Description

Technical Field

[0001] This invention belongs to the technical field of entertainment equipment, card-arranging machines, mahjong machines, and mahjong tiles. Specifically, it relates to a square entertainment card and a card-arranging machine. Background Technology

[0002] Currently, existing tile sorting machines require arranging block-shaped game tiles into stacks and then pushing them in front of the players. For example, taking a mahjong machine as an example, a fully automatic mahjong machine works by stacking the tiles and then using a tile-lifting mechanism inside the machine to lift them onto the table for easy access. However, existing mahjong tiles have overly smooth surfaces, making them prone to slipping and falling during gameplay. These tiles are easily damaged when dropped on the ground, and they also affect the user's grip.

[0003] Therefore, it is necessary to make changes. Summary of the Invention

[0004] The purpose of this invention is to provide a block entertainment card and a card sorting machine to solve the problem of block entertainment cards easily slipping off in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a square entertainment card, wherein a recessed portion is provided on the surface of the square entertainment card body, and a rough surface is provided on the recessed portion. The rough surface improves the user's feel during entertainment and also prevents slippage.

[0006] Preferably, the character surface of the square entertainment card has a recessed portion, while the other surfaces do not have recessed portions, and the recessed portion has a rough surface. This makes the graphics on the surface of each square entertainment card neat and beautiful, or keeps the original square entertainment card unchanged. Some users habitually touch the character surface, and the rough surface on the character surface improves the user's feel, while the other surfaces remain smooth.

[0007] Preferably, the character surface of the square entertainment card has a recessed portion and the back surface opposite to the character surface are provided, and the recessed portion has a rough surface. This makes the graphics on the surface of each square entertainment card neat and beautiful, or keeps the original square entertainment card unchanged. Some users habitually touch the character surface and the back surface corresponding to the character surface. The rough surface improves the user's feel, while the other surfaces remain smooth.

[0008] Preferably, the six sides of the square entertainment card have recessed portions, and the recessed portions have roughened surfaces. This makes the graphics on the surface of each square entertainment card neat and aesthetically pleasing. Since some users habitually touch the square entertainment cards, the roughened surfaces improve the user's feel and reduce the number of times they slip.

[0009] Preferably, the thickness of the roughened surface is 0.1-0.3mm, more preferably 0.2mm. This avoids excessively high protrusions between the roughened surfaces, which would affect the user's feel and hinder the shuffling of the cards by the card sorting machine. Since the thickness of a fingerprint on the surface of a finger is approximately 0.3mm, the depth of the roughened surface on the surface of the square entertainment card is designed to be 0.5mm, which improves the user's feel while preventing slippage.

[0010] Preferably, the raised portions of the square entertainment card characters are not designed with a rough surface. This design caters to user needs; some users habitually use their fingers to touch the raised portions of the characters for identification. A rough surface increases friction between the finger and the character, improving the user's feel. This design satisfies the needs of some users.

[0011] Preferably, the raised portion of the square entertainment card character has a rough surface. Designed according to user needs, some users habitually use their fingers to touch the raised portion of the character for identification; the rough surface increases friction between the finger and the character, improving the user's feel. This design meets the needs of some users.

[0012] Preferably, the distance between the upper part of the outer edge of the recessed portion and the edge of the square entertainment card is 1-5mm, and the distance between the upper part of the outer edge of the recessed portion and the edge of the square entertainment card is 2mm. To avoid damage to the rough surface during the grinding process of the square entertainment card, the rough surface is recessed by 0.2mm. This reduces wear on the rough surface during grinding, specifically ensuring that the grinding process reaches the position where the upper part of the outer edge of the recessed portion is 2mm from the edge of the square entertainment card, thus minimizing wear. This leaves a 2mm smooth surface between the edge of the square entertainment card and the recessed portion, which is beneficial for the card shuffling machine.

[0013] Preferably, the rough surface includes multiple grooves spaced apart. The groove array is arranged on the recessed portion, which makes the graphics on the surface of each square entertainment card neat and aesthetically pleasing, and the protrusions between adjacent grooves help improve the user's feel and prevent slippage.

[0014] Preferably, the grooves include rectangular grooves. After the rectangular grooves are arranged in an array on the surface of the square entertainment card body, the protrusions between adjacent rectangular grooves have a grid-like design. The grid-like protrusions between adjacent grooves improve the user's tactile experience.

[0015] Preferably, the groove includes a linear groove, the protrusion between adjacent linear grooves is a strip design, the protrusion between adjacent linear grooves is a spiral design, the protrusion between adjacent linear grooves is a circular design, and the protrusion between adjacent linear grooves is a straight line or a curve design. The linear groove design is used to decorate the fingerprint of the finger on the surface of the square entertainment card body, increasing the friction between the finger and the card during the entertainment process to prevent it from slipping off.

