A conventional pachinko machine 900 includes a launch handle 901, a game board 902, a start port 903, an effect display 904, and a variable winning device 905. When a game ball launched by the player operating the launch handle 901 wins the start opening 903, a switch for detecting the game ball won in the start opening 903 is turned on, and a microcomputer (see FIG. 27 (denoted by reference numeral 701 in FIG. 27) is a big hit or lost decision (hereinafter referred to as a big hit decision).

  Then, the effect display unit 904 starts a variable display (also referred to as scroll display) of a plurality of symbols. For example, an array of symbols (hereinafter referred to as symbol rows) representing consecutive different numbers (for example, 0 to 9) is moved from the top of the screen to the bottom in the ascending order of the numbers in the three horizontal display areas on the screen. To display. Depending on the model, the screen is displayed so as to move from the right to the left of the screen. Hereinafter, the display mode of such a symbol row is referred to as symbol variation display.

  When a predetermined time elapses after the effect display 904 starts displaying the symbol, the symbol variation display stops in each display region, and the symbol corresponding to the determination result by the microcomputer 701 is displayed in each display region. Confirmed display. For example, if the lottery result is a big hit, a big hit symbol consisting of the same number such as “777” is fixedly displayed, and if the lottery result is a loss, a lost symbol such as “767” is fixedly displayed. . The fixed display is a display state in which the symbol indicating the result of the jackpot determination is fixed, and is a display state in which the symbol does not change again.

  When the effect display 904 confirms and displays the big hit symbol, a big hit occurs, and the variable winning device 905 opens the opening / closing member 906 to open the big winning opening 907. Since the large winning opening 907 has an opening area larger than that of a normal winning opening, winning becomes easy. Then, a condition that a specified number (for example, 10) of game balls wins the prize winning opening 907 or a condition that the opening time of the prize winning opening 907 reaches a prescribed time (for example, 30 seconds) is satisfied. Then, the opening / closing member 906 is closed and the special winning opening 907 is closed.

  Then, a round from the opening to closing of the special winning opening 907 is defined as one round, and a plurality of rounds (for example, a maximum of 14 rounds) are executed, during which the player can acquire a large amount of winning balls. Hereinafter, games from the first round to the final round are referred to as jackpot games. In addition, when a big hit occurs in a specific jackpot symbol, the gaming state after the big hit game based on this big hit is changed to a gaming state with a high probability of jackpot occurrence. Such a change in the probability of jackpot occurrence from a low probability to a high probability is called probability change. In the following, the big hit where the probability change occurs is called the probability change big hit, and the big hit other than the probability change big hit is called the normal big hit. In addition, a gaming state that has changed to a certain probability is called a certain probability gaming state. This probabilistic gaming state continues until the next jackpot occurs.

[Flow of control commands]
Next, the flow of control commands output by the main control CPU 52 will be described with reference to the drawings. FIG. 21 is an explanatory diagram showing a hardware configuration of the interface between the main control CPU 52 and the effect control CPU 402.

  The main control CPU 52 and the effect control CPU 402 are electrically connected via a communication circuit (for example, a serial communication circuit). In addition, a rewrite circuit 69 for rewriting the effect control signal is electrically connected to the communication circuit, and the rewrite circuit 69 is electrically connected to the opening detection circuit 67. The rewriting circuit 69 includes an MPU 69a that determines whether or not the input signal is an effect control signal and rewrites the effect control signal.

  The main control CPU 52 outputs an effect control signal instructing the effect to the effect control CPU 402. For example, the main control CPU 52 outputs to the effect control CPU 402 an effect control signal for instructing display of the variation pattern of the effect symbol determined by lottery. In this embodiment, the effect control signal is composed of 8 bits, and is represented by 90H01H (H is a symbol indicating a hexadecimal number), for example. The effect control signal output from the main control CPU 52 is temporarily stored in the output buffer 51a on the main control CPU side from the output port 52a of the main control CPU 52.

