Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines, and particularly relates to a double-tile-raising mode mahjong machine and a tile-raising mechanism thereof. Background Art

[0002] Based on the number of slots for raising the tiles, current fully automatic mahjong machines can be divided into four-slot mahjong machines and double-slot mahjong machines. As the name suggests, a four-slot mahjong machine has only one slot for raising the tiles on each side, while a double-slot mahjong machine has two slots for raising the tiles on each side.

[0003] In a four-slot mahjong machine, after the tiles are raised to the table, the player must pick up a number of tiles in sequence. In a double-slot machine, however, the tiles that are placed on the table from the slot closest to the player are the deal tiles, while the tiles that are placed on the table from the slot closest to the center of the machine are the draw tiles. This allows players to start the game directly without having to manually pick up tiles; they can simply pick up the deal tiles.

[0004] Although the eight-mouth mahjong machine's card-free feature is more popular, the four-mouth mahjong machine also has a large audience, but the current eight-mouth mahjong machine is not compatible with the four-mouth mahjong machine gameplay. Utility Model Content

[0005] The invention aims to provide a double-upgrading mode mahjong machine and a mahjong upgrading mechanism thereof, wherein the mahjong upgrading mechanism can switch the number of activated mahjong upgrading ports according to the needs of playing cards.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution of the present utility model is as follows:

[0007] A card-raising mechanism for a double-card-raising mode mahjong machine, the card-raising mechanism comprising:

[0008] A first tile raising board, the first tile raising board being close to the edge of the mahjong machine;

[0009] a second card raising board, the second card raising board being close to the center of the mahjong machine;

[0010] The first card-lifting plate has eight machine working positions that rise and fall synchronously with the second card-lifting plate, and four machine working positions that maintain a horizontal state.

[0011] In the present invention, the first tile raising board near the edge of the mahjong machine has two working states. On the eight-slot machine working position, the first tile raising board and the second tile raising board rise and fall together, wherein the first tile raising board is used to deliver the dealing sequence to the tabletop, while the second tile raising board is used to deliver the drawing sequence to the tabletop; on the four-slot machine working position, the first tile raising board remains in a horizontal state flush with the tabletop, and all mahjong tiles are delivered to the tabletop from the second tile raising board; in this way, the playing needs of multiple audiences can be met simultaneously in one mahjong machine.

[0012] The first card raising plate and the second card raising plate can be driven by different card raising drive assemblies. In this case, the card raising drive assembly of the first card raising plate can be controlled separately according to the needs of playing cards. However, in order to save power, only one card raising drive assembly is used in the present invention.

[0013] At this time, as a preference, the card-raising mechanism further comprises:

[0014] A lifting drive assembly, wherein the second lifting plate is driven to rise and fall by the lifting drive assembly;

[0015] A linkage component is used to establish a linkage relationship between the first card-lifting plate and the second card-lifting plate and to make the first card-lifting plate and the second card-lifting plate rise and fall synchronously under the eight-mouth machine working position;

[0016] The card-raising mode switching component is used to disconnect the linkage relationship between the first card-raising board and the second card-raising board in the four-port machine working position.

[0017] In the present invention, the linkage relationship constructed by the linkage component between the first card raising plate and the second card raising plate is not very strong. When the card raising mode switching component is not enabled, the linkage relationship can bring the first card raising plate up and down synchronously when the second card raising plate is raised or lowered; but when the card raising mode switching component is enabled, the linkage relationship is disconnected, which makes the first card raising plate remain in its original position when the second card raising plate descends.

[0018] There are various types of linkage relationships that can be disconnected. Those skilled in the art can arbitrarily choose a linkage component to implement it. The most common one is magnetic connection, that is: the linkage component includes at least one magnetic part and at most one metal part, and two magnetic parts with opposite magnetic poles or a magnetic part and a metal part are respectively arranged on the second lifting board and the first lifting board.

