＜effect 〉
Adopt the keyboard 10A of above such formation, as the manufacture method of the carried terminal 100 and the keyboard 10A of electronic equipment, in the recess 24A of thin plate compact 20A, inject thermosetting resin, then, the sclerosis by thermosetting resin forms elastic resin hardenite 30A.At this, in the recess 24A of thin plate compact 20A, be filled under the situation of ultraviolet curing resin, because the contraction (shrinkage cavity) when forming UV hardening of resin body 30B by ultraviolet irradiation, the rear side of key head 50B (keyboard 10B) becomes the such distortion of concavity and for example take place easily.But, make keyboard 10A by in recess 24A, injecting thermosetting resin as described above, can reduce the contraction (shrinkage cavity) when making the thermosetting resin sclerosis.By like this, can be suppressed at keyboard 10A and go up the generation warpage.
In addition, using ultraviolet curing resin to form under the situation of UV hardening of resin body 30B, need be used to reduce above-mentioned contraction (shrinkage cavity) countermeasure, be used for after ultraviolet irradiation, making the operation of dimensionally stable etc., thereby operation becomes complicated.But, owing to the contraction (shrinkage cavity) that can reduce as described above when making thermosetting resin sclerosis form elastic resin hardenite 30A, therefore, compare, can reduce the man-hour when making keyboard 10A with the situation of using ultraviolet curing resin to form UV hardening of resin body 30B.
In addition, in the keyboard 10A of this example, Du sieve's hardometer D hardness of elastic resin hardenite 30A be 50 the degree～80 the degree scopes in the time, even pushing this elastic resin hardenite 30A and forming under the situation of depression, also can prevent from thin plate compact 20A, to produce the damage that causes by plastic deformation with for example such hard thing of finger nail.That is to say, under the elastic resin hardenite 30A situation that too softness and deflection are big, deflection among the thin plate compact 20A also becomes big, thereby produce the damage that causes by plastic deformation, but, form the scope that 50 degree～80 are spent by sieve hardometer D hardness of will shutting out, can prevent from thin plate compact 20A, to produce the damage that causes by plastic deformation.By like this, in appearance, can prevent to see the position that on end face 50Aa, produces plastic deformation, thereby can keep the outward appearance of keyboard 10A with flying colors.
And then in this example, the elasticity that has the degree of recovering with respect to pushing with the elastic resin hardenite is good.Under this situation,, also can form to make it restore to and push that the depression that causes disappears and state that cannot see this depression by this even push under the situation of thermoplastic resin membrane 21A at such hard things such as nail with the user.
In addition, in the keyboard 10A of this example, the gauge of printed layers 22A can be set at below the 15 μ m.Diminishing at the gauge of printed layers 22A is under the situation below the 15 μ m, because printed layers 22A is held between thermoplastic resin membrane 21A and the laminated film 23A, therefore, even the gauge at printed layers 22A is little, be under the situation below the 15 μ m, the damage that can prevent that also printed layers 22A takes place that damaged or printed layers 22A bursts apart etc.
In addition, in the keyboard 10A of this example,, therefore, become a plurality of key head 50A and pass through flange part 25A and connected state owing between a plurality of key head 50A, be provided with flange part 25A.Therefore, can provide a plurality of key head 50A by the keyboard 10A of integration.
In addition, when the keyboard 10A with this example is applicable in the electronic equipment of carried terminal 100 grades, can be suppressed at keyboard 10A and go up the situation that produces warpage, thereby can improve the quality of such electronic equipment such as carried terminal 100 grades by the minimizing of this warpage.
In addition, the words that the keyboard 10A of this example is compared with for example button of the employed rubber system of various remote controls, in keyboard 10A, because printed layers 22A is held between thermoplastic resin membrane 21A and the laminated film 23A, therefore, after forming printed layers 22A, there is the layered product LM of this printed layers 22A to be shaped clamping.Therefore, can form with recess 24A be representative various curved surface shaped, polyhedron shape etc., have various concavo-convex thin plate compact 20A and a printing that can have design to these different shapes.
In addition, the words that the keyboard 10A of this example is compared with the keyboard that forms by injection molding forming, form utilizing injection molding forming under the situation of keyboard, it is difficult generally the gauge of removing thin plate compact part in addition in the flange part (utilizing the gauge of the resin that penetrates pressure and fill) being formed the following thin-walled property of 0.8mm.But, adopt the manufacture method of above-mentioned keyboard 10A, also the gauge (gauge of elastic resin hardenite 30A) of removing the part beyond the thin plate compact 20A among the flange part 25A can be formed below the 0.8mm.Therefore, also can make the tabular keyboard that is flat pattern.
At this, in injection molding forming, flow into the resin of for example about 200 ℃ heating-up temperature, but also have a following situation, that is: produce because this temperature and producing on printed layers is damaged or because the problem of breakage etc. takes place for this temperature and thermoplastic resin membrane.But, in this example, printed layers 22A is held between thermoplastic resin membrane 21A and the laminated film 23A as described above, and the heating-up temperature in the time of will being injected into the thermosetting resin compression molding of recess 24A is 80 ℃～160 ℃, therefore, can prevent from printed layers 22A, to produce the situation of damage or thermoplastic resin membrane 21A generation breakage etc. with flying colors.
＜variation 〉
More than, the keyboard 10A that an example of the present utility model is related to, be illustrated as the carried terminal 100 of an example of electronic equipment and the manufacture method of keyboard 10A, still, in addition the utility model can also carry out various distortion.Below, this is narrated.
In above-mentioned example, the situation that keyboard 10A is applicable to carried terminal 100 as shown in Figure 8 is illustrated.But carried terminal is not limited to equipment shown in Figure 8, also goes for number such carried terminals such as portable telephone machine still less of key head.
In addition, in above-mentioned example, the shape of the end face 50Aa of key head 50A is smooth situation is illustrated.But the shape of the end face 50Aa of key head 50A is not limited to smooth shape, also can form shape (for example, curved surface shaped, spill, convex, waveform etc.) in addition.
In addition, in above-mentioned example, in the recess 24A of thin plate compact 20A, inject thermosetting resin, then by making thermosetting resin sclerosis formation elastic resin hardenite 30A.But, also elastic resin hardenite 30A can be formed consubstantiality not with thin plate compact 20A, then, will be coated with the recess 24A of the elastic resin hardenite 30A embedding thin plate compact 20A of bonding agent, thus thin plate compact 20A and elastic resin hardenite 30A is bonding.
