  The invention according to claim 5 is characterized in that the fixing means is a low-viscosity double-sided tape provided on all or a part of the back surface of the three-dimensional decorative sheet that contacts the back surface of the mobile communication terminal. The three-dimensional decorative panel according to claim 1, wherein the three-dimensional decorative panel is provided.

  The invention according to claim 6 is characterized in that at least one of the fixing means is formed by bending inwardly from a side wall portion covering a peripheral side surface of the mobile communication terminal, and a front side peripheral edge and a back side peripheral edge of the side wall portion. The bumper includes a front side locking portion and a back side locking portion, and is a bumper that sandwiches an outer peripheral edge portion of the three-dimensional decorative sheet between a back surface of the mobile communication terminal and the back surface side locking portion. It is a three-dimensional decorative panel in any one of Claims 1-5.

  According to the three-dimensional decorative panel of claim 1, the base sheet and the three-dimensional decorative sheet are separated from other articles such as a bumper at the time of pattern printing on the base sheet and molding of the three-dimensional decorative sheet. Therefore, an extra work (for example, a work for masking a portion that is not decorated) can be omitted at the time of printing / molding, so that work efficiency is improved. As a result, it is possible to give a high-quality decoration with elaborate taste.

  According to the three-dimensional decorative panel of claim 2, the base sheet is made of a thermoplastic resin having excellent weather resistance, surface hardness, three-dimensional formability, and transparency, thereby enabling post-processing such as NC cutting and vacuum forming. Therefore, the possibility of design variation can be expanded.

  According to the three-dimensional decorative panel of claim 3, the three-dimensional decorative sheet can correspond to a variety of small lots and a variety of products as compared with a) injection molding, and the initial cost can be relatively suppressed, and b) male. In molded products, the surface that does not touch the mold can be used as the product surface, so it is possible to create highly glossy products, and c) three-dimensional by vacuum forming that has a high degree of freedom in surface decoration. Since it is processed into a shape, it is possible to form convex and concave portions corresponding to the details on the pattern printed on the base sheet.

  According to the three-dimensional decorative panel of claim 4, the three-dimensional effect is emphasized by the collaboration of the 3D stereoscopic image portion that has been originally printed on the base material sheet and the convex and concave portions that are physically raised by the molding process. Design can be dramatically improved.

  According to the three-dimensional decorative panel of claim 5, the fixing of the three-dimensional decorative sheet to the mobile communication terminal is based on the weak adhesive force of the double-sided tape. Can be removed without the need for In addition, there is little concern that the back of the mobile communication terminal will be stained with adhesive marks even after being re-applied several times.

  According to the three-dimensional decorative panel of the sixth aspect, since the pinching force between the mobile communication terminal and the bumper also acts on the fixing of the three-dimensional decorative sheet to the mobile communication terminal, the fixing can be made stronger. In addition, the three-dimensional decorative sheet and the bumper can be sold separately, which brings about an effect of improving the willingness to purchase by consumers who want to change only the decoration.

  The three-dimensional decorative panel 1 of the present invention includes a three-dimensional decorative sheet 4 that covers the back surface 22 of the mobile communication terminal 2 as a main component, and a double-sided tape 41 in the first embodiment (FIG. 3) as a fixing means. In 2nd Embodiment (FIG. 4), the double-sided tape 41 and the bumper 3 are provided. The mobile communication terminal 2 in the present invention typically includes a multi-function mobile phone (for example, a smartphone).

  As a decorative member, the three-dimensional decorative sheet 4 is formed in the same shape and size in plan view as the back surface 22 of the mobile communication terminal 2 that is the decorated part. The material of the three-dimensional decorative sheet 4 is acrylic (PMMA) resin, polycarbonate (PC), in that it is excellent in weather resistance, surface hardness, three-dimensional formability, transparency and can be post-processed such as NC cutting and vacuum forming. A thermoplastic resin such as an ABS resin is preferable, and polycarbonate is particularly preferable.

