摘要： A post-processing apparatus includes a first conveyor, a second conveyor, a third conveyor, and a conveyance passage corrector. The first conveyor conveys a sheet conveyed along a first conveyance passage downstream from the first conveyor. The second conveyor conveys the sheet along a second conveyance passage. The third conveyor conveys the sheet along a third conveyance passage. The conveyance passage corrector includes a retracting mechanism to retract from a joining position at which the third conveyance passage joins to the first conveyance passage and turns a conveyance direction of the sheet toward the first conveyor when the sheet enters from the third conveyance passage to the first conveyance passage.

摘要： A sheet processing device includes a first conveyance passage, a first conveyor, a second conveyor, a folder, a second conveyance passage, and circuitry. The circuitry is configured to (1) cause the first conveyor and the second conveyor to convey the sheet nipping the sheet to warp the sheet between the first conveyor and the second conveyor, (2) guide the warped sheet to form a first fold on the sheet by the folder and circulate the sheet to the first conveyance passage, (3) cause the first conveyor and the second conveyor to convey the sheet while nipping the sheet again to warp the sheet between the first conveyor and the second conveyor, (4) guide the warped sheet to form a second fold on the sheet by the folder, and (5) cause the second conveyor to convey the sheet with the first fold and the second fold.

摘要： A sheet processing apparatus includes a conveyance roller pair that rotates in a certain direction to convey a sheet, a first normal-reverse rotation roller pair that is capable of rotating in a normal direction and a reverse direction and rotates to convey the sheet, a first driver that drives the first normal-reverse rotation roller pair to rotate, and a first driving force transmitter that transmits a driving force of the first driver for rotating the first normal-reverse rotation roller pair in a first specific direction to the conveyance roller pair so as to rotate the conveyance roller pair in the certain direction, and blocks a driving force of the first driver for rotating the first normal-reverse rotation roller pair in the direction opposite to the first specific direction from being transmitted to the conveyance roller pair.
