[Detailed description of the invention] The invention is based on the invention by adding a predetermined number of additional balls to the tank for storing prize balls provided at the upper part of the back of each pachinko game machine via a ball supplement device each time the tank becomes empty. The purpose is to maintain the profit margin of the entire pachinko hall at an appropriate level without any troublesome operations. To provide a centralized control device for a pachinko game machine that performs the following functions.

An embodiment of the present invention will be described below with reference to the drawings.

First, in FIG. 1, which schematically shows the state of pachinko game machines 1, ... viewed from the back, 2 is a prize ball storage tank attached to the upper part of the back of each pachinko game machine 1, and 3 is inside this tank 2. This detection switch 3 is configured to detect when there are no prize balls in the tank 2 and turn it on. 4 is each pachinko game machine 1
A supplementary ball passage provided in the upper part, the supplementary ball passage 4 includes a main passage 5 through which game balls for additional balls from a ball supply source flow, and a downward passage from this main passage 5 corresponding to each tank 2. A branch pipe 6 branched to extend to
..., and the supplementary ball device 7 provided in each branch pipe 6, ...
It consists of The above-mentioned ball supplement device 7 includes an electromagnetic solenoid 8
a and a counter 8b, which allows additional balls to pass only when the electromagnetic solenoid 8a is energized, and counts the additional balls passing in this way by the counter 8b, and a numerical signal S indicating the count value. It is configured to output ₈ .

In FIG. 2 showing the electrical configuration, the pachinko game machine 1 includes an output terminal A that generates one pulse for every 10 balls hit, for example. 8 and 9 are counters that respectively count the pulses from the output terminal A, and a numerical signal _S9 indicating the count value corresponds to the number of balls hit in the pachinko game machine 1. Reference numeral 10 denotes a ball exit which is a detection means that sequentially calculates the ratio of the number of batted balls and the number of prize balls of the pachinko game machine 1 (number of prize balls/number of batted balls, ie, ball exit rate) based on the outputs of the counters 8b and 9. The rate detection circuit outputs the select signal Sb from the output terminal Pb when the calculation result, that is, the ball launch rate W is in the relationship of, for example, W≦1.0, and outputs the select signal Sb from the output terminal Pb.
When the relationship W<1.2 holds, the select signal Sc is output from the output terminal Pc, and when the relationship 1.2≦W holds, the select signal Sd is output from the output terminal Pd.
Incidentally, this ball exit rate detection circuit 10 has a clear terminal.
The calculation contents are initialized when the input to CL rises. 11, 12, 13, and 14 are first, second, third, and fourth memory circuits, and these have predetermined reference values N ₁₁ (for example, 100), N ₁₂
(e.g. 200), N ₁₃ (e.g. 300) and N ₁₄ (e.g.
400) are memorized respectively. 15 is the above standard value
A multiplexer that receives N ₁₁ to N ₁₄ as input,
This means that when the select terminal Ea receives a signal, the reference value N ₁₁ is output from the output terminal P, and when the select terminals Eb, Ec, and Ed receive signals, respectively, the reference values N ₁₂ , N ₁₃ , N ₁₄ are output. is selectively outputted to the output terminal P. 16 is a comparator circuit that compares the output signal S ₁₅ (one of the reference values N ₁₁ to _{N 14} ) from the multiplexer 15 and the numerical signal S ₈ from the counter 8b; When the relationship S ₇ ≧S ₁₅ is satisfied, a pulse signal S ₁₆ is outputted and applied to the reset input terminal R of the R-S flip-flop 17. still,
The counter 8b is configured such that its count value is cleared to "0" when the output of the set output terminal Q of the R-S flip-flop 17 is inverted to a high level signal. 18 is a pulse signal S ₁₈ that rises only while the detection switch 3 is turned on.
This is a pulse generation circuit that outputs R-S.
It is applied to the set input terminal S of the flip-flop 17. Reference numeral 19 denotes an amplifier that receives the output from the set output terminal Q of the R-S flip-flop 17, and when it receives a high level signal, it energizes the electromagnetic solenoid 7a to switch the supplementary ball device 7 to an additional ball supply state.

