The winning prize opening unit includes a front member and a rear member attached to the rear surface of the front member. A detection sensor for detecting a game ball that has passed through the winning opening is supported by the rear member.
In recent years, there has been known a new illegal act of so-called large goto. This goto action is a ball detection sensor corresponding to the winning hole by making an illegal ball (bearing ball) made of iron (ferromagnetic material) one size larger than a normal gaming ball into the winning hole of the game board. Intentionally clogging, illegally irradiating electromagnetic waves to the illegal ball, and causing the incoming ball detection sensor to malfunction. The illegal ball is guided to the winning opening using a magnet from the front of the glass door.

In order to prevent such a gore action from being performed on each winning mouth of the winning mouth unit, it is conceivable to mount a magnetic sensor as a fraud detection sensor on the winning mouth unit.
In this case, the magnetic sensor cannot be disposed on the front surface of the front member that can be seen by the player. Therefore, it is conceivable that the magnetic sensor is disposed on the rear member. However, in order to dispose the magnetic sensor on the rear member, the rear member needs to be a dedicated member that can hold the fraud detection sensor. For this reason, the rear member cannot be shared between the prize opening unit having the magnetic sensor and the prize opening unit not having the magnetic sensor, which may increase the cost of the prize opening unit.

  Accordingly, an object of the present invention is to provide a winning slot unit and a ball game machine capable of accurately detecting an illegal act related to a winning slot while suppressing an increase in cost.
