PROBLEM TO BE SOLVED: To prevent the occurrence of being hitting-beaten by paper, when hitting the paper, even when using a low strength object as a rubber material of a paddle constituting a paddle device. SOLUTION: In this stack device 101, the paddle device 120 is arranged on the upstream side of a stack tray 3. A paddle reinforcing plate 37 is superposably installed on the paddle 36 of a paddle device single body 34 constituting the paddle device 120. Even if the strength of the paddle 36 is lower than the strength of the paper 1, the strength of the whole paddle (the paddle 36 and the paddle reinforcing plate 37) of an overlapping state, is enhanced more than the strength of the paper 1 by adjusting the strength of the paddle reinforcing plate 37 (changing a thickness, a width and a construction material).
