A: Ask F6; y-l0Q？ The decorative layer on the back of mahjong tiles is magnetic, but not on the front. Tiles rotate with the disk on an inclined disk. When the tile rises to a high place, the tile on the magnetic side is attracted by the iron ring plate above the disc, and is sent into a groove along with the rotation of the ring plate, and pushed away by the shifting rod. The tiles without magnetism on the front continue to rotate on the disk surface, and the tiles on the groove are folded in pairs and distributed to all sides by the push rod. There is a small spring on the disc to turn over the cards, so that the cards on the front side can be turned down and attracted by the iron ring with the magnetic face up, until all the cards are finally sent to the slot to be taken away. When there are enough cards on all sides, people will control the button and the tray under the cards will send the cards folded on all sides out of the table. $ j @ { Y； uuTd

There are five motors in the mahjong table to drive the turntable and chain (with push rods on the chain) to rotate, which are automatically controlled by electronic chips. l%L-I{Li/a8T

In addition, there are control circuits such as "color" and transmission positioning, which are controlled by special chips. There are slight differences between different circuits of manufacturer brands.
