2. Description of the Related Art Most game machines such as pachinko machines, pinball game machines, smart ball game machines and the like and slot machines have their game operations controlled by electronic circuits using microcomputers. . Usually, the electronic circuit includes electronic components such as a central processing unit (CPU) for performing general arithmetic control, a storage element (RAM) capable of reading and writing data, and a storage element (ROM) capable of reading only data. Provided. The CPU controls the operation of the accessory of the ball-and-ball game machine and the reel of the slot machine using the RAM and the ROM.

[0003] The jackpot occurrence probability in this type of gaming machine is determined by random lottery. That is, the random number generated by the random number generator is sampled, and the winning mode is determined based on which section of the winning determination table has the sampled random number value. The winning determination table is made up of data for dividing a certain range of random numbers into respective winning modes, and is stored in the ROM. The CPU generates a large hit if the sampled random number value belongs to the section A of the winning determination table, generates a small hit if the sampled random number value belongs to the section B, and generates a small hit if the sampled random number value belongs to the section C. Lost.

The ROM storing such data as the jackpot occurrence probability is detachably attached to the electronic circuit board and can be replaced. By replacing the ROM, it is possible to easily configure control circuit boards of different game models using the same electronic circuit board.

FIG. 8 shows a general pachinko machine 1 having a conventional board case mounting structure. FIG. 8 (a) is a front view of the pachinko machine 1, and FIG. 8 (b) is a rear view thereof. .

A game board 2 is provided inside a front door in front of the pachinko machine 1. A large number of obstacle nails are planted on the game board 2, and a center accessory (not shown) is arranged at the center. When the handle 3 is rotated, the game balls stored in the upper plate 4 are driven into the game board 2. The game balls hit into the game board 2 flow down the board while being hit by the obstacle nails, and are collected from the out port if they cannot enter any of the winning ports.

On the other hand, when the game balls enter the general winning opening, a predetermined number of game balls are paid out to the upper plate 4. Also, when a game ball wins at the starting port provided at the front center, the variable display device provided at the center role starts to rotate. When the variable display device displays a predetermined symbol and stops, a big hit occurs, and the variable winning device (attacker) is opened for a predetermined time or until a predetermined number of game balls are won. Therefore, when a big hit occurs, the player can acquire a large amount of game balls in a short time.

Further, when the variable display device displays another predetermined symbol and stops, the state becomes a probability fluctuation state, and a jackpot is extremely likely to occur. The jackpot occurrence probability in this probability variation state is predetermined in accordance with the combination of symbols stopped and displayed on the variable display device, and is set to a jackpot occurrence probability value that is much higher than in the normal game state.

As described above, in the board case locking structure of the gaming machine according to the present invention, the fixing means for fixing the first fixture to the base is located between the lower case or the second fixture and the base. Therefore, the fixing means cannot be removed unless the locking device is unlocked and the lower case or the second fixing device is moved. Therefore, unless the locking device is unlocked, the first fixing device cannot be removed from the base, and the board case is kept locked between the first and second fixing devices.

Further, since the fixing means for fixing the mounting portion of the third fixing member to the base is located between the first fixing member and the base, the third fixing member is detached from the first fixing member. Unless otherwise specified, it is kept fixed on the substrate. Moreover, the covering portion of the third fixing member covers the fixing means for fixing the second upper case to the second lower case. Therefore, this fixing means cannot be removed unless the third fixture is removed, and the second upper case cannot be removed from the second lower case.

For this reason, by locking the second fixture to the first fixture, the second substrate case can be locked to the base simultaneously with the first substrate case.

At this time, the fixing means for fixing the second upper case to the second lower case is configured to simultaneously fix the second electronic circuit board to the second substrate case, whereby the second substrate is fixed. The second electronic circuit board housed in the case becomes more difficult to remove.
