As shown in Figures 2 and 3, be accommodated on the circuit substrate 200 of housing 100 inside, on the solder side 200a relative with the base plate 111 of the first shell 110, slim surface mount device 210 be welded on circuit pattern (pattern).Opposing face (components and parts installed surface) 200b of circuit substrate 200 is equipped with multiple light emitting diode 200 and the larger circuit components 221 of thickness.Light emitting diode 220 and the larger circuit components 221 of thickness are welded with the circuit pattern of solder side 200a by not shown lead-in wire (lead) terminal running through circuit substrate 200.In present embodiment 1, this straight (straight) mode adopting the light-emitting area of each light emitting diode 220 to parallel with the opposing face 200b of circuit substrate 200 is directly mounted on circuit substrate 200.In addition, as the circuit components 221 that thickness is larger, comprise the circuit components that the opposite side connector (connector) of outside terminal for connecting platform 222, power capacitor (condenser) geometric ratio are relatively large.As shown in Figure 1, outside terminal for connecting platform 222 is arranged to the state exposed from the opening portion of the front periphery wall 122a being formed at second housing 120.In addition, circuit substrate 200 is provided with the additional connector 223 being exposed to the first shell 110 outside.This additional connector 223, for when electronic equipment is connected with the lateral location of elementary cell 2, makes the electronic circuit of circuit substrate 200 be electrically connected with the electronic circuit of elementary cell 2.
On the other hand, as shown in Figure 1, on this electronic equipment, the front periphery wall 122a of second housing 120 is provided with display window hole 126, as shown in Figure 3, the side walls 121 of second housing 120 is provided with base portion 140.
Display window hole 126 is the openings for carrying out visual confirmation to the some light of the light emitting diode 220 be mounted on circuit substrate 200 in housing 100 outside, becomes the circle with same inner diameter respectively.In Fig. 1 of present embodiment 1, circuit substrate 200 is equipped with three light emitting diodes in the mode being equally spaced arranged in row along above-below direction, the front periphery wall 122a of second housing 120 is provided with three the display window holes 126 corresponding with each light emitting diode 200 in the mode equally spaced arranged along above-below direction.As shown in Figure 5 and Figure 6, part front periphery wall 122a being formed with display window hole 126 is provided with thinner wall section 128.Thinner wall section 128 arranges recess to form by comprising in the rectangular area in display window hole 126 the outstanding end face from front periphery wall 122a.The mode that the perisporium 128a forming the recess of this thinner wall section 128 increases gradually with, area inner the closer to housing 100 tilts.As shown in Figure 7, display window hole 126 is formed as outer surface aperture efficiency inner surface opening large trapezoidal (taper).
Light conductor 131 remains on the second housing 120 by base portion 140, and this light conductor 131 is for being directed to display window hole 126 by the some light of the light emitting diode be mounted on circuit substrate 200 220.Light conductor 131 is arranged respectively to each light emitting diode 220.In present embodiment 1, as shown in Figure 4, apply and become prismatic following light conductor 131: at base end part, there is inclined plane part 131a, and there is in leading section luminous leading section 131b.Inclined plane part 131a is the plane tilted with 45° angle degree relative to the long side direction of light conductor 131.As shown in Figure 7, in this light conductor 131, if the some light injecting light emitting diode 220 from the side 131c of base end part, then on inclined plane part 131a, there is orthogonal reflection, thus be directed into the luminous leading section 131b of leading section.The size of light conductor 131 has the sectional area equal or larger with the display window hole 126 of second housing 120 respectively.As shown in Figure 1, the luminous leading section 131b of light conductor 131, relative to display window hole 126, is arranged to the gap with ring-type around, and has the external diameter circular cross-section less than the internal diameter in display window hole 126.
