  • Publication number: 20100252980
    Abstract: When a sheet bundle is being conveyed by any one pair of plural pairs of rollers independently movable toward and away from the bundle sheet, before the bound portion of the sheet bundle passes the pair of rollers, the pair of rollers on the downstream side nearest to the bound portion are separated from the sheet bundle, and the pairs of rollers more downstream than that pair convey the sheet bundle. Thereby, it happens less often that the pairs of rollers gather the air collected between adjacent ones of the sheets of the sheet bundle to the bound portion to thereby cause a slack to the sheets, and the occurrence of wrinkles or twists in the sheet bundle can be reduced. Also, the pair of rollers are separated from the sheet bundle before the bound portion passes the pair of rollers, whereby it happens less often that the pair of rollers are damaged by the bound portion, and the sheet bundle can be conveyed smoothly.

  • Patent number: 7798482
    Abstract: A feeding roller is rotatable about an imaginary rotational axis extending in an axial direction and is configured to be rotatingly driven in a rotational direction for feeding a recording medium to a conveying path. A supporting section rotatably supports the feeding roller at a position in confrontation with the recording medium accommodated in a recording-medium accommodating section. A driving unit is configured to generate a rotational driving force. A transmitting unit is configured to transmit the rotational driving force to a central part of the feeding roller with respect to the axial direction. A guiding section prevents the recording medium accommodated in the recording-medium accommodating section from displacing in the axial direction. The supporting section rotatably supports the feeding roller in such a manner that an angle of the imaginary rotational axis relative to a reference direction can be changed by a predetermined amount.

  • Patent number: 7644919
    Abstract: When a new paper sheet is supplied onto a compiling tray, a sub-paddle holds down paper sheets having already been stacked on the compiling tray until a leading edge of the new paper sheet S touches the stacked paper sheets. Thereafter, the sub-paddle gets apart from the sheets stacked on the compiling tray with timing, with which the rear edge of the new paper sheet falls on the compiling tray.

    Abstract: This is a paper registration system that allows for a lateral reset while the paper is present in the nip space. By separating the nips, the carriage can move to reset position for the next sheet while the previous sheet is still present in the carriage. In addition, the configuration of the system of the invention is reduced or elimination of reaction forces on the carriage lead screw is provided. The registration embodiments of the present system are especially useful in a high speed marking system.

  • Publication number: 20090309298
    Abstract: This application relates to systems and methods for determining the lateral component of skew for a sheet of media. First, the skew angle of a sheet of media is determined. Then, the lateral component of the skew is determined. During a lateral registration operation, the lateral component of the skew is accounted and compensated for. In one implementation, the slope of the angle of the skew may be determined by taking the regression of the function characterizing the edge of the sheet as it passes an edge detection sensor.

  • Publication number: 20090309291
    Abstract: To provide an image forming apparatus that can highly accurately position and convey, even if an inter-sheet distance of sheets to be conveyed is reduced, the sheets from registration rollers to a transfer position when a toner image on an image bearing member moving at process speed is transferred onto the sheet in the transfer position. A sheet fed from a paper feeding cassette by a pulse-motor driven paper feeding roller is conveyed to pulse-motor driven registration rollers by pulse-motor driven conveying rollers. When the sheet is conveyed to the transfer position according to restart of the registration rollers, the sheet is conveyed by the registration rollers at sheet conveying speed different from the process speed before the leading end of the sheet reaches the transfer position and is conveyed at the process speed after that.

  • Patent number: 7631868
    Abstract: A retractable scuffer includes an arm with foldaway drive wheels connected thereto that are independently pivotable to ensure even drive force on a sheet. The drive wheels flips down in a counter clockwise direction as the scuffer arm is driven to an extended position by a lead screw mechanism. This provides a shallow angle of contact with the sheet and allows the sheet to be pulled against a registration gate by the drive wheels versus being pushed, thereby eliminating unwanted reaction forces inherent in existing systems that push a sheet against a registration gate.

    Abstract: An aspect of the invention provides a sheet conveying apparatus, an image forming apparatus, and an image reading apparatus, in which generation of skew feeding caused by the shock in pressure contact of a rotation body can be reduced. An interlocking mechanism brings a driven roller 222 biased by a biasing member into pressure contact with a feeding portion 221c of a driving roller 221 in conjunction with rotation of the driving roller 221. The driving roller 221 includes a non-feeding portion 221d in a circumferential surface thereof. The driven roller 222 is caused to abut on a pressure holder 225 before the driven roller 222 moved in a direction in which the interlocking mechanism brings the driven roller 222 into the pressure contact with the driving roller 221 is brought into the pressure contact with the driving roller 221.
