Description

Technical Field

[0001] This utility model relates to the field of automatic mahjong machine technology, and in particular to the tile-lifting plate and tilting tile-lifting device of an automatic mahjong machine. Background Technology

[0002] The automatic mahjong machine that tilts and dispenses tiles in stages has a sensor on the back of the tile-lifting plate for detecting mahjong tiles. When the sensor detects that the mahjong tiles for the first tile-dispensing stage have been removed from the tile-lifting plate, the automatic mahjong machine proceeds to the second tile-dispensing stage.

[0003] However, because the sensor is separated from the mahjong tile by a tile-lifting plate, a sensor with a larger detection range is required to detect the mahjong tile, which increases the cost of the sensor. Furthermore, increasing the detection range of the sensor can easily lead to false detections, affecting the detection accuracy of the sensor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art by proposing a tile-lifting plate for an automatic mahjong machine, so as to solve the problem of needing to use a sensor with a large detection range on the tile-lifting plate.

[0005] To achieve the above technical objectives, the automatic mahjong machine proposed in this utility model includes a tile-lifting plate, comprising:

[0006] The plate base layer has a first surface extending along its length;

[0007] A bearing layer, which is stacked on the first surface;

[0008] The plate also includes a sensor. An assembly cavity is provided on the plate base layer, and the sensor is mounted in the assembly cavity. A detection hole is provided on the side of the plate base layer near the plate support layer to expose the sensor, so that the sensor is close to the plate support layer.

[0009] In this embodiment, the sensor is mounted in the assembly cavity of the base layer of the plate and close to the tile-bearing layer, thereby reducing the straight-line distance between the sensor and the mahjong tiles on the plate. Consequently, the required detection range of the sensor is reduced, which helps to reduce the cost of the sensor and improve its detection accuracy.

[0010] Preferably, the substrate has a second surface that is spaced apart from the first surface in the thickness direction of the substrate, the assembly cavity forms a second opening on the second surface, the sensor is mounted on the circuit board, and the circuit board is inserted into the assembly cavity through the second opening.

[0011] By adopting the aforementioned technical solution, since the circuit board is inserted into the assembly cavity through the second opening on the second surface of the board base layer, the board base layer does not need to open a large opening on the first surface for assembling the circuit board. This avoids the impact of opening a large opening on the first surface of the board base layer on the support of the first surface for the bearing layer, thus enabling the board base layer to provide better support performance for the bearing layer.

[0012] Preferably, the base plate is provided with buckles on opposite sides of the assembly cavity, and at least one of the buckles is configured as an elastic buckle, so that the circuit board is received in the assembly cavity and locked by the buckles.

[0013] By adopting the aforementioned technical solution, the circuit board can be contained and limited by the assembly cavity of the substrate, improving the installation reliability of the circuit board, and the elastic buckle reduces the difficulty of disassembling and assembling the circuit board, saving labor costs.

[0014] Preferably, the assembly cavity also includes a support for the sensor, wherein the assembly cavity forms a first opening on the first surface, the support extends at least partially into the assembly cavity and forms a support surface adapted to the shape of the first opening, the support surface is close to the bearing layer, and the detection hole is located on the side of the support close to the bearing layer.

[0015] By adopting the aforementioned technical solution, the sensor can be protected by the bracket when it is assembled onto the lifting plate, thus avoiding the probability of damage to the sensor during the assembly process. Furthermore, the bracket's support surface is close to the plate layer, providing certain support to the plate layer and reducing the strength reduction caused by opening assembly holes in the plate base layer.

[0016] Preferably, the supporting surface and the first surface are on the same plane.

[0017] By adopting the aforementioned technical solution, since the supporting surface and the first surface are on the same plane, the supporting surface can support the tile-bearing layer together with the first surface, thereby further improving the support of the tile-raising plate for the mahjong tiles.

[0018] Preferably, the plate base has a second surface that is spaced from the first surface in the thickness direction of the plate base, the assembly cavity forms a second opening on the second surface, the bracket includes a bracket body for accommodating the sensor and a lug extending from the side of the bracket body, the bracket body extends into the assembly cavity from the second opening, the top surface of the bracket body forms the support surface, and the lug is fixedly connected to the plate base.

[0019] By adopting the aforementioned technical solution, the bracket is prevented from being fixedly connected to the base layer of the board on the first surface, thereby avoiding the formation of a fixed structure on the first surface that would affect the support of the first surface for the bearing layer.

