Abstract

<P>PROBLEM TO BE SOLVED: To provide an display plate for a watch, which is easily formed and regulates the rotation of a base without affecting a substrate. <P>SOLUTION: An attachment part 10a of the base 10 consists of a column with a rectangular cross section, the corner part of which consists of curved surfaces. A pore 16a provided in the substrate 16 is formed so that it regulates the rotation of the base according to the attachment part 10a. Thereby, when the attachment part 10a of the base 10 is fitted into the pore 16a of the substrate 16, the rotation is regulated since the external surface of the attachment part 10a and the inner surface of the pore 16a abut on each other in the rotation direction. Since the corner part is formed as a curved surface, the forces at the time of engagement are prevented from concentrating onto the corner part of the pore 16a of the substrate 16 and causing damage. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、ダイヤモンド等の貴石を固定する台座が取り付けられた時計用表示板に関するものであり、特に、台座の位置規制を簡単かつ確実に行なうことを可能にするものに関する。 The present invention relates to a timepiece display board to which a pedestal for fixing a precious stone such as diamond is attached, and more particularly, to one that enables simple and reliable position regulation of a pedestal.

従来、貴石を固定する台座が取り付けられた時計用表示板は、図１４及び図１５に示すような構造からなるものであった。この時計用表示板では、基板２に設けられた円形の孔２ａに、台座４の下部に設けられた円柱状の取付部４ａを嵌め込むことにより、台座４を基板２に取り付けていた（例えば、特許文献１参照）。また、この台座４の上部には、貴石６を保持する円筒形状をなす保持部４ｂが設けられており、その周状壁を内方にかしめたり、その弾性によって貴石６を保持するものとなっていた。 Conventionally, a timepiece display board to which a base for fixing a precious stone is attached has a structure as shown in FIGS. In this watch display board, the pedestal 4 is attached to the substrate 2 by fitting the columnar attachment portion 4a provided at the lower portion of the pedestal 4 into the circular hole 2a provided in the substrate 2 (for example, , See Patent Document 1). Further, a holding portion 4b having a cylindrical shape for holding the precious stone 6 is provided on the upper portion of the pedestal 4, and the peripheral wall is caulked inward or the precious stone 6 is held by its elasticity. It was.

この台座４は、下部の取付部４ａだけでなく、上部の保持部４ｂも円筒形状をなすものであるため、基板２に取り付けるときに台座４の軸を中心として回転したとしても保持部４ｂの向きに影響が出ることはない。ところが、図１６に示すように、貴石６を保持する保持部４ｂの平面形状が矩形をなすものであると、台座４がわずかに回転しただけで破線で示す正規位置からずれていることがわかり、回転を規制することが望まれていた。特に、図１７に示すように、時字のように放射状に台座４を取り付ける場合、台座４の向きを個々に定めて取り付けることが必要であり、位置ずれを起こし易い。このため、台座４をこのように配置する場合、保持部４ｂが矩形のものではなく円形をなすものを使用することが多かったが、矩形のものに比べて高級感あるいは目新しさに欠けるという問題があった。
実開平５−８７５９０号公報 Since the pedestal 4 has a cylindrical shape in addition to the lower mounting portion 4a, the upper holding portion 4b also has a cylindrical shape. The direction is not affected. However, as shown in FIG. 16, it can be seen that if the planar shape of the holding portion 4 b that holds the precious stone 6 is rectangular, the pedestal 4 is slightly rotated and deviates from the normal position indicated by the broken line. It was desired to regulate the rotation. In particular, as shown in FIG. 17, when the pedestal 4 is attached in a radial manner like a time character, it is necessary to determine the orientation of the pedestal 4 individually, and the position is likely to be displaced. For this reason, in the case where the pedestal 4 is arranged in this way, the holding part 4b is often a circular one instead of a rectangular one, but there is a problem that it lacks a sense of quality or novelty compared to a rectangular one. was there.

It is attached to the substrate, and the attachment portion and the hole are formed in a suitable shape, and when the attachment portion is fitted into the hole, the rotation of the pedestal is restricted. The substrate of the timepiece display plate is composed of an upper plate and a lower plate, and one or both of the holes provided in the upper plate and the lower plate are formed in a shape that restricts the rotation of the pedestal. . Moreover, the said attachment part consists of a column body whose cross section becomes a polygon or an ellipse. Further, the mounting portion is formed of a pillar body having a polygonal cross section and a corner portion forming a curved surface. Further, the substrate is composed of an upper plate and a lower plate, and holes are provided in the upper plate and the lower plate, respectively, and the mounting portion is inserted into a tip portion fitted into the hole of the lower plate and a hole of the upper plate. One of a shape of the hole of the lower plate and the tip portion, and a shape of the hole of the upper plate and the shape of the root portion is formed to restrict the rotation of the pedestal.