  Subsequently, the effect control signal output from the output buffer 51 a is temporarily stored in the input buffer 405 on the effect control CPU side via the rewriting circuit 69. The transfer signal output from the output port 52b of the main control CPU 52 is input to the input port 404 of the effect control CPU 402 via the output buffer 51b on the main control CPU side and the input buffer 406 on the effect control CPU side. Then, it becomes a trigger, and the effect control signal stored in the input buffer 405 is input to the input port 403 of the effect control CPU 402.

  Then, the effect control CPU 402 analyzes the effect control signal input to the input port 403 to determine the control target, and according to the determination result, the effect control signal is transmitted to the image / audio control board 70, the panel LED relay terminal board 81, and the auxiliary. Output to any of the effect drive substrates 500. For example, if the input effect control signal is to control the image of the effect display 30, the effect control CPU 402 outputs it to the image / sound control board 70.

When the history indicating that the main control board case 57 is opened is stored in the storage unit 67b of the opening detection circuit 67, the rewriting circuit 69 uses the effect control signal input from the output buffer 51a as the effect device. Is rewritten to a signal that cannot be controlled.
For example, in the communication arrangement between the main control CPU 52 and the production control CPU 402, the signal is rewritten to a signal that is not decided as the production control signal.

  The main control CPU 52 and the payout control CPU 62 mounted on the payout control board 60 (FIG. 19) are also electrically connected via an input / output buffer and a communication circuit. Then, the main control CPU 52 outputs a payout control signal to the payout control CPU 62 in the same communication procedure as that for the effect control CPU 402 described above.

[Main processing of main control CPU]
Next, main processes executed by the main control CPU 52 will be described with reference to the drawings. FIG. 22 is a flowchart showing the contents of main processing executed by the main control CPU 52.

  The main control CPU 52 executes initial setting when the pachinko machine 1 is activated (S10). In this initial setting, a stack pointer, interrupt inhibition, maskable interrupt mode, access permission for the main control CPU built-in RAM, and the like are set. Further, the main control RAM 74 is initialized, and the initial symbol is displayed on the special symbol display device 31 and the normal symbol display device 33, respectively.

  In addition, an initialization command is output to the effect control board 400, the initial effect symbol is displayed on the effect display 30, and the sound effect, the LED, and each movable accessory 40 to 45 are set to the initial state. Also, an initial state designation command is output to the dispensing control board 60, and the dispensing control board 60 is set to the initial state. Further, the counter and timer used for the game are initialized.

  Subsequently, the main control CPU 52 executes a game process (S20). In this game process, a process necessary for the game is executed. For example, winning detection, jackpot determination, determination of variation pattern of special symbol and normal symbol, transmission of effect control signal, etc. are executed.

[Production control signal rewriting process]
Next, the effect control signal rewriting process executed by the rewriting circuit 69 will be described with reference to the drawings. FIG. 23 is a flowchart showing the contents of the effect control signal rewriting process executed by the rewriting circuit 69.

  The rewriting circuit 69 determines whether or not an effect control signal has been input (S30). If it is determined that the effect control signal has been input (S30: Yes), the history data stored in the storage unit 67b of the opening detection circuit 67 is stored. Reading (S31), it is determined whether or not the read data is 1 (S32). If it is determined that the read data is 1 (S32: Yes), the effect control signal transmitted to the effect control CPU 402 is rewritten to a signal that cannot control the effect device (S33).

  Thereby, it becomes impossible to perform various effects such as the display of the effect design and the effect image by the effect indicator 30, the output of sound by the speakers 10 to 12, the lighting of each LED, and the operation of the movable accessories 40 to 45.

That is, when the history of opening the main control board case 57 is stored in the storage unit 67b, it is possible to prevent the game effect from being performed.
Therefore, by discovering a pachinko machine that does not produce an effect even if it is activated, the main control board case 57 is opened, and the main control MPU 61 is set to an unauthorized one whose probability of occurrence of a big hit is set higher than prescribed. It is easy to find a pachinko machine that has been misconducted. In addition, since the game is not established unless the production is performed, it is possible to prevent illegal prize balls from being paid out.

