BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic mahjong machine. More specifically, the present invention relates to an automatic mahjong machine in which a transport path for distributing tiles on a turntable to respective tile stacking and supplying devices is provided for each tile stacking and supplying device. Mahjong related.

[0002]

2. Description of the Related Art Conventionally, an automatic mahjong machine has been known. The automatic mahjong machine has a turntable that stirs a large number of tiles inserted from the tile slot inside the table body with a tile slot opened on the top plate, and four corners surrounding the turntable. And a transport path for distributing tiles on the turntable to the tile stacking supply devices at each corner. Then, tiles supplied by the transport path are lined up in a tile stacking supply device at each corner.
The tiles are stacked two by two, and the stacked tiles are lifted on the upper surface of the desk body.

By the way, in a conventional automatic mahjong machine,
Since the tiles are distributed to the tile stacking and supplying device in each corner by one transport path, there is a disadvantage that it takes a considerable time until the distribution is completed. Therefore, in recent years, an automatic mahjong machine provided with a plurality of transport paths, specifically, four corners has been provided.

In such an automatic mahjong machine, when it is detected that a certain number of tiles have been supplied to the tile stacking and supplying device in the corner to be contacted, gates for interrupting the supply of tiles by the transport paths are provided for the respective transport paths. The tiles on the transport path at the corner where distribution has been completed are returned to the turntable.

[0005]

However, according to the conventional automatic mahjong machine provided with a plurality of transport paths, tiles sent on the transport path are dropped on the turntable by the gate, but the tiles are dirty. When it is wet, the tiles are placed on the turntable as if they were tightly attached, and the tile drop-off member (metal) attached to the fixed support provided at the rotation center of the turntable The turntable is hit by the rotation of the turntable and is thrown out of the turntable. However, since the same state is repeated on the turntable again, the tile is not sent to the transport path where the tile is open, and the tiles are aligned. Is not completed. It is also conceivable to reduce the time for which the tiles are on the turntable by attaching a plurality of the above-mentioned tile removing members, but if a plurality of the tile removing members are provided, a large number of the tiles will ride on the turntable. At a certain stage, the tile drop-off member is rather obstructive, and impedes the feeding into the transport path.

The present invention has been made in view of the above-mentioned conventional circumstances, and a purpose thereof is to provide an automatic mahjong machine having a plurality of transport paths, in which the tiles become dirty or wet. Even so, it is possible to ensure that the time until the distribution of tiles to each corner is completed can be shortened by reliably swinging off the turntable.

[0007]

In order to achieve the above object, the automatic mahjong machine of the present invention comprises a turntable for stirring a large number of tiles inserted from a tile slot, and four turntables surrounding the turntable. It has tile stacking and supplying devices arranged in each corner, and four transport paths for distributing tiles on the turntable to the tile stacking and supplying device in each corner. When a certain number of tiles are supplied to the device, an automatic mahjong machine provided with a gate for shutting off the supply of tiles by the transport path is provided with a turntable outside the support of a dice stand fixed at the rotation center of the turntable. A rotating frame that rotates in a direction opposite to the rotation direction of the turntable is mounted, and a tile drop-off member having a length reaching near the outer peripheral edge of the turntable is mounted on the rotating frame.

[0008] rotation of the rotary frame, Ru Oh <br/> in a way to rotate through utilizing the rotation of the turntable gear mechanism. Also, the number of tile drop-off members attached to the rotating frame may be one or more, but when a plurality is used, two or three tiles which do not hinder the stirring and feeding of tiles are effective. . Furthermore, the above-mentioned tile drop-off member is made of a metal wire or a resin wire formed in a coil spring shape, or a resin rod or the like. Anything that can be shaken off is good.

[0009]

According to the above arrangement, the number of tiles on the turntable decreases as the distribution proceeds, and even if the tiles stick to the surface of the turntable due to dirt or moisture, the tiles remain on the turntable. Is hit off the tile swing-out member attached to the rotating frame rotating in the direction opposite to the direction of rotation of the tile, and is shaken out of the turntable. Since the turntable and the rotating frame rotate relatively in the opposite direction in the swing-down, the time required for the tiles on the turntable to be shaken off is reduced.

FIG. 1 shows an embodiment of the automatic mahjong machine of the present invention.
Referring to FIG. 3, FIG. 1 is a perspective view of a main part of the automatic mahjong machine according to the present invention, with a top plate removed, in which 1 is a console body, 2 is a turntable, and 3 is a tile stacking supply. Device, 4
Denotes a transport path, and 5 denotes a tile.

