Description

  The present invention relates to an electronic device such as a notebook personal computer and an electronic component mounted on such an electronic device.

Electronic devices such as notebook personal computers are required to be arranged without hindering downsizing and thinning of buttons such as a power switch while improving design. According to Patent Document 1, a power switch is provided at one end of a hinge that rotatably connects a housing provided with a keyboard or the like and a housing provided with a display unit. For example, when the power switch is turned on by the light emitting element, the switch emits light. Thereby, for example, a state in which the power is turned on becomes visually easy to understand.
Japanese Patent Laying-Open No. 2005-128805 (paragraph [0135], FIG. 3, FIG. 35, etc.)

  In the technique described in Patent Document 1, since the power switch is exposed at one end of the hinge, there is a problem that the user or the like accidentally contacts the power switch and the power is unexpectedly turned off. Therefore, it is conceivable to arrange a light-shielding portion that surrounds such a power switch and has a protruding portion protruding from the pressing surface of the power switch. The light shielding portion is plated mainly from the viewpoint of design.

  However, when such a light shielding part is provided, a user who operates the electronic device from the front may be blocked by the light shielding part and cannot confirm the light emission of the power switch.

  In view of the circumstances as described above, an object of the present invention is to provide an electronic device and an electronic component that allow a user operating the electronic device from the front to check the light emission state of a button without impairing the design.

  In order to solve the above problems, an electronic apparatus according to the present invention includes an electronic apparatus main body, a button, an outer peripheral light emitting component, a substrate, a holding member, a supporting member, and an enclosing member. The electronic device main body has a button arrangement portion on one side. The button is arranged in the button arrangement portion, is made of a material that transmits light, has a pressing surface on the one side, and has a substantially cylindrical shape having a light incident surface on the surface opposite to the one side. It is. The outer peripheral light emitting component is disposed at a position facing the light incident surface of the button, has an outer peripheral surface exposed to the outside, and has a substantially cylindrical shape made of a material that scatters light. The substrate is interposed between the button and the outer peripheral light emitting component, and a first light emitting element that emits light toward a light incident surface of the button and a switch element that is pressed and switched are provided on the first surface. A second light emitting element that is mounted and emits light toward the outer peripheral light emitting component is mounted on the second surface. The holding member is a material that is interposed between the button and the substrate, has a projection that can hold the button and abut against the switch element at a position facing the switch element, and scatters light. Consists of. The support member elastically supports the holding member. The surrounding member is made of a material that surrounds the button, the substrate, the holding member, and the support member, has a protruding portion that protrudes from the pressing surface, and does not transmit light.

  In the present invention, it is possible to emit light from the pressing surface of the button, and it is also possible to emit light from the outer peripheral surface of the outer peripheral light emitting component. Therefore, the user operating the electronic device from the front can check the light emission state of the button. The outer peripheral surface of the outer peripheral light emitting component is exposed with the surrounding member sandwiched from one side of the electronic device main body, that is, at a predetermined distance. Therefore, the outer peripheral surface of the outer peripheral light-emitting component exposed so as to emit light is very easy to see by the user operating the electronic device from the front, and the design is not impaired. The holding member is made of a material that scatters light. Therefore, light is emitted uniformly from the pressing surface of the button, and the user cannot see the internal structure from the pressing surface. Therefore, the design is very good. The substrate mounts the first light emitting element, the second light emitting element, and the switch element. Therefore, the number of parts can be reduced and the mounting accuracy can be improved.

The first light emitting element may be disposed in a region substantially on a central axis of the button, and the second light emitting element may be disposed in a region above the central axis of the button.
Accordingly, since the first light emitting element is disposed in a region substantially on the central axis of the button, light is emitted uniformly from the pressing surface of the button. In addition, since the second light emitting element is disposed in the region above the center axis of the button, the upper side of the outer peripheral surface of the outer peripheral light emitting component emits light strongly. A user who operates an electronic device from the front rarely sees the upper part of the eye and the lower part of the eye. Accordingly, it is possible to reduce the amount of light, that is, the power consumption, and reliably notify the user operating the electronic device from the front of the light emission state.

