PURPOSE: A rejector and a stacking device having the same are provided to improve a printing quality by pulling out unnecessary papers in a paper stacking process and enhance the stacking efficiency by automatically pulling out the unnecessary papers without stopping the paper stacking process. CONSTITUTION: A rejector(100) comprises a first base(120), a rotary shaft(125), a rotor(130), loads(141,142,143,144), springs(151,152,153,154), and a gripper(157). The rotary shaft is supported to the first base to be rotated. The rotor is joined to the rotary shaft to be rotated according to a rotation of the rotary shaft. The cam is mounted in the first base to be faced to the rotor. The loads are movable by penetrated the rotor and arranged so that one end part is touched the cam. The spring is arranged in the circumferences of one or more loads between one surface of the rotor and the cam. The gripper is arranged in the other side of one or more loads projected from the other side of the rotor. |