The table body 1 is formed in the shape of a flat rectangular box having an open upper surface. A dice table 6 is supported at the center of the table body, and a turntable 2 is centered on a column 7 supporting the dice table 6. It is rotatably supported. Furthermore,
At the four corners surrounding the turntable 2, tile stacking and supplying devices 3 are respectively arranged, and the tile stacking and supplying device 3 at each corner and the turntable 2 are connected with each other via the transport path 4.

The table body 1 is covered with a top plate 8 so as to be openable and closable by a top plate 8, and a substantially square window hole 9 into which a dice stand 6 is fitted is opened in the center of the top plate 8, and the window hole is provided. A tile slot 10 is provided between the edge of the hole 9 and the periphery of the dice table 6, and the tile slot 10 is openable and closable by a door 11. The turntable 2 is located immediately below the tile slot 10. Is located.

The turntable 2 is formed in the shape of a truncated cone as shown in the figure, and is rotated by the operation of a motor (not shown) provided on the inner bottom of the table body 1, and is inserted from the tile slot. A large number of tiles 5 are agitated. The start and stop of the operation of the motor are electrically controlled by a control unit (not shown).

On the upper horizontal surface of the turntable 2, a ring-shaped straight bevel gear 12 is fixed with screws 13 with the tooth surface facing upward, and a straight bevel gear 14 meshing with the straight bevel gear 12 is provided. It is attached to a shaft 15 attached to the outer peripheral surface of a column 7 fixed to the center of the turntable 2 so as to freely rotate. A rotary frame 16 is rotatably fitted to the outside of the support column 7 via a collar 21, and a straight bevel gear 17 meshing with the straight bevel gear 14 is provided on the inner surface of the rotary frame 16. It is fixed with a screw facing downward.

The outer upper surface of the rotating frame 16 has a cross section substantially L
A mounting piece 18 bent in a letter shape is fixed to an opposing position on a diameter line passing through the center of the column 7 with a screw 20, and a tile swing-down member 19 is connected and fixed to an upright portion of the mounting piece 18. The tile swing-down member 19 is formed by winding a metal wire in the form of a coil spring, and has a length such that its tip reaches the vicinity of the outer peripheral edge of the turntable 2 while being connected to the mounting piece 18. A weight 22 is attached to the tip of the tile swing-down member 19 so that the tile swing-down member 19 is always kept on the upper surface of the turntable 2. Thus, when the door 11 is opened and the tile 5 is inserted from the tile insertion slot 10, the tile 5 enters the lower side of the tile swing-off member 19, thereby preventing the tile swing-down member 19 from being pushed upward and stabilizing. That is, the tile swing-down operation is performed.

With the above configuration, the tiles 5 dropped onto the turntable 2 in the table body 1 from the tile slot 10 of the tabletop 8 immediately rotate the turntable 2 and the turntable 2 rotate. The bevel gear 12, the bevel gear 14, and the bevel gear 17 contact the tile drop-off member 19 attached to the rotating frame 16 attached to the rotating frame 16 that rotates in the direction opposite to the rotation direction of the turntable 2 via the bevel gear 17. The tiles 5 are agitated and pushed out of the turntable 2, sent into the transport path 4, and supplied to the tile stacking and supplying device 3 to align the tiles 5. When the above operation proceeds and each of the four corners reaches a predetermined number, the gate provided on the transport path 4 at that corner closes so that the tiles 5 cannot be sent in. However, the remaining tiles 5 become dirty. It may be stuck to the surface of the turntable 2 due to moisture or moisture.

When the above occurs, the turntable 2 and the rotating frame 16 to which the tile swing-off member 19 is attached are mounted.
Is rotated in the reverse direction, so that the tiles 5 on the turntable 2 hit the tile swinging-down member 19 by a fraction of a turn of the turntable 2 and fall out of the turntable 2. And the time required to complete the tile arrangement can be reduced.

[0018] Oite to the embodiments described above turntable 2
Although the single bevel gear 14 for transmitting the rotation of the rotation to the rotating frame 16 is one, it goes without saying that two or more may be arranged.

[0019]

[Effects of the Invention] Since the automatic mahjong machine of the present invention is configured as described above, even if the tiles are stuck to the surface of the turntable due to dirt or moisture, the turntable is rotated and the turntable is rotated. The tiles can be reliably shaken down within a range of a fraction of a turn of the turntable by the action of a tile swing-off member attached to a rotating frame that rotates in the opposite direction. Therefore, compared with the conventional automatic mahjong machine, there is an effect that the time until the distribution of tiles to each corner is completed can be shortened. Furthermore, the rotation of the rotating frame is equivalent to the rotation of the turntable.
Use a separate rotating frame to drive through the gear mechanism.
There is no need for a power source to turn it, and it can be produced at low cost
Both have only a gear mechanism, so the entire mahjong machine is compact
Can be configured.
