ている。 Hereinafter, the above-mentioned top plate 6 (or 2) will be explained in detail with reference to FIGS. 6 to 8. That is, the sixth
As shown in the figure, the top plate 6 is constructed by adhering a decorative board 6b to one side of a multi-layer veneer board 6a, and then applying resin coating thereon to form a coating film 6c.
Moreover, the multi-layer veneer board 6a is manufactured as follows. That is, a roll RO for manufacturing veneer as shown in FIG. 7 is obtained by thinly peeling wood such as cedar, which is produced in a specific region and has excellent strength and shrinkage, in the same way as radish is peeled. The unit plywood board 6a 1 is made so that the node CL is not included from this roll RO,
6a 2 .

点でも問題であつた。 Here, the reason why the unit plywood boards 6a 1 , 6a 2 ... are cut out from the roll RO so that the knots CL are not included is that defects such as knots CL appear as X-ray images, so accurate X-ray diagnosis is not possible. This is due to the fact that this is not possible, but another reason is that even if you obtain a unit veneer board that does not contain defects such as knots as much as possible, there will still be small defects, so it is necessary to use multiple layers to hide the defects. I'm going. For this reason, the yield from wood such as cedar grown in specific regions, which is an expensive material with excellent strength and shrinkage properties, is extremely low, and it is difficult to use resources effectively and in terms of cost. But it was a problem.

すく、問題であつた。 Further, since only one side of the plywood board 6a forming the main part is coated with a resin and the main part is made of multi-layered plywood, it tends to warp due to moisture absorption, which is a problem.

た。(Problems to be Solved by the Invention) As described above, in the conventional technology, multi-laminated plywood, which forms the main part with few defects, is constructed by cutting out plywood from expensive wood. However, since only one side is coated with resin and the main part is made of multi-layered plywood, it tends to warp due to moisture absorption, which is a problem.

ら得るまでもないのでコストも低い。(Function) According to this configuration, since the medium-density fiberboard that forms the main part is made by solidifying wood fibers with resin, there is no defect that appears in an X-ray image, and the medium-density fiberboard Since the board is made of isotropic material and the decorative boards are glued on both sides, no warpage occurs, and the cost is low because the wood fibers used as raw materials do not need to be obtained from expensive wood.
（実施例）
以下本発明にかかる被検者支持用天板の一実施
例を第１図及び第２図を参照して説明する。(Example) An example of a top plate for supporting a subject according to the present invention will be described below with reference to FIGS. 1 and 2.
本実施例では、被検者支持用天板１２の主要部

している。 In this example, as shown in FIG. 1, the main part of the top plate 12 for supporting the subject is made of wood fibers obtained from lauan coniferous trees with a specific gravity of 0.6 to
0.65 medium density fiberboard 10 is used, and as shown in FIG. 2, decorative boards 11a and 11b impregnated with melamine resin are bonded under pressure to both surfaces of the medium density fiberboard 10.
このような構成によれば、主要部をなす中質繊
維板１０は、木質繊維を樹脂により固化したもの
であるため、Ｘ線像として現われる欠陥は無いも
のである。 According to such a configuration, since the medium density fiberboard 10, which constitutes the main part, is made by solidifying wood fibers with resin, there are no defects that appear in an X-ray image.
また、中質繊維板１０は材質的に等方性材料で

ラミン樹脂を含浸した化粧板１１ａ，１１ｂは、
表面硬度が高いので表面に傷が付きにくいという
利点がある。 In addition, since the medium density fiberboard 10 is an isotropic material and the decorative boards 11a and 1b are bonded on both sides, there is no difference in expansion rate due to changes in temperature and humidity on both sides, and therefore warping is prevented. Does not occur. In this case, the decorative boards 11a and 11b impregnated with melamine resin are
It has the advantage that the surface is hard to scratch because of its high surface hardness.
さらに、原材料である木質繊維は高価な木材で
ないラワン針葉樹等から得るものなので、コスト
も低い。 Furthermore, the cost is low because the wood fiber that is the raw material is obtained from lauan softwood, etc., which is not an expensive wood.

する。 Here, there is a concern that the top plate 12 of this embodiment is inferior in strength compared to the conventional example, but for the following reasons, no problem will occur when it is installed in an X-ray imaging device. I can explain. That is, the fifth
In the bed frame 5 shown in the figure, it is the area S in the figure that is approximately in the center that is actually used as the photographing area. In other words, if there are no obstacles within this region S, there will be no hindrance to X-ray photography. Therefore, if there is a concern about the strength of the top plate 12 of this embodiment,
As shown in FIG. 3, reinforcing members 13a,
13b, and the top plate 12 is supported by the outer periphery of the frame 13 and the reinforcing members 13a, 13b.
