  A cable guide 37 for guiding the antenna cable 59 is formed below the bracket 62 on the rear wall portion 48A of the back cover 48. The cable guide 37 extends in the width direction of the display unit 40. With this cable guide 37, the antenna cable 59 is routed along the lower end 62T2 (see FIG. 6) of the bracket 62.

  As shown in FIG. 6, the hinge shaft 68 is rotatably supported by a hinge base 70 disposed on the center side in the width direction of the display unit 40 (see FIG. 1) relative to the hinge arm 66. The hinge base 70 as an example of a support portion includes a base plate 70A and a bearing portion 70B. The base plate 70A has a plurality of mounting holes 92 into which screws (not shown) for fixing the base plate 70A to the rear end of the first housing 22 (see FIG. 1) are inserted.

The guide portion 62B has a convex shape that protrudes toward the back side (arrow Z side) with respect to the fixed portion 62A by bending the bracket 62 along the extending direction (arrow Y direction) of the reinforcing frame 64. Is formed. By this guide portion 62B, a groove-like passage 63 extending from the lower end 62T2 to the upper end 62T1 of the bracket 62 is formed in the bracket 62.

  More specifically, as shown in FIG. 7, the guide portion 62 </ b> B is formed such that the cross-sectional shape along the width direction of the main body unit 20 is a C-shaped cross section that opens on the front side (front cover 46 side). And has a bottom wall 62B1 and two side walls 62B2 and 62B3. A groove-like passage 63 through which the antenna cable 59 and the like pass is formed in the guide portion 62B.

  Further, the guide portion 62B is located on the back side (the rear wall portion 48A side of the back cover 48) from the fixed portion 62A. Thus, when the fixing portion 62A of the bracket 62 is fixed to the boss portion 76A or the like protruding from the rear wall portion 48A of the back cover 48, the guide portion 62B is closer to the hinge arm 66 (see FIG. 6) side than the boss portion 76A or the like.

That is, the guide portion 62B is stored in the hinge storage portion 50 of the back cover 48 so as to be adjacent to the boss portion 76A and the like in the width direction of the display unit 40.

  The inner side wall 62B3 of the guide portion 62B constitutes the inner end of the bracket 62, and the hinge arm 66 (see FIG. 6) described above is raised from the side wall 63B to the front cover 46 side. . That is, the bracket 62 protrudes outward from the end of the back cover 48 on the rear wall 48 </ b> A side of the hinge arm 66. FIG. 7 is a cross-sectional view taken along line 7-7 in FIG. 1. The cross-sectional position shown in FIG. 7 corresponds to the line GG in FIG.

  Next, the wiring method of the antenna cable 59 will be described, and the operation of this embodiment will be described. Note that the wiring method of the camera cable 56 is the same as that of the antenna cable 59, and thus the description thereof is omitted.

  As shown in FIG. 5, the antenna cable 59 is routed to the hinge housing portion 50 through the outside of the reinforcing frame 64 of the hinge unit 60. The antenna cable 59 wired to the hinge storage unit 50 passes through the outside of the bracket 62 of the hinge unit 60 (arrow X side) while being guided by the cable guide 36, and goes around to the lower side of the bracket 62. The antenna cable 59 that wraps around to the lower side of the bracket 62 is wired to the lower surface 42D side of the display panel 42 through the passage 63 formed in the bracket 62 while being guided by the cable guide 37. In other words, the antenna cable 59 that has turned around to the lower side of the bracket 62 is guided to the upper side of the hinge base 70 (see FIG. 6) by the guide portion 62B. The antenna cable 59 wired to the display panel 42 side passes between the display panel 42 and the hinge arm 66, wraps around the hinge base 70 side of the hinge arm 66, and along the hinge arm 66 toward the hinge shaft 68 side. Wired. The antenna cable 59 wired to the hinge shaft 68 side is wired along the hinge shaft 68 and inserted from the opening 50A of the hinge housing portion 50 into the opening 34A of the hinge housing portion 34 of the first housing 22.

  Here, as a wiring method for wiring the antenna cable 59 from the outside of the reinforcing frame 64 to the hinge shaft 68 side, for example, the antenna cable 59 intersects the reinforcing frame 64 or the bracket 62 in the width direction of the display unit 40. It is possible to make it. In this case, since a space for wiring the antenna cable 59 is required between the reinforcing frame 64 and the front cover 46 or between the fixing portion 62A of the bracket 62 and the front cover 46, the thickness of the display unit 40 is reduced. May increase.

  Further, for example, it is conceivable to form a groove or a hole through which the antenna cable 59 passes in the width direction of the display unit 40 with respect to the reinforcing frame 64. In this case, when the display unit 40 is opened / closed with respect to the main unit 20 (see FIG. 1), the reinforcing frame 64 may be broken at a portion where a groove or a hole is formed. That is, if a groove or a hole for passing the antenna cable 59 in the width direction of the display unit 40 is formed in the reinforcing frame 64, the rigidity of the reinforcing frame 64 against bending in the front-rear direction of the display unit 40 may be reduced. Garage. Therefore, there is a possibility that the bending deformation of the second housing 44 accompanying the opening / closing operation of the display unit 40 becomes large.

