Description of the Invention: [Technical Field of the Invention] The present invention relates to an electronic device such as a notebook computer. [Prior Art] An electronic device such as a notebook computer is required to be equipped with a push button such as a power switch without impeding the miniaturization of the design. According to Patent Document 1', a power switch is provided at one end of a hinge that rotatably connects a casing provided with a keyboard or the like to a casing on which the display portion is provided. In the power-on relationship, when the power source is turned on, for example, by the light-emitting element, the on-state relationship emits light. Thereby, for example, the state in which the power source is turned on is visible, and it is very easy to know. (Patent Document 1) Japanese Patent Laid-Open Publication No. H05- 1 2 8 8 0 5 (paragraph [0135], FIG. 2, FIG. 25, etc.) [Summary of the Invention] (Problems to be Solved by the Invention) In the technique described in Document 1, since the power-on relationship is exposed at one end of the pivot, there is a problem that the user or the like accidentally touches the power switch and accidentally causes the power to disappear. Therefore, it is considered to configure a light blocking portion having a projection which surrounds the periphery of the power switch as shown above and which protrudes more than the lower surface of the power switch. The light-shielding portion is mainly subjected to plating or the like from a design viewpoint. However, if the light-shielding unit is installed as described above, the user who is operated by the front side will be blocked by the light-shielding unit and the light of the power switch cannot be confirmed. In view of the above circumstances, an object of the present invention is to provide an electronic apparatus which can confirm the lighting state by a user who operates the electronic device on the front side without impairing design. (Means for Solving the Problems) In order to solve the above problems, an electronic device according to the present invention includes an electronic device body, a button, a holding member, a supporting member, a switching element, a light emitting element, and a surrounding member. The electronic device system described above has a button arrangement portion on one side. The button is disposed in the button arrangement portion and is formed of a material that transmits light to form a disk shape having a first radius. The first member of the holding member is adjacent to the button in a concentric manner, and is formed of a material that scatters light, and has a disk shape that is larger than a second radius of the first radius, and is formed by the first surface. The first position on which the center of the second surface on the opposite side is displaced has a protruding portion. The support member sandwiches the center of the holding member, and the holding member is elastically supported by the electronic device body side at a second position opposite to the first position. The switching element is disposed to face the protruding portion on the main body side of the electronic device, and is in contact with the protruding portion to be switched. The light-emitting element is disposed on the side of the electronic machine body, and is capable of emitting light toward a substantially center of the second surface of the holding member, and emits light in accordance with switching by the switching element. The surrounding member is fixed to the electronic device main body side, covers the outer peripheral surface of the button, and the holding member, and the -6-201003367 1 region corresponding to the outer peripheral surface of the button does not transmit light, and is retained with respect to the above. Light is transmitted through at least a portion of the annular region of the second region corresponding to the outer peripheral surface of the member. In the present invention, when the user presses the button, the protruding portion presses the switching element to cause the light emitting element to emit light. The light from the light-emitting element is incident on the second surface of the holding member, and the material that scatters light on the first surface of the holding member is scattered and transmitted through the button. The light from the light-emitting element is reflected by a material that scatters light on the first surface, and is transmitted through at least one of the annular regions of the second region of the surrounding member. Therefore, the light emitted by the light-emitting element is uniformly radiated uniformly by at least one of the annular regions among the second regions of the surrounding member. Therefore, the user who operates the electronic device on the front side can confirm the light-emitting state without losslessness and design. The surrounding member may be formed of a material that does not adhere to plating in a plating process with respect to a first portion corresponding to at least one of the second regions, and is related to at least the first region. The corresponding second part is composed of a material to which plating is adhered in the plating process, and is provided with plating that adheres to at least the surface of the second portion and does not pass light. Thereby, the plating system can be adhered to the surface of the second portion without being shielded by the surrounding member in the plating process. A diffusion sheet disposed between the button and the holding member may be provided. By this, the button can hide the inner side of the structure. In addition, light can be uniformly emitted from the surface of the button. The electronic device body may have a first frame body having a first surface provided with a portion of the 201003367 portion, a second frame body 'opposable surface facing the first surface' and having a second surface on which the display portion is provided; In the cylindrical pivot, the first frame and the second frame are rotatably coupled to the back side of the electronic device body, and the button arrangement portion is provided at one end. Thereby, the user who operates the electronic device on the front side can confirm, for example, the light emission of the power switch. (Effects of the Invention) As described above, according to the present invention, the user who operates the electronic device on the front side can confirm the light-emitting state by the non-destructive and design property.

The holding member 14 is made of a light-transmissive resin material such as milky white. As shown in Fig. 5, a diffusion sheet 26 is disposed between the button 13 and the holding member 14. Since the diffusion sheet 26 is disposed, light can be uniformly emitted from the surface of the button 13. Furthermore, the inner configuration of the button 13 can be hidden, such as the surface state of the substrate 16. Fig. 10 (A), (B), (C), (D) and (E) support the plane, the left side, the front side, the right side and the bottom side of the member 15. The support member 15 is provided with a ring portion 30, an elastic portion 31, a substrate holding portion 32, a fixing portion 33, and the like.

