Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a pachinko game machine equipped with an electric accessory exhibiting a special prize state in which a winning rate is extremely increased according to satisfaction of a predetermined condition. About.

(Prior Art) As an example of this kind of pachinko game machine, a three-digit roulette that starts operating when a specific winning hole is won, and a predetermined winning hole when the roulette stops operating in a specific state. Some of them have an electrical accessory that operates so as to extremely increase the winning rate of the prize.
However, in such a pachinko game machine, it is necessary that the probability of occurrence of the special prize state falls within a predetermined range, and it is preferable that the special prize state occurs at random timing. For this reason, conventionally, for example, by using a random number pattern, control is performed such that the prize state occurrence probability within a fixed reference operation time set relatively long falls within the target range, and the generation timing of the prize state becomes random. That is being done.

(Problems to be Solved by the Invention) However, in the case of the above-described configuration, the special prize state may not be generated for an extremely long period of time, so that the so-called pachinko game machine has a poor so-called patronage and its operation has been reduced. This causes a problem of lowering the rate. On the other hand, in the conventional configuration, setting the reference operating time as a reference when controlling the probability of occurrence of a prize state can be set to be long, so that the probability of occurrence of a prize state can be maintained at a target value and the prize state can be generated at random timing. It is an indispensable condition for controlling the operation so that the above-mentioned problems cannot be solved at all.

The present invention has been made in view of the above circumstances, and an object of the present invention is to control a prize state in which an extremely high prize rate occurs in a relatively short period and at random timing. It is an object of the present invention to provide a pachinko game machine which has effects such as improvement of stickiness.

[Constitution of the Invention] (Means for Solving the Problems) The present invention is directed to a pachinko game machine provided with an electric accessory exhibiting a special prize state in which a winning rate is extremely increased according to satisfaction of a predetermined condition. In such a pachinko game machine, a counting means for counting the number of driven pachinko balls, a storage means storing a plurality of levels of numerical values, and one of the numerical values stored in the storage means are read out. In addition, when a control means for controlling so as to exhibit the prize state when the count result of the counting means reaches a target value determined based on the readout value is provided, the control means is stored in the storage means. The operation of reading the numerical values of the plurality of stages so as to make a round in a random order is repeated.

(Operation) In a state where a game is played on the pachinko game machine, the number of driven pachinko balls accompanying this is counted by the counting means. On the other hand, the control means reads one of the numerical values of the plurality of stages stored in the storage means, and a target value by which the counting result of the counting means according to the game in the pachinko game machine is determined based on the read value. Is reached, the control is performed so that the winning rate of the electric character is extremely high. In this case, the control means is configured to repeat the operation of reading out the numerical values of the plurality of stages stored in the storage means so as to make a round in a random order. State can be controlled to occur in a relatively short period of time and at random timing.

In addition, the occurrence probability of the special prize state as described above is always within a predetermined range because the numerical values of a plurality of stages stored in the storage means are read so as to make a circuit.

(Example) In FIG. 4 showing the overall appearance, a predetermined number of pachinko balls to be provided for prize balls are provided via a ball supply pipe 3 in a tank 2 provided on the upper rear surface of the pachinko game machine 1. Supplied. The ball supply pipe 3 is provided with a safe ball counter 4 which is provided so as to count pachinko balls (hereinafter referred to as safe balls) newly supplied to the tank 2. generates one counting pulse P ₁ each time counting the safe ball fixed number (e.g., 10).

Out ball counter 5 at the lower back of the pachinko game machine 1
The counter 5 is provided so as to count the number of pachinko balls (hereinafter referred to as “out balls”) with respect to the board surface 1a of the pachinko game machine 1.
Generating a single counting pulse P ₂ each time counting 10) out ball. The counting pulse P ₂ and the counting pulse P ₁
Is provided to a pachinko hall central management device (not shown) as a signal serving as a basis for the balance calculation of the pachinko game machine 1.

On the board surface 1a of the pachinko game machine 1, an electric accessory 8 comprising a roulette 6 having a three-digit number sequence and a large winning hole 7
Is provided. The roulette 6 is provided so as to start operating when a pachinko ball wins in a specific winning hole 9 on the board surface 1a, and when a predetermined condition is satisfied, that is, in a specific state where the figures of each digit are aligned. It is configured to switch to a special prize state in which the large winning hole 7 is opened when the operation is stopped. When the state is switched to the special prize state, for example, the large prize hole 7 is closed and closed. When ten pachinko balls are won in the prize hole 7 after the release, the closing operation is performed. Is repeated ten times, and during the period of the special prize state, the winning rate of the pachinko game machine 1 is greatly increased.

