Description

The invention relates to a circuit arrangement for an electrical be driven gaming machine with a credit counter, the status of Throw-in is increased and for every game by the amount of a stake is reduced, with circulating bodies that gain visible through windows Bear rows of symbols at the start of the game by a control device put into circulation and brought to a standstill one after the other, at the end of the game, which occurs after a predetermined playing time, a Scanning device for cash and special game winnings is activated whose Exits via money and special game win lines with the credit counters or connected to a special game counter, with each counter a numerical display belongs.

From the German Offenlegungsschrift 26 44 679 is an electrically be driven slot machine known with a credit counter, the status after inserting money and for every game by the amount of a game use is reduced. In the event of a win, the amount won added to the status of the credit counter, the latter a money includes counter and a special games.

The gaming machine of the type mentioned is also in circulation bodies equipped, which circulated at the start of the game and again be brought to a standstill in order to see a station wagon through the window nation of winning symbols display to the player by comparison  with the winning combinations shown on a winning schedule Type and amount of any profit that may arise give. The inexperienced player finds it difficult to determine the type and amount of the achieved Recognize profit, and he can only profit on the occasion of himself Determine the changing count from the credit counter by subtraction.

The object of the present invention is a circuit arrangement to be specified, which enables a display of the profit achieved in each case.

The object is achieved in that for the direct display of a he a profitable switch to be activated at the end of the game is the number display in its rest position with the associated counter and connects in his working situation with the profit lines.

The circuit arrangement according to the invention makes it possible to Numerical display shows both the balance and the current balance Show profit, first the old balance, then the achieved Profit and finally the new balance appears. As beneficial it can also be seen that no additional ads are required.

A further development of the invention consists in that the profit lines, which carry money or special game signals, according to their type of win are connected to inputs of a first or second OR gate and that the respective switching position of the switch from the initial state of the respective OR gate can be influenced, the occurrence of the Money signal the money win for the first digit display and the occurrence of the Special game signal switches the special game win to the second digit display.

The switch is only activated at the end of the game if the win is different from zero; a profit of zero is not displayed.

A next development provides that for the special game counter associated second digit display an additional switch is provided, the money win signals occurring at a special game counter switched through from zero to the second digit display.  

This circuit enables money winnings to be made otherwise rarely activated digit display for special games when the The status of the special game counter is zero.

A next training is that everyone's profit lines Type of win with parallel inputs (multiples of space) each of a multiplexer are connected that the outputs of the multiplexer and the outputs deliver the time multiplier signals via the switch for the numerical displays and that the numerical displays are each equipped with a demultiplexer.

The transition from multi-space operation to multi-time operation brings a large saving on cables, switches and installation costs.

A further development is that the numerical displays light up organs are assigned that depend on the size to be displayed (e.g. Credit) can be activated via one control logic each, the control logic signals from the switch position of the associated switch processed matching links, and that the light organs Make text fields belonging to the displayed size visible.

This makes it possible to have a specific value for each displayed value Make text readable.  

The invention is described below with reference to one of the drawings illustrated embodiment described in more detail. It shows

Fig. 1 is a block diagram of the circuit arrangement and

FIG. 2 is a circuit diagram of the switch according to FIG. 1.

It should be noted that the circuit diagrams are clearer for reasons of clarity speed limited to the elements necessary for understanding the invention were. Lines have numbers and the other elements have letters as Mark.

A control device A receives an H signal from the credit counter B via line 1 , which is always present at the parallel output “-, 30” when the status of the credit counter B has at least the amount required for a game. Thereupon, the control device A moves three circulating bodies C 1 , C 2 and C 3 via the brake control lines 2, 3 and 4 in order to bring them to a standstill after a predetermined time according to a modifiable program by the player. Finally, the circulating body C 3 is stopped, whereby the end of the game is fixed.

The last locked positions of the three circulating bodies C 1 , C 2 and C 3 are decisive for the profit, as already described in the introduction. The profit is determined by a scanning device D by sensing the detent positions at the end of the game while the circulating bodies are stationary. The money winning signals are on a multiple line 5 and special game winning signals on the multiple line 6 , each line being associated with a certain amount of profit. The winning signals go to the credit counter B or the special game counter E , which increases their levels. On the other hand, the winning signals are separated by a kind of OR gate F and G , so that in the event of a win, the output lines 7 and 8 carry an H signal.