[0016] Preferably, the depth of the groove is 0.1~3mm, and more preferably 0.5mm, to avoid excessively high protrusions between adjacent grooves, which would affect the user's feel and also hinder the shuffling of the cards by the card sorting machine. Since the thickness of fingerprints on the surface of a finger is about 0.5mm, the groove depth on the surface of the square entertainment card is designed to be 0.5mm to prevent slippage.

[0017] Preferably, the width of the protrusion between the spaced grooves is 0.1~3mm. Preferably, it is 0.5mm to avoid excessively wide protrusions between adjacent grooves, which would affect the user's feel. Since the thickness and width of fingerprints on the surface of a finger are both approximately 0.5mm, a width of 0.5mm between adjacent grooves on the surface of the square entertainment card prevents slippage.

[0018] Preferably, the depth of the recessed portion is 0.1-3mm, more preferably 0.5mm. This avoids the recessed portion being too deep, which would affect the user's feel and the shuffling of the card sorting machine. Maintaining a depth of 0.5mm between the edge of the diamond game cards and the recessed portion facilitates the shuffling of the card sorting machine and also allows them to be neatly arranged on the table.

[0019] Preferably, there is a gap between the edges of the characters on the square entertainment card and the recessed portion. This design facilitates user touch; that is, the outer edges of the characters are raised to facilitate touch recognition and improve the user's tactile feel. Existing technology uses a parallel design.

[0020] Preferably, the distance between the edge of the character on the square entertainment card and the recessed portion is 0.1-1mm, preferably 0.2mm. Maintaining the distance within 0.2mm facilitates touch recognition and avoids excessively wide distances that affect the user's feel, i.e., affect finger touch. This design facilitates user touch by adding a raised portion to the outer edge of the character, which facilitates touch recognition and improves the user's feel. Existing technology uses a parallel design.

[0021] Preferably, there is a gap between the edges of the characters on the square entertainment card and the rough surface. The characters and the recessed part are recessed at the same time, and the gap between the outer edge of the character and the rough surface makes it easier for the user to identify the square entertainment card when touching it with their finger. That is, the outer edge of the character is partially smooth, which helps to improve the user's feel, facilitates the shuffling of the card by the card sorting machine, and also allows the cards to be neatly placed on the table.

[0022] Preferably, the distance between the edge of the character on the square entertainment card and the rough surface is 0.1-1mm, preferably 0.2mm. Maintaining the distance within 0.2mm facilitates touch recognition and avoids excessively wide distances that would affect the user's feel, i.e., affect finger touch. This design facilitates user touch, i.e., the outer edge of the character maintains a certain smooth distance from the rough surface, which facilitates user touch recognition and improves the user's feel. Existing technology uses a smooth design.

[0023] Preferably, the square entertainment tiles are mahjong tiles. Square entertainment tiles include various square-shaped entertainment tiles; in this embodiment, mahjong tiles are used. Square entertainment tiles are manufactured according to user needs, such as dominoes or other square-shaped linear tiles.

[0024] The present invention provides a card sorting machine, wherein the card sorting machine is provided with the square entertainment cards described in the present invention.

[0025] Preferably, the card sorting machine is a mahjong machine or a dominoes machine.

[0026] Preferably, the square entertainment tiles are mahjong tiles, and the mahjong tiles are placed inside the mahjong machine.

[0027] Preferably, the square entertainment cards are Pai Gow, and the Pai Gow are placed inside the card machine.

[0028] Compared with the prior art, the present invention has the following advantages: This invention improves the user's feel and reduces the frequency of slippage by creating a recessed portion on the main body of the square entertainment card and providing a rough surface on the recessed portion, with the rough surface maintained at a depth of 0.3mm. Since the thickness of a fingerprint on the surface of a finger is about 0.3mm, and the depth of the rough surface on the surface of the square entertainment card is 0.3mm, this design improves the user's feel and also prevents slippage.

[0029] This invention improves user feel and reduces slippage by creating a recessed portion on the character surface of the square entertainment card body and providing a rough surface on the recessed portion, with the roughness maintained between 0.3mm. Since the thickness of a fingerprint on the surface of a finger is approximately 0.3mm, and the depth of the rough surface on the square entertainment card surface is 0.3mm, this design improves user feel and also prevents slippage.

[0030] This invention features recessed portions on the character surface and the corresponding back surface of the square entertainment card body. A rough surface is provided on the recessed portion, with the roughness maintained between 0.3mm, improving user feel and reducing the frequency of slippage. Since the thickness of a fingerprint on the surface of a finger is approximately 0.3mm, and the rough surface depth on the square entertainment card surface is 0.3mm, this design improves user feel and prevents slippage.

