PAPER MEDIUM STACKING APPARATUS AND THE METHOD THEREOF

摘要

An objective of the present invention is to provide a medium stacking apparatus and a control method thereof, capable of stably stacking the medium by controlling the speed of the medium stacked in a medium stacking space. To achieve the objective, the medium stacking apparatus comprises: a medium detection sensor disposed on an entrance side of a medium stacking space to detect a medium entering the medium stacking space; first and second transport rollers facing each other by interposing a transport path of the medium to transport the medium passing the medium detection sensor; a sheet roller having a plurality of elastic sheets to stack the medium transported by the first and second transport rollers in the medium stacking space; a transport roller drive unit to rotate the first transport roller; a transport roller deceleration means to decrease a rotating speed of the second transport roller; and a control unit to control the transport roller deceleration means to strike a rear end of the medium by the elastic sheets while the rotating speed of the second transport roller is decreased when the medium is detected by the medium detection sensor.
