Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game board surface tilter used for measuring the degree of tilt of a game board surface of a pachinko game machine, a coin game machine or the like.

[0002]

2. Description of the Related Art Conventionally, when measuring the degree of inclination of a game board surface of this type, a cavity is provided in a transparent synthetic resin container, and a liquid and a gas that becomes bubbles are enclosed in the cavity. A bubble type level in which the inner surface of the cavity is formed into a curvature surface that depends on the contact portion that contacts the game board surface to be measured, and the vessel is provided with an inclined scale indicating the inclination degree of the game board surface depending on the position of the bubble. The contact portion of this bubble type level is brought into contact with the game board surface to be measured, and the degree of inclination is measured by reading the bubble position at this time with an inclined scale.

The curvature surface, which is the inner surface of the cavity, is formed in a symmetrical curvature surface with the vertical position of the game board surface as a boundary, whereby three angles of forward tilt angle, vertical degree and backward tilt angle of the game board surface are formed. It is configured so that it can measure a specific area.

[0004]

However, in the measurement of the inclination degree of the game board surface of this type, the vertical inclination of the game board surface and the rearward inclination in which the lower side portion of the game board surface protrudes toward the player side more than the upper side portion Although the angle may be measured, there is almost no need to measure the forward tilt angle where the lower side of the game board surface recedes farther from the player than the upper side, that is, the vertical degree and backward tilt angle of the game board surface. It is sufficient to be able to measure the two areas of the above, and the existence of the curved surface having the three areas may complicate the manufacturing and reduce the manufacturing accuracy of the curved surface, which in turn increases the manufacturing cost. In addition, there is a disadvantage that the convenience may be deteriorated due to the existence of the unnecessary measurement region.