[0031] This invention features recessed sections on all six sides of the square entertainment card body, with roughened surfaces on these recessed sections, maintaining a roughness level of 0.3mm. This improves the user's tactile experience and reduces the frequency of slippage. Since the thickness of a fingerprint on a finger surface is approximately 0.3mm, and the roughened surface on the square entertainment card surface is 0.3mm deep, this design enhances the user's tactile experience and prevents slippage.

[0032] The rough surface array design of this invention features grooves and raised sections between adjacent grooves, improving the feel for diners, reducing slippage, and facilitating finger-based identification. Specifically, since some users habitually use multiple fingers for identification, grooves with a depth and width of 0.3mm are provided on the square game board or character surface to enhance the user's tactile experience.

[0033] The groove of the present invention includes rectangular grooves, which are arranged in an array on the touch component. The protrusions between adjacent rectangular grooves are designed in a grid pattern, or the recesses between adjacent rectangular grooves are designed in a grid pattern. The grid-shaped protrusions or recesses help to improve the user's tactile feel. At the same time, the user can identify the square entertainment card by touching the groove gaps or the groove protrusions.

[0034] The groove of this invention includes linear grooves, with the protrusions between adjacent linear grooves being strip-shaped, spiral-shaped, circular, or straight-line or curved. The linear grooves are designed to incorporate fingerprints on the character surface of the square entertainment card, increasing friction between the finger and the card during gameplay and preventing slippage.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] The square entertainment card uses mahjong tiles as an example for ease of understanding by those skilled in the art, and the inner card machine also uses mahjong tiles as an example for ease of understanding by those skilled in the art.

[0039] like Figure 1-9 As shown, a square entertainment card 1 has a recessed portion 3 on its surface, and a rough surface 2 on the recessed portion 3. The rough surface 2 improves the user's feel during gameplay, reduces the number of times the card slips, and avoids wear and tear on the card. The thickness of the rough surface 2 is preferably 0.3mm. Some users habitually identify the card by touching it with their ten fingers or thumb. During the touching process, the 0.3mm rough surface 2 improves the user's tactile feel and increases the friction between the card and the fingers, reducing the number of times the card slips. Because the surface of the existing square entertainment card 1 is too smooth, it is easy to slip during gameplay, which can easily cause the card to fall and be damaged.

[0040] like Figure 1-4 As shown, the character surface of the square entertainment card 1 has a recessed portion 3, while the other surfaces do not have recessed portions 3. The recessed portion 3 has a roughened surface 2. This ensures that the graphics on the surface of each square entertainment card 1 remain unchanged during gameplay. The roughened surface 2 on the character surface covers the table or the square entertainment card 1, without affecting the user's gameplay. Some users habitually touch the character surface with their fingers; the roughened surface 2 improves the user's tactile experience, while the character grooves on the character surface remain unchanged. This enhances the tactile experience and facilitates user identification. The other five surfaces of the square entertainment card 1 remain smooth.

[0041] like Figure 1 As shown, the character surface of the square entertainment card 1 is provided with a recessed part 3, while the other surfaces are not designed with recessed parts 3. The recessed part 3 is provided with a rough surface 2. The raised part of the character on the character surface is not designed with a rough surface 2. The user habitually touches the character surface with their finger. The rough surface 2 on the character surface improves the user's feel. The raised part of the character surface makes it easier for the user to identify. In this way, the feel is improved and the user can identify the character at the same time. The other five surfaces of the square entertainment card 1 remain smooth.

[0042] like Figure 2As shown, the character surface of the square entertainment card 1 has a recessed part 3, while the other surfaces do not have a recessed part 3. The recessed part 3 has a rough surface 2. The rough surface 2 is designed on the raised part of the character on the character surface. When users habitually touch the character surface with their fingers, the rough surface 2 on the raised part of the character on the character surface improves the user's feel and increases the friction between the user and the fingers. The raised part of the character on the character surface makes it easier for the user to identify. In this way, the feel is improved and the user can identify the character at the same time. The other five surfaces of the square entertainment card 1 remain smooth.

[0043] like Figure 7 As shown, the character face of the square entertainment card 1 and the opposite back face are provided with a recessed portion 3, and the recessed portion 3 is provided with a rough surface 2. Considering the needs of some users, namely, users habitually touch the character face and the corresponding back face with their fingers, the rough surface 2 is provided on the character face and the opposite back face of the square entertainment card 1, providing a better feel for the user. In this way, the graphics on the surface of each square entertainment card 1 are neat and beautiful, or the graphics on the character face and the corresponding back face of each square entertainment card 1 are aesthetically pleasing as a whole, while the other four faces remain smooth or unchanged. Since some users habitually touch the character face and the corresponding back face, the rough surface 2 increases the friction between the user and their fingers, improves the feel for the user, and reduces the number of times the card slips, thus reducing the damage to the square entertainment card 1 caused by falling.

