The support surface 41 closes the hole 23 on the front side of the base material 2 and supports the reinforcing member 32 attached to the coating layer 31 from the back side. The translucent member 4 is formed of, for example, a transparent resin (urethane resin or the like) cured in the holes 23.

2B and 2C are views showing a state in which the component 1 is attached to the surface of an arbitrary object 7. A space is provided on the surface of the object 7 corresponding to the hole 23 of the base material 2, and the light source 8 is arranged in the space. The light source 8 is fixed to the object 7 by an attachment device (not shown) or the like. The light source 8 includes, for example, a light emitting element such as an LED and a light guide plate that disperses the light emitted from the light emitting element to emit surface light. The light emitting surface of the light source 8 is close to or in contact with the surface 22 on the back side of the base material 2 where the holes 23 are located. When the light emitting surface of the light source 8 comes into contact with the light transmitting member 4 of the hole 23, the light transmitting member 4 is supported from the back side, so that the displacement of the light transmitting member 4 in the thickness direction is easily suppressed.

On the other hand, in the example of FIG. 2C, the light guide member 81 is arranged between the light source 8 and the hole 23. The light guide member 81 guides the light generated by the light source 8 to the holes 23 formed in the surface 22 on the back side of the base material 2. The light guide member 81 is formed of a material having translucency (acrylic resin, polycarbonate resin, glass, etc.). The front surface of the light guide member 81 contacts the back surface 22 of the base material 2 where the holes 23 are located, and the back surface of the light guide member 81 contacts the light emitting surface of the light source 8. Since the light transmitting member 4 of the hole 23 is supported from the back side by the light source 8 via the light guide member 81, the displacement of the light transmitting member 4 in the thickness direction is easily suppressed.

The generator and the detector may be one in which an electromagnetic wave generation function and a detection function are integrated, such as a non-contact IC card reader / writer or a communication device.

As shown in FIG. 2C, when the light guide member 81 is provided between the back surface 22 of the base material 2 and the light source 8, a gap is formed between the back surface 22 and the light source 8. The generated generator or detector may be arranged in this gap.
By arranging the generator described above in the gap between the surface 22 on the back side of the base material 2 and the light source 8, the object and the generation are located on the front side of the component 1 as compared with the case where the generator is arranged on the back side of the light source 8. You can get closer to the vessel. Therefore, it becomes easy to exert a physical action on the object on the front side from the generator. Further, by arranging the generator in this gap, the distance between the hole 23 and the place where the physical action by the electromagnetic wave or the like is exerted on the front side of the component 1 can be shortened. Therefore, the place where the physical action is exerted on the front side of the component 1 can be easily grasped by lighting the hole 23.
On the other hand, by arranging the above-mentioned detector in the gap between the surface 22 on the back side of the base material 2 and the light source 8, an object located on the front side of the component 1 as compared with the case where the detector is arranged on the back side of the light source 8. Can be brought closer to the detector. Therefore, it becomes easy to increase the detection sensitivity of the physical action from the object in the detector. Further, by arranging the detector in this gap, the distance between the hole 23 and the place where the physical action due to the electromagnetic wave or the like can be detected on the front side of the component 1 can be shortened. Therefore, the location on the front side of the component 1 where the physical action can be detected can be easily grasped by lighting the hole 23.

3A to 3C and 4A to 4D are views for explaining an example of a manufacturing method of the component 1 according to the present embodiment, and show cross sections in each manufacturing process. The manufacturing method of the component 1 is roughly divided into a step of forming the covering member 3 (FIG. 3A), a step of forming the base material 2 (FIGS. 3B to 3C), and a step of attaching the covering member 3 to the base material 2. It includes a step of matching (FIG. 4a), a step of forming the translucent member 4 (FIGS. 4B to 4C), and a step of forming the surface layer 6 (FIG. 4D).

