Description

  The present invention includes a main control board on which a main control circuit for determining whether a game ball passes through the starting port is determined to be a big hit or a loss, and a main control board case in which the main control board is accommodated is sealed with a seal. It relates to a sealed pachinko machine.

  FIG. 20 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 opening 903, a switch for detecting the game ball won in the start opening 903 is turned on, and a microcomputer (see FIG. 21 (denoted by reference numeral 701 in FIG. 21) 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. 21 is an explanatory view of a main control board case provided in the conventional pachinko machine 900 shown in FIG. 20, 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.

  When the pachinko machine 900 is installed in the pachinko hall, the identification information of the RF tag 801 is read using a portable RF tag reader, and the read identification information matches the identification information registered in the RF tag reader in advance. Check whether or not to do. 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, the seal seal is peeled off with a solvent so that the seal seal is not broken and the antenna of the RF tag is not disconnected, and the microcomputer on the main control board is replaced with an unauthorized microcomputer that is likely to generate a big hit. And the fraudulent act of sticking the seal sticker back occurred.
