Description

[Detailed explanation of the idea] [Industrial application field]

The present invention was developed to enable automatic mahjong machines to roll out dice on the mahjong table at the beginning of the game without touching the dice directly. This invention relates to improvements to an automatic dice dispensing device in an automatic mahjong table installed in a machine.

[Conventional technology]

The above-mentioned automatic dice dispensing device that is installed on the automatic mahjong table is intended to roll the dice and roll out the dice without touching the dice, thereby ensuring that the dice roll out fairly. Since the dice are enclosed in the hopper so that the dice stored in the hopper can be rolled without touching them, the dice cannot be replaced, and special dice can be rolled by inserting flower tiles. There was a problem that became an impediment when playing games using it. In addition, the operation of rolling out the numbers of the dice enclosed in the hopper supports the bottom plate of the hopper, which supports the dice, on the upper end of the vertical axis of rotation rotated by the operation of the motor, so that the bottom plate of the hopper is vertically rotated. Since the operation is performed by rotating around the rotation axis in the direction,
When the bottom plate of the hopper is rotated, the die becomes in a state of continuous rotation like a top with a fixed axis of rotation based on its unique weight balance, and then the bottom plate of the hopper stops rotating and becomes stationary. There is a problem in that the changes in the numbers rolled by the dice that have been rolled are biased. The present invention was devised to solve these problems that have arisen with conventional means, and the automatic dice dispensing device installed in the mahjong table of an automatic mahjong table can be easily operated in the assembled state. The objective is to propose a new means for exchanging dice and ensuring that the rolls of the dice are random.

[Means to solve the problem]

In the present invention, as a means to achieve this objective, a cylindrical hopper for accommodating the dice is placed on the bottom side of a cover with a window hole in the center, and an opening on the top side of the hopper. The opening is formed integrally and continuously with the window hole of the facing cover so as to hang downward, and the opening is formed at the inner side of the window hole at the edge of the opening on the upper surface side of the hopper. An annular step is formed to support a glass plate that covers the glass plate and a ring-shaped presser frame that presses the glass plate, and the step has an engagement portion that engages and disengages with an engaging portion provided on the presser frame of the ring. An engaging part that can be engaged freely is formed, an assembly part is installed at the bottom of the hopper, and the bottom plate is vibrated by an electromagnet acting on a permanent magnet provided on the lower surface of the bottom plate of the hopper. The present invention proposes an automatic dice dispensing device equipped with a vibration device.
