Two hinge portions 5 are provided apart from each other at a connection portion between the PC main body 3 and the display portion 4.

  As shown in FIG. 3, the hinge portion 5 has a hinge cover 12 (cover body) that closes the opening 11 formed in the upper surface cover 3 a (main body housing, connection portion housing) of the PC main body 3. The hinge unit 5 has a function of connecting the display unit 4 to the PC main body 3 so as to be rotatable, and for passing a harness (wiring) (not shown) that connects the electronic components of the PC main unit 3 and the display unit 4. It also has a function as a duct.

  The hinge cover 12 has a shape in which a substantially cylindrical resin member is substantially halved along the axial direction thereof, and a latch claw 13 for engaging with the upper surface cover 3a is integrally formed on the end side thereof. Further, the hinge cover 12 has an engaging step portion 14 for engaging with the upper surface cover 3a on the side opposite to the latch claw 13. The hinge cover 12 secures a space for passing a harness (not shown) due to its curved shape.

  The top cover 3 a has an opening 11 for attaching the hinge cover 12, and the end surface on the rear side of the top cover 3 a is curved from the opening 11 toward the lower part of the PC main body 3. An engagement hole 15 for engaging the latch claw 13 of the hinge cover 12 is formed in this curved portion of the top cover 3a. The engagement hole 15 is formed through the upper surface cover 3a.

  The engagement hole 15 is formed at a position accessible from the rear side of the PC main body 3 and is formed so that a tool such as a screwdriver can be inserted in order to release the engagement state by the latch claw 13. In the present invention, the inner surface of the engagement hole 15 and the engagement surface for engaging the latch claw 13 are formed flush with each other.

  When the hinge cover 12 having the above structure is attached to the upper surface cover 3 a, the engagement step portion 14 is first engaged with the upper surface cover 3 a, and the latch claw 13 is engaged with the engagement hole 15. The latch claw 13 can close the engagement hole 15 so that the inside cannot be seen through the engagement hole 15 from the outside of the notebook PC 1 in the state shown in FIG. 2 in which the hinge cover 12 is attached to the upper surface cover 3a. Has a shape.

  When the latch claw 13 is removed from the engagement hole 15, a tool is inserted into the engagement hole 15 from the rear side of the notebook PC 1, and the latch claw 13 is pressed to release the engagement with the engagement hole 15. At this time, since the engagement surface with which the latch claw 13 is engaged and the inner surface of the engagement hole 15 are formed flush with each other, the engagement state can be easily released without the tip of the tool being caught.

  As described above, according to the present invention, when removing the hinge cover 12 from the top cover 3a of the PC main body 3, the latch can be released simply by inserting a dedicated tool from the back side of the notebook PC 1 into the engagement hole 15. In addition, since the latch claw 13 has a structure in which a part of the latch claw 13 closes the engagement hole 15 in a state where the latch claw 13 is engaged with the engagement hole 15, that is, with the hinge cover 12 attached, the engagement is performed from the outside of the notebook PC 1. The inside cannot be seen through the joint hole 15.

  Further, according to the present invention, since the engaging surface for engaging the latch claw 13 is formed flush with the inner surface of the engaging hole 15, it is necessary to form an engaging surface separately from the engaging hole 15. Therefore, the structure can be simplified and the apparatus configuration can be made compact. This also makes it possible to set the position of the engagement hole 15 relatively freely and improve the degree of freedom in design.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above.

  For example, in the above-described embodiment, the case where the present invention is applied to the hinge cover 12 of the hinge portion 5 in the connection portion between the PC main body 3 and the display unit 4 has been described. The present invention may also be applied to a cover of a duct that is provided separately from the hinge portion 5 at the connection portion and the upper surface cover 3a or the connection portion thereof and passes a harness (not shown) that connects the display portion 4 and the PC main body 3.

  In the above-described embodiment, the case where the present invention is applied to the notebook PC 1 has been described. However, the present invention is not limited to this, and the present invention can also be applied to other electronic devices such as a PAD.

  By the way, when the above structure is adopted as the cover structure of the electronic device, it is necessary to form the engagement hole 15 on the main body housing side to which the cover is attached. In particular, when the upper surface cover 3a of the PC body 3 is curved as in the present embodiment, it is necessary to devise when manufacturing the upper surface cover 3a having the engagement holes 15 using a mold. .

  In the present embodiment, as shown in FIG. 4, the engagement holes 15 are formed in the upper surface cover 3 a using two molds 21 and 22. That is, one mold 21 is disposed at a position where the opening 11 of the top cover 3a is formed, the other mold 22 is disposed at a position where the engagement hole 15 is formed, and the mold is filled with a resin material. After forming the upper surface cover 3a, the mold 21 was extracted upward (in the direction of arrow A in the figure), and the mold 22 was extracted out in the right direction (in the direction of arrow B in the figure).

  When manufacturing the upper surface cover 3a having the engagement hole 15 having the above structure, it becomes impossible to extract the mold in the direction other than the above, and thus the above manufacturing method is inevitably adopted. In this case, since it is necessary to extract the mold 22 for forming the engagement hole 15 in the direction of arrow B, it is necessary to form the engagement surface with which the latch claw 13 is engaged with the inner surface of the engagement hole 15. There is.

  In other words, according to the present invention, the engagement surface for engaging the latch claw 13 and the engagement hole for inserting the tool for releasing the engagement can be formed simultaneously in one process, thereby reducing the number of manufacturing steps. Manufacturing costs can be reduced.
