  • Patent number: 8770569
    Abstract: A sheet processing apparatus is disclosed which includes front and back trailing-end reference fences that are movable and on which the sheet trailing-end abuts to align the sheet trailing-end; a side-stitching stapler that moves along the sheet trailing-end and binds a bundle of sheets aligned; a length-direction moving mechanism that moves the trailing-end reference fences in a sheet conveying direction; and a position changing unit that drives the length-direction moving mechanism to change the position of one of the trailing-end reference fences in the sheet conveying direction relative to the position of the other one. The front and back trailing-end reference fences are moved to change binding positions such that the distances from the sheet trailing-end to staple positions are made equal in front-side binding and in back-side binding.

  • Patent number: 8727345
    Abstract: A sheet discharging device includes: sheet discharging rollers that receive each of sheets conveyed thereto and discharge the sheets one by one; a shift tray on which the sheets discharged by the sheet discharging rollers are to be stacked; an air blower; and a CPU. The air blower forms an air layer between the shift tray and a sheet when the sheet is discharged onto the shift tray by the sheet discharging rollers, or between a sheet and the sheet that is already placed on the shift tray when the sheet is discharged. The CPU controls an air velocity of air to be delivered by the air blower based on sheet information, thereby causing the air layer to extend to the entire surface of the sheet.

  • Patent number: 8702087
    Abstract: A sheet handling apparatus includes a sheet reception unit configured to receive a sheet; an alignment unit configured to align the sheet in a conveying direction of the sheet, a trailing edge of the sheet in the conveying direction coming into contact with the alignment unit; and a moving unit configured to move the alignment unit along the sheet reception unit in the conveying direction. A first position for aligning and binding sheets and a second position located above the first position in the sheet reception unit are set for the alignment unit as receiving positions at which the sheet is received from the sheet reception unit.

  • Patent number: 8684307
    Abstract: There is provided a space-saving and compact swing type door structure of an aircraft restroom, in which a door is automatically closed and which is easy to use for a passenger using the restroom. The swing type door (40) is slidably hung at its upper end edge (44) from a rail disposed at an upper portion of a door frame by a guide structure including a slide pin (46) and is turnably connected in a predetermined position different from the hung position to the door frame by a linkage (60). Swinging operation in opening the door (40) deforms a spring provided in an automatic closing device (50). When a hand is released from the door (40), the door (40) is constantly biased in a closing direction by spring resilience through the linkage (60) and automatically returns to a closed position. Therefore, the restroom becomes easy to use, an aisle in front of the restroom can be used in an emergency, and it is possible to avoid contingencies caused by false recognition of an escape hatch.

  • Patent number: 8485514
    Abstract: A sheet processing apparatus includes: a sheet stacking unit on which sheets are accommodated and stacked as a sheet bundle; an aligning member that is movable along a trailing end, in a conveying direction, of the sheet bundle stacked on the sheet stacking unit and that aligns the trailing end of the sheet bundle in the sheet conveying direction by abutting thereon; a binding unit that moves along the trailing end of the sheet bundle in the sheet conveying direction and binds the aligned sheet bundle; and a moving unit that moves the aligning member in the sheet conveying direction. A distance from the trailing end of the sheet bundle in the sheet conveying direction to a binding position is adjusted by moving the aligning member in the sheet conveying direction.

  • Patent number: 8393618
    Abstract: A skew correction device includes a first conveying unit arranged in a sheet conveying path; a second conveying unit arranged downstream of the first conveying unit in a conveying direction of a sheet; and a skew correction unit. When the sheet is unfolded paper, the skew correction unit performs a first skew correction that corrects for the skew of the sheet so that a leading edge of the sheet conveyed by the first conveying unit abuts on the second conveying unit that is stopped. When the sheet is fold paper, the skew correction unit performs a second skew correction that corrects for the skew of the sheet so that a leading edge of the sheet conveyed by the first conveying unit abuts the second conveying unit and the second conveying unit is driven in a reverse direction to the conveying direction at a predetermined operational timing.