Fig. 11 is a block diagram showing the constitution of the system of the electronic machine 1. The system 6 of the electronic device 1 includes a substrate 16, a power supply circuit 46, and a system controller 50. The substrate 16 includes a mounting substrate 45, a switch member 35 mounted on the mounting substrate 45, a switch controller 51' power supply switching circuit 52, a driver 53, a light-emitting device 36, and a driver 54. And the light-emitting element 5 5 . The power supply circuit 46 generates a DC power source used in each circuit in the electronic device 1 from a commercial ac power source and a DC DC power source from the battery. System Control Benefits 50 is the control of the system of the electronic machine 1. For example, -13- 201003367 When the system start command from the switch controller 51 is input, the processing of the start system is performed. Further, the system controller 50 manages the status of the system (status), and notifies the switch controller 51 of the status of the system (system on/off/standby). When the switching element 35 is pressed by the protrusion 28, the switching element is switched on and off. The switch controller 51 is based on the on/off state of the switching element 35 and the state from the system controller 50, for example, The signal is output to the power switching circuit 52. When the switch controller 51 is turned on, for example, when the system is turned on and the switching element 35 is turned on, "1" is output to the power supply switching circuit 52. When the state is standby and the switching element 35 is turned on, the system is turned "". It is output to the power supply switching circuit 52. The power switching circuit 52 outputs a binary signal to the driver 53 and the driver 54 based on the two signals from the switch controller 51. The driver 53 supplies the DC power generated by the power supply circuit 46 to the light-emitting element 36 based on the signal from the power supply switching circuit 52. The driver 54 supplies the DC power generated in the power supply circuit 46 to the light-emitting element 55 based on the signal from the power supply switching circuit 52. Next, the optical path of the light emitted from the light-emitting element 36 of the power switch unit 10 will be described. Fig. 12 is a view showing the optical path of the light emitted from the light-emitting element 36 of the power switch unit 1. The light emitted from the light-emitting element 36 is incident on the holding member 14 by the second surface 27, and a part of the light is scattered by the diffusion sheet 26, and is emitted toward the outside of the button 13 through the transparent button 1 3 -14 to 201003367. A part of the light incident on the holding member 14 by the second surface 27 is reflected by the diffusion sheet 26. As a result, the reflected light is uniformly radiated uniformly from the vicinity of the center of the holding member 14 toward the inner peripheral surface of the annular light transmitting portion 17 . The radially reflected light is incident on the inner peripheral surface of the annular light-transmitting portion 17, passes through the annular light-transmitting portion 17, and is uniformly diffused in a ring shape toward the outside of the annular light-transmitting portion 17. As described above, the power switch unit 10 includes the light shielding portion 18 provided in a region corresponding to the outer peripheral surface of the button 13 and the region corresponding to one portion of the outer peripheral surface of the holding member 14. The annular light transmitting portion 17 is. When the user presses the button 13 and the protrusion portion 28 pushes the switching element 35, and the switching element 35 is turned on, the light-emitting element 36 emits light. The light emitted from the light-emitting element 36 enters the second surface 27 of the holding member 14 and passes through the holding member 14, is scattered by the diffusion sheet 26, passes through the button 13, and is reflected by the diffusion sheet 26 on the first surface 24. The reflected light is radially diffused and uniformly transmitted through the annular light transmitting portion 17. As a result, the light emitted from the light-emitting element 36 passes through the button 13 and is transmitted radially by the annular light-transmitting portion 17. Therefore, in the case where the plating 18b is left and the design is ensured, the power switch unit 1 of the electronic device 1 can be directly confirmed in the case of viewing the posture of the display surface 6 without viewing the side of the electronic device 1. Light state. The electronic device 1 lights up the light-emitting element 36 to a red (orange) color when the power source is turned on, or causes the light-emitting element 55 to flash green when the power-saving standby state is used, and can be used. The person confirms these statuses. The annular light transmitting portion 17 of the power switch unit 10 is in a state in which it is often exposed to the outside without being in an open/close state of the electronic device 1. Therefore, even if the display unit 2 is directly turned off in the case where the power of the -15-201003367 is turned on, the light from the annular light transmitting portion 17 can be visually recognized without viewing the button 13 of the electronic device 1. The annular light transmitting portion 17 is made of a light transmissive resin material (Clear PC, transparent polycarbonate, etc.) to which the plating 18b is not adhered in the plating process, and the base material of the light shielding portion 18 is used in the plating process. The light-shielding base material 18 8a of the intermediate plating plating 8b is formed. Therefore, for example, the first surrounding member 11 including the annular light transmitting portion 17 and the light blocking portion 18 can be formed in the same plating process. Therefore, the manufacturing process can be shortened, and the manufacturing cost can be reduced. By arranging the power switch unit 10 at the connection portion of the pivot that belongs to the dead space, the degree of freedom is generated in each part of the main body 3 or the display unit 2, and the arrangement of the parts is used. The thickness of the main body portion 3 or the display portion 2 is promoted. Further, the power switch unit 10 is provided at a position separated from the keyboard unit 8, and is formed to surround the periphery of the button 13, and the outer periphery of the button 13 is projected to protrude. Therefore, it is prevented from cutting the power supply or the like in use. The present invention is not limited to the above embodiment. The present invention can be implemented in various modifications within the scope of its technical idea. This scope of implementation is within the technical scope of the present invention.
