Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying instrument in which a graduation portion and a marking ink marking portion are slidably moved.

[0002]

2. Description of the Related Art Conventionally, a scale is raised or lowered, calculated by a surveyor from a reference height and a height to be changed,
There was a surveying instrument that remembered the calculated figure of the height to be displayed and collimated the figure.

[0003]

However, this has the following drawbacks. (B) Since the height must be calculated, it is easy to make a mistake at the time of this calculation. (B) Since I had to remember the numbers on the scales such as the staff, I was apt to make mistakes in the survey due to my assumptions and mistakes.

[0004]

[Means for solving the problem] In the body frame (1), the scale is started from the zero point and is displayed vertically. A black stamp (2) that can be slid is attached. The present invention is a surveying instrument having the above configuration.

[0005]

Operation: Hold the main body frame (1) with both hands and apply it on the standard height line, and then slide the scale zero mark plate (4) to match the height of the standard black line (18). After completion, firmly fix with the scale fixing screw (9). After completion, this time, check the scale of the scale body (3) with the scale stamp (3), check the scale of the scale (3) with the stamp stamp marking plate (5), and check the scale above and below the standard height line. Slide the minutes. After the completion of the movement, fix it with the fixing tightening screw (7). After the completion, loosen the scale fixing screw (9), this time install the scale zero mark plate (4) to the installed leveling instrument leveling instrument high / collimation line (1
Collimate to 9), and align the mark on the scale zero mark plate (4). After the completion, the scale is fixed with a fixing screw (9).
As a result, the main body is collimated to an arbitrary position with an instrument, and the mark of the zero mark plate (4) on the graduation section is used to measure the high and collimation line (1
9) Move the main unit up and down to check the collimation, then release the stamp cover (6) on the main body of the stamping stamp (2) and press the stamping button (8) to mark and stamp the stamp. To do. This is repeated sequentially. By the above, the new display height (20) is displayed and the survey can be performed.

[0006]

EXAMPLES Examples of the present invention will be described below. (A) In the main body frame (1), a graduation scale (3) is provided which starts from the zero point and is displayed vertically and which is slidable. (B) A slidable and movable black stamping stamp main body (2) for marking surfaces such as walls and skeletons is provided in the remaining frame other than the main frame (1) (a).

The present invention has the above-described structure. When using this structure, the body frame (1) is pressed with both hands and applied to the line of the standard height, and then the scale zero marking plate ( 4) is slid and moved to align with the reference height line and the reference black line (18), and after completion, fix with the scale part fixing screw (9). After the completion, this time, check the scale of the scale (3) on the main body (2) of the black stamp stamp with the black stamp mark plate (5) and check the standard height line and the standard black line. Slide up and down from (18). After the completion of the movement, fix it with the fixing tightening screw (7). After the completion, loosen the scale fixing screw (9) and then aim the scale zero mark plate (4) at the level of the installed leveling instrument at the height of the surveying instrument / collimation line (19). , Align the marks on the scale zero mark plate (4). After the completion, the scale is fixed with a fixing screw (9). With this, the main body is collimated with an instrument at an arbitrary position, and the main body is moved up and down so that the mark of the scale zero mark plate (4) is aligned with the surveying instrument height / collimation line (19). The stamp cover (6) of the main body (2) for stamping is released, and the stamp button (8) for stamping is pressed to mark and stamp the stamp. This is repeated sequentially. By the above, the new display height (20) is displayed,
You can survey.

EFFECTS OF THE INVENTION According to the present invention, marking work is performed instead of numerical survey work, and the calculation associated with this survey work is unnecessary. It is very reliable because it can prevent the mistake of surveying.
