１外に排出されるようになる。 After a game on the top surface of the top plate 2 that forms the mahjong table is completed, the mahjong tiles are placed in the slot 20 of the top plate 2.
The tile is dropped into the machine frame 1, and then the motor M is driven by a switch operation to cause the lifting platform 3 to lower and ascend. When performing an operation to transfer the mahjong tiles that are arranged in a stacked state on the top surface, a foreign object such as a dot stick B or a match stick accidentally falls into the hoistway w of the hoisting platform 3. In this case, the foreign object such as the fallen point stick B or the matuchi shaft is removed from the platform 3 by the aligned mahjong tiles pushed out by the tile extrusion device 7 when the platform 3 descends to the lower limit. It is carried to the guide member 8 side so as to be swept out on the table surface 3a,
The foreign matter is pushed out into the space formed by the notch 8a provided at the lower part of the guide member 8, falls downward from the notch 8a, and is passed through the removal port 14 provided in the base plate 10 of the machine frame 1 by the foreign material ejection chute 9. It will now be ejected outside frame 1.

る。 As explained above, the foreign matter ejecting device for the automatic mahjong table according to the present invention raises and lowers the lifting platform,
When the mahjong tiles that are waiting in the machine frame are being lifted up to the top surface of the top board, foreign objects such as dots that fell into the hoistway of the hoisting platform may fall onto the surface of the hoisting platform that has descended. The mahjong tiles in the tiled state that are pushed out are swept out of the hoistway and are ejected out of the machine frame via the foreign matter ejection chute, causing them to fall into the hoistway. Foreign objects may be located at the bottom of the hoistway and obstruct the movement of the mahjong tiles that are pushed out there, or they may be lifted up together with the pushed out mahjong tiles as the hoistway rises, and the top board may be damaged. It is possible to effectively eliminate the problem of getting stuck on the edge of the window hole and obstructing the lifting of the platform.