The outer peripheral light emitting component may have a conical recess on the surface opposite to the side on which the substrate is disposed.
Thereby, the light reflected toward the outer peripheral surface of the outer peripheral light emitting component by the conical concave portion becomes stronger. Therefore, it is possible to reliably notify the user of the light emission state by reducing the amount of light, that is, the power consumption.

You may make it comprise the light reflection layer arrange | positioned at the surface on the opposite side to the side by which the said board | substrate is arrange | positioned of the said outer periphery light emitting component.
Thereby, light does not leak from the gap between the side opposite to the side where the substrate of the outer peripheral light emitting component is disposed and the electronic device main body side by the light reflecting layer. As a result, the user appears to have an axis inside, and the design is improved.

The outer peripheral light emitting component, the holding member, and the support member may be configured integrally and have a holding portion that holds the substrate.
As a result, it is possible to reduce the number of parts, improve the mounting accuracy, and reduce the number of mounting steps.

You may make it comprise the diffusion sheet arrange | positioned between the said button and the said holding member.
Thereby, light is emitted more uniformly from the pressing surface of the button, and the user cannot see the internal structure from the pressing surface. Therefore, the design is very good.

The substrate is arranged 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 peripheral light emitting component. You may be made to do.
Accordingly, the second distance can be increased, the amount of light reaching the outer peripheral surface of the outer peripheral light emitting component can be increased, and light can be emitted more strongly from the outer peripheral surface of the outer peripheral light emitting component. Therefore, it is possible to reliably notify the user of the light emission state by reducing the amount of light, that is, the power consumption.

The electronic device main body has a first housing having a first surface provided with an operation unit, and a second surface having a second surface provided with a display unit that can face the first surface. A casing, and a first hinge and a second casing are rotatably connected on the back side of the electronic apparatus main body, and have a cylindrical hinge provided with the button arrangement portion at one end. You may do it.
Thereby, the design property is improved by arranging the button that emits light from the pressing surface and the outer peripheral surface of the light emitting portion at one end of the cylindrical hinge.

  The electronic component according to the present invention includes a button, a peripheral light emitting component, a substrate, a holding member, a support member, and an enclosing member. The button is made of a material that transmits light, and has a substantially cylindrical shape having a pressing surface on one side and a light incident surface on the other side. The outer peripheral light emitting component is disposed at a position facing the light incident surface of the button, has an outer peripheral surface exposed to the outside, and has a substantially cylindrical shape made of a material that scatters light. The substrate is interposed between the button and the outer peripheral light emitting component, and a first light emitting element that emits light toward a light incident surface of the button and a switch element that is pressed and switched are provided on the first surface. A second light emitting element that is mounted and emits light toward the outer peripheral light emitting component is mounted on the second surface. The holding member is a material that is interposed between the button and the substrate, has a projection that can hold the button and abut against the switch element at a position facing the switch element, and scatters light. Consists of. The support member elastically supports the holding member. The surrounding member is made of a material that surrounds the button, the substrate, the holding member, and the support member, has a protruding portion that protrudes from the pressing surface, and does not transmit light.

  In the present invention, it is possible to emit light from the pressing surface of the button, and it is also possible to emit light from the outer peripheral surface of the outer peripheral light emitting component. Therefore, the user operating the electronic component from the front can check the light emission state of the button. The outer peripheral surface of the outer peripheral light-emitting component is exposed with the surrounding member interposed therebetween, that is, with a predetermined distance. Therefore, the outer peripheral surface of the outer peripheral light-emitting component exposed so as to emit light is very easy to see by the user who operates the electronic component from the front, and the design is not impaired. The holding member is made of a material that scatters light. Therefore, light is emitted uniformly from the pressing surface of the button, and the user cannot see the internal structure from the pressing surface. Therefore, the design is very good. The substrate mounts the first light emitting element, the second light emitting element, and the switch element. Therefore, the number of parts can be reduced and the mounting accuracy can be improved.

