Description

  The present invention relates to a main control board on which a main control circuit for determining whether a game ball passes a start port is determined to be a big hit or a loss, an accommodating member in which the main control board is accommodated, and a main control circuit. The present invention relates to a pachinko machine including a rendering device that performs a predetermined rendering based on a signal output via a control board.

  FIG. 27 is an explanatory front view of a conventional pachinko machine. 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 port 903, a switch for detecting the game ball won in the start port 903 is turned on, and a microcomputer (see FIG. 28 (denoted by reference numeral 701 in FIG. 28) 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.

  FIG. 28 is an explanatory view of a main control board case provided in the conventional pachinko machine 900 shown in FIG. 27, where (a) is a plan view and (b) is a left side view.

  The main control board case 600 is provided on the back surface of the pachinko machine 900. The main control board case 600 includes a case main body 601 whose front is open, and a cover 602 that covers the front of the case main body 601. The case main body 601 is formed in a box shape, and the cover 602 is formed in a flat plate shape. The case main body 601 accommodates a main control board 700 on which a microcomputer 701 is mounted from an opening at the front. The case main body 601 and the cover 602 are fixed by a plurality of one-way screws 603 so that they cannot be opened.

  In addition, an RF tag (also referred to as an RFID tag or an IC tag) 801 is disposed at the boundary between the case main body 601 and the cover 602 so as to straddle the boundary. Further, a seal seal 800 is stuck on the RF tag 801 so as to straddle the boundary between the case main body 601 and the cover 602. The RF tag 801 stores unique identification information for identifying the pachinko machine 900 from other pachinko machines. Further, the RF tag 801 is configured such that when the cover 602 is forcibly opened, the antenna constituting the RF tag 801 is disconnected and communication is disabled. Further, the seal seal 800 is made of paper, and if it is peeled off as it is, it is torn and leaves its trace.

  Then, when the pachinko machine 900 is installed in the pachinko hall, the identification information of the RF tag 801 is read using the RF tag reader, and whether or not the read identification information matches the identification information registered in the RF tag reader in advance. Check that. At this time, if the antenna of the RF tag 801 is damaged, a reading error is notified, so that it is estimated that the cover 602 is opened and the microcomputer 701 may be replaced with an illegal one.

JP 2010-148596 A (22nd-30th paragraphs, FIG. 11)

  However, a clever misconduct was discovered in which the entire main control board case was replaced with an illegal one while the main control board was accommodated, and the jackpot was likely to be illegally generated. The main control board used for this fraudulent act is equipped with a microcomputer with an increased probability of jackpot. Further, the seal seal is peeled off using a special solvent so as not to be broken from the original control board case and so that the antenna of the RF tag is not disconnected, and is re-attached to an unauthorized main control board case.

  For this reason, since the RF tag functions normally, it cannot be found by inspection using an RF tag reader in pachinko halls. Further, since the same main control board case as the original main control board case is used and the same one-way screw is used, it is impossible to detect fraud from the outside.

[Rewriting production control signal]
Next, a configuration for rewriting the checksum signal output from the main control CPU 52 will be described with reference to the drawings. FIG. 20 is an explanatory diagram showing the 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 checksum signal transmitted together with the effect control signal is electrically connected to the communication circuit, and the rewrite circuit 69 is electrically connected to the exchange detection circuit 67. The rewrite circuit 69 includes an MPU 69a that determines whether or not the input signal is a checksum signal and rewrites the checksum signal.

  The main control CPU 52 outputs to the effect control CPU 402 an effect control signal for instructing an effect and a checksum signal indicating a checksum calculated based on the bit configuration of the effect control signal. 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 and the checksum signal are each composed of 8 bits. For example, if the effect control signal is 90H01H (H is a symbol indicating a hexadecimal number), the checksum signal is 91H. The effect control signal and the checksum signal output from the main control CPU 52 are 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 and the checksum signal output from the output buffer 51 a are temporarily stored in the input buffer 405 on the effect control CPU side via the rewrite 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 and the checksum signal stored in the input buffer 405 are input to the input port 403 of the effect control CPU 402.

  Then, the effect control CPU 402 calculates the checksum of the effect control signal input to the input port 403, and the calculated checksum and the checksum indicated by the checksum signal input to the input port 403 are obtained. It is determined whether or not they match. Here, when it is determined that they match, the input effect control signal is analyzed to determine the control target, and the effect control signal is transmitted to the image / audio control board 70, the panel LED relay terminal board 81, and the auxiliary effect drive board according to the determination result. Output to one of 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. Further, the effect control CPU 402 performs error notification when determining that the checksums do not match. For example, an error is displayed on the screen of the effect display 30.

