Description

Disc-type record carrier driving apparatus and electronic apparatus having the same

The present invention relates to a disk-type record carrier driving device such as an optical disk device, a magneto-optical disk device, and a hard disk device having a sensing element that stores a disk-type record carrier and can move relative to the disk-type record carrier. The present invention relates to an electronic apparatus including a mobile communication system such as a mobile system such as a media player, a mobile Internet device, a portable videophone terminal, a PDA, and a micro PC, or an in-vehicle navigator system.

An optical disk device, a magneto-optical disk device, a hard disk device, etc. having a sensing element capable of storing a conventional disk-type record carrier and moving relative to the disk-type record carrier have a storage unit for storing a disk-type record carrier having an information recording surface; And a flat, substantially rectangular parallelepiped main body having a total of six surfaces including a pair of main surfaces, a pair of main side surfaces, and a pair of sub-side surfaces.
And the fixing which provided the opening which can mount | wear with the fixing member for fixing to the electronic device which mounts the apparatus in the part of both sides of the main side surface near the four corners of the main surface of the main-body part, or the sub-side surface both sides The portions are provided so as to protrude from the side surfaces.
In addition, the electronic device in which the device is mounted is used for mobile communication systems such as personal media players, mobile Internet devices, mobile phones, mobile videophone terminals, PDAs, ultra-small PCs, mobile systems, or in-vehicle navigator systems. For example, since it is required to increase the shock absorbing function to improve the shock resistance and vibration resistance, the fixing portion is opened in a C shape, for example, a damper, a bumper, or an insulator. It is fixed by inserting a screw through an anti-vibration part that is processed into a desired shape using a material having a small elastic modulus.

First, in the case shown in the partial perspective view of the disk device in the prior art of FIG. 9, the position of the guide shaft 94 is regulated by the holding member 900 and the second support member 95 secured to the chassis 98 by screws 97. The pressure piece 91 is urged downward, the second contact piece 92 is in contact with the end surface of the guide shaft 94, and the notch 96 is attached in a state regulated at a predetermined position.
Here, a rubber vibration isolating portion 99 having a C-shaped opening at the four corners of the chassis 98 and having both ends enlarged in diameter is attached to the opening (not shown) and fixed with screws (not shown) ( For example, see Patent Document 1).

In addition, a disk drive (see, for example, Patent Document 2) provided with a vibration isolating portion at either of the four corners of the pair of main surfaces of the main body, a pair of main surfaces, a pair of main side surfaces, and a pair of sub side surfaces There is an information storage device provided with a substantially L-shaped anti-vibration portion as viewed from the main surface side so as to cover the four corners of all six surfaces (see, for example, Patent Document 3).

Furthermore, a fixed portion having an opening through which a screw is inserted is provided on both sides of either one of the pair of main side surfaces or the pair of sub-side surfaces, and an opening through which the screw is similarly inserted is provided on one surface of the fixed portion. A disk device (see, for example, Patent Document 4) in which a plate-shaped vibration isolating portion is provided and both are fixed, and a fixing portion protruding on both sides is provided on either the pair of main side surfaces and the pair of sub side surfaces, There has been a mechanical deck built in an optical disk reproducing apparatus provided with a vibration isolating portion so as to surround only the base portion of the fixed portion (see, for example, Patent Document 5).

JP 2007-66371 A JP 2005-71568 A JP 2007-317324 A JP 2002-15553 A JP-A-8-287667

However, in the conventional configuration, for example, the configurations of (Patent Document 1) and (Patent Document 5), it is easy to regulate the position of fixing the chassis of the disk device mounted on the electronic device. The shock absorbing area of the anti-vibration part is small because the anti-vibration part interposed between them is fixed with screws or a frame, so most of the shock vibration applied to the electronic equipment is not sufficiently absorbed by the anti-vibration part. The shock vibration is transmitted to the main body of the disk device, and the large displacement that occurs instantaneously causes damage to the disk cartridge stored in the main body storage, or damages the optical pickup constituting the main body and the surrounding mechanism. Or had a problem of malfunction.