Now, 20 is a calculation means, which will be described below. That is, this calculation means 20 inputs signals indicating the number of winning balls and the number of batted balls from all the pachinko game machines in the pachinko hall, and a data signal S ₂₁ indicating the sales amount from the ball rental machine group 21. Based on that input, the value obtained by subtracting the number of prize balls from the number of balls hit in the entire pachinko hall, that is, the difference (X), is calculated and the value (X') is obtained by converting this into a monetary amount. In addition, the converted amount (X') is calculated from the sales amount (Y) indicated by the data signal _S21 .
The value (Z) after subtracting is calculated as a value that approximates the premium payment amount, and then (Z) / (Y) is calculated, and the calculation result is calculated as the profit rate T of the entire pachinko hall.
(The smaller this profit margin is, the greater the pachinko hall's profit is). Then, when the profit rate T obtained as described above is in a relationship of, for example, T≦0.9, the calculation means 20 outputs a select signal Sa from the output terminal Pa.
When the relationship 0.9<T<1.2 exists, the select signal Sc is output from the select terminal Pc, and 1.2≦
When the relationship is T, the select signal Sd is output from the output terminal Pd. In this case, each select signal Sa, Sd from the calculation means 20 is sent to the multiplexer 15.
The select signal Sc from the calculation means 20 is input to the select terminals Ea and Ed of the gate circuit 2, respectively.
It is input to the gate terminal G of No. 2.

The gate circuit 22 allows signals to pass only when the gate terminal G receives the select signal Sc, and each of the select signals Sb, Sc, and Sd from the ball exit rate detection circuit 10 is transmitted to the gate terminal G. The signals are input via the circuit 22 to select terminals Eb, Ec, and Ed of the multiplexer 15, respectively. Further, the clear terminal CL of the ball exit rate detection circuit 10 is connected to the set output terminal Q of the flip-flop 17.

In FIG. 2, a counter 9, a ball launch rate detection circuit 10, a comparison circuit 16, an R-S flip-flop 1
7. About the pulse generation circuit 18 and amplifier 19 1
Although only the part corresponding to the pachinko game machine 1 of the machine is shown, such a functional part is actually composed of a microcomputer including the calculating means 20, and is installed corresponding to each of the many pachinko game machines. It will be done.

Next, the operation of the above configuration will be explained. Now, if the profit rate of the entire pachinko hall is within an appropriate range, that is, the profit rate T calculated by the calculation means 20 is
If the relationship is 0.9<T<1.2, the arithmetic means 20 outputs the select signal Sc, and the gate circuit 22 is maintained in a signal-passing state. In this state, if the ball launch rate W detected by the ball launch rate detection circuit 10 satisfies the relationship 1.2≦W, in other words, if the ball launch rate of the pachinko game machine 1 is high,
A select signal Sd is output from the ball exit rate detection circuit 10 and is applied to the select terminal Ed of the multiplexer 15.
given to. Therefore, the multiplexer 15
The output signal S ₁₅ from corresponds to the reference value N ₁₄ (400). In such a state, when the detection switch 3 is turned on when there are no prize balls in the tank 2,
A pulse signal _S18 is output from the pulse generation circuit 18, and the R-S flip-flop 17 is set.
A high level signal is output from the set output terminal Q of the R-S flip-flop 17. Then,
The high level signal clears the count value of the counter 8b to "0", and the amplifier 19 energizes the electromagnetic solenoid 8a to switch the supplementary ball device 7 to the additional ball supply state. For this reason, the branch pipe 6
At the same time, the supply of additional balls into the tank 2 is started, and the counter 8b, which has been cleared as described above, begins to count the additional balls. In this way, when 400 additional balls are supplied into the tank 2 and the count value of the counter 8b reaches "400", the relationship S ₈ ≦S ₁₅ is established, and the pulse signal S ₁₆ is output from the comparison circuit 16. Since the R-S flip-flop 17 is reset, the output of the set output terminal Q is inverted to a low level signal, and the electromagnetic solenoid 8a is cut off. The supply of balls is stopped.
Thus, 400 additional balls are automatically supplied into the tank 2 when it is empty. Further, the ball release rate W determined by the ball release rate detection circuit 10 is 1.0<
When the relationship W<1.2 exists, in other words, when the ball launch rate of the pachinko game machine 1 is average, the select signal Sc is output from the ball launch rate detection circuit 10. Select the terminal
Multiplexer 15 received by Ec has reference value N ₁₃
Outputs an output signal _S15 corresponding to (300). Therefore, in this case, when there are no prize balls in the tank 2 and the detection switch 3 is turned on, 300 additional balls are automatically supplied into the tank 2 in the same manner as described above. Furthermore, if the ball launch rate W determined by the ball launch rate detection circuit 10 satisfies the relationship W≦1.0, in other words, if the ball launch rate of the pachinko game machine 1 is low,
The selection signal Sb is output from the ball exit rate detection circuit 10, and the output signal from the multiplexer 15 is
S ₁₅ corresponds to the reference value N ₁₂ (200).
Therefore, in this case, when there are no prize balls in the tank 2 and the detection switch 3 is turned on, 200 additional balls are automatically supplied into the tank 2 in the same manner as described above.

