Dampers 15 and 16 using a rubber material as a second buffer member are attached to both side portions 10a and 10b of the battery pack 10. The dampers 15 and 16 may be made of an elastic material such as silicone.
[0017]
Since the dampers 15 and 16 have the same structure, the damper 15 will be described as an example. The damper 15 is formed in a substantially rectangular parallelepiped and has a thickness greater than that of the battery pack 10. A groove 15e is formed in the longitudinal direction substantially at the center of the damper 15. The damper 15 has an upper portion 15a, a lower portion 15b, and side portions 15c and 15d (the side portion 15d is not shown) so as to have a U-shaped cross section, thereby defining a groove 15e.
[0018]
Both side portions 10 a and 10 b of the battery pack 10 are held in the main body 2 by being inserted into the grooves 15 e and 16 e of the dampers 15 and 16. The battery pack 10 can be moved or vibrated in the three-dimensional direction of the front, rear, left, right, up and down by the dampers 15, 16, and when an impact is applied to the main body 2, the impact is not directly applied to the battery pack 10.

[0019]
FIG. 3 is a cross-sectional view taken along a cross-sectional line AA ′ of FIG.
[0020]
A circuit board 17 is mounted on the main body 2 via a boss 2a. On the circuit board 17, the HDD 4 to which the dampers 8 and 9 are attached is mounted. The HDD 4 to which the dampers 8 and 9 are attached and the circuit board 17 have substantially the same plane size. Further, a gap is provided between the HDD 4 and the circuit board 17 by the lower portions 8 b and 9 b of the dampers 8 and 9.
[0021]
A battery pack 10 to which dampers 15 and 16 are attached is mounted on the upper surface of the HDD 4. The battery pack 10 to which the dampers 15 and 16 are attached is mounted on the upper surface 4a of the HDD 4 between the upper portions 8a and 8b of the dampers 8 and 9. That is, the lower portions 15 b and 16 b of the dampers 15 and 16 are arranged on the upper surface of the HDD 4. Accordingly, a gap L1 corresponding to the thickness of the lower portions 15b and 16b of the dampers 15 and 16 is provided between the battery pack 10 and the HDD 4.
[0022]
Therefore, even when an impact is applied to the main body 2, the gap L1 allows the HDD 4 and the battery pack 10 to move in a three-dimensional direction and prevent them from colliding with each other. Needless to say, based on the elastic modulus and thickness of the materials of the dampers 8 and 9 and the dampers 15 and 16, a gap that does not collide even when the HDD 4 and the battery pack 10 vibrate at maximum may be designed.
[0023]
FIG. 4 is a cross-sectional view showing the relationship between the battery pack and the HDD when the battery pack expands. The battery pack 10 may expand due to aging or temperature rise. Even if the battery pack 10 expands as shown in FIG. 4, the gap L <b> 1 in FIG. 3 exists, so that the gap L <b> 2 is maintained without contacting the HDD 4. Even if the battery pack 10 expands, the gap L2 exists, and even if the HDD 4 and the battery pack 10 vibrate, they do not collide with each other and are not damaged.
[0024]
FIG. 5 shows a sectional view of an electronic apparatus according to the second embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0025]

That is, the dampers 15 and 16 of the battery pack 10 are mounted on the upper surfaces of the dampers 8 and 9 of the HDD 4. With this configuration, the gap L3 between the HDD 4 and the battery pack 10 is the sum of the thicknesses of the upper part 8a of the damper 8 and the lower part 15b of the damper 15, and is larger than the gap L1 in the first embodiment. Will be formed. In this case, the thickness of the main body 2 according to the second embodiment is larger than that of the first embodiment, but the second buffer member is overlaid on the first buffer member. Thus, compared to the first embodiment, there is an effect that it is possible to greatly absorb the external impact on the HDD 4 and the battery pack 10.
[0026]