In (Patent Document 2) and (Patent Document 3), although the impact resistance and the vibration resistance can be improved, the four corners of the main surface are covered with the vibration isolating portion, so the device is mounted by the height. It is not suitable for mobile electronic devices that are required to be thinner, such as personal media players, mobile Internet devices, mobile phones, portable videophone terminals, PDAs, and ultra-compact PCs. Had problems.

In addition, (Patent Document 4) is effective in dropping impact of the disk device itself, but the disk device is not configured to be mounted on other electronic devices. And the vibration resistance cannot be improved.

The present invention solves the above-mentioned conventional problems, and provides a disk-type record carrier driving apparatus and an electronic apparatus including the same, which have improved shock resistance and vibration resistance by increasing the shock absorbing function despite being thin. The purpose is to provide.

According to the disk type record carrier driving apparatus of the present invention, a storage unit for storing a disk type record carrier having an information recording surface, and a built-in storage unit at the time of rotation of the disk type record carrier stored in the storage unit A pair of main surfaces located in a direction parallel to the recording surface, a pair of main side surfaces, a pair of main surfaces and a pair of main side surfaces connected in a direction perpendicular to the pair of main surfaces and parallel to each other. A flat, substantially rectangular parallelepiped body portion having a total of six surfaces with a pair of sub-side surfaces connected in parallel to each other in a vertical direction, and a pair of main side surfaces and a pair of sub-side surface four side surfaces. A vibration isolating portion that protrudes at all and has a height smaller than the interval between the pair of main surfaces in a direction perpendicular to the pair of main surfaces. In any of all six directions The shock absorption area, which is the contact area between the fixed part of the electronic device on which the disc-type record carrier device according to the present invention is mounted and the vibration isolator of the apparatus, is increased, and the entire surface of the vibration isolator is uniformly applied. Because it comes into contact, it is possible to improve impact resistance and vibration resistance.
In addition, since the height of the vibration isolator is added to the height of the main body and the overall height of the device does not increase, it is easy to reduce the thickness and the surface of the vibration isolator is lower than the main surface. By contacting the fixing part of the electronic device equipped with the disc type record carrier device according to the above, it is easy to make the electronic device thin, and it is not necessary to use a screw to fix both. Thus, a more uniform fixing stress can be obtained over the entire abutting surface.

According to the disk-type record carrier driving device of the present invention, the vibration isolator grips the tip end of the connecting portion protruding from the side surface of the main body, and the tip end surface of the anti-vibration portion is more predetermined than the tip end surface of the connecting portion. It protrudes by a distance and the height of the vibration isolator is larger than the height of the connecting part, so that it is fixed in a state where a predetermined gap is maintained with the casing of the electronic device on which the disc type record carrier device according to the present invention is mounted. Even if it receives impact vibration from the outside, the fixed part of the electronic device does not directly contact the connection part or the main body part, and the shock vibration energy is not fixed to the fixed part and the connection part of the electronic device. Is sufficiently absorbed by the vibration isolating part interposed between the two, so that the impact resistance and vibration resistance can be improved.

According to the disk type record carrier driving device of the present invention, in the vibration isolator, only one of the surfaces parallel to the pair of main surfaces is more predetermined than the main surface in the direction perpendicular to the pair of main surfaces. Projecting in the projecting direction, a gap of a predetermined distance is formed between the projecting direction and the inner surface of the housing of the electronic device on which the disc-type record carrier device according to the present invention is mounted, and the impact vibration received by the electronic device Since it does not buffer directly on the main body, it is possible to improve the impact resistance and vibration resistance.

According to the disk type record carrier driving apparatus of the present invention, the first vibration isolation portion provided on any one of the four side surfaces is connected in a direction perpendicular to the side surface on which the first vibration isolation portion is provided. By connecting the second vibration isolating portion provided on another side surface and making the connecting portion a fan shape when viewed from the main surface side, the corner portion of the vibration isolating portion has an arc shape. Even when an external impact vibration is applied to an electronic device equipped with a disc-type record carrier device, the local stress absorption between the corner portion and the fixed portion in contact with the corner portion can be avoided. Displacement that occurs instantaneously becomes small, and it is possible to improve impact resistance and vibration resistance.

