<P>PROBLEM TO BE SOLVED: To provide a belt drive device that lays an endless belt across a plurality of rollers, and suppresses meander of the endless belt to ensure stable rotation of the belt. <P>SOLUTION: A belt drive device lays an endless belt 21 between a drive roller 23 and a driven roller 22, and inserts a rotation shaft 24 of the driven roller 22 into a slot 251 that is formed on a movement regulating plate 25. The belt drive device then energizes the driven roller 22 outward with a press spring S to apply tensile force to the endless belt 21, and in such a state that the endless belt 21 is stretched, regulates the amount of movement of the driven roller 22 with the slot 251. <P>COPYRIGHT: (C)2012,JPO&INPIT |
