Abstract
A paper stacking apparatus according to an embodiment of the present disclosure includes a stacking table, a first sensor, and a hardware processor. The stacking table includes an upper face on which papers are stacked, the stacking table being capable of being elevated and lowered by a drive mechanism. The first sensor is disposed at a first position and configured to detect the upper face of the stacking table or an upper face of stacked objects stacked on the stacking table. The hardware processor is coupled to the drive mechanism and the first sensor. The hardware processor is configured to determine that the stacking table is excessively elevated when an elapsed time after starting to detect the object by the first sensor is at least a first excessive-elevation determination value of time.
