The bottom surface portion 23 is provided on most of the rear portion 9 a of the lower wall 9 and a part of the front portion 9 b, and forms the largest area in the lower wall 9. That is, the bottom surface part 23 forms the main part of the lower wall 9.

  As shown in FIG. 3, the bottom surface portion 23 has a main surface 27 and an inclined surface 28. The main surface 27 is formed on the rear portion 9 a of the lower wall 9. The main surface 27 extends, for example, in parallel with the upper wall 7. That is, when the upper wall 7 is in a horizontal posture, the main surface 27 spreads horizontally.

  As shown in FIG. 5, the HDD 6 is disposed with a slight gap between the inner surface of the lower wall 9 (unit facing region 24), for example. For example, the HDD 6 is placed on a rubber member 29 attached to the inner surface of the unit facing region 24.

  As shown in FIG. 3, the inclined surface 28 is provided on the front portion 9 b of the lower wall 9. The inclined surface 28 is, for example, between the left side wall portion 8c and the unit facing region 24, between the unit facing region 24 and the recessed portion 25, between the recessed portion 25 and the right side wall portion 8d, and the unit facing region 24. Further, it is formed between the depression 25 and the main surface 27. The inclined surface 28 is inclined with respect to the HDD 6 (that is, with respect to the upper wall 7). That is, when the upper wall 7 is in a horizontal posture, the inclined surface 28 is inclined with respect to the horizontal. The inclined surface 28 is inclined so that the thickness of the casing 5 becomes thinner as it goes away from the rear end portion 5a of the casing 5.

  As shown in FIG. 4, the unit facing region 24 is recessed inside the housing 5 from the inclined surface 28. The unit facing area 24 extends in parallel with the HDD 6 (that is, in parallel with the upper wall 7). That is, when the upper wall 7 is in a horizontal posture, the unit facing region 24 extends horizontally.

  As shown in FIG. 3, the bottom surface portion 23 has first to third portions 31, 32, 33. The first portion 31 is provided between the left side wall portion 8 c and the unit facing region 24. The second portion 32 is provided between the unit facing region 24 and the recessed portion 25. The third portion 33 is provided between the recessed portion 25 and the right side wall portion 8d.

  That is, the first and second portions 31 and 32 sandwich the unit facing region 24 therebetween. The third portion 33 is adjacent to the unit facing region 24 from a direction different from that of the first and second portions 31 and 32. That is, the unit facing region 24 is surrounded by the bottom surface 23 in a U shape from three directions. The unit facing region 24 has a stepped portion 36 between the unit facing region 24 and the bottom surface portion 23. The first to third portions 31, 32, and 33 have bottom surfaces 31a, 32a, and 33a that are inclined surfaces 28, respectively.

  The unit facing region 24 includes a flat portion 34 (horizontal portion) that extends in parallel with the HDD 6 and a bulging portion 35 that bulges toward the outside of the housing 5. The flat portion 34 is formed in a region outside the bulging portion 35 in the unit facing region 24. The bulge portion 35 is provided, for example, at the center of the unit facing region 24 and covers the lower portion of the HDD 6. The bulging part 35 swells in an elliptical dome shape, for example. The bulging portion 35 swells in a direction perpendicular to the flat portion 34.

  As shown in FIGS. 6 and 7, the bulging portion 35 is located inside the housing 5 with respect to the inclined surface 28. That is, when the housing 5 is viewed from the side (for example, when the left side wall portion 8c of the housing 5 is viewed from the front), the outer peripheral portion of the bulging portion 35 does not protrude from the projected line of the inclined surface 28.

  More specifically, as shown in FIG. 7, the bulging portion 35 has a virtual plane P (the left side wall of the housing 5) connecting the bottom surface 31 a of the first portion 31 and the bottom surface 32 a of the second portion 32 of the bottom surface portion 23. In the state when 8c is viewed from the front, it is within the housing 5 than the line of the bottom surface 31a). More specifically, the bulging portion 35 according to the present embodiment is a housing than the virtual plane P connecting the bottom surface 31a of the first portion 31, the bottom surface 32a of the second portion 32, and the bottom surface 33a of the third portion 33. 5 is inside.

  As shown in FIG. 7, the unit facing region 24 further has a second bulge portion 37. As shown in FIG. 3, the second bulge portion 37 is provided between the edge portion (front edge portion) of the unit facing region 24 on the side opposite to the display portion 3 and the bulge portion 35. The second bulge portion 37 extends in the width direction of the housing 5 along the front edge of the unit facing region 24, and is provided over the entire width of the unit facing region 24. The second bulge portion 37 is a slight bulge, and bulges smaller than the above-described bulge portion 35 (first bulge portion) toward the outside of the housing 5.

