Abstract
A sheet feeding apparatus provided with an urging device to urge the lift shaft, the lift gear or the lift plate in a direction opposite the insertion direction of the sheet feeding cassette, so as to disengage the lift shaft from the lift shaft drive. Insertion of the sheet feeding cassette pushes the lift shaft, lift gear or lift plate against the urging device, thereby engaging the lift shaft with the lift shaft drive. Alternately, rather than employing the urging device, the sheet feeding cassette may pull the lift shaft out of engagement with the lift drive by pulling the lifted lift plate in direction opposite the insertion direction of the sheet feeding cassette.