  Similarly, if a groove or hole for passing the antenna cable 59 in the width direction of the display unit 40 is formed in the bracket 62, the rigidity of the reinforcing frame 64 against bending in the front-rear direction of the display unit 40 decreases. there is a possibility. Further, when a groove or hole for passing the antenna cable 59 is formed in the width direction of the display unit 40 with respect to the bracket 62, the fixing strength of the bracket 62 to the boss portion 76A provided on the back cover 48 is high. May be reduced.

  On the other hand, in this embodiment, as shown in FIG. 7, the guide portion 62 </ b> B has a convex shape that is convex toward the back surface with respect to the fixing portion 62 </ b> A of the bracket 62. Further, the guide portion 62 </ b> B extends in the extending direction of the reinforcing frame 64. In other words, the guide portion 62B extends in a direction intersecting (in the present embodiment, orthogonal) with the axis J of the hinge shaft 68. Thereby, the rigidity of the bracket 62 with respect to the bending of the display unit 40 in the front-rear direction (rotation direction) is higher than that of a flat bracket without the guide portion 62B. Furthermore, the fixing strength of the bracket 62 with respect to the boss portion 76A and the like provided on the back cover 48 is increased. Therefore, the bending deformation of the second housing 44 accompanying the opening / closing operation of the display unit 40 is suppressed.

  Further, the guide portion 62B is located on the back side (the rear wall portion 48A side of the back cover 48) with respect to the fixing portion 62A of the bracket 62. Therefore, when the fixing portion 62A of the bracket 62 is fixed to the boss portion 76A or the like protruding from the rear wall portion 48A of the back cover 48, the guide portion 62B is adjacent to the boss portion 76A or the like in the width direction of the display unit 40. Be placed. Accordingly, the antenna cable 59 can be wired so as to be adjacent to the boss portion 76A or the like in the width direction of the display unit 40. Accordingly, a space for wiring the antenna cable 59 between the fixing portion 62A of the bracket 62 and the front cover 46 is not necessary, so that the second housing 44 can be thinned.

Further, as shown in FIG. 8A, in the hinge unit 60 according to the present embodiment, a guide portion 62 </ b> B is formed at a portion between the fixing portion 62 </ b> A and the hinge arm 66 in the bracket 62. Therefore, the height from the fixed portion 62A of the bracket 62 to the axis line J of the hinge shaft 68 is _{H 1.} On the other hand, FIG. 8B shows a hinge unit 100 that does not include the guide portion 62B as a comparative example. The hinge unit 100 has a height from the fixed portion 62A of the bracket 62 to the axis line J of the hinge shaft 68 is _{H 2.} In other words, the height _{H 1} of the hinge unit 60 according to the present embodiment is lower than the height _{H 2} of the hinge unit 100 according to the comparative example _{(H 2>} H 1). Therefore, the thickness of the second housing 44 can be further reduced.

  Next, a modification of the hinge unit according to the above embodiment will be described.

  In the above-described embodiment, the guide portion 62B has a convex shape that protrudes toward the back surface with respect to the fixed portion 62A. However, the shape of the guide portion 62B is not limited thereto. For example, the guide portion 62B may be formed in a step shape.

  Specifically, as shown in FIG. 9, the guide portion 62B has an L-shaped cross section along the width direction of the main unit 20, and has a bottom wall 62B1 and a side wall 62B2. Yes. The bottom wall 62B1 is located on the back side (the rear wall portion 48A side of the back cover 48) with respect to the fixing portion 62A of the bracket 62. By this guide portion 62B, a passage 96 through which the antenna cable 59 and the like pass is formed closer to the rear wall portion 48A of the back cover 48 than to the fixing portion 62A of the bracket 62. Accordingly, a space for wiring the antenna cable 59 between the fixing portion 62A of the bracket 62 and the front cover 46 is not necessary, so that the second housing 44 can be thinned.

  Further, even if the guide portion 62B has a stepped shape, the rigidity of the bracket 62 with respect to bending in the front-rear direction of the display unit 40 is higher than that of a flat plate-like bracket that does not include the guide portion 62B. Further, the fixing strength of the bracket 62 to the boss portions 76A and 76B provided on the back cover 48 is increased. Therefore, the bending deformation of the second housing 44 accompanying the opening / closing operation of the display unit 40 is suppressed.

  In the above-described embodiment, the guide portion 62B is formed at a portion of the bracket 62 between the hinge arm 66 and the fixed portion 62A. However, the position of the guide portion 62B with respect to the bracket 62 is not limited to this. For example, as shown in FIGS. 10 and 11, a guide portion 62 </ b> B (passage 98) may be formed in a portion of the bracket 62 between the fixing portion 62 </ b> A and the reinforcing frame 64.

  In the above embodiment, the bracket 62 and the reinforcing frame 64 are integrally formed. However, the bracket 62 and the reinforcing frame 64 may be separated. When the bracket 62 and the reinforcing frame 64 are separated from each other, for example, it is conceivable to fix the lower end portion of the reinforcing frame 64 to the boss portions 76A and 76B provided on the back cover 48 with screws 74A and 74B. It is also possible to fix the lower end of the reinforcing frame 64 to the bracket 62 with screws or the like.

  Further, in the above embodiment, the notebook computer 10 has been described as an example of the electronic apparatus. However, the above embodiment can be applied to an electronic apparatus such as a mobile phone, a portable DVD player, and an electronic dictionary. is there.

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