In the following it is assumed that the level of the special game counter E is different from zero, so that an H signal is present at its "1 special game" marked parallel output and that at the end of the game a cash gain of, for example, DM 3 is achieved. In the scanning device D , the 3, - route is switched through and a multiplexer H , the parallel inputs of which are connected to the individual gain lines of the multiple 5 , generates at its output on line 9 a time-multiplying signal corresponding to profit. An AND gate I , the inputs of which are connected to the H signal-carrying lines 7 and 10 (line 10 is connected to the parallel output "1 special game"), brings a changeover switch K into the working position and thus switches the 3 DM - Corresponding multiplex signal to a first digit display L through. The first numerical display L now shows the profit achieved as long as the circulating bodies C 1 , C 2 and C 3 stand still between two successive games (about 1 sec). If now no new game begins (after pressing a pay button, not shown or with L signal on line 1 ), a switch N is opened in the control device A , so that in any case no profit line can lead to a signal, whereby output line 7 from OR gate F and the output of the AND gate assume the L state and consequently the switch K falls into its rest position, in which it connects the first digit display L to the multiplex output of the credit counter B.

If no profit is achieved at the end of the game, the switch K also remains in the rest position. This excludes the display of a profit of DM 0.00.

With the output of the AND gate I is also connected to a first lighting element M 1 , which when switching the multiplexer H makes a first text field not shown visible, which is associated with the display of the achieved profit.

With the output of the AND gate I is also connected via an inverter O, a second lighting element M 2 , which makes a second not shown text field visible when switching the credit counter B , which is assigned to the display of the credit.

In the following it is assumed that the level of the special game counter is zero. Line 10 then carries an L signal, so that the AND gate I leaves the switch K in the rest position; even if a cash win is achieved, the first digit display L shows the credit. The output of the multi plexer H is connected via line 9 to a second changeover switch P which, in its rest position, connects line 9 to a third changeover switch Q , which in its rest position - analogous to changeover switch K - the special game counter E with a second Numerical display R connects, the balance of special games is displayed. The switch K is due to missing special game credits (line 10 leads L signal) via an inverting input of an OR gate S in its working position, so that the money won on the second numerical display R visible.

In the following it is assumed that a special game and a money win are achieved at the same time. The special game counter E is increased via a Ge win line of the line multiple 6 from the scanner D , so that the money win signal is passed to the first digit display L. The output of the OR gate G carries an H signal, so that it brings the second order switch P directly and the third changeover switch Q via the non-inverting input of the OR gate S into its working position. As a result, the special game winning signal occurring at the output of a second multiplexer T is switched through to the second numerical display and can be read.

From the above description it can be seen that the second digit display R can display three different winnings: credits special games, special game winnings achieved and money winnings achieved. According to the first numerical display L ' can display the two winning sizes, each of which a light element M 1 and M 2 with the profit size associated font fields are assigned to the second numerical display R include three light elements M 3 , M 4 and M 5 , each one make visible from three text fields.

The three changeover switches K, P and Q are shown in FIG. 1 as mechanical contacts. In fact, however, they are electrical switches as shown in FIG. 2. Depending on the control signal at connection 1 , connection is either connected to connection 3 or to connection 4 .

The numerical displays L and K in Fig. 1 receive multiple time signals and a clock from a clock, not shown. A de multiplexer essentially controls the individual light segments of numerical modules.

The individual light segments of the number modules have a common anode. All anodes of the number modules are connected to a line 11 which leads to a first switch U 1 in the control device A. This switch U 1 opens under program control in a certain cycle which is adapted to the game sequence.

The individual light segments M 1 to M 5 are connected at their connections opposite the Anleitlei lines to a common line 12 , which is connected via a second switch U 2 in the control device A , which is operated together with the first switch U 1 , with zero that will.

It should be noted that the control logic for the three lighting elements has been omitted for reasons of clarity. Likewise, the diodes required for decoupling the individual lighting elements M 1 to M 5 when the switch U 2 is opened are not shown.
