Electronic apparatus
View Patent ↗Buffer materials 7 and a lower principal surface 6 a of a hard disk case 6 , and the buffer materials 7 and a hard disk drive 5 , are adhesively fixed to each other by strong pressure-sensitive adhesive forces. Pressure-sensitive adhesive materials 8 are provided between the hard disk drive 5 and an upper principal surface 6 b of the hard disk case 6 . The pressure-sensitive adhesive force of each pressure-sensitive adhesive material 8 is weak to such a degree that the pressure-sensitive adhesive material 8 becomes detached by a contraction force of each buffer material 7 . Thus, when external disturbance is applied to the hard disk drive 5 , each pressure-sensitive adhesive material 8 becomes detached during contraction of each buffer material 7 . The contraction of each buffer material 7 and the detachment of each pressure-sensitive adhesive material 8 allow improvement of the impact resistance of the hard disk drive 5.
1. An electronic apparatus comprising:
a housing;
a component disposed within the housing;
a first buffer member disposed between a first surface of an inside of the housing and the component;
a second surface, of the inside of the housing, opposed to the first surface across the component;
a pressure-sensitive adhesive material disposed between the component and the second surface for positioning the component and the second surface, and
wherein a bonding between the pressure-sensitive adhesive material and the component or a bonding between the pressure-sensitive adhesive material and the second surface is broken when the first buffer member contracts such that a thickness of the first buffer member becomes a post-contraction length (T 4 ) from a natural length (T 1 ) ((T 1 )>(T 4 )).
2. The electronic apparatus according to claim 1 , further comprising a second buffer member interposed between the component and the second surface, wherein
at least either the second surface and the second buffer member or the second buffer member and the component are fixed to each other by the pressure-sensitive adhesive material.
3. The electronic apparatus according to claim 2 , wherein the component and the first buffer member, and the first buffer member and the first surface, are fixed to each other more firmly than by pressure-sensitive adhesiveness of the pressure-sensitive adhesive material.
4. The electronic apparatus according to claim 3 , wherein a buffer limit length F of the second buffer member in a stretching direction from a natural length of the second buffer member is shorter than a buffer enable length ((T 1 )−(T 4 )) of the first buffer member in a stretching direction from a natural length of the first buffer member.
5. The electronic apparatus according to claim 3 , wherein
the second surface and the second buffer member are fixed to each other by the pressure-sensitive adhesive material, and
the second buffer member and the component are fixed to each other more firmly than by the pressure-sensitive adhesiveness of the pressure-sensitive adhesive material.
6. The electronic apparatus according to claim 2 , wherein the first buffer member is formed so as to have a hardness lower than that of the second buffer member.
7. The electronic apparatus according to claim 2 , wherein
each of the first buffer member and the second buffer member has a plate shape with a predetermined thickness, and
the first buffer member is formed so as to have a thickness smaller than that of the second buffer member.
8. The electronic apparatus according to claim 2 , wherein a center of gravity of the electronic apparatus is located closer to the first surface than to the second surface.
9. The electronic apparatus according to claim 2 , wherein
the electronic apparatus is placed on a flat surface when being used, and
the second surface is located above the first surface in the used state.
10. The electronic apparatus according to claim 2 , wherein a portion of the first buffer member is located at a position where the portion of the first buffer member faces a portion of the second buffer member across the electronic apparatus.
11. The electronic apparatus according to claim 1 , wherein the pressure-sensitive adhesive material has re-adhesiveness.
