<p>PURPOSE:To reduce the size of an equipment by mounting a primary paper integrating feed roller, a secondary paper feed roller and a separating roller on a frame integrally into one unit and axially supporting them so that they can be swung up and down. CONSTITUTION:When a feed signal is turned on, each of rollers 15, 16 and 25 are driven to turn so that sheets of paper are fed one by one from the top according to the rotation speed of the primary feed roller 15, are guided by both a guide belt 30 and a feed-in guide plate 20a and are carried into a nip part between the secondary feed roller 16 and the separating roller 25. At this time, a few sheets of paper P are carried together due to friction force between those sheets, however, the top sheet is carried forth by the rotation force of the secondary feed roller 16 and the rest sheets are carried back toward the tray 1 by the rotation force of the separating roller 25. The carried sheet P is guided by both guide plates 40 and 41 and delivered to a copying section by the rotation forces of transportation rollers 42 and 43.</p> |
