ところで、筆記具の軸体などの成型品は、一般に、プラスチック材料（例えば、ポリプロピレン樹脂）又は無機質材料（例えば、セピオライト）を主な材料として成型されており、プラスチック材のものは、無機質材のものに比べて割れにくいという利点を有している。 By the way, a molded article such as a shaft of a writing instrument is generally molded mainly using a plastic material (for example, polypropylene resin) or an inorganic material (for example, sepiolite), and a plastic material is an inorganic material. It has the advantage of being hard to break compared to.

しかし、その成型品に炭素粉を含ませる場合、炭素粉とプラスチック材料の比重の違いにより、約２０重量％以上の炭素粉を混合させることは極めて難しい。また、約２０重量％未満の炭素粉を混合させて成型するときでも、成型機において炭素粉とプラスチック材料のための射出ノズルが別々に必要であった。 However, when carbon powder is included in the molded product, it is extremely difficult to mix about 20% by weight or more of carbon powder due to the difference in specific gravity between the carbon powder and the plastic material. Even when carbon powder of less than about 20% by weight is mixed and molded, the injection nozzle for the carbon powder and the plastic material is separately required in the molding machine.

また、筆記作業中の使用者を心地良くする（リラックスさせる）ための工夫として、アロマエキスなどの芳香物質をプラスチック材の成型品に含ませることも極めて難しい。 In addition, it is extremely difficult to include an aromatic substance such as an aroma extract in a molded product of a plastic material as a device to make the user during writing work comfortable (relax).

以下、本発明を実施するための最良の形態を図面を参照しながら説明する。図１は本発明の望ましい実施形態に係る筆記具１を示すものであり、（ａ）は側面断面図、（ｂ）は（ａ）のＡ−Ａ線に沿った断面図である。筆記具１はボールペンであり、外郭を形成する略筒状の軸体２と、軸体２の内側に設けられる棒状の芯体３と、軸体２の後端に嵌着される後端栓４と、を有する。 The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 shows a writing instrument 1 according to a preferred embodiment of the present invention, in which (a) is a side sectional view and (b) is a sectional view taken along line AA in (a). The writing instrument 1 is a ballpoint pen, and includes a substantially cylindrical shaft body 2 that forms an outer shell, a rod-shaped core body 3 provided inside the shaft body 2, and a rear end plug 4 that is fitted to the rear end of the shaft body 2. And having.

軸体２は、円筒部２ａと、円筒部２ａの前端に嵌着又は螺着されるペン先ホルダ部２ｂと、円筒部２ａの外面におけるペン先ホルダ部２ｂ側に寄った位置であって指が接触する部分に設けられたグリップ部２ｃと、から成っている。円筒部２ａは、主たる材料が紙材の成型品であり、これに炭素粉が抄き込まれている。円筒部２ａは、水に溶かした紙材に炭素粉を添加した後、脱水して圧縮及び成型することにより製造することができる。この紙材で形成された円筒部２ａは、紙材の密度が高いので使用する上で十分に硬く、その上、無機質材（例えば、セピオライト）のものに比べて割れにくい。また、ペン先ホルダ部２ｂは金属材製である。なお、円筒部２ａとペン先ホルダ部２ｂとを、炭素粉が抄き込まれた紙材で一体に形成することも可能である。 The shaft body 2 includes a cylindrical portion 2a, a pen tip holder portion 2b fitted or screwed to the front end of the cylindrical portion 2a, and a position close to the pen tip holder portion 2b side on the outer surface of the cylindrical portion 2a. The grip part 2c provided in the part which contacts. The cylindrical portion 2a is a molded product of a paper material as a main material, and carbon powder is incorporated into this. The cylindrical portion 2a can be manufactured by adding carbon powder to a paper material dissolved in water and then dehydrating and compressing and molding. The cylindrical portion 2a formed of this paper material is sufficiently hard to use because of the high density of the paper material, and moreover is hard to crack compared to that of an inorganic material (for example, sepiolite). The nib holder 2b is made of a metal material. It is also possible to integrally form the cylindrical portion 2a and the pen tip holder portion 2b with a paper material in which carbon powder is engraved.

炭素粉は、木炭又は竹炭等の炭化物、黒鉛などの粉末である。これらの炭素粉は、光や熱としての外部エネルギを吸収して遠赤外線を放射する。また、炭素粉により円筒部２ａは良好な導電性を有するようになる。炭素粉は、全体に占める割合が大きい程、遠赤外線の放射量及び導電性の点で望ましいが、大きすぎると紙の物理的な強度が低下する。実験の結果、炭素粉は全体の５重量％以上で７０重量％以下の範囲にあるのが望ましく、導電性の点では２０重量％以上であることが更に望ましい。 The carbon powder is a powder such as a charcoal such as charcoal or bamboo charcoal, or graphite. These carbon powders absorb external energy such as light and heat and emit far infrared rays. Moreover, the cylindrical part 2a comes to have favorable electroconductivity by carbon powder. The larger the proportion of carbon powder in the whole, the more desirable in terms of the amount of far-infrared radiation and electrical conductivity, but if it is too large, the physical strength of the paper will decrease. As a result of the experiment, the carbon powder is preferably in the range of 5% by weight or more and 70% by weight or less, and more preferably 20% by weight or more in terms of conductivity.

