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 8):
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 shaft member disposed on the swing axis and configured to be rotated by a driving source; a rotary driving member supported on the shaft member and configured to rotate on the swing axis; 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 to rotate the rotary pick-up member in a rotational direction along with the sheet feeding direction in a case where the rotary driving member rotates in a first rotational direction, the first rotational direction being 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 an upstream side of the rotary driving member with respect to the swing axis moves upward; and a one-way clutch disposed between the shaft member and the rotary driving member and configured to transmit rotation of the shaft member in the first rotational direction to the rotary driving member and to allow the rotary driving member to rotate in the first rotational direction relative to the shaft member.
