Description

  The present invention relates to an interval measuring device that measures an interval of a measurement target part.

  Conventionally, as an interval measuring device for measuring an interval between measurement object parts, for example, a nail measurement for a gaming machine that is provided on a board surface of a pachinko gaming machine as a measurement object part and measures an interval between two adjacent nails. There is a device, and at a game store, the nail interval is measured using this nail measuring device for gaming machines, and the nail of the gaming machine is adjusted.

Now, the degree of adjustment of the distance between the nails provided on the board surface of the gaming machine (in particular, the so-called “life nail (the distance between the two nails provided above the starting winning opening)”) Therefore, it is necessary to grasp the unit of 1/100 mm as the operation level, and a highly accurate measurement value is required. In order to measure the measurement value with high accuracy, it is necessary to perform measurement in a state where the nail measuring device for the gaming machine is in a horizontal state and along the board surface of the pachinko gaming machine.
Therefore, as shown in FIG. 6 (a), as a nail measuring device for gaming machines, a pair of measuring elements 103 and 103 that are in contact with two adjacent nails 102 and 102 on the board surface 101 from the inside, and one measurement An operation lever (not shown) for moving the probe 103 close to or away from the other probe 103, an L-shaped reference arm 104 having a contact portion 104a at the tip, and a level (for level adjustment) There has been proposed a nail measuring apparatus 100 for a gaming machine configured to include (not shown) (see Patent Document 1).

In this nail measuring device 100 for gaming machines, the user operates the operation lever so that the measuring elements 103 and 103 come close to each other, and the operation lever is in a state where the entire contact portion 104a of the reference arm 104 is brought into contact with the board surface 101. Are operated so that the measuring elements 103 and 103 are separated from each other, the measuring elements 103 and 103 are brought into contact with the insides of the respective nails 102 and 102, and are further leveled by a level, whereby two nails are obtained. The interval between 102 and 102 is measured.
In the above-mentioned nail measuring apparatus 100 for gaming machines, it is possible to adjust the level with reference to the level, but to determine whether or not it is along the board surface 101, adjust with reference to the level. I can't do it. Therefore, by flattening the contact portion 104a of the reference arm 104, it is determined whether or not the entire contact portion 104a of the reference arm 104 is in contact with the board surface 101 and whether or not the board arm 101 is along the board surface 101. It was.
JP 2003-299788 A

  Thus, conventionally, whether or not the entire contact portion 104a of the reference arm 104 is in contact with the board surface 101 is determined based on whether or not the board surface 101 is along. However, in such a determination method, it is difficult for the user to know as a sensation whether the entire contact portion 104a of the reference arm 104 is in contact with the board surface 101 or only one end of the contact portion 104a of the reference arm 104 is in contact. As shown in FIG. 6B, although the one end of the contact portion 104a of the reference arm 104 is in contact with the board surface 101 and the other end is inclined and inclined, the entire contact portion 104a of the reference arm 104 is tilted. There is a possibility that the distance between the nails is measured by misunderstanding that the contact is in contact with the board surface 101.

  The present invention has been made in view of the above circumstances, and its purpose is to clarify the allowable range of whether or not the user is inclined with respect to the base surface, and to make the determination easy. An object of the present invention is to provide an interval measuring device capable of deriving a measurement value in a high state.

According to a first aspect of the present invention, there is provided a distance measuring device for measuring a distance between measurement target portions provided on a base surface, and a reference having a contact portion extending in a direction along the base surface and addressed to the base surface at the time of measurement. An arm and a pair of measuring elements for measuring a distance between the measurement target parts, and a protrusion that protrudes toward the base surface is provided on the contact part, and both ends of the contact part are separated from the base surface during measurement. It is separated, and only the projecting portion comes into contact with the base surface, so that it becomes unstable with respect to the base surface .

The invention according to claim 2 is characterized in that the protrusion is hemispherical.
The invention according to claim 3 is characterized in that the protrusion is located in a substantially central portion of the measurement target portion in the contact portion.

  According to the first aspect of the present invention, when the base surface and the reference arm contact portion are within an allowable range that the base arm and the reference arm contact portion are not inclined, the reference arm contact portion is not in contact with the base surface. On the other hand, when the protrusion and the one end of the reference arm contact part are in contact with the base surface, the base surface and the reference arm contact part are tilted more stably than in the allowable range. It is easy to determine whether or not it is within the allowable range. In addition, by actively generating an unstable state, it is possible to alert the user to which position is more appropriate, and the measurement value can be derived with high accuracy.

According to the second aspect of the present invention, the portion where the base surface and the projection are in contact with each other at the time of measurement is reduced and the degree of anxiety is increased, so that attention can be further urged.
According to the third aspect of the present invention, it can be determined with higher accuracy whether or not it is inclined with respect to the base surface.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a perspective view of the interval measuring device. In FIG. 1, the main body 1 of the interval measuring device is set to a size that can be carried with one hand. The main body 1 is provided with a mechanism portion storage portion 2 covered with a cover on the left side in FIG. 1 and a grip portion 3 covered with rubber on the right side.
As shown in FIGS. 2 and 3, the mechanism unit storage unit 2 is provided with a metal reference arm 4 and a pair of measuring elements 5 so as to protrude forward. Of these, the reference arm 4 integrally has a protruding portion 4a protruding forward, and an abutting portion 4b that is directed upward at the tip of the protruding portion 4a and extends in a direction perpendicular to the protruding portion 4a. In addition, the mechanism unit storage unit 2 is provided in a fixed state. A substantially central portion of the abutting section 4b, butt raised portion 7 which forms a hemispherical provided.