At the stage of forming the covering member 3, first, the covering layer 31 and the reinforcing member 32 are prepared and bonded as shown in FIG. 3A. Here, assuming that the coating layer 31 is a veneer and the reinforcing member 32 is Japanese paper, the Japanese paper is placed on a hot press machine, and after spraying an adhesive (such as a urea resin adhesive) on the Japanese paper, The veneers are laid out on the Japanese paper sprayed with the adhesive, and the Japanese paper and the veneers are pressed and heated by a hot press machine.

When the reinforcing member 32 is a stack of a plurality of Japanese papers, the reinforcing member 32 in which the Japanese papers are adhered to each other is created by repeating the same method as described above. That is, Japanese paper is placed on a hot press machine, the adhesive is sprayed on the Japanese paper, another Japanese paper is laid on the Japanese paper sprayed with the adhesive, and the Japanese papers are pressed against each other by the hot press machine. Heat. The reinforcing member 32 is created by repeating this process for the number of Japanese papers to be repeated. Then, the created reinforcing member 32 and the veneer are finally bonded by a hot press machine.

At the stage of forming the base material 2, the base material 2 is processed to have holes 23. For example, when the base material 2 is a wood board such as plywood, holes 23 are formed in the base material 2 by using a processing device such as an NC router. In FIG. 3B, the place where the hole 23 is formed in the base material 2 by a processing device or the like is represented by a dotted frame. FIG. 3C shows the base material 2 after the holes 23 have been drilled.

At the stage of bonding the covering member 3 to the base material 2, the back side surface of the reinforcing member 32 in the covering member 3 is covered with the front side surface 21 of the base material 2 so that the covering member 3 covers the front side surface 21 of the base material 2. (Fig. 4A).

For example, when the coating layer 31 is a veneer and the reinforcing member 32 is one or more sheets of Japanese paper, the base material 2 having the holes 23 formed is placed on a cold press machine and adhered to the front surface 21 of the base material 2. After spraying the agent (vinyl acetate adhesive, etc.), the coating member 3 is arranged on the front surface 21 of the base material 2 on which the adhesive is sprayed, and the base material 2 and the reinforcing member 32 are pressed by a cold press machine. Press.

At the stage of forming the translucent member 4, as shown in FIG. 4B, a translucent liquid resin with the back surface 22 of the base material 2 to which the covering member 3 is not adhered faces upward. (Transparent urethane resin, epoxy resin, UV resin, etc.) is injected into the hole 23. After injecting the resin, the resin is cured in this state to form the translucent member 4 in the holes 23 (FIG. 4C).

At the stage of forming the surface layer 6, for example, coating with a transparent material (urethane coating, UV coating, piano coating, etc.) is applied to the surface of the component 1 (the front surface surface of the coating layer 31) after the translucent member 4 is formed. The surface layer 6 is formed by lacquer or the like).

As described above, according to the present embodiment, the coating layer 31 is attached to the reinforcing member 32 and is attached to the base material 2 via the reinforcing member 32. Since the base material 2 may be made of an opaque material, a combination of the coating layer 31, the reinforcing member 32, and the base material 2 (for example, veneer, Japanese paper, wood board, etc.) that can be firmly attached by a method using an adhesive or the like. It becomes easier to select (combination of). As a result, the coating layer 31 can be made difficult to peel off from the base material 2 without protecting the front side of the coating layer 31 with a thick resin, glass, or the like. Good durability can be ensured without impairing.

Further, according to the present embodiment, since the reinforcing member 32 is supported from the back side by the support surface 41 of the translucent member 4 provided in the hole 23, even if the coating layer 31 is pushed from the front side of the hole 23, the hole The covering layer 31 and the reinforcing member 32 do not fall into the 23, and the deformation of the covering layer 31 can be effectively prevented.

Further, according to the present embodiment, since the support surface 41 that closes the hole 23 is flush with the front surface 21 of the base material 2, the coating layer at the boundary between the hole 23 and the translucent member 4 The step of 31 can be made minute, and the position of the hole 23 can be made inconspicuous when viewed from the front side.

