[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail spacing measuring device for a pachinko machine for measuring the spacing between a large number of nails implanted in a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Publication No. 4-46152 discloses a nail spacing measuring instrument for a pachinko machine for measuring the spacing between a large number of nails implanted in a pachinko machine. As shown in FIG. 14 and FIG. 15, the tip of a pair of measurement arms 101 and 102 which can be opened and closed and urged in a direction away from each other by a spring (not shown) has the same diameter as the pachinko ball. Sphere part 10 obtained by dividing the sphere into two
3 and 104 are integrally formed, and each of the divided ball portions 103 and
Pins 105 and 106 project from the outer surface of 104, and the pins 105 and 106 are shifted upward from the centers of the divided ball portions 103 and 104 by the radius of the nail.

In order to measure the distance between the nails, a pair of measuring arms 101 and 102 are closed against a spring, and then divided ball portions 103 and 104 are inserted between a pair of nails P to be measured. , Pins 105 and 10 on a pair of nails P
Put 6 on. Here, after the tip of the divided ball portion 103 is brought into contact with the board surface W of the pachinko machine, a pair of measurement arms 10
When the springs 1 and 102 are opened by the urging force of the spring, the divided ball portions 103 and 104 come into contact with the nail P. In this state, the distance between the pair of measurement arms 101 and 102 (the divided ball portion 10
By reading the value of a gauge (not shown) for measuring the interval of 3,104), the interval of the nail P can be measured.

[0004]

In the conventional structure, since the divided spheres 103 and 104 are spherical, the center position C of the divided spheres 103 and 104 is set as shown in FIG.
₁ is located on the axis D connecting the center of the nail P and is separated from the board surface W by a substantially radial dimension r of the pachinko ball (FIG. 1).
5) is a condition under which accurate measurement can be performed. That is, as shown by the dashed line in FIG. 15, when the measuring arm 101 (102) is inserted obliquely in the vertical direction, the position of the pin 105 (106) is
Shifted to the side, the pin 105 (106) results central position C ₂ blastomeres unit 103 (104) as the center becomes a state shifted upward from the center position C ₁ of the normal to the measurement error. That is, as shown in FIG. 16 (B), since the center position C ₂ blastomeres unit 103 (104) is shifted upward from the axis D which connects the center of the nail P, the actual distance L ₁ is greater than the dimensions of the nail P It is measured as L _2.

Therefore, in order to perform accurate measurement, it is necessary to measure the measurement arms 101 and 102 at right angles to the board surface of the pachinko machine, that is, while maintaining a horizontal posture. Requires intuition and skill.
Moreover, the divided ball portions 103 and 104 are inserted between the pair of nails P to be measured, and the pins 105 and 10 are placed on the pair of nails P.
Even if the measurement arms 101 and 102 can be held in a horizontal posture in a state where the pair of measurement arms 101 and 102 are placed, when the pair of measurement arms 101 and 102 are subsequently opened, the pins 105 and 106 are opened.
Moves while sliding on the nail P, and the measuring arms 101 and 10 are moved by resistance at that time and bending of the nail P.
There is a problem that it is difficult to secure the horizontal posture of No. 2 and the measurement is not stable.

Further, in the conventional structure, the divided spherical portion 103,
After inserting 104 between a pair of nails P to be measured,
When the pair of measurement arms 101 and 102 are opened, the divided sphere 1
03 and 104 are brought into contact with the nail P. At this time, since an impact force is applied to the nail P by a spring which constantly urges the pair of measurement arms 101 and 102 in the opening direction, the adjusted interval of the nail P may be changed.

Further, in the conventional structure, when the pair of measuring arms 101 and 102 are opened, the pair of measuring arms 10
The interval of 1, 102 is a structure that is opened to a sufficiently large dimension with respect to the interval of the nail to be measured. Therefore, in the next measurement, the pair of measurement arms 101 and 102 must be closed smaller than the distance between the nails to be measured, so that the pair of measurement arms 101 and 102 must be opened and closed greatly each time measurement is performed. There was a drawback that quick measurement could not be performed.

