In the manufacturing method of the first invention, the print image creation step can be easily realized by using a digital camera and a computer. Image processing may be performed using general-purpose software, and editing may be performed according to the size of the plate, etc. Simple dedicated software specialized for the implementation of the present invention can be developed and used. is there. As a specific procedure, a photograph of what should be the first decorative pattern is taken with a digital camera, the photograph data is taken into a computer, and an image for the second decorative pattern selected from the pre-stored images is taken. Create a print image in combination with the data.
In addition to the method obtained by taking a picture using a digital camera, it is also possible to use a photograph data obtained by scanning an existing photograph.

Next, the printing process can be carried out by a general-purpose inkjet printer or the like as long as it can process a printing object having a certain thickness.
Further, the printing step uses a transparent plate, forms a printing portion by performing printing in an inverted pattern state on the surface that is the back side opposite to the front side that protrudes in the molding step, It is preferable to carry out by forming a white film on the surface of the printing part.
In this case, since there is no layer of the printed part on the front side of the three-dimensional part protruding from the three-dimensional decorative plate, and there is only on the back side, it is possible to prevent the problem that the printed part is peeled off over time. it can. In addition, the formation of the white coating can improve the color state from the outside of the printing unit, and can prevent the printing unit from being peeled off during molding.

  In addition, as a flat plate made of the thermoplastic resin serving as a substrate of the three-dimensional decorative plate, various types of plates can be used as long as they are flat plates made of a thermoplastic resin having a printable surface. For example, what is called a heat spreadable film in which a recording sheet is laminated on a thermosoftening resin sheet made of PET, vinyl chloride or the like described in Patent Document 1 described above can be used.

  In addition, the upper mold, the lower mold, and the intermediate mold added as necessary can be made of various materials such as gypsum, porous resin, rubber, and ceramics. In addition, the air permeability of each mold can be utilized by utilizing the holes inherent in the material, or by providing a communication hole that communicates from the front side surface to the back side surface of the mold.

The three-dimensional decorative plate according to the second aspect of the present invention is configured such that a part of the peripheral portion is folded back to form a leg portion, and the leg portion and the end portion of the peripheral portion are placed on the mounting surface, so that the three-dimensional portion is substantially in front. It is preferable to be configured to be able to be placed so as to face (claim 3).
In this case, using the fact that the three-dimensional decorative plate is composed of a plate mainly made of resin, it is possible to realize a standing state by itself. Therefore, the added value of the product can be further increased.

  In addition, the outer shape of the peripheral portion is a rectangle, and the solid portion is formed in the center of the first region, which is one region divided by a line segment that bisects the rectangle, and is divided by the line segment. The second region, which is the other region, is provided with a slit for forming the leg portion, and the line segment is a slit or groove for folding so that the first region and the second region can be folded. And a joining means for joining the first region and the second region when the first region and the second region are folded is disposed on the back side surface of the first region or the second region. (Claim 4).

In this case, since the first region and the second region can be overlapped, the rigidity of the entire three-dimensional decorative plate can be increased, and the added value of the product can be further increased.
As the joining means, a notch may be provided in the peripheral portion so as to form a mechanically hooking structure, or an adhesive means such as a double-sided tape may be used.

Example 1
Embodiments of the three-dimensional decorative plate and the manufacturing method thereof according to the present invention will be described with reference to the drawings.
As shown in FIG. 6, the three-dimensional decorative plate 1 of this example includes a flat plate-like peripheral portion 10 and a three-dimensional portion 2 that is formed by protruding from the peripheral portion 10, and the three-dimensional portion 2 is a first decorative pattern. The first raised portion 21 in the vicinity of 11 and the second raised portion 22 having a protruding shape different from that of the first raised portion 21 are combined.
In this example, a human face photograph is adopted as the first decorative pattern 11. Also, as the second decorative pattern around it, a cow's body named after the zodiac was adopted, and it included a pattern that expressed this in a comic style.
The peripheral shape of the peripheral portion 10 is a rectangle, and the overall shape is a postcard-sized card shape.

In manufacturing the three-dimensional decorative plate 1, as shown in FIG. 1, a print image creating step S1, a printing step S2, and a forming step S3 are performed. Further, in the molding step S3, a mold configuration step S31, a heating step S32, and a transfer step S33 are performed.
Further details will be described below.

