It is in contact with the metal bezel 21. Thereby, the conductor 31 is in electrical communication with the metal bezel 21.

  Each of the pair of hinge portions 9a and 9b includes a hinge mechanism 41 as shown in FIG. FIG. 7 illustrates the structure of the right hinge 9a. The hinge mechanism 41 is provided between the housing 11 of the display unit 2 and the housing 5 of the main unit 3. The hinge mechanism 41 is made of metal. The hinge mechanism 41 has a hinge shaft 42 and first and second sheet metal members 43 and 44 connected to the hinge shaft 42. At least one of the first and second sheet metal members 43 and 44 is rotatably connected to the hinge shaft 42.

  As shown in FIG. 7, the first sheet metal member 43 extends into the housing 11 of the display unit 2 along the metal bezel 21 of the side surface portion 12 c of the display device 12. The first sheet metal member 43 is provided from one end to the other end of the display device 12. The first sheet metal member 43 includes, for example, two fixing portions 46 to which the display device 12 is fixed. The fixing portion 46 is provided with a screw insertion hole 48 through which the screw 47 is inserted. The display device 12 is provided with a screw hole 49 facing the screw insertion hole 48. The display device 12 is fixed to the first sheet metal member 43 by passing the screw 47 through the screw insertion hole 48 and screwing into the screw hole 49.

  The fixing portion 46 of the first sheet metal member 43 is in contact with the metal bezel 21 of the display device 12. Thereby, the metal bezel 21 is in electrical communication with the first sheet metal member 43. In the fixing portion 46, the first sheet metal member 43 is pressed against the metal bezel 21 relatively strongly by the screws 47. That is, the metal bezel 21 is secured to the first sheet metal member 43 with high electrical conductivity.

  Although not shown in detail, the left hinge portion 9b has the same structure as described above. That is, a total of four fixing portions 46 are provided on the left and right of the display device 12. Further, as shown in FIG. 7, the first sheet metal member 43 has another fixing portion 50 that is fixed to the housing 11.

  On the other hand, as shown in FIG. 7, the second sheet metal member 44 extends toward the inside of the housing 5 of the main unit 3 and is fixed to the housing 5. The second sheet metal member 44 is in electrical communication with the ground 7 of the main unit 3. Thereby, the whole hinge mechanism 41 is in electrical communication with the ground 7 of the main unit 3. More specifically, the metal bezel 21 of the display device 12 is in electrical communication with the ground 7 of the main unit 3 via the hinge mechanism 41.

  As shown in FIGS. 3 and 6, the housing 11 is provided with an engagement mechanism 52 that fixes the mask member 17 to the cover member 18. As shown in FIG. 3, the engagement mechanisms 52 are provided on both the left and right sides of the conductor 31, for example. The engaging mechanism 52 has a structure in which the conductor 31 is pulled toward the metal bezel 21 by fixing the mask member 17 and the cover member 18, and presses the conductor 31 toward the metal bezel 21.

  As shown in FIG. 6, an example of the engagement mechanism 52 includes a first hook portion 53 provided on the cover member 18 and a second hook provided on the mask member 17 and engaged with the first hook portion 53. And a hook portion 54. By engaging the second hook portion 54 with the first hook portion 53, the conductor 31 is pressed against the metal bezel 21, and high conductivity is ensured between the conductor 31 and the metal bezel 21.

Next, the operation of the portable computer 1 will be described.
As described above, the conductor 31 opens a distance from the imaging window 26 that is smaller than the distance between the imaging window 26 and the circuit board 24 of the camera module 13. Therefore, much of the static electricity that jumps into the housing 11 from the photographing window 26 is drawn into the conductor 31 and does not reach the circuit board 24 of the camera module 13.

  In the portable computer 1, a path through which static electricity flows from the conductor 31 to the ground 7 of the main unit 3 through the metal bezel 21 and the hinge mechanism 41 of the display device 12 is secured. As a result, the static electricity drawn into the conductor 31 is released to the ground 7 of the main unit 3 without continuing to charge the conductor 31.

  According to the portable computer 1 having such a configuration, it is possible to prevent the camera module 13 from being damaged due to static electricity with a simple structure. That is, the distance between the imaging window 26 and the circuit board 24 of the camera module 13 is smaller than the distance between the imaging window 26, and the metal bezel of the display device 12 is attached to the periphery of the imaging window 26. When the conductor 31 in contact with 21 is provided, much of the static electricity that jumps into the housing 11 from the photographing window 26 is attracted to the conductor 31 before reaching the circuit board 24 of the camera module 13. Thereby, it is possible to prevent the camera module 13 from being discharged directly and to suppress the electrostatic breakdown of the camera module 13.

  Note that if the distance L1 between the opening edge 26a of the photographing window 26 and the edge of the opening 32 of the conductor 31 is smaller than the distance L2 between the photographing window 26 and the circuit board 24, the photographing window 26 is connected to the housing. Most of the static electricity that jumps into the body 11 can be drawn to the conductor 31 before reaching the circuit board 24 of the camera module 13. Thereby, the electrostatic breakdown of the camera module 13 can be suppressed.

  If the distance L3 between the center of the photographing window 26 and the edge of the opening 32 of the conductor 31 is smaller than the distance L2 between the photographing window 26 and the circuit board 24, the photographing window 26 and the casing 11 are provided. It is possible to attract more of the static electricity jumping into the conductor 31 before reaching the circuit board 24 of the camera module 13, and to suppress electrostatic breakdown of the camera module 13 at a higher level.

  When the conductor 31 is in contact with the metal bezel 21 provided around the display screen 14, the static electricity drawn into the conductor 31 is immediately released through the metal bezel 21. That is, it can be said that a static electricity countermeasure structure is realized with a simple structure by effectively utilizing the metal bezel 21 of the display device 12.

