Abstract

PURPOSE:To change probability of a PACHINKO machine from a distant place by constituting the device so that a signal for specifying a probability mode is transmitted to a game machine specified by a probability mode transmitting means, and the specified game machine generates a random number for executing a great hit operation, under the prescribed probability, based on a signal received by a probability changing means. CONSTITUTION:When the head rank number and the final rack number are inputted from a keyboard 25 by a probability mode change routine, a probability mode number of each rack number is displayed on a CRT 24 screen. Subsequently, when the keyboard 25 is operated and a probability mode number of each PACHINKO rack 41 is inputted, the probability mode number is written as a new probability mode number in a RAM 22. Next, the new probability mode number is outputted to the PACHINKO rack 41 of the selected rack number through a PACHINKO rack selecting circuit 27 and a transmitting/receiving circuit 28. By a CPU of each PACHINKO rack 41, the own rack number is selected, and in the case of a probability mode number transmission processing, the probability mode number is inputted and written in the RAM, and a probability change is executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a probability mode setting device for changing the probability of a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art A conventional pachinko gaming machine that executes a big hit operation is constructed so that a game is played with a certain probability. For example, if the jackpot probability is 1/200, an increment operation is performed every fixed time (for example, 2.048 ms), a random number from 0 to 199 is repeatedly created, and a timing when a game ball wins a specific winning opening. Due to the above, the value of the random number is taken out, and if the value of the random number is, for example, zero, the jackpot operation is executed. By the way, due to technological advances in recent years and revisions to the rules of the Business Act of Customs, etc., it has been admitted that pachinko machines can change the setting of probability mode. This is because one probability mode is selected and stored from a predetermined number of probability modes (for example, three modes of 1/200, 1/220, and 1/240) before the operation of a pachinko parlor, and the selected probability mode is stored. Based on this, the game is executed. As a result, there is an effect that it is not necessary to frequently adjust the nails of each gaming machine on the side of the hall, which contributes favorably to the management of the hall.

[0003]

However, according to this conventional technique, the following problems have been considered. For each gaming machine, after opening the door so that the control board on the back of the main body can be seen from the mounting frame, the control board switch must be operated to change the probability mode setting.
This work is usually performed before opening the business in the morning or after closing the store in the middle of the night, and there was a problem in that it would be extremely burdensome for employees in the hours when the work time is scarce. The stochastic mode setting device of the present invention is made in order to solve the above problems, and is configured as follows.

[0004]

As shown in the basic configuration diagram of FIG. 1, a stochastic mode setting device of the present invention specifies a machine number of a gaming machine in a pachinko hall store, and identifies the machine number of the specified machine number. Probability mode transmitting means (M1) for transmitting a signal for specifying a probability mode number to a gaming machine, and a gaming machine that takes out a random number value due to winning at a specific winning opening and performs a jackpot operation in accordance with the value of the random number. And a probability changing means (M2) for receiving the transmitted signal and generating a random number with a constant probability based on the received signal.

[0005]

The probability mode setting device of the present invention having the above structure transmits a signal for specifying the probability mode number to the gaming machine specified by the probability mode transmitting means (M1), and the specified gaming machine performs the probability changing means. Based on the signal received by (M2), it works to generate a random number that will execute the jackpot operation with a certain probability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments will be described in order to further clarify the structure of the stochastic mode setting device of the present invention.

FIG. 2 shows an island facility of a pachinko game store which is a premise of the present invention, in which a hall computer 2 as a central processing unit provided in a counter 1 centrally manages the store. The flow of pachinko balls in the island facility will be described. In the island facility 3, a plurality of pachinko machines 4i (i
Is a natural number of 1 to n), and one pachinko machine 4i is one for every two pachinko machines 4j (j
Is a natural number of 1 to m), and when the player inserts coins into the automatic coin freight machine 5j, the automatic ball lending machine 5j lends a predetermined number of pachinko balls to the player, and the player can select an arbitrary number. Start a pachinko game on the pachinko machine 4i. The game starts, and the pachinko ball that the player hit on the pachinko machine 4i is temporarily stored in the ball receiving box 6i regardless of whether it is a safe ball or an out ball, and then flows into the ball polishing machine 8 via the collecting gutter 7 Polishing machine 8
After being polished by
Or via the replenishment chute 11i to the replenishment device 12i provided for each pachinko machine 4i. When a safe ball is generated during the game, a predetermined number of prize balls are refunded to the player, and the desired prize is exchanged in the counter 1. The pachinko balls exchanged for prizes are counted by the ball counter 13 and stored in the ball receiving hopper 14, and are returned to the island equipment 3 lacking the pachinko balls via the lifting device 15 and the return gutter 16. . It is possible to easily calculate which island equipment has a shortage of balls by calculating the difference between the number of driven balls and the number of supplied balls by the hall computer 2.
The coins thrown into the automatic ball lending machine 5j are stored in the coin storage box 18 via the belt conveyor 17.

