    摘要: A sheet processing apparatus performs folding processing so that one end of a sheet exists inside the folded sheet. The sheet processing apparatus includes a transport path to guide a transported sheet, a rotating body pair capable of transporting the sheet in a first direction to perform folding processing, and in a second direction for switching back the sheet subjected to the folding processing, a folding blade that pushes the sheet to a nip portion of the rotating body pair, a press member that presses the sheet folded by the rotating body pair in the second direction, and a shift section that shifts the press member for pressing the sheet. In switching back the sheet, a control section controls transport of the sheet so that the one end of the sheet is halted within a region between the press member and a guide face of the transport path.

    摘要: A sheet processing apparatus includes a conveying portion conveying sheets; a stack portion staking the sheets; a first regulating portion regulating a position of a sheet bundle on the stack portion in a crossing direction; a second regulating portion regulating a position of a sheet bundle in the conveying direction; a first binding device moving in the crossing direction so that the first binding device moves between first and second sides of the sheet processing apparatus and to bind an upstream end portion of a sheet bundle by a staple at a plurality of positions in the crossing direction; a second binding device binding an upstream end portion of a sheet bundle, where the second regulating portion has contacted without a staple; and a controller causing, in a case that the first binding device binds a sheet bundle, the second binding device to be positioned outside the sheet bundle.

    摘要: A sheet processing apparatus includes a processing tray to place the sheet, a load tray provided on a downstream side of the processing tray in a transport direction, neat alignment plates provided outside a main body housing to shift in a width direction orthogonal to the transport direction and to align opposite sides of the sheet, a sheet support surface provided in a different position adjacent to the processing tray to support a sheet inserted from a manual feed opening, a binding processing apparatus to perform binding processing on sheets placed on the sheet support surface, a regulation surface to regulate a side edge of the sheet located at a side of the load tray, and a width-direction drive mechanism to shift the neat alignment plates between an alignment position aligning a sheet on the load tray in the width direction and a retract position different from the alignment position.

    摘要: A sheet processing apparatus includes a stacking section provided on the downstream side of a collecting section in a transport direction outside an apparatus housing, an alignment section provided on the downstream side of the collecting section in the transport direction, above the stacking section, to be able to shift in a predetermined movable region so as to align a sheet width direction orthogonal to the transport direction of the sheet to be stacked on the stacking section, a shaft-direction drive mechanism for shifting the alignment section in the width direction orthogonal to the transport direction, an alignment plate rotation shaft member for axially supporting the alignment section rotatably, a shaft-direction drive source for operating the shaft-direction drive mechanism, and a neat housing for storing the shaft-direction drive mechanism and the alignment plate rotation shaft member inside the housing.
