Abstract:
A sheet feeding apparatus includes a rotary pick-up member, a rotary feed member and a separation member. A holding member holds the rotary pick-up member rotatably and is configured to swing on a swing axis positioned upstream from a rotation axis of the rotary pick-up member in a sheet feeding direction. A rotary driving member is on the swing axis of the holding member. A drive transmission portion is supported by the holding member and is configured to transmit (i) rotation of the rotary driving member to the rotary pick-up member in delivering the sheet from a sheet stacking portion toward a separation portion and (ii) rotation of the rotary pick-up member rotated by the sheet to the rotary driving member in conveying the sheet by the rotary feed member after a leading edge of the sheet in the sheet feeding direction has reached the separation portion.

Claim (Index 1):
A sheet feeding apparatus comprising:\n a sheet stacking portion on which a sheet is stacked; a rotary pick-up member configured to rotate, in contact with a top surface of the sheet stacked on the sheet stacking portion, and deliver the sheet in a sheet feeding direction; a rotary feed member disposed downstream from the rotary pick-up member in the sheet feeding direction and configured to convey the sheet; a separation member disposed in contact with the rotary feed member and configured to separate the sheet conveyed by the rotary feed member from another sheet at a separation portion formed between the separation member and the rotary feed member; a holding member holding the rotary pick-up member rotatably and configured to swing on a swing axis positioned upstream from a rotation axis of the rotary pick-up member in the sheet feeding direction; a rotary driving member configured to rotate, being driven by a driving source, on the swing axis of the holding member; and a drive transmission portion supported by the holding member and capable of transmitting rotation from the rotary driving member to the rotary pick-up member and vice versa, the drive transmission portion being configured such that\n (i) in delivering the sheet stacked on the sheet stacking portion toward the separation portion, the drive transmission portion transmits rotation of the rotary driving member, performed in a first rotational direction, to the rotary pick-up member and rotates the rotary pick-up member, wherein the first rotational direction is a rotation direction that a downstream side of the rotary driving member with respect to the swing axis in the sheet feeding direction moves downward and an upstream side of the rotary driving member with respect to the swing axis moves upward, and \n (ii) in conveying the sheet by the rotary feed member after a leading edge of the sheet in the sheet feeding direction has reached the separation portion, the drive transmission portion transmits rotation of the rotary pick-up member rotated by the sheet to the rotary driving member and rotates the rotary driving member in the first rotational direction.