In addition, 11 is a normal winning hole provided on the board 1a, 12 is a receiving tray for pachinko balls released from the tank 1 at the time of winning,
Reference numeral 13 denotes an operation dial of a firing device (not shown) for firing the pachinko balls in the tray 12 onto the board surface 1a.

FIG. 1 shows only a portion of the electrical configuration of the pachinko game machine 1 that is relevant to the gist of the present invention.

In the first view, the counting means serving counter circuit 14 is configured to output a numerical signal Sn indicating the number out ball in the pachinko game machine 1 by counting the count pulses P ₂ from the out-ball counter 5 The counting content is initialized when a reset signal Sr described later is received at the reset terminal R. In addition, the electric accessory 8 is operated only when the stop command signal Sc is given from the timing command circuit 15 in a state where the roulette 6 (see FIG. 4) is operated.
The operation is stopped in a specific state in which the numbers of the respective digits of the roulette wheel 6 are aligned, and a special prize state is provided. In other words, when the roulette wheel 6 starts operating in response to the win of the pachinko ball into the specific winning hole 9, the electric accessory 8 does not switch to the special prize state unless the stop command signal Sc is output. is there.

The storage circuit 16 as storage means stores numerical data in a plurality of stages. Specifically, as shown in FIG. 2, for example, twelve types of data from "-2500" to "+2500".
The driving addition value X of the stage (there are two “0”) is stored. The data stored in the storage circuit 15 is read by an arithmetic processing circuit 17 as control means. Hereinafter, the control contents of the arithmetic processing circuit 17 will be described with reference to FIG.

That is, in FIG. 3, after the arithmetic processing circuit 17 performs a series of initialization operations in response to power-on, one of the twelve types of implanted addition values X stored in the storage circuit 16 is randomly processed. (Step a). Next, the target value Y is calculated by adding the driving addition value X read as described above and a preset reference value (for example, "2500"), and the target value Y is stored (step b). Then, the internal counter for counting the number of times of reading is incremented by one step (step c).

Thereafter, it is determined whether or not the count value ΔN of the internal counter has reached “12” (step d). If “NO” is determined here, the target value Y stored in step b is used as the count value of the counter circuit. It is determined whether or not the value has become equal to or larger than the numerical signal Sn from 14 (step e), and a closed loop is formed and the process waits until the determination becomes "YES". When the relationship of Y ≧ Sn is satisfied (“YES” in step e), the timing command circuit 15 is driven to output a stop command signal Sc (step f), and thereafter, a reset signal Sr is output. Then, while giving it to the reset terminal R of the counting circuit 14, the target value Y stored as described above is initialized (steps g and h), and the process returns to step a.

When it is determined "YES" in the step d, that is, when the random reading and storing operation of the driving addition value X is performed 12 times, the internal counter is initialized (step i), and thereafter, Move to step e.

In short, the arithmetic processing circuit 17 reads out one of the plurality of driving addition values X stored in the storage circuit 16 at random, and adds the reference value (2500) to the read numerical value X.
, And when the numerical signal Sn indicating the number of out-balls according to the game in the pachinko game machine 1 has reached the target value Y, the timing command circuit 15
Outputs a stop command signal Sc to switch the electrical accessory 8 to the special prize state. In this case, the driving addition value X is set in 11 steps and 12 types from “−2500” to “+2500”, and the arithmetic processing circuit 17 goes around the driving addition value X in a random order. Since the reading operation is repeated as described above, the special prize state of the electric accessory 8 is generated at random timing in a relatively short period (a period until the number of out balls reaches 5000 even in the longest case). Become.

Further, since the driving addition value X is read out in a random order but in a single cycle, the probability of the winning state of the electrical accessory 8 always falls within a predetermined range.

In the above-described embodiment, the target value Y is obtained by adding the driving addition value X and the reference value. However, a configuration may be employed in which the storage unit stores a plurality of target values in advance. Things.

[Effects of the Invention] According to the present invention, as apparent from the above description,
In a pachinko game machine equipped with an electric accessory exhibiting a special prize state in which a winning rate is extremely increased according to establishment of a predetermined condition,
The above-mentioned prize state can be reliably controlled so as to occur at a relatively short period and at a random timing, and thereby, it is possible to improve the so-called customer attendance and the operation rate associated therewith, and to reduce the probability of occurrence of the prize state. An excellent effect of being able to always be within the predetermined range can be obtained.
