で作動を正確にすることができる。 As described above, the opening/closing mechanism of the tile drop slot in the automatic mahjong table according to the present invention configured as described above uses a motor that rotates in one direction as the drive motor for opening/closing the opening/closing operation. A crank pin that rotates in one direction is connected at one end to an operating lever that rotates to open and close the lid, and the operating lever reciprocates in an arc due to the circular motion of the crank pin. In this way, the operating lever is configured to open the lid in the forward stroke and close the lid in the backward stroke, and to turn off the motor circuit at the end position of each stroke. Since it is regulated by a limit switch, precise operation can be achieved using a simple mechanism that roughly connects the crank pin, which is rotated in one direction by a motor, the operating lever, and the lid.
