そして、デザイン上の観点からも、端部や周囲の厚さを薄くし、電子機器の薄さを強調したいという要求があった。
しかし、電子機器の端部や周囲の厚さを薄くすると、これらの薄くした電子機器の端部や周囲には、例えば、部品実装の観点からは、実装の妨げになるという問題があった。 In recent years, electronic devices such as notebook personal computers (notebook PCs) are becoming smaller and thinner.
In addition, there is a tendency to favor electronic device designs reminiscent of miniaturization and thinning.
From the viewpoint of design, there has been a demand to emphasize the thinness of electronic devices by reducing the thickness of the edges and surroundings.
However, if the thickness of the end portion or the periphery of the electronic device is reduced, there is a problem that the end portion or the periphery of the thinned electronic device may hinder mounting from the viewpoint of component mounting, for example.

このため、電子機器の端部や周囲の厚さを薄くした場合に、これらのスペースを有効利用することが課題になっていた。   For this reason, when the thickness of the edge part and circumference | surroundings of an electronic device is made thin, it has been a subject to use these spaces effectively.

The electronic device (notebook PC) 100 can download a desired program or content from an external server or the like via the network I / F 29.

この実施の形態においては、上記のような電気的な構成から発生する熱を冷却する冷却ファンが、端部や周囲の厚さが薄くなった電子機器に、後述するように設けられる。   In this embodiment, a cooling fan that cools the heat generated from the electrical configuration as described above is provided in an electronic device having a thin end portion or a surrounding portion, as described later.

図３は、端部や周囲の厚さが薄くなった電子機器の構成を示す図である。
図３（ａ）は、この電子機器１００の断面図である。
符号１０ａは第１筐体部、符号１０ｂは第２筐体部である。
また、筐体１０には、例えば、上記電気的な構成を実行するための多くの電子部品が収容される。そして、筐体１０は、実質的に多くの領域を占める第１筐体部１０ａ、および、例えば、この第１筐体部１０ａの端部や周囲に設けられる第２筐体部を備えている。 FIG. 3 is a diagram illustrating a configuration of an electronic device in which an end portion and a surrounding thickness are thinned.
FIG. 3A is a cross-sectional view of the electronic device 100.
Reference numeral 10a denotes a first housing part, and reference numeral 10b denotes a second housing part.
In addition, the housing 10 accommodates, for example, many electronic components for executing the electrical configuration. And the housing | casing 10 is provided with the 1st housing | casing part 10a which occupies substantially many area | regions, and the 2nd housing | casing part provided in the edge part and circumference | surroundings of this 1st housing | casing part 10a, for example. .

この第１筐体部１０ａは、電子部品が収容できるように、少なくとも所定の厚さを備えている。
また、第２筐体部１０ｂは、例えば、デザイン上の観点から、電子機器の薄さを強調するため、端部や周囲の厚さを薄くしており、上記第１筐体部１０ａの所定の厚さよりも薄い、第２の厚さを備えている。 The first housing portion 10a has at least a predetermined thickness so that electronic parts can be accommodated.
In addition, for example, from the viewpoint of design, the second housing portion 10b has a thin end portion and surrounding thickness in order to emphasize the thinness of the electronic device. The second thickness is smaller than the thickness of the second thickness.

近年、部品実装の観点から、ファン（羽根）３１を、上記第１筐体部１０ａの端部や周囲に設けられる第２筐体部１０ｂに近寄せたいという要求がある。
