)中所揭示之技術中，一電源開關被提供至鉸 接部之一端部，該鉸接部可旋轉地連接一提供有鍵盤與類 似者等之殼體及一互相提供顯示部份之殼體。當電源被打 開時，該電源開關藉由譬如一發光元件放射光線，這使其 易於視覺地辨認該電源被打開之狀態。 e 【發明內容】 在專利文件1中所揭示之技術中，該電源開關係在該 鉸接部之一端部暴露。這造成一使用者不小心地接觸電源 開關及該電源無意中被關掉之問題。由於此，可提供一具 有凸出部份之光屏蔽部份，該凸出部份環繞該電源開關及 如與該電源開關之壓按表面作比較係凸出的。由一設計立 場，該光屏蔽部份係主要地遭受一板件處理等。 然而，當提供該光屏蔽部份時，於一些案例中’操作 -5- 201009547 該電子設備同時面朝它之使用者幾乎不能辨認由該電源開 關所放射之光，因爲該光屏蔽部份屏蔽光線。 由於該前述之情況，其想要的是提供一電子設備及一 電子組件，其允許操作該電子設備同時面朝它之使用者辨 認一按鈕之光線放射狀態，而不會損壞其設計。 根據本發明之一具體實施例，提供有一電子設備，包 括一電子設備主體、一按鈕、一外部圓周發光組件、一基 板、一固持構件、一支撐構件、及一環繞構件。該電子設 備主體包括在其一橫側面上之按鈕放置部份。該按鈕具有 一大致圓柱形之形狀，且被設置在該按鈕放置部份上，及 由一造成光線通過該處之材料所製成。該按鈕包括在該一 橫側面上之壓按表面及在與該一橫側面相反的表面側上之 光入射表面。該外部圓周發光組件具有一大致圓柱形之形 狀’且被設置在一與該按鈕之光入射表面相反的位置上， 及由一散射光線之材料所製成。該外部圓周發光組件包括 一暴露至外側之外部圓周表面。該基板被設置於該按鈕及 該外部圓周發光組件之間，且包括在其上安裝第一發光元 件及一開關元件之第一表面、及在其上安裝第二發光元件 之第二表面。該第一發光元件放射光線朝向該按鈕之光入 射表面。該開關元件係藉由壓按所切換。該第二發光元件 &射光線朝向該外部圓周發光組件。該固持構件固持該按 鈕：’且被設置於該按鈕及該基板之間，並由一散射光線之 材料所製成。該固持構件在一與該開關元件相反之位置包 括一能夠與該開關元件接觸之突出部份。該支撐構件彈性 -6 - 201009547 地支撐該固持構件。該環繞構件環繞該按鈕、該基板、該 固持構件、及該支撐構件，該環繞構件包括一突出部份’ 如與該壓按表面作比較，該突出部份爲突出’且係由一防 止光線通過該處之材料所製成。 於該具體實施例中，光可由該按鈕之壓按表面放射。 此外，光可由該外部圓周發光組件之外部圓周表面放射。 據此，操作該電子設備同時面朝它之使用者能確認該按鈕 之發光狀態。該外部圓周發光組件之外部圓周表面係由該 電子設備主體的一橫側面暴露，同時該環繞構件介入在其 間，亦即，具有一預定之距離。因此，該外部圓周發光組 件之外部圓周表面暴露，以便發光係很輕易地被操作該電 子設備同時面朝它之使用者所確認，且防止該設計損壞。 此外，該固持構件係由散射光線之材料所製成。據此’光 線係由該按鈕之壓按表面均勻地放射，且該使用者經過該 壓按表面看不見該內部結構。因此，該設計變得顯著想要 的。該第一發光元件、該第二發光元件、及該開關元件被 安裝在該基板上。因此，該等零組件的數目中之減少及附 接準確性之改良能被實現。 該第一發光元件可被設置在一大致在該按鈕的中心軸 上之區域上，且該第二發光元件可被設置在一該按鈕的中 心軸上方之區域上。 以此結構，因爲該第一發光元件係大致設置在該按鈕 的中心軸上之區域上，光係由該按鈕之壓按表面均勻地放 射。此外，因爲該第二發光元件係設置在該按鈕的中心軸 -7- 201009547 上方之區域上，該上方區域在該外部圓周發光組件之外部 圓周表面強烈地放射光線。操作該電子設備同時面朝它之 使用者輕易地看見該上方區域，且該使用者幾乎看不見一 下方區域。據此，該發光狀態能以較小光量、亦即以更少 之耗電量藉由操作該電子設備同時面朝它之使用者可靠地 確認。 該外部圓周發光組件可在一相反側面上包括一具有錐 形表面之凹入部份，該相反側面與設置該基板之側面相反 〇 以此結構，藉由具有該錐形形狀的凹入部份反射向該 外部圓周發光組件之外部圓周表面的光被加強。因此，該 發光狀態能以較小光量、亦即以更少之耗電量藉由操作該 電子設備同時面朝它之使用者可靠地確認。 該電子設備可另包括一光線反射層，其設置在該外部 圓周發光組件之表面上，該外部圓周發光組件之該表面係 與設置該基板之側面相反。 以此結構，光被防止由該相反側面及該電子設備主體 側面間之間隙藉由該光線反射層漏出’該相反側面係與該 外部圓周發光組件的基板上之側面相反。其結果是’對於 該使用者其顯露一軸線係設在其內側，這改善該設計。 該外部圓周發光組件、該固持構件、及該支撐構件可 爲具有整體的結構，且該支撐構件可包括一固持該基板之 固持部份。 以此結構，該等零組件的數目中之減少、附接準確性 -8- 201009547 之改善、及附接工作之製程的數目中之減少能被實現。 該電子設備可另包括一擴散薄片，其設置於該按鈕及 該固持構件之間。 以此結構，光係由該按鈕之壓按表面均句地放射，且 該使用者經過該壓按表面看不見該內部結構。據此，該設 計變得顯著想要的。 可設置該基板，以致該第一發光元件及該固持構件間 之第一距離係比該第二發光元件及該外部圓周發光組件間 之第二距離較短。 以此結構，該第二結構被設定爲長的，以增加抵達該 外部圓周發光組件之外部圓周表面的光量，因此光線可由 該外部圓周發光組件之外部圓周表面更強烈地放射。如此 ，該發光狀態能以較小光量、亦即以更少之耗電量藉由操 作該電子設備同時面朝它之使用者可靠地確認。 該電子設備主體可包括第一殼體、第二殼體、及一具 有圓柱形之形狀的鉸接部，該第一殻體具有在其上提供一 操作部份之第一表面，該第二殼體具有能夠面向該第一表 面與在其上提供一顯示部份之第二表面，該鉸接部在該電 子設備主體之背面上可旋轉地互相連接該第一殻體及該第 二殻體，該鉸接部係在其一端部上設有該按鈕放置部份。 以此結構，由該壓按表面及該發光部份之外部圓周表 面放射光線之按鈕被設置在該圓柱形鉸接部之一端部上’ 藉此進一步改善該設計。 根據另一具體實施例，提供有一電子組件。該電子組 -9- 201009547

。據此，操作該電子設備同時面朝它之使用者能確認該按 鈕之發光狀態。該外部圓周發光組件之外部圓周表面被暴 -10- 201009547 露，而該環繞構件介入在其間、亦即以一預定之距離。因 此，該外部圓周發光組件之外部圓周表面暴露，以便放射 光係很輕易被操作該電子設備同時面朝它之使用者所確認 ’且防止該設計損壞。此外，該固持構件係由散射光線之 材料所製成。據此，光係由該按鈕之壓按表面均勻地放射 ，且該使用者經過該壓按表面看不見該內部結構。因此， 該設計變得顯著想要的。該第一發光元件、該第二發光元 件、及該開關元件被安裝在該基板上。因此，能實現零組 件的數目中之減少及附接準確性之改良。 該第一發光元件可大致設置在該按鈕的中心軸上之區 域上，且該第二發光元件可設置在該按鈕的中心軸上方之 區域上。 以此結構，因爲該第一發光元件係大致設置在該按鈕

Description of the Invention [Technical Field] The present invention relates to an electronic device, such as a laptop personal computer, and an electronic component mounted to the electronic device. [Prior Art] It is required that an electronic device such as a laptop PC is provided with a button such as a power switch without impeding reduction in size and thickness, and at the same time improving the design of the electronic device. In the technique disclosed in Japanese Patent Laid-Open Application No. 2005-128805 (paragraph 0135, FIG. 3, 35, etc.) (hereinafter, referred to as Patent Document 1), a power switch is provided to one end of the hinge portion, The hinge portion rotatably connects a housing provided with a keyboard and the like, and a housing that provides a display portion to each other. When the power is turned on, the power switch emits light by, for example, a light-emitting element, which makes it easy to visually recognize the state in which the power is turned on. e SUMMARY OF THE INVENTION In the technique disclosed in Patent Document 1, the power-on relationship is exposed at one end of the hinge. This causes a user to accidentally touch the power switch and the power source is inadvertently turned off. Accordingly, a light-shielding portion having a convex portion that surrounds the power switch and protrudes in comparison with the pressing surface of the power switch can be provided. From a design standpoint, the light shielding portion is primarily subjected to a panel processing or the like. However, when the light shielding portion is provided, in some cases, 'Operation-5-201009547, the electronic device facing the user at the same time can hardly recognize the light emitted by the power switch because the light shielding portion is shielded. Light. Because of the foregoing, it is desirable to provide an electronic device and an electronic component that allows the electronic device to be operated while the user facing it recognizes the light emission state of a button without damaging its design. According to an embodiment of the present invention, an electronic