In addition, the tip or root of the mounting portion is a column having a polygonal cross section and a curved corner. Further, the curved surface of the corner portion is composed of a part of the same circle with the axis of the pedestal as the center.

本発明の時計用表示板では、台座下方の取付部と基板の孔を、互いに適合する形状で且つ台座の回転を規制する形状に形成しているので、基板に取り付けた台座がその軸に関して回転することがなく、簡単かつ確実に設定した向きで取り付けることができる。特に、台座の取付部をその横断面が多角形又は楕円となる柱体で形成し、基板の孔をこれと同形状の内部形状とすることで形成し易く且つ確実に台座の回転を規制することができる。 In the timepiece display board of the present invention, the mounting portion below the pedestal and the hole in the substrate are formed in a shape that is compatible with each other and that restricts the rotation of the pedestal, so that the pedestal attached to the substrate rotates about its axis. It can be attached in a set direction easily and securely. In particular, the mounting portion of the pedestal is formed of a column whose cross section is polygonal or elliptical, and the hole of the substrate is formed in the same internal shape as this, and the rotation of the pedestal is reliably regulated. be able to.

また、台座の取付部の横断面と基板の孔の内部形状を多角形に形成した場合に、その角部を曲面、特に台座の軸を中心とする円の一部からなる曲面にすると共に基板の孔も同様に形成することで、角と角が当たる基板の孔の角部の損傷を防ぐことができる。これにより、貝、貴石等の破損し易い材料が表面側に設けられた基板であっても、孔の角部にクラックが入ることがなく、品質を高めることができる。 In addition, when the cross section of the mounting portion of the pedestal and the internal shape of the hole of the substrate are formed in a polygon, the corner portion is curved, in particular, a curved surface consisting of a part of a circle centered on the axis of the pedestal. By forming the holes in the same manner, it is possible to prevent damage to the corners of the holes of the substrate where the corners hit each other. Thereby, even if it is a board | substrate with which the easily damaged material, such as a shellfish and a precious stone, was provided in the surface side, a crack does not enter into the corner | angular part of a hole and quality can be improved.

また、本発明においては、基板を上板と下板で構成した場合、上板と下板にそれぞれ設けた孔の一方又は両方の形状を台座の取付部の形状に合わせて回転を規制する形状に形成している。特に、上板が貝等からなる、下板が金属からなる場合、上板の孔を形成が容易で損傷しにくい形状に形成し、下板の孔を台座の取付部と共に回転規制する形状に形成することで、上板に負担をかけることなく回転規制をして台座を取り付けることができる。 In the present invention, when the substrate is composed of an upper plate and a lower plate, the shape of one or both of the holes provided in the upper plate and the lower plate is matched to the shape of the mounting portion of the pedestal to restrict rotation. Is formed. In particular, when the upper plate is made of shellfish or the like, and the lower plate is made of metal, the hole on the upper plate is formed into a shape that is easy to form and not easily damaged, and the hole on the lower plate is shaped to restrict rotation with the mounting portion of the base. By forming, a base can be attached by restricting rotation without imposing a burden on the upper plate.