Next, the operation of the portable computer 1 will be described.
The portable computer 1 has a bulging portion 35 in an area covering the spindle portion 6 a of the HDD 6. Thereby, even if an impact is applied to the lower wall 9, the bulging portion 35 functions as a buffer portion, and the impact is not directly transmitted to the spindle portion 6a. Thereby, the HDD 6 is not easily damaged, and the reliability of the portable computer 1 is improved.

  FIG. 8 shows a state in which the front leg portion 21 of the housing 5 is detached (dropped) from the placement surface S. In this state, the lower wall 9 of the housing 5 is in direct contact with the placement surface S. In the portable computer 1 according to the present embodiment, the bulging portion 35 is located inside the housing 5 with respect to the inclined surface 28. Therefore, even if the lower wall 9 comes into direct contact with the placement surface S, the inclined surface 28 of the bottom surface portion 23 is in contact with the placement surface S, and the bulge portion 35 is not in contact with the placement surface S. That is, the bulging part 35 is not pushed by the mounting surface S. As a result, vibration and impact are not easily transmitted to the HDD 6, and the HDD 6 is not easily damaged.

  According to the portable computer 1 having such a configuration, the impact resistance is improved. That is, by providing the bulging portion 35, even if the gap between the lower wall 9 and the HDD 6 is reduced, a load (impact) is not easily applied to the HDD 6 and the HDD 6 is not easily damaged. Thereby, the thickness of the device can be reduced, and the impact resistance of the HDD 6 can be ensured.

  Furthermore, when the bulging portion 35 is positioned inside the housing 5 with respect to the inclined surface 28 of the bottom surface portion 23, the bulging portion 35 is mounted even when the leg 21 on the front side of the housing 5 is detached from the placement surface S, for example. It is not pushed by the mounting surface S. That is, when the front leg 21 of the housing 5 is detached from the mounting surface S, it is difficult to apply a load (impact) to the HDD 6 and the HDD 6 is not easily damaged. Thereby, the impact resistance of the portable computer 1 is realized at a higher level.

  When the unit facing area 24 is recessed inward of the housing 5 from the inclined surface 28 of the bottom surface portion 23 and extends in parallel with the HDD 6, the HDD 6 mounted in a posture inclined with respect to the inclined surface 28 of the bottom surface portion 23 is mounted. Easy to support. For example, when the HDD 6 is placed in a posture parallel to the upper wall 7, the HDD 6 is less susceptible to vibrations when the portable computer 1 is carried.

  In other words, the housing 5 according to the present embodiment is configured so that the housing 5 having the inclined surface 28 on the bottom surface portion 23 faces the unit that is recessed with respect to the inclined surface 28 in order to support the HDD 6 in parallel with the upper wall 7. A bulge portion 35 that has an area 24 and improves the impact resistance of the HDD 6 is provided by utilizing the difference in height between the recessed unit facing area 24 and the inclined surface 28.

  When the bulging part 35 covers the lower part of the spindle part 6a of the HDD 6, the impact resistance of the HDD 6 is easily improved. If the bulging portion 35 has an elliptical shape, it can correspond to various HDDs 6 having different spindle positions.

  When the bulging portion 35 is formed in a dome shape, the bulging portion 35 can be easily placed inside the housing 5 with respect to the inclined surface 28. Further, when the bulging portion 35 swells in a dome shape, the impact applied to the HDD 6 can be further alleviated, and the impact resistance of the HDD 6 is easily improved.

  If the inclined surface 28 is inclined so that the thickness of the casing 5 becomes thinner as it moves away from the rear end portion 5a of the casing 5, the keyboard 17 can be disposed on the front side, and the portable computer 1 Improved operability. That is, in the present embodiment, in order to improve such operability, the inclined surface 28 provided on the bottom surface portion 23 is used to improve the impact resistance with respect to the HDD 6.

  When the unit facing region 24 is surrounded by the bottom surface portion 23 from three directions, for example, when the leg portion 21 is detached from the placement surface S, the bottom surface portion 23 comes into contact with the placement surface S and reliably supports the housing 5. In addition, the possibility that the unit facing area 24 contacts the placement surface S is reduced. This contributes to the impact resistance of the portable computer 1.

  When the unit facing region 24 has a second bulging portion 37 that is provided between the edge of the unit facing region 24 and the bulging portion 35 and bulges smaller than the bulging portion 35 toward the outside of the housing 5, The peripheral portion of the bulging portion 35 can be separated from the HDD 6. Thereby, when the bulging part 35 is pushed, it becomes difficult to apply force also to the periphery of the spindle part 6a, and the impact resistance of the HDD 6 is improved.

  The portable computer 1 according to one embodiment of the present invention has been described above, but the present invention is not limited to these. The components according to each embodiment can be implemented in appropriate combination. Further, the present invention can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  Note that “parallel” in the present invention (this specification) is not limited to parallel in a strict sense, and allows a certain amount of width. That is, the term “parallel” in the present invention (this specification) includes the case of “substantially parallel”.