[0044] like Figure 8-9 As shown, each of the six sides of the square entertainment card 1 has a recessed portion 3, and the recessed portion 3 has a rough surface 2. This makes the graphics on each square entertainment card 1 neat and aesthetically pleasing. Since some users habitually touch multiple sides of the square entertainment card 1, the rough surface 2 improves the user's feel during gameplay, increases the friction between the fingers and the square entertainment card 1, prevents slippage, reduces the number of times the square entertainment card 1 slips, and thus reduces the number of times the square entertainment card 1 is damaged.

[0045] like Figure 9 As shown, the character surface of the square entertainment card 1 has a recessed part 3, while the other surfaces do not have a recessed part 3. The recessed part 3 has a rough surface 2. The raised part of the character on the character surface does not have a rough surface 2. Users habitually touch the character surface with their fingers. The rough surface 2 increases the friction between the finger and the user, and improves the user's feel. The raised part of the character on the character surface makes it easier for the user to identify. In this way, the feel is improved and the user can identify the character at the same time. The other five surfaces of the square entertainment card 1 remain smooth.

[0046] like Figure 8As shown, the character surface of the square entertainment card 1 is provided with a recessed part 3, while the other surfaces are not designed with recessed parts 3. The recessed part 3 is provided with a rough surface 2. The rough surface 2 is designed on the raised part of the character on the character surface. When users habitually touch the character surface with their fingers, the rough surface 2 on the raised part of the character on the character surface improves the user's feel. The raised part of the character on the character surface makes it easier for the user to identify. In this way, the feel is improved and the user can identify the character at the same time. The other five surfaces of the square entertainment card 1 remain smooth.

[0047] like Figure 1-9 As shown, the thickness of the rough surface 2 is 0.1-0.3mm, preferably 0.2mm. This avoids excessively high protrusions between the rough surfaces 2, which would affect the user's feel and also hinder the shuffling of the cards by the card sorting machine. Since the thickness of fingerprints on the surface of a finger is approximately 0.3mm, the depth of the rough surface 2 on the surface of the square entertainment card 1 is designed to be 0.5mm, which improves the user's feel while also preventing slippage.

[0048] Continue as Figure 1-9 As shown, the square entertainment tile 1 is a mahjong tile. Most existing mahjong tiles are molded using a die-casting design. The die has uneven grooves with a height / width of 0.5mm. After the die is completed, the material for the square entertainment tile 1 (the mahjong tile) is filled into the die. After the die is processed into the square entertainment tile 1 (the mahjong tile), the rough surface 2 is formed on the square entertainment tile 1. Thus, the square entertainment tile 1 (the mahjong tile) and the rough surface 2 are integrally formed. This mahjong tile processing technology is existing technology. Refer to a mahjong tile manufacturing method, patent number CN200410006026.3, or refer to existing papers on mahjong tile processing.

[0049] like Figure 1-6 As shown, the surface of the square entertainment tile 1 has a rough surface 2 on the character surface, while the other five surfaces do not have a rough surface 2. The rough surface 2 is added to the character surface during the design process. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are set on the character surface within the mold. After completion, the material for the square entertainment tile 1, i.e., mahjong tile, is filled into the mold and processed into the square entertainment tile 1, i.e., mahjong tile. The rough surface 2 is then set on the square entertainment tile 1. In this way, the square entertainment tile 1, i.e., mahjong tile, and the rough surface 2 are integrally formed. Mahjong tile processing is existing technology. Referencing a mahjong tile manufacturing method, patent number CN200410006026.3.

[0050] like Figure 1 , 3As shown in Figure 6, the raised parts of the characters on the surface of the square entertainment tile 1 do not have a rough surface 2, nor do the other five sides. The raised parts of the characters on the surface of the square entertainment tile 1 also do not have a rough surface 2. The rough surface 2 is designed to avoid the characters. Square entertainment tiles 1, i.e., mahjong tiles, are mostly molded using a mold. Uneven grooves with a height / width of 0.5mm are set on the character surface within the mold, and the raised parts on the character surface are avoided; that is, the raised parts on the character surface do not have a rough surface 2. After completion, the material of the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into a square entertainment tile, i.e., mahjong tile, the rough surface 2 is set on the square entertainment tile 1. Thus, the square entertainment tile 1, i.e., mahjong tile, and the rough surface 2 are integrally formed. Mahjong tile processing is existing technology. Refer to a mahjong tile manufacturing method, patent number CN200410006026.3.