The first light emitting element may be arranged in a region substantially on the central axis of the button, and the second light emitting element may be arranged in a region above the central axis of the button.
Accordingly, since the first light emitting element is disposed in a region substantially on the central axis of the button, light is emitted uniformly from the pressing surface of the button. In addition, since the second light emitting element is disposed in the region above the center axis of the button, the upper side of the outer peripheral surface of the outer peripheral light emitting component emits light strongly. A user who operates an electronic device on which an electronic component is mounted from the front rarely gets into the eyes on the upper side and gets into the eyes on the lower side. Accordingly, it is possible to reduce the amount of light, that is, the power consumption, and reliably notify the user operating the electronic device from the front of the light emission state.

The outer peripheral light emitting component may have a conical recess on the surface opposite to the side on which the substrate is disposed.
Thereby, the light reflected toward the outer peripheral surface of the outer peripheral light emitting component by the conical concave portion becomes stronger. Therefore, it is possible to reliably notify the user of the light emission state by reducing the amount of light, that is, the power consumption.

You may make it comprise the light reflection layer arrange | positioned at the surface on the opposite side to the side by which the said board | substrate is arrange | positioned of the said outer periphery light emitting component.
Thereby, light does not leak from the gap between the side opposite to the side where the substrate of the outer peripheral light emitting component is disposed and the electronic device main body side by the light reflecting layer. As a result, the user appears to have an axis inside, and the design is improved.

The outer peripheral light emitting component, the holding member, and the support member may be configured integrally and have a holding portion that holds the substrate.
As a result, it is possible to reduce the number of parts, improve the mounting accuracy, and reduce the number of mounting steps.

You may make it comprise the diffusion sheet arrange | positioned between the said button and the said holding member.

Note that the number of light-emitting elements 82 and the emission color are not particularly limited. The light emitting element 82 is disposed in the vicinity of the region corresponding to the central axis K of the button 13. The central axis K is, for example, parallel to the optical axes of the two light emitting elements 82 and is located in the middle of the two optical axes. The light emitting element 82 emits light toward substantially the center of the button 13 (diffusion plate 49). The distance between the light emitting element 82 and the diffusion plate (diffusion sheet) 14 is, for example, a distance L1.

  A light emitting element 83 is provided on a surface 85 opposite to the surface 84 of the mounting substrate 80. As shown in FIG. 5, a plurality of light emitting elements 83 are mounted on the mounting substrate 80 at a predetermined interval. One light emitting element 83 emits green light, and the other light emitting element 83 emits red (orange) light. For example, LEDs (Light Emitting Diodes) are used as the light emitting elements 82 and 83. Note that the number of light-emitting elements 83 and the emission color are not particularly limited. The light emitting element 83 is disposed in a region above the center axis K of the button 13 (a position shifted upward from the center axis K in FIG. 4 in the Z direction). The distance between the light emitting element 83 and the outer surface 70 of the outer peripheral light emitting portion 63 is a distance L2 that is longer than the distance L1. The wiring (not shown) derived from the substrate 17 passes through the lower side of the structure (not shown) inside the main body 3 of the electronic device 1 and is attached to the main body 3 of the electronic device 1.

FIG. 11 is a block diagram illustrating a system configuration of the electronic apparatus 1.
A system 90 of the electronic device 1 includes a substrate 17, a power supply circuit 91, and a system controller 92.

A light emitting element 83 is provided.

  The power supply circuit 91 generates a DC power supply used in each circuit in the electronic device 1 from a commercial AC power supply and a DC DC power supply from a battery.

  The system controller 92 controls the system of the electronic device 1. For example, when a system activation command is input from the switch controller 94, the system is activated. The system controller 92 manages the system status and notifies the switch controller 94 of the system status (system on / off / standby).

