2. Description of the Related Art Mahjong, which uses fingertips and changes in game contents, has recently been attracting attention as one that both plays a role of preventing aging and recreation of elderly people. There is a setting of Mahjong tiles as an operation that needs to be performed even though it is not a game itself in Mahjong, but since this setting is relatively troublesome, automatic setting by automatic machines has become popular recently. Although this automatic machine is generally used for business because it is expensive, it is very useful for elderly people who are becoming difficult to perform various operations to perform mahjong.

On the other hand, even though it is an important matter for the progress of the game, the points of each person who is playing the game are counted and verbalized by each person even in the situation where such an automatic machine is widespread. However, there is no device that automatically counts your points.

In order to cope with such a situation, the present inventors have proposed, in Japanese Patent Application No. 4-162747, in a mahjong game, a tray accommodating a score bar for each of the four game players according to the progress of the game. The invention of a mahjong score counting system has been provided, in which the weight of a score bar is detected by a weight measuring device attached to and the number of points is calculated automatically by the weight of the score bar. In the mahjong score counting system and the mahjong table used in this mahjong score counting system, the weight of each game player's score bar is measured to count the number of each score bar and calculate the score. First, the mahjong score counting method and the mahjong table will be described.

FIG. 1 is a conceptual diagram for explaining a mahjong score counting system, in which 1, 2, 3, and 4 are score bar trays, and 5, 6, 7, and 8 are score bar trays. A weight sensor for measuring the weight, 9 is a score bar, 10 is a central processing unit that calculates the weight of the score bar measured by the weight sensor as a score, and 11, 12, 13, and 14 are score points of each gamer. It is a display device including an LED or the like for displaying.

Each of the weight sensors 5, 6, 7, and 8 sends a signal corresponding to the weight of the point bar to the central processing unit 10, and the central processing unit 10 processes the signals sent from the respective weight sensors to process the signals. The player's points are counted and the result is displayed on the display device 1
Displayed at 1, 12, 13, and 14.

FIG. 2 shows that the weight of each of the four game players is detected by a weight sensor attached to a tray that stores the score of each of the four game players as the game progresses. It is an automatic counting mahjong table that automatically calculates points by weight. This mahjong table is
The mahjong score counting system is applied to an automatic machine having a mahjong tile automatic setting mechanism (tile setter), and a weight sensor 5, which measures the weight of the score rods on each score rod tray 1, 2, 3, 4. 6, 7 and 8 are attached, the signal thereof is sent to the central processing unit 10 attached to the mahjong table, and the resulting points are provided to the display devices 11 and 12 facing the respective game players. , 13, 14 are displayed.

The present invention relates to a concrete construction of a mahjong table to which the mahjong score automatic counting method described in the above-mentioned Japanese Patent Application No. 4-162747 is applied.

The mahjong table according to the present invention detects the score of each of the four gamers according to the progress of the game by a weight sensor attached to the tray storing the score bar, and calculates the score by the weight of the score bar. . Therefore, when a force element other than the weight of the point bar, for example, an impact or a vibration is applied to the weight sensor, an error occurs in the measurement and the reliability of the displayed point is lost. In particular, since most commercial mahjong recently have a tile setter, vibrations that occur when the tile setter operates cannot be ignored and are applied to the weight sensor.

FIG. 4 shows an outline of the mechanism for attaching the frame to the mahjong table body and the internal structure of the frame. The automatic point counting mahjong table shown in these figures is an example applied to a mahjong table having a tile setter, a leg part 21 is attached to the mahjong table body 20, and the mahjong table body 20 has a frame 22. Is attached. A metal fitting 27 for supporting the frame 22 is attached to the lower portion of the mahjong table body 20, and the frame 22 is placed on the metal fitting 27. Inside the frame 22, there is formed a space 26 indicated by a broken line that is large enough to accommodate the mahjong table main body 20, and on the outer periphery of the frame 22, a score bar box for storing the score bar, and the weight of the score bar are measured. A weight sensor, a point display device, an operating unit, and a central processing unit (CP that controls them)
U) is housed.

A scoring bar box 23 for accommodating a scoring bar is provided in the center of the side surface of the frame 22, and a score display device 24 and an operating section 25 are provided on the upper part of the side surface. Also, the leg 2
A cushioning member 29 made of a vibration-proof rubber or the like is attached to the upper surface of the attaching portion 28 provided on the upper part of the unit 1.

FIG. 5 shows the mahjong table body 20, metal fittings 27, and frame 2.
2, a partial cross-sectional view illustrating the relationship among the score bar box 23, the weight sensor 42, and the tray 40 that accommodates the score bar in the score bar box 23. The metal fitting 27 is attached to the upper surfaces of the end portions of the metal plates 31 and 32, the rubber plates 32 and 33 connecting the metal plates 30 and 31, and the frame 22 is mounted thereon. It consists of

The point bar box 23 provided at the center of the side surface of the frame 22 is a front plate 37 protruding to the side surface of the frame 22 as a clue for opening and closing the point bar box 23, and a tray 40 for accommodating the point bar.
And a storage frame 38. The tray 40 is stored in a storage frame 38, the storage frame 38 is fixed to a front plate 37, and the lower end of the front plate 37 is directly attached to the lower side surface of the frame 22 by a hinge 39 so as to be rotatable. .

A base 41 is formed at the bottom of the frame 22, and a weight sensor 42 is mounted on the base 41. A magnet 43 is attached to the upper surface of the weight sensor, and the magnet 43 attracts a magnetic piece 44 provided on the lower surface of the tray 40 to stably support the tray 40 on the weight sensor.

A specific structure of the metal fitting 27 will be described with reference to FIGS. 6 (a) and 6 (b). The metal fitting 27 is composed of the two metal plates 30 and 31 as described above. The two metal plates 30 and 31 have an L shape as shown in (a), and the width of the metal plate 30 is almost half that of the metal plate 31. In addition, these metal plates 30 and 31 are vibration-proof rubbers 32, 33, 3 having a truss structure as shown in (b).
It is connected by 4,35. L of wide metal plate 31
Another anti-vibration rubber 36 having a truss structure is attached to the center of the character.

When the tile setter operates to play a game while using the automatic score counting mahjong table having such a structure, vibration is generated from the tile setter. Vibration also occurs when the player arranges tiles. These vibrations are transmitted to the mahjong table body 20 to which the tile setter is attached, and to the metal plate 30 of the metal fitting 27 directly attached to the lower part of the mahjong table body 20.

On the other hand, the weight sensor 42 which does not want to give vibrations
Is attached to a frame 22 which is a separate body from the tile setter which is the vibration source. The frame 22 is placed on the metal plate 31 of the metal fitting 27 with the anti-vibration rubber 36 interposed, and between the metal plate 31 and the metal plate 30 directly attached to the lower portion of the mahjong table body 20. The anti-vibration rubber 32, 33,
34 and 35 are interposed, and thus the double vibration-proof structure is adopted. Therefore, the vibration transmitted to the metal plate 30 is not transmitted to the weight sensor 42, and the displayed points are not erroneous.

FIG. 7 shows another embodiment in which an error due to vibration does not occur in the score display. In the embodiment shown in FIGS. 5 and 6, the entire frame 22 to which the automatic point counting device including the weight sensor 42 and the like is attached is attached to the mahjong table body 20 via a double anti-vibration rubber. It has been placed. However, it may not be possible to eliminate an error due to vibration or impact directly applied to the frame by the game player by this vibration isolation mechanism.

In that case, if the weight sensor itself is supported by the vibration isolating rubber 32 'as shown in FIG. 7, the vibration or impact applied to the frame 22 is caused by the vibration isolating rubber 32'. Since it is absorbed and is not transmitted to the weight sensor 42, it is possible to eliminate an error due to vibration or impact directly applied to the frame. This anti-vibration mechanism may be used in combination with the anti-vibration mechanism for the frame 22, but may be performed independently to simplify the anti-vibration structure.

In this embodiment, the vibration-proof mechanism using the vibration-proof rubber is used. However, as the vibration-proof mechanism, a vibration-proof mechanism in which another elastic body such as a metal spring and a vibration-damping member are combined is adopted. Of course, it is possible.

As is clear from the above description, in the automatic score counting mahjong table of the present invention, the weight sensor which is a sensor for counting the score does not transmit the vibration or shock generated by the tile setter or the like. Therefore, measurement error does not occur in the score display of the automatic score counting device.

[0024]

As is apparent from the above description, the automatic score counting mahjong table of the present invention, in which the automatic score counting device is incorporated in the frame covering the main body of the mahjong table, and the vibration is not transmitted to the weight sensor, Since the vibration generated from the tile setter and other parts is not transmitted to the weight sensor, there is no error in the displayed points.
