Abstract
A paper feeder for printers having front and back pin tractor assemblies disposed on opposite sides of a platen roller with respect to the paper feed route. Each tractor has a plurality of pins which are rotatable so as to convey the continuous paper. A reversible drive source is coupled to both the pin tractors. A clutch selectively decouples the drive source from the front pin tractors in accordance with the rotational direction of the drive source. A switch mechanism independent of the clutch also selectively decouples the front pin tractor from the drive source. The described structure allows paper stack to be automatically removed from between the tractors.
