Therefore, according to the gaming machine of the second aspect, when the control board is exchanged, it is possible to reliably deal with the exchange of the control board.
Even when the main control board is replaced, the abnormality handling process is performed only when the bonus game is won at the time of turning on the power of the spinning machine. Accordingly, it is possible to prevent the RAM of the main control board from being cleared more than necessary.

In addition, as described in claim 3, the power stop information storage means compares the backup power with the reference voltage generated by the power supplied from a power supply different from the power supply that supplies the backup power. A supply stop may be detected.
Further, the abnormality handling process for coping with the replacement of the control board may be the following process.
That is, as described in claim 4 , the abnormality handling process may be a process of clearing data stored in the RAM.

  By doing this, for example, even if a main game board is replaced with another game machine after a big hit or certain change has occurred in a certain gaming machine, the exchange of the main control board is detected and the RAM is cleared. And probability change can be disabled. For this reason, it is possible to prevent a fraud such as exchanging the main control board after a big hit or a probability change has occurred and causing a big hit or the like to occur in a gaming machine at the time of opening a store.

Further, as described in claim 5 , the abnormality handling process may be a process for notifying that the control board has been replaced.
This makes it possible to invalidate the big hit or the probability change by operating a RAM clear switch for clearing the RAM data mounted on the main control board, for example, triggered by the notification.

[Description of operation]
Next, the operation of the pachinko machine 10 will be described.
(1) About the outline of the game of the pachinko machine 10 The pachinko machine 10 of this embodiment is similar to a well-known game machine when the game ball passes through the ordinary electric accessory 36 serving as the first type starting port. The special symbol display device 32 starts the variation display of the special symbol, and after the variation display is finished, the special symbol is determined and displayed according to the lottery result. When the lottery is won, the special symbol display device 32 displays the same special symbols side by side, and the special winning opening 40 is opened and closed for a predetermined number of rounds, and the player is given a special game. A predetermined game value is given.

In addition, when a big hit is made by a specific special symbol, it becomes a well-known probability fluctuation state, and the probability of winning a big hit increases from the end of the special game until the next big win is won. The period during which the accessory 36 is released and the probability that the ordinary electric accessory 36 is released increases, and a gaming state advantageous to the player is achieved. In addition, when it is a big hit by a specific special symbol, you may be comprised so that it may become a known time reduction mode.
(2) Processing at power-on Next, power-on processing performed by the main control board 30 when the power of the pachinko machine 10 is turned on will be described with reference to the flowchart shown in FIG. This process is a process performed when the power of the pachinko machine 10 is turned on and supply of power from the DC 12V power supply of the power supply board 55 to the main control board 30 is started.

  In S105, the one-chip microcomputer 30a of the main control board 30 performs a security check that detects falsification of the game control program stored in the ROM. As a result of the security check, if the game control program has not been tampered with, the process proceeds to S110.

  In S110, the one-chip microcomputer 30a checks whether or not there is a RAM clear signal from the RAM clear switch. If the RAM clear signal is output (S110: Yes), the process proceeds to S135. If the RAM clear signal is not output (S110: No), the process proceeds to S115.

  In S115, the one-chip microcomputer 30a performs a checksum of data stored in the RAM. If there is no abnormality in the data as a result of the checksum (S115: Yes), the process proceeds to S120, and if there is an abnormality (S115: No), the process proceeds to S135.

  In S120, the one-chip microcomputer 30a checks the presence / absence of power stop information based on the signal from the VBB power stop storage circuit 30e, and determines whether or not the power supply from the backup power supply has stopped. Then, the process proceeds to S125.

  In S125, the one-chip microcomputer 30a branches the process depending on whether or not the power supply from the backup power supply is stopped. When the stop of power supply occurs (S125: Yes), the process proceeds to S130, and when the stop of power supply does not occur (S125: No), the process proceeds to S145.

  In S <b> 130, the one-chip microcomputer 30 a determines whether or not a gaming state advantageous to the player such as a probability change state or a time reduction mode has occurred based on data stored in the RAM. If the determination is affirmative (S130: Yes), the process proceeds to S135. If the determination is negative (S130: No), the process proceeds to S145.

  In S135 and S140, the one-chip microcomputer 30a performs stack area setting processing, initializes the RAM work area of the one-chip microcomputer 30a, and then starts normal processing (S150). A game is started.

  In S145, based on the data stored in the RAM, the one-chip microcomputer 30a reproduces the state before stopping the power supply from the DC 12V power supply to the main control board 30, and the normal processing is started (S150). Thereafter, the game of the pachinko machine 10 is resumed from the state before the power supply is stopped.

[effect]
According to the pachinko machine 10 of the present embodiment, when the main control board 30 is removed from the main body of the pachinko machine 10 and the supply of power from the backup power source of the power supply board 55 to the main control board 30 is stopped, the VBB power is stopped. The power stop information is stored in the storage circuit 30e. For this reason, it is possible to reliably detect that the main control board 30 has been replaced by checking the presence or absence of the power stop information. When replacement of the main control board 30 is detected, the RAM of the one-chip microcomputer 30a mounted on the main control board 30 is cleared. Therefore, it is possible to prevent an unauthorized operation such as replacing the main control board 30 after occurrence of a probability change or the like and causing the pachinko machine 10 at the time of opening a store or the like to have a state where the probability change or the like has occurred.

However, the symbol control board 32b, the discharge control board 31 and the like The various control boards may include the same VBB power stop memory circuit. Even in such a case, the same effect can be obtained.

  (2) Moreover, you may provide the VBB electric power stop memory circuit similar to this embodiment with respect to the various control boards mounted in the spinning machine. In such a case, in S130 of the power-on process, it is determined whether or not a bonus game such as a so-called big bonus or regular bonus is established based on the data stored in the RAM, and an affirmative determination is made. In this case, the process may be shifted to S135. Even in such a case, the same effect can be obtained.

  (3) Further, in this embodiment, when the power supply from the backup power supply is stopped and the probability change state is generated, the RAM work area is cleared. Instead of clearing, a warning that the main control board 30 has been replaced may be given by various lamps, speakers 46, or the like. This makes it possible to manually clear the RAM by operating the RAM clear switch, triggered by this warning.

  (4) Further, in the power-on process of the present embodiment, the RAM is cleared when an abnormality of data stored in the RAM is detected by the checksum. However, when an abnormality in the data in the RAM is detected, the RAM may be cleared only when the pachinko machine 10 is in a certain change state or the like.
