Abstract

PROBLEM TO BE SOLVED: To provide a technique for measuring an inclination angle of a board surface of a game machine even for a part where is no nail on the board surface of the game machine.SOLUTION: An inclinometer 10 comprises an upper installation support leg 30 and a lower installation support leg 40 which are connected to an inclinometer main body 11. An angle of inclination of a board surface is to be measured by putting the upper installation support leg 30 against the board surface while the lower installation support leg 40 which is also in contact with the board surface has moved below the upper installation support leg 30 due to gravity applied to the inclinometer 10. For a part where is no nail, a fixture object is temporarily fixed on the board surface. In this state, by making the upper installation support leg 30 engage with the fixture object, the angle of inclination of the board surface is to be measured. The inclinometer 10 comprises a linear body 110 which extends upward from the inclinometer main body 11. By fixing an end of the linear body 110 at a predetermined place of a game machine or a game island, it is possible to prevent an excessive load from being applied to the fixture object via the upper installation support leg 30.

Description

  The present invention relates to an inclinometer used for measuring the vertical of a pachinko gaming machine or measuring an inclination angle from the vertical.

  In a pachinko gaming machine (in the present application, a pachinko gaming machine may be simply referred to as a “gaming machine”), it is known that the amount of balls can be adjusted by giving an appropriate inclination to the board surface. By changing the installation angle of the board surface of the pachinko machine, the falling speed of the ball and the angle of the object fitted on the board surface change, how to play the nail of the ball moving on the board surface, how to pass the object It uses the change of. By attaching an appropriate inclination to the board surface of the gaming machine when attaching a pachinko machine, or by adjusting the inclination angle afterwards, the same effect as when adjusting the nail can be obtained more easily. Can be adjusted.

  In consideration of such points, the inventors have disclosed JP-A 63-226385, JP-A 63-226386, JP-A 10-80563, JP-A 2002-062131, JP-A 2011-115288, and the like. Have applied for. These relate to a device for fixing a pachinko gaming machine to a pachinko gaming machine installation unit (for example, a facility generally called “island”) with a variable inclination angle.

Each of these devices is useful, but when using these devices, it will be necessary to check the vertical position of the pachinko machine and check the inclination angle, and the accuracy of measurement is also required. Will be.
In view of such circumstances, an inclinometer, which is a device for measuring the inclination angle of a board surface of a pachinko gaming machine, has been conventionally proposed. The applicant of the present application has also proposed, for example, an inclinometer disclosed in Japanese Patent Application Laid-Open No. 2009-195564.

The above-mentioned inclinometer proposed by the applicant has the following structure in general terms. That is, this inclinometer has a plurality of substantially rod-shaped installation legs whose tips are brought into contact with the board surface of the gaming machine during use, and an inclinometer body to which the base ends of the plurality of installation legs are fixed. And an inclination angle measuring means provided on the inclinometer body for measuring an angle with respect to a virtual vertical axis.
The plurality of installation legs described above are longer in length than the nail erected on the board surface of the gaming machine, so that the inclinometer body can avoid interference with the nail. In addition, one of the above-described installation legs is scheduled to be brought into contact with the board surface of the gaming machine at a position higher than the other installation legs when in use, and at that time, the installation leg is a game. It is fixed or locked to one nail standing on the surface of the machine. At the time of use, the installation leg that is supposed to be in contact with the board surface of the gaming machine at a position higher than the other installation leg is fixed or locked to one nail, and the other installation leg When the tip is brought into contact with the board surface, the inclinometer body of the inclinometer is stabilized at a certain position by gravity. In that state, the tilt angle measuring means is such that the orientation of the inclinometer body on which it is provided always satisfies a certain condition due to gravity, so the tilt angle from the vertical direction of the board surface of the gaming machine is accurately determined. Can be measured.

However, it cannot be said that the inclinometer as described above has no point to be improved.
As described above, the inclinometer described above has an installation leg that is scheduled to come into contact with the board surface of the gaming machine at a position higher than the other installation legs when used. However, this means that the tilt angle of the board surface of the gaming machine cannot be measured if there is no nail that fixes or locks the installation leg if it is turned upside down.

For example, there are many recent gaming machines in which nails are not erected on the right side of the board surface. Therefore, in such a gaming machine, the inclination angle cannot be measured for the right half of the board surface.
If the inclination angle of the board surface of the gaming machine is the same in any part of the board surface, it is sufficient if only the inclination angle on the left side of the board surface of the gaming machine can be measured, but this is not the case. The rigidity of the gaming machine is not extremely high, and it is often the case that the inclination angle differs between the right side and the left side of the gaming machine (or the right side and the left side of the gaming machine board surface).
As described above, since the inclination angle of the board surface of the gaming machine affects the result of the adjustment of the ball, the inclination angle of the gaming machine board surface can be measured at any part of the gaming machine board surface. Naturally, it is preferable.

  This invention makes it the subject to provide the technique which enables the inclination angle of the board surface of a gaming machine to be measured also in the part where the nail of the board surface of a gaming machine does not exist.

The inventor of the present application proposes the following invention in order to solve the above-described problems.
The inventor of the present application proposes an inclinometer for measuring an inclination angle of a board surface of a gaming machine in which at least one nail is driven substantially perpendicular to the board surface. A plurality of substantially rod-shaped installation legs that are brought into contact with the distal ends thereof and base ends of the plurality of installation legs are connected, and the distal ends of the plurality of installation legs are brought into contact with the board surface. Measuring a tilt angle of a virtual axis that is a virtual axis having a fixed positional relationship with the inclinometer body, and a tiltmeter body configured to be fixedly determined with respect to the distance to the board surface, An inclination angle measuring means provided in the inclinometer body, and one of the installation legs is scheduled to be used at a higher position than the other installation legs when used. Of the nail There is a fixed or locking can thus criteria established leg to that of using an inclinometer, a method for measuring the tilt angle of the board of the gaming machine.
And in the method of measuring the inclination angle of the board surface of the gaming machine of the present application, when trying to measure the inclination angle of the board surface in the portion where the nail is present in the portion where the reference installation leg is to be contacted, The reference installation leg is fixed or locked to an arbitrary nail, the other installation legs are brought into contact with the panel surface, and the inclinometer is stabilized by gravity, whereby the inclinometer body with respect to the reference installation leg In a state where the orientation of the board is uniquely determined, the inclination angle of the board surface is measured by the inclination angle measuring means, and the inclination angle of the board surface is measured in a portion where the nail does not exist in the portion where the reference installation leg is to be contacted. When attempting to do so, the lower surface of the reference installation leg is locked to the upper surface of a predetermined fixed object removably attached to the panel surface, and the tip of the reference installation leg is brought into contact with the panel surface. And other installation legs The tilt angle of the panel surface is measured by the tilt angle measuring means in a state in which the tilt meter body is uniquely determined with respect to the reference installation leg by abutting the surface and stabilizing the tilt meter with gravity. To do.
That is, the inclinometer used in the method for measuring the inclination angle of the board surface of the gaming machine proposed by the present inventor may be the same as the conventional one.
In particular, the method of measuring the inclination angle of the board surface when measuring the inclination angle of the board surface in the part where the nail is present in the part where the reference installation leg is to be contacted is not different from the conventional method. On the other hand, if it is difficult to measure with a conventional inclinometer, it is possible to detach from the panel surface when measuring the inclination angle of the panel surface in the part where the nail does not exist in the part where the reference installation leg is to be contacted A predetermined fixed object is attached to the upper surface of the fixed object, the lower surface of the reference installation leg is locked to the upper surface of the fixed object, and the tip of the reference installation leg is brought into contact with the panel surface. Then, the tilt angle of the panel surface is measured by the tilt angle measuring means in a state where the orientation of the tilt meter body with respect to the reference installation leg is uniquely determined by stabilizing the tilt meter with gravity.
That is, in the method of the present application, in the case of measuring the inclination angle of the board surface in the part where the nail is not present in the part where the reference installation leg is to be contacted, a fixed object that can be detached from the board surface is attached to the board surface. By using the fixed object instead of the nail, the inclination angle of the board surface of the gaming machine is measured.
Note that the fixed object may be attached to the board surface in any way. For example, the adhesion may be adhesion by an adhesive or adsorption by a suction cup. Also, if permitted by the structure of the gaming machine, it is attached to a fixed object and a magnet that originally exists on the back side of the gaming machine's board or that is temporarily arranged on the gaming machine's board, and can be adsorbed to the magnet. It is also possible to realize the above adhesion by adsorbing a magnet or a magnet and a metal that can be adsorbed with a board surface interposed therebetween.