  The three-dimensional decorative sheet 4 according to the embodiment of FIG. 3 includes a base sheet 42 made of polycarbonate on which a predetermined pattern (for example, a character such as an animation, a maze, an astronomical map, a sweets image, etc., not shown) is printed. Using a mold manufactured in accordance with the handle, vacuum forming is performed to form a concave portion 43 corresponding to the handle, and then trimming is completed. The method of pattern printing on the base material sheet 42 is not particularly limited, and is performed by, for example, a screen printing method or an offset printing method.

  The 3D decorative sheet 4 according to the embodiment of FIG. 4 forms a 3D stereoscopic image portion 44 by performing 3D printing on the base sheet 42. Specifically, a special microlens is formed on the surface of the material by screen printing, and a fine dot pattern printing is combined on the back surface, so that a 3D stereoscopic image portion 44 is born through the material and the lens. As a result, the stereoscopic effect is enhanced by the collaboration of the 3D stereoscopic image unit 44 and the convex and concave portions 43, and the design is dramatically improved. For 3D printing according to the present embodiment, printing technology “Mino Heart 3D” manufactured by Mino Shoji Co., Ltd. is preferably used.

  The bumper 3 includes a side wall 31, a front side locking part 34 and a back side locking part 35 formed by bending inward from the front side peripheral edge 32 and the back side peripheral edge 33 of the side wall part 31. The inwardly concave shape is formed by the portion 31, the front side locking portion 34, and the back side locking portion 35. The portable communication terminal 2 is covered with the bumper 3 by sandwiching the peripheral side surface 21 of the portable communication terminal 2 in the recess. The back side locking portion 35 is also used to sandwich the outer peripheral edge of the three-dimensional decorative sheet 4 together with the back surface 22 of the mobile communication terminal 2.

  The fixing of the three-dimensional decorative sheet 4 to the mobile communication terminal 2 can be performed only by the clamping force between the back surface 22 of the mobile communication terminal 2 and the back surface side locking portion 35 of the bumper 3. However, it is preferable to use both means in combination in order to make the fixation more reliable. In this case, since the clamping force acts on the three-dimensional decorative sheet 4, a relatively strong adhesive force is not required, and a weakly viscous double-sided tape is sufficient. For this reason, there is little fear that the back surface 22 of the mobile communication terminal 2 is soiled with the traces of the adhesive even after being replaced several times. On the contrary, when the double-sided tape 41 alone is not sufficient for fixing, a thin sponge (not shown) may be laid under the double-sided tape 41. For example, urethane foam “PORON” (registered trademark) is preferably used as the thin sponge.

  In the present embodiment, as a specific example of the decoration applied to the three-dimensional decoration sheet 4, all or a part of a character such as an animation is drawn with the convex portion of the convex concave portion 43, and the 3D stereoscopic image portion 44 is drawn on the background description. The structure using is mentioned. As a result, it is possible to realize a powerful design as if the character had jumped out from the back surface 22 of the mobile communication terminal 2, and it can be expected to improve the willingness of young people to purchase.

  Specific examples of the decoration applied to the other three-dimensional decorative sheet 4 include a configuration in which a maze is constructed by the convex portion of the convex recess 43 and a ball is arranged in the maze. As a result, the mobile communication terminal 2 can be tilted up, down, left and right to roll the ball toward the goal and enjoy the maze, and it can be expected to stimulate the consumer's sense of play and improve purchase motivation.

  As a specific example of the decoration applied to the other three-dimensional decorative sheet 4, a celestial map is drawn with a large celestial object in the vicinity of the convex part of the convex recess 43, and a distant celestial object or a small celestial object with a concave part By combining the 3D stereoscopic image unit 44, a configuration as if it is a celestial model can be given. Furthermore, if this is combined with phosphorescent printing, it is possible to express different faces during the day and night, and it can be expected to improve consumers' willingness to purchase for aesthetic appreciation that goes beyond simple fashion.

  As a specific example of the decoration applied to the other three-dimensional decorative sheet 4, a sweet is drawn on the convex part of the convex concave part 43, and a rhinestone or a design sticker is pasted, and further, a transfer sticker can be used to expand It can be expected to improve the willingness of women who want design and sweets.
