Pulleys 29 a , 29 b are provided on both ends of the driven roller 28 as separate components from the driven roller 28 , and on both edges in the width direction of the transfer belt 24 , ribs 24 a , 24 b that can be engaged with the outer sides in the axial direction of the pulleys 29 a , 29 b are provided. If the transfer belt 24 becomes inclined to the left side during movement, the rib 24 a on the right edge of the transfer belt 24 will be restricted by the outer side in the axial direction of the pulley 29 a provided on the right side end of the driven roller 28 , thereby correcting meandering to the left at the position of the driven roller 28.
