  As shown in FIG. 12, the distance L3 between the distal end portion 270A of the other end side protruding piece 270 of the bracket 250 and the elastic rib 150 is set to be narrower than the gap L1 of the moving space 116. (L3 <L1).

  Next, attaching and detaching operations of the HDD unit 200 to the housing unit 100 will be described with reference to FIGS. As described above, the HDD unit 200 is attached and removed by turning the notebook PC 10 upside down, that is, with the lower wall (bottom surface) 24D of the main body housing 24 facing upward. Therefore, the lower wall (bottom surface) 24D side is illustrated in the upper direction and will be described. Also, the attachment and removal operations are performed in a state where the bracket 250 is fixed to the HDD unit 200. In other words, the HDD unit 200 and the bracket 250 are integrated to perform attachment and removal operations. Also, the lid member 90 (see FIG. 3) that covers the opening 102 is removed in advance before the work, and is attached when the work is completed.

  First, an operation for attaching the HDD unit 200 to the housing unit 100 will be described.

  As shown in FIGS. 7 and 10, the HDD unit 200 has the other side surface 206 on the lower side, and as shown by an arrow F1 (see FIG. 10), the HDD unit 200 is accommodated from the side 206 side. 100 (opening 102). Then, the other end side protruding piece portion 270 of the bracket 250 is inserted into the insertion hole 106 of the housing portion 100 from obliquely above. At this time, the distal end portion 270A of the other end side protruding piece portion 270 hits the elastic rib 150, and the elastic rib 150 is bent and elastically deformed.

  As shown by an arrow K1 (see FIG. 10), the side surface portion 204 on one side of the HDD unit 200 is moved with the other end side protruding piece portion 270 of the bracket 250 inserted into the insertion hole 106 of the housing portion 100. Rotate down. Then, as shown in FIGS. 8 and 11, the one end side protruding piece 260 of the bracket 250 is placed on the shelf 120. In addition, this causes the other end side protruding piece 270 of the bracket 250 to be placed on the recess 132 of the shelf 130 while being inserted into the insertion hole 106.

  The HDD unit 200 is slid (moved) to one side (arrow Y1) as shown in FIGS. 8 and 9, 11 and 12, and the male unit of the HDD unit 200 is shown as shown in FIGS. The connector 212 is connected to the female connector 112 of the housing unit 100. As the HDD unit 200 slides (moves), the other end side protruding piece 270 of the bracket 250 slides (moves) on the concave portion 132 of the shelf 130 to one side and comes out of the insertion hole 106.

  The bracket 250 is fixed to the shelf portion 120 through the screw 92 in the notch portion 262 of the one end side protruding piece portion 260, and is fixed to the shelf portion 130 through the screw hole 272 in the other end side protruding piece portion 270 through the screw 94. As shown in FIGS. 10 to 12, the screw 92 may be temporarily fixed.

  In this manner, the HDD unit 200 is attached to the housing unit 100, and the male connector 212 of the HDD unit 200 is connected to the female connector 112 of the housing unit 100, so that the HDD unit 200 and the main unit 14 are electrically connected. Connected.

  Next, an operation for removing the HDD unit 200 from the housing unit 100 will be described. In addition, since it is a procedure reverse to the attachment work, the description is omitted as appropriate.

  As shown in FIGS. 9 and 12, the screws 92 and 94 are loosened and removed, the fixing of the bracket 250 to the housing portion 100 is released, and the HDD unit 200 is slid (moved) to the other side (arrow Y2). The screws 92 need only be loosened and not removed.

  As shown in FIGS. 8 and 11, the male connector 212 of the HDD unit 200 is pulled out from the female connector 112 of the housing portion 100 to release the connection. As the HDD unit 200 slides (moves), the one end side protruding piece 260 of the bracket 250 slides on the shelf 120 to the other side. Further, the other end side protruding piece portion 270 of the bracket 250 slides (moves) on the other side of the concave portion 132 of the shelf portion 130 and is inserted into the insertion hole 106. At this time, the distal end portion 270A of the other end side protruding piece portion 270 hits the elastic rib 150, and the elastic rib 150 is bent and elastically deformed.

  As shown in FIGS. 7 and 10, as shown by an arrow K2 (see FIG. 10), the side surface portion 204 on one side of the HDD unit 200 is rotated upward. Then, as indicated by an arrow F2 (see FIG. 10), the HDD unit 200 is pulled out and the HDD unit 200 is removed.

