Description

  The present invention relates to an obstruction member inclination measuring device for measuring an inclination angle of a nail (obstruction member) protruding from a board surface of a gaming machine, and in particular, an imaginary set by a base portion in contact with heads of a plurality of nails. The present invention relates to an obstacle member inclination measuring apparatus capable of easily and accurately measuring an inclination angle of a nail with respect to a reference surface.

Various game machines that use a spherical game medium (for example, a pachinko ball or the like) such as a pachinko machine, an arrange ball machine, and a sparrow ball machine are known.
For example, as shown in FIG. 9, on the board surface 110 of the pachinko machine 100, a game symbol 130 such as a prize winning port 131, a starting port 132, and a big prize winning port 133, and a variation symbol display device 140 that displays a state in which symbols vary. A large number of nails 10 projecting from the board surface 110 are arranged.
Of these, about 200 to 300 nails 10 serving as obstruction members are usually distributed or arranged in rows at predetermined positions on the board surface 110.

The nail 10 changes the traveling direction of a game medium (not shown) that falls from above the board surface 110 of the pachinko machine 100, and is particularly provided above the opening of the game component 130 where the game medium wins. The pair of nails 10 (so-called life nails 11) have a great influence on the probability of winning the game component 130 by their opening degree (usually the horizontal inclination angle) and the vertical inclination angle. Incidentally, the larger the opening degree, the easier it is for the game medium to win, and the more the game is inclined upward, the easier it is for the game medium to win.
However, since the nail 10 is repeatedly collided with a large amount of game media during the game, the inclination angle gradually changes.
For this reason, in the game hall, the inclination angle of the nail 10 is measured to check whether or not they maintain the initial state.

The confirmation (measurement / adjustment) of the inclination angle of the nail 10 has been performed by experts (so-called nails), hall employees, etc., relying on their own experience and sense. This required certain skills, and it took considerable time and experience to cultivate it.
Therefore, various instruments and methods that can easily measure the inclination angle of the obstacle member have been proposed in the past without requiring much experience.
For example, as a technique for mechanically measuring the inclination angle of the obstacle member, there is the following.
A measuring instrument (measuring gauge) having a plate-like main body and two legs, wherein one side of one leg is formed with a predetermined angle with respect to the axial direction of the leg. Depending on whether or not one side surface of the leg portion is in contact with the side surface of the obstacle member without a gap when the tips of the two leg portions are brought into contact with the board surface of the gaming machine, respectively, the obstacle member Is determined to determine whether or not the angle is the predetermined angle (see, for example, Patent Document 1).

As another technique, the movable member has a movable member formed with a surface (abutting surface) to be brought into contact with the side surface of the obstacle member, and a scale plate placed on the board surface of the gaming machine. There is a technique in which the contact surface is brought into contact with the side surface of the obstacle member and the displacement (degree of inclination) of the movable member is measured as the angle of the obstacle member (for example, see Patent Documents 2 to 4).
Furthermore, as another technique, it consists of a support plate that spans the left and right direction of the game board, and an angle measurement device body that is placed on this support plate, and moves the angle measurement device body in the vertical and horizontal directions. In addition, there is one that measures the inclination angle of the nail by rotating the angle measuring device main body in the inclination direction of the nail (see, for example, Patent Document 5).

In addition, as a technique for measuring the angle of the obstacle member using an image, there are the following techniques.
The camera is moved so that the axial direction of the obstacle member and the optical axis direction of the camera coincide with each other, and the image of the obstacle member photographed by this camera is displayed as an image. Based on the position of the camera at the coincidence, Some measure the angle (see, for example, Patent Document 6).

  However, conventional techniques (the above-mentioned patent documents 1 to 4) for measuring a tilt angle of an obstacle member (nail) on the board surface by placing a scale plate or the like on the board surface of the gaming machine are the attackers arranged on the board surface. , Scales, etc. may not be able to be placed on the board depending on the role, winning hole, windmill, guide, production parts, liquid crystal display, etc. That is, there are cases where measurement cannot be performed freely, and in such a case, there is a problem that the reliability of measurement is lowered. In particular, the most important life nail is close to the starting chucker and the object, and it is difficult to measure despite the fact that the horizontal and vertical inclination of the life nail has a large impact on the profit of the pachinko machine. There was a problem that there was a case.

