20090026687 | SHEET PROCESSING APPARATUS AND SHEET PROCESSING METHOD - A sheet processing apparatus includes a first roller, a second roller configured to press the first roller to form a nip portion, a moving member opposite to the nip portion to move from a start position to an operation position approaching the nip portion, a pushing member supported on the moving member to press a sheet by an end thereof by movement of the moving member and push the sheet into the nip portion, and a third and fourth rollers positioned on both sides of the pushing member and supported on the moving member. | 01-29-2009 |
20090200726 | FINISHER, SHEET DISCHARGING METHOD AND IMAGE FORMING APPARATUS - A conveying unit has a nipping hook to nip a sheet bundle and conveys the sheet bundle while nipping the sheet bundle with the nipping hook. A discharge roller sequentially discharges the sheet bundle conveyed by the conveying unit. A stack unit stacks the sheet bundle conveyed by the conveying unit. A shutter is provided between the discharge roller and the stack unit. A push-out lever is fixed to the discharge roller. An opening is provided on one side of the shutter, and a push-out part which causes the push-out lever to protrude to the stack unit from the opening of the shutter with a rotation of the nipping pawl is provided on the nipping hook. The push-out lever caused to protrude to the stack unit by the push-out part pushes out the sheet bundle to the stack unit in accordance with the rotation of the nipping hook. | 08-13-2009 |
20100117287 | SHEET LOADING APPARATUS, SHEET POST-PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - A sheet loading apparatus has an ejecting member to eject a sheet; a loading member to load the sheet ejected by the ejecting member; and a movable member capable of moving in a state keeping contact with ejecting member side ends of the sheets loaded on the loading member. The movable member moves a distance equal to a moving distance of the loading member in the moving direction of the loading member. The sheet loading apparatus has a screen which is located between the loading member and the ejecting member and moves up and down, while waits at a position capable of avoiding interruption to the ejection of the sheet; and a first rotating member mounted to the screen in a location above the loading member and suspending the movable member. | 05-13-2010 |
20100119276 | SHEET FOLDING APPARATUS, IMAGE FORMING APPARATUS USING THE SAME, AND SHEET FOLDING METHOD - A sheet folding apparatus includes a fold unit which folds a center of a sheet bundle to form a fold line, and a reinforce roller which moves along the fold line while applying pressure to the fold line to reinforce the fold line. The reinforce roller includes plural sub-rollers which are concentrically coupled to each other in a rotation axis direction, and the respective sub-rollers apply different pressures to the fold line. | 05-13-2010 |
20110218091 | SHEET FINISHING APPARATUS AND SHEET FINISHING METHOD - According to an embodiment, there is provided a sheet finishing apparatus including a folding roller that nips the middle of bundle of sheets and forms a fold line, a fold reinforcing roller that reinforces the fold line by moving along the fold line while applying a pressure to the fold line, a stack tray that stacks the bundle and a control unit that sets the number of times of fold reinforcing performed by the fold reinforcing roller as a first number when it is determined that a quantity of stacked bundle on the stack tray is less than a predetermined standard quantity which is set to be less than a maximum stack quantity and sets the number of times of the fold reinforcing as a second number greater than the first number when it is determined that a quantity of the stacked bundle is greater than the predetermined standard quantity. | 09-08-2011 |