本発明の時計用表示板においては、台座の下方に設けられた取付部と基板の孔を適合する形状に形成すると共に、取付部を孔に嵌入したときに台座の回転を規制する形状に形成している。この台座の取付部は、横断面が多角形又は楕円となる柱体からなり、多角形の場合にはその角部が同一円の一部等の曲面からなる。また、基板は、上板と下板からなり、この上板と下板にそれぞれ設けられた孔の一方又は両方の形状を台座の取付部に合わせて台座の回転を規制する形状に形成している。また、上板と下板の孔と、その各孔に嵌入される台座の取付部の根元部と先端部を、それぞれ適合する形状に形成すると共にその一方を台座の回転を規制する形状に形成している。これにより、台座の取付部を基板の孔に嵌入すると台座の取付部の外面と基板の孔の内面が回転方向に当接することで軸に関する回転が規制される。また、台座の取付部の横断面形状と基板の孔の平面形状を多角形に設定しても、その角部を曲面にすることで、基板の孔の角部に嵌入時の力が集中して損傷することを防いでいる。 In the timepiece display panel of the present invention, the mounting portion provided below the pedestal and the hole in the substrate are formed in a suitable shape and the rotation of the pedestal is restricted when the mounting portion is inserted into the hole. is doing. The mounting portion of the pedestal is formed of a column having a cross section of a polygon or an ellipse. In the case of a polygon, the corner is formed of a curved surface such as a part of the same circle. Also, the substrate is composed of an upper plate and a lower plate, and one or both of the holes provided in the upper plate and the lower plate are formed in a shape that regulates the rotation of the pedestal according to the mounting portion of the pedestal. Yes. In addition, the upper and lower plate holes, and the base and tip of the mounting portion of the pedestal that is inserted into each hole are formed in suitable shapes, and one of them is formed in a shape that restricts the rotation of the pedestal. is doing. Accordingly, when the mounting portion of the pedestal is inserted into the hole of the substrate, the rotation of the shaft is restricted by the outer surface of the mounting portion of the pedestal and the inner surface of the hole of the substrate contacting each other in the rotation direction. In addition, even if the cross-sectional shape of the mounting portion of the base and the planar shape of the hole of the board are set to polygons, the corners are curved so that the force at the time of fitting is concentrated at the corner of the hole of the board. To prevent damage.

１０は台座であり、その下方に横断面が矩形をなす角柱体からなる取付部１０ａが設けられている。図３に示すように、この取付部１０ａの角部１０ｂは、台座１０の軸を中心とする円１２（破線部分）の一部に合致する曲面により構成されている。また、この取付部１０ａの中央には、後述する保持部に収められる貴石の先端を逃げるための貫通孔１０ｆが設けられている。また、台座１０の上方には、平面形状が矩形をなす保持部１０ｃが設けられている。この保持部１０ｃの内部には、図２及び図４に示すように、貴石１４の形状に合うように縁部分から中央に向かって下り勾配となる斜面からなる貴石載置部１０ｄが形成されている。また、保持部１０ｃの角部１０ｂには、それぞれ上方に立ち上がる爪部１０ｅが設けられており、図２に示すように、この爪部１０ｅを内方にかしめて貴石１４の一部に被せることにより貴石１４を保持するものとなっている。 Reference numeral 10 denotes a pedestal, below which a mounting portion 10a made of a prismatic body having a rectangular cross section is provided. As shown in FIG. 3, the corner portion 10 b of the mounting portion 10 a is configured by a curved surface that matches a part of a circle 12 (broken line portion) centered on the axis of the base 10. A through hole 10f is provided in the center of the mounting portion 10a for escaping the tip of a precious stone stored in a holding portion described later. In addition, a holding portion 10c having a rectangular planar shape is provided above the pedestal 10. As shown in FIGS. 2 and 4, a precious stone placing portion 10 d made of an inclined surface having a downward slope from the edge portion toward the center is formed inside the holding portion 10 c so as to match the shape of the precious stone 14. Yes. In addition, the corner portion 10b of the holding portion 10c is provided with a claw portion 10e that rises upward. As shown in FIG. 2, the claw portion 10e is caulked inward to cover a part of the precious stone 14. Thus, the precious stone 14 is held.

１６は基板であり、台座１０を取り付ける位置に孔１６ａが形成されている。この孔１
６ａは、台座１０の取付部１０ａに適合するように平面形状が取付部１０ａと同様の矩形をなすと共にその角部も取付部１０ａと同様に曲面をなし、取付部１０ａよりもわずかに大きい相似形状となるように形成されている。 16 is a board | substrate and the hole 16a is formed in the position which attaches the base 10. FIG. This hole 1
6a has a rectangular shape similar to that of the mounting portion 10a so that it fits the mounting portion 10a of the pedestal 10, and its corners are also curved similarly to the mounting portion 10a, and is slightly larger than the mounting portion 10a. It is formed to have a shape.