  In addition, the technique described in Patent Document 5 or 6 is based on a game board of a gaming machine, and there is a problem that a support member that supports the angle measuring device main body is enlarged. Furthermore, in order to measure, there is a problem that it is necessary to remove the game board from the gaming machine, and the measurement cannot be easily performed.

The measurement means includes a base that contacts a plurality of the obstacle members, and the inclination angle measurement means measures an inclination angle of the obstacle member with respect to a virtual reference plane set by the base.
In this way, the obstacle member (nail) approaches the obstacle (for example, an attacker, an accessory, a winning opening, a windmill, a guide member, a production component, a liquid crystal display device, etc.) disposed on the board surface of the gaming machine. Even in such a case, the virtual reference plane can be set easily, and the tilt angle can be measured easily and accurately.

Moreover, the obstruction member inclination measuring apparatus of this invention is set as the structure which used the said base as the transparent flat plate member.
In this way, since the state of the obstacle member and the like on the back side of the base portion can be visually observed, the inclination angle measuring means can be easily aligned with the obstacle member for measuring the inclination angle, and workability is improved. Can be improved.

[First embodiment]
FIG. 1 is a schematic view of an obstacle member inclination measuring apparatus according to a first embodiment of the present invention, in which (a) shows a longitudinal sectional view and (b) shows an AA sectional view.
In the figure, an obstacle member inclination measuring apparatus 1 includes a flat base plate (base) 2 placed on a virtual reference plane 200 formed by a plurality of nails 10 disposed on a board surface 110 of a pachinko machine 100; The base plate 2 includes an inclination angle measuring means 3 for measuring the inclination angle of the nail 10.
In this embodiment, the gaming machine is the pachinko machine 100, but is not limited to this, and may be an arrangement ball machine or a sparrow ball machine, for example. Further, the obstacle member is the nail 10 used in the pachinko machine 100, but is not limited thereto.

(Base plate)
The base plate 2 is a flat plate of a size that covers the plurality of nails 10 on the board surface 110, and is substantially rectangular in this embodiment. In this way, the virtual reference plane 200 is set by the base plate 2 in contact with the tops of the plurality of nails 10, and the base plate 2 can be freely moved so as to trace the tops of the nails 10, Measurement work can be performed efficiently. In addition, the base plate 2 is made of a transparent acrylic resin, and the state of the board surface 110 on the back side of the base plate 2 can be visually observed. Therefore, the base plate 2 can be moved smoothly and workability can be improved. Can do.
In the present embodiment, the base plate 2 has a substantially rectangular shape, but is not limited to this shape, and may be any shape that can be stably placed on the virtual reference plane 200.

  Here, preferably, as shown in FIG. 2, an extension base plate 4 that is detachably attached to the base plate 2 is attached. The extended base plate 4 is a substantially hexagonal flat plate, and is connected to the base plate 2 by screws 42 so that the mounting surface 41 is flush with the back surface 21 of the base plate 2. In this way, even if the plurality of nails 10 on which the base plate 2 is placed are not provided around the nail 10 (for example, the life nail 11) to be measured by providing the game component 130. The virtual reference plane 200 can be set using the nail 10 at a remote location, and the inclination angle of the life nail 11 can be measured without hindrance.

(Virtual reference plane)
The virtual reference plane 200 is a plane that is virtually set by the base plate 2 that is in contact with the uppermost portions of the plurality of nails 10 disposed on the board surface 110.
By the way, since the nail 10 of the pachinko machine 100 is automatically driven by a dedicated nailing machine, the accuracy of the height is very excellent. In general, since the accuracy of the height falls within an error of several commas, the maximum inclination angle of the virtual reference plane 200 with respect to the board surface 110 can be ignored in consideration of the diameter of the board surface 110 being about 350 mm. It is so small that it can be tolerated as a measurement error. That is, the virtual reference plane 200 can be used as the reference plane of the tilt angle measuring means 3.

