Embodiment
For making there is further understanding to object of the present invention, structure, feature and function thereof, embodiment is hereby coordinated to be described in detail as follows.
Please refer to Figure 1A and Figure 1B, Figure 1A is that the cutaway view be arranged in keycap 150, supporting mechanism 160 and base plate 170 according to the elastomer layer of one embodiment of the invention is (graphic too complicated for avoiding, base plate 170, keycap 150 and supporting mechanism 160 are all represented by dotted lines), Figure 1B is the upward view of Figure 1A elastomer layer.Elastomer layer 100 at least comprises transparent substrates 110, elastomer 120, solid.Wherein solid can be: the material printing opacity of (1) solid, and wherein doped with indicator 140, or the material of (2) solid itself is light tight, and solid inherently has color.
Transparent substrates 110 is such as mylar film (mylar) or film circuit board.Transparent substrates 110 is such as thin film switch layer.For example, transparent substrates 110 can comprise the first film 111, second film 112, wall 113, first electric conductor 114 and the second electric conductor 115.Wall 113 between the first film 111 and the second film 112, and has perforate 113a.First electric conductor 114 is formed on the first film 111, and the second electric conductor 115 is formed on the second film 112, and the first electric conductor 114 and the second electric conductor 115 are oppositely disposed.First electric conductor 114 perforate 113a corresponding to the position of the second electric conductor 115.Elastomer 120 deformation can be driven when keycap 150 is subject to pressing, the elastomer 120 of deformation applies pressure to transparent substrates 110, first electric conductor 114 and the second electric conductor 115 are electrically connected through perforate 113a, and through the circuit output key signal that transparent substrates 110 connects.Supporting mechanism 160 is arranged between keycap 150 and transparent substrates 110, and be movably connected keycap 150 and transparent substrates 110, makes keycap 150 can be up and down relative to transparent substrates 110 (that is relative to elastomer layer 100).
Transparent substrates 110 has relative transparent substrates upper surface 110u and transparent substrates lower surface 110b.Owing to forming the first film 111, second film 112, wall 113 all light-permeables of transparent substrates 110, therefore light can penetrate transparent substrates, freely advances between upper surface 110u and lower surface 110b.
Elastomer 120 is arranged at above transparent substrates 110.Elastomer 120 has elastomer lower surface 120b, and elastomer lower surface 120b has default adhesioin zone R1.The elastomer 120 of the present embodiment is by being formed by light transmissive material, and so the light of top light source can penetrating projectile gonosome 120 and irradiating through printing opacity solid 130, and then light continues downwards travel across transparent substrates 110 and be observed again.
As long as printing opacity solid 130 light-permeable, the embodiment of the present invention does not limit the light transmittance of printing opacity solid 130.In one embodiment, the light transmittance of printing opacity solid 130 can be 40% to 100%.Under this range of transmittance, light can penetrate printing opacity solid 130 and be irradiated to indicator 140, makes indicator 140 inspire the light with predetermined wavelength.In addition, under above-mentioned range of transmittance, the light of what indicator 140 inspired have predetermined wavelength can demonstrate the dispensing area of printing opacity solid 130 completely, so that observe the coating situation of printing opacity solid 130.
Printing opacity solid 130 is formed between elastomer lower surface 120b and transparent substrates 110.In one embodiment, printing opacity solid 130 can adopt screen painting to be formed on transparent substrates 110, and then elastomer 120 is bonded on printing opacity solid 130 again, with the relative position between fixing elastomer 120 and transparent substrates 110.Printing opacity solid 130 occupies dispensing area R2 on transparent substrates 110.The area of dispensing area R2 can be more than or equal to the area of default adhesioin zone R1, and dispensing area R2 is overlapping at least partly with default adhesioin zone R1.When whole default adhesioin zone R1 is overlapped in dispensing area R2 completely, represent that elastomer 120 is excellent with the then situation of transparent substrates 110; When the part that default adhesioin zone R1 and dispensing area R2 is underlapped exceedes certain area, represent that part elastomer lower surface 120b is not bonded in printing opacity solid 130, so may cause the adherence of elastomer 120 and transparent substrates 110 deficiency or not meet expection.
Indicator 140 is doped in printing opacity solid 130.Through indicator 140, the then good and bad degree of observable elastomer 120 and transparent substrates 110.Specifically, because the transparent substrates 110 of the present embodiment, elastomer 120 and printing opacity solid 130 all have light transmission, light penetration elastomer 120 and printing opacity solid 130 can be made, and be irradiated to indicator 140.Indicator 140 is for having the fluorescer of specific wavelength.When the light with specific wavelength is irradiated to indicator 140, the light that indicator 140 can send predetermined wavelength penetrates transparent substrates 110, makes the light of predetermined wavelength demonstrate dispensing area R2 in transparent substrates lower surface 110b.By the overlapping relation of the dispensing area R2 demonstrated, observable dispensing area R2 and default adhesioin zone R1, and then observe the then good and bad degree of elastomer 120 and transparent substrates 110.Above-mentioned specific wavelength can be a wherein wavelength of the wave band belonging to invisible light, so, when the light of other wave band is irradiated to indicator 140, indicator 140 can be avoided to send predetermined wavelength light and go to affect the pattern displaying (when keycap 10 is for light penetrating type keycap) of keycap 150.
In another embodiment, indicator 140 can be dyestuff.Under this design, as long as light is visible ray, just can demonstrate the distribution of dyestuff, demonstrate the distribution of dispensing area R2 by this, and then observe the overlapping relation of dispensing area R2 and default adhesioin zone R1.So, observable goes out the then good and bad degree of elastomer 120 and transparent substrates 110.
As shown in Figure 1A, elastomer 120 comprises the block 121 and annular pin 122 that are connected.Printing opacity solid 130 bonds annular pin 122 and transparent substrates 110.Block 121 has at least one escape hole 121a, and escape hole 121a is communicated with the inside of elastomer 120 with extraneous, escapes to outside elastomer 120 to make the air permeable escape hole 121a of elastomer 120 inside.So, the elasticity of elastomer 120 can be avoided to be subject to the impact of air and to reduce.In another embodiment, escape hole 121a also can run through annular pin 122.As shown in Figure 1B, dispensing area R2 is closed ring, and compared to open annular, the printing opacity solid 130 in closed ring can contain more manifold elastomer lower surface 120b.
Please refer to the cutaway view that Fig. 2 A and Fig. 2 B, Fig. 2 A is the elastomer layer according to another embodiment of the present invention, Fig. 2 B is the upward view of Fig. 2 A, and wherein Fig. 2 A is the cutaway view of Fig. 2 B along direction 2A-2A '.Elastomer layer 200 comprises transparent substrates 110, elastomer 120, printing opacity solid 130 and indicator 140.
With above-mentioned elastomer 120 unlike, the elastomer 120 of the present embodiment projects and has projected centre point C1 on transparent substrates 110, and dispensing area R2 is several line segments R21, and this little line segment R21 essence is distributed in projected centre point C1 surrounding symmetrically.For example, line segment R21 can be arc, and this little line segment R21 is spaced.Interval A1 between several sections of line segment R21 can be used as escape hole, the interval A1 between the air permeable number section line segment R21 of elastomer 120 inside is escaped to outside elastomer 120, reduces to avoid the elasticity of elastomer 120 to be subject to the impact of air.Under this design, elastomer 120 alternative of the present embodiment omits escape hole 121a.In another embodiment, line segment R21 is not limited to camber line, also can be the curve beyond straight line or arc.