[0008] It is an object of the present invention to provide a nail spacing measuring instrument for a pachinko machine capable of solving such a conventional problem, performing a stable measurement, and weakening the impact force on the nail during the measurement. To provide. Another object of the present invention is to provide a nail spacing measuring instrument for a pachinko machine capable of accurately maintaining a horizontal position of a measuring arm without requiring intuition or skill, and capable of performing quicker measurement. Is to do.

The nail spacing measuring instrument for a pachinko machine of the present invention comprises: a pair of openable and closable measuring arms each having an abutment at a tip thereof; and a measuring and displaying means for measuring and displaying the distance between the pair of measuring arms. One end side is fixed in a state protruding from the outer surface of the one contactor, and the other end side is extended in parallel with the opening and closing direction of the pair of measurement arms and penetrates through the other contactor. And a guide pin protruding from the outer surface thereof, and one of the pair of measurement arms is provided with a level which can detect inclination in all directions.

[0012]

When measuring the spacing between nails of a pachinko machine, a pair of measuring arms are closed, a contact is inserted between the nails to be measured in this state, and a guide pin is placed on the nail. Then, open the pair of measurement arms. At this time, the guide pin is fixed to only one abutment and penetrates through the other abutment and projects from the outer surface thereof. The contactor does not receive the frictional resistance of the nail until it comes into contact with the nail, so that a stable measurement can be performed. After the outer surface of each abutment contacts the nail, the measurement display means is read. As the measurement display means, a dial gauge is used in which the spindle urges the other measurement arm in a direction separating from the other measurement arm, and an air damper mechanism for reducing the moving speed of the spindle in the urging direction is used. Since the measuring arm moves away from one measuring arm at a slow speed, it is possible to reduce the impact force of each contacting element when it comes into contact with the nail.

Further, in a nail spacing measuring instrument for a pachinko machine in which a level is provided on one of a pair of measuring arms, there is no need for intuition or skill, while observing the inclination in all directions. The measurement arm can be accurately maintained in a horizontal position. By this, for example, even if there is a vertical inclination of the board surface or a horizontal inclination of the nail to be measured, the measuring arm can be accurately maintained in a horizontal position without being affected by these, so that accurate measurement can be performed. I can do it. Further, if a structure provided with an interval setting mechanism for regulating a maximum separation distance between the pair of measurement arms is provided between the pair of measurement arms,
Since the maximum separation distance between the pair of measurement arms can be regulated according to the distance between the nails to be measured, quick measurement can be performed.

The measuring elements 11 and 21 are described in detail in FIGS.
As shown in FIG. 8, holders 61A and 61B and divided cylindrical portions 62A and 62B as abutments integrally formed at the tips of the holders 61A and 61B are provided. A notch 63 on the outer side of each of the holders 61A and 61B is provided to escape the nail head.
A, 63B are formed. The divided cylindrical portion 62A,
62B is formed in a shape obtained by dividing a cylindrical body having an outer peripheral curved surface substantially equal to the diameter of a pachinko ball into two along the axial direction thereof. In detail, the front and rear sides of the cylindrical body having the outer peripheral curved surfaces 64A and 64B substantially the same as the diameter of the pachinko ball are cut into planes 65A, 66A and 66B parallel to each other along the axial direction, and the rear planes 66A and 66B are substantially cut. It is formed in such a shape that it is divided from the center toward the center of the cylindrical body, and is further diagonally divided toward the outer peripheral curved surface side of the divided cylindrical portion 62B.
The outer peripheral curved surfaces 64A, 64B are attached to the tips of the holders 61A, 61B, respectively, outwardly, and the axis direction is orthogonal to the measuring arms 1, 2 and the opening / closing direction thereof. I have.

A guide pin 67 is provided which protrudes from the outer peripheral curved surface of each of the divided cylindrical portions 62A, 62B in the opening and closing directions of the measurement arms 1, 2. One end of the guide pin 67 has an outer peripheral curved surface 64A of the one divided cylindrical portion 62A.

A V-groove 68A is formed on the front flat surface 65A of the one divided cylindrical portion 62A at substantially the same height position as the guide pin 67 and in parallel with the guide pin 67, and the V-groove 68A comes into contact with the board surface W of the pachinko machine. A contact pin 69 is provided in parallel with the guide pin 67.

