The top sheet of a stack of sheets of paper is fed therefrom by a relatively low cost feeder. A tray 1 (Fig. 1) has a stack 2 of sheets of paper disposed therein. A wheel 3, which has its shaft 4 (Fig. 2) disposed in vertical slots 5 in parallel walls 6 (one shown) of the tray 1, rides on a top sheet 7 (Fig. 1) of paper of the stack 2. When a solenoid 8, which is mounted on the shaft 4 of the wheel 3, is energized, a rubber tip 9 on the end of a plunger 10 of the solenoid 8 moves the top sheet 7 of paper up an inclined wall 11 of the tray 1 and out of the tray 1 so that one sheet of the stack 2 is fed at a time. The wheel 3 functions as a brake during retraction of the plunger 10 of the solenoid 8 upon completion of feeding of the top sheet 7 of the stack 2 from the tray 1.