These light conductors 131 are formed as one by connecting elements 132, form guide-lighting aggregate 130.Connecting elements 132 becomes thickness ratio light conductor 131 and wants thin prismatic, three light conductors 131 each other with at equal intervals and parallel state be connected.In order to suppress by the situation of connecting elements 132 to adjacent light conductor 131 light leak, the position arranging connecting elements 132 is set as be partial on the thickness direction of light conductor 131.In present embodiment 1, transparent resin material and Merlon is utilized to carry out one-body molded to light conductor 131 and connecting elements 132.
Outstanding to the first shell 110 from the part close to front periphery wall 122a in the side walls 121 base portion 140 that this guide-lighting aggregate 130 carries out keeping being arranged in second housing 120.The elasticity holding plate 143 that this base portion 140 is provided with three groove portions 141, is arranged on the light-tight partition 142 between groove portion 141 and arranges accordingly with light-tight partition 142.
Groove portion 141 is the recesses of the nose portion being formed at base portion 140, when relatively arranging the luminous leading section 131b of light conductor 131 with display window hole 126, can receive the base end part of light conductor 131 under the state of engaging.Light-tight partition 142 is parts that the part mutual from groove portion 141 is outstanding to the first shell 110, is formed by opaque molding resin material.When the side of light conductor 131 and groove portion 141 abut against, light-tight partition 142 is formed as giving prominence to each other from light conductor 131, and respective front end is in the position near circuit substrate 200.Can clearly see from figure, the nose portion of light-tight partition 142 is provided with inclined plane 142a in both sides, and the closer to the first shell 110, then the width of this inclined plane 142a diminishes gradually.Elasticity holding plate 143 is outstanding to the first shell 110 from the position between light-tight partition 142 and front periphery wall 122a, and respective leading section has claw 143a.When the leading section of light conductor 131 and front periphery wall 122a that are accommodated in groove portion 141 abut against, elasticity holding plate 143 is arranged to the mode of the inner surface light conductor 131 to be pressed to gently by connecting elements 132 thinner wall section 128 and connecting elements 132 abuts against, and by making claw 143a engage with connecting elements 132 to limit light conductor 131 to move to the direction away from groove portion 141.In addition, the label 121a in Fig. 3 is when carrying out shaping to second housing 120, for carrying out the punching of shaping metal pattern to the claw 143a of the elasticity holding plate 143 as overhead kick (undercut).
When guide-lighting aggregate 130 is installed on the base portion 140 of second housing 120, make luminous leading section 131b from after the direction that the thinner wall section 128 relative to front periphery wall 122a tilts navigates to display window hole 126, be pressed between elasticity holding plate 143 and front periphery wall 122a, thus connecting elements 132 is slipped into from claw 132a.Namely, if by connecting elements 132 between the inclined-plane press-in elasticity holding plate 143 and front periphery wall 122a of claw 143a, then elasticity holding plate 143 bends in the mode leaving front periphery wall 122a, thus the claw 143a of front end is retreated, therefore when without the need to guaranteeing that housing 100 inside has the space supplying the movement of guide-lighting aggregate 130, whole guide-lighting aggregate 130 can be installed in base portion 140.Particularly because front periphery wall 122a is provided with thinner wall section 128, therefore easily aforesaid operations can be carried out.And, owing to being arranged on identical second housing 120 by the base portion 140 supported guide-lighting aggregate 130 and the display window hole 126 that is provided with luminous leading section 131b, therefore exactly luminous leading section 131b can be set to display window hole 126.Be arranged on guide-lighting aggregate 130 in the base portion 140 of second housing 120 and be resiliently held with respective light conductor 131 mode that plate 143 lifts gently upward, be clamped between the inner surface of front periphery wall 122a, and fastened by the claw 143a and connecting elements 132 making elasticity holding plate 143, be maintained to make the state stoping the side of light conductor 131 to leave the movement in groove portion 141.
Therefore, housing 100 is being decomposed into the first shell 110 and second housing 120, or the first shell 110 and second housing 120 is being assembled when forming housing 100, easily can carry out operation.And carrying out between these operational periods, guide-lighting aggregate 130 can not come off from second housing 120, guide-lighting aggregate 130 therefore also can not be caused to damage, lose such problem.And owing to being provided with prismatic light conductor 131 on the direction parallel with circuit substrate 200, the size on therefore orthogonal with circuit substrate 200 direction can not increase, and can realize the miniaturization of housing 100.