[0019] Based on the above linkage assembly, those skilled in the art can independently develop a variety of card-raising mode switching assemblies capable of disconnecting the linkage relationship between the first card-raising plate and the second card-raising plate, and the present invention has no special requirements for this. As an example, as a preference, in the above-mentioned card-raising mechanism, the card-raising mode switching assembly includes a swing arm, which is movably connected to the mahjong machine and is driven by the driving unit to swing;

[0020] On the four-mouth machine working position, the swing arm moves to the bottom of the first card lifting board and supports the first card lifting board from the bottom; on the eight-mouth machine working position, the swing arm moves to the side of the first card lifting board to avoid the lifting path of the first card lifting board.

[0021] After the swing arm supports the first card raising board, the first card raising board can be flush with the table top, or can be slightly lowered but not to the bottom; it is obviously more preferred to be flush with the table top.

[0022] As a further preferred embodiment, in the above-mentioned card-raising mechanism, the swing arm is in direct contact with the first card-raising plate, or is in contact with the first card-raising plate via a top rod erected on the swing arm;

[0023] The swing arm includes a hinge point and a long arm end and a short arm end on both sides of the hinge point, the push rod is provided at the long arm end, and the short arm end is connected to the drive unit; or the drive unit is provided at the hinge point;

[0024] Alternatively, the hinge point and the push rod are respectively located at two ends of the swing arm, and the drive unit is arranged at the hinge point.

[0025] When the distance between the swing arm and the first card-raising plate is close, the swing arm can support the first card-raising plate from the bottom; when there is a large height difference between the swing arm and the first card-raising plate, it is necessary to erect a top rod on the swing arm to use the top rod to support the first card-raising plate.

[0026] The hinge point between the swing arm and the mahjong machine can be at the end of the swing arm or at an eccentric position. However, in order to make the swing arm produce a larger swing amplitude with minimal force, it is preferred to set the contact position of the top rod or the swing arm and the first card raising plate farther away from the hinge point, that is, at the end of the long arm; obviously, when the top rod and the hinge point are respectively at the two ends of the swing arm, the top rod is also equivalent to being at the end of the long arm.

[0027] At this time, the driving unit for driving the swing arm to swing can be a circumferential drive provided at the hinge point, or a linear drive provided at the end of the short arm.

[0028] The utility model provides a driving unit comprising a lever slidably mounted on a mahjong machine, one end of the lever being movably connected to a short arm end, and the other end of the lever being provided with a sensing module, the sensing module being used to sense whether a card dealing sequence to be sent to a first card raising board is stored in a card storage channel;

[0029] When the sensing module senses that the card dealing sequence is stored in the card storage channel, the lever slides relative to the mahjong machine, thereby driving the swing arm to swing to the eight-slot machine working position; otherwise, the swing arm remains in the four-slot machine working position;

[0030] At this point, the perception module also has multiple options:

[0031] First, a first elastic structure is provided at the hinge point or at the connection between the lever and the swing arm, causing the swing arm to have a tendency to move toward the bottom of the first card raising plate. The sensing module is a probe extending into the card storage channel. When the eight-card machine is in the working position, the probe is squeezed by the card dealing sequence, causing the lever to apply a reaction force to the swing arm to offset the movement tendency.

[0032] Secondly, the sensing module includes an infrared detector or a magnetic sensor, and the shift rod is connected to the linear drive. The infrared detector or magnetic sensor and the linear drive are both connected to a control element, which is used to control the operation of the linear drive according to the output signal of the infrared detector or magnetic sensor.

[0033] As a further preference, in the above-mentioned card-lifting mechanism, the side of the probe facing the card storage channel is an arc-shaped surface that is convenient for the card dealing sequence to pass over, and in the eight-mouth machine working position, the arc-shaped surface contacts at least one mahjong tile.

[0034] The curved surface not only does not hinder the progress of the dealing sequence, but its larger span enables it to contact more mahjong tiles, so that the lever receives the squeezing force from multiple mahjong tiles, making it easier to overcome the inherent movement tendency of the swing arm.

[0035] In a mahjong machine with a 360° rotating push rod, after pushing a mahjong tile onto the lifting plate, the push rod returns to its starting point from the bottom of the lifting plate. The push rod, located below the first lifting plate, is in the path of the push rod. Therefore, in the aforementioned lifting mechanism, the push rod is hingedly connected to the swing arm. The push rod has a supporting position, where it stands upright on the swing arm and supports the first lifting plate, and a retracting position, where it rotates relative to the swing arm to avoid passing mahjong machine actuators (including the push rod).