device is provided, comprising an electronic device body, a button, an outer circumferential light emitting assembly, a substrate, a holding member, a supporting member, and a surrounding member. The electronic device body includes a button placement portion on a lateral side thereof. The button has a generally cylindrical shape and is disposed on the button placement portion and is made of a material that causes light to pass therethrough. The button includes a pressing surface on the one lateral side and a light incident surface on the surface side opposite to the one lateral side. The outer circumferential light-emitting assembly has a substantially cylindrical shape and is disposed at a position opposite to the light incident surface of the button and is made of a material that scatters light. The outer circumferential lighting assembly includes an outer circumferential surface that is exposed to the outer side. The substrate is disposed between the button and the outer circumferential light-emitting component, and includes a first surface on which the first light-emitting element and a switching element are mounted, and a second surface on which the second light-emitting element is mounted. The first illuminating element emits light toward the light incident surface of the button. The switching element is switched by pressing. The second illuminating element & ray is directed toward the outer circumferential illuminating assembly. The holding member holds the button: 'and is disposed between the button and the substrate and is made of a material that scatters light. The holding member includes a protruding portion that is in contact with the switching element at a position opposite to the switching element. The support member elastically supports the holding member -6 - 201009547. The surrounding member surrounds the button, the substrate, the holding member, and the supporting member, and the surrounding member includes a protruding portion as compared with the pressing surface, the protruding portion is protruding and is protected by light Made from the material of the place. In this particular embodiment, light can be emitted by the pressing surface of the button. Further, light may be radiated from an outer circumferential surface of the outer circumferential light-emitting assembly. According to this, the user who operates the electronic device while facing it can confirm the light-emitting state of the button. The outer circumferential surface of the outer circumferential lighting assembly is exposed by a lateral side of the body of the electronic device while the surrounding member is interposed therebetween, i.e., has a predetermined distance. Therefore, the outer circumferential surface of the outer circumferential light-emitting assembly is exposed so that the light-emitting system can be easily operated by the user while facing the electronic device and the design is prevented from being damaged. Further, the holding member is made of a material that scatters light. Accordingly, the optical line is uniformly radiated by the pressing surface of the button, and the user cannot see the internal structure through the pressing surface. Therefore, the design has become significantly more desirable. The first light emitting element, the second light emitting element, and the switching element are mounted on the substrate. Therefore, the reduction in the number of such components and the improvement in the accuracy of attachment can be achieved. The first illuminating element can be disposed over an area generally on a central axis of the button, and the second illuminating element can be disposed over an area above the central axis of the button. With this configuration, since the first light-emitting element is disposed substantially on the area on the central axis of the button, the light is uniformly radiated by the pressing surface of the button. Further, since the second light-emitting element is disposed on a region above the central axis -7 - 201009547 of the button, the upper region strongly radiates light on the outer circumferential surface of the outer circumferential light-emitting assembly. The electronic device is operated while the user facing it is easily visible to the upper area, and the user can hardly see a lower area. Accordingly, the illumination state can be reliably confirmed by the user operating the electronic device while facing the user with a small amount of light, i.e., with less power consumption. The outer circumferential light-emitting assembly may include a concave portion having a tapered surface on an opposite side opposite to a side on which the substrate is disposed, by the recessed portion having the tapered shape Light reflected toward the outer circumferential surface of the outer circumferential light-emitting assembly is reinforced. Therefore, the illuminating state can be reliably confirmed by the user who operates the electronic device while facing the user with a small amount of light, that is, with less power consumption. The electronic device can further include a light reflecting