Abstract
A sheet feeding apparatus that can be adjusted to feed various sized sheets includes a fixed paper guide and an adjustable paper guide. A roller in cooperation with a limiting element insures that only a single sheet is drawn from a stack. To prevent uneven feeding and wrinkling, the center of the roller is biased toward the fixed guide from the medial line between the guides when they are separated by a maximum distance. Preferably, the length of the limiting element is shorter than the length of the roller, and when the guides are separated by a maximum distance the medial line between the guides falls along an edge of the limiting means.
