BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates a card-delivering device, especially to a card-delivering device for a shuffling machine to deliver cards smoothly.

2. Description of the Prior Arts

Shuffling machines are widely used in casinos. With reference to FIG. 8, a shuffling machine comprises a shuffler (70), a card input (80) and a card output (90). The shuffler (70) is connected between the card input (80) and the card output (90). Cards are put into the card input (80). The card input (80) delivers the card to the shuffler (70). The shuffler (70) has a controller to drive the shuffler (70) to rotate in a random direction so that the cards are mixed. Then the cards are output from the card output (90).

With further reference to FIG. 9, the card input (80) comprises a frame (81), multiple roller groups (82), a gear group (83) and a slide (84). The frame (81) is connected with the shuffler (70) and has a channel (811). The roller groups (82) are mounted in the frame (81). The gear group (83) is connected to and drives the roller groups (82). The slide (84) slides along the channel (84) and selectively pushes cards to pass through the roller group (82) into the shuffler (70).

However, the slide (84) cannot sift cards one by one and pushes multiple cards in the frame (81) to move toward the roller groups (82). Then more than one card may pass through the roller groups (82) to be delivered into one card slot of the shuffler (70). Therefore, the cards may not be output one by one. Such disordered card output may nullify a card game and cause casinos to lose reputation and customers.

To overcome the shortcomings, the present invention provides a card-delivering device for a shuffling machine to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a card-delivering device for a shuffling machine that precisely delivers cards passing through in order. The card-delivering device has a frame, at least one drawing roller group, a drawing transmission, an actuating roller group and an actuating transmission. The frame has a pivoting panel with a magnet. The drawing roller group is mounted in the frame near the output end. The drawing transmission drives the drawing roller group. The actuating roller group has a magnetic roller corresponding to the magnet. The actuating transmission drives the actuating roller group. When the magnetic roller is rotated, the magnetic roller alternatively attracts or repulses the magnet to cause the pivoting panel to pivot. Therefore, cards pass between the magnetic roller and the pivoting panel in order when a gap between the magnetic roller and the pivoting panel is formed.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
