Embodiment
The present invention also can be suitable for for each key top monomer certainly, but mostly implements as the key plate of the sheet on a plurality of keys of integrated support top.Its reason be because, these a plurality of keys tops are sticked on the key plate by transparent adhesives, when device fabrication, because can be as assembly and integrated processing, so operation and built-up time when shortening the equipment on the subsidiary key of assembling top bring great effect.
Fig. 1 (a) is the figure of example that the mobile phone 2 of keyway 1 of the present invention has been made up in expression, the state of the keyway 1 when representing not illumination (can see mode).Mobile phone 2 is except liquid crystal display picture 3 and housing parts, and promptly the whole surface of keyway 1 metallochrome of glossiness silver color etc. of as seen glimmering be can't see the shown literal of each key surface, symbol etc.
Fig. 1 (b) is identical with Fig. 1, the state of expression keyway 1 when illumination, represented is on each key top 4 by the hollow out literal show numeral 0～9 and alphabet literal a～z and symbol * ,+, the state of # etc. (penetrate light from the surface on each key top 4 and the shape of respectfully presenting literal etc., become the state that literal etc. can identification that makes).The key of some is " having four directionkeys 5 of determining key " greatly.This key 5 is to have definite key part in central authorities, has around it by the key of the four directions shown in the △ arrow to indication.
In Fig. 1 (b) of the state of the keyway of expression during illumination, it is black why the part beyond the hollow out literal on each key top 4 looks like, be not because by black.The illusion effect that these other parts that are schematization ground shows the hollow out word segment of light ejaculation and do not have light to penetrate produce in contrast.
Fig. 2 (a) is the vertical view of keyway 1, is illustrated in the key top 4 that rectangular ground disposes side by side on the reinforcement plate 21.Reinforcement plate 21 is plate bodys of polycarbonate resin (PC) or stainless steel (SUS) system, has a plurality of through holes.The frame of broken lines of the maximum that is surrounded by dotted line represents to increase a plurality of through holes 22 that run through on the plate 21, is represented to insert the part of the key plate 23 in the through hole 22 by the part of surrounding than its little frame of broken lines.Its central dashed circle is to press son 24 (being used for the action on key top is passed to the extruding projection of contact).
Fig. 2 (b) is the figure that sees reinforcement plate 21 from the back side.The part that is illustrated by the broken lines in Fig. 2 (a) is represented that by solid line the part of being represented by solid line is illustrated by the broken lines.
Fig. 3 (a) is the part enlarged drawing of keyway 1 of the present invention, and Fig. 3 (b) is the enlarged drawing of A-A line section.In Fig. 3 (b), the part that is positioned at dome (dome) shape of the below of pressing son 24 is the switch (contact) 25 of work when pressing son 24 mobile downwards.In this figure, what represented by thick slightly horizontal line at the downside on adjacent key top 4 is diaphragm 26.The effect of diaphragm 26 is to prevent to leak upward from the gap on the key top 4 of adjacency in the illumination time.
Fig. 4 is the part amplification profile on key top 4, and further amplifies the part of being surrounded by that circle, is presented at the figure of the state of the coating of being implemented on the key top 4.Key top 4 transparent materials by for example resin, glass etc. form.
Film formation process for key top 4 is that the positive and negative on key top 4 is put upside down, by its back side being formed 40 beginnings of characters cut in intaglio (hollow out literal) printed layers.Form colourless or coloured light transmission printed layers 40a then thereon, openwork part 40a is filled by this material.Then, remove positive and negative reverse, the surface on key top 4 is applied priming coat 41 (undercoat), form metallic film (half-reflecting mirror) 42 thereon.
As metallic film (half-reflecting mirror) 42 usefulness the example of kind of the metal that can use, but illustration is as aluminium, titanium, chromium, iron, nickel, copper, zinc, zirconium, molybdenum, silver, indium, tin, tungsten, platinum, the monomer of gold or their alloy etc.
Metallic film (half-reflecting mirror) 42 is by physical vapor deposition (PVD), for example: the film build method of vacuum evaporation, molecular beam epitaxy evaporation (MBE), ion plating, ion beam evaporation, conventional sputter (conventionalsputtering), magnetron sputtering (magnetron sputtering), ion beam sputtering, ECR sputter or the like forms.This is called as " half-reflecting mirror bands " below method.
The example of thickness that half-reflecting mirror bands the metallic film 42 of layer is, is 5nm～35nm as material under the situation of aluminium using, and in fact also can be 10～30nm.
On metallic film (half-reflecting mirror) 42, also be coated with inter coat 43, last Masking apparatus for coating finishing coat (overcoat) or surface layer (topcoat) 44.It is not water white banding the overlay coating 44 that applies on the layer for half-reflecting mirror, but colored transparent, can reach various colors thus.
If the material of each coating of example is then for as follows: it is adhesive that priming coat 41 can be selected acrylate (acrylate); It is adhesive that inter coat 43 can be selected ethene; Overlay coating 44 can be selected acrylic ester adhesive etc.
