Description
【考案の詳細な説明】 「産業上の利用分野」 本案は、改良された鉛筆に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to an improved pencil.
「従来の技術」 従来、使用され短くなった鉛筆を捨てる無駄を回避し、
握り易さを保持するため、該鉛筆の根本を着脱自在に把
持できるペン状キャップが開発されている。"Conventional technology" Avoid the waste of throwing away the pencils that have been used and shortened,
In order to maintain the ease of gripping, a pen-like cap has been developed that can detachably hold the base of the pencil.
しかしながら、該キャップを利用しても、該キャップの
把持部に係合するだけの軸木の長さを要するし、鉛筆は
その先端を円錐状に削り芯を突出させるものであるの
で、該軸木よりも長い芯が無駄となっていた。また、該
キャップは、それを使用するといかにも倹約家であるか
の如く見られるので、特に若い学生諸君には敬遠されが
ちであるという問題がある。さらに、該キャップを常備
しておくことはめんどうであるので、結局使用可能な芯
を有する鉛筆が捨てられてしまうという傾向があった。However, even if the cap is used, the length of the shaft is only enough to engage with the grip portion of the cap, and the pencil has a conical tip to project the core. A core longer than a tree was wasted. There is also a problem that the cap tends to be shunned especially by young students because it looks like a thrift when it is used. Furthermore, since it is troublesome to keep the cap in stock, there is a tendency that the pencil having a usable lead is thrown away after all.
「考案が解決しようとする課題」 本案は、格別の道具を準備しなくとも、芯を無駄なくか
つ体裁良く使い切ることができる鉛筆であって、芯がな
くなるまで握り易さ、書き易さが良好である鉛筆を提供
することを目的とするものである。"Problems to be solved by the invention" This is a pencil that can be used up without waste and with good appearance without preparing special tools. It is easy to grasp and easy to write until the core disappears. The purpose is to provide a pencil.
「課題を解決するための手段」 上記目的を達成するため、本案は 芯を該芯よりも長い軸木で該芯の一端部から長手方向に
被覆し、該芯の他端部分の軸木の外周面に着色し、該着
色部と前記軸木の外周面とを該着色部と色彩が異なる塗
料で塗装してなる鉛筆 によって構成される。[Means for Solving the Problems] In order to achieve the above object, the present invention proposes that a core is covered with a shaft longer than the core in the longitudinal direction from one end of the core, and the other end of the core is covered with the shaft. The pencil is formed by coloring the outer peripheral surface and coating the colored portion and the outer peripheral surface of the shaft with a paint having a color different from that of the colored portion.

る。[Operation] Therefore, the user scrapes one end of the pencil on the side where the core 1 is covered with the stem 2, and performs writing, drawing and the like. Then, when the pencil is shaved until the core 1 is slightly left, the colored portion 3 having a color different from that of the paint 4 appears, so that the user can easily know that there is almost no remaining core 1, and the core 1 The inner end 1b can be used up. Further, the shaft 2 is provided with an appropriate length such that it can be easily grasped until the core 1 is used up.

ても良い。"Embodiment" FIGS. 1 to 4 show an embodiment of the present invention. According to this example, a core 1 in the shape of a black round bar is covered with a stem 2 longer than the core 1 and having a hexagonal cross section in the longitudinal direction from one end 1a of the core 1. For this coating, a synthetic resin adhesive was applied to a thin plate (not shown) in which several grooves for inserting the core 1 were juxtaposed, the core 1 was put in the groove, and the thin plate was polymerized with another thin plate and tightened and dried. After that, it is preferable to cut the edge of the plate. And the other end of the core 1
The outer peripheral surface of the shaft 2 is colored 3 with red ink or dye at the portion corresponding to 1b. Further, the colored portion 3 and the outer peripheral surface of the shaft 2 are coated with a green paint 4. An enamel lacquer or the like is preferably used as the paint 4 described above.
It does not matter if it is not a single color, and it may be transparent.

際の切削面である。5 and 6 show another embodiment of the present invention. In this example, a blue core 1 and a red core 1 are arranged on both ends of a shaft 2 having a circular cross section on the common center axis line. Alternatively, one core 1 may be 3H for precision drafting, and the other core 1 may be 2B for shorthand. For example, the hardness may be different. The rest is the same as in the above embodiment. The reference numeral 5 in the drawing is a cutting surface when the pencil is cut down to the colored portion 3.
