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.

Sheet processing apparatus and image forming apparatus having the same

A sheet processing apparatus includes a stack portion on which sheets conveyed in a conveying direction are stacked, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in a crossing direction crossing the conveying direction by contacting an end of the sheet bundle in the crossing direction, a second regulating portion regulating a position of the sheet bundle in the conveying direction by contacting an end of the sheet bundle in the conveying direction, a first binding device which moves in the crossing direction and binds by a staple, a second binding device which moves and binds without a staple, and a controller which controls the first and second binding devices. The first and second binding devices bind the corner portion of the sheet bundle.

A sheet binding processing apparatus including a processing tray, a sheet positioning device, a first binding device, a second binding device, a driving device which moves the second binding device to a binding position where the sheets positioned by the sheet positioning device are to be bound and to a retracting position for retracting to the outside of the sheets positioned by the sheet positioning device, and a controller which controls the driving device and causes the second binding device to be located at the retracting position when the first binding device binds sheets.

Sheet binding processing apparatus and image forming system having the same

In an apparatus structure having a sheet discharge mode to store sheets at a stack tray from a sheet discharging path and a sheet discharge mode to store binding-processed sheet bundles with collating and stacking, sheet holding means is arranged above a sheet placement face of the stack tray as a sheet pressurization force being variable in two steps, and then, the pressurization force of the sheet holding means is adjusted in two steps in accordance with the sheet discharge mode for storing sheets at the stack tray.

Sheet stack tray having sheet pressurizing member

In a sheet storing apparatus of the present invention, a tailing end supporting member which temporarily supports a tailing end of a dropping sheet bundle is arranged between a discharging port of a processing tray to discharge the sheet bundle and the upmost sheet on a stack tray as being movable between an operating position above a sheet placement face and a waiting position outside the stack tray.

Sheet storing apparatus, post-processing apparatus and image forming system having the same

To provide a sheet post-processing apparatus enabling a sheet to be aligned in a predetermined collection position irrespective of the basis weight of the sheet and image formation surface in dropping and collecting the sheet onto a tray from a sheet discharge outlet, the apparatus has a tray for collecting a sheet from the sheet discharge outlet, and a sheet discharge rotating body for transferring the sheet that is carried out to the tray toward a sheet end regulation member, and is configured to be able to adjust the timing of shifting the sheet discharge rotating body to an operation position engaging in the sheet from a withdrawal position above the tray corresponding to image formation conditions of the sheet.

Sheet post-processing apparatus and image formation system provided with the apparatus

An image forming apparatus in which an original reading portion is disposed in an upper portion of the apparatus main body, a feed portion is disposed in a lower portion of the apparatus main body, and a printing portion is disposed between the original reading portion and the feed portion as an image forming system, is configured as follows. A paper post-processing portion that can perform a plurality of types of paper post-processing for recording paper transported from the apparatus main body after printing by the printing portion is finished, and a discharge portion to which recording paper is discharged after paper post-processing by the paper post-processing portion is finished, are disposed in a space of the apparatus main body formed by the original reading portion, the printing portion, and the feed portion.

Image forming apparatus with switchback transport path in the stapling unit

An image forming apparatus in which an original reading portion is disposed in an upper portion of the apparatus main body, a feed portion is disposed in a lower portion of the apparatus main body, and a printing portion is disposed between the original reading portion and the feed portion as an image forming system, is configured as follows. A paper post-processing portion that can perform a plurality of types of paper post-processing for recording paper transported from the apparatus main body after printing by the printing portion is finished, and a discharge portion to which recording paper is discharged after paper post-processing by the paper post-processing portion is finished, are disposed in a space of the apparatus main body formed by the original reading portion, the printing portion, and the feed portion. The paper post-processing portion is provided such that it can slide relative to the apparatus main body. In a front face of the paper post-processing portion, a cover is provided that covers this front face. The discharge portion is provided such that it can be raised or lowered according to the quantity of stacked recording paper.

Image forming apparatus

In an image forming apparatus in which an original reading portion is disposed in an upper portion of the apparatus main body, a feed portion is disposed in a lower portion of the apparatus main body, and a printing portion is disposed between the original reading portion and the feed portion as an image forming system, a paper post-processing portion that can perform a plurality of types of paper post-processing for recording paper transported from the apparatus main body after printing by the printing portion is finished, and a discharge portion to which recording paper is discharged after paper post-processing by the paper post-processing portion is finished, are disposed in a space of the apparatus main body formed by the original reading portion, the printing portion, and the feed portion, and the paper post-processing portion is controlled according to print conditions selected when a print request is made.