[0020] Preferably, the plate base includes a first plate-shaped member and a second plate-shaped member with greater rigidity than the first plate-shaped member. The second plate-shaped member is embedded in or stacked on the first plate-shaped member. The lug is fixedly connected to the plate base by a fastener. The fastener passes through the lug and the first plate-shaped member and is locked to the second plate-shaped member.

[0021] By adopting the aforementioned technical solution, fasteners are used to lock the second plate-shaped member through the lug and the first plate-shaped member. The rigidity of the second plate-shaped member is greater than that of the first plate-shaped member, which avoids damage to the base layer of the plate by the fastener's locking force. Furthermore, by setting the second plate-shaped member with greater rigidity, the strength of the base layer of the plate can be strengthened, thereby improving the support strength of the lifting plate. At the same time, since the rigidity of the first plate-shaped member can be smaller, the material cost of the first plate-shaped member can be reduced, thereby reducing the material cost of the lifting plate.

[0022] Preferably, the first plate-shaped member has a first plane and a groove formed by recessing from the first plane, the second plate-shaped member has a second plane, the second plate-shaped member is fitted into the groove, and the first plane and the second plane are flat and together constitute the first surface.

[0023] Using the aforementioned technical solution, the second plate-shaped member is embedded in the first plate-shaped member, and the second plane of the second plate-shaped member is flush with the first plane of the first plate-shaped member to jointly form the first surface, thereby enabling the first surface of the plate base layer to remain flat and maintain the support of the plate base layer for the bearing layer.

[0024] Preferably, the sensor is electrically connected to the circuit board, the bracket is provided with a cavity and a buckle on opposite sides of the cavity, at least one of the buckles is set as an elastic buckle, and the circuit board is received in the cavity and locked by the buckle.

[0025] Using the aforementioned technical solution, the bracket can accommodate the circuit board, so the sensor and the circuit board do not need to be installed separately, simplifying the assembly process of the plate-raising board. At the same time, the bracket has elastic buckles on at least one side of the cavity, which also reduces the difficulty of disassembling and assembling the circuit board, thereby saving labor costs.

[0026] Preferably, there are multiple sensors, which are spaced apart along the length of the lifting plate; or,

[0027] The sensor is configured as a plurality of sensors, which are spaced apart along the width direction of the plate lifting plate.

[0028] By employing the aforementioned technical solution, multiple sensors are spaced apart along the length of the base layer of the board, increasing the detection range of the sensors on the tile-lifting board and reducing the occurrence of missed detections. Furthermore, even when a small number of mahjong tile stacks are pushed onto the tile-lifting board, they can still be detected by the corresponding sensors, enabling the tile-lifting board to be compatible with automatic mahjong machines with phased tile-loading functions. By distributing the sensors spaced apart along the width of the base layer of the board, the sensors can detect mahjong tiles of different sizes, improving the detection accuracy and precision of the tile-lifting board for mahjong tiles of different sizes, and also avoiding the increased probability of false detections caused by increasing the detection range of a single sensor.

[0029] This utility model also proposes a tilting tile-lifting device for an automatic mahjong machine, including a tile-lifting bracket and a tile-lifting plate of any of the aforementioned technical solutions. One end of the tile-lifting plate is rotatably mounted on the tile-lifting bracket, and the tile-lifting plate swings up and down relative to the tile-lifting bracket.

[0030] Since the card-lifting device of this utility model adopts the card-lifting plate of any of the aforementioned technical solutions, the tilting card-lifting device has all the technical effects of the aforementioned technical solutions.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" or "several" means two or more, unless otherwise expressly defined.

[0053] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0054] like Figures 1 to 5 As shown in the embodiment of this utility model, the tile-lifting plate of the automatic mahjong machine includes a tile-supporting layer 100, a plate base layer 200, and a sensor 300. The plate base layer 200 has a first surface 201 extending along its length, and the tile-supporting layer 100 is stacked on the first surface 201. The plate base layer 200 is provided with an assembly cavity 210, and the sensor 300 is installed in the assembly cavity 210 and close to the tile-supporting layer 100. The side of the plate base layer close to the tile-supporting layer 100 is provided with a detection hole 402 that exposes the sensor 300, so that the sensor 300 is close to the tile-supporting layer 100.