When the light emitting diode 220 being equipped on circuit substrate 200 is lighted, as shown in Figure 7, by luminous leading section 131b and the annular gap s that forms between luminous leading section 131b and the perisporium in display window hole 126, to the outer blaze of housing 100.That is, the luminous leading section 131b of light conductor 131 becomes the first light-emitting area, and the gap s between luminous leading section 131b and display window hole 126 becomes the second light-emitting area.Therefore, even if such as production batch (lot) is different, the light-emitting area that the first light-emitting area evenly overlaps with the second light-emitting area can also be obtained in multiple display window hole 126.In addition, the light-emitting area of the light emitting diode 220 observed from front is the aperture area in display window hole 126, by display window hole 126 being set be greater than the luminous leading section 131b of light conductor 131, thus can improve light emitting diode 220 light visuality.And, when display window hole 126 being set larger than the luminous leading section 131b of light conductor 131, also tool has the following advantages: namely, when guide-lighting aggregate 130 is installed to base portion 140, luminous leading section 131b is made to become comparatively easy from the oblique operation navigating to display window hole 126b.And for display window hole 126, be greater than the trapezoidal of the inner surface of front periphery wall 122a owing to being formed as outer surface aperture area, therefore, the slip changing light-emitting area during sight line is inhibited, and improves the visuality of light emitting diode 220.
In addition, the connecting elements 132 that guide-lighting aggregate 130 is arranged to connection three light conductors 131 is partial to the thickness direction of light conductor 131.Therefore, the light leak produced to each other from light conductor 131 is inhibited, when therefore such as another light emitting diode 200 being extinguished when making an adjacent light emitting diode 220 light, can confirm that another light emitting diode 200 is in OFF state exactly.And, when guide-lighting aggregate 130 is not arranged at base portion 140 of second housing 120 with normal posture, because the groove portion 141 of base portion 140 is different from the distance between connecting elements 132, therefore cannot, when the side of light conductor 131 and groove portion 141 abut against, elasticity holding plate 143 and connecting elements 132 be abutted against.Therefore, guide-lighting aggregate 130 can not be installed in base portion 140 mistaking under positive and negative state, thus light-output can be lighted to luminous leading section 131b reliably by light emitting diode 220.
And, when the side of light conductor 131 and groove portion 141 abut against, the light-tight partition 142 by opaque resin forming materials is arranged to give prominence to each other from light conductor 131, and respective front end is in the position near circuit substrate 200.And, in the both sides of the nose portion of light-tight partition 142, be provided with inclined plane 142a in the mode diminished gradually the closer to the first shell 110, width.Therefore, light conductor 131 can not only be remained in base portion 140 with stable state, also can not other components and parts be mounted on circuit substrate 200 be counteracted, and the direct light leak that can suppress between adjacent light conductor 131, and the roundabout light leak from a light conductor 131 to another light conductor 131 that produces because of the reflection from circuit substrate 200 can be prevented.
In addition, above-mentioned embodiment 1 is passed the imperial examinations at the provincial level and is illustrated display window hole 126 and is formed as the trapezoidal situation that outer surface aperture area is greater than the inner surface of front periphery wall 122a, but it is equal with outer surface aperture area also display window hole shape can be become inner surface aperture area.In addition, although be provided with circular display window hole 126, the opening shape in display window hole 126 is not limited only to circle, also can be arbitrary polygon.For luminous leading section 131b section shape too, can be arbitrary polygon.Therefore, if such as change the opening shape in display window hole 126 according to the classification kind of displaying contents, then can obtain light emitting diode 220 color distinguish beyond means of identification.But no matter carry out what kind of combination to the shape in display window hole 126 and the section shape of luminous leading section 131b, if consider light-emitting area, then preferred surrounding between luminous leading section 131b and display window hole 126 guarantees gap s.
