New description: [New technology field]. This creation involves keyboards and electronic devices. [Prior Art] A keyboard used in an electronic device such as a portable telephone has a keyboard disclosed in, for example, Patent Document 1. Patent Document 1 discloses a forming printed sheet in which a sublimation printed layer is sandwiched between a transparent thermoplastic resin layer and a thermoplastic resin layer 3 and laminated. Further, it is disclosed that a multi-Hungarian convex portion corresponding to the outer shape and arrangement of the key top is formed on the printing sheet for forming t, and the liquid portion is filled with a liquid ultraviolet curable resin, which is hardened by ultraviolet rays. , thereby forming a key member for the push button switch. Further, Patent Document 2 discloses that a light-shielding colored layer is formed on a laminate, and the light-shielding colored layer is removed to form a stamping symbol, and a light-transmissive coloring is provided on the stamping symbol. In the embossing, the layer is formed by the embossing, and the protective layer is attached to the inner side of the hollow portion. The second embodiment is disclosed in Japanese Laid-Open Patent Publication No. Special opening 2〇〇2_3〇7639 (summary of abstract description, paragraph 0〇58, etc.) > Patent Document 2: Japanese Laid-Open, Special Opening 2〇〇〇_113758 (summer description abstract, etc.) In the case of the above-mentioned Patent Document 1, the ultraviolet ray-type resin is filled with a liquid ultraviolet ray-type resin in the convex portion, and then cured by irradiation of ultraviolet rays into the 7-ray line. The hardening of the crucible, the shrinkage of the pupation (shrinkage), and the deformation of the M398151, for example, the back side of the key head is concave. Generally, since the ultraviolet curable resin is compared with other resins When the shrinkage at the time of hardening is large, such a problem (first problem) is apparently caused. In addition, when a liquid ultraviolet curable resin is used, a measure for reducing such shrinkage (shrinkage) is required. In the case where the step of making the keyboard is complicated, the process for manufacturing the keyboard is complicated, and it takes a lot of work (second problem). Further, as disclosed in Patent Document 2 In the case of the configuration, when an excessively soft material is used as the material of the protective layer substrate, the amount of deformation of the protective layer base is increased when the top surface of the key is pressed by an object such as a finger. There is a possibility that the amount of deformation on the pressed laminate film is also large, and plastic deformation occurs on the laminate film, and it is seen as damage (third problem). The present invention is formed based on the above situation. 'The object is to solve at least one of the first to third problems, to provide a small deformation due to shrinkage during manufacture, or to The process of manufacturing is simplified, or a keyboard and an electronic device capable of preventing plastic deformation when the surface is pressed. In order to solve the above problem, the first aspect of the keyboard of the present invention has a thin plate molded body provided with a concave portion and an elastic resin hardened. A thin plate molded body having a concave portion, wherein a printed layer is formed on one surface of a thermoplastic resin film, and a thermoplastic layer film is bonded in a state in which the printed layer is covered to form a plate-like laminate. 'The laminate is formed by heat molding to form an 'elastic resin cured body', and the thermosetting resin is formed by at least injecting a thermosetting resin into the concave portion, and after the injection, a thermosetting resin is formed to cure the thermosetting resin. The 吟4 M398151_solid resin is injected into the concave portion of the thin plate-shaped molded body, and then the elastic resin hardened body is formed by the hard enthalpy of the thermosetting resin. When the concave portion of the thin plate-shaped molded body is filled with the ultraviolet-curable resin, the shrinkage (shrinkage of the shrinkage hole) when the cured body is formed by the irradiation of the ultraviolet light is likely to occur, for example, the back side of the key head (keyboard) becomes However, the keyboard is manufactured by injecting a thermosetting resin into the concave portion of the thin plate-shaped molded body as described above, and it is possible to reduce shrinkage (shrinkage) of the thermosetting resin to cure the a word. Thus, it can be suppressed on the keyboard. In addition, when a cured body is formed using an ultraviolet curable resin, it is necessary to reduce the shrinkage (shrinkage) and to inject two or more stages of the ultraviolet curable resin in order to stabilize the size after ultraviolet irradiation. In the process, etc., the process is complicated. However, as described above, shrinkage (shrinkage) when the thermosetting resin is cured to form the elastic resin cured body can be reduced, and thus the cured body can be formed by using