In the method of measuring the inclination angle of the gaming machine board surface according to the present invention, as described above, an inclinometer which is not different from the conventional one can be used.
On the other hand, if the following inclinometer is used, the above-described method of measuring the inclination angle can be realized more easily. The inventor of the present application roughly proposes two inclinometers. For convenience, these will be referred to as a first inclinometer and a second inclinometer.
In addition, the below-mentioned characteristic which the 1st inclinometer has and the below-mentioned characteristic which the 2nd inclinometer has are not exclusive, and it is also possible to implement | achieve the inclinometer provided with both.

The first inclinometer is an inclinometer that measures an inclination angle of a board surface of a gaming machine in which at least one nail is driven substantially perpendicularly to the board surface, and is longer than the nail and is in contact with the board surface during use. A plurality of substantially rod-shaped installation legs that are brought into contact with the distal ends thereof and base ends of the plurality of installation legs are connected, and the distal ends of the plurality of installation legs are brought into contact with the board surface. Measuring the tilt angle of an inclinometer body whose distance to the board surface is determined to be constant and a virtual axis that is a virtual axis in a fixed positional relationship with respect to the inclinometer body, A tilt angle measuring means provided on the meter body, and a linear body whose base end side is connected to the tilt meter body and the length from the tilt meter body to the tip thereof is adjustable. Yes.
One of the installation legs is scheduled to be used at a higher position than the other installation legs during use, and is fixed to any of the nails. Or a reference installation leg adapted to be locked, and the reference installation leg is fixed or locked to an arbitrary nail, and another installation leg is brought into contact with the panel surface, and the inclinometer Is stabilized by gravity so that the inclination angle of the board surface can be measured by the inclination angle measuring means in a state where the direction of the inclinometer body with respect to the reference installation leg is uniquely determined. The lower surface of the reference installation leg is locked to the upper surface of the predetermined fixed object that is adhesively attached to the board surface so as to be lowered toward the board surface, and another installation leg is applied to the board surface. Of the linear body Fix the end to the fixed object from the reference setting leg by fixing the end to a gaming machine located above the reference setting leg or a predetermined device fixed to the gaming machine or fixed to the gaming machine While the inclinometer is stabilized by gravity while preventing the object from detaching from the board surface, the inclination angle is determined in a state where the direction of the inclinometer body with respect to the reference installation leg is uniquely determined. An inclination angle of the panel surface can be measured by a measuring means, and means for reducing a friction coefficient with respect to the upper surface of the fixed object is provided on the lower surface of the reference installation leg, and the reference installation When the means is placed on the upper surface of the fixed object, the leg of the work leg comes into contact with the disk surface by sliding the upper surface of the fixed object toward the panel surface.
The first inclinometer generally follows the configuration of the inclinometer described in the prior art. In this inclinometer, means for reducing the coefficient of friction with respect to the upper surface of the fixed object is provided on the lower surface of the installation leg serving as the reference installation leg. As a result, when the means is placed on the upper surface of the fixed object, the tip of the reference installation leg comes into contact with the disk surface by sliding the upper surface of the fixed object toward the panel surface. ing.
In the above-described method of measuring the inclination angle of the board surface of the gaming machine, when the inclination angle of the board surface in the part where the nail does not exist in the part where the reference installation leg is to be contacted, the board surface is separated. A predetermined fixed object is attached as possible, the lower surface of the reference installation leg is locked to the upper surface of the fixed object, and the tip of the reference installation leg is brought into contact with the board surface. The tip of the reference installation leg is brought into contact with the board surface in order to keep the distance from the base end of the reference installation leg to the board surface at a predetermined fixed distance. This is to make it a certain thing. To bring the tip of the reference installation leg into contact with the board surface, push the inclinometer body toward the board surface with the reference installation leg placed on a fixed object, so that the reference installation leg faces the board surface. Just push it in.
However, when the reference installation leg is pushed toward the board surface, it cannot be said that there is no possibility that the fixed object is detached from the board surface due to an excessive load applied to the fixed object.
Therefore, the inclinometer according to the first aspect of the present invention is based on the assumption that the fixed object has an inclination in which the upper surface of the fixed object is lowered toward the board surface. Means are provided for reducing the coefficient of friction with respect to the upper surface. Accordingly, the reference installation leg slides on the upper surface of the fixed object toward the board surface when the means for reducing the coefficient of friction with respect to the upper surface of the fixed object is placed on the upper surface of the fixed object. Thereby, when making the front-end | tip of a reference | standard installation leg contact | abut to a board surface, the possibility that an excessive load will be applied to a fixed object and a fixed object will detach | leave from a board surface can be made small.

The means for reducing the coefficient of friction with respect to the upper surface of the fixed object is configured to make point contact or line contact with the upper surface of the fixed object provided on the lower surface of the reference installation leg. May be. Also, the material can be selected from materials having a small friction coefficient such as resin and metal.
The material on the upper surface of the fixed object can have a small friction coefficient, and the material (for example, a plate) having a small friction coefficient can be attached to the upper surface of the fixed object.