layer disposed on a surface of the outer circumferential light emitting component, the surface of the outer circumferential light emitting component being opposite the side on which the substrate is disposed. With this configuration, light is prevented from leaking through the light reflecting layer by the gap between the opposite side and the side surface of the main body of the electronic device. The opposite side surface is opposite to the side surface on the substrate of the outer circumferential light emitting unit. The result is that the user is exposed to an inner axis of the user, which improves the design. The outer circumferential light-emitting assembly, the holding member, and the support member may have an integral structure, and the support member may include a holding portion that holds the substrate. With this configuration, a reduction in the number of such components, an improvement in attachment accuracy -8 - 201009547, and a reduction in the number of processes for attaching work can be achieved. The electronic device can further include a diffusion sheet disposed between the button and the holding member. With this configuration, the light system is uniformly radiated by the pressing surface of the button, and the user cannot see the internal structure through the pressing surface. Accordingly, the design became significantly desired. The substrate may be disposed such that a first distance between the first light emitting element and the holding member is shorter than a second distance between the second light emitting element and the outer circumferential light emitting component. With this configuration, the second structure is set to be long to increase the amount of light reaching the outer circumferential surface of the outer circumferential light-emitting assembly, so that the light can be more strongly radiated from the outer circumferential surface of the outer circumferential light-emitting assembly. Thus, the illumination state can be reliably confirmed by the user operating the electronic device while facing the user with a small amount of light, i.e., with less power consumption. The electronic device body may include a first housing, a second housing, and a hinge having a cylindrical shape, the first housing having a first surface on which an operating portion is provided, the second housing The body has a second surface facing the first surface and a display portion thereon, the hinge portion rotatably interconnecting the first housing and the second housing on a back surface of the electronic device body, The hinge portion is provided with the button placement portion at one end portion thereof. With this configuration, a button for radiating light from the pressing surface and the outer circumferential surface of the light-emitting portion is provided on one end portion of the cylindrical hinge portion, thereby further improving the design. According to another specific embodiment, an electronic component is provided. The electronic group -9-201009547 includes a button, an outer circumferential lighting assembly, a substrate, a holding member, a supporting member, and a surrounding member. The button has a generally cylindrical shape and is made of a material that causes light to pass therethrough. The button includes a pressing surface on one side and a light incident surface on the other side. The outer circumferential light-emitting assembly has a substantially cylindrical shape and is disposed at a position opposite to a light incident surface of the button, and is made of a material that scatters light, and the outer circumferential light-emitting assembly includes an exposed outer side The outer circumferential surface. The substrate is disposed between the button and the outer circumferential light emitting component, and includes a first surface on which the first light emitting element and a switching element are mounted, and a second surface on which the second light emitting element is mounted. The first light-emitting element emits light toward a light incident surface of the button, the switching element is switched by being pressed, and the second light-emitting element emits light toward the outer circumferential light-emitting assembly. The holding member holds the button and is disposed between the button and the substrate and is made of a material that scatters light. The holding member includes a protruding portion capable of coming into contact with the switching element at a position opposite to the switching element. The support member elastically supports the holding member. The surround member surrounds the button, the substrate, the retaining member, and the support member. The wrap member includes a projection that protrudes when compared to the pressing surface and is made of a material that prevents light from passing therethrough. In this particular embodiment, light can be emitted by the pressing surface of the button. Further, light can be radiated from the outer circumferential surface of the outer circumferential light-emitting assembly. According to this, the user who