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