Patent attributes
A sheet feeding device includes a stacking member, a feeding unit, and a detachable separation unit. The feeding unit feeds sheets stacked from the stacking member. The separation unit separates the fed sheets one by one. The separation unit includes a rotating member to abut and separate from the feeding unit and to rotate, a biasing member to bias the rotating member toward the feeding unit, and an engaged member to be engaged with an engagement member included in the sheet feeding device. The engagement member can move to a first position where the engagement member is engaged with the engaged member, and a second position away from the engaged member. Where the engagement member moves from the first to the second position when the separation unit is attached to the sheet feeding device, the separation unit moves in a detachment direction using the biasing member.
