<p>The invention relates to automatic sheet feed equipment, particularly for use with microfilm aperture cards that permits ready manual insertion of a sheet into the equipment. The sheets are transported on a plate 12 bearing against a register edge 26 and are moved by engagement in the nip between a drive roll 27c and a counter roll 28c. The counter roll is loosely mounted for vertical movement above the plate 12 and the edge of the plate 12 opposite to the edge 26 is unrestricted so that sheets can easily be inserted in the direction of the arrow A. The rolls preferably have polished surfaces and are each chamfered at least on the side away from the edge 26.</p> |