上記構成からなる台座１０は、次のように基板１６に取り付けられる。はじめに、台座１０の保持部１０ｃの貴石載置部１０ｄに貴石１４を載置し、爪部１０ｅをかしめて貴石１４を台座１０に固定する。次に、基板１６の孔１６ａに台座１０の取付部１０ａを嵌入する。このときに孔１６ａと取付部１０ａの角部１０ｂは、共に曲面をなすものであるため、鋭利な角部がぶつかり合って損傷することを防ぐことができる。このように取付部１０ａを孔１６ａに嵌入する際又は嵌入した後、必要に応じてカシメ、接着、溶接、圧入等の慣用技術を用いて固定する。このように基板１６に台座１０を取り付けると、取付部１０ａと孔１６ａの平面形状が矩形であるため台座１０がその軸に関して回転することが規制される。このため、孔１６ａの位置と向きを予め設定することで、台座１０の位置と向きを簡単かつ精度良く設定することができる。 The pedestal 10 having the above configuration is attached to the substrate 16 as follows. First, the precious stone 14 is placed on the precious stone placing portion 10d of the holding portion 10c of the pedestal 10, and the claw portion 10e is caulked to fix the precious stone 14 to the pedestal 10. Next, the mounting portion 10 a of the base 10 is fitted into the hole 16 a of the substrate 16. At this time, since the hole 16a and the corner portion 10b of the mounting portion 10a are both curved, it is possible to prevent sharp corner portions from colliding and being damaged. As described above, when the mounting portion 10a is inserted into the hole 16a or after the mounting portion 10a is inserted, the mounting portion 10a is fixed using a conventional technique such as caulking, adhesion, welding, or press-fitting as necessary. When the pedestal 10 is attached to the substrate 16 in this way, the planar shape of the attachment portion 10a and the hole 16a is rectangular, so that the pedestal 10 is restricted from rotating about its axis. For this reason, the position and orientation of the pedestal 10 can be easily and accurately set by setting the position and orientation of the hole 16a in advance.

また、上記時計用表示板における基板１６は、金属、プラスチック等からなる一枚の基板であるが、図６に示すように、上板１６ｂと下板１６ｃからなる基板１６を使用しても良い。この基板１６における下板１６ｃは金属板からなり、上板１６ｂは貝、貴石等の素材からなるものであり、それぞれに連通する孔１６ｄ，１６ｅが設けられている。この孔１６ｄ，１６ｅは、前述した孔１６ａと同じ形状に形成されており、台座１０の取付部１０ａを嵌入することで台座１０の回転を規制しつつ基板１６に取り付けることができる。特に、取付部１０ａと孔１６ｄの角部を曲面とすることで、上板１６ｂが貝等の比較的損傷し易い材質で構成されていても、嵌入時の力で過度部にクラックが発生することを防ぐことができる。 Further, the substrate 16 in the timepiece display plate is a single substrate made of metal, plastic or the like, but as shown in FIG. 6, a substrate 16 made of an upper plate 16b and a lower plate 16c may be used. . The lower plate 16c of the substrate 16 is made of a metal plate, and the upper plate 16b is made of a material such as a shell or a precious stone, and is provided with holes 16d and 16e communicating with each. The holes 16d and 16e are formed in the same shape as the above-described hole 16a, and can be attached to the substrate 16 while restricting the rotation of the pedestal 10 by fitting the attachment portion 10a of the pedestal 10. In particular, by making the corners of the mounting portion 10a and the hole 16d curved, even if the upper plate 16b is made of a relatively easily damaged material such as a shell, cracks are generated in the excessive portion due to the force during insertion. Can be prevented.

尚、本実施例では、孔１６ｄ，１６ｅの両方を取付部１０ａの形状に合致する形状に形成しているが、孔１６ｄ，１６ｅの一方だけを取付部１０ａの形状に合致する形状にしても良い。この場合、孔１６ｄ，１６ｅの他方の平面形状は、取付部１０ａが内接する円形等に形成すれば良い。例えば、図７に示すように、上板１６ｂの孔１６ｄを矩形に形成し、下板１６ｃの孔１６ｅを取付部１０ａが内接する円形に形成する。 In this embodiment, both the holes 16d and 16e are formed in a shape that matches the shape of the mounting portion 10a. However, only one of the holes 16d and 16e has a shape that matches the shape of the mounting portion 10a. good. In this case, the other planar shape of the holes 16d and 16e may be formed in a circle or the like in which the attachment portion 10a is inscribed. For example, as shown in FIG. 7, the hole 16d of the upper plate 16b is formed in a rectangular shape, and the hole 16e of the lower plate 16c is formed in a circular shape in which the mounting portion 10a is inscribed.

