Problems solved by technology

But so far, the accuracy of this kind of identification is still not up to the requirements, so that the non-magnetic mahjong machine products are still not widely launched in domestic and foreign markets.

Embodiment 1

[0039] Please refer to figure 1 , The mahjong tiles are connected by two materials with different densities. among them figure 1 a and 1d are the side lying state of the card, figure 1 b and figure 1 c are figure 1 The left and right views of the mahjong card shown in a respectively show the front Z and the back F of the card. The length of the card is L, the width is S, and the thickness is B. The above two materials with different densities can be made of plastic materials with a lower density and plastic materials with a higher density (or a higher density material added to the plastic material). One side of the same is the same as the front or back of the card but the thickness is the same. Different rectangular block 1a and rectangular block 1b, the thickness of the rectangular blocks 1a and 1b are B1 and B2 respectively, and the sum of the two is exactly the thickness B of the mahjong tile. The card forms a side lying surface with its length L and thickness B lying on the...

Embodiment 2

[0042] See figure 2 , The mahjong tiles are also made of two different density materials. Made of a relatively low-density material, such as ordinary plastic, a rectangular cavity shaped like a card. The rectangular cavity is composed of a box 1.1b containing the front face Z of the card and a box cover 1.1a containing the back face F of the card. Materials such as high-density stone or iron are made of rectangular block 1.2. The rectangular block 1.2 fits into the cavity and is placed in the cavity corresponding to the front Z end of the card box body, connected to the inner bottom surface of the bottom end, close to One end of the Z on the front of the card. The box cover 1.1a is sealed on the opening end of the box body 1.1b by molding or other general technical means to form a mahjong tile 1. The card's center of gravity is biased to the front Z and to the side of the card's geometric center C. According to the above embodiment 1, the card also has a center of gravity th...

Embodiment 3

[0045] See image 3 , The mahjong tiles are made of one material. A cavity is provided on the inner side along the thickness direction of the card, for example, a cavity is provided on the inner side near the end of the reverse side F of the card, so that the density of the end near the reverse side of the card is less than the density of the end near the front side of the card. Make the density distribution of the cards different in the thickness direction. The specific structure can also be made into the structure of the box body 1.1b and the box cover 1.1a mentioned above, but the thickness H1 of the bottom end of the box body near the front end of the card is much larger than the thickness H2 of the bottom end of the box near the back end of the card, so that The center of gravity G is on the front side of the card. Of course, you can also shift the center of gravity to the back end of the card as needed, which is easy for those skilled in the art. Also according to the a...

Abstract

The invention relates to mahjong tiles. The tiles are different in density distribution in the thickness direction of the tiles, and the gravity center of the tiles inclines to the front side or the reverse side of the tiles. The mahjong tiles have the advantages that magnetic materials and corresponding photoelectric devices are not needed during mahjong tile surface recognition, and therefore cost can be greatly saved, consumption of rare earth materials is reduced, possibility of cheating on the tiles is reduced, simultaneously tile surface recognition by aid of gravity center of the tiles is very accurate, tile turnover operation is reliable, and a corresponding tile turnover mechanism is simple in structure and low in cost.

Description

[0001] technical field [0002] The invention relates to a mahjong tile in a mahjong machine. Background technique [0003] The mahjong tiles used in the existing mahjong machines are all magnetic, and the front side (character or white side) and the reverse side of the mahjong tiles have different magnetic properties. When the mahjong machine is working, these magnetic mahjong tiles are driven by the big turntable at the bottom of the shuffling barrel to rotate in the shuffling barrel, and the mahjong tiles move to the edge of the big turntable under the action of centrifugal force. A number of permanent magnet blocks are set under the big turntable, and the mahjong tiles may flip due to the magnetic force of the permanent magnet blocks when moving to the edge. Finally, flip the card with the same face, that is, the face of the down card is different from the corresponding magnetic pole of the permanent magnet block on the big turntable. These cards with the same face are...
