<P>PROBLEM TO BE SOLVED: To provide a convenient pressurized type ball-point pen which enables the conversion of a written line by converting the pressure setting of a pressure mechanism using pumping. <P>SOLUTION: In this pressurized type ball-point pen, a front end is provided with a ball-point pen tip; an ink storage part in the rear is filled with the ink; a rear end of the ink is filled with a follower following the ink; and the pumping type pressure mechanism is provided in the rear of the follower. Air is fed in by the pumping action of the pressure mechanism so that a rear end of the follower can be pressurized, and applied pressure can be converted. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