[0051] like Figure 2 , 4 As shown in Figure 5, a rough surface 2 is provided on the raised portion of the character surface on the surface of the square entertainment tile 1, while the other five surfaces do not have a rough surface 2. During the design of the rough surface 2, it is provided on the raised portion of the character surface. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are provided on the character surface within the mold, and rough surface grooves are provided on the raised portion of the character surface. After completion, the material of square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into square entertainment tiles, i.e., mahjong tiles, the rough surface 2 is provided on square entertainment tile 1 and designed on the raised portion of the character surface. Thus, square entertainment tile 1, i.e., mahjong tile, and rough surface 2 are integrally formed.

[0052] Continue as Figure 7 As shown, on the surface of the square entertainment tile 1, the character side and the corresponding back side are designed with rough surfaces 2, while the other four sides do not have rough surfaces 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly molded using a mold. Uneven grooves with a height / width of 0.5mm are set in the mold on the character side and the corresponding back side. After completion, the material of the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into the square entertainment tile 1, i.e., mahjong tile, the rough surfaces 2 are set on the character side and the corresponding back side of the square entertainment tile 1. In this way, the square entertainment tile 1, i.e., mahjong tile, and the rough surfaces 2 are integrally formed.

[0053] like Figure 7As shown, the surface of the square entertainment tile 1 has a rough surface 2 designed on the corresponding back side of the character surface. The other four surfaces also have rough surfaces 2, except for the raised parts of the characters on the character surface. Square entertainment tiles 1, i.e., mahjong tiles, are mostly designed using a mold-molded integral design. Within the mold, there are uneven grooves with a height / width of 0.5mm on the character surface and the corresponding back side, as well as uneven grooves with a height / width of 0.5mm on the raised parts of the characters. After completion, the material for the square entertainment tile 1 (mahjong tile) is filled into the mold. After the mold is processed into the square entertainment tile 1 (mahjong tile), the rough surfaces 2 are set on the character surface and the corresponding back side of the character surface, and also designed on the raised parts of the characters. Thus, the square entertainment tile 1 (mahjong tile) and the rough surfaces 2 are integrally molded.

[0054] Continue as Figure 7 As shown, on the surface of the square entertainment tile 1, the character side and the corresponding back side are designed with rough surfaces 2, while the other four sides do not have rough surfaces 2. Specifically, the raised parts of the characters on the character side of the square entertainment tile 1 do not have rough surfaces 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly designed using a mold-molded one-piece molding process. Uneven grooves with a height / width of 0.5mm are set in the mold on the character side and the corresponding back side. After completion, the material of the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into the square entertainment tile 1, i.e., mahjong tile, the rough surfaces 2 are set on the character side and the corresponding back side of the square entertainment tile 1. Thus, the square entertainment tile 1, i.e., mahjong tile, and the rough surfaces 2 are integrally molded.

[0055] like Figure 8-9 As shown, the six sides of the square entertainment tile 1 have roughened surfaces 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are set on the six sides of the mold. After completion, the material for the square entertainment tile 1, i.e., the mahjong tile, is filled into the mold. After the mold is processed into the square entertainment tile 1, i.e., the mahjong tile, the roughened surfaces 2 are set on the square entertainment tile 1. In this way, the square entertainment tile 1, i.e., the mahjong tile, and the roughened surfaces 2 are integrally formed.

[0056] like Figure 8 As shown, rough surfaces 2 are provided on six surfaces of the square entertainment tile 1, with the rough surfaces 2 also provided on the raised parts of the characters on the character surface of the square entertainment tile 1. Square entertainment tiles 1, i.e., mahjong tiles, are mostly designed using a mold-molded one-piece design. Uneven grooves with a height / width of 0.5mm are designed on the six surfaces of the mold, and uneven grooves with a height / width of 0.5mm are also designed on the raised parts of the characters on the character surface. After completion, the material of the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into the square entertainment tile 1, i.e., mahjong tile, the rough surfaces 2 are provided on the square entertainment tile 1 and the raised parts of the character surface. In this way, the square entertainment tile 1, i.e., mahjong tile, and the rough surfaces 2 are integrally molded.

[0057] Continue as Figure 9 As shown, rough surfaces 2 are provided on six sides of the square entertainment tile 1, except for the raised parts of the characters on the character surface of the square entertainment tile 1, which do not have rough surfaces 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly designed for one-piece molding using a mold. Uneven grooves with a height / width of 0.5mm are provided on the six sides of the mold. After completion, the material for the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into the square entertainment tile 1, i.e., mahjong tile, the rough surfaces 2 are set on the square entertainment tile 1. Thus, the square entertainment tile 1, i.e., mahjong tile, and the rough surfaces 2 are integrally molded.

