In addition, switch 40 constitutes by applying movable contact unit 36 on the circuit board 5 that disposes fixed contact 6 and light-emitting component 27,28.At this, be configured to: constitute on the outside fixed contact 6b of periphery on circuit board 5 of travelling contact 3 of movable contact unit 36, the following central 3a of travelling contact 3 separates predetermined gap with central fixed contact 6a and relative.
And the switch 40 of Gou Chenging for example is built in portable telephone shown in Figure 3 45 like this.As shown in Figure 3, switch 40 shown in Figure 1 is built in the stationary housing 51 of doubling formula portable telephone 45, and this doubling formula portable telephone 45 possesses dialing button 55, action button 56 and microphone 57.The 1st light conductor (not shown) is built in the position of the rectangle 41 that is represented by dotted lines, and is set in the 2nd light conductor (not shown) quilt to be positioned at the position shown in the polygon 42 that is represented by dotted lines.In addition, central fixed contact 6a, outside fixed contact 6b and light- emitting component 27,28 Jie are electrically connected on the electronic circuit (not shown) of equipment by wiring figure (not shown).And stationary housing 51 is connected in the mode that can fold with movable housing 52, and this movable housing 52 has loudspeaker 53 and display part 54 at the mask that joins with stationary housing 51.
In addition, dialing button 55, comprise: lower end shown in Figure 1 be positioned at travelling contact 3 central portion 3b the top and be connected to the top transmittance section 55a of the 2nd light conductor 22, cover the top light shielding part 55b of dialing button 55 and the display part 55c that transmittance section 55a exposes with the shape of literal, mark etc.
In addition, action button 56 comprises roughly ring-type and the ring-type operating portion 58 that can swing all around and in the medium pore of ring-type operating portion 58 and the circular operating portion 59 that can move up and down.
At this, ring-type operating portion 58 comprises that the lower end is connected to the top transmittance section 58a of the 1st light conductor 21 of central portion 3b of travelling contact 3 and the light shielding part 58b that joins with transmittance section 58a.In addition, circular operating portion 59 comprises: the lower end is connected to the top transmittance section 59a of the 1st light conductor 21 of central portion 3b of travelling contact 3 and the light shielding part 59b that joins with transmittance section 59a.
In above formation, if push dialing button 55 downwards, then the lower end of the transmittance section 55a at this place push the 2nd light conductor 22 above.Thus, the 2nd light conductor 22, substrate 2 deflections, the central portion 3b of the general dome shape of travelling contact 3 is pressed.In addition, when the central portion 3b at travelling contact 3 applies predetermined pressing force, travelling contact 3 is followed click clatter (click, click) feels elasticity counter-rotating downwards, the following central 3a of travelling contact 3 contacts central fixed contact 6a, and central thus fixed contact 6a and outside fixed contact 6b become the state that Jie is electrically connected by travelling contact 3.
Then, when the pressing force removed dialing button 55, since elastic restoring force, travelling contact 3 elasticity counter-rotating upward.So, the following central 3a of travelling contact 3 leaves central fixed contact 6a, and central fixed contact 6a and outside fixed contact 6b become the state that electricity disconnects.
Similarly, in ring-type operating portion 58, when left and right sides either direction is pushed the outer rim of ring-type operating portion 58 forwards, backwards, be situated between by the travelling contact 3 corresponding to the direction of having pushed, central fixed contact 6a and outside fixed contact 6b become the state of electrical connection.In contrast, under situation about having removed the pressing force of ring-type operating portion 58, central fixed contact 6a and outside fixed contact 6b become the state that electricity disconnects.In addition, under the situation of having pushed circular operating portion 59, similarly, fixed contact 6a of central authorities and outside fixed contact 6b become the state that Jie is electrically connected by travelling contact 3, on the other hand, removing under the situation of pushing, central fixed contact 6a and outside fixed contact 6b become the state that electricity disconnects.
The state that central fixed contact 6a like this and outside fixed contact 6b are electrically connected or electricity disconnects detects by electronic circuit (not shown).And, by this electronic circuit, to the 1st light-emitting component 27 shown in Figure 1 or the 2nd light-emitting component 28 supply powers.
When supply power made that the 1st light-emitting component 27 is luminous, the light that sends from the 1st light-emitting component 27 was advanced while reflect to left in the 1st light conductor 21 from the right-hand member incident of the 1st light conductor 21.This light of advancing is by 23 diffusions of top irradiation portion, the reflection of light conductor 21, and light is by the transmittance section 58a of ring-type operating portion 58 and the transmittance section 59a of circular operating portion 59.Consequently, from the light of the 1st light-emitting component 27 above below irradiation ring-type operating portion 58 and circular operating portion 59.
Then, concavo-convex owing on the 1st light conductor 21, being provided with near slit 24 as decay portion 25, so the light of in the 1st light conductor 21, advancing diffusion to left.Thus, light above this decay portion 25 to outside diffusion, be reflected, so decay by decay portion 25 from the light of the right-hand member incident of the 1st light conductor 21.
Because the light that sends from the 1st light-emitting component 27 is decayed in this wise, so almost do not have light to reveal from the end in the left side of the 1st light conductor 21.In addition owing to be provided with slit 24, so even reveal the light of a little from the end in the left side of the 1st light conductor 21, while this light also can spread scattering in air, so can prevent the surface feeding sputtering of light from the 2nd light conductor 22.
