Technical Field

[0001] The utility model relates to the technical field of automatic mahjong machines, in particular to a standing upright prompting mechanism for automatic mahjong machines and the automatic mahjong machine. Background Art

[0002] Riichi is a mahjong term, which means to hold down a card and report a winning hand when there are no cards to be won, such as a pick, a touch or a kang. When you are waiting for a winning hand, you have touched all the cards yourself. Riichi can increase the number of points. The Riichi reminder of existing automatic mahjong machines is usually achieved through a special Riichi stick.

[0003] For example, in the Chinese patent literature, a mahjong table with publication number CN1111540A disclosed on November 15, 1995, has a display device in the center of the top of the mahjong table, and a touch switch is provided on the display device. Various information necessary for playing the game is displayed on the display device, and various information necessary for playing the game is input through the touch switch provided on the display device. The application mentions that the prior art of standing broadcast is realized by placing a standing rod on the standing operation part, and a standing sound is emitted when the standing rod is placed on the standing operation part.

[0004] The shortcomings of the existing technology are: 1. The upright rod needs to be specially manufactured, and there is a possibility of loss during the use of the electric card sorting machine, and it is not easy to store; 2. The upright rod needs to be placed on the upright operating part to get a prompt. When the upright rod is in an unbalanced position, it is difficult to get an accurate prompt, which affects the user experience of the electric card sorting machine; 3. The upright operating part is arranged in the dice control part that can be raised and lowered relative to the mahjong table. If the existing upright rod is not removed from the operating part, if the dice control part is raised and lowered, the upright rod will move, and even the upright rod will get stuck in the column and the dice control part will be raised and lowered, posing a safety hazard.

[0031] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0032] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] Figures 1 to 8 As shown, one embodiment of the utility model proposes a standing upright prompting mechanism for an automatic mahjong machine, comprising a dice plate 1, chips 2 and a prompting component. A standing upright induction area is formed by setting a first induction coil on the dice plate 1, and a second induction coil 21 is provided in the chips 2, so that magnetic induction is generated when the chips 2 approach or contact the standing upright induction area 11, and the prompting component responds to the magnetic induction to perform a standing upright prompt.

[0034] The dice plate 1 and the chips 2 are mechanisms already present in the existing automatic mahjong machines, and the middle position on the upper side of the dice plate 1 is the dice throwing area 10. The present application forms the upright induction area 11 by setting a first induction coil on the dice plate 1, and sets a second induction coil 21 in the chips 2 to cooperate with the upright induction area 11, so that the dice plate 1 and the chips 2 have a non-contact magnetic induction function, and the chips 2 only need to pass through the upright induction area 11 from above to obtain the induction signal so as to give the upright prompt through the prompt component, thereby reducing the placement accuracy required for the chips 2 and improving the reliability of the upright prompt. When the upright prompt is given, it is necessary to obtain the voltage change signal of the chips 2. In this embodiment, the upright prompt is given by using the magnetic induction signal generated when the chips 2 move to the upright induction area 11. When the chips 2 are located in the upright induction area 11 and do not move, the upright prompt will not be repeated. After the first announcement, even when the next game starts, Riichi will be announced only when the chip 2 is removed and moved again to pass through the Riichi sensing area 11, thereby ensuring the reliability of the Riichi prompt.

[0035] Compared with the special upright stick required by the prior art, the present application designs the chip 2 to have an upright reminder function, which does not require a special upright stick and is easy to use. In addition, the chip 2 is not easy to be lost compared to a single upright stick and is convenient to store.

[0036] The prompt component is used to prompt standing at attention, including but not limited to voice broadcast, light indication, flashing light reminder, screen text display, etc.

[0037] The upper end surface of the dice plate 1 is a plane, and the upper end surface of the dice plate 1 opposite to the upright sensing area 11 is a plane, convex, concave, groove or other special-shaped structure. When the upright sensing area 11 is a plane, it is necessary to set a marker such as a prompt color or a border line to serve as a prompt. The chips 2 are used to match the lower side of the upright sensing area 11 and correspond to the structure of the upright sensing area 11. For example, when the upright sensing area 11 is a plane, the lower side of the chips 2 is also a plane, or when the upright sensing area 11 is a concave surface, the lower side of the chips 2 is a convex surface, so as to achieve reliable matching between the upright sensing area 11 and the chips 2.