  The switch controller 94 outputs, for example, a binary signal to the power supply switching circuit 95 based on the status from the system controller 92. For example, the switch controller 94 outputs “1” to the power supply switching circuit 95 when the status is system on, and outputs “0” to the power supply switching circuit 95 when the status is standby.

  The power supply switching circuit 95 outputs a binary signal to the driver 96 and the driver 97 based on the binary signal from the switch controller 94.

  The driver 96 supplies / cuts off the direct current power generated by the power supply circuit 91 to the light emitting element 82 based on the signal from the power supply switching circuit 95. The driver 97 supplies / cuts off the direct-current power generated by the power supply circuit 91 to the light emitting element 83 based on a signal from the power supply switching circuit 95.

FIG. 12 is an optical path diagram of light emitted from 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 from the light emitting element 82 is uniformly guided by the button holding portion 61 of the support member 16 and is uniformly diffused by the diffusion plate (diffusion sheet) 14. The light diffused by the diffusion plate (diffusion sheet) 14 enters the transparent button 13 from the bottom surface (light incident surface) 43, passes through the button 13, and is emitted from the pressing surface 42. Thereby, the pressing surface 42 of the button 13 emits light in a circular shape. At this time, since the light emitting element 82 is disposed in a region substantially on the central axis K of the button 13, the pressing surface 42 of the button 13 emits light substantially uniformly. As a result, the user can know the state of the electronic device 1 (system on or standby).

  The light emitted from the light emitting element 83 is diffused by the milky white support member 16, enters the outer peripheral light emitting portion 63, and is on the outer peripheral surface 69 side by the light reflecting layer 72 of the outer surface 70 of the conical recess 71 of the outer peripheral light emitting portion 63. Reflects in a ring shape toward As a result, the light from the light emitting element 83 spreads in a ring shape in the direction indicated by the arrow R in FIG. 12 that is 90 degrees with respect to the central axis K of the button 13 and is emitted from the outer peripheral surface 69 into a ring shape. The light incident on the outer peripheral light emitting portion 63 is not transmitted to the side of the light reflecting layer 72 opposite to the outer peripheral light emitting portion 63 side. At this time, the light emitting element 83 is disposed in a region above the center axis K of the button 13 (a position shifted from the center axis K in FIG. 4 upward in the Z direction). The upper side of the surface 69 emits light with higher brightness than the lower side. Thereby, when the user opens and uses the electronic apparatus 1 as shown in FIG. 1, the upper part of the outer peripheral surface 69 of the outer peripheral light emitting unit 63 emits light more brightly.

  As described above, according to the present embodiment, the power switch unit 10 includes the button 13 having the pressing surface 42, the substrate 17 on which the light emitting elements 82 and 83 are mounted, and the one side of the main body 3 of the electronic device 1. And an outer peripheral light emitting portion 63 exposed with the surrounding member 15 interposed therebetween. Therefore, in addition to being able to emit light in a planar shape from the pressing surface 42 of the button 13, it is possible to emit light in a ring shape from the outer peripheral surface 69 of the outer peripheral light emitting unit 63. Therefore, the user who operates the electronic device 1 from the front can check the light emission state of the button 13 and the outer peripheral surface 69 of the outer peripheral light emitting unit 63. At this time, the outer peripheral surface 69 of the outer peripheral light emitting unit 63 is very easy to see by the user operating the electronic device 1 from the front, and the design is not impaired. The holding portion 61 is made of a milky white material that scatters light, and a diffusion plate (diffusion sheet) 14 is disposed on the bottom surface 43 of the button 13. Therefore, light is uniformly emitted from the pressing surface 42 of the button 13 and the user cannot see the internal structure from the pressing surface 42. Therefore, the design is very good. Further, the plating ring 12 is plated, and the inclined surface 23 of the plating ring 12 and the inclined surface 33 of the fixing ring 11 are formed so as to be smoothly connected, so that the design is excellent. The substrate 17 mounts the light emitting element 82, the light emitting element 83, and the switch element 81, and the button holding portion 61, the elastic portion 62, the outer peripheral light emitting portion 63, and the like are integrally configured. Therefore, it is possible to reduce the number of parts, improve the mounting accuracy, reduce the manufacturing cost, and reduce the size.