In addition, about the end surface shape of luminous leading section 131b, plane or spherical can be adopted, but be preferably set for can not be outstanding to the outside of housing 100 from display window hole 126 dimensional tolerance.If luminous leading section 131b is not projected into the outside of housing 100, then not only the outside cleaning of housing 100 becomes comparatively easy, also can prevent in advance to cause damage when cleaning to luminous leading section 131, or due to inappropriate pressing cause the elasticity holding plate 143 of base portion 140, the connecting elements 132 of guide-lighting aggregate 130 damages.
And although elasticity holding plate 143 is configured in light conductor 131 each other, the present invention is not limited to this.Such as, when arranging multiple light emitting diode 220, if make connecting elements 132 outstanding to the left and right sides of connected multiple light conductors 131, and by elasticity holding plate 143, this connecting elements 132 outstanding from left and right is pressed, then can the spaced of light conductor 131 be set narrower, can taking up room of guide-lighting aggregate 130 be cut down.
In addition, although inclined plane 142a to be arranged on the nose portion of light-tight partition 142, light-tight partition 142 to be all set in whole length range flat section shape and also can to serve the same role effect.
Embodiment 2
Fig. 8 is the figure of the major part section of the electronic equipment representing embodiment of the present invention 2.Here illustrative electronic equipment is identical with embodiment 1, comprising: the housing 100 be made up of left and right the first shell 110 in a pair and second housing 120; And be accommodated in the circuit substrate 200 of housing 100 inside, be with the difference of embodiment 1, three light emitting diodes 320 that circuit substrate 200 carries and for light emitting diode 320 lighted the structure of light-output to the light conductor 131 in the display window hole 126 on the front periphery wall 122a being formed in second housing 120.
That is, circuit substrate 200 equally spaced carries three light emitting diodes 320 are configured to respective light-emitting area orthogonal with the opposing face 200b of circuit substrate 200.As shown in Figure 8, this light emitting diode 320 can apply connector is the structure that right angle (right angle) mode obtains.Or, also mode that can be orthogonal with the opposing face 200b with circuit substrate 200 arranges assisting base plate, and on this assisting base plate, carry the light emitting diode 320 of straight manner, thus it is orthogonal with the opposing face 200b of circuit substrate 200 to be configured to light-emitting area, also can combine said structure.
Light conductor 331 is respectively arranged with to each light emitting diode 320.As shown in Figure 9, apply the light conductor 331 of prism-shaped in present embodiment 2, this light conductor 331 has straight parts 331a at base end part and has luminous leading section 331b in leading section.Straight parts 331a is the plane with the long side direction of light conductor 331 angle in 90 °.In this light conductor 331, the optical path of lighting of the light emitting diode 320 injected from the straight parts 331a of base end part directly advances, and is fed to the luminous leading section 331b of leading section.
In addition, three light conductors 331 are formed as one by connecting elements 332, form guide-lighting aggregate 330.Because connecting elements 332 becomes thinner than light conductor 331 prismatic, therefore three light conductors 331 with each other at equal intervals and parallel state be interconnected.In order to suppress by connecting elements 332 to adjacent light conductor 331 light leak, the position arranging connecting elements 332 is set as be partial on the thickness direction of light conductor 331.In present embodiment 2, transparent resin material and Merlon is utilized to carry out one-body molded to light conductor 331 and connecting elements 332.
In addition, following content is identical with embodiment 1: namely, and the size of light conductor 331 has the sectional area equal or larger with the display window hole 126 of second housing 120; Further, the luminous leading section 331b of light conductor 331 has the external diameter circular cross-section less than the internal diameter in display window hole 126, thus is arranged to the gap s in surrounding relative to display window hole 126 with ring-type.In addition, identical label is marked for structure identical with embodiment 1 in embodiment 2, and omit respective detailed description.