[0038] One embodiment of the utility model provides a standing upright prompting mechanism for an automatic mahjong machine, wherein the prompting component is a voice broadcasting component. The voice broadcasting component is a broadcasting speaker, in which the words "standing upright" are pre-recorded, and the voice broadcasting component is arranged in the automatic mahjong machine. In this embodiment, Figure 3 As shown, a radio frequency chip 26 is provided inside the chip 2, which can emit a radio frequency signal to the outside. When the magnetic steel coil and the upright induction area 11 generate a magnetic induction signal, the radio frequency signal can be sent to the prompt component.

[0039] As a simple replacement for the above solution, the voice broadcast component is arranged in the chips 2 or the dice tray 1.

[0040] To improve the convenience of the riichi prompt for each player's operation, several riichi sensing areas 11 are provided in a circumferential array around the longitudinal axis of the dice tray 1. Exemplarily, as Figure 1 shown, the dice tray 1 is provided with riichi sensing areas 11 corresponding to four dealer positions respectively. The four riichi sensing areas 11 are arranged in a rectangular array on the dice tray 1. Since the chips 2 are in a long strip structure, the riichi sensing areas 11 inside the dice tray 1 are also slender in shape to correspond to the chips 2. In this example, the top view shape of the dice tray 1 is a rounded square, and the length direction of the riichi sensing areas 11 is arranged along the edge of the dice tray 1. During four-player mahjong, the riichi can be prompted through the riichi sensing areas 11 at the positions where the four players are located. As Figure 2 shown, the areas enclosed by the dotted lines at both ends of the chip 2 are respectively a second induction coil 21. When the chip 2 is placed in the riichi sensing area 11, the second induction coils 21 at both ends of the chip 2 respectively correspond to the first induction coils, and the movement of the chip 2 will generate an induction signal, ensuring a reliable induction effect between the chip 2 and the riichi sensing area 11.

[0041] As a simple replacement for the above example, two or three riichi sensing areas 11 are provided, which can adapt to the application of two-player mahjong or three-player mahjong.

[0042] A riichi prompt mechanism for an automatic mahjong machine proposed in one embodiment of the present utility model, as Figure 8 shown, the optoelectronic component is a prompting lamp 3 on one side of the riichi sensing area 11. During riichi, after the chip 2 passes by the corresponding riichi sensing area 11, the prompting lamp 3 lights up or flashes.

[0043] As a simple replacement for the above solution, the optoelectronic component is a display screen, and the riichi字样 is directly displayed on the display screen.

[0044] Furthermore, the prompting component is a combination of the above voice broadcast component and optoelectronic component, having a dual broadcast prompt form.

[0045] As a riichi prompt mechanism for an automatic mahjong machine proposed in one embodiment of the present utility model, the first induction coil is an annular induction coil 12. As Figure 4 shown, there is one first induction coil, and the axis of the first induction coil is perpendicular to the upper end surface of the dice tray 1. The space with a certain magnetic field intensity upward on the upper side of the riichi sensing area 11 is the induction range for riichi. The single annular induction coil is arranged corresponding to the inner side of the edge of the riichi sensing area 11, so that the induction magnetic field of the annular induction coil 12 has a larger distribution range in the riichi sensing area 11, facilitating the cooperation with the second induction coil 21 on the chip 2.

[0046] As a simple replacement for the above solution, a plurality of annular induction coils are arranged in the upright induction area 11 , thereby forming multi-point distributed induction coils to increase the magnetic field density of the upright induction area 11 , facilitating the induction of the second induction coil 21 in the chip 2 .

