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

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.
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.

The at least one drawing roller group (20, 20A) is mounted in the frame (10, 10A). Each drawing roller group (20, 20A) has a top roller assembly (21, 21A), a bottom roller assembly (22, 22A) and a gap (23, 23A). The top roller assembly (21, 21A) is mounted rotatably between the side panels (13, 13A) near the output end (12, 12A). The bottom roller assembly (22, 22A) is mounted rotatably between the side panels (13, 13A) near the output end (12, 12A) and is mounted adjacent to the top roller assembly (21, 21A). The gap (23, 23A) is formed between the top and the bottom roller assemblies (21, 21A, 22, 22A), aligns with the receiving panel (14, 14A) and allows one card to pass through.
The drawing transmission (30, 30A) is connected to and drives the at least one drawing roller group (20, 20A) and has a motor (31, 31A), a drive gear (32, 32A) and a driven gear set (33, 33A). The motor (31, 31A) is mounted in the frame (10, 10A), may be attached securely to one side panel (13, 13A) and has a driving shaft (311, 311A). The drive gear (32, 32A) is connected to and is driven by the driving shaft (311, 311A). The driven gear set (33, 33A) is driven by the drive gear (32, 32A), is connected to and drives the at least one drawing roller group (20, 20A) and has at least one driven gear (331, 331A). Each driven gear (331, 331A) is driven by the drive gear (32, 32A) and is connected to and drives a corresponding drawing roller group (20, 20A).
In one preferred embodiment, each driven gear (331) engages the drive gear (32). The driven gear (331) is connected to and drives the bottom roller assembly (22) of the corresponding drawing roller group (20)
In another preferred embodiment, a transmitting gear (332A) engages and is connected between the driven gear (331A) and the drive gear (32A) so that the drive gear (32A) drives the driven gear (331A) through the transmitting gear (332A). The driven gear (331A) is connected to and drives the top roller assembly (21A) of the corresponding drawing roller group (20A).
The actuating roller group (40, 40A) is mounted in the frame (10, 10A) and has a central rod (41, 41A), a magnetic roller (42, 42A) and multiple auxiliary rollers (43, 43A). The central rod (41, 41A) is mounted rotatably between the side panels (13, 13A) near the input end (11, 11A). The magnetic roller (42, 42A) is mounted securely around the central rod (41, 41A) and corresponds to and alternatively attracts or repulses the magnet (16, 16A). The auxiliary rollers (43, 43A) are mounted securely around the central rod (41, 41A).
The actuating transmission (50, 50A) is connected to and drives the actuating roller group (40, 40A) and has a motor (51, 51A), a drive gear (52, 52A) and a driven gear (53, 53A). The motor (51, 51A) is mounted in the frame (10, 10A), may be attached securely to one side panel (13, 13A) and has a driving shaft (511, 511A). The drive gear (52, 52A) is connected to and is driven by the driving shaft (511, 511A). The driven gear (53, 53A) engages the drive gear (52, 52A) and is connected to and drives the central rod (41, 41A) of the actuating roller group (40, 40A). When the actuating transmission (50, 50A) drives the central rod (41, 41A) of the actuating roller group (40, 40A) to rotate, the magnetic roller (42, 42A) is rotated to selectively attract or repulse the magnet (16, 16A) and the pivoting panel (15, 15A) is pivoted by the attraction or the repulsion.

With the cooperation between the magnetic roller (42, 42A) and the magnet (16, 16A), the cards placed on the pivoting panel (15, 15A) are delivered one by one toward the drawing roller group (20, 20A). Therefore, the cards are delivered into the shuffler (60) one by one and are delivered out of the card output one by one.