Further, according to the present embodiment, with the back surface 22 of the base material 2 facing upward, a liquid resin having translucency is injected into the holes 23 and cured (FIGS. 4B and 4C). ), It is possible to make it difficult for a step to occur at the edge of the hole 23 on the front surface 21 of the base material 2.

Next, some modifications of the component 1 and the manufacturing method thereof according to the present embodiment will be described.

5A to 5D are views showing a modified example of the structure of the hole 23 formed in the base material 2. FIG. 5B shows an example of a base material 2A in which a hole 23 having a regulation surface 231 is formed, and FIG. 5A shows an example of a component 1 having the base material 2A shown in FIG. 5B. The inner surface of the hole 23 shown in FIG. 5B in contact with the light transmitting member 4 includes a regulating surface 231 that regulates the displacement of the light transmitting member 4 in the thickness direction. As shown in FIG. 5B, the normal vector Vn of the regulation surface 231 includes a vector component in the direction from the back side to the front side (direction from the bottom to the top in the figure). By providing such a regulation surface 231 on the inner surface of the hole 23 in contact with the translucent member 4, even if the coating layer 31 is pushed from the front side of the hole 23, the translucent member 4 is less likely to be displaced toward the back side. Durability can be increased. In particular, even when the size of the translucent member 4 is increased due to the increase in the size of the hole 23, the light-transmitting member 4 is less likely to fall out of the hole 23 because the regulation surface 231 of the hole 23 supports the translucent member 4. Therefore, the translucent member 4 can be firmly fixed to the base material 2.

Further, the regulation surface 231 shown in FIG. 5B extends from the edge of the hole 23 toward the inside of the hole 23 when viewed from the front side of the base material 2. As a result, the displacement (displacement in the back side direction) of the portion of the translucent member 4 near the edge of the hole 23 is easily regulated by the regulation surface 231. Therefore, a step at the boundary between the hole 23 and the translucent member 4 Can be made less likely to occur.

5C and 5D are views showing still another modification of the structure of the holes 23 formed in the base material 2. A regulation surface 232 inclined obliquely with respect to the thickness direction is formed on the inner surface of the hole 23 of the base material 2B shown in FIG. 5C. Further, on the inner surface of the hole 23 of the base material 2C shown in FIG. 5D, a plurality of regulation surfaces 233 are formed at different positions in the thickness direction. Since the normal vectors of these regulation surfaces 232 and 233 all contain vector components in the direction from the back side to the front side, the translucent member 4 is less likely to be displaced toward the back side.

FIG. 6A is a diagram showing another modified example of the component 1 according to the present embodiment. The component 1 shown in FIG. 6A has a support member 5 fixed to the base material 2 in addition to the base material 2, the covering member 3, and the translucent member 4 already described. The support member 5 is formed of a member having translucency (for example, acrylic resin), and supports the translucent member 4 from the back side. In the example of FIG. 6A, the support member 5 is embedded in the back side of the light transmitting member 4 so as to be in contact with the light transmitting member 4 in the base material 2, and the back surface (outer surface 52) of the support member 5 is the base material 2. It is flush with the back surface 22.

6B and 6C are views showing a state in which the component 1 shown in FIG. 6A is attached to the surface of an arbitrary object 7, and a light source 8 similar to that in FIGS. 2B and 2C is arranged on the back side of the component 1. There is.
In the example of FIG. 6B, the light emitting surface of the light source 8 is close to or in contact with the surface on the back side of the support member 5. When the light source 8 comes into contact with the support member 5, the light transmitting member 4 is supported by the light source 8 via the support member 5, so that the displacement of the light transmitting member 4 in the thickness direction is easily suppressed. In particular, even when the size of the translucent member 4 is increased due to the increase in the size of the hole 23, the support member 5 fixed to the base material 2 supports the translucent member 4 from the back side, so that the translucent member 4 is supported. Is difficult to fall out of the hole 23, so that the light transmitting member 4 can be firmly fixed to the base material 2. Further, when the cross-sectional area of the translucent member 4 (the area of the cross section perpendicular to the thickness direction) becomes large, the central portion of the translucent member 4 away from the edge of the hole 23 is likely to be bent, but the base material 2 Since the support member 5 fixed to the light-transmitting member 4 supports the light-transmitting member 4 from the back side, the occurrence of such deflection can be suppressed, so that an appropriate strength of the light-transmitting member 4 can be ensured.

