Description

[Detailed description of the invention] This invention utilizes a device that automatically stirs the mahjong tiles inside the table. This invention relates to a three-person mahjong mechanism in which the tiles are arranged on a table so that three people can easily play the game in a sending device having a mechanism for vertically dropping the tiles from a provided drop opening.

Traditionally, tiles in mahjong games were stirred by the hands of the player, but in recent years, stirring by hand is not only troublesome, but also a waste of time and is accompanied by noise. Devices for automatic stirring inside the table are now available.

Normally, mahjong is played by four people, but if there is one player missing, there is a game method called three-person mahjong, which is commonly known as three-person mahjong. Compared to the game using 136 tiles, in the case of three-person mahjong, it is impossible to play with 136 tiles, so 24 tiles or 28 tiles are used instead of 136 tiles.
This was done with the exception of a few points.

However, as mentioned above, since fully automatic mahjong tables have been provided for four players, it is not possible to arrange them for three-player mahjong, and therefore automatic stirring and automatic alignment for three-player mahjong are not possible. In order to meet this demand, one of the four tile dispensing devices that receives vertically falling tiles from the four falling sections is used as a three-person mahjong unit. A mechanism has been provided in which a solenoid is actuated via a computer to temporarily shut off the drop opening of the human mahjong unit. Trouble often occurred between the tiles and the rotating disk of the stirring device.

Therefore, in order to solve the above problems, this invention
The tiles placed on the tile holder are sent out from the tile drop opening.The difference in movement between the tile holder and the tile feeder is temporarily canceled and the tiles are reciprocated with the tiles placed on the tile holder. The drawings will be described in detail below.

Figure 1 is a perspective view of the three-person mahjong unit, Figure 2 is a longitudinal cross-sectional view of a part of the stirring device and the three-person mahjong unit seen from the side, and Figure 3 is a longitudinal cross-section of the three-person mahjong unit seen from the side. Figure 4 is a plan view of the internal structure of a fully automatic mahjong table using the present invention, Figure 5 is a vertical sectional view of a three-person mahjong unit seen from the front, and Figure 6 is a selection of fully automatic mahjong tables. It is a perspective view of a switch part.

In the figure, A is the table of the fully automatic mahjong machine, B is the rotating board of the fully automatic mahjong table, C is the main body of the three-person mahjong unit,
D is a transport device that arranges the tiles sent out from the unit into two stacks, S is a selection switch, U, U ₁ ,
U ₂ and U ₃ are units, 1 is a tile drop port, and when the tiles stirred on the rotary plate B fall one by one,
A magnet installed in the side serves to align the tiles on the tile holder with the tiles facing in the positive direction.

Reference numeral 2 denotes a tile feeding stand, which serves to send the tiles that fall from the tile drop opening forward, and is linked to the tile holder 3 by means of a linkage spring 6 installed inside. There is.

3 is a tile holder, on which fallen tiles are placed in the tile feeder 2, and due to the difference in movement with the interlocking tile feeder 2, only the tiles are lined up on the conveyor sent forward. 4 is a guide portion that guides the tiles sent forward onto the conveyor.

Reference numeral 5 denotes a tile holder stopper, which functions to stop the tile holder 3 interlocked with the tile feeder 2 in the middle, so that only the tile feeder 2 is sent out, creating a difference in movement.
When playing three-person mahjong, the changeover switch is switched, and the solenoid is de-energized and lowered by a command from the computer, eliminating the difference in movement, and the tiles are stacked in two layers on the tile holder and repeatedly move back and forth. It's becoming like that.

6 is a linkage spring that constantly pulls the tile feeder backward.

7 is a lever that slides the tile feeder 2 and tile holder 3 back and forth.The tile feeder 2 and tile holder 3 are sent out using the motor of the fully automatic mahjong table as the driving force, and the coil spring 8
It is starting to come back to normal.

Reference numeral 9 is a solenoid, and as mentioned above, when using a fully automatic mahjong table for three-person mahjong, the tile holder stopper 5 is activated by a command from a computer that has stored the three-person mahjong system by switching the changeover switch. By lowering the tiles, the difference in movement between the tile holder 3 and the tile feeder 2 is eliminated, and the tiles stacked in two tiers on the tile holder of the three-person mahjong unit repeat reciprocating movements while remaining as they are.

Next, a case where three-person mahjong is played using the present invention having the above configuration will be described.

Three-person mahjong differs from four-person mahjong in that there are two ways to play.

In other words, in the case of 24 tiles removed, the number of tiles used is 112, and 102 tiles are arranged in three rows east-southwest with 34 double-stacked tiles in one row, and five sets of the remaining 10 tiles are stacked in two rows to the north. There must be.

In addition, if 28 tiles are drawn, the number of tiles used is 108, and 102 tiles (34 tiles) stacked in two stacks are lined up in the east-southwest direction, and three sets of the remaining 6 tiles stacked in two stacks are lined up in the north. Must be.

In order to arrange the tiles in this way, in the present invention, the selection switch S for the number of tiles to be drawn (24 or 28, etc.) is switched in advance, and the solenoid of the three-person mahjong unit U is energized. Then, release the tile holder stopper 5 provided on the unit body C that engages with the tip of the solenoid, and as shown in FIG. 3,
As the tile holder 3 and the tile feeder 2 repeatedly move back and forth over the same distance, there is no difference in movement between them, and no tiles are pushed out.

However, the other three units send out the tiles, stack them in two tiers, line up in the east-southwest direction as described above, and wait, and when they reach the remaining three or five pairs of tiles in the two tiers, the computer In response to this command, the tile holder stopper 5 returns to its original position, the four sending devices stop operating, and the arrangement of tiles for three-person mahjong is completed.

The two control commands for three-person mahjong, namely method A for 24 pieces and method B for 28 pieces in three-person mahjong, operate the tile holder stopper 5. If it is stored in the memory circuit of the computer, it can be easily selected by switching the selection switch S as necessary.

As mentioned above, the present invention utilizes the four-way tile feeding device of a fully automatic mahjong table, and stores the control system necessary for three-person mahjong in the memory circuit of the computer, thereby creating the A method for three-person mahjong. , is a unique three-person mahjong mechanism that can also stir and send out tiles in addition to the B method.
