The present invention relates to a game ball delivery device capable of delivering a specified number of pachinko balls as the game medium in a game machine.

[Technical background]

As one of the representative examples of this type of symbol type gaming machine, in the gaming machine which is conventionally generally called "slot machine",
As is well known, medals or coins are used as the medium required for each symbol combination game, and these medals are inserted in units of one in accordance with the game conditions (up to three for up to three games) to start the game operation. By doing so, the symbol display device (usually the rotating drum) is variably operated and the game can be played. Then, in the determination result of the symbol combination fixedly displayed on the same device, when it matches with the preset “combination of symbols”, it is determined that the winning is achieved, and a predetermined reward, that is, a set number of the above medals or the like can be obtained. .

Such a gaming machine, when compared with a general pachinko machine, leads to various aspects such as game methods and contents of both sides, and form and configuration in relation to differences in game media (medal etc. and pachinko ball) used mutually. Although there is a big difference, they have the same outer size (width and height), and they are interchangeably installed in a pachinko machine in a game store. For that reason, as one of the new types of this type of gaming machine, a model capable of playing a symbol combination game unique to the gaming machine by using a pachinko ball as a game medium is being sought after.
