Description

Technical Field

[0001] The invention belongs to the technical field of mahjong machines, and in particular relates to a double-upgrading-card-mode mahjong machine and a card-upgrading mechanism thereof. Background Art

[0002] According to the number of card-raising ports, the current fully automatic mahjong machines can be divided into four-port mahjong machines and double-port mahjong machines. As the name implies, each side of the four-port mahjong machine is only equipped with one card-raising port, while each side of the double-port mahjong machine has two card-raising ports.

[0003] In a four-slot mahjong machine, after the mahjong tiles are raised to the table, the player needs to grab some tiles in turn; in a double-slot mahjong machine, the tiles that are put on the table from the lifting port close to the player are the dealing sequence, and the tiles that are put on the table from the lifting port close to the center of the mahjong machine are the drawing sequence. In this way, the player does not need to manually grab the tiles at the beginning of the game, and can directly take the dealing sequence to start the game.

[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's gameplay. Summary of the invention

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

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

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

[0008] A first card raising board, the first card 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-port machine working positions which are lifted and lowered synchronously with the second card-lifting plate, and four-port machine working positions which are kept in a horizontal state.

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

[0012] The first card raising board and the second card raising board can be driven by different card raising drive components to work, and the card raising drive component of the first card raising board can be controlled separately according to the need of playing cards. However, in order to save power, only one card raising drive component is used in the present invention.

[0013] At this time, as a preferred embodiment, the card-raising mechanism further includes:

[0014] A card-lifting driving component, wherein the second card-lifting plate is driven to rise and fall by the card-lifting driving component;

[0015] A linkage component, which 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] A 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, and technicians in this field 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] On the basis of the linkage components, those skilled in the art can develop various card-raising mode switching components 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 component 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; obviously, it is 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 through a top rod erected on the swing arm;

[0023] The swing arm comprises a hinge point and a long arm end and a short arm end on both sides of the hinge point, the top rod is arranged at the long arm end, and the short arm end is connected to the driving unit; or the driving unit is arranged 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 swing arm is close to the first card-raising board, the swing arm can support the first card-raising board from the bottom; when there is a large height difference between the swing arm and the first card-raising board, it is necessary to erect a top rod on the swing arm to support the first card-raising board.

[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 between the top rod or the swing arm and the first card-raising plate to be 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 arranged at the hinge point, or a linear drive arranged at the end of the short arm.

[0028] A driving unit provided by the present invention comprises 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-mouth machine working position; otherwise, the swing arm remains at the four-mouth 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, which makes the swing arm have a tendency to move toward the bottom of the first card raising board. The sensing module is a probe extending into the card storage channel. In the working position of the eight-mouth machine, the probe is squeezed by the card dealing sequence, so that the lever applies 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, the lever is connected to the linear drive, the infrared detector or the magnetic sensor and the linear drive are both connected to a control element, and the control element is used to control the operation of the linear drive according to the output signal of the infrared detector or the 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 for facilitating 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 card 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, the push rod will return to the starting point from the bottom of the lifting board after pushing the mahjong tiles onto the lifting board, and the push rod under the first lifting board is on the running path of the push rod. Therefore, in the above-mentioned lifting mechanism, the push rod is hinged with the swing arm, and the push rod has a supporting position where it stands upright on the swing arm and supports the first lifting board, and a avoiding position where it rotates relative to the swing arm to avoid the mahjong machine actuator (including the above-mentioned push rod) passing under the first lifting board;

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

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

[0038] The push rod in 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 support position to the avoidance position. After the card-loading push rod passes, the push rod will automatically return to the support position under the action of the second elastic structure.

[0040] It can be expected that when the card dealing sequence is sent to the first card raising board, the swing arm and the top rod are also in the four-mouth machine working position, that is, the swing arm and the top rod are normally supporting the first card raising board. Setting the force application position of the top rod or the swing arm to the free end of the first card raising board is conducive to disconnecting the linkage relationship between the first card raising board and the second card raising board with a relatively small force, and 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).

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

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

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

[0044] A card distributor, on which a guide surface is formed for guiding the card dealing sequence into the branch channel, the guide surface extends from the outer side wall of the main channel across the main channel and along the outer side 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 card-raising mechanism, the card storage mechanism in the mahjong machine of the present invention also has two working modes: in the eight-mouth machine working mode, the first card outlet is used to deliver the card-dealing sequence (composed of the top one or two layers of mahjong tiles of all the card piles stored in the main channel) to the first card-raising board, and the second card outlet is used to deliver the card-drawing sequence (composed of the bottom two layers of mahjong tiles of all the card piles stored in the main channel (71d)) to the second card-raising board. In the four-mouth machine working mode, the first card outlet is not enabled, and all mahjong tiles are stored in the main channel (the height of the card pile is reduced), and only the second card outlet is used to deliver tiles to the second card-raising board; at this time, all mahjong tiles can be delivered to the second card-raising board at one time, and the player can grab the card-dealing sequence by himself; or the mahjong tiles can be delivered in batches, that is, several card piles arranged in front of the queue are first delivered to the table as the card-raising sequence, and after the player takes away the card-dealing sequence, the remaining card piles are delivered to the table as the card-drawing sequence.