the ultraviolet curable resin. Compared with 'can reduce the man-hours when making the keyboard. Also' the keyboard of this creation In other respects, in the above creation, it is preferable that the D-hardness D hardness of the elastic resin hardened body is set to be in the range of 50 to 80 degrees. In the case of such a configuration, even a hard object such as a fingernail is used. When the elastic resin hardened body is pressed, it is possible to prevent damage due to plastic deformation in the thin plate molded body. That is, in the case where the elastic resin is more versatile, the wood is soft, and the amount of deformation is large, the thin plate In the deformation in the molded body, the damage caused by the plastic deformation is also large, but it is possible to prevent the occurrence of the 4-plate C-type spit by forming the hardness of the hardness meter D to a range of 5 to 8 degrees. Damage caused by plastic deformation. By thus being able to prevent the appearance of the portion M398151 which is plastically deformed on the top surface of the keyboard, it is possible to maintain the appearance of the keyboard excellently. In addition, other aspects of the keyboard of the present creation are In addition to the above-described respective creations, it is preferable to set the thickness of the printed layer to be 彳5 #m or less. In the case of such a configuration, the thickness of the printed layer is reduced to be small. 5 m or less 'but' because the printed layer is sandwiched between the thermoplastic resin film and the laminated ruthenium film, the printed layer can be prevented even when the thickness of the printed layer is small and 5 Å or less. In addition, the other aspects of the keyboard of the present invention are based on the above-mentioned respective creations, and further preferably have at least a plurality of key heads and flange portions, wherein a plurality of key heads The elastic resin hardened body is formed by entering the concave portion, and the flange portion is provided to have a smaller thickness dimension of the elastic resin hardened body than the key top, and is disposed between the plurality of key heads while being disposed around the key top In the case of such a configuration, the flange portion is provided between the plurality of key heads, so that the plurality of key heads are connected by the flange portion. Therefore, it is possible to provide a plurality of key heads to be integrated. The keyboard of the present invention is preferably any one of the creations of the above-mentioned keyboard. In the case of such a configuration, a thermosetting resin is injected into the concave portion of the thin plate-shaped molded body, and the elastic resin-cured body is formed by heat curing. In addition, when the concave portion of the thin plate-shaped molded body is filled with the ultraviolet-curable resin, it is easy to cause, for example, the back side of the key head (keyboard) to be concave, due to the curing shrinkage (shrinkage) at the time of ultraviolet irradiation. Deformation. However, by injecting a thermosetting resin into the concave portion of the cleansing-type body as described above, the keyboard can be manufactured to reduce the shrinkage (shrinkage) when the thermosetting resin is cured, and the M398151 can be prevented from being warped on the keyboard. Therefore, it is enough to improve the quality of the electronic device by the reduction of the warpage. With this creation, the deformation caused by shrinkage during manufacturing can be made small. In addition, the process at the time of manufacture can be simplified. In addition, it is possible to prevent plastic deformation from occurring when the surface is pressed. [Embodiment]

The thickness is formed to be 15 mm or less as described above, and at the same time, full color printing can be performed by superimposing, for example, cyan 'magenta or yellow. The other 'laminate film 23A' is a member for protecting the printed layer 22A. The pressure film 23A has a base layer and an adhesive layer. The material of the base layer is preferably a material made of a thermoplastic resin. Examples of the thermoplastic resin which is a material of the base layer include polypropylene resin, polyethylene resin, and polystyrene. • Vinyl resin, acrylic resin, polyethylene terephthalate resin (ρΕτ resin), polystyrene resin (ΡΡΕ resin), polyamide resin (ρΑ resin), polycarbonate resin (PC resin), Polyacetal resin, polybutylene phthalate resin (PBT resin), polystyrene ether resin (pps resin), polyether ether ketone resin (PEEK resin), liquid Any one of a polymer (LCp), a fluororesin, a polydecylester resin, an elastic material, or the like, or a mixture of these. As the base layer of the laminate film 23A, the same raw material as the above-mentioned thermoplastic resin film 21 A can be used. In addition, different raw materials may be used. In addition, the adhesive layer is a material which is softened and melted at a lower temperature than the base layer, and may be exemplified by low-density polyethylene resin, ionomer, and baking. Ethylene-Vinyl Acetate Copolymer, poly-resin