[0036] A second elastic structure is provided between the push rod and the swing arm, which enables the push rod to move toward the supporting position;

[0037] The push rod is formed with a wedge surface for facilitating the passage of the mahjong machine actuator;

[0038] The push rod at the supporting position supports the first card raising plate at the free end of the first card raising plate.

[0039] When the card-loading push rod runs to the position of the push rod, pressure will be applied to the push rod from the wedge surface, causing the push rod to move from the supporting position to the avoidance position. After the card-loading push rod passes, the push rod will automatically return to the supporting position under the action of the second elastic structure.

[0040] It is foreseeable that when the dealing sequence is sent to the first card raising board, the swing arm and the push rod are also in the four-mouth machine working position, that is, the swing arm and the push rod are normally supporting the first card raising board. Setting the force application position of the push rod or the swing arm to the free end of the first card raising board is conducive to breaking the linkage between the first card raising board and the second card raising board with relatively small force, and it also provides a new lifting point for the first card raising board in a horizontal state, ensuring that the free end of the first card raising board will not collapse when subjected to force (from the table).

[0041] The utility model also provides a double-tile-raising mode mahjong machine, which comprises a frame, and each side of the frame is provided with the above-mentioned tile-raising mechanism.

[0042] Preferably, the double-up mode mahjong machine further includes a card storage mechanism, which includes:

[0043] A card storage device is provided with a card storage channel recessed therein. The card storage channel has a card inlet, a first card outlet, and a second card outlet. The main channel connecting the card inlet and the second card outlet is located at a lower position. The first card outlet is connected to the main channel via a branch channel located at a higher position. The branch channel is used to store the card dealing sequence under the working position of the eight-card machine;

[0044] A card distributor is formed with a guide surface for guiding the card dealing sequence into the branch channel, the guide surface extending from the outer wall of the main channel across the main channel and along the outer wall of the branch channel;

[0045] The card storage channel is arc-shaped, the main channel is located on the outside, and the branch channel is located on the inside; the first card outlet and the second card outlet of the same card storage channel are located on the same side of the mahjong machine.

[0046] In accordance with the above-mentioned tile raising mechanism, the tile storage mechanism in the mahjong machine of the present invention also has two working modes: in the eight-mouth machine working mode, the first tile outlet is used to deliver a dealing sequence (composed of the top one or two layers of mahjong tiles of all tile piles stored in the main channel) to the first tile raising board, while the second tile outlet is used to deliver a drawing sequence (composed of the bottom two layers of mahjong tiles of all tile piles stored in the main channel (71d)) to the second tile raising board. In the four-mouth machine working mode, the first tile outlet is not used, all mahjong tiles are stored in the main channel (the tile pile height is reduced), and only the second tile outlet is used to deliver tiles to the second tile raising board; at this time, all mahjong tiles can be delivered to the second tile raising board at one time, and the player can grab the dealing sequence by himself; or the tiles can be delivered in batches, that is, a number of tile piles at the front of the queue are first delivered to the table as the dealing sequence, and after the player takes the dealing sequence, the remaining tile piles are delivered to the table as the drawing sequence.

[0047] It can be seen that the reason why it is compatible with the above two working modes is that the utility model sets the main channel at a low place and the branch channel at a high place, so that the card dealing sequence can be selectively entered into the branch channel and sent to the first card raising board; at the same time, the sensing module can also easily sense the card dealing sequence at the top layer of the card pile, and the card raising mode switching component can respond quickly.

[0048] Compared with the prior art, the technical effects of the present invention are embodied in:

[0049] (1) The first card raising board near the edge of the mahjong machine in the present invention has two working states. On the eight-slot machine working position, the first card raising board and the second card raising board rise and fall together, wherein the first card raising board is used to deliver the card dealing sequence to the table, while the second card raising board is used to deliver the card drawing sequence to the table; on the four-slot machine working position, the first card raising board remains in a horizontal state flush with the table, and all mahjong tiles are delivered to the table from the second card raising board; in this way, the playing needs of multiple audiences can be met simultaneously in one mahjong machine.

