Paper supply device with multiple cam surfaces and followers

摘要

A paper supply device for reliably delivering sheets of paper one at a time from a stock of multiple sheets even when the leading ends of the sheets are not neatly aligned together. This paper supply device M 1 has a paper insertion part 11 for holding a plurality of sheets of paper S; a rotationally driven supply roller 20 having a fan-shaped profile including a circular arc part 23 and a bowed part 24 ; a pressure member 30 for resiliently urging the paper S to the supply roller 20 surface; a pressure member control mechanism 37 for displacing the pressure member 30 to a position separated from the supply roller 20 when the bowed part 24 is opposite the pressure member 30 ; a separation pad 40 being resiliently urged toward the trailing end of the stacked paper and having a rotating free end that pivots freely to change the angle of contact of the separation pad with the leading edge of the paper S and a pad control mechanism 47 for displacing the separation pad 40 to a position for aligning the ends of the paper S when the bowed part 24 opposes the pressure member 30.