A second inclinometer according to the present invention is an inclinometer for measuring an inclination angle of a board surface of a gaming machine in which at least one nail is driven substantially perpendicular to the board surface, and is longer than the nail and in use. A plurality of substantially rod-shaped installation legs, whose proximal ends are brought into contact with the board surface, and base ends of the plurality of installation legs are connected, and the distal ends of the plurality of installation legs are in contact with the board surface. The tilt angle of the inclinometer main body whose distance to the board surface is determined to be constant by being set, and the virtual axis that is a virtual axis having a fixed positional relationship with respect to the inclinometer main body is measured. A tilt angle measuring means provided in the inclinometer body, a linear body whose base end side is connected to the inclinometer body, and the length from the inclinometer body to the tip thereof is adjustable, It has. One of the installation legs of the inclinometer is scheduled to be used at a higher position than the other installation legs during use, and any one of the nails is used. The reference installation leg is fixed or locked to an arbitrary nail, and the other installation leg is brought into contact with the board surface. By stabilizing the inclinometer with gravity, the inclination angle measuring means can measure the inclination angle of the panel surface in a state where the orientation of the inclinometer body with respect to the reference installation leg is uniquely determined. And the lower surface of the reference installation leg is locked to the upper surface of a predetermined fixed object removably attached to the panel surface, the other installation legs are brought into contact with the panel surface, and the linear body The tip of the By fixing the game machine that is positioned, or a predetermined device fixed to the game machine, a force that causes the fixed object to be detached from the board surface from the reference installation leg is fixed. The tilt angle of the board surface can be measured by the tilt angle measuring means in a state where the orientation of the tilt meter main body with respect to the reference installation leg is uniquely determined by stabilizing the inclinometer with gravity while preventing it from being applied. It is like that.
The second inclinometer generally follows the configuration of the inclinometer described in the prior art.
The second inclinometer is greatly different from the inclinometer described in the prior art in that a linear body is provided. As described above, the second inclinometer attaches a fixed object that can be detached from the board surface to the board surface in a portion without the nail, and uses the fixed object as a substitute for the nail. The angle of inclination of the board is measured with the legs locked. By the way, since the fixed object used as a substitute for the nail is only temporarily attached to the board surface, it may be difficult to firmly adhere to the board surface. Therefore, when the reference installation leg is locked to the fixed object and the weight of the inclinometer is applied to the fixed object, the fixed object may be detached from the board surface of the gaming machine. In the inclinometer of the present application, the tip of the above-mentioned linear body is tilted by fixing it to a gaming machine located above the reference installation leg, or a predetermined device fixed to the gaming machine or fixed to the gaming machine. A certain part (for example, most) of the total weight of the meter can be borne by a game machine having a linear body, or a predetermined device fixed to the game machine or fixed to the game machine. Since the inclination angle of the board surface using the fixed object can be measured, it is possible to prevent the situation where the fixed object is detached during the measurement of the inclination angle of the board surface. Here, the tip of the linear body may be fixed to a gaming machine, or may be fixed to a predetermined device fixed to the gaming machine or fixed to the gaming machine, and the fixed object may adhere to the board surface. Since the position also changes, the linear body cannot be used for the above-mentioned purpose if the length of the linear body is constant. However, since the length of the linear body of the present invention (the length from the inclinometer main body to the tip thereof) is variable, no matter where the tip of the gaming machine is fixed, the fixed object is the surface of the board. It can be applied anywhere, as long as it is within the length range.

A gaming machine in which the linear body is positioned above the reference installation leg, or a predetermined device fixed to the gaming machine or fixed to the gaming machine, at the tip of the linear body in the second inclinometer The linear body fixing means used for fixing to may be attached. As described above, the end of the linear body is fixed to the gaming machine or a predetermined device that fixes the gaming machine or is fixed to the gaming machine. The fixing in this case may be performed by a simple method of linking the end of the linear body to the game machine or the predetermined device. However, a wire for fixing the game machine or the predetermined device to the end of the linear body may be used. If there is a solid body fixing means, it is easy to fix the linear body to a gaming machine or a predetermined device.
The linear body fixing means is, for example, a loop formed by the linear body, a metal ring fixed to the tip of the linear body, a snap hook, an L-shaped key, or when put in a predetermined gap It is a leaf spring that is deformed to be locked in the gap. A gaming machine is usually attached to an island for attaching a gaming machine in a state of being attached to a rectangular member surrounding the gaming machine called a frame, but there is generally a slight gap above the frame. When the linear body fixing means is the above-described leaf spring, it is easy to fix the linear body fixing means in the gap.

The linear body in the second inclinometer has a base end exposed from the inclinometer body, and a loop used to pull the linear body to the base end side is provided at the base end. It may be. If it does in this way, adjustment of the length of the linear body which shortens the length from the inclinometer main body of a linear body to the front-end | tip of a linear body can be performed now.
In this case, the inclinometer main body is preferably provided with means for fixing the linear body so that the linear body can be pulled toward the proximal end side but not pulled toward the distal end side unless a release operation is performed. . With such means, the length of the linear body can be easily adjusted, and the length of the linear body from the inclinometer body to the tip is extended so that excessive force is not applied to the fixed object. Can be compatible.

The installation leg of the first inclinometer or the second inclinometer is in the shape of a rod and if the length is longer than the nail (the length of the portion exposed from the board surface), it is sufficient. The installation leg of the first inclinometer or the second inclinometer may be configured to be able to move in parallel on the facing surface of the inclinometer main body facing in parallel with the board surface. If it does so, it will become easy for an installation leg to avoid a nail.
The installation leg of the first inclinometer or the second inclinometer may be higher than the height from the board surface of the partition plate provided on the board surface to determine the range in which the balls can move. . Then, the inclination angle of the board surface can be measured in a state where at least one of the installation legs and the other one of the installation legs exceed the partition plate, and the range in which the inclination angle of the board surface can be measured is widened.
The tip of the reference installation leg of the first or second inclinometer may be rounded. It may be rounded not only to the reference installation leg but also to the tip of the installation leg.

