Abstract
A pin belt type paper tractor comprises a drive shaft rotatively driven at the time of feeding a recording paper, a belt driving wheel fitted slidably in the axial direction on the drive shaft for the rotation therewith, and a chassis body for pinching the belt driving wheel from the opposite sides thereof. The chassis is movable in the widthwise direction of a recording paper and is in engagement slidably at its peripheral portion with a fixed support frame having a length not less than the paper width. A rotary member is rotatably supported by the chassis body and an endless belt is engaged between and around the belt driving wheel and rotary member. The endless belt is provided on its outer peripheral surface with a plurality of pins brought into engagement with the perforations of the recording paper. A paper holding cover is pivotably attached to the chassis body in open and close directions.