[0055] The first surface 201 is located on the upper side of the substrate 200 and is used to support the tile-supporting layer 100 and the mahjong tiles on the tile-supporting layer 100. The sensor 300 is used to detect the mahjong tiles on the tile-supporting layer 100.

[0056] Mahjong tiles in automatic mahjong machines typically have magnetic cores. In this embodiment, sensor 300 uses a Hall element to detect the magnetic field of the magnetic core.

[0057] In some other embodiments, the sensor 300 may also be a photoelectric sensor, with corresponding light holes provided on the bearing layer 100 and the base layer 200.

[0058] Typically, the material of the tile support layer 100 is the same flexible material as the surface of the automatic mahjong machine, such as velvet.

[0059] In this invention, the sensor 300 is mounted in the assembly cavity 210 of the base layer 200 and close to the tile support layer 100, thereby reducing the straight-line distance between the sensor 300 and the mahjong tiles on the lifting plate. Consequently, the detection range required by the sensor 300 is reduced, which helps to reduce the cost of the sensor 300 and improve its detection accuracy.

[0060] In this embodiment, to increase the strength of the plate base layer 200, the plate base layer 200 includes a first plate-shaped member 220 and a second plate-shaped member 230 with greater rigidity than the first plate-shaped member 220. The top of the first plate-shaped member 220 has a recessed groove 222, into which the second plate-shaped member 230 is fitted. The first plate-shaped member 220 forms an upwardly convex protrusion 223 within the groove 222, and the protrusion 223 is hollow, forming the aforementioned assembly cavity 210. The second plate-shaped member 230 has a clearance hole to avoid the protrusion 223, and at least a portion of the protrusion 223 extends into the clearance hole so that the sensor 300 is mounted in the assembly cavity 210 and close to the bearing layer 100. The first surface 201 is formed by the upper surfaces of the first plate-shaped member 220 and the second plate-shaped member 230. The first surface 201 may also include the top surface of the protrusion 223.

[0061] In some other embodiments, the substrate 200 may also be made of a high-strength material, and the substrate 200 need not be divided into a first plate-shaped member 220 and a second plate-shaped member 230.

[0062] In this embodiment, the tile-lifting plate can swing and move up and down. During the tile-pushing phase, one end of the tile-lifting plate swings down to connect with the tile-pushing slot of the automatic mahjong machine, and the tile-pushing mechanism of the automatic mahjong machine pushes the mahjong tiles onto the tile-lifting plate. During the tile-lifting phase, one end of the tile-lifting plate swings up, and the mahjong tiles rise onto the table of the automatic mahjong machine.

[0063] The tile-raising plate in this embodiment can be used in conventional automatic mahjong machines, such as four-player mahjong machines. When the sensor 300 detects mahjong tiles on the tile-raising plate, the automatic mahjong machine will not perform the tile-pushing and tile-raising action for the second set of mahjong tiles.

[0064] The tile-raising plate in this embodiment can also be used in automatic mahjong machines with a phased tile-raising function, which are typically four-player mahjong machines.

[0065] The phased card-drawing process includes a first card-drawing phase and a second card-drawing phase. In the first card-drawing phase, at least a portion of the mahjong tiles from each of the four players' hands are pushed onto the rising plate, which then raises the tiles from the first card-drawing phase onto the automatic mahjong machine's table. In the second card-drawing phase, the mahjong tile stacks drawn by the four players in turn are raised onto the rising plate, which then raises the tiles from the second card-drawing phase onto the automatic mahjong machine's table. Sensor 300 triggers the second card-drawing phase, or makes the second card-drawing phase triggerable, after detecting that tiles from the first card-drawing phase have been taken by a player.

[0066] In this game, the dealer has 14 tiles, and the other players have 13 tiles each. In the first round, players can either draw 6.5 stacks of tiles, and the dealer then draws one tile from the stacks in the second round; or they can draw 7 stacks; or they can draw 6 stacks, and the players take turns drawing one or two tiles from the stacks in the second round. The remaining stacks in the second round are then filled. The number of tiles in the first round is usually less than in the second round.

[0067] In one embodiment, such as Figure 2 , Figure 5 As shown, the plate base 200 has a second surface 202 that is spaced apart from the first surface 201 in the thickness direction of the plate base 200. The assembly cavity 210 forms a second opening 212 on the second surface 202. The sensor 300 is mounted on the circuit board 500, and the circuit board 500 is inserted into the assembly cavity 210 through the second opening 212.