図８は本発明の実施例２に係る時計用表示板の要部を示す分解斜視図、図９は図８に示す時計用表示板の要部断面図、図１０は図８に示す台座の取付部の底面図、図１１は図８に示す台座の縦断面図、図１２は図１１に示す台座の平面図である。本実施例における時計用表示板は、前述した実施例１と基本的に同様の構成からなるものであるが、上板１６ｂと下板１６ｃからなる基板１６を使用し、更に、その上板１６ｂと下板１６ｃにそれぞれ形成される孔と、各孔に嵌入する台座１０の取付部１０ａの根元部と先端部を、それぞれ適合する形状にすると共に、その一方を台座１０の回転を規制する形状に形成したものとなっている。 8 is an exploded perspective view showing the main part of the timepiece display board according to the second embodiment of the present invention, FIG. 9 is a cross-sectional view of the main part of the timepiece display board shown in FIG. 8, and FIG. 10 is the pedestal shown in FIG. 11 is a bottom view of the mounting portion, FIG. 11 is a longitudinal sectional view of the pedestal shown in FIG. 8, and FIG. 12 is a plan view of the pedestal shown in FIG. The watch display board in the present embodiment has basically the same configuration as that of the first embodiment described above, but uses a substrate 16 composed of an upper plate 16b and a lower plate 16c, and further uses the upper plate 16b. And the bottom plate 16c, respectively, and the base portion and the tip portion of the mounting portion 10a of the pedestal 10 to be fitted into each hole, respectively, and a shape that restricts the rotation of the pedestal 10 at one of them. It has been formed.

即ち、図８及び図９に示すように、本実施例における基板１６は、貝、貴石等からなる上板１６ｂと金属、プラスチック等からなる下板１６ｃにより構成されている。この上板１６ｂと下板１６ｃには、連通すると共に互いに平面形状が異なる孔１６ｇ，１６ｈが設けられている。また、台座１０の取付部１０ａには、孔１６ｇ，１６ｈにそれぞれ嵌入される根元部１０ｇ、先端部１０ｈが設けられている。 That is, as shown in FIGS. 8 and 9, the substrate 16 in this embodiment is composed of an upper plate 16b made of shellfish, precious stones, and the like and a lower plate 16c made of metal, plastic or the like. The upper plate 16b and the lower plate 16c are provided with holes 16g and 16h that communicate with each other and have different planar shapes. Further, the mounting portion 10a of the pedestal 10 is provided with a root portion 10g and a tip portion 10h that are fitted into the holes 16g and 16h, respectively.

本実施例における取付部１０ａの根元部１０ｇは、前述した実施例１の取付部１０ａと同様に、横断面が矩形をなす角柱体からなり、図１０に示すように、その角部が台座１０の軸を中心とする円１２の一部に合致する曲面になっている。また、取付部１０ａの先端
部１０ｈは、その横断面が根元部１０ｇの矩形内に収まる円形をなす円柱体からなる。 The base portion 10g of the mounting portion 10a in the present embodiment is formed of a prismatic body having a rectangular cross section, as in the mounting portion 10a of the first embodiment described above. As shown in FIG. It is a curved surface that matches a part of the circle 12 centered on the axis. Further, the distal end portion 10h of the attachment portion 10a is formed of a circular cylinder whose cross section is within a rectangle of the root portion 10g.

また、本実施例における上板１６ｂの孔１６ｇは、取付部１０ａの根元部１０ｇに適合するように平面形状が根元部１０ｇと同様の矩形をなすと共にその角部も根元部１０ｇと同様に曲面をなし、根元部１０ｇよりもわずかに大きい相似形状となるように形成されている。また、下板１６ｃの孔１６ｈは、取付部１０ａの先端部１０ｈに適合するように平面形状が円形をなし、先端部１０ｈの外形よりもわずかに内径が大きくなるように形成されている。 In addition, the hole 16g of the upper plate 16b in the present embodiment has a rectangular shape similar to that of the root portion 10g so that it fits the root portion 10g of the mounting portion 10a, and its corners are also curved like the root portion 10g. It is formed so as to have a similar shape slightly larger than the root portion 10g. Further, the hole 16h of the lower plate 16c is formed to have a circular planar shape so as to fit the tip portion 10h of the mounting portion 10a, and to have a slightly larger inner diameter than the outer shape of the tip portion 10h.