On the other hand, by electronic circuit (not shown) to the 2nd light-emitting component 28 supply powers, under the luminous situation of the 2nd light-emitting component 28, similarly, be incident in the 2nd light conductor 22 from the light of the left end incident of the 2nd light conductor 22, advance while in the 2nd light conductor 22, reflect to right-hand.The light that this is advanced, the irradiation portion 23 on the 2nd light conductor 22 is by diffusion, reflection, from below irradiation transmittance section 55a.At this moment, light is by 23 reflections of irradiation portion or diffusion, so the optical attenuation that the 2nd light-emitting component 28 sends.
And then, the light of in the 2nd light conductor 22, advancing, after by 23 diffusions of a plurality of irradiation portion, near the decay portion 25 right-hand member is by diffusion, reflection, so can almost eliminate the light of revealing from the right-hand member of the 2nd light-emitting component 28.In addition, even for example reveal the light of a little from the end on the right side of the 2nd light conductor 22, because slit 24, light also can spread in air, so can prevent light incident in the 1st light conductor 21.
Thereby, can prevent that light is revealed to the 2nd light conductor 22 between the 1st light-emitting component 27 light emission periods, in addition, can prevent that light is revealed to the 1st light conductor 21 between the 2nd light-emitting component 28 light emission periods.Thus, can avoid between the 1st light-emitting component 27 light emission periods the top illuminated light of the dialing button 55 of the 2nd light conductor 22 sides.On the other hand, can avoid between the 2nd light-emitting component 28 light emission periods the top illuminated light of the action button 56 of the 1st light conductor 21 sides.
That is,, decay fully by the light shielding part 26 that constitutes by slit 24 and decay portion 25 from the light that light-emitting component 27,28 sends.Thereby, avoid the top illumination of sending of dialing button 55 to penetrate by light shielding part 26 by light-emitting component 27, avoid the top illumination of sending of action button 56 to penetrate by light shielding part 26 by light-emitting component 28.
In addition, also has following effect: even if for example the 1st light-emitting component 27 uses red light-emitting component light-emitting component luminous, that 28 uses of the 2nd light-emitting component are white luminous, by such light shielding part 26 is set, also can constitutes and avoid in the 1st light conductor 21 and the 2nd light conductor 22, mixing each light.
Such switch of the present invention is being used under the situation of portable telephone for example, when in the doubling formula portable telephone 45 at Fig. 3 during operating operation button 56, for example Hong Se the 1st light-emitting component 27 is luminous, the light that sends is leaded light in the 1st light conductor 21, by 23 diffusions of irradiation portion, action button 56 irradiations are redness.
In addition, when operation dialing button 55, for example Bai Se the 2nd light-emitting component 28 is luminous, and the light that sends is leaded light in the 1st light conductor 21, similarly by the light by 23 diffusions of irradiation portion, dialing button 55 irradiations is white.
At this, the irradiation of action button 56 and dialing button 55 is independent of each other, can not appear at the light that different light conductors advances reveal, by the situation that the user sees, can not occur that light mixes and the situation of being seen yet.Thus, can realize various irradiation that the combination of action button 56 and dialing button 55 is carried out.
In addition, in the above description, the top situation that decay portion 25 and irradiation portion 23 is present in the 1st light conductor 21 and the 2nd light conductor 22 is illustrated, but below also can being arranged at.Under the situation below being arranged at, same light also reflects, spreads in the position of decay portion 25 and irradiation portion 23, and is arranged at top situation similarly obtains to cut off light between the 1st light conductor 21 and the 2nd light conductor 22 effect.
In addition, even if slit 24 is only arranged or decay portion 25 is only arranged, also can obtain between the 1st light conductor 21 and the 2nd light conductor 22, to cut off the effect of light as light shielding part 26.Yet,, can more effectively between the 1st light conductor 21 and the 2nd light conductor 22, cut off light by also using them.
In addition, in the above description, illustrated that near the decay portion 25 of end face of the 1st light conductor 21 and the 2nd light conductor 22 passes through the situation that printing forms.Yet, also can irregular metal mould etc. be pushed near the end face, (punching press) processing of pressurizeing with being provided with, make thus to constitute the concavo-convex of decay portion 25.
In addition, in the above description, slit 24 situation with the setting of コ word shape between the 1st light conductor 21 and the 2nd light conductor 22 is illustrated.Yet the shape in slit 24 is not limited to the コ word shape, for example constitutes the 1st light conductor 21 and the 2nd light conductor 22 and is rectangle and separates configuration, form slit 24 etc. betwixt, also can carry out enforcement of the present invention.
According to such present embodiment, the light shielding part 26 of slit 24, decay portion 25 etc. is set between the 2nd light conductor 22 of the 1st light conductor 21 of transmitance and transmitance.Thus, can avoid the irradiation portion 23 of each light conductor by the illumination of revealing from the opposing party's light conductor penetrate ground, with the irradiation portion 23 of different each light conductors of pulsed exposure.In addition, even if light-emitting component 27, the 28 luminous colors at each light conductor of irradiation are under the situation of different colours, also can avoid each blend of colors, thus can provide constitute simple, can carry out the light guide sheet of various irradiation, the movable contact unit of having used this light guide sheet and switch.
