2. Description of the Related Art Conventionally, a reflection mirror for an optical distance meter cannot measure an angle only with a reflection mirror, so that a reflection mirror and a target plate are used together. That is, as shown in FIG.
There is known a reflecting mirror stationary type reflecting mirror and a supporting device in which a reflecting prism 52 serving as a collimation center is attached to the target lens 1, and a target plate 53 is arranged on the outer periphery of the reflecting prism 52. However, such a reflecting mirror stationary type reflecting mirror for an optical distance meter and a supporting device use the target plate 53 and the leveling table 51, and there is a problem in workability. Therefore, the leveling table 51 is not used. , A reflector support device for an optical distance meter, which is attached to a pole and has excellent workability, has been proposed.

At this time, the reflecting mirror body 11 is composed of a prism, the collimation center of the virtual target 22 is on the vertical (center of the surveying pole P) 24 of the measuring point, and the virtual target 22 is the reflecting mirror body 11. Since the ring 20 is attached with the space X between the front surface of the reflector main body 11 and the ring 20 so as to be positioned on the virtual reflection surface 25 of the virtual target 22.
Can be positioned on the virtual reflecting surface 25 of the reflecting mirror body 11. Therefore, in addition to the distance measurement, the angle measurement can be performed as in the case of using the target. Moreover, it suffices if there is only the space between the surveying pole P and the reflecting mirror 10, and it can be easily arranged in the vicinity of the obstacle because it does not require a space like a conventional target plate, and it is compact and portable. It is easy and the workability is improved.

Further, as shown in FIG. 4, since the collimation center and the swing center coincide with each other, the tilt mechanism can swing the virtual target 22 about the collimation center.
It is possible to prevent the collimation center of the virtual target 22 from moving even when the reflecting mirror 10 is tilted. For this reason, it is possible to perform the distance measurement and angle measurement by arranging the reflecting mirror 10 for the light wave distance meter toward the light wave distance meter side. Even if the bulging portion is directly formed on the ring 20 without using the hollow circular member, the same effect as the above can be obtained.
