Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail angle measuring device of a pachinko machine for measuring an angle between a board surface of a game board of the pachinko machine and a nail protruding from the board surface.

[0002]

A large number of nails are arranged on a board surface corresponding to a game section of a game board of a pachinko machine.
Among these many nails, there are one that is relatively densely arranged to set the course of the game ball, and one that is arranged above various prize winning devices at intervals allowing the game ball to pass. The latter nail is projected in various directions with respect to the board surface at various angles,
This angle affects the ease of entering the winning device. This time, when manufacturing and selling a pachinko machine, a request was made to accurately measure the angle of the nail placed at a predetermined position among the nails placed above the winning device (the minimum unit is 1 degree). there were.

However, since the nail can be tilted in any direction of 360 degrees with respect to the board surface of the game board,
Even if an instrument generally used for measuring the angle, such as a protractor, is used, the angle cannot be accurately measured in consideration of the direction in which the nail is tilted. On the other hand, fairness 3-56
It is conceivable to measure the angle of the nail projecting on the game board surface by the game machine adjustment driver disclosed in Japanese Patent No. 484. However, since this driver is equipped with a spirit level and measures the angle of the nail by the air bubbles inside the level, it can measure only the vertical component of the nail angle, and the angle other than the vertical direction can be measured. Could not be measured. Also,
The spirit level is inaccurate because it teaches the angle by the bubbles in the spirit level.

The present invention has been made in view of the above circumstances, and an object thereof is to measure a nail angle of a pachinko machine capable of accurately measuring an angle of a nail projecting in various directions on a board surface of a game board. To provide the equipment.

[0005]

A nail angle measuring device for a pachinko machine according to the present invention is a fixing member having a circular hole arranged above a nail projecting on a game board, and a circular hole in the fixing member. A rotating member that is rotatably provided in a state parallel to the board surface of the game board, and is provided so as to be swingable along the inclination direction of the nail, and the upper end portion intersects with the rotating member,
A swinging member having a substantially rod shape that makes the side portion of the lower end portion closely contact with the nail, a surface of the rotating member or the swinging member that is in close contact with the nail, and the game board. And a scale portion for reading an angle between the board surface and the board surface (claim 1).

In this case, the rotary member is formed in a dome shape so as to close the circular hole of the fixed member, and a slit is formed so as to pass through the center of the rotary member and extend in the radial direction. It can be configured to guide the upper end of the swing member (claim 2). Further, it is preferable that a scale for reading the rotation angle of the rotating member is provided on the outer peripheral edge of the circular hole of the fixing member (claim 3).

1 is configured to be fitted so as to sandwich both upper and lower sides of the support plate 32. As a result, the movable plate 37 becomes the support plate 32.
You can move the top left and right freely. Then, when the support plate 32 on which the movable plate 37 is mounted is hung over the game board 31, the movable plate 37 is configured to be held in parallel with the board surface P of the game board 31. . Further, since the support plate 32 can freely move in the vertical direction on the game board 31 as described above, the movable plate 37 is arranged above any of the nails 36 protruding from the game board 31. be able to.

An annular groove 38b (see FIGS. 9 and 10) is provided on the inner peripheral surface of the circular hole 38 of the movable plate 37, and both ends of the rotary shaft 39 can slide in the groove 38b. Is fitted to. As a result, the rotary shaft 39 can freely rotate within the circular hole 38 of the movable plate 37.

On the other hand, the swinging member 40 is substantially rod-shaped as a whole, and the shaft portion 36a of the nail 36 is provided on the side surface of the lower end portion.
Is provided with a nail contact portion 42 for closely contacting with each other, and a groove portion 42a into which the shaft portion 36a of the nail 36 is fitted is formed in the nail contact portion 42. A circular scale reading unit 43 protruding above the movable plate 37 is provided in the upper half of the swinging member 40. The circular scale reading unit 43 is rotated in a through hole formed in the center of the scale reading unit 43. The shaft 39 is inserted. A recess 42b is formed in the upper portion of the nail contact portion 42, and the head 36b of the nail 36 is fitted into the recess 42b. Thereby, the nail 36
The head portion 36b of the nail 36 does not get in the way when the shaft portion 36a is brought into close contact with the groove portion 42a of the nail contact portion 42. Further, as shown in FIG. 9, the scale reading unit 43 is swingable around the rotation shaft 39, and a large number of scales 43a are provided on the outer peripheral edge portion. This scale 4
3a is not shown in detail, but 15 scales 43a are placed once on both sides of "0" indicating that the nail contact portion 42 is perpendicular to the board surface P of the game board 31. It is provided in.

As shown in FIG. 6, the graduation reading section 43 is provided with a graduation reading line 43b located at the center of the outer peripheral surface, and the graduation reading line 43b calibrates the graduation 38a of the movable plate 37. By reading, the rotating shaft 3
