<P>PROBLEM TO BE SOLVED: To solve such a problem that a pen cannot be used for writing due to clogging of a pen point (felt tip) or for other reasons and enable normal writing by utilizing the effect of pressurization. <P>SOLUTION: A pressurizing type writing implement has a felt tip of a felt-tip pen, a marker or the like at the tip and is provided with ink in an ink holding part in the rear and a pumping type pressurizing mechanism in the rear of the ink. Herein the felt tip constituted of a hard felt body and a relatively soft enclosing body enclosing the felt body and allowing passage of the ink is fitted in the opening of a tip holder part in the front of a holder tube movablly forward and backward properly, and a valve element allowing passage of the ink is disposed in the rear of the felt tip. When the rear end of the felt tip comes into contact with a valve part allowing passage of the ink of the valve element to make the felt retreat, the valve part is opened so that the ink is allowed to flow from the ink holding part side to the felt tip side. <P>COPYRIGHT: (C)2007,JPO&INPIT |
