Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fraud prevention system for pachinko gaming machines for preventing fraudulent games using radio waves from a wireless device or the like.

[Prior Art] A pachinko game parlor has a starting winning hole equipped with a starting winning detector within the game area of the game board, and a starting winning opening that is installed inside the playing area based on the detection by the starting winning detector when a prize is won in the starting winning opening. The game ball is converted into a preliminary game state in which it is easy to win a prize, and during the preliminary game state, further game balls are placed inside the game ball on the condition that a special winning detector detects that the game ball has won a prize in the special prize opening inside the preliminary game state. In pachinko machines that are equipped with a variable prize winning device that converts to a special game state that makes it easier to win, games that lead to profits for the player are determined based on detection by detection units necessary for the game, such as a starting prize detector and a special winning detector. There are various pachinko machines installed.

[Problem to be achieved by the invention] However, in the above-mentioned conventional pachinko gaming machine, no countermeasures have been taken against illegal radio waves that generate illegal voltage in the detection circuit of the detection section necessary for the game, such as the starting prize detector. For example, if a player does not commit fraud for fraudulent purposes,
When a radio device is brought close to the starting winning hole and emitting radio waves, a magnetic field (tli field) is created in the detection circuit such as the starting winning detector in accordance with the transmitted signal, and a logic level induced voltage (illicit electromotive force) is generated in the alternating electromagnetic field. Based on the induced voltage, the actuating section malfunctions and transforms the game into a state that is advantageous to the fraudulent player, which may cause an unexpected disadvantage to the game parlor.

In addition, this induced voltage may completely disable the microcomputer that constitutes the accessory control device that controls the game, causing an unexpected disadvantage to the game parlor.

Recently, a problem has arisen in pachinko game parlors in which illegal players using such wireless devices appear, causing great disadvantage, and there is a need to solve such a problem.

This invention was made for the purpose of overcoming these problems.

[Means for Achieving the Achievement of the Problem] The fraud prevention system for pachinko gaming machines according to the present invention includes:
In order to achieve the above-mentioned problems, an external tampering detection means that detects a tampering signal from an external tampering means that generates illicit voltage in the detecting section necessary for the game of the pachinko gaming machine controls the accessory of the pachinko gaming machine. A fraud notification means is installed in a permanent equipment inside a pachinko gaming machine parlor, and is installed in a permanent equipment in a pachinko gaming machine parlor, and is installed in a pachinko game machine parlor, and based on detection of fraud by said external fraud detection means, said fraud notification means is installed in said accessory control device. The configuration is such that an output signal from the accessory control device is transmitted to the management device.

[Effect] A player attempts to gain an unfair advantage by applying an illegal voltage to a detection part necessary for a pachinko machine's start-up prize detector, etc., using an external means of tampering, such as a wireless device. In this case, the fraud signal from the external fraud detection means is detected by the external fraud detection means, and based on the detection, the fraud notification means informs the pachinko game parlor of the fraud. It can be prevented.

In addition, since the external fraud detection means and fraud notification means are installed as permanent equipment within the pachinko machine shop, the pachinko machine's fraud prevention system remains in use even when the pachinko machine is replaced. It won't happen.
