PROBLEM TO BE SOLVED: To stably carry a thick sheet and a thin sheet in a belt carrying system divided into a plurality of pieces over the carrying lateral direction, which is applied to a common carrying passage, by regularly keeping the belt tension at a prescribed value over the carrying lateral direction. SOLUTION: In a belt carrying passage, a roller 310 at the tip is regularly energized in a carrying pat direction (arrowed direction A) by a tensile coil spring 314. Accordingly, a plurality of belts 140 arranged in the carrying lateral direction can keep tensions individually, and even if a carrying resistance is generated by any cause in a part of the carrying lateral direction in carrying, the tension of the other position is surely kept so as not to disturb the carrying.
