At the same time, the button part 19 will return from the pressed position (refer to the pressed position in FIG. 22 to the non-pressed position (refer to the non-pressed position II in FIG. 22). Here, the aforementioned so-called film key 71 is For example, it is a thin disc-shaped metal contact part with an outer diameter of 105 mm, a bending height of 0.25 mm, and a thickness of 60 mm. It also has the key touch performance and the button performance. The key sheet member related to the first embodiment of the present invention 丨The decorative plate 2 which is composed of a translucent base plate with a visible light transmittance of 80% to 93% and a turbidity of 5% to 50%. At least the metal film layer 7 has been laminated on the moon surface side. Most of the transparent resin members 11 are integrated (see FIG. I). The decorative plate 2 is provided on the back side of the translucent base plate 3 described in the visible light transmittance 80% to 93% and the turbidity 5/6 to 50 /. Through the above-mentioned fixing layer 6, at least the above-mentioned metal thin film layer 7 has been laminated (refer to FIGS. 2 to 4) 20 In detail, for example, the decorative plate 2 of the key plate member 1 related to the embodiment described above is sequentially passed from the outside to the inside by the translucent base plate 3, the fixing layer 6, and the metal film. Layer 7, a translucent colored layer 8, a light-shielding colored layer 9, and an adhesive layer 10. The translucent substrate 3 is composed of the transparent substrate 4 and the light diffusing layer 5. 12 ^ 00301729 玖2. Description of the invention In the key sheet member 1 related to the first embodiment of the present invention, the important translucent substrate described above is only the visible light transmittance of 80% to 93% and the turbidity of 5% to 50%. For example, a light diffusing material is mixed into the resin of the aforementioned substrate 3 and heated and stirred to mix and mold as the above structure. If the visible light transmittance is within the range of 80% to 93%, a glossy pattern or Excellent metallic luster, such as wool pattern. If the visible light transmittance is less than 80%, the metallic luster produced by the aforementioned metal thin film layer 7 cannot be reproduced. If the visible light transmittance exceeds 93%, the aforementioned substrate plate 3 is touched by something The tiny traces produced when touched will become visible It is easy to see. Moreover, if the haze is within the range of 5% to 10 50%, excellent metallic luster such as a gloss pattern or a hairline pattern can be developed. If the haze is less than 5%, it is generated by the aforementioned metal thin film layer 7 The metallic luster cannot be reproduced. If the turbidity exceeds 50%, the backlight time will be too scattered and the whole will become dark. The resin of the substrate 3 can be polyethylene terephthalate resin 15, Single layer of any one of polycarbonate resin, acrylic resin, olefin resin, urethane resin, polycarbonate polybutylene terephthalate mixture resin or two layers laminated Above. However, when there are multiple contact bonds, it is used from polyamine, polyimide, tobacco, amino acid, polycarbonate polybutylene terephthalate mixture resin, and polycarbonate. The resin film selected from g purpose polyethylene 20 terephthalate mixture resin is preferable. As the light diffusing material contained in the resin of the substrate 3, fine particles such as titanium oxide, aluminum hydroxide, barium sulfate, polystyrene resin, styrene vinyl methyl methacrylate polymer resin, or stone oxide can be used. , Ming and other ground pigments or resin beads. The light diffusing material preferably contains 1 to 30% by weight. 13 发明 Description of the invention If the light diffusing material of the resin contained in the aforementioned base plate 3 is in a range of 1 to 30% by weight, excellent metallic luster such as a gloss pattern or a wrinkle pattern can be exhibited. If the light diffusing material is less than 1% by weight, the glossiness and the like may be insufficient and the metallic glossiness may be too strong. Therefore, the visibility may be impaired when a pattern such as a letter is displayed. If the right light diffusing material exceeds 30% by weight, there is a possibility that the metallic luster generated by the aforementioned metal thin film layer 7 will not be reproduced. When forming the substrate 3, the translucent substrate 3 can be formed by forming a desired metal structure between the metal tubes having a small uneven shape and providing a small concave and convex portion on the surface of the plate. Here, the so-called desired small 10-concave-convex part can obtain the same degree of concavity and convexity as when the light-diffusing material is contained, and specifically, the surface roughness Ra is 5 // 111 to 10 "m of concavity and convexity. The translucent substrate 3 is not limited to a single layer as shown in FIG. 2, and a light-diffusing material containing 1 to 30% by weight may be laminated on the surface side of the transparent substrate 4. The light diffusing layer 5 is used as the translucent base plate 3 (see FIG. 3). The transparent base plate 4 may be the same resin plate as the resin plate of the translucent base plate 3. The light diffusing layer 5 As the resin, a radiation-hardenable resin, a thermoplastic resin, a thermosetting resin, etc. can be used. The light-diffusing material contained in the resin of the light-diffusing layer 5 can be the same as the light-diffusing material used in the aforementioned 20 translucent substrate 3 The material is the same. The thickness of the translucent substrate 3 in Figures 2 and 3 should be 15 mm to 2 m. If the thickness of the translucent substrate 3 is less than… m, then the film of the translucent substrate 3 is formed. Steps will be difficult and processing in each step It is also not good. Also, it is impossible to trace to the extension of the translucent base plate 3 when it is ready to be formed. 200301729 5 10 15 发明, invention description exhibition, and the risk of fracture at the place where it becomes a thin wall is high. If the thickness of the shirt body plate 3 exceeds 25 °, it will take a long time to heat the decorative plate 2 to the optimal state for pre-forming, and the production efficiency will deteriorate, and even if the role of the surface protection layer of the key _1 is considered The thickness above this thickness is also not required and involves an increase in cost. However, when there are multiple contact keys shown in FIG. 12, based on the above reasons, the thickness of the translucent substrate plate 3 of FIGS. 2 and 3 It is preferable to set it to 5 to 25.0 em 'and the elongation of the decorative plate 2 in which the key button portion 19 is formed is preferably in a range of 2 嶋 to ％%. If the translucent substrate plate 3 is prepared in advance The elongation rate is too high and exceeds 30% at the time, and the contact part of the central key and the frame-shaped key from the fresh method to the stretch will be thin, and it will break after long-term use, and during use (when pressed, If you press the D key in the position shown in Figure U, the original position cannot be restored.

