Description

  The present invention relates to a plug removal prevention mechanism that prevents removal of a plug connected to a circuit board provided in a gaming machine such as a pachinko machine.

  Pachinko machines and slot machines (commonly known as “pachislot machines”) are examples of gaming machines that are installed and used in game halls such as pachinko parlors. These gaming machines are played using pachinko balls or medals as game media. Since a certain value is added to the game media, the player plays a game for the purpose of acquiring more game media.

  For example, in a slot machine, when a bonus combination such as a big bonus (BB) or a regular bonus (RB) is obtained during a game, the game machine mode shifts to a game mode in which a large number of medals can be acquired in a short time. For this reason, the player plays the game with the expectation that a bonus combination will be obtained, but the bonus occurrence probability of the bonus combination is managed by a microcomputer inside the gaming machine, and an electronic lottery executed for each game. If you don't win, you won't get.

  By the way, the daily sales of amusement halls are largely influenced by whether or not a large number of customers can be gathered since the opening of the day. Therefore, in some amusement halls, it is often the case that the store clerk operates the gaming machine between the closing of the previous day and the opening of the next day, and adjusts the gaming machine so that it is easy to win a bonus role in the game immediately after the opening. Has been done. For this adjustment, a device called a driving machine is connected to the circuit board of the gaming machine, and an electronic lottery is automatically repeated to establish a bonus combination. A person can easily obtain a bonus combination. However, these acts that create a state in which a bonus role is established regardless of the customer are criminal acts that violate the laws on customs business etc. and the law on the optimization of business (hereinafter referred to as “the law of the law”). is there.

  In order to prevent such criminal acts in advance, there has been a connector having a removal prevention mechanism that prevents the action of removing the plug from the receptacle on the circuit board on the assumption that the driving machine or the like is connected (for example, Patent Documents 1 and 2).

However, since the above criminal acts still remain, as a countermeasure, in the revised Wind Law Enforcement Rules enforced in 2004, fraud countermeasures such as a structure in which traces remain when circuit boards are modified Mandatory for game machine manufacturers, the prevention of criminal acts was strengthened. With this as an opportunity, connectors having a removal prevention mechanism for preventing the plug from being removed from the receptacle on the circuit board have been proposed one after another (see, for example, Patent Documents 3 and 4). These connectors equipped with a removal prevention mechanism are designed to fix the plug to the receptacle on the circuit board so that it cannot be removed.If the plug is removed, it will be attached to the circuit board or its storage case. Traces remain.