[0058] like Figure 1-9 As shown, the rough surface 2 is an array of grooves, including rectangular grooves. The rectangular groove array is designed on the recessed portion 3. The protrusions between adjacent rectangular grooves are designed in a grid pattern, or the recessed portions between adjacent rectangular grooves are designed in a grid pattern. The grid-like protrusions or recesses between adjacent grooves improve the user's tactile feel. The thickness of the rough surface 2 is preferably 0.3mm. Some users habitually use their ten fingers or thumb to touch and identify the square entertainment card 1. During the touch process, the 0.3mm rough surface 2 improves the user's tactile feel and increases the friction between the rough surface 2 and the fingers, reducing the number of times the square entertainment card 1 slips off. Because the surface of the existing square entertainment card 1 is too smooth, it is easy to slip off during gameplay, which can easily cause the square entertainment card 1 to fall and be damaged.

[0059] Continue as Figure 1-9 As shown, the depth of the groove is 0.1~3mm, preferably 0.3mm. This avoids excessively high protrusions between adjacent grooves, which would affect the user's feel and also hinder the shuffling of the cards by the card sorting machine. Since the thickness of a fingerprint on the surface of a finger is approximately 0.3mm, the depth of the groove 2 on the surface of the square entertainment card 1 is designed to be 0.3mm, thus reducing the number of times the square entertainment card 1 slips off. The width of the protrusion between the grooves is 0.1~3mm, preferably 0.3mm. This design avoids excessively wide protrusions between adjacent grooves, which would affect the user's feel during gameplay. Since the thickness and width of a fingerprint on the surface of a finger are both approximately 0.3mm, the width between adjacent grooves on the character surface of the square entertainment card 1 is 0.3mm, thus reducing the number of times it slips off.

[0060] Continue as Figure 1-9As shown, the rough surface 2 includes multiple grooves spaced apart. The groove array is arranged on the recessed portion, making the graphics on each square entertainment card surface neat and aesthetically pleasing. The raised portions between adjacent grooves improve the user's feel and prevent slippage. The grooves include rectangular grooves. After the rectangular grooves are arranged in an array on the surface of the square entertainment card body, the raised portions between adjacent rectangular grooves have a grid-like design. The grid-like raised portions between adjacent grooves improve the user's feel. The grooves also include linear grooves. The raised portions between adjacent linear grooves have a strip-shaped design, a spiral-shaped design, a circular design, or a straight or curved design. The linear grooves are designed to incorporate fingerprints on the surface of the square entertainment card body, increasing friction between the finger and the card during gameplay to prevent slippage. The groove depth is 0.1~3mm, preferably 0.5mm, to avoid excessively high raised portions between adjacent grooves, which would affect the user's feel and hinder the shuffling of the cards by the card sorting machine. Since the thickness of a fingerprint on the surface of a finger is about 0.5mm, the groove depth on the surface of the square entertainment card is designed to be 0.5mm to prevent it from slipping.

[0061] Continue as Figure 1-9 As shown, the grooves do not include rectangular or linear grooves, but also include point-like geometric shapes, such as any one of the following: cube, cuboid, cylinder, cone, frustum, prism, sphere, pyramid, and polyhedron. The groove depth is controlled between 0.1 and 3 mm, and the protrusion of adjacent geometric grooves is also controlled between 0.1 and 3 mm, preferably 0.3 mm. Different geometric grooves are designed according to user needs, so that the grooves on the surface of the square entertainment card 1 are diverse, or the patterns formed on the protrusions between adjacent grooves are diverse. During the card-laying process, the square entertainment cards 1 are neatly arranged, avoiding an uneven state after laying.

[0062] Continue as Figure 1-9 As shown, the distance between the upper part of the outer edge of the recessed portion 3 and the outer edge of the square entertainment card is 1-5mm, and the distance between the upper part of the outer edge of the recessed portion 3 and the edge of the square entertainment card 1 is 2mm. To avoid damaging the rough surface 2 during the grinding process of the square entertainment card 1, the rough surface 2 is recessed by 0.2mm. This reduces wear on the rough surface 2 during grinding, meaning that the grinding process touches the position where the upper part of the outer edge of the recessed portion 3 is 2mm away from the edge of the square entertainment card 1, thus reducing wear. A 2mm smooth surface is left between the edge of the square entertainment card 1 and the recessed portion, which is beneficial for the card shuffling machine.

[0063] Continue as Figure 1-9As shown, the square entertainment tiles 1, i.e., the mahjong tiles, need to be polished after demolding. During the polishing process, the square entertainment tiles 1, i.e., the mahjong tiles, can easily cause damage to the rough surface 2 due to mutual collision. The rough surface is designed on the recessed part 3, with a depth of 0.1-3mm, preferably 0.5mm. After recessing, the rough surface 2 is less likely to be damaged during polishing. That is, during the polishing process, a 2mm smooth surface is left between the edge of the square entertainment tile 1 and the recessed part for mutual collision, thus reducing damage to the rough surface 2 on the mahjong tiles. Continue as Figure 1-9 As shown, the rough surface is designed on the recessed part 3, which is located on the surface of the square entertainment tile 1. The depth of the recessed part 3 is 0.1-3mm, preferably 0.5mm. This avoids the recessed part 3 being too deep, affecting the user's feel and the shuffling of the tile sorting machine. Maintaining a depth of 0.5mm between the edge of the square entertainment tile 1 and the recessed part facilitates the shuffling of the tile sorting machine and also allows for neat placement on the table. The rough surface 2 easily generates resistance during friction with the tile sorting machine. After the rough surface 2 is recessed, it does not rub against the tile sorting machine. The surface that rubs against the tile sorting machine is the 2mm smooth surface between the edge of the square entertainment tile 1 and the recessed part, thus reducing the frictional resistance between the mahjong tiles and the tile sorting machine.