operates the electronic device while facing it can confirm the light-emitting state of the button. The outer circumferential surface of the outer circumferential light-emitting assembly is exposed by a violent -10-201009547, and the surrounding member is interposed therebetween, that is, at a predetermined distance. Therefore, the outer circumferential surface of the outer circumferential light-emitting assembly is exposed so that the radiation system can be easily operated by the electronic device while facing the user's confirmation thereof and the design is prevented from being damaged. Further, the holding member is made of a material that scatters light. Accordingly, the light system is uniformly radiated by the pressing surface of the button, and the user cannot see the internal structure through the pressing surface. Therefore, the design becomes significantly desired. The first light emitting element, the second light emitting element, and the switching element are mounted on the substrate. Therefore, it is possible to achieve a reduction in the number of components and an improvement in attachment accuracy. The first illuminating element can be disposed substantially over a region on a central axis of the button, and the second illuminating member can be disposed over a region above the central axis of the button. With this configuration, since the first light-emitting element is disposed substantially on the area on the central axis of the button, the light is uniformly radiated by the pressing surface of the button. Further, since the second light emitting element is disposed on a region above the central axis of the button, the upper portion strongly radiates light in the outer circumferential surface of the outer circumferential light emitting unit. The electronic device is operated while the user facing the user easily sees the upper area, and the user barely sees a lower area, and the electronic component is mounted on the electronic device. Accordingly, the illumination state can be reliably confirmed by the user operating the electronic device while facing the user with a small amount of light, i.e., with less power consumption. The outer circumferential light-emitting assembly may include a concave portion having a tapered surface on an opposite side opposite to a side on which the substrate is disposed -11 - 201009547 by this structure, by having a concave shape Light that is partially reflected toward the outer circumferential surface of the outer circumferential light-emitting assembly is reinforced. Therefore, the illuminating state can be reliably confirmed by the user who operates the electronic device while facing the user with a small amount of light, that is, with less power consumption. The electronic device can further include a light reflecting layer disposed on a surface of the outer circumferential light emitting component, the surface of the outer circumferential light emitting component being opposite the side on which the substrate is disposed. With this configuration, light is prevented from leaking from the gap between the opposite side and the side surface of the main body of the electronic device by the light reflecting layer, which is opposite to the side surface of the substrate of the outer circumferential light emitting unit. As a result, the user is exposed to an inner side of the axis, which improves the design. The outer circumferential light-emitting assembly, the holding member, and the support member may have an integral structure, and the support member may include a holding portion that holds the substrate. With this configuration, a reduction in the number of such components, an improvement in attachment accuracy, and a reduction in the number of processes for attaching work can be achieved. The electronic device can further include a diffusion sheet disposed between the button and the holding member. With this configuration, the light system is uniformly radiated by the pressing surface of the button, and the user cannot see the internal structure through the pressing surface. Accordingly, the design became significantly desired. The substrate may be disposed such that a first distance between the first light emitting element and the holding member is shorter than a second distance between the second light emitting element and the outer circumferential light emitting component. -12- 201009547 With this configuration, the second structure is set to be long 'to increase the amount of light reaching the outer circumferential surface of the outer circumferential light-emitting assembly' so that light can be more strongly radiated from the outer circumferential surface of the outer circumferential light-emitting assembly. Thus, the illumination state can be reliably confirmed by the user operating the electronic device while facing the user with a small amount of light, i.e., with less power consumption. As described above, according to embodiments, the illuminated state of the button can be operated by the user operating the electronic device while facing it without damaging the design.

