[Effects of the Invention] As is apparent from the above description, the enclosed gaming machine according to the present invention is between the recovery path for collecting all the balls fired and the supply path for supplying the hitting balls to the firing position. Since it is polished by the ball polishing device interposed in the machine, the polished balls can be used repeatedly, so that the surface of the game board of the enclosed game machine is not polluted for a long time, and the length of the enclosed ball is long. It is possible to maintain a good flowing state over a period of time. In particular, a sprocket that engages one ball flowing down from the recovery path and conveys it to the supply path, a drive source that rotationally drives the sprocket, and a friction plate that contacts the conveyed ball located on one side of the sprocket. And a polishing member which is located on the other side surface of the sprocket and is pressed by the biasing force of the spring so as to press the conveyed balls, and the balls to be conveyed are friction members. Since it is carried while being sandwiched by the friction plate and constantly rotated by the friction plate, the dirt on the surface of the ball can be wiped cleanly over the whole even during a very short conveyance distance on the back surface of the enclosed game machine. Further, since the ball polishing device is built-in, a complicated mechanism for replacing the enclosed ball is not required and the polishing member can be replaced very easily.
