不利欠点がある。 A felt-tip pen with a thin nib (for example, a thin nib with a diameter of 1 m/m or less) is well known, but this well-known product has the following disadvantages.

かなりの熟練を要するなどの不利がある。 First, regardless of the pen nib mounting structure, the ink stored in the barrel (most well-known products have an ink absorber impregnated with ink and stored in the barrel) is consumed. Before long, the thin nib of the pen wears out, making it difficult to use, and the entire pen has to be thrown away, even though it doesn't last long.As a result, resource and energy conservation is being strongly promoted. Nowadays, this is a significant disadvantage. (When the applicant conducted an experiment on the ink consumption using the above-mentioned well-known product, it was found that after writing for 1000 meters with a fine nib of 0.8m/m diameter, the nib wore out, but the ink consumption was only 35%. (It was found that a considerable amount of ink remained at the front and back.) Secondly, products in which the pen tip is fixed to a thin tube and the thin tube is fixed to a holder are widely known; When constructing a pen, a major problem is the means of fixing the pen tip to the thin tube. For example, it is well known that a part of the thin tube is caulked to fix the pen tip, but due to the caulking structure, a part of the pen tip deforms and the internal ink passage becomes narrow.
This can cause blockages and obstruct the smooth flow of ink. In addition to this structure, a structure in which the entire circumference of the thin tube into which the pen tip is inserted is narrowed down to a small diameter, the pen tip bites into the entire circumference of the pen tip, and the pen tip is fixed to the thin tube has also been proposed and is well known. However, even with this configuration, the pen tip deforms and narrows or blocks the internal ink passage, impeding the smooth flow of ink and causing ink to run out when writing quickly or continuously. In addition, there is a risk that the peripheral wall of the pen tip may be destroyed during the process of narrowing the pen tip to a small diameter, and this process requires considerable skill.

従つて、周知品は解決を必要とする種々の課題

Equipped with a press-fitting tool that allows the pen tip attachment tube to be inserted and removed from the holder.
It is characterized by a structure that allows the user to easily replace the pen nib alone or the pen nib mounting capillary tube with a pen nib with a new one at any time as necessary, thus eliminating the disadvantages of the well-known products, and
Our aim is to provide useful writing instruments that are responsive to the era of resource and energy conservation.