[0050] (2) The utility model uses a probe to sense whether a card dealing sequence is stored in the card storage channel. When the probe senses the card dealing sequence, it drives the lever to slide, and then drives the swing arm to swing, so that the working state of the first card raising board can be controlled very simply and sensitively.

[0051] (3) The utility model sets the force application position of the push rod or the swing arm to the free end of the first card raising board. On the one hand, it is conducive to disconnecting the linkage relationship between the first card raising board and the second card raising board with minimal force. On the other hand, it can provide a new lifting point for the first card raising board in a horizontal state, ensuring that the free end of the first card raising board will not collapse when subjected to force (from the desktop).

[0052] (4) In the mahjong machine of the present invention, both the card storage mechanism and the card promotion mechanism are compatible with a variety of mahjong playing methods, and the two are very compatible. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0060] Example 1

[0061] like Figure 1 and Figure 2 As shown, the present embodiment is a double-elevation mode mahjong machine's elevation mechanism, comprising a first elevation board 1 and a second elevation board 2. The first elevation board 1 and the second elevation board 2 are both hinged to the frame 9 and are roller coaster-type slope elevation boards.

[0062] Among them, the first card-raising board 1 is located close to the edge of the mahjong machine, and the second card-raising board 2 is located close to the center of the mahjong machine; in this embodiment, the first card-raising board 1 and the second card-raising board 2 can be driven by the same card-raising drive component 3, or they can be driven by their own card-raising drive components 3; similarly, the first card-raising board 1 and the second card-raising board 2 at the four sides of the mahjong machine can be driven by the same card-raising drive unit, or they can be driven by their own card-raising drive components 3, and the present invention has no special requirements for this.

[0063] However, in order to save power and ensure that the first card-raising board 1 and the second card-raising board 2 of each party work in the same frequency, in this embodiment, a card-raising drive component 3 is used to simultaneously drive the second card-raising boards 2 on the four sides of the mahjong machine, and the first card-raising board 1 of each party is linked to the corresponding second card-raising board 2 through a linkage component 4.

[0064] The solution of using a card-raising drive component 3 to simultaneously drive the second card-raising plates 2 located on the four sides of the mahjong machine has been described in the patent holder's previous patent documents and will not be repeated in this embodiment.

[0065] like Figure 2 As shown, in this embodiment, the linkage assembly 4 includes a magnetic member 41 disposed at the bottom of the first card-lifting plate 1 and a metal member 42 disposed at the bottom of the second card-lifting plate 2. The metal member 42 is attracted by the magnetic member 41, thereby connecting the first card-lifting plate 1 and the second card-lifting plate 2, forming a linkage relationship. Obviously, the same effect can be achieved by swapping the metal member 42 and the magnetic member 41, or replacing the metal member 42 with another magnetic member 41.

[0066] Obviously, the linkage between the first and second card-raising plates 1 and 2 by the linkage assembly 4 is not very strong. When the second card-raising plate 2 descends while the first card-raising plate 1 remains flush with the tabletop, the linkage between the two is disconnected. This results in the first card-raising plate 1 having two working states: an eight-port machine working position and a four-port machine working position.

[0067] On the eight-mouth machine working position, the first card raising board 1 and the second card raising board 2 rise and fall together, wherein the first card raising board 1 is used to deliver the dealing sequence to the table, while the second card raising board 2 is used to deliver the drawing sequence to the table; on the four-mouth machine working position, the first card raising board 1 remains in a horizontal state flush with the table, and all mahjong tiles are delivered to the table from the second card raising board 2 (all can be delivered at once, or delivered in two times, that is, several piles of tiles at the front of the queue are first delivered to the table as the card raising sequence, and after the player takes the dealing sequence, the remaining piles of tiles are delivered to the table as the drawing sequence); in this way, the gameplay needs of multiple audiences can be met simultaneously in one mahjong machine.

