Abstract: A card output device for a shuffling machine is mounted adjacent to a shuffling wheel of a shuffling device and has a housing and a stacking assembly, a pushing assembly and three sensors being mounted in the housing. When the sensors sense that there are cards on the stacking assembly, the stacking assembly and the pushing assembly begin to push the cards toward an outlet of the housing and the shuffling device stops pushing the cards out of the shuffling wheel. When there are fewer cards being stacked in the outlet of the housing, the shuffling device begins to push the cards out of the shuffling wheel and into the card output device. Therefore, the cards are not scattered around the outlet of the card output device and keep a desk for playing a card game neat and tidy.