According to the disk type record carrier driving device of the present invention, the hardness of the material constituting the fan-shaped connecting portion is set to be at least larger than the hardness of the material constituting the first vibration isolating portion or the second vibration isolating portion. Therefore, compared to the case where the vibration isolator is made of a single material, the joint part with high hardness works effectively even when receiving a larger impact force, and the displacement of the main body when absorbing impact energy Since the amount is suppressed, the gap that needs to be provided between the inner surface of the casing of the electronic apparatus on which the disc-type record carrier device according to the present invention is mounted can be further reduced, so that the thickness can be reduced.

According to the disk-type record carrier driving device of the present invention, a plurality of vibration isolating portions are provided on any one of the four side surfaces, and a part constituting the main body portion projects from the side surfaces between the plurality of vibration isolating portions. As a result, an interface for connecting to an electronic device in which the disk type record carrier device according to the present invention is mounted via a flat cable or a mechanism for making the disk type record carrier detachable from a storage part built in the main body part. Since it is possible to dispose a part constituting the main body such as a head, it is easy to mount the electronic device on which the disk-type record carrier device according to the present invention is mounted.
In addition, since a part of the mechanism that makes the disc-type record carrier detachable in the storage part built in the main body part or a part that constitutes the main body part such as an open lever of the upper chassis and a storage part opening / closing detection sensor can be arranged, Thinning becomes possible.

According to the disc type record carrier driving apparatus of the present invention, the main body portion has a mechanism for detachably storing the disc type record carrier in the storage portion, so that, for example, cost advantage per capacity, random accessibility, moving image It is possible to store a carrier such as an optical disk having features such as the ability to record content having a large amount of data at low cost, such as personal media players, mobile Internet devices, mobile phones, The optical disk device can be easily mounted on mobile electronic devices such as portable videophone terminals, PDAs, and micro PCs.

According to the disk type record carrier driving apparatus of the present invention, the material of the vibration isolator is made of an elastomer, so that it is possible to greatly improve impact resistance and vibration resistance. Moreover, it is suitable for injection molding and split molding because of its physical properties and has a high degree of freedom in shape.

According to the disk-type record carrier driving apparatus of the present invention, the storage unit can store the disk-type record carrier in the form of a disk cartridge, so that the quality stability of the disk-type record carrier can be easily ensured.

A connecting portion that protrudes at all and has a height smaller than the distance between the pair of main surfaces in a direction perpendicular to the pair of main surfaces. In any of all six directions Since the anti-vibration part can be easily attached, the impact which is the contact area between the fixed part of the electronic device mounting the disc type record carrier device according to the present invention and the anti-vibration part attached to the connection part of the apparatus Since the absorption area is sufficiently secured and the fixed portion uniformly contacts the entire surface of the vibration isolating portion, it is possible to improve the impact resistance and vibration resistance.

According to the electronic apparatus of the present invention, a storage unit that stores a disk-type record carrier having an information recording surface, and a storage unit that incorporates the storage unit and is parallel to the recording surface when the disk-type record carrier stored in the storage unit is rotated. Perpendicular to the pair of main surfaces, the pair of main surfaces, the pair of main surfaces, and the pair of main surfaces that are connected in a direction perpendicular to the pair of main surfaces and in a direction perpendicular to the pair of main surfaces.

As a result, the shock absorption area, which is the contact area between the fixed part of the electronic device and the vibration isolating part of the present apparatus, is increased, and the entire surface of the vibration isolating part is uniformly contacted. Improves vibration resistance.
In addition, since the height of the vibration isolator is added to the height of the main body and the overall height of the device does not increase, it is easy to reduce the thickness and the surface of the vibration isolator is lower than the main surface. By contacting the fixing part of the electronic device equipped with the disc type record carrier device according to the above, it is easy to make the electronic device thin, and it is not necessary to use a screw to fix both. With this method, a more uniform fixing stress can be obtained over the entire contact surface without any fixed stress acting, and the impact resistance and vibration resistance of the mounted disk type record carrier device can be improved despite the thinning of the electronic equipment. Therefore, higher reliability can be ensured.

