<p>PURPOSE:To take out an original sheet one by one unforcibly from a pile of the originals without resistance, by providing plural rollers different from one another in surface friction coefficient near the end of a movable original placing stand in the sheet feed direction. CONSTITUTION:When piled originals 9 are lifted upward by moving operation lever 90, the end of originals 9 are rubbed slantly with separating roller 25 located under the passage of original placing stand 8, and originals 9 are taken out one by one from the uppermost sheet of the pile of original 9 with upper side feed roller 24. With decreasing of the pile of originals 9, rollers 73-75 are lifted by action of coil spring 87. When plural sheets of originals 9 enter between rollers 24, 25, a lower sheet of originals 9 not in contact with roller 24 is returned into stand 8 with roller 25 having rotary shaft 21 low in friction coefficient, so only one sheet of the uppermost part of the original pile is guided to the position to be photographed. In the case of a sheet from the lowest part of the pile, rollers 73-75 are lowered, rotation of rollers 24, 25 is rendered reverse to said operation.</p> |
