| 20090033028 | SHEET PROCESSING APPARATUS AND SHEET PROCESSING METHOD - A sheet processing apparatus includes a first detector configured to detect a leading edge of a sheet conveyed in a conveying direction, a second detector provided on a downstream side of the first detector in the sheet conveying direction to detect the leading edge of the sheet conveyed, a punching portion, in the downstream side of the first detector in the sheet conveying direction, to move in a sheet width direction crossing the sheet conveying direction and perform a punching process for the sheet, an edge detector configured to move in the width direction together with the punching portion and detect the edge of the sheet conveyed in the width direction, and a controller, on the basis of at least either of information of a conveying speed of the sheet and a sheet length in the conveying direction, when the edge detector starts movement in the width direction after the first or second detector detects the leading edge of the sheet, to judge whether the edge detector can detect the edge of the sheet or not, as a result of the judgment, selecting the detector positioned on the most downstream side in the conveying direction among the first and second detectors which can be used, and when the selected first or second detector detects the leading edge of the sheet conveyed, permitting the edge detector to start movement to detect the edge of the sheet in the width direction. | 02-05-2009 |
| 20090057991 | CONNECTION APPARATUS FOR CONNECTING IMAGE FORMING APPARATUS AND SHEET POST-PROCESSING APPARATUS - There is provided a connection apparatus for connecting an image forming apparatus and a plurality of sheet post-processing apparatuses. This connection apparatus has a flapper portion for switching a plurality of conveying paths going toward the plurality of sheet post-processing apparatuses. Sensors are provided near inlet rollers and near output rollers, respectively. Outputs of the sensors are inputted to a wired OR circuit, so that an output of the wired OR circuit is supplied to a CPU of one of the connected sheet post-processing apparatuses. | 03-05-2009 |
| 20090230612 | SHEET LOADER AND IMAGE FORMING APPARATUS - An image forming apparatus including a sheet loader, the sheet loader including: a discharger configured to discharge a first sheet and a second sheet after the first sheet; a tray configured to support the second sheet on the first sheet; a support configured to support the first sheet on the tray; a controller configured to control the support to lower a first angle than a second angle, the first angle being an angle of the first sheet against a direction to which the discharger discharges the second sheet at a position where the second sheet hits on the first sheet, the second angle being an angle of the tray against the direction at a position where the first sheet hits on the tray. | 09-17-2009 |
| 20100119245 | PAPER DISCHARGE DEVICE AND IMAGE FORMING APPARATUS - It is an object of the present invention to provide a paper discharge device that can sort sheets on a tray. The paper discharge device has paper discharge rollers, a tray and a driving mechanism. The paper discharge rollers are configured to discharge a sheet having an image formed thereon. The tray is configured to be stacked with the sheet discharged from the paper discharge rollers. The driving mechanism is configured to move the tray in a direction approaching the paper discharge rollers and a direction away from the paper discharge rollers and vary a stacking position of the sheet on the tray. | 05-13-2010 |
| 20100194024 | TRAY, SHEET POST-PROCESSING APPARATUS, AND SHEET-ALIGNMENT METHOD - According to one embodiment, a tray includes a take on surface on which a sheet is placed, a projecting portion configured to stick out from the take on surface, and a slip stopper including a sheet-slip stopper portion having a larger frictional coefficient with the sheet than the take on surface has. The slip stopper sticks the sheet-slip stopper portion out from the take on surface when the sheet comes into contact with the projecting portion. | 08-05-2010 |
| 20110065056 | IMAGE DECOLORING DEVICE - An image decoloring device includes: a decoloring processing unit configured to perform decoloring for removing the color of a decolorable colorant; a sheet carrying unit configured to transfer a sheet and causing the sheet to pass through the decoloring processing unit; a print condition detection unit arranged upstream of a direction in which the sheet is transferred by the sheet carrying unit with respect to the decoloring processing unit, the print condition detection unit obtaining print condition information indicating the print condition of an image formed on the sheet; and a process controlling unit configured to control the decoloring processing unit based on a result of detection given from the print condition detection unit. | 03-17-2011 |
| 20110065574 | IMAGE DECOLORING APPARATUS, IMAGE DECOLORING METHOD, AND SHEET TRANSFER APPARATUS - The present invention provides an image decoloring apparatus including a plurality of, at least three, sheet load portions, each of the portions being able to be loaded with a sheet, an decoloring portion which performs decoloring an image on a sheet formed with the decolorable colorant, a first sheet transfer portion which transfers the sheet loaded in each of the plurality of sheet load portions to the decoloring portion, and a second sheet transfer portion which transfers the sheet after the decoloring is performed thereto by the decoloring portion to each of the plurality of sheet load portions. | 03-17-2011 |
| 20110074086 | DECOLORIZING DEVICE AND METHOD FOR CONTROLLING DECOLORIZING DEVICE - According to one embodiment, a decolorizing device includes a first stacker to stack sheets to be decolorized images on the sheets, a second stacker arranged adjacent to the first stacker, wherein the sheets stacked on the first stacker is kept waiting on the second stacker in order to be decolorized the images, a pressing unit to urge the sheets stacked on the second stacker downward and keep the sheets stacked on the second stacker flat, an image decolorizing unit to decolorize the images on the sheets, and a sheet feed unit positioned on an upper surface of the pressing unit to convey the sheets pressed on the pressing unit from the second stacker to the image decolorizing unit. | 03-31-2011 |
| 20110089625 | CONNECTION APPARATUS FOR CONNECTING IMAGE FORMING APPARATUS AND SHEET POST-PROCESSING APPARATUS - A sheet post-processing apparatus or a connection apparatus has a flexible paper guide provided in a position of the inlet rollers, having a length ranging from an upstream side of the sensor to a downstream side of the sensor with respect to the conveying path, having a cut off in a portion corresponding to the sensor. | 04-21-2011 |
