The rack 156 meshes with a pinion 157 fitted to the drive shaft of a deceleration motor M5 attached to the framework 151 via a torque limiter 158.

Note that the base body 150 has a conveyor comparator +7 on the extrusion slope 152.
Fifteen stoppers fixed to the base body 150 and protruding above the conveyor 7 are provided on the downstream side of the conveyor 7 . Therefore, by positioning the pushing plate 152 behind the wall tile alignment section and driving the motor M4, the mahjong tiles 2 are brought into contact with the striker 159 and are pushed out (9+1=) on the conveyor 7. The limit switch S2 of the wall tile alignment section 27 detects the completion of extrusion by the wall tile alignment section 27, and upon this detection, the deceleration motor M2 is driven, and the extrusion section 149 is manually operated. The mahjong tiles 2 can be pushed out to the hand tile alignment section 28 by moving the tile alignment section 28 to the rear position and operating the push-out ramp 152. Furthermore, upon detection of the detection P5S, the push-out board 152 stops and the push-out section 149 returns to the position of the wall tile alignment unit 27. In this way, the extrusion odor 9 of this example is caused by the alignment and lifting device r11.1.
You can push Mahjong tile 2 to 0 with a prayer.

The same Vk drive J of the rotating body 17 and the carry-in conveyor 7 is as shown in FIG.
2 can also be formed by connecting them via a transmission mechanism 80 such as a gear.

〔Effect of the invention〕

As mentioned above, in the tile distribution device of the automatic mahjong table of the present invention, a sending conveyor is provided in the tile take-out L7 tool provided in the hot-handling device τ, and a conveyor is arranged on the conveyor and a lifting device is arranged on the conveyor. In addition to installing a pusher to push out the mahjong tiles, we also installed a detector that detects the extrusion function of the pusher and moves the conveyor backwards once the extrusion is completed, making it possible to immediately return surplus mahjong tiles when the alignment is complete. (In order to prevent the entry of many mahjong pieces, it is possible to complete the alignment of all the mahjong tiles in a short time, and the waiting time for the game can be greatly shortened.Also, the mahjong tiles can be aligned at the player's hand, This makes it possible to reduce the amount of movement of the aligned tiles, such as wall tiles and hand tiles, unlike in conventional devices, thereby increasing alignment accuracy and making the device easier to sell.

Note that a chain conveyor using a so-called top plate chain may be used instead of the belt conveyor, and the alignment and lifting device may be configured to align only the wall tiles, and the detector may be The extruder can be attached to the extruder in such a way that the completion of extrusion can be detected by counting the number of extruded mahjong tiles, and the present invention can be modified in various ways.