  The print image creation step S1 takes a photograph of a child's face using a digital camera, captures the photograph data into a computer, and displays a cartoon image of the cow's body selected from pre-saved images. A print image was created in combination with image data for the second decorative pattern including Further, in this example, the print image is converted into image data with the front and back reversed.

Next, in the printing step S2, a transparent plate made of a thermoplastic resin having a size of approximately a postcard size was set in a general-purpose inkjet printer, and the printed image was printed. At this time, the printing surface of the plate was performed with respect to the surface which becomes the back side surface inside the three-dimensional part 2 to be molded later.
Next, a white resin film (not shown) made of a thermoplastic resin was attached to the back side surface of the plate 100. As a result, as shown in FIG. 2, a flat plate on which a print image including a first decorative pattern 11 and a second decorative pattern 12 arranged around the first decorative pattern 11 is printed on a flat plate. 100 is obtained. In this example, since the background pattern is also printed around the second decorative pattern 12, the entire surface of the plate 100 is a printing unit.

Next, in the molding step S3, first, a mold configuration step S31 is performed.
In this example, as shown in FIGS. 3 (a) and 3 (b), it corresponds to the lower mold 31 having a raised shape corresponding to the cow body of the second decorative pattern 12 and the child's face of the first decorative pattern 11. Then, the upper die 32 having a shape protruding from the nose portion 321 as a vertex and projecting in a spherical shape around the nose portion 321 is prepared. Both the upper mold 32 and the lower mold 31 are made of gypsum, and are provided with a large number of communication holes (not shown) for providing air permeability from the front side surface to the back side surface. The upper die 32 and the lower die 31 are provided with a plurality of engaging protrusions 325 and engaging recesses 315, respectively, and the two are positioned by combining them.

Next, a heating step S32 and a transfer step S33 are performed.
In this example, a known apparatus described in Patent Document 1 described above was used as an apparatus for performing these steps. As shown in FIG. 4, the apparatus includes a heater 51 for heating the plate 100, a guide 52 for holding the plate 100 and moving it up and down, and a mold for placing the mold 3. It has a mounting table 53. The mold placing table 53 is connected to a vacuum pump (not shown) and configured to be able to suck from the back side surface of the placed mold 3.

  Using this apparatus, as shown in FIG. 4, first, the heating step S <b> 32 is performed in which the plate 100 and the heater unit 51 are arranged facing each other and the plate 100 is heated and softened. At this time, the back side surface 102 of the plate 100 is a surface on which printing is performed and a white resin film is further attached.

  Next, after the plate 100 is in a softened state, the guide portion 52 that holds the plate 100 is lowered to bring the plate 100 closer to the mold 3. Then, as shown in FIG. 5 (a), the plate 100 is deformed along the surface of the mold 3 and sucked from the back surface of the mold 3, thereby forming the plate 100 and the mold as shown in FIG. 5 (b). The shape of the molding die 3 is transferred by bringing the die 3 into close contact.

After finishing the transfer step S33, the plate 100 was removed from the guide portion 52, and the three-dimensional decorative plate 1 of this example was obtained.
As shown in FIG. 6, the three-dimensional decorative plate 1 includes a flat plate-like peripheral portion 10 and a three-dimensional portion 2 that is projected from the peripheral portion 10 as described above. In the three-dimensional part 2, the first raised part 21 in the vicinity of the first decorative pattern 11 has a substantially spherical shape with the nose part imagining a child's face as a vertex. Moreover, the 2nd protruding part 22 with a smaller protrusion amount than the 1st protruding part 21 is formed in the body part of the cow in the surrounding 2nd decorative pattern 12 in accordance with the outline. And by having the three-dimensional part 2 which combined these 1st protruding part 21 and the 2nd protruding part 22, the three-dimensional decorative plate 1 of this example is more realistic than the case of the plate which only printed the decorative pattern. Can increase product value.

What should be noted in this example is that a combination of the lower mold 31 and the upper mold 32 is adopted as the mold 3.
For this reason, when the shape of the three-dimensional part 2 is to be changed, for example, the second decorative pattern 12 is changed from a cow body pattern to a human child body pattern or another animal or character body pattern, When it is desired to change the shape of the two raised portions 22 to a shape corresponding to the design, only the lower mold portion 31 is changed and the molding die 3 is reassembled.
Further, when it is desired to change the first decorative pattern 11 to an animal face or the like, the upper die 32 may be changed and the molding die 3 may be reassembled.

