PROBLEM TO BE SOLVED: To provide an inversion device which enables the quick and exact inversion of the desired tile on a row of the wall tiles on the upper stage side to make a Dora designating tile when the tiles are stacked in two stages on the wall tile array stand in an automatic mahjong table. SOLUTION: In the automatic mahjong table, a wall tile array stand is located in the center thereof and a wall tile lifter and a skidding member which skids a row of the wall tiles stacked in two stages on the wall tile array stand to the wall tile lifter are arranged thereon. A tile sticking piece composed of a magnet is so arranged as to be driven forward into or backward from one end part of the wall tile lifter in the direction of crossing the wall tile array stand through an inlet/outlet provided in a vertical wall surface part of the wall tile lifter and is reciprocated freely, so that the upper end part of one side end of the tile to be turned into the Dora display tile is stuck upward with the reciprocation of the tile sticking piece. The display surface of the tile is magnetically attracted onto the underside of the tile sticking piece to get the tile inverted while the other end side thereof is stopped with the skidding member.
