  • Patent number: 7775519
    Abstract: A sheet feeding apparatus includes a sheet stacking section configured to stack a number of sheets, a sheet feeding mechanism configured to feed the sheet stacked on the sheet stacking section one by one, and an intermediate conveying device configured to convey the sheet fed from the sheet feeding mechanism to an image forming apparatus. The intermediate conveying device includes a plurality of sheet conveying devices arranged in an intermediate sheet conveying path at certain intervals to convey the sheet fed from the sheet feeding mechanism, at least one driving device configured to drive each of the plurality of sheet conveying devices, and a plurality of sheet detecting devices arranged in the intermediate sheet conveying path at certain intervals to detect a sheet length by detecting at least one of a leading edge and a trailing edge of the conveyed sheet.

  • Patent number: 7651090
    Abstract: A paper conveyance apparatus includes a stacking portion; a feeding mechanism to extract and feed paper from the stacking portion one sheet at a time; and an intermediate portion for conveying the fed paper to the vicinity of a feeding port or feeding device of a main body of an image forming apparatus. The intermediate portion includes a plurality of conveyance devices and a plurality of paper detecting devices disposed from the upstream side to the downstream side of a conveyance path. The paper conveyance apparatus further includes a control device for reducing the conveyance speed of the plurality of conveyance devices when the leading edge of the paper is detected by a detecting device disposed at least one device further toward the upstream side than a paper detecting device disposed furthest downstream of the plurality of detecting devices.