According to the electronic device of the present invention, the electronic device has the inner wall surface or the inner bottom surface facing each other with a predetermined gap between the main surface, the main side surface, or the sub-side surface, and the buffer material is provided in the gap. The vibration and impact received by the disk is prevented from being transmitted directly to the main body of the disc-type record carrier drive device, and the shock absorber also has the effect of damping the vibration of the main body generated in a predetermined gap, making it more shock resistant. And vibration resistance can be improved.

According to the disk type record carrier driving apparatus according to the present invention, the impact absorption area can be increased despite the reduction in thickness, and the improvement in impact resistance and vibration resistance can be realized.
According to the electronic apparatus equipped with the disk type record carrier driving apparatus according to the present invention, the shock resistance and vibration resistance of the disk type record carrier driving apparatus mounted can be improved despite the thinning of the electronic apparatus. Higher reliability can be secured.

Further, the height of the main body 13 (corresponding to the distance Hd) is added to the height Hf of the vibration isolator 14f or the height Hr of the vibration isolator 14r, so that the overall height of the apparatus does not increase, so that the thickness is reduced. Is easy.
In addition, a fixed portion or an inner mounting surface of an electronic device in which the disc type record carrier device 11 is mounted is brought into contact with the upper, lower, and side surfaces of the vibration isolator 14f and the vibration isolator 14r that are lower than the main surface Sa. This makes it easy to reduce the thickness of the electronic device and eliminates the need to use a screw to fix the both, so that a local fixing stress does not act on the entire contact surface of the two. Fixed stress is obtained.

The anti-vibration part 14f and the anti-vibration part 14r hold the tip of the connecting part 13d protruding from the main side Sb and the sub-side face Sc of the main body 13, and the anti-vibration part 14f and the anti-vibration part 14r It protrudes by a predetermined distance from the tip surface of the connecting portion 13d, and the height of the vibration isolating portion 14f and the vibration isolating portion 14r is larger than the height of the connecting portion 13d.
With this configuration, even when a large vibration from outside or an impact vibration of dropping is applied to an electronic device (for example, see Embodiment 2) on which the disc-type record carrier device 11 according to the present invention is mounted, the fixing unit included in the electronic device The inner mounting surface does not directly contact the connection part 13d or the main body part 13, and the vibration vibration energy is interposed between the electronic device and the connection part 13d by the vibration isolation part 14f and the vibration isolation part 14r. Since it is sufficiently absorbed, it is possible to improve impact resistance and vibration resistance.

Further, only one of the pair of main surfaces Sa parallel to the pair of main surfaces Sa of the anti-vibration unit 14f and the anti-vibration unit 14r is a predetermined distance from the main surface Sa in a direction perpendicular to the pair of main surfaces Sa. It has a configuration that protrudes.
With this configuration, a gap of a predetermined distance is generated between the mounting surface on the inner side of the casing of the electronic device on which the disc type record carrier device 11 according to the present invention is mounted in the protruding direction, and the impact vibration received by the electronic device. Is not directly buffered in the main body 13, so that it is possible to improve the impact resistance and vibration resistance.
The first vibration isolating portion 14f1 provided on the main side surface Sb is connected to a second vibration isolating portion 14f2 provided on another sub-side surface Sc connected in a direction perpendicular to the main side surface Sb. Since the connecting portion 14f3 has a fan shape when viewed from the main surface Sa side, the corner portion of the vibration isolating portion 14f has an arc shape, so that the electronic device in which the disc type record carrier device 11 according to the present invention is mounted is externally provided. Even when impact vibration in the rotational direction is applied, extremely local stress absorption between the corner portion and the fixed portion that abuts on the corner portion is avoided, so that the momentary displacement that occurs is also reduced, resulting in impact resistance. Improvement in vibration and vibration resistance.

