DESCRIPTION OF EMBODIMENTS

A notebook computer will be described as an example of an electronic device. FIG. 1 is an explanatory view of a notebook computer 1 according to the present embodiment. The notebook computer 1 includes housings 10 and 20. The housings 10 and 20 are connected with each other by a two-axis hinge H. The housings 10 and 20 are examples of first and second housings, respectively. The two-axis hinge H is an example of a hinge mechanism. The housing 10 includes a top surface 11, and a bottom surface opposed to the top surface 11. The top surface 11 is an example of a first surface. The housing 10 has a substantially rectangular shape and includes sides 13 to 16. The sides 13 and 14 face each other and are parallel with each other. The sides 15 and 16 face each other and are parallel with each other. The sides 13 and 14 are perpendicular to the sides 15 and 16, respectively. Additionally, the side 13 is behind the housing 20 in FIG. 1.

A keyboard K and a touch pad T for operating the notebook computer 1, covers 30 and 40, and the two-axis hinge H are provided in the top surface 11. The keyboard K and the touch pad T are examples of operation portions. A motherboard for controlling the whole operation of the notebook computer 1 is housed within the housing 10. The covers 30 and 40, and the two-axis hinge H are provided along the side 13. The two-axis hinge H is provided at the center of the side 13. The two-axis hinge H is closer to the side 13 than the sides 14 to 16. The cover 30 is provided between the two-axis hinge H and the side 15. The cover 40 is provided between the two-axis hinge H and the side 16. The cover 30 is an example of a removable cover. The cover 40 is an example of another removable cover.

The housing 20 includes a front surface 21 and a rear surface 22 opposed to the front surface 21. A display D for displaying images is provided at the front surface 21. The housing 20 has a substantially rectangular shape and includes sides 23 to 26. The sides 23 and 24 face each other and are parallel with each other. The sides 25 and 26 face each other and are parallel with each other. The sides 23 and 24 are perpendicular to the sides 25 and 26, respectively.

The two-axis hinge H causes the housings 10 and 20 to rotatably connected with each other about two different axes A1 and A2. The axes A1 and A2 are perpendicular to each other. The axis A1 is perpendicular to the top surface 11. The axis A2 is included in a plane including the top surface 11.

When the housing 20 is rotated about the axis A2 from a state where the top surface 11 and the front surface 21 overlap each other, the Keyboard K and the display D are exposed as illustrated in FIG. 1. In general, a user uses the notebook computer 1 in this state. Additionally, the sides 13 and 23 are parallel with each other in the state illustrated in FIG. 1. Thus, the housing 20 faces the covers 30 and 40.

Next, a description will be given of the work of removing the covers 30 and 40. FIGS. 2 and 3 are explanatory views of the work of removing the covers 30 and 40. As illustrated in FIG. 2, the housing 20 is rotated about the axis A1 to recede from the covers 30 and 40. Therefore, a user can access and remove the covers 30 and 40 from the housing 10 as illustrated in FIG. 3. The cover 30 is fixed to the housing 10 by a screw. The cover 30 is provided with claw portions 34 engaging with a portion of the housing 10. Also, the cover 40 has the same structure. FIGS. 3 and 4 illustrate the state where the cover 30 is removed. Additionally, FIG. 4 illustrates only the housing 10.

A communication card C is housed within the housing 10 at the position covered with the cover 30. This communication card C is connected with a connector provided in the housing 10. This connector is connected with a cable CB routed within the housings 10 and 20 as illustrated in FIG. 3. The cable CB is routed at the backside of the display D in the housing 20 through the two-axis hinge H. An antenna AT is provided near the side 24 within the housing 20. The cable CB is electrically connected with the antenna AT. That is, the communication card C housed within the housing 10 is electrically connected with the antenna AT. The communication card C is removable from the housing 10 and exchangeable. The communication card C is an example of a part. The antenna AT is an example of another part. Additionally, such a communication card is not housed at the cover 40 side.

As mentioned above, the covers 30 and 40 are provided in the housing 10 at the top surface 11 in which the keyboard K and the touch pad T accessed by a user are provided. Thus, by rotating the housing 20 away from the covers 30 and 40, a user can access the covers 30 and 40 with ease. Therefore, it can be easy to remove the covers 30 and 40 and to exchange, attach, and detach the communication card C.

For example, in a case where a cover is provided at the bottom surface of the housing 10, a user has to turn the housing 10 down to access the cover. This work is inconvenient. In the present embodiment, a user does not have to turn the housing 10 down, since the covers 30 and 40 are provided at the top surface 11 in which the keyboard K operated by the user is provided.

For example, in a case where such a cover is provided at the bottom surface to overlap the keyboard K, the part also overlaps the keyboard K, so that the thickness of the housing 10 might increase. In the present embodiment, the covers 30 and 40 are provided in the top surface 11 at an area distanced from the keyboard K and the touch pad T, thereby suppressing the thickness of the housing 10.

The cover 30 is provided near the two-axis hinge H, and the communication card C is housed at the position covered with the cover 30. Thus, this communication card C is housed near the two-axis hinge H. This makes it possible to shorten the length of the cable CB which connects the communication card C with the antenna AT housed in the housing 20. Also, the cost is reduced. Further, the performance of the antenna AT can be improved by shortening the cable CB.

The covers 30 and 40 are provided at the top surface 11 in which the keyboard K accessed by a user is provided. However, the covers 30 and 40 are provided at the position which is not generally accessed by a user in the normal use manner illustrated in FIG. 1. Thus, the covers 30 and 40 are provided at the position which does not influence the area of the keyboard K and the touch pad T occupied in the top surface 11. This ensures the area of the keyboard K and the touch pad T.

FIG. 5 is an explanatory view of a notebook computer 1a according to a variation. In the notebook computer 1a, components that are similar to those of the notebook computer 1 will be denoted by the similar reference numerals, and a detailed description of such components will be omitted. FIG. 5 illustrates only a housing 10a. A keyboard Ka of the notebook computer 1a is held by covers 30a and 40a attached to the housing 10a. Specifically, the keyboard Ka has a substantially rectangular shape and has a side K3 substantially parallel with a side 13a of the housing 10a. In the side K3, plural projections K4 protruding to the side 13a are formed at even intervals. The covers 30a and 40a are attached to the housing 10 to hold the projections K4 of the keyboard Ka. Thus, the Keyboard Ka is fixed to the housing 10a. Therefore, when the covers 30a and 40a are removed from the housing 10a, the keyboard Ka can be removed from the housing 10a. The keyboard Ka can be removed with ease to improve the exchanging work and the maintenance characteristics.