In the example of FIG. 6C, the light guide member 81 is arranged between the light source 8 and the support member 5. The back surface of the support member 5 contacts the front surface of the light guide member 81, and the back surface of the light guide member 81 contacts the light emitting surface of the light source 8. Since the light transmitting member 4 is supported from the back side by the light source 8 via the supporting member 5 and the light guide member 81, the displacement of the light transmitting member 4 in the thickness direction is easily suppressed.

7A to 7C are diagrams for explaining an example of a manufacturing method of the component 1 shown in FIG. 6A. In the manufacturing method of the component 1 shown in FIG. 6A, a step of forming the support member 5 is further added to the manufacturing methods already described (FIGS. 3A to 3C and 4A to 4D).

After the resin injected into the holes 23 is cured (FIG. 4C), the region including the holes 23 on the back surface of the base material 2 is scraped toward the front side together with the resin (translucent member 4) toward the front side. A recessed recess is formed on the back surface 22 of the base material 2. The dotted frame in FIG. 7A shows a portion to be cut to form a recess on the back surface of the base material 2. A machine tool such as an NC router is used for the processing of scraping the back surface of the base material 2.

After forming a recess on the back surface of the base material 2, a support member 5 having transparency that can be fitted into the recess is prepared (FIG. 7B). The support member 5 is created so as to be aligned with the recess. Then, the created support member 5 is arranged in the recess so as to close the hole 23 of the base material 2 and come into contact with the resin (translucent member 4), and the support member 5 is adhered to the recess (FIG. 7C).

According to the above-described modification provided with the support member 5, even if the resin (translucent member 4) falls into the hole 23 as the volume of the resin decreases after curing, the back side of the base material 2 is provided. The support member 5 is fitted into the recess formed by scraping the surface 22 of the surface 22, and the support member 5 is adhered to the recess in a state of being in contact with the resin (translucent member 4). As a result, the cured resin (translucent member 4) is reliably supported from the back side by the support member 5, so that the resin (translucent member 4) is displaced when the coating layer 31 is pushed from the front side of the hole 23. Can be effectively suppressed. In particular, even when the size of the translucent member 4 is increased due to the increase in the size of the hole 23, the support member 5 adhered to the recess of the base material 2 supports the translucent member 4 from the back side, thereby transmitting light. Since the member 4 is less likely to fall out of the hole 23, the translucent member 4 can be firmly fixed to the base material 2. Further, even when the cross-sectional area of the translucent member 4 (the area of the cross section perpendicular to the thickness direction) becomes large, the support member 5 adhered to the recess of the base material 2 supports the translucent member 4 from the back side. Since the occurrence of deflection of the translucent member 4 can be suppressed, an appropriate strength of the translucent member 4 can be ensured.
Further, according to the above-described modification including the support member 5, the inner surface 51 of the support member 5 is in contact with the translucent member 4 and closes the hole 23 from the back side, and the outer surface 52 of the support member 5 is the base material 2. It is flush with the surface 22 on the back side of the. As a result, the outer surface 52 of the support member 5 is supported from the back side by another object in contact with the back surface 22 of the base material 2 in a state where the inner surface 51 of the support member 5 is in contact with the back surface of the translucent member 4. It will be easier. Therefore, the displacement of the translucent member 4 when the coating layer 31 is pushed from the front side of the hole 23 can be suppressed more effectively.
