Abstract

See full text

A sheet stacking device includes: a mounting table on which a pallet is mounted, the mounting table having a lift; a sensor including: light emitters and light receivers each arranged in the lateral direction of the sheet stacking device so as to face with each other, the sensor to detect at least one of an upper surface of sheets stacked on the pallet or an upper surface of the pallet; and circuitry configured to cause the lift to lower the mounting table by a predetermined amount in response to the sensor detecting the at least one of the upper surface of the sheets or the upper surface of the pallet, and to determine that the sheets have been stacked abnormally when the sensor is not in a non-detection state after the mounting table has been lowered by the predetermined amount.