Further, the reference installation leg of the first inclinometer or the second inclinometer is adapted to apply an urging force in a direction toward the inclinometer body by an elastic body, and the urging force provided by the elastic body. A movable body configured to move in a direction away from the inclinometer body along the reference installation leg by applying an external force to resist, the movable body being provided with the movable body; When the external force is not applied with the tip of the reference installation leg being in contact with the board surface, the nail umbrella is closer to the inclinometer body than the nail umbrella, When an external force is applied, a contact surface is provided so that the nail can be moved farther from the inclinometer body than the nail umbrella of the nail, and the movable body is provided. In front of the reference installation leg In a state where the tip is in contact with the board surface near the nail, the external surface is applied to the movable body to move the contact surface farther from the inclinometer body than the nail umbrella of the nail. By locking the nail umbrella on the surface of the nail umbrella and urging the contact surface against the nail umbrella in the direction of the inclinometer body by the urging force of the elastic body, You may be able to fix to the said board surface.
In this inclinometer, when fixing the installation leg of the inclinometer to the board surface, an external force is applied with the tip of the installation leg with a movable body in contact with the vicinity of the nail on the board surface. If there is not, the contact surface of the movable body, which is closer to the inclinometer body than the nail umbrella, is positioned farther from the inclinometer body than the nail umbrella by applying external force to the movable body. And is locked to the surface of the nail umbrella on the board surface side, and the contact surface is urged toward the clinometer body by the urging force of the elastic body. By using a movable body having such an elastic body, the force with which the installation leg presses the board surface when the installation leg of the inclinometer is fixed to the board surface is always constant. For example, when holding the inclinometer by hand and pressing the installation leg against the board surface, if the force for pressing the installation leg against the board surface is excessive, the flexible board surface will be bent, resulting in In some cases, the tilt angle cannot be measured accurately. In the present invention, in measuring the inclination of the board surface by an inclinometer, the force for pressing the installation leg against the board surface can be a constant force by the elastic body, so that the above-mentioned problems can be avoided. It becomes possible to improve the accuracy of measurement when measuring the inclination angle of the board surface without using a fixed object.
Note that this inclinometer is such that the installation leg having such a movable body can be detachably fixed to the board surface. One can release his hand from the inclinometer. Thus, the operator can conveniently measure the inclination angle of the board surface while looking at the inclinometer.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a best embodiment for carrying out the invention will be described with reference to the drawings.

First, a description will be given of a general configuration of a gaming machine in which the inclination angle of the board surface is measured by an inclinometer described later according to this embodiment and an island to which the gaming machine is attached.
In FIG. 1 and FIG. 2, 300 is a gaming machine.
The gaming machine 300 includes a board surface 301 on which balls move on the surface.
A number of nails 302 are erected on the board surface 301. In the gaming machine 300 according to this embodiment, a large number of nails 302 are erected on the left side of the board surface 301, and hardly exist in the upper right part of the board surface 301.
Further, the board surface 301 is provided with a partition plate 303 for determining a range in which the balls can move on the board surface 301. The ball moves in a substantially circular range surrounded by the partition plate 303. Although not necessarily limited to this, in this embodiment, the height of the partition plate 303 from the board surface 301 (the width of the partition plate 303) is constant in all portions in the length direction.
The board surface 301 of the gaming machine 300 is usually covered with a glass door on the front of the board surface 301, but the door is not shown in FIG. 1 for simplicity. Also, below the gaming machine 300, there are generally a tray for receiving a ball made up of an upper plate and a lower plate, and a handle used for an operation for driving the ball, which is also illustrated for the same reason. Is omitted.

The gaming machine 300 is usually fixed to a structure called an island 400 in a hall. The island 400 may be made of metal, but in many cases is made of wood, and has a structure in which a large number of gaming machines 300 can be attached in parallel.
In addition to the island, ball lending machines that lend gaming balls to users, call lamps that inform users and hall clerk about the status of gaming machines, ball lending machines and gaming machines are supplied with balls, and from gaming machines A ball circulation mechanism for collecting the loose balls and circulating the balls is appropriately attached as necessary, but illustration of these is also omitted.
The gaming machine 300 is attached to the island 400 via a member called a frame 500. Although the frame 500 may be made of metal, it is usually made of wood, and has a rectangular shape with four plates as four sides. The gaming machine 300 is fixed to the island 400 by fixing the frame 500 to the island 400 while the gaming machine 300 is fixed to the front surface. Specifically, the island 400 includes a lower plate 401 on which the frame 500 is placed, and an upper plate 402 parallel to the lower plate 401 positioned on the upper side of the frame 500. The plate corresponding to the side is fixed to the lower plate 401, and the plate corresponding to the upper side is fixed to the upper plate 402 by using a suitable means such as a nail or a dedicated metal fitting, respectively, so that it is fixed to the island 400. . At that time, the board surface 301 of the gaming machine 300 is given an inclination that falls slightly backward. In some cases, the inclination angle can be changed afterwards, as already described in the background art section of the present application.
In addition, as shown in FIG. 2, a slight gap (for example, about several mm) is usually provided between the upper plate of the frame 500 and the upper plate 402.

Next, the inclinometer 10 will be described.
FIG. 3 shows the inclinometer on the back surface (for convenience, the surface facing the panel surface 301 when the inclinometer 10 is used is the front surface of the inclinometer 10 and the surface far from the panel surface 301 is the rear surface of the inclinometer. 4) is a perspective view showing a state viewed from the side, FIG. 4 is a perspective view showing a state in which a lid described later on the back side of the inclinometer 10 is removed, and FIG. It is a perspective view which shows the state which looked at the meter from the front side.

The inclinometer 10 has an inclinometer body 11 whose length direction is the up-down direction when used. The inclinometer body 11 is not limited to this, but is made of metal or resin, and is formed in a substantially rectangular parallelepiped shape. A hole 11A is formed in the upper surface of the inclinometer body 11 in this embodiment. However, the position of the hole 11A is not limited to this.
In this embodiment, the inclinometer 10 measures the inclination angle of the board surface 301 in a state where the facing surface 12, which is a front surface of the inclinometer body 11 that is a substantially rectangular parallelepiped, faces the board surface 301 in parallel.
The inclination angle of the board surface 301 from the direction perpendicular to the ground can be measured by the inclination angle of the facing surface 12. The line along the maximum inclination direction on the facing surface 12 is an example of a virtual axis in the present invention.

The inclinometer body 11 in this embodiment has a lid 13 that is a rectangular plate parallel to the facing surface 12 as described above. A hole 13A is formed in the middle of the lid 13. However, the position of the hole 13A is not limited to this.
A table-like member 14 having a surface perpendicular to the back surface of the lid 13 is attached to the lid 13. Although not shown in FIGS. 3 to 5 on the upper surface of the table-like member 14 when the inclinometer 10 is used, a plurality of level meters in a direction perpendicular to the lid 13 is used as the inclination angle measuring means of the present application. 15 is attached (FIGS. 6 and 7). When the inclinometer 10 is installed perpendicular to the ground, each level meter 15 has an end closer to the lid 13 higher than the other end, and has an inclination angle A. In this embodiment, the level gauges 15 on the table-like member 14 are installed so as to have different inclination angles A. When the inclinometer 10 is installed on the board surface 301, if there is a level meter 15 that shows horizontal, the inclination angle A of the level meter 15 coincides with the inclination angle of the opposing surface 12 from the vertical direction with respect to the ground. To do. As described above, the inclinometer body 11 is installed such that the facing surface 12 is parallel to the board surface 301. Therefore, the inclination angle A which is the inclination angle of the opposing surface 12 is an inclination angle of the board surface 301 from the vertical direction with respect to the ground. For example, in this embodiment, four level meters 15 are used, and the inclination angle A given to each level meter 15 is 3 minutes and 3.5 minutes, respectively, according to the shank method from the front of FIGS. 4 minutes and 4.5 minutes. Therefore, when the inclinometer 10 is installed on the board surface 301, for example, if the level meter 15 that measures 4 degrees is horizontal, the inclination angle of the board surface 301 is 4 degrees. The number of level meters 15 and the inclination angle of each level meter 15 can be determined appropriately. Furthermore, the level meter may not be used as the tilt angle measuring means, and the table-like member 14 may not be used depending on the tilt angle measuring means. For example, instead of the level meter 15, it is conceivable to provide a tilt angle measuring device with a display controlled by a computer that includes a tilt sensor inside the tilt meter body 11.