On the other hand, conventionally, in order to emit light in two opposite directions, in general, two substrates, two light guiding / diffusing components, and a total of five components including an elastic structure to be pressed by the user are required. Become.
In this case, from the viewpoint of structure, it is necessary to arrange 5 parts in the space inside the housing, to ensure sufficient strength of each part, and to further secure the parts to the equipment. Considering this, the volume of the structure itself increases.

  Next, from the viewpoint of manufacturing, since it is a structure consisting of five parts in the past, it is difficult to assemble this structure with high precision considering the dimensional tolerance of each part and the mounting intersection of the parts. . In addition, it is difficult to uniformly produce the light guide component at the same time that the structure is manufactured without difference during mass production. Further, due to the above-described tolerance, problems such as non-operation of the button due to interference between the button and the housing may occur.

  Furthermore, from the viewpoint of cost, the cost increases due to an increase in the number of parts and the number of molds for manufacturing each part. In addition, there is a problem that the cost increases due to an increase in the amount of assembly work on the production line.

  The outer peripheral light emitting part 63 of the support member 16 has a conical recess 71 on the outer surface 70, and a light reflection layer 72 is disposed on the outer surface 70. Thereby, the light incident on the outer peripheral light emitting portion 63 from the light emitting element 83 is reflected in the direction of 90 degrees with respect to the central axis (optical axis) K, and the outer peripheral surface 69 of the outer peripheral light emitting portion 63 emits light in a ring shape. Can do.

  A light reflecting layer 72 is disposed on the outer surface 70 of the outer peripheral light emitting unit 63. Thereby, a gap is formed between the outer surface 70 side of the outer peripheral light emitting part 63 and the connecting part 4a side by the light reflecting layer 72, and light does not leak from this gap. As a result, the user appears to have an axis inside, and the design is improved.

  As shown in FIG. 4, the substrate 17 has a distance L1 between the light emitting element 82 and the diffusion plate (diffusion sheet) 14 larger than a distance L2 between the light emitting element 83 and the outer peripheral light emitting portion 63 (the outer surface 70 thereof). Arranged to be shorter. Accordingly, the distance L2 can be increased, the amount of light reaching the outer peripheral surface 69 of the outer peripheral light emitting unit 63 can be increased, and light can be emitted more strongly from the outer peripheral surface 69 of the outer peripheral light emitting unit 63.

  For example, the electronic device 1 causes the light emitting elements 82 and 83 to light green when the power is on, or causes the light emitting element 83 to blink red (orange) light when in the power saving standby state. , It is possible to make the user confirm the state.

By arranging the power switch unit 10 in the connecting part 4b of the hinge 4 that was a dead space, the degree of freedom of each part arrangement of the main body part 3 and the display part 2 is increased, and by devising the part arrangement Thinning of the main body 3 and the display unit 2 is promoted. The power switch unit 10 is provided at a position away from the keyboard unit 8, and surrounds the button 13, and the outer periphery of the button 13 protrudes. Therefore, it is possible to prevent the power from being accidentally turned off during use.
As shown in FIG. 1, the main body side housing 7 includes an inclined surface 7a that is inclined so as to enter the lower side of the connecting portion 4b. For this reason, since the light emitted from the outer peripheral light emitting unit 63 is reflected by the inclined surface 7a, the user can easily recognize the light emission state of the outer peripheral light emitting unit 63 from the front. Moreover, since the inclined surface 7a has a smooth streamline shape, it is excellent in terms of design.
