Conical nib, method of manufacture of the same, and ceramic composite conical nib

摘要

A highly durable conical nib is provided which also realizes a significant improvement in a nib productivity and a significant cost reduction. The conical nib comprises: a plurality of separated combtooth pieces (2) being able to converge progressively toward front ends thereof and combine to form a virtually conical shape and that the front ends thereof combine to form a virtually spherical shape; a holding member (3) capable of arranging the combtooth pieces along a circumference; and a converging member (4) capable of converging these combtooth pieces; wherein the plurality of separated combtooth pieces are assembled by the holding member and the converging member, both separate from the combtooth pieces, into a conical nib having a writing tip at the front end thereof and an ink feeding path between each combtooth piece. To enhance durability, this nib may be constructed of a base portion and a plurality of combtooth pieces and hemisphere-divided portions wherein each of the combtooth pieces is divided into a front piece and a rear piece and the front piece is formed from a ceramic material and the rear piece from a flexible material such as synthetic resin.