Further, the internal structure of the button 13, such as the state of the surface of the substrate 17, can be hidden by the diffusion plate (diffusion sheet) 14. 9A to 9G are a perspective view, a bottom view, a rear view, a left side view, a plan view, a right side view, and a front view, respectively, of the surrounding member 15. The surrounding member 15 includes a surrounding member body 50 having a cylindrical shape and a positioning portion 51. As shown in Fig. 4, the surrounding member body 50 surrounds the fixing ring 11, the plating ring 12, the button 13, the supporting member 16, and the like. The surrounding member 15 is made of a material that prevents light from passing therethrough. On the inner circumferential surface side of the surrounding member main body 50, a positioning projection 52 fitted to the groove 38 of the electric ring 12 is formed. As shown in Figs. 4 and 9B, a plurality of lug portions 54 are formed on the inner circumferential surface of the surrounding member main body 50 on the side of an opening 53. The lug portions 54 are used to secure the support member 16 to the surrounding member 15. As shown in Fig. 4, the lug portions 54 are attached to the hook portions 64 (described later) of the support member 16. As shown in Fig. 4, the surrounding member body 50 includes a protruding portion 55' projecting in the X direction as compared with the pressing surface 42 of the button 13. The protruding portion 55, the fixing ring 11 and the like constitute a protruding portion which is protruded as compared with the button 13 (the pressing surface 42). -18- 201009547 The positioning portion 51' is provided so as to protrude from a side surface of the surrounding member main body 5''. The positioning portion 51 is screwed to, for example, a positioning portion 56 of the main body side housing 7, which is shown in Fig. 1. 10A through 10G are a perspective view, a bottom view, a rear view, a left side view, a plan view, a right side view, and a front view, respectively, of the support member 16. As shown in FIG. 10G, the tonic member 16 includes a button holding portion 61 for supporting the button 13, an elastic portion 62, the outer circumferential light emitting portion 63, the buckle portion 64, and a substrate holding. Part 65 is similar to the like. For the support member 16, a milky white resin material or the like is used which has, for example, translucency and scattered light. The button holding portion 61, the elastic portion 62, the substrate holding portion 65, the outer circumferential light-emitting portion 63, and the hook portions 64 are integrally formed with the like. As shown in Figs. 10A and 10E, a hole 67 is formed in the surface 66 of the button holding portion 61. These holes 67 are formed at positions corresponding to the pins 44 of the button 13. As shown in Fig. 4, the pin 44 of the button 13 is inserted into the holes 67, and thus the button 13 is fixed to the button holding portion 61 (support member 16). On a surface of one of the button holding portions 61 opposite to the side of the button 13, a protruding portion 68 is provided as shown in Figs. 4 and 10G. The protruding portion 68 is disposed at a position opposite to the switching element 81 (described later) as shown in FIG. The button holding portion 61 also has a function, such as a light guiding plate for guiding the light emitted by the light-emitting element 82 (described later) toward the diffusion plate (diffusion sheet) 49 (button 13), as shown in FIG. Show. The button holding portion 61 is 譬 -19- 201009547, which is made of a resin material that scatters light and emits white light. As shown in Figures 4 and 10G, the elastic portion 62 has a curved shape. The elastic portion 6 2 elastically supports the button 13 such that when the user presses the pressing surface 42 of the button 13, the button 13 is recessed in the X direction, and when the user does not When the pressing surface 42 is pressed, the button 13 returns to the original position not shown in FIG. As shown in Fig. 10A, the outer circumferential light-emitting portion 63 has a shape of a circular plate which is larger than the button holding portion 61. The outer circumferential light-emitting portion 63 serves as the light guiding plate and also serves as a cover for the opening 53 of the surrounding member 15, as shown in FIG. As shown in Fig. 4, the outer circumferential surface 69 of the outer circumferential light-emitting portion 63 is not surrounded by the surrounding member 15, and is exposed to the outer side of the surrounding member 15 in an annular form. When the user uses the electronic device 1, as shown in Fig. 1, the outer circumferential surface 69 of the outer circumferential light-emitting portion 63 is exposed to the outside so as to be confirmed by the user. As shown in Fig. 4, the outer circumferential light-emitting portion 63 has an outer diameter substantially the same as the outer diameter of the surrounding member 15. The outer circumferential light-emitting portion 63 is made of, for example, a resin material that scatters light and emits white light. The outer circumferential light-emitting portion 63 has a concave portion 71 having a tapered outer surface 70 which is opposite to a side on which the substrate 17 is disposed. For example, when the outer circumferential light-emitting portion 63 has a radius r of 11 to 11. At 5 mm, the depth d of the concave portion 71 (the depth in the X direction in Fig. 4) is set to 0. 3 to 0. 5 mm. For example, when the radius r is 11. At 5 mm, the depth d is set to 0. 