| abstract | (57) [Summary] [Purpose] The type of a ball-point pen writing body can be seen from the outside of a barrel, and the tip ball and the tip ball can be held when each writing tip protrudes and disappears from the tip end of the tip. It is possible to solve the problem that the holding portion comes into contact with the tapered inner surface of the mouth portion, and the inner surface is stained with ink to deteriorate the appearance. [Constitution] A plurality of ballpoint pens such as ballpoint pen writing bodies filled with a water-based ink having a so-called shear-thinning viscosity or a low-viscosity oil-based ink, the viscosity of which is reduced due to the rotation of a tip ball caused by writing in an ink storage section. In a dual-type writing implement that has a cursive body mounted inside the barrel and allows each writing tip to selectively emerge from the tip of the tip of the tip of the barrel, the barrel is A tip portion formed to be tapered toward the tip is provided on the front side, and a see-through window portion facing the ballpoint pen writing body is provided on the side surface of the barrel, and at least the entire periphery of the tip portion is opaque. It is provided. |