A substantially rod-shaped installation leg is connected to the facing surface 12 of the inclinometer body 11. For example, two installation legs 30 and 40 each having a prismatic shape are connected to the inclinometer body 11 in this embodiment. These installation legs 30 and 40 need to be longer than the nail 302. In this embodiment, the installation legs 30 and 40 are such that the opposed surface 12 and the board surface 301 are parallel to each other in a state where the tips of the installation legs 30 and 40 are in contact with the board surface 301. The distance from the board surface 301 to the board surface 301 is constant. That is, the tips of the installation legs 30 and 40 are flush with each other. The number of installation legs need not be two, and may be increased in accordance with factors such as the shape of the inclinometer body 11. In this embodiment, the installation leg has a prismatic shape, but may have another shape as long as it is substantially rod-shaped. For example, it may be a columnar shape.
Note that at least one tip of the installation legs 30 and 40 may be rounded into, for example, a hemisphere, as shown in FIGS. 14 (A) and 14 (B).

Of the two installation legs, the installation leg 30 that is relatively present at the time of use corresponds to the reference installation leg in the present application. The installation leg 30 is in a range above the position of the center of gravity of the inclinometer 10.
Although not shown in FIGS. 3 to 5, the installation leg 30 is provided with a movable body 31 (FIG. 9). The movable body 31 is for fixing the installation leg 30 and the nail 302 as described later. Of course, the installation leg 30 may be able to be fixed to the nail 302, but it is sufficient if the installation leg 30 can be locked to the nail 302. There is no particular need to provide a movable member 31 (how the movable member 31 is movable will be described later). For example, the nail 302 can be fitted into the installation leg 30 with the tip of the installation leg 30 in contact with the board surface 301, and the nail can be removed even if the hand is released from the inclinometer 10 in this state. A groove may be provided so as to maintain the locking of the installation leg 30 with respect to 302.
On the other hand, in this embodiment, the other installation leg 40 is not provided with a movable body, but both of the two installation legs 30 and 40 may be provided with a movable body.

FIG. 8 is a diagram showing an internal structure near the movable body 31 of the installation leg 30, and FIG. 9 is an enlarged view of the vicinity of the movable body 31 of the installation leg 30. A cavity 32 having a substantially rectangular cross section is present in a portion of the installation leg 30 that is covered with the movable body 31. A first spring 33 is disposed inside the cavity 32. The movable body 31 is composed of the first resin body 50 and the second resin body 60, and is configured to be combined so as to sandwich the cavity 32 therebetween. The first resin body 50 has a first protrusion 51. The first protrusion 51 has a plate shape parallel to the length direction of the installation leg 30, and the installation legs are fitted to both ends near the cavity 32 so that the first protrusion 51 can be fitted. There is a depression 34 having a length parallel to the length direction of 30. The length of the installation leg 30 of the recess 34 in the length direction is longer than the length of the first protrusion 51 in the same direction.
Further, a groove 52 is provided on the lower surface of the movable body 31. As will be described later, the groove 52 is used by fitting a nail 302 therein, and has a width and a depth so that it can be used.

  The first resin body 50 has a rectangular parallelepiped second protrusion 53, which is inserted into the cavity 32 of the installation leg 30. In this state, the front surface of the installation leg 30 of the second protrusion 53 is brought into contact with the first spring 33. The first spring 33 is already in a contracted state with the second protrusion 53 being in contact with the first spring 33, and always urges the second protrusion 53 toward the inclinometer body 11. It is like that. By moving the movable body 31 away from the inclinometer body 11 along the installation leg 30, the second protrusion 53 further contracts the first spring 33, and the second protrusion 53 is directed toward the inclinometer body 11. The power to urge you to become stronger.

  In this embodiment, the first resin bodies 50 are fitted so that the two first protrusions 51 fit in the corresponding two depressions 34 and are covered with the second resin body 60 from above. The first protrusion 51 can be moved along the recess 34 while being guided in the length direction of the installation leg 30. The first protrusion 51 can be moved only within the range of the length of the recess 34, and accordingly, the moving range of the movable body 31 is also limited.

  The surface closest to the inclinometer body 11 of the movable body 31 is the contact surface 35. The contact surface 35 moves as the movable body 31 moves. As shown in FIG. 9, the contact surface 35 can be moved from the position a to the position b when the movable body 31 is in the initial state. The position b is closer to the board surface 301 than the surface of the nail 302 on the board surface 301 side of the nail umbrella 22. As described above, when the movable body 31 is moved in the direction of the board surface 301, a strong force for biasing the movable body 31 in the direction of the inclinometer body 11 is generated by the first spring 33. When the movable body 31 is released so that the contact surface 35 contacts the surface of the nail umbrella 22 on the board surface 301 side, the movable body 31 is locked to the nail 302 by the biasing force generated in the movable body 31. be able to. At this time, the movable body 31 can be fixed in a stable state by the nail 302 by fitting the nail 302 into the groove 52. The movable body 31 does not need to be made of resin or a rectangular parallelepiped shape, but the nail umbrella 22 slides in a portion from the contact surface 35 of the movable body 31 to the lower surface of the movable body 31 having the groove 52. It is preferable that the shape of the nail 302 can be locked (for example, a shape that is not chamfered) and has sufficient rigidity.