resin, polyurethane resin, acrylic resin, epoxy resin, etc. as a raw material bonding material. Further, in the present embodiment, the temperature at which the adhesive layer is sinus-melted is lower than the heat-resistant temperature of the printed layer 22Α. The laminate 4 film 23 is laminated to have a plate shape before molding, and the thickness of the base layer is preferably 38 W.25Q" (7). When the thickness of the base M398151 layer is less than 38 #m, the ruthenium film of the thermoplastic resin may be damaged or the like. Therefore, the base layer is preferably formed to have a thickness of 38/zm or more. Further, in the case where the thickness of the base layer is larger than 25 〇em, the flexibility at the time of forming the thin plate-shaped molded body 20A is deteriorated, and the thickness of the entire laminated film 23A is also increased. Therefore, the base layer is preferably formed to have a thickness of 250 m or less. Further, the thickness of the adhesive layer is preferably in the range of 1 'um to 25 #m. In the case where the thickness of the adhesive layer is more than 2 5 /z m, the flexibility of the laminate film 2 3 A is deteriorated, or the thickness of the entire laminate film 23A becomes large. Therefore, the dry layer is formed by: the following thickness dimension is preferable, and when the thickness dimension of the contact layer is smaller, the stability of the adhesion layer coating cannot be obtained. There is a case where a part of the unbonded portion or the like is not obtained, and the uniformity of the bonding or the inability to obtain a sufficient adhesive force is increased. Therefore, it is preferable that the adhesive layer is formed to have the above thickness dimension. In addition, in the present embodiment, the elastic resin cured body 3A is a portion obtained by curing the #-body resin having a 疋 疋 &. _ is a material of the elastomer resin, and examples thereof include polyacetal rubber, Shixia rubber, acrylic rubber, kiln nitrile rubber, and isoprene rubber. The elastic resin is preferably 30A', and it is preferable that the elastic property is such that it is restored to the extent of the pressing of the hard object such as the nail of the user. <Method of Manufacturing the Disk 10A> A method of manufacturing the keyboard 1A having the above configuration will be described. FIG. 2 is a flowchart for explaining an outline of a method of manufacturing the keyboard. 3 and 4 are views for explaining a method of manufacturing the keyboard 10A. I0 M398151 • First, a thermoplastic resin film 21A is prepared (step S01, see Fig. 3(A)). When a wound roll ("〇丨丨" body is used as the thermoplastic resin film 2彳a, for example, the roll body is fixed to a predetermined portion of a printing apparatus for performing printing. Then, it is formed to be thermoplastic. The resin thin film 2 1A is drawn out from the roll body every predetermined length. Next, printing is performed on one surface of the thermoplastic resin film 21A to form the printed layer 22A (step S02, reference item 3 (B)). Specifically, The printing apparatus is operated to start the extraction of the thermoplastic resin film 21A from the roll body, and only the thermoplastic resin film 21A is taken out to a length required for performing one printing operation at the printing position of the printing apparatus. The image data for printing is converted into information for operating the print head of the printing device (data for driving the print head), and the print head is operated based on the data for driving the print head to form a desired print. The printed layer 22A of the image is formed in the form of the printing layer 22A, which can be formed only by the actual e-printing, and can also be heavy. The printing is carried out a plurality of times. In addition, before the formation of the printing layer 22A or after the formation of the printing layer 22A, the laminated film 23A is prepared in advance. For example, the wound roll is used as the laminated film 23A. In the case of a body, the roll body is fixed to a predetermined portion of a laminating apparatus for lamination (lamination processing). Further, the thermoplastic resin sheet 21A after the printed layer 22A is formed is also fixed to the laminating apparatus. In this state, lamination (lamination processing) is performed (step s〇3, see Fig. 3(C)). That is, if the laminating apparatus is operated in the state after the above-described fixing is completed, The thermoplastic resin film 21A on which the M398151 layer 22A is formed is drawn at the portion where the lamination is performed. On the other hand, the laminate film 23A is also broken by the operation of the laminating apparatus. At this time, the laminated film 23A and the thermoplastic resin film 21A are aligned with each other. Further, the laminated laminated sheet 23A is overlapped in a state in which the dead potential is in contact with the printed layer 22A. weight In the lamination, the roller which is heated to a predetermined temperature by a heater or the like in advance is pressed from the base layer of the laminate film 23A. By the pressing of such a