The present invention relates to a media stacking apparatus for an automatic media dispenser. The apparatus of the present invention comprises: a roller plate (22) for stacking media by means of the power from a driving source; a power receiving unit (40) for receiving power, engaged with a clutch gear unit (30), said clutch gear unit rotating with the power received from the driving source, wherein the power receiving unit receives power from the clutch gear unit (30) and moves the roller plate (22); and a resilient member (37) for providing resilient force in the direction of the coupling of the clutch gear unit (30) and the power receiving unit (40). When a force from an external source is applied to the roller plate (22), the clutch gear unit (30) of the present invention rotates in the direction of disengagement from the power receiving unit (40) by means of the repulsive force generated in the direction opposite the resilient force, in order to cut off the transmission of power. As described above, the present invention prevents power from being transmitted to the roller plate (22) when a force from an external source is applied, thus preventing gears interposed between a driving motor and the roller plate (22) from being damaged by a force from an external source. |
