<p>PURPOSE:To keep the feeding condition constant in respective first and second paper- feeding parts, even if the device is applied to a cassette tray or to an elevator tray, by setting the variation widths of the vertical movement of paper-feeding means each of which is in contact with the upper surface of the paper sheet and moves up and down in response to the rise of the bottom plate and to the decrease in the amount of the placed paper sheets, so as to be nearly equal. CONSTITUTION:A first paper-feeding part 21 and a second paper-feeding part 22 are provided with paper-feeding means 25, 29 which are in contact with the upper surfaces of paper sheets and move up and down in response to the rise of the bottom plates 23, 27 and to the decrease in the amount of paper sheets for feeding paper sheets respectively, and the variation widths of the vertical movement of the paper-feeding means 25, 29 are set so as to be nearly equal. Further, paper-sheets end parts are arranged in such a way that the distance between the end of the paper sheet housed in a cassette tray and the paper-sheets manipulating means 33 provided in front of the paper-feeding means 25 is nearly equal to the distance between the end of the paper sheet housed in an elevator tray 8 and the paper sheets manipulating means 33 provided in front of the paper-feeding means 29.</p> |
