Description

[Detailed Description of the Invention] (Industrial field of application) This invention relates to a nail width measuring gauge of a pachinko machine used to measure the gap between the nails hit on the board cell plate of the pachinko machine. is there.

(Prior Art) Originally, in pachinko games, in order to maintain an appropriate balance between the advantages and disadvantages of the customer and the hall, the nail width on the prize hole must be constantly adjusted. Therefore, conventionally, the distance between the nails is measured by using a nail width measuring gauge in which two kinds of ball gauges of different sizes are fixed to both ends of the gauge rod.

(Problems to be solved by the device) However, this known measuring gauge cannot fully support the current situation where four different sizes of pachinko balls are used, and it is not possible to accurately and completely measure them. I didn't want it. In addition, there is a drawback that the conventional measuring gauge cannot immediately respond to the trend of today that the width between the nails is significantly increased. Further, for convenience of use, when each ball gauge is engraved with its respective size, there is a problem in that the sphere itself becomes weak and the perfect circle is impaired so that it cannot be used.

Further, the inventor of the present application has already researched and developed this kind of measuring gauge using a ring gauge, but this ring gauge has another point in terms of workability and operability. For example, if the ring gauge is inserted at an angle to the nail, the gap between the nails may not be accurately measured. Therefore, the inventor of the present application has conducted further research and experiments to search for practicality in the case of the above ring gauge, and as a result, it is a nail width measurement gauge using the ball gauge of the present invention, which is extremely practical and has excellent operability, which is optimal for measurement between nail gaps. It was a successful invention.

(Means for Solving Problems) The present invention has been made to solve the above problems, in which the ball shafts 1a and 1b of various sizes having different diameters are attached to the handle shaft 2 fixed to the respective tip portions. , At least a part of the flat portion 3
Nail width of a pachinko machine in which each gauge size 5 is displayed on each flat surface portion 3 as a rod body having, and the base end portion of each handle shaft 2 is detachably connectable to both ends of the rod-like handle 6. The measuring gauge is the gist.

(Operation) The nail width gauge of the present invention configured as described above is the ball gauge 1a, 1b having an appropriate diameter according to various nail gaps to be measured.
Is selected and the base end of the handle shaft 2 is connected to one end or both ends of the rod-shaped handle 6 for use. Then, if the ball gauge 1a or 1b connected via the handle shaft 2 is inserted between the nails of the pachinko machine, the gap between the nails can be measured.

Further, since the ball gauges 1a and 1b are spherical and have the same cross-sectional shape when cut in any direction, the gap between nails can be accurately measured even when the nail width measurement gauge is obliquely inserted between the nails. .

Further, since the handle shaft 2 has a flat surface portion 3 on which the gauge size 5 is displayed, it is possible to easily select a desired one from the ball gauges 1a and 1b.
It is possible to favorably prevent the perfect circles of the spherical gauges 1a and 1b from losing their shapes due to use, as compared with those in which the gauge sizes are directly marked on a and 1b.

(Embodiment) The nail width measuring gauge of the present invention will be described in detail with reference to the embodiments of the drawings.

First, 2 are various sizes with different diameters (11.06,11.02,10.9
There are many kinds such as 8,11.00,11.01,11.3,11.4,11.8,11.10,11.12. ) Ball gages 1a and 1b are handle shafts integrally fixed to the respective tip portions. Therefore, in this invention, the handle shaft 2 is formed as a bar body having a flat surface portion 3 at least in a part thereof.
In addition, each gauge size 5 is displayed by, for example, stamping or marking. A screw shaft portion 4 is provided at the base end of each shaft 2 so as to project therefrom. In FIG. 1, the handle shaft 2 is a rod having a regular square pole shape, and the outer peripheral four faces are all flat portions 3. In FIG. 2, the handle shaft 2 is a longitudinal plane in a part of the cylindrical rod body. The case where each of the flat portions 3 is formed is illustrated. Reference numeral 6 is a handle having a triangular cross-sectional shape in which the shaft is slightly inwardly concave on three sides and having a twisted triangular prism shape twisted in the right-hand screw direction around the center line of the shaft.
Female grip portions 7 to which the screw shaft portions 4 of the handle shafts 2 are detachably connectable are provided at both ends of the handle 6, respectively. Similar to the handle shaft 2, the shape of the handle 6 is not limited to the shape of the embodiment shown in the drawings, but may be any shape of a rod, and may be knurled on the outer peripheral surface. When the handle 6 has the shape of the embodiment shown in the drawings, when the handle is gripped and held with fingers, the hand and fingers are not partially pressed and fatigue is small even if it is held for a long time.

(Effect of device) Since this device has the above-described structure, it is necessary to provide a large number of handle shafts 2 each having a large number of ball gauges 1a, 1b of various sizes with various diameters fixed to the tip. Therefore, it is possible to selectively select from among the above-mentioned many handle shafts 2 as needed and connect it to one end or both ends of the handle 6 to easily measure the distance between any nails and finely and accurately It has the effect of making fine adjustments. In particular, since each handle shaft 2 can be detachably connected to both ends of the handle 6 or only to one end thereof, either handle can be detachably connected according to the need. The distance can be measured.

And especially in this invention, various sizes of ball gauges 1a, 1
Since each gauge size 5 is displayed on each plane portion 3 of each handle shaft 2 to which each b is fixed, it is very easy to see,
There is no difficulty in finding the required size from a large number of measuring gauges, and it is useful as well as the conventional ball gauge with the size stamped, so that the perfect circle of the sphere can be obtained. It has excellent effects such as no deformation or loss of shape.

Further, since the ball gauges 1a and 1b are spherical, the nail gap can be accurately measured even when the nail width measuring gauge is obliquely inserted between the nails. Therefore, the gap between the nails can be measured accurately and easily.

Further, since each handle shaft 2 is compatible with the handle 6, one or two handles 6 can be used in various ways with good workability.
The gauge size 5 can be displayed on the flat surface portion 3 of the handle shaft 2 by various means such as engraving, special printing, and sticking label.
