[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mahjong dot stick and a dot stick calculator for calculating the stick.

[0002]

2. Description of the Related Art Conventionally, mahjong is a combination of pies that are raised to compete for the total score. The points are paid and received by a mahjong dot stick (hereinafter simply referred to as "dot stick"), and the person who plays the game must always know his or her own score. Therefore, the person who plays the game quickly calculates the total score of the four types of point bars stored in the container between the games.

[0003]

However, in the middle of the game, it is very troublesome and troublesome to calculate the total score of the point rods mixed and stored in the narrow container.

The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a mahjong dot stick that anyone can easily know the score and a dot stick computing device that calculates the stick. .

And a calculation display unit for calculating and displaying the total points of the mahjong dot sticks stored in the container based on the measurement results. The resistance between the electrode plates has substantially the same resistance value as the combined resistance value when the rod is housed.

[0007]

According to the mahjong dot stick according to the first aspect, a resistor having a resistance value corresponding to the number of dots of the dot stick is built in the dot stick body. Then, when calculating the score of the dot bar, if the resistance value between both terminals exposed from the dot bar body is measured, the score can be mechanically calculated from the resistance value.

According to a second aspect of the present invention, when the mahjong point stick according to the first aspect is housed in the container, the corresponding electrode plate provided in the container is moved from the point bar body to the corresponding electrode plate. The exposed terminals are electrically connected to each other. Moreover, the resistance value between the two electrode plates is measured by the calculation display unit, and the total number of points of the dot bars housed in the container is calculated from the measurement result of the resistance value, which can be calculated and displayed.

Further, the container 20 is in the shape of a box having an upper opening, and its width is slightly wider than the length of the mahjong dot stick 10 to be stored. Further, at the bottom of the container 20, both electrode plates 21, 21 are laid along the side wall in the width direction.

As shown in FIG. 5, the two electrode plates 21 and 21 are integrally formed with a rising portion 21b and a pin 21c, and are formed in one side wall of the container 20 through insertion holes 22b and 2b.
The electrode plate 21 side is inserted into the container 20 from 2b so as to be laid on the bottom surface of the container 20.

When the electrode plate 21 is laid along the bottom surface of the container 20, the rising portion 21b is fitted into the insertion port 22b to close the insertion port 22b and the pin 21c is inserted into the container 2.
It is designed to be projected from the wall surface of 0.

The combined resistance RZ of 0 is converted into a voltage, and this voltage conversion circuit 3
The A / D conversion circuit 38 converts the voltage converted by 7 into a digital signal. Then, the conversion table for the microcomputer, the combined resistance RZ, and the points is written in R.
The point conversion circuit 39 including the OM converts the input digital signal into point data based on the conversion table and outputs it. This output is sent to the liquid crystal display unit 40 and the score is displayed on the liquid crystal display plate 36 via the liquid crystal driver 43.

Specifically, for example, a 100-point bar 1
When one 0 and one 1000 point rod 10 are stored in the container 20, the value of the combined resistance RZ of all the point rods 10 is 9.1 × 1.
The voltage becomes 0 ³ Ω, and the voltage conversion circuit 37 converts this resistance into a terminal voltage of 4.5 v. Then, the converted voltage is converted into a score of 1100 based on the conversion table and is displayed on the liquid crystal display panel 36 as 1100 points.