[0068] like Figure 3 As shown, this embodiment uses a card-raising mode switching component 5 to change the working state of the first card-raising plate 1. The card-raising mode switching component 5 includes a swing arm 51, which includes a hinge point 51a that is movably connected to the base 52 or other components of the mahjong machine, and a long arm end 51b and a short arm end 51c on both sides of the hinge point 51a. The short arm end 51c is connected to a drive unit (the drive unit is a linear drive structure) to drive the swing arm 51 to swing; in this case, the drive unit (in this case, the drive unit is a circumferential drive structure) can also be connected to the hinge point 51a. Obviously, the hinge point 51a can also be directly set at the end of the swing arm 51, in which case the drive unit (also a circumferential drive structure) is connected to the hinge point 51a.

[0069] When the long arm end 51b of the swing arm 51 swings below the first card raising board 1, it can prevent the first card raising board 1 from descending. When the height difference between the swing arm 51 and the first card raising board 1 is small, the long arm end 51b can directly contact the first card raising board 1. When the height difference between the swing arm 51 and the first card raising board 1 is large, a push rod 53 can be erected at the long arm end 51b to support the first card raising board 1.

[0070] This embodiment is described by taking the short arm end 51c connected to the drive unit as an example. Figure 3 As shown, the driving unit includes a shifting rod 54 , which is slidably mounted on the base 52 , one end of the shifting rod 54 is movably connected to the short arm end 51 c , and the other end is provided with a probe 55 .

[0071] like Figure 4 As shown, the width of the probe 55 is greater than the width of the lever 54 and extends into the card storage channel of the mahjong machine; when a card dealing sequence with a height equivalent to that of the probe 55 is stored in the card storage channel, the card dealing sequence will squeeze the probe 55, thereby driving the lever 54 to slide, and then driving the swing arm 51 to swing, so that the swing arm 51 and the top rod 53 move to the side and lower part of the first card raising plate 1. At this time, the first card raising plate 1 can be synchronously lowered with the second card raising plate 2.

[0072] Obviously, when there is no card dealing sequence at the same height as the probe 55 in the card storage channel (there are two situations: no cards have been deposited, or cards have been deposited but have been sent to the first card raising plate 1), the probe 55 cannot sense the pressure from the card dealing sequence; at this time, in order to enable the swing arm 51 to automatically return to the center, it is necessary to set a first elastic structure (such as a torsion spring) at the connection position between the lever 54 and the swing arm 51 or at the hinge point 51a of the swing arm 51, so that the swing arm 51 has a tendency to move toward the bottom of the first card raising plate 1.

[0073] like Figure 3 As shown, in this embodiment, the side of the probe 55 facing the card storage channel is an arcuate surface 55a that facilitates the card dealing sequence to pass over. The arcuate surface 55a not only does not hinder the progress of the card dealing sequence, but also its larger span enables it to contact more mahjong tiles, so that the lever 54 can receive the squeezing force from multiple mahjong tiles, making it easier to overcome the inherent movement tendency of the swing arm 51.

[0074] Depend on Figure 3 and Figure 4 It can be seen that in a mahjong machine in which the card-loading push rod 81 rotates 360 degrees, the card-loading push rod 81 will return to the starting point from the bottom of the card-lifting plate after pushing the mahjong tiles onto the card-lifting plate, and the push rod 53 located under the first card-lifting plate 1 is located on the running path of the card-loading push rod 81. In order to prevent the push rod 53 from interfering with the return of the card-loading push rod 81 to the starting point, the push rod 53 is hinged to the swing arm 51 (e.g., using a hinge) in this embodiment. The push rod 53 has a supporting position in which it stands upright on the swing arm 51 and supports the first card-lifting plate 1, and a avoiding position in which it rotates relative to the swing arm 51 to avoid the card-loading push rod 81. In addition, a second elastic structure (e.g., a torsion spring) is provided between the push rod 53 and the swing arm 51 to cause the push rod 53 to move toward the supporting position.

[0075] When the card-loading push rod 81 reaches the position of the push rod 53, it applies pressure to the push rod 53 from the wedge surface 53a, causing the push rod 53 to move from the supporting position to the avoiding position. After the card-loading push rod 81 passes, the push rod 53 automatically returns to the supporting position under the action of the second elastic structure. Obviously, when the card-loading push rod 81 returns to the starting point along the original path after completing the card-loading action, the push rod 53 can be fixed to the swing arm 51.

