In the stacker for successively stacking cut papers therein by inserting a cut paper beneath the previous stacked papers comprising a paper press for pressing the stacked papers from the top surface thereof and a press force switching mechanism for contacting the paper press and applying press force to the stacked cut papers until the stack height of the stacked papers reaches a prescribed value and for releasing the application of the press force when the stack height of the stacked papers exceeds the prescribed value.
