Description

[Detailed explanation of the idea] [Industrial application field]

In this invention, an automatic tile alignment device is housed inside a machine frame formed in a flat box shape, and a lifting platform is installed that can be raised and lowered to lift up mahjong tiles that have been arranged in a stacked state by the automatic tile alignment device. A mahjong table is provided in the shape of a top plate that can be opened and closed at the top of the machine frame, and the mahjong table is provided with a droplet that can be opened and closed for dropping mahjong tiles after finishing the game into the machine frame. ,and,
The present invention relates to an improvement in an automatic mahjong table configured with a window hole through which the elevating platform appears and disappears.

[Conventional technology]

In the conventional automatic mahjong table having the above-mentioned configuration, the machine frame is formed into a flat box shape that is basically square when viewed from above, and the open opening on the top side of the machine frame is formed into a flat box that is approximately square when viewed from above. A four-person mahjong game in which the formed mahjong table is mounted, a tile droplet is provided in the center part of the table so that it can be opened and closed, and window holes are provided in the parts corresponding to each edge of the periphery to make the elevating platform appear and disappear. There is no automatic mahjong table for three-person mahjong.

[Problem that the idea aims to solve]

For this reason, due to the fact that the four members are not available,
When playing three-person mahjong, one edge of the four edges of the machine frame, which is approximately square in plan view, is left open, and the three-person mahjong is placed at a position corresponding to the three edges. There is a problem in that the players have to play the game one by one, which creates a sense of discomfort in the progress of the game. The present invention was made to solve this problem that occurs with conventional methods, and when three people play a game of mahjong using an automatic mahjong table, it creates wasted space in the room. To provide an automatic mahjong table for three-person mahjong with which the game can be enjoyed without straining, without feeling strange, and without mistakes or misunderstandings.

[Means to solve the problem]

In the present invention, as a means to achieve the above-mentioned object, an automatic tile alignment device is housed inside a machine frame formed in a flat box shape, and the mahjong tiles are arranged in a laid-up state by the automatic tile alignment device. A lifting platform is installed that can be raised and lowered, and a mahjong table is mounted on the open opening on the top side of the machine frame in the form of a top plate that can be opened and closed. In an automatic mahjong table provided with a window hole through which an elevating table appears and retracts, the flat box-shaped machine frame is formed so as to have a shape based on a substantially equilateral triangle having three long edges when viewed from above. A mahjong table formed in a shape similar to the machine frame in plan view is mounted on the top side of the machine frame so as to be openable and closable, and a mahjong table is mounted at three locations on the inside of each of the three long edges of the mahjong table. , a window hole through which the lifting platform appears and disappears is arranged parallel to each edge thereof, and the lifting platform is arranged at a position corresponding to the window hole and is installed in the machine frame so as to be able to rise and fall freely. This paper proposes an automatic mahjong table for three-person mahjong.
