BRIEF DESCRIPTION OF THE DRAWINGSDETAILED DESCRIPTION

On a base plate 1 (FIG. 1), a shuffling storage means 2′ is disposed on a console formed by two legs 9, which shuffling storage means is formed by a rotatably held drum 2. Said drum 2 is connected to two disks 3 via spacers 62 (FIG. 6). The flanges 2″ of the drum 2 are provided with compartment-like slots 69 which are provided for receiving cards.

Said disks 3 are each provided with a circumferential toothing 70. The shuffling storage means 2′ can be driven via a pinion 4 and a toothed pulley 5 which is rigidly connected to the same and are jointly held rotatably in plates 25, and a toothed belt 6 via a second toothed pulley 7 and a motor 8. This motor 8 is triggered via a randomizer and optionally also moves the shuffling storage means 2′ in mutually opposite directions, so that an oscillating movement of the shuffling storage means 2′ can occur.

A reservoir 10 for the for discarded cards 13 is provided which is part of an input apparatus. It comprises a wedge 11 which is rolled off by a roller 12 which is arranged rotatably within the same on an inclined floor of the reservoir 10 against two elastic rollers 14 (FIG. 2). The two rollers 14 are rotatably held in the two plates 25 on a common shaft 28 and can be driven by way of two belt pulleys 26, a toothed belt 29 as well as a belt pulley 27 via a motor 17 jointly with the rollers 15. Two rollers 16 touch the two rollers 15 on the circumference, so that they can be co-rotated by surface friction.

A sensor 24 is provided as a line sensor for recognizing the card symbol of the respectively moved card 13.

The pair of rollers 19 and the pair of rollers 18 which touch the same on the circumference and are each situated on shaft 30 can be driven in the same manner as described above by motor 23.

The two levers 21 are used for the complete insertion of the respectively moved card into a compartment 69 of the shuffling storage means 2′ and are oscillatingly drivable by way of a rod 22 which is swivelably connected with the lever 21 by the axle 34 by way of an eccentric disk 23 disposed on the motor.

Two variants are provided for the card storage means 42, 42′ (FIG. 1, FIG. 4) for the shuffled cards 13, which storage means can optionally be fastened to the base plate 1 and can easily be mutually exchanged.

A receiving means is provided which comprises two alignment pins 100 which are inserted in the base plate 1 and on which a card storage means 42, 42′ for shuffled cards can be inserted. The card storage means 42, 42′ is provided with respective bores 102 in its base. In order to fix the respective card storage means 42, 42′, a screw 101 is provided which engages in a threaded bore 103 of the card storage means 42, 42′.

A receiving means for the card storage means 42, 42′ can also use clip connectors to connect to the card storage means 42, 42′, or a recess can be formed in the base plate 1 into which the card storage means 42, 42′ can be inserted.

The output of cards 13 from the compartments 69 into a card storage means 42, 42′ is performed by means of two swivel arms 35 which are swivelably held in the two legs 9 and are oscillatingly drivable by way of levers 37 and by way of an eccentric disk 38 situated on a motor. Said two swivel arms 35 each carry at their upper ends an inwardly positioned rail 36 (FIG. 3) which grasps the cards disposed in a compartment 69 and conveys them to a nip gap of two grip rollers 40. Said grip rollers 40 are held in the plates 45 and are simultaneously drivable by a motor 41.

The grip rollers 40 convey the respectively moved cards 13 either into the card storage means 42 for the shuffled cards as shown in FIG. 1 for a stack-by-stack removal of the cards 13, or into a card storage means 42′ for a one-by-one removal of shuffled cards.

A card storage means 42 is substantially formed by a U-shaped table 43 in which the cards 13 are deposited in a stack 44. The cards can be removed upwardly by the croupier stack-by-stack if necessary.

The reservoir 42′ according to FIGS. 4 and 4A is provided for a one-by-one removal of cards 13. The cards emerging from the nip gap of the grip rollers 40 enter the card storage means 42′ through a gap 50 which is limited by an oblique downwardly extending wall 49 and a spring-loaded shoe 47. The cards 13, which also include several of the same simultaneously, are pushed between the shoe 47 and the wall 49 or the cards already disposed in the card storage means 42′, with the shoe 47 being pushed back against the force of the spring 48. The shoe 47 slides over an inclined plane of an L-shaped basic body 46. A gap 73 remains between the lower edge of the wall 49 and the L-shaped basic body 46, through which gap cards 13 can be retrieved one-by-one.

As is shown in FIG. 4A, the inclined wall 49 is provided at its lower edge with a centrally arranged recess 72 which is open on its edge and facilitates the withdrawal of the individual cards. The card storage means 42′ is limited on the side by walls 50. The shuffled cards can be retrieved by the croupier individually in that the respectively foremost of the playing cards 13 is grasped through recess 72 in the wall 49 and is pulled through the gap 73.

As is shown in FIGS. 5 and 5A, springs 51, 52 are arranged in the compartments 69 of the shuffling storage means 2′, which springs ensure the clamping of the card(s) inserted into the respective compartment 69.

The spring 52 is provided with a bending 55 which covers the radially outer openings of the compartments 69 and prevents securely that cards are ejected outwardly by centrifugal force during the rotation of the shuffling storage means 2′.

The springs 51 according to FIG. 5A are arranged as curved or bent leaf springs and are inserted in a slot 53 of the one wall of the compartment 69 and press against the respectively opposite wall of compartment 69. The card inserted into the respective compartment 69 is clamped between said spring 51 and the opposite wall of compartment 69 and held in this way in the respective compartment 69.

The output of the cards of a compartment 69 is carried out in such a way that the card 13 or a stack of up to nine cards for example is ejected by force. This is carried out by means of the swivel arms 35 and rails 36, as already explained above. The springs 51, 52 are deformed during the ejection of the card(s) 13.

As is shown in FIGS. 1 and 6, drum 2 rests with axle journals 57 in receiving means of legs 9 and can be removed or lifted from the same with ease. Since the compartments 69 are provided with springs 51, 52, the cards 13 can remain in their compartments during the removal of drum 2.

The drum 2 can be placed in a security container 63 (FIG. 7) and can be transported in the same, with the container 63 being sealable with a lid 64. For this purpose, flanges 65, 66 are fastened on container 63 and the lid 64. This allows connecting the container 63 with the lid 64 in a manner so as to be secure against manipulations or to lock the same.