[0047] It can be seen that the reason why the above two working modes are compatible is that the present invention sets the main channel at a low position and the branch channel at a high position, so that the card dealing sequence can be selectively sent 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 working position of the eight-hole machine, the first card-raising board and the second card-raising board are raised and lowered together, wherein the first card-raising board is used to deliver the card-dealing sequence to the tabletop, and the second card-raising board is used to deliver the card-drawing sequence to the tabletop; on the working position of the four-hole machine, the first card-raising board is kept in a horizontal state flush with the tabletop, and all mahjong tiles are delivered to the tabletop 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 present invention utilizes 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, thereby being able to control the working state of the first card raising board very simply and sensitively.

[0051] (3) The present invention sets the force-applying position of the push rod or the swing arm as 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 invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] Example 1

[0061] like Figure 1 and Figure 2 As shown, the card-raising mechanism of a double-card-raising mode mahjong machine in this embodiment includes a first card-raising board 1 and a second card-raising board 2. The first card-raising board 1 and the second card-raising board 2 are both hinged to the frame 9 and are roller coaster-type slope card-raising 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 by their respective card-raising drive components 3; similarly, the first card-raising board 1 and the second card-raising board 2 on the four sides of the mahjong machine can be driven by the same card-raising drive unit, or by their respective 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 sync, 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 with 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 at the four sides of the mahjong machine has been described in the patent owner'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-raising plate 1, and a metal member 42 disposed at the bottom of the second card-raising plate 2; the metal member 42 is attracted by the magnetic member 41, which causes the first card-raising plate 1 and the second card-raising plate 2 to be connected, forming a linkage relationship. Obviously, the effect of exchanging the positions of the metal member 42 and the magnetic member 41, or replacing the metal member 42 with another magnetic member 41, is the same.

[0066] Obviously, the linkage relationship between the first card-raising board 1 and the second card-raising board 2 produced by the linkage component 4 is not very strong. When the second card-raising board 2 descends and the first card-raising board 1 remains flush with the desktop, the linkage relationship between the two is disconnected. This makes the first card-raising board 1 have two working states: eight-port machine working position and four-port machine working position.

[0067] On the working position of the eight-mouth machine, the first card raising board 1 and the second card raising board 2 are lifted and lowered 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 working position of the four-mouth machine, 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 playing needs of multiple audiences can be met in one mahjong machine at the same time.

[0068] like Figure 3 As shown, this embodiment adopts a card-raising mode switching component 5 to change the working state of the first card-raising board 1. The card-raising mode switching component 5 includes a swing arm 51, and the swing arm 51 includes a hinge point 51a movably connected to a base 52 or other parts 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; at this time, the drive unit (at this time, 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, and at this time, 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 to the bottom of 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 lever 54 which is slidably mounted on a base 52 . One end of the lever 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 lower side of the first card raising plate 1, and 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: cards have not been deposited, or cards have been deposited but have been sent to the first card raising board 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 board 1.

[0073] like Figure 3 As shown, in this embodiment, the side of the probe 55 facing the card storage channel is an arc surface 55a for the card dealing sequence to pass over. The arc surface 55a not only does not hinder the progress of the card dealing sequence, but also its larger span enables it to contact with more mahjong tiles, so that the lever 54 can receive the squeezing force from multiple mahjong tiles, and it is 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 is rotatable 360°, 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 under the first card-lifting plate 1 is 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 (such as a hinge) in this embodiment, and the push rod 53 has a supporting position erected on the swing arm 51 to support the first card-lifting plate 1, and a avoiding position rotating relative to the swing arm 51 to avoid the card-loading push rod 81; and a second elastic structure (such as a torsion spring) is provided between the push rod 53 and the swing arm 51 to make the push rod 53 have a tendency to move toward the supporting position.

[0075] When the card loading push rod 81 moves to the position of the push rod 53, the push rod 53 will be pressed from the wedge surface 53a to make the push rod 53 turn from the supporting position to the avoiding position. After the card loading push rod 81 passes, the push rod 53 will automatically return 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 can be expected that when the card dealing sequence is sent to the first card raising board 1, the swing arm 51 and the top rod 53 are also in the four-port machine working position, that is, the swing arm 51 and the top rod 53 are normally supporting the first card raising board 1. In this embodiment, the force application position of the top 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 the minimum force, and 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 desktop).