In this embodiment, the installation leg 40 can be moved in parallel in the vertical direction on the facing surface 12 along the length direction of the inclinometer body 11.
There is no particular limitation on the configuration for allowing the installation leg 40 to be moved along the length direction of the inclinometer main body 11, but in this embodiment, for example, the configuration as shown in FIG. It has been adopted.
In this embodiment, the inclinometer body 11 is formed in a substantially rectangular parallelepiped shape as described above. On the facing surface 12 of the inclinometer body 11, there is a notch 16 having a long side in the length direction of the inclinometer body 11. The installation leg 40 is connected to the inclinometer main body 11 with its base end inserted into the opposing surface 12.
Inside the inclinometer main body 11, a fixing plate 70 for fixing the base end of the installation leg 40, and the inside of the inclinometer main body 11 together with the fixing plate 70 fitted with the fixing plate 70, are formed in the above-described notch 16. A moving table 80 that moves along is accommodated.
The fixed plate 70 has a rectangular plate portion 72 provided with a through hole 71 which is a hole passing through the fixed plate 70 at the center thereof, and an angle extending in the back direction of the clinometer main body 11 from two opposite sides of the plate portion 72. Two columnar fixing legs 73 are provided. The installation leg 40 is fixed to the fixing plate 70 by screws 90. The fixing is performed by screwing the screw 90 penetrating the above-described through hole 71 into the base end side surface of the installation leg 40. In order to make this possible, a screw hole 41 is provided in the surface of the installation leg 40 on the side of the inclinometer main body 11 so that the screw 90 can be screwed therein. The diameter of the through hole 71 is set such that the screw portion of the screw 90 passes but the screw umbrella does not pass.
The moving table 80 has a substantially rectangular parallelepiped shape. The movable table 80 is not necessarily limited to this, but is made of resin in this embodiment. Two insertion ports 81 and a cylindrical hole 82 are provided on the surface of the moving table 80 facing the fixed plate 70. The insertion port 81 is a hole whose cross-sectional shape substantially corresponds to the cross-sectional shape of the fixing leg 73, and is provided at a position corresponding to the position of the two fixing legs 73. The cylindrical hole 82 is a hole having a relatively shallow circular cross section. One end of the second spring 100 can be fitted into the cylindrical hole 82.
The fixed plate 70 includes the second spring 100 sandwiched between the movable base 80 and the two fixing legs 73 inserted into the insertion ports 81 of the movable base 80, respectively. It is stored in. In this state, the second spring 100 is in a contracted state with one end abutting against the movable table 80 and the other end abutting against the fixed plate 70. Therefore, the fixed plate 70 is always urged by the second spring 100 in the direction of the board surface 301 with a constant force. Thereby, the surface on the facing surface 12 side of the fixed plate 70 is in a state of being pressed against the inner wall of the facing surface 12 of the inclinometer body 11. In this state, it is almost impossible to move the installation leg 40 along the notch 16 by a force caused by friction between the fixed plate 70 and the inner wall of the inclinometer body 11. However, if the installation leg 40 is pushed in the direction of the moving base 80 by applying a force capable of further compressing the second spring 100 so that the fixed plate 70 does not come into contact with the inner wall of the inclinometer body 11, the installation leg 40 can be installed. The service leg 40 is easily moved. That is, with this configuration, in this embodiment, the installation leg 40 can be freely moved in the length direction of the cut 16 and the installation leg 40 can be moved to any position in the length direction of the cut 16. It is compatible with fixing with.
However, the installation leg 40 does not necessarily have to be movable, and if the movable direction is parallel to the facing surface 12, the installation leg 40 must be limited to the vertical direction along the length direction of the inclinometer body 11. There is no. Further, the installation leg 30 may be movable as long as it is in a range above the center of gravity of the inclinometer 10.

The inclinometer 10 of this embodiment also includes a linear body 110 that is a strong wire, for example. The distal end of the linear body 110 passes through the hole 11A, and the proximal end of the linear body 110 passes through the hole 13A. Thereby, the linear body 110 has penetrated the inclinometer body 11.
The linear body 110 penetrates through a cylindrical member 130 (see FIGS. 11 to 13) attached to the upper end when the inclinometer 10 inside the inclinometer body 11 is used by an appropriate method.
In a normal state, the linear body 110 is fixed to the cylindrical member 130. The linear body 110 is fixed to the inclinometer main body 11 by the fixing by the cylindrical member 130.
A loop 111 is provided on one end side of the linear body 110. A large loop 112 having a larger diameter than the loop 111 is provided on the other end side of the linear body 110. The large loop 112 is large enough to hold an arbitrary finger, but may be larger than that such as allowing several fingers to pass.
A fixing plate 120 is attached to the loop 111.
The fixed plate 120 is a metal plate. The fixed plate 120 has a leaf spring portion 121 that is folded in a mountain. The leaf spring 121 is deformed so that its thickness is reduced when compressed in the thickness direction of the fixed plate 120, and generates a force to return to the original thickness. The fixing plate 120 is also provided with a hole 122. A hook 123 is erected on the edge of the hole 122. The loop 111 of the linear body 110 is hooked on the hook 123 after passing through the hole 122. Thereby, the linear body 110 is connected to the hook 123.
For reference, the linear body 110 and the cylindrical member 130 taken out from the inclinometer 10 are shown in FIG.

The configuration of the cylindrical member 130 will be described.
FIG. 12 is an exploded view of the cylindrical member 130, and FIG. 13 is a cutaway view of the cylindrical member 130. FIG. 13 shows a state in which an outer cylinder, which will be described later, is broken by a plane passing through the shaft as a whole, and an inner cylinder, which will be described later, is broken in the same plane as the plane in the upper half of FIG. ing.

The cylinder member 130 is cylindrical. The cylinder member 130 includes an outer cylinder 131, an inner cylinder 132, a sphere 133, and an elastic spring 134.
The outer cylinder 131 is cylindrical. An inner cylinder 132 is inserted into the cylindrical outer cylinder 131. A groove 131 </ b> A is cut in the outer peripheral surface of the outer cylinder 131.
A tapered portion 131B is provided on the inner peripheral surface of the outer cylinder 131. The tapered portion 131B is tapered such that the inner diameter gradually decreases toward the front. The diameter of the inner peripheral surface of the outer cylinder 131 is constant in the portion after the tapered portion 131B at the rear end of the tapered portion 131B.
At the rear end of the inner peripheral surface of the outer cylinder 131, a locking portion 131C having a ring-shaped cross section is provided. The hole opened inside the locking portion 131C is for guiding an inner cylinder rear end portion, which will be described later, of the inner cylinder 132, and has a diameter slightly larger than the outer shape of the inner cylinder rear end portion. Yes.

The inner cylinder 132 is cylindrical. The inner cylinder 132 includes, from the front side, a cylindrical inner cylinder front end portion 132A, an inner cylinder intermediate portion 132B having a truncated cone shape, and a cylindrical inner long rear end portion 132C. The inner cylinder tip 132A projects forward from the tip of the outer cylinder 131. The rear end of the inner cylinder rear end portion 132C substantially coincides with the rear end of the outer cylinder 131 when no external force is applied to the inner cylinder 132.
The inner cylinder front end part 132A, the inner cylinder intermediate part 132B, and the inner cylinder rear end part 132C are coaxial, and the inside thereof is penetrated by a through hole 132D. In the through hole 132D, the inner cylinder intermediate part 132B has a diameter larger than that of the other part as shown in the figure, but in the other part, the linear body 110 is shifted to the front and back. The diameter is a constant diameter that is somewhat larger than the diameter of the body 110. Note that the through hole 132D may have a constant diameter in all portions.
In this embodiment, a communication hole 132E, which is a circular hole, is formed in the inner cylinder intermediate portion 132B of the inner cylinder 132 so as to communicate with the through hole 132D. A ball 133 is fitted in each of the communication holes 132E. The diameter of the sphere 133 is a distance from the linear body 110 to a predetermined portion of the tapered portion 131B of the outer cylinder 131 (although not limited thereto, in this embodiment, the middle of the tapered portion 131B in the front-rear direction). It is equal to.

