<p>Sheet feeding apparatus comprising a rotatable feed roll shaft having one feed roll permanently attached at one end and a second axially movably mounted feed roll on the other end of the shaft with a yoke means to axially move the roll. The feeding apparatus is used with a sheet cassette which, when inserted in the sheet supply station, engages positioning means responsive to the insertion of the cassette which thereby automatically positions the movable feed roll so that both feed rolls are positioned substantially the same distance from the sheet edge irrespective of the size of the sheet material. In this manner the sheet feeding apparatus automatically adjusts itself for feeding sheets of various sizes.</p> |
