  FIG. 10 is an explanatory diagram showing the recording unit 10 and the elastic member 200 housed in the housing unit 8.

  As shown in the figure, the concavo-convex portions 241 and 251 provided at locations corresponding to the main surface 12 of the recording portion 10 of the elastic member 200 abut on the inner surface of the second housing portion 32 of the housing 30. Concave and convex portions 242 a, 242 b, and 252 provided at locations corresponding to the main surface 11 of the recording unit 10 abut on the inner surface of the first housing unit 31. More specifically, the concavo-convex portions 242a and 252 are in contact with the inner surface of the region where the input operation unit 7a of the first casing 31 is installed, and the concavo-convex portion 242b is an input operation of the first casing 31. It abuts on the area where the portion 7a is not installed, that is, the inner surface of the palm rest 7b. The concave and convex portions 243 and 253 provided at locations corresponding to the side surface 13 of the recording unit 10 abut on the side wall portion 51 of the frame member 50 as described above. Although not shown in the drawing, the concave and convex portions 244 and 254 are also in contact with the side wall portion 51 of the frame member 50 in the same manner.

  Further, in the elastic member 100, similarly to the elastic member 200, the uneven portions 140 and 150 are formed on the inner surface of the first housing portion 31, the inner surface of the second housing portion 32, and the side wall portion 51 of the frame member 50. Abut.

  With the configuration described above, the elastic members 100 and 200 are mounted in the three-axis direction of the rectangular parallelepiped with respect to the six surfaces of the recording unit 10 and the recording unit 10 is elastically in the three-axis direction with respect to the six surfaces of the storage unit 8. To support.

  As a result, the recording unit 10 elastically supported by the elastic members 100 and 200 can withstand an impact from the triaxial direction. That is, when the PC 1 receives an impact from the outside, each of the groove-like uneven portions 140, 150, 240, 250 having elasticity absorbs the impact by being distorted in the triaxial direction, and the recording portion 10 is protected from the impact. To do. Further, by giving elasticity to the elastic members 100 and 200, the elastic members 100 and 200 can be thinned and the space near the recording unit 10 can be reduced, so that the PC 1 can be thinned and miniaturized. .

  Further, as described above, the depth of the grooves of the concavo-convex portions 241 and 251 is larger than the depth of the grooves of the concavo-convex portions 242a and 252 and the thickness of the plate-like portions 211 and 221 is greater than the thickness of the plate-like portions 212 and 222. large. When the PC 1 is in a closed state, the first casing 31 is covered with the display unit 3, but the second casing 32 is exposed to the outside. When the PC 1 in this state receives an impact from the outside, the second casing 32 is more likely to receive a greater impact than the first casing 31. Therefore, by increasing the depth of the grooves of the concavo-convex portions 241 and 251, the concavo-convex portions 241 and 251 are more easily distorted and can absorb a larger impact. Here, when the uneven portions 241 and 251 are greatly distorted, the plate portions 211 and 221 may be damaged if the plate portions 211 and 221 are thin. Therefore, the plate-like portions 211 and 212 are made thick so that the plate-like portions 211 and 221 are prevented from being damaged and the protection performance of the recording unit 10 is improved.

  Furthermore, it is sufficient to use only the elastic members 100 and 200, which are integrally molded products, as members for supporting the recording unit 10 in the storage unit 8, and an attachment chassis and screws are unnecessary. Thereby, the number of parts can be reduced, the manufacturing cost can be reduced, and the workability at the time of attaching / detaching the recording unit 10 is improved.

  In addition, the storage unit 8 that stores the recording unit 10 includes a first casing unit 31 and a second casing unit 32 on the upper and lower surfaces. As a result, the PC 1 can be thinned.

[Accommodating structure of recording unit 20]

[Modification]
In the present embodiment, two concave portions (slits) are formed between the three convex portions in the groove-shaped concave and convex portions 341, 343, 342, 441, 443, and 442 of the elastic members 300 and 400. However, the present invention is not limited to this, and the uneven portion may be formed so that one slit is provided, or the uneven portion may be formed so that two slits are provided. Alternatively, the slit may not be formed depending on the material of the elastic member and the required robustness.

  FIG. 18 is a graph comparing the functions of elastic members each having a different number of slits.

  Here, an experiment was performed using an elastic member provided with two slits such as the elastic members 300 and 400, an elastic member without a slit, an elastic member provided with one slit, and an elastic member provided with three slits. It was. Elastic members were attached to the four corners of the 1.8-inch hard disk drive, and an acceleration sensor was attached to the center. Assuming that the PC is used on a desk, the recording unit was dropped from a height of 76 cm onto a carpeted floor. The drop experiment was performed five times, and the average of the gravitational acceleration (G value) at the time of the drop impact was determined.

  As shown in the figure, when the number of slits is increased, the G value at the time of drop impact decreases. That is, the larger the number of slits, the more easily the elastic member bends and absorbs larger impact energy. However, in some cases, if the elastic member bends too much, there is a risk of contacting each member inside the housing. Therefore, the number of slits may be determined in consideration of the material of the elastic member, the required cushion effect, the width and depth of the slits, and the like.

  The embodiment according to the present invention is not limited to the above-described embodiment, and various other embodiments are conceivable. For example, in this embodiment, the elastic member is used to support a recording unit such as a hard disk drive. However, the present invention is not limited to this, and this elastic member may be used to support a storage device such as a nonvolatile semiconductor memory or other members that are vulnerable to impact.

  The elastic members 100, 200, 300, and 400 are each formed of an elastic material such as a rubber material (JIS A 30 °). However, the present invention is not limited to this, and a rubber material having a different hardness or another elastic material may be used. What is necessary is just to change suitably the thickness, groove width, etc. of an uneven | corrugated | grooved part according to the material to be used.
