  • Patent number: 8814157
    Abstract: A sheet processing apparatus includes a sheet stacking unit where sheets to be processed are stacked, a regulating member, a sheet waiting unit, a first moving unit, a second moving unit, and a control unit. The regulating member abuts on one edge of sheets conveyed to the sheet stacking unit. The sheet waiting unit keeps sheets waiting, stacks the waiting sheets displaced sequentially, and then conveys the sheets to the sheet stacking unit. The first moving unit sequentially moves the conveyed sheets, starting from a lowermost sheet, to be abutted against the regulating member. The second moving unit moves the conveyed sheets to the first moving unit. The control unit controls a moving speed of the second moving unit so that a next sheet does not reach the first moving unit until the sheet moved by the first moving unit is abutted against the regulating member.

  • Patent number: 8794617
    Abstract: A finisher is provided with a transport paddle and a control portion. The transport paddle freely moves to a first position where the transport paddle is on standby while protruding above a lower stack tray, a second position where the transport paddle sandwiches the sheet in between and, at the same time, is transported to abut the sheet against the abutment portion, and a third position where the transport paddle retracts in a finisher body 400. The control portion makes the transport paddle be on standby at the first position at least at the start of a job, moves the transport paddle between the first position and the second position for each discharge of the sheet by the bundle discharge roller pair, and moves the transport paddle to the third position after termination of the alignment processing for a last sheet of the job.

  • Patent number: 8770571
    Abstract: A sheet stacking apparatus includes an alignment unit configured to align a sheet stacked on a stacking tray in a width direction which is orthogonal to a direction in which the sheet is discharged. The alignment unit includes first and second alignment members configured to move in the width direction. The first and second alignment members come into contact with side ends in the width direction of the sheet stacked on the stacking tray to align the sheet. When a second sheet of a different length in the width direction from that of a first sheet is stacked while shifted in the width direction on the first sheet which is already stacked on the stacking tray, the sheet stacking apparatus prohibits an alignment operation of the alignment unit on the second sheet.

  • Patent number: 8752819
    Abstract: A sheet processing apparatus that is capable of aligning sheets in a sheet longitudinal direction with high accuracy when bundling the sheets. A conveyance unit conveys a sheet. A stacking unit stacks a plurality of sheets that are conveyed by the conveyance unit. A grasping member performs a grasping operation that grasps the rear end of the sheet surface of the sheets stacked on the stacking unit. A driving unit moves the grasping member. A control unit controls the driving unit so as to align the sheets stacked on the stacking unit in a sheet conveyance direction by making the grasping member contact the rear end of the stacked sheets after the sheets are stacked on the stacking unit, and controls the driving unit so that the grasping member performs the grasping operation when a following sheet is stacked on the stacked sheets.

  • Patent number: 8746670
    Abstract: A bundle of identical book blocks composed of a plurality of folded print sheets or signatures standing upright on lower edges of the printed sheets or book blocks. The book blocks are formed with first and last book block sections having different dimensions. A quadrangular bundle is formed from the book blocks by aligning first limit surfaces of the book block sections flush with each other along one of the two side surfaces or along the upper or lower surfaces of the bundle so that a second limit surface of the first book block section opposite the first limit surface of the first book block section projects with an offset with respect to a limit surface of the last book block section opposite the first limit surface of the last book block section. The bundle is compressed and then secured.

  • Patent number: 8740211
    Abstract: A sheet post-processing apparatus which is capable of preventing a stapling position and a folding position from being out of alignment when a stapling process is carried out. A sheet bundle, which is stacked in a housing guide, is stapled by a stapler using a staple at the stapling position. The sheet bundle is folded at a position of the staple after the stapling. After the stapling, the sheet bundle is moved from the stapling position to the folding position. During the movement, the staple is detected using a staple sensor disposed at a predetermined location between the stapling position and the folding position. Based on a moving distance of the sheet bundle before the staple is detected after the stapling process, a position of the sheet bundle with respect to the stapler for stapling on a subsequent sheet bundle is corrected.
