Description

[Detailed explanation of the invention] This invention relates to a pachinko game machine that can completely prevent fraudulent acts against automatic players.In other words, the back part set board attached to the back of the game board covers the entire area of the back of the game board. It is integrally formed with a bottom wall and a pair of side walls facing each other to form a U-shaped cross section and a planar road shape, and the bottom wall has a steel plate facing the back surface of the game board, and the steel plate is the back side of the game board. This invention relates to a pachinko game machine characterized in that substantially all of the automatic rows pivotably mounted on the parts setting board are covered.

In general, fraud prevention devices for automatic rows are attached to automatic rows with a locking mechanism that locks the swing of the automatic row under normal conditions, but releases the lock and allows the automatic row to swing freely when a prize ball is received. However, this device not only has drawbacks such as a complicated structure, requires space for installation, and is high in cost, but also cannot sufficiently prevent fraud, which has become more cunning in recent years.

Therefore, the purpose of the present invention is to provide a pachinko game machine with a simple structure that can completely prevent fraudulent acts from the front side of the pachinko game machine by covering almost all of the automatic rows with a back part setting board and a steel plate. .

Next, the present invention will be explained based on the illustrated embodiment.
Reference numeral 1 denotes a back parts set board made of synthetic resin that is attached to the back surface of the game board 4, and the back surface of the game board 4 is constructed by integral molding over almost the entire area, and 2 is pivotably supported within the back parts set board 1. It is an automatic line with one end facing the lower side of the rectifier 5 so as to be able to receive prize balls, and the other end linked to the opening/closing lever of the prize ball case 6 so as to respond in a related manner. It consists of a vertical rod 2a, and when there is a winning ball, it receives the winning ball from the rectifier 5 and swings.

Reference numeral 3 denotes a steel plate that covers substantially the entire automatic row 2, and the steel plate 3 includes a bottom wall 3a facing the back surface of the game board 4, and a pair of opposing side walls 3b connected to the bottom wall 3a.

3b, the cross section is approximately U-shaped, and the vertical rod 2 of the automatic row 2
It is formed into a planar cross-shaped shape in accordance with the arrangement shape of the horizontal rods 2b and 2b.

In the pachinko machine with the above configuration, the automatic row 2 in the back parts setting board 1 is covered by a steel plate 3, so that the player can drill holes from the front side of the pachinko machine using a drill or a cigarette. Any attempt to tamper with the automatic row 2 will be completely blocked by the bottom wall 3a and side walls 3b, 3b of the steel plate 3.

Therefore, the present invention can prevent fraudulent acts from the front side of the pachinko game machine against the automatic row, and the automatic row of the back parts setting board can be connected to the bottom wall facing the back of the game board and both side walls connected to the bottom wall. It has a simple tank bottom that can be shielded with a steel plate, and has extremely great practical effects, such as being able to be used by easily attaching the steel plate to the back part set board of a conventional pachinko game machine.
