Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt measuring instrument for pachinko machines. More specifically, the present invention relates to a tilt measuring device capable of measuring the tilt of a board on which nails of a pachinko machine are implanted.

[0002]

2. Description of the Related Art In a pachinko machine, the tilt of the table is an important factor that influences the ball throw rate as well as the distance between the nails. Therefore, when installing the stand, the tilt of the stand is proper (usually, the angle at which the upper end side of the stand is slightly tilted backward with respect to the lower end side).
Therefore, it is necessary to install the table while measuring the inclination of the table. Conventionally, in order to measure the tilt of the table, as shown in FIGS. 10 and 11, a bubble-type level 1 is provided on the front surface of the table 1.
01 is installed, the position of the bubble 102 in each stage is read by the scale 103, and the inclination of the table 1 is measured.

As shown in FIG. 13, the board 8 having the so-called decorations 7 such as nails 6 and tulips is housed in the glass 5, so that the tilt of the board 8 should be properly adjusted. It is desirable to install the stand 1. However, in the conventional tilt measurement using the level 101, the level 1
Even if it is attempted to measure 01 itself in contact with the board 8, it is difficult to directly measure the inclination of the board 8 because the nails 6 and the wrinkles 7 of the board 8 interfere.

An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide an inclination measuring device for a pachinko machine capable of directly and accurately measuring the inclination of a board provided with nails or a wrinkle. .
