Furthermore, an upper surface of the return claw positioned in the protruded position functions as a guide portion that guides an underside of a sheet that has been manually fed. ## Claims ### Claim 1 A feeding apparatus, comprising: a stack portion on which a sheet is stacked; a first feed member capable of moving between a first positon in which the sheet stacked on the stack portion is fed and a second position that is a position where the first feed member that has moved upwards from the first position is positioned, the first member being capable of feeding the sheet to a first conveyance path; a separation member that separates a sheet fed by the first feed member; a second feed unit that is provided above the stack portion and that is capable of feeding the sheet, the sheet conveyed through a second conveyance path is made to enter the first conveyance path with the second unit; and a moving member that moves from a retracted position in which the moving member is retracted from the first conveyance path to a protruded position in which the moving member is protruded into the first conveyance path, wherein the second feed unit feeds the sheet while in a state in which the moving member is positioned in the protruded position. ### Claim 2 (depends on 1) The feeding apparatus according to claim 1, wherein the moving member moves the sheet near the separation member towards an upstream side in a feed direction by moving from the retracted position in which the moving member is retracted from the first conveyance path to the protruded position in which the moving member is protruded into the first conveyance path. ### Claim 3 (depends on 1) The feeding apparatus according to claim 1, wherein the moving member positioned in the protruded position includes a first guide portion that guides an underside of the sheet fed by the second feed unit. ### Claim 4 (depends on 3) The feeding apparatus according to claim 3, further comprising: a second guide portion provided above the stack portion, the second guide portion guiding the underside of the sheet fed by the second feed unit. ### Claim 5 (depends on 4) The feeding apparatus according to claim 4, wherein the second guide portion does not guide the underside of the sheet fed by the first feed member. ### Claim 6 (depends on 4) The feeding apparatus according to claim 4, wherein a recess that permits the moving member to move is formed in the second guide portion. ### Claim 7 (depends on 4) The feeding apparatus according to claim 4, wherein the second guide portion includes an extended portion, the extended portion guiding the underside of the sheet, at a position that is the same as a position of the recess in a sheet feed direction and at a position that is different from a position of the recess in a sheet width direction orthogonal to the feed direction. ### Claim 8 (depends on 1) The feeding apparatus according to claim 1, wherein the moving member positioned in the protruded position is positioned above an uppermost surface of the sheet stacked on the stack portion. ### Claim 9 (depends on 1) The feeding apparatus according to claim 1, further comprising: a conveyance member that opposes the separation member and that conveys the sheet, wherein the separation member is capable of moving between a contact position in which the separation member abuts against the conveyance member, and a separated position in which the separation member is separated from the conveyance member. ### Claim 10 (depends on 9) The feeding apparatus according to claim 9, further comprising: a control unit that controls the first feed member, the second feed unit, and the moving member, wherein the control unit feeds the sheet with the second feed unit while in a state in which the first feed member is retracted upwards, the moving member is positioned in the protruded position, and the separation member is separated from the conveyance member. ### Claim 11 (depends on 1) The feeding apparatus according to claim 1, wherein the second feed unit includes an opening portion, the second feed unit feeding the sheet inserted into the opening portion. ### Claim 12 (depends on 1) The feeding apparatus according to claim 1, further comprising: an image forming portion that forms an image on the sheet that has been separated by the separation member.