グリップ部２ｃは、長時間の筆記作業が継続できるように、複数の粒状の軟らかな弾性体（例えば、シリコンゴム）から成っている。複数の弾性体は、所定の間隔（例えば、２ｍｍ程度）で円筒部２ａに固着され、軸体２を握ったときに指の皮膚が円筒部２ａに触れるようにしている。従って、弾性体は、炭素粉を含まなくても良い。このグリップ部２ｃの複数の弾性体は、スクリーン印刷により形成することができる。 The grip portion 2c is composed of a plurality of granular soft elastic bodies (for example, silicon rubber) so that a long writing operation can be continued. The plurality of elastic bodies are fixed to the cylindrical portion 2a at a predetermined interval (for example, about 2 mm) so that the finger skin touches the cylindrical portion 2a when the shaft body 2 is gripped. Therefore, the elastic body may not contain carbon powder. The plurality of elastic bodies of the grip portion 2c can be formed by screen printing.

芯体３は、インク収容部３ａと、インク収容部３ａの前端に固着されるペン先部３ｂと、から成っている。ペン先部３ｂは金属材製である。 The core body 3 includes an ink storage portion 3a and a pen tip portion 3b fixed to the front end of the ink storage portion 3a. The nib portion 3b is made of a metal material.

後端栓４は、軸体２の後端の開口を塞ぎ、また、芯体３の後端を支持する。後端栓４は、紙、金属、プラスチック材料などで形成する。また、紙材製の軸体２に一体的に形成して後端栓４の機能を持たせることも可能である。 The rear end plug 4 closes the opening at the rear end of the shaft body 2 and supports the rear end of the core body 3. The rear end plug 4 is formed of paper, metal, plastic material, or the like. It is also possible to provide the function of the rear end plug 4 by forming it integrally with the paper shaft 2.

この筆記具１を使用すれば、軸体２に抄き込まれた炭素粉により、背景技術において説明した特許文献１の筆記具と同様の効果を得ることができる。すなわち、筆記作業中に、遠赤外線放射により血液循環が促進され、それにより健康増進効果が得られる。また、指又は掌に触れる円筒部２ａは良好な導電性を有し、そして、ペン先ホルダ部２ｂとペン先部３ｂは導電性がある金属材製なので、筆記動作により指又は掌に生じた静電気は筆記具１を介して紙面などに逃げる。静電気が除去されることで手は疲れにくくなり、それにより筆記作業の高能率化も図れる。なお、ペン先ホルダ部２ｂは導電性があるものが望ましいが、筆記作業の途中において円筒部２ａが紙面などに触れることが期待される場合は、それには限られない。また、理由はまだ定かではないが、炭素粉は脳のα波を増加させる効果があることが本願発明者により確認されており、それによっても健康増進効果や筆記作業の高能率化が期待できる。 If this writing instrument 1 is used, the same effect as the writing instrument of Patent Document 1 described in the background art can be obtained by the carbon powder incorporated in the shaft body 2. That is, during the writing operation, blood circulation is promoted by far-infrared radiation, thereby obtaining a health promotion effect. In addition, the cylindrical portion 2a that touches the finger or palm has good conductivity, and the pen tip holder portion 2b and the pen tip portion 3b are made of a conductive metal material. Static electricity escapes to the paper surface through the writing instrument 1. Eliminating static electricity makes your hands less fatigued, which can improve the efficiency of writing. The pen tip holder 2b is preferably conductive, but is not limited to this when the cylindrical portion 2a is expected to touch the paper surface during the writing operation. Moreover, although the reason is not clear yet, it has been confirmed by the present inventor that carbon powder has an effect of increasing the alpha wave of the brain, and it can be expected that the health promotion effect and the efficiency of the writing work are also improved. .

加えて、上述のように、軸体２は、紙材に炭素粉を抄き込むので、容易に所望の量の炭素粉を含ませて製造することができる。 In addition, as described above, the shaft body 2 forms the carbon powder into the paper material, and therefore can be easily manufactured by including a desired amount of the carbon powder.

次に、本発明の望ましい別の実施形態に係る筆記具５を説明する。図２はこの筆記具５を示すものであり、（ａ）は側面断面図、（ｂ）は（ａ）のＢ−Ｂ線に沿った断面図である。筆記具５の芯体３と後端栓４とは、筆記具１と同様である。筆記具５の軸体６は、円筒部６ａとペン先ホルダ部６ｂと巻着シート部６ｄとグリップ部６ｃとから成っている。円筒部６ａは、プラスチック材の成型品であり、炭素粉は含まれていない。ペン先ホルダ部６ｂは、筆記具１と同様である。巻着シート部６ｄは、炭素粉を抄き込んでシート上に形成されたもので、円筒部６ａに巻着されている。グリップ部６ｃは、筆記具１と同様であるが、巻着シート部６ｄに固着されている。巻着シート部６ｄに抄き込まれた炭素粉については筆記具１と同様であるので説明は省略する。 Next, a writing instrument 5 according to another preferred embodiment of the present invention will be described. FIG. 2 shows the writing instrument 5, in which (a) is a side sectional view and (b) is a sectional view taken along line BB in (a). The core 3 and the rear end plug 4 of the writing instrument 5 are the same as the writing instrument 1. The shaft body 6 of the writing instrument 5 includes a cylindrical portion 6a, a pen tip holder portion 6b, a winding sheet portion 6d, and a grip portion 6c. The cylindrical part 6a is a molded product of a plastic material and does not contain carbon powder. The pen tip holder 6 b is the same as the writing instrument 1. The winding sheet portion 6d is formed on a sheet made of carbon powder, and is wound around the cylindrical portion 6a. The grip portion 6c is the same as the writing instrument 1, but is fixed to the winding sheet portion 6d. The carbon powder engraved on the winding sheet portion 6d is the same as that of the writing instrument 1 and will not be described.

