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

[0036] Please refer to figure 1 , the mahjong tile is formed by connecting two materials with different densities. in 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 tile shown in a show the front Z and the back F of the tile respectively. The length of the tile is L, the width is S, and the thickness is B. The above-mentioned two kinds of materials with different densities, for example, can be made of a plastic material with a lower density or a plastic material with a higher density (or a material with a higher density added to the plastic material) to make one side the same as the front or back of the card but have the same thickness. For the different rectangular blocks 1a and 1b, the thicknesses of the rectangular blocks 1a and 1b are B1 and B2 respectively, and the sum of the two is just the thickness B of the mahjong tiles. The board forms a side lying surface with its length L and...

Embodiment 2

[0038] See figure 2 , the mahjong tiles are also made of two materials of different densities. The material such as ordinary plastics with relatively small density is made as card-shaped cavity rectangular body, and this cavity rectangular body is made up of the box body 1.1b that comprises card face Z and the box cover 1.1a that comprises card backside F, uses density relatively big Materials such as high-density stone or iron are made with a rectangular block 1.2, which is adapted to the cavity and 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 The end of the Z on the face of the card. The box cover 1.1a is sealed to the opening end of the box body 1.1b by molding or other common technical means to form a mahjong tile 1 . The center of gravity of the card is offset from the face Z and to the side of the geometric center C of the card. According to the above-mentioned embodiment...

Embodiment 3

[0040] See image 3 , the mahjong tile is made of one material. A cavity is arranged on the inside along the thickness direction of the card, for example, a cavity is arranged on the inside near the end of the reverse side F of the card, so that the density near the reverse side of the card is smaller than that of the card near the front side of the card. The density distribution of the cards is made different in the thickness direction. Its specific structure can also be made into the structure of the above-mentioned box body 1.1b and box cover 1.1a, 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 box bottom end near the end of the back side of the card, so that The center of gravity G is biased towards the front end of the card. Of course, the center of gravity can also be shifted to the reverse side of the card as required, 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

technical field [0001] The invention relates to a mahjong tile in a mahjong machine. Background technique [0002] 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 magnetic...