5 mm. It should be noted that those are not limited to this, and if appropriate, can be changed -20- 201009547. On the outer surface 70 of the outer circumferential light-emitting portion 63, a light reflecting layer 72 is provided as shown in Fig. 10B. The light reflecting layer 72 reflects the light so that the light radiated by a light emitting element 83 (described later) leaves the outer circumferential surface 69. The light reflecting layer 72 is formed on the outer surface 70 of the outer circumferential light emitting portion 63 by a pad printing or the like. The outer diameter of the light reflecting layer 72 is smaller than the outer surface 70 of the outer circumferential light emitting portion 63, as shown in Fig. 10B. In the outer surface 70 of the outer circumferential light-emitting portion 63, an annular region along the outer circumference of the outer surface 70 is not covered by the light-reflecting layer 72, and is exposed in an annular form. With this configuration, the light-emitting state of the light from the light-emitting element 83 on the outer circumferential surface 69 is adjusted. As shown in FIG. 4, the lug portion 54 is attached to the hook portions 64, and the hook portions 64 are secured to the surrounding members 15. The hook portion 64 shown in Figs. iA and 10G is hooked to the lug portion 54 shown in Fig. 9B, and thus the support member 16 is fixed to the surrounding member 15. As shown in FIG. 4, the substrate holding portion 65 holds the substrate 17 from both sides of the substrate 17 and the bottom side. The substrate holding portion 65 holds the substrate 17 from a surface 84 side thereof and a surface 85 side. The substrate holding portion 65 is integrally formed with the elastic portion 62, the outer circumferential light-emitting portion 63, and the like. As shown in FIG. 4, in a state, the substrate 17 is held by the substrate holding portion 65, and the switching element (tact switch) 81 is opposite to the protruding portion 68, and the light is emitted. Element 82 generally corresponds to a central region of button retaining portion 61 (button 13). The substrate 17 is provided with a mounting substrate 80, and the switching elements 8 1 , -21 - 201009547 are mounted on the mounting substrate 80 such as the light-emitting elements 82 and 83, and the like. As shown in Fig. 4, the switching element 81 is disposed on the surface 84 of the mounting substrate 80 on the side of the button 丨3 so as to oppose the protruding portion 68. The switching element 81 is turned on/off by contact with the protruding portion 68. As shown in Fig. 4, the light-emitting element 82 is provided on the surface 84 of the mounting substrate 80. The plurality of light-emitting elements 82 are mounted on the mounting substrate 80 at predetermined intervals. For example, one light-emitting element 82 emits green light, and the other light-emitting element 82 emits red (orange) light. It should be noted that the number of the light-emitting elements 82 and the color of the emitted light are not particularly limited. The light-emitting element 82 is disposed in the vicinity of a region corresponding to the central axis K of the button 13. The central axis K is parallel to, for example, the optical axis of the two light-emitting elements 82 and corresponds to an intermediate position between the two optical axes. The light-emitting element 82 emits substantially light toward the center of the button 13 (diffusion plate). The distance between the light-emitting element 8 2 and the diffusion plate (diffusion sheet) 14 is set to a distance L1 〇 on the surface 85 of the mounting substrate 80 opposite to the surface 84, and the light-emitting element 83 is provided. As shown in Fig. 5, a plurality of light-emitting elements 83 are mounted on the mounting substrate 80 at predetermined intervals. One light-emitting element 83 emits green light, and the other light-emitting element 83 emits red (orange) light. For each of the light-emitting elements 82 and 83, for example, an LED (Light Emitting Diode) is used. It should be noted that the number of the light-emitting elements 83 and the color of the emitted light are not particularly limited. The light-emitting elements 83 are disposed on a region above the central axis K of the button -22-201009547 13 (the region displaced upward in the Z direction by the central axis K in Fig. 4). The distance between the light-emitting element 83 and the outer surface 70 of the outer circumferential light-emitting portion 63 is set to a distance L2 longer than the distance L1. A wiring (not shown) led from the substrate 17 is connected to the main portion 3 of the electronic device 1 via a structural portion (not shown) in the main portion 3 of the electronic device 1. Figure 11 is a block diagram showing the structure of the system of the electronic device 1. The system 90 of the electronic device 1 includes the substrate 17, a power supply circuit 91, and a system controller 92. The substrate 17 is provided with the above-described mounting substrate 80. The switching element 81, the light-emitting elements 82 and 83, a switch controller 94, a power switch circuit 95, a driver 96, and a driver 97 are mounted on the mounting substrate. 80. The power supply circuit 91 is generated by a commercial AC power source and a DC power source from a battery, and DC power for the circuit in the electronic device 1. The system controller 92 controls the system of the electronic device 1. For example, although a system start command is input by the switch controller 94, the system controller 92 performs a process 'for starting the system. Again, the system controller 92 manages the state of the system' and notifies the switch controller 94 of the status of the system (on/off/standby of the system). The switch controller 94 outputs a binary signal to the power switch circuit 95 based on, for example, a state from the system controller 92. When the system state system -23-201009547 is turned "on", the switch controller 94 outputs "1" to the power switch circuit 95, and when the state is, for example, standby, outputs "〇" to the power switch circuit 9. 