  • Patent number: 10124974
    Abstract: A paper feeding device according to an embodiment includes a paper feeding cassette that holds a plurality of sheets and has a stacking surface with an angle A relative to horizontal that changes depending on a quantity of sheets stacked thereon. A pickup roller feeds the plurality of sheets from the paper feeding cassette. A separation roller separates the plurality of sheets from each other in a case where the plurality of sheets are fed from the paper feeding cassette in an overlapped state. A guide unit has a guide surface which is inclined upwards on a downstream side thereof in the transport direction of the plurality of sheets. A drive unit changed an angle B of the guide surface relative to horizontal. A control device controls the drive unit to change the angle B based on the angle A.

    Abstract: A sheet separation transport mechanism according to the present disclosure includes a sheet feed member, a separation member, a support member, a sheet member and a concave portion. The sheet feed member feeds a sheet in a transport direction. The separation member is pressed onto the sheet feed member. The support member includes: a separation member retaining portion; and a guide portion which guides lead edges of a plurality of sheets to the downstream side along the inclined surface. The sheet member is adhered from the guide portion so as to overlap the separation member and has a frictional coefficient lower than the separation member. The concave portion is formed in the shape of a groove in a position of the guide portion where the sheet member is adhered such that the depth of the concave portion is greater than the thickness of the sheet member.

  • Publication number: 20130216291
    Abstract: Provided are a sheet feeding device and an image forming apparatus that are capable of accurately detecting an abnormality of a feeding state without erroneously detecting when a trailing edge of a preceding sheet and a leading edge of a subsequent sheet are fed in an overlaid state. The sheet feeding device includes ultrasonic wave sensors 6 and 7 that detect an overlaid state of a preceding sheet Sa and a subsequent sheet Sb fed from feeding portions 51, 317 to 319 and a controller 1 that continuously performs a detection of the overlaid state of a sheet fed from the feeding portion at a predetermined number of detecting points along a sheet conveying direction at every predetermined time and determines a number of detecting points where detects. Based on the determined number of detecting points, the controller determines that the overlaid state is normal or abnormal.

  • Publication number: 20130147107
    Abstract: A sheet feeder includes a sheet placing portion, a feeding member, a supporting body, a driver, an electromagnetic clutch and a retraction controller. The supporting body is capable of changing a posture between a sheet feeding posture of the feeding member and a retracting posture for retracting the feeding member. The electromagnetic clutch is capable of changing a state between an engaged state in which a drive force is transmitted to the supporting body and a disengaged state in which the drive force is not transmitted to the supporting body. The retraction controller stops the output of a drive force after the electromagnetic clutch is set in the engaged state and the supporting body is set to the retracting posture by the drive force, and sets the electromagnetic clutch in the disengaged state when an engagement keeping time elapses after the output of the drive force is stopped.