  Further, when the history indicating that the main control board case 57 has been replaced is stored in the storage unit 67b of the replacement detection circuit 67, the rewrite circuit 69 uses the checksum signal input from the output buffer 51a as the check history signal. The checksum signal is rewritten to indicate a checksum having a value different from the checksum indicated by the sum signal. When the checksum signal is rewritten in this way, the error sum described above is performed because the checksum calculated based on the effect control signal input by the effect control CPU 402 does not match the checksum indicated by the checksum signal. It will be.

[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. 21 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 or payout control signal, etc. are executed.

[Production control signal transmission processing]
Next, the contents of the effect control signal transmission process executed by the main control CPU 52 will be described with reference to the flowchart shown in FIG.

  The main control CPU 52 executes an effect control signal transmission process in the game process of S20 (FIG. 21). The main control CPU 52 creates an effect control signal for controlling the effect device at the effect timing for controlling the effect devices such as the effect indicator 30 and the movable accessories 40 to 45 (S21: Yes) (S22). . Subsequently, the main control CPU 52 calculates a checksum based on the bits constituting the effect control signal generated in S22 (S23), and generates a checksum signal representing the calculated checksum (S24). Subsequently, the main control CPU 52 transmits the produced effect control signal and checksum signal to the effect control CPU 402 (S25).

[Checksum signal rewrite processing]
Next, the contents of the checksum signal rewriting process executed by the rewriting circuit 69 will be described with reference to the flowchart shown in FIG.

  When the rewrite circuit 69 receives the effect control signal and the checksum signal transmitted by the main control CPU 52 (S30), the rewrite circuit 69 reads the history data stored in the storage unit 67b of the replacement detection circuit 67 (S31). Subsequently, 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 received checksum signal is checked. The checksum signal is rewritten to a checksum signal having a value different from the checksum indicated by the sum signal (S33).

[Production control signal reception processing]
Next, the contents of the effect control signal reception process executed by the effect control CPU 402 will be described with reference to the flowchart shown in FIG.

  The effect control CPU 402 receives the effect control signal and the checksum signal transmitted from the main control CPU 52 via the rewriting circuit 69 (S40), and calculates the checksum based on the received effect control signal. (S41). Subsequently, the checksum indicated by the checksum signal received in S40 is compared with the checksum calculated in S41 (S42), and it is determined whether or not the two checksums match (S43).

  If it is determined that they match (S43: Yes), control of the effect device indicated by the effect control signal is started based on the effect control signal received in S40 (S44). Moreover, when it determines with not agree | coinciding in S43 (S43: No), an error display is performed on the screen of the production | presentation indicator 30 (S45). For example, the characters “error” are displayed on the screen of the effect display 30. If the checksums do not match, the effect device is not controlled by the received effect control signal.

As described above, when the history of replacement of the main control board case 57 is stored in the storage unit 67b, the checksum signal transmitted from the main control CPU 52 to the effect control CPU 402 together with the effect control signal is rewritten. An error is displayed on the screen of the display 30.
Further, error notification can be performed by outputting a specific sound from the speakers 10 to 12 or lighting or blinking a specific LED.

[Effect of the first embodiment]
(1) As described above, if the pachinko machine 1 according to the first embodiment is used, when the main control board 50 is replaced with the main control board case 57, an error notification is performed. By discovering the machine, it is possible to easily find the pachinko machine in which the fraudulent act has been performed by exchanging the main control board 50 with the main control board case 57. In addition, when the error notification is performed, the rendering device does not operate, and therefore, by discovering a pachinko machine where the rendering device does not operate, the main control board 50 is replaced with the main control board case 57, and an illegal act is performed. A pachinko machine can be easily found.
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 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 main control board 50 is placed in the main control board case in a state where no power is supplied to the pachinko machine 1. When there is an illegal act of exchanging the whole 57, the history of the detection result can be stored and held in the storage unit 67b.

For example, since the history of fraud in which the main control board 50 is replaced with the main control board case 57 can be stored in the storage unit 67b in the stage before being installed in the pachinko hall, the pachinko machine is installed in the pachinko hall. When a pachinko machine is shot, a pachinko machine that has been cheating can be easily found.
Therefore, it is possible to prevent damage caused by fraud before the pachinko machine newly introduced in the pachinko hall is in operation.

(3) Further, even if the main control board 50 is not replaced with the main control board case 57, if the main control board case 57 is slightly lifted from the wall 1c, 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 replacing the main control board 50 with the main control board case 57.

Second Embodiment
Next explained is the second 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. Note that the pachinko machine according to this embodiment has the same configuration and function as the pachinko machine 1 according to the first embodiment except for a part of the electrical configuration, and thus description of the same parts is omitted. In FIG. 25, the backup power supply 67c is omitted.

