drive is housed in the shock absorber, and the first shock absorbing and holding unit is constructed first. Then, the first shock absorbing and holding unit is further housed in another case to form a second shock absorbing and holding unit. First, FIG. 13, FIG. 14, and FIG.
The shock absorbing holder and the first shock absorbing holding unit according to the present embodiment will be described with reference to FIGS.

As shown in FIGS. 13 and 14, the shock absorbing and holding unit SAHB1 according to the present embodiment comprises a hard disk drive 3, a shock absorbing and holding body 21, and a cover 22. Shock absorbing holder 21
Is made of a gel material having low hardness and low repulsion property, and is formed into a box shape having a recess 21c according to the shape of the hard disk drive 3. Side walls 21s1, 21s2, and 21s4 of the shock absorbing holder 21
Each of them is provided with an opening 21h. Further, a concave portion 21r corresponding to the signal cable 6 of the hard disk drive 3 is provided at the center of the side wall portion 21s3.

Recesses 21c and 21r of the shock absorbing holder 21
Respectively, the main body of the hard disk drive 3 and the signal cable 6 are housed therein, and the cover 22 is provided with a recess 21
A shock absorption holding unit SAHB1 is configured by fitting the hard disk drive 3 into the c and pressing the hard disk drive 3.

Next, with reference to FIGS. 15 and 16, the shock absorbing and holding unit SAHB1 alone or in the state where it is incorporated in the information processing apparatus main body causes the housed hard disk drive 3 to drop due to an accidental drop or the like. A case where a shock such as moving in the Ds direction is received will be described.
In this case, by moving the hard disk drive 3,
The shock absorbing holder 21 is deformed as shown in FIG.

The deformation of the shock absorbing holder 21, that is, the shock force is absorbed by the deformation of the opening 21h provided in the side wall portion 21s. Such a deformation of the opening 21h generally reduces the diameter d of the opening 21h to d'in the side wall portion (21s1) to which pressure is applied, as shown in FIG. Note that, in FIG. 16, the shape after the deformation of the opening 21h is expressed as a perfect circle for simplification of description, but it goes without saying that various shapes can be adopted. The opening 21h may be provided in the side wall portion 21s3, and may be provided in an arbitrary number on the side wall portion 21s.

Next, with reference to FIGS. 17, 18 and 19, the second shock absorbing and holding unit according to the present embodiment will be described. Second shock absorption holding unit SAH

The shock absorbing and retaining unit SAHB1 of the metal case 9
After being accommodated in a, it is covered with a metal lid 9b to form an integral unit. The side wall of the metal case 9a is provided with an opening 9h.

A case will be described below in which the shock absorbing and holding unit SAHB2 having the above-described structure receives a shock by an accidental drop or the like while the shock absorbing and holding unit SAHB2 is incorporated in the information processing apparatus main body. Basically, it is the same as when the shock is applied to the shock absorption holding unit SAHB1. However, in the shock absorbing and holding unit SAHB2, since the shock absorbing and holding unit SAHB1 is further unitized by the metal case 9a and the metal lid 9b, basically, the shock absorbing and holding unit SAH due to impact is held.
First, the deformation of H is absorbed by the deformation of the opening 21h, and secondly, the side wall portion 21s has a metal case 9a.
It is absorbed by being deformed so as to project into the opening 9h provided in a.

By deforming a part of the shock absorber SAH like the protrusion 21e shown in FIG. 19,
As shown with the deformation of the opening 21h, the impact force is more effectively absorbed. If these holes were not provided, there would be no escape for the deformed portion of the shock absorbing holder 21, and the shock would increase and be transmitted to the hard disk drive 3 housed by the repulsive force when the shock was received.

As described above, by providing an opening in the shock absorbing holder and the case in which the shock absorbing holder is accommodated, the deformation amount of the shock absorbing holder is released, and as a result, the shock absorbing holder is shock-absorbed. The effect can be activated. In addition,
In the present embodiment, the opening 9h is provided in the lateral direction, but it may be provided in the vertical direction such as the cover 22 and the metal lid 9b. Further, the metal case 9a and the metal lid 9b are not necessarily made of metal, as long as they are materials having a strength capable of sufficiently suppressing the deformation of the outer shape of the shock absorber SAH of the first shock absorbing and holding unit SAHB1 to be housed. good.