(Inclination angle measuring means)
The tilt angle measuring means 3 is a means that is rotatably attached to one end of the base plate 2 and mechanically measures the tilt angle of the nail 10, and includes a rotary seat 31, a probe 32, a rotating shaft 33, and a twist. A spring 34, a gauge cylinder 35, a grooved pin 36 and a screw ring 37 are included.
In this embodiment, the tilt angle measuring means 3 using the mechanical direct contact method is used. However, the tilt angle measuring means 3 used in the present invention is not limited to this method, and various Various types of tilt angle measuring means 3 can be used. Moreover, you may digitally display the inclination state and inclination angle of the nail 10 using an electronic technique or an electric technique.

<Rotating seat>
The rotary seat 31 has a substantially disk shape with a large plate thickness, and has an annular convex portion 311 protruding from the lower side surface. The rotary seat 31 is inserted into the base plate 2 in a state where the convex portion 311 is placed on the stepped portion 22 of the base plate 2, and an annular screw ring 37 having an external thread formed on the outer peripheral surface is provided with the base plate 2. 2, the convex portion 311 is locked from above by the screw ring 37. In this way, the tilt angle measuring means 3 can be rotatably attached to the base plate 2, and the measuring direction of the tilt angle measuring means 3 can be easily adjusted according to the tilt direction of the nail 10, for example. Work efficiency can be improved.
In addition, since the measurement direction of the inclination angle measuring means 3 can be set arbitrarily, the horizontal inclination angle or the vertical inclination angle of the life nail 11 can be measured.

The rotary seat 31 has a groove-type pin 36 projecting substantially at the center of the lower surface, in which both end portions of the horizontal pin material are bent straight upward. The grooved pin 36 is provided such that the central fixing portion 361 is located at substantially the same height as the portion of the nail 10 near the bottom surface of the head 12.
The rotating seat 31 is provided with a probe 32, a rotating shaft 33, and a torsion spring 34 so as to face the fixed portion 361 of the grooved pin 36. The probe 32 is pivotally supported by a rotation shaft 33 while being urged clockwise by a torsion spring 34.

Here, preferably, the material of the rotary seat 31 may be a transparent acrylic material, and in this way, the life nail 11 whose inclination angle is to be measured can be visually observed from above, and therefore the obstacle member inclination measuring device. 1 can be easily aligned, and the measurement operation can be performed easily and accurately.
In addition, since the life nail 11 can be visually observed from above also by providing a peep hole (not shown) in the rotary seat 31, when the peep hole is provided, the material of the rotary seat 31 is the above material. It is not limited.

<Probe>
The probe 32 has a substantially rectangular bar shape, and the upper part of the rotating shaft 33 is narrowed like a needle when viewed from the side, and the lower end of the rotating shaft 33 is bent toward the groove pin 36 side. 321 is formed. The measuring unit 321 is provided so as to be located at substantially the same height as a portion near the board surface 110 of the pachinko machine 100. In this way, the fixing part 361 of the groove pin 36 abuts on the substantially uppermost part of the life nail 11 and the measurement part 321 abuts on the almost lowermost part of the life nail 11, so that the inclination angle of the life nail 11 is more accurate. It can be measured well.

<Gauge tube>
As shown in FIG. 3, the gauge cylinder 35 includes a scale plate 351 and a cylinder 352 formed integrally with the upper end face of the scale plate 351, and the lower part of the cylinder 352 is the upper part of the rotary seat 31. Is charged. The scale plate 351 is made of a transparent acrylic plate, and a scale 353 for displaying the inclination angle of the life nail 11 according to the position of the tip of the probe 32 is printed. That is, the inclination angle measuring means 3 can display the inclination angle of the life nail 11 on the scale plate 351 when the fixing part 361 and the measurement part 321 come into contact with the life nail 11.
The tilt angle measuring means 3 is configured to read the tilt angle by visual observation using display means including the probe 32 and the scale 353, but is not limited to this configuration. Although not shown, for example, as in a digital caliper, the tilt angle of the probe 32 is converted into an electrical signal, the storage means for recording the electrical signal, and the stored electrical signal is converted into the tilt angle and displayed. It is good also as a structure provided with the display means.