Next, the hall computer 2 will be described. The hall computer 2, as shown in FIG.
A PU 20, a ROM 21, and a RAM 22 are mainly connected to each other by a bus 23 to form a logical operation circuit. The bus 23 has a CRT 24, a keyboard 25,
Printer 26, pachinko machine selection circuit 27, transmission / reception circuit 2
8, the setting switch 29 and the like are connected. As is well known, the pachinko machine selection circuit 27 selects a specific machine from a large number of pachinko machines 3, and the transmission / reception circuit 28 relays data exchange with the selected pachinko machine 4i. As a result, the CPU 20 inputs a pulse signal relating to the number of out balls and the number of safe balls or a signal such as big hit information (fever information) from each pachinko machine 4i, and the difference between the number of out balls and the number of safe balls is constant. When it becomes, it outputs a signal to stop the pachinko machine of a specific model. The power switch 29 has a so-called switching function for switching between a business mode in which the number of out balls and the number of safe balls are input from each pachinko machine 4i and a setting mode in which each initial setting is performed. The setting mode is operated at the position where the key is rotated 90 degrees to the left from the power-off position, and the business mode is operated at the position where the key is rotated 90 degrees to the right from the power-off position.
As a result, when switching from the business mode to the setting mode, the power must be turned off once.

Next, the control board 30 provided on each pachinko machine 4i will be described. As shown in FIG. 4, the control board 30 is configured as a logical operation circuit in which a CPU 30a, a ROM 30b, and a RAM 30c are mainly connected to the external input circuit 30d and an external output circuit 30e by a bus 30f. The external input circuit 30d includes
The hall computer 2 described above, the touch switch 40 that detects that the player is operating the firing handle of the pachinko machine, the ball cutting detection switch 41 that is turned on when there are no game balls in the prize ball payout tank, and the game board surface. Game ball detection switch 4 for detecting that a game ball has entered each winning opening
2-45 etc. are connected. In the external output circuit 30e, a rotary solenoid 46 that shoots a game ball onto the game board surface, and a digital display 47 in which a three-digit numerical pattern fluctuates for a certain time when the game ball wins a specific winning opening on the game board surface , When the digital display indicates "777", the solenoids 48 to 49 used for enlarging the ball entrance for easy entry of the game ball, various lamps 50 to 51 for decorating the game board surface, etc. are connected. ing.

The operation of the present embodiment having the above configuration will be described with reference to FIGS.
It will be described according to the flowchart shown in FIG. The "stochastic mode changing routine" shown in FIG. 5 is executed by the CPU 20 of the hall computer 2, and the "stochastic mode receiving routine" shown in FIG. 6 and the "stochastic changing routine" shown in FIG. 7 are the control base 30 of each pachinko machine 4i. CP
It is executed by U30a. Each of these routines is periodically executed by a method such as a hard interrupt (2.048 ms in this embodiment). It should be noted that each of the processes shown in FIGS. 5 to 7 includes only a routine relating to a process for changing the probability of the pachinko machine 4i among the processes performed by the CPU 20 of the hall computer 2 or the CPU 30a of the control board 30 of each pachinko machine 4i. It is shown.