[0076] It is conceivable that after the card dealing sequence is sent to the first card raising board 1, the swing arm 51 and the push rod 53 are also in the four-mouth machine working position, that is, the normal state of the swing arm 51 and the push rod 53 is to support the first card raising board 1. In this embodiment, the force application position of the push rod 53 or the swing arm 51 is set to the free end of the first card raising board 1. On the one hand, it is conducive to disconnecting the linkage relationship between the first card raising board 1 and the second card raising board 2 with minimal force. On the other hand, it can provide a new lifting point for the first card raising board 1 in a horizontal state, ensuring that the free end of the first card raising board 1 will not collapse when subjected to force (from the table).

[0077] The working principle of the card raising mechanism of a double-raising mode mahjong machine in this embodiment is as follows:

[0078] When a card dealing sequence of the same height as the probe 55 is stored in the card storage channel, the card dealing sequence will apply a reaction force to the probe 55 when passing over the curved surface 55a. This reaction force is sufficient to overcome the elastic tendency of the first elastic structure, causing the lever 54 to slide, thereby causing the swing arm 51 to swing, and the long arm end 51b to move from the bottom of the first card raising plate 1 to the lower side of the first card raising plate 1; at this time, the card raising drive unit is started, driving the second card raising plate 2 to descend, and under the action of the linkage component 4, the first card raising plate 1 also descends, and the card dealing sequence and the card drawing sequence are then respectively raised from the first card raising plate 1 and the second card raising plate 2 to the table top. This is the eight-mouth machine mode;

[0079] When the card-loading push rod 81 completes the card-loading action and is about to return to the starting point from under the first card-lifting plate 1, the card-loading push rod 81 encounters the push rod 53 and applies pressure to the push rod 53 from the wedge surface 53a, causing the push rod 53 to flip around the swing arm 51. After the card-loading push rod 81 passes, the push rod 53 returns to its original position under the action of the second elastic structure and continues to play the role of supporting the first card-lifting plate 1;

[0080] When there is no dealing sequence at a height equivalent to the probe 55 stored in the card storage channel, the swing arm 51 remains below the first card raising plate 1 driven by the first elastic structure, and the top rod 53 lifts the first card raising plate 1 from the bottom to keep it flush with the table top; when the card raising drive unit starts and drives the second card raising plate 2 to descend, due to the support of the top rod 53, the connection between the magnetic part 41 and the metal part 42 is disconnected, and all the mahjong tiles in the card storage channel will be lifted from the second card raising plate 2 to the table top. This is the four-slot machine mode.

[0081] Example 2

[0082] like Figure 4 As shown, the present embodiment is a double-lifting mode mahjong machine, comprising a frame 9, each side of the frame 9 is provided with a card loading system, such as Figure 5 and Figure 6 As shown, the card loading system includes a stacking mechanism 6, a card storage mechanism 7, a card loading mechanism 8, and a card raising mechanism. The stacking mechanism 6 is used to stack the tile piles and store the tile piles one by one in the card storage mechanism 7, the card storage mechanism 7 is used to store the tile piles, the card loading mechanism 8 is used to deliver the tile piles to the card outlet, and the card raising mechanism is used to deliver the mahjong tiles to the table. The card raising mechanism is the same as that in Example 1.

[0083] like Figure 5 and Figure 6As shown, in this embodiment, the card storage mechanism 7 includes a card storage device 71, and a card storage channel is recessed in the main body of the card storage device 71. The card storage channel is arc-shaped and has a card input port 71a and two card output ports: a first card output port 71b and a second card output port 71c. These two card output ports are on the same side of the mahjong machine and are respectively connected to the first card raising plate 1 and the second card raising plate 2.

[0084] The second card outlet 71c is directly connected to the card inlet 71a through the main channel 71d. Relatively speaking, the main channel 71d is located at a lower position on the outside; while the first card outlet 71b is connected to the card inlet 71a by being connected to the main channel 71d. The branch channel 71e connects the main channel 71d and the first card outlet 71b and is only used to transport the card dealing sequence. It can be seen that, relatively speaking, the branch channel 71e is located at a higher position on the inside.