[0047] As one of the embodiments of the present invention, a vertical prompt mechanism for an automatic mahjong machine is proposed. The chips 2 include a long strip-shaped housing with a cavity and a winding bracket 25 arranged in the cavity. The second induction coil 21 is arranged at the end of the winding bracket 25. The winding bracket 25 is provided with a radio frequency chip 26 whose circuit is connected to the second induction coil 21. The radio frequency chip 26 emits a signal when the second induction coil 21 generates an induced current. Figure 3 As shown, the chip 2 includes a first shell 22 and a second shell 23 in a strip shape, and the first shell 22 and the second shell 23 are both provided with a groove 24. The first shell 22 and the second shell 23 are assembled to form a cavity, and the first shell 22 and the second shell 23 are fixed by bonding, pressing, etc. A winding bracket 25 is fixed inside the cavity along its length direction, and the second induction coil 21 is wound on both ends of the winding bracket 25. The axis of the second induction coil 21 corresponds to the length direction of the winding bracket 25. When the chip 2 passes through the upper side of the upright induction area 11, it can obtain an induced current through magnetic induction, and the induction signal is emitted outward through the radio frequency chip 26 to control the prompt component to perform an upright prompt. The chip 2 has two spaced sensing positions and many sensing points, which facilitates the induction coordination between the chip 2 and the upright induction area 11.

[0048] As one of the embodiments of the present invention, a vertical reminder mechanism for an automatic mahjong machine is provided, a reminder area is provided on the upper side of the dice plate, and the vertical sensing area is provided in the reminder area, the reminder area protrudes to the outside of the dice plate; or the reminder area is concave to the inside of the dice plate; or a marker is provided in the reminder area. For example, Figure 2 and Figure 5 As shown, the dice plate 13 is provided with a concave positioning groove, the upright sensing area is set in the positioning groove, and the chips are placed horizontally in the positioning groove. The upright sensing area 11 is set concavely on the dice plate 1 to form a positioning groove 13 that can position the chips 2. The positioning groove 13 intuitively displays the position of the upright sensing area 11, which is convenient for players to place or pass through the upright sensing area 11, and convenient for positioning the chips 2 on the dice plate 1.

[0049] The positioning groove 13 includes a groove bottom surface 14 and a groove side surface surrounding the groove bottom surface 14. The upper side of the positioning groove 13 is open, and the groove bottom surface 14 cooperates with the chip 2. When the chip 2 is placed in the positioning groove 13, the groove side surface is provided with at least one interval relative to the outer side of the chip 2 to facilitate the removal of the chip 2. Figure 5As shown, the chip 2 is in the shape of an elongated strip, the groove bottom surface 14 of the positioning groove 13 is in the same shape as the bottom surface of the chip 2 to form a fit, and the contact surface between the groove bottom surface 14 and the chip 2 is a plane. The chip 2 has four side surfaces, and the groove side surfaces of the positioning groove 13 are also provided with four. Through the fit between the groove bottom surface 14 and the chip 2, the chip 2 has high stability after being placed in the positioning groove 13.

[0050] As a simple replacement for the above solution, Figure 7 As shown, the contact surface between the groove bottom surface 14 and the chips 2 is a downwardly convex curved surface.

[0051] As one of the embodiments of the present invention, a vertical prompting mechanism for an automatic mahjong machine is provided. Figure 5 and Figure 6 As shown, the side surface of the slot includes a first side surface 15 corresponding to the end of the chip 2 in the length direction. The first side surface 15 is arranged outwardly from the slot bottom surface 14 to the opening relative to the upper side surface of the dice plate 1, and a gap is formed between the first side surface 15 and the chip 2. The gap is set between the first side surface 15 and the chip 2 to form a space for human hands to enter, so that the chip 2 can be easily taken out of the positioning slot 13.

[0052] Furthermore, the groove side includes a second side surface 16 corresponding to the end of the chip 2 in the width direction, and the second side surface 16 smoothly transitions with the groove bottom surface 14 and the second side surface 16 is arranged to be inclined outward from the groove bottom surface 14 to the opening relative to the upper side surface of the dice plate 1. When the chip 2 is placed in the positioning groove 13, it can be guided into the positioning groove 13 by the second side surface 16, thereby improving the reliability of the chip 2 being in place. When the chip 2 is taken out, the chip 2 can be pushed out along the second side surface 16 by pressing the chip 2 from the gap, thereby further facilitating the removal of the chip 2.