この筆記具５の利点は筆記具１と同様である。更に、この筆記具５の利点は、巻着シート部６ｄを炭素粉を抄き込んだ紙材でシート状に別途形成し、それにグリップ部６ｃを固着して別部材として提供し、通常の筆記具に貼り付け巻着するようにすることも可能になることである。 The advantage of the writing instrument 5 is the same as that of the writing instrument 1. Further, the writing instrument 5 has the advantage that the wrapping sheet portion 6d is separately formed into a sheet of paper material made of carbon powder, and the grip portion 6c is fixed thereto and provided as a separate member. It is also possible to attach and wrap.

以上説明した筆記具１、５は、軸体２の少なくとも一部を形成する紙材に、アロマエキスなどの芳香物質が含まれるようにすることができる。具体的には、芳香物質をマイクロカプセルに閉じ込め、マイクロカプセルを紙に抄き込む。時が経つにつれてマイクロカプセルは少しずつ破け、芳香物質が流出して徐々に気化する。そうすると、芳香物質により、筆記作業中の使用者は心地良くなり（リラックスし）、筆記作業の高能率化が図られる。また、マイクロカプセルは少しずつ破けるので、芳香物質の気化は長い期間継続する。炭素粉が炭化物などの多孔質である場合は、マイクロカプセルから流出した芳香物質が炭素粉の多くの孔に蓄えられるので、芳香物質の気化は更に長い期間継続する。 In the writing instruments 1 and 5 described above, the paper material forming at least a part of the shaft body 2 can contain an aromatic substance such as an aroma extract. Specifically, an aromatic substance is confined in a microcapsule, and the microcapsule is formed on paper. As time passes, the microcapsules break little by little, and the fragrance material flows out and gradually vaporizes. Then, the user during writing work becomes comfortable (relaxed) by the aromatic substance, and the efficiency of writing work is improved. Moreover, since the microcapsules are broken little by little, the vaporization of the aromatic substance continues for a long period. In the case where the carbon powder is porous such as carbide, the aromatic substance flowing out from the microcapsule is stored in many pores of the carbon powder, so that the evaporation of the aromatic substance continues for a longer period.

また、上記グリップ部２ｃは、特許文献１に記載された炭素粉を含んだ筆記用リングに置き換えることも可能である。但し、シリコンゴムなどの弾性体は炭素粉を含むと硬くなるので、グリップ部２ｃは握りやすさの面において利点がある。また、コストを削減するためには、握りにくくはなるが、グリップ部２ｃを省略することも可能である。 Further, the grip portion 2c can be replaced with a writing ring containing carbon powder described in Patent Document 1. However, since an elastic body such as silicon rubber becomes hard when it contains carbon powder, the grip portion 2c is advantageous in terms of ease of gripping. Moreover, in order to reduce cost, although it becomes difficult to grasp, the grip part 2c can also be abbreviate | omitted.

以上、本発明の望ましい実施形態に係る筆記具について説明したが、本発明は、実施形態に記載したものに限られることなく、特許請求の範囲に記載した事項の範囲内でのさまざまな設計変更が可能である。例えば、実施形態に記載した筆記具はボールペンであるが、シャープペンシル、万年筆、サインペンなどの他の筆記具に本発明が適用できるのは勿論である。シャープペンシルに適用される場合は、インク収容部３ａは黒鉛芯の収容部に読み替えられる。また、実施形態に記載した形状や構造に限らず、さまざまに変形できることも勿論である。例えば、円形の円筒部２ａ、６ａを多角形（例えば６角形）の多角筒部とすることもできる。 As mentioned above, although the writing instrument which concerns on desirable embodiment of this invention was demonstrated, this invention is not restricted to what was described in embodiment, Various design changes within the range of the matter described in the claim are carried out. Is possible. For example, although the writing instrument described in the embodiment is a ballpoint pen, it is needless to say that the present invention can be applied to other writing instruments such as a mechanical pencil, a fountain pen, and a sign pen. When applied to a mechanical pencil, the ink container 3a is replaced with a graphite core container. Of course, the present invention is not limited to the shapes and structures described in the embodiments, and various modifications can be made. For example, the circular cylindrical portions 2a and 6a may be polygonal (for example, hexagonal) polygonal cylindrical portions.
