  The second housing includes a frame arranged on the front side of the display device and covering the edge of the display device, and a cover arranged on the back side of the display device. The cover includes a metal cover that covers the back surface of the display device and a resin cover that is fixed to the upper side of the metal cover. The frame on the front side of the display is also made of resin. The antenna is housed in the upper side of the second housing. That is, the antenna is held between the resin frame and the resin cover. Thereby, communication of the antenna is ensured.

  The frame width may be narrowed in consideration of design and the like. When the antenna is housed on the upper side of the second casing, there is a certain limit in reducing the width of the upper side of the frame. Therefore, it is conceivable to store the antenna on the lower side of the second housing. This is because it is easy for the user to visually recognize the upper side of the second housing, but difficult to visually recognize the lower side. For this reason, even if the width | variety of the lower side of a frame is not narrow, the influence on the design property of the 2nd housing | casing recognized by a user can be suppressed.

  When the antenna is arranged on the lower side, it is necessary to fix the resin cover on the lower side of the metallic cover in order to ensure communication of the antenna. At this time, if the metallic cover and the resin cover are fixed with screws or the like, the number of parts increases.

  An object of the present invention is to provide a portable device having a reduced number of parts.

A portable device disclosed in the present specification includes a first housing, an antenna, a display, a resin frame located on the front side of the display, and a cover located on the back side of the display.

The notebook computer 1 has housings 10 and 20. The casings 10 and 20 are connected to each other around the axis A by a hinge 80 described later so as to be relatively rotatable. The casings 10 and 20 are examples of first and second casings, respectively. The hinge 80 is an example of a hinge mechanism. The housing 10 includes an upper surface 11 and a bottom surface 12 that faces the upper surface 11 and will be described later. The housing 10 has a substantially rectangular shape and includes sides 13 to 16. Sides 13 and 14 are opposed and parallel. The sides 15 and 16 are opposed and parallel. Each of the sides 13 and 14 is orthogonal to each of the sides 15 and 16. Each side 13, 14 is longer than each side 15, 16.

  On the upper surface 11, a keyboard K and a touch pad T for operating the notebook computer 1 are provided. The keyboard K and the touch pad T are examples of the operation unit. A housing for controlling the overall operation of the notebook computer 1 is housed in the housing 10. The axis A is along the side 13.

  The housing 20 includes a front surface 21 and a back surface 22 that faces the front surface 21 and will be described later. The housing 20 holds the display D. The display D is an example of a display device. The screen DP of the display D is exposed on the front surface 21. The housing 20 has a substantially rectangular shape and includes sides 23 to 26. The sides 23 and 24 are opposed and parallel. The sides 25 and 26 are opposed and parallel. Each of the sides 23 and 24 is orthogonal to each of the sides 25 and 26. Each side 23, 24 is longer than each side 25, 26. As shown in FIG. 1, when the housing 20 is opened from the housing 10, the side 24 corresponds to the upper side and the side 23 corresponds to the lower side. The axis A is along the side 23. In other words, the axis A is along the sides 13 and 23 that face each other with the housings 10 and 20 open. Two antennas AT are accommodated on the side 23 side of the housing 20. The side 23 is an example of one side of the second housing.

FIG. 2 is an explanatory diagram of the housing 20 when viewed from the front 21. FIG. 3 is an explanatory diagram of the housing 20 when viewed from the back surface 22. The housing 20 includes a frame 30, a metal cover 40, and a resin cover 50. As shown in FIG. 2, the frame 30 is made of a synthetic resin, covers the outer peripheral edge of the display D, and is positioned on the front 21 side. The frame 30 is set with widths W33 to W36 of sides 23 to 26, respectively. The width W 33 is the largest.

  As shown in FIG. 3, the metal cover 40 and the resin cover 50 are located on the back side of the display D. The metal cover 40 and the resin cover 50 are examples of covers. The metal cover 40 is made of metal and covers the back surface of the display D. The frame 30 is fixed to the metal cover 40. The resin cover 50 is made of synthetic resin, and extends along the side 23 and is disposed on the side 23 side. The metal cover 40 and the resin cover 50 jointly define the back surface 22 of the housing 20. Although described later in detail, the resin cover 50 is partially exposed from the lower side of the metal cover 40.

