るかどうかを確認できるようにしてある。[Prior Art] In a device using a light beam such as a laser, a laser length measuring device, and the like, a light beam projector and a collimating telescope are provided in combination with the light projector so that the irradiation point of the light beam is at a desired position. You can check whether it is
斯かる装置では、投光器と視準望遠鏡との正確な光軸合
わせが必要となるが、従来光軸合わせは第２図に示すよ
うな方法で行なわれていた。In such an apparatus, accurate alignment of the optical axes of the projector and the collimating telescope is required, but the conventional optical axis alignment has been performed by the method shown in FIG.

するよう、前記調整機構を調整する。The collimating telescope 3 is attached to the machine base 2 to which the projector 1 is attached via an adjusting mechanism (not shown). Next, a target 4 for aligning the optical axis is set up at a predetermined distance l (for example, 100 m), and a light beam 5 from the projector 1 is set on the target 4.
Irradiate. The operator looks into the collimation telescope 3 with the light beam 5 irradiating the target 4 and adjusts the adjusting mechanism so that the cross mark 6 provided in the field of view of the collimation telescope and the irradiation point of the light beam 5 coincide with each other. adjust.
［発明が解決しようとする課題］ 然し、上記した投光器１と視準望遠鏡３との光軸を合わ
せる方法では、以下にのべるような不具合がある。[Problems to be Solved by the Invention] However, the above-described method of aligning the optical axes of the projector 1 and the collimation telescope 3 has the following problems.
光軸合わせ用のターゲット４を投光器１、視準望遠鏡３

ｌ）であった場合にはやはりｅ″の誤差を生じてしま
い、測定精度の低下を招くことになる。The target 4 for optical axis alignment is the projector 1, the collimation telescope 3
When the optical axis is aligned by setting the position at a distance of 1 more, when the distance between the objects to be measured is l '(> l), an error of e'is generated and The distance is l ″ (<
In the case of l), an error of e ″ is still generated, and the measurement accuracy is deteriorated.

点が確認できなくなるという問題もある。Further, when the optical axis is aligned, the optical axis of the projector 1 and the optical axis of the collimation telescope 3 become closer to parallel as the distance l is increased, which is caused by the change in the distance to the object to be measured. The error is reduced. Therefore, the installation distance of the target 4 for optical axis alignment becomes a value of 100 m or more. For this reason, it is inevitable that the optical axis alignment work will be a large-scale work, and it will be a collaborative work by a plurality of people, and will require a vast site. Further, when the distance is increased, there is also a problem that the intersection point on the target from the projector cannot be confirmed depending on the magnification of the collimation telescope.