[0053] An automatic mahjong machine proposed as one of the embodiments of the utility model includes a mahjong machine body, and the mahjong machine body is provided with the above-mentioned upright prompting mechanism.

[0054] like Figure 8 As shown, the dice tray is provided with several function keys between adjacent prompt lights 3, and the four prompt lights 3 can light up in turn as a ticker. The function keys include a first function key 4, a second function key 5, a third function key 6 and a fourth function key 7. The second function key 5 and the fourth function key 7 are respectively located at the diagonal corners of the dice tray as start keys. The first function key 4 is an automatic operation key, and the third function key 6 is a manual operation key.

[0055] The voice broadcast component disclosed in the present application can broadcast not only Riichi but also the banker's position. The banker's position broadcast includes four segments of voice, and the broadcast timing of the four segments of voice is:

[0056] 1. Game start: After the marquee finishes spinning, the first dealer in the east wind circle is announced;

[0057] 2. The East Wind Circle ends and the South Wind Circle begins: After the East Wind Circle ends, the announcement is made when the first dealer of the South Wind Circle is determined; only when the East Wind Circle is finished and the South Wind Circle is entered will there be a voice message of "The East Wind Circle ends". If the South Wind Circle is finished and the South Wind Circle is entered, there will be no voice message of "The East Wind Circle ends", only two voice messages of "The last round" and "The game continues";

[0058] 3. The last round: After the "East", "South" and "West" of the South Wind Circle have finished being the dealer, the fourth "North" dealer is determined. The "Game Continue" voice of the last round of the South Wind Circle will continue to play without being interrupted if the dice are hit multiple times in a row during the voice broadcast. If the dice are hit multiple times during the voice broadcast, the dice hit during the broadcast will not trigger the voice. Only the dice hit after the broadcast can trigger the voice.

[0059] 4. Game continues: The "North" dealer in the South Wind Circle will make a report after winning consecutive games.

[0060] The four indicator lights 3 are used as a marquee to realize three states:

[0061] A. Press the first function key 4 and then the third function key 6 to enter the Dongfeng Circle Marquee. If no one plays the dice, the dealer will be randomly selected after two seconds of rotation.

[0062] B. Press the third function key 6 and then the first function key 4 to enter the Dongfeng circle marquee. If no one plays the dice, the marquee will go out after ten seconds of rotation. The dealer will not be randomly determined and the speed of the marquee will remain unchanged.

[0063] C. No matter which button you press first, you will directly enter the South Wind Circle Marquee. If no one rolls the dice, the marquee will go out after spinning for ten seconds. The dealer will not be randomly determined and the speed of the marquee will remain unchanged.

[0064] There are several special application scenarios for the marquee and voice broadcast: 1. If the dealer is not determined after the marquee has been running for ten seconds, only the dice light will light up when playing dice, and the light of the east / south wind circle will not light up, which is equivalent to the play method of ordinary machines and will not trigger voice;

[0065] 2. If the dealer is not determined after the marquee has been spinning for ten seconds, you do not need to roll the dice first and can press the first function key 4 to trigger the marquee;

[0066] 3. After the marquee rotates for two seconds, the dealer is randomly determined and the dice key is locked. However, the marquee can still be operated by pressing the first function key 4;

[0067] 4. Within ten seconds of the ticker, you can press the first function key 4 again to switch to triggering a two-second ticker. The most recently triggered first function key 4 operation will overwrite the previous one.

[0068] 5. When you directly enter the south wind circle, the first time you press the dealer dice key, the voice will not be triggered (the announcement of "the east wind circle ends and the south wind circle begins" is only made when you enter the south wind circle from the end of the east wind circle. This announcement will not be made when you start the south wind circle);

[0069] 6. When the east wind circle ends, after pressing the up / down key and then quickly pressing the dice key of the south wind, the voice broadcast of "the east wind circle ends" will be broadcast. The operation sound prompt will not affect the voice broadcast, and the voice priority is higher than the operation prompt sound;

[0070] 7. If chip 2 is not taken down after triggering the Riichi voice in the previous round, the voice will not be triggered directly after the start of the second round. The voice can only be triggered after the chip is taken down and put back.

[0071] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
