ABSTRACT:
A paper feeder for a printer having a platen and a tractor feeder which is provided with a pin belt having pins projecting from upper and lower surface of the tractor feeder, and the tractor feeder can be selectively placed either one of a first position in which the paper feeding plane of the paper feeding pins of the lower surface of the tractor feeder aligns with a tangential direction of a lower part of the platen and a second position in which the paper feeding plane of the paper feeding pins of the upper surface is aligned with a tangential direction of an upper part of the platen. Preferably, the tractor feeder can be held at a third position which is intermediate between the first and the second position and a middle plane between the upper and the lower paper feeding plane align with a radial line of the platen. Thus, depending on the position of the tractor feeder, the printing paper can be pulled from the platen, pushed toward the platen or pushed and pulled towards and away from the platen as desired.