Next, a method of using the obstacle member inclination measuring apparatus 1 having the above configuration will be described with reference to the drawings.
In the obstacle member inclination measuring apparatus 1, the base plate 2 is in contact with the plurality of nails 10 such that the nail 10 (for example, the life nail 11) whose inclination angle is measured is positioned at the approximate center of the inclination angle measuring means 3. Is done. Thereby, the base plate 2 sets the virtual reference plane 200. That is, the base plate 2 is placed on the virtual reference plane 200 based on the plurality of nails 10.
The above state can be easily executed by the measurer holding the base plate 2 with the left hand.

Next, the inclination angle measuring means 3 is rotated so that the measurement direction of the inclination angle and the fixing portion 361 of the groove pin 36 are orthogonal to each other.
Usually, there are three measurement directions of the inclination angle, and the first is a case where the maximum inclination angle of the life nail 11 is measured, and the measurer can make the inclination direction recognized visually and the fixing portion 361 orthogonal to each other. The tilt angle measuring means 3 is rotated.
The second is a case where the horizontal inclination angle of the life nail 11 is measured, and the measurer rotates the inclination angle measuring means 3 so that the horizontal direction recognized by visual observation and the fixing portion 361 are orthogonal to each other.
The third is a case where the vertical inclination angle of the life nail 11 is measured, and the measurer rotates the inclination angle measuring means 3 so that the vertical direction recognized by visual observation and the fixing portion 361 are orthogonal to each other.

Next, the measurer moves the tilt angle measuring means 3 in the measurement direction until the fixing portion 361 contacts the life nail 11 while the base plate 2 is in contact with the nail 10. Usually, the measuring part 321 of the probe 32 comes into contact with the life nail 11 before the fixing part 361, and then the fixing part 361 comes into contact with the life nail 11. At this time, the measurer can measure the inclination angle of the life nail 11 by reading the position of the probe 32 on the scale 353. In addition, since the lower surface of the rotary seat 31 is located above the rear surface 21 of the base plate 2 or on the same surface as the rear surface 21, the base plate 2 can be smoothly moved along the virtual reference plane 200. .
Here, the measurement unit 321 and the fixing unit 361 are moved in the measurement direction until they come into contact with the life nail 11, but this movement is an extremely simple operation of moving the base plate 2 by a minute distance while contacting the nail 10. Yes, the workability of measurement work can be greatly improved. Further, since the base plate 2 stably moves on the virtual reference plane 200, no measurement error due to human error occurs, and the measurement accuracy of the tilt angle can be improved.

  As described above, according to the obstacle member inclination measuring apparatus 1 of the present embodiment, the nail 10 (for example, the life nail 11) for measuring the inclination angle is disposed on the board surface 110 of the pachinko machine 100 (for example, the obstacle) The virtual reference plane 200 can be easily set and tilted easily and accurately even when close to an attacker, an accessory, a prize opening, a windmill, a guide member, a production component, a liquid crystal display device, etc. The angle can be measured.

In addition, the structure of the base plate 2 is not limited to the said embodiment, For example, as shown in FIG. 4, it is good also as the base plate 2a which consists of a large hex-shaped flat plate.
The base plate 2a is provided with a plurality of mounting holes 23 corresponding to important nails 10 (not shown) driven in the vicinity of each prize-winning port or windmill of the pachinko machine 100. The mounting holes 23 are formed with stepped portions 22, and the convex portions 311 a of the rotary seat 31 of the inclination angle measuring means 3 are placed on the stepped portions 22. Further, since the screw ring 37 is not used, the tilt angle measuring means 3 is detachably inserted into the mounting hole 23. That is, with the base plate 2a being in contact with the plurality of nails 10 on the board surface 110, the inclination angle measuring means 3 is sequentially inserted into the mounting holes 23 corresponding to the important nails 10 to be measured, and measurement is performed. The inclination angle of the plurality of nails 10 can be measured efficiently.

[Second Embodiment]
FIG. 5: has shown the structure schematic of the obstruction member inclination measuring apparatus concerning 2nd embodiment of this invention.
In the figure, the obstacle member inclination measuring apparatus 1b is different from the first embodiment in that an optical non-contact type inclination angle measuring means 5 is provided instead of the inclination angle measuring means 3. Other components are the same as those in the first embodiment.
Therefore, in FIG. 5, the same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
As the start port 132, a guide 1321, tulip 1322 and a start port main body 1323 are arranged from above.