heated roller, lamination is performed. The adhesive layer of the film 23A is softened and swelled. However, when the film is cooled, the adhesive layer is cured. Thus, the printed layer 22A and the base layer are bonded together by the adhesive layer, and the formation is performed. Laminated laminate (laminated body) LM. In addition, when an acrylic resin sheet with a hot-melt adhesive is used as the laminate film 23A, the temperature of the drum at the time of lamination is a suitable temperature. It is 73 C, however, as long as the temperature of the drum is 6 〇. The range of c~160a C can be any temperature. In addition, 'the speed of the rushing speed of the wave when laminating' is 2.0 m/min, but it can be any as long as the feed speed of the drum is in the range of 0.5 m/min to 6.0 m/mjn. Feed rate. Further, the 'lamination' may be carried out using a heated metal plate without using the above-described heated roller. Next, thin sheet forming is performed (refer to Fig. 3(D) in step S04'). In the sheet forming process, the laminated body LM after the lamination is fixed to a predetermined position of one of the press-molded dies. On one of the molds of the press molding machine and the other mold, an uneven shape that is symmetrical with the convex portion of the key top and the concave portion 24A is formed. After the laminate LM is fixed to one of the molds of the press molding machine, while maintaining a predetermined heating temperature, the other mold of the predetermined 12 M398151 press molding machine is used to emulate one mold and another deformation. Thereby, a mold having a concave pressure is pressed against one of the molds. Thus, the convex sheet-shaped compact 20 进行 is formed in the form of the uneven shape of the mold of the plate-like laminate L 一方 . Next, in the concave portion 24 corresponding to the key top in the thin plate molded body 20, an elastomer resin is injected using an injection device (step s〇5, see Fig. 4(A)). Further, when the keyboard 彳〇A as shown in the first figure is formed, the elastomer resin is injected by covering the flange portion 25A other than the concave portion 24A.

In addition, when the top surface 50Aa of the key top 5A of the keyboard 1A is pressed with a hard object such as a nail to form a depression, the depression is restored to the original shape. However, the keyboard 10B of the comparative example is pressed with a hard object such as a nail. When the top surface of the key head 5〇B was formed to form a depression, it was found that the depression was not recovered. As a result, in comparison with the keyboard 10B of the comparative example, the keyboard 10A according to the present embodiment is excellent in the restoring force against the pressing force from the outside of the keyboard 10B, and can maintain the top of the key head 5A. Surface 5〇Aa I6 M398151 Smoothness. <Different point 2> As shown in Fig. 1, the keyboard 10A does not have a thin plate for fixing the back surface. On the other hand, as shown in Fig. 5, the keyboard 1 〇 B has a film 4 〇 B for fixing the back surface. <Different point 3> The keyboard 1 Ο A ' in the present embodiment is formed by curing a thermosetting resin such as an elastomer resin to form the elastic cured body 30A. On the other hand, in the keyboard 10 B of the comparative example, the UV resin cured body 30B was formed by the curing B of the ultraviolet curable resin. Here, when the case where the thermosetting resin such as the uncured elastomer resin is cured is compared with the case where the uncured ultraviolet curable resin is cured, the uncured ultraviolet curing is performed as compared with the case where the uncured thermosetting resin is cured. The shrinkage in the case where the resin is hardened becomes large. Therefore, the keyboard 10A in the present embodiment can be formed with higher precision than the keyboard 1 AB of the comparative example. Further, the shrinkage ratio at which the UV resin cured body 30B is formed by using the ultraviolet curable resin is 5 to 1 5%. On the other hand, the shrinkage ratio at the time of forming the elastic resin body 30A using urethane rubber is 1 to 4%, and the shrinkage ratio at the time of molding the elastic resin body 30A using ruthenium rubber is 1 to 4%. Further, as described above, in the keyboard 1B of the comparative example, the first stage of the ultraviolet curable resin is injected, and then the first stage of curing by ultraviolet irradiation is performed, and then the second stage of ultraviolet curing is performed. After the injection of the resin, the back surface fixing 4貘40B is pressed up by a predetermined pressure, and the second stage of the ultraviolet ray irradiation is performed. In contrast, in the keyboard 彳〇A of the present embodiment, only the keyboard 彳〇A can be passed. Injecting «98151' of the secondary uncured elastomer resin and forming it by press molding thereafter. Therefore, it is possible to reduce the number of man-hours in the manufacture of the keyboard 10A. (4) Regarding the embodiment, The evaluation of the operation at the time of the pressing of the basic keyboard is described. (Configuration