[0068] Since the circuit board 500 is inserted into the assembly cavity 210 through the second opening 212 on the second surface 202 of the board base 200, the board base 200 does not need to open a large opening on the first surface 201 for assembling the circuit board 500. This avoids the problem of opening a large opening on the first surface 201 of the board base 200, which would affect the support of the first surface 201 for the support layer 100. As a result, the board base 200 can provide better support performance for the support layer 100.

[0069] In one embodiment, such as Figure 2 , Figure 5 As shown, the base plate 200 has snap fasteners on opposite sides of the assembly cavity 210, and at least one of the snap fasteners is set as an elastic snap fastener 440. The circuit board 500 is housed in the assembly cavity 210 and locked by the snap fasteners.

[0070] In this embodiment, the assembly cavity 210 is provided with a fixed buckle 430 and an elastic buckle 440 on opposite sides. One end of the circuit board 500 is limited by the fixed buckle 430, and the other end is limited by the elastic buckle 440. The elastic deformation of the elastic buckle 440 can release the limitation on the circuit board 500, thereby removing one end of the circuit board 500 from the assembly cavity 210; the elastic buckle 440 can also elastically deform during the process of the circuit board 500 being installed into the assembly cavity 210, and elastically reset after the circuit board 500 is installed, thereby limiting one end of the circuit board 500 in the assembly cavity 210.

[0071] In some other embodiments, elastic buckles 440 may be provided on both sides of the assembly cavity 210, and the circuit board 500 can be inserted into or removed from the assembly cavity 210 from either side of the assembly cavity 210.

[0072] The corresponding two sides can be opposite sides of the assembly cavity 210 along the width direction or opposite sides along the length direction.

[0073] With the above settings, the circuit board 500 can be accommodated and limited by the assembly cavity 210 of the substrate, improving the installation reliability of the circuit board 500, and the elastic buckle 440 reduces the difficulty of disassembling and assembling the circuit board 500, saving labor costs.

[0074] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, the lifting plate also includes a bracket 400 that supports the sensor 300. The assembly cavity 21 forms a first opening 211 on the first surface 201. The bracket 400 extends at least partially into the assembly cavity 210 and forms a support surface 401 that adapts to the shape of the first opening 211. The support surface 401 is close to the plate support layer 100. The detection hole 402 is provided on the side of the bracket 400 close to the plate support layer 100.

[0075] The sensor 300 is first installed onto the bracket 400, and the bracket 400 is then installed onto the base layer 200 of the plate to complete the assembly of the sensor 300 and the plate.

[0076] In this way, since the sensor 300 can be supported and protected by the bracket 400 when it is assembled onto the lifting plate, the probability of damage to the sensor 300 during the assembly process is avoided. Furthermore, the support surface 401 of the bracket 400 is close to the plate-bearing layer 100, which can provide certain support for the plate-bearing layer 100 and reduce the strength reduction caused by opening the assembly cavity 210 on the plate base layer 200.

[0077] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, the support surface 401 and the first surface 201 are on the same plane.

[0078] Since the support surface 401 and the first surface 201 are on the same plane, the support surface 401 can support the tile-bearing layer 100 together with the first surface 201, thereby further improving the support of the tile-raising plate for the mahjong tiles.

[0079] In one embodiment, such as Figure 6 , Figures 10 to 12 As shown, the plate base 200 has a second surface 202 that is spaced apart from the first surface 201 in the thickness direction of the plate base 200. The assembly cavity 210 forms a second opening 212 on the second surface 202. The bracket 400 includes a bracket 400 body that houses the sensor 300 and a lug 420 extending from the side of the bracket 400 body. The bracket 400 body extends into the assembly cavity 210 from the second opening 212. The top surface of the bracket 400 body forms a support surface 401. The lug 420 is fixedly connected to the plate base 200.

[0080] The assembly cavity 210 extends from the first opening 211 to the second opening 212. The extension direction of the assembly cavity 210 can be along the thickness direction of the plate base 200, or it can be an inclined extension with an angle to the thickness direction of the plate base 200.