Also, a plurality (two) of the vibration isolator 14r are provided on the main surface Sb on the back side, and a partial product such as an interface 13h constituting a part of the main body 13 between the plurality of vibration isolator 14r is the main side. It is the structure which protruded rather than Sb.
With this configuration, since it becomes easy to connect to an electronic device on which the disc-type record carrier device 11 according to the present invention is mounted via a flat cable, it is easy to mount on the electronic device.
Similarly, a part of the mechanism that enables the optical disk D to be attached to and detached from the storage unit 12 incorporated in the main body unit 13 or a part that constitutes the main body unit 13 such as an open lever of the upper chassis 13a or a storage unit open / close detection sensor is similarly used. If arranged, the thickness can be further reduced.

The height Hf of the vibration isolator 14f described above, the height Hr of the vibration isolator 14r, the distance Tf at which the anti-vibration portion 14f protrudes from the distal end surface of the connection portion 13d, and the vibration isolator 14r is the distal end of the connection portion 13d. The distance Tr protruding from the surface, the distance Ht from which the vibration isolating portions 14f and 14r protrude from the main surface Sa, the weight of the disc type record carrier driving device 11 according to the present invention, the material of the vibration isolating portion 14f and the vibration isolating portion 14r, Shock absorption area (contact area) between a fixed part or an inner mounting surface provided inside the electronic device and the vibration isolating part 14f or the vibration isolating part 14r, and further required impact resistance and vibration resistance. What is necessary is just to set suitably according to the level of sex.

In the case of the first embodiment, the total weight of the main body 13 of the disc-type record carrier device 11 is about 25 g, the outer dimensions of the main body 13 are about 44 mm in the width of the main side Sb, and the width of the sub-side surface Sc. Is set to about 43 mm, the height (corresponding to the distance Hd) is set to about 9.5 mm, and the elastomer is selected as the material of the vibration isolator 14f and the vibration isolator 14r. Alternatively, the distance Bf protruding from the sub-side surface Sc is 2.0 to 5.0 mm, the height Hf of the vibration isolation portion 14f is 1.0 to 3.5 mm, and the distance that the vibration isolation portion 14f protrudes from the tip surface of the connection portion 13d. Tf is 0.5 to 3.0 mm, the distance Br protruding from the main side surface Sb of the vibration isolator 14r is 4.0 to 7.0 mm, the height Hr of the vibration isolator 14r is 1.0 to 3.0 mm, The anti-vibration part 14r protrudes from the front end surface of the connection part 13d. The release Tr 0.5 ~ 3.0 mm, vibration isolating unit 14f, 14r is be more preferably 0.5 ~ 2.0 mm the distance Ht projecting from the main surface Sa.

Further, as the material of the vibration isolator 14f and the vibration isolator 14r, a rubber-like elastic body having a high impact absorbing function and a small elastic modulus is more preferable. Particularly, the elastic modulus is 0.23 MPa to 3. An elastomer in the range of 4 MPa is physically suitable for injection molding and parting molding and has a high degree of freedom in shape.
In addition, plastic foam (for example, polyurethane foam, epoxy resin foam, silicon foam, etc.), leather, fiber, etc. may be used.

Further, the anti-vibration part 14f and the anti-vibration part 14r are mounted on the fixing part and the internal part of the electronic device using a method such as two-color molding in which different materials, for example, resin and silicone rubber are molded in the same mold and integrated. Materials having different elastic moduli and different hardnesses may be mixed and molded depending on the direction in contact with the surface or the like.
For example, when two-color molding is performed using an elastomer as the vibration isolating portion 14f, the duro hardness A of the material constituting the fan-shaped connecting portion 14f3 is set to about 30 and the first vibration isolating portion It is preferable to set the durometer A of the material constituting the 14f1 and the second vibration isolator 14f2 to about 20, compared to the case where they are configured with a single material having the durometer A set to about 20, Even when a larger impact force is applied, the connecting portion 14f3 having a higher hardness effectively acts to suppress the displacement of the main body 13 when absorbing the impact energy by 2% to 19%. Since the gap that needs to be provided between the inner surface of the casing of the electronic device on which the device 11 is mounted can be further reduced, the thickness can be reduced.

