<P>PROBLEM TO BE SOLVED: To provide a belt conveyance device which has a good responsiveness and comprises a belt deviation resolution mechanism reducing load on a belt in a simpler constitution. <P>SOLUTION: A belt conveyance device comprises ribs 12a and 12b provided in the end parts of the inner peripheral surface of a belt 1 in the width direction, and rolls 16a and 16b provided on a rotation center of a tension roller 4 and on the end parts of the tension roller 4 in the width direction, and independently rotatable with respect to the tension roller 4. When the belt 1 deviates in one direction on the tension roller 4, one of the rolls 16a and 16b rotates by receiving the torque of the belt 1 from the rib 12a or 12b, and the torque of the rolls 16a or 16b inclines the rotation center of the tension roller 4 with respect to the rotation center of the drive roller 2 to move the belt 1 in the opposite direction of the deviation direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