[0081] Since the main body of the bracket 400 extends into the assembly cavity 210 through the second opening 212, the lug 420 is fixedly connected to the base plate 200 on one side of the second surface 202 of the base plate 200.

[0082] With the above settings, the bracket 400 is prevented from being fixedly connected to the base layer 200 of the plate on the first surface 201, thereby avoiding the formation of a fixed structure on the first surface 201 that would affect the support of the first surface 201 for the plate layer 100.

[0083] In one embodiment, based on the card-raising board of the foregoing embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 11 , Figure 12 As shown, the plate base 200 includes a first plate-shaped member 220 and a second plate-shaped member 230 with greater rigidity than the first plate-shaped member 220. The second plate-shaped member 230 is embedded in or stacked on the first plate-shaped member 220. The lug 420 is fixedly connected to the plate base 200 by a fastener 240. The fastener 240 passes through the lug 420 and the first plate-shaped member 220 and is locked to the second plate-shaped member 230.

[0084] The second plate-shaped member 230 is used to connect the fasteners 240 and to strengthen the overall strength of the plate base 200. The assembly cavity 210 may or may not penetrate the second plate-shaped member 230; that is, the horizontal projections of the second plate-shaped member 230 and the assembly cavity 210 may overlap, may not overlap, or may at least partially overlap.

[0085] The first plate-shaped member 220 is made of plastic. The second plate-shaped member 230 can be made of rigid plastic or rigid metal. The second plate-shaped member 230 has high rigidity and can withstand the locking force of the fastener 240, preventing it from being damaged under the locking force.

[0086] In some embodiments, the first plate-shaped member 220 may be formed by ultrasonic welding of an upper member and a lower member overlapping each other, the second plate-shaped member 230 is embedded between the upper member and the lower member, and the first surface 201 is formed on the upper side of the upper member.

[0087] In some other embodiments, the first plate member 220 may have an insert groove, the second plate member 230 may be embedded in the insert groove, and the first surface 201 may be formed on the first plate member 220 and the second plate member 230.

[0088] In some other embodiments, the first plate-shaped member 220 and the second plate-shaped member 230 may overlap vertically, with the first surface 201 formed on the top of the second plate-shaped member 230.

[0089] Fastener 240 is used to fasten the lug 420 and the first plate member 220 to the second plate member 230. The rigidity of the second plate member 230 is greater than that of the first plate member 220, which avoids damage to the plate base 200 by the fastening force of the fastener 240. Furthermore, by setting the second plate member 230 with greater rigidity, the strength of the plate base 200 can be strengthened, and the support strength of the lifting plate can be improved. At the same time, since the rigidity of the first plate member 220 can be smaller, the material cost of the first plate member 220 can be reduced, thereby reducing the material cost of the lifting plate.

[0090] In this embodiment, the fastener 240 is a screw.

[0091] In one embodiment, based on the card-raising board of the foregoing embodiments, such as Figures 7 to 9 As shown, the first plate-shaped member 220 has a first plane 221 and a groove 222 formed by recessing from the first plane 221, and the second plate-shaped member 230 has a second plane 231. The second plate-shaped member 230 is fitted into the groove 222. The first plane 221 and the second plane 231 are flat and together constitute the first surface 201.

[0092] The first plane 221 is located on the upper side of the first plate-shaped member 220, and the second plane 231 is the top surface of the second plate-shaped member 230.

[0093] In this embodiment, the assembly cavity 210 is located in the groove 222. The first plate-shaped member 220 is provided with a first assembly hole 224, and the second plate-shaped member 230 is provided with a second assembly hole 232. The first assembly hole 224 and the second assembly hole 232 are connected and cooperate with the plate base layer 200 and the bearing layer 100 to form the assembly cavity 210.

[0094] In other embodiments, two second plate-shaped members 230 may be provided, with the two second plate-shaped members 230 spaced apart along the width direction of the plate base 200. Lugs 420 are provided on both sides of the bracket 400 body along the width direction of the plate base 200, so that the fasteners 240 can pass through the lugs 420 and the first plate-shaped member 220 and be locked onto the second plate-shaped members 230. In this way, two grooves 222 may be provided, with the two grooves 222 provided on both sides of the assembly cavity 210 along the width direction of the plate base 200. The assembly cavity 210 passes through the first plate-shaped member 220, and the second plate-shaped members 230 are located on both sides of the assembly cavity 210.

