As described above, according to the automatic mahjong table of the present invention, each of the tile supply ports provided on four sides of the top plate is closed by a pair of tile placement tables which open and close in a double-opening manner. A lifting plate is provided directly below the opening of the tiles for loading the tiles stacked in two stages, and each lifting plate is sequentially lowered to a height of one and two stages to supply the tiles on the turntable with supply means. Since the tiles conveyed from the turntable side via the conveying means are configured to be loaded on each elevating base plate from one end side of each elevating base plate by the feeding means, it is similar to a conventional automatic mahjong table. In contrast to the mechanism in which tiles are sequentially stacked in two layers on tiles on four sides, tiles can be loaded on all four sides of the elevating platform at the same time. It can speed up.

Further, a bi-folding tile mounting table and a lifting platform are provided so as to be able to move up and down directly below each tile supply port provided on each side of the top plate, and the tile mounting table is moved upward on the lifting platform. Is opened so that the tiles stacked in two stages on the elevating base plate are transferred to the tile placing table. The space inside the console body can be designed to be as small as possible without the need for a large space such as a device for horizontally feeding tiles stacked on a pallet, and the mechanism of the entire device is simplified, making maintenance and inspection easier. Therefore, even if the tile is a large tile such as a Hong Kong size tile, the mechanism is simple and the internal space in the desk can be widened as described above.

In addition, the two-stage stacked elevating base plates are raised toward the tile supply port immediately above, and a pair of tile placement tables whose tile supply ports are closed are opened in a double-opened state to place these tiles. After protruding the two-tiered tiles on the elevating platform upward from between the pair of tile platforms through the space between the platforms, the pair of tiles are moved in the closing direction, while the elevating platform is lowered. Due to the configuration, by moving the pair of tile mounting tables in the closing direction, the lower surfaces of the two side stacked tiles projecting outward from both sides of the lifting platform on the opposite ends of these tile mounting tables are received. The tiles are stopped and the two-tiered tiles are smoothly transferred from the elevating base plate to the tile mounting base. The tile supply port is closed by each tile mounting base, and at the same time, a two-tiered castle wall is stacked on each tile mounting base. A tile can be formed.

According to the fifth aspect of the present invention, a sensor for detecting the number of tiles sent from the tile supply means to the tile transport means side is provided in close proximity to the tile supply means comprising a rotating disk or a traveling chain. After the predetermined number of tiles have been sent to the transport means side, a stopper means comprising a solenoid for preventing the tiles from being sent from the tile supply means to the tile transport means side is provided. Can be reliably supplied to a predetermined number on the four lifting base plates.

Further, as described in claim 6, a belt conveyor is employed as means for transporting tiles from the turntable to the four sides of the lifting platform, and a tile guide fixed at a constant height along the belt conveyor. A belt conveyor is provided by disposing detachable tile cleaning tools having a cross-sectional gate shape provided with brushes that slide on the inner surfaces from the upper surface of the tiles to both side surfaces. The surface of the tile conveyed by the tile can be cleaned cleanly by the tile cleaning tool, so that the tile can always be a clean tile and the game can be played, and the tile cleaning tool can be replaced with a cassette type. Therefore, the handleability is simple, and when it becomes dirty, it can be easily replaced.

According to the seventh aspect of the present invention, a tile extruding piece is provided at the tip of an arm member which reciprocates and rotates in synchronism with the transport speed of a tile transporting means comprising a belt conveyor as the feeding means. The pieces are moved toward and away from one end of the elevating base plate on the tile receiving frame provided at the transport end of the tile transporting means, so that the tiles sent by the transporting means are sequentially and surely placed. And a predetermined number of them can be supplied on the lift base plate. In addition, since the tile cleaning tool having a cross-sectional gate shape is detachably mounted on the tile receiving frame portion while the tiles are being fed, the front and rear end faces of the tiles that are not cleaned by the tile cleaning tool provided on the belt conveyor side are removed. It can be cleaned smoothly with a tile cleaning tool.
