The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle with the bottom edge of the table, namely the windmill shape is inclined, so that the table top can be made smaller, and the inclination of the card strips also accords with the habit of a player; secondly, when the card is played, the whole card pier is not built and then lifted up to the tabletop, but pushed up to the tabletop along the slope, so that the space inside the machine can be reduced, and the size of the whole machine can be reduced. However, in the card discharging device, the whole card storage groove is arranged in a slope shape, the resistance of the card feeding process is large, the load of a steel wire rope motor is large, steel wires are easy to shake and break, the card feeding process is not stable enough, the service life of the steel wire rope is low, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong cards from a large tray and conveying the mahjong cards to the stacking and pushing machine head) is unreasonable, the conventional square independent stacking and pushing machine head is difficult to push mahjong cards to a card inlet of a card storage groove track, and the height of a host machine is high.

The height of the tile feeding system is basically level with that of the tile lifting system, so that although the height of the host is reduced, the arrangement position of the tile lifting system can cause interference to the shuffling of a large tray and the suction of the mahjong tiles by the tile feeding system, and the tile lifting system is only suitable for small mahjong tiles. In addition, the arrangement of the tile outlet of the tile feeding system and the tile inlet of the tile feeding track is unreasonable, the tile pushing device does not have the tile stacking function, and the mahjong tiles are automatically stacked on the tile bearing table board, so that the mahjong tiles are not stacked neatly and are easy to move and misplaced, and the mahjong tiles cannot enter the tile feeding track, and generate faults such as confusion in the tile feeding track. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the adoption of the chain and the flag wheel structure has high noise.
