摘要： A sheet feeding device includes an inner guide member and an outer guide member that define a sheet feeding path therebetween. The sheet feeding device also includes an engaging member positioned adjacent to one of the inner guide member and the outer guide member, and a receiving portion positioned at the other one of the inner guide member and the outer guide member. The engaging member moves between an engaged position to engage the receiving portion and a disengaged position to disengage from the receiving portion. The inner guide member is selectively connected to the outer guide member via the engaging member and the receiving portion. When the engaging member contacts the sheet in the sheet feeding path, the engaging member is in the disengaged position, and when the engaging member is separated from the sheet in the sheet feeding path, the engaging member is in the engaged position.