[0085] In this embodiment, at the card inlet 71a, the piles of tiles stored in the main channel 71d are all three-layer or four-layer piles. Among these piles, the mahjong tiles in the lower two layers are always in the main channel 71d, that is, they constitute a card drawing sequence, and the mahjong tiles in the top layer or two layers will enter the branch channel 71e downstream to constitute a card dealing sequence; the probe 55 is inserted into the space where the branch channel 71e is located.

[0086] In this embodiment, the separation of the card dealing sequence and the card drawing sequence is guided by the card distributor 72. The outer side 72a of the card distributor 72 is detachably connected to the card storage 71, thereby providing an outer side wall for the main channel 71d together with the card storage 71; the inner side of the card distributor 72 is formed with a guide surface 72b, the starting end of the guide surface 72b is close to the card inlet 71a, and the terminal end extends to the first card outlet 71b after crossing the main channel 71d; the card dealing sequence advances along the guide surface 72b and is led by the guide surface 72b to the first card outlet 71b.

[0087] Therefore, when the piles of cards stored in the card storage channel are three or four layers, two queues of card drawing sequence and card dealing sequence will be formed and raised to the table. This is the eight-mouth machine playing method under the eight-mouth machine mode; when the piles of cards stored in the card storage channel are two layers, these two-layer card piles will only be in the main channel 71d and will not enter the branch channel 71e. This is the four-mouth machine mode.

[0088] In the four-slot machine mode, all the piles can be raised to the table at once, which is the traditional four-slot machine gameplay; or the piles at the front of the queue can be used as the dealing sequence, and the remaining piles as the drawing sequence, and are delivered to the table in batches, which is the eight-slot machine gameplay in the four-slot machine mode.

[0089] In different playing methods, the number of mahjong tiles stored in the card storage channel and the length of the card dealing sequence are quite different. In order to enable the sub-channel 71e to quickly connect to the card dealing sequence regardless of the playing method, such as Figure 6 As shown, in this embodiment, the branch channel 71e has an extension section 71f extending from the connection point with the outer channel toward the card inlet 71a; alternatively, a patch 73 can be installed in the branch channel 71e, and the patch 73 has a supporting ridge 73a protruding from the branch channel 71e toward the main channel 71d and extending toward the card inlet 71a.

[0090] The extension section 71f and the supporting convex eave 73a have the same function and can be provided separately or simultaneously. When both are provided simultaneously, the extension section 71f can play the role of supporting the convex eave 73a. In this case, the lengths of the two sections can be set to be different, so that different sequence lengths can be used in different playing methods.

[0091] from Figure 5 and Figure 6 As can be seen, in this embodiment, the extension section 71f or the supporting convex ridge 73a is located on the inner sidewall of the main channel 71d and is smaller than the width of the main channel 71d. Furthermore, the width of the extension section 71f or the supporting convex ridge 73a gradually narrows from the end facing the branch channel 71e to the end facing the card inlet 71a. This is to prevent the extension section 71f or the supporting convex ridge 73a from obstructing the advancement of the card loading pusher 82 when a single card loading pusher 82 is used to push cards. Obviously, when separate card loading pushers 82 are used to push the card dealing sequence and the card drawing sequence, the above-mentioned width requirement for the extension section 71f or the supporting convex ridge 73a is no longer required.

[0092] The working principle of the double-up mode mahjong machine of the utility model is:

[0093] In the eight-hole machine mode, three or four layers of mahjong tiles are deposited one by one from the tile inlet 71a into the storage channel. As the tile piles are deposited, on the one hand, under the guidance of the guide surface 72b, the mahjong tiles in the top layer or two layers gradually turn their forward direction to the first tile outlet 71b. On the other hand, the mahjong tiles in the top layer or two layers exert pressure on the probe 55, eventually prompting the push rod 53 to release the support of the first tile lifting plate 1, so that the first tile lifting plate 1 can be lifted and lowered synchronously with the second tile lifting plate 2 to receive the tiles.

[0094] In the four-slot machine mode, the double-layer card piles are stored one by one from the card inlet 71a into the card storage channel. These card piles always move along the main channel 71d, so they will not squeeze the probe 55, and the top rod 53 will maintain a lifting posture for the first card raising board 1. At this time, all the card piles will be sent to the table from the second card outlet 71c and the second card raising board 2.
