摘要： A sheet processing apparatus includes a conveying portion which can move a sheet in a sheet conveying direction and in a sheet width direction, a moving portion which moves the conveying portion in the sheet width direction, a punching portion which punches a hole in the sheet, and a pressing portion which presses an upstream end of the sheet. The sheet forms a first loop to correct skew feeding while the sheet is conveyed with its downstream end abutted against the conveying portion in the sheet conveying direction. The conveying portion conveys the sheet. The moving portion moves the conveying portion in the sheet width direction to correct lateral registration of the sheet. The pressing portion presses an upstream end of the sheet in the sheet conveying direction and forms a second loop of the sheet to correct skew feeding. The sheet is positioned with reference to the pressing portion.

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 stacking apparatus which is capable of efficiently stacking sheets of various sizes while making efficient use of space therein to realizing compactness of the apparatus. Stacker trays that are driven by respective tray lift motors perform a lifting/lowering operation to have sheets stacked thereon. Selection is made according to the size of sheets between a first stacking mode for stacking sheets having a size not larger than a predetermined size on one of the stacker trays and a second stacking mode for stacking sheets having a size larger than the predetermined size in a state extending on the stacker trays. When it is determined that one of the stacker trays is faulty, execution of the second stacking mode is inhibited, and execution of the first stacking mode using the other stacker tray is permitted.

摘要： A sheet conveying device which has a reduced size and is capable of detecting the amount of lateral sheet registration deviation and correcting the deviation at high speed. The sheet conveying device includes shift roller pairs for conveying sheets, and a shift unit for shifting a conveyed sheet in a direction orthogonal to a sheet conveying direction. After the sheet has reached a position where it is to be detected by a lateral registration deviation-detecting sensor unit, a CPU causes the sensor unit and the sheet to be shifted in respective opposite directions, detect a sheet lateral edge, and thereby measure the position of the sheet lateral edge. Further, the CPU causes the sheet to be shifted based on a result of the measurement, such that the sheet lateral edge is aligned with a predetermined position.

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.