In embodiment 2, when guide-lighting aggregate 330 is installed to base portion 140 of second housing 120, if make luminous leading section 331b from after the direction that the inner surface relative to front periphery wall 122a tilts navigates to display window hole 126, be pressed between elasticity holding plate 143 and front periphery wall 122a, slip into from the inclined-plane of claw 143a to make connecting elements 332, then elastic holders 143 bends in the mode leaving front periphery wall 122a, retreat to make the claw 143a of front end, therefore also can when without the need to guaranteeing that housing 100 inside has the space supplying the movement of guide-lighting aggregate 330, whole guide-lighting aggregate 330 can be installed to base portion 140.Particularly because front periphery wall 122a is provided with thinner wall section 128, therefore easily aforesaid operations can be carried out.And, because the base portion 140 that supports guide-lighting aggregate 330 and the display window hole 126 that is provided with luminous leading section 331b are all arranged on identical second housing 120, therefore exactly luminous leading section 331b can be set to display window hole 126.Be arranged on guide-lighting aggregate 330 in the base portion 140 of second housing 120 and be resiliently held with respective light conductor 331 mode that plate 143 lifts gently upward, be clamped between the inner surface of front periphery wall 122a, and fastened by the claw 143a and connecting elements 332 making elasticity holding plate 143, be maintained to make the state stoping the side of light conductor 331 to leave the movement in groove portion 141.
Therefore, housing 100 is being decomposed into the first shell 110 and second housing 120, or the first shell 110 and second housing 120 is being assembled when forming housing 100, easily can carry out operation.And during carrying out these operations, guide-lighting aggregate 330 can not come off from second housing 120, therefore also can not cause the damage of guide-lighting aggregate 330, lose such problem.And owing to arranging prismatic light conductor 331 on the direction parallel with circuit substrate 200, the size on therefore orthogonal with circuit substrate 200 direction also can not increase, and can realize the miniaturization of housing 100.
When the light emitting diode 320 that circuit substrate 200 carries is lighted, as shown in Figure 8, by luminous leading section 331b and the annular gap s that forms between luminous leading section 331b and the perisporium in display window hole 126, to the outer blaze of housing 100.That is, the luminous leading section 331b of light conductor 331 becomes the first light-emitting area, and the gap s between luminous leading section 331b and display window hole 126 becomes the second light-emitting area.Therefore, even if such as production batch is different, the light-emitting area that the first light-emitting area evenly overlaps with the second light-emitting area can also be obtained in multiple display window hole 126.In addition, the light-emitting area of the light emitting diode 320 observed from front is the aperture area in display window hole 126, by display window hole 126 being set be greater than the luminous leading section 331b of light conductor 331, thus can improve light emitting diode 320 light visuality.And, when display window hole 126 being set larger than the luminous leading section 331b of light conductor 331, also tool has the following advantages: namely, when guide-lighting aggregate 330 is installed to base portion 140, the operation making luminous leading section 331b navigate to display window hole 126b from oblique direction becomes comparatively easy.And for display window hole 126, be greater than the trapezoidal of the inner surface of front periphery wall 122a owing to being formed as outer surface aperture area, therefore, the slip changing light-emitting area during sight line is suppressed, and improves the visuality of light emitting diode 320.And, in embodiment 2, the light-emitting area being configured to light emitting diode 320 is orthogonal with the opposing face 200b of circuit substrate 200, and the some light of light emitting diode 320 advances straight in the inside of light conductor 331, therefore improve guide-lighting efficiency compared with embodiment 1, the visuality of some light improves further.
In addition, the connecting elements 332 that guide-lighting aggregate 330 is arranged to connection three light conductors 331 is partial to the thickness direction of light conductor 331.Therefore, the light leak produced to each other from light conductor 331 is inhibited, when therefore such as another light emitting diode 320 being extinguished when making an adjacent light emitting diode 320 light, can confirm that another light emitting diode 320 is in OFF state exactly.And, when guide-lighting aggregate 330 is not arranged at base portion 140 of second housing 120 with normal posture, because the groove portion 141 of base portion 140 is different from the distance between connecting elements 332, therefore cannot, when the side of light conductor 331 and groove portion 141 abut against, elasticity holding plate 143 and connecting elements 332 be abutted against.Therefore, guide-lighting aggregate 330 can not be installed in base portion 140 mistaking under positive and negative state, thus light-output can be lighted to luminous leading section 331b reliably by light emitting diode 320.
