Mahjong machine was first invented and produced in Japan. At first, it was originally imported from Japan to China. Because of the huge market in China, the Japanese opened a factory in China in the early 1990s to mass-produce automatic mahjong machine, thus bringing mahjong machine to China. Since then, it has entered a period of rapid development and formed a huge industrial chain. At present, there are more than 500 domestic manufacturers with Queyou as the leader (1994 mahjong machine culture was introduced to China), with He Ming, Fuji Guangyi, Aolong and Queyuan as the main representatives, mainly concentrated in the Yangtze River Delta region, with Hangzhou Xiaoshan as the distribution center in mahjong machine, radiating the whole country; A number of industry media represented by Guofeng Business Daily, mahjong machine Business Information and Youcai Business Daily.

[Edit this paragraph] Working principle

The surface of the back of the mahjong tile contains magnets and other things that can be attracted by magnetic force, but not on the front. (The magnetic force is like this. You can stick a suction ring on the back of the mahjong card, but the front of the mahjong card has a certain thickness, which is not enough to attract mahjong. ) Tiles rotate with the disk on an inclined disk. When the card rises to a higher position, the card with the back facing upwards is attracted by the magnetic ring on the shuffling barrel, and rotates with the magnetic ring and is sent to the conveying slot. There is a small spring on the disc to turn over the cards, so that the cards on the front are turned down, and the cards on the back are attracted by the magnetic ring 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 lifting button on the operation panel, and the tray under the cards will send the cards folded on all sides out of the table. There is a motor in the mahjong table to drive the turntable and the chain (the chain has a push rod) to rotate, which is automatically controlled by the electronic chip. When the origin of mahjong was still inconclusive, Ningbo school adopted the method of secretly crossing Chen Cang. Ningbo people, who have always been good at business, believe in getting there first. While others are still arguing, the clever Ningbo people have quietly built a mahjong museum next to Tianyi Pavilion, saying that Ningbo is the real origin of mahjong.
