<P>PROBLEM TO BE SOLVED: To provide an eraser device wherein a plurality of separated rectangular erasers are combined, and thereby new angles are provided one after another. <P>SOLUTION: Erasers are coupled such that the plurality of separated rectangular erasers are stored in a case made of a light-weight and heavy-duty material such as paper and synthetic resin, and they are easily pulled out, and are turned in some other direction, or upside down. As shown in Fig.4, if there are three rectangular erasers, twenty-four angles are made to easily appear one after another so that a fine part is accurately and easily erased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