Thus, the desired three-dimensional shape of the three-dimensional part 2 can be selected from A × B types if the number of types of the lower mold 31 is A and the number of types of the upper mold 32 is B. Is possible. Furthermore, since it can be realized only by changing the combination of the upper die 32 and the lower die 31, no particularly complicated work is required at the time of molding.
As described above, according to this example, a specific three-dimensional shape can be easily selected according to the type of photo data used for the decorative pattern and the surrounding decoration, and various three-dimensional shapes can be used. You can make ingenuity.

  In the above manufacturing method, the device has been devised in order to accurately match the molding die 3 with the portion of the plate 100 to be molded. Specifically, as shown in FIG. 7A, scales X1 and Y1 serving as coordinate axes are carved in the vertical and horizontal directions of the guide portion 52 that holds the plate 100, and the printed decorative pattern is printed when the plate is held. The coordinate positions of the characteristic portions P11 and P12 such as the nose are determined. Further, as shown in FIG. 7B, coordinate axes X2, Y2 and a grid-like line that coincide with the coordinate axis of the guide portion 52 are also engraved on the mold mounting table 53, so that the position on which the mold is mounted is accurately determined. To be able to grasp. As a result, as shown in the figure, when the mold 3 is placed on the mold mounting table 53, the characteristic portions P11 and P12 of the plate 100 and the corresponding coordinates of the characteristic portions P21 and P22 of the mold 3 are shown. By arranging the mold 3 so that the positions coincide, the molding position can be accurately managed.

(Example 2)
As shown in FIG. 8, this example is an example in which a second decorative pattern 13 that images the body of a dog is employed instead of the second decorative pattern 12 that images the body of a cow in Example 1.
In this case, the shape of the second raised portion 21 of the first embodiment described above does not match the second decorative pattern 13. On the other hand, since the first decorative pattern 11 is a child's face photograph, it may be the same as in the first embodiment.
In this case, as shown in FIG. 9, the above-described mold configuration step S31 is performed so as to configure a mold 301 in which the lower mold 31 of the first embodiment is changed to a lower mold 33 having a different shape. Others are the same as in the first embodiment. Thus, in this example, even when the second decorative pattern is changed, it can be easily handled.

FIG. 10 further shows a raised photograph corresponding to the first decorative pattern of the face photograph of the dog, which is a pet, and has a protruding height lower than that of the first embodiment, and the shape of the nose 341 is rounded. This is an example in which the molding die 302 is configured by adopting the upper die 34 that has been changed to a tinged shape. The lower mold 33 is the same as described above.
Further, FIG. 11 is a face photograph of a dog as a pet, but is an example in which a slightly larger shape is adopted than in the case of FIG. In this case, an intermediate die 35 is added between the upper die 34 and the lower die 33, and the protruding height of the upper die 34 is increased to constitute the molding die 303.
Thus, various shapes can be adopted as the mold. Moreover, although the example which divides | segments a shaping | molding die into multiple in the thickness direction was shown in the example mentioned above, further, for example, the said lower mold | type can also be divided | segmented in the width direction. Thereby, the variation of the combination of a type | mold increases further, and it becomes easy to respond to each request.

(Example 3)
This example is an application example in which the plate shape of Example 1 is changed.
That is, as shown in FIG. 12, in the three-dimensional decorative plate 102 of this example, the outer shape of the peripheral portion 10 is a rectangle, and the first region R1 is one region divided by a line segment C that bisects the rectangle. A three-dimensional part 2 is formed at the center. In the second region R2, which is the other region divided by the line segment C, a leg forming slit D is provided. The line segment C is provided with a folding slit for folding the first region R1 and the second region R2. The manufacturing method of the three-dimensional decorative plate 102 is the same as that of the first embodiment except that a plate provided with the respective slits in advance is used.

A double-sided tape as the joining means 4 (FIG. 13) is disposed on the back side surface of the three-dimensional decorative plate 102.
As shown in FIG. 13, the three-dimensional decorative plate 102 obtained in this way bends the first region R <b> 1 and the second region R <b> 2 around the line segment C, overlaps them, and joins them together by the joining means 4. . Moreover, the leg part 19 inside the slit D in 2nd area | region R2 is caused. Thereby, the three-dimensional decorative plate 102 can be placed so that the three-dimensional part 2 faces substantially front by placing the lower end 18 and the leg 19 of the peripheral part on the placement surface.
In other respects, the same effects as those of the first embodiment can be obtained.