5. The power switch circuit 95 outputs a binary signal to the driver 96 and the driver 97 based on a carry signal from the switch controller 94. Based on the signal from the power switch circuit 95, the driver 96 supplies/cuts the DC power generated in the power supply circuit 91 with respect to the light-emitting element 82. Based on the signal from the power switch circuit 95, the driver 97 supplies/cuts the DC power generated in the power supply circuit 91 with respect to the light-emitting element 83. Figure 12 is a diagram showing the optical path of the light emitted by each of the light-emitting elements 82 and 83. For example, when the user presses the button 13 of the power switch unit 10, the system controller 92 causes the light-emitting elements 82 and 83 to emit light. The light emitted by the light-emitting element 82 is uniformly guided by the button holding portion 61 of the support member 16, and uniformly diffused by the diffusion plate (diffusion sheet) 14. Light diffused by the diffusing plate (diffusion sheet) 14 enters the transparent button 13 from the bottom surface (light incident surface) 43, passes through the button 13, and causes the button 42 to exit the button. Therefore, the circular surface radiation of light is applied by pressing the surface 42 of the button 13. At this time, since the light-emitting element 82 is disposed substantially on the area on the central axis K of the button 13, the pressing surface 42 of the button 13 uniformly emits light. As a result, the user can confirm the status of the electronic device 1 (the system is turned on or on standby). -24- 201009547 The light emitted by the light-emitting element 83 is diffused by the milk-white supporting member 16 into the outer circumferential light-emitting portion 63, and is conically recessed by the outer circumferential light-emitting portion 63. The light reflecting surface 72 of the outer surface 70 of the portion 71 is reflected in an annular form toward the outer circumferential surface 69. As a result, the light emitted by the light-emitting element 83 is diffused in a circular direction in a direction indicated by an arrow R of FIG. 12 and perpendicular to the central axis K of the button 13, and The outer circumferential surface 69 is radiated in an annular form. The light that has entered the outer circumferential light-emitting portion 63 does not pass therethrough through a side surface of the light-reflecting layer 72, which side surface is opposite to the outer circumferential light-emitting portion 63. At this time, the light-emitting element 83 is disposed on a region above the central axis K of the button 13 (a region displaced upward in the Z direction by the central axis K in Fig. 4). Therefore, the light radiated from the upper side of the annular outer circumferential surface 69 of the outer circumferential light-emitting portion 63 provides a higher luminance than the light radiated from the lower side thereof. Thus, when the user uses the electronic device 1 in the open state, as shown in Fig. 1, the outer portion of the outer circumferential light-emitting portion 63

As described above, according to this embodiment, the power switch unit 10 includes a button 13 having the pressing surface 42, a substrate 17 on which the light-emitting elements 82 and 83 are mounted, and exposed to the outside while the electron One side surface of the main body portion 3 of the apparatus 1 sandwiches the outer circumferential light-emitting portion 63 of the circumferential portion 15. Therefore, the surface of the light can be radiated by the pressing surface 42 of the button 13. Further, the light may be radiated in an annular form by the outer circumferential surface 69 of the outer circumferential light-emitting portion 63. According to this, the user who faces the electronic device 1 at the same time can confirm the light-emitting state of the button 13 and the outer circumferential surface 69 of the outer circumferential light-emitting portion 63. At this time, the user who faces the electronic device 1 while facing it can easily inspect the outer circumferential surface 69 of the outer circumferential light-emitting portion 63 and prevent the design from being damaged. Further, the holding portion 61 is made of a material that scatters light of white light, and the diffusion plate (diffusion sheet) 14 is provided on the bottom surface 43 of the button 13. Therefore, the light system is uniformly radiated by the pressing of the button 13 on the surface 42, and the user does not see the internal structure through the pressing surface 42. As a result, a design that is significantly desired can be obtained. Further, the plating ring 12 is subjected to the plating, and the inclined surface 23 of the plating ring 12 and the inclined surface 33 of the fixing ring U are formed to be smoothly connected, which provides an excellent design. The light-emitting elements 82 and 83 and the switching element 81 are mounted on the substrate 17, and the button holding portion 61, the elastic portion 62, the outer circumferential light-emitting portion 63, and the like are integrally formed. As a result, a reduction in the number of components, an improvement in attachment accuracy, and a reduction in manufacturing cost and size can be achieved. In contrast, in the related art, in order to radiate light in two opposite directions, including two substrates, two light guide bows/diffusion components, and five components of an elastic structure pressed by the user Generally it can be needed. In this case, from the standpoint of a structure, when the five components are disposed in the casing, the sufficient strength of the components is ensured, and the components for fixing the components to the device are used. Space, the capacity of the structure itself increases. Secondly, from the standpoint of manufacturing, it is difficult to accurately assemble the structure consisting of the components of the five-26-201009547 components in terms of the dimensional tolerances