本考案は、測量機の視準線方向をターゲツト側
より概略掴むためのポイント設定用コリメータ装
置に関する。[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a point setting collimator device for approximately grasping the line of sight direction of a surveying instrument from the target side.
（考案の背景）
従来、杭打ちのためのポイントを測量機を用い
て設定する作業がある。その場合、測距、測角の
行える測量機によつてポイントの方向を視準し、
測距のためのターゲツトを視準線方向に前後させ

方向に合わせることは時間を要する煩雑な作業で
ある。そこで、ターゲツトの側で測量機の視準線
方向を概略掴むためのポイント設定用コリメータ
装置が提案されている。(Background of the idea) Conventionally, there has been work to set points for piling using a surveying instrument. In that case, the direction of the point is sighted using a surveying instrument that can measure distance and angle.
Set the target for distance measurement by moving it back and forth in the sight line direction. At this time, it is a time-consuming and complicated task for the target side to receive movement direction instructions from the operator of the surveying instrument using a transceiver or the like and to align the target with the line of sight. Therefore, a point setting collimator device has been proposed to roughly grasp the direction of the line of sight of a surveying instrument on the target side.
このものは、コリメータレンズの焦点面に光軸
を挾んで左右に色の異なる拡散板、例えば緑色と
赤色、を配設し、その背後に光源を設けて構成さ
れており、このコリメータ装置を測量機と光軸が
平行でかつ又同一鉛直面内にあるように測量機に
取り付ける。 This device consists of diffusing plates of different colors, for example, green and red, placed on the left and right sides of the focal plane of the collimator lens, sandwiching the optical axis, and a light source behind them. Attach it to the surveying instrument so that the instrument and the optical axis are parallel and in the same vertical plane.

分が測量機の視準線付近にいることがわかるので
ある。 Then, when you look at the surveying instrument near the target, the light from the collimator device enters your eyes, and you can tell by its color whether you should move to the left or right. In other words, since we know in advance what color will be on either side of the line of sight of the surveying instrument, we can know in advance that we are looking at green, and if we move to the right we should see red. If there is one, move to the right side while holding the target and stand at the exact border point where you can see the green and red colors, and you will know that you are almost in the line of sight of the surveying instrument.

光量損失が多く、従つて遠距離では光源の発光量
をかなり大きくしなければ見難いという欠点があ
つた。また、左右の識別を色によつて行つていた
ので、このことも遠距離では使い難いという欠点
につながつていた。 However, as mentioned above, conventional collimator devices use a diffuser plate as a secondary light source, so
The disadvantage is that there is a large amount of light loss, and therefore it is difficult to see at long distances unless the amount of light emitted by the light source is increased considerably. In addition, since left and right were distinguished by color, this also led to the drawback that it was difficult to use at long distances.

本考案は、比較的遠距離でも使い易いポイント
設定用コリメータ装置を得ることを目的とする。(Purpose of the invention) The object of the invention is to obtain a collimator device for point setting that is easy to use even at relatively long distances.

A collimator lens 2 is fixedly installed in the apparatus main body 1, and a triangular prism 3 is arranged so that its ridgeline coincides with a vertical line passing through the focal point (perpendicular to the plane of the paper) on the optical axis l of the collimator lens 2. Reflective surface 3 of chevron prism 3
a and 3b face the direction of the collimator lens 2 and are tilted at equal angles in a direction opposite to the optical axis l.
On the reflection optical axis l 1 of one reflection surface 3a, there is a first
The red light emitting diode 4 is also connected to the other reflective surface 3.
A second red light emitting diode 5 is disposed on the reflection optical axis l 2 of b. The first red light emitting diode 4 and the second red light emitting diode 5 are driven by a drive circuit 7 on the substrate 6 so that they are lit at different frequencies. In this example, the first red light emitting diode 4 lights up (infinite frequency), and the second
The red light emitting diode 5 is driven to blink at a predetermined frequency.

あるように取り付けられる。 The collimator device shown in Fig. 1 is attached to, for example, the arm of a surveying instrument having distance measurement and angle measurement functions by means of a mounting device (not shown), so that the optical axis of the collimating telescope and the optical axis l are parallel to each other. And they are installed so that their respective optical axes lie within the same vertical plane.