And, when the side of light conductor 331 and groove portion 141 abut against, the light-tight partition 142 by opaque resin forming materials is arranged to give prominence to each other from light conductor 331, and respective front end is in the position near circuit substrate 200.And, be provided with inclined plane 142a in the both sides of the nose portion of light-tight partition 142 in the mode diminished gradually the closer to the first shell 110, width.Therefore, light conductor 331 can not only be remained in base portion 140 with stable state, also can not other components and parts be mounted on circuit substrate 200 be counteracted, and the direct light leak that can suppress between adjacent light conductor 331, and the roundabout light leak from a light conductor 331 to another light conductor 331 that causes because of the reflection from circuit substrate 200 can be prevented.
In addition, above-mentioned embodiment 2 is passed the imperial examinations at the provincial level and is illustrated display window hole 126 and is formed as the trapezoidal situation that outer surface aperture area is greater than the inner surface of front periphery wall 122a, but it is equal with outer surface aperture area also display window hole shape can be become inner surface aperture area.In addition, although be provided with circular display window hole 126, the opening shape in display window hole 126 is not limited only to circle, can be arbitrary polygon.For luminous leading section 331b section shape too, can be arbitrary polygon.Therefore, if such as change the opening shape in display window hole 126 according to the classification kind of displaying contents, then can obtain light emitting diode 320 color distinguish beyond means of identification.But no matter carry out what kind of combination to the shape in display window hole 126 and the section shape of luminous leading section 331b, if consider light-emitting area, then preferred surrounding between luminous leading section 331b and display window hole 126 guarantees gap s.
In addition, about the end surface shape of luminous leading section 331b, plane or spherical can be adopted, but be preferably set for can not from display window hole 126 to the outside outstanding dimensional tolerance of housing 100.If luminous leading section 331b is not projected into the outside of housing 100, then not only the outside cleaning of housing 100 becomes comparatively easy, also can prevent in advance to cause damage when cleaning to luminous leading section 331, or due to inappropriate pressing cause the elasticity holding plate 143 of base portion 140, the connecting elements 332 of guide-lighting aggregate 330 damages.
And although elasticity holding plate 143 is configured in light conductor 331 each other, the present invention is not limited to this.Such as, when arranging multiple light emitting diode 320, if make connecting elements 332 outstanding to the left and right sides of connected multiple light conductors 331, and by elasticity holding plate 143, this connecting elements 332 outstanding from left and right is pressed, then can the spaced of light conductor 331 be set narrower, can taking up room of guide-lighting aggregate 330 be cut down.In addition, in embodiment 2, because the some light of light emitting diode 320 is injected from straight parts 331a, therefore light conductor 331 not necessarily will adopt prismatic, also can adopt cylindrical.But, when adopting columniform light conductor 331, preferably the groove portion 141 of base portion 140 is also configured to the recess of semicircular arc.
In addition, although inclined plane 142a to be arranged on the nose portion of light-tight partition 142, light-tight partition 142 to be all set in whole length range flat section shape and also can to serve the same role effect.

The base portion 440 kept above-mentioned guide-lighting aggregate 430 is arranged in the side walls 121 of second housing 120, outstanding to the first shell 110 from the part near front periphery wall 122a.The light-tight partition 442 this base portion 440 being provided with five groove portions 441 and being arranged between groove portion 441, and be respectively equipped with elasticity holding plate 443 at the position of base portion 440 both sides.
