The central portion of button equipped section 10a is offered circular hole 10d, owing to driving projection 9a to run through this circular hole10d, rubber bodies 10 is installed in the back side one side of button support 9. And, the 10b of pair of angled support sectorCardinal extremity separately near offer respectively installing hole 10e, because 2 engagements foot 3a of front panel 3 run through respectivelyThese 2 installing hole 10e, rubber bodies 10 covers light conductor 11 and is installed to assigned position. In addition, at figureWhen not operation shown in 2, the 10b of pair of angled support sector is by button support 9 Hes on the 10a of button equipped sectionOperation push-button 1 remains on the off position of regulation.
As shown in Figure 2, in light conductor 11 inside, reflecting surface 11c is set, by the light from a side 11b incidentAlignment light emergence face 11a reflection, by form jog, rake on this reflecting surface 11c, realize fromLight emergence face 11a penetrates the few light of briliancy spot. In the present embodiment, light conductor 11 is fixed on flexibleWiring substrate 5 and being covered by rubber bodies 10, light emergence face 11a is relative with the back side of rubber bodies 10. And,A side 11b of light conductor 11 is relative with light source LED8 with irradiation. In addition, this light conductor 11 is provided with:Make through hole 11d that the driving projection 9a of button support 9 inserts, in order to suppress strong to light emergence face 11aStrong light is reflected in by a side 11b(LED8) region be provided with through hole 11e.
Secondly, for possessing these operation push-buttons 1 and button support 9, rubber bodies 10, light conductor 11 etc.The action of press button mechanism 20 describe. When user is by the operating surface of operation push-button 1 (key-top)1a presses to inside, and strain occurs for the 10b of inclination support sector of rubber bodies 10, and bulge 10c withAfter connecting, light conductor 11 also there is strain, button support 9 and operation push-button 1 and button equipped section10a moves to inside together. Then, when operation push-button 1 is carried out the pressing operation of regulation pressing quantity, buttonThe driving projection 9a of support 9 presses driving switch element 6 makes it carry out " opening " action. And, described inWhile removing user's operating physical force after pressing operation, due to the 10b of inclination support sector and bulge 10c selfElasticity and return to the shape of beginning, be mounted in the button support 9 of button equipped section 10a and operation byWhen key 1 is pushed back to off position (primary position), switch element 6 also automatically restores to " pass "State.
In this press button mechanism 20, in order to improve the visuality of operation push-button in the dim environment such as night,The light penetrating from LED8, reflected by the reflecting surface 11c of light conductor 11 is propped up by rubber bodies 10 and buttonHold body 9 and be irradiated to the back side (quadrangular pyramid face 1c) of operation push-button 1, the operating surface 1a of operation push-button 1 accordinglyCarried out irradiation. At that time, see through between light that translucent rubber bodies 10 and button support 9 be diffused passes throughGap C is irradiated to the quadrangular pyramid face 1c of operation push-button 1 after further spreading, so be irradiated to this quadrangular pyramid faceThe light of 1c is exactly the few light of briliancy spot.

Thus, the light that briliancy spot is few is irradiated to4 inclined plane 1c1～1c4 of the quadrangular pyramid face 1c of formation operation push-button 1 are upper, before operation push-button 1Operating surface 1a mono-side can penetrate the different gradient and pointing to separately along with these inclined planes 1c1～1c4The light that characteristic is different. As a result, this operation push-button 1 not only can be at the quadrangular pyramid that can see the back side one sideUnder the state of face 1c, make its irradiation, and due to the 1st inclined plane 1c1,1c2 and the 2nd inclined plane 1c3,1c4Luminance difference, the luminous place of operation push-button can along with user's visual angle, great changes will take place. ByCan be analogized the senior luminance for jewels such as crystals in special so new-type irradiation sample state, will be producedThe effect that raw operation push-button irradiation grade significantly improves. And operation push-button, button support can be by thoroughlyPhotosensitiveness ester moulding is desirable shape, can not produce the phenomenon raising the cost.
And, in the button irradiation structure of present embodiment, also adopted the upper formation of reflecting surface 11c concavo-convexThe light conductor of portion, rake, by the light of the LED8 of the side incident from this light conductor 11 by reflecting surface 11cReflection guiding leaning front one side, penetrates briliancy spot from the light emergence face 11a relative with the back side of rubber bodies 10 fewLight. Therefore, see through light conductor 11, rubber bodies 10 and button support 9 and be irradiated to operation push-button 1The briliancy spot of the light at the back side (quadrangular pyramid face 1c) becomes considerably less, thus operation push-button 1 during by irradiation moreEasily make this quadrangular pyramid face 1c become noticeable.
And, in the button irradiation of present embodiment structure, by and the quadrangular pyramid face 1c of operation push-button 1 betweenThe opposite face that leaves the button support 9 that clearance C is oppositely arranged is set as contrary with quadrangular pyramid face 1c concavo-convex relationshipQuadrangular pyramid face 9b, thereby make two quadrangular pyramid face 1c, 9b of operation push-button 1 and button support 9Relative spacing equates everywhere. Therefore,, in the time of irradiation, form each inclination of the quadrangular pyramid face 1c of operation push-button 1Crest line 1d between face can become very obvious, thereby while also making irradiation, user more easily sees quadrangular pyramid face 1c.But the opposite face of button support 9 also there is no need to be necessarily arranged to the pyramidal plane of operation push-button 1Shape is identical, for example, also can form the flexure plane relaxing along pyramidal plane, so also can be in certain journeyOn degree, make size (relative spacing) homogenization of clearance C.
And, in the button irradiation structure of present embodiment, the top of the quadrangular pyramid at the back side of operation push-button 1The dead astern of some 1b position rectangular operation face 1a central authorities, while seeing operation push-button 1 from front, the rib of this quadrangular pyramidLine 1d is positioned at cornerwise dead astern of operating surface 1a, so have good visual balance. Therefore, behaviourMake the complexity especially that the shape of button 1 needn't design and also can increase substantially irradiation grade.
In addition, the situation that in the above-described embodiment back side of operation push-button 1 is formed as to quadrangular pyramid face is carried outExplanation, still, also can arrange according to the size of the operating surface 1a of operation push-button 1, shape back side shapeBecome pyramidal beyond quadrangular pyramid, for example, also can be arranged to the polygonal cone-shaped of pentagonal pyramid, anistree cone etc.And, also the back side shape of operation push-button 1 can be arranged to pyramidal towards a side on the front of summit,Now the back side one side of operation push-button 1 has the recess being formed by this pyramidal plane. And only at operation push-button 1The part at the back side form pyramidal plane and also may produce the effect that improves irradiation grade.
