2. Description of the Related Art Conventionally, there has been no need to use a printing material formed of a porous stamping material having an infinite number of continuous pores such as sponge rubber so as to absorb ink, and to attach it to vermilion or the like every time it is used. A writing implement with a seal is known in which a seal is attached to the rear end of a shaft. However, if the writing surface of the seal is exposed, this type of writing instrument with a seal may cause scratches on the printing surface, adhere to dust, or dry the ink. Therefore, not only is it troublesome to attach and detach the cap, but also there is a problem that the cap is lost, and there is a problem that the hand is erroneously stained at the time of attachment and detachment. Hard seals, such as ivory and other seal materials using vermilion, are rarely scratched, but have the problem of becoming dirty, adhering dust, and losing the cap.

Further, conventionally known oil-based ballpoint pens have a high viscosity, and a small amount of ink flows out when the tip ball rotates during writing. In addition, there are problems such as unevenness, unevenness of writing lines, low density, and high writing pressure. In addition, as an improvement of the conventional oil-based ballpoint pen, a relatively low-viscosity ink is used. Are known. However, since this ink has a drawback that the ink easily dries, a cap for sealing the writing tip is required. Therefore, a low-viscosity oil-based ink with excellent drying resistance is conceivable. However, the amount of the ink flowing out is also large, and in order to increase the writing life, the diameter of the ink storage tube is increased to increase the amount of ink loaded. . The same applies to the above-mentioned water-based ink. However, since the viscosity of the ink is smaller than that of the conventional oil-based ballpoint pen ink, the flow resistance to the ink storage tube is small. Therefore, ink leakage (ink flows backward at the rear end of the ink storage tube) easily occurs due to the weight and impact of the ink. For this purpose, a grease-like follower is provided at the rear end of the ink, which normally moves following the consumption of the ink during writing, but suppresses the backflow of the ink against its own weight or impact. However, even when the follower is provided, if the ink on the back side of the tip ball runs out when writing upward, there is a danger that the ink or the head will be added directly, causing a remarkable backflow and soiling the hands and clothes. In addition, since the viscosity of the ink is low and the amount of outflow is large, if the tip side faces downward and a gap is formed between the tip ball and the tip holding portion, the ink may bleed (direct current). Further, there is a problem that the ink on the back surface of the tip ball tends to flow backward after upward writing or after an impact such as knocking or dropping, so that writing blur occurs.

In this case, it is more convenient in design to form the inner cap and the shaft cylinder as separate members. The reason why the pen tip is closely fitted to the inner cap in the embodiment is that the writing implement with a seal of the present invention can share a pen shaft such as a sign pen in addition to a ball-point pen, thereby expanding the options for the user. In addition, the notch 3 of the tail plug from the tip end of the tip shaft 33 through the ventilation groove 6 of the joint.
An air passage necessary for writing is formed through 9 to the rear end hole of the ink storage tube 19.
