The CPU 411 controls the operation of the entire computer 100. The CPU 411 performs arithmetic processing based on the OS stored in the storage unit 220, various application programs, data stored in the storage unit 220, information input from various input devices 230, and the like, and various types described later. To realize the function of. The control unit 210 is composed of, for example, a CPU, an MPU, an FPGA, or the like.

The fan device 500 discharges the heat generated by the CPU 411 during the operation of the CPU 411 to the outside of the second housing 102.

FIG. 2 is a plan view showing the portion indicated by the arrow Z1 in FIG. 1 in a state where the rear side housing is removed and viewed from the back side.

A circuit board 410 is attached to the inner surface of the upper surface portion 102u (predetermined surface portion) of the upper housing 102A of the second housing 102. Electronic components such as CPU 411 are mounted on the circuit board 410. Further, a fan device 500 is attached to the inner surface of the upper surface portion 102u of the upper housing 102A by using screws or the like. The side surface portion 102s of the upper housing 102A is provided with an exhaust port 102a for exhausting the exhaust air of the fan device 500 to the outside.

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 of the rear housing of the second housing in which the fan is arranged, in a state where the cable guide sheet is not bent.

As shown in FIGS. 2, 4, and 5, the vertical wall portion 102c is provided on the inner surface of the upper surface portion 102u of the upper housing 102A so as to project 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 arranged and a battery accommodation space SP2 in which the battery 460 is detachably accommodated. ..

Inside the main space SP1, a cable 431 and 432 connecting the power connector 430 and the circuit board 410, and a cable 433 connecting the speaker 440 and the circuit board 410 are accommodated. Each of the cables 431, 432, and 433 has a metal core wire and a covering material for covering the core wire. The covering material is made of, for example, a flexible and elastic resin, and the cables 431, 432, and 433 can be wired in a bent state.

More specifically, the wiring of the cables 431, 432 and 433 will be described. The cables 431, 432 and 433 are wired by using the gap portion where the parts are not arranged in the main space SP1 and correspond to the shape of the gap. Is bent. The cables 431, 432, and 433 in the bent state tend to be deformed in the direction in which the bending is relaxed due to the restoring force due to the elasticity of the resin covering material. Therefore, even if the wiring is made so as to fit in the gap, the cables 431, 432, and 433 may protrude from the gap over time. In order to prevent this, the computer 100 of the present embodiment adopts 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 is arranged so that the gap passage AS to be formed is formed.

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

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 by utilizing a resin 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 appropriately referred to as a vertical surface portion 600a (a portion on one end side). The vertical surface portion 600a is attached to the vertical wall portion 102c of the upper housing 102A by using, for example, an adhesive.

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

As shown in FIGS. 2 and 4, in the cable guide sheet 600, the portion 600b on the other end side (hereinafter, appropriately referred to as “horizontal surface portion 600b”) has the cable 431 to 433 wired in the gap passage AS as the upper surface portion 102u. Is bent into an L-shaped cross section so as to cover from the opposite side. In the bent state, the tip end portion 600c of the lateral surface portion 600b on the other end side is arranged 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 housed in the gap passage AS, the cable guide sheet 600 is bent, and the side surface portions 600b thereof are locked by the protrusions 501e and 501f so as not to be separated from the gap passage AS. Cables 431 to 433 can be held. Further, since the cables 431 to 433 wired in the gap passage AS are not restrained by the band, the locking projection, or the like, they can move three-dimensionally in the gap passage AS. As a result, even if the cables 431 to 433 are wired slightly deviated from the planned positions, they can be appropriately moved in a direction in which the tension is relaxed due to the elasticity of the cable itself or the like. Therefore, the wiring work of the cables 431 to 433 can be facilitated. Further, it is suppressed that a strong tension continuously acts on the cables 431 to 433 after wiring.

Further, for example, when it is necessary to temporarily change the wiring state of the cables 431 to 433 when inspecting the inside of the computer 100, the inspector picks up the side surface portion 600b of the cable guide sheet 600 and pulls it up to the side. The cable guide sheet 600 returns to the initial state having an I-shaped cross section in FIGS. 5 and 6 by the restoring force of the material itself only by releasing the locking of the tip portion 600c of the surface portion 600b to the protrusions 501e and 501f. At this time, the cables 431 to 433 of 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 completed, after returning the cables 431 to 433 into the gap passage AS, the cable guide sheet 600 is bent into an L-shaped cross section as described above, and the tip portion 600c of the side 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.
