A paper feeding apparatus for a printing device, comprising a rotational shaft connected through a one way spring clutch to a forward and reverse rotatable driving motor supported by the printing device, feed rollers mounted on the rotational shaft so as to be in pressure contact with the uppermost surface of pieces of printing paper stacked on a holder table, and a coil spring wound around the rotational shaft and supported at one end thereof by a frame for preventing the rotation in the other direction of the rotational shaft induced by the reverse rotation of the driving motor. The holder table is supported by the frame pivotally through an adjusting means utilizing an eccentric shaft.
