271300240 | Including gripper couple | 8 |
20100052239 | DISCHARGE DEVICE AND IMAGE FORMING APPARATUS - A discharge device comprises a discharge roller unit including a first discharge roller and a second discharge roller, and deforming a sheet on which an image is formed, the sheet being deformed such that the sheet is recessed toward one of the rollers when the sheet is fed between the first discharge roller and the second discharge roller. | 03-04-2010 |
20100052240 | Image Forming Apparatus - A pair of conveyor rollers arranged in an image forming apparatus to convey a recording sheet which has been subjected to a fixing process toward outside of a body of the apparatus is configured to be shiftable relative to the body between a first position and a second position. A first holding member is configured to support one of the conveyor rollers in such a manner that a conveyor roller supported by the first holding member is swingable around a pivot located adjacent to a sheet conveyance path upstream of the supported conveyor roller to allow the pair of conveyor rollers to be shifted between the first position and the second position. The first holding member comprises a sheet guide portion which provides a variable-position guideway extending from a position located upstream along the sheet conveyance path toward a peripheral surface of the supported conveyor roller. The sheet guide portion is configured to come to a position suitable to guide the recording sheet toward a nip position at which the pair of conveyor rollers nips the recording sheet at least when the pair of conveyor rollers is shifted to the first position. | 03-04-2010 |
20100164164 | SHEET CARRYING DEVICE - A sheet carrying device includes: a sheet carrying unit having a first sheet carrying unit and a second sheet carrying unit, at least one of which has a sheet carrying force changing along a direction orthogonal to a traveling direction of a sheet, the first sheet carrying unit carrying the sheet in the traveling direction, the second sheet carrying unit carrying the sheet in the traveling direction together with the first sheet carrying unit; and a control unit which controls the carrying by the first sheet carrying unit and the carrying by the second sheet carrying unit on the basis of a result of detection from a detection unit which detects an inclination of the sheet that is traveling. | 07-01-2010 |
20120025443 | POST-PROCESSING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME - An image forming apparatus includes a sheet aligning mechanism that aligns a sheet of medium stacked by causing the sheet of medium to move in a shift direction orthogonal to a feed direction. The sheet aligning mechanism includes: a pair of alignment members having a pair of alignment surfaces; a rotational waiting position detector that detects whether the alignment members have moved to a rotational waiting position at which the alignment members wait; a rectilinear waiting position detector that detects whether the alignment members have moved to a rectilinear waiting position; and a post-processing controller that performs correction of a rotational angle and amount of movement of the alignment members performed by a rotational movement drive mechanism, based on signals output from the rotational waiting position detector and the rectilinear waiting position detector. | 02-02-2012 |
20120175837 | IMAGE PROCESSING DEVICES AND SHEET FEEDING DEVICES - An image processing device comprises a first feeding unit coupled to a second feeding unit via a sheet feeding path and is configured to feed a sheet toward the second feeding unit in a sheet feeding direction via the sheet feeding path. The first feeding unit comprises a first shaft configured to rotate in the sheet feeding direction, and the second feeding unit comprises a second shaft configured to rotate in the feeding direction. The first feeding unit and the second feeding unit are configured to feed and hold the sheet simultaneously. The image processing device further comprises a first supporting member which rotatably supports the first shaft, a second supporting member which rotatably supports the second shaft, and a third supporting member which rotatably supports the first shaft and/or the second shaft at a location different than the first supporting member and/or the second supporting member. | 07-12-2012 |
20130056921 | AUTOMATIC DOCUMENT FEEDER, IMAGE SCANNING DEVICE, AND METHOD FOR FEEDING ORIGINAL DOCUMENT - An automatic document feeder includes a feeding path and a plurality of feed roller sets. Through the feeding path, an original document is fed in one direction from a paper supply port to a paper discharge port. The plurality of the feed roller sets are arranged along the feeding path to be spaced apart from each other. When one side of an original document is scanned and when both sides of an original document are scanned, the plurality of the feed roller sets nip the original document to feed the original document along the feeding path. In this case, the plurality of the feed roller sets are all involved in feeding the original document. | 03-07-2013 |
20160039630 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - In response to an arrival of a first cleaning region of the cleaning sheet to a pre-registration roller pair, a control portion drives the pre-registration roller pair for a predetermined time and cleans the pre-registration roller pair by the first cleaning region by stopping a fed sheet drawing roller pair and a registration roller pair. Then, after an elapse of the predetermined time, as the cleaning sheet is conveyed and a second cleaning region of the cleaning sheet arrives at the registration roller pair, the control portion cleans the registration roller pair by the second cleaning region. | 02-11-2016 |
20160159595 | DEVICE AND METHOD FOR CONVEYING FLAT OBJECTS - A device for conveying and transferring flexible, flat objects with a gripper conveyor including a plurality of grippers that are movable along a conveying path in a conveying direction, and further with a conveying-way device that forms a conveying rest that, in a transfer region, is arranged below the conveying path such that objects that are released from grippers in the transfer region are deposited onto the conveying rest. The device includes a pressing circulatory device that acts upon the transfer region and has a plurality of outwardly directed pressing arms. The pressing circulatory device is designed, in the transfer region, to press the objects to be transferred with the pressing arms onto the conveying rest such that the objects can be deposited onto the conveying rest in a guided and controlled manner. | 06-09-2016 |