of the first embodiment) (Production of the sample) First, "Mitsubishi Rayon Co., Ltd." as a thermoplastic resin film The acrylic resin molding material N47 (ACRYPET, trade name) having a thickness of 75 # m is digitally printed using a printing device. In the laminating apparatus, a thermosensitive adhesive-coated acrylic resin sheet having a thickness of 75 μm as a laminate film and a digitally printed thermoplastic resin film as described above are pressed by a cylinder heated to 73 C. In addition, the feed speed of the drum at this time was 2.0 m/min. By this, the lamination between the thermoplastic resin film and the laminate film was carried out 'to thereby form a laminate. Next, the laminate was laminated. The body is subjected to press forming. At the time of the press forming, the laminate is heated at 16 CTC for 3.5 seconds in a molding die of a compression molding machine. Next, the forming die is operated to form a molding die. One of the molds and the other of the molds were placed on the laminate for 5.0 seconds, and the plate-like laminate was deformed in the same manner as the concave and convex shape of the other mold by the chemical conversion, thereby forming a thin-plate shaped body having a concavo-convex shape. Next, a polydecyl ester resin as a thermosetting resin is injected into a concave portion corresponding to the key top in the thin-plate-type molded body. The hardness type D durometer was 60. Then, the polyurethane resin was cured by heating and compression molding at 100 ° C for 1 minute and 30 seconds to obtain a bond of 2.0 mm (including a film). The rubber hardness of the obtained bond head, that is, the cured elastic resin hardened body, measured by a rubber hardness meter type D (manufactured by ASKER Co., Ltd.) was measured and recorded, and the measured value after 15 seconds was recorded, and the result was The Duro hardness meter D hardness was changed to 57. In addition, a slight error was included in the D hardness of the Durau hardness meter 57 (the same applies to the following hardness values). (Evaluation of the depression of the first embodiment) When the depression was formed by pressing the keyboard 10A having the elastic resin hardened body having such hardness with a hard object such as a nail, it was found that the original state was restored to the original smooth state and the depression disappeared. That is to say, the nail is pressed hard, and the state of damage and depression caused by the pressing is not seen shortly thereafter. (Construction of the second embodiment) The second embodiment is the same as the first embodiment except that the polyurethane resin which is a thermosetting resin in the concave portion to be injected into the thin plate molded body is different. The hardness after hardening of the polyurethane resin used in Example 2 was measured. As a result, the Durau hardness meter D hardness was 64. (Compensation of the depression of the second embodiment) When the depression is formed by pressing the keyboard 10A having the elastic resin-hardened body having such hardness with a hard object such as a finger, it is found that the original smoothness is restored in the same manner as in the first embodiment. The state disappears and the depression disappears. That is to say, the erect fingernail is pressed hard, and the state of the damage and depression caused by the pressing is not seen shortly thereafter. (Configuration of the third embodiment) The M398151 is the same as the first embodiment except that the polyurethane resin which is a thermosetting resin in the concave portion to be injected into the thin plate molded body is different. The hardness after hardening of the polyurethane resin used in Example 3 was measured. As a result, the Durau hardness meter D hardness was 50. (Evaluation of the depression of the third embodiment) When a depression is formed by pressing the keyboard 10A having the elastic resin-hardened body having such hardness with a hard object such as a nail, it is found that the original smooth state is restored in the same manner as in the first embodiment. The depression disappeared. That is to say, the finger is pressed hardly, and the state of the damage and the depression caused by the pressing is not seen shortly thereafter. (Configuration of the fourth embodiment) The same as the first embodiment except that the polyurethane resin which is a thermosetting resin in the concave portion to be injected into the thin-plate shaped body is different. The hardness after hardening of the polyurethane resin used in Example 4 was measured. As a result, the Durau hardness meter D hardness was 80. (Compensation of the depression of the fourth embodiment) When a depression is formed by pressing the keyboard 10A having an elastic resin hardened body having such hardness with a hard object such as a finger, it is found that there is still a depression and no recovery even after a lapse of time ( Seen as a depression). When the cause of the depression was confirmed, it was found that the elastic resin hardened body was damaged, and a recess remained on the surface of the key top. (Configuration of Comparative