Next, the operation of the first embodiment will be described. When measuring the nail interval of the pachinko machine, the interval between the outer peripheral curved surfaces 64A and 64B of the divided cylindrical portions 62A and 62B is set to a dimension slightly larger than the interval of the nail to be measured. For this, the adjustment shaft 53 of the interval setting mechanism 5 is rotated. For example, when the adjustment shaft 53 is rotated 90 degrees from the state shown in FIG. 3, the cam disc 55 is rotated as shown in FIG. 5, so that the maximum separation distance between the measurement arms 1 and 2 (the divided cylindrical portion 62).
A, the maximum distance 62B) the can be varied in the range of LM ₁ to L m _2.

In the measurement, the handle 12 is grasped with one hand, and the finger hook 22 is pulled in the X direction in FIG. 1 with the grasped one finger. Then, while being guided by the guide mechanism 3, the second
Is approached to the first measurement arm 1. Here, as shown in FIG. 7 and FIG.
A, 62B are inserted between the nails P to be measured, the guide pins 67 are placed on the nails P, and the contact pins 69 are in contact with the board surface W of the pachinko machine (a pair of measuring arms 1 and 2). The finger is released from the finger hook 22 in a state where the horizontal fluctuation is prevented). Then, the second measuring arm 2 is separated from the first measuring arm 1 by the urging force of the spindle 42 of the dial gauge 4 (the urging force of the built-in spring), and as a result, the divided cylindrical portions 62A and 62B are separated.
The outer peripheral curved surfaces 64A and 64B are in contact with the nail.

At this time, since the moving speed of the spindle 52 in the biasing direction is reduced by the air damper mechanism 43, the second measuring arm 2 is moved at a slow speed. Therefore, the impact force at the time when the divided cylindrical portion 62B abuts on the nail P can be reduced. Moreover, the divided cylindrical portion 6
2B does not receive the frictional resistance of the nail P until it comes into contact with the nail P, so that stable measurement can be performed.
Further, a pair of measurement arms 1 and
9, the contact point between the outer peripheral curved surfaces 64A, 64B of the divided cylindrical portions 62A, 62B and the nail P is always an axis connecting the center of the nail P to be measured, as shown in FIG. Since it is kept on the line and at a position that is approximately a fixed distance away from the board surface W of the pachinko machine, if the display value of the dial gauge 4 is read at this time, the interval between the nails P to be measured can be accurately measured. can do.

Therefore, according to the first embodiment, the divided cylindrical portions 62A and 62B are attached to the tips of the measurement arms 1 and 2 which can be opened and closed, and the outer peripheral curved surface 64 of each of the divided cylindrical portions 62A and 62B.
A and 64B are provided with guide pins 67 projecting in the opening and closing directions of the measurement arms 1 and 2, and one of the divided cylindrical portions 6
Since the contact pin 69 for contacting the pachinko board surface W is provided in parallel with the guide pin 67 on the front end face of 2A, the contact pin 6
9 prevents the horizontal wobble, and even if the pair of measuring arms 1 and 2 are raised and lowered in the vertical direction with the contact pin 69 as a fulcrum, the outer peripheral curved surfaces 64A and 64B of the divided cylindrical portions 62A and 62B and the nails. Is always kept on the axis connecting the centers of the nails to be measured, and is maintained at a position substantially constant distance from the board surface W of the pachinko machine, so that accurate measurement can be performed.

Further, since the guide pin 67 is fixed to only one of the divided cylindrical portions 62A and penetrates through the other divided cylindrical portion 62B and projects from the outer peripheral curved surface 64B, the other divided cylindrical portion is formed. Since 62B does not receive the frictional resistance of the nail until it comes into contact with the nail P, stable measurement can be performed. Further, the spindle 42 of the dial gauge 4 urges the second measuring arm 2 in a direction away from the first measuring arm 1 and reduces the moving speed of the spindle 42 in the urging direction. Since the air damper mechanism 43 is provided, the second measuring arm 2
Is separated from the measuring arm 1 at a slow speed, so that it is possible to weaken the impact force when the divided cylindrical portions 62A, 62B abut on the nail P.