  Next, functions and effects of the present embodiment will be described.

  In attaching and detaching the HDD unit 200 to / from the housing portion 100, the other end side protruding piece portion 270 of the bracket 250 is inserted into the insertion hole 106 (see FIGS. 6, 10, 11, etc.). Thereby, the other end side protruding piece portion 106 of the bracket 250 can move to the other side (outside) of the accommodating portion 100. Therefore, the other end 102A of the opening 102 can be moved to one side by the amount that the other end side protruding piece 270 of the bracket 250 is inserted into the insertion hole 106. That is, compared with a configuration in which the insertion hole 106 is not provided at the other end portion of the housing portion 100, the opening area of the opening portion 102 of the housing portion 100 can be reduced, and as a result, the opening portion 102 is covered. The lid member 90 can be reduced in size.

  Further, by downsizing the cover member 90, the arrangement space of the components on the lower wall (bottom surface) 24D of the main body casing 24 is increased. As a result, the degree of freedom in designing the layout of the components on the lower wall (bottom surface) 24D is increased. improves. In the present embodiment, the leg portion 58D is provided in an arrangement space secured by downsizing the lid member 90 (see FIG. 8).

  Further, at the time of attaching and removing the HDD unit 200, the distal end portion 270A of the other end side protruding piece portion 270 of the bracket 250 hits the elastic rib 150, and the elastic rib 150 is bent and elastically deformed. Thereby, the impact on HDD unit 200 via bracket 250 is buffered.

  In particular, when the HDD unit 200 is removed, the HDD unit 200 suddenly slides to the other side at the moment when the male connector 212 of the HDD unit 200 is pulled out of the female connector 112 of the housing unit 100. And the other end side protruding piece part 270 may abut against the elastic rib 150 in a state where the momentum is increased. However, as described above, since the elastic rib 150 is elastically deformed, even if the other end side protruding piece portion 270 hits the elastic rib 150 in a state of increasing momentum, the shock to the HDD unit 200 is buffered. .

  Further, in the present embodiment, the bracket 250 has a through hole 240 formed in the center portion and concave portions 242 and 244 formed therein. Therefore, for example, there is no through-hole 240 and recesses 242, 244, and the impact buffering performance of the bracket 250 itself is improved as compared with the case where these portions are sheet metal.

  In the present embodiment, the shape of the elastic rib 150 viewed in the thickness direction is a trapezoid whose tip side is narrower than the base side. Accordingly, for example, the elastic rib 150 is more easily elastically deformed than the rectangular elastic rib, so that the shock absorbing performance of the elastic rib 150 is improved.

  As described above, in the present embodiment, the shock absorbing performance of the bracket 250 and the shock absorbing performance of the elastic rib 150 are improved, so that the shock to the HDD unit 200 is further buffered.

  The interval L3 between the tip 270A of the other end piece 270 of the bracket 250 and the elastic rib 150 is set to be narrower than the gap L1 of the moving space 116 (L3 <L1). Therefore, it is avoided that the side surface portion 206 on the other side of the HDD unit 200 hits the side wall 114 on the other side of the mounting portion 110 before the tip end portion 270A of the other end side piece portion 270 of the bracket 250 hits the elastic rib 150. The

  Further, in the present embodiment, the male connector 212 of the HDD unit 200 is slid by sliding the one end side protruding piece portion 260 and the other end side protruding piece portion 270 of the bracket 250 on the shelf portions 120 and 130. It connects with the female connector 112 of the accommodating part 100. FIG. Therefore, for example, the connection work is easier than when the connector is connected while holding the HDD unit 200 by hand and adjusting the height.

  Here, the comparative example shown in FIG. 13 will be described.

  In the comparative example shown in FIG. 13, a sheet metal bracket 950 on which one end side protruding piece portion 960 and the other end side protruding piece portion 970 are formed is fixed to the bottom surface 202 of the HDD unit 200. Then, the one end side protruding piece portion 960 of the bracket 950 is screwed to the shelf portion 920 and the other end side protruding piece portion 970 is screwed to the shelf portion 930.

