[0001]

The present invention relates to a surveying instrument support device and a surveying device.

[0002]

2. Description of the Related Art As a kind of surveying instrument, level and transit have been well known. These surveying instruments are usually used by setting the surveying instrument on a tripod stand. The tripod mount secures a certain wide triangle base area,
It is erected stably.

However, the bottom area of the tripod mount cannot always be ensured in a space required for stable standing. For example, when a survey is performed in a narrow place indoors in a house under construction, a building, or the like, it often occurs that it is difficult to secure a bottom area necessary for stable standing of a tripod stand.
In such a case, conventionally, there has been no alternative but to reduce the bottom area of the tripod stand and perform surveying in an unstable standing state. For this reason, in some cases, a survey error may occur.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a surveying instrument supporting device and a surveying device which can stably support even a small place.

FIG. 13 is a diagram showing a part of a surveying instrument to which a laser oscillation device is attached, and FIG. 14 is an enlarged view showing a mounting structure of the laser oscillation device in the surveying instrument shown in FIG. The surveying instrument 3 is a well-known surveying instrument conventionally called “level”, and is mounted on the surveying instrument mounting section 100 of the support device 5.

The main body of the surveying instrument 3 has a built-in telephoto optical system capable of focusing. An eyepiece 31 is provided at one end of the main body, and an objective lens (not shown) is provided at the opposite object side. The surveying instrument 3 has, as its general configuration, an adjustment screw cover 33,
A slight increase screw 34 and a leveling screw 35 are provided. The laser oscillation device 4 is attached to the eyepiece 31 of the surveying instrument 3 at the portion of the second exterior body 22.

The laser oscillation device 4 includes a laser oscillation unit 1 and
First and second exterior bodies 21 and 22 are included. In the illustrated embodiment, the laser oscillation unit 1 includes an excitation unit 11 and a laser generation unit 12. The excitation unit 11 has an excitation circuit 14 mounted on one surface of a circuit board 13. Circuit board 13
Are arranged inside the first exterior body 21. On one surface of the circuit board 13, a conductor pattern 15 for forming an electric circuit is formed. With the conductor pattern 15, the excitation circuit 14 and the laser diode 17 of the laser generator 12 are connected to form a predetermined circuit configuration.

The first exterior body 21 is provided with a power supply connector 18. The connector 18 is connected to the circuit board 1
3, is electrically connected to the conductor pattern 15 formed on the top 3, is led out of the first exterior body 21, and receives a power supply of, for example, 6 VDC from the outside. The laser generator 12 includes a laser diode 17 and the like, and is disposed inside the second exterior body 22.

The second exterior body 22 is used as a portion to be attached to and detached from the surveying instrument, and emits the laser light generated by the laser oscillation section 1 to the outside from the tip end surface. The second exterior body 22 is provided with an attachment portion 221 for attaching and detaching to and from the eyepiece of the surveying instrument. Mounting part 221
Includes, for example, screws. In the figure, the second exterior body 22 has a block shape, and the laser generation unit 12 is set inside the second exterior body 22. In the second exterior body 22,
Hole 22 through which laser light emitted from laser generator 12 passes
2 is open.

FIGS. 15 to 18 are views for explaining a procedure for attaching the laser oscillation device 4 to the surveying instrument 3. However, this mounting procedure is shown for the sake of concrete description, and is not necessarily limited to this.

First, as shown in FIG.
The half washers 231 and 232 are fitted into the grooves 311 of the eyepiece 31 removed from the eyepieces 31. And FIG.
As shown in (2), a ring-shaped fastener 24 is attached to the eyepiece 31 from the side opposite to the laser oscillation device 4.

Next, as shown in FIG. 17, the fastener 24 is screwed into the mounting portion 221 of the laser oscillation device 4. As a result, the eyepiece 31 of the surveying instrument 3 is
1, 232 and the fastener 24, the laser oscillation device 4
Attached to.

Next, as shown in FIG. 18, the eyepiece 31 on which the laser oscillation device 4 is mounted is mounted on the eyepiece mounting part 312 of the surveying instrument 3. Thereby, the laser oscillation device 4 is attached to the surveying instrument 3. The laser light generated by the laser oscillation unit 1 passes through a hole 222 provided in the second exterior body 22 and is incident on the eyepiece 31 of the surveying instrument 3. The optical axis O1 of the laser light of the laser oscillation device 4 is aligned with the optical axis O2 of the telephoto optical system of the surveying instrument 3.

Power is supplied to the connector 18 of the laser oscillation device 4 from a battery 50 attached at an appropriate position such as an upper portion of the surveying instrument 3.

After making the necessary adjustments for the survey, the battery 5
The 0 switch 51 is turned on, the laser oscillation device 4 is operated, and laser light is generated. From the laser oscillation device 4,
Laser light L1 incident on the eyepiece 31 of the surveying instrument 3
Is focused by the telephoto optical system of the surveying instrument 3,
Irradiated on staff staff.

Optical axis O1 of laser light of laser oscillation device 4
Is aligned with the optical axis O2 of the telescope optical system of the surveying instrument 3, the laser light coincides with the origin of the reticle crosshair of the surveying instrument 3. Therefore, the scale of the light spot connected on the staff or the like matches the numerical value seen by the surveying instrument 3. Therefore, a person having a staff or the like can know the position of the surveying instrument 3 from the position of the light spot, and thus can accurately read the scale on the staff or the like. If necessary, the person who operates the surveying instrument 3 can leave the surveying instrument 3 and check the scale on a staff staff or the like. For this reason, it becomes possible to read the value of the scale on a staff or the like accurately and reliably, and to measure the value accurately.

Moreover, since the laser oscillation device 4 is used independently of the surveying instrument 3 and attached to and detached from the eyepiece 31 of the surveying instrument 3, it differs from a surveying instrument in which the laser oscillation device is integrated. The structure is simple, and it is extremely effective for cost reduction.

The laser oscillator 4 can be removed from the surveying instrument 3 by reversing the procedure shown in FIGS. Thereby, the surveying instrument 3 can be provided for use as a general surveying instrument.