If the thickness of each coating of example, then priming coat 41 is 8～10 μ m; Inter coat 43 is 8～10 μ m; Overlay coating 44 is 18～20 μ m.
In addition, not using above-mentioned film build method to implement alternative scheme of the present invention shows as follows.Promptly, example as alternative scheme, be to utilize brand (hot stamp) to traverse whole face in bottom surface, key top to paste metal forming, carry out comprehensive application and printing (better) comprehensively from it, by common hollow out text printout and laser marking (laser marking) remove a part of filming and form hollow out literal (symbol, figure) etc. thereafter.In other alternative schemes, also can on metal forming, form text printout layer (characters cut in relief, symbol, figure etc.), light is penetrated from parts in addition such as literal.
The back side on key top 4 is formed with hollow out literal (characters cut in intaglio) or characters cut in relief printed layers 40.For the hollow out literal, the situation for painted and overlapping dyed layer is arranged also.
Also consider not make half-reflecting mirror (banding layer) 42 directly to be formed at the surface on key top 4, but only on the surface or the single face at the back side form half-reflecting mirror (banding layer) 42 and text printout layer 40 etc. in the lump.
In order not make half-reflecting mirror (band layer) 42 directly be formed at the surface on key top 4, also can adopt the method for (in mold) drawing and forming in the mould for example etc., use the film that is formed with half-reflecting mirror (banding layer).
This example that forms the necessity of overlay coating 44 about the surface on key top 4 is illustrated.Very thin of the metal epithelium that generates by sputter and vapor deposition treatment.Have again, in employed metal, because the chemical change of oxidation etc., also have metal epithelium get rusty variable color and damaged possibility.Particularly the time with the so soft metal of aluminium, also think because the interference of friction etc., can cause scar and cause peeling off epithelium.
Therefore, for utilize outside chemical, physical property be used for protecting sputtered film and vapor-deposited film, can implement to be called as the operation that overlay coating (or overcoat) 44 is handled.Overlay coating 44 is that so-called cover lacquer (clear lacquer) this transparent coating gets final product.The same with priming coat 41, by being coated with, hardening with the identical operation of application.Here the application of handling as overlay coating, known method has, and for example applies yellow overlay coating on the sputtered aluminum film of silver color, presents the outward appearance of gold thus.
Use aforesaid material, use aforesaid method, the reason that the metallic film that forms by aforesaid coating layer thickness produces the half-reflecting mirror effect is owing to forming the gap that produces between the metallic of thin layer.
In example shown in Figure 1 of the present invention, considered various distortion.The illustration of Fig. 5 is whole layers to be located at the second top embodiment on key top 4.At first, on key top 4, form the priming coat 41 (pure color (solid color) layer) of white, form hollow out literal (characters cut in intaglio) printed layers 40 by for example silk screen printing thereon.
If form colourless or coloured light transmission printed layers 40a thereon, then the part 40a of hollow out will be filled by this material then.On form metallic film (half-reflecting mirror) 42, form inter coat 43, overlay coating 44 more successively to protect the surface.Again by following directly adhere to key plate 23 on of the bright adhesive phase 27 of show with key top 4.
The illustrative embodiment of Fig. 6 is the 3rd following embodiment that whole layers is located at key top 4.At first, put upside down the positive and negative on key top 4, side applies priming coat 41 below, forms hollow out text printout layer 40 by thin metal layer (half-reflecting mirror) 42.Secondly, adhere to colourless or coloured light transmission printed layers 40a according to the shape of filling the hollow out literal.Adhere on the key plate 23 by transparent adhesive layer 27 then.
So under this routine situation, the top of key top 4 do not form any layer.Need not to form responsible protected key in other words and push up the overlay coating on 4 surfaces.
The illustrative embodiment of Fig. 7 is in the example of text printout (positive), whole layers is located at the 4th top embodiment on key top 4.On key top 4, at first form priming coat 41, form the text printout layer (positive) 40 of non-light transmittance thereon, adhere to colourless or coloured light transmission printed layers 40a reaching periphery on this layer.Direct thereon or folder is removing metallic film 42 every priming coat, forms after the inter coat 43, implements overlay coating 44 at last to protect the surface.
Below key top 4, do not form any layer.(only adhering on the key plate 23 by transparent adhesive layer 27) afterwards.During illumination under this embodiment situation, whole by the color illumination key top of coloured light transmission printed layers, wherein the demonstration of literal etc. is dark.
The illustrative embodiment of Fig. 8 be in the example of text printout (positive) all layer be located at the 5th embodiment below the key top 4.At first, put upside down the positive and negative on key top 4, side applies priming coat 41 in its lower section, forms thin metal layer 42 thereon, forms text printout (positive) 40.Secondly, adhere to colourless or coloured light transmission printed layers 40a according to the shape of filling the hollow out literal.Adhere on the key plate 23 by transparent adhesive layer 27 then.
So under this routine situation, the top of key top 4 do not form any layer.Need not to form responsible protected key in other words and push up the overlay coating 44 on 4 surfaces.Identical when watching literal etc. during illumination under the situation of this embodiment with the cardinal principle of described embodiment 4.