Further, as a method of attaching the vibration isolator 14f and the vibration isolator 14r to the connecting portion 13d, the connecting portion 13d is simply covered with the above-mentioned material that is molded in advance so as to have an external dimension or a predetermined concave portion. A method may be used, or a method of integrally forming the anti-vibration part 14f or the anti-vibration part 14r and the member constituting the connection part 13d by different material molding, in-mold molding, insert molding, or the like.
It should be noted that the above-described anti-vibration part 14f and anti-vibration part 14r may be provided so as to protrude from the main side surface Sb or the sub-side surface Sc, and the base portion thereof is not necessarily in direct contact with the main side surface Sa or the sub-side surface Sc. There is no need to let them.
Therefore, in a static state free from vibration and impact, for example, in the case of the first embodiment, between the vibration isolator 14f and the main side surface Sb or the sub-surface Sc, and between the vibration isolator 14r and the main side surface Sb. If so, providing a gap of about 0.5 mm in advance (about 1.0 mm at the maximum) may improve the shock absorption rather.

Further, in order to easily ensure the quality stability of the optical disc D which is a disc-type record carrier, the storage unit 12 which can be opened and closed has been described using a form that can be stored in the form of a disc cartridge C containing the optical disc D. However, the present invention is not limited to this, and may be a storage unit that can store a single optical disk D, or a tray type or slot type storage that can store even a disk cartridge C. Department may be sufficient.
Further, the main body 13 is not a form in which the storage part 12 provided with an opening on one side can be opened and closed. For example, the main body 13 can also be applied as a main part of a sealed hard disk device incorporating a magnetic disk or a magneto-optical disk. .

Next, a modified example of how to provide the vibration isolator in the first embodiment will be described with reference to FIGS.
First, in the modification shown in FIG. 5A, the connection portion 23d is formed integrally with a member constituting the main body portion 23 and protrudes from the main side surface Sb.
Here, the vibration isolator 24 provided so as to cover and grip the distal end surface of the connecting portion 23d is the main surface Sa in a direction perpendicular to the pair of main surfaces Sa that are parallel to each other. The height Hf of the vibration isolator 24 is larger than the height Hs of the connecting portion 23d, and further protrudes by a distance Tf from the tip surface of the connecting portion 23d. Yes.

In such a modification, in the vibration isolator 24, one of the surfaces parallel to the pair of main surfaces Sa is a predetermined distance from the main surface Sa in a direction perpendicular to the pair of main surfaces Sa. It does not have a configuration of protruding.
Therefore, a gap of a predetermined distance is secured between the inner surface of the casing of the electronic device on which the disc type record carrier device having such a configuration is mounted, and shock vibration received by the electronic device is directly buffered in the main body. In order to eliminate the problem, it is necessary to appropriately change the fixing portion of the electronic device from the inner surface of the casing. However, it is possible to realize the improvement in impact resistance and vibration resistance as described above.

The height Hf of the vibration isolating portion 34 is larger than the height Hs of the connection portion 33d, and further protrudes by a distance Tf from the tip surface of the connection portion 33d. Yes.
In such a modification, the member constituting the main body 33 and the connecting portion 33d are configured separately, so that the configuration is complicated, but the connection is made by different material molding, in-mold molding, insert molding, or the like. It is also possible to select a material different from the material of the main body 33 made of a resin material, for example, a metal material that can be processed thinner or a material having a smaller elastic modulus than the resin material as the material of the portion 33d.
Further, instead of integrally forming the connecting portion 33d and the main body portion 33, the connecting portion 33d and the vibration isolating portion 34 may be integrally formed, or all of the main body portion 33, the connecting portion 33d and the vibration isolating portion 34 may be formed. It may be integrally molded.

Next, in the modification shown in FIG. 5C, the interface 45 is fixed in a state of being sandwiched by the main body 43, and one end of the interface 45 is connected to the electronic device side and the flat cable 46 indicated by a broken line. ing.
The vibration isolator 44 provided on the main surface Sb side is provided so as to sandwich the interface 45 from above and below, and the distance between the main surfaces Sa in a direction perpendicular to the pair of main surfaces Sa that are parallel to each other. The height Hf is smaller than Hd.
In such a modification, since an interface for connecting to the electronic device side via the flat cable 46 can be arranged, it is easy to mount the electronic device on which the disc type record carrier device according to the present invention is mounted.

