摘要： A registration portion which conveys a sheet toward an image forming portion forming an image on the sheet includes a controlling portion which regulates a sheet skew feeding correction amount by the skew feeding correcting portion based on the sheet right angle degree detected by the end detection sensor. The controlling portion automatically calculates, from the sheet right angle degree detected by the end detection sensor, a skew feeding regulation amount used for making any one of the two sides, forming the corner of the sheet, parallel to the image and corrects the skew feeding of the sheet by the skew feeding correcting portion with the use of the skew feeding regulation amount so that any one of the two sides forming the corner of the sheet is parallel to the image.

摘要： A control portion controls a skew feed correcting portion so that a first skew feed correcting operation for correcting skew feed of a sheet while turning the sheet based on one edge of the sheet crossing a sheet conveying direction is performed in a case where a first alignment operation based on a position of one edge of the sheet is performed when a sheet processing portion processes the sheet. Further, the control portion controls the skew feed correcting portion so that a second skew feed correcting operation for correcting the skew feed of the sheet based on a side edge of the sheet parallel to the sheet conveying direction is performed in a case where a second alignment operation based on a position of the side edge of the sheet is performed when the sheet processing portion processes the sheet.

摘要： A sheet conveyance device that is capable of correcting skew of a sheet like an index sheet without complicating a use setting and without increasing a cost significantly. A plurality of conveyance units are arranged in a direction intersecting a sheet conveyance direction to convey a sheet. At least three detection sensors are arranged in a direction intersecting the conveyance direction at an upstream side from the conveyance units to detect the sheet. A skew amount computation unit measures a time difference between detection timings of a front end of the sheet by two of the at least three detection sensors except the detection sensor that detects first, and computes a front-end skew amount according to the time difference. A speed change unit makes the conveyance speeds of the conveyance units be different according to the front-end skew amount so as to correct the skew of the sheet.

摘要： Accurate sheet registration is achieved by measuring the arrival of a leading edge and/or a trailing edge of the sheet using a first sensor. Also, measuring a first position of the sheet using a second sensor on a lateral edge of the sheet. Then performing a first adjustment moving the sheet laterally using the first position measurement. The first adjustment actuated prior to the sheet reaching a third sensor for measuring a second position of the sheet.

摘要： A device for horizontally rotating flat articles supplied along a transport line (L) has a sliding plane (2) for restively receiving articles (F) in transit between the upstream and downstream branches (RM, RV). Two drawing groups are flanked and activated independently, each constituted by a lower roller (13, 14) and an upper roller (23, 24) rotating in an opposite direction, the rollers adheringly engaging with upper and lower surfaces of the flat articles (F). Command organs (10) activate the first and second drawing groups (3, 4), first in a same direction in phase relation with an entry of a flat article (F) arriving from the upstream branch (RM) and then in opposite directions in order to horizontally rotate the flat article (F) by a predetermined angle, and once more in a same direction for directing the rotated flat article (F) towards the downstream branch (RV) of the transport line (L), in a direction parallel to the entry direction.

摘要： The skew feeding amount of a sheet front end is calculated according to the difference between timings when activation sensors detect the sheet front end, and the skew feeding amount of the sheet side edge is calculated according to the difference between side edge positions of the sheet detected by the first side registration detection sensor or the second side registration detection sensor. Further, whether a sheet is a rectangular sheet or a non-rectangular sheet is determined before skew feeding of the sheet is corrected, and, when the sheet is determined to be a rectangular sheet, the skew feeding correcting portion is controlled based on one of the sheet side edge skew feeding amount and sheet front end skew feeding amount and the skew feeding correcting portion is controlled based on the sheet side edge skew feeding amount when the sheet is determined to be a non-rectangular sheet.
