EXITING PAPER DEFLECTOR APPARATUS FOR AN IMAGE REPRODUCTION MACHINE An image reproduction machine has an outlet opening through which successive image-imprinted paper sheets are forwardly discharged by a spaced series of exit roller sets. The discharged sheets are delivered into an open-topped housing well area having a horizontal bottom surface with a back edge forwardly and downwardly offset from the outlet opening, and a ramped surface extending downwardly and rearwardly from the horizontal surface back edge. A deflector bar adjacent the outlet opening has first downwardly projecting portions that engage each discharging sheet and temporarily corrugate and stiffen it in a manner assuring that its front end portion will forwardly clear the rear horizontal surface edge before bending down to its level. These downwardly projecting portions are interdigitated with the exit roller sets and positioned to perform their temporary corrugation function without crinkling the discharging sheets. The deflector bar is also provided with second downwardly projecting portions that function, as the stack nears its maximum height, to cause each successive discharging sheet to engage the previously discharged sheet in a manner forwardly advancing and staggering the uppermost sheets. This reduces the effective stack height adjacent the outlet opening to thereby permit a greater number of discharged sheets to be stacked in the well before the stack blocks the external sheet discharge path. A notch in the deflector bar serves to receive and protect the pivoted paper output sensor portion of the machine as the stack is removed from the well.