And in the modification shown in FIG.5 (d), the vibration isolator 54 is fixed by the side surface Sb side in the state pinched | interposed by the main-body part 53, and a pair of main surface which has a mutually parallel positional relationship. The height Hf is smaller than the distance Hd between the main surfaces Sa in the direction perpendicular to Sa.
In such a modification, since it is not necessary to attach the vibration isolator 54 via the connection part as described above, the structure can be further simplified.

Next, a modification of the arrangement method of the vibration isolator in the first embodiment will be described with reference to FIGS. 6 (a) to 6 (c).
FIG. 6A shows a substantially I-shaped prevention at the center of all four side surfaces of the pair of main side surfaces Sb and the pair of sub-side surfaces Sc of the disc-type record carrier driving device 61 as viewed from the main surface Sa side. FIG. 6B shows a case where the vibration part 62 is provided, and FIG. 6B shows a portion close to the four corners of the main surface Sa in all four side surfaces of the pair of main side surfaces Sb and the pair of sub-side surfaces Sc of the disk type record carrier driving device 71. FIG. 6C shows a case where a substantially L-shaped vibration isolator 72 is provided when viewed from the main surface side, and FIG. 6C shows four side surfaces of the pair of main side surfaces Sb and the pair of sub-side surfaces Sc of the disk-type record carrier driving device 81. In this case, the vibration isolator 82 is provided so as to surround the entire circumference of the main side surface Sb and the sub-side surface Sc as seen from the main surface Sa side.

As described above, the positional relationship of the vibration isolator with respect to the main body is not limited only to the present embodiment and its modified examples, and does not require symmetry in the vertical and horizontal directions, What is necessary is just to set suitably in consideration of the positional relationship with the fixing | fixed part of an electronic device which mounts this apparatus, or an internal mounting surface, the required impact resistance, vibration resistance, etc.

(Embodiment 2)
FIG. 7 is an exploded view of the electronic device according to the second embodiment of the present invention, and FIG. 8A is a cross-sectional view taken along the CC line after the electronic device shown in FIG. 7 is assembled. FIG. 7B is a cross-sectional view taken along the arrow DD after the electronic apparatus shown in FIG. 7 is assembled.
Here, the same reference numerals are used for the disc-type record carrier driving apparatus 11 described in the first embodiment, and the description overlapping the above description is omitted.

First, as shown in FIG. 7, the disk-type record carrier driving device 11 includes an anti-vibration unit 14f or an anti-vibration unit 14r protruding from each side surface. After the electronic device 100 (see FIGS. 8A and 8B) is mounted in a rectangular mounting space surrounded by the inner bottom surface 201a and the inner wall surface 201b of the lower case 201, the liquid crystal display 102 and the push button switch 103 are mounted. The upper case 101 provided with a fixing portion 101a and a fixing portion 101b (see FIGS. 8A and 8B) is superimposed on the lower portion.
As a result, as shown in FIG. 8A or FIG. 8B, the lower surface of the vibration isolator 14f and the vibration isolator 14r provided in the disc type record carrier driving device 11 is perpendicular to the main surface Sa. The inner bottom surface 201a (see FIG. 7) of the lower case 201 from the lower direction is the direction of the upper case 101 from the upper direction which is perpendicular to the main surface Sa on the upper surfaces of the vibration isolating portion 14f and the vibration isolating portion 14r. The fixed portion 101a and the fixed portion 101b are in contact with each other in the direction indicated by the dashed arrows.