In addition, one of the pair of measuring elements 5 and 6 includes a protruding part 5a that protrudes forward and overlaps the protruding part 4a of the reference arm 4 from above, and the protruding part 5a. The measuring part 5b bent upward at the tip part is integrally provided, and is provided in a fixed state in the mechanism part storage part 2. The amount of protrusion of the probe 5 from the mechanism unit storage unit 2 is set to be shorter than that of the reference arm 4, and therefore the measurement unit 5b is arranged closer to the mechanism unit storage unit 2 than the abutting unit 4b.
The other measuring element 6 includes a protruding part 6a that is arranged beside one measuring element 5 and protrudes forward, and a measuring part 6b that is bent upward at the tip of the protruding part 6a. It is provided integrally so that it can move in the direction of approaching and separating from the one measuring element 5. The measurement part 6b is positioned on the mechanism part storage part 2 side with respect to the abutting part 4b and next to the measurement part 5b.

  An operation lever 8 is provided on the gripping part 3 side of the lower part of the mechanism part storage part 2. The operating lever 8 is connected to the measuring element 6 inside the mechanism housing 2 and is urged away from the grip 3 by a spring, for example, as an elastic body, and the operating lever 8 is pressed. Thus, the measuring element 6 comes close to the measuring element 5 and the pressing is released, so that the measuring element 6 is separated from the measuring element 5.

  Further, the mechanism unit storage unit 2 is provided with a level 9 for setting the horizontal state of the main body 1 with respect to the ground, and a digital meter 10 for digitally displaying an interval between the measuring elements 5 and 6. . The digital meter 10 is provided with a power switch 10a and a zero switch 10b. The digital meter 10 always digitally displays the current interval between the measuring parts 5b and 6b of the measuring elements 5 and 6 when the power is turned on.

The operation and effect of the present invention will be described below.
First, the user grips the grip portion 3 with one hand and operates the operation lever 8 with, for example, the index finger or the middle finger. In a non-measurement state in which the user does not operate the operation lever 8, the operation lever 8 is positioned on the side away from the gripping portion 3, and as shown in FIG. Has been.

  For example, before measuring the distance between two nails of a pachinko gaming machine as a measurement target portion, the user presses the power switch 10 a of the digital meter 10 to turn on the power of the digital meter 10. Then, the user holds the grip portion 3 with one hand, and presses the operation lever 8 toward the grip portion 3 side (the side that opposes urging by the elastic body) with, for example, the index finger or the middle finger, thereby causing the measuring elements 5 and 6 to move. Close. In this state, the user sets a gauge (not shown) for setting the interval between the measuring units 5b and 6b of the measuring elements 5 and 6 as a reference interval between the measuring units 5b and 6b of the measuring elements 5 and 6. And the pressing operation of the operation lever 8 is released. Then, the reference interval is set by pressing the zero switch 10b. This reference interval indicates a zero reference value set with reference to a gauge set at a desired interval (for example, 10 mm), and how much the difference between the two nails to be measured deviates from the zero reference value. It is a guide used to quantify whether or not

Next, the case of measuring the distance between two nails of a pachinko gaming machine will be described with reference to FIGS.
The user brings the measuring elements 5 and 6 close to each other by, for example, pressing the operation lever 8 toward the grip 3 with the index finger or the middle finger. In this state, the user places the abutting portion 4b of the reference arm 4 between the life nails provided in the pachinko gaming machine (the two nails 11 and 11 located at the upper part of the so-called starting winning opening) and the board surface (base surface). And the lower edges of the left and right ends of the abutting portion 4b are in contact with the upper portions of the nails 11 and 11. Then, the user releases the pressing of the operation lever 8 to bring the measuring parts 5b and 6b of the measuring elements 5 and 6 into contact with the insides of the nails 11 and 11, and the main body 1 is in a horizontal state by the level 9 Set to be. Further, the user sets the state in which both ends of the abutting portion 4b of the reference arm 4 are separated from the board surface 12 and only the projecting portion 7 is in contact with the board surface 12 (at this time, the projecting portion 7 provided on the abutting portion 4b). Is arranged at the substantially central portion between the nails 11 and 11), and the measured value displayed on the digital meter 10 is confirmed. The reference arm 4 is provided so as to protrude a predetermined length with respect to the measuring parts 5b and 6b of the measuring elements 5 and 6, so that the measuring parts 5b and 6b of the measuring elements 5 and 6 are always constant from the board surface 12. The distance between the desired positions between the nails 11 and 11 can be measured.

  As described above, the allowable range for determining whether or not the state in which both ends of the abutting portion 4b of the reference arm 4 are separated from the board surface and only the protrusion 7 is in contact with the board surface 12 is inclined with respect to the board surface 12 is determined. Is set. When it is within this allowable range, only the projecting portion 7 is in contact and both ends of the abutting portion 4b of the reference arm 4 are separated from each other. Furthermore, since the projection 7 and one end of the reference arm 4 come into contact with the board surface 12 when it is out of the allowable range, the state is more stable than when it is within the allowable range. Therefore, the user can easily determine the allowable range of whether or not the main body 1 is inclined with respect to the board surface 12 based on whether the main body 1 is in a stable state or an unstable state. In addition, by actively generating an unstable state, the user can be alerted as to which position is appropriate, and the user carefully measures between the nails 11 and 11. To come.

Moreover, since the projection part 7 formed in hemisphere is provided in the contact part 4b, when only the projection part 7 contact | abuts with the board surface 12, there are few parts to contact | abut and it can increase an instability degree. Therefore, it is possible to call the user more attention as to which position is appropriate.
Further, when the user measures between the nails 11, 11, the projecting portion 7 is provided on the abutting portion 4 b so as to be disposed at a substantially central portion between the nails 11, 11. It can be judged with higher accuracy whether or not it is tilted.
