摘要： In a sheet processing apparatus that is required for high productivity, it is needed to execute skew correction of a sheet in a short time. Thus, when the sheet is struck against a roller or a skew correction member at a high speed to execute skew correction, it may cause a scratch or a noise caused by an impact. Accordingly, the sheet is struck against a skew correction stopper that is moving at a speed slower than a sheet conveyance speed to execute skew correction.

摘要： A sheet processing apparatus capable of high-speed and accurate detection of a lateral displacement and a skew of a sheet. A motor laterally shifts the sensors during sheet conveyance by a conveying motor, to determine first and second positions of the sheet lateral edge detected respectively by first and second sensors. A finisher controller determines a third position of the lateral edge of the sheet closer to a sheet trailing edge, based on the first and second positions and an amount of conveyance of the sheet from when the first position is detected to when the second position is detected. A lateral displacement of the sheet is corrected by laterally shifting the sheet according to the third position of the sheet lateral edge.

摘要： A sheet processing apparatus which is capable of improving the productivity of sheet processing as much as possible. An image forming apparatus forms an image on a sheet. A finisher is connected downstream of the image forming apparatus and performs post processing on the sheet. The finisher moves at least one of the sheet and a punching unit to adjust a position for punching holes in the sheet. The finisher determines whether or not a post-processing apparatus connected upstream of the finisher is provided with a correction mechanism for correcting a position of a sheet in a direction orthogonal to a sheet conveying direction. When the post-processing apparatus is provided with the correction mechanism, the finisher causes the image forming apparatus to be set such that a sheet conveying interval becomes shorter than when the post-processing apparatus is not provided with the correction mechanism.

摘要： A sheet processing apparatus includes a stack tray, a stapler, a stapler moving device, and an aligning member. When a stapling process is performed at least two staple positions of the sheet bundle stacked on the stack tray using the stapler, the stapler is moved to the next staple position by relative movement in which the stapler and the sheet bundle are moved in the opposite directions by the stapler moving device and the aligning member respectively. When the number of sheets in the sheet bundle or a weight of the sheet bundle is lower than a predetermined value, a moving speed of the sheet bundle is set faster than a moving speed of the sheet bundle at which the number of sheets in the sheet bundle is not lower than the predetermined value or the weight of the sheet bundle is not lower than the predetermined value.

摘要： A discharged sheet is conveyed, by a sheet conveying portion movable above sheet stacking portions while supporting a sheet, to selected one among plural sheet stacking portions. When the sheet is conveyed to the selected sheet stacking portion by the sheet conveying portion, a member for preventing a bringing-together provided in the main body of the apparatus prevents a sheet bundle, stacked in a sheet stacking portion at the upstream side of the selected sheet stacking portion, from being brought together by the sheet conveyed above the upstream sheet stacking portion by the sheet conveying portion.

摘要： A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.

摘要： An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period.