  The elastic spring 134 is a general coil spring. As shown in FIG. 13, the elastic spring 134 is placed in the internal space of the outer cylinder 131 in a state of being wound around the inner cylinder rear end portion 132 </ b> C. The elastic spring 134 has a tip abutted against a donut-shaped surface formed at a portion where the inner cylinder intermediate portion 132B and the inner cylinder rear end 132C intersect, and a rear end abutted against the front surface of the locking portion 131C. . The elastic spring 134 is compressed and always applies an urging force to the inner cylinder 132 so as to push the inner cylinder 132 toward the front side.

As described above, the linear body 110 can move forward and backward relative to the cylindrical member 130. The mechanism is as follows.
The cylindrical member 130 shown in FIG. 13 is in a normal state.
In this state, the inner cylinder 132 is biased forward by the elastic spring 134. In this state in which the inner cylinder 132 is urged forward, the ball 133 peeking from the communication hole 132E provided in the inner cylinder intermediate part 132B is pushed forward and comes into contact with the tapered part 131B of the outer cylinder 131. Move in the axial direction. Then, the three spheres 133 press the linear body 110 from three directions. In this state, the linear body 110 cannot move forward even if it is pulled forward. This is because when the linear body 110 is pulled forward, the sphere 133 receiving the frictional force from the linear body 110 tends to move forward, thereby increasing the force with which the sphere 133 presses the linear body 110. Because. On the other hand, in this state, the linear body 110 can be pulled backward. When the linear body 110 is pulled backward, the ball 133 that receives the frictional force from the linear body 110 receives a backward force when the linear body 110 is pulled backward, and the inner cylinder 132 also returns to the elastic spring 134. It falls back slightly against the urging force of. Then, the diameter of the inner space of the outer cylinder 131 in that portion is larger than the diameter of the tapered portion 131B in the portion where the ball 133 is in contact with the state shown in FIG. It moves to the surface side and the pressing of the linear body 110 by the sphere 133 is released. Therefore, even in the state shown in FIG. 13, the linear body 110 can be pulled backward.
On the other hand, when the inner cylinder tip 132A of the inner cylinder 132 is pushed backward toward the outer cylinder 131, the linear body 110 can be pulled forward and backward. This is because if the inner cylinder tip 132A is lowered relative to the outer cylinder 131 against the urging force of the elastic spring 134, the pressure of the ball 133 against the linear body 110 is released. However, as described above, the linear body 110 can move rearward without pushing the inner cylinder distal end portion 132A toward the outer cylinder 131 rearward. This is only done if you want to move it forward.
That is, it can be said that the above-described cylinder member 130 restricts the moving direction of the linear body 110 only to the rear unless a specific operation of pushing the inner cylinder tip 132A rearward toward the outer cylinder 131 is performed. .

The inner cylinder front end portion 132A slightly protrudes upward from the hole 11A of the inclinometer main body 11.
The user pushes the inner cylinder tip 132A protruding from the hole 11A backward, that is, in the state shown in FIGS. 3 to 5 and the like, to the front of the linear body 110 by the cylinder member 130 by pushing downward. That is, in the state shown in FIGS. 3 to 5 and the like, the inclinometer body 11 can be moved upward.
On the other hand, in the state where the user does not push the inner cylinder tip portion 132A backward, the forward movement of the linear body 110 by the cylindrical member 130 is restricted, and instead, the linear body 110 is moved backward. Movement is allowed. In this state, the user can pull the linear body 110 backward by passing a finger through the large loop 112 or the like.

Next, a method for using the inclinometer 10 will be described.
This inclinometer 10 is used in two ways: when measuring the inclination angle of the board surface 301 of the gaming machine 300 using the nail 302 and when measuring the inclination angle of the board surface 301 of the gaming machine 300 without using the nail. There is.
First, the former will be described.

In measuring the inclination angle of the board surface 301 using the nail 302, first, the inclinometer 10 is fixed to the board surface 301. As described above, when the inclinometer 10 is fixed to the board surface 301, the tips of the installation legs 30 and 40 extending from the inclinometer 10 are brought into contact with the board surface 301.
At this time, the installation leg 30 is brought into contact with the board surface 301 while fitting an appropriate nail 302 into the groove 52 in the movable body 31 of the installation leg 30. At this time, if the other nail 302 interferes when the installation leg 40 is brought into contact with the board surface 301, the range of the notch 16 is set so that the installation leg 40 and the other nail 302 do not interfere with each other. Move up and down. Then, with the installation legs 30 and 40 being in contact with the board surface 301, the movable body 31 is moved from position a to position b, and the contact surface 35 of the movable body 31 is locked to the nail 302. When the hand is released from the movable body 31, the movable body 31 moves in the direction in which the contact surface 35 returns to the position a by the strong elastic force generated by the first spring 33 inside the movable body 31. The locking of the surface 35 to the nail 302 is automatically performed when the hand is released from the movable body 31. At this time, the force by which the installation leg 40 is pressed against the board surface 301 is a constant force due to the elastic force of the first spring 33.
In this embodiment, the inclination angle of the virtual axis of the inclinometer 10 is determined by two points where the installation legs 30 and 40 abut on the board surface 301. The tilt angle of the virtual axis is indicated by the tilt angle of the level meter 15 indicating the horizontal level among the plurality of level meters 15 installed at different angles, and the tilt angle of the board surface 301 is measured by the tilt angle. The The operator can perform necessary work such as adjustment of the tilt angle of the panel surface 301 while looking away from the tilt meter 10 while looking at the tilt angle of the panel surface 301 indicated by the inclinometer 10.