[0064] Continue as Figure 1-9 As shown, the square entertainment tile 1 has a rough surface 2 designed on its body. A 2mm smooth surface is left between the edge of the square entertainment tile 1 and the recessed portion; that is, the rough surface 2 is not designed on the 2mm smooth surface between the edge of the square entertainment tile 1 and the recessed portion. The rough surface 2 is avoided during the design of the rough surface 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are set in the mold. The 2mm smooth surface between the edge of the square entertainment tile 1 and the recessed portion is not designed with uneven grooves. After completion, the square entertainment tile 1, i.e., mahjong tile material, is filled into the mold. After the mold is processed into square entertainment tiles, i.e., mahjong tiles, the rough surface 2 is set on the square entertainment tile 1, with a 2mm smooth surface left between the edge of the square entertainment tile 1 and the recessed portion. Mahjong tile processing is based on existing technology (see Baidu for mahjong tile processing).

[0065] like Figure 1 , 3 As shown in Figures 5, 6, and 9, a gap 4 is left between the edge of the character on the square entertainment card 1 and the recessed portion 3. This design facilitates user touch; that is, the outer edge of the character is raised, making it easier for the user to touch and recognize, and improving the user's tactile feel. Existing technology uses a parallel design. The gap between the edge of the character on the square entertainment card 1 and the recessed portion 3 is 0.1-1mm, preferably 0.2mm. The gap 4 is kept within 0.2mm to facilitate touch recognition and avoid the gap 4 being too wide, which would affect the user's tactile feel, i.e., affect finger touch. This design facilitates user touch; that is, the outer edge of the character is raised, making it easier for the user to touch and recognize, and improving the user's tactile feel. Existing technology uses a parallel design.

[0066] Continue as Figure 1 , 3 As shown in Figures 5, 6, and 9, a rough surface 2 is designed on the main body of the square entertainment tile 1. A gap 4 is left between the edge of the characters on the square entertainment tile 1 and the recessed portion 3; this gap 4 does not have the rough surface 2 designed on it. The gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is avoided during the design of the rough surface 2. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are set in the mold. The gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 does not have these uneven grooves. After completion, the material of the square entertainment tile 1, i.e., mahjong tile, is filled into the mold. After the mold is processed into square entertainment tiles, i.e., mahjong tiles, the rough surface 2 is set on the square entertainment tile 1, while the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is a smooth surface. Mahjong tile processing is based on existing technology (see Baidu for mahjong tile processing).

[0067] like Figure 2 , 4 As shown in Figures 7 and 8, there is no gap 4 between the edge of the character on the square entertainment card 1 and the recessed part 3. This design facilitates user touch, that is, the groove on the character remains unchanged, which facilitates user touch recognition and improves the user's tactile feel. The existing technology uses a parallel design.

[0068] Continue as Figure 2 , 4 As shown in Figures 7 and 8, a rough surface 2 is designed on the main body of the square entertainment tile 1. A gap 4 is left between the edge of the characters on the square entertainment tile 1 and the recessed portion 3, and the rough surface 2 is designed on this gap 4. During the design of the rough surface 2, a groove with a height / width of 0.5mm is designed on the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. A groove with a height / width of 0.5mm is set inside the mold. After completion, the material of the square entertainment tile 1, i.e., the mahjong tile, is filled into the mold. After the mold is processed into a square entertainment tile, i.e., a mahjong tile, the rough surface 2 is set on the square entertainment tile 1, where the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is the rough surface 2. Mahjong tile processing is based on existing technology (see Baidu search results for mahjong tile processing).

