【従来の技術】[Prior art]

従来、おもり部材がインキ流通孔内に軸方向可動に挿入されてなるタイプの細管式筆記具において、針体とおもり部材は、接着や溶着、或いは圧着や嵌着等によって固着される構成が一般的である。 Conventionally, in a capillary-type writing instrument of a type in which a weight member is axially movably inserted into an ink circulation hole, the needle body and the weight member are fixed to each other by adhesion, welding, crimping, fitting, or the like. It is common.

【考案が解決しようとする課題】[Problems to be solved by the device]

前記従来の細管式筆記具において、一般におもり部材はインキの誘導作用を備え、その外部又は内部をインキが流れるため、針体とおもり部材を固着させる構成では、固着個所に接着剤等のはみ出しによる余分の固まりを生じさせたり、又固着個所に空気を残留させがちであり、筆記先端部へのスムーズなインキ導出の妨げとなっていた。その上、針体は細管からわずかに突出するよう組付けられねばならず、おもり部材と針体の固着に対して慎重な作業が要求された。 In the conventional thin-tube writing instrument, the weight member generally has an ink guiding action, and the ink flows through the outside or inside of the writing device.Therefore, when the needle body and the weight member are fixed to each other, the adhesive or the like does not stick out to the fixing point. These tended to cause extra lumps due to the ink, and tended to leave air at the fixed points, which hindered the smooth outflow of ink to the writing tip. Moreover, the needle body had to be assembled so as to slightly project from the thin tube, and careful work was required for fixing the weight member and the needle body.

【０００４】本考案は前記した従来の問題点を解決しようとするものであって、精密で手間のかかる針体とおもり部材の固着作業を必要とせずに針体出長さの寸法管理ができ、且つ性能面においてもスムーズなインキ流出を可能とする細管式筆記具を提供しようとするものである。The present invention is intended to solve the above-mentioned conventional problems, and it is possible to perform dimensional control of the needle body protruding length without requiring the precise and time-consuming work of fixing the needle body and the weight member. In addition, it aims to provide a thin-tube writing instrument that allows smooth ink outflow in terms of performance.

【作用】[Action]

筆記状態（通常筆記先端は下向き状態）では、少なくともおもり部材５は、バネ体７或いはその自重によって前方へ付勢され、針体６の当接部６１と当接が可能となり、針体６の前進後退を制御する。 In the writing state (usually, the tip of the writing is facing downward), at least the weight member 5 is biased forward by the vane body 7 or its own weight, and can come into contact with the abutting portion 61 of the needle body 6, whereby the needle body Control forward and backward movement of 6.

【００１３】インキ流通孔４１内において、おもり部材５は、インキ誘導作用を備えて、その外部又は内部をインキが流れる。針体６とおもり部材５は非固着状態であるため、接着剤の固まり等のインキの導出の障害を形成させることがない。その上、筆記時、当接部６１に空気が残留した場合でも、針体６の径方向の微動によって、空気を当接部６１より後方へ移動させ、スムーズなインキ流出を可能とする。In the ink flow hole 41, the weight member 5 has an ink guiding function, and the ink flows outside or inside thereof. Since the needle body 6 and the weight member 5 are in a non-fixed state, there is no possibility of forming an obstacle such as a lump of the adhesive agent for leading out the ink. In addition, even when air remains in the contact portion 61 during writing, the fine movement of the needle body 6 in the radial direction causes the air to move rearward from the contact portion 61, enabling smooth ink outflow.

【考案の効果】[Effect of device]

本考案細管式筆記具は、針体とおもり部材が固着されていないため、精密で手間のかかる針体とおもり部材の固着作業を必要とせずに針体の突出長さの寸法管理ができ、固着時の接着剤の固まりによってインキ流通に障害を与えることがなく、更に、筆記時の針体の微動によっておもり部材と針体の当接個所の空気の残留を防ぐことができる。よって、インキ流通孔から細管へのインキ流通がスムーズとなり、プロッター等の高速筆記においても、筆跡のかすれや途切れを発生させない細管式筆記具を提供できる。 In the thin-tube writing instrument of the present invention, since the needle body and the weight member are not fixed to each other, the dimension of the protruding length of the needle body can be controlled without requiring a precise and time-consuming work of fixing the needle body and the weight member. In addition, the solidification of the adhesive at the time of fixation does not hinder the ink flow, and the slight movement of the needle body at the time of writing can prevent air from remaining at the contact point between the weight member and the needle body. Therefore, the ink can be smoothly distributed from the ink circulation hole to the thin tube, and it is possible to provide a thin tube-type writing instrument that does not cause fading or discontinuity of handwriting even in high-speed writing such as with a plotter.
