BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 is a schematic bottom view of the apparatus according to the invention;
FIG. 2 is a schematic side sectional view taken in the center line of the apparatus shown on the FIG. 1.

BEST MODE FOR CARRYING OUT THE INVENTION

The bottom view of the apparatus according to the invention is shown on FIG. 1. The apparatus has a gambling table 2 having a half-round form, usual with card games, which is mounted on a frame 1. The gambling table 2 can be of transparent material, for example glass or any known transparent plastic material suitable for this purpose. In the centre of curvature of the half-round form an essentially vertical shaft 3 is arranged, which is secured to said frame 1 of the apparatus.
Under the plate of the gambling table 2 a dealer arm 4 is pivotably mounted to the shaft 3, which is shown on the FIG. 1 in a pivoted position in relation to the symmetry plane, but on FIG. 2—for sake of better understanding —it is shown in the section plane. The dealer arm 4 is extending up to the rim of the half-round gambling table 2. The dealer arm 4 is coupled through a friction gear 46 driven by a drive 45 to the inner surface 47 of a flange mounted to the rim of the half-round gambling table 2. On the inner surface 47 of the flange there is a position sensor (not shown) for sensing the position of the dealer arm 4, by means of which the pivot rotation of the dealer arm 4 around the shaft 3 can be controlled to the desired position.
On the dealer arm 4 a belt-conveyor 41 is mounted. Under the gambling table 2, on the upper side of the dealer arm 4, parallel thereto a horizontal section of the belt-conveyor is extending. The belt-conveyor 41 is guided at the ends of its horizontal section by two guide- pulleys 42, 43. In addition, the belt is looped around a driver drum 44, too. The belt-conveyor 41 consists of two parallel and displaced belt branches.
Along the circumference of the gambling table 2 a multiple of player's fields 21 are provided, which include a window 22 the size of which is matched to the size of the cards 62 used. Next to each of the 22 windows a display 24 is fitted into the plate of the gambling table 2. A data input means, preferably a keyboard 23 belongs to each of the player's fields 21.
On the plate of the gambling table 2, close to the shaft 3 a dealer's field 25 is formed, consists of a window 26 built into the plate of the gambling table 2.
On the dealer arm 4 card lifting devices 48 and 49 are arranged, which are placed to a radial distance in accordance with the distance between the window 22 of the player's field 21 and the window 26 of the dealer's field 25. On the edges 27 of the windows 22 and 26 being on the lower side of the plate of the table permanent magnets 27 are arranged. The holding plates 51 and 52 of the card lifting devices 48 and 49 respectively, are formed with electromagnets.
The lateral distance between the two parallel branches of the belts of the belt-conveyor 41 is at least slightly larger than the width of the holding plates 51 and 52 of the card lifting devices 48 and 49, so the holding plates 51 and 52 can pass between the said parallel branches when lifting the individual 62 cards.
On the dealer arm 4, between the belt-conveyor 41 and the shaft 3 a card handling unit 6 is arranged, having a card magazine 61 in which cards 62 of soft magnetic material, for example of iron plate, are stacked in a staple, one above the other. The card magazine 61 can be moved vertically by a lifting device 64 mounted onto the dealer arm 4. A dealing device 65, which can be implemented as a pusher, is placed between the card magazine 61 and the shaft 3, which is mounted also to the dealer arm 4. The side walls of the card magazine 61 is open towards the dealing device 65 on the one hand and towards the belt-conveyor 41 on the other, so the dealing device 65 can push a card 62 from the card magazine 61 to the belt-conveyor 41 at a respective height.
By the side of the horizontal part of the belt-conveyor 41, near to the card magazine 61 a card identifying sensor 50 is arranged. Each of the cards 62 are provided with an identifying mark.
The drive 45 of the dealer arm 4, the driving drum 44 of the belt-conveyor 41, the card lifting devices 48 and 49, their electromagnets, furthermore the card magazine drive 63, the dealing device 65, the displays 24, the keyboards 23 and the output of the card identification sensor 50 are connected to a computer 7, which controls the recording of the bets, the displaying of the results, the moves of the apparatus, the dealing of the cards and their withdraw, the evaluation and displaying the results in accordance with the rules of the game.
When playing the game the players being at the gambling table 2 can put their bets using the keyboard 23, then the computer 7 directs the dealer arm 4 to pivotably move to each player's place in succession. The card magazine 61 moves vertically by means of the lifting device 64, stops at a random height of a card 62, for which the dealing device 65 pushes a card 62 onto the belt-conveyor 41 through the open side of the card magazine 61. Following this the movement of the belt-conveyor 41 starts, driven by the driving drum 44 and forwards a card 62 to the window 22 of a player, whilst the card identifying sensor 50 reads the data from each card 62 passing in its vicinity and forwards these data to the computer 7. Under the window 22 the card lifting device 48 lifts up the card 62 from the belt-conveyor 41. The lifted card 62, made for example of iron plate, is clamped to the window 22 by means of the permanent magnet 27 arranged on the lower edge of the window 22.
During the dealing of the cards 62 this process repeats with each player's field 21 and with the 25 dealer's field. Finally, the computer 7 evaluates the game on basis of the data received from the card identifying sensor 50 and from the data of the player's fields 21 and displays the results on the displays 24, records and stores the winnings for all players or subtracts the losses from the stored bets belong to each player.
When the game is over, the cards 62 dealt will be picked up and collected by the apparatus in such a manner, that the card lifting devices 48 and 49 rise to the cards 62 clamped by the permanent magnets 27, the electromagnets of the card lifting devices 48 and 49 are activated and detach the cards 62 from the permanent magnets 27, overcoming their attraction force. After having detached the cards 62 the card lifting devices 48 and 49 will descend to their default positions and place the detached cards 62 onto the belt-conveyor 41, hereupon the computer 7 controls electromagnets to switch off and the belt-conveyor 41 carries said card 62 to the card magazine 61.
Having completed this process, the apparatus is ready to a new game.
The dealing of the cards 62 in the given exemplary embodiment can be realized in three different methods in accordance with the program used in the computer 7. In the first mode the drive of the card magazine 63 moves the lifting device 64 to a random position, so a random card 62 being in the card magazine 61 will appear in front of the dealing device 65. In a second mode, while collecting the cards 62 the lifting device 64 moves to a random position for receiving a card 62, so each of the cards 62 get in a random position in the card magazine 63. In a third mode, the former two variants are used simultaneously, that is the card magazine 63 is moved randomly both when dealing and during collecting the cards 62.
For dealing and handling the cards not only the above disclosed card handling unit 6, but several other known card dealing apparatus can be used. One of the several possibilities is to use the solution disclosed in the international patent specification No. WO9604969, which relates to manipulation and dealing cards.