Example 1) In Comparative Example 1, the same as in Example 1 except that the polyurethane resin which is a thermosetting resin to be injected into the concave portion of the thin plate molded body was different. The result of measuring the hardness after hardening of the polyurethane resin used in Comparative Example 1 was 20 M398151, and the Durau hardness meter D hardness was 33. (Evaluation of the depression of Comparative Example 1) When the depression was formed by pressing the keyboard 10B having the elastic resin hardened body having such hardness with a hard object such as a nail, it was found that the damage was not recovered even after a lapse of time. When the cause of the damage was confirmed, it was found that the elastic deformation of the elastic resin cured body was increased in Comparative Example 1, and plastic deformation occurred in the thin plate. (W. Composition of Comparative Example 2) In Comparative Example 2, the same as Example 1 except that the thermosetting resin injected into the concave portion of the sheet-shaped molded body was different. In Comparative Example 2, ruthenium rubber was used as the thermosetting resin. As a result of measuring the hardness of the hardened rubber (elastic resin hardened body) of the enamel rubber, the Durau hardness meter D hardness was 2 Torr. (Evaluation of the depression of Comparative Example 2) When the depression was formed by pressing the keyboard 10B of the elastic resin-hardened body having such hardness with a hard object such as nails, it was found that damage occurred even after a lapse of time and was not recovered. When the cause of the damage was confirmed, it was found that the elastic deformation of the elastic resin cured body was larger in Comparative Example 2, and plastic deformation occurred in the thin plate molded body. (The extinction of the evaluation of the dent) The results of k or more were found to be in the case of Examples 1 to 4, and there was no damage due to plastic deformation of the thin-plate shaped body. From this, it can be said that if the Duro hardness meter D hardness of the elastic resin hardened body is in the range of 50 to 80 degrees, * because there is no damage caused by plastic deformation of the thin plate shaped body, better results can be obtained. . Further, it has been found that in the case of the examples 〜3, the state in which the recess is not visible on the surface of the keyboard is obtained. Therefore, if the hardness of the Douro hardness meter of the hardened M398151 resin is in the range of 5G to 64 degrees, the tongue is better because no depression is visible on the surface of the keyboard. (About click rate) Receiver's on the above embodiment! ～4 and comparative examples, and 2, the click rate was measured. Here, the so-called click rate (%) refers to two (8) which is determined by the following formula: In addition, 'c indicates the click rate (%), p indicates the maximum load (unit: gram), and B indicates the bottom load (unit: gram). In addition, the maximum load indicates the maximum load before the metal dome is bucked, and the Lu load table does not maintain the minimum load of the buckling state after the metal dome is buck.

In the stick terminal 1A as shown in Fig. 8, such a button arrangement is also employed when 30 or more key heads 50A are arranged. Further, the key array portion 510' is not only an arrangement of a straight grid shape (褀 格 状) which is not the same as the 千 图 N N N , , , , , , , , , , , , , , , , , N N N N N N N N N N The staggered arrangement 3 In order to realize the above-described button arrangement unit 500, the keyboard 1 of the present embodiment as shown in Fig. 9 is used. However, the keyboard 10 Α may be used to realize the cursor key unit 400, and the keyboard 1 使用 may be used to realize both the key arrangement unit 500 and the cursor key unit 400. Further, the installation portion of the setting keyboard > 10 0 in the portable terminal 100 is located inside the casing 200. The set portion is in direct contact or indirect contact with the keyboard 1A. As shown in Fig. 9, a plunger 60 is provided in a portion of the keyboard 1 which is opposed to the substrate unit 6A. A plunger 60 must be provided on each of the key heads 50''. However, it is also possible to adopt a configuration in which a plurality of plugs 60 are provided on one key head 50A. Further, the plunger 60A may form part of the elastic resin cured body 30, or may be formed by bonding a member different from the elastic resin hard body 30A by adhesion or the like to form the plunger 6〇a. Further, the plunger 60A is provided such that when the respective key heads 5A are pressed, the corresponding plunger 60A presses the metal dome 630 which will be described later. As shown in FIG. 9, the substrate unit 600 is provided in a state facing the keyboard 1A in the inside of the casing 200. The substrate unit 600 has a substrate 61 0, fixed contacts 620a ' 620b, and a metal dome 630. The _8151 substrate 610 is provided with fixed contacts 620a, 620b and a metal dome 630 @ circuit, which are capable of generating a corresponding pressing of the respective key heads 