  FIG. 4 is a cross-sectional view at the Z2-Z2 cross-sectional position of FIG. FIG. 5 is a perspective view showing a portion where the fan is arranged in the rear side housing of the second housing in a state where the cable guide sheet is not bent.

  As shown in FIGS. 2, 4, and 5, the vertical wall portion 102 c is formed on the inner surface of the upper surface portion 102 u of the upper housing 102 </ b> A so as to protrude into the internal space SP (SP1 and SP2) of the second housing 102. Is erected. The vertical wall portion 102c divides the internal space SP of the second housing 102 into a main space SP1 in which the circuit board 410 and the fan device 500 are disposed, and a battery housing space SP2 in which the battery 460 is detachably housed. .

  In the main space SP1, cables 431 and 432 for connecting the power connector 430 and the circuit board 410 and a cable 433 for connecting the speaker 440 and the circuit board 410 are accommodated. Each of the cables 431, 432, and 433 includes a metal core wire and a covering material that covers the core wire. The covering material is made of, for example, a resin having flexibility and elasticity, and the cables 431, 432, and 433 can be wired in a bent state.

  The wiring of the cables 431, 432, and 433 will be described in more detail. The cables 431, 432, and 433 are wired using a gap portion in which no components are arranged in the main space SP1, and according to the shape of the gap. Is bent. The cables 431, 432, and 433 in the bent state tend to be deformed in a direction in which the bending is relaxed by the restoring force due to the elasticity of the resin covering material. Therefore, even if wiring is performed so as to fit within the gap, the cables 431, 432, and 433 may protrude from the gap over time. In order to prevent this, the computer 100 according to the present embodiment employs the following configuration.

  As shown in FIGS. 2 and 4, in the fan device 500, cables 431 to 433 are wired between the vertical wall portion 102c of the upper housing 102A and the side surface portion 501b of the fan device 500 facing the vertical wall portion 102c. It arrange | positions so that the clearance gap AS to be formed may be formed.

  As shown also in FIG. 3, protrusions 501e and 501f extending toward the vertical wall portion 102c of the upper housing 102A are provided on the side surface portion 501b of the fan case 501 of the fan device 500.

  One end side of the cable guide sheet 600 is fixed to the vertical wall portion 102c of the upper housing 102A. The cable guide sheet 600 is configured using a resin-made sheet material having flexibility and elasticity. The portion of the cable guide sheet 600 that is fixed to the vertical wall portion 102c of the upper housing 102A is hereinafter referred to as a vertical surface portion 600a (one end side portion) as appropriate. The vertical surface portion 600a is attached to the vertical wall portion 102c of the upper housing 102A using, for example, an adhesive.

  Here, as shown in FIGS. 5 and 6, the cable guide sheet 600 has a planar shape with an I-shaped cross section due to elasticity in the initial state. 6 is a cross-sectional view at the same cross-sectional position as FIG. 4 in a state where the cable guide sheet is not bent.

  As shown in FIGS. 2 and 4, the cable guide sheet 600 includes cables 431 to 433 in which a portion 600b on the other end side (hereinafter referred to as “lateral surface portion 600b” as appropriate) is wired in the gap passage AS. Is bent in an L-shaped cross section so as to cover from the opposite side. In the bent state, the front end portion 600c of the lateral surface portion 600b on the other end side is disposed on the upper surface portion 102u side of the protrusions 501e and 501f, and is locked by the protrusions 501e and 501f.

  According to such a structure, the cables 431 to 433 are accommodated in the gap passage AS, the cable guide sheet 600 is bent, and the lateral surface portion 600b is locked by the protrusions 501e and 501f so as not to leave the gap passage AS. The cables 431 to 433 can be held. Further, since the cables 431 to 433 wired in the gap passage AS are not restrained by a band, a locking projection, or the like, the cables 431 to 433 can move three-dimensionally in the gap passage AS. Accordingly, even if the cables 431 to 433 are wired slightly deviated from the planned positions, the cables 431 to 433 can be appropriately moved in a direction in which the tension is relaxed by the elasticity of the cable itself. Therefore, the wiring work of the cables 431 to 433 can be facilitated. Moreover, it is suppressed that a strong tension acts on the cables 431 to 433 after wiring continuously.

  Further, for example, when it is necessary to temporarily change the wiring state of the cables 431 to 433 during inspection of the inside of the computer 100, the inspector pinches and pulls up the lateral surface portion 600b of the cable guide sheet 600, and so on. The cable guide sheet 600 returns to the initial state of the I-shaped cross section of FIGS. 5 and 6 only by releasing the locking of the front end portion 600c of the surface portion 600b to the protrusions 501e and 501f by the restoring force of the material itself. At this time, the cables 431 to 433 in the gap passage AS covered with the cable guide sheet 600 are exposed. Therefore, it is possible to quickly start changing the wiring state of the cables 431 to 433. On the other hand, when the inspection or the like is finished, after the cables 431 to 433 are returned into the gap passage AS, the cable guide sheet 600 is bent into an L-shaped cross section as described above, and the front end portion 600c of the lateral surface portion 600b is projected. By locking with 501e and 501f, the cables 431 to 433 can be held so as not to protrude from the gap passage AS.