In summary, when the profit margin of the pachinko hall as a whole is within an appropriate range, the number of balls added to tank 2 changes in three stages: 400, 300, and 200, depending on the ball output rate of pachinko game machine 1. be done.

On the other hand, the profit rate T calculated by the calculation means 20 is
When the relationship 1.2≦T occurs, in other words, when the profit rate of the entire pachinko hall falls from the appropriate range, the selection signal is sent from the calculation means 20.
Since the select signal Sd is output instead of Sc,
The gate circuit 22 is held in an off state as soon as the signal passes, and the multiplexer 15, which receives the select signal Sd at the select terminal Ed, outputs an output signal S ₁₅ corresponding to the reference value N ₁₄ (400). Therefore, in this case, when the tank 2 becomes empty, 400 additional balls are automatically supplied to the tanks 2 of all pachinko game machines 1 in the same manner as described above. Also, the profit rate T calculated by the calculation means 20 is
When T≦0.9, in other words, when the profit rate of the pachinko hall as a whole rises from the appropriate range, the selection signal is output from the calculation means 20.
Since Sa is output, the multiplexer 15 which receives this select signal Sa at the select terminal Ea outputs an output signal S ₁₅ corresponding to the reference value N ₁₁ (100). Therefore, in this case, when the tank 2 becomes empty, 100 additional balls are automatically supplied to the tanks 2 of all pachinko game machines 1 in the same manner as described above.

By the way, in general, pachinko game machines have a property that the smaller the number of prize balls in the tank for storing prize balls provided at the upper part of the back of the machine, the higher the probability of balls entering the safe hole. is known both empirically and experimentally. Therefore, according to this embodiment, when the profit rate of the entire pachinko hall falls below the appropriate range, all pachinko game machines 1
Since the number of balls added to tank 2 will be automatically increased to 400, the ball launch rate of each pachinko game machine 1 will decrease, in other words, the profit margin of the pachinko hall as a whole will increase, and the In other words, the number of additional balls for each tank 2 will be automatically reduced to 100 when the profit rate of the entire hole rises above the appropriate range, so that the ball output rate of each pachinko game machine 1 will increase. If this happens, the profit margin of the entire pachinko hall will decrease, and as a result, the profit margin of the entire pachinko hall can be automatically maintained at an appropriate level. In particular, according to this embodiment, when the profit margin of the entire pachinko hall is within an appropriate range, the number of balls added to the tank 2 of each pachinko game machine 1 is changed according to the ball launch rate of each pachinko game machine 1. Therefore, from this aspect as well, it is possible to help optimize the profit margin of the pachinko hall as a whole.

Note that the profit rate T calculated by the calculation means 20 may be obtained by dividing the premium payment amount corresponding to the number of pitches exchanged for the premium by the sales amount.

According to the present invention, as is clear from the above explanation, a predetermined number of additional balls are added to the prize ball storage tank provided at the upper back of each pachinko game machine each time the tank becomes empty. In a centralized control device for pachinko game machines that supplies balls via a ball supplementary device, when the profit margin of the entire pachinko hall is within an appropriate range, the actual ball hitting rate of each pachinko game machine detected from each The number of additional balls is individually controlled by selecting the number of additional balls based on the ball exit rate, and when the profit margin of the entire pachinko hall is outside the above-mentioned appropriate range, the number of additional balls for each game of each pachinko game machine is uniformly increased or decreased. By doing so, it is possible to have the practical effect that the profit margin of the entire pachinko hall, which controls the ball launch rates of all pachinko game machines at once, can be maintained appropriately without any troublesome operations.
