2. Description of the Related Art Prior to construction, there is a possibility that there will be surveys that set various angles in construction surveys that require a new construction point as a standard for construction. It can also be easily understood from the fact that the majority of buildings are formed by right angles.

An example of conventional surveying by theodolite for setting a right angle will be described with reference to FIG. 7. When a new installation point C is provided in a direction perpendicular to the existing installation points A and B, the theodolite D is installed on the existing installation point B. install. Collimate the existing point A with theodolite D. Turn theodolite D 90 °. The surveying engineer E uses a hand gesture to indicate a point to collimate with the theodolite D. According to the instructions of the surveying engineer E, the setting worker F sets the new installation point C.
Mark. Surveying was performed by the procedure.

As described above, when the conventional theodolite is used to perform the construction survey by the conventional surveying method, the theodolite D is used for collimating the target or theodolite D.
A surveying engineer E is required to rotate the vehicle. And these tasks require skill and skill. The marking work at the new installation point C is performed indirectly by the setting worker F according to the instruction of the surveying engineer E, so it takes time,
Easy to be uncertain. There was a problem such as.

Therefore, the inventor of the present application was the 2nd of November, 1990.
According to the patent application dated 7th or December 14, 1990, basically, as shown in FIG. 5, at least two sets of radiation optical systems for emitting laser beams emitted from a light source 6 as laser beams L1 and L2. A laser beam light emitting device S, which is characterized in that it is provided with a rotary irradiating device for rotatively irradiating laser beams L1 and L2 emitted from the two sets of radiation optical systems onto mutually orthogonal surfaces, respectively. is there.

That is, in the case of the embodiment shown in FIG. 5, the laser beams emitted from the two sets of the radiation lenses 8 of the radiation optical systems arranged in the direction perpendicular to the plane parallel to the plane of the paper are respectively dihedral reflecting members. The two-sided reflecting member 13 is projected toward
Is rotated by a motor 15 and the laser beams L1 and L2 emitted from the two-sided reflecting member 13 are rotatably irradiated on planes V1 and V2 which are orthogonal to each other and are orthogonal to the paper surface.

Therefore, if the directions of the laser beams emitted from the two sets of light sources 6 are both set on the horizontal plane, the laser beam L emitted from the two-sided reflecting member 13 will be described.
1 and L2 are vertical planes V1 and V2 which are orthogonal to each other.
The upper part is rotated and irradiated. In the figure, 7 is a compensator for always keeping the laser beams L1 and L2 that are irradiating and rotating vertically regardless of the inclination of the body 1 of the light emitter S, and 9 is an electronic circuit that drives the light source 6 and the motor 15 and the like. Substrate 10, power source thereof, 14 bireflecting member support frame, 16 laser beam radiation window, 17 motor support frame.

An example of surveying for setting a right angle using the above laser beam emitter will be described with reference to FIG. 6, in which the laser beam emitter S is positioned at the intersection of the laser beams L1 and L2 located near the emitter S. Install P (the accumulation of intersections forms a vertical line) so that it coincides with the existing point B. One rotating irradiation laser beam L1 is made to coincide with the existing point A. The setting worker F directly marks the point irradiated by the other laser beam L2 orthogonal to the laser beam L1. Such a procedure.

Therefore, as compared with the above-mentioned conventional surveying example, the surveying engineer E is not required, and the labor saving of one person can be surely performed. There is no need for skill or skill for turning the theodolite D and collimating the target. The marking work of the new installation point C can be done in a short time and is accurate because the point irradiated by the laser beam L2 may be directly marked. There is an action and effect.

It should be noted that it is conventionally known that the mark at the point irradiated with the laser beams L1 and L2 is made by the laser receiver 3 as shown in FIG. In the case of FIG. 8, the laser beam L of the light emitter S is rotatably irradiated along the horizontal plane, and therefore, the laser light receiver 3 is moved vertically along the direction of the laser beam L, and the light receiving window is received. Laser beam L received on 4
Since the display window 5 for turning on the index display or the up / down arrow mark display is provided depending on the position of, the light receiver 3 is moved up or down in accordance with the arrow mark display, and the index 25 at the position where the center index display is turned on. A marking position is marked on the surface to be marked with a writing tool 26 along the line. Therefore, like the laser beams L1 and L2 in FIGS. 5 and 6,
When rotating and irradiating along the vertical plane, the laser receiver 3
Is set to be horizontal and horizontal to receive the laser beams L1 and L2, and is moved left and right to set the mark position.

[0011]

In FIG. 6, the light receiving means for the laser beam L1 at the existing point A, or
The laser beam L2 at the new installation point C can be received by the laser beam receiver 3 as described above, but the intersection P of the laser beams L1 and L2 located in the vicinity of the laser beam emitter S can be changed to the existing point B. When the light emitter S is mounted on the tripod T so as to coincide with, there is a problem that it is difficult to determine the intersection point P.

That is, in the vicinity of the existing point B, two points through which the laser beam L1 passes are obtained by the photodetector 3 so as to straddle the point B, and a line connecting the two points is drawn. Find two points that L2 passes,
A line connecting the two points is drawn, and the intersection point P of the laser beams L1 and L2 obtained by the intersection of these two lines must match the existing point B. Therefore, the above-mentioned intersection point P does not match the existing point B. Since the confirmation and the positioning operation of the laser beam light emitter S must be repeated alternately, it can be said that the work of determining the installation position of the laser beam light emitter S is extremely difficult.
