  • Patent number: 5385340
    Abstract: A sheet-postprocessing apparatus includes a sheet discharger which discharges sheets to a stacker, the stacker including a first tray adjacent to the discharger for supporting trailing portions of the sheets discharged by the discharger and a second tray for supporting leading portions of the sheets, the second tray being movable in a vertical direction and disposed downstream of the first tray with respect to a sheet discharge direction, the trays being inclined so that sheets stacked thereon slide by their own weight, such that a stack of sheets supported on both trays are stapled by a stapler, the stapled set of sheets then being pushed out of the first tray to be stacked entirely by the second tray. The sheet post-processing apparatus operates in two modes, a stapling mode and a non-stapling mode wherein sheets discharged by the discharger bypass the first tray and are supported entirely by the second downstream tray.

  • Patent number: 5350169
    Abstract: A sheet stacking tray apparatus for receiving sheets discharged from an image forming apparatus such as a printer or copying machine. The sheets are correctly stacked, that is, without inclination or deviation. The tray apparatus according to the present invention is such that the speed at which the sheet is discharged to the tray apparatus is reduced when the tray apparatus receives the sheet material. And, the sheet is laterally shifted so as to correct the lateral deviation thereof. The tray is lowered in accordance with the amount of the sheets so as to keep a proper height thereof with respect to the discharging outlet from which it receives the sheet. An auxiliary sheet stacking plate is provided operable in association with the lowering of the tray so as to raise the sheet receiving side thereof so as to keep the sheet material on the tray horizontal.

  • Patent number: 4883265
    Abstract: A tray apparatus for stacking sheets discharged from an image forming apparatus such as a copying machine, a printer, a facsimile machine and other recording machines. The tray apparatus has a sheet aligning member in the form of an endless web which is contactable to the top surface of the sheet which has been discharged onto a tray or bin tray so as to displace the sheet in the opposite direction until the trailing edge of the sheet abuts a stopper member which is disposed adjacent that end of the tray which is near the discharging outlet. By doing so, the sheets discharged are aligned against the stopper member.

  • Patent number: 4717134
    Abstract: A sheet folding apparatus including a plurality of sheet processing units each having a couple of folding rollers, a deflector and a folding position controlling passage. One set of the apparatus is sufficient to effect two-folding, z-folding and reversed z-folding of the sheet. A guiding member is disposed closely adjacent to the nip of the folding roller couple for conveying the sheet out of the folding positions controlling passage and for forming a new fold. When the sheet is three-folded, an undesirable double fold is prevented, which may otherwise be produced by an undesirable fold formed adjacent to the already formed fold when the sheet is folded second time.