Further, the metal case 9a and the metal lid 9
b does not have to be a metal and may be made of a resin having strength according to the application.

In the present embodiment, the shock-sensing device housed by the shock-absorbing holder 21 and the cover 22 having a larger shape than the shock-sensing device is housed by the metal case 9a and the metal lid 9b to hold the shock-absorbing device. It constitutes the unit SAHB1. However, the shock absorber SAH according to the above-described first embodiment (regardless of the presence or absence of the protrusion P) containing the shock-sensitive device is a metal case 9a and a metal lid 9b.
Alternatively, the shock absorption holding unit SAHB1 may be housed in.

(Fourth Embodiment) With reference to FIGS. 20, 21, and 22, a shock absorption holding unit according to a fourth embodiment of the present invention will be described below. Also in the present embodiment, as in the third embodiment, the hard disk drive is housed in the shock absorber to first configure the first shock absorption holding unit, and the first shock absorption holding unit is further separated. The second shock absorbing and holding unit is housed in the case (1) to form the second shock absorbing and holding unit.

As shown in FIGS. 20 and 21, the shock absorbing and holding unit SAHB 'according to the present embodiment has a hard disk drive 3, a resin case 10, a metal case 12a, a metal case lid 12b, a shock absorbing and holding unit. Body 3
1 and a cover 32.

A signal cable 6 having a connector 6a at its tip is connected to the side surface 3a of the hard disk drive 3. The shock absorbing holder 31 is made of a gel material having a low hardness and a low coefficient of restitution, and the recess 3 is formed in accordance with the shape of the hard disk drive 3.
It has 1c. The cover 32 is a shock absorbing holder 31.
The same material is used to form a shape corresponding to the opening of the recess 31c. The resin case 10 is made of a resin sheet and has a shape corresponding to the bottom surface of the recess 31c. The resin case 10 has a shape in which the area of the surface 10a facing the side surface 3a of the flat hard disk drive 3 is wider than that of the side surface 3a.

In this embodiment, the resin case 10 is housed in the recess 31c of the shock absorbing holder 31. Then, the hard disk drive 3 is placed on the resin case 10.
Are placed and housed. Next, the cover 32 is inserted into the resin case 10 and presses the hard disk drive 3 housed in the recess 31 c of the shock absorbing holder 31. As described above, the hard disk drive 3 is wrapped with the resin case 10, the shock absorbing holder 31, and the cover 32 to form the first shock absorbing holder unit SA.
HB1 'is configured.

This first shock absorption holding unit SAHB
1'is a metal case 12a and its lid 12b,
The second shock absorbing holding unit SAHB2 ′ is configured to be wrapped and housed. At this time, the connector 6a is fixed to the metal case 12a. The length of the signal cable 6 is longer than the maximum deformation amount of the shock absorbing holder by more than the creepage distance from the outlet of the signal cable 6 of the hard disk drive 3 to the connector 6a. Then, in this state, the hard disk drive block (second
The shock absorbing and holding unit SAHB2 ') is housed in the storage section 1c of the housing 1 of the information processing device DPp.

With reference to FIG. 22, the first shock absorbing and holding unit SAHB1 ′ and the second shock absorbing and holding unit SAHB2 ′ according to the present embodiment are in a state when a shock is applied in the lateral direction of the hard disk drive 3. Will be explained. The hard disk drive 3 has a side surface 3b
When receiving a shock that moves in the direction of, that is, in the Fr direction, the resin case 10 arranged between the shock absorbing holder 31 and the hard disk drive 3 first receives the movement of the hard disk drive 3.

The resin case 10 includes a shock absorbing holder 31.
The hardness is higher than that of the hard disk drive 3 and it has an appropriate repulsive force, and is bent by the pressing force of the side surface 3b of the hard disk drive 3. By bending the resin case 10 in this way,
The impact force applied to the hard disk drive 3 can be absorbed to some extent. Furthermore, the impact force that cannot be completely absorbed can be dispersed to a larger area than the side surface 3b of the hard disk drive 3 and transmitted to the impact absorption holder 31.

