20080315492 | SHEET PROCESSING APPARATUS - In a sheet processing apparatus that performs processing for sheets after image formation such as sorting or stapling of the sheets, sheets conveyed into a waiting tray are temporarily stopped while being kept clamped by a driving roller and a pinch roller in the waiting tray and the clamping is once released. A waiting tray unit on a left side is shifted to a right side by a predetermined amount, whereby an end of the stacked sheets is pushed and shifted by a lateral wall on the left side. Thereafter, the sheets are clamped again by the roller pair and discharged. | 12-25-2008 |
20080315503 | SHEET PROCESSING APPARATUS - In a sheet processing apparatus that, for example, sorts or staples sheets after image formation, when preceding finishing is not completed on a processing tray, a third sheet fed anew into a waiting tray of a sheet placing member configuring a sheet waiting unit, which temporarily puts a sheet conveyed thereto on standby, is stacked to be shifted such that leading ends of second and third sheets are located further on a conveying direction upstream side than a leading end of a first sheet. Consequently, longitudinal alignment in the processing tray after that is surely performed. | 12-25-2008 |
20080317530 | FASTENING STRUCTURE FOR ROTATING MEMBER - In a fastening structure for a rotating member such as a paddle, projections are provided in a groove of the paddle, the center of a parallel pin and the center of a hole for the parallel pin of a shaft are shifted from each other to press the parallel pin to one side, and the parallel pin is loose-fit by the projections to eliminate backlash between the groove of the paddle and the parallel pin and eliminate a cause of noise. | 12-25-2008 |
20080317534 | SHEET PROCESSING APPARATUS - A sheet processing apparatus that performs processing for sheets such as sorting or stapling of the sheets after image formation includes a motor that controls a rotating position of a sheet pushing member. When a leading end of a sheet passes, after the leading end of the sheet reaches a pivoting roller, a rotating position of the sheet pushing member is controlled according to a conveyance condition during the passage of a trailing end of the sheet. The sheet pushing member is rotated and, when the trailing end of the sheet passes, the sheet is conveyed while a charge removing brush is pressed against the sheet. | 12-25-2008 |
20090166946 | SHEET FINISHING APPARATUS - According to an aspect of the invention, a shifter shifts sheets before stapling in a continuous stapling mode. A bundle of sheets is immediately discharged from the shifter after the stapling. In a sorting mode, the bundle of sheets is discharged from the shifter while the bundle of sheets is shifted in a direction perpendicular to a discharge direction of the bundle of sheets. A friction force applied to a bundle of sheet T in the discharging is distributed in the discharge direction and a direction perpendicular to the discharge direction. | 07-02-2009 |
20100193113 | SHEET FINISHING APPARATUS, SHEET FINISHING METHOD AND IMAGE FORMING APPARATUS - A sheet finishing apparatus includes a cutter unit which is disposed on a conveyance path of a sheet, and forms a cut for tag formation in the sheet from a starting point close to a center line of the sheet orthogonal to a conveyance direction, a folding unit which is disposed downstream of the cutter unit on the conveyance path, bends the sheet around the center line, and raises an area defined by the cut in the sheet by the bending to form the tag. | 08-05-2010 |
20100314823 | SHEET PROCESSING APPARATUS, FINISHING APPARATUS AND SHEET GUIDE METHOD - A sheet processing apparatus of an embodiment includes a spring member which supports a support leg provided on an end bottom of a finishing apparatus at a side of an image forming apparatus and is extendable in a height direction, a sheet feed port which is formed in the finishing apparatus to be opposite to a sheet discharge port of the image forming apparatus and has a width wider than a width of the sheet discharge port in the height direction, sheet discharge guides which are arranged to be opposite to each other at an exit of the sheet discharge port and sandwich a conveyance path of the sheet in the image forming apparatus, sheet feed guides which are arranged to be opposite to each other at an inlet of the sheet feed port and sandwich a conveyance path of the sheet in the finishing apparatus, electromagnets provided at ends of the sheet feed guides at a side of the sheet feed port, and magnetic members which are rotatably provided to ends of the sheet discharge guides at a side of the sheet discharge port and are attracted by the electromagnets. | 12-16-2010 |
20110031675 | STAPLING UNIT, SHEET FINISHING APPARATUS, AND STAPLING METHOD - Certain embodiments provide a stapling unit including a stapler, a processing tray, a stapler moving mechanism, a sensor configured to scan sheets in a sheet width direction, and a controller configured to drive the stapler. The controller measures sheet width of the sheets according to an output of the sensor. The controller calculates a center position between other two sheet edges each orthogonal to a sheet edge where the stapler drives staples into stapling positions. The controller allocates the stapling positions in the two places with reference to the center position. The controller moves the stapler moving mechanism to the stapling positions. | 02-10-2011 |
20110215514 | SHEET FINISHING APPARATUS, MOVING MECHANISM FOR SAME APPARATUS, AND MOVING METHOD FOR SAME APPARATUS - Certain embodiments provide a sheet finishing apparatus including: a machine body; a finishing mechanism; a frame structure; a base; plural first holders pivotally supported on the base and turn around vertical pivots; plural first wheels pivotally supported on the plural first holders and rotate around horizontal axles shifted from the pivots of the first holders; a second holder pivotally supported on the base and is directed downward from a part of the base, the part passing through an apparatus center, and turns around a vertical pivot; a second wheel pivotally supported on the second holder, rotates around a horizontal axle intersecting the pivot of the second holder, and has a greater diameter than a diameter of the first wheel; and an elastic member connected between the second holder and the base and extends and reduces a spacing between the horizontal axle of the second wheel and the base. | 09-08-2011 |
20130243504 | IMAGE DECOLORIZING DEVICE WITH MOVABLE CONTACT PARTS, AND RELATED METHOD - An image decolorizing device according to an embodiment comprises a heating unit configured to generate heat and apply the heat to a recording medium, and a pressure roller that forms a nip with the heating unit. The image decolorizing device further comprises a first contact part positioned in contact with the heating unit at a first position upstream of the nip in a rotation direction of the heating unit and fixed in the rotating direction, and a second contact part positioned in contact with the heating unit at a second position upstream of the nip in the rotation direction and fixed in the rotating direction. In the image decolorizing device, the first and second contact parts are configured to apply a voltage to the heating unit causing the heating unit to generate heat over a heating area between the first and second positions. | 09-19-2013 |
