<P>PROBLEM TO BE SOLVED: To provide an erasing implement capable of quickly and surely erasing a heat discoloring image or handwriting on paper, sufficiently avoiding the damage of a friction body and paper and sufficiently maintaining the coloring state of the heat discoloring image or handwriting on the paper at an ordinary temperature, and a writing implement set. <P>SOLUTION: The erasing implement 1 includes a body 11, a motor 13 held in the body 11, and the friction body 12 made of a resin material, and mounted to a rotating shaft 13a of the motor 13 and projected outside from the distal end of the body 11. The friction body 12 rotated by the rotation of the motor 13 directly rubs against the heat discoloring image or handwriting formed on the paper, and the image or handwriting is discolored by frictional force generated in rubbing. A friction coefficient of the friction body 12 and paper is 0.1-1.0, and the rotating speed of the friction body 12 when the friction body rubs against the heat discoloring image or handwriting on the paper is 500-20,000 rpm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