Then, the inner wall surface 201b (see FIG. 7) of the lower case 201 is in contact with the left side surface of the vibration isolating portion 14f from the left direction, which is a direction perpendicular to the main side surface Sb, in the direction indicated by the one-dot chain line arrow. The inner wall surface 201b (see FIG. 7) of the lower case 201 is in contact with the right side surface of 14r from the right direction, which is a direction perpendicular to the main side surface Sb, in the direction indicated by the dashed line arrow.
Further, on the other side surface of each of the vibration isolating portion 14f and the vibration isolating portion 14r, the inner wall surface 201b (see FIG. 7) of the lower case 201 from the direction perpendicular to the sub-side surface Sc is a direction indicated by a two-dot chain line arrow. In contact with the main body 13 (see FIG. 2) of the disk-type record carrier driving device 11 and the inner surface of the electronic device 100 while ensuring a predetermined gap, It can be fixed while securing a predetermined elastic force in all three directions in the left-right direction.
That is, a predetermined gap is ensured between the main body 13 (see FIG. 2) of the disk type record carrier driving device 11 and the inner surface of the electronic device 100, and the main body is always provided via the anti-vibration unit 14f and the anti-vibration unit 14r. By holding 13, vibrations and shocks received by the electronic device 100 are prevented from being directly transmitted to the main body 13 of the disk-type record carrier driving device 11, and these vibrations and shocks are prevented from the vibration isolating part 14 f and the vibration isolating part 14 r. In this case, the effect that the energy of vibration and impact is transmitted to the main body 13 after being absorbed and attenuated is obtained.

As described above, the shock absorbing area, which is the contact area between the vibration isolator 14f and the vibration isolator 14r of the fixed unit 101a or the fixed unit 101b of the electronic device 100 and the disc type record carrier driving device 11, is increased, and the Since the entire surface of the vibration portion 14f and the vibration isolation portion 14r is in uniform contact with each other, it is possible to improve impact resistance and vibration resistance.
In this case, the inner bottom surface 201a and the inner wall surface 201b of the lower case 201 constitute a fixing portion for the vibration isolating portion 14f or the vibration isolating portion 14r, although they are not referred to as fixing portions.
In order to secure a predetermined gap between the main surface Sa, the main side surface Sb or the sub-side surface Sc of the main body 13 and the inner wall surface 201b or the inner bottom surface 201a of the electronic device 100 opposed to the main surface Sa via the predetermined gap. In addition to the materials such as elastomers described above as cushioning materials, electronic materials can be obtained by appropriately inserting a thin plate-shaped sponge material such as low-flammability urethane, soft urethane foam, or conductive urethane into the gap. Since vibrations and shocks received by the device 100 are prevented from being directly transmitted to the main body 13 of the disk-type record carrier driving apparatus, the buffer material also has the effect of attenuating the vibration of the main body 13 generated in a predetermined gap. Impact resistance and vibration resistance can be improved.

In a static state where there is no vibration or impact after the disc-type record carrier driving device 11 is mounted in a rectangular mounting space surrounded by the inner bottom surface 201a and the inner wall surface 201b of the lower case 201 of the electronic device 100. The fixed portion 101a or the fixed portion 101b does not necessarily need to be brought into contact with the three-way contact surfaces of the vibration-proof portion 14f or the vibration-proof portion 14r in advance.
In other words, it is sufficient that the predetermined elastic force can be ensured by contact when subjected to vibrations or impacts exceeding a predetermined level. For example, in the case of the second embodiment, the maximum distance between the fixed portion 101a or the fixed portion 101b is previously set. However, providing a gap of about 0.3 mm may improve the shock absorption.

Further, the height of the main body 13 (see FIG. 2) is added to the height of the vibration isolator 14f or the vibration isolator 14r so that the overall height of the apparatus does not increase. In order to make the electronic device 100 thin and to fix both by fixing the fixing portion 101b of the electronic device 100 to the surfaces of the vibration isolating portion 14f and the vibration isolating portion 14r that are lower than the surface Sa. Since it is not necessary to use a screw, a local fixing stress does not act, and a more uniform fixing stress can be obtained over the entire abutting surface. Since the impact resistance and vibration resistance of the carrier device 11 can be improved, higher reliability can be ensured.

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

The present invention is built in an electronic device including a mobile communication system such as a mobile system such as a personal media player, a mobile Internet device, a mobile phone, a portable videophone terminal, a PDA, and a micro PC, or an in-vehicle navigator system. It can be applied to a disk type record carrier driving device.