First, the "stochastic mode changing routine" will be described. This routine is the power switch 2
It is configured so that the shift can be made only when 9 is switched to the setting mode. When this "stochastic mode changing routine" is executed, the time at that time by the built-in timer is stored in the RAM 22, and the totalized data for one day executed after the store is closed is also output when it is output to the printer 26. When the processing executed by the CPU 20 of the hall computer 2 shifts to this routine, a message "Please input the leading serial number" is displayed on the CRT 24 screen (step S100). Here, when the operator operates the keyboard 25 to input the leading serial number (step S110), the message "Please input the final serial number" is displayed (step S120),
When the final serial number is input by the operator (step S
130), the currently selected probability mode number of each model number is displayed on the CRT 24 screen (step S140).
At this time, a message "Please input probability mode number" is also displayed on the same screen (step S150).
When the operator operates the keyboard 25 to input the probability mode numbers of the respective pachinko machines and finishes all the input operations (steps S160 and S170), the probability mode number input subsequently is set as a new probability mode number R
Work for writing to the AM 22 is performed (step S18).
0). The RAM 22 is backed up by a battery so that the written contents are not erased even when the power of the hall computer 2 is turned off. In this embodiment, the changed probability mode number is stored in the battery-backed RAM 22, but it is also possible to use a rewritable ROM. After the above process is completed, a process of outputting a new probability mode number to the pachinko machine of the machine number selected via the pachinko machine selection circuit 27 and the transmission / reception circuit 28 is performed (steps S190 and S200), and this processing is executed. Finish.

Next, the CPU of the control board 30 of each pachinko machine
The "stochastic mode receiving routine" and the "stochastic changing routine" executed by 30a will be described. When the process shifts to this routine, it is first determined whether the own machine number is selected (step S300) or the probability mode number transmission process (step S310). In the process, the probability mode number is input, and the process of writing in the battery-backed RAM 30c is performed, and the process returns to the return (step S320). In the "probability changing routine" shown in FIG. 7, the following processing is performed. In this routine, first, the value of the hit / miss determination random number N is incremented (step S400). This winning / decision determination random number N is read when a game ball enters a specific winning opening on the game board, and its value is read, which is a so-called "big hit" when it is a specific value ("0" in this embodiment). "Execution". The incremented winning / deciding random number N is
Then, it is determined whether the value is 200 or more (step S41).
0), if an affirmative determination that the value is 200 or more is made, it is determined whether the setting mode number is 1 (step S420).
When the probability mode number is not 1, it is subsequently determined whether or not the value of the winning / deciding random number N is 220 or more (step S4).
30). If an affirmative judgment that the value is 220 or more is made, it is judged whether or not the setting mode number is 2 (step S44).
0). When the probability mode number is neither 1 nor 2, it is subsequently determined whether or not the value of the success / failure determination random number N is 240 or more (step S450). If an affirmative judgment with respect to mode 1 is made in step S420, or an affirmative judgment with mode 2 is made in step S440, or an affirmative judgment that the value of the success / failure determination random number N is 240 or more is made in step S450, the process proceeds to step S460. Proceed to and random number N
The value of is cleared to zero and exits to "return". On the other hand, the value of the success / failure determination random number N is 200 in step S410.
Negative determination that the value is less than 220 in step S430, step S45
If the negative determination is made that the value of the random number N is less than 240 in 0, the process directly exits to "return". According to the above-described present routine, when the mode number is 1, the value of the success / failure determination random number N is sequentially and repeatedly updated within the range of “0” to “199” (steps S400 to S42).
0, S460), and when the mode number is 2, the value of the winning / disapproval determination random number N is sequentially and repeatedly updated within the range of “0” to “219” (steps S400 to S440, S460),
When the mode number is 3, the value of the random number N is "0".
To "239" are sequentially and repeatedly updated (steps S400 to S460). As a result, when the mode number is 1, the jackpot probability is 1/200 and the mode number is 2
In case of, the big hit probability is 1/220, and when the mode number is 3, it is 1/240.

According to this embodiment described in detail above,
The variation range of the random number N used for the big hit of each pachinko machine 4i is the keyboard 2 of the hall computer 2.
It has an extremely excellent effect that it can be easily changed by operating 5. As a result, it is possible to preferably eliminate the annoyance of opening the doors and changing the settings one by one so that the respective control boards 30 of the respective pachinko machines 4i can be seen after the pachinko hall is closed as in the conventional case. . Further, the setting change of the hit / miss determination random number N can be executed only in a setting mode in which the number of out balls and the number of safe balls from each pachinko machine 4i cannot be input. Thereby, it is possible to prevent the probability of each pachinko machine 4i from being changed during the operation of the pachinko hall, and to effectively protect the profit of the player. Further, in this embodiment, the power switch 29

According to the stochastic mode setting device of the present invention,
This has the effect of easily changing the probability mode of the gaming machine from a distance. As a result, the annoyance of having to change the setting of the probability mode by operating the switch of the control board after opening the door so that the control board on the back of the main body can be seen from the mounting frame for each gaming machine is preferable. It has an extremely excellent effect of eliminating it.