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

[0078] 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 apply a reaction force to the probe 55 when crossing the arc surface 55a. The reaction force is sufficient to overcome the elastic tendency of the first elastic structure, causing the lever 54 to slip, thereby causing the swing arm 51 to swing, and the long arm end 51b moves from the bottom of the first card raising board 1 to the lower side of the first card raising board 1; at this time, the card raising drive unit is started, driving the second card raising board 2 to descend, and under the action of the linkage component 4, the first card raising board 1 also descends accordingly, and the card dealing sequence and the card drawing sequence are then respectively raised from the first card raising board 1 and the second card raising board 2 to the table top, which is the eight-mouth machine mode;

[0079] When the card-loading push rod 81 completes the card-loading action and intends 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, so that the push rod 53 turns over 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 card dealing sequence at a height equivalent to that of the probe 55 stored in the card storage channel, the swing arm 51 is driven by the first elastic structure to remain below the first card raising board 1, and the top rod 53 lifts the first card raising board 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 board 2 to descend, due to the lifting of the top rod 53, the connection between the magnetic part 41 and the metal part 42 is disconnected, and all the mahjong cards in the card storage channel will be lifted from the second card raising board 2 to the table top. This is the four-port machine mode.

[0081] Example 2

[0082] like Figure 4 As shown, the present embodiment is a double-up 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 and pushing mechanism 6, a card storage mechanism 7, a card loading mechanism 8 and a card raising mechanism. The stacking and pushing mechanism 6 is used to stack the card piles and store the card piles one by one in the card storage mechanism 7, the card storage mechanism 7 is used to store the card piles, the card loading mechanism 8 is used to send the card piles to the card outlet, and the card raising mechanism is used to send the mahjong tiles to the table, and the card raising mechanism is the same as that in embodiment 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. The 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. The first card outlet 71b is connected to the card inlet 71a by connecting to the main channel 71d. The branch channel 71e connects the main channel 71d and the first card outlet 71b and is only used for conveying 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 cards stored in the main channel 71d are all three-layer or four-layer piles. Among these piles, the mahjong cards in the lower two layers are always in the main channel 71d, that is, they constitute a card drawing sequence, and the mahjong cards in the top layer or two layers will enter the branch channel 71e downstream to constitute a card dealing sequence; the probe 55 extends 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, and the outer side 72a of the card distributor 72 is detachably connected to the card storage 71, so that it and the card storage 71 provide an outer side wall for the main channel 71d; the inner side of the card distributor 72 is formed with a guiding surface 72b, the starting end of which 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 guiding surface 72b and is led by the guiding 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 piles of cards 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 of cards can be raised to the table at once, which is the traditional four-slot machine gameplay; or the piles of cards at the front of the queue can be used as the dealing sequence, and the remaining piles can be used as the drawing sequence and 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, the length of the card dealing sequence, etc., 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 convex eave 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 eaves 73a have the same function and can be set separately or simultaneously. When the two are set simultaneously, the extension section 71f can play the role of supporting the convex eaves 73a. At this time, the lengths of the two can be set to be different, so that different sequence lengths can play a role in different playing methods.

[0091] from Figure 5 and Figure 6 It can be seen that in this embodiment, the extension section 71f or the supporting convex eaves 73a are both located on the inner side wall of the main channel 71d, and their width is smaller than the width of the main channel 71d; and the width of the extension section 71f or the supporting convex eaves 73a gradually narrows from one end facing the branch channel 71e to one end facing the card inlet 71a. This is to avoid the extension section 71f or the supporting convex eaves 73a hindering the card pusher 82 from advancing when a card pusher 82 is used to push cards. Obviously, when an independent card pusher 82 is used to push the card dealing sequence and the card drawing sequence respectively, there is no above requirement for the width of the extension section 71f or the supporting convex eaves 73a.

[0092] The working principle of a double-up mode mahjong machine of the present invention is:

[0093] In the eight-mouth machine mode, three or four layers of mahjong tiles are deposited one by one from the card inlet 71a into the card storage channel. As the mahjong tiles are deposited, on the one hand, under the guidance of the guide surface 72b, the advancing direction of the mahjong tiles on the top layer or two layers gradually turns to the first card outlet 71b. On the other hand, the mahjong tiles on the top layer or two layers will apply pressure to the probe 55, and finally the push rod 53 releases the support of the first card raising plate 1, so that the first card raising plate 1 can be raised and lowered synchronously with the second card raising plate 2 to receive the tiles.

[0094] In the four-mouth machine mode, 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 push 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.
