<P>PROBLEM TO BE SOLVED: To provide a multiple writing implement having a plurality of different inside diameter tube bodies which can arbitrarily select their attachment positions. <P>SOLUTION: A fitting member 30 is attached at the rear end of a tube body 4S of a mechanical pencil refill 3S so that the mechanical pencil refill 3S can be connected through the fitting member 30 to the sliders 20 of which the specification is designed to fit ballpoint pen refills 3B, 3R. Thereby, even after the start of use of the multiple writing implement 1, the slider 20 serviceable to connect either of the ballpoint pen refills 3B, 3R and the mechanical pencil refill 3S can be selected, and furthermore, one of the sliders 20 can be arbitrarily selected as the serviceable slider 20, and the attachment positions of the ballpoint pen refills 3B, 3R and the mechanical pencil refill 3S can also be arbitrarily changed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
