Description

  The present invention relates to a gaming machine provided with a magnetic sensor capable of detecting the magnetism of a magnet.

  A pachinko machine, which is a typical gaming machine, has a gaming board composed of a plate-shaped member having a gaming area defined on the front surface and an installation member disposed on the back side of the plate-shaped member. A frame-shaped decorative member (a so-called center accessory) is disposed at a substantially central position, and a liquid crystal type display device such as a liquid crystal type or a drum type that displays a plurality of symbols on the installation member and performs a symbol variation effect is arranged. It is configured so that the display unit of the symbol display device faces the opening of the frame-shaped decorative member from behind, and the effect executed on the display unit through the opening is visible from the front side. In addition, a start winning device that starts fluctuations in the symbol display device by winning a pachinko ball (game ball) or a special winning device that opens at the time of a big hit is disposed below the frame-shaped decorative member in the plate-like member. A number of such configurations have been proposed. In this type of pachinko machine, the pachinko ball launched into the game area gradually flows down by its own weight while bouncing off by contact with a game nail or the like planted in the game area, and the start in the process of flowing down the game area By winning the winning device, a predetermined number of prize balls are paid out, and various game effects such as a reach effect accompanying the symbol change effect on the symbol display device are made, and the symbol display device has a predetermined set of symbols. By stopping at the same time, a so-called jackpot is generated, and the special prize-winning device is opened to obtain a large number of prize balls.

  Here, in the pachinko game hall, the pachinko ball that flows down the game area by bringing the magnet close to the glass surface of the pachinko machine is directly guided to the winning opening of the start winning device, or collected at a predetermined place. There is a case where a fraudulent act called “goto act” is performed.

  For example, in the pachinko machine disclosed in Patent Document 1, a magnetic sensor is arranged on the back side of the game board or the back side of the collective bowl attached to the back side of the game board, and the glass surface is intended for fraud. When the magnet is brought close to the magnet, the magnetism of the magnet is detected by a magnetic sensor, and the anti-tampering measures such as stopping the ball hitting device are taken.
