[0017]
Next, the configuration of the measurement body will be described with reference to FIGS. 2, 3, 4, and 5. FIG.
[0018]
FIG. 2 is a perspective view showing a configuration example of the measurement body, FIG. 3 shows a configuration example of the measurement body, (a) is a side view, (b) is a plan view, and (c) is another side view. 4A and 4B show one of the measurement housing and the contact measuring element. FIG. 4A is a side view, FIG. 4B is a plan view, and FIG. 4C is another side view. 5A and 5B show the other measuring housing and the contact measuring element, where FIG. 5A is a side view, FIG. 5B is a plan view, and FIG. 5C is another side view. In these figures, the measuring body 2 is composed of a pair of measuring housings 21 and 22 and contact measuring elements 31 and 32 provided at the tips of the pair of measuring housings 21 and 22 as described above. .
[0019]
One measurement housing 21 includes a base portion 210 and an arm portion 215 whose front end side is bent obliquely downward. The base portion 210 is provided with a bearing hole 21a on which a support shaft 401 is attached. Further, the contact measuring element 31 is integrally provided at the tip of the arm portion 215.
[0020]
The other measurement housing 22 is composed of a base 220 and an arm 225 whose front end is bent obliquely downward, like the above-described one measurement housing 21, and a support shaft 402 is attached to the base 220. A bearing hole 22a to be worn is provided. Further, a contact measuring element 32 is integrally provided at the tip of the arm portion 225. A groove is formed in the bent portion 226 on the distal end side of the arm portion 225, and the groove bottom surface is an elongated spring seat 227. A single spring 228 is attached to the spring seat 227. One end of the spring 228 is fixed and the other end faces the contact measuring element 32 while being biased downward.
[0021]
The contact measuring element 31 and the contact measuring element 32 have a shape obtained by dividing a substantially circular shape (a shape obtained by removing the arc portion on the side of each arm from a circular shape) as a whole in a plan view. One contact measuring element 31 has a shape formed by cutting a substantially circular shape in plan view from the center of the circle into a substantially fan shape obliquely on the upper right side when viewed from the arm 215 side. Inner side surfaces 311 and 312 are formed. Also, two surfaces 313 and 314 are formed on the upper surface, and two surfaces 315 and 316 are formed on the lower surface, and the thickness decreases toward the tip. Further, the outer surface 317 is a part of a spherical surface. The contact probe 31 is integrally provided with a fixed shaft 30 so as to pass through the center of the sphere and to be parallel to the straight direction between the obstacle nails. It protrudes from the spherical outer surface 317 of the measuring element 31, and the other end extends toward the other contact measuring element 32.
[0022]
The other contact measuring element 32 corresponds to an acute-shaped fan-shaped portion when a substantially circular shape in plan view is cut into a substantially fan shape obliquely on the upper right when viewed from the arm portion 225 side from the center of the circle, Inner side surfaces 321 and 322 are formed by cutting. The outer surface 327 is a part of a spherical surface. Further, the tip end side is formed with a large thickness and is a columnar body 323 having a high height. The upper and lower sides of the columnar body 323 are cut horizontally.
[0023]
A bearing 329 is formed by notching between the columnar body 323 and the tip of the bent portion 226. The other end of the fixed shaft 30 is received by the bearing 329, and the other end 302 of the fixed shaft 30 protrudes from the outer surface 327 of the contact probe 32.
[0024]
When measuring the distance between the pair of obstacle nails using the gaming machine nail interval measuring apparatus 1 having the above-described configuration, the fixed shaft 30 is first received by the bearing 329 and the fixed shaft 30 is pressed against the bearing 329 by the spring 228. Then, as described above, the operator brings the measuring housings 21 and 22 close to each other against the biasing force of the spring 403, and inserts the contact measuring elements 31 and 32 between the obstacle nails in this state. Then, the front end surface 318 of the contact probe 31 is abutted against the game board surface, and the fixed shaft 30 is placed close to the two obstacle nails from above. Then, the detection value of the rolling inclination sensor 45 and the detection value of the pitching inclination sensor 46 are confirmed on the LCD display unit 42, and the values are set to be “0”. At this time, the measuring body 2 is set in a posture in which there is no inclination in the vertical and horizontal directions. Measurement takes place in that position.
[0025]
As described above, in the present invention, when measuring the nail interval, the fixed shaft 30 is pressed against the bearing 329 by the spring 228, so that the other contact measuring element 32 is sufficiently supported on the fixed shaft 30 side. . Therefore, the contact measuring element 32 does not shake up and down, and the nail interval can be measured with high accuracy.
[0026]
Further, the tip surface 318 of the contact probe 31 is a part of the spherical outer surface 317 and the fixed shaft 30 passes through the center of the sphere, so that the posture of the measuring body 2 at the time of measurement is relative to the game board surface. Even if it is tilted up and down, the distance from the game board surface to the fixed shaft 30 is always kept at the ball radius. Therefore, no measurement error occurs even if there is a slight up-and-down inclination, and the measurement can be performed easily and quickly.
[0027]
Moreover, since the outer surfaces 317 and 327 of the contact measuring elements 31 and 32 are in contact with the obstacle nail at the time of measurement, and the outer surfaces 317 and 327 are spherical surfaces, the obstacle nail and the outer surfaces 317 and 327 are respectively pointed. Therefore, even if the posture of the measuring body 2 at the time of measurement is slightly deviated to the left and right with respect to the game board surface, the nail interval measurement error can be suppressed to an extremely small level, and this also facilitates the measurement. And can be done promptly.
[0028]
Further, when measuring the nail interval, the detection value of the rolling inclination sensor 45 and the detection value of the pitching inclination sensor 46 are confirmed on the LCD display unit 42, and the posture is set so that both values are “0”. Therefore, the posture can be controlled with high accuracy based on the digital value, and coupled with the fact that it is not easily affected by the above-mentioned up / down / left / right tilt, it is possible to perform measurement with very little error.
[0029]
In the above description, the fixed shaft 30 is pressed by the spring 228. However, the fixed shaft 30 may be pressed by another elastic member, for example,.
[0030]
【The invention's effect】
Since this invention consists of an above-described structure, there can exist an effect which is demonstrated below.
[0031]
In the first aspect of the invention, since the fixed shaft is pressed to the bearing side by the elastic member, the other contact probe can be sufficiently supported, and the contact probe can be shaken up and down. Therefore, the nail interval can be measured with high accuracy.
[0032]
In the invention according to claim 2, since the tip of the contact measuring element is a spherical surface, even if the posture at the time of measurement is tilted up and down with respect to the game board surface, the distance from the game board surface to the fixed axis is measured. The distance is always kept at the sphere radius. Therefore, no measurement error due to vertical inclination occurs, and measurement can be performed easily and quickly.
[0033]
Moreover, since the outer surface of the contact measuring element is in contact with the obstacle nail at the time of measurement and this outer surface is a spherical surface, the obstacle nail and the contact measuring element are in point contact. Therefore, even if the posture at the time of measurement is slightly deviated left and right with respect to the game board surface, the nail interval measurement error can be suppressed to an extremely small level, and also from this point, the measurement can be performed easily and quickly. .
