When the mahjong machine receives a mahjong-playing signal, the lifting support plates in the four groups of mahjong-picking and carrying systems all descend, the mahjong tiles in the tile storage grooves are pushed onto the table surface of the mahjong machine by the upper mahjong pushing heads, wherein the horizontally moving upper mahjong pushing heads are provided with a plurality of mahjong-pushing parts, the mahjong-pushing parts respectively contact two mahjong tiles stacked up and down in the last pier, the mahjong-pushing part in contact with the lower mahjong tile protrudes out of the mahjong-pushing part in contact with the upper mahjong tile, when the upper mahjong pushing heads push the plurality of mahjong tiles to horizontally move, the upper mahjong tile lags behind the lower mahjong tile, and when the upper mahjong pushing heads push the last mahjong tile up to the inclined lifting support plates, the upper mahjong tile is level with the lower mahjong tile; when the sensor B outside the card outlet of the card storage groove detects the signal that the card pushing head is in place, the card lifting supporting plate rises upwards to be flush with the desktop of the mahjong machine, and the card pushing head is reset.

If the card feeding motor in the card feeding device is saved, the conveying belt in the square card feeding device can be in transmission connection with the shuffling motor of the large shuffling tray, so that an electronic control counting gate or a card feeding detection device is required to be arranged at a card feeding port of the card feeding channel, the electronic control counting gate is easy to damage and has a short service life, the card feeding detection device is preferably selected, and the number of cards fed into each group of card picking and conveying systems is controlled by stopping the operation of the card pushing device in the midway. Therefore, another mahjong machine control method is as follows:
