Abstract

PROBLEM TO BE SOLVED: To reduce the number of parts and assembling man-hour and to enable to simplify the constitution and to prevent a failure, by equipping an eccentric weight to a motor to vibrate by rotating the motor to cast dice by the vibration. SOLUTION: A vibration unit motor is constituted by attaching a weight 3 with the center of gravity at a position eccentric from the motor rotation axis center line onto the rotation shaft 2 of the motor M. The motor M starts rotating by pressing an actuating switch 5 and rotates for a prescribed time or a time a switch 5 is pressed down. By the eccentric rotation of the weight 3 by the rotation of the motor M, the motor M produces vibration to vibrate a dice bed 1, a case C, and dice D, D thereon. Consequently the dice D, D are jumped up and randomly rotated and thrown down. Thus the dice device can be made into simple constitution.

Embodiment 1 FIG. 1 is an overall view of an automatic mah-jong table incorporating a dice device according to the present invention, and a dice device S according to the present invention is installed at a central portion of a top plate A. FIG. 2 is a cross-sectional view of an automatic mahjong table incorporating the dice device according to the present invention. FIG. 3 is a cross-sectional view of the dice device according to the present invention.

Hereinafter, the configuration will be described in detail with reference to the drawings. On the upper surface of the machine frame W, the top board A,
A tile mixing section H, into which the game player puts the upper mahjong tiles, is provided.

A dice device S according to the present invention is installed above the tile stirring section H. The dice device S has, inside a case C, a dice base 1, one end of which is attached to the case C.
Is attached.

A weight 3 having a center of gravity is attached to the rotating shaft 2 of the motor M, at a position shifted from the center line of the rotating shaft of the motor M, to form a vibration motor unit. On the upper part of the dice stand 1, two dice D, D,
Is placed. On the upper surface of the case C, a window 4 made of transparent glass or resin and a start switch 5 for swinging the dice are provided so that the game player can see the case C and the dice D, D therein.

When the start switch 5 is pressed, an electric circuit is incorporated so that the motor M starts and rotates during a preset time or while the start switch 5 is being pressed.

In the present embodiment, the dice device is supported by a support shaft J, and is operated by a machine frame W and a cover vertical unit (not shown) provided at a lower portion thereof. At the same time, it protrudes above the top plate A, and serves as a slot for the tiles.

The operation of the dice device is as follows. When the game player presses the start switch 5, the motor M of the vibration motor unit starts and starts rotating. Since the weight 3 having the center of gravity is attached to the rotating shaft 2 of the motor M, which is shifted from the center line of the rotating shaft 2, the motor M itself vibrates. Therefore, the two dice D, D, which are placed on the upper part of the dice table and the case C, receive the vibration, are flipped up, and rotate irregularly. After a predetermined time, when the vibration motor unit stops, the two dice D, D, are displaying random numbers.

The internal configuration of the dice device is different from that of the first embodiment, and the configuration of the automatic mahjong table itself is the same as that of the first embodiment. Hereinafter, the configuration will be described in detail with reference to the drawings.

The dice device S has a dice table 1, one end of which is attached to the case C, inside a case C, and a bimorph type piezo element P is arranged below the dice table 1. The outer periphery of the bimorph type piezo element P is attached to a case C.

Two dice D, D, are placed on the upper part of the dice table 1, respectively. On the upper surface of the case C, a window 4 made of transparent glass or resin and a start switch 5 for swinging the dice are provided so that the game player can see the case C and the dice D, D therein.

By pressing the start switch 5, an electric circuit is incorporated so that an alternating current or a pulsating current flows through the bimorph type piezo element P, for a preset time or while the start switch 5 is pressed. I have.

In this embodiment, as in the first embodiment, the dice device is supported by a spindle J.
Machine frame W, lid up / down unit provided at lower part (not shown)
With this operation, it protrudes above the top plate A, together with the support shaft J, and serves as a slot for the tiles.

The operation of the dice device is as follows. When the game player presses the start switch 5, an alternating current flows through the bimorph piezo element P, and the bimorph piezo element P is vertically deformed. The vertical deformation of the bimorph type piezo element P, is transmitted as vibration to the dice table 1, and the dice D, D, on the dice table 1, are also vibrated, are flipped up, and rotate irregularly. After a predetermined time, when the bimorph type piezo element P, stops, the two dice D, D, are displaying random numbers.

If an electric signal to which a sound frequency is added is given to the bimorph type piezo element P, it can be used as a speaker, and can also be used as various kinds of sound information devices during the progress of a game.