  The reason why the metal cover 40 is made of metal is that a certain level of strength is required to hold the heavy display D, and that external radio noise that may affect the display D is blocked. Etc. As shown in FIGS. 2 and 3, the antenna AT is retracted from the metal cover 40 and positioned between the frame 30 and the resin cover 50. In other words, the antenna AT is located between the portion of the resin cover 50 exposed from the metal cover 40 and the frame 30. Therefore, since the antenna AT is retracted from the metallic metal cover 40 and held between the resin frame 30 and the resin cover 50, transmission / reception accuracy and sensitivity are ensured.

  FIG. 4 is an exploded perspective view of the housing 20. In FIG. 4, the frame 30 is not shown. Two hinges 80 are provided. The display D is held by a metal cover 40. The display D may be held by the metal cover 40 via another member assembled to the display D, or may be directly held by the metal cover 40.

  5 and 6 are enlarged views around the hinge 80 of FIG. The hinge 80 includes swing pieces 81 and 82 and a shaft 88. The swinging pieces 81 and 82 are rotatably connected to both ends of the shaft 88, respectively. The swing pieces 81 and 82 are fixed to the housings 10 and 20 side, respectively. A fixed portion 84 is formed at the tip of the swing piece 82. The fixing portion 84 is substantially flat and has two through holes PH. The two screws S pass through the through holes PH, respectively, and the fixing portion 84 is fixed to the metal cover 40. Thereby, the swing piece 82 is fixed to the metal cover 40. Similarly, two through holes PH are also formed in the fixing portion 83 formed at the distal end portion of the swing piece 81, and the screw passes through the two through holes PH so that the swing piece 81 is on the side of the housing 10. Fixed to. The number of through holes PH may be one, or may be three or more.

  Two protruding bosses 44 projecting from the inner surface are formed on the inner surface of the metal cover 40. Screw holes SH are formed in the two boss portions 44, respectively. The rocking piece 82 is fixed to the metal cover 40 by screwing the screw S penetrating the through hole PH into the screw hole SH.

  The resin cover 50 is formed with a long hole-shaped escape hole 54 for allowing the fixing portion 84 to escape. The fixing portion 84 is fixed to the boss portion 44 in a state where the resin cover 50 is assembled to the metal cover 40 so that the escape hole 54 is fitted to the boss portion 44. Further, the overlapping portion of the resin cover 50 and the metal cover 40 is bonded by a double-sided tape P. In addition, you may adhere | attach the metal cover 40 and the resin cover 50, for example with adhesive agents other than a double-sided tape. The double-faced tape P is also formed with a long hole-like escape hole P4 for allowing the boss portion 44 to escape. An engaging portion 42 is formed on the inner surface of the metal cover 40, and an engaging portion 52 is formed on the end portion of the resin cover 50. The engaging portions 42 and 52 engage with each other when the resin cover 50 is assembled to the metal cover 40.

  7 is a cross-sectional view taken along the line AA in FIG. 8 is a cross-sectional view taken along the line BB in FIG. 7 and 8 show partial cross sections of the housing 20 after assembly. FIG. 7 shows a hinge cover 90 that covers the hinge 80. 7 and 8, the resin cover 50 is held so as to be sandwiched between the inner surface of the metal cover 40 and the fixing portion 84 of the swing piece 82. . Specifically, the fixing portion 84 that protrudes from the boss portion 44 holds the resin cover 50 between the inner surface and the metal cover 40.

  For example, when the resin cover 50 is fixed to the metal cover 40 using screws or other members, the number of parts increases. In this embodiment, the resin cover 50 is fixed to the metal cover 40 using the metal cover 40 and the hinge 80 fixed to the metal cover 40. Thereby, the number of parts is reduced.

  In addition, the resin cover 50 is not held between the front end surface of the boss portion 44 and the fixing portion 84, and the resin cover 50 is provided with an escape hole 54 for escaping the boss portion 44. It is held between the fixing portion 84. For this reason, compared with the case where the resin cover 50 is sandwiched and held between the front end surface of the boss portion 44 and the fixing portion 84, the overall thickness of the housing 20 is suppressed in this embodiment.

