Abstract

(57) [Summary] [Structure] A pachinko that supports a split ball by a pin protruding from each split ball mounted on the nail at a position where the pair of split balls inscribes in the pair of nails of the pachinko machine. For a nail distance measuring machine of a machine, a reference unit of a length in which a parallel facing surface inside the fork of a metal block having a fork is orthogonal to the projecting end surface or the abutting surface and the upper surface of the fork. . [Effect] Even if there is a change in the external shape of the contact part of the split ball with the nail, it has an easy-to-use shape, but if this is used every time, an error will occur because of that. Without, the nail spacing can be measured.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a length reference device for a nail spacing measuring machine of a pachinko machine for preventing the occurrence of a measurement error.

[0002]

[Prior art]

 Conventionally, as a gauge for adjusting a nail gap in a pachinko machine, there has been one that uses the opening of a measuring rod provided with a pachinko ball hemisphere portion at its tip (Actual No. 1-85605), but a pachinko ball hemisphere portion. Since it takes a skill to abut the nail between the nails, it is proposed to improve this so that the pin protrudes from the outer surface of the split sphere (Jpn. No. 4-46162). There has been proposed a nail spacing measuring device for a game machine, which is provided with a calculation output means for digitally displaying the spacing value (Japanese Patent Laid-Open No. 6-98975). However, these have a drawback that it is difficult to make the split balls freely follow each other between the nails, and an error occurs in the measurement of the nail interval. Even if this problem is solved, it has been found that it still causes a measurement error.

[0003]

[Problems to be solved by the device]

 The present invention is intended to provide a device for preventing an error in a measured value when measuring a nail interval of a pachinko machine.

[0004]

[Means for Solving the Problems]

 That is, it is a pachinko machine in which a pair of split balls are inscribed in a pair of nails of a pachinko machine, and pins protruding from each split ball are mounted on the nails to support each split ball. Before the measurement of the nail spacing measuring machine of the above, the parallel facing surface inside the fork of the metal block having the fork is orthogonal to the projecting end surface or the abutting surface and the upper surface of the fork. We came to find out that we should try to set the reference length by using the standard instrument of the length.

The nail gap measuring machine of the pachinko machine is used after setting a reference length, but it has not been particularly recognized so far that it is necessary to repeat this. When the nail spacing measuring device is used repeatedly, the metal or coated part of the split sphere that comes into contact with the nail may be worn or, conversely, the components of the nail of the pachinko machine may adhere to these parts. Also causes minute changes in the shape of the dividing sphere, and the measured value displayed by the measuring machine often differs from the actual length. The present invention has solved this problem.

[0006]

[Action]

 In the present invention, prior to the nail distance measurement, as a length standard, a metal block having a bifurcated part is used in which the parallel opposing faces inside the bifurcated part are orthogonal to the projecting end face. The projecting pin of the split sphere is mounted on, and the split sphere is inscribed on the parallel opposing surfaces. Also, as another type of length standard, a metal block having a bifurcated part, in which the parallel facing surfaces inside the bifurcated part are orthogonal to the abutting surface and the upper surface of the bifurcated part, is used. The projecting pin of the split sphere is mounted on the upper surface, and the split sphere is inscribed in the parallel facing surface of the bifurcated part and the surface at the end of the fork. Set the same as the distance between parallel facing surfaces of the container. The latter of these length standards is easier to position and easier to use. In addition, it is desirable to make the gauges of these lengths with metal materials as thick as possible in order to maintain accuracy with respect to temperature changes.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples. An example of the length standard is shown in FIG. The length standard is made of steel, and a rectangular parallelepiped with a width of 25 mm, a height of 16 mm, and a depth of 12 mm is formed at the center in the horizontal direction. I am doing it. The interval between the parallel facing surfaces (1) of the bifurcated portion is formed to correspond to the diameter of the pachinko ball, and the projecting end surface (2) is orthogonal to the facing surface (1). As shown in FIG. 2, the pin (6) of the split sphere (5) of the nail gap measuring machine is placed on the projecting end face (2) of the forked part, and the split sphere (5) is parallelly opposed to the forked part as shown in FIG. After setting the outer dimension of the split sphere (5) when inscribed in the surface (1) to be equivalent to the diameter of the pachinko sphere, perform the subsequent nail interval measurement and set the plus and minus values to the standard length. The absolute value of the nail gap is displayed by adjusting the inside of the measuring machine body (5).

An example of another type of length reference is shown in FIG. The standard device of this length is made of steel, and a cube having a width of 21 mm, a height of 11 mm, and a depth of 40 mm is formed into a forked part by cutting out a cube having a side of 11 mm from the center front surface in the horizontal direction. The distance between the parallel facing surfaces (1) of the forked portions is formed to correspond to the diameter of the pachinko ball, and the upper surface (3) and the abutting surface (4) are orthogonal to the facing surface (1). In use, as shown in Fig. 4, the pin (6) of the split ball (5) of the nail gap measuring machine is placed on the upper surface (3) of the bifurcated part, and the split ball (5) is placed on the parallel opposing surfaces of the bifurcated part ( The outer dimension of the split sphere (5) when inscribed in 1) and the surface (4) at the end is set as the diameter of the pachinko sphere.

[Effect of device]

 The length reference device of the present invention has a shape that can be easily used by a nail gap measuring machine having a pin.When measuring the nail gap of a pachinko machine, if it is used in advance, it can be used as a split ball nail. Even if there is a change in the external shape of the contact part of the, the nail interval can be measured without causing a measurement error.
