ABSTRACT:
A paper stacking apparatus including a paper stacking device for stacking plural sheets of paper thereon; a paper size detecting device for detecting a size of the paper to be stacked on the paper stacking device; a paper stack detecting device for detecting whether the paper is present or absent on the paper stacking device; and a control device for inhibiting stacking of the paper when the paper size detected by the paper size detecting device is different from a preset paper size, and for allowing the stacking when absence of the paper on the paper stacking device is detected by the paper stack detecting device during inhibition of the stacking. Accordingly, the control device inhibits paper having any sizes other than the preset paper size from being stacked on the top of stacked sheets of paper present on the paper stacking device and restores allowance of stacking when the paper present on the paper stacking device is removed during inhibition of stacking.
