摘要： A paper feeding device having a pick mechanism which takes out, in order, a plurality of paper sheets put on a chuter starting at the underside and moves them to a specified standby position, comprising a gate (2) formed roughly perpendicular to a sheet advancement direction and forming a specified clearance between it and a pick roller (1), a sheet separating pad (3) which comes into sliding contact with the pick roller (1) and takes in, one by one, the sheets put on the standby position, and a pick arm (4) which can be driven so that, when sheets are set, it is positioned on the upper side and, when they are fed, it is positioned on the lower side so as to press the sheets put on the chuter near a sheet feed port from the upper side, whereby, when a planetary gear (5) is freed by its disengagement from a drive transmission system, the pick arm (4) presses the sheets with a pressing force increasing gradually as the number of sheets put on the chuter is increased.