上記構成からなる取付部１０ａを孔１６ｇ，１６ｈに嵌入すると、先端部１０ｈは上板１６ｂの孔１６ｇを通過して下板１６ｃの孔１６ｈに嵌まり、根元部１０ｇは上板１６ｂの孔１６ｇに嵌まることになる。この構造においては、根元部１０ｇが上板１６ｂの孔１６ｇに嵌入することで台座１０の軸方向への回転を規制し、先端部１０ｈが下板１６ｃの孔１６ｈに嵌入することで台座１０を確実に基板１６に取り付けることができる。尚、本実施例においても、必要に応じてカシメ、接着、溶接、圧入等の慣用技術によって台座１０を基板に固定している。 When the mounting portion 10a having the above configuration is inserted into the holes 16g and 16h, the tip portion 10h passes through the hole 16g of the upper plate 16b and fits into the hole 16h of the lower plate 16c, and the root portion 10g is the hole 16g of the upper plate 16b. Will fit in. In this structure, the base portion 10g is fitted into the hole 16g of the upper plate 16b to restrict the rotation of the pedestal 10 in the axial direction, and the tip portion 10h is fitted into the hole 16h of the lower plate 16c so that the pedestal 10 is fitted. It can be securely attached to the substrate 16. Also in this embodiment, the pedestal 10 is fixed to the substrate by conventional techniques such as caulking, adhesion, welding, press-fitting, etc. as necessary.

上記のように本実施例においては、取付部１０ａの根元部１０ｇ及び先端部１０ｈと上板１６ｂの孔１６ｇ及び下板１６ｃの孔１６ｈがそれぞれ適合しているので、より確実かつ強固に台座１０を基板１６に取り付けることができる。 As described above, in the present embodiment, the base portion 10g and the tip portion 10h of the mounting portion 10a and the hole 16g of the upper plate 16b and the hole 16h of the lower plate 16c are adapted to each other. Can be attached to the substrate 16.

また、取付部１０ａの根元部１０ｇ及び先端部１０ｈと孔１６ｇ，１６ｈがそれぞれ適合すると共にその一方だけで台座１０の回転を規制することができるので、上板１６ｂに貝、貴石等の比較的損傷し易い材料を使用したとしても、上板１６ｂの孔１６ｇの負担を軽減してその損傷を防ぐことができる。例えば、図１３に示すように、取付部１０ａの根元部１０ｇの横断面を円形にすると共に上板１６ｂの孔１６ｇの平面形状を同様の円形に設定し、先端部１０ｈの横断面を矩形にすると共に下板１６ｃの孔１６ｈの平面形状を同様の矩形に設定することで、孔１６ｇを形成し易い形状にすることができると共に台座１０の回転規制による負担を軽減することができる。これによって、上板１６ｂに貝等の素材を使用しても、孔１６ｇを容易に形成することができると共に台座１０の取り付けによるクラックの発生を防ぐことができる。 In addition, since the base portion 10g and the tip portion 10h of the mounting portion 10a and the holes 16g and 16h are fitted, and the rotation of the base 10 can be restricted by only one of them, the upper plate 16b is relatively free of shells, precious stones and the like. Even if a material that is easily damaged is used, the burden on the hole 16g of the upper plate 16b can be reduced and the damage can be prevented. For example, as shown in FIG. 13, the cross section of the base portion 10g of the mounting portion 10a is made circular, the plane shape of the hole 16g of the upper plate 16b is set to the same circular shape, and the cross section of the tip portion 10h is made rectangular. In addition, by setting the planar shape of the hole 16h of the lower plate 16c to the same rectangular shape, it is possible to make the hole 16g easy to form, and to reduce the burden due to the rotation restriction of the base 10. As a result, even if a material such as shellfish is used for the upper plate 16b, the holes 16g can be easily formed and cracks due to the mounting of the base 10 can be prevented.

尚、上記実施例１及び２における取付部１０ａの断面形状と基板１６の孔１６ａ，１６ｄ，１６ｅ，１６ｇ，１６ｈの平面形状は、円形、矩形、楕円形に限定されるものではなく、三角形、五角形等の多角形、あるいは台座１０の回転を規制する形状であればその他の形状であっても良い。 The cross-sectional shape of the mounting portion 10a and the planar shapes of the holes 16a, 16d, 16e, 16g, and 16h of the substrate 16 in Examples 1 and 2 are not limited to a circle, a rectangle, and an ellipse, but a triangle, Any other shape may be used as long as it is a polygon such as a pentagon or a shape that restricts the rotation of the pedestal 10.
