<P>PROBLEM TO BE SOLVED: To stably hold a large number of sheets while suppressing manufacturing cost. <P>SOLUTION: This sheet holding tool includes a base plate 1, a holding plate 2, and a plate 3. A metallic plate 7 fitted into a back face side of the holding plate 2 is smaller than a magnet 4 fitted into a back face side of the base plate 1. The center of the metallic plate 7 is disposed at a position deviated from the center of the magnet 4. The centers of the magnet 4 and the metallic plate 7 are deviated from each other intentionally, to obtain high attraction force without using the large magnet 4. The manufacturing cost is suppressed, and a larger number of sheets can be stably held due to weight reduction caused by reducing the size of the metallic plate 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