(Inclination angle measuring means)
The tilt angle measuring means 5 includes an optical means 51, an imaging system 52, an imaging means 53, and a main body housing 54.
Here, the optical means 51 is a member that contacts or approaches the life nail 11 when measuring the inclination angle of the life nail 11, that is, a member that is disposed at a position closest to the life nail 11. In a state where the optical means 51 approaches the life nail 11, each image of a plurality of measurement portions on the life nail 11 is formed by the imaging system 52.
Note that the reference surface of the obstacle member inclination measuring apparatus 1b uses the virtual reference surface 200 as in the first embodiment, so that the front end surface 513 of the optical means 51 is usually separated from the board surface 110.

As shown in FIG. 6, the optical means 51 has an upper surface front portion 5111, an upper surface rear portion 5112, and an upper surface inclined portion 5113 sandwiched therebetween, and the upper surface front portion 5111 is an upper surface rear portion. It is formed to be one step lower than 5112. The lower surface 512 includes a lower surface front portion 5121, a lower surface rear portion 5122, and a lower surface inclined portion 5123 sandwiched therebetween, and the lower surface front portion 5121 is formed to be one step higher than the lower surface rear portion 5122. ing.
By adopting such a shape, the area of the front end surface 513 of the optical means 51 is reduced, so that the optical means 51 can be inserted into a narrow area between the opposing life nails 11.

Further, as shown in the figure, in the optical means 51, the right side surface 514 has a right side front portion (body portion proximity portion) 5141, a right side rear portion (head portion proximity portion) 5142, and a right side surface sandwiched between them. The right side rear part 5142 is formed at a position deeper than the right side front part 5141 by a step part (step part) 5143. Further, the left side surface 515 includes a left side front portion (body portion proximity portion) 5151, a left side rear portion (head proximity portion) 5152, and a left side step portion (step portion) 5153 sandwiched therebetween. The left side rear part 5152 is formed at a position deeper than the left side front part 5151.
And the right side level | step difference 5143 and the left side level | step difference 5153 have the distance from the front end surface 513 shorter than the length of the trunk | drum 13 of the life nail 11, respectively.

  By adopting such a shape, the left side rear part 5152 or the right side rear part 5142 of the optical means 51 is prevented from coming into contact with the head 12 of the life nail 11, while the left side front part 5151 or the right side front part. In 5141, the body part 13 of the life nail 11 can be brought into contact or approached. Thereby, the image of the some measurement part in the trunk | drum 13 of the life nail 11 can be caught clearly.

Further, as shown in FIG. 7, the optical unit 51 includes a transmission member 516 and a reflection member 517.
The transmission member 516 is a member in which a measurement line is formed, and can be formed of, for example, glass or acrylic.
The transmission member 516 can be formed in a plate shape having a predetermined thickness, and the optical means 51 can have a laminated structure in which a plurality of the plate-like transmission members 516 are stacked.

The transmission member 516 is formed with measurement lines that respectively pass through two or more measurement portions of one life nail 11.
For example, as shown in FIG. 7, when the transmission member 516 comes into contact with or approaches the left life nail 11a, the measurement lines (first measurement line L1, second measurement line) that respectively pass through two measurement portions of the life nail 11a. A measurement line L2) is formed. Further, when the transmitting member 516 comes into contact with or approaches the right life nail 11b, measurement lines (third measurement line L3 and fourth measurement line L4) passing through the two measurement portions of the life nail 11b are formed. The

