Further, the tile arranging device 4 which can be stored in the machine casing 1 has the same structure as the conventional one shown in FIG. Referring to FIG. 4, a drum-shaped hopper 40 that receives the mahjong tiles P ... Dropped from the tile drop opening 30 of the mahjong table 3 is installed in the central portion, and the bottom portion thereof is shown in FIG. As shown in FIG. 6, a mahjong tile P is supported by a built-in magnet at the peripheral portion of the upper opening of the hopper 40, which pivotally supports the turntable 43 that tilts and rotates about the tilted support shaft 43a. A suction ring 44 for sucking is attached. Then, a transfer conveyor 45 that inherits the mahjong tiles P adsorbed by the adsorption ring 44 and carried out to the outside of the hopper 40 at a part of the peripheral portion is shown in FIG.
, The front end of the transport path u faces the end of the transport conveyor 45, and the mahjong tile P
A two-stage stacking device 41 for stacking the two in a stack and sending them to the transport path u is provided. In the transport path u, when the mahjong tiles P .. The transport means 46 is provided, which is configured by providing a feed pin to an endless chain that operates to sequentially feed the four lifts 42 ...
Pushing devices 47 for pushing the aligned mahjong tiles P ... to the upper surfaces of the lifts 42 ... Are arranged at positions on the opposite side of the portions adjacent to the lifts 42 ... It is a conventionally known one.

A lid plate 31 installed so as to open and close the drop opening 30 which is opened in the central portion of the top plate 3a of the mahjong table 3.
The means for opening and closing is to divide the columns 32 of the lid plate 31 into a plurality of columns, and arrange the columns 32 ... In a ring shape surrounding the central portion of the lid plate 31 as shown in FIGS. 7 and 8. The lower end of each of the columns 32 ... Is a pipe-shaped guide column 71 that is erected on a lower block 70 that is fixedly installed in the machine frame 1.
... is slidably fitted to the lid plate 31 so that the lid plate 31 can be moved up and down by these sliding movements, and a spring 72 stretched between the lid plate 31 and the lower block 70 allows the lid plate 31 to be normally lowered. Urge to occupy. And this lid plate 3
A flexible outer pipe 73 is arranged in the central portion of the lower surface of 1, and the upper end portion of the outer pipe 73 is fixedly supported by the guide column 71 via a support fitting 74 to be held in a vertical posture. The bottom side of the machine frame 1 to the bottom wall 1a
Is bent along the upper surface of the device so that the free end is arranged in the machine frame 1 so as to be driven and rotated by the drive motor M1 so as to face the vicinity of the entrance / exit operation mechanism W.
One end side of an inner wire or flexible pipe 75 formed to have a diameter that can be inserted into and removed from the inner cavity of the outer pipe 73 is connected, and the other end side of the inner wire or flexible pipe 75 is inserted into the outer pipe 73. The other end of the adjusting pipe 76 is inserted and protrudes upward from the upper end of the outer pipe 73 that is held in a vertical posture, and is attached to the lower end of the adjusting screw 76 that is screwed into the central portion of the lid plate 31. By connecting and operating the entrance / exit operation mechanism W by driving the drive motor M1 to push out or pull in the inner wire or the flexible pipe 75, the lid plate 31 rises as shown in FIG. 9 to open the drop port 30. The state is switched to the state in which the lid plate 31 descends to close the spill port 30 as shown in FIG.

In this embodiment, the in / out actuating mechanism W is provided with a crank pin 80 serving as an actuating portion on a crank wheel 80 rotated by a drive motor M1, and a flexible wire or a flexible pipe 75 is provided on the crank pin 81.
It is configured by connecting one end side of the. The rotation of the crank wheel 80 by the drive motor M1 is shown in FIG.
In this case, the counterclockwise direction is set as shown by arrow a. Further, the notch portions 82, 82 are formed on the peripheral surface of the crank wheel 80 with a phase difference of 180 degrees, and the operating piece of the limit switch SW is fitted into the notch portions 82, 82 to turn off the circuit of the drive motor M1. By doing so, the crank wheel 80 is stopped at the position where the inner wire or the flexible pipe 75 is pushed out and the position where the flexible pipe 75 is pulled in, and by driving the drive motor M1 from that state, the crank wheel 8
It is controlled so that it will stop again when 0 rotates 180 degrees.

In order to prevent the tiles P, which are pushed into the transport path u of the tile aligning device 4, from collapsing while being transported by the transport means 46 toward the positions adjacent to the lifts 42. The collapse prevention cushion 5 installed on the
As shown in FIG. 6, the mahjong table 3a of the mahjong table 3 is located above the transport path u, and the top board 3a is used as a support for the mahjong table 3a. It is mounted and supported so as to be in sliding contact with the upper surface of the tile P, so that when the mahjong table 3 is opened and rotated, the cushion 5
Is rotated upward together with the mahjong table 3 to completely open the upper part of the transport path u so that maintenance around the transport path u can be performed without trouble.

In the illustrated embodiment, 9 is a supporting leg which is detachably or foldably attached to the lower surface of each corner portion of the machine frame 1 formed in the shape of a rectangular flat box.

[0015]

As described above, in the automatic mahjong table according to the present invention, the tile arranging device 4 prevents the tiles from collapsing when the aligned mahjong tiles P ... Are conveyed to the standby position by the conveying path u. By attaching the collapse preventing cushion 5 to the lower surface of the top plate 3a of the mahjong table 3 and slidingly contacting the upper surface of the aligned mahjong tiles P ... in the transport path u, the mahjong tiles P can be pressed down. This eliminates the need for the support plate for the collapse prevention cushion and the mechanism for opening and rotating the cushion, which were mounted on the conventional automatic mahjong table. Therefore, the upper and lower thicknesses of the machine frame 1 can be reduced by the amount corresponding to the support plate for the collapse prevention cushion and the mechanism for opening and rotating the support plate.
