A paper discharge base 10 is applied with a sponge sheet 84 as a damping plate 78 of an impact wall 70 provided at a paper discharge base 10. A protection sheet 16 is pasted on a surface of the sponge sheet 84. When the damping plate 78 is impacted by print sheet P, the impact force is transmitted from the protection sheet 86 to the sponge sheet 84 and is damped by the sponge sheet 84. Further, the sponge sheet 84 is protected by the protection sheet 86 and therefore, the sponge sheet 84 is not destructed by impact of the print sheet P.