By the way, among the measurement parts P of the life nail 11 through which the measurement line L passes, the first measurement part P1 is, for example, a part close to the bottom surface of the head 12a in the left life nail 11a, and the second measurement part P2 is the left measurement nail. It can be a part close to the board surface 110 in the life nail 11a. In particular, the first measurement portion P1 can be a portion closer to the bottom surface of the head 12a than a portion with which a game medium (for example, a pachinko ball or the like) abuts.
Specifically, as shown in FIG. 7, the first measurement portion P <b> 1 can be a portion separated from the bottom surface of the head 12 of the life nail 11 by about 1.5 [mm]. On the other hand, the 2nd measurement part P2 can be made into the part about 1.0 [mm] away from the board surface 110 among the trunk | drum 13a of the life nail 11a. The part where the pachinko ball comes into contact with the life nail 11a is usually a part away from the board surface 110 by about 5.5 [mm].
In this way, by providing the measurement portions at positions apart from each other in one life nail 11a, the difference (displacement) in the images of these measurement portions becomes clearer, so the inclination angle of the life nail 11a can be further increased. It can be measured accurately.

It should be noted that the surface of the portion of the transmission member 516 where the measurement line is not formed can be shielded for light shielding.
Moreover, in FIG. 7, although the two measurement parts in one life nail 11a are two, it is not restricted to two, It can also be set three or more.
Furthermore, in the present embodiment, the first optical means 51a and the second optical means 51b are provided to measure the pair of life nails 11a and 11b at the same time, but it is also possible to measure either one of them. Of course.

One or more reflection members (optical distance adjustment members) 517 are provided in one optical means 51, and each measurement line (in FIG. 7, the first measurement line L1, the second measurement line L2, and the third measurement line). The optical distances of the line L3 and the fourth measurement line L4, or all the measurement lines from the first measurement line L1 to the fourth measurement line L4) are all arranged to be the same. In this way, by making the optical distances of the respective measurement lines the same, their focal lengths coincide and a clear image can be obtained.
The reflecting member 517 also has a function of increasing the strength of the optical means 51.

The imaging system 52 is composed of a plurality of optical elements and forms images of two or more measurement portions in each of the plurality of life nails 11a and 11b.
Specifically, as shown in FIG. 5, the imaging system 52 includes an objective lens group 521, an eyepiece lens 522, a prism 523, and an eyepiece lens 524 for imaging means.

The objective lens group 521 is a lens group provided on the optical means 51 side in the main body casing 54. In FIG. 5, one lens is provided as the objective lens group 521. However, the objective lens group 521 is not limited to one lens, and a plurality of lenses may be provided.
The eyepiece lens 522 is a lens disposed at a position where the eye of the measurer approaches. When the eyepiece 522 is visually observed, an image formed by the imaging system 52 (an image showing two or more measurement portions of the pair of life nails 11a and 11b) is about 25 [cm] as a virtual image (not shown). ] It looks ahead. A real image is created between the eyepiece lens 522 and the prism 523 or on the imaging means 53.

A specific example of an image visually recognized from the eyepiece lens 522 is shown in FIG.
For example, the optical means 51 has a structure as shown in FIG. 7 (a structure in which six plate-shaped transmission members 516 having a predetermined thickness are bonded together, and four of them are joined to the main body housing 54). If so, as shown in FIG. 8, a plurality of measurement parts (a first measurement part P1, a second measurement part P2, a third measurement part P3 in FIG. 7) of the plurality of life nails 11a and 11b. , The fourth measurement portion P4) appears side by side in the horizontal direction of FIG.

Each image of the plurality of measurement parts visually recognized from the eyepiece 522 appears with the same inclination when the life nail 11a, 11b itself is inclined. And each image of two measurement parts (for example, the 1st measurement part P1 and the 2nd measurement part P2 in the left life nail 11a) in one life nail 11 when life nail 11a itself inclines A difference δ (deviation) occurs between the images of the two measurement portions. By looking at this difference δ, the inclination angle of the life nail 11a can be known.
In order to know the inclination angle of the life nail 11, a transparent plate (scale plate) on which a grid (mesh), a scale, an angle, a crosshair, and the like are applied can be provided on the outer side of the eyepiece lens 522.

The prism 523 is an optical element for sending an image to both the eyepiece lens 522 and the imaging means eyepiece lens 524.
In FIG. 5, three lenses and one prism are used as the imaging system 52. However, the present invention is not limited to three lenses and one prism, but has a suitable shape and function. An optimum number of optical elements can be used in combination.
In the present embodiment, “optical means 51” and “imaging system 52” are collectively referred to as “optical system”.

