ン先の製造方法を発明するに至ったのである。In view of the above-mentioned drawbacks, the present invention has been devoted to a method of manufacturing a writing pen nib that has excellent wear resistance, first rigidity, and satisfies ink transport characteristics.The present invention has resulted in a hollow pipe KS having an island bottom. One writing end is formed by drilling 11 or more holes without penetrating the bottom from the inner end surface to the outer end surface, and then grinding the outer peripheral surface of the bottom until the holes are exposed on the surface. He was able to invent a method for manufacturing writing pen nibs.

Drill one or more holes 6 from the inner end face 3 of the bottom part 2 toward the outer end face 4 without penetrating into a hollow pipe l (outer diameter 7 m/m, inner diameter 5 m/m) having a bottom part 2 of m/m. Then, by grinding the outer peripheral surface of the bottom 2 until the hole is exposed on the surface, a chopstick writing nib having the writing end 6 shown in FIG. 2 is obtained.

As a writing pen nib, which is the technical field of the present invention, the hole diameter of the ink passageway is approximately 10 to 200μ, and the depth is 1). It can be seen that it is about 2 to am/m at most.

The melt 1 sublimates, but the molten residue remains on the surface and inside the core and solidifies when cooled, producing so-called "paris". The occurrence of such blemishes causes problems such as tearing of the paper surface, scratches, and uneven line width during one writing process.

る。The manufacturing method of the present invention includes the steps of (1) drilling a hole in a hollow pipe having a bottom without penetrating it from the inner end surface to the outer end surface of the bottom, and then (1) grinding the outer circumferential surface of the hollow pipe to form a writing end. During laser machining, air is blown into the hollow pipe or suctioned from the hollow pipe to remove the melted residue without causing any particles on the writing surface. It is possible to remove the residue remaining in one hole by blowing or suctioning air from the rear open end of the hole.

形状の穴を穿設することができる。In addition, according to the manufacturing method that is a feature of the present invention, by appropriately selecting the thickness of the hollow pipe and further selecting the desired polished shape, numerous types of writing pens from thin to bold can be manufactured. In addition, holes of appropriate shapes can be provided according to the chemical and physical properties of the ink used.

。When assembling the writing nib produced by the manufacturing method of the present invention as a writing instrument, for example, insert the ink guiding member from the rear open end of the hollow nozzle until the tip of the member contacts the inner end surface of the bottom of the hollow pipe. The writing instrument body and the hollow pipe are connected until the writing instrument is inserted and the rear end of the ink guiding member is inserted into the ink storage body or ink cartridge.

This also made carbon copying possible.