  In particular, by utilizing the metal bezel 21 on the front side of the display device 12, the length of the path through which static electricity escapes can be made relatively short. Thereby, the static electricity which jumps in from the imaging | photography window 26 can be escaped to the ground 7 of the main body unit 3 stably and reliably.

  The conductor 31 provided in the housing 11 can be made simpler and rougher than a decorative member that touches the user's eyes. Therefore, even if the conductor 31 is provided as a countermeasure against static electricity, if the decorative member provided in the photographing window 26 can be omitted, the productivity of the portable computer 1 can be improved and the cost can be reduced. .

  When the conductor 31 is attached to the front wall portion 11a of the housing 11, the conductor 31 can be easily disposed near the photographing window 26, and the static electricity that has jumped into the photographing window 26 can be more reliably attracted. Further, since the conductor 31 is integral with the mask member 17 when the display unit 2 is assembled or disassembled, workability is improved.

  When the conductor 31 is formed in a sheet shape and attached so as to be along the front wall portion 11a of the housing 11, the conductor 31 is less likely to get in the way in the housing 11, and other parts Almost does not disturb the layout.

  In addition to the first portion 31 a positioned around the photographing window 26, the conductor 31 includes a second portion 31 b sandwiched between the front wall portion 11 a of the housing 11 and the metal bezel 21 of the display device 12. If it has, the contact between the conductor 31 and the metal bezel 21 can be ensured more easily and reliably. This contributes to the realization of a more stable antistatic structure.

  When the metal bezel 21 of the display device 12 is in electrical communication with the ground 7 of the main unit 3 via the hinge mechanism 41, a path for effectively discharging the static electricity to the ground 7 of the main unit 3 using the hinge mechanism 41. Can be said to be realized with a simple structure.

  The hinge mechanism 41 includes a sheet metal member 43 extending into the housing 11 along the metal bezel 21 of the display device 12. The sheet metal member 43 is fixed to the display device 12 and contacts the metal bezel 21. When 46 is provided, the electrical communication between the metal bezel 21 and the hinge mechanism 41 can be more securely ensured. This contributes to the realization of a more stable antistatic structure.

  If the mask member 17 is fixed to the cover member 18 and an engagement mechanism 52 for pressing the conductor 31 toward the metal bezel 21 is provided, the conductor 31 is prevented from being lifted from the metal bezel 21. Contact between the metal 31 and the metal bezel 21 can be more reliably ensured. This contributes to the realization of a more stable antistatic structure.

  If the engagement mechanism 52 is realized by the first and second hook portions 53 and 54, for example, the number of parts can be reduced and a seal for hiding the screw is not required as compared with the case where a screw or the like is used. That is, the engagement mechanism 52 can be realized with a simpler structure.

  Next, a portable computer 1 as an electronic apparatus according to a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected and the description which abbreviate | omits the structure which has the same or similar function as the structure of the said 1st Embodiment.

  The engagement mechanism 52 includes, for example, a screw hole 61 provided in the cover member 18 and a screw 62 that is attached to the mask member 17 and screwed into the screw hole 61. Specifically, the mask member 17 is provided with a screw insertion hole 63 facing the screw hole 61. The screw 62 is inserted into the screw insertion hole 63 from a region that is outside the housing 11 and is screwed into the screw hole 61. For example, a rubber cushion 64 is attached to the housing 11 and the screw 62 is covered and hidden.

  The mask member 17 is fixed to the cover member 18 by the engagement mechanism 52. When the screw 62 is screwed into the screw hole 61, the conductor 31 is pressed against the metal bezel 21, and high conductivity is ensured between the conductor 31 and the metal bezel. The configuration of the portable computer 1 other than that described above is the same as that of the first embodiment.

According to the portable computer 1 having such a configuration, it is possible to prevent the camera module 13 from being damaged by static electricity with a simple structure, as in the first embodiment.
According to the engagement mechanism 52 having the screw 62 and the screw hole 61, the conductor 31 can be pressed more strongly against the metal bezel 21 than the hook structure or the like by tightening the screw 62. Thereby, higher electrical conductivity can be ensured between the conductor 31 and the metal bezel 21.

  The engagement mechanism 52 may include, for example, a screw hole 61 provided in the mask member 17 and a screw 62 that is attached to the cover member 18 and screwed into the screw hole 61. Such an engagement mechanism 52 can also provide the same effect as described above.

  Next, a portable computer 1 as an electronic apparatus according to a third embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected and the description which abbreviate | omits the structure which has the same or similar function as the structure of the said 1st Embodiment.

  The display device 12 includes a metal bezel 21 partially on the back surface portion 12b, for example. Between the metal bezel 21 and the conductive layer 19 of the cover member 18, a conductive member 71 that secures electrical conductivity between the metal bezel 21 and the conductive layer 19 is provided. The conductive member 71 is, for example, a ground spring or a conductive gasket.

  The conductive layer 19 of the cover member 18 is in electrical communication with the hinge mechanism 41 at a fixing portion 50 between the cover member 18 and the first sheet metal member 43, for example. Thereby, the metal bezel 21 of the display device 12 is in electrical communication with the ground 7 of the main unit 3 via the conductive layer 19 of the cover member 18 and the hinge mechanism 41. The configuration of the portable computer 1 other than that described above is the same as that of the first embodiment.

  According to the portable computer 1 having such a configuration, it is possible to prevent the camera module 13 from being damaged by static electricity with a simple structure, as in the first embodiment. In place of the cover member 18 having the conductive layer 19, a metal cover member may be used.
