Summary:A pen core for a writing instrument, particularly, for use in a recorder in which writing must be continuously carried out over long periods using a relatively small ink supply. The instrument has an ink conducting core for conducting ink to a writing member, and a barrel with an ink reservoir, the barrel being fitted on the outer wall of the pen core body. An annular groove in the form of a single continuous passageway is formed in the outer wall of the pen core body, the annular groove having a front end connected to an ink sucking groove, which is in turn communicated with the ink conducting core. An air passageway having a front end communicated with an air hole and a rear end communicated with the rear end of the annular groove is formed in the outer wall of the pen core body in such a manner that the air passageway does not cross the annular groove.
