Abstract
There is disclosed herein a forms feed tractor mechanism having a belt with pins and driving elements extending threrethrough. The pins are adapted to engage perforated holes along the edge of a recorded medium. Driver means are provided for rotating the belt and pins and thereby rotate the engaged medium. Also, there is provided a spring tensioner for maintaining tension on the belt. The tractor includes a door which is rotatably snapped fitted into the housing of the tractor and maintained above the plane of the record medium by an extension on the lower surface thereof. The belt and pins are constructed by molding the pins around the belt side so that the belt is below the feeding surface of the tractor mechanism upon which the paper rests.
