DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. In the figure, a slide staff 1 is composed of a main measuring rod 2 and a sub measuring rod 3 fitted outside the main measuring rod 2, and the main measuring rod 2 has an appropriate cross-sectional shape (rectangular in the figure). The first and second graduations 4A, 4B are formed on one side, that is, the surface, along the longitudinal direction on one side, that is, in the vicinity of the first graduation 4A. The read numeral 5A having one end face of the main measuring rod 2, that is, the lower end face as a zero reference is, for example, 10, 5, 20, 5, 30,.
In the vicinity of the second scale 4B, for example, read numbers 5B having the other end face of the main measuring rod 2, that is, the upper end face as a zero reference, are 10, 5, 20, 5, 30,. It is attached as follows.

The sub-rod 3 is formed in a tubular shape having an appropriate cross-sectional shape (in the figure, a rectangle corresponding to the main rod 2) and formed shorter than the main rod 2, and slides on the outer surface of the main rod 2. Mated as possible. The third and fourth scales 4A and 4B corresponding to the first and second scales 4A and 4B are provided on one side, that is, on the surface, of the auxiliary rod 3 in the same manner as the main rod 2 along the longitudinal direction. Scales 6A and 6B are formed, and near the third scale 6A, a read numeral 7A with the lower end face as a zero reference.
Are attached, for example, 10, 5, 20, 5, 30,..., And in the vicinity of the fourth scale 6B, a read numeral 7B with the upper end face as a zero reference is provided, for example, 10, 5, 20, 5,. , 30 ...
It is attached as follows.

A mounting member 8 for mounting a detector W for receiving a measuring light such as a laser is detachably fitted to the outside of the sub-rod 3 and is fixed by means of screws 9 or the like. . The mounting member 8 is formed with a square window 8a so that the third and fourth scales 6A and 6B of the sub-rod 3 and the read numbers 7A and 7B can be visually recognized, and an index mark 8b is provided on a part thereof. In addition, the detector W
Are removably mounted.

The slide stuff 1 of this embodiment is configured as described above, and a case where the height of the horizontal position is measured using a measuring light such as a laser will be described.

An attachment member 8 is provided at a predetermined portion of the sub-rod 3.
The slide staff 1 with the detector W attached thereto is installed at the measurement site via a laser beam, and measurement light is emitted toward the detector W from a laser body (not shown) set at a horizontal position to be measured. The horizontal position is measured by receiving light from the detector W, and the light receiving position of the detector W is matched by sliding the sub-rod 3 to the main rod 2 in the vertical direction. is there.

The height from the floor, for example, from the floor surface in the above-described measurement of the horizontal position, is determined when the lower end portion of the main measuring rod 2 is in contact with the lower part, for example, the floor surface. The size from the zero on the first scale 4A to the scale where the lower end face of the auxiliary rod 3 is located (read numeral 5A), and the detector from the lower end face of the auxiliary rod measurement 3, that is, the zero on the third scale 6A. The dimension (read number 7A) is read as it is up to the scale pointed by the index mark 8b of the mounting member 8 to which W is mounted, and is obtained by adding this. Further, the height from the ceiling, for example, from the ceiling in the measurement of the horizontal position, may be determined in a state where the upper end of the main measuring rod 2 is in contact with the upper, for example, the ceiling.
Of the second scale 4B from the zero to the scale at which the upper end face of the sub-rod 3 is located (read numeral 5B);
, The dimension from the zero of the fourth scale 6B to the scale indicated by the index mark 8b of the mounting member 8 on which the detector W is mounted (read number 7B) is read as it is and obtained by adding these. Things. That is, in this embodiment, the reading numbers 5A and 5B of the main measuring rod 2 and the reading numbers 7A and 7B of the sub measuring rod 3 which are continuous with the reading numbers 5A and 5B are read. The distance from the light receiving position of W to the lower part and the distance from the light receiving position of the detector W to the upper part can be obtained.

The slide stuff 1 of this embodiment can be used as a normal measuring rod in addition to the above-described horizontal position measurement. Can also be.

[0014]

[Effects of the Invention] As described in detail above, the present invention provides a laser
Horizontal position by the detector and the index mark that receive the measurement light
The distance from the light receiving position to the lower part is easily measured by using the first scale of the main measuring rod and the corresponding scale of the sub measuring rod. Using the second scale and the corresponding scale of the sub-rod measurement from the light receiving position to the upper side
It is possible to measure the distance of the simple. For example, in a survey using a measuring light such as a laser, in the measurement of the horizontal position, the slide stap with a simple structure can be used.
Therefore, the measurement position can be read very easily and quickly, and the workability in the measurement can be improved.