[0069] like Figure 1 , 3As shown in Figures 5, 6, and 9, a gap 4 is left between the edge of the character on the square entertainment card 1 and the rough surface 2. The character and the recessed portion 3 are recessed simultaneously, with a gap 4 between the outer edge of the character and the rough surface 2. This facilitates user identification of the square entertainment card 1 during finger touch, meaning the outer edge of the character is partially smooth, which improves the user's feel, facilitates shuffling by the card sorting machine, and allows for neat placement on the table. This design facilitates user touch; the raised portion on the outer edge of the character facilitates touch identification and improves the user's feel. Existing technology uses a parallel design. The gap between the edge of the character on the square entertainment card 1 and the rough surface 2 is 0.1-1mm, preferably 0.2mm. The gap 4 is kept within 0.2mm to facilitate touch identification and avoid an excessively wide gap 4, which would affect the user's feel, i.e., impair finger touch. This design facilitates user touch; the raised portion on the outer edge of the character facilitates touch identification and improves the user's feel. Existing technology uses a parallel design.

[0070] Continue as Figure 1 , 3 As shown in Figures 5, 6, and 9, the square entertainment tile 1 has a rough surface 2 designed on its body. A gap 4 is left between the edge of the characters on the square entertainment tile 1 and the rough surface 2, but this gap 4 is not designed with a rough surface 2. During the design of the rough surface 2, the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is avoided. Square entertainment tiles 1, i.e., mahjong tiles, are mostly formed using molds. Uneven grooves with a height / width of 0.5mm are set in the mold, but the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is not designed with uneven grooves. After completion, the square entertainment tile 1, i.e., mahjong tile material, is filled into the mold. After the mold is processed into square entertainment tiles, i.e., mahjong tiles, the rough surface 2 is set on the square entertainment tile 1, where the gap 4 between the edge of the characters on the square entertainment tile 1 and the recessed portion 3 is a smooth surface. Mahjong tile processing is based on existing technology (see Baidu for mahjong tile processing).

[0071] like Figure 2 , 4 As shown in Figures 7 and 8, there is no gap 4 between the edge of the character on the square entertainment card 1 and the rough surface 2. This design facilitates user touch, as the grooves on the characters remain unchanged, making it easier for users to identify them by touch and improving the user's tactile feel. Existing technology uses a parallel design.

[0072] Continue as Figure 2 , 4As shown in Figures 7 and 8, a rough surface 2 is designed on the main body of the square entertainment card 1. A gap 4 is left between the edges of the characters on the square entertainment card 1 and the rough surface 2, and this gap 4 is also designed with the rough surface 2. During the design of the rough surface 2, a groove with a height / width of 0.5mm is designed on the gap 4 between the edges of the characters on the square entertainment card 1 and the recessed portion 3. Square entertainment cards 1, i.e., mahjong tiles, are mostly formed using molds. A groove with a height / width of 0.5mm is set inside the mold. After completion, the material of the square entertainment card 1, i.e., the mahjong tile, is filled into the mold. After the mold is processed into a square entertainment card, i.e., a mahjong tile, the rough surface 2 is set on the square entertainment card 1, where the gap 4 between the edges of the characters on the square entertainment card 1 and the recessed portion 3 is the rough surface 2. Mahjong tile processing is based on existing technology (see Baidu search results for mahjong tile processing).

[0073] Not shown in the figure, a tile sorting machine is described, using mahjong tiles as an example, and square entertainment tiles 1 as an example. The square entertainment tiles 1, i.e., the mahjong tiles, are placed into the mahjong machine. After the mahjong machine shuffles the mahjong tiles, it conveys them to the table for entertainment. During the entertainment process, the rough surface 2 is touched by fingers to improve the feel and reduce the number of times the mahjong tiles slip, thereby reducing damage to the mahjong tiles.

[0074] After the mahjong machine shuffles the tiles, the rough surfaces 2 on the surface of the mahjong tiles are arranged in rows or arrays of grooves with a diameter of 0.3mm, allowing the tiles to be neatly arranged on the table. Some users habitually identify the square tiles by touching them with their fingers and thumb; the 0.3mm rough surfaces 2 improve the user's feel during this process, reducing the number of times the tiles slip. Because the grooves on the surface of the square tiles 1 (mahjong tiles) are arranged in an array, there will be no unevenness, ensuring they are neatly arranged on the table. The 0.3mm gap between the raised parts of adjacent grooves on the surface of the mahjong tiles increases the user's feel, i.e., the friction between the hand and the mahjong tiles, reducing the number of slips and minimizing damage to the mahjong tiles.

[0075] Not shown in the image, this is a card-sorting machine, based on the Pai Gow machine. Pai Gow is a traditional Chinese card game made of wood and bone, and its gameplay is more varied and interesting than dice. Pai Gow evolved from dice, but its structure is far more complex. For example, two "sixes" form a "heavenly tile," two "ones" form a "secondary tile," and a "six" and a "five" form a "tiger head." During the Ming and Qing dynasties, pushing and playing Pai Gow were popular and highly attractive games. Mahjong is the most widely played form of dominoes. Both Pai Gow and Mahjong tiles have block-shaped playing surfaces. The surface of Pai Gow is designed with grooves to increase tactile feedback and friction, preventing slippage.

[0076] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