Groove portion 441 is the recesses of the nose portion being formed at base portion 440, when luminous leading section 431Ab, 431Bb of light conductor 431A, 431B are configured to relative with display window hole 426, under the state that can fasten at the base end part of the base end part of first row light conductor 431A and secondary series light conductor 431B, they are received.Light-tight partition 442 is parts that part is each other outstanding to the first shell 110 from groove portion 441, and is formed by opaque molding resin material.When the side of light conductor 431A, 431B and groove portion 441 abut against, light-tight partition 442 is formed as giving prominence to each other from light conductor 431A, 431B, and respective front end is in the position near circuit substrate 200.Elasticity holding plate 443 is outstanding to the first shell 110 from the position of base portion 440 both sides, and respective leading section has claw 443a.When the leading section and front periphery wall 122a that are accommodated in light conductor 431A, 431B in groove portion 441 abut against, elasticity holding plate 443 is arranged to abut against with mode light conductor 431A, 431B pressed gently to the inner surface of front periphery wall 122a by connecting elements 432 and connecting elements 432, and by making claw 443a and connecting elements 432 fasten, thus light conductor 431A, 431B can be limited move to the direction leaving groove portion 441.In addition, for structure identical with embodiment 1 in other structure, mark identical label, and description is omitted.
In embodiment 3, when guide-lighting aggregate 430 is installed on base portion 440 of second housing 120, if by luminous leading section 431Ab from after the direction that the inner surface relative to front periphery wall 122a tilts navigates to display window hole 426, be pressed between elasticity holding plate 443 and front periphery wall 122a, slip into from the inclined-plane of claw 443a to make connecting elements 432, then elasticity holding plate 443 bends in the mode leaving front periphery wall 122a, the claw 443a of front end is made to retreat thus, therefore also can when without the need to guaranteeing that housing 100 inside has the space supplying the movement of guide-lighting aggregate 430, whole guide-lighting aggregate 430 is installed in base portion 440.Particularly because be provided with thinner wall section 128 on the periphery wall 122a of front, therefore easily aforesaid operations can be carried out.And, owing to being all arranged on identical second housing 120 by the base portion 440 supported guide-lighting aggregate 430 and the display window hole 426 that is configured with luminous leading section 431Ab, 431Bb, therefore luminous leading section 431Ab, 431Bb can be configured to display window hole 426 exactly.Be arranged on guide-lighting aggregate 430 in the base portion 440 of second housing 120 to be resiliently held with respective light conductor 431A, 431B the mode that plate 443 lifts gently upward and to be clamped between the inner surface of front periphery wall 122a, and fastened by the claw 443a and connecting elements 432 making elasticity holding plate 443, be maintained to make the state stoping the side of light conductor 431A, 431B to leave the movement in groove portion 441.
Therefore, housing 100 is being decomposed into the first shell 110 and second housing 120, or the first shell 110 and second housing 120 is being assembled when forming housing 100, easily can carry out operation.And during carrying out these operations, guide-lighting aggregate 430 can not come off from second housing 120, therefore also can not cause the damage of guide-lighting aggregate 430, lose such problem.And owing to arranging prismatic light conductor 431A, 431B on the direction parallel with circuit substrate 200, the size on therefore orthogonal with circuit substrate 200 direction also can not increase, and can realize the miniaturization of housing 100.In addition, due to two row light emitting diode 420A, 420B can be carried on circuit substrate 200, the length dimension of row can therefore be suppressed.In the case, first shell, 110 pairs of circuit substrates 200 are supported, and display window hole 426 is set on second housing 120, therefore when guide-lighting aggregate 430 is assembled on second housing 120, light emitting diode 420A, 420B can not counteract, even the guide-lighting aggregate 430 of two array structures, also can remain on simply on second housing 120.