  In the comparative example, the shelf portion 930 at the other end of the housing portion 900 is moved so that the one-end-side protruding piece portion 960 moves as in the mounting portion 110 (see FIG. 12 and the like) of the present embodiment. An allowance L4 is provided. Therefore, the other end 902A of the opening 902 of the accommodating portion 900 of the comparative example is located on the other side of the other end 102A (see FIG. 8) of the opening 102 of the accommodating portion 100 of the present embodiment. become. Therefore, the opening area of the opening 902 is increased accordingly, and as a result, the lid member (not shown) is enlarged.

  Therefore, as can be seen by comparing FIG. 8 and FIG. 13, in this embodiment, the leg portion 58D provided in the arrangement space secured by downsizing the lid member 90 cannot be provided in the comparative example. Yes. For this reason, for example, it is necessary to form a convex portion 928 instead of the leg portion at the end of the lower wall (bottom surface) 924D of the main body casing 24. Thus, for example, the balance with the other legs 58A, 58B, 58C is lost.

  On the other hand, in this embodiment, as described above, the leg portion 58D similar to the other leg portions 58A, 58B, 58C is desired in the arrangement space secured by downsizing the lid member 90. The position can be well balanced.

  In the comparative example, when the HDD unit 200 is attached and detached, the distal end portion 970 </ b> A of the other end side protruding piece portion 970 of the bracket 950 hits the vertical wall 912 at the back of the shelf portion 930 in the accommodating portion 900. Therefore, an impact is applied to the HDD unit 200 via the bracket 950.

  On the other hand, in the present embodiment, as described above, even if the distal end portion 270A of the other end side protruding piece portion 270 hits the elastic rib 150, the elastic rib 150 is bent and elastically deformed. Therefore, the impact on the HDD unit 200 via the bracket 250 is buffered.

  Further, the bracket 950 of the modified example is not formed with the through-hole 240 and the recesses 242 and 244 as in the present embodiment (see FIG. 8 and FIG. 13 for comparison). Therefore, the bracket 950 of the modified example has a lower shock absorbing performance than the bracket 250 of the present embodiment, so that the shock to the HDD unit 200 is further buffered in this embodiment from this viewpoint.

  As mentioned above, although one Embodiment of the technique which this application discloses was described, the technique which this application discloses is not limited to the said embodiment.

  For example, in the above embodiment, in the state where the HDD unit 200 is mounted on the mounting portion 110 and the female connector 112 and the male connector 212 are connected, the other end side protruding piece portion 270 of the bracket 250 is inserted into the insertion hole 106. (See FIGS. 9 and 12). However, it is not limited to this. Even when the HDD unit 200 is mounted on the mounting portion 110 and the female connector 112 and the male connector 212 are connected, the distal end portion of the other end side protruding piece portion 270 of the bracket 250 is inserted into the insertion hole 106. May be.

  Further, for example, in the above-described embodiment, the other-end-side protruding piece 270 and the insertion hole 106 are provided one by one, but the present invention is not limited to this. A plurality of insertion holes corresponding to the other end side protruding piece portions may be provided.

  Further, for example, an insertion hole (insertion port) into which the one end side protruding piece 260 of the bracket 250 can be inserted is provided at one end of the housing 100, and the opening area of the opening of the housing is reduced. Then, the lid member may be further downsized.

  In the said embodiment, although the buffer member was the elastic rib 150 of the cantilever structure, it is not limited to this. The buffer member may be a wall made of an elastic member such as rubber, for example. Furthermore, the structure without a buffer member may be sufficient.

  Moreover, in the said embodiment, although the electronic unit was the HDD unit 200, it is not limited to this. The electronic unit may be another auxiliary storage medium such as an SSD (Solid state drive). Or a battery (secondary power supply), a battery pack, etc. may be sufficient.

  Moreover, in the said embodiment, although the electronic device was what is called notebook PC10, it is not limited to this. For example, a so-called integrated personal computer or a so-called tablet personal computer in which a display or a keyboard is integrated may be used. Furthermore, the present invention may be applied to electronic devices other than personal computers.

  In the present embodiment, the opening 102 is provided in the lower wall (bottom surface) 24D of the main body casing 24, but the present invention is not limited to this. For example, in the case of an integrated personal computer or tablet personal computer, an opening may be provided on the back of the screen. In the case of an electronic device other than a PC, an opening may be provided as appropriate.

  Furthermore, it goes without saying that the technology disclosed in the present application can be implemented with various modifications within a range not departing from the gist thereof.
