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

[0038] Please refer to figure 1 , the mahjong tile is formed by connecting two materials with different densities. in figure 1 a is 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. Above-mentioned two kinds of materials of different densities, for example, can adopt the less common plastic material of density and make the rectangular block 1a and the rectangular block 1b that its one side is equal to the card front or reverse side but different in thickness respectively with the higher plastic material of density, rectangular The thicknesses of 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 thickness B and lies on the support surface, such as ly...

Embodiment 2

[0040] 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

[0042] 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 a mahjong tile surface identification method. Tiles lie on a tile conveying groove and run in the tile conveying groove. The mahjong tile surface identification method is characterized in that the center of gravity of each of the tiles slants to one side of the front surface or the back surface of each of the tiles; when the tiles run to an output of the tile conveying groove, the center of gravity of each of the tiles is outside a supporting surface on which the tiles lie, and the tiles are turned on one side in a direction under the action of gravity to fall into an identification groove; and the tiles in the identification groove lie in the identification groove in a mode that the front surfaces or back surfaces of the tiles are consistent. The mahjong tile surface identification method has the advantages that magnetic materials and corresponding photoelectric identification elements and circuits are not required, accordingly on one hand, the cost is greatly saved and consumption of rare earth materials is reduced, one the other hand, the possibility of cheating on tiles is decreased. Besides, identifying tiles surfaces according to the center of gravity of the tiles is accurate, the reliability of flipping action is improved, and corresponding tile flipping mechanisms are simple in structure and low in cost.

Description

Technical field [0001] The invention involves mahjong machines, especially a method of identifying mahjong cards. Background technique [0002] The mahjong cards used by the existing mahjong machine are magnetic, and the front of the Mahjong card (character or white surface) and the negative are different.When working at the mahjong machine, these magnetic mahjong cards are driven by the large turntable at the bottom of the shuffle barrel in the shuffle barrel, and the Mahjong card is moved to the edge of the large turntable under the action of centrifugal force.There are several permanent magnet blocks under the large turntable. During the process of moving to the edge, Mahjong may flip due to the magnetic force of the permanent magnet block.The brand with the same face of the card is the same, that is, the downward card is the same as the magnetic pole corresponding to the permanent magnetic block on the large turntable.These cards are consistent with the cards that are sucked ...