ち、測量機の視準線方向にいることになる。 Now, according to the structure of the embodiment as described above, when an operator on the target side, which has a prism as a target for light wave distance measurement, looks toward the surveying instrument to which the collimator device is fixed, the first The light emitted from the red light emitting diode 4 is reflected by the reflective surface 3a of the prism 3, and then condensed slightly ahead of the front focal point of the collimator lens 2, and then diffused to the area below the optical axis l in the figure. However, on the contrary, the light emitted from the second red light emitting diode 5 is diffused to the area above the optical axis l, so if you are on the right side of the optical axis l (above in the figure), you will see a flashing red light. When the user is on the left side of the optical axis l (lower in the figure), red lighting light is observed. Therefore, if you stand on that boundary,
The operator is located on the optical axis l of the collimator lens 2, that is, in the direction of the line of sight of the surveying instrument.

のフイードバツクが行われる。 Note that in the above example, the ridgeline of the chevron prism 3 is set on the optical axis, but it is sufficient that this position is substantially on the optical axis. Furthermore, it is not necessary to place the light emitting diodes 4 and 5 exactly on the optical axes l 1 and l 2 . That is,
This is because the collimator device for point setting is used for the purpose of roughly grasping the collimation direction of the surveying instrument from the target side. In order to accurately determine the points for piling, etc., position information is fed back by radio or the like from a surveyor on the surveying instrument side to a worker on the target side.

点灯と変わりがない）。 In addition, in the above embodiment, as an example of changing the blinking frequency of two light emitting diodes, one was turned on and the other was blinked, but it is also possible to change the blinking frequency of both to a sufficient degree that they can be distinguished (the eye cannot follow If the blinking cycle becomes short enough, from the worker's perspective, it is no different from a light on).
さらに以上の実施例では、左右の識別を行うよ

略掴むことができる。 Furthermore, in the above embodiment, the left and right discrimination is performed, but the outer periphery of the device main body 1 is set to the optical axis l.
It has a cylindrical shape with the center at , and the mounting device holds the outer periphery of the device main body 1 so as to be rotatable around the optical axis l.
If it is possible to position and fix by rotating 90 degrees, it is possible to approximately grasp the positional deviations in the horizontal and vertical directions with respect to the collimation direction simply by rotating the device main body 1 with respect to the mounting device.

良い。 Furthermore, if a quadrangular pyramidal prism having four reflective surfaces as shown in FIG. 2 is used instead of the chevron-shaped prism 3, it is possible to identify the top, bottom, left, and right without rotating the main body 1 of the device. In this place,
The apex of the quadrangular pyramid may be aligned with the focal point of the collimator lens 2, and the opposing reflecting surfaces may be used for vertical and horizontal separation, respectively. In that case as well, the angles that each reflecting surface makes with the optical axis are equal, and the light emitting diode is disposed on the optical axis branched by each reflecting surface. In this case, the four light-emitting diodes for identification on the top, bottom, left and right sides may be driven at the same time by changing the blinking frequency of each, but it is easier to operate if they are driven separately for the top, bottom, left and right. is good.
なお、以上の説明では光路分岐用反射面の各々
と光軸とのなす角度が等しくなるように説明した
が、反射面の傾きは必ずしも等しい必要はない。
その場合には、光軸の位置に合わせて発光ダイオ
ードの位置を調整すれば良い。 In addition, although the above description was made so that the angles between each of the optical path branching reflecting surfaces and the optical axis are equal, the inclinations of the reflecting surfaces do not necessarily have to be equal.
In that case, the position of the light emitting diode may be adjusted according to the position of the optical axis.
（考案の効果）
以上述べた如く本考案によれば、拡散板を用い
ないために光量損失が少なく、かつ点滅周波数の
差による識別を採用しているので、遠方で見易い
波長の光源を用いることができる。(Effects of the invention) As described above, according to the invention, since a diffuser is not used, there is little loss of light quantity, and since the identification is based on the difference in blinking frequency, it is possible to use a light source with a wavelength that is easy to see from a distance. I can do it.
