Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pachinko gaming machine equipped with an accessory related to a big prize opening.

[Technical background of the invention and its problems]

Pachinko gaming machines have multiple winning holes on the game board, and when a game ball that a player hits along the board hits the winning hole, a certain number of prize balls are paid out. There is. It is well known that among these pachinko game machines, there are various machines that are equipped with an LED numeric display or a rotating drum display as accessories, which significantly increases the winning rate of game balls when a specific game state is reached. That is,
In a pachinko game machine equipped with such accessories, when a game ball wins a prize in a specific prize opening in the game board, the display device changes the display, and after a certain period of time or when the player operates a stop switch. , the variable display of the display device is stopped, and when the display state at the time of stopping becomes a predetermined specific display B (for example, 7, 7, 7), the grand prize opening is kept open for a certain period of time. As a result, winnings of game balls can be significantly increased.

By the way, regarding pachinko machines equipped with the above-mentioned accessories, the Amusement Business Control Act stipulates that when the number of game balls entered into the grand prize opening exceeds a certain number, within the time when the grand prize opening is open, Also, the grand prize opening is automatically closed and game balls are not allowed to enter the grand prize opening indefinitely.

However, in conventional pachinko gaming machines, if for some reason the detection circuit that detects the winning of game balls in the big winning hole breaks down, the number of winning balls in the big winning hole will not be the same as specified by the above law. There was a drawback that the grand prize opening would not close even if the number exceeded the number. In addition, in conventional pachinko gaming machines, the management of the gaming hall modifies the detection circuit.
There is a drawback in that the pachinko game machine can be modified so that the grand prize opening does not close even if the number of winnings of game balls into the grand prize opening exceeds the above-mentioned certain number, making it easy to commit fraud. Ta. In order to eliminate such drawbacks, in conventional pachinko gaming machines, for example, in the case of a detection circuit that uses a normally closed contact as a switch to count the number of winnings in the grand prize opening, it is necessary to prevent the circuit from breaking or When a short circuit occurs or the switch is installed in the wrong position, making it impossible to count, this is detected and a signal is generated, which issues an alarm and forcibly closes the grand prize opening.

However, with such conventional pachinko machines, even if there is a malfunction or fraud, the player can continue playing the game, so it is difficult for the player to notice that the grand prize opening is forcibly closed. However, the disadvantage is that the player continues playing the game without realizing it, and the player suffers an unexpected disadvantage.

[Purpose of the invention]

The present invention was made based on the above-mentioned circumstances, and it is possible that the detection circuit that detects the number of winning balls into the open jackpot may malfunction, or that the circuit may be modified to commit fraud. The object of the present invention is to provide a pachinko game machine that can detect this and stop the shooting of game balls when the game ball is in play.

[Summary of the invention]

The outline of the present invention for achieving the above object is that when a specific gaming state is entered, the grand prize opening is opened, and after a certain period of time or when a certain number of game balls enter the grand prize opening, the grand prize opening is opened. In a pachinko game machine that is in a closed state, an abnormality detection means that issues a signal when an abnormality occurs in a counting means for counting the number of winning game balls entered into a grand prize opening, and a game is played upon receiving the signal from the abnormality detection means.