When light emitting diode 420A, 420B that circuit substrate 200 carries are lighted, by luminous leading section 431Ab, 431Bb and the annular gap s that forms between luminous leading section 431Ab, 431Bb and the perisporium in display window hole 426, to the outer blaze of housing 100.That is, luminous leading section 431Ab, 431Bb of light conductor 431A, 431B become the first light-emitting area, and the gap s between luminous leading section 431Ab, 431Bb and display window hole 426 becomes the second light-emitting area.Therefore, even if such as production batch is different, the light-emitting area that the first light-emitting area evenly overlaps with the second light-emitting area can also be obtained in multiple display window hole 426.In addition, the light-emitting area of light emitting diode 420A, 420B of observing from front is the aperture area in display window hole 426, by display window hole 426 being set be greater than luminous leading section 431Ab, 431Bb of light conductor 431A, 431B, thus can improve light emitting diode 420A, 420B light visuality.And, when display window hole 426 being set larger than luminous leading section 431Ab, 431Bb of light conductor 431A, 431B, also tool has the following advantages: namely, when guide-lighting aggregate 430 is installed to base portion 440, the operation making luminous leading section 431Ab, 431Bb navigate to display window hole 426 from oblique direction becomes comparatively easy.And for display window hole 426, be greater than the trapezoidal of the inner surface of front periphery wall 122a owing to being formed as outer surface aperture area, therefore, the slip changing light-emitting area during sight line is suppressed, and improves the visuality of light emitting diode 420A, 420B.
In addition, in guide-lighting aggregate 430, between first row light conductor 431A and secondary series light conductor 431B, connecting elements 432 is provided with.Therefore, the light leak produced to each other from light conductor 431A, 431B is inhibited, when therefore such as another light emitting diode 420A, 420B being extinguished when making adjacent light emitting diode 420A, 420B in each row light, can confirm that another light emitting diode 420A, 420B are in OFF state exactly.
And, when the side of light conductor 431B and groove portion 441 abut against, the light-tight partition 442 by opaque resin forming materials is arranged to give prominence to each other from light conductor 431A, and respective front end is in the position near circuit substrate 200.Therefore, light conductor 431A, 431B can not only be remained in base portion 440 with stable state, the direct light leak between light conductor 431A, 431B adjacent in each row can also be suppressed, can also place cause because of the reflection from circuit substrate 200 in first row light conductor 431A from a light conductor 431A to the roundabout light leak of another light conductor 431A.
In addition, above-mentioned embodiment 3 is passed the imperial examinations at the provincial level the trapezoidal situation being illustrated and display window hole 426 being formed as outer surface aperture area and being greater than the inner surface of front periphery wall 122a, but it is equal with outer surface aperture area also display window hole shape can be become inner surface aperture area.In addition, although be provided with circular display window hole 426, the opening shape in display window hole 426 is not limited only to circle, can also be arbitrary polygon.Section shape for luminous leading section 431Ab, 431Bb is also identical, can be arbitrary polygon.Therefore, if such as change the opening shape in display window hole 426 according to the classification kind of displaying contents, then can obtain light emitting diode 420A, 420B color distinguish beyond means of identification.But, no matter what kind of combination is carried out to the section shape of the shape in display window hole 426 and luminous leading section 431Ab, 431Bb, if consider light-emitting area, then preferred surrounding between luminous leading section 431Ab, 431Bb and display window hole 426 guarantees gap s.
In addition, about the end surface shape of luminous leading section 431Ab, 431Bb, plane or spherical can be adopted, but be preferably set for can not be outside outstanding to housing 100 from display window hole 426 dimensional tolerance.If luminous leading section 431Ab, 431Bb are not projected into the outside of housing 100, then not only the outside cleaning of housing 100 becomes comparatively easy, also can prevent in advance to cause damage when cleaning to luminous leading section 431Ab, 431Bb, or due to inappropriate pressing cause the elasticity holding plate 443 of base portion 440, the connecting elements 432 of guide-lighting aggregate 430 damages.
In addition, because the some light of secondary series light emitting diode 420B is injected from straight parts 431Ba, therefore light conductor 431B not necessarily will adopt prismatic, also can adopt cylindrical.But, when adopting cylindrical light conductor 431B, preferably the groove portion 441 of base portion 440 is also configured to the recess of semicircular arc.