  The imaging means (signal conversion means) 53 can be constituted by, for example, a CCD (Charged Coupled Device) or the like, and replaces an image from the imaging system 52 with an electrical signal and outputs it to the outside (for example, a display device).

Here, although not shown, the display device may be provided.
The display device (image display means) can be constituted by, for example, a PDA (Personal Digital (Data) Assistant) or the like, receives an electrical signal sent from the imaging means 53, and based on this electrical signal, as shown in FIG. It is also possible to display various images and predetermined data.
As predetermined data, as shown in FIG. 8, the life nails 11a and 11b (indications such as “L1-L2” and “L3-L4”) to be measured, and the inclination direction of the life nails 11a and 11b (if upward) In this case, the inclination angle (for example, “0.4 [°]”) of the life nail 11a, 11b can be displayed.
Further, “unknown” can be displayed on the image when the tilt angle cannot be measured.

  The obstacle member inclination measuring apparatus 1b of the present embodiment includes two optical means 51 (first optical means 51a and second optical means 51b), so that the inclination angles of the two life nails 11a and 11b can be reduced with little effort. Measurement is possible. For example, when measuring the inclination angle of the right life nail 1111b among the two life nails 11a and 11b provided side by side, the optical means 51 is brought closer to the trunk 13b of the right life nail 11b, When measuring the inclination angle of the left life nail 11a, the optical means 51 is brought closer to the body 13a of the left life nail 11a. For this reason, when measuring the inclination angle of the right life nail 11b, the optical means 51 is located away from the left life nail 11b, and the inclination angle of the left life nail 11a is measured. In some cases, the optical means 51 is located away from the right life nail 11b. Then, the images of the life nail 11a and 11b shown in FIG. 7 appear clearly for the life nail 11a approached by the optical means 51, but become unclear for the life nail 11b separated from the optical means 51. In this case, since the inclination angle of the life nail 11b that is unclear cannot be measured accurately, "Unknown" is displayed on the image of FIG.

Moreover, you may provide an analysis part (not shown) in the obstruction member inclination measuring apparatus 1b. This analysis unit calculates the inclination angle of the life nail 11 based on the image as shown in FIG. 8 and the electrical signal sent from the imaging means 53.
Specifically, it can be performed by the following method.
As a premise, the length of the trunk 13 of the life nail 11a is about 16.0 [mm] as shown in FIG.
The measurement parts in the life nail 11a are a first measurement part P1 and a second measurement part P2.
Among these, the 1st measurement part P1 is taken as the part about 1.5 [mm] apart from the bottom face of the head 12a in the trunk | drum 13a of the left life nail 11a. On the other hand, the second measurement portion P2 is a portion separated from the board surface 110 of the gaming machine 100 by about 1.0 [mm]. In this case, the length Lp from the first measurement portion P1 to the second measurement portion P2 is
Lp = 16−1.5−1.0 = 13.5 [mm] (Formula 1)
It becomes.

In the above image, the shadow of the first measurement portion P1 of the life nail 11 included in the image displayed on the first measurement line L1 of the image and the life nail included in the image displayed on the second measurement line L2. 11 is assumed to be approximately 1.0 [mm] on the display screen (see FIG. 8).
Since this difference δ is a difference δ on the screen, the difference δ ′ between the first measurement portion P1 and the second measurement portion P2 in the actual life nail 11a (a line extending in a direction perpendicular to the virtual reference plane 200). The distance between the reference line and the first measurement portion P1 when the line passing through the second measurement portion P2 is used as a reference is obtained by the following equation when the display magnification is 10 times.
δ ′ = difference on screen δ / display magnification = about 1.0 [mm] / 10 [times] = about 0.1 [mm] (Formula 2)
The inclination angle θ of the life nail 11a can be obtained by the following calculation.
tan θ = (δ ′ / Lp) = (0.1 / 13.5) (Equation 3)
θ = 0.4244 [°] (Formula 4)
Thereby, it can be seen that the life nail 11 is inclined about 0.4 [°] upward with respect to a line (reference line) extending vertically from the virtual reference plane 200.

However, the obstacle member inclination measuring apparatus according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention.