This is because if the visible light transmittance of the aforementioned metal thin film layer 7 is less than 1%, the light transmittance during backlighting will be hindered, and if the visible light transmittance of the metal thin film layer 7 exceeds 30%, the metallic luster will be impaired. The reason. The visible light transmittance 10 of the so-called metal thin film layer 7 in the present invention refers to the visible light transmittance of the individual metal thin film layer 7 except when specifically noted. From the aspect of manufacturing steps, the metal thin film layer 7 is preferably formed with a film thickness of 10 nm to 40 nm. This is because when the film thickness of the metal thin film layer 7 is less than 1 Gnm _, the film thickness processing in the steaming step becomes difficult, and when the film thickness of the metal thin film layer 7 exceeds 40 nm, 15 Risk of corrosion. The metal thin film layer 7 is entirely or partially formed. By forming the metal thin film layer 7 partially, it is possible to construct a structure in which patterns such as characters and symbols can be displayed when a light source is arranged on the back surface side of the key plate member i. The method for partially forming the metal thin film layer 7 includes a lithography method.

After forming the metal layer 7 and the light-shielding layer on the entire surface of the substrate 3, the metal thin film layer 7 and the light-shielding layer are removed into a desired pattern shape by laser light. In addition, in order to provide softness to the metal thin film layer 7 for the purpose of softening and explaining the invention, a light-shielding colored layer 9 may be formed. This light-shielding colored layer 9 can also be used as a masking layer when partially forming the metal thin film layer 7 (see the first drawing). When it is necessary to strengthen the tight bonding between the base plate 3 and the interlayer 5 of the metal thin film layer 7, a fixing layer 6 may be provided (see Fig. 4). As the fixing layer 6, a two-liquid curable urethane resin, a thermosetting resin such as a melamine resin or an epoxy resin, and a thermoplastic resin such as a vinyl chloride polymer resin can be used. The method for forming the fixed layer 6 includes a coating method such as a gravure coating method, a roll coating method, and a dot coating method, a printing method such as a gravure printing method, and a screen printing method. In addition, the fixed layer 6 is colored, so that it can be colored with metallic luster. In addition, a pattern layer (for example, one of the metal thin film layer 7 or the light-shielding colored layer 6 or the adhesive layer 10) may be provided to display characters, symbols, and patterns. The material of the pattern layer is polyethylene resin, polyamide resin, polyester resin, acrylic resin, polyurethane resin, polyethylene 15 acid resin, polyester amino resin, As the binder, resins such as a cellulose ester resin and an alkyd resin may be used, and a coloring ink containing a pigment or a dye of an appropriate color as a colorant may be used. The pattern layer may be formed by a common printing method such as a lithographic method, a gravure printing method, or a screen printing method. The pattern layer may be partially formed in accordance with a pattern to be expressed. 20 Also, when the metal thin film layer 7 is partially formed, a translucent colored layer 8 having a visible light transmittance of 50% to 95% formed at another portion may be provided (see FIGS. 2 to 4). By forming the light-transmitting colored layer 8 on a portion where the metal thin-film layer 7 is not formed, it is possible to construct a pattern such as a character or a symbol when a light source is arranged on the back side of the key sheet member 1. The resin for forming the light-transmitting color layer 8 will be described with reference to 24 玖. The thermoplastic resin or the thermosetting resin may be appropriately selected and used. The “adhesive layer 10” can also be formed according to the need (refer to FIG. *). The adhesive layer 10 can be colored regardless of whether it is transparent or translucent. Five colors are used as the light-shielding colored layer 9 or the light-transmitting colored layer 8. The adhesive layer 1G is used to adhere the foregoing layers to the transparent resin member ^. The adhesive layer 10 is made of a heat-sensitive or pressure-sensitive resin suitable for the material of the transparent resin member 11 as appropriate. For example, when the material of the transparent resin member U is a polycarbonate resin, it is preferable to use an acrylic resin, a polystyrene resin, a polyamide resin, and the like, which have an affinity with these tree moons.
