ある。Therefore, when the pen tip formed of the elastic body capable of being impregnated with ink is press-fitted and attached to the holder, the elastic body is compressed, and the impregnated amount of ink becomes small. The distribution of ink was poor. Therefore, as a modification of this point, a pen tip is fixed by a pin inserted from the outer peripheral direction of the holder, but there is a drawback that the number of assembling steps is large and the productivity is poor. An object of the present invention is to provide a pen tip attachment structure for a writing instrument that solves the above problems.

軸筒１の前部外側１Ｂに取り付けられる。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. A plurality of ribs 1 extending in the longitudinal direction of a barrel 1 are provided.
Batting 2 which forms A and is impregnated with ink by the rib 1A
To fix. Further, a holder 3 made of metal or resin is attached to the front part of the shaft cylinder 1, and an air hole 3A for adjusting the internal and external atmospheric pressure is formed in the holder 3. A relay core 4 for guiding the ink in the batting 2 by a capillary action is fixed to the rear inner hole 3B of the holder 3, and the rear portion of the relay core 4 is the batting 2 described above.
Is connected to the tip of the. The tubular guide member 5 made of metal is formed thin so that the middle portion is recessed, and the pen tip 6 is inserted into the inner hole 5A of the guide member 5. In this state, the thin portion of the guide member 5 is pressed by punching to push the protrusion 5
B is formed, and the protrusion 5B bites into the pen tip 6 to fix the pen tip 6. Although four protrusions 5B are formed in the illustrated embodiment, the number of protrusions may be two or three. Various materials such as sponge may be used as the material of the pen tip 6 as long as it is an elastic body that can be impregnated with ink. For example, the pore diameter is 10 μ ±
1, urethane foam having an opening ratio of 75% to 80% is considered. The guide member 5 to which the pen tip 6 is fixed is press-fitted and fixed in the front hole 3C of the holder 3, and the rear portion of the pen tip 6 contacts the relay core 4. Since the thick fixing portion 5C of the guide member 5 press-fitted into the holder 3 is press-fitted into the front hole 3C of the holder 3, the guide member 5 is firmly press-fitted and fixed. Therefore, only a part of the pen tip 6 is deformed by the protrusion 5B, and there is no possibility of obstructing the flow of ink in the pen tip 6. Further, a cap 7 that covers the pen tip 6 is attached to the front outer side 1B of the barrel 1.
【０００６】尚、ペン先は、柔らかい方が筆跡は鮮明だ
が、細いものは筆跡時の圧力と抵抗の為変形しやすいの

たりの荷重が下がるため柔らかい方が好ましい。例え
ば、ペン先の外径が４ｍｍ程度のものは比較的固い（ゴ
ム硬度３０〜５０程度）方が好ましい。It should be noted that a soft pen tip has a sharp handwriting, but a thin pen tip is easily deformed due to pressure and resistance at the time of handwriting. In addition, thicker ones are preferable because the load per unit area decreases. For example, a pen having an outer diameter of about 4 mm is preferably relatively hard (rubber hardness of about 30 to 50).
【０００７】更に、ペン先の形状としては、図４に示し

インキが残らずより好ましい。Further, as the shape of the pen tip, as shown in FIG. 4, a penetrating hole 16A may be formed in the center of the pen tip 16. Also in this case, since the pen tip 16 is fixed by the protrusion 5B of the guide member 5, there is no possibility that the through hole 16A is compressed and closed. Therefore, even if the ink impregnated in the pen tip 16 oozes out because the pen tip 16 lands on the paper surface and is compressed, it is absorbed in the through hole 16A when the pen tip 16 is separated from the paper surface, and It is more preferable because excessive ink does not remain.
【０００８】尚、ペン先の先端形状は平坦に限らず先端
部分に丸みを持たせた形状にすることも可能である。The tip shape of the pen tip is not limited to a flat shape, and the tip portion may have a rounded shape.

Of course, it can be used for a writing instrument in which ink is stored in a liquid state in a barrel.

である。The writing instrument of the present invention is particularly excellent as a writing instrument for a plotter, especially when it is attached to a plotter to draw or paint a thick line, even if high speed writing is performed by the plotter, the ink can sufficiently penetrate into the pen tip. It can be effective.

ものである。As described above, the present invention is characterized in that the pen tip is fixed by the projection formed by the pressing deformation of the guide member, and the guide member is fixed to the holder. Therefore, the pen tip formed of the elastic body that can be impregnated with ink is not compressed for fixing, and the ink can sufficiently penetrate into the pen tip and the pen tip can be fixed very easily. It can be done.