[0095] In this embodiment, the second plate-shaped member 230 is embedded in the first plate-shaped member 220, and the second plane 231 of the second plate-shaped member 230 is flush with the first plane 221 of the first plate-shaped member 220 to jointly form the first surface 201, thereby enabling the first surface 201 of the plate base 200 to remain flat and maintain the support of the plate base 200 for the plate layer 100.

[0096] In one embodiment, such as Figure 6 , Figure 11 , Figure 12 As shown, the sensor 300 is electrically connected to the circuit board 500. The bracket 400 is provided with a cavity 403 and a buckle on opposite sides of the cavity 403. At least one of the buckles is set as an elastic buckle 440. The circuit board 500 is housed in the assembly cavity 210 and locked by the buckle.

[0097] In this embodiment, a fixed latch 430 and an elastic latch 440 are respectively provided on opposite sides of the cavity 403. One end of the circuit board 500 is limited between the cavity 403 and the fixed latch 430, and the other end is limited between the cavity 403 and the elastic latch 440. The elastic latch 440 can elastically deform, allowing the circuit board 500 to be installed into the cavity 403, or allowing one end of the circuit board 500 to disengage from the limiting position, thus allowing the circuit board 500 to be removed from the cavity 403. The elastic latch 440 can elastically reset, thereby limiting one end of the circuit board 500 in the cavity 403.

[0098] In some other embodiments, elastic latches 440 may be provided on both sides of the cavity 403, and the circuit board 500 can be inserted into or removed from the cavity 403 from either side of the cavity 403.

[0099] With the above configuration, the bracket 400 can accommodate the circuit board 500, so the sensor 300 and the circuit board 500 do not need to be installed separately, simplifying the assembly process of the plate lifter. At the same time, the elastic buckle 440 provided on at least one side of the recess 403 on the bracket 400 also reduces the difficulty of disassembling and assembling the circuit board 500, thereby saving labor costs.

[0100] In one embodiment, based on the card-raising board of the foregoing embodiments, such as Figure 6 , Figure 7 , Figure 11 As shown, at least two sensors 300 are provided on the bracket 400, and the at least two sensors 300 are distributed at intervals along the length of the base plate 200.

[0101] In this embodiment, four sensors 300 are provided, and the four sensors 300 are distributed at intervals along the length direction of the base layer 200 of the plate.

[0102] In some other embodiments, the sensor 300 may also be two, three, five or more.

[0103] By arranging multiple sensors 300 at intervals along the length of the base layer 200, the detection range of the sensors 300 on the tile-lifting plate is increased, reducing the occurrence of missed detections by the sensors 300; furthermore, when a small number of mahjong tile stacks are pushed onto the tile-lifting plate, they can also be detected by the corresponding sensors 300, enabling the tile-lifting plate to be adapted to automatic mahjong machines with phased tile-loading functions.

[0104] In one embodiment, based on the card-raising board of the foregoing embodiments, such as Figure 6 , Figure 7 , Figure 11 As shown, at least two sensors 300 are provided on the bracket 400, and the at least two sensors 300 are spaced apart in the width direction of the base plate 200.

[0105] In this embodiment, four sensors 300 are provided, with two sensors 300 forming a group. One group is located on the left side of the plate base layer 200, and the other group is located on the right side of the plate base layer 200, so that the multiple sensors 300 are distributed at intervals along the width direction of the plate base layer 200.

[0106] In some other embodiments, the sensor 300 may also be distributed in other ways.

[0107] Because mahjong tiles of different sizes have different lengths and widths, and the magnetic core of the mahjong tile is usually located in the center of the tile, the detection position of mahjong tiles of different sizes on the tile-raising plate varies.

[0108] By distributing the sensors 300 at intervals along the width of the base layer 200, the sensors 300 can detect mahjong tiles of different sizes, improving the detection accuracy and precision of the tile-raising plate for mahjong tiles of different sizes, and avoiding the increase in the probability of false detection caused by increasing the detection range of a single sensor 300.

[0109] This utility model also proposes an inclined tile-loading device for an automatic mahjong machine, including a tile-lifting bracket 400 and a tile-lifting plate in any of the aforementioned embodiments. One end of the tile-lifting plate is rotatably mounted on the tile-lifting bracket 400, and the tile-lifting plate swings up and down relative to the tile-lifting bracket 400.

Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
