65 directions for motor-driven gaming devices that all work on the same principle by varying the running time of the symbol carriers, which results in different positions of the symbol carriers. Switches with variable times, which are used in a wide variety of designs, are used to change the runtime. To describe z. B. the German patents 10 54 535 and 10 89 852 eccentric gears for the time variation of cam switches. The German patent document 11 26 904 specifies a switch in which the time variation takes place by scanning balls of different sizes

All of these devices only work properly if the speed of the symbol carriers is constant and the variation times are matched to these speeds. In the serial production of gaming devices it is extremely difficult to achieve perfect dicing with all devices because In manufacturing a whole series of unfavorable influences interacts with external influences such as Temperature fluctuations, voltage fluctuations and influences of an internal nature, such as self-heating of the Device, lubrication, wear and tear and imbalances change the running time of the symbol carrier and the Variation times. This results in changes in the dicing, the preferred positions to be disrupted the symbol carrier and make the devices unusable.

The invention is based on the object of building gaming machines that work as well as possible Have a cubing device that works independently of external and internal influences.

According to the invention, this object is achieved in that the display positions are each one of the symbol carriers by a position transmitter assigned to this symbol carrier and not influenced by the rest of the mechanism is predetermined and the transfer of this position to the symbol carrier is compulsory.

A mechanical embodiment of the gaming device according to the invention is characterized by rladurc ', that the position transmitter contains a cylindrical housing, inside of which non-conductive balls and a Conductive sphere are included, with the total number of all spheres equal to the number of display positions of the symbol carrier, and control, mixing and contact devices are available.

Another embodiment of the invention is characterized in that the position transmitter consists of a electronic device consists of at least one multi-stage ring counter, the number of stages corresponds to the number of positions of the symbol carrier and that of at least one frequency generator is controlled, which is time or frequency varied.

According to a further embodiment of the present invention, there is only one electronic position transmitter present, which is successively switched to each of the symbol carriers.

The advantages achieved by the invention are that it is possible. also in mass production To manufacture gaming machines with one or more symbol carriers for displaying profits and losses, which meet the requirements with regard to the major throwing within the narrow limits of the Frequency distribution in the case of a random occurrence * follow be righteous And those of external and internal Unaffected by influences, these properties are retained unchanged.

The type and shape of the symbol carriers can be changed, and their speed of rotation can be significant can be reduced, resulting in the possibility of building entirely new types of gaming machines.

F i g. 3 the same mechanical position transmitter in side section;

Fig. 4 the basic circuit diagram for the electrical Cooperation between position transmitter, rotary switch and braking device;

F i g. 5 shows a block diagram for an electronic position transmitter;

F i g. 6 the connection of several symbol carriers to an electronic control transmitter.

In Fig. 1, an embodiment with a six-part symbol carrier is shown. The wiper 17 of a six-pole rotary switch 18 is firmly connected to the symbol carrier 50, which is designed as a drum, via the d / ehencie axis 51. The position locking for the symbol carrier 50 consists, in a known manner, of the pawl 7, which engages in one of the bolts 1 to 6 by the action of the spring 8. If the electromagnet 9 is excited, it pulls the pawl 7 upwards and enables the symbol carrier 50 to run.

In Fig. 2 and 3, a mechanical position transmitter is shown, in the cylindrical, fixed housing 52, a transport ring 53 is rotatably mounted. In the transport ring 53 there are just as many radial holes 153 as the position transmitter has positions. A ball 29 or 30 lies loosely in each of the holes 153. The balls 29 are electrically non-conductive. The ball 30 is electrically conductive. All balls 29 and 30 are exactly the same size and weight, regardless of which measure this is achieved. For example, the balls 29 can be made of glass, while the ".uge! 30" is made of aluminum, since both materials have approximately the same specific weight. However, full glass balls 29 can also be combined with a hollow ball 30 made of metal. The number of balls 29 and 30 correspond to the number of positions of the symbol carrier 50. The shaft 54 is firmly connected to a mixer blade Vi and is set in continuous rotation by a drive, for example at 30 rpm 27, which has openings 28 at the top and bottom for the balls to pass through. The transport ring 53 is driven via a slip clutch, in a known design, and makes a significantly lower speed than the mixer blade, e.g. 6 rpm constant rotation of the transport ring 53 and holds it in a defined position in which the balls 29 · ιαΔ 30 between the contact plate 27 and the housing 52 attached There are n sensing contacts 21-26. The ball 30 establishes a conductive connection between the contact plate 27 and the connection 24. The position of the conductive ball 30 in the Steillingsgeber determines, through electrical transmission on the symbol carrier, the associated position of the symbol carrier. If the holding magnet 56 is excited, the side wall rotates with the transport ring 53 in the clockwise direction and the balls 29 and 30 are guided past the upper opening 28 one after the other and fall under their own weight into the interior of the cylinder 27. They are driven by the rotating mixer55 mixed.

If the holes 153 of the transport ring 53 pass the lower opening 28 of the cylinder 27, they fall the balls 29 and 30 one after the other in the holes 153 are brought back into the scanning position. the F i g. 4 shows the forced electrical transmission of the ball position 24 in the position transmitter via the Rotary switch 18 on symbol carrier 50.

If the holder 60 is operated by hand or by the machine, the rotating grinder 17 runs in Position 14 and closes the circuit for the relay 61 via the conductive ball 30 and the contacts 24 and 27. The relay 61 picks up and interrupts the circuit for the electromagnet via its normally closed contact 9, which releases the pawl 7. She falls in and stops the symbol carrier on the bolt 4; It is completely irrelevant how the symbol bearer is formed or how quickly he is moving and whether his movement is smooth or uneven in Fig. 5 is a possible electronically equivalent solution for the mechanical position transmitter according to FIG. 2 as a block diagram shown.

An electronic position transmitter has a noise generator 70 for dicing amplified noise signal via a time constant element and via a Schmitt trigger 71 an astable Multivibrator 72 controls. The pulses of the multivibrator 72 are fed to a multi-stage ring counter 73, which rotates at the frequency of the multivibrator 72. At one point of the ring counter 73 is another Ring counter 74 coupled, which rotates at a frequency that is equal to the multivibrator frequency divided by the number of stages of the first ring counter 73 is ». The outputs of the two ring counters 73 and 74 are over a diode matrix interconnected. The number of racks of the symbol carrier 50 is determined by the Number of stages of the ring counter and is obtained from the product of the number of stages of the two ring counters 73 and 74. The diode matrix is connected to the rotary switch 18. If the switch 60 is operated by hand or actuated by the machine, one of the outputs 31-36 of the diode matrix becomes conductive, e.g. 34th and the rotating wiper 17 closes the circuit for relay 61 via contact 14. The relay picks up and öffriet the circuit for the electromagnet 9 whereby the symbol carrier 50 in the position 4 to Standstill comes.

6 shows the use of an electronic position transmitter for a gaming machine with three Symbol carriers shown. The rotary switches 18 of the three symbol carriers are connected in parallel to the Position transmitter. The grinders 17 of the three different symbol carriers are consecutively over contacts 62, 63 and 64 are connected to relays 61 and thus set the associated symbol carriers of the one after the other via the brake magnets 9 Row style.
