A sheet feeding device configured to feed a sheet in a feeding direction, the sheet feeding device comprising: a main body comprising a feeding unit configured to feed the sheet to a conveying path along which the sheet is conveyed; a cover configured to pivot about a first axis relative to the main body between a closed position in which the cover closes the conveying path and an open position in which the cover exposes the conveying path; and a plate configured to pivot about a second axis which is parallel to the first axis and to contact and move away from the feeding unit, the plate extending toward a side opposite from the cover in the open position, wherein the second axis is closer to the cover than to the feeding unit in the feeding direction, wherein in a state in which the cover is in the closed position, at least a part of the cover is positioned on an upper side of the plate so as to be contactable with the plate, and wherein the at least a part of the cover comprises a first protrusion which, in the state in which the cover is in the closed position, protrudes in the feeding direction and is positioned on the upper side of the plate so as to be contactable with the plate: characterised in that: the cover comprises an edge portion positioned opposite to the first protrusion relative to the first axis, in a state in which the cover is in the open position, at least a part of the plate is positioned on an upper side of the edge portion of the cover so as to be contactable with the edge portion, and in the state in which the cover is in the open position, the edge portion is lower than a protruding end of the first protrusion. a main body comprising a feeding unit configured to feed the sheet to a conveying path along which the sheet is conveyed; a cover configured to pivot about a first axis relative to the main body between a closed position in which the cover closes the conveying path and an open position in which the cover exposes the conveying path; and a plate configured to pivot about a second axis which is parallel to the first axis and to contact and move away from the feeding unit, the plate extending toward a side opposite from the cover in the open position, wherein the second axis is closer to the cover than to the feeding unit in the feeding direction, wherein in a state in which the cover is in the closed position, at least a part of the cover is positioned on an upper side of the plate so as to be contactable with the plate, and wherein the at least a part of the cover comprises a first protrusion which, in the state in which the cover is in the closed position, protrudes in the feeding direction and is positioned on the upper side of the plate so as to be contactable with the plate: characterised in that: the cover comprises an edge portion positioned opposite to the first protrusion relative to the first axis, in a state in which the cover is in the open position, at least a part of the plate is positioned on an upper side of the edge portion of the cover so as to be contactable with the edge portion, and in the state in which the cover is in the open position, the edge portion is lower than a protruding end of the first protrusion. the cover comprises an edge portion positioned opposite to the first protrusion relative to the first axis, in a state in which the cover is in the open position, at least a part of the plate is positioned on an upper side of the edge portion of the cover so as to be contactable with the edge portion, and in the state in which the cover is in the open position, the edge portion is lower than a protruding end of the first protrusion.
