PROBLEM TO BE SOLVED: To provide a sheet processing device capable of decreasing a loading amount because a bent sheet bundle opens at loading, and, bent-loop pressurizing it during movement of the sheet.SOLUTION: A sheet processing device includes a relay roller 48 for transporting a bent sheet having been bent to cause a loop, a presser roller 70 for pressurizing the bent sheet along a loop thickness direction, a device frame 55 arranged in a plurality of lines for attachment so that an interval along mutual line direction of the presser roller 70 becomes narrower stepwise, and a gripper member 51 which makes the bent loop pass along a direction in which an interval of the presser rollers 70 in the plurality of lines becomes narrower stepwise, so that, the gripper member 51 transports the bent sheet in a direction across the sheet transportation direction by the relay roller 48, and pressurizes the bent loop stepwise by the presser roller 70 in the transportation process.SELECTED DRAWING: Figure 21 |
