摘要： A post-processing device (200) includes a circulation conveyance path, a zeroth conveyer (R0), and a controller (50). The circulation conveyance path includes a first conveyance path (W1), a second conveyance path (W2), a third conveyance path (W3), a first conveyer (R1), a second conveyer (R2), and a third conveyer (R3). The first and second conveyers convey a preceding sheet (P1) along the first and second conveyance paths. The third conveyer conveys it from the third conveyance path to the first conveyance path. The zeroth conveyer conveys a following sheet (P2) toward the first conveyer. The controller controls the third conveyer to stop the preceding sheet, subsequently controls the zeroth conveyer and the third conveyer to overlay the preceding sheet with the following sheet to form a sheet bundle (Q) having a shift amount (G) between a leading edges of the preceding sheet and the following sheet and strike the leading edges of the preceding sheet and the following sheet against the first conveyer.

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 first guide plate and a second guide plate facing with a given space in a thickness direction and having second and third openings, a sheet conveyance passage between the first and second guide plates, and a sheet conveyor including a drive source, a drive roller, a first driven roller, and a second driven roller. The drive roller protrudes from the first guide plate toward the sheet conveyance passage through the first opening. The first driven roller faces the drive roller and protrudes from the second guide plate toward the sheet conveyance passage through the second opening. The second driven roller protrudes from the second guide plate toward the sheet conveyance passage through the third opening. The second driven roller is disposed at a position shifted from the drive roller in a width direction orthogonal to the sheet conveyance direction and the thickness direction.

摘要： A sheet processing apparatus includes a sheet conveyance passage, a sheet circulation passage, a first conveyor, a second conveyor, a third conveyor, and circuitry. In the sheet circulation passage, a sheet is circulated to be overlaid with a following sheet in the sheet conveyance passage. The circuitry circulates the sheet in the sheet circulation passage to overlay the sheet with the following sheet conveyed after the sheet in the first sheet conveyance passage, at an upstream position of the first sheet conveyance passage, and adjusts a sheet conveyance speed of the third conveyor to circulate the sheet, based on a reduction amount that is obtained when a preceding amount of a leading end of the following sheet with respect to a leading end of the sheet is reduced while the following sheet is temporarily stopped due to a temporary stop of the first conveyor.

摘要： A binding apparatus to bind sheets includes a binding device, a non-volatile memory, and control circuitry. The binding device is configured to bind a plurality of stacked sheets with a binding member. The non-volatile memory is configured to store a quantity of binding members in the binding device. The control circuitry is configured to control operation of the binding device. The control circuitry outputs an alert when the quantity of binding members stored in the non-volatile memory is equal to or less than a first predetermined value and cancels the alert when the quantity of binding members is equal to or less than a second predetermined value.
