Abstract
A device for mounting a paper tractor assembly between the side frames of a computer printer which allows the entire paper tractor assembly to be "popped out" by the application of finger pressure alone, and which eliminates the cost of rounding the ends of the square drive rod of the paper tractor assembly. The mounting device consists of mounting brackets to secure the rods of the paper tractor assembly, bushings to engage the ends of the square drive rod and adapt them to fit into the mounting brackets, and springs or other resilient means to allow the paper tractor assembly to be "popped out."