and the tolerances of the components. The structure. In addition, it is difficult to manufacture such structures, and there is no difference in commercial production, and it is difficult to cause the light guiding components to uniformly emit light. Furthermore, a problem can occur here in which a button does not operate due to interference between the button and the housing, the interference being caused by the tolerance described above. Moreover, from the standpoint of cost, the increase in the number of such components and the number of molds used to make the component increases the cost. Moreover, an increase in the number of assembly work in a production line increases the cost. The outer surface 70 of the outer circumferential light-emitting portion 63 of the support member 16 includes the tapered recessed portion 71. The light reflecting layer 72 is provided on the outer surface 70. With this configuration, the light having entered the outer circumferential light-emitting portion 63 by the light-emitting element 83 is reflected in a direction perpendicular to the central axis (optical axis) K, which can cause the outer circumferential light-emitting portion 63. The outer circumferential surface 69 emits light in an annular form. The light reflecting layer 72 is provided on the outer surface 70 of the outer circumferential light emitting portion 63. With this configuration, a gap is formed between the outer surface 70 of the outer circumferential light-emitting portion 63 and the connecting portion 4a, and the light reflecting layer 72 prevents light from leaking through the gap. As a result, it appears to the user that it appears to provide an axis on the inside thereof to improve the trick. As shown in FIG. 4, the substrate 17 is disposed such that the distance L 1 between the light-emitting element 82 and the diffusion plate (diffusion sheet) 14 is greater than the outer surface 70 of the light-emitting element 83 and the outer circumferential light-emitting portion 63. The distance between L2 -27- 201009547 is shorter. With this configuration, by increasing the distance L2 and increasing the amount of light reaching the outer circumferential surface 69 of the outer circumferential light-emitting portion 63, light can be more strongly radiated from the outer circumferential surface 69 of the outer circumferential light-emitting portion 63. For example, when the power source is turned on, the electronic device 1 causes the light-emitting element 82 to indicate green light, or causes the light-emitting element 83 to blink red in a power-saving and standby state, as the user can confirm the result of those states. Orange) light. In the connecting portion 4b of the hinge portion 4 which was once a wasted space, the power switch unit 10 is disposed, thereby generating the freedom of configuration for the main body portion 3 ® and the components of the display portion 2 degree. It is advantageous to reduce the thickness of the main body portion 3 and the display portion 2 by conceiving a method of setting those components. Further, the power switch unit 10 is disposed at a position away from the keyboard unit 8 and surrounds the button 13 such that the outer circumference of the button 13 protrudes. According to this, it is possible to prevent a state in which the power source is accidentally turned off during use. As shown in Fig. 1, the main body side casing 7 includes a sloped slope 7a so as to enter the lower side of the joint portion 4b. With this configuration, the light radiated by the outer circumferential light-emitting portion 63 is reflected by the slope 7a, and thus the user can easily visually confirm the light-emitting state of the outer circumferential light-emitting portion 63 from the front. Further, the slope 7a has a smooth streamlined shape which provides the excellent design. The present invention is not limited to the above specific embodiments. The present invention can be variously modified within the scope of the technical idea of the present invention. The scope of execution of this modification is within the technical scope of the present invention. -28- 201009547 In the above specific embodiment, the example is described, wherein the present invention is applied to the laptop PC, but the present invention is not limited thereto. The invention can be applied to, for example, another electronic device provided with a power switch. In the above specific embodiment, the example is described, wherein the present invention is applied to the push-button power switch unit 10, but the present invention is not limited thereto. The invention can be applied, for example, to a rotary button. Examples of the rotary button may include an operation button of a remote controller, a wiper of a car, or a knob of an electronic appliance. In the above specific embodiment, the substrate holding portion 65 of the support member 16 holds the substrate 17, and the substrate is sandwiched by the surface 84 and the surface 85, but the present invention is not limited thereto. Alternatively, the support member 16 may be provided with a holding portion which is held by the side surfaces of the substrate 17 and the light-emitting element 83 is disposed at the central axis K of the button 13. On the upper area (the area shifted upward by the central axis K in Fig. 4 in the Z direction). The position of the light-emitting element 83 is not limited to this. Alternatively, the light-emitting elements 83 can be mounted on the mounting substrate 80, such as on a side of the button axis 13 that is closer to the user. With this configuration, on the outer circumferential surface 69 of the outer peripheral light-emitting portion 63, the light is radiated more strongly from a portion closer to the upper portion of the user. Operating the electronic device while the user facing it allows for a brighter emission of light closer to the upper portion of the user.