5A. number. Further, the 'fixed contacts 62Qa, 6 are part of the conductive portion formed on the substrate (4). Further, the metal dome 63 has a shape in which the outer rim is inverted, and the edge portion of the metal dome 63 相 is in contact with at least a portion of the fixed contact 620a on the substrate 61 。. The metal dome 63 is set to be distorted (planarly curved). In this case, if the user presses the production head 5〇A and applies a predetermined pressing force to the metal dome 630, a part of the metal dome 630 is deformed from the convex state to the Z1 direction in FIG. Concave state. At this time, the portion of the metal dome 63 is in contact with the fixed contact 620b, and thus the fixed contact 62a and the fixed contact 620b are electrically connected to each other by the metal dome 630. Further, when the depression of the key head 50A is released, the buckling state disappears due to the elasticity of the metal elastic piece 630, and the original state is restored. By this, the metal dome 630 and the fixed contact 620b become non-contact, and thus are in a non-electrical state. <Effects> When the keyboard 1A' of the above-described configuration is used as the portable terminal 100 of the electronic device and the manufacturing method of the keyboard 1A, the thermosetting resin is injected into the concave portion 24A of the thin plate molded body 20A, and then passed through The thermosetting resin is cured to form an elastic resin cured body 30A. When the ultraviolet curing resin is filled in the no portion 24A of the thin-plate pressure-reformed body 20A, the shrinkage (shrinkage) when the UV resin cured body 30B is formed by irradiation of ultraviolet rays is likely to occur, for example, the key head 50B. The back side of the keyboard 10B is deformed in a concave shape. However, by inserting the thermosetting resin into the concave portion 24A as described above, the keyboard 10A can be made to reduce shrinkage (shrinkage) when the thermosetting resin is cured. In this way, it is possible to prevent the occurrence of the assembly of the UV resin cured body 30B by using the ultraviolet curable resin. In the case of forming the UV resin cured body 30B using the ultraviolet curable resin, it is necessary to reduce the shrinkage (shrinkage) and to use it for ultraviolet irradiation. After the process of stabilizing the dimensions, etc., the process is complicated. However, it is possible to reduce the number of man-hours in the production of the keyboard 10A by using the ultraviolet curable resin to form the UV resin cured body 30B as compared with the case where the thermosetting resin is cured to be cured as described above. In the keyboard 10A of the present embodiment, when the durometer D hardness of the elastic resin cured body 30A is in the range of 50 to 80 degrees, the elastic resin is hardened even by pressing a hard object such as a finger lick. When the body 3〇A forms a depression, it is possible to prevent damage caused by plastic deformation in the thin plate molded body 2qa. In other words, when the elastic resin hardened body A is too soft and the amount of deformation is large, the amount of deformation in the thin plate molded body 2A is also increased, thereby causing damage due to plastic deformation, but by using Duro The durometer D hardness is formed in a range of 50 to 8 Torr to prevent the occurrence of damage due to plastic deformation on the thin plate molded body 20A. Thus, the 'appearance' can prevent the plasticity from being observed on the top surface 5AAa. The deformed portion 'is thus excellent in maintaining the appearance of the keyboard 1A. • In the actual % shape '15, it is preferable that the elastic resin hardening If has a degree of recovery with respect to pressing. In this case, even when the thermoplastic resin film 21A is pressed by a hard object such as the user's finger f or the like, it can be formed so as to return to the depression of the button (4) and disappear. The state of the depression. Further, in the keyboard 1A of the present embodiment, the thickness of the printed layer 22a can be set to 15/z or less. In the case where the thickness of the printed layer 22A is less than 15 vm, the printed layer 22A is sandwiched between the thermoplastic resin film 21A and the laminate film 23A. Therefore, even if the thickness of the printed layer 22A is small, When it is 15 #m or less, it is also possible to prevent damage of the printed layer 22A or damage such as cracking of the printed layer 22A. In the keyboard 10A of the present embodiment, the flange portion 25A is provided between the plurality of key heads _ 5GA, so that the plurality of key heads 5QA are connected by the flange portion 25A. Therefore, it is possible to provide a keyboard 1 〇A in which a plurality of key heads are integrated. Further, when the keyboard 1A of the present embodiment is applied to an electronic device such as the portable terminal 1A, it is possible to suppress the occurrence of warpage on the keyboard 1A, thereby improving the warpage by the reduction of the warpage. The quality of the electronic device such as the terminal 1 is carried.
