Abstract: A paper feed roll assembly is disclosed which is pivotally mounted on a central point with three degrees of freedom of movement. The feed rolls are engageable with the periphery of the platen. Additionally, the support for the paper feed rolls is deflectable about the central point by a feed roll release member to effect the withdrawal of the feed rolls from the periphery of the platen to enhance paper insertion and removal. The pivot point support provides for freedom of movement in the three necessary degrees of freedom to allow equilization of feed roll force against the platen and for alignment of the feed rolls with the periphery of the platen to insure proper paper feed. The feed roll truck frame, by virtue of its pivotal mounting, may be deflected downward to permit release or insertion of the paper. A deflection means or eccentric bar is disclosed for deflecting the truck member away from the periphery of the platen against the force of the pivot support acting toward the platen.