  On the effect control board 400, an exchange detection circuit 67 including a detection unit 67a and a storage unit 67b is mounted. The payout control board 60 is equipped with a storage unit 67b electrically connected to the detection unit 67a. Each storage unit 67 b is electrically connected to the rewrite circuit 69. The history of the same detection result of the detection unit 67a is stored in each storage unit 67b. When the rewrite circuit 69 receives the effect control signal and the checksum signal transmitted from the main control CPU 52, the rewrite circuit 69 reads the history of detection results stored in each storage unit 67b, and stores the main control board 50 in at least one storage unit 67b. Is stored in the main control board case 57, the received checksum signal is rewritten.

[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.

Therefore, the main control board 50 is exchanged together with the main control board case 57, and further, an illegal act such as deleting the history stored in one storage unit 67b or replacing the storage unit 67b with an illegal one. Even if this is performed, a predetermined error notification can be performed.
Therefore, the main control board 50 can be exchanged together with the main control board case 57, and it is possible to make every effort to find a pachinko machine that has been cheated.

<Third Embodiment>
Next explained is the third embodiment of the invention. FIG. 26 is an explanatory diagram of a switch provided in the pachinko machine according to this embodiment.

  A pair of first conductive portions SW2a is attached to the surface 1d of the wall 1c, and a second pair of first conductive portions SW2a that can short-circuit the pair of first conductive portions SW2a is attached to the surface 56a of the cover 56 that constitutes the main control board case 57. A conductive portion SW2b is attached. The pair of first conductive portion SW2a and second conductive portion SW2b constitute a switch SW2 that detects replacement 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 removed from the wall 1c, 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. Then, the switch SW2 is turned on. When the main control board case 57 is removed from the wall 1c, 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 50 is replaced together with the main control board case 57, the switch SW2 is turned off, and this is detected by the detection unit 67a of the replacement 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 replacement 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 third embodiment of the invention.
Conventionally, the pachinko hall has been damaged by performing an illegal act of replacing the payout control board 60 with the payout control board case 65 with an illegal one so that more prize balls are paid out than the prescribed number. Therefore, the pachinko machine according to the fourth embodiment is intended to prevent the pachinko hall from being damaged by such an illegal act, and the payout control board 60 is replaced with an illegal one together with the payout control board case 65. It is characterized by being able to easily find a pachinko machine.

  Similarly to the main control board case 57, the payout control board case 65 (FIG. 7) is composed of a case body and a cover, and is attached to the surface 1d of the wall 1c formed on the back surface of the pachinko machine 1. A switch SW1 is provided inside the wall 1c with which the payout control board case 65 abuts. The switch SW1 is different from the place where the payout control board case 65 and the main control board case 57 are provided. The replacement detection circuit 67 is electrically connected to a rewrite circuit 69.

The rewrite circuit 69 rewrites the checksum signal that the main control CPU 52 transmits to the payout control CPU 62 together with the payout control signal when the history of replacement of the payout control board case 65 is stored in the storage unit 67b. The
Therefore, when the payout control board case 65 is replaced even once, a predetermined error notification is performed. Therefore, the payout control board 60 is replaced with the payout control board case 57 by finding a pachinko machine in which the predetermined error notification is performed. Thus, it is possible to easily find a pachinko machine that has been cheated. Further, since the prize ball dispensing device 38 does not operate, it is possible to prevent illegal prize balls from being dispensed. The above-described switch SW2 can be used instead of the switch SW1.

<Other embodiments>
(1) The storage unit 67b can be provided at a place where it cannot be visually recognized. For example, when the storage unit 67b is embedded in the game board 5 and the storage unit 67b is taken out, the embedded part of the storage unit 67b is damaged. If this configuration is used, the storage unit 67b cannot be easily replaced, so the history stored in the storage unit 67b is erased, or the storage unit 67b is replaced with an unauthorized one in which no history is stored. Can prevent fraud.

(2) In the first embodiment, the switch SW1 can be configured by an a-contact type switch. With this configuration, the switch SW1 is turned on when the main control board case 57 is not replaced, and is turned off when the main control board case 57 is replaced. The exchange detection circuit 67 detects that the switch SW1 is turned off and stores the history.

(3) In the third embodiment, at least one of the first conductive portion SW2a and the second conductive portion SW2b may be urged in the opposite direction by a biasing member such as a spring. With this configuration, when the main control board case 57 is attached to the wall 1c, it is possible to eliminate poor contact due to the generation of a gap between the first conductive portion SW2a and the second conductive portion SW2b.
The switch SW1 and the switch SW2 may have any configuration as long as it can detect that the main control board case 57 is displaced.

(4) When the history of replacing the main control board case 57 is stored in the storage unit 67b, when the pachinko machine 1 is started, the main control CPU 52 outputs the checksum signal together with the effect control signal to the effect device. At the same time, it can be notified that the history of replacement of the main control board case 57 is stored. For example, a notification LED is provided at a predetermined location of the pachinko machine 1, and the LED is turned on or blinked to notify.
