  Conventionally, a pachinko machine has been provided with a winning device that can be converted into a state where a large number of winning balls can be obtained in a short time, which is called by a name such as a variable winning device, a variable winning device, or a big winning opening. This winning device (hereinafter referred to as a variable winning device) normally closes the opening / closing member and prevents the game ball from entering the winning opening, but when a predetermined condition is satisfied (big hit), the opening / closing member The game ball is configured to be opened and converted into a state where the game ball can easily enter. For example, in a pachinko machine equipped with a symbol start port and a symbol display device on the game board surface, one big hit random number value is extracted when the launched game ball wins the symbol start port, and the value is determined in advance. Matching the value is the above-mentioned predetermined condition, and when the condition is satisfied, the jackpot symbol is displayed on the symbol display device, and the variable winning device is activated to convert the game ball into a state in which it is easy to enter. . Such a variable winning device that can be converted into a state where a large number of prize balls can be obtained in a short time occupies a large part of the fun of pachinko games.

  However, it is the result of an electric lottery called a random lottery that the floating winning device is activated and the game ball is converted into a state where it is easy to enter, and accordingly, it is necessary to invest accordingly or be lucky. Therefore, a player (Goto) who tries to acquire a prize ball by an illegal operation is forever. And, one of the cheating acts (got act) is to insert a wire or thin plate from the gap between the upper plate panel and the glass frame, etc. There are some which make it easy to enter the winning opening of the winning device and illegally obtain a large amount of winning balls.

Therefore, in order to deal with these frauds, the detection result at the big winning opening that is not a big hit is stored immediately without winning a ball, thereby preventing the ball from being thrown out by fraud, and the back of the pachinko machine A pachinko machine that can be paid out by pressing a switch provided on the payout board is proposed (for example, see Patent Document 1).
