Description

[Detailed description of the invention] This invention is a pachinko game machine that centrally manages a pachinko game machine equipped with a special safe hole that has an extremely higher winning rate than a normal safe hole based on data from the pachinko game machine. This invention relates to a centralized control device for machines.

In recent years, in pachinko game machines, for example, a so-called electric accessory is activated in response to a winning in a predetermined safe hole, thereby extremely increasing the winning rate for a special safe hole provided corresponding to the electric accessory. What is served is served. On the other hand, in pachinko halls, the balance of each pachinko game machine (the difference between the number of balls hit into the pachinko game machine and the number of prize balls given to players by the pachinko game machine) after the end of business or before the start of business. So-called nail adjustments are made based on this. However, in the case of the above-mentioned pachinko game machine equipped with an electric accessory, even though the probability of the electric accessory operating is extremely low, once the electric accessory operates, a large number of prize balls can be won by the electric accessory. Therefore, it is meaningless to adjust the nails simply based on the income and expenditure of the pachinko game machine, and as a result, it has not been possible to properly adjust the nails in the past.

The present invention was developed in view of the above circumstances, and its purpose is to properly adjust the nails of pachinko game machines equipped with special safe holes that have an extremely higher winning rate than regular safe holes. To provide a centralized control device for a pachinko game machine that achieves the following effects.

Generates P ₂ . Reference numeral 6 denotes an electric accessory provided on the board 2a of the pachinko game machine 2, which is driven in response to the winning of a pachinko ball in the safe hole 7, and moves a pair of arms 6a, 6a with a chain double-dashed line for a certain period of time, for example. Expand as shown. Reference numeral 8 designates a special safe hole into which pachinko balls that fall onto the arms 6a, 6a of the electric accessory 6 when the arms 6a, 6a are in the expanded state are guided by the arms 6a, 6a, and enter the ball. The winning rate for this special safe hole 8 is extremely higher than for other safe holes 7, 9, . . . when the electric accessory is driven. 1
0 is the third counter, which is a winning ball counter that counts the pachinko balls that have entered the special safe hole 8, and this counter outputs one counting pulse P ₃ every time one pachinko ball is counted. . Note that 11 is a saucer to which prize balls from the tank 1 are supplied, and 12 is an operation dial of a firing device (not shown) for firing the pachinko balls in the saucer 11 onto the board 2a.

FIG. 2 shows a central management device 13 according to the present invention, which will be described below. In addition, in this FIG. 2, only the parts directly related to the gist of the present invention are shown. That is, 14 is a first counting circuit, which calculates the total number of prize balls indicating a value (total number of prize balls of the pachinko game machine 2) corresponding to the fixed number of the counting pulse _P1 inputted from the first counter 4. Output signal S ₁ . Reference numeral 15 denotes a second counting circuit, which generates a total number of balls driven signal indicating a numerical value (total number of balls driven into the pachinko game machine ₂ ) according to the number of counting pulses P2 inputted from the second counter 5. Output S ₂ . 16
is a third counting circuit, which is the third counter 1
A special prize ball number signal indicating a value corresponding to the number of counting pulses _P3 input from 0 (number of prize balls entered by balls entering the special safe hole 10 of the pachinko game machine 2)
Output S ₃ . 17 is a subtraction circuit to which _the total number of prize balls signal S ₁ and the total number of batted balls signal S ₂ are input, and this circuit calculates the difference between the total _number of prize balls and the total number of batted balls ( That is, the balance (income and expenditure) of the pachinko game machine 2 is calculated one after another, and the calculation result is output as the calculation signal Sa. 18 is a discontinuation setting number storage circuit, which outputs a discontinuation setting signal Sb corresponding to a predetermined discontinuation setting number. 19 is a comparison circuit that compares the calculation signal Sa and the stop setting signal Sb;
This means that when the relationship Sa≧Sb is established, in other words, when the income and expenditure of the pachinko game machine 2 reaches a predetermined number of stops, the stop signal Sc is generated and the pachinko game machine 2 is stopped. Make it. On the other hand, 20 is a calculation circuit which is a calculation means into which the prize ball total number signal S ₁ and the special prize ball number signal S ₃ are input, and this is sent to the special safe hole 8 based on the input signals S ₁ and S ₃ . Calculate the ratio of the total number of winning balls to the winning balls. Specifically, the arithmetic circuit 20 calculates, for example, the ratio between the total number of winning balls that hit the special safe hole 8 and the total number of winning balls that hit the other safe holes 7 and 9,
A ratio signal Sd corresponding to the ratio is output. 2
1 has input terminals P ₁ , P ₂ , P ₃ , and P ₄ respectively with calculation signals Sa,
Total number of batted balls signal S ₂ , total number of prized balls signal S ₁ , ratio signal
This is a memory circuit to which Sd is input, and when a signal is received at its write terminal W, each input terminal
Store inputs for P ₁ , P ₂ , P ₃ , and P ₄ . In this case, the write terminal W of the memory circuit 21
is provided so that the stop signal Sc is inputted via the OR circuit 22, and therefore, when the pachinko game machine 2 is stopped, the income and expenditure of the pachinko game machine 2 at this point, the batted ball Data on the total number, the total number of prize balls, and the ratio of the total number of prize balls to the winning balls in the special safe hole 8 are stored. A key switch 23 generates a data read signal Se when turned on. Although not shown, when this data read signal Se is output, the contents stored in the memory circuit 21 are read out and printed out. It's structured well. At this time, the readout signal Se is also input to the write terminal W of the memory circuit 21. Therefore, if the key switch 23 is turned on after the pachinko hall has closed, it will be possible to read the pachinko game on that business day. It is possible to print out each of the above-mentioned data of the machine 2.