In addition, since the game is not established unless the effect device is operated, it is possible to prevent illegal prize balls from being paid out.

(2) Since the storage unit 67b is provided at a place other than the main control board 50, even if the entire main control board 50 is replaced with an illegal board, the history of detection results by the detection unit 67a. Is stored in the storage unit 67b, the pachinko machine in which the fraudulent act was performed by opening the main control board case 57 can be easily found.

(3) Further, since the detection function of the detection unit 67a and the storage contents of the storage unit 67b are held by the backup power supply 67c, the unauthorized access to open the main control board case 57 in a state where no power is supplied to the pachinko machine 1 When there is an action, the history of the detection result can be stored in the storage unit 67b.

For example, since the history of fraud in opening the main control board case 57 can be stored in the storage unit 67b in the stage before installation in the pachinko hall, the pachinko machine is installed in the pachinko hall and the pachinko machine is tested At this point, it is possible to easily find a pachinko machine that has been cheated.
Therefore, it is possible to prevent damage caused by fraud before the pachinko machine newly introduced in the pachinko hall is in operation.

(4) Further, even if the main control board case 57 is not opened, if one of the case body 55 and the cover 56 is slid evenly with respect to the other, the switch SW1 performs the switching operation, and the history is stored in the storage unit 67b. Therefore, it is possible to detect a trace of opening the main control board case 57.

The history of the same detection result of the detection unit 67a is stored in each storage unit 67b. The rewrite circuit 69 reads the history of detection results stored in each storage unit 67b, and when the history of opening the main control board case 57 is stored in at least one storage unit 67b, the main control CPU 52. Performs a process of rewriting the effect control signal transmitted to the effect control CPU 402 to a signal that cannot control the effect device, so that the effect device does not operate.

[Effects of Second Embodiment]
As described above, if the pachinko machine 1 according to the second embodiment is used, the storage unit 67b is provided on a plurality of substrates and the same detection result history is stored in each storage unit 67b. Even when one substrate provided with 67b is illegally replaced, the history of detection results can be stored in the storage unit 67b provided on another substrate that has not been replaced.

Accordingly, when the main control board case 57 is opened, and an illegal act such as deleting the history stored in one storage unit 67b or replacing the storage unit 67b with an illegal one is performed. Even so, the rendering device can be prevented from operating.
Therefore, it is possible to make every effort to find a pachinko machine that has been cheated by opening the main control board case 57.

<Third Embodiment>
Next explained is the third embodiment of the invention. FIG. 25 is an explanatory diagram showing in block form a part of the electrical configuration of the pachinko machine according to this embodiment.

SW2b is attached. The pair of first conductive portion SW2a and second conductive portion SW2b constitutes a switch SW2 that detects opening of the main control board case 57.

  The first conductive portion SW2a and the second conductive portion SW2b are each formed in a plate shape or a film shape from a conductive material such as copper or gold. In a state where the main control board case 57 is not opened, the first conductive portion SW2a and the second conductive portion SW2b are in contact and electrically connected, and the first conductive portion SW2a is short-circuited by the second conductive portion SW2b, and the switch SW2 is turned on. Further, when the main control board case 57 is opened, the first conductive portion SW2a and the second conductive portion SW2b are separated from each other and become electrically disconnected, and the switch SW2 is turned off.

That is, when the main control board case 57 is opened, the switch SW2 is turned off, which is detected by the detection unit 67a of the opening detection circuit 67, and the detection result is stored in the storage unit 67b.
As described above, the pachinko machine 1 according to the third embodiment has the same configuration as the pachinko machine 1 according to the first embodiment described above, except that the configuration of the switch for detecting the opening of the main control board case 57 is different. Since the function is provided, the same effect as the first embodiment can be obtained.

<Fourth embodiment>
Next explained is the fourth embodiment of the invention.
Conventionally, the pachinko hall has suffered damage by exchanging the MPU 61 for payout control so that more prize balls are paid out than the prescribed number.
