摘要:
A sheet processing apparatus capable of shortening time to align sheets. A first alignment member and a second alignment member are movable in a sheet width direction orthogonal to a sheet conveying direction, and align a sheet. A CPU controls the first and second alignment members to be moved in the sheet width direction. A skew sensor detects a skew amount and skew direction of the sheet. The CPU causes the first and second alignment members to be positioned at respective predetermined standby positions before the sheet is received between the first and second alignment member. Further, the CPU causes one of the first and second alignment members to be moved in a direction toward the sheet, based on the detected skew amount and skew direction, during conveyance of the sheet between the first and second alignment members.

An image forming apparatus comprises a paper detection mechanism configured to detect papers passing through a conveyance path. The paper detection mechanism includes a rotation shaft which extends in a direction orthogonal to a conveyance direction of the paper; a lever integrally arranged on the rotation shaft; a torsion coil spring which is arranged around the outer periphery of the rotation shaft to energize the front end of the lever so that the lever protrudes to the conveyance path; and a sensor which detects the conveyance of paper when the lever pressed by the paper pivots. The torsion coil spring integrally includes a main coil part which is composed of a plurality of turns of coil and has a preset diameter, and a large diameter coil part which is larger in diameter than the main coil part and less in the number of turns than the main body coil part.

A label sheet conveyance device is provided to more accurately automatically detect seams between label sheets in a label printer. Using a first threshold value that is set according to the mode of sensor output values for detecting the sheet portion between labels, and a second threshold value that is greater than the first threshold value for detecting holes in the label sheet, a label printer determines a sheet position where the sensor output value is equal to each threshold value. If a sheet position equal to the second threshold value is detected, the center of that sheet position is identified as the seam position. If a sheet position equal to the second threshold value is not identified and a sheet position equal to the first threshold value is identified, the center of that sheet position is identified as the seam position.
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.
摘要:
A method and an apparatus for laterally aligning a sheet in a processing machine, in particular a printing machine, carries out lateral sheet alignment on a cylinder of the printing machine, e.g. a feed cylinder. In order to achieve large correction distances in relation to a possible lateral movement capability of a gripper bar, the latter is prealigned prior to correction in such a way that, in the event of deviation from predetermined desired values, it is prealigned laterally to defined positions. A sheet-fed rotary printing machine having the apparatus, is also provided.

To provide a sheet conveying apparatus capable of enhancing an accuracy of correcting a skew of a sheet, and of preventing position shift of a sheet. The present invention provides a sheet conveying apparatus for conveying a sheet by a sheet conveying unit disposed along a sheet conveying path, including: a skew detection sensor for detecting a skew of the sheet with respect to a sheet conveying direction by a plurality of detection sensors disposed in a direction intersecting perpendicularly the sheet conveying direction; and a skew correction roller adapted to be pivotally moved in a direction of correction of a skew of the sheet in a state with the skewed sheet being held on the basis of a detection signal from the skew detection sensor, in which one of the plurality of detection sensors of the skew detection sensor is disposed nearly on an extension line from a pivotal movement center of the skew correction roller in the sheet conveying direction.

An automated banking machine (10) identifies and stores documents such as currency bills deposited by a user. The machine then selectively recovers such documents from storage and dispenses them to other users. The machine includes a central transport (70) wherein documents deposited in a stack are unstacked, oriented and identified. Such documents are then routed to storage areas in recycling canisters (92, 94, 96, 98). When a user subsequently requests a dispense, documents stored in the storage areas are selectively picked therefrom and delivered to the user through an input/output area (50) of the machine.
