Abstract

See full text

A penpoint assembly includes a penpoint which is made of a metal plate cut off at both side edges to form a taper toward the writing tip. A slit is provided extending from the front end of the writing tip to the vicinity of the rear end of the writing tip along the center line of the penpoint. The penpoint is bent at the writing tip to form small bent projections at both sides of the slit, the bent portion surrounding a small space. An ink guide core extends under the slit and communicates at the tapered portion of the ink guide core with the slit. A support member supports the ink guide core and penpoint. A writing instrument includes the penpoint assembly, the support member being integrally formed with an ink flow regulating portion, so that ink in an ink storage member in the rear portion of a penholder is guided to the writing tip through the ink guide core.
