PURPOSE:To enable paper sheets to be reliably separated one by one irrespective of its quality and the size, by a method wherein a friction pad for separating the paper sheets is forced into resilient contact with the paper sheet feeding position of a paper sheet feed roller positioned opposite to a hopper for feeding the paper sheets. CONSTITUTION:An automatic paper sheet feeder C is positioned opposite to a platen 12 on the upper surface of a printer D, and a frame 13, having arms 13a respectively attachable to both sides in an axial direction of the platen 12, is provided with two paper sheet feed parts 14 and 15 and paper sheet discharge parts 16 and 17. In which case, the paper sheet feed parts 14 and 15 are formed with hoppers 14a and 15a, respectively, for charging paper sheets 19, a paper sheet feed roller 18 mounted in a position allowing the paper sheet feed parts to make contact with the surface of the paper sheet 19 in their respective front open positions, and a friction pad 24 for separating the paper sheets pressed by the paper sheet feed roller. This constitution, when the first paper sheet 19 is fed out through rotational friction of the paper sheet feed roller 18, enables reliable catch of the second paper sheet through press friction of the friction pad 24 with the paper sheet. |