另外，將本實施形態的鍵盤10A與例如各種遙控裝置 所使用的橡膠制的按㈣目比較的話，在鍵盤彳QA中，由於 印刷層22A被夾持於熱塑性樹脂薄膜21八與層壓薄膜23a 之間，因此，在形成印㈣22A之後，將失持有該印刷磨 22A的層壓體ι_Μ成形。因此，能夠形成以凹部24八為代 表的各種曲面形、多^Q ^ ^夕囟組形專的、具有各種凹凸的薄板壓 型體20A，並能夠餅此& & 。， n幻對&些各種形狀進行具有設計性的印刷。 另外，將本實施形態的鍵盤10A與通過注射模塑成形 而形成的鍵盤相比較的$，Λ χ 1 ^ 在利用注射模塑成形而形成鍵 盤的情況下，一般蔣Λ 4矣μ七& μ 1 _ 又將a束„卩中的除去溥板壓型體以外的部 M398151 • 分的厚度尺寸（利用射出壓力而填充的樹脂的厚度尺寸） 形成為0.8mm以下的薄壁化是困難的。但| 休用上述鍵 盤1 0A的製造方法的話，也能夠將凸緣邹25A中的除去等 板壓型體20A以外的部分的厚度尺寸（彈性樹脂硬化體3〇a 的尽度尺寸）形成為Ο.δηηπη以下。因此，也能夠製造呈烏 平形狀的板狀的鍵盤。 在此’在注射模塑成形中，流入例如約2〇〇。C的加熱 溫度的樹脂’但是也存在如下的情況，即：產生由於該溫 • 度而在印刷層上產生損壞、或由於該溫度而熱塑性樹脂薄 骐發生破損等的問題。但是，在本實施形態中，如上述那 樣印刷層22Α被夾持於熱塑性樹脂薄膜21Α與層壓薄睽 23Α之間，且將被注入凹部24Α的熱固性樹脂壓縮成形時 的加熱溫度為8CTC ~16(TC，因此，能夠出色地防止在印 刷層22A上產生損壞、或熱塑性樹脂薄骐2彳a發生破損等 的情況。 〈變形例> 以上，對本創作的一實施形態涉及的鍵盤彳〇 A、作為電 子叹備的例的搞帶終端1 〇〇以及鍵盤1 0A的製造方法進 仃了說明’但是，本創作除此之外還可以進行各種變形。 以下，對此進行敍述。 在上述實施形態中，對將鍵盤1 0A適用於圖8所示那 樣的攜咿終# 1 〇〇的情況進行了說明。但是，$帶終端通 不限於圖8所不的設備，也可以適用於鍵頭的個數更少的 指;帶式電話機裝置等那樣的攜帶終端。 另卜在上述實施形態中，對鍵頭50A的頂面50Aa 30 _8151 的形狀呈平坦的情況進行了說明。但是，鍵頭50A的頂面 5QAa的形狀並不限於平坦的形狀，也可以形成為除此之外 的形狀（例如，曲面形 '凹形、凸形 '波形等）。Further, when the keyboard 10A of the present embodiment is compared with, for example, the rubber used in various remote control devices, in the keyboard 彳QA, the printed layer 22A is sandwiched between the thermoplastic resin film 21 and the laminated film 23a. Between, therefore, after the printing (four) 22A is formed, the laminate ι_Μ holding the printing mill 22A is formed. Therefore, it is possible to form a plurality of thin-plate shaped bodies 20A having various irregularities and various types of irregularities, which are represented by the concave portions 24, and can be used for &&& , n illusion & some of these shapes for design printing. Further, in the case where the keyboard 10A of the present embodiment is compared with a keyboard formed by injection molding, Λ χ 1 ^ is formed by injection molding to form a keyboard, generally Λ Λ 4矣μ7 & μ 1 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ However, when the manufacturing method of the above-described keyboard 10A is used, the thickness dimension (the full size of the elastic resin cured body 3〇a) of the portion other than the plate-shaped molded body 20A in the flange 25A can be formed. In the meantime, it is also possible to produce a plate-shaped keyboard in the shape of a flat. Here, in the injection molding, a resin of a heating temperature of, for example, about 2 〇〇 C is flowed in. That is, there is a problem that damage occurs in the printed layer due to the temperature, or the thermoplastic resin is damaged due to the temperature. However, in the present embodiment, the printed layer 22 is clamped as described above. The heating temperature between the thermoplastic resin film 21Α and the laminated thin film 23Α and the thermosetting resin injected into the concave portion 24Α is 8 CTC to 16 (TC), so that damage to the printed layer 22A can be excellently prevented. In the case where the thermoplastic resin sheet 2彳a is damaged, etc. <Modification> As described above, the keyboard 彳〇A according to an embodiment of the present invention, the splicing terminal 1 例 as an example of an electronic sigh, and the keyboard 1 The manufacturing method of 0A has been described. However, the present invention can be variously modified in addition to the above. In the above embodiment, the keyboard 10A is applied to the carrying as shown in FIG. The case of 咿 terminal # 1 进行 has been described. However, the band terminal is not limited to the device shown in Fig. 8, and may be applied to a finger having a smaller number of key heads; a portable terminal such as a band phone device or the like. Further, in the above embodiment, the case where the top surface 50Aa 30_8151 of the key top 50A has a flat shape has been described.