  In addition, since the antenna AT is arranged on the side 23 side, the length of the cable connecting the antenna AT on the housing 10 side can be reduced. Thereby, the wiring work of a cable can be made easy and the cost of a cable can be suppressed.

  When the resin cover 50 is assembled to the metal cover 40, the boss portion 44 is assembled so as to be inserted into the escape hole 54. For this reason, the position of the resin cover 50 with respect to the metal cover 40 can be easily defined. Further, when the double-sided tape P is attached to the metal cover 40, the boss portion 44 is attached so as to be inserted into the escape hole P4 of the double-sided tape P. Thereby, the position of the double-sided tape P with respect to the metal cover 40 can also be easily defined. Thus, the assembly workability is also improved.

  As shown in FIGS. 5, 6, 8, and 9, the two boss portions 44 are arranged in the longitudinal direction of the side 23 of the metal cover 40. For this reason, the area extended in the longitudinal direction of the metal cover 40 can be used effectively.

  In addition, since the metal cover 40 and the resin cover 50 are bonded together with the double-sided tape P as well as the screw S, the resin cover 50 can be more firmly fixed to the metal cover 40. In addition, since the resin cover 50 is restrained to the metal cover 40 not only by the double-sided tape but also by the hinge 80, the adhesive strength is increased as compared with the double-sided tape alone. When the casings 10 and 20 are opened and closed, a load is applied in the vicinity of the hinge 80, and the resin cover 50 is suppressed by the hinge 80, so that the load on the resin cover 50 and the double-sided tape P at the time of opening and closing is reduced.

  Next, the visibility of the frame 30 of the housing 20 in a general usage mode of the notebook computer 1 will be described. FIG. 9 is an explanatory diagram of the visibility of the frame 30 of the housing 20. FIG. 10 is a partially enlarged view of FIG. In general, when the user uses the notebook computer 1, it is assumed that the user's viewpoint VP is at a height of 45 cm from the bottom surface of the apparatus and 25 cm from the front side of the apparatus. In this case, it is considered that the user's line of sight is easy to go to the side 24 side of the housing 20 but hard to go to the side 23 side. Furthermore, in the case of the present embodiment, when the housing 20 is viewed from the user's viewpoint VP with the housing 20 opened from the housing 10, the majority of the housing 20 is the visible area VA. However, the portion of the casing 20 that is on the side 23 side and hidden by the casing 10 is an area NVA that is difficult to visually recognize.

  For this reason, an increase in the width W34 of the frame 30 on the side 24 side is easily recognized by the user, but an increase in the width W33 of the frame 30 on the side 23 side is considered difficult for the user to recognize. Therefore, by arranging the antenna AT on the side 23 side that is difficult for the user to visually recognize, the width W34 of the frame 30 on the side 24 side that is easily visible to the user can be reduced. Further, even if the width W33 is increased by arranging the antenna AT on the side 23 side, it is difficult for the user to recognize the width W33. Thereby, the design of the housing 20 is improved.

  The reason why the region NVA exists in the housing 20 in the present embodiment is that the axis A serving as the rotation center of the hinge 80 is located within the thickness of the housing 10, specifically between the upper surface 11 and the bottom surface 12 of the housing 10. Because it is. For this reason, it is difficult to see the side 23 side of the casing 20 by the casing 10 in a state where the casing 20 is opened from the casing 10. The upper surface 11 is an example of a first surface provided with an operation unit. The bottom surface 12 is an example of a second surface that faces the first surface.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.

  The portable device is not limited to a notebook computer and may be any portable device, and may be a cellular phone, a portable television, an electronic dictionary, a PDA, a game machine, a camera, a music player, or a navigation device.

  The operation unit provided on the upper surface 11 of the housing 10 may be, for example, a touch panel, a trackball, or other buttons and switches.

  In the present embodiment, the axis A of the hinge 80 is located between the upper surface 11 and the bottom surface 12 of the housing 10, but is not limited thereto. For example, the axis of the hinge may be above the upper surface 11 of the housing 10. Even in such a case, as shown in FIGS. 9 and 10, in a general usage mode, the user can easily see the side 24 side than the side 23 side.