As a result, the hard disk drive 3 does not bite into the shock absorbing holder 31, and even the shock absorbing holder having a thin thickness, low hardness and low coefficient of restitution is combined with the resin case. As a result, the shock absorbing effect can be maintained. As a result, it is possible to contribute to downsizing of the information processing device.

Further, by disposing a metal case further outside to form a hard disk drive block, it is possible to easily attach / detach the information processing apparatus to / from the housing.
Even when the hard disk drive block is removed from the housing of the information processing device for the purpose of maintenance or the like, the hard disk drive remains in the shock absorbing structure. Therefore, even if the hard disk drive block is impacted, the hard disk itself is not damaged.

Further, since the signal cable 6 of the hard disk drive 3 is set longer than the deformation amount of the shock absorbing holder, the shock may be applied to the hard disk drive 3 when the information processing apparatus is shocked or when the information processing apparatus is detached. Even in the case of, the signal cable 6 is flexibly deformed without being affected by the movement or operation of the hard disk drive 3 to maintain the electrical connection. Further, since the signal cable 6 is inside the hard disk drive block and only the connector 2b appears outside the hard disk drive block, handling is not troublesome and connection with the circuit board 2 in the information processing device is very simple. Is. In this way, it is possible to improve the workability of attaching and detaching the hard disk drive and to maintain a high shock absorbing structure at the time of attaching and detaching.

In the present embodiment, the shock absorbing holder 31 and the cover 32 are separate parts made of the same material, but they are integrally molded, or the shock absorbing holder 31 and the cover 32 are made of different materials. It may be configured.

Further, instead of the resin case, if a sheet-like thin resin material or a metal component is integrally used by a method such as integral molding or welding, the shock absorbing holder is not limited to the same effect. Also, the shock absorption performance is stable, and handling during assembly and replacement becomes easy.

Further, although the metal case is arranged on the outer side, the same applies when the outer side is constituted by a resin case or the like instead of the metal.

In the embodiments described above, the hard disk drive is taken as an example, but it goes without saying that it is useful for all other magnetic disk devices, optical disk devices, and other devices susceptible to impact.

As described above, according to the present invention, the hard disk drive is loaded with a shock absorbing holder having an inner dimension smaller than the outer dimension of its housing and having low hardness and low repulsion characteristics while being stretched. Wrap the hard disk drive with a shock absorber. Further, by wrapping the shock absorbing holder in a foldable sheet-like case and inserting these into the information processing device housing, a shock absorbing holder having low hardness and low repulsion can be obtained.
Can be worn while maintaining independence.

With the above effects, it is possible to make the shock absorbing holder thinner and to use a shock absorbing holder having a lower hardness. Furthermore, the shock absorbing capacity of the shock absorbing holder that protects the hard disk drive from external shock applied when carrying it can be enhanced.

Moreover, between the hard disk drive and the hard disk drive, which is arranged so as to surround the hard disk drive and has a low hardness and a low coefficient of restitution, a higher hardness and a higher coefficient of restitution than the shock absorbing holder. An elastic body having the characteristics described above is interposed. Further, the outer side of the shock absorbing holder is wrapped in a high-hardness case, and is housed in the information processing device housing, so that the thickness of the shock absorbing holder is reduced, and a space-saving and highly efficient shock absorbing structure is provided. Can be realized. As a result, it is possible to further reduce the size of the information processing device that is resistant to shock.

Further, the signal cable pulled out from the hard disk drive is provided inside the case, and the connector of the signal cable is arranged outside the case so that the length of the signal cable is longer than the creepage distance from the signal cable outlet to the connector. By making the shock absorbing holder longer than the maximum deformation amount, the workability of attaching and detaching the hard disk drive can be improved and the high shock absorbing structure can be maintained even when detached and carried, which is extremely useful. is there.

Further, in the present embodiment, the resin case 10 or the elastic member corresponding thereto is used as the above-mentioned first and second
It goes without saying that the same effect as that of the present embodiment can be obtained by providing the shock absorbing holder and the shock sensitive device according to the second and third embodiments.