In measuring the inclination angle of the board surface 301 without using the nail 302, first, the fixed object 600 is attached to the portion where the installation leg 30 is to be locked. The fixed object 600 is attached to the board surface 301 so as to be detachable from the board surface 301. When the fixed object 600 is detached from the board surface 301, it is preferable that the board surface 301 is not affected at all. The fixed object 600 is, for example, an adhesive rubber, and the adhesion can be performed by, for example, the inherent adhesiveness of the rubber. However, the adhesion may be performed by an adhesive that ensures that the fixed object 600 can be peeled off the board surface 301, or may be achieved by adsorption using a suction cup or adsorption using magnetic force. When adhesion of the fixed object 600 to the board surface 301 is achieved using magnetic force, a substance that adsorbs to the fixed object 600 and the magnetic force is disposed on the back side of the board surface 301, and one of the fixed object 600 and the substance is magnetized. The other is a magnet or metal that adsorbs the magnet.
The fixed object 600 may have any shape, but is not limited to this, but in this embodiment, the fixed object 600 has a rectangular parallelepiped shape.
In this embodiment, the fixed object 600 is attached to an appropriate portion of the right half of the board surface 301 where the nails 302 are few. In FIG. 1 and FIG. 2, the fixed object 600 is attached to the outside of the partition plate 303 in the panel surface 301, but the fixed object 600 may be attached to the inside of the partition plate 303.
Next, the tips of the installation legs 30 and 40 extending from the inclinometer 10 are brought into contact with the board surface 301. At this time, the lower surface of the installation leg 30 is brought into contact with the upper surface of the fixed object 600. In this state, the weight of the inclinometer 10 is not applied to the fixed object 600. In this state, the tip of the linear body 110 is fixed to an appropriate location directly above the fixed object 600.
The place where the tip of the linear body 110 is fixed may be a part of the gaming machine 300, a part of the equipment attached to the gaming machine 300, or one of the island 400 and the frame 500 to which the gaming machine 300 is attached. May be part. In this embodiment, the tip of the linear body 110 is fixed by inserting the fixing plate 120 attached to the tip of the linear body 110 into the gap described above between the upper plate of the frame 500 and the upper plate 402. I do. When the fixing plate 120 is inserted into the above-described gap, the leaf spring portion 121 of the fixing plate 120 is compressed and deformed so that its thickness becomes small, but attempts to return to the original thickness. Due to the force, the fixing plate 120 is firmly fixed in the gap.
In addition, when the length of the front end side of the linear body 110 is insufficient, the user pushes the inner cylinder front end portion 132A protruding from the hole 11A rearward, and in this state, the linear body 110 is moved to the front end side. You can extend it. Naturally, the length of the rough linear body 110 may be adjusted before the tips of the installation legs 30 and 40 are brought into contact with the board surface 301.
Further, if the fixing plate 120 is not used for fixing the tip of the linear body 110, the fixing plate 120 is removed from the linear body 110 by removing the hook 123 from the loop 111, for example, using the loop 111. It is also possible to fix the tip of the linear body 110 to a part of the gaming machine 300 or the like. At that time, other metal fittings or the like can be connected to the loop 111 from which the fixing plate 120 is removed, and of course, it can be used to fix the tip of the linear body 110 to a part of the gaming machine 300 or the like.
Next, the user pulls the linear body 110 rearward by putting a finger into the large loop 112 or the like, and shortens the length of the linear body 110 on the tip side from the inclinometer main body 11. The length of the linear body 110 on the tip side of the inclinometer body 11 is such that the force applied from the installation leg 30 to the fixed object 600 is very small, or at least the fixed object 600 is not detached from the panel surface 301. To do.
From this point onward, the process is the same as when the inclination angle of the board surface 301 is measured using the nail 302. The inclination angle of the virtual axis of the inclinometer 10 is determined by the two points where the installation legs 30 and 40 abut against the board surface 301. Also in this case, the operator can perform necessary work such as adjustment of the inclination angle of the panel surface 301 while looking away from the inclinometer 10 while looking at the inclination angle of the panel surface 301 indicated by the inclinometer 10. .

<Modification>
The inclinometer 10 used in the above-described method for measuring the inclination angle of the board surface 301 includes the linear body 110, but the inclinometer 10 used in the modification does not require the linear body 110. In the inclinometer 10 of the modified example without the linear body 110, the cylindrical member 130 is naturally unnecessary.
In this modification, a sliding portion 31A is provided on the lower surface of the installation leg 30, more specifically on the lower surface of the movable body 31 (FIG. 15). The sliding portion 31A is made of a material having a smooth surface and a low coefficient of friction with a plate described later. The material is, for example, metal or resin. The lower portion of the sliding portion 31A is chamfered in a spherical shape, and by making point contact with the upper surface of the plate body described later, the upper surface of the plate body is made easier to slide.
Note that the sliding portion 31A does not necessarily need to be on the lower surface of the movable body 31 and may be directly attached to the lower surface of the installation leg 30 if structurally permitted. In addition, the sliding portion 31A is not limited to a shape that makes point contact with the plate body, for example, a shape that makes line contact with the plate body, such as a triangular prism shape whose one side in the length direction contacts the plate body. It does not matter.
The inclinometer 10 of this modification may be used in such a way that the linear body 110 does not exist and the weight of the inclinometer 10 is directly applied to the fixed object 600 described later. It is preferable that the installation legs 30 and 40 are made as light as possible, for example, made of resin.

The usage method of the inclinometer 10 by a modification is demonstrated.
In the inclinometer 10 according to the modification, as in the case of the inclinometer 10 described above, the inclination angle of the board surface 301 of the gaming machine 300 is measured using the nail 302, and the board surface 301 of the gaming machine 300 without using the nail. There are two methods of use when measuring the tilt angle of the.

  The method of measuring the tilt angle of the board surface 301 using the nail 302 is not different from the above case.

When measuring the inclination angle of the board surface 301 without using the nail 302, the fixed object 600 is attached to the portion where the installation leg 30 is to be locked, as in the case described above.
A fixed object 600 used in combination with the inclinometer 10 of this modified example includes an adhesive rubber 601 and a plate body 602. The rubber 601 is for fixing the fixed object 600 to the board surface 301. The plate body 602 has a function of reducing the friction coefficient between the upper surface thereof and the sliding portion 31A. The upper surface of the plate body 602 is a smooth flat surface so that it is possible. The plate body 602 is made of a material such as a metal or a resin that has a small coefficient of friction with the sliding portion 31A. The upper surface of the plate body 602 is inclined so as to descend toward the board surface 301. The rubber 601 has such a shape that the plate member 602 can be given such an inclination.
Next, the lower surface of the installation leg 30 of the inclinometer 10, more specifically, the lower surface of the sliding portion 31 </ b> A provided in the movable portion 31 is placed on the upper surface of the plate body 602 of the fixed object 600 and the weight of the inclinometer 10 is set. Call. Then, since the upper surface of the plate body 602 is inclined downward toward the board surface 301 and the friction coefficient between the upper surface of the plate body 602 and the sliding portion 31A is small, the sliding portion 31A is located above the plate body 602. Toward the board surface 301 until the tip of the installation leg 30 comes into contact with the board surface 301. Accordingly, the tip of the installation leg 30 is brought into contact with the board surface 301 without particularly applying a force that pushes the inclinometer 10 toward the board surface 301 on the inclinometer 10.
From this point onward, the process is the same as when the inclination angle of the board surface 301 is measured using the nail 302. The inclination angle of the virtual axis of the inclinometer 10 is determined by the two points where the installation legs 30 and 40 abut against the board surface 301. Also in this case, the operator can perform necessary work such as adjustment of the inclination angle of the panel surface 301 while looking away from the inclinometer 10 while looking at the inclination angle of the panel surface 301 indicated by the inclinometer 10. .
