Claim:
A feeding device comprising: a body having a first sheet placement surface on which a sheet that is to be fed is placed; a cover rotatably provided at the body, the cover having a second sheet placement surface capable of supporting a back edge portion in a feeding direction of the sheet when the cover is open, the cover being provided with a rotary shaft, the sheet being placed on the first sheet placement surface; a moving member provided at the first sheet placement surface so as to be movable in line with the first sheet placement surface in a direction that is parallel to the feeding direction; a linking member extending in a direction of movement of the moving member from the moving member, one end portion of the linking member being rotatably linked to the moving member using a second rotary shaft that is parallel to the rotary shaft of the cover; and a sheet back-edge regulating member provided at the linking member so as to be movable in the direction of movement of the moving member, the sheet back-edge regulating member regulating a back edge in the feeding direction of the sheet placed on the first sheet placement surface, wherein the first sheet placement surface has a first engaging section extending in the direction of movement of the moving member, wherein the moving member has a first engaging pawl that is capable of engaging the first engaging section, wherein the linking member has a second engaging section extending in a longitudinal direction of the linking member, wherein the sheet back-edge regulating section has a second engaging pawl and an engaging pawl disengaging unit, the second engaging pawl being capable of engaging the second engaging section, the engaging pawl disengaging unit disengaging the second engaging pawl from the second engaging section, and wherein a force that causes the second engaging pawl to engage the second engaging section is stronger than a force that causes the first engaging pawl to engage the first engaging section.
