  The present invention relates to a pachinko gaming machine, and more particularly to a pachinko gaming machine provided with a symbol display device for displaying a specific symbol.

Conventionally, as a kind of gaming machine, a pachinko gaming machine having a symbol display device (variable display device) for variably displaying a plurality of types of symbols in a predetermined arrangement is known.
In this type of pachinko gaming machine, when a game ball launched into the game area formed on the game board wins a start opening, the identification information such as various symbols is scrolled on a variable display device including a liquid crystal display screen. A variable display game is executed in which variable display is performed and the variable display is stopped after a predetermined time has elapsed.
The display result when the variable display in the variable display game is confirmed to be stopped is confirmed as a special display mode that is a combination of predetermined identification information, for example, all the same identification information is aligned on the same position line (for example, “333”). Then, a special gaming state (a big hit state) occurs. In other words, a state in which a game value can be given to the player is formed by repeatedly opening and closing the grand prize opening a predetermined number of times.

For example, a liquid crystal display device is widely used as the symbol display device as described above.

In a center accessory device that is internally provided with a symbol display device constituted by a liquid crystal display device or the like, if the game ball frequently collides with the liquid crystal display screen, the liquid crystal screen may be damaged, and thus it cannot be used for a long time. For this reason, in order to protect the symbol display device, a center frame member is usually attached around the symbol display device.

By the way, in the pachinko gaming machine as described above, if the falling speed of the game ball is too high, it becomes difficult to guide the game ball to the start port and the winning port, and a decoration member provided on the game board, etc. There was a risk of damage. Also. When the falling speed of the game ball is high, it is difficult for the player to visually recognize the game ball, and there is a possibility that the game performance is impaired.
For this reason, in the pachinko gaming machine, a guide passage for guiding a game ball called a celestial portion to both sides of the center accessory device is formed above the center frame member of the center accessory device to form the center accessory device. By guiding the game balls to the left and right, the falling speed of the game balls was suppressed. Note that there are Patent Documents 1 to 4 as prior documents.
